Is it necessary to replace broken bridge aluminum in high-rise buildings?

Is it necessary to replace broken bridge aluminum in high-rise buildings? Now family decoration will decorate sliding windows, which is safer, more flexible and more convenient than casement windows. However, many masters recommend broken bridge aluminum when installing and purchasing sliding windows. Is it necessary to replace broken bridge aluminum in high-rise buildings?

Is it necessary to replace broken bridge aluminum in high-rise buildings? 1 1: There is a quality supervision department to supervise the quality of real estate. The same is true of broken bridge aluminum doors and windows. Before production, it must be tested by the regulatory authorities, and all aspects must meet the national standards before processing and production. For example, the thickness of broken bridge aluminum must meet the national standard (1.4mm or more), and the surface coating also requires environmental protection.

2. Broken bridge aluminum is the best material for doors and windows (heat insulation, sound insulation, dust prevention and aging resistance) at present, and there is no material with better performance to replace it.

The advantages of broken bridge aluminum are mentioned above. By the way, what should be paid attention to in broken bridge aluminum doors and windows? Broken bridge aluminum is sealed because its sealing strip can not be ignored. The sealing strips on the outer frame and sash should be fastened in place. There is also the waterproof treatment of broken bridge aluminum, and the outer wall and window frame should be sealed with weather-resistant sealant, and there can be no gaps. In terms of hardware accessories, the window sash can be opened and closed freely without abnormal sound.

Conclusion: Broken bridge aluminum has been widely used because of its superior performance, and good things need to be maintained. Always check the fixing screws of the window sash, reinforce them if they are loose, replace the sealing strip if there are cracks and shrinkage, and add some butter if there are obstacles.

There are several reasons why I encountered the replacement of broken aluminum. One is to change the structure of the house, the other is to change the window type (push and pull for leveling), and the other is to abandon the developer's doors and windows and replace the broken bridge aluminum with a local tyrant who imitates wood grain. If you replace the broken aluminum doors and windows, which one do you belong to?

Is it necessary to replace broken aluminum in high-rise buildings? 1. What are the advantages of breaking aluminum doors and windows?

1, good sound insulation effect.

Modern houses are mostly elevator rooms with dozens of floors. The higher the floor, the greater the wind noise, and the sound insulation effect of broken bridge aluminum doors and windows is very good, which just meets the needs of most people today. Because the broken-bridge aluminum doors and windows are made of aluminum alloy, they are not only thick in texture, but also very close in joints, and will be equipped with sealant and adhesive tape later, so the sound insulation effect of the broken-bridge aluminum doors and windows is great. No wonder many people like to use it in home improvement.

2. Good heat preservation and impermeability.

Broken bridge aluminum doors and windows not only have good sound insulation effect, but also have good heat insulation and impermeability. According to experts and friends, if the renovated new house is equipped with broken aluminum doors and windows, the home will be warm in winter and cool in summer. Broken aluminum doors and windows will reduce the heat conducted through the doors and windows.

On the one hand, breaking aluminum doors and windows and adding heat insulation strips in winter can at least reduce the heat lost through doors and windows by 30%; On the other hand, indoor air conditioners are not easily lost through doors and windows in summer. In addition, outdoor rainwater is not easy to penetrate indoors in rainy days, which can avoid the occurrence of damp and moldy walls.

3, environmental protection and recycling

More importantly, the broken-bridge aluminum doors and windows are environmentally friendly materials, and the abandoned broken-bridge aluminum doors and windows can be disassembled and recycled, and no harmful substances will be produced in the manufacturing process.

2. What are the installation steps of broken aluminum doors and windows?

1. If the broken aluminum doors and windows are fixed with connecting iron pieces, the iron pieces should be treated with anti-corrosion, and the connecting pieces should be made of stainless steel or fixed with hot-dip galvanized M8 expansion screws.

2. Placement and temporary fixation: Pay-off and install according to the installation position, and lift and straighten. If there is no problem, temporarily fix it with a wooden wedge.

3. Fixed with the wall: doors and windows are fixed with the wall. The distance from the first fixed point to the window angle should not be greater than 180㎜, and the distance between fixed points should be less than 600㎜.

4. Treatment of the gap between the door window frame and the wall: After the door window is fixed, the gap between the door window frame and the wall should be treated in time. The varieties of filling materials should meet the design requirements, and the outer surface should be filled with caulking paste with a depth of 5 ~ 8 ㎜. It is forbidden to use cement mortar for filling. After the anti-corrosion treatment is carried out on the wall surface by the door window frame, the heat preservation materials and sealing materials specified in the design can be filled in. After the installation of the broken bridge aluminum alloy window and window sill plate, the gaps around the window frame should be filled at the same time, and the real-time force should not be too large to prevent the window frame from being deformed.

5, door frame installation. Repair the reserved door opening in advance according to the size of aluminum alloy door frame. Fix the connecting software (or wooden brick) on the side of the door frame. Door frames should be installed according to the position. After finding out the verticality and geometric dimensions, fix them with M 10 or M 12 hot dip galvanized expansion bolts. Fill the gap between the wall and the door and window frame with thermal insulation material. Fill the gap between the wall, door and window frame with sealing paste.

6. Installation of the ground spring seat: according to the installation position of the ground spring, remove the hole in advance, put the ground spring into the removed hole and fix it with cement mortar.

7. The installation quality of the floor spring must be guaranteed: the epithelium of the floor spring seat must be consistent with the indoor floor; The axis of the rotating shaft of the floor spring must be consistent with the axis of the horizontal positioning pin of the door frame.

8. Door leaf installation: The door frame fan connection is fixed by aluminum angle code, and the specific method is the same as the door frame installation.

9. The installation of hardware fittings requires firm installation and flexible use.

Third, how to maintain the broken aluminum doors and windows?

1, broken aluminum doors and windows cannot be cleaned with ordinary soap and washing powder, nor with strong acid and alkali cleaners such as detergent and toilet cleaner. You can wipe it with a soft cloth dipped in water or a neutral detergent.

2. Sealing wool tops and glass glue is the key to ensure the sealing, heat preservation and waterproof of broken aluminum doors and windows. If it falls off, it should be repaired and replaced in time.

3. When cleaning the broken aluminum doors and windows, never step on the aluminum frame or pull the frame to support it.

4, after the rainy day, should be timely dry glass and door window frame layering, pay special attention to the chute water. When the chute is used for a long time, the friction will increase. You can add a little engine oil or coat it with wax oil.

5, often check the junction of broken bridge aluminum doors and windows frame wall, if there is any loose over time, it is easy to make the whole frame deformation, so that doors and windows can not be closed and sealed. Therefore, the loose screws at the joint should be tightened immediately. If the screw base is loose, use a small amount of cement to seal it.

6, broken bridge aluminum doors and windows in the process of use, should push gently pull, push and pull let nature take its course; When you find difficulties, don't force them, but solve them first. Dust accumulation and deformation are the main reasons for the difficulty in pushing and pulling aluminum alloy doors and windows. Keep the door frame clean, especially the push-pull slot clean. Dust accumulated in the groove and top of the door sealing strip can be sucked away by vacuum cleaner.

7, often check the aluminum doors and windows frame wall junction, if there is any loose over time, it is easy to make the whole frame deformation, so that doors and windows can not be closed and sealed. Therefore, the loose screws at the joint should be tightened immediately. If the screw base is loose, use a small amount of cement to seal it.

When buying broken aluminum doors and windows, we should pay attention to choosing brands produced by regular manufacturers, and at the same time, we should pay attention to doing maintenance work. In daily life, we should pay attention to using towels regularly for cleaning, and at the same time, we should pay attention to regular inspection to avoid the deformation of damaged aluminum doors and windows, which will affect the normal life of family members and cause potential safety hazards.

Is it necessary to replace broken bridge aluminum in high-rise buildings? 3 1. What does broken bridge aluminum mean?

Broken bridge aluminum bridge refers to hot and cold bridge. As we all know, the heat transfer of metal is faster than that of brick cement. In winter, you may just feel cold when you touch the wall at home; But if you touch the unbroken metal window frame, it feels like ice. If the wall is a river, it blocks the heat in the house; The metal window frame is like a bridge, which continuously takes heat out of the house.

Broken bridge aluminum is to add a layer of insulating hard plastic between two metal frames to break the bridge, so that heat is not so easy to escape. The material of this layer of hard plastic is generally PA66, so it can't be lit. You can burn it with a lighter when you buy it.

2. How to choose the model of broken bridge aluminum?

The model of the broken bridge aluminum represents the width of its outer frame, that is, the place marked 60mm below. At present, the main product models of mainstream broken bridge aluminum manufacturers in the market are 60657080 and other models. The larger the model, the better the insulation and sound insulation effect of the broken bridge aluminum window. Sales data from manufacturers show that in 20 17 years, among the sales of different models, 60 models accounted for 50%, 70 models accounted for 40%, 65 models and 80 models accounted for 8% and 2%. It seems that the 60 and 70 models of broken bridge aluminum are the mainstream products on the market.

Generally speaking, the wall thickness of type 60 broken aluminum window is 1 and 4mm, and the glass hollow layer is 5+ 18a+5. It's time someone didn't understand. The wall thickness is very simple, that is, the thickness of aluminum plate, which is marked in the figure; But what does 5+ 18a+5 mean? It's very simple. Two sides 5 indicate that the glass thickness is 5mm, and the middle 18 indicates that the distance between two pieces of glass is18 mm.

Accordingly, the insulating glass layer 5+27a+5 of the model 70 means that the glass thickness is 5mm and the glass spacing is 27 mm. The wall thickness of the model 70 ranges from 1, 4mm to 1, 8 mm, and the thicker it is, the stronger it is, and of course it is more expensive.

Some people say that if I choose type 80, will the glass spacing be larger? Not necessarily ~ 80 models of some merchants, the glass hollowing layer is still 5+27a+5; Some merchants simply make it into a three-layer hollow ~ for example, as shown below. Specifically, you should ask the sales of the merchants.

Let's be clear here: there is dry air between the glasses, not a vacuum. It is too difficult to do vacuum, and the requirements for glass strength are also very high. General family decoration can't afford such a budget.

Generally speaking, if your community is far away from urban areas, streets and stations, and you are not particularly afraid of noise, and your city is not so cold in winter, then Type 60 is enough. But if your home meets one of the following conditions, we suggest that you install Model 70! First, the community is particularly noisy; Second, a large French window was installed; Third, the floor is relatively high; Fourth, the requirements for sound insulation are high. Car owners with old people and children at home can also consider Model 70.

As for the three-layer glass, it has advantages in heat insulation, so it is used more in Northeast China. As for sound insulation, you have to spend money to buy a peace of mind.

3. How to seal the broken bridge aluminum?

In order to obtain better heat insulation and sound insulation effect, the aluminum window of the broken bridge should be strictly sealed to prevent the hot air in the house from escaping from the gap of the window. At present, the raw materials of window frames produced by domestic large-scale broken bridge aluminum profile factory are all self-sealed, with two sealing strips for the outer window and three sealing strips for the inner window. But even this would not be enough Some consumers still complain that the windows are not well sealed and it will be very cold in winter.

But if more sealing strips are added, won't people in places that are not so cold in winter suffer a lot? Therefore, the manufacturer of broken bridge aluminum profile added a track inside the window where adhesive tape can be worn, so that the manufacturer of broken bridge aluminum can wear adhesive tape according to the needs of users, and users can wear as many as they want, so there are three, four, five, six, seven, eight, nine or even ten different levels of sealing design.

Some people will ask: where is the sealing strip installed? Of course, it is the contact point between the window sash and the window frame ~ The above picture shows the distribution of sealing strips of six sealed broken bridges of a certain brand aluminum window for your reference. When buying windows, you should also carefully observe whether these sealing strips overlap closely. If the overlap is not strict, more channels will only waste money.

In addition, the quality of sealing strip is also very important. Everyone should choose soft and elastic sealing strips, but those that feel hard and brittle can't be used!

Note: Some businesses have to pay extra for sealing strips. Please ask before buying!

In addition, supporting accessories such as beams, columns, flat hardware, locators, screens, waterproof glue, styrofoam, etc. You can also charge separately. When consulting the price of broken aluminum doors and windows, be sure to ask whether the above items are included.

As we all know, many businesses in the decoration industry have quotation traps. In order to attract customers, the unit price is quoted at a low price first, and then the merchants make up the difference by collecting various accessories, and the broken bridge aluminum merchants are no exception. These accessories usually cost several thousand yuan. Consumers thought they bought cheap windows, but when they added up the accessories, they found that they had suffered a big loss.

4. How to choose window hardware?

As the saying goes, "a fence has three piles, and a hero has three gangs." No matter how good the broken aluminum window is, it is still annoying to use it without good hardware. Take casement window as an example, its hardware includes handle, actuator, hinge, lock point, wind brace and so on. The quality of these parts will directly affect the smooth opening and closing and service life of broken aluminum doors and windows.

Good hardware is heavy, the switch is smooth but not loose, tight but will not feel jammed. When you buy, try to feel as much as possible, and the quality of the product can be distinguished by comparison.

When purchasing broken bridge aluminum door and window hardware, if you have enough budget, I suggest you choose German brand. Hardware produced by well-known German brand manufacturers is better than domestic hardware in workmanship quality and use effect. After all, doors and windows have to be kept for you for more than ten years, and they are often open and closed. Flexibility is very important ~

5. What should I do if I want to be more soundproof?

Some people don't sleep well, are afraid of noise, and are very concerned about the noise downstairs. They want to install more sound insulation glass. What should I do?

We recommend that you use laminated glass.

The hollow of insulating glass is an air layer, which has a good effect on medium and high frequency noise, such as screams. And laminated glass better isolates low-frequency noise. However, due to the large gap between broken aluminum, it is impossible to make all the middle parts into glue, right? And when insulating glass and laminated glass are matched, high, medium and low frequency noises are shielded, right?

Therefore, hollow laminated glass has become the best glass combination with sound insulation effect at present, which is suitable for airports, subways, ring roads and other places with high noise. If you need high-quality sleep, or you can't sleep with a little noise, you can consider choosing laminated insulating glass ~

6. Measurement and installation of windows

After choosing the window type, don't forget to make an appointment for the merchant to take measurements at home.

Changing windows is an important step in decoration, especially for second-hand houses. Its time node selection is critical. You can't let workers work in an open room, can you? And many processes in the decoration also need to be dried in the shade. So windows need to be installed before bricklaying and wall treatment. The general production cycle of doors and windows is 15-20 days. If it is the decoration season, the production cycle may be extended to 20-25 days.

In order not to delay your construction period, we suggest booking windows before the construction begins. During the 20-day window-making process, all the dirty work in your house, such as demolishing old buildings, shoveling wall skins, slotting water and electricity, is almost over. At this time, you can arrange window installation.

In addition, in order to coordinate as a whole, some communities will require the window type and color of each household to be unified. Don't laugh! This is true! In order to avoid the unqualified acceptance of the later renovated property and bring you unnecessary trouble, you should go to the property and ask if there are any uniform requirements before you place an order for windows ~

7, install windows should also pay attention to these!

The window is the first main material in the process of family decoration. Decoration materials related to windows include: kitchen basin, faucet, cooker, ceiling, air conditioner, curtain, clothes rail, window sill marble, wall brick or window cover, wall paint, wardrobe, cupboard, etc. These materials can only be installed on site after the windows are installed. Everything was planned first. In order to prevent the window from fighting with other main materials, before ordering the window, you should plan the decoration design of your home and make the following preparations:

(1) The sealing effect of casement windows is better than that of sliding windows, so most windows are casement windows now. However, once the position of the casement window and the fixed glass is determined, the manufacturer can produce as you say and cannot change it! It is suggested that you plan the position and opening direction of windows before ordering doors and windows, so as to avoid conflicts with the late main materials and affect the decoration process.

(2) The total price of broken aluminum windows is absolutely related to the number of open fans. The cost of a screen opening fan includes hardware, screen, positioner and raw materials, so the fewer screen opening fans, the lower the cost. And the fewer fans, the better for sealing and heat preservation. If it is not necessary, we actually don't recommend you to be too many fans ~

(3) Confirm in advance whether the kitchen and bathroom appliances should go out from the window. If water heater pipes, smoke exhaust pipes of range hood brands, or air conditioning pipes need to pass through windows, holes should be punched in the glass.

Then when you sign a contract with the merchant, you need to confirm the position and diameter of the hole in the glass, so as to prevent the manufacturer from placing an order for production because of a hole, and finally delay your own construction period. However, try not to make holes in the window glass. When it rains, rainwater will be stored in insulating glass, which will affect the thermal insulation performance and not look good.

(4) Before measuring the window, it is necessary to confirm whether the ceiling or curtain rod is needed at the top of the flat window. If you plan to install it, let the opening fan avoid the ceiling or curtain rod when designing, otherwise your window may not open in the future ~

(5) Similarly, if your window opening is going to be paved with marble or pasted with a window sash, make a plan in advance, and communicate with the merchant before ordering to avoid the window sash being unable to open when it fights with the window sash later.
