Pay attention to the supervision and inspection of old house renovation and demolition projects.

The community where the owner is located

Prelude: It is said that this is the first time to visit a net friend's home. Bian Xiao didn't dare to slack off and arrived half an hour early. As a result, neither the owner nor the supervisor has arrived (the house has been rented out at present), so Bian Xiao had to wait in the community. Because there are many trees in the old community, mosquitoes are flying everywhere. Ding is covered in bags. A quarter of an hour later, the supervisor and the owner Miss Yuan arrived one after another. The shopkeeper, Miss Yuan, is beautiful and polite. When she saw us waiting outside the door, she kept apologizing and said there was a traffic jam on the road. I'm sorry to have kept us waiting so long. Hearing this, Bian Xiao felt warm. Well, before it's too late, let's start looking at the house today!

Let's start with the entrance door!

Problem 1: the entrance door is loose, the door leaves are unstable, and the hinges are rusty and aging.

The door of Miss Yuan's house was changed eight years ago. Although it is not as old as the house, it is not suitable for use because it is next to the kitchen and has been corroded by oil smoke for a long time.

Supervision suggestion: the public security situation of the husband's family is not very good, so it is best to use the double insurance method of security door and wooden door as the entrance door.

Tips:

Security door purchase time:

Because security doors will be installed during hydropower construction, orders are usually placed before construction. Recommended brands: Buyang security door, Pan Pan security door, Xingyueshen security door, etc. The price range is about 1000-4000.

classify

The security door can be divided into four grades according to its security grade: A, B, C and D, among which the security performance of Grade A is the highest, Grade B is the second and Grade D is the lowest. Nowadays, most of the shopping malls are D-class security doors, which are more suitable for ordinary residents and consumers.

Materials:

Security doors are mainly divided into five types in terms of materials: steel, steel-wood structure, stainless steel, aluminum alloy and copper.

Precautions for purchase: First, the seller is required to show the inspection certificate of relevant departments to check whether it meets the technical requirements of the national mandatory standard GB 17565- 1998.

2. Remove the cat's eye, doorbell box or lock handle and check the internal structure of the door body. There should be several reinforcing ribs on the door to organically connect the front and rear panels of the door body. It is best to use asbestos and other materials with fire prevention, heat preservation and sound insulation functions as the door filler.

Third, check whether the lock is equipped with a special anti-theft lock that has passed the inspection by the public security department, and whether the lock installation place is protected by reinforced steel plates.

Fourth, check the process quality of the product, whether there are welding defects, and whether the cooperation between the door leaf and the door frame is dense.

Fifth, weigh the weight of the security door. The weight of a regular security door is not less than 40 kilograms.

In addition, when consumers buy security doors in the market, it is best to buy them in a regular large-scale home building materials city. Because if you want to go to the regular building materials city to sell security doors, you must obtain the approval of the special police branch of the Public Security Bureau, and the building materials city generally requires the settled merchants to provide relevant certificates for selling security doors. Generally, well-known security doors have sales points or specialty stores in building materials city. In addition, you should also check the production registration approval, quality verification certificate, inspection report and so on.

After watching the door, I was looking at the kitchen wall.

Problem 2: The kitchen tiles are seriously hollowed out.

There are several main reasons for the hollowing of ceramic tiles: the plastering of the wall foundation is not standardized, there is no soaking before paving, and the mortar is not full when paving bricks.

Supervisor's suggestion: when shoveling the wall skin of the old house, the kitchen wall skin must be shoveled until the red brick is shoveled, so as to avoid the wall cracking caused by the incompatibility of the old and new wall materials. Please be sure to soak the tiles in water for 2 hours before paving.

Charge for shoveling wall skin

5 yuan shoveled the wall left and right/_, scraped the putty and leveled it 8- 10 yuan, adding up to 15 pieces of wall foundation treatment/_. (depending on the charges of different services)

Matters needing attention in kitchen tile selection:

First of all, choose the color of ceramic tiles and the style of plastering according to personal hobbies.

Second: color. The walls of the kitchen generally choose bright and light-colored wall tiles, because the kitchen gives people the feeling of being clean and tidy, relaxed and cheerful, and the color is too dark, which will seem a little depressing. If you consider using matt as the wall of the kitchen, you'd better choose flat, not those with concave and convex feeling, mainly because it's not easy to scrub.

Third: specifications. Floor tiles must not be larger than 300*300, mainly for good slope and drainage of the ground.

Fourth: material. It is best to choose glazed tiles made of matt and non-slip materials to prevent the kitchen soup from making the ground too slippery, which may cause safety problems if you are not careful. Therefore, the choice of non-slip floor tiles is first of all the quality problem of bricks, which must be completely impermeable. So there is no worries.

Fifth, the price: 300*300-4.5 yuan 3.00, 300*450-7.0 yuan 6.00, 300 * 600 8.00- 10.

After looking at the wall, I will look at the cabinets and kitchen pipes of Miss Yuan's house.

Problem 3: The door panel of the cabinet can't be closed, the hinge is loose, and the tile on the countertop falls off; The kitchen gas pipeline is seriously aging, and the arrangement of smoke pipes is unreasonable.

Miss Yuan's kitchen should be regarded as a typical kitchen layout in the 1980s. The countertops of cabinets are made of cement, and cabinets are made of carpenters. Originally, the countertops and cabinets were not well closed. After a long time, the gap is getting bigger and bigger, which is easy to attract bugs to climb in. The distribution of gas pipes and water heaters is unreasonable, which makes daily cooking very inconvenient. In addition, the water heater is not made into a protective box, the kitchen fume corrodes the pipeline, and the parts of the water heater are easy to rust and age. Therefore, combined with the owner's idea, the supervisor suggested replacing the gas pipeline and installing a protective box for the water heater.

Tips:

Cabinet ordering time

Because the cabinet needs to be tested twice, the initial test in hydropower stage and the second test in mud and wood stage, in order to ensure the smooth progress of the construction period, it is best to order the cabinet one week before the start of construction.

Cabinet procurement should be 10 q:

First ask the thickness of the cabinet board.

Second, ask whether the cabinet is independent.

Third, ask whether to prevent cockroaches and seal the edges silently.

Fourth, ask about the composition of artificial stone.

Fifth, ask whether the artificial stone installation is dust-free.

Sixth, ask if you can provide the test report.

Seventh, ask the assembly method.

Eight questions: How to seal the backboard?

Nine questions on the installation method of aluminum foil in sink cabinet

Ten problems about warranty period

Gas pipeline shunt

In general, we don't recommend replacing the gas pipeline unless it really affects the use of daily functions. If the owner wants to change the gas pipeline, he needs to apply for property approval in advance, and the diversion work needs to be operated by professionals of the gas company. General charge 150 yuan (20 liters). After seeing the kitchen, let's study the circuit distribution of the old house.

Question 4: There is no difference between strong and weak boxes in old houses, and there is a lack of weak boxes.

Generally, in older old houses, household electricity consumption is rarely partitioned, so one wire or several wires are pulled through the wall to enter the house, and there are not many appliances in the house, so an electric box covers all the wires. The 30-year-old house simply concentrated all the lines on one board, and then simply diverted. Such a simple operation, with the increase of electricity consumption, will bring persistent and potential safety hazards to the space.

Supervision suggestion: after the new renovation, the circuit should be rectified, and strong and weak current boxes should be installed to avoid strong and weak current interference, stabilize the voltage and realize safe electricity use.

Tips:

What are strong wires and weak wires?

A strong electric box is simply a distribution box. The voltage in the distribution box is generally 380/220V, which is used to distribute electric energy and maintain the use of household lighting and main high-power appliances. The following can be equipped with lighting, air conditioning, refrigerator, fan, water pump and other electrical equipment. Weak wire: As the name implies, it is a concentrated box of weak current lines, which is generally used in modern home decoration, such as network cable, telephone line, computer monitor, USB cable, VGA, color difference and antenna of TV.

After talking about the circuit problem of the old house, let's talk about the main problems of the wall of the old house.

Question 5: the wall is empty, the wall paint is peeling, and it is alkali resistant.

Although Miss Yuan's family did a wall painting and painting five years ago. However, due to the incomplete eradication of the wall foundation, the old and new materials do not match, and the bonding is not firm. It is also the painter on the road who is looking for it. Five years later, the wall was empty and the paint began to fall off. In addition, due to the quality problems of the cement used before the old house and the fact that the walls were not treated with alkali resistance, some walls began to show alkali resistance.

Director's suggestion: the bedroom wall should be torn down. Because the humidity of the bedroom is not as high as that of the kitchen and bathroom, you can keep the grassroots when shoveling the wall skin. In order to strengthen the wall, you can use grid cloth and bandage to strengthen the wall, and use putty powder brush to level it. As for the problem of alkali resistance, alkali-resistant coatings can be used.

When looking at the problems of peeling of wall paint and hollowing of wall surface, the filling supervisor has made horizontal and vertical detection of all the yin and yang angles in the room.

Question 6: The internal angle of the master bedroom is uneven and the door cover is skewed.

Because of the technical problems in construction and people's low requirements for housing, the angle of Yin and Yang will be more or less uneven.

Supervisor's suggestion: plaster lines are recommended for all rooms in the old house to reinforce the internal corners and make the walls look more regular and beautiful.

Tips:

What is Yin-Yang Angle?

The yin-yang angle of the wall is one of the architectural structures. The yin-yang angle of the wall refers to the concave corner, such as the angle between the top surface and the surrounding wall. The external angle of the wall refers to the protruding angle, such as the angle between the window opening and the wall.

The picture shows the uneven corner of the aisle, and the corner has a watermark.

Director's suggestion: In order not to leave hidden dangers, all the old wall skins should be removed, especially the corners. In addition, the wall must be smooth when the internal angle is constructed. Before plastering, find the square according to the rules, pull the wire for leveling, hang the vertical line straight, and pop up the baseline and dado line. Check the flatness and verticality of the wall surface with the supporting plate first, and then decide the plastering thickness. When wiping the angle of Yin and Yang, check the founder of the angle of Yin and Yang at any time and correct it in time. Check the wall for cracks. If there are cracks, carefully daub them with plaster. It is best to coat the corner with waterproof material or cement mortar.

Because the husband's room area is not large and the bedroom area is too small, the living room takes into account the function of the master bedroom.

Problem 7: Some furniture paint falls off, the door panel is deformed, and the wall function is not well played.

Most of the furniture in Miss Yuan's home has been used for more than 10 years, and most of them are panel furniture. After a long time, the paint skin of some furniture has fallen off and the door panels have been deformed. Look at the wall of the owner's house, whether it is the pink blue in front of the master bedroom or the second bedroom. Of course, this refreshing and uncomplicated color is very suitable for small-sized apartments, but if some clever changes are made on the wall, it will stimulate the aesthetic function and storage function of the wall.

Regulatory suggestion: furniture can choose some integral furniture with strong storage function. From the perspective of economy and environmental protection, Shimizu Cunninghamia lanceolata laminated board will be a good choice with strong natural bearing capacity. In addition to painting, you can choose elegant wallpaper or stickers for wall decoration and make some shelves. It is also good to put some decorations and books in peacetime.

Because the light in the second bedroom is broken, we can't take pictures of the second bedroom, but after watching the second bedroom, the owner still asked the supervisor about his concerns. One is the lighting problem of the second bedroom, and the other is that there is a wall near the stairs in the second bedroom, and the sound insulation effect is not very good. Is there a good solution? The supervisor also gave an answer to this.

Supervisor's suggestion: Generally, lighting can be expanded by installing glass sliding door through opening the wall, but the light blocking wall where Miss Yuan lies next is a load-bearing wall, which cannot be destroyed. Therefore, the director suggested that in the choice of light source and the color of wall paint or wallpaper, you can choose bright warm colors to avoid cold colors and dark colors. About sound insulation. The supervisor suggested that sticking soundproof cotton and soundproof board on the wall can solve the problem.

After seeing the master bedroom and the second bedroom, the supervisor went to the bathroom to have a look.

Question 8: The bathroom tiles are seriously hollowed out, there are many watermarks on the tiles, the ground is not inclined, and the ceiling gusset plate is inclined.

Toilets in old houses are rarely waterproof, so the walls swell after absorbing water, which leads to cracks in tiles and the watermark does not return. In the past, the ceiling of the bathroom was mostly pvc board, which was light but easy to corrode and bend.

Oversight recommendations:

The bathroom needs to be waterproof, the wall should be at least 180cm, and the top should be painted with waterproof paint. It is best to choose the integrated aluminum gusset ceiling for the ceiling.

Tips:

Waterproof:

General mortar and mortar are mainly used for waterproofing. Waterproofing is mainly done in the bathroom and can also be done in the kitchen. Generally, the bottom surface must be waterproof and can be tested in the form of 24-hour closed irrigation. The height is about 20 cm. If it is the partition wall between the faucet and the bedroom, it is recommended to make1.8m to prevent the permeable wall from becoming moldy.

Integrated ceiling:

Integrated ceiling is a combination of metal square plate and electrical appliances. It is divided into heating module, lighting module and ventilation module.

How to distinguish the advantages and disadvantages of pinch plate?

A, look: the surface of inferior pinch plate looks uneven and there will be particles. The quality board looks flat and the panel is soft.

B, smell: use a lighter to light a corner of the inferior board, it will burn in 30 seconds, and there will be a pungent smell of plastic burning. Even if the oil-resistant ceiling is burned yellow, there will be no pungent smell.

C. Touch: The temperature of the laminated board is the temperature of plastic, so it is relatively high and should be warmer. The temperature of roller coating plate is the temperature of metal, so it should be cooler.

D. Listen: Hold one corner of the panel with your hand and tap the center of the panel gently, so that the sound of the coated board is low and the sound of the roller coated board is crisp.

Question 9: The floor is painted and uneven in some places.

Miss Yuan's floor should be regarded as an antique. It has been used for 10 years. Long-term lack of maintenance led to paint falling off the floor, and the floor leveling work was not done well, resulting in uneven floor.

Director's suggestion: It is best to replace all the decorated floors in the old house. According to the requirement that the owner wants to replace it with a composite floor, the supervisor said that it is not necessary to have a keel floor, but in order to increase the sense of feet, the old floor that was originally removed can be used as a rough floor and laid under the moisture-proof film. However, it should be noted that the rough floor requires the ground to be very flat, so the ground should be leveled first, and the old floor should be leveled, dry and clean after being removed. Leveling the concave and convex parts with a shovel. If there is obvious slope or depression in a small area after leveling, 30% coarse sand mixed with gypsum binder can be used for leveling, and the floating ash or other impurities on the surface will be swept away after being thoroughly dried before laying.

Tips:

Buy composite flooring

Finally, the focus is on the demolition of old houses.

General decoration companies are not responsible for demolishing old buildings. If the owner wants the decoration company to demolish the old building, it will involve demolishing the old building. Moreover, the demolition costs of various decoration companies are inconsistent, and there is no clear regulation on the demolition of old buildings in the industry. Perhaps many owners will find street guerrillas or old demolition companies to do it for the so-called cheapness, but due to the lack of professional knowledge, it is easy to damage houses during the old demolition process, and all the ones that should not be demolished are demolished. Moreover, the usual measure of road guerrillas is to quote a low price, which is quite ruthless during construction. Therefore, the demolition work is best done by the decoration company. In order to avoid excessive collection of demolition fees by decoration companies, they must make a detailed list, which places are to be demolished, how much is the single charge, and how much is the total cost, and clearly stipulate the signature of both parties. Otherwise, as the old ones are demolished one by one, the cost will rise.

Problems needing attention in demolition of old buildings

Summary: After more than two hours of inspection, Bian Xiao really learned a lot of knowledge while the supervisor pointed out that there were many problems in the owner's house. Hope to pass
