What is the process of interior decoration?

After the design is completed and the budget is determined, we can start work.

(1) Property related procedures

The decoration company will bring a copy of the business license and relevant design drawings, and go to the property company with you to go through the relevant formalities. Remember to bring enough cash, first of all, you need to pay the decoration deposit, the general amount is 2000 yuan, and the owner and the decoration company pay 50% each. However, it is recommended that all of them be paid by the owner, because if the decoration company pays, there is basically no return. Pay the property management fee, buy water and electricity, and the decoration company needs to apply for the construction personnel pass.

If the house is closed on the same day, the property company will send people to suppress, test the water and check the electricity.

(2) Site design disclosure:

The so-called design disclosure means that on the first day of construction, the designer takes a full set of design drawings to the construction site and makes disclosure to the project supervisor. Project supervision is generally experienced in the field. In the process of design disclosure, some design omissions can often be found, and designers will be required to make design modifications. Workers carry out construction in strict accordance with the design drawings, so once design errors and omissions are found, designers must immediately modify the design, and after the design modification, the budget should be adjusted accordingly.

(3) hydropower positioning:

The hydropower part generally needs to be reformed. The basic principles of hydropower transformation are as follows: the waterway behind the water meter is completely transformed and the pipeline is re-laid; Generally, the original circuit is used as much as possible, and only local modifications or additions are made.

Because the cost of hydropower transformation is generally settled in advance and truthfully immediately after completion, it is easy to be ensnared carelessly, and the actual settlement amount greatly exceeds the amount received in advance.

In order to protect the interests of consumers, the project supervisor must first clearly tell the owner that the pre-payment of hydropower transformation in the budget can complete those projects. Waterway reconstruction is generally simple, and it can meet the needs of toilets, kitchens, washing machines and mopping pools. The key is to pay attention to whether the circuit transformation can meet your needs.

The project manager should tell you what he can do for you according to the amount received in advance, and draw them on the wall one by one. If additional increase is needed, you must also tell you clearly how much the added part needs to be increased.

(4) find the level

When a mason enters the field, the first thing to do is to find a good level. Now, laser levels is generally used to directly play the horizontal line on the wall, and then play the ink line. Without laser levels, we can only use the old method of injecting water into transparent plastic pipes to find the level.

(5) smash the wall to build a wall

If there are old walls to be demolished and new walls to be built, workers will carry out the construction according to the design drawings.

Designers should be familiar with the building structure, and be careful when removing or moving the wall: the load-bearing wall cannot be removed; The beam can't be smashed; In the case of no beam below, generally do not build a new wall directly on the ground, even if you have to build a new wall, you should use lightweight bricks; Don't remove the bathroom wall easily to prevent the original waterproof structure from being damaged.

In order to make full use of the space, some owners are whimsical and require to smash half of the 24-story wall, while some designers design according to the requirements of the owners. We should know that the existing walls are hollow bricks, even light bricks. When the sledgehammer hits them, the whole wall will collapse. It is impossible to smash half of them unless they are all smashed for reconstruction, but it costs money to smash reconstruction.

The wall must be built with new bricks and the red bricks must be watered first. Horizontal and vertical lines must be hung properly. At the joint between the new wall and the old wall, the original cement mortar of the old wall must be removed first, two holes with a depth of 5-8 cm should be drilled in the old wall every 10 brick, and then two 6mm steel bars should be inserted side by side, and the steel bars left outside with a length exceeding 15cm should be buried in the new wall to ensure the stable connection between the new and old walls. The bonding surface of new and old walls should be hung with 20-30 cm wide steel wire mesh before plastering.

(6) Handling at the door

The height of the standard door leaf is generally 2 meters, and the highest is about 2.2 meters. If the doorway exceeds this height, it must be treated.

Many decoration companies use gypsum board to treat the keel, and then scrape it with putty and paint it. After a long time, cracks will inevitably appear at the joint between gypsum board and brick wall.

The correct construction technology should be pouring cement lintel now, adding at least 3 8 mm steel bars inside the lintel, filling it with bricks after the lintel is installed, and then batch cement mortar.

(7) flue treatment

Because there are many residents in high-rise buildings and the flue temperature is particularly high, a layer of cement mortar should be added after the flue is hung, otherwise the tiles will fall off easily in the future.

(8) Wall plastering

The newly built wall must be watered before plastering, the red brick must be thoroughly watered, and the light brick should be moderately watered. Pay attention to ensure that the wall is flat when approving the ash.

(1) waterway reconstruction

1. Heaven and Earth

There are two methods for waterway reconstruction, one is "going to heaven" and the other is "going to the ground". These two methods have their own advantages.

The so-called Heaven means that the pipeline is installed on the ceiling, which is suitable for installing a ceiling through the route, on the grounds that it is convenient for future maintenance. However, long-term exposure to air will easily lead to aging of pipelines, which will affect their service life.

The so-called underground, that is, all pipelines are buried underground, the disadvantage is that once leakage occurs, it is more difficult to maintain. At present, most of them are basically buried.

2. Go straight, horizontal and vertical

There are also two methods for pipeline alignment, one is to take the shortest straight line, and the other is to pay attention to horizontal and vertical. Generally speaking, the latter is more.

3. Install the main valve

Some real estate water meters are installed downstairs, and there is no main valve after entering the house. A main valve should be installed for future maintenance.

4. Hot water pipe insulation

Hot water pipes generally have insulation layers. But the insulation layer should not enter the kitchen and bathroom, because there is often water in these parts, which can easily penetrate into other areas through the insulation layer. This is the practical experience summed up in the process of use.

5. Pipe diameter

Generally, 25mm pipes are used for main water pipes and 20mm pipes for branch pipes. It is also a popular trend to use all hot water pipes. The only difference between hot water pipeline and cold water pipeline is the different wall thickness of the pipeline.

6. Keep a reasonable distance between hot water pipes and cold water pipes.

7. Pipe joint

The pipe connection adopts hot melting method, and the key technology is to master the hot melting temperature.

8. The position of the internal teeth bending

The so-called internal tooth bend refers to the internal lead bend of the connected faucet, and its position is particularly important. One is not crooked, and the other is to be flat with the tiles. In order to ensure the correct position, the plumber should not use cement to fix it immediately after installation, but use wood square to fix it temporarily, and position himself when the bricklayer lays the wall tiles.

9. Treatment of pipeline intersection position

At the intersection of pipes, the bridge should be bent, so that after treatment, it only occupies the height of one water pipe and will not raise the ground extra.

10. Waterway quality inspection

After all pipelines are installed, they must pass the pressure test. Generally, it can be pressurized to10kg for more than 2 hours. If the pressure basically does not drop, the project quality is qualified.

1 1. Check whether the water is unblocked.

Pay attention to check whether the sewer pipe is clear. If it is found that the sewer pipe is not smooth, the general reason is that during the construction process, the sewer pipe falls into cement mortar and blocks the pipe. You can go downstairs and open the manhole to clear it.
