Demolition of old houses
The demolition works seem simple, but they are not simple at all. Many owners think that the demolition work is simple and find someone to demolish. I once saw an owner who was very anxious and found a few powerful handymen directly downstairs, but these handymen did not understand what should be dismantled and which should not be dismantled in the demolition project. The sledgehammer was smashed ... As a result, when the master of the decoration company came to work the next day after the smashing, he found ... there was a problem in the kitchen circuit! It turned out that when the handyman widened the kitchen door, he broke the circuit buried in the wall! The water in the bathroom is impassable! Upon inspection, the original floor drain was filled with bricks and ash!
What's even worse is that the owner's neighbor came to the door and said that the bathroom was separated from the owner's bathroom. The tiles on the wall were cracked and asked the owner to compensate him! This shows that the renovation and demolition of old houses must not be handled by handymen who do not understand professional decoration knowledge, otherwise it will cause more trouble to themselves.
Demolition of doors and windows of old houses
The aging of doors and windows is a prominent problem in old houses, but if the material is sturdy, you also like the original style. Generally speaking, as long as the paint is repainted, you can get a new look, but if the wood doors and windows are peeled and deformed, they must be replaced with new ones. .
In addition, the peeling of the paint film on the surface of the steel doors and windows, the corrosion or cracking of the main body, in addition to being unsafe, it is difficult to restore the original state, in order not to affect the use effect, it should also be removed and redone.
Demolition of the old building wall and ground
If the wall skin is water-resistant putty, it is difficult and unnecessary to shovel it, so it can generally be kept. The repainting process can be directly painted after sanding with sandpaper, or you can hang two more layers of putty and paint again. If the wall has small cracks If it is more, it is necessary to stick the kraft paper or even a good cloth first; if the wall skin is not water resistant putty, it is best to shovel it out again.
When smashing wall tiles and floor tiles, avoid debris blocking the sewers . Note that only solid wood floors, solid wood composite floors and bamboo floors with a surface thickness of 4 mm can be renovated . In addition, partial refurbishment will also cause differences between the old and new floors, so one cannot blindly renovate the floor.
Demolition of the old house
In general, the original waterway pipelines in the old house have many unreasonable layouts or are corroded, so the decoration master needs to thoroughly check the waterway. If the original pipeline is a galvanized pipe that has been eliminated , it must be replaced with copper pipe, aluminum-plastic composite pipe or PP-R pipe during construction.
Demolition of the old house
The old houses generally have simple circuit distribution, wire aging, illegal wiring and other phenomena, which can no longer meet the electricity demand of modern families, so they must be completely renovated and re-wired during decoration.
Since the previous wires used aluminum wires, they need to be replaced with copper wires, and PVC insulated wire protection pipes should be used, and the lines for installing high-power electrical appliances such as air conditioners should be run separately.
As for the socket problem, it is necessary to add more sockets, because the sockets in the old house cannot reach the number of electrical appliances currently used.
Waterproof for concealed works
Brush the first pass of waterproof coating: make sure that the construction site is clean and dry before construction. The waterproof coating must be filled with no omissions, firmly combined with the base, without cracks, bubbles, and shedding; the height of the coating is consistent; the thickness must meet the product requirements .
Brush the second pass of waterproof coating: Note that there is a certain time interval between the first and second passes of the waterproof coating, and the second pass can only be performed after the first pass of the paint is dry, depending on the paint. If the interval is too short, the waterproof effect will be greatly reduced, so everyone should pay attention to whether the construction workers have completed all the procedures.
Paving a protective layer: In order to prevent the subsequent construction from damaging the waterproof layer, a protective layer needs to be laid on the surface of the waterproof coating. The protective layer should completely cover the waterproof layer, without omission, firmly combined with the base layer, without cracks, bubbles, and shedding phenomena.
Water shut-off test: During the water shut-off test, the water at the highest point on the ground should not be less than 2 cm , and it should be stored for at least 24 hours. Observe that there is no leakage before it is qualified. If there is a leak, it needs to be redone, don't feel indifferent.
Waterway for concealed works
Replace the water valve. The waterway of the old house is mostly galvanized pipe, which is easy to rust, scale and the open pipe is not beautiful. It is best to replace all the water pipes within the main pipe. Since the bathroom in the old house is not very large, even if all the water pipes are replaced, the amount of construction will not increase much. On the premise of ensuring the safety of the water supply, the pipeline used for decoration needs to be shortened as much as possible, but it must also be easy to maintain and beautiful.
The dark channel was opened by the waterway. The bathroom in the old house is small. In order to expand the space, it is very necessary to open the waterway to remove the dark pipe. problem. It is best to use the pressure equipment to carry out the pressure test before installing the closed tiles in the water pipe. Generally, the construction team replaces the pressure test with whether the water pipe leaks under normal conditions.
Before installing new pipes, clean the old pipes. The original sewer pipes and floor drains in the old house can not meet the living needs of modern people. Only by adding pipes to move the sewer, before the new pipe is connected to the old pipe, you must check whether the old pipe is smooth. At this time, cleaning it will avoid a lot in the future. trouble. Many modern toilets cannot be directly installed in the original sewage outlet due to problems such as pit distance and drainage method. At this time, the position of the sewage outlet must be moved. If the movement range exceeds 15cm, a toilet shifter is required .
After the waterway renovation is completed, the water pipe is subjected to a pressure test using a pressure machine.
Hidden engineering circuit
The sequence of circuit transformation and construction is generally >> The construction personnel determine the positioning points with the owner according to the design drawings, the protection of the finished products on the construction site, the slotting according to the direction of the line, the slotting according to the direction of the line, the opening of the box, the cleaning of the muck, the electric pipe, the box Fix, wear steel wire, connect various strong and weak wire ends, do not expose to the outside, close the electric groove, and perform acceptance test on the strong and weak electricity
Foundation construction
Basic projects include masonry projects, hydropower installation projects, mud water projects, woodwork projects, paint projects, and water and electricity installation projects. Before carrying out these projects, everyone needs to buy all the auxiliary materials and main materials needed for decoration, so that the decoration project can be smooth get on.
Before the decoration project begins, everyone needs to determine the cabinet and the building materials listed by the foreman. Before the cabinet is installed, the cabinet manufacturer needs to come to the door 3 times: the first time is the preliminary measurement before installing the tiles; the second time is after installing the tiles Two accurate measurements; the last is installation.
Before the decoration starts, the foreman will list some building materials for the decoration owner to buy before the start of construction, such as pipes, wires, waterproof coatings, and conjugate agents; after the decoration starts, other building materials will be purchased according to the decoration construction steps.
