What are the precautions for home renovation demolition? What are the pitfalls?

Precautions: the demolition and reconstruction of the main body of the building to ensure safety, the renewal of the main body of the building often appears in the case of the overall planning of the indoor space again, the demolition and reconstruction of the main body of the building needs to ensure safe construction, many dilapidated houses generally belong to the wall is a load-bearing beam, this wall is definitely not allowed to be updated. Do not change the sewer pipe network, the demolition and modification of the sewer pipe network is also the decoration of second-hand houses is common, in the case of demolition and reform, it should be noted that the sewer pipeline of the toilet should not change the position, because the sewage pipe for the ups and downs and the pipeline angle level of the standard is higher, if the dismantling and modification of the pipeline has a slight error, it will directly affect the actual effect of drainage in the future.

Don't dismantle the counterweight wall, the counterweight wall refers to the wall of the design distance between the living balcony and the interior space, there is generally a door and a window, the window and door can be demolished, but the wall can not be dismantled casually, because the "counterweight wall" plays the main function of provoking the living balcony, especially the floating living balcony, it is necessary to assist this "counterweight wall".

Sanitary ware disassembly, brick knocking is an important construction of sanitary ware demolition and reconstruction, the demolition process must pay attention to the old ground waterproofing generally do not do off, after knocking bricks, on the original ground waterproof, and then a thin layer of moisture-proof, in order to enhance the moisture-proof work ability of sanitary ware. When knocking on the floor tiles around the electrical socket and the collar, do so gradually, and be careful to feel the direction of the cable and water mains to prevent damage to the cable and water main.

Pavement demolition, pavement demolition and modification of the key must be to smash the concrete foundation cushion, only smash the ground tiles is not allowed; The quality of the disassembly is important, and it is important to ensure that the dismantling is thorough and the road surface is cleaned and tidy; If it is a paved road with underfloor heating, beware of smashing the underfloor heating pipes; In the case of smashing floor tiles in the kitchen and bathroom, the anti-odor floor drain and drain must be plugged to avoid dirt falling into the pipe and causing blockage.

Attention should be paid to the construction of power circuit engineering, the circuit principle should be multi-channel, and ensure that the air conditioner, dining room kitchen, toilet, large living room, bedroom, computer and high-power electrical appliances are separately routed; The power socket and power switch are separated, and the leakage circuit breaker should be applied separately for each control loop except for general lighting and wall-mounted air conditioning; Strong and weak separation, speakers, mobile phones, multi-system, optical fiber broadband and other strong current line design schemes should be effective standards.

We must pay attention to the waterproof problem, we must deal with the base layer of the ground, the doors and windows must be protected, the lines must be connected, and the walls must be dealt with; The wall is deformed, the later line repair is very troublesome, the doors and windows are not dealt with well, it will be very ugly, and the floor may produce hollowing.

Before demolition, be sure to remove your own intact items, and be careful not to move the load-bearing walls during the demolition process, not to knock down the walls in the room at will, and not to change the layout of the house. In the process of home renovation and demolition, some construction units will ask you to add money, and you need to make a correct judgment at this time.

Nowadays, in order to create the most comfortable living conditions, it is essential to decorate the home according to the way they like. We want to reinvent that dissatisfaction, and I think a lot of owners are doing that. But the demolition project is not as simple as you think, and there is still a lot to pay attention to.

ThatDecoration and decoration demolitionWhat is there to pay attention to? Please check out the following introduction.

Decoration and decoration demolitionShould the door be dismantled first or later?

Generally in principle, it is the last one, but if it is a two-piece door, you can remove the wooden door first or remove the door that is not closed first. This is to prevent accidents caused by thieves entering during construction or by people who are not working during construction.

Decoration and decoration demolitionCan the original tube be replaced?

In principle, different migrations can be carried out depending on regional changes. However, in the drainage section, it is treated without affecting the drainage, or without affecting the power position of the main switch.

Decoration and decoration demolitionWhat should I pay attention to when dismantling hydropower?

Decoration and decoration demolitionThe first thing to pay attention to is the problem of water cutting. Water can be divided into general domestic water and fire water. When the water is cut off, the fire water cannot be cut off.

You should pay attention to the coordination of the main switch as well as the units related to the structure, especially if it is not handled properly. The water flows down the stairs, causing a family dispute. When it comes to power outages, when power is cut off in your home, remember to equip temporary energy sources with safety guards to make work easier.

Fire-fighting equipment, such as emergency lighting equipment or induction systems, such as thermal sensors, must be protected. Be careful when removing them and remember to restore them. The acceptance of the quality of hidden works is very important, it is the intrinsic quality of all residential renovations and cannot be ignored.

If the owner does not ask a professional to prove it, he can verify it according to the following requirements and leave a written record if necessary.

Some of the explanations above are what we are aboutDecoration and decoration demolitionSome introductions, I think friends can use. For friends who are ready to redecorate, it can be used as a reference content.

There are always places in the house that seem to be impossible to move, and occasionally we may tear it down, but we don't know that our negligence has buried hidden dangers in home life. Load-bearing walls cannot be demolished, we all know them, but non-load-bearing walls can be demolished at will? Experts say that whether the non-load-bearing wall can be removed depends on the situation.

Some lightweight wall structure walls, such as light steel keel, gypsum board wall or cement board lightweight wall, this kind of spacing wall demolition is not a risk and can be removed. For the half-brick wall of the bathroom, if the support beam that supports the wall is programmed during the construction of the floor slab, it can be removed, otherwise it cannot be disassembled. Although a non-load-bearing wall is a non-essential load-bearing component of a house, it is an extremely important support for a load-bearing wall.

<>For some families, there is not much doubt about removing the non-load-bearing wall, but if the residents of the entire building dismantle and replace the non-load-bearing wall body at will, it will greatly reduce the seismic resistance of the main body of the building. Since the balcony is not supported by beams and columns, the load that can be borne is weak, so the light weight data should be selected for decoration as much as possible. Usually the wall between the room and the balcony has a door and a window.

These doors and windows can be removed and changed, but the walls under the windows cannot be moved. This section of the wall is called the "counterweight wall", and it acts as a balconies.

Tearing and replacing this wall will reduce the load-bearing capacity of the balcony, causing the balcony to collapse. In the renovation, what places cannot be demolished at will? If the structure of a house is compared to the body of an adult, then the steel bars on the walls are the bones and muscles of the person.

If the reinforcement is destroyed during pipe laying, the bearing capacity of the walls and floor slabs will be affected. Once this happens**, these walls and floors can easily collapse or break. There is a waterproof layer underneath these places, and if it is damaged, the downstairs will become a "water curtain hole", so when replacing the floor material, you must be careful not to damage the waterproof layer.

If it is damaged after rebuilding, it must do a "24-hour water seepage test", that is, fill the kitchen or bathroom with water, and if the leakage is qualified after 24 hours. According to the investigation, in order to facilitate the decoration, some construction teams often appear on the wall with transverse slotted wiring, so as to minimize the length of the wiring pipe and save money, but the wall structure is damaged, forming a serious safety hazard. Load-bearing walls with transverse grooves, such as glass cut by diamonds, are prone to cracking in intense**.

According to experts, the lateral slotting of the light body wall does not exceed 50 cm in principle; Transverse grooves are not allowed on load-bearing walls; The transverse grooves of the internal insulation wall should not exceed 100 cm.

1: Load-bearing wall. The load-bearing wall must not be demolished, if the load-bearing wall is removed, it will not only affect the family, but also endanger the safety of the whole building, and it is serious to bear legal responsibility.

2: Beams and columns. The beams and columns actually support the upper floor of the building, and if they are removed, it will cause safety hazards, and the load-bearing wall is the same reason.

3: Balcony half wall. There will be a half wall between the living room and the balcony of some units, which is the counterweight wall of the balcony, and if it is removed, it will cause the danger of the balcony falling.

Meters cannot be removed, pipes cannot be removed, wires cannot be removed, load-bearing walls cannot be removed, and walls within the specified range cannot be removed. The reason is that if it is demolished, then there will be compensation accordingly, and all your deposits will be deducted, you will be asked to pay compensation, and you will be asked to compensate for the building, which will violate the safety of the building.

Load-bearing walls, balcony half walls, beams and columns, bay windows, strong and weak electric boxes, these places cannot be removed; If the load-bearing wall is removed, it will affect the safety of the whole building, and it will make your house have a lot of safety hazards.

In the process of home decoration and demolition, there are many things that need to be paid attention to, and if you are a little sloppy, it is easy to produce some irreparable problems, resulting in potential safety hazards. So, let me share with you the demolition of professional house demolition projects, as well as the precautions for home renovation demolition.

1. Demolition of professional houses for family demolition and demolition of professional houses.

What are the home decoration demolition projects: reinforced concrete wall cutting and demolition, concrete building girder demolition, door face room demolition, indoor floor tile demolition, floor demolition, tile demolition, partition wall demolition, false wall demolition, ceiling demolition, bathroom demolition, window sill demolition, door and window demolition, brick wall demolition, wall, support beam, etc. demolition.

2. Precautions for home decoration and demolition.

1. The ground should be waterproof when it bottoms out.

The bottom of the ground must be waterproof first, otherwise it is very likely that the water will seep downstairs during the construction process to avoid unnecessary trouble to yourself.

2. The toilet bowl is finally dismantled.

If there is no impact on cleaning and drainage, the toilet can be dismantled last, so that workers can also use it during on-site construction, which is more convenient.

3. Pay attention to foreign objects falling into the wall surface of the pipeline when dismantling.

When the wall is removed, do not let the cement or broken bricks fall into the pipe, under the influence of gravity, the falling objects can easily damage the pipeline, so it will be a big trouble.

4. Demolition should be bottomed out and pay attention to nails.

When removing the baseboard, the nails on the ground must be pulled out, and if it is a stone wall, it must be hit to the bottom.

5. The perforated wall surface moves to the beam and structure.

If the range hood, exhaust fan and other pipelines at home need to be perforated, the beam cannot be pierced, and the entire structural layer cannot be moved.

6. Keep the appearance beautiful and safe.

It is necessary to take the best protective measures, the construction appearance should be kept in line with the local environment, to ensure safety and beauty, special attention should be paid to the aisle area, and it is best not to have destructive handling.

Article summary: The above is the relevant content of the home demolition professional house demolition project demolition project demolition project that I shared with you, as well as the precautions for home renovation and demolition. There are many problems to pay attention to in the interior decoration and renovation, otherwise it is easy to damage some facilities.

1. When the wall is demolished, it is necessary to ensure safety, the house decoration will often transform the existing pattern of the slag in front of the car, and the construction safety must be ensured when the wall is removed.

2. The transformation of the sewer pipe network is also very common in the decoration and demolition, and it is necessary to pay attention to the sewer pipeline of the toilet when dismantling and renovating the position as much as possible, because the sewage pipeline has higher requirements for the drop and pipeline angle, and if the pipeline after the demolition and modification has a slight deviation, it will affect the sewage effect in the later stage.

3. The circuit design in the dismantling should be multi-channel, so that the kitchen, bathroom, living room, bedroom, computer and high-power electrical appliances are wired separately; Sockets and switches are separated, and leakage protectors should be used independently in each circuit except for general lighting and wall-mounted air conditioners; Strong and weak are separated, and the design of weak current lines such as audio, multi-power, and broadband networks is reasonable and standardized.

4. In the transformation of the waterway, it is necessary to think about the use of gas or electric water heaters in advance, so as to avoid temporary replacement of the type of hot water repentance, which will lead to repeated transformation of the waterway. In addition to leaving the water outlet for the wash basin, horse closed bucket, washing machine, etc., it is best to take one out, and it is very convenient to receive water and mop the floor in the future.

5. Demolition of the bathroom demolition brick knocking is the key construction of the bathroom demolition and reconstruction, the demolition process needs to pay attention to the old waterproof layer is generally not knocked off, after knocking the brick, on the original waterproof layer, and then a thin layer of waterproofing, in order to improve the waterproof ability of the bathroom. When knocking on tiles near sockets and faucets, knock slowly, carefully finding the direction of the wires and water pipes to prevent damage to the wires and water pipes.

6. The ground demolition and modification must mainly smash the cement cushion, and it is not possible to only smash the ground bricks; The quality of house renovation and demolition is the key, and it must be ensured that the demolition is complete and the ground is cleaned; If the floor is covered with underfloor heating, carefully smash the underfloor heating pipes; When smashing the floor tiles in the kitchen and bathroom, you need to plug the floor drain and drain to prevent debris from falling into the pipe and causing blockage.
