Many people are now renovating and want to get the room connected to readjust the interior layout. The only thing to do to get through the room is to dismantle the wall, but not any wall can be dismantled. If the wall that cannot be dismantled is dismantled at will, the stability and seismic resistance of the building will be greatly reduced, causing irreparable seriousness as a result of. All must pay attention to some precautions in demolition.
One and four strokes learn to distinguish load-bearing walls
The most critical point of the wall reconstruction is that the load-bearing wall cannot move casually. How to distinguish which are the load-bearing walls?
1. See the floor plan information
In the house plan, the black walls marked on the engineering drawings are load-bearing walls, and the white walls are non-load-bearing walls. These walls can be demolished and demolished, and will not affect the building construction.
2. Look at the structure of the house
Generally speaking, all walls of brick-concrete structures are load-bearing walls. The outer wall of the house with a frame structure is a load-bearing wall, and the inner wall is generally not a load-bearing wall.
3. See the grade of the house
Generally low-rise residential buildings, bungalows and villas are brick-concrete structures, and the basic faces are load-bearing walls. The high-rise elevator building and the foreign building are both of frame structure.
4. See the thickness of the wall
Non-load bearing walls are relatively thin, generally around 10 cm thick. It is a light body wall with a crisp big echo, and the load-bearing wall is generally more than 240MM thick. There should not be too much sound when knocked.
Second, look at the common misunderstandings of load-bearing wall reconstruction
Many people are concerned about whether the load-bearing wall can be changed. Let us understand the misunderstandings about the renovation of the decoration wall.
Myth 1: The structure of the load-bearing wall can be changed at will
The renovation of the wall in the decoration cannot damage the load-bearing wall. Because damage to the load-bearing wall is to destroy the seismic resistance of the building. According to the law, damage to the load-bearing wall must not only be restored, but it can also be fined up to 200,000. Therefore, the load-bearing wall is immobile.
Myth 2: The load-bearing wall can be removed
Generally speaking, the load-bearing wall cannot be removed. If you remove the load-bearing wall, your neighbor has the right to sue and demand restoration. For safety, don't dismantle the load-bearing wall. At the same time, the load-bearing wall is scientifically calculated. If holes are drilled and decorated on the load-bearing wall, it will affect the stability of the foundation.
Misunderstanding 3: the load-bearing wall can open the door
Aside from the legal constraints, the door can be opened purely from a technical point of view, but this demolition construction operation and subsequent reinforcement plan must be completed by a professional construction company. Construction must be embedded in channel steel, and the door should not be too wide, it is recommended not to knock the load-bearing wall.
Myth # 4: Non-load bearing walls can be removed
The traditional concept is that the load-bearing walls in the house cannot be removed, and non-bearing walls can be removed. In fact, this is a big mistake. In fact, not all non-bearing walls can be demolished at will. Non-bearing walls also have two important roles. One is the supporting effect of the wall's own weight, and the other is its anti-seismic effect. Therefore, as far as a family is concerned, it is not a big problem to demolish the non-load-bearing wall or make a hole in the wall, but if the residents of the whole building randomly demolish the non-bearing wall, it will greatly reduce the seismic resistance of the building.
3. Precautions for dismantling and rebuilding the house wall
Demolition and modification of house walls is mainly about safety. Not only must we distinguish whether the dismantled wall is a load-bearing wall, but we must make adequate plans when transforming a safe non-bearing wall.
1. Note that only non-bearing walls can be dismantled or modified
Before renovation and demolition, we must understand which walls can be dismantled and which can not be dismantled, otherwise the consequences will be unimaginable. The only walls that can be dismantled are non-load-bearing walls. Non-load-bearing walls are generally thin and roughly 10 cm thick. Generally, these walls are indicated on the floor plan.
2. Pay attention to reconstruct the circuit pipeline
Before dismantling, the direction of the circuit transformation must also be considered in detail. Generally, there are circuit pipelines in the wall, so be careful not to break the circuit due to brutal construction. After all, the transformation of the circuit is a very moist part of the project cost. If you do n’t want the decoration company to make too much money for you, you must plan it well.
3. Add new walls and choose materials according to the situation
High-rise buildings generally adopt a frame structure, that is, the outer wall is load-bearing, and the inner wall is generally a light-body structure wall. The inner wall only serves as a partition and has little support for the load-bearing. When you add a new wall, you generally use the same light-weight wall as the original cement board wall or gypsum board. You can also choose materials with better sound insulation or cost-effective according to your own requirements.
4. Looking for professional decoration company Suzhou Decoration Net
Many people do not know what the structure of their house is. If you want to demolish the wall, you must find an experienced decoration company to take a look at it, understand the structure of the wall and make a decision to avoid the danger caused by random demolishing. At the same time, before construction, it must be reported to the property management department for record, and construction can only be carried out after approval.
