20 18 decoration wall demolition taboo wall must not be demolished like this.

Demolishing the wall of a house is a complicated matter. In the process of house renovation and demolition, there are many places to pay attention to. Some places can be moved, and some places cannot be changed. Once changes are made, security problems may arise. Then, what taboos should owners know when decorating and demolishing houses? What are the wrong demonstrations when decorating and tearing down the wall? Let's take a look at Bian Xiao.

A, decorate metope taboo

1, load-bearing wall

What kind of wall is a load-bearing wall? Generally speaking, brick-concrete buildings, as long as they are prefabricated walls, are not allowed to be demolished or opened; Brick walls over 24cm are load-bearing walls and cannot be removed. Most of the "empty sound" walls are non-bearing walls and can be demolished and changed.

2. Lightweight wall

In addition to load-bearing walls, lightweight walls are not allowed to be demolished at will. Some lightweight walls also bear part of the weight of the house. For example, the light wall under the beam cannot be demolished because it also bears part of the weight of the house. If it is demolished, it will destroy the structure of the house. Lightweight walls and hollow slabs that are completely used as partition walls can be removed. This kind of wall does not bear any pressure at all, and its value of existence is to separate the space. Demolition will not have any impact on the building structure.

3. Low wall beside the balcony

Generally speaking, there is a door and a window between the room and the balcony. These doors or windows can be removed and modified, but the low wall under the window cannot be moved. The door frame of the "three-proof" or "five-proof" door is embedded in concrete. If they are removed, it will destroy the building structure and reduce the safety factor. But also destroyed the building structure at the entrance and increased the difficulty of reinstalling new doors.

Second, the typical error demonstration of wall demolition

1. Remove the wall between the room and balcony.

The wall between balcony and room refers to the wall under the window and the wall between windows, which mainly bears vertical load and horizontal seismic force. If these walls are demolished, a big doorway will be formed between the balcony and the room, which will change the original working state and mechanical properties of the structure.

2. Open doors and windows on the load-bearing wall to make the wall thinner.

Load-bearing wall refers to the wall where floor slab, joist, girder, roof truss or roof panel are placed. It bears the live load and static load from the upper floors, beams, roof trusses and other layers, and also bears the self-weight of the upper wall, and transfers these loads to the lower wall until the foundation. Demolishing the bearing wall, or opening doors and windows on the bearing wall or thinning the bearing wall will not only directly destroy and weaken the bearing capacity of the bearing wall, but also destroy the integrity and seismic capacity of the house.

The above is the taboo about 20 18 decoration and wall demolition. I hope I can help you!
