Description

Wall structural unit for building

Technical field

The present invention relates to the field of building construction technology, and in particular to a wall structural unit for a building.

Background technique

With the development of the construction industry, people have gradually put forward higher requirements for the performance of building materials. In recent years, people's awareness of safety has been continuously improved. In addition to considering the stability of buildings, more consideration is given to building stability. It also takes into account the fire performance, seismic performance, thermal insulation properties and radiation resistance of the building.

The thermal insulation materials used in the wall structure of the existing structure of the prior art are mostly fire-rated grade B materials, which cannot meet the requirements of high level of building fire protection requirements, especially in the field of high-rise and super high-rise buildings. At present, there are a small number of walls using thermal insulation materials of Class A fire protection, but such wall construction and assembly processes cannot meet the requirements of long-life and durable walls, and are not suitable for practical applications.

Summary of the invention

The object of the present invention is to overcome the above-mentioned drawbacks of the prior art, and to provide a fireproof material, earthquake resistance and crack resistance which can be used for buildings from the inside to the outside, and has good thermal insulation effect and radiation resistance.

According to an aspect of the present invention, a wall structural unit for a building is provided, comprising a mortar layer, the mortar layer facing the interior of the building is adjacent to the Class A fireproof material layer, and the inside of the Class A fireproof material layer is adjacent to the barrier layer. In the mortar layer, a bottom net and a top net are sequentially arranged in a direction toward the outside of the building, wherein the bottom net is a sawtooth first metal grille net having a flat valley bottom and a flat valley peak, and the length of the flat valley bottom and the flat valley peak Equally, the top net is a planar second metal grille net, the top net is completely covered on the bottom net, and fixed by the second fastening element, the first fastening element passes through the grid hole of the flat bottom, the A-level fireproof The U-shaped keel in the material layer and the isolation layer is fixed in the U-shaped keel.

The essential points of the wall structure unit of the present invention are: first, the mortar layer is connected with the layer A fireproof material layer, and the layer A fireproof material layer is connected with the isolation layer to improve the fireproof performance of the wall, so that the wall body satisfies all The use of Class A fire protection materials, and second, the bottom mesh in the mortar layer is in contact with the top mesh to form a Faraday cage that keeps the interior of the building away from radiation, for example, from high voltage transformers, communication systems and radioactive sources. The radiated radiation increases the ability of the wall to resist radiation, high voltage electricity or lightning; on the other hand, the combination of the bottom net and the top net eliminates the internal stress in a stable manner, so that the wall is subjected to a balanced force. The flat valley peaks and the flat valley bottoms with equal lengths ensure uniform distribution of pressure on the metal grid, avoid wall cracks, better adapt to the length between the walls, and can randomly distribute an integer number of wall structures. Finally, the U-shaped keel is not only used to accommodate the insulation layer, but also to fix the internal covering, and thus they form a unified fixing system. Thus the wall structural unit can be provided with an already pre-installed inner covering so that no on-site assembly is required in this respect. In the simplest case, the inner covering can be a cement fiberboard or a gypsum board followed by a decorative finish. At the same time, the first fastening element passes through the mesh hole of the bottom valley of the bottom net, the layer A fireproof material layer and the U-shaped keel in the insulation layer are fixed in the U-shaped keel, that is, the mortar layer is realized by the fastening component, A The physical combination of the layer of fireproof material, the barrier layer, and the U-shaped keel does not require the use of an adhesive, making the assembly of the wall simple.
