Description

A Fireproof Shear Wall Building Structure

technical field

The utility model relates to a building structure, in particular to a soundproof and fireproof wall structure, which belongs to the technical field of building structure equipment.

Background technique

Shear walls are also called wind-resistant walls, seismic walls, and structural walls. Walls in houses or structures that mainly bear horizontal loads and vertical loads {gravity} caused by wind loads or earthquakes. To prevent structural shear failure, it is divided into plane shear wall and cylinder shear wall. Planar shear walls are used in reinforced concrete frame structures, raised slab structures, and beamless floor systems. In order to increase the rigidity, strength and collapse resistance of the structure, reinforced concrete shear walls can be cast-in-place or prefabricated in some parts. Walls can be divided into load-bearing walls and shear walls according to their stress characteristics. The former mainly bears vertical loads, such as masonry walls; the latter mainly bears horizontal loads. In the seismic fortification area, the horizontal load is mainly generated by the horizontal earthquake action, so the shear wall is sometimes called the seismic wall.

At present, the existing building structure does not have good fire performance and cannot withstand fire well. At the same time, the vertical and horizontal seismic performance of the existing building structure cannot be well balanced. Therefore, we propose a fireproof shear force Wall building structure.

As a preferred technical solution of the present invention, an attachment chamber is provided on one side of the steel bar, and a pressure-expanding substance is provided in the attachment chamber.

As a preferred technical solution of the utility model, one side of the two groups of flame-retardant layers is coated with a layer of waterproof material.

The beneficial effects achieved by the utility model are: a fire-proof shear wall building structure, since the inner and outer sides are equipped with flame-retardant layers, it can well prevent the fire from spreading outside and inside the house, causing fires in other households Dangerous, because the two sets of load-bearing walls can well support the entire wall and enhance the earthquake resistance of the entire wall, because multiple groups of steel bars intersect with each other and there are reinforcing ribs installed between the joints, which greatly enhances the The vertical and lateral stability of the entire wall is due to the pressure expansion substance in the cavity attached to one side of the steel bar. When the wall collapses, the steel bar breaks due to the pressure and releases the pressure expansion material, which can prop up the wall for a space , which is conducive to protecting people's personal safety.
