Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a cast-in-place foam concrete light steel keel composite wall structure. Background Art

[0002] In the existing construction technology, the wall structure usually adopts a variety of materials and construction methods. Among them, the building wall constructed by light steel foam concrete has the advantages of good thermal insulation performance, light weight and strong sound insulation. In the publication number: CN204531076U, a light steel lattice cast-in-place foam concrete composite wall is provided. The composite wall formed by pouring foam concrete on site with light steel main keel as the skeleton and two-sided composite fiber reinforced calcium silicate board as the non-disassembly template is formed by using special equipment to cast the foam concrete on site. The construction is fast and convenient, and the construction cost is greatly reduced. The problem of complex wall structure and slow construction speed of the traditional system is solved. At the same time, the fiber reinforced calcium silicate board is compositely coated with alkali-resistant mesh gypsum board, which greatly improves the mechanical strength and crack resistance of the wall. Since the fiber reinforced calcium silicate board is directly set on both sides of the light steel main keel, it needs to be fixed with screws. During the installation process, it is necessary to draw lines on the surface of the fiber reinforced calcium silicate board to ensure that the screws can be fixed on the light steel main keel. At the same time, it is necessary to ensure that there are enough screws to avoid detachment during the pouring process. Therefore, a lot of time is consumed in the process of installing the fiber reinforced calcium silicate board, affecting the overall construction progress. Utility Model Content
