Prefabricated light partition board

Abstract

The invention provides a prefabricated light partition board. The prefabricated light partition board is characterized in that the partition board (6) comprises a framework and a straw coal ash and fine aggregate concrete layer (7) which is poured on the framework; and the framework is composed of a corrugated foam insulation plate (5) which is located in the middle and punched steel plates (1) which are fixed to the two sides of the corrugated foam insulation plate (5) through bolts (3). The thickness of each punched steel plate (1) is 0.5-2 mm, the diameters of holes in the punched steel plates (1) are 10-15 mm, and the distance between the centers of every two adjacent holes is 20-40 mm. According to the prefabricated light partition board, the punched steel plates which have certain rigidity and extremely high strength are adopted, so that the rigidity and strength of the prefabricated light partition board in the manufacturing process are guaranteed, the bearing capacity of the partition board under a load is improved, expansion of cracks in the wall forming process is limited, and generation and development of cracks in the using process are restrained.

Description

technical field [0001] The invention relates to a lightweight non-load-bearing wallboard for construction, which can be used as a filling wallboard or a partition wallboard. Background technique [0002] my country's existing representative filling wall materials include concrete hollow blocks, aerated concrete slabs, etc., but there are still some problems in the wall materials themselves and their application and promotion. The hollow block wall is made of small hollow blocks through different construction techniques. The wall has the advantages of saving soil and energy, low cost, and convenient and quick construction. However, because the block is relatively heavy, it is prone to shrinkage, deformation, damage, and inconvenient processing; the workload of masonry is large, and the demand for tensioned steel bars is large, which is not convenient for the development of industrialization of construction; improper connection processing, the wall is prone to cracking, cracks...

AI Technical Summary

Problems solved by technology

However, there are also low strength, poor impact resistance, loose board quality, and easy damage during handling and hoisting; large drying shrinkage, prone to drying shrinkage cracks, affecting appearance quality and strength; boards are easy to absorb water and moisture, and improper stacking can easily cause deflection , cracking and other losses; the bond with the mortar is not firm, and there are shortcomings such as easy falling off and cracking of the wall plaster layer

[0004] There are also partition boards made of cold-formed thin-walled steel and external sprayed cement fiber concrete, which are heavy and relatively expensive, and the bond between the steel keel and concrete is weak; there are also organic boards (benzene boards), etc., Partition wall boards made of cement fiber boards, but there are technical problems of how to stick and compress the three-layer boards. Under load, cracks between layers are prone to occur, and temperature changes cause differences in deformation between different materials, resulting in cracks. The problem is not easy to solve
