Abstract

The invention provides a construction free formwork and a manufacturing method, belonging to the technical field of building materials, including inner steel wire mesh, outer steel wire mesh, thermal insulation core layer, cement column, outer plastering layer and anchor piece; thermal insulation core layer It is located between the inner steel wire mesh and the outer steel wire mesh; there is a pouring hole in the insulation core layer, the pouring hole is set along the vertical direction and runs through the insulation core layer, and the cement column is located in the pouring hole; the outer plastering layer is located on the outer steel wire The outer side of the net; the anchor piece runs through the insulation core layer and is respectively fixed on the inner steel wire mesh and the outer steel wire mesh. The non-dismantling formwork for buildings provided by the present invention can bear the load through the cement columns in the thermal insulation core layer, thereby improving the load-bearing capacity of the non-dismantling formwork for buildings. At the same time, the cement columns also improve the self-rigidity of the thermal insulation core layer, effectively Prevent distortion and deformation of the insulation core layer.

Description

technical field [0001] The invention belongs to the technical field of building materials, and more specifically relates to a formwork for building without dismantling and a manufacturing method thereof. Background technique [0002] The traditional external wall insulation system requires formwork to be erected on both sides of the wall. After the concrete solidifies, the formwork on both sides is removed. The operation is cumbersome and seriously hinders the construction progress. Therefore, there are long construction periods, poor fire performance, and short service life. , complex construction procedures, high construction costs and other shortcomings. In order to improve the construction efficiency and shorten the construction period, the non-demolition formwork is mostly used at present. The non-demolition formwork has the function of heat preservation and forms an integral structure with the concrete. After the pouring is completed, it does not need to be disassemble...
