Dry-process precast floorboard and manufacturing method therefor

Abstract

The invention relates to a dry-process precast floorboard. The floorboard comprises an aluminum profile frame, wherein a cement-fiber board layer, a lower polyurethane adhesive layer, an aluminum honeycomb layer, an upper polyurethane adhesive layer and a face material layer are sequentially distributed in the aluminum profile frame through hot-press laminated forming, indent waterproof adhesive tape mounting grooves are formed in middle parts of outer peripheries of the aluminum profile frame, a waterproof adhesive tape is mounted in the waterproof adhesive tape mounting groove of each side of the aluminum profile frame, two waterproof adhesive tapes mounted in the waterproof adhesive tape mounting grooves of two adjacent sides of the aluminum profile frame are staggered up and down, andthe floorboard is supported on a floor by adopting a height-adjustable threaded supporting seat. The dry-process precast floorboard has the beneficial effects that on one hand, the manufactured floorboard is light in weight and superior in flexural resistance; on the other hand, a face material is directly laminated on the upper surface of the floorboard, the sticking of the face material on siteby using cement mortar is avoided, the workload of site mounting is reduced, and the problem of long construction cycle is solved; and the problem of leakage between adjacent floorboards and between the floorboards and walls is solved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a dry assembled floor and a manufacturing method thereof. Background technique [0002] Traditional floor decoration usually adopts wet method, and the cement mortar concrete is leveled and then pasted with decorative surface materials. In recent years, various quick-installation systems have been widely used in interior decoration and floor decoration projects, such as installing keels on the ground, and veneering materials after wet method. In the actual application process, the construction process is complicated, the labor cost is high, and the ground is prone to appear. Cavities, poor waterproofing, etc., once a problem occurs, it needs to be destructively removed, making maintenance extremely difficult. [0003] In recent years, the application fields of composite materials have become more and more extensive, and there are large-scale applications in the field...

AI Technical Summary

Problems solved by technology

Although this method solves the problem of using cement mortar for concrete leveling and long installation period, it has another defect: the ground is hollow and the waterproof performance is poor

The ground is hollow because the surrounding of the keel is empty, and only the thin decorative surface layer is connected as a whole, and it will make a loud noise when stepped on, and the texture is not good; in addition, the water resistance of the entire ground is only depended on the surface material Adhesive layer, greatly increasing the risk of water leakage
