Composite foamed cement board

Abstract

The invention discloses a composite foaming cement board. The composite foaming cement board comprises a foaming board main body, butt joint grooves are formed in the left side and the right side of the foaming board main body, and flow guide grooves are formed in the upper side and the lower side of the foaming board main body; a first connecting part is arranged in the butt joint groove in the left side of the foaming board main body, and a second connecting part is arranged in the butt joint groove in the right side of the foaming board main body; and during laying, the first connecting part is arranged below the second connecting part, the first connecting part and the second connecting part clamp and fix the foam board main body to be laid up and down, and multiple foam board main bodies are fixedly connected end to end through the first connecting parts and the second connecting parts. According to the composite foaming cement board, when the foam board main body is laid on the wall surface, the fixing effect between the foam board main body and the wall surface can be improved through the structure, meanwhile, for an uneven area of the wall surface, hexagonal holes can be inserted into an external tool to rotate a threaded rod to level the wall surface so that the laid foam board main body can be horizontal and consistent, and the misplaced laying probability is reduced.

Description

technical field [0001] The invention relates to the technical field of foamed cement boards, in particular to a composite foamed cement board. Background technique [0002] With the aggravation of the global energy crisis, the vigorous promotion of my country's energy-saving and emission-reduction policies, and the in-depth development of building energy-saving work, the external wall insulation industry has developed rapidly. Due to the flammability of the material itself, thermal insulation boards are widely used. Once a fire accident occurs, it will seriously endanger people's lives and property safety. Composite foamed cement board is a new type of inorganic external wall insulation material developed in recent years. It is environmentally friendly, A-class fireproof, easy to obtain raw materials, high cost performance, the same material as the matrix, and good compatibility with ordinary concrete. , with the same life as the building, and the external dimensions can be ...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventors found that at least the following problems in the prior art have not been solved: 1. The traditional composite foamed cement boards are cut into plates of specified sizes according to construction requirements when in use, and then transported to the construction site with concrete As an adhesive, it is laid on the surface of the wall to form a fireproof and thermal insulation wall. However, due to the installation angle and the temperature of the concrete added to the gap between two adjacent panels during the laying process, there is a slight deviation in the upper and lower dimensions, which is not easy to find in time. , with the progress of the laying progress, the dislocation phenomenon is obvious, and the overall construction progress will not be completed at this time. This process requires experienced workers to operate to reduce the occurrence of such phenomena, which is not convenient for novice workers to operate and use. Continuous superimposed laying, the weight of the bottom board is limited, it is easy to cause the bottom board to break and fall off, thus affecting the use; 2. The traditional composite foam cement board has the following disadvantages. Time is eroded by rainwater and sun exposure, it is easy to pulverize and break, and the heat absorption rate is high. Although this kind of product has certain thermal insulation performance, if it is used in a high temperature environment, the heat absorption rate is relatively high, which is difficult to meet the needs of users.
