External wall thermal insulation and decoration integrated board with sand pattern decorative external wall surface and its production line

Abstract

The invention relates to an external wall insulation and decoration integrated plate with sand grain decoration for outer wall surface and a production line of the external wall insulation and decoration integrated plate. The plate comprises a middle heat-insulating layer, a rectangular frame and a coagulation layer, wherein the rectangular frame wraps the periphery of the middle heat-insulating layer and is formed by inner and outer layers of fiberglass meshes; the coagulation layer of cement slurry and fiberglass short shred is filled inside and outside the frame; the joint faces of the middle heat-insulating layer and the upper-layer inner surface of the coagulation layer as well as the middle heat-insulating layer and the lower-layer inner surface of the coagulation layer are in convex-concave connection; and sand grain is arranged at the upper-layer outer surface layer of the coagulation layer. The invention also provides the production line of the plate. The plate and the production line of the plate, provided by the invention, have the advantages that: (1) an heat-insulating board is arranged between the coagulation layer of the cement slurry and the fiberglass short shred, the plate can be completed in a precast plant, and exposed heat-insulating materials no longer exist in construction site to ensure that safety production is guaranteed, and potential safety hazard does not exist; and (2) external wall insulation and decoration surface layers are simultaneously completed to ensure that the working procedure and the working time are saved, the construction period and the engineering quantity are decreased, a qualitative leap is realized, and a remarkable economic benefits are obtained.

Description

technical field [0001] The invention relates to a building component, in particular to an exterior wall thermal insulation and decoration integrated plate with a sand grain decorative exterior wall surface and a production line thereof. Background technique [0002] At present, building energy efficiency is booming in the world, and building energy efficiency has become a common choice of the global building industry after deliberation. The first thing to talk about in building energy conservation is the thermal insulation of building exterior walls, which has become a mandatory clause of the Ministry of Construction. At this stage, the construction process of external wall insulation is roughly as follows: after the formwork of the external wall of the building is removed, apply adhesive mortar on the external wall, paste insulation boards, hang nets, apply anti-cracking mortar, and finally make a finishing layer. Among them, the external wall insulation boards currently u...

AI Technical Summary

Problems solved by technology

The shortcomings of EPS boards are: first, the strength is not high, the load-bearing capacity is low, and it needs to be strengthened when veneering bricks;

If the curing time is insufficient, the quality of the board cannot be guaranteed, and the board will shrink after construction, causing the system to crack

The disadvantages of the XPS board are: First, it is difficult to ensure the flatness of the XPS board, and the anti-cracking mortar on the outside is difficult to cover the board seams, especially in the arc section, so it is not suitable for walls with paint as the exterior finish The second is that the strength of the XPS board itself is high, but the board is brittle and not easy to bend. If there is stress concentration on the board, the board will be damaged and cracked; the third is that the air permeability is poor and it is almost airtight. If the board The temperature difference on both sides is large, and the humidity is high and it is easy to condense; the fourth is that its structure has poor flexibility, which is affected by changes in temperature and humidity and deforms and bulges, causing the insulation layer to fall off

To sum up, the current situation of on-site construction for thermal insulation and decoration of building exterior walls is that there are many and complicated procedures, and the defects of these thermal insulation materials are exposed, resulting in poor construction safety, poor fire performance of exposed thermal insulation materials, and serious damage. Poor safety hazards, poor quality after construction, poor building appearance, easy cracking and hollowing of the wall surface, and defects such as peeling of the paint surface
