Sandwich heat-preserving decorative board with mixed hollow porous fiber reinforced heat-preserving mortar and manufacturing method

Abstract

The invention relates to a sandwich heat-preserving decorative board with mixed hollow porous fiber reinforced heat-preserving mortar and a manufacturing method.A heat-preserving core veneer of the heat-preserving decorative board is a formed veneer and provided with big and round through holes; a hanging part capable of being positioned is arranged at the inner side of a back plate and tightly attached to the back face of the heat-preserving core veneer, and the same big and round through holes are formed in the positions corresponding to the big and round holes in the heat-preserving core veneer; the ends of the hanging part capable of being positioned are provided with small and round holes, square holes and right-angled hooks used for connecting, installing and lapping the heat-preserving decorative board in a positioning mode; fiber grid cloth is arranged at the inner side of a panel and is spaced from the heat-preserving core veneer by 2 mm; the mixed hollow porous fiber reinforced heat-preserving mortar is poured into the periphery of the heat-preserving core veneer through sealed formworks, the panel, the back plate and sealed edges are formed after the mortar is hardened, and bridge-cutoff shear connectors are formed in the big and round holes; the decorative board has the advantages that a good integrated space stress structure is formed through overall pouring of the panel, the back plate, the bridge-cutoff shear connectors and the sealed edges, positioning and splicing are accurate, and the fireproof performance is improved.

Description

technical field [0001] The invention relates to a thermal insulation board for house construction, in particular to a hybrid hollow porous fiber reinforced thermal insulation mortar sandwich thermal insulation decorative panel and a manufacturing method thereof. Background technique [0002] At present, the most widely used thermal insulation technology for building exterior walls in China is "fiber-reinforced polystyrene thermal insulation facing system", that is, the polystyrene foam board EPS (or extruded board XPS) is pasted on the main wall with an adhesive. On the polystyrene board, the glass fiber grid is pasted on the polystyrene board with polymer mortar, and has a certain thickness for waterproofing. In addition, the reason why the wall insulation technology is widely used is that its construction process is relatively simple, the internal and external corners are easy to handle, and the comprehensive cost is low. However, since the self-weight of the exterior dec...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the deficiencies in the background technology, and to provide a hybrid hollow porous fiber reinforced thermal insulation mortar sandwich insulation decorative panel and a manufacturing method; The back panel, broken bridge shear connectors and edge banding are integrally poured to form a well-stressed overall space structure. Even if the core material of the extruded polystyrene board melts, the panel and the finish will not fall off; the panel and the back panel The thickness is small, the board surface is wear-resistant and crack-resistant, the edge is not easy to be damaged, the panel has strong impact resistance, stable weather resistance, and is convenient for construction and finishing treatment; it can be accurately positioned and assembled during assembly; the back board is poured with hybrid hollow porous fiber reinforced thermal insulation mortar, Panels, broken bridge shear connectors and edge banding can achieve the same thermal insulation effect while reducing the thickness of the thermal insulation core material specified in the code, reducing the cost of similar prefabricated thermal insulation decorative panels
