According to the multi-rib reinforced dual-cavity composite heat preservation building block, the structure is reasonable, the heat preservation effect is remarkable, and the energy saving effect is very obvious, so that good economic and social benefits can be produced.

Description

Multi-reinforced double-cavity composite thermal insulation block

technical field

The utility model relates to the field of construction and thermal insulation materials, in particular to a multi-reinforced double-cavity composite thermal insulation block for construction. the

Background technique

The wall made of thermal insulation blocks and mortar can be used as the load-bearing wall and maintenance wall of industrial and civil buildings. The current main structure of this thermal insulation block is composed of a concrete shell and foamed concrete or foam slurry filled in the cavity of the concrete shell. It has good heat preservation and heat insulation effects and good fire prevention, durability, sound insulation, compression resistance, waste utilization and other properties, but most of them have problems such as too high heat transfer coefficient. the

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned shortcomings, introduce the new through the old, and design a multi-reinforced double-cavity composite thermal insulation block. The block has the advantages of previous similar composite thermal insulation blocks, and at the same time, the end faces at both ends of the concrete shell extend the length of the cold and thermal bridge, so the thermal insulation and heat insulation effects of the block are better. the

The utility model adopts the following technical solutions

1. A multi-reinforced double-cavity composite thermal insulation block, which is composed of a hollow concrete shell (1) and an inorganic thermal insulation foam (3) filled in the cavity (2) of the concrete shell. There is a groove (4) extending the length of the cold and heat bridge in the middle, and the connecting rib (5) connects the two parts of the block into one. the

2. The grooves (4) extending the length of the cold and heat bridges at the middle of the two ends of the concrete shell are U-shaped grooves, V-shaped grooves, semicircular grooves, elliptical grooves, and square grooves. the

The beneficial effect of the utility model is that the structure of the multi-reinforced double-cavity composite thermal insulation block is reasonable, and it is an improvement and enhancement of the previous similar composite thermal insulation block. The end faces at both ends of the concrete shell extend the length of the cold and heat bridge, so the heat preservation and heat insulation effects of the block are better, and the energy saving effect is very obvious. After popularization and use, it will have good economic and social benefits. the

Detailed ways

Example 1

Multi-reinforced double-cavity composite thermal insulation block, firstly make a hollow concrete shell (1), the hollow concrete shell (1) has a cavity (2) in the concrete shell, and a cavity in the concrete shell (2) Inorganic thermal insulation foam (3) filled with phosphogypsum or desulfurized gypsum or cement mixed with fly ash; there is a groove (4) extending the length of the cold and heat bridge in the middle of the two ends of the concrete shell, and connecting ribs (5) ) to connect the two parts of the block into one. Two multi-reinforced double-cavity composite thermal insulation blocks, the masonry end faces of the concrete mortar used for masonry are in flat contact with each other, and no mortar is filled in the middle of the groove (4) extending the length of the cold and hot bridge. The grooves (4) along the length of the bridge are merged to form an air layer, which enhances the thermal insulation effect of the multi-reinforced double-cavity composite thermal insulation block. the
