Abstract

The utility model discloses a semi-surrounded composite heat preservation building block. The semi-surrounded composite heat preservation building block consists of a hollow concrete shell body (1), cavities (2) and inorganic heat preservation foam (4), wherein the cavities (2) are formed in the concrete shell body and are located at two sides, and the inorganic heat preservation foam (4) is filled in a middle cavity (3) in the concrete shell body; and a broken bridge (5) which is used for hindering cold/heat transfer is arranged at each of the two ends of the concrete shell body. According to the semi-surrounded 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

Semi-enclosed composite thermal insulation block

technical field

The utility model relates to the field of construction and thermal insulation materials, in particular to a semi-enclosed 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 high heat transfer coefficient. the

Contents of the invention

The purpose of this utility model is to overcome the above-mentioned shortcoming, introduce the new through the old, and design a kind of semi-enclosed composite thermal insulation block. The block has the advantages of previous similar composite thermal insulation blocks, and at the same time blocks the thermal bridge, so that the thermal insulation and heat insulation effect of the block is better. the

The utility model adopts the following technical solutions

A semi-enclosed composite thermal insulation block, consisting of a hollow concrete shell (1), cavities (2) on both sides of the concrete shell, and inorganic inorganic materials filled in the middle cavity (3) of the concrete shell. It consists of thermal insulation foam (4), and a broken bridge (5) for hindering cold and heat transfer is respectively arranged at both ends of the concrete shell. the

The beneficial effect of the utility model is that the structure of the semi-enclosed composite thermal insulation block is reasonable, and it is an improvement and enhancement of the previous similar composite thermal insulation block. The thermal bridge is blocked, so that the heat preservation and heat insulation effect of the block is better. The energy-saving effect is very obvious, and there will be good economic and social benefits after being popularized and used. the

Detailed ways

Example 1

For the semi-enclosed composite thermal insulation block, the hollow concrete shell (1) is first made, and the hollow concrete shell (1) has cavities (2) on both sides of the concrete shell and a hollow in the middle of the concrete shell. Cavity (3), the cavity (3) in the middle of the concrete shell is filled with phosphogypsum or desulfurized gypsum or cement and fly ash mixed inorganic insulation foam (4); the cavity on both sides of the concrete shell The cavity (2) is not filled with any heat insulating material, and the cavity is used for heat insulation and heat preservation. There is a broken bridge (5) at both ends of the concrete shell that hinders cold and heat transfer; two semi-enclosed composite thermal insulation blocks, the masonry end faces of which are made of concrete mortar are in flat contact with each other to prevent cold and heat transfer Mortar is not filled in the middle of the broken bridge (5), so as to enhance the thermal insulation effect of the semi-enclosed composite thermal insulation block. the

Claims (1)

1. A semi-enclosed composite thermal insulation block is characterized in that it is composed of a hollow concrete shell (1), a cavity (2) on both sides in the concrete shell and a cavity (2) in the middle of the concrete shell filled in 3) is composed of inorganic thermal insulation foam (4), and there is a broken bridge (5) at both ends of the concrete shell that hinders cold and heat transfer.
