CN202850324U - Composite thermal-insulating block with single cavity - Google Patents

Abstract

The utility model discloses a single-cavity composite thermal insulation block, which is composed of a hollow concrete shell (1) and foam slurry (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 of the body. The single-cavity composite thermal insulation block has reasonable structure, remarkable thermal insulation effect and obvious energy-saving effect, and can produce good economic and social benefits.

Description

Single cavity composite insulation block

technical field

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

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.

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 single-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 utility model adopts the following technical solutions

1. A single-cavity composite thermal insulation block, which is composed of a hollow concrete shell (1) and foam slurry (3) filled in the cavity (2) of the concrete shell. There is a Grooves (4) extending the length of the thermal bridge.

2. The groove (4) extending the length of the cold and heat bridge at the middle of the two ends of the concrete shell is a U-shaped groove or a V-shaped groove or a semicircular groove or an elliptical groove or a square groove .

The beneficial effect of the utility model is that the structure of the single-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.

Detailed ways

Example 1

For the single-cavity composite thermal insulation block, the hollow concrete shell (1) is first made, and the hollow concrete shell (1) has a cavity (2), and the cavity (2) is filled with phosphogypsum or desulfurized gypsum or cement and powder An inorganic thermal insulation foam (3) mixed with coal ash; a U-shaped groove (4) extending the length of the cold and thermal bridge is provided in the middle of the two end faces of the concrete shell; two single-cavity composite thermal insulation blocks, The end faces of the masonry with concrete mortar are in flat contact with each other, the middle of the groove (4) is not filled with mortar, and the two grooves (4) are combined to form an air layer, which enhances the thermal insulation effect of the single-cavity composite thermal insulation block.

Claims (2)

1. A single-cavity composite thermal insulation block is characterized in that it is composed of a hollow concrete shell (1) and a foam slurry (3) filled in the cavity of the concrete shell (2), and the two end faces of the concrete shell There is a groove (4) extending the length of the cold and heat bridge in the middle. 2. A single-cavity composite thermal insulation block according to claim 1, characterized in that the groove (4) extending the length of the cold and heat bridge at the middle of the two end faces of the concrete shell is a U-shaped groove or V-shaped groove or semicircular groove or elliptical groove or square groove.
