Description

Slash core composite insulation block

technical field

The utility model relates to the field of construction and thermal insulation materials, in particular to a slash core 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. At present, the main structure of this kind of thermal insulation block is composed of concrete shell and foamed concrete or foam slurry filled in the cavity of the concrete shell, which has good heat preservation and heat insulation effect 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 this utility model is to overcome the above-mentioned shortcoming, introduce the new through the old, and design a kind of slash core 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 slash core composite thermal insulation block, consisting of a hollow concrete shell (1), a smaller cavity (2) in the concrete shell, and a longer cavity (3) filled in the concrete shell It is composed of foam slurry (4), and there is a groove (5) extending the length of the cold and heat bridge in the middle of the end faces of the two ends of the concrete shell.

2. The groove (5) 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 slash core composite thermal insulation block has a reasonable structure, and 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.

In Figure 1-2, 1. Concrete shell, 2. Smaller cavity in the concrete shell, 3. Longer cavity in the concrete shell, 4. Inorganic thermal insulation foam, 5. Extending the length of the cold and thermal bridge of the groove.

Detailed ways

Example 1

Slash core composite thermal insulation block, firstly make the hollow concrete shell (1), the hollow concrete shell (1) has a smaller cavity (2) and a longer cavity (3), in the longer The cavity (3) is filled with phosphogypsum or desulfurized gypsum or inorganic thermal insulation foam (4) mixed with cement and fly ash; the smaller cavity (2) is not filled with any thermal insulation material, and the cavity heat insulation, insulation. There is a U-shaped groove (5) in the middle of the end faces of the two ends of the concrete shell to extend the length of the cold and hot bridge; two slash-core composite thermal insulation blocks, and the masonry end faces of the concrete mortar used for masonry are in flat contact with each other. Mortar is not filled in the middle of the groove (5), and the two grooves (5) are merged to form an air layer, which enhances the thermal insulation effect of the slash core composite thermal insulation block.

Claims (2)

1. slash core composite heat insulation block, it is characterized in that by cavity (2) less in hollow concrete shell (1), the concrete shell and be filled in the interior foam slip (4) of cavity (3) long in the concrete shell forming, there is the groove (5) that prolongs cold-heat bridge length at the place in the middle of the end face of concrete shell two ends.

2. a kind of slash core composite heat insulation block according to claim 1, it is characterized in that the groove (5) of place's prolongation cold-heat bridge length is U font groove or V-shape groove or semi-circular groove or ellipse groove or square groove in the middle of the end face of described concrete shell two ends.
