The structures of the four cavities are two cavities (2) in the concrete shell. ) is filled with foam slurry (4), and the other two cavities (3) are not filled with any insulation material; or the two cavities (2) in the concrete shell are not filled with any insulation material, and the other two cavities (3) ) is filled with foam slurry (4); 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. Z-shaped core composite thermal insulation block has reasonable structure, remarkable thermal insulation effect, obvious energy saving effect, and can produce good economic and social benefits.

Description

Z-core composite thermal insulation block

technical field

The utility model relates to the field of construction and thermal insulation materials, in particular to a Z-shaped 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. 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 this utility model is to overcome the above-mentioned shortcoming, introduce the new through the old, and design a kind of composite thermal insulation block with Z-shaped core. 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 utility model adopts the following technical solutions

1. A Z-core composite thermal insulation block, which is composed of a hollow concrete shell (1) and four cavities. The structure of these four cavities is that two cavities (2) in the concrete shell are filled with foam materials slurry (4), and the other two cavities (3) are not filled with any insulation material; or the two cavities (2) in the concrete shell are not filled with any insulation material, and the other two cavities (3) are filled with foam Slurry (4); grooves (5) extending the length of the cold and heat bridges are arranged 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 structure of the Z-shaped core composite thermal insulation block is reasonable, which is an improvement and enhancement of the previous similar composite thermal insulation block, which blocks the thermal bridge, makes the thermal insulation and heat insulation effect of the block better, and saves energy. It is obvious that there will be good economic and social benefits after popularization and use.

Detailed ways

Embodiment 1 (the scope of the present utility model is not limited thereto, and its scope of protection is described in each right of claim.)

Z-shaped core composite thermal insulation block, first make the hollow concrete shell (1), there are four cavities in the hollow concrete shell (1), and the cavity (2) is filled with phosphogypsum or desulfurized gypsum or cement and powder The inorganic thermal insulation foam (4) mixed with coal ash is not filled with any thermal insulation material in the other two cavities (3), and the cavity is used for thermal insulation and thermal 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 Z-shaped core composite thermal insulation blocks, 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) merge to form an air layer, which enhances the thermal insulation effect of the Z-shaped core composite thermal insulation block.

Claims (2)

1. Z-shaped core composite heat insulation block, it is characterized in that being formed by hollow concrete shell (1) and four cavitys, the structure of these four cavitys is two cavitys (2) the filled and process slips (4) in the concrete shell, and two cavitys (3) are not then filled any heat insulating material in addition; Or two cavitys (2) in the concrete shell do not fill any heat insulating material, in addition two cavitys (3) filled and process slip (4) then; 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 Z-shaped 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.
