Abstract

The utility model discloses a multi-rib type two-insulation and two-cavity composite heat insulating block. The heat insulating block comprises a hollow concrete shell (1), two smaller cavities (2) in the concrete shell and foam slurry (4) filled in two longer cavities (3) in the concrete shell, wherein grooves (5) lengthening cold and heat bridges are arranged in the middle of the two ends of the concrete shell; and connecting ribs (6) connect the two parts of the block into a whole. The composite heat insulating block has a reasonable structure, obvious heat insulating effect and very obvious energy saving effect and can produce good economic and social benefits.

Description

Multi-reinforced two-proof and two-hole composite thermal insulation block

technical field

The utility model relates to the field of building and thermal insulation materials, in particular to a multi-reinforced two-hole and two-hole 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 multi-reinforced two-guaranteed and two-hole 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 multi-reinforced two-hole and two-hole composite thermal insulation block, which consists of a hollow concrete shell (1), two smaller cavities (2) in the concrete shell and two longer cavities filled in the concrete shell. The foam slurry (4) in the cavity (3) of the concrete shell has a groove (5) extending the length of the cold and heat bridge in the middle of the two ends of the concrete shell, and the connecting rib (6) connects the two parts of the block into a One.

2. The groove (5) extending the length of the cold and heat bridge at the middle of both 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 multi-reinforcement type two-guarantee and two-hole 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 multi-reinforced two-reinforcement and two-hole composite thermal insulation block, firstly, the hollow concrete shell (1) is prepared, and the hollow concrete shell (1) has a smaller cavity (2) and a longer cavity (3). The longer cavity (3) is filled with phosphogypsum or desulfurized gypsum or the 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 Cave heat insulation and heat preservation. There is a groove (5) extending the length of the cold and heat bridge in the middle of the two ends of the concrete shell, and the connecting rib (6) connects the two parts of the block into one. Two multi-reinforced two-reinforcement and two-hole composite thermal insulation blocks, the masonry end faces of the concrete mortar used for masonry are in flat contact with each other, the middle of the groove (5) is not filled with mortar, and the two grooves (5) are combined to form one The air layer enhances the thermal insulation effect of the multi-reinforced two-hole and two-hole composite thermal insulation block.

Claims (2)

1. muscle type more than a kind two is protected two hole composite heat insulation blocks, it is characterized in that it by two less cavitys (2) in hollow concrete shell (1), the concrete shell and be filled in the concrete shell two foam slips (4) in the long cavity (3) forming, there is the groove (5) that prolongs cold-heat bridge length at the place in the middle of the concrete shell two ends, and dowel (6) links into an integrated entity two parts of building block.

2. a kind of many muscle type two according to claim 1 is protected two hole composite heat insulation blocks, 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 described concrete shell two ends.
