Abstract

The utility model relates to a building material structure, particularly a heat-protective wall body which is suitable for high-rise buildings, various public buildings and industrial factory buildings. The heat-protective wall body comprises an outer wall-face layer and a hollow layer. A mixed layer which is provided with space adhesive, cement and water is arranged between a concrete layer and a heat-protective layer with a self-extinguished polyphenylene plate, so an outer wall-face layer is formed in a compounding mode. The hollow layer is composed of two concrete bodies which are served as building holes of the wall body. Additionally, an inserting pin is arranged in the outer wall-face layer. The utility model has the advantages of reasonable structure, convenient construction and good heat-protective effect. The heat-protective wall body eliminates the effect of a cold bridge, reduces the cost, and overcomes the defect that the prior art uses a large quantity of clay bricks and destroys farmland. Additionally, because the outer wall-face layer adopts the technology of the inserting pin, the heat-protective layer of the wall body and the wall body can be reliably ensured not to shed.

Description

The concrete wall composite thermal insulation hollow block

The utility model relates to a kind of constructional materials structure, is meant a kind of highrise building that is applicable to especially, various public buildings and industrial premises external heat insulating wall.

At present, the heat preserving method in present house, heating area is except that using heating equipment in the winter time, and many exterior wall is adopted thickeied thick clay tile wall of wall 50-70CM or concrete wall and pasted external wall insulation.Though these practices can play certain insulation effect, weak point is that thickness of wall body is big, has dwindled usable floor area; In addition, owing to use loam brick in a large number, damage the consequence in arable land; In addition, clay tile wall thermal transmittance height, heat insulation effect is poor; Paste panels with interior insulating layer for external wall for another example, though can rise, also dwindled usable floor area, and located also to exist the cold bridge problem at beam column, window angle etc. to heat preservation effect; And the stickup external wall insulation, though can reduce the phenomenon of cold bridge, its trouble of constructing, but also can not thoroughly eliminate the hidden danger that insulation layer and body of wall come off.

The purpose of this utility model is to overcome the deficiency in the background technology and provides a kind of field of neither ruining to bake bricks, do not add thick wall body again, also need not in construction to paste any adiabator plate, and in the building wall construction one step completed concrete wall composite thermal insulation hollow block.

The utility model purpose is achieved in that it comprises outer wall surface and hollow layer, is characterized in that: its outer wall surface is to be composited by the mixed layer that is provided with space cementing agent, cement and water between layer of concrete and the self-extinguishing type polyphenyl plate heat preserving layer; Its hollow layer is to be made of two concrete bodies as body of wall block orifice.

Wherein, in described outer wall surface, also can be provided with contact pin, draw intensity, thereby thoroughly eliminate the hidden danger that insulation layer and layer of concrete come off with the bonding tension that strengthens between wall insulating layer and the layer of concrete.

Described self-extinguishing type polyphenyl plate heat preserving layer is the self-extinguishing type polystyrol plastic foam plate.

Described contact pin can be that an end is the rib-loop type, and the other end is flat ring-like metal ferrule.

Advantage of the present utility model is: rational in infrastructure, and easy construction; The thermal resistance value height, high insulating effect; Eliminated the influence of cold bridge; Reaching under the condition of same heat insulation effect, can save the heat insulating material of 40-50%, reduced cost, and can make its usable floor area increase about 1.5%; And,, damage the shortcoming in arable land so overcome a large amount of loam bricks that use in the prior art because of its material is the general industry material; In addition, owing to adopted the technology of contact pin in the outer wall surface, be the reliable assurance that makes never drop-off between wall insulating layer and the body of wall.The utility model not only can play the effect of insulation in the winter time, and can also play heat insulation effect in summer.The utility model is a kind of novel wall body structure.

Fig. 1 is the utility model structure sectional view.

Fig. 2 is a side structure sectional view of the present utility model.

Below in conjunction with Figure of description and embodiment, the utility model is further described.

As shown in Figure 1, 2, the utility model comprises outer wall surface and hollow layer, and its outer wall surface is to be composited by the mixed layer 2,4 that is provided with space cementing agent, cement and water between layer of concrete 1,5 and the self-extinguishing type polyphenyl plate heat preserving layer 3; Its hollow layer is to be made of two concrete bodies 7 as body of wall block orifice 6.Can be according to different regions to antidetonation, shockproof requirement, in body of wall is built orifice 6, be provided with upright to or transverse reinforcement, with the mechanical index that guarantees that body of wall needs.In addition, in described outer wall surface, also be provided with metal ferrule 8.

In force, be to be the rib-loop type, and the other end is flat ring-like metal ferrule, sticks the mixed pulp of space cementing agent, cement and water, and fills its jack, put into the extruding of pattern machine again, to form wall heat insulation building blocks with this mixed pulp with being processed into an end.
