Abstract

The utility model relates to a self heat-insulating concrete hollow block which integrates a heat-insulating material and a concrete hollow block into a whole. The utility model is composed of the concrete hollow block and the heat-insulating material. The self heat-insulating concrete hollow block is characterized in that the heat-insulating material is filled in the hollow portion of the block, and therefore, the concrete hollow block has the heat-insulating function. Slots are arranged at the top surface, the bottom surface and both end surfaces of the concrete hollow block. When a wall is built, the slots are filled with the finished heat-insulating material or the heat-insulating material made on site, 'heat bridge' between the seams of the blocks can be eliminated, and the whole wall has heat-insulating function. The advantages of the concrete hollow block are fully played, and the problem of the existing concrete hollow block that the heat-insulating property is poor is solved.

Description

The self-heat preservation heat insulation concrete hollow block

The utility model relates to a kind of building-block, especially a kind of self-heat preservation heat insulation concrete hollow block that utilizes the hollow parts filling heat preserving and insulating material of building block.

Build by laying bricks or stones with loam brick mostly in the house that people live, and along with the continuous development of society, human land resources reduces step by step.From protecting human total resource, each state is all adopting the non-loam brick of firing to replace traditional loam brick of firing.Particularly the concrete hollow block development is very fast.No matter sum up situation analysis from project practices at home and abroad, adopt the concrete hollow block of 190 millimeters thick to replace clay solid brick, be as the load bearing wall of multi-storey building or as the infilled wall of frame construction, all is a kind of both economical feasible body of wall.Its advantage of concrete hollow block is that to adopt sand, stone, cement be that raw material is made, and saves the soil, saves the energy consumption of baking bricks, reduce environment pollution, its wall thickness is generally thin than loam brick, therefore can enlarge usage space, and alleviating the building deadweight, its intensity is also than loam brick height.But, be a kind of obstacle of promoting the use of because its thermal and insulating performance is poor always.Heat preserving and insulating material, as polystyrene foam plastics, its thermal and insulating performance is very good, and coefficient of thermal conductivity is 0.030～0.042W/m.K, and with its heat insulating material as aggregate and cement making, coefficient of thermal conductivity also only is 0.058～0.407W/m.k.Loam brick 240 wall coefficient of thermal conductivity are 0.810～0.93W/m.K, and the thermal conductivity ratio loam brick of concrete hollow block is also big.

In order to make body of wall have the effect of better thermal insulation, present technology is the way of body of wall being carried out interior bag, outsourcing or two wall folder insulation layer with heat preserving and insulating material.The way of traditional two wall folder insulation layers certainly will increase construction investment.Bag, outsourcing insulation layer in adopting itself are installed and have been increased difficulty of construction to internal and external ornament, also bring some inconvenience to use.

The purpose of this utility model is to avoid weak point of the prior art, and a kind of improved self-heat preservation heat insulation concrete hollow block is provided.As long as heat preserving and insulating material and the synthetic integral body of concrete hollow block, just can give full play to the advantage of concrete hollow block, overcome its shortcoming, become a kind of new wall materials of high-quality.It makes simple structure, only needs heat preserving and insulating material is filled into the hollow parts of building block.It has not only kept all advantages of concrete hollow block, but also has overcome the shortcoming of concrete hollow block thermal and insulating performance difference, becomes the excellent insulating heat-insulation wall material, needs that no longer body of wall is carried out thermal insulation and handles.If adopt the corner raw material of foamed plastics factory or the waste foam plastics of recovery, become the thermal insulation packing material through material such as broken and cement, its cost can also further reduce, but also the white pollution of these waste foam plastics of minimizing occurring in nature.

The purpose of this utility model is achieved in that this self-heat preservation heat insulation concrete hollow block, by concrete hollow block, heat preserving and insulating material constitutes, heat preserving and insulating material is filled in the hollow parts of building block, make it and building block form one, can can make single row of holes according to the different building-blocks of the requirement of thermal insulation, double hole or many rounds, heat insulating material also can be taked full packing or partially filled to the building block hollow parts.Thereby make concrete hollow block have the function of thermal insulation, in the end face of building-block and bottom surface and two ends leave groove.Heat preserving and insulating material is made into the finished-product material that is fit to the groove size, when building the self-heat preservation heat insulation concrete hollow block by laying bricks or stones, use the finished-product material filling groove while build by laying bricks or stones, reach " heat bridge " problem that horizontal, vertical seam produced that solves owing to forming between the building block, thereby make the full wafer body of wall become the body of wall that a width of cloth has self-heat preservation heat insulation.

The utility model is because only need be at the hollow parts fill insulant material of building block.So construct simply especially, price is also very low, does not need to carry out simultaneously thermal insulation again and handles, so every square metre cost can reduce greatly.

Concrete structure of the present utility model is provided by following enforcement side and accompanying drawing thereof.

Fig. 1 (Fig. 5) is the diagrammatic sketch of bowing according to self-heat preservation heat insulation concrete single row of holes (double hole) building-block that the utility model proposes.

Fig. 2 (Fig. 6) is the side diagrammatic sketch of Fig. 1 (Fig. 5).

Fig. 3 (Fig. 7) is that self-heat preservation heat insulation concrete single row of holes (double hole) building-block that the utility model proposes connects the diagrammatic sketch of bowing.

Fig. 4 (Fig. 8) is the cut-away view that the self-heat preservation heat insulation concrete hollow block that the utility model proposes connects between upper and lower.

As accompanying drawing 1～Fig. 4 (shown in Fig. 5～Fig. 8), this self-heat preservation heat insulation concrete hollow block, constitute by concrete hollow block (1), heat preserving and insulating material (2), end face and bottom surface at concrete hollow block (1) are provided with groove (4), and be provided with groove (3) in the both ends of the surface of concrete hollow block (1), heat preserving and insulating material (2) is filled in the hollow parts of concrete hollow block, with integral body of its structure.Heat preserving and insulating material (2) can fill up the hollow parts among the concrete hollow block (1), also can be partially filled.Joint filling heat insulating material (5) and (6) can be made as finished product in advance also can field fabrication.Heat insulating material (5) is used for the groove (3) at in-filled block two ends, and heat insulating material (6) is used for the groove (4) of in-filled block end face and bottom surface, about eliminating during as concrete block masonry, " heat bridge " of left and right sides seam.Concrete hollow block (1) can also be made into many rounds in addition, and building-block (1) is gone back the building-block of other material except that making of concrete.Heat preserving and insulating material (2) can adopt the material of good heat insulating such as foamed plastics, expanded perlite, expanded vermiculite and be the manufacture of main material with it.
