Abstract
The utility model relates to hollow thermal insulation bricks which belong to building materials. During the process of the production of the hollow building bricks, heat-reflecting materials are extruded to be embedded on ribs which are parallel to the heat flow direction. So the heat-reflecting materials are arranged in holes and are vertical to the heat flow direction, such as setting an aluminium foil whose radiating system is small, etc. The hollow thermal insulation brick of the utility model has the advantages of large heat resistance value and favorable thermal insulating property, belongs to an ideal building material for effectively reducing the heat consumption of outer wall of a building, and realizes building energy conservation.
Description
The utility model belongs to constructional materials, relates generally to a kind of building-block that is used for external wall.
At present, the building-block that China now produces, without other material interval, it is poor to exist heat-insulating property, can not satisfy the insulation requirement of skin, has increased the energy consumption of building in the general hole.
The utility model purpose is the high-efficiency insulated building-block that proposes a kind of good heat insulating, reduces the heat consumption by skin, saves the energy consumption by skin.
The heat-insulating property of building-block is subjected to the influence of hole thermal resistance, and the thermal resistance of hole depends on row's number of hole.Boundary layer thickness on thickness and each interface and fix density of radiate heat exchange therebetween.In the interior total heat output of the hole of building-block, the ratio that radiation heat transfer accounts for is usually more than 70%, and hole row number is many more simultaneously, and the thermal resistance of building-block is also just big more.The technical solution of the utility model is established heat-reflecting material on the vertical heat flow direction in the building-block hole, can not only effectively stop radiation heat transfer in the hole, and increased row's number of hole, thereby increase the thermal resistance of building-block, improve the heat-insulating property of building-block, minimizing realizes the purpose of building energy conservation by the heat consumption of skin.
Accompanying drawing is a stereogram of the present utility model.
Below in conjunction with accompanying drawing the utility model is elaborated:
With reference to the accompanying drawings, 1 is the rectangle hollow building block body among the figure, the 2nd, the vertical hole of rectangle fillet on the building block body, the 3rd, the heat-reflecting material on the vertical heat flow direction, be embedded on the rib 4 of parallel direction of heat flow, to stop the radiation heat transfer and the row's number that increases hole in the hole, improve the heat-insulating property of building-block.Heat-reflecting material in the said hole on the vertical heat flow direction, can be to establish the individual layer heat-reflecting material, in order further to improve the heat insulation effect of building-block, also can be to establish the multilayer heat-reflecting material on the vertical heat flow direction in the hole, and the many more heat insulation effects of the number of plies be good more.Said heat-reflecting material can directly embed in the rib in producing the building-block process, is fixed in the building-block by extruding.Said heat-reflecting material, aluminium foil for example. aluminium flake. heat-reflecting glasss etc., these heat-reflecting materials all have the effect that reduces radiation heat transfer in the hole, also all have the effect that hole increases hole row number that cuts off simultaneously, heat insulation effect is all good, but comparatively economical with aluminium foil.So the utility model is aluminium foil extruding in producing the building-block process is embedded in the rib of building-block and to be fixed on the hole vertical heat flow direction.According to surveying and determination, when building-block cavity thickness was 0.13 meter, not establishing the heat-reflecting material thermal resistance value was 0.181 square metre. degree/watt, the hole thermal resistance value is 2x0.499 square metre when establishing one deck aluminium foil. degree/watt, be not establish 5.52 times of heat-reflecting material; If the thermal resistance value of two-layer aluminium foil hole is 2x0.473+0.688 square metre. degree/watt, be not establish 9.03 times of heat-reflecting material ..., the set aluminium foil number of plies is many more, and the thermal resistance value of hole is also big more.
Hollow thermal insulation brick of the present utility model is compared with general building-block, only be provided with heat-reflecting material in its hole vertical heat flow direction, can in the building-block production process, finish, need not to increase in addition production process, but greatly improved the thermal resistance of hole, for the heat-insulating property that improves building-block, reduce by the skin heat consumption, realize that building energy conservation is significant.
