Porous one word core composite heat insulation block
Technical field
The utility model relates to building and field of heat insulating materials, is specifically related to a kind of porous for building one word core composite heat insulation block.
Background technology
With the body of wall that insulation blocks and mortar are built by laying bricks or stones, can do the load bearing wall of industry and civilian construction and safeguard wall.The present primary structure of this insulation blocks is to adopt concrete shell and be filled in the interior foamed concrete of concrete shell cavity or foam slip formation.Have preferably insulation, effect of heat insulation and good fire prevention, durable, sound insulation, resistance to compression, the sharp performance such as useless.But mostly exist thermal transmittance to cross the problems such as high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, weeds out the old and bring forth the new, and designs a kind of porous one word core composite heat insulation block.The advantage of similar composite heat insulation block before this building block has makes the end face at concrete shell two ends prolong cold-heat bridge length simultaneously, thereby the insulation of building block, effect of heat insulation are better.
The utility model by the following technical solutions
1, a kind of porous one word core composite heat insulation block, foam slip (4) by the less cavity (2) in both sides in hollow concrete shell (1), the concrete shell and in the middle of being filled in the concrete shell in the larger cavity (3) forms, and there is the groove (5) of prolongation cold-heat bridge length at the two ends of concrete shell.
2, the groove (5) of described concrete shell two ends prolongation cold-heat bridge length is U font groove or V-shape groove or semi-circular groove or ellipse groove or square groove.
The beneficial effects of the utility model, porous one word core composite heat insulation block is rational in infrastructure, is improvement and the raising to former similar composite heat insulation block.Make the end face at concrete shell two ends prolong cold-heat bridge length, thereby the insulation of building block, effect of heat insulation are better, energy-saving effect is fairly obvious, and good economic benefit and social benefit are arranged after promoting the use of.
Description of drawings
The structural representation of Fig. 1 utility model porous one word core composite heat insulation block;
Fig. 2 utility model porous one word core composite heat insulation block is the structural representation of filled and process slip not;
Among Fig. 1-2,1. concrete shell, the 2. less cavity in both sides in the concrete shell, 3. in the concrete shell in the middle of larger cavity, 4. the inorganic heat preservation foams 5. prolong the groove of cold-heat bridge length.
The specific embodiment
Porous one word core composite heat insulation block, at first make hollow concrete shell (1), hollow concrete shell (1) is inner the less cavitys in both sides (2) and middle larger cavity (3), the inorganic heat preservation foaming body (4) that filling ardealite or desulfurated plaster or cement mix with flyash the larger cavity in centre (3) in; The less cavity (2) in both sides is not then filled any heat insulating material, takes heat insulation, the insulation in hole; There is the U font groove (5) that prolongs cold-heat bridge length at the concrete shell two ends.Two porous one word core composite heat insulation blocks, that uses the coagulation mortar when building by laying bricks or stones builds the mutual smooth contact of end face by laying bricks or stones, do not insert mortar in the middle of the groove (5), two grooves (5) merge air layer of formation, strengthen the heat insulation effect of porous one word core composite heat insulation block.
