Abstract
The utility model discloses a double-cavity compound heat insulation building block which consists of a hollow concrete shell 1 and an inorganic heat insulation foam body 2 which is made by mixing ardealite or desulfurization gypsum and concrete and filled in a cavity of the concrete shell, wherein two smooth bulges 5 are arranged on the end surface of the double-cavity compound heat insulation building block, the end surface is built by concrete mortar, and the height*width of the ladder-shaped section of each of the smooth bulges 5 is 5mm* 15mm-5mm*30mm, the middle layer of the end surface built by the concrete shell is additionally provided with a U-shaped groove 3 for extending the length of a cold and hot bridge, meanwhile, after inspection, the strength of the bloc is ensured, the heat insulation effect is obvious, the energy saving effect is also obvious, and the block has good economic and social benefits after being popularized and used.
Description
Technical field
Utility model relates to building and self-thermal insulation material field, especially relates to a kind of two-chamber composite heat insulation block of building external application.
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 the filled and process formation.The four sides all need use the coagulation mortar to build by laying bricks or stones when using building block, though the foaming body coefficient of thermal conductivity is low, but because concrete coefficient of thermal conductivity height, concrete shell and concrete mortar all can conduct heat, its cavity mostly is regular square and cuboid again, this just makes that the heat-transfer path of concrete shell and concrete mortar is short, and its effect of heat insulation is limited.Occur though have some different in nature building blocks (as the tongue-and-groove type insulation blocks) of blocking cold and hot bridge, equipment has high input, and production efficiency is low, T-shaped wall, right angle wall, the body of wall inconvenience building of turning round, and construction module and existing building block modulus do not meet, and use inconvenience.
Analogous cases just occurred in Chinese patent literature, as patent No. ZL 200520091572.1, the utility model name is called " building block of the no vertical masonry joint concrete heat preserving exterior wall of abnormity " and patent No. ZL 200720013576.7, and it is exactly this situation that the utility model name is called " a kind of core foamed concrete insulation blocks ".
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming, designs a kind of passing through and prolongs heat-transfer path, reduces thermal transmittance significantly, and the building block modulus meets the two-chamber composite heat insulation block of construction module requirement.
The following technical scheme of the utility model
A kind of two-chamber composite heat insulation block is by hollow concrete shell 1 be filled in ardealite in the concrete shell cavity 3 or the inorganic heat preservation foaming body 2 of desulfurated plaster and cement mixing is formed; The two-chamber composite heat insulation block use the coagulation mortar build by laying bricks or stones trapezoid cross section that end face has two smooth projection 5 places for high * widely be 5mm * 15mm ∽ 5mm * 30mm, concrete shell is built the U font groove 3 that place, end face intermediate layer adds the cold and hot bridge length of prolongation by laying bricks or stones.
The beneficial effects of the utility model, the two-chamber composite heat insulation block is rational in infrastructure, the concrete shell intermediate layer adds the groove that prolongs cold and hot bridge length, guarantee block strength simultaneously, through detecting, heat insulation effect is remarkable, and energy-saving effect is also 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 two-chamber composite heat insulation block;
The structural representation of Fig. 2 utility model two-chamber composite heat insulation block.
Among Fig. 1-2,1. concrete shell, 2. the inorganic heat preservation foaming body 3. prolongs the U font groove of cold and hot bridge length, 4. concrete shell cavity, 5. two smooth projections of end face.
The specific embodiment
Embodiment 1
The two-chamber composite heat insulation block is at first made hollow concrete shell 1, then, is filled in the ardealite in the concrete shell cavity 4 or the inorganic heat preservation foaming body 2 of desulfurated plaster and cement mixing in the hollow concrete shell cavity; The two-chamber composite heat insulation block that obtains uses the coagulation mortar to build end face by laying bricks or stones has two smooth protuberant bars 5 to be height * wide trapezoid cross section as 5mm * 15mm ∽ 5mm * 30mm, and place, concrete shell intermediate layer adds the U font groove 3 that prolongs cold and hot bridge length; Two two-chamber composite heat insulation blocks, use the coagulation mortar to build the mutual smooth contact of end face that end face has two smooth prominences 5 by laying bricks or stones, cavity of middle formation holds builds the coagulation mortar by laying bricks or stones, do not insert mortar when building by laying bricks or stones in the middle of the U font groove 3, the U font groove of the middle cold and hot bridge length of prolongation that adds, merge and form an air layer, the heat insulation effect of enhancing two-chamber composite heat insulation block.
Claims (1)
1. two-chamber composite heat insulation block is characterized in that by hollow concrete shell (1) and is filled in ardealite in the concrete shell cavity or the inorganic heat preservation foaming body (2) of desulfurated plaster and cement mixing is formed; The two-chamber composite heat insulation block use the coagulation mortar build by laying bricks or stones trapezoid cross section that end face has two smooth prominences (5) for high * widely be 5mm * 15mm ∽ 5mm * 30mm, concrete shell is built the U font groove (3) that place, end face intermediate layer adds the cold and hot bridge length of prolongation by laying bricks or stones.
