Post-foamed forming foam concrete sandwich composite heat-preservation fireproof building block

Abstract

The invention discloses a post-foamed forming foam concrete sandwich composite heat-preservation fireproof building block which is characterized by consisting of a concrete inner leaf block body 3, a post-foamed forming foam concrete heat preservation composite plate 2, a concrete outer leaf block body 1 and pull connection pieces 4, which are compounded with one another, wherein a plurality of vertical female dovetail grooves 5 are formed in one large surface of the concrete inner leaf block body 3; a plurality of male dovetail grooves 6 are formed in one large surface of the outer leaf block body 1, and the number of male dovetail grooves 6 is the same as that of female dovetail grooves 5; the pull connection pieces 4 are arranged in the female dovetail grooves 5 of the inner leaf block body 3 and the male dovetail grooves 6 of the outer leaf block body 1; by the pull connection pieces 4 and dovetail grooves formed by post-foamed forming foam concrete, the inner leaf block body 3 and the outer leaf block body 1 are firmly connected in a pull manner; two vertical end faces of the post-foamed forming foam concrete heat preservation composite plate 2 exceed the length of half of an ash slit; the upper part and the lower part of the post-foamed forming foam concrete heat preservation composite plate 2 are connected through a foam concrete heat preservation sealing strip 12 of which the section is horizontal; therefore, an integrated heat preservation isolation wall is formed, so that a building block cold bridge is cut off, and fire can be prevented.

Description

technical field [0001] The invention relates to a new type of building material, in particular to a post-foaming foam concrete sandwich composite thermal insulation and fireproof block for masonry walls. Background technique [0002] In order to achieve sustainable development, the country enforces the energy-saving building, which has increased energy-saving from 50% to 65%. Ordinary concrete blocks can no longer meet the energy-saving requirement of 65%. There are many problems in the current polystyrene board thin plaster exterior wall insulation system: (1) the external insulation layer of the exterior wall cracks; (2) the external insulation layer falls off; (3) the impact resistance of the insulation layer is poor; (4) the insulation material Different lifespan from buildings; (5) prone to major fires, etc. In recent years, the major fires in building external insulation include: Beijing CCTV new site fire on 2009-02-09, Shanghai Jiaozhou Road fire on 2010-11-15; Shen...

Problems solved by technology

[0002] In order to achieve sustainable development, the state enforces energy-saving buildings, which have increased energy-saving from 50% to 65%. Ordinary concrete blocks can no longer meet the energy-saving requirements of 65%.

There are many problems in the current polystyrene board thin plaster exterior wall insulation system: (1) the external insulation layer of the exterior wall cracks; (2) the external insulation layer falls off; (3) the impact resistance of the insulation layer is poor; (4) the insulation material Different lifespan from buildings; (5) prone to major fires, etc.

Some have built-in inorganic thermal insulation materials or organic thermal insulation materials in the concrete block holes, but they are connected by concrete ribs to form concrete cold bridges, which affect the thermal insulation performance

And the improved utility model patent-"combined thermal insulation block" (200520001775.7), is a sandwich composite thermal insulation block composed of concrete perforated block 1, concrete surface layer block 3 and polystyrene thermal insulation board 2, although the concrete The cold bridge formed by the ribs, but there is still a fatal technical flaw: the problem of fire prevention has not been solved
