Description

One protection and one partition composite insulation block

technical field

The utility model relates to the field of construction and self-insulation materials, in particular to a composite insulation block with one protection and one insulation for external use in buildings. the

Background technique

The wall made of thermal insulation blocks and mortar can be used as the load-bearing wall and maintenance wall of industrial and civil buildings. The current main structure of this thermal insulation block is composed of a concrete shell and foamed concrete or filled foam filled in the cavity of the concrete shell. It has good heat preservation and heat insulation effects and good fire prevention, durability, sound insulation, compression resistance, waste utilization and other properties. This is the case for the patents we have developed and applied for before, such as "Two Guarantees and One Composite Thermal Insulation Block" (Patent No. 200920299050.9), "Double-cavity Composite Thermal Insulation Block" (Patent No. 201020674058.1). But this kind of composite thermal insulation block has problems such as heavy weight, relatively high cost, inconvenient installation of pipes, embedding, and installation of heavy objects. the

Invention content:

The purpose of this utility model is to overcome above-mentioned shortcoming, get rid of the old and bring forth the new, and design a kind of one to keep one to separate the compound thermal insulation building block. The block can effectively reduce the weight of the block and reduce the cost of the block; by extending the heat transfer path and adopting the double insulation method of the cavity layer and the insulation body, the heat transfer coefficient is greatly reduced; it is convenient to pass pipes and embed wires in the cavity of the block , It can be filled with concrete, which is convenient for installing heavy objects; the block modulus meets the building modulus requirements. the

The utility model uses the following technical solutions

A composite thermal insulation block with one protection and one partition, comprising a hollow concrete shell (1), a concrete shell cavity (2) and an inorganic thermal insulation foam (4) filled in another concrete shell cavity (3) ) composition; the one-guarantee-one-compartment composite thermal insulation block uses concrete mortar to build a trapezoidal cross-section with two smooth protrusions (6), and the middle layer of the end surface of the concrete shell is added to extend the length of the cold and hot bridge. U-shaped groove (5). the

The beneficial effect of the utility model is that the one-guarantee-one-compartment composite heat-insulation block has a reasonable structure, and is an improvement and enhancement of the double-cavity composite heat-preservation block, two-guarantee-one-partition composite heat preservation block, and the like. It can reduce the weight of the block, reduce the cost of the block, and thus reduce the project cost; by extending the heat transfer path and adopting the double insulation method of the cavity layer and the insulation body, the heat transfer coefficient can be greatly reduced; The line is convenient, the concrete can be filled, and it is convenient to install and hang heavy objects. At the same time, after testing, the block strength is guaranteed, the heat preservation effect is remarkable, and the energy saving effect is also very obvious. After popularization and use, it will have good economic and social benefits. the

Detailed ways

Example 1

One guarantee and one partition composite thermal insulation block, first make the hollow concrete shell (1), there are two cavities in the hollow concrete shell (1), one of the cavities (2) is not filled with any thermal insulation material, and the hollow concrete shell (1) is used Insulation and thermal insulation, the other cavity (3) is filled with phosphogypsum or desulfurized gypsum or inorganic thermal insulation foam (4) mixed with cement and fly ash; The end face of the mortar masonry is a trapezoidal cross-section with two flat protrusions (6), and a U-shaped groove (5) is added to the middle layer of the end face of the concrete shell masonry to extend the length of the cold and heat bridge; Composite thermal insulation block, when masonry has two flat protrusions (6), the masonry end faces using concrete mortar are in flat contact with each other, and a cavity is formed in the middle to accommodate the masonry concrete mortar, U-shaped groove (5) The middle is not filled with mortar, and the two U-shaped grooves (5) merge to form an air layer, which enhances the thermal insulation effect of the one-guarantee-one-compartment composite thermal insulation block. the

Claims (1)

1.
