Description

Porous composite insulation block

Technical field:

The utility model belongs to building decoration components, in particular to a porous composite thermal insulation block used for building exterior walls.

Background technique:

As we all know, with the further development and renewal of building energy conservation and environmental protection work, it has become a consensus that building exterior walls must use thermal insulation and energy-saving materials. Various new energy-saving building exterior wall materials have been widely used, such as aerated concrete blocks, polystyrene Foam board, thermal insulation mortar plastering, etc., but there is a common problem in these new thermal insulation and energy-saving materials, that is, in order to meet the building energy-saving standards, after adopting energy-saving materials for external walls, the project cost is high and the construction difficulty is increased. There is an energy-saving material for building exterior walls that is easy to construct and low in price.

Invention content:

The purpose of this utility model is to provide a novel porous composite thermal insulation block according to the above disadvantages, which has the advantages of light weight, good structure, thermal insulation, simple construction and low cost.

The utility model is realized in this way. The product includes a lightweight hollow concrete structure layer and a fiber concrete protective layer, a lightweight thermal insulation material block and a thermal insulation concrete rib belt. The porous composite thermal insulation block is square, and it is divided into three layers. structure, the bottom layer is a lightweight hollow concrete layer, the middle layer is a lightweight insulating material block, and the surface layer is a fiber concrete protective layer. There are several hollow holes in the lightweight hollow concrete layer, that is, in the lightweight hollow concrete layer There is a light insulation material block on the top, and the light insulation material block is sandwiched between the lightweight hollow concrete structure layer and the fiber concrete protective layer. There is an insulation concrete rib belt at the end of the light insulation material block, and the insulation concrete rib The belt connects it to form a whole, and a groove is provided at the end of the block. The lightweight hollow concrete layer is provided with round and square core-pulling forming holes. The material is made of ceramsite concrete, slag concrete, plastic concrete and other raw materials, and has light weight and good structural performance.

The concrete of the fiber protection layer of the utility model is a kind of fiber concrete. Such as steel fiber concrete, glass fiber concrete, etc., have strong anti-crack and anti-seepage capabilities, and can effectively prevent rainwater penetration as exterior wall materials.

The light heat insulation material block of the utility model is a light heat insulation material, such as foam plastic, rock wool, slag wool, etc., which has good heat insulation and sound insulation properties, and is cheap.

The concrete in the thermal insulation concrete rib belt of the utility model is a kind of thermal insulation concrete with certain strength and low thermal conductivity, which can effectively connect the hollow concrete structure layer of light aggregate and the thin protective layer of fiber concrete to form As a whole, the "thermal bridge" effect of the rib belt can be reduced as much as possible, and the thermal insulation performance of the lightweight thermal insulation material block can be fully utilized.

Because the block of the utility model adopts the structural form of combining hollow and sandwich, and the concrete used is light concrete, it has light weight and good structural performance. At the same time, because the protective layer on the surface of the light-weight thermal insulation material block is fiber concrete, which has good anti-crack and anti-seepage ability, the wall made of this kind of block can be directly plastered and decorated without additional treatment. The additional construction cost due to the use of energy-saving materials is reduced.
