Composite sandwich heat-preservation plate with bridge cut-off heat insulation strip and manufacturing method of composite sandwich heat-preservation plate

Abstract

The invention provides a composite sandwich heat-preservation plate with a bridge cut-off heat insulation strip and a manufacturing method of the composite sandwich heat-preservation plate. The heat-preservation plate comprises a heat-preservation layer, reinforced concrete face layers and the bridge cut-off heat insulation strip arranged on the circumference of the heat-preservation layer, wherein two faces and the periphery of the heat-preservation layer are covered with the reinforced concrete face layers. The heat-preservation plate can be manufactured to be in a flat-plate shape or in an L shape. Perforated holes which are distributed in a crossed mode and used for combining the heat-preservation layer with the face layers into a whole are formed in the heat-preservation plate. A cavity is reserved in the bridge cut-off heat insulation strip so that an anchoring part can be placed in the cavity and can be used for being connected with the adjacent heat-preservation plate in assembling. A wall is provided with a prefabricated reinforced concrete plate which is attached to the heat-preservation plate in a high adhesion strength, and the heat-preservation plate has the advantages of being high in adhesion strength and assembling construction speed, capable of being firmly combined with the structural wall and low in cost and can be widely used for heat preservation of various buildings.

Description

technical field [0001] The invention belongs to the field of building components and construction, and relates to a thermal insulation board used for building walls or frames, in particular to a composite sandwich thermal insulation board with bridge-breaking thermal insulation strips and a manufacturing method thereof. Background technique [0002] In today's situation of energy shortage, outstanding building energy consumption, and accelerated urbanization, building energy conservation has become an important issue in my country's urban and rural development, and the market demand for building energy-saving technologies and products will increase sharply. [0003] From the perspective of building construction, the most obvious impact on building energy consumption is the thermal performance of the envelope structure, that is, the thermal insulation performance involving the external wall, roof structure, and door and window settings. [0004] In the thermal performance of ...

AI Technical Summary

Problems solved by technology

Due to the limitation of construction conditions, there are problems that the insulation material is not firmly pasted, the pasting speed is slow, and it is easy to be hollow and fall off.

In addition, some insulation materials are combustible, and there are fire hazards in the process of construction and use.

Also, due to the thermal bridge factor, the thermal insulation performance of the wall is affected
