Thermal insulation board for composite thermal insulation building block

Abstract

The invention discloses a thermal insulation board for a composite thermal insulation building block. Both surfaces of the thermal insulation board are provided with dovetail grooves (1). Both ends of the thermal insulation board are respectively provided with one V-shaped groove (2). The thermal insulation board is characterized in that both the dovetail grooves (1) are of a structure with big groove bottoms and small rabbets; a convex part between the two dovetail grooves (1) is of a structure with a small upper part and a big lower part; the upper end of the convex part is parallel and level with the upper surface of the thermal insulation board; the bottom of the convex part is not communicated with the bottom of the thermal insulation board and a certain distance is reserved between the bottom of the convex part and the bottom of the thermal insulation board; the dovetail grooves (1) are of an inclined structure; and the upper end of each dovetail groove is wider than the lower end of the dovetail groove. According to the thermal insulation board for the composite thermal insulation building block, which is disclosed by the invention, the difficult problems of untight connection among an outer page layer, an inner page layer and an insulating layer of the building block and easiness for loosening of the outer page layer are effectively solved, the quality and the using effect of the composite thermal insulation building block are improved, and the safety of the transportation link and the masonry process is ensured. The thermal insulation board is suitable for a composite self-insulation concrete hollow block or brick.

Description

technical field [0001] The invention relates to building materials, in particular to concrete blocks, especially to components of composite thermal insulation blocks. Background technique [0002] The composite self-insulating concrete hollow block is composed of internal parts, thermal insulation materials and external parts. The internal parts and external parts are concrete parts, and the thermal insulation material is foamed resin. The concrete part clamps the thermal insulation material through the dovetail groove, so that the concrete part and Insulation material is combined. For this self-insulating concrete hollow block, the foam insulation boards used are all connected by non-tapered dovetail grooves. It is characterized in that the upper and lower widths of the dovetail groove are consistent, and the height of the dovetail groove is the same as the brick height. The connection between the outer part, inner part and insulation layer of the block in this connection ...

AI Technical Summary

Problems solved by technology

Obviously there is still the problem of insufficient connection, but so far there is no design of dovetail slots with different widths and heights at the top and bottom
