Energy-saving compound concrete self thermal insulation building block

Abstract

The invention discloses an energy-saving compound concrete self thermal insulation building block. The building block comprises a left half building block (1), a right half building block (3) and a thermal insulation block (4), wherein dovetail grooves (5) are formed on the inner sides of the left half building block (1) and the right half building block (3); dovetails (6) matched with the dovetail grooves (5) are formed on the two sides of the thermal insulation block (4); and the thermal insulation block (4) is positioned in the middle and is compounded with the left half building block (1) and the right half building block (3) through the dovetail grooves (5) and the dovetails (6) to form a three-in-one building block. The building block is energy-saving, utilizes waste, and has thermal insulation property, light weight and high strength, the thermal insulation block is connected with the left half building block and the right half building block through the dovetails and the dovetail grooves, the upper, lower, left and right parts of the thermal insulation block are occluded with one another through a convex edge and a groove to form a closed thermal insulation wall, and the wall has the function of completely isolating a cold bridge and saves energy by 65 percent.

Description

technical field [0001] The invention relates to blocks, in particular to an energy-saving composite concrete self-insulating block. Background technique [0002] As we all know, concrete self-insulation composite block is a kind of wall material with thermal insulation and heat insulation properties. The blocks currently on the market are small hollow concrete blocks with multiple rows of holes made of a single material. Filling with thermal insulation materials, increasing the thermal resistance of the block by increasing the thickness of the air interlayer alone has limited effect, and it is difficult to meet the requirement of 65% energy saving. If the number of holes is increased, the thickness of the block must be increased, which not only increases the The self-weight is not conducive to construction, but also increases the amount of materials. Contents of the invention [0003] The object of the present invention is to provide an energy-saving composite concrete se...
