Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation blocks, in particular to a high-strength recycled aggregate concrete composite thermal insulation block based on construction waste. Background Art

[0002] Insulation blocks are building materials with good thermal insulation capabilities. Construction waste can be crushed and mixed with cement to produce secondary concrete. The strength of concrete produced from construction waste is generally low, and the insulation blocks generally have holes inside that retain air, causing the strength of the recycled aggregate concrete insulation blocks to be further reduced.

[0003] The defects of existing recycled concrete insulation blocks are: 1. The prior art EP0606625A3 discloses hollow bricks, which do not have a structure to enhance the strength of the hollow bricks. The hollow bricks have relatively low strength due to the presence of pores. Therefore, a high-strength recycled aggregate concrete composite insulating building block based on construction waste with enhanced concrete strength is needed to solve this problem.

[0004] 2. The prior art US20110047924A1 discloses hollow bricks for providing thermal insulation. However, this technology does not have a structure to prevent water seepage in the hollow bricks. When water seeps through the hollow bricks, the water will be transferred between the multiple hollow bricks, thereby causing the thermal insulation capacity of the hollow bricks to deteriorate. Therefore, a high-strength recycled aggregate concrete composite insulating block that prevents water from permeating between the multiple hollow bricks is needed to solve this problem.

[0005] 3. The prior art US20110239570A1 discloses a concrete hollow brick. This technology does not have a structure to prevent two adjacent hollow bricks from sliding against each other. When the hollow brick wall is hit, the hollow bricks can easily slide against each other, causing the wall to collapse. Therefore, a high-strength recycled aggregate concrete composite insulation block based on construction waste that can prevent the hollow bricks from sliding against each other is needed to solve this problem.

[0006] 4. The prior art CN104326764B discloses environmentally friendly hollow bricks. This technology does not have a structure that increases the sound insulation capacity. When there are large holes between the hollow bricks, although the thermal insulation capacity is increased, the quality becomes lower, but the sound insulation capacity of the hollow bricks becomes worse. Therefore, a high-strength recycled aggregate concrete composite insulating building block based on construction waste that improves the sound insulation capacity of hollow bricks is needed to solve this problem.

[0021] The present invention can reduce the poor sound insulation ability of the building block body caused by the hollowness by arranging the sound insulation cotton block. BRIEF DESCRIPTION OF THE DRAWINGS
