Description

Technical Field

[0001] This utility model relates to the field of building insulation materials technology, specifically to a lightweight composite hollow insulation block. Background Technology

[0002] With the continuous improvement of building energy efficiency standards, traditional wall materials can no longer meet the dual requirements of high-efficiency thermal insulation and structural safety. Existing lightweight composite thermal insulation blocks usually adopt an integral insulation layer design, that is, a continuous insulation material (such as polystyrene board, rock wool board, etc.) is directly laminated in the middle or on the surface of the block. However, this type of design has the following technical defects:

[0003] Insufficient integrity: The insulation layer covering the entire structure is prone to interface cracks due to the difference in material shrinkage rates between the insulation layer and the block matrix. Especially under alternating hot and cold conditions or external forces, the insulation layer is prone to detach from the blocks, resulting in damage to the structural integrity of the blocks and affecting the safety of the building.

[0004] To address the aforementioned issues, this application proposes a lightweight composite hollow thermal insulation block. By incorporating four independent grooves in the center of the block and filling them with separate thermal insulation blocks, the projection of the insulation blocks covers the entire vertical cross-section. This eliminates thermal bridging and enhances the overall integrity of the block through the interlocking structure of the grooves. Compared to traditional designs, this structure significantly improves crack resistance, structural stability, and construction adaptability while maintaining thermal insulation efficiency, thus possessing greater engineering application value. Utility Model Content

[0005] In view of the above-mentioned technical problems in related technologies, this utility model provides a lightweight composite hollow thermal insulation block that can solve the above problems.

[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0007] A lightweight composite hollow thermal insulation block includes thermal insulation blocks A, B, C, and D filled inside the block. Short grooves are provided on both the left and right sides of the block, and the two short grooves are horizontally aligned. Two long grooves of the same size are provided on the middle surface of the block, and the two long grooves are symmetrically arranged about the horizontal center line connecting the two short grooves. Thermal insulation blocks A and C are filled inside the short grooves, and thermal insulation blocks B and D are filled inside the long grooves. The short grooves and long grooves are not connected to each other.

[0008] Furthermore, the opposite surfaces of insulation blocks A and C overlap with those of insulation blocks B and D.

[0009] Furthermore, the upper and lower surfaces of insulation block A are integrally formed with boss A, the upper surface of insulation block B is integrally formed with boss B, and the lower surface of insulation block B is integrally formed with two bosses C. The two bosses C are symmetrically arranged about the vertical line of boss B.

[0010] Furthermore, two identical interlocking grooves are vertically formed on the left side of the block, and two identical insert strips are integrally formed on the right side of the block, with the interlocking grooves and insert strips horizontally aligned.

[0011] Furthermore, two through holes of the same size are opened in the middle of the block, and the two through holes are symmetrically arranged about the vertical line of the block.

[0012] The beneficial effects of this utility model are as follows: The device of this application sets four grooves in the middle of the block to fill the insulation block. The projection area of ​​the four insulation blocks can cover the vertical cross-section of the entire block, so that the block can achieve the insulation effect. The four grooves maintain the integrity of the block through structural design. Compared with the traditional composite block where the insulation layer is designed to cover the middle of the block, the composite block of this application has better overall integrity and firmness.
