Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to the connection technology of thermally broken composite blocks. Background Technology

[0002] With the increasing national requirements for building energy conservation, the thickness of thermal insulation materials is gradually increasing. While improving insulation performance, the lifespan of the insulation material must be the same as that of the structure. The widespread adoption of sandwich insulation with thermal break structures is a major technical measure. Thermally broken composite blocks have advantages such as good insulation performance, high fire resistance, and excellent durability. Connectors for thermally broken composite blocks are key components that ensure the inner leaf blocks, insulation layer, and outer leaf blocks form a unified whole. Currently, the commonly used structures are those that bond the inner and outer leaf blocks to the insulation material, or those that combine bonding with anchor bolts. These structures suffer from drawbacks such as poor adhesive strength and reliance on the strength of the insulation material for easy detachment. Currently widely used truss-type connectors, rod-shaped connectors, and irregularly shaped (cylindrical or C-shaped) connectors all suffer from inaccurate connection positioning, large gaps, and the need for secondary construction, resulting in large gaps in both the vertical and horizontal directions, which can easily lead to cracks in the wall. Summary of the Invention

[0003] The purpose of this invention is to accurately, tightly, and reliably connect the inner and outer blades of the thermally broken composite block through dovetail grooves, so as to make the inner and outer blades of the thermally broken composite block and the intermediate insulation material into a whole. This overcomes the shortcomings of the current sandwich insulation structure, such as loosening, cracking, and low connection strength of the inner and outer blades, and achieves high connection strength, accurate dimensions, and the same lifespan as the building.

[0004] This utility model is a dovetail groove type thermal insulation composite block connector with guide wing positioning piece, including inner blade block 21 and outer blade block 22 of thermal insulation composite block. The inner dovetail piece 3 with inner dovetail guide wing 1 and inner dovetail positioning piece 2 is connected to the outer dovetail piece 10 with outer dovetail guide wing 8 and outer dovetail positioning piece 9 through the intermediate connecting piece 7 with transverse reinforcing rib 4, longitudinal reinforcing rib 6 and intermediate hole 5.

[0005] The beneficial effects of this utility model are as follows:

[0006] 1. The inner dovetail plate 3 has an inner dovetail plate guide wing 1 and an inner dovetail plate positioning piece 2; the outer dovetail plate 10 has an outer dovetail plate guide wing 8 and an outer dovetail plate positioning piece 9, so that the connector and the inner and outer blades of the thermal insulation composite block are tightly, reliably, and with high precision, and the inner and outer blades have strong bonding force, forming an integral structure.

[0007] 2. The intermediate hole 5 on the intermediate connecting piece 7 has a transverse reinforcing rib 4 and a longitudinal reinforcing rib 6. Due to the intermediate hole 5, the amount of steel used is reduced. At the same time, during the subsequent injection molding process, the insulation material can improve the insulation performance and strength by passing through the intermediate hole.

[0008] 3. The intermediate hole 5 on the intermediate connecting piece 7 has a transverse reinforcing rib 4 and a longitudinal reinforcing rib 6, which increases the strength of the intermediate hole and saves materials. Attached Figure Description
