Description

Technical Field

[0001] The invention relates to the technical field of building exterior wall thermal insulation, and in particular to a thermal insulation wall connection structure and a thermal insulation wall having the same. Background Art

[0002] Wall insulation is an important measure to achieve building energy conservation. The common method is to lay insulation boards on the outside of the building and fix the insulation boards by bonding and anchoring. However, as time goes by, the insulation boards often become hollow and fall off. In order to avoid the above problems, the technology of building insulation and structural integration has gradually emerged. This technology is to cast the insulation layer and the structural layer as one, so as to achieve a new type of building energy-saving technology that has the same lifespan as the wall and meets the fire protection requirements. Among them, the built-in insulation cast-in-place concrete system refers to a structural system in which the outer side is a concrete protective layer, the inner side is a concrete structural layer, the insulation layer is placed between the protective layer and the structural layer, and the inner and outer walls are connected by oblique plug-in wires. Since the oblique plug-in wires are metal parts, the thermal conductivity is large, which has a great influence on the thermal insulation performance of the wall, and the number of oblique plug-in wires is large, and the construction is complicated. For this reason, the prior art adopts a solution in which the inner layer is a rod body and the outer layer is a rod sleeve. However, in this structure, since the thermal conductivity of the ends of the rod body and the rod sleeve and the fixed structure of the wall is still large, the thermal insulation performance of the wall is not ideal. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the thermal conductivity coefficient of the connection structure for the insulation wall in the prior art is large, which affects the insulation performance, thereby providing an insulation wall connection structure that effectively reduces the formation of thermal bridges and has good insulation performance, and an insulation wall having the same.

[0004] In order to solve the above technical problems, the present invention provides a connection structure for a thermal insulation wall, comprising:

[0005] The inner rod comprises a first fixing portion and a second fixing portion respectively used for fixing to the inner side and the outer side of the thermal insulation wall, wherein the second fixing portion is provided with a hollow cavity.
