Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a combined thermal insulation anchor structure. Background Art

[0002] At present, the outer walls of prefabricated buildings mostly use prefabricated concrete sandwich insulation walls to achieve integrated wall insulation and heat insulation. The sandwich insulation wall is divided into inner leaf wall, insulation board and outer leaf board, and the inner and outer leaves are usually connected by insulation anchors. However, at local connection locations, such as the cast-in-place section between prefabricated inner leaf walls, since the anchors extend out of the insulation part, they often conflict with the cast-in-place steel bars, making it difficult to tie the steel bars on site. In addition, since the insulation anchors here are exposed to the outside, there is a risk of the insulation anchors breaking during the transportation and hoisting of the prefabricated wall.

[0003] In order to solve the above problems, it is urgent to develop a combined thermal insulation anchor method that can facilitate on-site construction and ensure the quality of building construction. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides a combined thermal insulation anchor structure.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A combined thermal insulation anchor structure comprises a thermal insulation anchor nut, a thermal insulation anchor screw, a thermal insulation board, an outer blade plate, and a cast-in-place steel bar; the outer blade plate is fixed to the periphery of the thermal insulation board to form an integral precast concrete component; the thermal insulation anchor nuts are evenly spaced on the formed precast concrete component; concrete is poured on the cast-in-place steel bar to form a cast-in-place section as a whole; thermal insulation anchor screws are evenly spaced in the cast-in-place section corresponding to the thermal insulation anchor nuts, one end of the thermal insulation anchor screw is rotatably fixed in the cast-in-place section through a bearing sleeve; the thermal insulation anchor screw is screwed into the thermal insulation anchor nut to form a combined thermal insulation anchor, and the precast concrete component is connected to the cast-in-place section as a whole through the combined thermal insulation anchor.

[0007] As a further improvement of this solution, the combined thermal insulation anchor is in the shape of a rod.

[0008] As a further improvement of the present solution, the combined thermal insulation anchor is made of glass fiber rods.

[0009] As a further improvement of the present solution, both ends of the combined thermal insulation anchor are anchored in the precast concrete member and the cast-in-place section with an anchoring length of 35 mm.

[0010] As a further improvement of the present solution, the total length of the combined thermal insulation anchor is 35 mm + the thickness of the thermal insulation layer + 35 mm.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model solves the problems in the existing prefabricated buildings, such as the tension piece extending out of the insulation part and conflicting with the cast-in-place steel bars, which leads to difficulties in on-site steel bar binding and the tension piece being easily damaged and falling off. The combined thermal insulation tension piece of the present application includes a thermal insulation tension piece screw and a nut, and the screw and the nut can be connected by a thread. The thermal insulation tension piece nut is prefabricated as a concrete component with the insulation board and the outer blade as a whole. After the steel bars of the cast-in-place section are tied, the thermal insulation tension piece screw is screwed into the nut to form a combined thermal insulation tension piece, so that the prefabricated concrete component is connected to the cast-in-place section as a whole. During the construction of prefabricated buildings, the utility model can improve the construction efficiency, reduce the damage and falling of the tension pieces, and ensure the construction quality of the connection parts.
