Description

Technical Field

[0001] The invention relates to the field of prefabricated thermal insulation wall panels, and more specifically, to a connector, a sandwich thermal insulation wall panel containing the connector, and a manufacturing method thereof. Background Art

[0002] In recent years, my country's prefabricated buildings have developed rapidly, and various new structural systems have flourished, mostly based on solid prefabricated structures. However, many problems have been found in practice, such as the low degree of automation in component production caused by the side reinforcement of prefabricated components, the difficulty in quality control caused by on-site steel bar connection, the large tower crane model, the difficulty in on-site lifting and transportation caused by the heavy weight of components, the large amount of formwork and steel bar operations caused by the connection of post-cast strips, and the large labor demand. In this context, the assembled integral composite shear wall structure came into being, and the integration of thermal insulation and decoration is also a major direction for the country to promote the development of prefabricated buildings.

[0003] Due to its special hollow prefabricated structure and flipping production process, the insulation connectors of sandwich insulation composite shear walls have high requirements on length and mechanical properties. At present, the cost of insulation connectors accounts for too high a proportion of the total cost of sandwich insulation composite shear walls, and the cost of insulation connectors is too high. There are no insulation connectors on the market that are truly suitable for the automated production of sandwich insulation composite shear wall panels in factories. Summary of the invention

[0004] In order to solve at least one of the problems existing in the above-mentioned prior art, the present invention provides a connector, a sandwich insulation wall panel containing the same and a manufacturing method thereof. They can meet the requirements of the wall for the length and mechanical properties of the connector. The special structure of the connector can increase the degree of automation in the production of the composite wall panel, and also serve as a wall panel thickness limiter, greatly simplifying the production process. The connector adopts a plane truss form, and the force transmission path is clear. At the same time, the gap between the horizontal rod and the vertical rod is conducive to the concrete pouring in the cavity of the sandwich insulation composite shear wall.

[0005] According to one aspect of the present invention, there is provided a connector for a sandwich insulation wall, the connector comprising: at least two horizontal rods; at least two vertical rods, one of the at least two vertical rods is the outermost vertical rod, and the other of the at least two vertical rods is the innermost vertical rod, wherein each of the at least two horizontal rods intersects perpendicularly with the at least two vertical rods respectively; and at least one diagonal rod, wherein at least two connection points of the horizontal rods and the vertical rods on a diagonal line are connected via the at least one diagonal rod.

[0009] Among them, the inner blade anchor steel bars are used as protective layer limiters for the inner blade steel cage.

[0010] Wherein, the horizontal rod is a wall thickness limiting device to control the total thickness of the sandwich insulation wall.

[0011] Wherein, the horizontal rods, vertical rods and diagonal rods are made of the following materials: any one of stainless steel, galvanized steel plates, and glass fiber reinforced resin.

[0012] The horizontal rods, vertical rods and diagonal rods are formed into a truss structure by, but not limited to, welding, mechanical connection or one-time forming to withstand the loads during the production, transportation and construction of the sandwich insulation wall.

[0013] According to another aspect of the present invention, there is provided a sandwich insulation wall panel, which comprises: a wall reinforcement cage; at least one of the above-mentioned connecting members inserted into the wall reinforcement cage; an inner concrete structure integrated with the innermost vertical rod of the connecting member; an outer concrete structure integrated with the outermost vertical rod of the connecting member; and an insulation board arranged between the outer concrete structure and the wall reinforcement cage.

[0014] Wherein, the sandwich insulation wall panel also includes an outer blade steel mesh, wherein the outer blade steel mesh is arranged on the outermost vertical rod of the connecting piece.

[0015] Wherein, the inner side of the connecting piece is fixed to the wall steel cage through the inner blade anchoring steel bar, and the outer side of the connecting piece is fixed to the outer blade steel mesh through the outer blade anchoring steel bar.

[0016] According to another aspect of the present invention, there is provided a method for manufacturing a sandwich insulation wall panel, the method comprising: placing a wall reinforcement cage on a formwork platform; inserting at least one of the above-mentioned connecting members into the wall reinforcement cage; pouring an inner concrete structure to become one with the innermost upright of the connecting member; arranging an insulation board between the outermost upright of the connecting member and the wall reinforcement cage; and pouring an outer concrete structure to become one with the outermost upright of the connecting member.

[0017] Wherein, the method further comprises setting the outer blade steel mesh on the outermost vertical pole of the connecting member.

[0020] Based on the above technical scheme of the present invention, the following beneficial effects are achieved: 1. Compared with the sheet-like thermal insulation connectors currently circulating in the market, materials are greatly saved; 2. The area of ​​penetration of the thermal insulation layer is small, thereby improving the thermal insulation performance of the wall; 3. The lateral stiffness of the thermal insulation connector is small, thereby reducing the adverse effects on the outer leaf plate due to temperature contraction and expansion; 4. The thermal insulation connector can also serve as a thickness limit device for the sandwich thermal insulation wall panel, and can also ensure that the steel cage and the mesh are in the correct position, so that their distance from the concrete outer skin on both sides is accurate.

In a preferred embodiment, the length of each horizontal rod is the same, and the length of each vertical rod is the same.
