Description

A connection structure of inner and outer leaf walls of sandwich thermal insulation outer wall panels

technical field

The invention relates to an inner and outer leaf wall structure of an exterior wall panel, in particular to a connection structure of an inner and outer leaf wall of a sandwich thermal insulation exterior wall panel.

Background technique

Energy saving and emission reduction is the basic national policy of our country. Instead of the traditional cast-in-place structure construction method, the industrial construction method of prefabricated components manufactured in the factory and assembled on site has been gradually promoted. At present, thermal insulation in the northern region mainly adopts external thermal insulation technology. External thermal insulation walls have fire protection and durability problems, and external thermal insulation is not suitable for direct prefabrication in factories. Prefabricated sandwich wall panels are mainly used in prefabricated buildings.

The connection technology of sandwich wall panels is the key technology to connect the inner and outer wall panels as a whole. The connector is mainly to bear the weight of the outer leaf wall panel and the shear force generated by the temperature effect. At present, the connectors of prefabricated sandwich insulation exterior wall panels used in China mainly use metal lattice steel bars, stainless steel connectors from HALFEN in Germany and THERMOMASS connectors. Metal lattice steel bars have poor corrosion resistance, and stainless steel connectors will have local thermal bridges. THERMOMASS connectors are carbon fiber connectors. The connection form is straight rods, and the ends use enlarged wedges. It is easy to crack at the point, and it is mainly suitable for the situation where the inner and outer leaf wall panels are thick. Glass fiber has good corrosion resistance, high bearing capacity and small thermal bridge effect. At present, the housing industry is developing in the direction of industrialization, and prefabricated buildings have begun to be promoted and applied nationwide. Therefore, the development of glass fiber reinforced connectors for sandwich wall panels with thinner outer leaf wall panels can promote the application range of prefabricated buildings, and the economic and social benefits are significant.

Contents of the invention

The invention is proposed in response to the above problems, and the purpose is to provide a sandwich insulation wallboard suitable for thinner exterior wallboards. Through the connectors with good anchoring performance, strong corrosion resistance and low thermal conductivity, low cost and overall stability can be achieved. Better, it is a connection structure between the inner and outer leaf walls of the sandwich thermal insulation outer wall panel which reduces resources and energy consumption.

In order to achieve the above object, the technical solution of the present invention to solve technical problems is:

A connection structure between the inner and outer leaf walls of sandwich thermal insulation outer wall panels, comprising: inner and outer leaf wall panels and insulation layers of the outer wall, an insulation layer is arranged between the inner and outer leaf wall panels of the outer wall, and the inner and outer leaf panels At least one additional anchoring steel bar is provided on the main bar of the wall panel, and a number of U-shaped glass fiber bars with hooks at the open ends are uniformly arranged at the matching positions of each edge of the outer wall; between at least two rows of U-shaped glass fiber bars and/or Or the middle part of the outer wall is provided with a suitable number of V-shaped glass fiber bars with hooks at the opening ends; the closed parts and hook parts of the U and V-shaped glass fiber bars are connected to the inner and outer bars respectively through the insulation layer. Additional anchoring reinforcement for leaf wall panels.

The insulation layer is extruded board.

The V-shaped opening angle of the V-shaped glass fiber reinforcement is one of 30° or 45°.

Compared with the prior art, the present invention has the following advantages and effects:

Because the present invention adopts U and V-shaped glass fiber bars with hooks at the open end as the inner and outer leaf wall panels connecting the outer wall with the sandwich insulation layer, the continuity of the components and the overall stability of the structure are guaranteed, and the bearing capacity is high. The thermal bridge effect is small, further reducing costs, reducing resources and energy consumption, effectively improving the overall quality of housing, and also improving labor productivity, making housing construction on the road of sustainable development, with good economic and social benefits.
