Embodiment

[0035] Under normal circumstances, the construction of the large U-shaped steel frame external wall will start after the construction of the main structure is completed. Firstly, install the external wall slab, and connect the external wall slab to the main body by bolts through connecting ears or connectors as required. Then push into the silicone weather-resistant glue 16 at the U-shaped steel frame position between the two outer wall slabs. Reserve the benzene board grooves for the two external wall slabs during prefabrication, paste a benzene board during construction, paste glass fiber mesh cloth on the outside of the benzene board, and finally spray waterproof mortar, the steel frame is inside the benzene board, and the benzene board acts as a break Bridge role.

Abstract

The invention discloses a steel frame whole exterior wall board. The exterior wall board is in a square structure encircled by a U-shaped steel frame. The exterior wall board is formed by the following steps: sequentially fixing galvanized steel wire netting, reinforcing bar inner ribs and reinforcing bar trusses in the U-shaped steel frame; pouring EPS foamed concrete to fixedly connect the galvanized steel wire netting, reinforcing bar inner ribs and reinforcing bar trusses into a whole in the U-shaped steel frame; finally, laying an upper steel wire netting layer, forming a board blank after initial set of concrete, spraying waterproof mortar on two sides of the board blank and forming a wall; cutting an XPS board into the same size as the wall, and adhering the board to the wall by virtue of gluing, wherein a pressurized cement board is arranged on the outer side of the XPS board so as to form the exterior wall board. According to the U-shaped groove bridge-cutoff technology, only a single side of the steel frame is contacted with the surface layer, the other end is embedded inside a thermal insulation material, a cold-thermal bridge phenomenon is effectively avoided, and the thermal insulation effect of the whole exterior wall is improved. The building operations are reduced, and the building assembly rate is improved.

Description

technical field [0001] The patent of the present invention relates to a steel frame whole outer wall slab, which belongs to the technical field of building materials. Background technique [0002] The existing exterior wall panels have a single shape, a large amount of on-site construction, and high overall cost. In addition, the steel frame of the exterior wall is easy to dissipate heat. In winter, when encountering cold outdoor air, there is no heat preservation and condensation is easy to occur. [0003] In short, a new type of large slab prefabricates the entire exterior wall in the factory, and only needs to be easily hung on site. The method of composite XPS board after using U-shaped grooves on the board surface blocks the cold bridge of the steel frame, enhances the overall thermal insulation performance of the board surface, and avoids the phenomenon of condensation. Contents of the invention [0004] In order to solve the problems in the prior art, the present ...
