Prefabricated external wall

Abstract

The invention relates to a prefabricated external wall. The prefabricated external wall comprises a main steel structure (4) and a corbel (5), the corbel (5) comprises a cantilever member (6), steel plate connecting pieces (7), L-shaped connecting pieces (8) and stiffening plates (9); each L-shaped connecting piece (8) comprises a vertical plate and a supporting plate, and the vertical plate and the supporting plate are connected vertically and fixedly; each L-shaped connecting piece (8) is provided with two up-down back facing structures; the stiffening plates (9) are arranged in the middle of the inner side of each L-shaped connecting piece (8); the vertical plates of the two L-shaped connecting pieces (8) are fixedly connected with the steel plate connecting pieces (7) through bolts; the steel plate connecting pieces (7) are fixedly connected with the cantilever member (6) in a welded mode; the cantilever member (6) is connected with the main steel structure (4) in a welded mode; and L-shaped connecting piece gaps (10) are arranged between the supporting plates of the two L-shaped connecting pieces (8). According to the prefabricated external wall, it is guaranteed that the main steel structure is in the range of inter-story displacement and is adapted to the inter-story displacement requirement of a whole building.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a prefabricated outer wall. Background technique [0002] The Chinese invention patent with the patent number ZL201410157402.2 discloses a new type of prefabricated wall panel and the building exterior wall assembled from it. The new prefabricated wallboard includes a wallboard steel skeleton, and the wallboard steel skeleton includes main ribs, auxiliary ribs and reinforcing ribs; the auxiliary ribs are perpendicular to the main ribs, and the two ends of the auxiliary ribs are respectively connected to the upper and lower main ribs Both ends of the reinforcing ribs are connected with the main ribs and the auxiliary ribs; panels are installed on both sides of the steel frame of the wall panel, an insulation layer is installed between the panels, and a core material is installed on the insulation layer. This invention provides a new type of prefabricated wall panel and the buil...

Problems solved by technology

However, the support structure of this invention is complicated, that is, the support 10 must be assembled with the corner protector 12 to form the overall structure of the support. Although it can meet the interlayer displacement requirements of the steel structure building enclosure plates with a height of 27 meters or less, However, it is not suitable for the interstory displacement requirements of high-rise or super high-rise steel structure buildings.
