Prefabricated outer wall

Abstract

The invention relates to a prefabricated outer wall. The prefabricated outer wall comprises a main body structure (4), a bracket (5) and prefabricated outer wallboard steel frameworks (1), wherein oneend of the bracket (5) is connected with the main body structure (4), and the other end of the bracket (5) is connected with the prefabricated outer wallboard steel frameworks (1); the two side facesof each prefabricated outer wallboard steel framework (1) are provided with a prefabricated outer wallboard outer panel (2) and a prefabricated outer wallboard inner panel (11) respectively; the lengths of the four edges of each prefabricated outer wallboard outer panel (2) and the length of the four edges of each prefabricated outer wallboard inner panel (11) are 10-100 mm smaller than the outerside edges of the two prefabricated outer wallboard steel frameworks (1); water stop pads (3) are arranged at the gap between the two prefabricated outer wallboard steel frameworks (1) and between the prefabricated outer wallboard outer panels (2) and the prefabricated outer wallboard inner panels (11); strip pressing plates (12) are installed on the water stop pads (3). The prefabricated outer wall effectively overcomes the technical defect that rainwater permeates into plates or indoors through plate seams, thoroughly eliminates the rainwater leakage problem, and meanwhile meets the overallbuilding inter-story displacement requirement.

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, on the one hand, this invention does not provide a water-stop pad and batten at the gap between the steel skeletons of the two wall panels, so when it rains outside after installation, rainwater will leak into the interior of the panels or into the room through the cracks in the panels; On the other hand, the support structure of this invention is complicated, that is, the support must be assembled with the corner protectors to form the overall structure of the support, although it can meet the interstory displacement requirements of the steel structure building envelope with a height of less than 27 meters , but it is not suitable for the interstory displacement requirements of high-rise or super high-rise steel structure buildings
