Upper-and-down two-point type connecting joint of steel structure and polycarbonate (PC) outer wall

Abstract

The invention relates to an upper-and-down two-point type connecting joint of a steel structure and a polycarbonate (PC) outer wall. The PC outer wall is assembled vertically. A steel structure boundary beam is arranged on one side of the vertically-assembled PC outer wall. A first bracket is welded to one side of the steel structure boundary beam and located between the steel structure boundary beam and the PC outer wall. A connecting base is welded to the bracket and welded by a bearing plate and round steel, and the round steel is arranged vertically. A welding-stopping plate, a heel block, a positioning plate are inserted in the round steel in sequence from bottom to top, and the round steel is welded to the positioning plate. A pre-embedded part is pre-embedded at the lower part of the PC outer wall on the upper portion and welded to the positioning plate. A pre-embedded bolt is pre-embedded at the upper part of the PC outer wall on the lower portion. Connecting angle steel is correspondingly connected with the pre-embedded bolt and a second bracket. The second bracket is welded to one side of the steel structure boundary beam. According to the upper-and-down two-point type connecting joint of the steel structure and the PC outer wall, the firmness and safety of wall plate installing can be ensured, on-site installation construction errors can be adjusted as much as possible, and on-site actual construction requirements can be met.

Description

【Technical field】 [0001] The invention relates to a building structure, in particular to a connection node between an upper and lower two-point steel structure and a PC outer wall, and belongs to the technical field of building engineering. 【Background technique】 [0002] The development of prefabricated buildings is a major change in the way of construction. It is an important measure to promote the supply-side structural reform and the development of new urbanization. It is conducive to saving resources and energy, reducing construction pollution, improving labor production efficiency and quality and safety levels, and promoting construction. In-depth integration of industry and informatization industrialization, cultivation of new drivers of new industries, and promotion of the resolution of excess capacity. In recent years, my country has actively explored the development of prefabricated buildings, but most of the construction methods are still based on on-site pouring,...

Problems solved by technology

[0004] However, since all PC wall panels are prefabricated in the factory and assembled on site, although the prefabrication in the factory can guarantee the overall tolerance and accuracy of the wall panels, due to the complex construction on site, large deformation of the steel structure, structural settlement, and other factors, there will be serious problems in the on-site installation. Installation errors and the inability to accurately assemble the panels will cause delays in the construction period and increase in actual engineering costs, etc.

However, if the reserved installation error is too large, it will lead to problems such as the installation of the wall panel and the structure is not tight, not firm, etc.
