Description

Technical Field

[0001] The utility model relates to the technical field of steel structure buildings, in particular to a novel assembled purlin support plate structure. Background Art

[0002] Steel structure buildings have become the preferred structural form for my country's vigorous development of prefabricated buildings due to their advantages such as fast construction speed, quick installation, prefabricated installation, and industrialized production. Prefabricated steel structure buildings have significant technical advantages in the context of my country's building industrialization and green building development. At the same time, steel structure buildings have recycling value and are a green building structure with low-carbon and environmentally friendly architectural characteristics throughout the entire life cycle of the building.

[0003] The purlin support plate of steel structure building is a steel structure connector that connects the structural steel beam and the roof purlin. Its function is to connect the steel structure beam and the roof purlin, and can transfer the load of the roof purlin to the structural steel beam, increasing the integrity and stability of the structure. The position of the traditional purlin support plate is determined in the structural design stage, and the purlin support plate is welded to the steel structure beam on site. The high-altitude welding operation on site is difficult, and it is also very troublesome compared to the demolition of temporary buildings. The industrialization of prefabricated buildings is not high, especially when transporting to the site to install the purlins. During the installation process on site, the relative position deviation of the purlin support plate will occur, causing the purlin to deform and bend, affecting the safety of the building steel structure. The traditional steel structure purlin support is located above the steel structure beam. The structural roof composed of the purlin support and the steel structure beam is very high, which makes the indoor net height of the building relatively low and the building roof is not beautiful.

[0004] Therefore, developing a new type of assembled purlin support plate structure with reasonable assembly, simple structure and convenient production has important practical significance for saving economy, reducing the construction error of purlin support plate causing inaccurate purlin position, ensuring structural safety, and promoting the industrialization of modern buildings, standardization of assembly production, and low-carbon green buildings.

It is a purlin support plate structure with assembled construction, good force performance, simple structure, standardized factory production, and on-site installation. It can effectively solve the problems of purlin support plate position error caused by steel beam installation error, thereby causing purlin bending and deformation, unreliable safety, etc. The purlin support plates of the new assembled purlin support plate structure are fully bolted at the construction site, with efficient construction speed, green and low-carbon, and improve the application scope of assembled steel structure buildings.
