Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a novel lightweight roof connection structure based on steel structures. Background Art

[0002] Prefabricated steel structure buildings are driving the rapid development of the construction industry because of their advantages such as easy installation, fast construction speed, saving construction time and construction costs, and resource recycling. It is a green and environmentally friendly building structure model and is the research direction for my country to achieve industrial development in the future. A steel structure is built on the roof, and then lightweight roof panels are installed on the steel structure.

[0003] According to Chinese patent application number 202221601535.0, a novel lightweight roof connection structure based on a steel structure is disclosed, comprising a plane purlin, one side of which is fixedly connected to a slope purlin, the upper end of which is fixedly connected to a roof panel mounting frame, one side of which is fixedly connected to a pair of T-shaped connecting blocks, one end of which is fixedly connected to a reinforcement rod, the end of the reinforcement rod away from the T-shaped connecting block is fixedly connected to the plane purlin, and the plane purlin, slope purlin and reinforcement rod cooperate to form a triangular area. A square hole is provided on one side of the slope purlin, and a reinforcing rod is passed through the inner cavity of the square hole. Both ends of the reinforcing rod are fixedly connected to force rods. On the one hand, the T-shaped connecting block and the reinforcing rod can share the force of the connection node between the plane purlin and the slope purlin, so that the connection node is not prone to deformation and damage. On the other hand, it can improve the stability of the connection between the plane purlin and the slope purlin. The slope purlins form a whole through the reinforcing rod and directly act on the roof through the force rod. On the one hand, the overall stability of the slope purlin is improved, and on the other hand, the force of the connection node between the plane purlin and the slope purlin can be shared again.

[0004] The above solution solves the following problems: 1. The existing roof connection structure has a relatively concentrated force on the connection nodes of the steel structure. When in use, if there is snow accumulation on the surface of the lightweight roof panel, it is easy to cause deformation and damage to the connection nodes; 2. The existing roof connection structure has poor overall stability and is not easy to install quickly. However, most of the above-mentioned structures are fixed with screws. However, due to their large size, they need to be disassembled for packaging and transportation, which is too cumbersome and inconvenient to transport. Therefore, we provide a new lightweight roof connection structure based on steel structure to solve the above problems. Utility Model Content
