Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a large-span steel structure truss transfer layer fixing device. Background Art

[0002] With the development of social civilization and the emergence of new materials, new structures and new technologies, the application of steel structures is becoming more and more extensive, and the application of trusses is also becoming more and more extensive. The functions and structures of large-span steel structure buildings are becoming more and more complex, which poses a huge challenge to the traditional steel structure transfer layer construction technology. In the traditional steel structure transfer layer construction process, most of the transfer layers are fixed to the lower part of the truss by means of hanger welding. Taking the Anhui Sino-German (Suixi) International Cooperation Aluminum-based Industrial Park EPC project as an example, it consists of a 3-story convention and exhibition center and a 19-story hotel, with a basement. The 3-story convention and exhibition center has a large span and the truss transfer layer is high. The traditional hanger welding fixation method cannot meet the service life requirements, and it will shake when there is wind, which poses a safety hazard. In order to ensure the stability and safety of the truss transfer layer in the case of large-span steel structures, reduce safety hazards and reduce construction cost investment, a large-span steel structure truss transfer layer fixing device is proposed on the premise of meeting the stability and quality of the overall structure of the transfer layer.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The utility model uses a truss clamp to detachably install the transfer layer pedestal on the truss, thereby realizing the connection between the large-span steel structure truss and the upper and lower parts of the transfer layer, effectively ensuring the connection and fixing quality of the upper and lower parts and the overall stability, and ensuring the completeness of the truss. It not only provides a fixing point for the transfer layer pedestal, but also provides a stable attachment platform for the transfer layer, so that it will not be shaken by wind, thereby increasing the service life, ensuring safety in use, reducing cost investment, accelerating construction progress, and saving construction time.

[0008] Further, the preferred solution adopted in this utility is:

[0009] The truss clamp includes an upper clamp and a lower clamp, each of which is an arc-shaped structure. Both ends of the upper clamp and the lower clamp are respectively provided with fixed ends, and through holes are opened on the fixed ends. The upper clamp and the lower clamp are connected into a whole by a bolt assembly placed in the through holes.

[0010] A foundation connection plate is arranged on the top of the transfer layer foundation, and the foundation connection plate is connected to the lower clamp through a connecting frame.

[0011] The connecting frame comprises an upper connecting frame and a lower connecting frame, wherein the upper connecting frame is fixedly connected to the bottom of the lower clamp, and the lower connecting frame is fixedly connected to the base connecting plate, and the upper connecting frame and the lower connecting frame are connected by a bolt assembly.
