Description

TECHNICAL FIELD

[0001] The utility model relates to pipe truss technical field, concretely is a kind of built-in prestressed pipe truss structure. BACKGROUND

[0002] With the continuous growth of China's steel output, pipe truss is used more and more widely, and its proportion in construction is increasing. It is widely used in industrial plants, automobile industry equipment platforms, logistics storage, public buildings, business clubs, high-speed rail platforms, subway platforms, high-rise business buildings, etc. Steel pipe structure has made great breakthroughs. The biggest advantage of steel pipe structure is that it can perfectly combine the functional requirements, sensory requirements and economic benefits of buildings.

[0003] According to the Chinese patent with application number 202121697378.3, a built-in prestressed pipe truss structure is disclosed, which includes a pipe truss, a support frame and a fixed plate. The support frame has positioning blocks fixedly connected to the upper and lower ends of the outer side of one end near the center of the pipe truss. The positioning blocks are slidingly connected to the pipe truss. The inner side of the positioning block is spirally connected with a first threaded rod. The first threaded rod is spirally connected with the pipe truss. The inner side of the support frame is fixedly connected with a fixed block at the central position of the front and rear ends. The inner side of the fixed block is slidingly connected with a fixed rod. The inner side of the fixed rod is spirally connected with a second threaded rod. The second threaded rod is spirally connected with the fixed block. The inner side of the pipe truss is slidingly connected with a cable.

[0004] The above-mentioned scheme solves the problem that the pipe truss may have a certain risk of falling off after long-term use. After the support frame falls off, the pipe truss is weak in stress and is prone to breaking under stress. Moreover, during transportation, the pipe truss support may rub, and vibration may occur during transportation, which may cause the pipe truss to jump and increase the difficulty of transportation. However, the above-mentioned scheme only uses the first and second gaskets to protect the pipe truss from vibration during transportation. However, the shock-absorbing effect is generally poor, and some old transport vehicles have uneven surfaces. The above-mentioned scheme cannot adjust the flatness of the pipe truss in the transport vehicle, which may cause the pipe truss to jump and rub more easily when encountering small vibrations. Therefore, we provide a built-in prestressed pipe truss structure to solve the above problems. Utility model content
