Detailed Description

In order to make the technical problems, technical methods and advantages of the present invention more clear, the present invention will be further described in detail with reference to the embodiments of the present invention and the accompanying drawings; it should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in figures 1, 2 and 3, the steel beam mounting and positioning device provided by the embodiment has two groups, and the parts comprise a U-shaped fixing plate (101), a positioning clamping plate (102) and a fastening screw rod (103). The positioning clamp plate (102) is positioned in the middle of the U-shaped fixing plate (101), one side of the U-shaped fixing plate (101) is provided with a hole with threads, and the threads in the hole are matched with the threads of the fastening screw (103); the fastening screw (103) penetrates through a threaded hole of the U-shaped fixing plate (101) through rotation; one end of the fastening screw rod (103) is provided with a rotating handle, and the other end of the fastening screw rod is connected with the positioning clamping plate (102) and can rotate freely; the distance between the positioning clamping plate (102) and the U-shaped fixing plate (101) can be adjusted by rotating a handle on the fastening screw rod (103).

As can be understood by those skilled in the art, after the height of the top surface of the sliding block (302) of the device is determined by calculating the installation relative position relationship of the steel beam (500) and the steel column (400), the gap between the U-shaped fixing plate (101) and the positioning clamping plate (102) is installed at the flange plate position of the steel column (400), and the gap between the U-shaped fixing plate (101) and the positioning clamping plate (102) is reduced by rotating the rotating handle on the fastening screw rod (103), so that the device is finally clamped on the wing plate of the steel column (400), and a large friction force is generated between the device and the steel column (400), thereby installing and fixing the device on the steel column (400). The device meets the installation and fixation requirements.

Furthermore, both ends of the supporting plate (201) are respectively and fixedly installed on the U-shaped fixing plate (101) and the supporting base (301) and can provide support for the steel beam positioning unit (300).
