[0018] It should be noted that in the description of this specification, the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. The cantilever steel beam and the connecting beam can be arranged orthogonally or obliquely, and this embodiment takes the orthogonal arrangement as an example.

[0019] As shown in the figure, an embodiment of the utility model discloses a fixing device for cantilever steel beams, including a connecting assembly for connecting the cantilever steel beam 6 and the coupling beam and an anti-skid assembly installed on the cantilever steel beam 6 and / or the coupling beam, wherein the connecting assembly includes a connecting clamp 5 and a pressure plate 4, the connecting clamp 5 is sleeved on the cantilever steel beam 6 and the coupling beam, and the pressure plate 4 is detachably installed on the end of the connecting clamp 5 to form a clamping fixation for the cantilever steel beam 6 and the coupling beam; the anti-skid assembly includes an anti-skid column 2, and the anti-skid column 2 is detachably installed on the cantilever steel beam 6 and / or the coupling beam. The detachable installation of the anti-skid column 2 on the cantilever steel beam 6 and / or the coupling beam corresponds to the installation of the anti-skid assembly on the cantilever steel beam 6 and / or the coupling beam, which means that the anti-skid assembly as a whole can be installed on the cantilever steel beam 6 or the coupling beam, and can be installed on the cantilever steel beam 6 and the coupling beam at the same time. In the absence of a connecting beam, the anti-skid assembly is only installed on the cantilever steel beam 6, and the anti-skid column 2 in the assembly provides a mounting point for the scaffolding poles on the cantilever steel beam 6; if there is a connecting beam, the anti-skid assembly is set according to the specific layout of the scaffolding.

This is understandable to technicians in this technical field and will not be repeated here. It should be noted that for the sake of ease of display, this embodiment takes the case where the scaffolding poles only fall on the cantilever steel beam 6 as an example, so there is no anti-skid assembly on the connecting beam.

The anti-skid seat 1 is clamped to the cantilevered steel beam 6 or the connecting beam through the clamping piece 10, and the clamping connection is fast and convenient for easy disassembly and assembly. The clamping to the cantilevered steel beam 6 or the connecting beam here is for a single anti-skid assembly, and each anti-skid assembly can only be installed in one position, and the anti-skid assembly mentioned above is installed on the cantilevered steel beam 6 and / or the connecting beam for the entire structure, that is, there will be a situation where multiple anti-skid assemblies exist, so it is installed on the cantilevered steel beam 6 and / or the connecting beam, which is understandable to technicians in this technical field and will not be repeated here.

[0021] In this embodiment, the clamping piece 10 and the anti-slip seat 1 are arranged at an angle so that the clamping piece 10 and the anti-slip seat 1 are in a hook-shaped structure as a whole.

As shown in the figure, the connection snap ring 5 in this embodiment is "U"-shaped, and has two ends as shown in the figure, that is, the two ends of the "U"-shaped connection snap ring 5. When in use, the connection snap ring 5 is sequentially sleeved on the cantilever steel beam 6 and the connecting beam to be connected from bottom to top, and then the pressure plate 4 is installed and fastened with the second fastener 8, so that the connection snap ring 5 and the pressure plate 4 firmly clamp and limit the cantilever steel beam 6 and the connecting beam, so that the cantilever steel beam 6 and the connecting beam form a detachable connection.

[0024] In this embodiment, at least two second fasteners 8 are provided, and both ends of the "U" shape of the connecting snap ring 5 are provided with external threads.
