[0007] The fasteners connecting the support include a screw and a nut; the screw is welded to the lower end of the support panel.

[0008] The bottom beam is vertically arranged between two steel structure main beams, and the top beam is parallel to the steel structure main beams.

[0009] The two ends of the bottom beam are connected to the vertical connecting plates of the connecting support by bolts.

[0010] The bottom beam is a U-shaped beam.

[0011] The top beam is a U-shaped beam.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model discloses a steel structure composite floor deck return bracket, which fully utilizes the existing conditions of the steel structure frame, fixes the bottom beam of the bracket by connecting the support on the wing plate, reduces the cost and improves the construction efficiency, and at the same time strengthens the stability of the bracket system, and prevents the bracket from moving under the action of wind load and overturning as a whole.

DETAILED DESCRIPTION

[0020] The utility model is described in detail below in conjunction with the accompanying drawings:

[0021] like Figure 1 As shown, the utility model is a steel structure composite floor decking top-returning bracket 100, which is used for the top-returning of the composite floor decking 200. The structure of the steel structure composite floor decking top-returning bracket 100 is shown in FIG. Figure 2-Figure 5, including a bottom beam 1, a connecting support 2, a vertical base pipe 3, a vertical support pipe 4, a top support 5 and a top beam 6; the connecting support 2 includes a support panel 21, a support bottom plate 22 and a fastener 24, the support bottom plate 22 and the support panel 21 are respectively located on the upper and lower sides of the lower flange plate of the steel structure main beam 300, and the support panel 21 and the support bottom plate 22 are connected to the lower flange plate through the fastener 24; a vertical connecting plate 23 is arranged on the support panel 21, and the two ends of the bottom beam 1 are respectively fixed It is fixed on a vertical connecting plate 23 of a connecting support; the vertical base pipe 3 is arranged in the middle of the bottom beam 1; the vertical support pipe 4 is rotatably arranged in the vertical base pipe 3; the top support 5 is threadedly connected to the vertical support pipe 4, and a horizontal rod 7 for rotating the vertical support pipe 4 is arranged on the vertical support pipe 4, and the length of the threaded joint between the vertical support pipe 4 and the top support 5 is adjusted by rotating the horizontal rod 7; the top beam 6 is arranged on the top support 5 for returning the composite floor decking 200.
