[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0017] The concrete pouring device for the steel structure column foot of this embodiment includes a trapezoidal funnel 2, the four sides of which are all trapezoidal, the upper opening of the trapezoidal funnel 2 is larger than the lower opening, and the trapezoidal funnel 2 surrounds the steel structure column 1. Concrete is poured into the column foot template supported at the bottom of the steel structure column 1 through the trapezoidal funnel 2, as shown in the attached Figure 1 As shown, attached Figure 1 The column foot template at the bottom is not drawn. The trapezoidal funnel 2 is composed of two symmetrical left and right parts, the joint is a right-angle side, and a splicing angle iron 3 is welded at the right-angle side of the splicing. The two splicing angle irons 3 are provided with corresponding circular holes 4 from top to bottom. The two splicing angle irons 3 of the left and right parts are fixed together by pins passing through the circular holes 4, so as to splice and form the trapezoidal funnel 2. In order to further strengthen the trapezoidal funnel 2, preferably, a top angle iron 7 is welded outwardly from the top edge of the trapezoidal funnel 2, and the top surface of the top angle iron 7 extends outward.

[0018] A bottom angle iron 5 is provided at the bottom edge of the trapezoidal funnel 2, and the bottom angle iron 5 is welded to the outer wall of the trapezoidal funnel 2, wherein the bottom surface of the bottom angle iron 5 is a horizontal plane, and the bottom surface of the bottom angle iron 5 extends horizontally into the trapezoidal funnel 2, and the bottom surface of the bottom angle iron 5 extends into the trapezoidal funnel 2 until it is flush with the inner side wall of the column base template supported at the bottom of the steel structure column 1, so that the lower end opening size of the trapezoidal funnel 2 is consistent with the opening surrounded by the column base template.

[0019] Long screws 6 are provided on the other two side surfaces of the trapezoidal funnel 2. The other two side surfaces refer to the remaining two side surfaces except the two side surfaces where the splicing angle irons 3 are located, that is, the two side surfaces where the non-splicing parts are located. The long screw 6 is threadedly connected to the trapezoidal funnel 2. In order to strengthen the connection, preferably, a threaded block 9 is welded on the inner wall of the trapezoidal funnel 2. The threaded block 9 is provided with an internal threaded hole. The long screw 6 passes through the trapezoidal funnel 2 and is threadedly connected to the threaded block 9 inward. The long screw 6 passes through the trapezoidal funnel 2 horizontally and can abut against the outer surface of the steel structure column 1 inward. The long screw 6 is used to tighten the steel structure column 1 so that the trapezoidal funnel 2 is fixed on the steel structure column 1. In order to increase the abutment area, it is preferred that the long screw 6 is welded with a circular piece 8 toward the inner end of the trapezoidal funnel 2. In this embodiment, one long screw 6 is provided at the top and one at the bottom.

[0020] When in use, after the column base formwork of the bottom steel structure column 1 is set up, the left and right parts of the trapezoidal funnel 2 are placed on the upper surface of the column base formwork for splicing, the inner edge of the bottom angle iron 5 of the trapezoidal funnel 2 is aligned with the inner wall of the column base formwork, and then the corresponding splicing angle irons 3 of the left and right parts are aligned, and the left and right parts are fixed together by pins to splice into a trapezoidal funnel 2, and then the long screw 6 is screwed inward so that the upper and lower long screws 6 are both pressed against the outer surface of the steel structure column 1, and finally concrete is poured into the column base formwork through the trapezoidal funnel 2.
