[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Please refer to Figures 1-7 , the embodiment provides a kind of steel structure welding fixing equipment, including clamp 1, clamp 1 is set to two, and two clamps 1 are rotationally connected. Among them, clamp 1 includes base plate 2 and clamping plate 3, as shown in Figure 2 And Figure 3 , four corners of base plate 2 upper end are all fixedly connected with screw rod, and clamping plate 3 is provided with four through holes matched with screw rod, and screw rod on base plate 2 is slidably penetrated through the through hole of clamping plate 3, and the screw rod protruding from clamping plate 3 is threadedly connected with nut, and small steel member (small angle steel, channel steel or I-beam etc.) is placed between base plate 2 and clamping plate 3, and clamping plate 3 is slid down and adhered above steel member by gravity after loosening clamping plate 3, and steel member can be clamped and fixed between base plate 2 and clamping plate 3 by screwing nut.

[0025] As shown in Figure 1 , Figure 2 And Figure 3 , the side wall of base plate 2 is fixedly connected with connecting plate 21, one of the connecting plates 21 of base plate 2 is fixedly connected with screw rod, and the connecting plate 21 of the other base plate 2 is provided with through hole, and screw rod penetrates through the through hole, so that the two connecting plates 21 can be rotationally adjusted angle, that is, the angle between the two clamps 1 is adjusted, so that the two steel members clamped and fixed by clamp 1 can be connected at multiple angles. One end of screw rod protruding from the through hole is threadedly connected with nut, and the friction coefficient between the two connecting plates 21 can be increased by screwing the nut, and then the angle between the two connecting plates 21 is fixedly blocked.

[0026] However, it is found in actual operation that the steel member still moves between the base plate 2 and the clamping plate 3 when the clamp 1 clamps and fixes the steel member, in order to further fix the steel member, the clamping plate 3 is provided with a clamping mechanism 4. Figure 5 As shown in the figure, the clamping mechanism 4 comprises a sliding plate 41, a clamping tooth 42 and an adjusting rod 43, wherein the sliding plate 41 is provided in two, the clamping plate 3 is provided with a sliding groove, and the two sliding plates 41 are symmetrically arranged and slidably installed in the sliding groove.
