[0017] As shown in the drawings, Figure 1 The steel bar 3 is generally provided with a plurality of protrusions on the surface, and the protrusions are arranged uniformly on both sides of the steel bar 3.

[0018] As shown in the drawings, Figure 2 , Figure 3As shown, for the shape of the reinforcing steel 3, the utility model provides a foundation embedded part for steel structure of viaduct, simple structure and easy to assemble, the utility model discloses a base 1, the support sleeve 2 of base 1 middle part, reinforcing steel 3, the both sides of base 1 are connected with the positioning mechanism 4 that is mirror image each other respectively, the positioning mechanism 4 includes support frame 41, a plurality of clamping seat 42 are arranged on the side of support frame 41 close to the center of base 1, clamping seat 42 includes the positioning plate 421 for clamping on the both sides of reinforcing steel 3, that is, two positioning plates 421 form the clamping groove of clamping seat 42, the folding edge 422 is arranged on the both ends of positioning plate 421.

[0019] Specifically, reinforcing steel 3 includes cylindrical body and surface protrusion, the folding edge 422 of positioning plate 421 is close to reinforcing steel 3 body, when clamping seat 42 has the tendency of moving up and down, the folding edge 422 is blocked by the surface protrusion of reinforcing steel 3.And the positioning mechanism 4 of both sides of base 1 is mirror image each other, that is, the clamping seat 42 of both sides of base 1 is mirror image each other, and since reinforcing steel can only enter clamping seat 42 from one side of clamping seat 42, the front and back and left and right movement of base 1 is limited, the connection of base 1 and reinforcing steel 3 is realized.The utility model discloses when using, reinforcing steel 3 is inserted into clamping seat 42 from the side of clamping seat 42, simple and convenient to use.

[0020] Further, the positioning mechanism 4 includes a fixed plate 43, the fixed plate 43 is fixedly connected with the base 1, and the fixed plate 43 is connected with the positioning frame by a bolt connection mode.

[0021] The utility model discloses when using, support frame 41 can be connected with reinforcing steel 3 first, then support frame 41 is connected with the fixed plate 43 on base 1, so that when the support seat and reinforcing steel 3 are connected, the base 1 is not blocked, and there is enough operation space, which is convenient for operation.

[0022] Further, the folding edge 422 close to the center of the base 1 is provided with a chamfer on one side, which facilitates the reinforcing steel 3 to enter the clamping seat 42 from the side of the clamping seat 42.

[0023] The above is only the preferred embodiment of the utility model, and is not other forms of the utility model, any skilled person in the art can change or modify the above disclosed technology content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the utility model to the above embodiments still belongs to the protection scope of the utility model technical scheme.
