As shown in fig. 1 to 5, the utility model provides a large steel corbel on concrete structure, which is characterized in that it includes:
an embedded device 1 including an embedded steel box and a plurality of pressure transmission members 14; the embedded steel box is formed by fixedly connecting a plurality of narrow steel boxes 11 with openings at one side in sequence, and the upper plane, the lower plane and the two parallel side surfaces of the embedded steel box are fixedly connected with a plurality of pressure transmission members 14;
the shearing device 2 comprises a plurality of webs 21 with I-shaped sections, one end of each web 21 can be correspondingly inserted into one narrow steel box 11, and supporting steel plates 22 are fixedly connected to the upper plane and the lower plane of the part, which is not inserted into the narrow steel box, of each web.
In the technical scheme, the pressure transmission members 14 are arranged in the horizontal direction and the vertical direction of the embedded steel box to increase the stress stability of the embedded steel box, and the pressure transmission members can be force transmission members such as reinforcing steel bars and steel plates. The embedded steel box is composed of a plurality of narrow steel boxes 11, the shearing resistant device 2 is correspondingly inserted into the narrow steel boxes 11 through a plurality of webs 21 to bear shearing force, and the shearing force is shared through the narrow steel boxes 11 and the webs 21, so that the stress capacity of the steel corbel is improved. The number of narrow steel boxes 11 and webs 21 required may also be determined according to the magnitude of the shear force. The web plate 21 can be designed into a steel plate with an I-shaped cross section, so that the stability of the web plate 21 inserted into the narrow steel box 11 can be improved, the downward transmission of the load borne by the upper end is facilitated, and the shearing resistance of the web plate 21 is further ensured.
In another embodiment, a pressure diffusion plate 13 is fixedly connected to the lower plane of the embedded steel box, a plurality of pressure transmission members 14 are fixedly connected to the lower plane of the pressure diffusion plate 13, and the number of the pressure transmission members 14 fixedly connected to the lower plane of the pressure diffusion plate 13 is greater than the number of the pressure transmission members 14 fixedly connected to the upper plane of the embedded steel box. The pressure diffusion plate 13 is used for assisting in downward diffusion and transmission of the pressure applied to the narrow steel box 11, so as to increase the stability of the narrow steel box 11 after being stressed.
In another embodiment, the pressure transmission members 14 fixedly connected to both side surfaces of the embedded steel box are symmetrically arranged. The pressure transmission members 14 on the two sides of the embedded steel box are used for diffusing and transmitting the stress of the embedded steel box in the horizontal direction and reversely providing horizontal support for the embedded steel box.
