Concrete interceptor for junction of in-situ cast vertical component and horizontal component

The utility model discloses a concrete interceptor for the junction of an in-situ cast vertical component and a horizontal component. An interception net is arranged in an opening of a vertical component mold plate on the junction of the vertical component and the horizontal component, and the interception net adopts a steel wire mesh of 3.0mm*10mm*10mm; a plurality of supporting reinforcing steel bars which are vertically arranged are arranged on the back surface of the interception net, the distance between two adjacent supporting reinforcing steel bars is less than or equal to 200mm, each supporting reinforcing steel bar is fixedly connected with the steel wire mesh by virtue of a steel wire in a binding manner, the supporting reinforcing steel bars and the steel wire meshes are fixedly connected with surface ribs and bottom ribs of the horizontal component which is intersected with the supporting reinforcing steel bars and the steel wire meshes by virtue of a steel wire in a binding manner. By adopting the concrete interceptor, the problems in the pouring construction that the thickness of the horizontal component is offset due to the surging of concrete, the surface flatness is poor, and the vertical component has defects such as escaping of concrete, honeycombs, rough surfaces, broken root parts, holes and the like can be solved, the structural integrity and the water resistance can be guaranteed, success in construction can be guaranteed, the waste of concrete material can be prevented, and the labor is saved. The concrete interceptor is simple in structure, convenient in construction, economical, practical and easy to popularize.
