Chiseling-free bolt type concrete intercepting device and using method thereof

The invention discloses a chiseling-free bolt type concrete intercepting device and a using method thereof, and belongs to the technical field of constructional engineering. The bolt cap is arranged at one end of the bolt pipe and is connected with the bolt pipe; the connecting pipe is provided with a sliding groove penetrating through the radial opposite faces, one end of the sliding groove is open, the bolt pipe is slidably connected with the sliding groove, and the bolt cap is arranged on the outer side of the sliding groove and abuts against the sliding groove; the fixing block is in a U shape, and the fixing block is connected with the connecting pipe in a clamped mode; a fixing plate is arranged on one side of the fixing block, and a semicircular hole rotationally connected with the bolt pipe is formed in the edge of the fixing plate. The backward method that a simple closing-in net is arranged on beam steel bars in the prior art is replaced, meanwhile, the process defect that beam column/wall joint stu
