The utility model discloses further set up to: the back of the precast block far away from the screw hole is aligned with the side face of the outer wall body.
Through adopting above-mentioned technical scheme, set up the back that the screw hole was kept away from to the prefabricated section and align with the side of outer wall for outer wall keeps leveling, reduces bellied edge to staff's fish tail, improves the security at scene.
The utility model discloses further set up to: the diameter of the back face, far away from the screw hole, of the precast block is larger than the aperture of the screw hole.
By adopting the technical scheme, the diameter of the back surface of the precast block, which is far away from the screw hole, is larger than the aperture of the screw hole, so that the precast block can be conveniently filled into the groove body, and the workload of workers is reduced; meanwhile, the prefabricated block is pressed tightly by a rubber hammer by workers, so that pretightening force is generated between the prefabricated block and the side wall of the groove body.
The utility model provides a supporting device in shutoff outer wall screw hole, includes cylindric connecting rod, the one end of connecting rod is connected with and is used for seting up the round platform drill bit of cell body.
By adopting the technical scheme, the sleeve and the concrete of the hole are ground to be smooth in a round table shape at one time through the round table type drill bit, the punching process is omitted, the working procedure is simple, and the operation and the construction are simple and convenient.
To sum up, the utility model discloses following beneficial effect has:
1. the circular truncated cone-shaped groove body is formed in the outer side of the screw hole, so that the prefabricated block can be conveniently filled into the screw hole, and the rear surface area of the prefabricated block is large, so that a worker can press the prefabricated block tightly by using a rubber hammer, the prefabricated block and the side wall of the groove body generate pretightening force, the prefabricated block and the side wall of the groove body are combined more closely and firmly, and the seepage-proofing capacity of the outer wall body is improved; meanwhile, compared with the traditional method for plugging the screw hole by using cement mortar, the precast block can be subjected to compactness inspection before being plugged, so that the plugging depth and compactness can be controlled;
