The utility model patent with the application number 202221869867.7 discloses a water-stopping screw, which is provided with an annular neck at the joint of a water-stopping steel plate and the screw, cone nuts are screwed on the screw at the positions on two sides of the water-stopping steel plate, annular grooves are arranged on the cone nuts at the positions on the periphery of the screw, and nuts are screwed on the outer sides of the two cone nuts; in the structure of nut, the inboard laminating of tubular root has the gasket, and the gasket cup joints on the screw rod, and the outside of tubular root and well body interconnect, have the abduction arm at the side of tubular root and well body junction, have the clearance between abduction arm and the gasket, have hem portion at the end of abduction arm, have the notch portion between hem portion and well body, be convenient for adjust and stability are better, but this stagnant water screw rod is in follow-up demolishment in-process, and cone nut is inconvenient to take out, wastes time and energy.
Disclosure of utility model
The utility model aims to provide the detachable water stop screw which is spliced in a detachable mode, is convenient to install and detach, has good structural stability, can adapt to construction of walls with different thicknesses, has high construction efficiency, saves construction cost and has strong practicability.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
The detachable water stop screw comprises a middle screw and external screws detachably arranged at two ends of the middle screw, wherein water stop plates are fixedly arranged on the middle screw, threaded connecting rods are arranged at two ends of the middle screw, the external screws are sleeved on the threaded connecting rods, and the external screws are connected with the middle screw by nuts; a conical plugging piece is detachably arranged on the external screw rod, and two ends of the conical plugging piece respectively prop against the end parts of the template and the middle screw rod; a seal is provided between the intermediate screw and the outer screw or conical plug.
Preferably, the conical plug is made of wood or rubber material.
Preferably, an annular mounting groove is formed in the end portion of the outer screw, and a sealing rubber ring is mounted in the annular mounting groove and is used for sealing and connecting the end portions of the outer screw and the middle screw.
Preferably, a butterfly nut is mounted on the external screw through threads, and the butterfly nut fastens the template and the conical plugging piece.
Preferably, the water stop plate is fixedly arranged at the middle position of the middle screw rod through welding.
In the utility model, the external screw and the middle screw are combined in a detachable connection mode, so that the disassembly operation after construction is facilitated, and the tapered plugging piece adopts a tapered structure, so that the disassembly after concrete solidification is facilitated. The sealing piece arranged between the middle screw and the external screw can seal the middle screw and the external screw, so that the concrete is prevented from solidifying at the connecting position of the middle screw and the external screw, and the disassembly operation is convenient. The conical plugging piece is made of wood or rubber materials, and the materials are convenient to separate from concrete and convenient to detach. After the threaded connecting rod is cut, the residual part improves the stability of filling connection when the conical plugging piece is filled in the subsequent process.
