Embodiment Construction
[0014] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0015] Such as figure 1 As shown, a combined water-stop screw includes an inner rod 1, two detachable outer rods 2 arranged at both ends of the inner rod 1, the inner ends of the inner rod 1 and the two outer rods 2 are connected by a connecting piece, and the inner rod 1 is provided with a water-stop sheet 4 in the middle, and a retaining ring 5 is provided on the outside of the connection between the outer rod 2 and the connector.
[0016] In order to enhance the structural strength and facilitate disassembly and assembly, the retaining ring 5 is integrated with the outer rod 2, the connecting piece is an internally threaded connecting nut 3, and the inner end of the outer rod 2 and the two ends of the inner rod 1 are internally threaded with the connecting nut 3 Matching external thread. The integrated structure of the retaining...

The invention relates to a screw rod, in particular to a combined-type water stop screw rod. An integral water stop screw rod is tedious in manufacturing process, material reusability is poor, and labor and materials can be consumed. The combined-type water stop screw rod comprises an inner rod and two detachable outer rods arranged at the two ends of the inner rod. The inner rod and the inner ends of the two outer rods are connected through corresponding connecting pieces. A water stop strip is arranged in the middle of the inner rod. Baffle rings are arranged at the outer sides of the positions, connected with the connecting pieces, of the outer rods. According to the technical scheme, compared with the integral water stop screw rod, the outer rods of the combined-type water stop screw rod can be removed, reuse can be realized, and the materials are saved; and the connecting pieces and the inner rod with the water stop strip are kept in a concrete structure, and thus the wall waterproof effect is enhanced.
Description
technical field [0001] The invention relates to a screw, in particular to a combined water-stop screw. Background technique [0002] Substation projects generally contain underground structures such as emergency oil pools and rainwater pump wells. When setting up the formwork, a large number of water-stop screws are usually used for reinforcement, and integral water-stop screws are generally used. The manufacturing process of the integral water stop screw is cumbersome, the reusability of the material is poor, and labor and consumables are consumed. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, and to provide a combined water-stop screw for the purpose of increasing the reuse rate of materials and reducing costs. For this reason, the present invention takes the following technical solutions. [0004] A combined water-stop screw, co...
