Description

Technical Field

[0001] The utility model belongs to the technical field of water stop belts, and particularly relates to a water stop device for concrete construction joints. Background Technique

[0002] A construction joint is not a real "joint". It is just a bonding surface between the previously poured concrete that has exceeded the initial setting time and the subsequently poured concrete. This bonding surface is called a construction joint. If the pouring treatment measures at the joint of the construction joint are improper, leakage problems will occur; after retrieval, in the Chinese patent application with the application number CN202020537860.X, a water stop device for concrete construction joints is recorded. In this patent, by setting a water stop belt that can be clamped on the steel bars, the position deviation of the water stop belt during the pouring process is avoided.

[0003] However, there are still certain deficiencies in the above patent during actual use. In the cited patent, although the width of the card slot clamped to the steel bar can be adjusted, the distance between different card slots is fixed. When encountering steel bars with different densities, it is easy to have a situation where the position of the card slot does not correspond to that of the steel bar and cannot be clamped, resulting in poor flexibility. Therefore, it is necessary to design a new water stop belt to solve this problem. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a water stop device for concrete construction joints to solve the problem that the distance between different card slots at the bottom of the water stop belt is fixed in the above background technique, which easily causes a conflict with the position of the steel bar and cannot be clamped.

A bottom strip is connected to the bottom of the water stop belt body. A strip A and a strip B are movably connected to the bottom of the bottom strip. The strip A and the strip B are arranged oppositely, and the tops of both extend slidably into the interior of the bottom strip. An adjusting assembly is arranged between the tops of the strip A and the strip B and the bottom strip. The adjusting assembly includes a side strip-shaped groove, a threaded connecting piece, and a threaded hole. The side strip-shaped grooves are symmetrically opened on both sides of the bottom strip and lead to the interior of the bottom strip. The threaded holes are opened on one side of the tops of the strip A and the strip B. The threaded connecting piece is threadedly connected to the threaded hole, and the outer end of the threaded connecting piece extends out of the side strip-shaped groove.

[0006] Preferably, the threaded connecting pieces connected to the tops of the strip A and the strip B face in opposite directions and extend out of the opposite side strip-shaped grooves respectively.

[0007] Preferably, the adjusting assembly further includes an anti-detachment groove. The anti-detachment groove is opened on the inner wall of the threaded hole, and the inner end of the threaded connecting piece is in a T-shaped structure.

[0008] Preferably, a rubber pad is bonded to the opposite side surfaces of the strip A and the strip B, and anti-slip lines are provided on the rubber pad.

[0009] Preferably, a guiding assembly is arranged inside the bottom strip. The guiding assembly includes a guiding rod which is fixed inside the bottom strip and penetrates through the tops of the strip A and the strip B.

[0010] Preferably, the guiding assembly further includes guiding holes formed at the tops of the strip A and the strip B. The guiding rod is of a round rod structure, and the shape of the guiding hole matches that of the guiding rod.
