Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to an embedded rubber water stop device. Background Art

[0002] Rubber waterstops are generally used in: deformation joints, expansion joints; construction joints; joints with special aging resistance requirements. When the concrete construction joints are deformed due to thermal expansion and contraction or load, the rubber waterstops rely on their own elasticity to effectively tighten and seal, prevent water leakage and seepage in the building structure, and play a shock-absorbing and buffering role. During the installation of the waterstop, the rubber waterstop should be partially or completely buried in the concrete. If there are many sharp stones and sharp steel bar heads in the concrete, the tear strength of plastic and rubber is 3-5 times lower than the tensile strength. When the waterstop is punctured or torn, the crack will expand without much external force. Therefore, during the positioning of the waterstop and the pouring of concrete, attention should be paid to the positioning method and the pouring pressure to avoid puncture of the waterstop, so during the positioning of the rubber waterstop and the pouring of concrete, attention should be paid to the positioning method and the pouring pressure to avoid puncture and affect the waterstop effect.

[0003] When pouring concrete after installing the traditional waterstop, the upper and lower templates are sometimes easily offset due to the impact and pressure of the concrete, which leads to the kinking and offset of the waterstop. When the above situation occurs during the pouring process, it is difficult to adjust the waterstop, thus affecting the waterstop effect. This tooling can greatly reduce the occurrence of waterstop distortion and offset.

[0004] To this end, we propose a mid-embedded rubber waterstop device. Utility Model Content
