Description

Technical Field

[0001] The utility model belongs to the technical field of precast components, and particularly relates to a joint waterproof structure for precast components. Background Art

[0002] Concrete precast components are building components prefabricated in a factory with concrete as the basic material, including beams, plates, columns, and building decoration accessories, etc. After reasonable design and calculation of some components, they are first produced in the factory. During on-site installation construction, installers only need to assemble the pre-designed and produced concrete precast components according to the assembly requirements to complete the construction.

[0003] Since the building is assembled with concrete precast components during the construction process, there are splicing joints between two concrete precast components. Long-term erosion of the joints by external water easily leads to water leakage at the joints. Since the waterproof rubber strip used for waterproof arrangement is a flexible material, it is relatively difficult to accurately assemble such a flexible waterproof rubber strip into the splicing joint. When the waterproof rubber strip is bent, it will affect the waterproof performance. When the waterproof rubber strip is arranged outside the splicing joint of the precast component, the exposed waterproof rubber strip will have the disadvantages of poor aesthetics and reduced service life due to external influences.

[0004] Therefore, a joint waterproof structure for precast components is needed to solve the problems in the prior art that it is relatively difficult to accurately assemble a flexible waterproof rubber strip into the splicing joint and the external waterproof rubber strip affects its service life.

The joint waterproof structure includes an assembly chute, a guiding slider, and a waterproof strip. The assembly chute is formed on the opposite one-side surfaces of the first precast component and the second precast component. The guiding slider is arranged between the first precast component and the second precast component. The waterproof strip is arranged on the opposite one-side surfaces of the upper and lower two guiding sliders. A straightening mechanism is arranged outside the waterproof strip.
