Embodiment Construction
[0014] figure 1 The composite hydraulic expansion joint watertight structure shown includes expansion joint, steel plate 1, U-shaped metal channel plate 2, and connector 3. The U-shaped metal channel plate 2 is made of copper or stainless steel. The expansion joint with large deformation should use copper Stainless steel sheet should be used for small deformation joints. The steel plate 1 has a connector 3 at one end of the expansion joint. The connector 3 is a protruding angle or tooth plate. The other end of the steel plate 1 is bent. Zinc layer, the steel plate 1 is symmetrically arranged on both sides of the expansion joint, the U-shaped metal groove plate 2 includes a U-shaped groove and a flat part connected to both ends of the U-shaped groove, and the two ends of the U-shaped metal groove plate 2 are respectively connected to the steel plate 1, To form a water-stop structure, the U-shaped groove part of the U-shaped metal groove plate 2 is installed in the middle of the...

The invention relates to a composite hydraulic expansion joint water stop structure. The water stop structure comprises an expansion joint and a U-shaped metal trough plate, wherein steel plates are symmetrically arranged on the two sides of the expansion joint; connectors are remained at certain ends, close to the expansion joint, of the steel plates, and the other ends of the steel plates are provided with bends; the steel plates are cast in concrete; the U-shaped metal trough plate comprises a U-shaped trough and flat plate parts connected with the two ends of the U-shaped trough; the U-shaped trough is partially arranged in the middle of the expansion joint; the two ends of the U-shaped metal trough plate are connected with the steel plates; the flat plate is partially cast in the concrete; the periphery of the U-shaped metal trough plate is filled with a polyurethane material layer. The structure has the advantages of suitability for factory production, easiness in guarantee of quality, larger rigidity of the steel plates of the parts buried in the concrete, low probability of damage during construction, good anti-seepage effect, good deformation adaptability, adjustability and the like.
Description
technical field [0001] The invention relates to a composite hydraulic expansion joint water-stop structure, which belongs to the technical field of construction. Background technique [0002] Expansion joint waterstop structures are commonly used in hydraulic structures, cavern buildings and underground projects. Usually, rubber waterstops, copper plate waterstops and galvanized iron plate waterstops are used for waterstops in projects. In actual engineering, because the traditional waterstop is not suitable for protection, the installation quality is not easy to control, the concrete vibration process is easily damaged, and other interferences in construction, the waterstop effect is reduced, resulting in high cost of anti-leakage treatment in the later stage of the project, and leaving There are hidden dangers. [0003] Chinese Utility Model Patent Specification CN 200949270 Y discloses such a steel plate water-stop sheet for expansion joints. It consists of a st...
