Description
Technical Field
The utility model relates to a waterproof node specifically is outer accuse node is prevented in prefabricated assembled outer wall length and breadth concatenation seam.
Background
The prefabricated assembly type is a building which is mainly composed of concrete prefabricated parts and formed by assembly and connection; after main concrete components (a prefabricated non-stressed outer wall, a prefabricated convex window, a prefabricated outer wall, a prefabricated inner wall, a prefabricated heat-insulation outer wall plate, a prefabricated composite slab, a prefabricated staircase, a prefabricated balcony composite slab, a prefabricated composite beam, a prefabricated equipment platform plate and the like) prefabricated in a factory are transported to the site, the stress of the steel bars can be effectively transmitted through the connection of the vertical steel bars and the grouting sleeve, so that the upper steel bars and the lower steel bars can work together at the abutted seams to form an integral assembly type structure together with poured concrete, and the prefabricated assembly type building has the advantages of high overall precision, short construction period, low energy consumption and the like. Because the components are assembled in blocks, a large number of assembly joints can be left between the components, the inner side construction has no good technology, the joint can easily become a water leakage channel, the process flows of the assembly joints are more, the work efficiency and the quality are greatly reduced, and the difficulty for the anti-leakage treatment of the outer wall of the building is increased.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a prefabricated external wall longitudinal and transverse splicing seam internal-defense external-control node, which comprises a vertical steel plate, wherein the vertical steel plate is arranged in a tongue-and-groove at the inner side of the prefabricated external wall; a bolt sleeve is arranged in the rabbet, and the vertical steel plate is fixed in the rabbet through a bolt; the outer side of the prefabricated outer wall is respectively provided with a U-shaped groove with a transverse joint and a vertical joint, a U-shaped plate is arranged in the U-shaped groove, a galvanized iron sheet is arranged at the end part of the U-shaped plate, a galvanized connection screw fixes the U-shaped plate on the U-shaped groove through the galvanized iron sheet, and the U-shaped plate is spliced into a whole at the longitudinal joint and the transverse joint in a U-shaped plate rabbet mode.
Furthermore, a small drainage groove is arranged at the bottom of one side of the U-shaped groove. The inner side of the U-shaped groove of the transverse abutted seam is provided with a small drainage groove.
Furthermore, the U-shaped plate is made of PVC.
The utility model discloses simple structure, convenient operation, replicability is high, is applicable to the construction of preparation personnel.
