[0002] Wet joints refer to the joints where the prestressed concrete beams are prefabricated in blocks, cantilevered and assembled into long-span continuous beams, and the beams are connected into a whole using cast-in-place concrete. The steel bars in the wet joints are important components for transmitting the interface shear force so that the two are stressed as a whole. Existing anti-corrosion components for wet joints of building concrete composite beams are designed to improve the connection strength of steel bars and prevent cracking at wet joint connections. For example, the patent application number is CN202320780256.3, and the name is a anti-corrosion component for wet joints of building concrete composite beams, which includes a left concrete beam and a right concrete beam. A sealing mechanism is arranged on the outer side of the fixing bolt, and the sealing mechanism includes a fixing plate. A sealing cover is connected to the outer side of the clamping block away from the clamping groove, and cover plates are movably connected to the two ends of the sealing cover. A clamping component is arranged on both sides of the sealing cover, and the clamping component includes a limiting cylinder, and the limiting cylinder has two limiting blocks that are engaged and slidable inside. Although the sealing mechanism is arranged to fully protect the fixing bolts and enhance the sealing effect of the wet joints, the sealing mechanism needs to be installed on the end faces of the bolted connections, which increases the corresponding costs.

The connection between the wet joint 3 and the groove 7 and the provision of the reinforcing connector 6 help to enhance the strength of the wet joint 3, while improving the firmness of the connection between the left concrete beam 1, the right concrete beam 2 and the concrete of the wet joint 3, thereby ensuring the service life of the concrete beam. A protective shielding member 4 is provided on the periphery of the wet joint 3. The protective shielding member 4 is used for the construction of the pouring cavity of the wet joint 3 in the early stage and is also an anti-corrosion component for protecting the wet joint 3 in the later stage. A pouring port 5 is provided at the upper end of the protective shielding member 4 to facilitate the pouring of concrete through the pouring port 5 to shape the concrete, while improving the sealing of the wet joint 3. The protective shielding member 4 reduces the bolt connection, thereby preventing the exposed bolts from being severely eroded after long-term use, causing the bolts to loosen, resulting in external rainwater or other corrosive media easily penetrating into the wet joint 3 and cracking, reducing the use effect of the anti-corrosion component.

[0023] Refer to Figure 4 As shown, the lower end surface of the groove 7 is provided with a rectangular through hole 9, and the upper end surface is provided with a plurality of through holes 48, and the through holes 48 are all distributed close to the adjacent beam reinforcement 8. The enclosure shielding member 4 includes a bottom plate 41 arranged at the bottom of the wet joint 3, a top plate 42 arranged at the top, and a front panel 43 and a rear panel 44 connecting the top plate 42 and the bottom plate 41. The bottom plate 41 is provided with a protrusion 45 corresponding to the rectangular through hole 9, and the protrusion 45 is provided with a threaded hole 46 corresponding to the through hole 48. The threaded hole 46 is connected with a vertical reinforcement 47. The upper end of the vertical reinforcement 47 passes through the through hole 48 and is connected to the top plate 42. The vertical reinforcement 47 and the beam reinforcement 8 are in a cross-vertical relationship through steel wire bundling. The connection of the top plate 42 and the bottom plate 41 through the vertical reinforcement 47 strengthens the fit between the top plate 42, the bottom plate 41 and the left concrete beam 1 and the right concrete beam 2, which helps to completely seal the wet joint 3 and enhance the tightness of the connection between the structures, thereby improving the overall strength of the bridge.

[0024] Refer to Figure 4As shown, a seal 10 is provided on the top plate 42 corresponding to the vertical steel bar 47, the cross section of the top plate 42 is an isosceles trapezoid, right-angle grooves 423 are provided on the left and right sides of the top plate 42, and a concave hole 424 is provided on the right-angle groove 423 corresponding to the vertical steel bar 47, and a first through hole 425 is provided at the bottom of the concave hole 424 for the vertical steel bar 47 to pass through, and a sealing ring 426 is provided on the first through hole 425. The concave hole 424 is filled with a sealing layer 427 and poured concrete, and the seal 10 is arranged on the right-angle groove 423. The seal 10 includes a sealing block 101 and an inclined baffle 102. The sealing block 101 is placed on the right-angle groove 423 and fits with the right-angle groove 423. The inclined baffle 102 is fixed with the right-angle groove 423 by screws to form a triangular through groove to clamp the sealing block 101 in the triangular through groove, thereby further strengthening the sealing of the connection, thereby preventing external rainwater or other corrosive media from penetrating from the connection.

[0025] Refer to Figure 2 As shown, the front and rear sides of the bottom plate 41 are both provided with guide blocks 411 and card slots 412, the front and rear sides of the top plate 42 are extended with baffles 421 corresponding to the guide blocks 411, and the baffles 421 are provided with guide slots 422, the front panel 43 and the rear panel 44 are provided with vertical guide slots 12 moving from bottom to top along the guide blocks 411 to achieve splicing, and the lower end surface of the vertical guide slot 12 is provided with a sliding card block 13. When the upper ends of the front and rear panels 44 are engaged with the guide slots 422, the sliding card block 13 is pushed to engage with the card slots 412, and the guide blocks 411 and the guide slots are connected. Due to the setting of 422, the front and rear panels 44 cannot be disassembled horizontally but can only be disassembled vertically. The sliding block 13 is then cooperated with the card slot 412 to ensure the tight connection between the front and rear panels 44 and the bottom plate 41.

When the concrete is poured to the height of the steel plate, the top plate 42 is installed. The first through hole 425 on the top plate 42 is aligned with the vertical steel bar 47 to abut against the upper end of the wet joint 3, a sealing ring 426 is placed at the first through hole 425, and the sealing layer 427 and the concrete layer are filled in the recessed hole 424. Then, pouring is continued through the pouring port 5 on the top plate 42, or the top plate 42 is installed first and then poured uniformly through the pouring port 5, thereby completing the construction of concrete for the wet joint 3, and then the recessed hole 424 is sealed and blocked by the sealing member 10, and finally, a water-based resin curing agent is applied on the outer surface of the pouring port 5 to form a coating layer to complete the sealing of the pouring port 5.
