[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.

[0003] In order to improve the connection strength of the steel bars and prevent cracking at the wet joints, the existing wet joint anti-corrosion components of building concrete composite beams usually need to fix the plate-like body on the concrete beam by bolts to seal the wet joints of the concrete beams. However, the exposed bolts are severely corroded after long-term use, causing the bolts to loosen, making it easy for rainwater or other corrosive media from the outside to penetrate into the wet joints and cause cracking, thereby reducing the use effect of the anti-corrosion components. When protecting the bolts, sealed protection is generally used. However, after the bolts are installed, it is difficult to inspect and repair the bolts. Once water penetrates into the simple fully wrapped protection, the bolts will still be corroded. Therefore, a structure is needed to solve the problem. Utility Model Content

[0023] Embodiment 1

[0024] Reference Figure 1-4 , a concrete component joint anti-corrosion structure, comprising a first concrete beam component 1 and a second concrete beam component 2, an anti-corrosion mechanism 3 is detachably connected between the first concrete beam component 1 and the second concrete beam component 2, and a plurality of bolts 5 are connected between the anti-corrosion mechanism 3 and the first concrete beam component 1 and the second concrete beam component 2, a plurality of auxiliary mechanisms 4 are arranged inside the anti-corrosion mechanism 3, the first concrete beam component 1 and the second concrete beam component 2 are connected and fixed by the bolts 5 and the anti-corrosion mechanism 3, and the anti-corrosion mechanism 3 is weighted by the auxiliary mechanism 4 to improve the stability of the anti-corrosion mechanism 3;

[0025] The anti-corrosion mechanism 3 includes a protective shell 31, the inner wall of which is fixedly connected to a middle partition 32, and two columns 34 are also fixedly connected inside the protective shell 31. The two columns 34 are symmetrically arranged about the middle partition 32, and the top of the column 34 is fixedly connected to a shaft rod 36. A movable plate 33 is rotatably connected between the middle partition 32 and the shaft rod 36, and a connecting ear 35 is fixedly connected to the side of the movable plate 33 close to the shaft rod 36. The connecting ear 35 is coaxially rotatably connected to the shaft rod 36. The bolt 5 is arranged in the protective shell 31, and a limiting assembly is arranged between the middle partition 32 and the movable plate 33.

[0026] In the present embodiment, specifically, when installing the bolt 5, the movable plate 33 is rotated to disengage it from the middle partition plate 32 to form an open area. After the bolt 5 is installed, the movable plate 33 is rotated again to snap the movable plate 33 closed, thereby protecting the bolt 5 from contact with external rainwater and improving the service life of the structure. Screws can also be connected between the movable plate 33 and the middle partition plate 32 to prevent the movable plate 33 from being easily opened. The arrangement of the auxiliary mechanism 4, the protective shell 31 and the movable plate 33 can also effectively drain and guide water to prevent rainwater from stagnation and accumulation and corroding the mechanism, thereby extending the service life of the structure.

[0027] Embodiment 2

[0028] like Figure 4 As shown, this embodiment is basically the same as embodiment 1. Preferably, the limiting assembly includes a clamping block 37 and a limiting plate 38. The clamping block 37 is fixedly connected to the movable plate 33, the limiting plate 38 is fixedly connected to the middle partition plate 32, and a groove that is clamped with the clamping block 37 is provided on the limiting plate 38.

[0029] In this embodiment, specifically, when in use, the movable plate 33 is limited by the engagement of the block 37 and the groove on the limiting plate 38 to maintain a closed state, and the entire operation is relatively convenient, which facilitates the installation and maintenance of the bolt 5.

[0030] Embodiment 3

[0031] like Figure 4 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the auxiliary mechanism 4 is arranged between two adjacent bolts 5. The auxiliary mechanism 4 includes a stopper 41, a drying cotton 42 and a counterweight 43. There are multiple stoppers 41, and they are all arranged between two adjacent bolts 5. The drying cotton 42 is stuck between the two stoppers 41, and the counterweight 43 is pressed on the drying cotton 42.

[0032] In the present embodiment, specifically, during use, the auxiliary mechanism 4 can effectively solve the problem of a small amount of water penetrating into the protective shell 31. When a small amount of rainwater enters, it will generally slide down along the inner wall of the protective shell 31. When it accumulates to a certain amount, it will preferentially contact the dry cotton 42 close to the inner wall of the protective shell 31. The dry cotton 42 absorbs the rainwater. After a period of time, the maintenance personnel can replace and maintain it to prevent rainwater from penetrating and accumulating to soak and corrode the bolts 5, thereby extending the service life of the bolts 5.

[0033] Embodiment 4

[0034] like Figure 1-Figure 4As shown, this embodiment is basically the same as embodiment 1. Preferably, in order to facilitate the discharge of rainwater, a plurality of drainage holes 311 are provided on the outer wall of the protective shell 31, a drainage groove is integrated on the top of the movable plate 33, and an arc-shaped water guide plate 312 is provided on the side of the column 34 away from the middle partition 32. In order to facilitate the opening and closing of the movable plate 33, a groove 331 is provided on the top of the movable plate 33, and absorbent cotton 332 is fixedly connected to the bottom of the movable plate 33. The absorbent cotton 332 is in contact with the inner wall of the protective shell 31, and the height of the column 34 is less than the height of the block 37 on the middle partition 32.

[0035] In the present embodiment, specifically, when it rains, rainwater falls into the drainage groove of the movable plate 33. Due to the height difference between the column 34 and the block 37 on the middle partition plate 32, the movable plate 33 remains inclined, and the rainwater slides along the drainage groove to the arc-shaped water guide plate 312. The arc-shaped water guide plate 312 effectively prevents the accumulation of rainwater and drains the rainwater through the drainage hole 311. The provision of the absorbent cotton 332 further prevents the rainwater from sliding along the inner wall of the protective shell 31, thereby improving the anti-corrosion effect of the structure.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
