Technical Field

[0001] This utility model relates to the technical field of highway, railway, and municipal engineering, specifically a device for rapid construction of spliced ​​wet joints. Background Technology

[0002] Currently, the main construction techniques used in the construction of spliced ​​wet joints include: first, building a construction platform at the bottom of the beam, with workers descending from the top of the beam to the platform via ladders to work; and second, using winches on the bridge deck to transport formwork, with workers operating both on and under the bridge. However, both methods have certain drawbacks: the installation, dismantling, and transportation of formwork are cumbersome, leading to low construction efficiency, increased costs, and significant safety risks for workers. This is especially true when space is limited under the bridge, further increasing the construction difficulty. Traditional wet joint construction methods for bridge decks appear inefficient, unsafe, and extremely difficult under these circumstances.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1 to 6This utility model provides a technical solution: a device for rapid construction of spliced ​​wet joints, including an upper template 1, a lower template 2, a sleeve 3, and a threaded steel bar 4. The threaded steel bar 4 passes through a through hole, and the position of the limiting ball 21 corresponds to the position of the through hole, with the limiting ball 21 abutting against the threaded steel bar 4. A rectangular groove is provided inside the sleeve 3, and the end of the rectangular slider 22 is located inside the rectangular groove, allowing the rectangular slider 22 to slide along the length of the rectangular groove. The end of the positioning slider 17 is located inside the positioning groove. A threaded hole is provided at the top of the sleeve 3, and a lead screw 5 is threadedly connected inside the threaded hole. A V-shaped plate 6 is installed at the end of the lead screw 5, and a round block 7 is installed on the outer surface of the lead screw 5. A pressure plate 8 is installed at the bottom of the round block 7, and the bottom of the pressure plate 8 abuts against the top of the upper template 1. Both the upper template 1 and the lower template 2 have round holes inside, and the sleeve 3 passes through the round holes. A cavity block 9 is installed on the inner wall of the pressure plate 8, and the cavity block 9 has openings in the front-back direction as the depth direction and the left-right direction. The T-shaped slide is oriented along the length direction. The end of the T-shaped slider 13 is located inside the T-shaped slide. The T-shaped slider 13 can slide along the length direction of the T-shaped slide. A limit spring 10 is installed inside the cavity block 9. A limit block 11 is installed at one end of the limit spring 10. A push block 12 is installed in front of the limit block 11. The T-shaped slider 13 is installed behind the limit block 11. An adjustment box 14 and a threaded column 15 are installed at the bottom of the lower template 2. A positioning groove with the vertical direction as the depth direction is opened on the top of the adjustment box 14. The end of the positioning block 19 is inserted into the positioning groove. A slot with the horizontal direction as the depth direction is opened on both sides of the positioning block 19. The end of the slot is inserted into the slot. A positioning slide is opened inside the adjustment box 14. A return spring 16 is installed inside the positioning slide. A positioning slider 17 is installed at one end of the return spring 16. A slot 18 is installed at the end of the positioning slider 17. A positioning block 19 is installed at the bottom of the sleeve 3.

[0027] During use and installation, first, allow the threaded steel bar 4 to pass through the through hole, place the sleeve 3 between the two T-beams, ensuring both ends of the threaded steel bar 4 abut against the T-beams. Pull the locking block 18, causing it to move the positioning slider 17, which in turn compresses the return spring 16, allowing the positioning slider 17 to slide along the length of the positioning groove, thus disengaging the locking block 18 from the groove. Then, move the lower template 2, bringing it into contact with the T-beams, allowing the sleeve 3 to pass through the round hole on the lower template 2, and inserting the end of the positioning block 19 into the positioning groove. Release the locking block 18, and the elastic tension of the return spring 16 will allow the end of the locking block 18 to insert into the groove, facilitating the positioning of the positioning block 19 and the installation of the sleeve 3 with the lower template 2. Move the upper template 1, allowing the sleeve 3 to pass through the upper template 2. The through hole on template 1 allows the upper template 1 to abut against the T-beam, pushing the push block 12, causing the locking block 18 to move the T-shaped slider 13, causing the limiting spring 10 to contract under force, and causing the limiting block 11 to contract and enter the cavity block 9. Tightening the V-shaped plate 6 causes the screw 5 to enter the threaded hole inside the sleeve 3, causing the round block 7 and pressure plate 8 to rotate with the screw 5, so that the pressure plate 8 abuts against the upper template 1. Tighten to the appropriate position, release the push block 12, and through the elastic tension of the limiting spring 10, the end of the limiting block 11 is inserted into the limiting groove, facilitating the connection between the upper template 1 and the sleeve 3, and facilitating quick connection. The connecting rope 24 facilitates the pulling of the lower template 2. Applying release agent to the upper template 1 and lower template 2 facilitates demolding of the upper and lower templates 2, improving practicality.

[0028] Example 2

[0029] Please see Figures 1 to 5 This utility model provides a technical solution: a device for rapid construction of spliced ​​wet joints, wherein a tension spring 20 is installed inside the sleeve 3, a limiting ball 21 is installed at one end of the tension spring 20, and rectangular sliders 22 are installed on both sides of the limiting ball 21. Limiting grooves and through holes are respectively opened on the outer surface of the sleeve 3. There are several limiting grooves, which are arranged in a circular array. The position of the limiting groove is higher than the position of the through hole. The end of the limiting block 11 away from the limiting spring 10 is inserted into the inside of the limiting groove. A nut 23 is provided on the outer surface of the threaded column 15, and a connecting rope 24 is provided on the outer surface of the nut 23.

[0030] When in use, when the threaded steel bar 4 enters the through hole, the end of the threaded steel bar 4 abuts against the limiting ball 21. The limiting ball 21 is subjected to a downward component of force, causing the limiting ball 21 to move downward. This causes the tension spring 20 to contract, causing the rectangular slider 22 to slide along the length of the rectangular groove. Through the elastic tension of the tension spring 20, the limiting ball 21 pushes the threaded steel bar 4, which helps to limit the position of the threaded steel bar 4, increases the friction, and improves the reinforcement effect of the threaded steel bar 4, thus improving its practicality.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
