[0002] According to the current bridge construction specifications and design drawings, after the erection of the prefabricated T-beam is completed, the steel bars between the beams must be connected in time, and then the concrete wet joints must be poured as required. According to conventional construction technology, wet joints are mostly reinforced with a formwork reinforcement system of hanging formwork and tension screws. This formwork reinforcement system has good reinforcement effect, convenient construction, and low cost. However, it is not easy to remove the bottom formwork after the wet joint is poured. It is very easy for workers to use violent removal due to the difficulty in removing the formwork. Such operations will affect the construction quality and progress of the wet joints, and will also cause excessive consumption of materials and human resources.
[0003] Therefore, it is urgent to facilitate workers to remove the bottom formwork in the formwork reinforcement system more effectively and completely to ensure the construction progress and quality. Utility Model Content

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0020] See also Figures 1 to 3The utility model provides a prefabricated T-beam wet joint 9 template removal device, which is used in concrete wet joint pouring occasions. It is mainly composed of a pulling device and a reinforcement device. The pulling device is composed of a pulling rod 1, a PVC protective sleeve, two mountain clamps, and two hexagonal nuts. The reinforcement device is composed of a hexagonal nut and four threaded steel back ribs 6. One end of the pulling rod 1 passes through the bottom template 7. Both ends of the pulling rod 1 are provided with mountain clamps 3, pulling device hexagonal nuts 4 and threaded steel back ribs 6. The pulling device hexagonal nuts 4 are arranged on one side of the mountain clamp 3 facing the two ends of the pulling rod 1, and the threaded steel back ribs 6 are arranged on the side facing the middle of the pulling rod 1. The middle sleeve of the pulling rod 1 is provided with a PVC protective sleeve 2, and the reinforcement device hexagonal nuts 5 are arranged between the PVC protective sleeve 2 and the bottom template 7. It also includes a prefabricated T-beam wet joint 9 arranged on the prefabricated T-beam flange plate 8, one end of the drawing rod 1 passes through the prefabricated T-beam wet joint 9, the threaded steel back rib 6 on the bottom mold side of the prefabricated T-beam wet joint 9 is arranged between the mountain-shaped card 3 and the bottom mold plate 7, and a square wood back rib 10 is arranged between the threaded steel back rib 6 on the bridge deck side and the prefabricated T-beam flange plate 8.
[0021] Preferably, the length of the wire rod 1 is 500 mm and the diameter is 12 mm. Setting the length to 500 mm has the advantage of being moderate in length, which can ensure that it passes through the formwork and the concrete wet joint and provides sufficient support. The wire rod with a diameter of 12 mm has good tensile strength and can withstand the tension during construction.
[0022] Preferably, the hexagonal nut 4 of the pulling device and the hexagonal nut 5 of the reinforcing device are matched with the pulling rod 1, and both are M12. The nuts of M12 specification are matched with the pulling rod 1 to ensure the tightness and reliability of the connection.
[0023] Preferably, the length of the PVC protective sleeve 2 is 250 mm and the diameter is 25 mm. The length of 250 mm can provide protection for the wire rod 1 without interfering with the reinforcement of the formwork, prevent the wire rod from directly contacting the wet joint concrete, and reduce corrosion and wear. The sleeve with a diameter of 25 mm is suitable for a 12 mm wire rod to pass through, which can protect the wire rod without excessively affecting the overall strength of the structure.
[0024] Preferably, the diameter of the threaded steel back rib 6 is 28 mm, and the length is adjusted accordingly. The length of the threaded steel back rib 6 is adjustable to adapt to wet joints and templates of different widths, providing flexibility. The threaded steel with a diameter of 28 mm has good bending resistance, can effectively support the template and prevent deformation.
[0025] Preferably, the thickness of the bottom formwork 7 is 15 mm, and the size is adjusted accordingly. Increasing the thickness of the formwork can improve its overall stability and load-bearing capacity, which is very important for bearing the weight of concrete wet joints and other loads that may be encountered during construction. Thicker formwork usually means higher turnover times, which is particularly beneficial for long-term projects or situations where the formwork needs to be reused many times. The bottom formwork 7 is relatively easy to demould and has good corrosion resistance, so that the formwork can remain in good condition even in harsh construction environments, reducing maintenance costs.
[0026] Preferably, the specification of the square wood back rib 10 is 50*100mm, and the length is adjusted accordingly.
[0027] First, weld the two threaded steel bars to the mountain-shaped clamp 3 on the bottom mold side as a whole, then insert the tensioning rod 1 into the PVC protective sleeve 2, and screw the end of the screw rod on the bottom mold side into the M12 reinforcement device hexagonal nut 5, 15mm bottom mold plate 7, the mountain-shaped clamp 3 with threaded steel back rib 6, and the M12 tensioning device hexagonal nut 4 in sequence; screw the end of the screw rod on the bridge deck side into the mountain-shaped clamp 3 with threaded steel back rib 6 and the M12 tensioning device hexagonal nut 4 in sequence.
[0028] See also Figures 1 to 3 This dismantling device has both reinforcement and dismantling functions. After the wet joint formwork is reinforced and poured to reach the dismantling strength, the wet joint bottom formwork can be pushed out by the hexagonal nut fastened in advance at the bottom of the screw. After the bottom formwork is cleaned and coated with a release agent, it can be used for the next section of wet joint construction. This effectively solves the problem of workers resorting to violent dismantling and damaging the formwork when it is difficult to dismantle the wet joint bottom formwork.
