[0001] This application relates to the field of bridge deck construction, and in particular to a reinforcement device for the construction template of a protective wall on a high-speed railway bridge deck. Background Technology

[0002] The retaining wall on the bridge deck of a high-speed railway is an important component of high-speed railway construction. Its main function is to protect railway safety and prevent external objects and natural disasters from affecting high-speed trains. The retaining wall is usually constructed of concrete and built using formwork. The quality of the formwork directly affects the strength and stability of the retaining wall, so it is necessary to reinforce the construction formwork.

[0003] However, during the implementation of the relevant technical solutions, at least the following technical problems were found: The construction of the bridge deck protective wall generally adopts double-sided formwork erection and concrete pouring. The top openings of the inner and outer formworks are fixed with tie rods, and the outer support of the bottom opening is fixed at the upper limit of the B wall reinforcement. The inner support of the bottom opening needs to be fixed by planting reinforcement on the beam surface. When fixing the inner formwork, it is necessary to drill holes on the beam surface to plant reinforcement, which will damage the beam surface and result in low construction efficiency. Utility Model Content

[0016] This application discloses a reinforcement device for the construction template of a high-speed railway bridge deck protective wall. The steel pipe 60 inside the drainage hole 50, together with the I-beam 71 and the wooden wedge 72, squeezes the fixing plate 41 to limit the bottom of the fixing plate 41. Together with the steel bar limiting component on the outer bridge deck 20, the construction template 40 is fixed and stable. It is not necessary to drill holes and install steel bars on the bridge beam 10 to fix the construction template 40. It is also convenient to disassemble and reuse it for the next protective wall 30.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] Please refer to Figure 1 This embodiment provides a reinforcement device for the construction template of a protective wall on a high-speed railway bridge deck, including a compression limiting component 70 on the top of the bridge beam surface 10, an outer bridge deck 20 on one side of the bridge beam surface 10, a protective wall 30 on the side of the top of the bridge beam surface 10, and a construction template 40 on the outer side of the protective wall 30. The compression limiting component 70 is located on the side of the construction template 40 away from the outer bridge deck 20. The construction template 40 includes a building template, fixing plates 41, tie rods 42, connecting plates 43, and nuts 44. The building template is located on the outer side of the protective wall 30, and multiple pairs of fixing plates 41 are respectively located on both sides of the building template and on the protective wall 30. Tie rods 42 are arranged parallel to each other at equal intervals on both sides and are set on the top of a pair of fixed plates 41. Two connecting plates 43 are respectively sleeved on both ends of the tie rods 42. Nuts 44 are set on the side of the connecting plates 43 away from the protective wall 30. Nuts 44 are threaded to the tie rods 42. The protective wall 30 is cast and shaped by the building template. Multiple pairs of fixed plates 41 are tightly attached to both sides of the building template. The two fixed plates 41 are connected together by the tie rods 42 on the top of the two fixed plates 41. The rotation of the nuts 44 makes the connecting plates 43 tightly attached to the fixed plates 41, so that the two fixed plates 41 are fixed by the tie rods 42. Multiple tie rods 42 are fixed together with the building template to cast the protective wall 30.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3 Multiple drainage holes 50 are provided on the top of the bridge beam surface 10. A steel pipe 60 is installed inside the drainage hole 50. An extrusion limiting component 70 is installed between the steel pipe 60 and the construction template 40. The extrusion limiting component 70 is used to limit the construction template 40 on one side. A steel bar limiting component is installed on the outer bridge deck 20 to limit the other side of the construction template 40. The extrusion limiting component 70, which is installed between the steel pipe 60 and the other side of the construction template 40, limits one side of the construction template 40. The steel bars of the steel bar limiting component are installed on the B wall at the bottom of the cable trough cover plate. The steel bar limiting component supports the construction template 40 on the other side, making the construction template 40 more firmly fixed on the outside of the protective wall 30.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3The compression limiting component 70 includes an I-beam 71 and wooden wedges 72. The I-beam 71 is positioned on the top of the bridge beam surface 10, with one side of the I-beam 71 in contact with the steel pipe 60. Multiple wooden wedges 72 are respectively positioned at the bottom of multiple fixing plates 41 near one side of the I-beam 71, and are positioned between the I-beam 71 and the fixing plates 41. By positioning the I-beam 71 close to the side of the steel pipe 60 near the fixing plates 41, and in conjunction with the wooden wedges 72 whose width can be arbitrarily selected, the steel pipe 60 can be compressed under force when the wooden wedges 72 are installed. The formwork 40 is pressed against the side of the drain hole 50 away from the fixing plate 41. The fixing plate 41 can also be fixed by the force of the pressure. The reinforcement limiting component supports the fixing plate 41 on the other side, so that the construction formwork 40 can be stably fixed on the outside of the protective wall 30. This ensures the stability of the protective wall 30 during the pouring. It also eliminates the need to drill holes and plant reinforcement on the bridge beam surface 10, which would damage the bridge beam surface 10. When it needs to be dismantled, the wooden wedge 72 can be removed and the steel pipe 60 and I-beam 71 can be recycled to the next hole of the protective wall 30 for reuse. Dismantling and reuse are more convenient.

[0021] The functional principle of this application can be explained through the following methods:

[0022] In use, the formwork is placed on the side of the bridge beam 10, and the rebar limiting assembly is installed on the B wall of the outer bridge deck 20 to support the multiple fixing plates 41 and the formwork on the side closest to the outer bridge deck 20. The steel pipe 60 is placed into the drainage hole 50, and the I-beam 71 is installed between the steel pipe 60 and the multiple fixing plates 41 on the other side, with the I-beam 71 tightly attached to the steel pipe 60, so that the steel pipe 60 is on the side closest to the inner wall of the drainage hole 50 away from the protective wall 30. Then, the positions of the multiple fixing plates 41 are selected according to their positions. Select a wooden wedge 72 of appropriate width and install it between the I-beam 71 and multiple fixing plates 41, so that the I-beam 71 and the wooden wedge 72 can appropriately squeeze the bottom of the fixing plate 41, and fix the multiple fixing plates 41 on the other side. With the help of the steel bar limiting component, the building formwork and multiple fixing plates 41 are firmly fixed. When dismantling, take out the wooden wedge 72 on one side of the multiple fixing plates 41, and then remove the I-beam 71 and the steel pipe 60 in the drainage hole 50. It can then be recycled to the next hole of the protective wall 30 for reuse, making dismantling and reuse more convenient.
