Description

Technical Field

[0001] The present application relates to the field of bridge engineering construction technology, and in particular to a prefabricated box girder railing groove positioning tool. Background Art

[0002] Precast box girders are widely used in modern bridge construction due to their efficient construction methods and excellent structural performance. However, after the erection of the precast box girders, subsequent construction on the bridge deck, especially the construction of the cable trough walls, often faces significant difficulties and risks. This phase of construction involves the precise positioning of the railing slots and the installation of embedded bolts. Improper handling will directly affect the quality of the subsequent railing installation, and in turn, negatively impact the overall safety and service life of the bridge.

[0003] In actual construction, the positioning of vertical wall railing channels is often constrained by a variety of factors, including the complexity of the construction environment, the precision of workers, and the limitations of existing tools. These factors make accurate railing channel installation extremely difficult, resulting in inaccurate bolt placement, ultimately affecting the installation effect and project quality of the railing.

[0004] In order to meet the above challenges, it is urgent to develop a tool for positioning the railing grooves in the vertical walls of prefabricated box girders. The tool must solve the problems of difficult positioning of the railing grooves and inaccurate pre-embedded railing bolts, ensure the accurate installation of the railing grooves on the vertical walls, and enable the embedded bolts to be directly cast in the vertical walls of the prefabricated box girders. Utility Model Content

[0005] In order to solve the problems of difficulty in positioning railing grooves and inaccurate pre-embedded railing bolts, the present application provides a prefabricated box girder railing groove positioning tool.

[0007] A prefabricated box girder railing groove positioning tool, comprising a railing groove mold, embedded bolts and a mounting frame, wherein the mounting frame is connected to the railing groove mold and is used to install the railing groove mold on a vertical wall formwork, and the embedded bolts are provided at the bottom of the railing groove mold and are detachably connected to the railing groove mold;

[0008] During operation, concrete is poured in the vertical wall formwork. After the concrete is initially set, the embedded bolts and the railing groove mold are removed. The embedded bolts are buried in the concrete. The groove formed by the railing groove mold is the railing groove. The positioning tool is removed.

[0009] By adopting the above technical solution, the installation frame is connected to the railing groove mold and fixed to the vertical wall formwork, the embedded bolts are detachably connected to the railing groove mold, and the position of the railing groove mold is adjusted according to the design requirements; after the installation of the tooling is completed, concrete is poured, and the concrete is poured into the vertical wall formwork to cover the embedded bolts. After the concrete is initially set, the embedded bolts and the railing groove mold are removed. At this time, the embedded bolts are firmly buried in the concrete, and the groove formed by the railing groove mold is the railing groove. The positioning tooling is removed to check whether the formed railing groove meets the design requirements, and the embedded bolts are fixed. The installation status can be confirmed; the tooling design allows for quick installation and disassembly, saving workers' time for adjustment and positioning, and improving construction efficiency. The dedicated railing groove mold and installation frame ensure the accurate positioning of the railing groove, thereby improving the accuracy of construction. The detachable design of the embedded bolts and railing groove mold allows the embedded bolts to be directly cast in the vertical wall of the prefabricated box beam, and can reduce safety hazards and construction risks caused by improper positioning during construction; the tooling can be reused, reducing material waste and the possibility of rework, thereby effectively saving construction costs.

[0010] In a specific possible implementation scheme, the railing groove mold is provided with a through hole, the embedded bolt passes through the through hole into the railing groove mold, and is fixed in the railing groove mold by a nut.

[0011] By adopting the above technical solution, the embedded bolts are inserted into the railing groove mold through the through holes and fixed with nuts to form a stable connection. This structure improves the stability of the mold during the concrete pouring process and prevents the mold from displacement or deformation. The through-hole design makes the installation of the embedded bolts easier and does not require additional docking or complicated fixing methods, reducing the operation difficulty and time for construction workers. The nut fixing method makes the disassembly process quick and simple. The mold can be quickly removed after construction, reducing working hours and improving construction efficiency.

[0012] In a specific possible implementation scheme, the mounting frame includes a frame and a fixed end head, the frame body is inserted into the railing groove mold and connected to the railing groove mold, the frame body extends outward from the railing groove mold and has the fixed end head extended therefrom, and the fixed end head is mounted on the vertical wall formwork to install the railing groove mold on the vertical wall formwork.

[0013] By adopting the above technical solution, during operation, the frame is inserted into the railing groove mold and connected to it to form a stable overall structure, ensuring that the mold will not be displaced or deformed during the construction process. The fixed end is directly mounted on the vertical wall formwork, which simplifies the installation process of the railing groove mold, makes positioning more accurate, and reduces the skill requirements for construction personnel.

[0014] In a specific possible implementation scheme, the frame abuts against one side of the outer formwork of the vertical wall formwork.

[0017] By adopting the above technical solution, the fixed end is composed of an outer mold end and an inner mold end, providing double support, enhancing the stability of the overall structure, and ensuring that it can withstand greater pressure during the pouring process. This design provides stable support and flexible adjustment capabilities, which not only improves the pouring quality and safety, but also simplifies the construction process, making the overall construction more efficient and reliable.

[0018] In a specific possible implementation scheme, the outer mold end and the inner mold end are fixed to the vertical wall formwork by spot welding.

[0019] By adopting the above technical solution, the outer mold end and the inner mold end are fixed to the vertical wall formwork by spot welding, which provides a firm connection and significantly enhances the overall stability of the structure. The spot welding method makes the installation process simpler and faster, without the need for complex mechanical fixing methods, saving construction time and labor costs.

[0020] In a specific possible implementation scheme, a fixing plate is provided on the outer mold end and the inner mold end, and the fixing plate is fixed to the vertical wall formwork by fixing nails.

[0021] By adopting the above technical solution and using the design of fixing plates and fixing nails, installation and disassembly are more convenient, and the position can be quickly adjusted to adapt to different construction needs, thereby improving construction flexibility. The fixing method of fixing nails can be easily disassembled and replaced when the tooling needs to be disassembled, reducing time costs. In addition, the design of the fixing plate can effectively disperse the load applied to the mold, which not only enhances the stability and safety of the structure, but also improves construction flexibility and efficiency, making the overall construction process more efficient and reliable.

[0022] In a specific possible implementation scheme, it also includes a positioning reinforcement plate, one side of which is connected to the outer wall of the railing groove mold, and the other side is mounted on the inner mold of the vertical wall formwork. The positioning reinforcement plate is used to locate the position of the railing groove and the embedded bolts.

[0023] By adopting the above technical solution, the design of the positioning reinforcement plate ensures the accurate positioning of the railing groove mold and the embedded bolts, which helps to maintain the consistency of each part during the pouring process and ensure the construction quality; one side of the positioning reinforcement plate is connected to the outer wall of the railing groove mold, and the other side is supported on the inner mold to form a stable support system, effectively preventing the mold from displacement or deformation during construction.

In this embodiment, a portion of the mounting frame 3 is inserted into the railing groove mold 1 and welded to the railing groove mold 1. The mounting frame 3 is used to mount the railing groove mold 1 on the vertical wall formwork 4. A portion of the mounting frame 3 extends out of the railing groove mold 1 and is mounted on the vertical wall formwork 4. The embedded bolts 2 are provided at the bottom of the railing groove mold 1 and are detachably connected to the railing groove mold 1.

[0038] During operation, the installation frame 3 is connected to the railing groove mold 1, and it is erected and fixed on the vertical wall formwork 4, and the embedded bolts 2 are detachably connected to the railing groove to complete the assembly of the positioning tooling. At this time, the position of the railing groove mold 1 is adjusted according to the design requirements to ensure that the position of the railing groove mold 1 meets the design; after the installation of the tooling is completed, concrete 10 is poured and poured into the vertical wall formwork 4 to cover the embedded bolts 2. After the concrete 10 is initially solidified, the embedded bolts 2 and the railing groove mold 1 are removed. At this time, the embedded bolts 2 are firmly buried in the concrete 10, and the groove formed by the railing groove mold 1 is the railing groove. The positioning tooling is removed, and the formed railing groove is checked to see if it meets the design requirements, and the installation of the embedded bolts 2 is confirmed.

[0039] During this process, the design of the positioning tooling allows for quick installation and disassembly, saving workers time in adjustment and positioning, and improving construction efficiency. The dedicated railing groove mold 1 and the installation frame 3 ensure accurate positioning of the railing groove, thereby improving construction accuracy.

The abutment design allows the pressure applied to the mold during construction to be evenly distributed to the vertical wall formwork 4, reducing single-point stress and thereby reducing the risk of structural damage.

[0047] The outer mold end 33 and the inner mold end 34 are fixed to the vertical wall formwork 4 by spot welding, providing a firm connection and enhancing the overall stability of the structure. The spot welding method makes the installation process simpler and faster, without the need for complex mechanical fixing methods, saving construction time and labor costs. The spot welding design facilitates rapid disassembly after construction is completed, reducing disassembly time and improving construction efficiency.

[0048] The positioning tooling also includes a positioning reinforcement plate 7. In this embodiment, the positioning reinforcement plate 7 can be, but is not limited to, a steel pad.
