Description

Technical Field

[0001] This utility model relates to a jig for processing precast square culvert steel cages, belonging to the field of precast square culvert steel cage processing technology. Background Technology

[0002] In recent years, with the vigorous promotion of high-standard farmland construction nationwide, the demand for culverts, as supporting hydraulic structures, has been increasing. However, traditional cast-in-place culverts suffer from drawbacks such as long construction cycles and difficulty in guaranteeing product quality, which restricts the progress of engineering construction. Precast culverts, on the other hand, benefit from the stable production environment in factories, with standardized preparation processes, digital monitoring and adjustment, precision templates, and stable curing conditions, resulting in better product quality. Among these processes, the fabrication of the reinforcing cage is a crucial step in the production of precast culverts. Currently, the fabrication of the reinforcing cage largely relies on manual adjustment of the main reinforcing bars for positioning, followed by binding or welding into a reinforcing frame. The remaining reinforcing bars are then fixed within the pre-formed main reinforcing frame to form a complete reinforcing cage. This process is time-consuming, makes it difficult to accurately control the spacing of the reinforcing bars, and easily leads to dimensional and displacement deviations, resulting in low efficiency and poor precision, thus affecting production efficiency.

[0003] In summary, the existing steel cage manufacturing process relies heavily on manual adjustment, which leads to technical problems such as easy dimensional and displacement deviations and low production efficiency. Utility Model Content

[0004] This utility model aims to solve the technical problem that the existing steel cage manufacturing process relies heavily on manual adjustment, which easily leads to dimensional and displacement deviations and low production efficiency. Therefore, it provides a jig for processing precast square culvert steel cages, which includes a support base and a limiting component. The limiting component includes a transverse fixing tube, a longitudinal fixing tube, a vertical tube, an L-shaped tube, a first positioning steel bar, and a second positioning steel bar.

[0005] The horizontal fixing pipe is fixedly installed horizontally on the bottom surface of the support base, the longitudinal fixing pipe is fixedly installed horizontally on the bottom surface of the horizontal fixing pipe, and the vertical pipe is installed vertically on the top surface of the support base. The vertical pipe can rotate in the horizontal circumferential direction. The side ends of both the horizontal and longitudinal fixing pipes can be connected to L-shaped pipes. Multiple first positioning steel bars are evenly installed on the L-shaped pipes along the longitudinal direction, and multiple second positioning steel bars are evenly installed on the vertical pipes along the longitudinal direction. The L-shaped pipes and the vertical pipes are used to limit the wall thickness of the precast square culvert steel cage.

[0006] As another improvement of this utility model, the number of L-shaped tubes is 4n, where the value of n is 1, 2 or 3, and the outer contour shape of the 4n L-shaped tubes is rectangular. The outer contour shape of the 4n L-shaped tubes is used to match the shape of the precast culvert steel cage.

[0007] As another improvement of this utility model, the value of n is 2, there are 2 horizontal fixing pipes arranged along the horizontal longitudinal direction, 2 longitudinal fixing pipes arranged along the horizontal transverse direction, and 8 L-shaped pipes. Supporting steel bars are installed between every 2 L-shaped pipes arranged along the side length of the rectangle.

[0008] As another improvement of this utility model, the limiting component also includes a limiting long bolt, which is installed between two oppositely arranged supporting steel bars, and there are two limiting bolts.

[0009] As another improvement of this utility model, the support base includes a base platform and support legs. The support legs are installed at the bottom of the four corners of the base platform, and the horizontal fixing tube is horizontally fixedly installed on the bottom surface of the base platform.

[0010] As another improvement of this utility model, both the transverse fixing tube and the longitudinal fixing tube are fitted onto the outside of the L-shaped tube, and the inner wall dimensions of both the transverse fixing tube and the longitudinal fixing tube are the same as the outer wall dimensions of the L-shaped tube.

[0011] As another improvement of this utility model, the longitudinal fixing tube is fixedly installed on the bottom surface of the transverse fixing tube by welding along the horizontal longitudinal direction.

[0012] As another improvement of this utility model, the spacing of the plurality of first positioning steel bars is the same as the vertical spacing of the reinforcing steel bars of the precast culvert steel cage, and the spacing of the plurality of second positioning steel bars is the same as the vertical spacing of the reinforcing steel bars of the precast culvert steel cage.

[0013] As another improvement of this utility model, a sleeve is fixedly installed on the top surface of the support base, and the vertical tube is rotatably installed inside the sleeve along the horizontal circumferential direction.

[0014] As another improvement of this utility model, a sleeve is fixedly installed on the top surface of the support base by welding.

[0015] The beneficial effects of this utility model are:

[0016] 1. The L-shaped tube and vertical tube of this utility model are used to limit the wall thickness of the precast square culvert steel cage. The L-shaped tube and vertical tube, together with the first positioning steel bar and the second positioning steel bar, can effectively limit the size and displacement deviation of the steel cage, realize precise control of the steel bar spacing, and improve the forming quality of the steel cage.

[0017] 2. The sliding L-shaped tube facilitates the hoisting process after the steel cage is tied, improving hoisting efficiency.

[0018] 3. The position of the L-shaped tube can be adjusted by the support steel bars and the limiting bolts, thereby adjusting the wall thickness of the steel cage. It can adapt to the binding of steel cages of different sizes, realize multiple uses of one frame, and improve binding efficiency. Attached Figure Description

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. In the description of this utility model, it should be noted that the positional relationships indicated by terms such as "horizontal," "vertical," "first," and "second" are only based on the positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model, and do not indicate or imply that the referred components have a specific orientation, or are constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Specific implementation method one: Combining Figure 1 This embodiment describes a jig for processing precast square culvert steel cages, which includes a support base 1 and a limiting component. The limiting component includes a transverse fixing pipe 2, a longitudinal fixing pipe 3, a vertical pipe 4, an L-shaped pipe 5, a first positioning steel bar 6, and a second positioning steel bar 7.

[0022] The horizontal fixing pipe 2 is fixedly installed horizontally on the bottom surface of the support base 1, the longitudinal fixing pipe 3 is fixedly installed horizontally on the bottom surface of the horizontal fixing pipe 2, and the vertical pipe 4 is installed vertically on the top surface of the support base 1. The vertical pipe 4 can rotate in the horizontal circumferential direction. The side ends of both the horizontal fixing pipe 2 and the longitudinal fixing pipe 3 can be connected to L-shaped pipes 5. Multiple first positioning steel bars 6 are evenly installed in the longitudinal direction of the L-shaped pipe 5, and multiple second positioning steel bars 7 are evenly installed in the longitudinal direction of the vertical pipe 4. The L-shaped pipe 5 and the vertical pipe 4 are used to limit the wall thickness of the precast square culvert steel cage.

[0023] During implementation, the jig is assembled, and the L-shaped tube is moved to the appropriate position according to the designed steel cage dimensions;

[0024] L-shaped tubes are used in conjunction with vertical tubes to limit the wall thickness of precast culvert steel cages. The L-shaped tubes and vertical tubes, together with the first and second positioning steel bars, can effectively limit the size and displacement deviation of the steel cage, and achieve precise control of the steel bar spacing. The steel cage is then manually tied or welded to obtain the basic skeleton of the steel cage. The distribution steel bars and structural steel bars are then welded onto the steel cage skeleton according to the design spacing, and the steel cage is completed.

[0025] The hoisting of the reinforcing cage requires hoisting tools such as a gantry crane to first lift the reinforcing cage a short distance to relieve the pressure on the first and second positioning reinforcing bars. Depending on the size of the reinforcing cage and the site, the vertical pipe is rotated, the horizontal outward movement is made, or an L-shaped pipe is used to prevent the first and second positioning reinforcing bars from interfering with the overall hoisting of the precast culvert reinforcing cage. The precast culvert reinforcing cage is then hoisted out as a whole and transported to the precast culvert formwork.

[0026] Specific Implementation Method Two: Combining Figure 1 This embodiment differs from Specific Embodiment 1 in that the number of L-shaped pipes 5 is 4n, where n is 1, 2, or 3. The outer contour shape of the 4n L-shaped pipes 5 is rectangular, and this shape is used to match the shape of the precast culvert reinforcement cage. This design aims to maintain the overall stability of the device. Other components and connection methods are the same as in Specific Embodiment 1.

[0027] Specific implementation method three: Combining Figure 1 This embodiment differs from specific embodiment one in that the value of n is 2. There are two transverse fixing pipes 2 arranged along the horizontal longitudinal direction, two longitudinal fixing pipes 3 arranged along the horizontal transverse direction, and eight L-shaped pipes 5. Supporting steel bars 8 are installed between every two L-shaped pipes 5 arranged along the side length of the rectangle. The purpose of this design is to maintain the overall stability of the device while saving material costs and improving construction efficiency. Other components and connection methods are the same as in specific embodiment one or two.

[0028] Specific implementation method four: Combination Figure 1 This embodiment differs from specific embodiment one in that the limiting component also includes a limiting long bolt 9, which is installed between two opposing supporting reinforcing bars 8. The limiting long bolt makes it easier to maintain the stability of the L-shaped tube during the reinforcing bar binding process. Other components and connection methods are the same as any one of specific embodiments one to three.

[0029] Specific Implementation Method Five: Combining Figure 1 This embodiment differs from specific embodiment one in that the support base 1 includes a base platform and support legs. The support legs are installed at the bottom of the four corners of the base platform, and the horizontal fixing tube 2 is fixedly installed horizontally on the bottom surface of the base platform. Other components and connection methods are the same as any one of specific embodiments one to four.

[0030] Specific Implementation Method Six: Combination Figure 1This embodiment differs from specific embodiment one in that both the transverse fixing tube 2 and the longitudinal fixing tube 3 are fitted onto the outside of the L-shaped tube 5, and the inner wall dimensions of the transverse fixing tube 2 and the longitudinal fixing tube 3 are the same as the outer wall dimensions of the L-shaped tube 5. The purpose of this design is to achieve static friction between the inner walls of the transverse fixing tube 2 and the longitudinal fixing tube 3 and the outer wall of the L-shaped tube 5, allowing the L-shaped tube to slide horizontally under a horizontal external force. After the horizontal external force is removed, the transverse fixing tube and the longitudinal fixing tube can still provide a certain degree of restraint on the L-shaped tube through static friction. Other components and connection methods are the same as any one of specific embodiments one to five.

[0031] Specific implementation method seven: Combination Figure 1 This embodiment differs from specific embodiment one in that the longitudinal fixing pipe 3 is fixedly installed on the bottom surface of the transverse fixing pipe 2 along the horizontal longitudinal direction by welding. Welding is a simple, reliable, and easy-to-construct method. Other components and connection methods are the same as any one of specific embodiments one through six.

[0032] Specific implementation method eight: Combination Figure 1 This embodiment differs from specific embodiment one in that the spacing of the plurality of first positioning reinforcing bars 6 is the same as the vertical spacing of the reinforcing bars in the precast culvert reinforcement cage, and the spacing of the plurality of second positioning reinforcing bars 7 is the same as the vertical spacing of the reinforcing bars in the precast culvert reinforcement cage. This design ensures the manufacturing accuracy of the reinforcement cage. Other components and connection methods are the same as any one of specific embodiments one through seven.

[0033] Specific Implementation Method Nine: Combining Figure 1 This embodiment differs from specific embodiment one in that a sleeve 10 is fixedly installed on the top surface of the support base 1, and the vertical tube 4 is rotatably installed inside the sleeve 10 along the horizontal circumferential direction. This design results in a simple and reliable structure. Other components and connection methods are the same as in any one of specific embodiments one through eight.

[0035] Combination Figure 1 Explanation of the working principle of this utility model:

[0036] During implementation, the jig is assembled, and the L-shaped tube is moved to a suitable position according to the designed steel cage size. The L-shaped tube is then limited by the limiting bolts and supporting steel bars.

[0037] L-shaped tubes are used in conjunction with vertical tubes to limit the wall thickness of precast culvert steel cages. The L-shaped tubes and vertical tubes, together with the first and second positioning steel bars, can effectively limit the size and displacement deviation of the steel cage, and achieve precise control of the steel bar spacing. The steel cage is then manually tied or welded to obtain the basic skeleton of the steel cage. The distribution steel bars and structural steel bars are then welded onto the steel cage skeleton according to the design spacing, and the steel cage is completed.

[0038] The hoisting of the reinforcing cage requires hoisting tools such as a gantry crane to first lift the reinforcing cage a short distance to relieve the pressure on the first and second positioning reinforcing bars. Depending on the size of the reinforcing cage and the site, the vertical pipe is rotated, the horizontal outward movement is made, or an L-shaped pipe is used to prevent the first and second positioning reinforcing bars from interfering with the overall hoisting of the precast culvert reinforcing cage. The precast culvert reinforcing cage is then hoisted out as a whole and transported to the precast culvert formwork.
