Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for urban rail transit construction, specifically to a template suitable for a semi-circular ditch in urban rail track bed. Background Technology

[0002] In urban rail transit construction, the drainage system of the track bed is a key component to ensure the durability of the track structure and operational safety. Semi-circular drainage ditches are widely used in urban rail track bed drainage systems due to their structural stability and high drainage efficiency.

[0003] Currently, the construction of cast-in-place irrigation ditches commonly employs a combination of customized steel formwork and support systems. However, existing support systems and formwork bodies are mostly fixed connections or only offer minor height adjustments. When assembling multiple formwork panels, workers must first align adjacent formwork bodies before fixing the support system to the rails. Once the support system is secured, if gaps or misalignments are found at the interfaces of adjacent formwork bodies, the formwork positions must be readjusted and reinstalled. This repeated disassembly and reinstallation process not only significantly reduces construction efficiency and severely impacts the construction period but also easily introduces new installation errors in complex construction environments, thus affecting the quality of concrete pouring. Utility Model Content

[0004] The purpose of this utility model is to provide a template suitable for semi-circular drainage ditches in urban rail transit tracks, so as to solve the problems of repeated disassembly and installation caused by gaps or misalignments at the interfaces of adjacent template bodies mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a template suitable for a semi-circular drainage ditch on an urban rail track bed, comprising a template body and a template infinitely adjustable support. The template body has a semi-circular structure. The template infinitely adjustable support includes a first support arm, a second support arm, a first limiting slot, a second limiting slot, a support rod, and an adjusting rod. The first and second support arms are spaced apart. The first limiting slot is located at one end of the first support arm, and the other end of the first support arm is connected to the rail. The second limiting slot is located at one end of the second support arm, and the other end of the second support arm is connected to the rail. The support rod is positioned near both ends in the first and second limiting slots, respectively, and the support rod can slide along its length to adjust its horizontal position. One end of the adjusting rod is connected to the support rod, and the other end of the adjusting rod is fixedly connected to the template body. The adjusting rod is used to adjust the height of the template body.

[0006] Furthermore, the first support arm includes a first sub-support arm, a second sub-support arm, and a support arm connecting plate. One end of the first sub-support arm is fixedly connected to the lower part of one side of the support arm connecting plate, and one end of the second sub-support arm is fixedly connected to the upper part of the other side of the support arm connecting plate. A first limiting slot is provided on the second sub-support arm.

[0007] Furthermore, an adjustment opening is provided on the end region of the first sub-support arm away from the support arm connecting plate. The first support arm also includes a limiting block and a bolt. The limiting block is fixedly installed on the end region of the first sub-support arm away from the support arm connecting plate, and the limiting block and the adjustment opening are spaced apart. The limiting block is located on one side of the rail, and the bolt passes through the adjustment opening and is threadedly connected to a nut. The bolt is located on the other side of the rail, so that the limiting block and the bolt are clamped and fixed to the rail together, thereby realizing the fixed connection between the first support arm and the rail.

[0008] Furthermore, the structure of the second support arm is the same as that of the first support arm.

[0009] Furthermore, the first limiting slot includes a first slot baffle and a second slot baffle. The first slot baffle and the second slot baffle are spaced apart on the second sub-support arm to form a slot structure for accommodating the support rod. The extension direction of the slot structure is perpendicular to the length direction of the second sub-support arm. The opening width of the slot structure is adapted to the width of the support rod so that the support rod can only slide along the extension direction of the first limiting slot.

[0010] Furthermore, the structure of the second limiting slot is the same as that of the first limiting slot, and the length direction of the first limiting slot is perpendicular to the length direction of the first support arm, while the length direction of the second limiting slot is perpendicular to the length direction of the second support arm.

[0011] Furthermore, the support rod has a through hole, which is set along the height direction of the support rod. One end of the adjusting rod is connected to the top surface of the template body, and the other end of the adjusting rod passes through the through hole and is threadedly connected to the nut.

[0012] Furthermore, the adjusting rod is a screw structure, and there are multiple adjusting rods.

[0013] Furthermore, the template also includes a first connecting part and a second connecting part. The first connecting part is located at one end of the template body, and the second connecting part is located at the other end of the template body. The first connecting part and the second connecting part are configured to be able to be inserted into each other so that multiple template bodies can be spliced ​​together.

[0014] This utility model has the following advantages over the prior art:

[0015] 1. This utility model creatively allows the support rod to slide horizontally by setting a limiting groove on the support arm and placing the support rod therein. This enables construction workers to quickly and accurately eliminate misalignments and gaps between templates and quickly eliminate misalignments and gaps between templates by setting a limiting groove on the support arm and placing the support rod therein after the entire support is secured to the rail. This greatly improves construction accuracy and efficiency.

[0016] 2. This utility model utilizes an adjusting rod design with a threaded rod and a nut. After horizontal positioning is achieved, rotating the nut drives the adjusting rod to perform precise axial lifting and lowering relative to the support rod, thereby realizing stepless fine-tuning of the template body in the vertical direction. This dual adjustment mechanism ensures that the template can be ultimately adjusted to the most ideal design position, providing a reliable guarantee for pouring a straight and accurately leveled ditch.

[0017] 3. This utility model transforms the complex overall disassembly and adjustment into simple local fine-tuning, avoiding damage to the support system caused by repeated disassembly. This not only shortens the adjustment time and reduces labor intensity, but also effectively reduces the cumulative error caused by multiple installations, thereby accelerating the overall construction progress and ultimately ensuring the quality of concrete pouring for the roadbed and drainage ditch.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] like Figures 1 to 5 As shown, an embodiment of this utility model provides a template suitable for a semi-circular drainage ditch on an urban rail track bed, including a template body 1 and a template infinitely adjustable support 2. The template body 1 has a semi-circular structure. The template infinitely adjustable support 2 includes a first support arm 3, a second support arm 4, a first limiting groove 9, a second limiting groove 10, a support rod 8, and an adjusting rod 5. The first support arm 3 and the second support arm 4 are spaced apart. The first limiting groove 9 is located at one end of the first support arm 3, and the other end of the first support arm 3 is connected to a rail. The second limiting groove 10 is located at one end of the second support arm 4, and the other end of the second support arm 4 is connected to a rail. The support rod 8 is located near both ends in the first limiting groove 9 and the second limiting groove 10, respectively, and the support rod 8 can slide along its length to adjust its horizontal position. One end of the adjusting rod 5 is connected to the support rod 8, and the other end of the adjusting rod 5 is fixedly connected to the template body 1. The adjusting rod 5 is used to adjust the height of the template body 1.

[0027] In this embodiment, the infinitely adjustable template support 2 enables precise and convenient bidirectional position adjustment of the template body 1 after it is fixed. By setting the two ends of the support rod 8 into the limiting slots of the two independent support arms, the support rod 8 can slide freely along its own length, thereby easily adjusting the lateral position of the template body 1 in the horizontal plane. At the same time, by connecting the support rod 8 and the template body 1 through the adjusting rod 5, the height of the template can be independently fine-tuned. By decoupling the horizontal adjustment and height adjustment functions of the template and integrating them into a stable and reliable rigid support system, the problem of needing to disassemble and adjust the entire template due to minor deviations in traditional construction is solved, greatly improving construction efficiency, adjustment accuracy, and ease of operation.

[0028] like Figure 2As shown, the template body 1 has a semi-circular structure. In this embodiment, it is made of corrosion-resistant steel plate by bending. The template body 1 can be divided into multiple splicable components. Each component is connected to each other through connectors to form a complete semi-circular structure with a radius of 125mm and a thickness of 2mm. Three connecting holes 13 are provided along the length of the top of the template body 1 for detachable fixed connection with the adjusting rod 5. The two ends of the template body 1 are respectively provided with a first connecting part 11 and a second connecting part 12, and vertical plates for fixed connection by bolts are provided at both ends of the upper surface of the template body 1. The first connecting part 11 has a convex structure, and the second connecting part 12 has a matching concave structure, enabling multiple template units to be quickly and accurately spliced ​​longitudinally to form a continuous template of the required length. The semi-circular structure made of bent steel plate has high strength and is not easily deformed, ensuring accurate dimensions of the drainage ditch and a smooth inner wall, which is conducive to smooth drainage. Its modular design allows the template to be flexibly spliced ​​according to the length requirements of the ditch through the insertion of the first connecting part 11 and the second connecting part 12. This design realizes the modularization and standardization of the template, which facilitates transportation, assembly and disassembly, improves construction efficiency, and adapts to the construction needs of ditches of different lengths. At the same time, the corrosion-resistant material ensures the service life of the template in harsh environments.

[0029] like Figure 4 As shown, the first support arm 3 includes a first sub-support arm 31, a second sub-support arm 32, and a support arm connecting plate 33. One end of the first sub-support arm 31 is fixedly connected to the lower part of one side of the support arm connecting plate 33, and one end of the second sub-support arm 32 is fixedly connected to the upper part of the other side of the support arm connecting plate 33, so that the first support arm 3 has an overall "Z" shaped structure, which enhances the bending stiffness and stability, effectively transfers the load during concrete pouring, and prevents deformation.

[0030] like Figure 3 As shown, the first support arm 3 and the second support arm 4 have the same structure, are parallel to each other and spaced apart, providing stable support. The first support arm 3 also includes a limiting block 6 and a bolt. The limiting block 6 is fixedly installed on the end of the first sub-support arm 31 away from the support arm connecting plate 33, and the limiting block 6 is spaced apart from the adjustment opening 7. The limiting block 6 is located on one side of the rail, and the bolt passes through the adjustment opening 7 and is threadedly connected to the nut. The bolt is located on the other side of the rail, so that the limiting block 6 and the bolt are clamped and fixed to the rail, thereby realizing the fixed connection between the first support arm 3 and the rail. The first support arm 3 connects the template body 1 and the rail, providing stable support for the template body 1, and integrates support and adjustment functions into one compact structure. Through its stepless adjustment characteristics, it completely overcomes the drawbacks of traditional fixed or finite-gradient adjustment supports, providing a foundation for high-precision construction.

[0031] In this embodiment, an adjustment opening 7 is provided at the end of the first sub-support arm 31 that connects to the rail. The length direction of the adjustment opening is consistent with the length direction of the first sub-support arm, providing physical space to accommodate adjustments for different types of rails. The limiting block 6 consists of two steel plates, both rectangular steel plates cut so that one side fits the bottom contour of the rail, and are welded at intervals to the top surface of that end of the first sub-support arm 31, maintaining a certain distance from the adjustment opening 7. A high-strength bolt with a diameter of 16mm passes through the adjustment opening 7 and is fixed with a nut at a position close to the rail. Working together with the limiting block 6, it secures the entire support frame to the rail, forming a reliable lock to ensure that the centerline position of the formed ditch meets the design requirements.

[0032] like Figure 4 As shown, the template infinitely adjustable bracket 2 also includes a first limiting slot 9 and a second limiting slot 10. The first limiting slot 9 is fixedly mounted on the second sub-support arm 32 of the first support arm 3, and the second limiting slot 10 is fixedly mounted on the second sub-support arm 32 of the second support arm 4. The first limiting slot 9 includes a first slot baffle 91 and a second slot baffle 92. The first slot baffle 91 and the second slot baffle 92 are spaced apart on the second sub-support arm 32 to form a slot structure for accommodating the support rod 8. The extension direction of the slot structure is perpendicular to the length direction of the second sub-support arm 32, and the opening width of the slot structure is adapted to the width of the support rod 8 so that the support rod 8 can only slide along the extension direction of the first limiting slot 9. The slot structure composed of the first slot baffle 91 and the second slot baffle 92 is simple to process, can effectively limit the degree of freedom of the support rod, prevent it from shifting due to vibration or force during construction, and enhance the reliability of the system. The limiting slot structure, through the parallel and spaced arrangement of the first slot baffle 91 and the second slot baffle 92, forms a guide channel perpendicular to the second sub-support arm 32. Its constraint support rod 8 can only slide horizontally, effectively preventing movement or swaying in any other direction. While providing flexible adjustment capability for the horizontal position of the formwork body 1, the rigid mechanical constraint greatly enhances the stability and reliability of the entire support system during adjustment and concrete pouring.

[0033] like Figure 3 As shown, the support rod 8 is made of high-strength steel square tubing. One end of the support rod 8 is set on the first limiting groove 9 of the first support arm 3, and the other end of the support rod 8 is set on the second limiting groove 10 of the second support arm 4. The support rod 8 is connected to the adjusting rod 5. The first limiting groove 9 and the second limiting groove 10 effectively limit the displacement of the support rod 9 along the length direction of the second sub-support arm 32, ensuring the stability of the support. As a transverse connecting rod connecting the adjusting rod 5 and the first support arm 3 and the second support arm 4, the support rod 8 evenly transmits the force of multiple adjusting points and jointly supports the template body 1.

[0034] In this embodiment, the adjusting rod 5 is a threaded rod structure, and the support rod 8 has a through hole. The adjusting rod 5 passes through the through hole, and a nut is screwed onto the end of the adjusting rod 5 away from the template body. The nut overlaps with the surface of the support rod 8 away from the template body. When height adjustment is required, rotating the nut can drive the template body 1 to rise or fall relative to the support rod 9, achieving stepless precision adjustment in the height direction.

[0035] In this embodiment, the template process for a semi-circular ditch on an urban rail track bed is as follows: First, the first support arm 3 and the second support arm 4 are initially fixed to the rail using limiting blocks 6 and bolts; then, the assembled template is connected to the support rod 8 via adjusting rod 5, and the support rod 8 is placed in the limiting slot; the height of the template body is adjusted by rotating the bolt at the top of the adjusting rod 5; multiple template units can be interlocked with each other via the first connecting part 11 and the second connecting part 12 of another template unit by horizontally sliding the support rod 8, thus assembling a template section of the required length; finally, when construction is completed, the support and template can be removed, cleaned, and transported to the next construction section for reuse.

[0036] In this embodiment, through the synergistic effect of the aforementioned structures, the adjustment flexibility, support stability, and construction accuracy of the formwork system are significantly improved compared to existing technologies. Its flexible horizontal adjustment can quickly and accurately eliminate misalignments and gaps between formwork panels, greatly improving construction accuracy and efficiency; the stepless height adjustment function perfectly adapts to the elevation requirements of different design standards for the construction ditch; the modular formwork design significantly improves assembly efficiency and versatility; and the selection of high-strength and corrosion-resistant materials ensures that the product can be reused repeatedly, has a long service life, and offers significant overall economic benefits. Ultimately, this device effectively ensures the forming quality of the ditch, improves construction efficiency, and reduces labor intensity.
