Description
Technical Field
[0001] This utility model relates to the technical field of railway bridge pier formwork structure, specifically a railway bridge pier formwork with rapid positioning function. Background Technology
[0002] A railway bridge abutment is a reinforced concrete platform located on top of the foundation piles. It is mainly used to bear and distribute the loads transmitted by the pier body and is an important component of the railway bridge structure. Formwork is an indispensable temporary support structure in the construction of railway bridge abutments. It can shape the abutment into its designed shape and size and ensure the integrity of the concrete pouring process.
[0003] Current railway bridge abutment formwork is often installed directly on the formwork structure. During installation, users need to repeatedly determine and adjust the horizontal and vertical level of the formwork structure using a calibrator. This makes it difficult for the device to perform horizontal calibration and positioning operations. Furthermore, the railway bridge abutment is poured directly against the inner wall of the formwork structure, which can easily lead to excessive adhesion between the formwork and the railway bridge abutment casting, making it difficult to recycle. To address these issues, we propose a new type of railway bridge abutment formwork with a rapid positioning function. Utility Model Content
[0004] The purpose of this utility model is to provide a railway bridge abutment template with a rapid positioning function, so as to solve the problems mentioned in the background art, such as the difficulty in quickly calibrating and positioning the horizontal and vertical positions of the template and the easy adhesion between the template and the railway bridge abutment casting.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a railway bridge abutment template with rapid positioning function, comprising a horizontal transverse assembly template, with horizontal longitudinal assembly templates installed at both ends of the horizontal transverse assembly template, longitudinal base plates evenly arranged on the horizontal longitudinal assembly template, and transverse base plates evenly arranged on the horizontal transverse assembly template. Installation slides are provided at the edges of the outer walls of the transverse and longitudinal base plates, and external insertion arms are slidably connected between adjacent installation slides. Installation grooves are provided on the external insertion arms. Rubber sealing films are installed on both the horizontal transverse and horizontal longitudinal assembly templates. Fixed and movable pre-embedded positioning piles matching the installation grooves are sequentially installed below both the horizontal transverse and horizontal longitudinal assembly templates. Upper positioning sleeves are respectively provided on the fixed and movable pre-embedded positioning piles, and calibration gauges are inserted between adjacent upper positioning sleeves. A sleeve arm is clamped at one end of the movable pre-embedded positioning pile, and a detachable hydraulic telescopic cylinder is installed at the bottom end of the sleeve arm. A controller is installed on the outer wall of the detachable hydraulic telescopic cylinder.
[0006] As a further technical solution of this utility model, a clamping cylinder is fixed on the mounting groove.
[0007] As a further technical solution of this utility model, the top of both the fixed pre-embedded positioning pile and the dynamic pre-embedded positioning pile is provided with a clamping post that matches the clamping cylinder.
[0008] As a further technical solution of this utility model, both the mounting post and the mounting cylinder are provided with locking screw holes.
[0009] As a further technical solution of this utility model, mud flow holes are uniformly provided at the bottom edges of the fixed pre-embedded positioning pile and the moving pre-embedded positioning pile, and hollow cavities matching the mud flow holes are provided inside the fixed pre-embedded positioning pile and the moving pre-embedded positioning pile.
[0010] As a further technical solution of this utility model, the rubber sealing film is uniformly provided with limiting protrusions, and the horizontal transverse assembly template and the horizontal longitudinal assembly template are both provided with concave holes that match the limiting protrusions.
[0011] As a further technical solution of this utility model, the sleeve arm and the movable pre-embedded positioning pile form a snap-fit connection, and a screw is provided between the sleeve arm and the movable pre-embedded positioning pile.
[0012] As a further technical solution of this utility model, the bottom of the detachable hydraulic telescopic cylinder is provided with a fixed base, and mounting holes are evenly provided on the edge of the fixed base.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] By incorporating installation sliding strips, the device optimizes its structure. Firstly, based on the horizontal and vertical lengths of the railway bridge pier to be constructed, the user can utilize the sliding connection between the installation sliding strips and installation grooves to select an appropriate number of horizontal base plates and assemble them into a horizontal horizontal assembly template using corresponding external insertion arms. Similarly, an appropriate number of vertical base plates can be assembled into a horizontal longitudinal assembly template using corresponding external insertion arms. This allows the device to achieve modular assembly advantages, facilitating flexible adjustment of the template structure size. Secondly, the user can use four pre-determined reference points at the railway bridge pier construction location to assemble fixed and movable pre-embedded positioning piles at both ends of the horizontal and vertical axes. Specifically, the fixed pre-embedded positioning piles are first fixed to the ground with cement. Then, a calibration gauge is inserted into the upper positioning sleeve of the fixed pre-embedded positioning pile. Calibration gauges are also inserted between adjacent upper positioning sleeves. Finally, the movable pre-embedded positioning pile is fitted onto the other end of the calibration gauge. The movable and fixed pre-embedded positioning piles are then visually adjusted according to the scale on the calibration gauge. The distance is used to determine the horizontal position of the dynamic pre-embedded positioning pile. Then, the detachable hydraulic telescopic cylinder is activated, and the dynamic pre-embedded positioning pile installed with it is automatically raised and lowered through the sleeve arm. With the help of the electronic calibrator placed in front of the calibration ruler, the installation height of the dynamic pre-embedded positioning pile is automatically positioned, ensuring that the dynamic and fixed pre-embedded positioning piles are at the same level. This solves the problems of template lateral deviation and poor stability caused by uneven ground. Cement is then poured in to seal the dynamic pre-embedded positioning pile and the bottom surface. The detachable hydraulic telescopic cylinder is removed from the dynamic pre-embedded positioning pile through the installation structure composed of screws and the sleeve arm, and can be used for the next set of calibration structures. This makes the device easy to automatically calibrate and position, eliminating the need for manual adjustment of the positioning based on the detection function of the electronic calibrator before the installation of the fixed pile structure and the ground. This improves the convenience of operation and realizes the function of rapid positioning. When actually installing the fixed pile structure, the user can pour cement into the top of the fixed and dynamic pre-embedded positioning piles, and evenly introduce it into the ground embedment through the mud flow hole to achieve reinforcement, prevent collapse, and achieve high stability.
[0015] By installing horizontal and vertical assembly templates, the user can utilize the locking action between the limiting protrusions and the corresponding recesses on the horizontal and vertical assembly templates during operation. Sealing pads of corresponding areas are then assembled on the inner surfaces of both templates, improving the sealing effect of the inner walls of the cavity after assembly. This prevents slurry leakage during subsequent pouring of railway bridge piers. Furthermore, the rubber sealing film directly adheres to the molded railway bridge pier casting body, preventing cement from directly contacting the template structure after pouring cement, which could lead to difficulty in separation. This facilitates subsequent demolding and separation of the template structure, increasing flexibility and ease of operation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] Please see Figure 1-5An embodiment of this utility model is provided: a railway bridge abutment template with a rapid positioning function, including a horizontal transverse assembly template 8, with horizontal longitudinal assembly templates 9 installed at both ends of the horizontal transverse assembly template 8, with longitudinal base plates 5 evenly arranged on the horizontal longitudinal assembly template 9, and transverse base plates 2 evenly arranged on the horizontal transverse assembly template 8.
[0024] Mounting slides 18 are provided at the edges of the outer walls of the horizontal substrate 2 and the vertical substrate 5. An external insertion arm 1 is slidably connected between adjacent mounting slides 18. A mounting groove 7 is provided on the external insertion arm 1.
[0025] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, based on the horizontal and longitudinal lengths of the railway bridge abutment to be constructed, the user can utilize the sliding connection between the mounting strip 18 and the mounting groove 7 to select an appropriate number of transverse base plates 2 and assemble them into a horizontal transverse assembly template 8 through the corresponding external insertion arm 1, and select an appropriate number of longitudinal base plates 5 and assemble them into a horizontal longitudinal assembly template 9 through the corresponding external insertion arm 1. This enables the device to achieve the advantages of modular assembly, making it easy to flexibly adjust the size of the template structure and making it highly applicable.
[0026] Below the horizontal transverse assembly template 8 and the horizontal longitudinal assembly template 9, fixed pre-embedded positioning piles 4 and movable pre-embedded positioning piles 17 that match the installation slide 7 are installed in sequence. Upper positioning sleeves 11 are respectively set on the fixed pre-embedded positioning piles 4 and the movable pre-embedded positioning piles 17. A calibration ruler 19 is inserted between adjacent upper positioning sleeves 11. A sleeve arm 13 is clamped at one end of the movable pre-embedded positioning pile 17. A detachable hydraulic telescopic cylinder 16 is installed at the bottom end of the sleeve arm 13. A controller 21 is installed on the outer wall of the detachable hydraulic telescopic cylinder 16.
[0027] A mounting cylinder 3 is fixed on the mounting groove 7;
[0028] Both the fixed pre-embedded positioning pile 4 and the dynamic pre-embedded positioning pile 17 are equipped with a clamping column 14 that matches the clamping cylinder 3 at the top.
[0029] Both the mounting post 14 and the mounting cylinder 3 are provided with locking screw holes 15;
[0030] Mud flow holes 12 are evenly provided at the bottom edges of the fixed pre-embedded positioning pile 4 and the movable pre-embedded positioning pile 17, and hollow cavities matching the mud flow holes 12 are provided inside the fixed pre-embedded positioning pile 4 and the movable pre-embedded positioning pile 17.
[0031] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, the user can assemble the fixed pre-embedded positioning piles 4 and the movable pre-embedded positioning piles 17 at the four reference points of the pre-determined railway bridge abutment construction location, corresponding to the horizontal transverse ends and the horizontal longitudinal ends. Specifically, the fixed pre-embedded positioning piles 4 are first fixed to the ground with cement. Then, a calibration ruler 19 is inserted into the upper positioning sleeve 11 of the fixed pre-embedded positioning pile 4. The calibration ruler 19 is inserted between adjacent upper positioning sleeves 11. The movable pre-embedded positioning pile 17 is then fitted onto the other end of the calibration ruler 19. The distance between the movable pre-embedded positioning pile 17 and the fixed pre-embedded positioning pile 4 is adjusted visually according to the scale on the calibration ruler 19 to determine the horizontal position of the movable pre-embedded positioning pile 17. Then, the detachable hydraulic telescopic cylinder 16 is activated, which drives the movable pre-embedded positioning pile 17 installed therewith to automatically rise and fall through the sleeve arm 13. With the help of the electronic calibration instrument placed in front of the calibration ruler 19, the movement is automatically... The installation height of the movable pre-embedded positioning pile 17 is accurately positioned to ensure that the movable pre-embedded positioning pile 17 and the fixed pre-embedded positioning pile 4 are at the same level. This solves the problems of template lateral deviation and poor stability caused by uneven ground. Cement is then poured in to seal the movable pre-embedded positioning pile 17 and the bottom surface. The installation structure consisting of screws and sleeve arm 13 allows the detachable hydraulic telescopic cylinder 16 to be removed from the movable pre-embedded positioning pile 17 for use in the next set of calibration structures. This makes the device easy to automate calibration and positioning, eliminating the need for manual adjustment based on the detection function of the electronic calibrator before the installation of the fixed pile structure and the ground can be achieved. This improves the convenience of operation and realizes the function of rapid positioning. When actually installing the fixed pile structure, the user can pour cement into the top of the fixed pre-embedded positioning pile 4 and the movable pre-embedded positioning pile 17, and evenly introduce it into the ground embedment through the mud flow hole 12 to achieve reinforcement, prevent collapse, and achieve high stability.
[0032] Limiting protrusions 10 are evenly provided on the rubber sealing film 6, and concave holes matching the limiting protrusions 10 are provided on both the horizontal transverse assembly template 8 and the horizontal longitudinal assembly template 9.
[0033] Specifically, such as Figure 2 and Figure 3 As shown, users can utilize the interlocking action between the limiting protrusion 10 and the corresponding recesses on the horizontal transverse assembly template 8 and the horizontal longitudinal assembly template 9 to assemble rubber sealing films 6 of corresponding areas on the inner surfaces of both the horizontal transverse assembly template 8 and the horizontal longitudinal assembly template 9. This improves the sealing effect of the inner wall of the cavity of the template structure after the horizontal longitudinal assembly template 9 and the horizontal transverse assembly template 8 are assembled, avoiding the problem of mud leakage during the subsequent pouring of railway bridge abutments. Moreover, the rubber sealing film 6 is directly bonded to the molded railway bridge abutment casting body, which also avoids excessive adhesion between the horizontal transverse assembly template 8 and the horizontal longitudinal assembly template 9 and the railway bridge abutment casting body, making the template structure difficult to disassemble and recycle, thus improving the convenience of operation.
[0034] The sleeve arm 13 and the movable pre-embedded positioning pile 17 are connected by a snap-fit mechanism, and screws are provided between the sleeve arm 13 and the movable pre-embedded positioning pile 17.
[0035] The bottom of the detachable hydraulic telescopic cylinder 16 is provided with a fixed base 20, and mounting holes are evenly provided on the edge of the fixed base 20.
[0036] Working principle: In use, firstly, based on the horizontal and longitudinal lengths of the railway bridge pier to be constructed, the user can utilize the sliding connection between the mounting strip 18 and the mounting groove 7 to select an appropriate number of transverse base plates 2 and assemble them into a horizontal transverse assembly template 8 through the corresponding external insertion arm 1. Similarly, an appropriate number of longitudinal base plates 5 can be selected and assembled into a horizontal longitudinal assembly template 9 through the corresponding external insertion arm 1. This allows the device to achieve the advantages of modular assembly, facilitating flexible adjustment of the template structure size. Simultaneously, the user can use the four pre-determined reference points of the railway bridge pier construction location to assemble the fixed pre-embedded positioning piles 4 and the movable pre-embedded positioning piles 17 located at both ends of the horizontal and longitudinal directions. Specifically, the fixed pre-embedded positioning piles 4 are first... The fixed anchor is cemented to the ground. A calibration ruler 19 is inserted into the upper positioning sleeve 11 of the fixed anchor 4. Calibration rulers 19 are inserted between adjacent upper positioning sleeves 11. The other end of the calibration ruler 19 is then fitted onto the movable anchor 17. The distance between the movable anchor 17 and the fixed anchor 4 is visually adjusted according to the scale on the calibration ruler 19 to determine the horizontal position of the movable anchor 17. Next, the detachable hydraulic telescopic cylinder 16 is activated, and the movable anchor 17 is automatically raised and lowered via the sleeve arm 13. This, combined with the electronic calibration instrument placed in front of the calibration ruler 19, automatically positions the movable anchor 17 at the correct installation height, ensuring the proper alignment of the movable anchor 17 and the fixed anchor 4. By placing the devices at the same horizontal level, the problems of template lateral deviation and poor stability caused by uneven ground are solved. Cement is then poured in to seal the dynamic pre-embedded positioning pile 17 and its bottom surface. Using an installation structure consisting of screws and a sleeve arm 13, a detachable hydraulic telescopic cylinder 16 can be removed from the dynamic pre-embedded positioning pile 17 for use in the next calibration structure. This facilitates automated calibration and positioning, eliminating the need for repeated manual adjustments based on the electronic calibrator's detection before the installation of the fixed pile structure and the ground. This improves operational convenience and enables rapid positioning. During actual installation of the fixed pile structure, the user can pour cement into the top of the fixed pre-embedded positioning pile 4 and the dynamic pre-embedded positioning pile 17, and then evenly guide it into the ground embedment opening through the mud distribution hole 12. The system is reinforced and prevents collapse, offering high stability. Furthermore, users can utilize the interlocking action between the limiting protrusions 10 and the corresponding recesses on the horizontal transverse assembly templates 8 and 9 to assemble rubber sealing films 6 of corresponding areas on the inner surfaces of both templates. This improves the sealing effect of the inner walls of the cavity in the assembled template structure, preventing slurry leakage during subsequent pouring of the railway bridge abutment. Moreover, the rubber sealing film 6 directly adheres to the molded railway bridge abutment casting, preventing excessive adhesion between the horizontal transverse assembly templates 8 and 9 and the railway bridge abutment casting, which would make the template structure difficult to disassemble and recycle.This improves the ease of operation.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
