Description

Technical Field

[0001] The utility model relates to the field of high-speed magnetic suspension track construction, in particular to a temporary connection structure of an anchor plate. Background Art

[0002] Track beams are a crucial component of maglev tracks. They are beam- or plate-type structures that serve as the functional surface of the track, bearing train loads and transferring them to the supporting structure. Compared to traditional rail trains, maglev trains require even higher precision in track beams.

[0003] In the existing technology, the applicant in this case was the first to propose a new maglev track beam structure, and previously applied for patents such as "Track beam structure and forming method for ultra-high-speed maglev track test section" and "A prefabricated maglev track beam"; in this type of existing technology, the idea of ​​pre-embedded sleeves during on-site casting was proposed to facilitate the connection of subsequent magnet modules.

[0004] However, as the research continued to deepen, the applicant discovered that when assembling the magnet module in the suspension groove, the width of the suspension groove was too narrow to be convenient for construction, and the magnet module was prone to more friction and collision with the groove wall, which was not conducive to the protection of the magnet module. Based on this, the applicant proposed a method of setting anchor plates in the groove wall of the suspension groove and the area around the sleeve, and embedding the metal anchor plates in the groove wall to reduce the direct friction and collision between the magnet module and the concrete. However, if the anchor plate and the groove wall of the suspension groove are to be molded together, the anchor plate needs to be temporarily connected to the template of the suspension groove side mold, and the connection between the anchor plate and the side mold needs to be released during demoulding. There is no dedicated structure for this in the prior art, which makes it inconvenient to operate. Utility Model Content

[0005] The purpose of the utility model is to provide a temporary connection structure for an anchor plate, so as to solve the problem in the prior art that it is inconvenient to separate the side formwork from the anchor plate after the waiting for solidification is completed, so as to facilitate the temporary connection and disassembly between the anchor plate and the side formwork and facilitate the pre-installation of the anchor plate.

[0006] The utility model is achieved through the following technical solutions:

[0007] A temporary connection structure for an anchor plate includes a side formwork template, the inner wall of the side formwork template is detachably connected to the anchor plate, and a first seal is arranged between the anchor plate and the side formwork template; a plurality of positioning grooves are provided on the outer wall of the anchor plate, and a positioning through hole is provided on the side formwork template facing the positioning grooves; and also includes a connecting component that passes through the positioning through hole and is inserted into the positioning groove, and the connecting component is used to connect the anchor plate.

[0008] To address the problem in the prior art of making it difficult to separate the side formwork from the anchor plate after the set period, the present invention proposes a temporary anchor plate connection structure. The present invention connects the anchor plate to the inner wall of the side formwork, allowing the anchor plate and side formwork to be detachably connected. A first seal prevents concrete from seeping in between the anchor plate and the side formwork and being solidified.

[0009] Those skilled in the art should understand that the inner wall of the side formwork in this application refers to the side wall of the side formwork facing the casting direction, that is, the side wall facing the center of the suspension trough; similarly, the outer wall of the side formwork refers to the side wall of the side formwork facing away from the casting direction, that is, the side wall facing away from the center of the suspension trough.

[0010] When the present application is used specifically, the anchor plate is connected to the side formwork before pouring concrete on the suspended trough wall, and then the normal pouring of the suspended trough wall is carried out; after the concrete is solidified, the connection between the anchor plate and the side formwork is released, the side formwork is removed, the anchor plate is fixed in the concrete, and the anchor plate can be directly embedded in the trough wall of the suspended trough, thereby achieving the purpose of synchronously completing the construction of the anchor plate during the forming process of the suspended trough, solving the problem of difficulty in later installation caused by the narrow horizontal space in the suspended trough, and facilitating the temporary connection and disassembly between the anchor plate and the side formwork.

[0011] Furthermore, the connecting assembly includes a positioning cylinder for inserting into the positioning through hole and the positioning groove, the bottom of the positioning cylinder is radially slidably fitted with a positioning block, the side wall of the positioning cylinder is provided with a notch facing the positioning block; the groove wall of the positioning groove is provided with an accommodating space opposite to the notch, and the accommodating space is used to accommodate the positioning block; and it also includes a starting mechanism for driving the positioning block to slide radially.

[0012] When this solution is used, the positioning cylinder is inserted into the positioning through hole until it abuts against the bottom of the positioning groove, and then the starting mechanism drives each positioning block to slide radially outward so that each positioning block slides into the corresponding notch. Due to the limitation of the notch, the positioning block cannot move along the axial direction of the positioning cylinder, and thus the positioning cylinder cannot automatically fall off once inserted, thereby ensuring that the anchor plate cannot fall off automatically, realizing a stable temporary connection of the anchor plate, and the connection structure operates from the outside of the side formwork and acts on the inside of the anchor plate, and will not interfere with the consolidation between the anchor plate and the concrete, which is conducive to the temporary connection of the anchor plate in a narrow space and significantly improves the construction convenience.

[0013] Furthermore, a mounting block is provided at the bottom of the positioning cylinder, and a plurality of positioning blocks are evenly distributed outside the mounting block in an annular shape; an elastic member is connected between the mounting block and the positioning block, and the elastic member is connected between the bottom of the mounting groove and the mounting block.

[0014] This solution uses mounting blocks to provide connection points for the elastic members, ensuring that each positioning block is constantly subjected to radially inward tension. This arrangement allows each positioning block to automatically retract and reset after the starter mechanism is removed, facilitating the removal of the formwork after the set period is complete. Furthermore, after the starter mechanism is inserted, each positioning block clamps the starter mechanism, helping to maintain its stable position. Furthermore, the provision of mounting slots in this solution facilitates the full inward retraction of each positioning block, making the release of the anchor plate and side formwork more stable and convenient.

[0015] Furthermore, the elastic member is a tension spring, that is, a spring that always provides tension.

[0016] Furthermore, the starting mechanism includes a starting pin for inserting into the interior of the positioning cylinder, a reduced diameter portion is provided at one end of the starting pin, and a pin cap is provided at the other end; a push slope matching the reduced diameter portion is provided on the side surface of the positioning block facing the barrel mouth of the positioning cylinder, and the push slope is gradually inclined toward the bottom of the positioning cylinder from the outside to the inside along the radial direction.

[0017] In this solution, the starter pin, with its reduced diameter portion facing inward, is inserted into the positioning cylinder. The reduced diameter portion squeezes between the positioning blocks. As the starter pin penetrates deeper, the positioning blocks are pushed outward, causing them to slide radially outward. The presence of the push-up slope facilitates the insertion of the reduced diameter portion between the positioning blocks, reducing the risk of the starter pin becoming stuck.

[0018] Furthermore, the outer wall of the positioning cylinder is provided with an external thread, and the inner wall of the pin cap is provided with an internal thread matching the external thread. The starter pin is preferably screwed in by rotation rather than by linear motion, so that the pin cap gradually fits over the outer surface of the positioning cylinder and forms a threaded engagement. The threads prevent the starter pin from automatically falling out, thereby ensuring a stable connection to the anchor plate.

[0019] Furthermore, a nut matching the positioning cylinder is also included. In this solution, before the start pin is installed, the nut can be screwed into the outside of the positioning cylinder but not tightened temporarily. After the start pin is screwed into place, the nut can be tightened to significantly improve the connection stability.

[0020] Furthermore, a first through hole is provided on the side mold template, and a second through hole is provided on the anchor plate facing the first through hole, and the aperture of the first through hole is larger than the aperture of the second through hole.

[0021] The first through hole facilitates the subsequent insertion of the sleeve to be installed from the outside of the side form template; this operation method can avoid the problem of the sleeve being easily bumped and damaged due to the narrow working space when the sleeve is installed in advance and then the side form template is put into place.

[0022] Preferably, the first through hole and the second through hole are coaxial.

[0023] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0024] 1. The utility model provides a temporary connection structure for anchor plates, which realizes the purpose of completing the construction of anchor plates simultaneously during the formation process of suspension troughs, solves the problem of difficulty in later installation caused by the narrow horizontal space in the suspension trough, and facilitates the temporary connection and disassembly between the anchor plates and the side formwork.

[0025] 2. The utility model provides a temporary connection structure for anchor plates, which is conducive to the temporary connection of anchor plates in narrow spaces and significantly improves the convenience of construction. BRIEF DESCRIPTION OF THE DRAWINGS
