AI Technical Summary
Existing bridge formwork connection methods are inconvenient to assemble and disassemble as a whole, difficult to recycle, and the friction between the formwork and the connecting platform when clamped by the clamping plates causes vibration, affecting the fixing effect.
The design employs a combination of sliding adjustment base, telescopic column, bidirectional threaded rod, spherical arc groove, spherical slider, connecting platform, threaded groove, threaded adjustment rod and positioning clamp to achieve stable sliding clamping of the template and avoid friction and vibration.
The template does not rub against the connecting platform when clamped and fixed, ensuring stable sliding and improving the stability and effectiveness of the connection.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of modular bridge template quick connection device, specifically a modular bridge template quick connection device. Background Technology
[0002] As is well known, in the current process of road and bridge construction, some structures are prefabricated, requiring improved formwork connection and support. Existing formwork is typically a single, integrated structure, necessitating multiple sets of formwork for different prefabricated structures, with the overall structure fixed. Current bridge formwork connection methods rely on welding, which is inconvenient for overall assembly, disassembly, and adjustment, hindering recycling and subsequent standardized management. There is a lack of methods for combining and connecting formwork or for rapid formwork installation and connection.
[0003] A modular bridge formwork quick connection device with application number CN202321839906.3 can effectively fix the bridge formwork and prevent it from falling off. However, when the clamping plates hold and fix the formwork, the formwork itself will generate a large friction force with the connecting platform due to its own weight, causing the connecting platform to vibrate, thus affecting the fixing effect of the formwork. Therefore, we propose a modular bridge formwork quick connection device to solve the above problems. Utility Model Content

[0019] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 This utility model discloses a modular bridge template quick connection device, comprising a sliding adjustment base 1, a telescopic column 2 on the top of the sliding adjustment base 1, a bidirectional threaded rod 3 inside the sliding adjustment base 1, and several spherical arc grooves 4 on the top of the sliding adjustment base 1. Each spherical arc groove 4 has a spherical slider 5 in its center, and each spherical slider 5 engages with the spherical arc groove 4 in a sliding engagement manner, allowing the spherical slider 5 to slide along the spherical arc groove 4. Each bidirectional threaded rod 3 has a connecting platform 6 on its top, and each connecting platform 6 has several threaded grooves 7. Each threaded groove 7 has a threaded adjusting rod 8 in its center, and each threaded adjusting rod 8 has an adjusting handle, allowing the threaded adjustment of the modular bridge template quick connection device to be adjusted. The section rod 8 is easy to adjust manually. Each threaded adjusting rod 8 cooperates with the threaded groove 7. The cooperation between each threaded adjusting rod 8 and the threaded groove 7 is a threaded fit, so that the threaded adjusting rod 8 can be adjusted along the threaded groove 7. Each threaded adjusting rod 8 is equipped with a positioning clamp 9. The edges of the sliding adjusting base 1, telescopic column 2, bidirectional threaded rod 3, spherical arc groove 4, spherical slider 5, connecting platform 6, threaded groove 7, threaded adjusting rod 8 and positioning clamp 9 are all rounded, so that the modular bridge template quick connection device will not scratch the user during use. When the clamping plate clamps and fixes the template, the template will not rub against the connecting platform 6. It can slide stably along the connecting platform 6 under the adjustment of the positioning clamp 9, thereby achieving clamping and positioning without causing vibration of the template connecting platform 6.
[0021] In summary, this modular bridge template quick connection device, when in use, first moves the sliding adjustment base 1 to a suitable position, then adjusts the telescopic column 2, places the bridge template on the connecting platform 6, and uses the cooperation between each threaded adjustment rod 8 and the threaded groove 7 to clamp and position the bridge template with several positioning clamps 9. During the adjustment process, several spherical sliders 5 can slide along the spherical arc groove 4, thus preventing the template from generating significant friction with the connecting platform 6. Then, adjust the bidirectional threaded rod 3, and use the threaded cooperation to adjust the position of the two telescopic columns 2 to position the template. When the clamping plates clamp and fix the template, the template will not rub against the connecting platform 6 and can slide stably along the connecting platform 6 under the adjustment of the positioning clamps 9, thereby achieving clamping and positioning without causing vibration of the connecting platform 6. This modular bridge template quick connection device has a better performance.
