Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction technology, and in particular to a fastening device for road and bridge construction templates. Background Technology

[0002] In road and bridge construction, the installation and securing of formwork is a crucial step. Traditional formwork fastening methods typically require a large number of bolts, clamps, or other tools, making the process extremely cumbersome. From tightening the bolts to installing each clamp individually, each step demands significant time and effort from construction workers, severely impacting construction progress. Furthermore, during disassembly, the numerous components are prone to loss or damage, rendering existing fastening devices unusable after disassembly, resulting in substantial material waste and significantly increasing construction costs.

[0003] Furthermore, with the diversification of road and bridge engineering, the demand for formwork specifications is becoming increasingly diverse. However, traditional fastening devices have poor adaptability and cannot meet the needs of various construction scenarios. In the construction of some irregularly shaped road and bridge structures, traditional fastening devices cannot be flexibly adjusted, leading to inaccurate formwork installation and affecting project quality. At the same time, in projects with tight schedules, the inefficiency of traditional fastening methods will further compress construction time and increase construction risks.

[0004] Therefore, there is an urgent need for a template fastening device that is easy to install and disassemble, reusable, and highly adaptable, in order to improve construction efficiency, reduce costs, and promote the further development of road and bridge construction technology.

[0027] like Figure 1 As shown, the stability of formwork is crucial during road and bridge construction. A formwork fastening device for road and bridge construction includes a first formwork body 1 and a second formwork body 2. A first connecting column 3 is fixedly installed at one end of both the first formwork body 1 and the second formwork body 2, and a second connecting column 4 is fixedly installed at the other end of both the first formwork body 1 and the second formwork body 2. The first connecting column 3 and the second connecting column 4 are connected to the formwork body by high-strength welding or bolt connection to ensure the stability of the connection.

[0028] The first connecting column 3 and the second connecting column 4 are fixedly connected by a first clamping mechanism and a second clamping mechanism arranged opposite to each other. This provides strong clamping force, tightly securing the connecting columns together and preventing displacement or loosening of the formwork during construction. Furthermore, a support mechanism is provided between the first and second clamping mechanisms, effectively distributing the pressure on the formwork and further enhancing the stability of the entire formwork structure, ensuring the smooth progress and quality of road and bridge construction.

[0029] Clamping components:

[0030] The first clamping mechanism includes an integrally formed first inclined top block 5 and a first vertical plate 6 perpendicular to the first inclined top block 5. The first inclined top block 5 is cast from a high-strength alloy material, with a smooth surface and extremely high precision, providing uniform and stable pressure during the clamping process. The first vertical plate 6 can be pre-set with multiple precisely positioned mounting holes for connection and fixation with other components.

[0031] The second clamping mechanism includes a second inclined top block and a second vertical plate 7. The structure of the second inclined top block is compatible with that of the first inclined top block 5. It is also made of high-quality materials and has good wear resistance and deformation resistance. The first inclined top block 5 and the second inclined top block are interlocked. During the interlocking process, the two fit tightly together to achieve a seamless connection. This ensures that pressure is evenly transmitted when the formwork is tightened, effectively preventing deformation or damage caused by uneven local stress on the formwork, and providing a solid guarantee for the stability of the formwork in road and bridge construction.

[0032] The second inclined plate includes a first inclined plate 8 and a second inclined plate 9, which are identical in structure and arranged in parallel. The first inclined plate 8 and the second inclined plate 9 are forged from high-strength alloy steel and precision CNC machined to ensure that the surface flatness error is controlled within ±0.05mm and the parallelism error does not exceed ±0.03mm. The sides of the first inclined plate 5, the first inclined plate 8, and the second inclined plate 9 closest to the first template body 1 and the second template body 2 are all flat. These flat surfaces are hardened by quenching, achieving a hardness of HRC58-62, effectively resisting wear and extrusion deformation of the template surface. The sides of the first inclined plate 5, the first inclined plate 8, and the second inclined plate 9 furthest from the first template body 1 and the second template body 2 are all inclined surfaces. The inclination angle of the inclined surfaces is 60°±1°, which allows the fastening force to be evenly distributed along the axial direction, avoiding stress concentration.

[0033] One end of the first inclined plate 8 and the second inclined plate 9 is integrally formed with a connecting block 10 through a die forging process. The connecting block 10 is fixedly connected to the second vertical plate 7. Both the second vertical plate 7 and the connecting block 10 have insertion holes 11 corresponding to the first inclined top block 5. The structure of the insertion hole 11 is adapted to the first inclined top block 5 to ensure smooth insertion and positioning accuracy of the first inclined top block 5. To further enhance the connection reliability, a copper alloy bushing is embedded in the insertion hole 11, which can reduce metal-to-metal friction and provide good corrosion resistance. When the first inclined top block 5 is fully inserted into the insertion hole 11, the fit gap between the two is only 0.08-0.12mm. Through this precise fit, the lateral force during the fastening process can be effectively converted into axial clamping force, thereby improving the template fastening effect.

[0034] A locking screw 12 is horizontally installed between the first upright plate 6 and the second upright plate 7. One end of the locking screw 12 is fixedly connected to the second upright plate 7, and the other end of the locking screw 12 passes through the first upright plate 6 and is screwed to a locking handle 13. The through end of the locking screw 12 is provided with an external thread, and the locking handle 13 is provided with a locking nut 22 that mates with the external thread to ensure smooth engagement and sufficient preload. By rotating the locking handle 13, the distance between the first upright plate 6 and the second upright plate 7 can be adjusted, thereby clamping the template.

[0035] The support mechanism includes a support screw 14, a support plate 15, a first slide rod 16, and a second slide rod 17. The axes of the first slide rod 16 and the second slide rod 17 are collinear. One end of the first slide rod 16 is fixedly connected to the first upright plate 6, and one end of the second slide rod 17 is fixedly connected to the second upright plate 7. The other end of the first slide rod 16 is slidably connected to the other end of the second slide rod 17 via a sliding sleeve 18. The upper surfaces of both the first slide rod 16 and the second slide rod 17 are provided with sliders, and the inner wall of the sliding sleeve 18 is provided with grooves corresponding to the sliders.

[0036] A support plate 15 is fixedly mounted on the front end of the sliding sleeve 18. A spearhead 19 is connected to the bottom end of the support screw 14, which passes through the support plate 15. The spearhead 19 can penetrate the ground for securing the entire device. A horizontally positioned support baffle 21 is fitted onto the through end of the support screw 14. A screw hole is provided on the support plate 15 to mate with the support screw 14. A handwheel 20 is fixedly mounted on the top end of the support screw 14. Rotating the handwheel 20 adjusts the height of the support screw 14 to achieve its supporting function.

[0037] When this device is used in road and bridge construction:

[0038] First, place the first template body 1 and the second template body 2 according to the construction requirements, so that the first connecting column 3 and the second connecting column 4 of the two are aligned. Insert the first inclined top block 5 of the first clamping mechanism into the insertion hole 11 of the first inclined plate 8, the second inclined plate 9 and the connecting block 10 of the second clamping mechanism, so that the first vertical plate 6 and the second vertical plate 7 are opposite each other; then rotate the locking handle 13 and adjust the distance between the two vertical plates by the locking screw 12 until the template is clamped.

[0039] During the clamping process, the sliding sleeve 18 slides on the first sliding rod 16 and the second sliding rod 17 to make the support plate 15 properly positioned; then the support mechanism is adjusted by turning the handwheel 20 to adjust the height of the support screw 14. The support baffle 21 is set horizontally to maintain balance. As the handwheel 20 rotates, the support screw 14 drives the spearhead 19 to pierce the ground for fixation, completing the installation of the template fastening device, and subsequent construction can proceed.

[0040] Therefore, this utility model adopts the above-mentioned fastening device for road and bridge construction templates. Through the design of clamping and supporting structure, it can achieve stable installation of templates, is easy and efficient to operate, is applicable to a variety of templates and can be reused, and significantly reduces construction costs and time.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
