[0030] like Figure 1 and Figure 3 As shown, in this embodiment, the distribution beams 5 are multiple beams arranged in parallel at intervals, and these multiple distribution beams 5 are vertically installed on the load-bearing beam 4. By setting multiple distribution beams, the support effect is good, and it is also convenient to set up the construction platform 9. The construction platform 9 is equipped with a protective net.
[0031] like Figures 1-4 As shown, in this embodiment, the two sets of first bracket supports 11 of the upper clamp 1 and the two sets of second bracket supports 21 of the lower clamp 2 are arranged in a one-to-one correspondence. Each set of second bracket supports 21 of the lower clamp 2 is provided with a support beam 3 on both sides. By arranging the first bracket supports and the second bracket supports in a corresponding manner, it is convenient to set up the support beams.
[0032] Specifically, the two sets of first bracket supports 11 of the upper clamp 1 are fastened together by first fasteners 12. The two sets of second bracket supports 21 of the lower clamp 2 are fastened together by second fasteners 22. The first fasteners 12 and the second fasteners 22 can be connecting components that use nuts and bolts.
[0033] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the support beam 3 is arranged vertically, the upper end of the support beam 3 is welded and fixed to the lower surface of the upper clamp 1, and the lower end of the support beam 3 is welded and fixed to the upper surface of the lower clamp 2.

[0038] In this embodiment, the support beam 3, load-bearing beam 4, and distribution beam 5 can all be made of I-beams.
[0039] This embodiment of a bridge cap beam support device provides support for formwork installation and concrete pouring during cap beam construction, while also providing a working platform for construction workers to ensure the smooth progress of cap beam construction. This embodiment utilizes a double-clamp structure to support the entire weight of the cap beam during construction, ensuring a reliable load-bearing system and platform for high-altitude operations. Furthermore, the installation and dismantling methods are relatively simple, with low investment costs, and ensure the safety of construction workers.
[0040] This embodiment also provides a construction method for the above-mentioned bridge cap beam support device, including the following steps:
[0041] S1, the first bracket 11 of the upper clamp 1 is pre-assembled using the first fastener 12, and the second bracket 21 of the lower clamp 2 is pre-assembled using the second fastener 22;
[0042] Specifically, tighten the nut until the outer edge of the nut is flush with the screw.
[0043] S2, lift the lower clamp 2, manually assist in positioning, after accurate positioning, install the lower clamp 2 on the pier 6, and tighten the lower clamp 2 to make the lower clamp 2 and the pier 6 fit tightly together;
[0044] Apply pre-tension to each high-strength bolt using a torque wrench. Tighten each bolt to a similar degree, ensuring uniform force on each bolt and achieving the designed tensile strength. This guarantees sufficient and uniform friction between the clamp and the pier. Observe the mating surfaces of the clamp and pier to ensure a tight fit. Also, check the condition of the clamp's surfaces and welds for deformation or cracks. After installation, use a digital torque wrench to test the bolt torque; retighten any bolts that do not meet requirements.
[0045] S3, After the lower clamp 2 is installed, install the jack 10 on the upper surface of the second bracket 21 of the lower clamp 2;
[0046] S4. Install the upper clamp 1 according to the method of installing the lower clamp 2. After the upper clamp 1 is installed, re-measure the top elevation of the upper clamp 1. Use jack 10 to adjust the error. After there is no error, set support beams 3 on both sides of jack 10. Weld the upper and lower ends of the support beams 3 to the upper clamp 1 and the lower clamp 2 respectively. Then unload the jack 10.
[0047] S5. After the double clamps are installed, the load-bearing beam 4 is erected on the first bracket 11 of the upper clamp 1. Then, the distribution beam 5 is installed on the load-bearing beam 4. The construction platform 9 is erected on the distribution beam 5. The protective net (dense mesh net) can be hung on the construction platform.
[0048] This embodiment applies the double-clamp method to the cap beam construction support process, which greatly improves the safety of cap beam construction while also ensuring a simple and easy-to-operate construction process. Furthermore, using this cap beam support device can effectively accelerate construction speed, reduce safety hazards, improve work efficiency, and its reusable nature can also save costs to some extent.
