[0036] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0037] See Figure 1-8A reusable simple support device for bridge piers includes a pier column 7. Multiple pairs of conical nuts 3 are fixed internally on both sides of the pier column 7. A hanging structure 1 is fixedly installed on the conical nuts 3 via high-strength bolt assemblies 2. A relief block 4 is supported on the top of the hanging structure 1, and a truss plate structure 5 is supported on the top of the relief block 4. The truss plate structures 5 located on both sides of the pier column 7 are fixedly connected by tie bolt assemblies 6. Inclined support frames 9 are fixed to both ends of the top of the truss plate structures 5. A template 10 is laid on top of the inclined support frames 9 and the truss plate structures 5. Its steel structure support members are connected and fixed to the bridge pier column via high-strength bolt assemblies, eliminating the need for aerial welding. Installation and dismantling are convenient, and the support structure, including the embedded parts, can be reused for the next bridge pier after removal. It is unaffected by the site environment and is not limited by the height of the pier column.

[0038] Furthermore, the tapered nut 3 is pre-embedded during the casting process of the pier column 7. The use of the pre-embedded tapered nut 3 ensures the reliable fixing and installation of the high-strength bolt assembly 2 in the future.

[0039] Furthermore, the bolt assembly 2 includes a high-strength bolt 201, which is fixedly connected to a tapered nut 3. A nut 202 for fixing the bracket structure 1 is installed at the end of the high-strength bolt 201. The bolt assembly 2 enables reliable fixing of the bracket structure 1. In the specific installation process, the high-strength bolt 201 is first fixedly connected to the pre-embedded tapered nut 3, and then the bracket structure 1 is locked and fixed to the high-strength bolt 201 using the nut 202.

[0040] Furthermore, the mounting structure 1 includes a mounting plate 101 with multiple through holes 102 for the bolt assembly 2 to pass through. Parallel hanging beams 103 are fixed to the outer wall of the mounting plate 101, and a reinforcing plate 104 is fixed between the bottom end of the hanging beams 103 and the mounting plate 101. This mounting structure 1 effectively secures the unloading block 4 on its top. Moreover, the mounting structure 1 ensures the reliability and stability of the support for the entire device.

[0041] Furthermore, the truss panel structure 5 includes a truss bottom beam 501, the top of which is supported by a truss top beam 504 via a truss column 502. A connecting plate 505 is fixed between the truss column 502 and the truss bottom beam 501. Bolt through holes 503 for passing through the tie bolt assembly 6 are machined on the truss bottom beam 501 and the truss top beam 504. This truss panel structure 5 facilitates reliable support for the inclined support frame 9 and template at its top, thereby ensuring its structural strength and stability.

[0042] Furthermore, the tie bolt assembly 6 includes a double-ended threaded rod 601, with locking nuts 602 installed at both ends of the double-ended threaded rod 601. The tie bolt assembly 6 allows for reliable assembly and connection of the truss plate structures 5 on both sides, thereby connecting them into a whole to ensure structural strength and stability.

[0043] Furthermore, the slope of the inclined support frame 9 is the same as the slope of both ends of the cap beam 8 to be cast. The inclined support frame 9 described above can be used to cast and shape the sloping bottom of the cap beam 8.

[0044] Furthermore, the inclined support frame 9 includes a support base beam 901, and the top of the support base beam 901 is fixedly supported by a top inclined beam 903 through multiple short columns 902 of different lengths. The inclined support frame 9 ensures its structural strength and stability, thereby guaranteeing the quality of subsequent pouring.

[0045] The working process and principle of this utility model:

[0046] During the specific construction process, conical nuts 3 are first pre-embedded during the construction of pier 7. After the pier 7 is completed, the factory-processed hanging structure 1 is connected and fixed to the pre-embedded conical nuts 3 using high-strength bolt assemblies 2. A relief block 4 is placed on the top surface of the hanging structure 1. Then, the processed truss structure 5 is lifted and placed on the relief block 4. To increase the overall stability of the truss structure 5, the two truss structures 5 are pulled together by tie rods 6. An inclined support frame 9 with the same slope is placed on the inclined bottom plate of the cap beam. A template 10 is laid on the truss structure 5 and the inclined support frame 9 to form the support frame of the cap beam. After the cap beam 8 is completed, all members are removed from top to bottom. Finally, the high-strength bolt assembly 2 is loosened, the hanging structure 1 is removed, and the conical nuts 3 are screwed out of the pier, achieving the goal that all support members of the cap beam, including the pre-embedded parts, can be reused.
