As those skilled in the art will appreciate, the described embodiments can be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] Compared with the prior art of sticking ordinary rubber pads on the inner wall of the clamp, in the present embodiment, an attachment platform 2 and a hydraulic support mechanism 4 are additionally provided on the clamp body 1. When the clamp body 1 is fixed on the pier column 9 by the fixing mechanism 3, the hydraulic support mechanism 4 can be manually controlled to make its movable end squeeze and contact with the pier column 9 in the form of hydraulic additional force and generate friction, and the support angle of the hydraulic support mechanism 4 can be flexibly adjusted to prevent the clamp body 1 from slipping off the pier column 9, thereby reducing construction risks.
[0029] Furthermore, the hydraulic support mechanism 4 includes: a rotating ring 41, an operating handle 42, a handle bracket 43, a hydraulic component 44 and a support component 45; the rotating ring 41 is movably arranged on the attachment platform 2; the handle bracket 43 is arranged on the rotating ring 41; one end of the hydraulic component 44 is connected to the handle bracket 43, and the other end of the hydraulic component 44 is connected to the support component 45; one end of the operating handle 42 is movably arranged on the handle bracket 43, and the other end of the operating handle 42 is connected to the hydraulic component 44.
[0030] In this embodiment, the rotating ring 41 is rotatably arranged on the attachment platform 2, the handle bracket 43 is installed on the rotating ring 41, the operating handle 42 is movably arranged on the handle bracket 43, and is connected to the hydraulic component 44, and the two ends of the hydraulic component 44 are respectively connected to the handle bracket 43 and the support component 45 (see Figure 4 ), the operating handle 42 can drive the hydraulic component 44 to move, so that the support component 45 on the movable end of the hydraulic component 44 is pressed against the pier 9, and the support component 45 is squeezed and contacted with the pier 9 under the action of the hydraulic component 44 and generates friction, thereby increasing the friction between the clamp body 1 and the pier 9.
[0031] Furthermore, the hydraulic assembly 44 includes: a hydraulic pump cylinder 51, a hydraulic telescopic rod 52 and an oil return valve 53; one end of the hydraulic pump cylinder 51 is arranged on the handle bracket 43, and the other end of the hydraulic pump cylinder 51 is connected to the hydraulic telescopic rod 52; one end of the hydraulic telescopic rod 52 is connected to the rotating ring 41, and the other end of the hydraulic telescopic rod 52 is connected to the support assembly 45; the oil return valve 53 is arranged on the hydraulic telescopic rod 52.

The two ends of the hydraulic telescopic rod 52 are respectively connected to the rotating ring 41 and the supporting assembly 45, and the oil return valve 53 is arranged on the hydraulic telescopic rod 52.
[0033] The working principle of the hydraulic assembly 44 is the same as that of the hydraulic jack. Based on the principle of hydraulic transmission, when the handle bracket 43 moves, the hydraulic pump cylinder 51 can be shaken up and down to squeeze the hydraulic oil, so that the hydraulic telescopic rod 52 is extended under the action of the hydraulic oil force, thereby achieving the tightening effect of the support assembly 45; when disassembly is required, the oil return valve 53 is rotated to reduce the pressure of the hydraulic oil, thereby shortening the hydraulic telescopic rod 52, thereby achieving the loosening effect of the support assembly 45.
[0034] Furthermore, the support assembly 45 includes: a limiting steel plate 61, a friction plate 62 and a plurality of limiting steel bars 63; the limiting steel plate 61 is movably connected to the hydraulic telescopic rod 52; the friction plate 62 is arranged on the limiting steel plate 61; a plurality of limiting steel bars 63 are circumferentially arranged on the limiting steel plate 61, and the limiting steel bars 63 are connected to the friction plate 62.

Under the tightening action of the hydraulic assembly 44, the friction plate 62 is squeezed into contact with the pier 9 and generates friction, thereby increasing the friction between the clamp body 1 and the pier 9.
[0036] Furthermore, a rotating ball joint 71 is provided at the movable connection between the limiting steel plate 61 and the hydraulic telescopic rod 52 .
[0037] In this embodiment, the rotating ball joint 71 is arranged at the connection between the limiting steel plate 61 and the hydraulic telescopic rod 52. The rotating angle of the limiting steel plate 61 can be adjusted by rotating the ball joint 71, so that the friction plate 62 can have a better angle of friction contact with the pier 9.
[0038] Furthermore, a plurality of fixing screws 72 are provided at the connection between the friction plate 62 and the limiting steel plate 61 .
[0039] In this embodiment, the fixing screws 72 are respectively connected to the limiting steel plate 61 and the friction plate 62 , which can make the connection between the limiting steel plate 61 and the friction plate 62 more stable.

[0041] In this embodiment, the oblique stiffening steel plate 22 is a right-angled triangular steel plate, and two oblique stiffening steel plates 22 are provided. The horizontal attachment steel plate 21 is installed at the upper end of the oblique stiffening steel plate 22 (see Figure 4 ), the hydraulic support mechanism 4 is arranged on the horizontal attachment steel plate 21, and a stable triangular mechanism is formed between the above structures, thereby increasing the structural stability of the attachment platform 2.
[0042] Furthermore, a square avoidance groove 8 is formed on the horizontal attachment steel plate 21 ; and the rotating ring 41 is movably disposed in the square avoidance groove 8 .
[0043] In this embodiment, a square air avoidance groove 8 is hollowed out on the horizontally attached steel plate 21, and the square air avoidance groove 8 is located between the two oblique stiffening steel plates 22. The rotating ring 41 is rotatably set at one side of the square air avoidance groove 8, so that the hydraulic support mechanism 4 structure can pass through the square air avoidance groove 8, which is convenient for manual operation by construction personnel.
[0044] Furthermore, the fixing mechanism 3 includes: a clamp fixing piece 31 and a plurality of fixing bolts 32 ; the clamp fixing piece 31 is arranged on the clamp body 1 ; and the fixing bolts 32 are detachably arranged on the clamp fixing piece 31 .
[0045] In this embodiment, since the clamp body 1 is a two-part structure that can be separated from each other, a clamp fixing member 31 is provided on both sides of the clamp body 1 (see Figure 2 ), the fixing bolts 32 are respectively connected to the clamp fixing members 31 at both sides, and the multiple fixing bolts 32 can connect and lock the clamp fixing members 31 at both sides, so that the clamp body 1 can be fixed on the pier 9 through the locking effect of the clamp fixing members 31.
