A clamping piece is provided on the fixture body, and the steel arch frame is clamped by the clamping part of the clamping piece, which can limit the spacing between the steel arch frames, save labor costs, and install the steel arch frames efficiently and accurately.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] like Figures 1 to 4 As shown, the present invention provides a steel arch positioning fixture, comprising a fixture body 1 and a clamping member 2. The fixture body 1 is used to position and support the clamping member 2. The fixture body 1 can be in the form of a plate or rod. The fixture body 1 is provided with a first connecting structure, which can be in the form of a hole, groove, or ring. The clamping member 2 is provided with a second connecting structure and a clamping portion, which can also be in the form of a hole, groove, or ring. The second connecting structure and the first connecting structure can be connected by a locking structure 4. Depending on the form of the first and second connecting structures, the locking structure 4 can adopt different structures, such as screws or bolts. The clamping portion is used to clamp the steel arch. The clamping portion can be an arch, an arc, or a groove structure with a similar shape to match the contour of the steel arch and better clamp and limit the steel arch. The clamping portions are arranged on the same side of the fixture body 1, and there is a spacing between the clamping portions, so that after the clamping portions clamp the steel arch, the position of the steel arch can be accurately defined.

[0030] The utility model provides a clamping piece 2 on the clamp body 1, and utilizes the clamping portion of the clamping piece 2 to clamp the steel arch frame, which can limit the spacing between the steel arch frames. It can not only significantly improve the installation efficiency, shorten the construction period, and reduce labor costs, but also ensure the precise control of the spacing between adjacent steel arch frames and the verticality of the steel arch frames, thereby effectively ensuring the construction quality and the long-term stability of the tunnel structure.

[0031] In one embodiment, the clamp body 1 is a first rectangular plate, which is a long strip plate with clamping parts 2 provided at both ends of its length direction. The long strip plate can be reasonably set according to the spacing of the steel arch frame to be positioned to adapt to a wider range and improve the versatility of the steel arch frame positioning clamp.

[0032] In one embodiment, the first connecting structure is a first strip hole 11 opened on the first rectangular plate, and the length direction of the first strip hole 11 is set along the length direction of the first rectangular plate to facilitate adjusting the position of the clip 2 on the first rectangular plate, and then adjusting the spacing between the clips 2.

[0033] In one embodiment, the clamping member 2 is an L-shaped plate, which includes a first arm 21 and a second arm 22 connected to each other in an L shape. The first arm 21 is connected to the clamp body 1, and the second arm 22 serves as a clamping part. At this time, the second arm 22 is used to clamp the steel arch frame.

[0034] In one embodiment, the first arm 21 is a second rectangular plate that can be fitted and connected to the first rectangular plate. The second arm 22 is a curved plate with openings facing each other so that the steel arch can be clamped to the inner side of the curved plate, ensuring that the fixture body 1 does not move during construction. The opening of the curved plate should be adapted to the size of the steel arch and match the specifications of the steel arch to ensure a close fit and achieve precise positioning.

[0035] In one embodiment, the second connecting structure is a second strip-shaped hole formed in the second rectangular plate. The second strip-shaped hole is arranged in the same direction as the first strip-shaped hole 11, which can further increase the adjustment range of the clamping member 2 on the clamp body 1. By adjusting the size and angle of the clamp body 1 and the clamping member 2 or using replaceable accessories, the clamp body 1 and the clamping member 2 can be adapted to steel arches of different specifications and shapes.

[0036] In one embodiment, the locking mechanism 4 utilizes a bolt, which cooperates with a nut to achieve locking. The bolt passes through the first and second strip holes 11 and is secured by the nut. By tightening the nut, the spacing between the first and second strip holes 11 is adjusted, securely connecting the fixture body 1 to the steel arch. Disassembly is accomplished by simply loosening the nut. This simple bolt connection allows operators to quickly position and secure the steel arch, improving construction efficiency.

[0037] In one embodiment, the second connection structure is a circular hole opened on the second rectangular plate.

[0038] In one embodiment, the locking mechanism 4 utilizes a bolt, which cooperates with a nut to achieve locking. The bolt passes through the first strip-shaped hole 11 and the circular hole and is secured by the nut. By tightening the nut, the spacing between the first strip-shaped hole 11 and the circular hole is adjusted, securely connecting the fixture body 1 to the steel arch. Disassembly is accomplished by simply loosening the nut. This simple bolt connection allows operators to quickly position and secure the steel arch, improving construction efficiency.

[0039] In one embodiment, a handle 3 is further included. The handle 3 is connected to a side of the clamp body 1 away from the clamping member 2 to facilitate the movement and positioning of the clamp body 1 .

[0040] In one embodiment, the steel arch positioning fixture is constructed from high-strength, high-hardness materials to withstand the weight of the steel arch and various external forces during construction. For example, high-quality alloy steel or high-strength engineering plastics are used to ensure long-term deformation and damage. Corrosion resistance is also a consideration, ensuring compatibility with humid and corrosive environments to extend its service life. For example, special anti-corrosion coatings or corrosion-resistant alloys can be used.

[0041] In one embodiment, when using a steel arch positioning fixture, the clamping members 2 at each end of the fixture body 1 are respectively clamped onto two adjacent steel arches. Then, based on design requirements, the distance between the clamping members 2 is adjusted to achieve the specified spacing. Finally, the clamp body 1 is securely fixed to the steel arch using the locking mechanism 4, and subsequent construction operations can proceed.
