Technical Field

[0001] The utility model relates to the technical field of bridge pile foundations, in particular to a positioning device for a bridge pile foundation reinforcement cage. Background Art

[0002] The bridge foundation is the lowest part of the bridge that is in direct contact with the ground. It is used to bear all loads transmitted from the superstructure to ensure the normal use and safety of the bridge.

[0003] Bridge pile foundations usually adopt reinforced concrete structures. During the construction of bridge pile foundations, in order to improve the welding effect between the steel cages, a positioning device is usually used to limit the positioning of the steel cages, thereby avoiding offset between the upper and lower steel cages.

[0004] Most of the existing positioning devices are integral structures. When positioning the steel cage, due to the large size of the steel cage, the size and weight of the positioning device are also large, making it inconvenient to carry the positioning device. When transporting the positioning device, it often consumes a lot of manpower and material resources, which in turn affects the construction efficiency of the bridge pile foundation. Utility Model Content

After completing the assembly and connection of the four frame plates, the assembly side plates of the two adjacent frame plates are fitted together, and then by connecting the adjacent assembly side plates, the stability of the assembly connection of the adjacent frame plates can be improved. By setting a stable bottom plate, the stability of the frame plates after assembly and connection can be improved.

By setting a stable bottom plate, the stability of the frame plates after assembly and connection is improved. When the extruded outer plate approaches the steel cage body under the joint action of the threaded rod and the limit rod, until the extruded outer plate is tightly fitted with the steel cage body, the extruded outer plate is set to be used in conjunction with the sliding layer plate, and the double fitting and clamping of the steel cage body is achieved by the extruded outer plate and the sliding layer plate.

[0012] As a further improvement of the above technical solution: a threaded hole is opened on the inner side of the assembly side plate, and the height of the assembly side plate is the same as the height of the frame plate.

[0013] The beneficial effect of this improvement is that after the assembly and connection of the four frame panels are completed, the assembly side panels of two adjacent frame panels are fitted together, and then by connecting the adjacent assembly side panels, the stability of the assembly connection of the adjacent frame panels can be improved, and by setting a stable bottom plate, the stability of the frame panels after assembly and connection can be improved.

[0014] To connect the U-shaped frame to two adjacent assembly side panels:

[0015] As a further improvement of the above technical solution: the height of the U-shaped frame is the same as the height of the assembled side panel, the inner wall of the U-shaped frame is connected with a wear-resistant inner layer, the wear-resistant inner layer is a rubber layer with a U-shaped cross-section when viewed from above, and a threaded hole is opened on the inner side of the U-shaped frame.

[0016] The beneficial effect of this improvement is: the U-shaped frame is connected to the two adjacent assembly side panels at the same time, and the bottom of the positioning triangle bottom plate and the bottom of the stable bottom plate are located at the same horizontal plane, and then the U-shaped frame is connected to the two adjacent assembly side panels at the same time using bolts.

[0017] In order to squeeze the outer plate, it moves linearly under the joint action of the threaded rod and the limit rod:

[0021] As a further improvement of the above technical solution: the positioning outer plate is connected to the outer wall of the frame plate, and the top view cross section of the extruded outer plate is an arc-shaped structure.

[0022] The beneficial effect of this improvement is that when the extruded outer plate approaches the steel cage body under the joint action of the threaded rod and the limit rod, until the extruded outer plate and the steel cage body are tightly fitted, the extruded outer plate is used in conjunction with the sliding layer plate, and the double fitting and clamping of the steel cage body is achieved through the extruded outer plate and the sliding layer plate.

[0023] In order to improve the fixing effect of the steel cage body by sliding the layer plate:

[0024] As a further improvement of the above technical solution: one end of the compression spring away from the sliding layer is connected to the inner wall of the sliding groove.

[0025] The beneficial effect of this improvement is that by setting the compression spring, pressure can be applied to the sliding layer through the elastic force of the compression spring, thereby improving the fixing effect of the steel cage body through the sliding layer, facilitating the subsequent construction of the bridge pile foundation.

[0026] In order to ensure the clamping force of the sliding layer on the main body of the steel cage:

[0027] As a further improvement of the above technical solution: the cross-section of the sliding layer plate in a top view is arranged as an arc-shaped structure, and an end of the sliding layer plate away from the compression spring is connected with an anti-slip layer.

[0028] The beneficial effect of this improvement is that when the anti-skid layer is tightly fitted with the steel cage body through the sliding layer plate under the elastic force of the compression spring, the anti-skid layer can increase the friction between it and the steel cage body, thereby ensuring the clamping force of the sliding layer plate on the steel cage body.
