Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the concrete used in the bridge abutment will cause unexpected deformation of the pre-embedded steel bars, which makes it very difficult to install the bridge support in the later stage. The purpose is to provide equipment that facilitates the installation of the bridge support and solve the above problems

Embodiment 1

[0039] Such as figure 1 , figure 2 and image 3 As shown, the present invention facilitates the installation of bridge supports, including a frame 1, a longitudinal clamp bar 2, a transverse clamp bar 3 and a sleeve 4; the longitudinal clamp bar 2 and the transverse clamp bar 3 are movably arranged inside the frame 1, and The angle between the longitudinal clamping bar 2 and the transverse clamping bar 3 is 90°; the intersecting longitudinal clamping bar 2 and the transverse clamping bar 3 are movably connected through the sleeve 4; The cylinder 4 moves longitudinally along the transverse clamp rod 3 in the through hole; the outer surface of the sleeve 4 is provided with a spring ball 6 longitudinally along the transverse clamp rod 3; the longitudinal clamp rod 2 is arranged inside the sleeve 4 and along the The longitudinal clamping rod 2 moves longitudinally; the inner wall of the sleeve 4 is provided with balls longitudinally along the longitudinal clamping rod 2 .

Embodiment 2

[0043] In this embodiment, on the basis of Embodiment 1, the longitudinal clamping bar 2 and the horizontal clamping bar 3 are movably connected to the frame 1, and the longitudinal clamping bar 2 moves longitudinally along the horizontal clamping bar 3, and the horizontal clamping bar 3 moves along the longitudinal clamping bar 2. longitudinal movement.

[0044] During the implementation of this embodiment, in order to enable the longitudinal clamping bar 2 and the horizontal clamping bar 3 to better complete the clamping of the pre-embedded steel bars, the present invention limits the moving direction of the longitudinal clamping bar 2 and the horizontal clamping bar 3 .

Embodiment 3

[0046] Such as figure 1 As shown, on the basis of Embodiment 1, this embodiment further includes a transmission device 5; the transmission device 5 is connected to the longitudinal clamping rod 2 and the lateral clamping rod 3 through a screw.

[0047] When this embodiment is implemented, the pre-embedded steel tends to bear a relatively large stress. When the longitudinal clamping bar 2 and the horizontal clamping bar 3 are adjusted completely by manpower, it is easy to have a large error. Therefore, the present invention uses the transmission device 5 to amplify the power or Adding external power to the transmission device can effectively improve the use effect of the present invention.

Abstract

The invention discloses equipment convenient for mounting a bridge support. A longitudinal clamping bar and a horizontal clamping bar are movably arranged inside a frame, and an included angle betweenthe longitudinal clamping bar and the horizontal clamping bar is 90 degrees; the intersected longitudinal clamping bar and horizontal clamping bar are movably connected by virtue of a sleeve; a through hole which is transversely cut-through is formed in the horizontal clamping bar, and the sleeve longitudinally moves along the horizontal clamping bar in the through hole; spring balls are longitudinally arranged along the horizontal clamping bar on the outer surface of the sleeve; the longitudinal clamping bar is arranged inside the sleeve, and the sleeve longitudinally moves along the longitudinal clamping bar; and balls are arranged along the longitudinal direction of the longitudinal clamping bar on the inner wall of the sleeve. The equipment convenient for mounting the bridge support has the advantages that an embedded reinforcement is effectively limited from an embedding process to a moment before mounting by virtue of structural design of the sleeve, the longitudinal clamping bar and the horizontal clamping bar, when the bridge support is mounted, a mounting process is more convenient, working procedures are reduced, operation time is shortened, and construction safety is effectively improved.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to equipment for facilitating the installation of bridge supports. Background technique [0002] Bridge bearings are important structural components connecting the bridge superstructure and substructure. It can reliably transmit the reaction force and deformation (displacement and rotation angle) of the bridge superstructure to the bridge substructure, so that the actual stress of the structure is consistent with the calculated theoretical diagram. The bridge support is erected on the pier, and the top surface supports the device of the bridge superstructure. Its function is to fix the superstructure to the abutment, withstand various forces acting on the superstructure, and transmit it reliably to the abutment; under the action of load, temperature, concrete shrinkage and creep, the support can adapt to the superstructure The rotation angle and displacement allow the upper struc...
