Description

Technical Field

[0001] The utility model belongs to the technical field of bridges, and in particular relates to a single-column pier anti-beam torsion device. Background Art

[0002] Single-column pier bridges have been widely used in the construction of bridges such as urban overpasses and highway ramps in recent years due to their advantages of small footprint, improved low-space layout and bridge aesthetic structure.

[0003] The patent announcement number of the prior art is CN220643906U, which is a lateral anti-overturning reinforcement structure for a single-column pier bridge. The above patent includes a single-column pier, a supporting device is installed at the lower end of the single-column pier, and auxiliary supporting blocks are installed at the front end, left end, rear end and right end of the supporting device. A fixing device is installed at the upper part of the outer surface of the single-column pier, a cap beam is installed at the upper end of the single-column pier, and the cap beam is installed at the upper end of the fixing device, and reinforcement buffer devices are installed at the upper left and upper right parts of the cap beam. By adding a reinforced buffer device and adding supports to the cap beam to turn it into a three-support type, the anti-overturning moment is increased, and the problem of the single-column pier's single support having a small anti-overturning stability coefficient and easy overturning under eccentric load and heavy traffic is solved. In addition, when the vibration of the upper bridge is transmitted to the single-column pier, buffering and shock absorption are performed through a number of spring shock absorbers between the buffer seat and the connecting seat, thereby further improving the stability of the single-column pier. However, the following deficiencies still exist in actual use: From a practical point of view, the device fixes the cap beam to the single-column pier by anchor bolts, and the torsion resistance of the cap beam is weak, and torsional deviation is prone to occur. At the same time, there is a lack of buffering support for the cap beam. Under the long-term load of the cap beam on the single-column pier, the single-column pier is easily damaged.

[0004] Therefore, a single-column pier anti-twisting device for the beam body is needed to solve the problems of weak anti-twisting ability of the cap beam and lack of buffer support for the cap beam in the prior art. Utility Model Content

[0007] It should be noted in the scheme that the fixing mechanism includes two mounting plates, which are symmetrically arranged on the upper part of the single-column pier front and back, and limiting grooves are provided on the mounting plates and matched with the cap beam. The mounting plates are threaded with a first anchor bolt, and the mounting plates are installed on the single-column pier through the first anchor bolt.

A second anchor bolt is threadedly connected to the positioning plate, and the positioning plate is fixedly installed on the single-column pier through the second anchor bolt.

[0010] As a preferred embodiment, the support plate is matched with the lower surface of the cap beam and is slidably arranged on the positioning plate through a fixing block, so as to improve the stability of the cap beam and provide sufficient support for it.

[0011] As a preferred embodiment, four buffer springs are arranged in the movable groove, and the four buffer springs are arranged at the bottom of the fixed block.

[0022] The fixing mechanism 3 facilitates the position limiting of the cap beam 2 to improve its torsion resistance, while the buffer mechanism 4 facilitates the buffering support of the cap beam 2 to buffer the load received at the bottom of the single-column pier 1, thereby improving the stability of the single-column pier 1. After actual installation, the shock absorber 5 further improves the buffering effect of the cap beam 2 to reduce the actual load.

[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the fixing mechanism 3 includes two mounting plates 301, and the two mounting plates 301 are symmetrically arranged on the upper part of the single-column pier 1 front and back, and a limiting groove 302 is provided on the mounting plate 301 and matches the cap beam 2, and a first anchor bolt 303 is threadedly connected on the mounting plate 301, and the mounting plate 301 is installed on the single-column pier 1 through the first anchor bolt 303, and both sides of the mounting plate 301 protrude from the surface of the single-column pier 1 and match the buffer mechanism 4.

[0024] The cap beam 2 is torsionally limited by the limiting groove 302 to prevent it from rotating and improve its stability so as to provide stable support for the cap beam 2.

[0025] According to the above working process, it can be known that: by setting the fixing mechanism 3, when the cap beam 2 is installed on the upper part of the single-column pier 1 through the support 6, it can be torsionally limited in the horizontal direction, thereby improving its stability when installed on the upper part of the single-column pier 1.

[0026] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the buffer mechanism 4 includes two support plates 401, the two support plates 401 are symmetrically arranged at the lower part of the cap beam 2 and at both sides of the single column pier 1, the bottom of the support plate 401 is fixedly connected with a fixed block 402, the lower part of the fixed block 402 is fixedly installed with a positioning plate 403 between the two mounting plates 301, the upper part of the positioning plate 403 is provided with a movable groove 405 matching the fixed block 402, and a buffer spring is fixedly installed in the movable groove 405 at the bottom of the fixed block 402 Spring 406, the second anchor bolt 404 is threadedly connected to the positioning plate 403, the positioning plate 403 is fixedly installed on the single column pier 1 through the second anchor bolt 404, the support plate 401 is matched with the lower surface of the cap beam 2, and is slidably arranged on the positioning plate 403 through the fixing block 402, four buffer springs 406 are arranged in the movable groove 405, and the four buffer springs 406 are arranged at the bottom of the fixing block 402, and the second anchor bolt 404 is arranged at the lower part of the movable groove 405 through the positioning plate 403.

[0027] By pressing down the buffer spring 406 by the fixed block 402, the buffer spring 406 provides a certain buffer to the support plate 401, so as to provide buffer support for the cap beam 2, improve the stability of the cap beam 2 on the upper part of the single-column pier 1, and at the same time reduce its load on the single-column pier 1, thereby improving the stability of the single-column pier 1.

[0028] This solution has the following working process: when this device is used, the device is installed on the single-column pier 1 through the first anchor bolt 303 and the second anchor bolt 404. At this time, the cap beam 2 corresponding to the limit groove 302 and the support plate 401 are installed on the top of the single-column pier 1 through the support 6. At this time, the cap beam 2 is torsionally limited by the limit groove 302 to prevent it from rotating and improve its stability. At the same time, the buffer spring 406 is pressed down by the fixed block 402, so that the buffer spring 406 provides a certain buffer to the support plate 401, so as to provide buffering support for the cap beam 2, improve the stability of the cap beam 2 on the upper part of the single-column pier 1, and at the same time reduce its load on the single-column pier 1, improve the stability of the single-column pier 1, and after actual installation, the shock absorber 5 is used to further improve the buffering effect of the cap beam 2 and reduce the actual load.
