Description

Technical Field

[0001] The utility model relates to the technical field of beam body anti-falling equipment, in particular to a U-shaped steel slope adjustment structure. Background Art

[0002] At present, there are many types of anti-falling beam devices in China. Traditional anti-falling beam devices include anchor bolt type, block type, steel bracket type, etc. The more advanced ones include U-shaped steel anti-falling beam devices, which buffer and release the force transmitted from the upper part of the bridge through the structure of U-shaped steel, prevent earthquake damage to the bridge, and enhance the seismic resistance of the bridge. The main working principle of the U-shaped steel anti-falling beam device is: when the bridge has a tendency to tilt or fall longitudinally or horizontally due to earthquakes and other reasons, the U-shaped steel is subjected to the force transmitted from the beam, and the U-shaped steel itself stretches forward or backward to generate damping force, which relieves and releases the force transmitted from the beam, thereby enhancing the seismic resistance of the bridge.

[0003] During the construction of bridges, bridges often have longitudinal and transverse slopes. In this case, it is necessary to add a wedge-shaped steel plate or a concrete wedge-shaped block between the bottom of the beam and the U-shaped anti-falling beam device for leveling, so that the top surface of the U-shaped anti-falling beam device is evenly stressed. However, due to the errors and processing accuracy of actual construction, the purpose of leveling cannot be achieved. In addition, both of the above-mentioned slope adjustment methods have the disadvantages of high construction difficulty and high construction cost. It may cause the U-shaped anti-falling beam device to be partially detached from the beam body, thereby affecting the uniform stress of the U-shaped anti-falling beam device, which will lead to the destruction and failure of the U-shaped anti-falling beam device in the long run.

[0004] Therefore, how to optimize the U-shaped steel anti-falling beam device so that it does not affect its function and can meet the slope adjustment needs of the bridge without modifying the size of local beams and piers, reducing construction difficulty and cost, and making the U-shaped anti-falling beam device widely used in actual engineering is a key issue that we urgently need to solve and study.

[0056] In view of the above technical problems, the utility model provides a variety of slope adjustment methods based on U-shaped steel. The basic function of U-shaped steel is to transmit and release force. While meeting the requirements of anti-falling beams in engineering, the longitudinal and transverse slope adjustment requirements of the beam body can also be met according to the forming slope of the connecting plate of the U-shaped steel.

[0064] The U-shaped steel is formed by setting a forming slope along the opening direction on one or both sides to adjust the slope; or setting a forming slope along the opening direction perpendicular to the U-shaped steel to adjust the slope. Similarly, by setting an inclined hole matching the slope at the upper connecting bolt hole 5 according to the slope, the structural design of the inclined hole ensures the surface contact during the bolt connection, thereby improving the structural stability.

[0065] In summary, the utility model designs a variety of U-shaped steel slope adjustment structures for the connection support of the slope bottom surface of the beam body, and meets the longitudinal and transverse slope connection support requirements of the beam body through the synergistic effect of the U-shaped steel and the slope adjustment plate or only through the structure of the U-shaped steel itself.
