Description

Technical Field

[0001] The utility model relates to the technical field of steel structure bridges, in particular to a steel structure bridge reinforcement mechanism with a shock absorbing function. Background Art

[0002] As an important transportation infrastructure, bridges must have sufficient strength, stability and durability. However, as time goes by, many bridges may experience problems such as structural fatigue and material aging. Coupled with the threat of natural disasters such as earthquakes and storms, it is particularly important to strengthen and renovate existing bridges. Traditional bridge reinforcement methods include adding crossbeams or longitudinal beams, thickening bridge decks, and adding diagonal braces, but these methods often affect the appearance of the bridge and limit the bridge's traffic capacity to a certain extent.

[0003] With the advancement of science and technology, new reinforcement technologies and materials are constantly emerging, such as carbon fiber cloth, glass fiber rods, polymer mortar, etc. These new materials have the characteristics of high strength, light weight, and corrosion resistance, which can effectively improve the bearing capacity and durability of bridges. This invention takes into account the stability and adjustability of the structure, as well as the convenience of installation and maintenance. It is an improvement and innovation of the existing bridge reinforcement technology. Utility Model Content

Such a combination can provide shock-absorbing effects in multiple directions, effectively absorb and disperse vibration energy, and reduce the vibration of the bridge when it is subjected to lateral or longitudinal impact.

[0011] Through the above technical solution, the mounting plate provides a mounting base for the shock absorbing device and provides additional lower support by supporting the fixing rod, thereby enhancing the stability of the entire reinforcement mechanism.

[0012] As a further improvement of the above solution, both sides of the first fixed frame and the second fixed frame are fixedly connected with connecting plates, and threaded holes are provided inside the connecting plates.

[0013] Through the above technical solution, the connecting piece and the threaded hole allow the user to adjust the tightness between the first fixed frame and the second fixed frame according to actual conditions, thereby ensuring the stability and adaptability of the structure.

[0014] As a further improvement of the above solution, the internal threads of the threaded holes are connected with bolts, and the first fixing frame is adapted to the second fixing frame.

[0015] Through the above technical solution, it is firmly fixed by bolts to avoid falling off during use, which may cause certain safety hazards.

[0016] As a further improvement of the above solution, a supporting fixing rod is fixedly connected to the middle of the lower surface of the mounting plate, and a clamping fixing block is fixedly connected to the bottom of the supporting fixing rod.

[0017] Through the above technical solution, the supporting fixing rod and the clamping fixing block provide support and fixing functions for the lower part, ensuring the stability of the entire reinforcement mechanism.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The utility model can effectively absorb and disperse the lateral and longitudinal impact forces generated during earthquakes by arranging the shock-absorbing device, thereby reducing the risk of bridges being damaged by earthquakes. Through the arrangement of components such as triangular support plates, support fixing rods, and clamping fixing blocks, the reinforcement mechanism has high stability and can resist external forces in various directions. Through the design of threaded holes and bolts, the tightness of the reinforcement mechanism can be adjusted according to actual needs to adapt to different working conditions and load requirements.

The design of the shock-absorbing device 6 includes a shock-absorbing spring 602 and an oblique damping rod 604. Such a combination can provide a shock-absorbing effect in multiple directions, effectively absorb and disperse vibration energy, and reduce the vibration of the bridge when it is subjected to lateral or longitudinal impact. The vertical force transmitted is reduced by the vertical damping rod 607, thereby achieving a shock-absorbing effect. Thereby, shock absorption can be achieved in multiple directions. The mounting plate 5 provides an installation basis for the shock absorbing device 6, and provides additional lower support through the supporting fixing rod 12, thereby enhancing the stability of the entire reinforcement mechanism.
