A pre-embedded bridge shock absorber

Abstract

The invention discloses a pre-embedded bridge shock absorber, which relates to the field of bridge construction and includes a prefabricated bridge panel. The pre-embedded shock-absorbing sheet groups are evenly arranged in multiple groups along the length direction of the prefabricated bridge deck, and the two sides of the multiple groups of pre-embedded shock-absorbing sheet There are prestressed component connections between the side support plates. In the pre-embedded shock-absorbing sheet group of the shock-absorbing bracket of the present invention, multiple groups of evenly arranged shock-absorbing connectors are connected between the lower steel plate and the upper steel plate, and the shock-absorbing springs inside the shock-absorbing connectors play a major role in buffering. The effect of vibration, and the two sides of the corresponding support seat on the lower steel plate and the upper steel plate are welded with elastic steel bars bent into a semicircle shape, which has a certain ability to absorb vibration.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a pre-embedded bridge damping sheet. Background technique [0002] Due to the long-term bearing of the weight of the vehicle and the vibration of the vehicle when the vehicle is running, the bridge panel will cause the bridge panel to crack. Therefore, it needs to be repaired, inspected and replaced regularly to avoid accidents. In the existing prefabricated bridge panels, the interior of the prefabricated bridge panels is usually composed of criss-cross steel brackets, which have poor absorption capacity for vibrations generated when vehicles are running, and cannot effectively absorb shocks. The traditional bridge panels are only at the top and bottom Reinforcement bars are installed, and when forces in different directions occur, they cannot be fully absorbed. In traditional prefabricated panel production tools, the steel bars are stretched and suspended in advance. The gene...

In the existing prefabricated bridge panels, the interior of the prefabricated bridge panels is usually composed of criss-cross steel brackets, which have poor absorption capacity for vibrations generated when vehicles are running, and cannot effectively absorb shocks. The traditional bridge panels are only at the top and bottom Reinforcement bars are installed, and when forces in different directions occur, they cannot be fully absorbed. In traditional prefabricated panel production tools, the steel bars are stretched and suspended in advance. The general steel bar stretching machine can only better complete the same height. Multiple steel bars distributed in parallel intervals are stretched and erected in the air. However, due to the complex force of the prefabricated slab, it is necessary to set up an interlayer capable of bearing multi-directional forces. However, the traditional steel bar stretching machine cannot complete the laying of the interlayer. Therefore, a convenient It is necessary to carry out a variety of sandwich structures and prefabricated panel frame structures with easy-to-adjust strength
