Description

Technical Field

[0001] The invention relates to the technical field of steel structure bridge construction, and in particular to a reinforced steel structure bridge. Background Art

[0002] A steel structure bridge is a bridge built by using steel. Compared with traditional concrete bridges, steel structure bridges have higher strength and rigidity, stronger adaptability, and faster construction speed. Due to these advantages, steel structure bridges have gradually become the mainstream of modern bridge engineering. Steel structure bridges consist of two parts: the main structure of the bridge and the connection structure. The main structure of the bridge consists of the main beam, piers and abutments. The main beam is the load-bearing component of the bridge, usually composed of steel beams and steel plates. The piers are the support and force transmission nodes of the main beam, bearing the bridge load and transferring it to the foundation. The abutments connect the piers and the bridge deck and are an important part of the bridge's bearing capacity.

[0003] The abutment support also absorbs the vibration generated by the passage of vehicles on the bridge deck, thereby eliminating the impact of the vibration of the bridge deck on the bridge deck during the passage of vehicles. The abutment support is generally composed of springs, iron sheets, rubber sheets and external supporting components, which can absorb vibrations in the vertical direction. However, when vehicles are driving on the bridge deck, the vibrations generated not only have vertical directions, but also lateral and oblique vibration waves. These vibration waves in different directions will cause the bridge deck to resonate in different directions. The abutment support in the prior art is difficult to eliminate vibration waves in different directions, causing the bridge deck to be damaged by resonance, affecting the service life of the bridge deck.

[0004] Therefore, we made improvements to this and proposed a reinforced steel structure bridge. Summary of the invention

[0005] (I) The technical problem to be solved by the present invention is: by absorbing the multi-directional vibration waves of the bridge deck, better absorption of the vibration waves of the bridge deck is achieved, and the vibration waves of the bridge deck can be resisted and disturbed to avoid resonance and affect the service life of the bridge deck.

[0021] The reinforced steel structure bridge provided by the present invention has the following beneficial effects:

[0022] 1. When the sealing slider 1 moves downward inside the support tube to absorb the longitudinal shock wave, the inert gas filled in the lower inner part of the support tube is compressed, and the inert gas in the upper inner part of the support tube is under negative pressure, so that the upper sealing slider 3 slides inside the connecting tube close to the supporting tube, and the lower sealing slider 3 slides away from the supporting tube in the connecting tube. Conversely, when the sealing slider 1 moves upward inside the support tube, the lower sealing slider 3 slides inside the connecting tube close to the supporting tube, and the upper sealing slider 3 slides away from the supporting tube in the connecting tube, repeatedly acting on the springs 5 ​​on both sides, so that the springs 5 ​​on both sides can absorb the lateral shock wave well, and the shock wave generated by the vibration of the steel structure bridge deck is absorbed by the lateral shock wave and the longitudinal shock wave through the lateral absorption component and the longitudinal absorption component, thereby realizing the multi-directional absorption of the shock wave generated by the vibration of the steel structure bridge deck, avoiding resonance, and increasing the safety factor of the steel structure bridge deck.

[0023] 2. When the upper and lower sealing sliders 3 move inside the connecting tube, the sealing slider 2 inside the air tube is driven to move up and down, and then the longitudinal vibration wave of the diagonal support seat is counteracted by springs 4 and 3, which not only counteracts and weakens the longitudinal vibration wave generated by the vibration of the longitudinal steel structure bridge deck, but also transmits the force to the supporting column through the diagonal support seat, thereby enhancing the effect of the longitudinal absorption component on absorbing the longitudinal vibration wave.

[0024] 3. In the process of the top column moving up and down, the half gear is driven to rotate back and forth through the tooth groove, and then the turntable is driven to rotate back and forth through the rotating shaft, and then the counterweight ball is driven to swing back and forth around the axis of the rotating seat through the arc rod. The torque and centrifugal force generated during the swing are transmitted to the rotating seat through the rotating shaft, and then transmitted to the diagonal support seat through the rotating seat, to counteract the oblique vibration waves generated by the vibration of the steel structure bridge deck, and further realize multi-directional confrontation and weakening of the vibration waves generated by the steel structure bridge deck, so as to interfere with the vibration waves of the steel structure bridge deck and avoid resonance.

[0025] 4. By adopting spring 2, spring 1, spring 5, spring 4 and spring 3 of different sizes to absorb and counteract the vibration waves of the steel structure bridge deck, the vibration waves generated by the vibration of the steel structure bridge deck can be fully disrupted, so that the vibration of the steel structure bridge deck can be stopped quickly, further improving the service life of the steel structure bridge deck.

[0043] Specifically, when the upper and lower side sealing sliders 3 119 move inside the connecting tube 118, the sealing sliders 2 115 inside the air cylinder 114 are driven to move up and down, and then the longitudinal vibration waves of the diagonal support seat 108 are opposed through the springs 4 116 and 3 111, which not only resist and weaken the longitudinal vibration waves generated by the vibration of the longitudinal steel structure bridge deck 3, but also the force is transmitted to the support column 103 through the diagonal support seat 108, thereby enhancing the effect of the longitudinal absorption component on absorbing the longitudinal vibration waves.

Moreover, in the present invention, spring two 107, spring one 106, spring five 120, spring four 116 and spring three 111 of different sizes are used to absorb and counteract the vibration waves of the steel structure bridge deck 3, which can fully disrupt the vibration waves generated by the vibration of the steel structure bridge deck 3, so that the vibration of the steel structure bridge deck 3 can be stopped quickly, further improving the service life of the steel structure bridge deck 3.

[0044] The longitudinal absorption component includes a support tube 101, in the upper end opening of the support tube 101, a support column 103 is fixedly connected, the lower end of the support column 103 is fixedly connected to a sealing slider 105, the lower end of the sealing slider 105 is fixedly connected to a spring 106, and the upper end of the sealing slider 105 is fixedly connected to a spring 2 107.

[0045] In this embodiment, the lower end of the support tube 101 is fixedly connected with a flange 102, and the lower end of the flange 102 is fixedly installed in the middle of the front and rear sides of the upper end of the pier 2 by expansion bolts, and the outer periphery of the sealing slider 105 is slidably connected to the inner middle part of the support tube 101.

[0046] In this embodiment, the outer periphery of the upper end of the support column 103 is fixedly connected with a flange plate 2 104, the upper end of the flange plate 2 104 is fixedly connected to the front and rear sides of the middle part of the lower end of the steel structure bridge deck 3 by expansion bolts, the lower end of the spring 106 is fixedly connected to the inner bottom wall of the support tube 101, and the upper end of the spring 2 107 is fixedly connected to the inner upper part of the support tube 101.

[0047] Specifically, when people drive vehicles passing by the upper end of the steel structure bridge deck 3, vibration waves in all directions generated by the vibration of the steel structure bridge deck 3 are transmitted to flange 2 104, support column 103, diagonal support seat 108 and U-shaped mounting plate 109, among which the longitudinal vibration waves are transmitted to sealing slider 1 105 through flange 2 104 and support column 103, driving sealing slider 105 to move up and down, and the longitudinal vibration waves are absorbed by spring 1 106 and spring 2 107 at the upper and lower ends of sealing slider 105.

[0048] The lateral absorption component includes a connecting tube 118, and a sealing slider three 119 is slidably connected to the inner middle part of the connecting tube 118. Both ends of the sealing slider three 119 are fixedly connected to a spring five 120. The end of the spring five 120 away from the sealing slider three 119 is fixedly connected to a limiting end plate 121, and a circular hole 122 is opened in the inner middle part of the limiting end plate 121.

[0049] In this embodiment, the end of the connecting tube 118 close to the supporting tube 101 is fixedly connected to the outer peripheral opening of the supporting tube 101, and the end of the connecting tube 118 away from the supporting tube 101 is fixedly connected to the side opening of the gas cylinder 114 close to the supporting tube 101, and the interiors of the supporting tube 101, the connecting tube 118 and the gas cylinder 114 are all filled with inert gas.

[0050] Specifically, when the sealing slider 105 moves downward inside the support tube 101 to absorb the longitudinal shock wave, the inert gas filled in the lower part of the support tube 101 is compressed, and the inert gas in the upper part of the support tube 101 is under negative pressure, so that the upper sealing slider 119 slides closer to the support tube 101 inside the connecting tube 118, and the lower sealing slider 119 slides away from the support tube 101 in the connecting tube 118. Conversely, when the sealing slider 105 moves upward inside the support tube 101, the lower sealing slider 119 slides in the connecting tube 118. The interior of the cylinder 118 slides close to the supporting cylinder 101, and the sealing slider three 119 on the upper side slides away from the supporting cylinder 101 when connecting the cylinder 118, repeatedly acting on the springs five 120 on both sides, so that the springs five 120 on both sides can absorb the lateral shock waves well, and the shock waves generated by the vibration of the steel structure bridge deck 3 are absorbed by the lateral shock waves and the longitudinal shock waves through the lateral absorption component and the longitudinal absorption component, thereby realizing multi-directional absorption of the shock waves generated by the vibration of the steel structure bridge deck 3, avoiding resonance, and increasing the safety factor of the steel structure bridge deck 3.

[0051] Working principle: When people drive vehicles passing by the upper end of the steel structure bridge deck 3, the vibration waves generated by the vibration of the steel structure bridge deck 3 in all directions are transmitted to the flange plate 2 104, the support column 103, the diagonal support seat 108 and the U-shaped mounting plate 109, among which the longitudinal vibration waves are transmitted to the sealing slider 1 105 through the flange plate 2 104 and the support column 103, driving the sealing slider 105 to move up and down, and the longitudinal vibration waves are absorbed by the springs 106 and 107 at the upper and lower ends of the sealing slider 105. At the same time, when the sealing slider 105 moves downward inside the support tube 101 to absorb the longitudinal vibration waves, the inert gas filled in the lower inner part of the support tube 101 is compressed, and the inert gas in the upper inner part of the support tube 101 is under negative pressure, so that the upper side The sealing slider three 119 slides inside the connecting tube 118 close to the supporting tube 101, and the sealing slider three 119 on the lower side slides in the connecting tube 118 away from the supporting tube 101. Conversely, when the sealing slider one 105 moves upward inside the supporting tube 101, the sealing slider three 119 on the lower side slides inside the connecting tube 118 close to the supporting tube 101, and the sealing slider three 119 on the upper side slides in the connecting tube 118 away from the supporting tube 101, repeatedly acting on the springs five 120 on both sides, so that the springs five 120 on both sides can absorb the lateral vibration waves well, and the vibration waves generated by the vibration of the steel structure bridge deck 3 are absorbed by the lateral vibration absorption component and the longitudinal vibration absorption component, thereby realizing the multi-directional absorption of the vibration generated by the steel structure bridge deck 3. The vibration waves generated by the vibration of the longitudinal steel structure bridge deck 3 are not only resisted and weakened, but also the force is transmitted to the support column 103 through the diagonal support seat 108, so as to enhance the effect of the longitudinal absorption component on the absorption of the longitudinal vibration wave. In the process of the top column 112 moving up and down, the half gear 125 is driven to reciprocate through the tooth groove 113, and then the rotating disk 126 is driven to reciprocate through the rotating shaft 124, and then the matching gear 127 is driven to rotate back and forth. The heavy ball 128 swings back and forth around the axis of the rotating seat 123. The torque and centrifugal force generated during the swing are transmitted to the rotating seat 123 through the rotating shaft 124, and then transmitted to the diagonal support seat 108 through the rotating seat 123, so as to resist the oblique vibration wave generated by the vibration of the steel structure bridge deck 3, and further realize multi-directional resistance and weakening of the vibration wave generated by the steel structure bridge deck 3, so as to interfere with the vibration wave of the steel structure bridge deck 3 and avoid resonance. Moreover, in the present invention, spring two 107, spring one 106, spring five 120, spring four 116 and spring three 111 of different sizes are used to absorb and resist the vibration wave of the steel structure bridge deck 3, which can fully disrupt the vibration wave generated by the vibration of the steel structure bridge deck 3, so that the vibration of the steel structure bridge deck 3 can be quickly stopped.The service life of the steel structure bridge deck 3 is further improved.
