Description

[0002] In the construction of general outdoor parks, some streams and rivers are usually laid out. In order to facilitate people's passage, some small bridges will be built during construction. However, traditional wooden bridges are easily eroded by water vapor during actual use, which is not conducive to long-term use. Therefore, people often use steel structures to build short bridges. Steel frame bridges can facilitate the walking of staff. However, the steel structure bridge structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. The structures are rigidly connected. The force cannot be dispersed when bearing force, resulting in the bridge being often damaged and loose due to long-term force when in use, resulting in safety hazards, which is not conducive to actual use. At the same time, when this type of steel frame bridge is in use, due to its layout outdoors, some water often accumulates on the bridge deck pedals, which can easily cause people to slip.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In actual use, the steel structure bridge can connect the two sides of the stream, which is convenient for people to use. The bridge deck pedals can support people so that they can pass stably. When people walk on the bridge deck pedals, they will apply a downward force to the bridge deck pedals and form vibrations. The bridge deck pedals can be supported by the load-bearing plates and fixed frames at the bottom of the bridge deck pedals. The downward pressure and vibrations of the bridge deck pedals can be transmitted to the pillars through the load-bearing plates. The pressure can be transmitted through the pillars, and then the force can be dispersed through the support plates and force-dividing rods. The support springs and buffer springs can use their own elastic force to limit and support the slider, so that the pressure transmitted from the bridge deck pedals can be offset and effectively buffered, thereby greatly improving the load-bearing capacity of the steel structure bridge, which is beneficial to actual use.

[0016] The diagonal brace can be used to transmit the force received on both sides of the bridge deck pedals to the diagonal brace. At the same time, the inclined setting of the diagonal brace can change the direction of force transmission, thereby changing the force from the up and down direction to the horizontal direction during transmission. The diagonal brace can be guided by the fixed rod one and the fixed rod two, and the diagonal brace can be supported by the connecting spring and the buffer spring two, thereby completing the offset and buffering of the moving force, thereby effectively reducing the vibration of the steel structure bridge during use, making the steel structure bridge more stable and conducive to practical use.

[0017] When in use, the damping rod between the diagonal brace and the fixed frame can support the diagonal brace when the diagonal brace is subjected to force, and the bottom brace at the end of the diagonal brace can further support the diagonal brace. When the diagonal brace is subjected to force and moves horizontally, the bottom brace will deform, thereby buffering the force transmitted to the diagonal brace, so that the diagonal brace can have multiple support points. Through multi-point support and multi-point force dissipation, the interference force to which the steel structure bridge is subjected during use can be made smaller, which is conducive to the long-term and frequent use of the steel structure bridge.

[0018] When used outdoors for a long time, the top plate of the bridge deck is changed to a shape that is high in the middle and low on the sides. In actual use, rainwater can slide down through the slope on the top plate and drain through the drainage holes, making it more difficult for raindrops that fall on the bridge deck to accumulate, reducing the impact of water accumulation on people's travel after rain, greatly improving the anti-slip performance of the steel structure bridge, and effectively preventing water accumulation from corroding the steel structure bridge, thereby further improving the service life of the steel structure bridge and its stability after long-term use.

[0019] When people walk onto the steel structure bridge and step on the top plate, the gravity of the human body will cause the top plate to deform and become flat, which is beneficial for practical use. The fixed block and the connecting block at the bottom can be pressed down into the sliding cavity through the top plate, so that the gas at the bottom of the sliding cavity can be discharged, and the discharged gas will be discharged into the air intake channel of the next bridge deck pedal through the connecting channel and the air intake channel. The conducted gas can be introduced into the sliding cavity of the next bridge deck pedal through the air intake channel, so that the sealing slide seat on the next bridge deck pedal can be pushed up, so that the top plate can be lifted higher, and the inclination can be increased so that the water droplets hanging on the top plate can be better discharged, avoiding the residual water droplets hanging on the wall from affecting people's walking, which is beneficial for practical use.

[0031] Furthermore, in specific implementation and actual use, the steel structure bridge 1 can connect the two sides of the stream, which is convenient for people to use. The bridge deck pedal 109 can support people so that they can pass stably. When people walk on the bridge deck pedal 109, a downward force will be applied to the bridge deck pedal 109 and vibration will be generated. The bridge deck pedal 109 can be supported by the load-bearing plate 146 and the fixing frame 108 at the bottom of the bridge deck pedal 109. The downward pressure and the vibration generated by the bridge deck pedal 109 can be transmitted to the pillar 138 through the load-bearing plate 146. The pressure received can be transmitted through the pillar 138, and then the force received can be dispersed through the support plate 137 and the force dividing rod 143. The support spring 136 and the buffer spring 140 can use their own elastic force to limit and support the slider 135, so that the pressure transmitted from the bridge deck pedal 109 can be offset and effectively buffered, thereby greatly improving the bearing capacity of the steel structure bridge 1, which is beneficial to actual use.

[0032] Among them, the top of the fixing frame 108 is fixedly connected to both sides of the bottom of the bridge deck pedal 109, the end of the fixing frame 108 away from the bridge deck pedal 109 is fixedly connected to the support column 102 and the column 103, the two ends of the fixing rod 112 are fixedly connected to the support column 102 and the column 103, the two ends of the limiting plate 110 are fixedly connected with the guide column 134, the end of the guide column 134 away from the limiting plate 110 is slidably connected to the middle part of one end of the diagonal support frame 106, the inside of the guide column 134 is slidably connected to the limiting rod 139, the end of the limiting rod 139 away from the guide column 134 is fixedly connected to the diagonal support frame 106, the outer periphery of the limiting rod 139 is sleeved with a connecting spring 144, the connecting spring 144 is arranged between the guide column 134 and the inner wall of the diagonal support frame 106, the upper part of the diagonal support frame 106 passes through the fixing frame 108, and the diagonal support frame 106 is slidably connected to the fixing frame 108;

[0033] Furthermore, in a specific implementation, the force received on both sides of the bridge deck pedal 109 can be transmitted to the diagonal support frame 106 through the diagonal support rod 145. At the same time, the inclined setting of the diagonal support rod 145 can change the direction of force transmission, so that the force can be changed from the up and down direction to the horizontal direction during transmission. The diagonal support frame 106 can be guided by the fixed rod 111 and the fixed rod 2 112, and the diagonal support frame 106 can be supported by the connecting spring 144 and the buffer spring 2 142, thereby completing the offset and buffering of the moving force, thereby effectively reducing the vibration of the steel structure bridge 1 during use, making the steel structure bridge 1 more stable and conducive to actual use.

[0034] Among them, the top of the diagonal brace 106 is fixedly connected to the diagonal brace rod 145, the top of the diagonal brace rod 145 is slidably connected to the bridge deck pedal 109, one end of the diagonal brace 106 is fixedly connected to the bottom brace 117, the middle of the bottom brace 117 is penetrated by a fixed rod 111, both ends of the fixed rod 111 are fixedly connected to the middle of the limiting groove 105, the bottom brace 117 is slidably connected to the inner side of the limiting groove 105, and the limiting groove 105 is opened at the intersection of the support column 102 and the column 103 At the lower part of the end close to the inclined support frame 106, the lower part is slidably connected to the inner side of the opening 116, and the opening 116 is opened in the middle part of the lower side of the fixed frame 108. A limiting sleeve 115 is arranged between the fixed frame 108 and the inclined support frame 106. The limiting sleeve 115 is sleeved on the outer periphery of the second fixed rod 112. The upper and lower parts of the limiting sleeve 115 are fixedly connected to the damping rod 141. The end of the damping rod 141 away from the limiting sleeve 115 is rotatably connected to the inclined support frame 106 and the fixed frame 108 respectively.

[0035] Furthermore, in a specific implementation, when in use, the damping rod 141 between the diagonal support frame 106 and the fixed frame 108 can support the diagonal support frame 106 when the diagonal support frame 106 is subjected to force, and the bottom support frame 117 at the end of the diagonal support frame 106 can further support the diagonal support frame 106. When the diagonal support frame 106 is subjected to force and translates, the bottom support frame 117 will deform, thereby completing the buffering of the force transmitted to the diagonal support frame 106, so that the diagonal support frame 106 can have multiple support points. Through multi-point support and multi-point force dissipation, the interference force to which the steel structure bridge 1 is subjected during use can be made smaller, which is beneficial to the long-term and frequent use of the steel structure bridge 1.

[0036] Among them, a top cavity 133 is opened at the top of the bridge deck pedal 109, and a top plate 114 is arranged inside the top cavity 133. A fixed block 121 is fixedly connected to the middle of the bottom end of the top plate 114. A connecting block 122 is rotatably connected to the bottom of the fixing block 121. A sealing slide 126 is fixedly connected to the bottom of the connecting block 122. The sealing slide 126 is slidably connected to the inside of the slide cavity 123. The slide cavity 123 is opened in the middle of the bridge deck pedal 109. Both ends of the sealing slide 126 are penetrated by evenly distributed guide rods 120. The sealing slide 126 is slidably connected to the guide rod 120. The upper and lower parts of the outer periphery of the guide rod 120 are sleeved with reset springs 127. The reset springs 127 are arranged at the upper and lower parts of the sealing slide 126. The guide rods 120 are fixedly connected to both sides of the slide cavity 123. The top plate 114 is set to be high in the middle and low on both sides.

[0037] Furthermore, in specific implementation, when used outdoors for a long time, by changing the top plate 114 on the top of the bridge deck pedal 109 to a shape that is high in the middle and low on the sides, rainwater can slide down through the inclined surface on the top plate 114 during actual use, and be discharged through the drainage holes 131, making it more difficult for raindrops falling on the bridge deck pedal 109 to accumulate, thereby reducing the situation where people's travel is affected by water accumulation after rain, greatly improving the anti-slip properties of the steel structure bridge 1, and being beneficial to actual use. At the same time, it can effectively prevent water accumulation from corroding the steel structure bridge 1, thereby further improving the service life of the steel structure bridge 1 and its stability after long-term use.

[0038] Among them, both sides of the bottom of the top plate 114 are fixedly connected with uniformly distributed limit blocks 118, and the limit blocks 118 are slidably connected inside the guide groove 132. The guide grooves 132 are opened on both sides of the top of the bridge deck pedal 109, and both ends of the bridge deck pedal 109 are opened with uniformly distributed drainage holes 131. The upper parts of both sides of the sliding cavity 123 are opened with exhaust channels 130, and the exhaust channels 130 are installed with one-way valves 119. The lower parts of the front and rear sides of the sliding cavity 123 are respectively provided with uniformly distributed intake channels 128 and connecting channels 125, and the intake channels 128 and the connecting channels 125 are installed with one-way valves 124. The adjacent bridge deck pedals 109 are connected by a connecting pipe 129, and the two ends of the connecting pipe 129 are respectively arranged on the inner sides of the intake channels 128 and the connecting channels 125 on the adjacent bridge deck pedals 109;

[0039] Furthermore, in the specific implementation, in actual use, when people walk on the steel structure bridge 1 and step on the top plate 114, the gravity of the human body will cause the top plate 114 to deform and become flat, which is conducive to actual use. The top plate 114 can press the bottom fixing block 121 and the connecting block 122 into the sliding cavity 123, so that the gas at the bottom of the sliding cavity 123 can be discharged, and the discharged gas will be discharged into the next bridge through the connecting channel 125 and the air inlet channel 128. Inside the air inlet hole 128 of the surface pedal 109, the gas conducted can be introduced into the sliding cavity 123 of the next bridge deck pedal 109 through the air inlet hole 128, so that the sealing slide seat 126 on the next bridge deck pedal 109 can be pushed upward, so that the top plate 114 can be lifted higher, and the inclination is increased so that the water droplets remaining on the top plate 114 can be better drained, avoiding the remaining water droplets hanging on the wall from affecting people's walking, which is beneficial to practical use.

[0040] Working principle:

[0041] In actual use, the steel structure bridge 1 can be used to connect the two sides of the stream, which is convenient for people to use. The bridge deck pedal 109 can support people so that they can pass stably. When people walk on the bridge deck pedal 109, a downward force will be applied to the bridge deck pedal 109 and vibration will be generated. The bridge deck pedal 109 can be supported by the load-bearing plate 146 and the fixing frame 108 at the bottom of the bridge deck pedal 109. The downward pressure and vibration generated by the bridge deck pedal 109 can be transmitted to the pillar 138 through the load-bearing plate 146. The pressure received can be transmitted through the pillar 138, and then the force received can be dispersed through the support plate 137 and the force distribution rod 143. The support spring 136 and the buffer spring are used together. 140 can use its own elastic force to limit and support the slider 135, so that the pressure transmitted from the bridge deck pedal 109 can be offset and effectively buffered, thereby greatly improving the load-bearing capacity of the steel structure bridge 1, which is beneficial to practical use. At the same time, the force on both sides of the bridge deck pedal 109 can be transmitted to the diagonal support frame 106 through the diagonal support rod 145. At the same time, the inclined setting of the diagonal support rod 145 can change the direction of force transmission, thereby changing the force from the up and down direction to the horizontal direction during transmission. The diagonal support frame 106 can be guided by the fixed rod 111 and the fixed rod 2 112, and the diagonal support frame 106 can be supported by the connecting spring 144 and the buffer spring 2 142, completing the offset and buffering of the moving force, so that it can have The vibration of the steel structure bridge 1 during use is effectively reduced, so that the steel structure bridge 1 can be more stable, which is beneficial to actual use. At the same time, during use, the damping rod 141 between the diagonal support frame 106 and the fixed frame 108 can support the diagonal support frame 106 when the diagonal support frame 106 is subjected to force, and the bottom support frame 117 at the end of the diagonal support frame 106 can further support the diagonal support frame 106. When the diagonal support frame 106 is subjected to force and translation, the bottom support frame 117 will deform to buffer the force transmitted to the diagonal support frame 106, so that the diagonal support frame 106 can have multiple support points. Through multi-point support and multi-point force elimination, the interference force received by the steel structure bridge 1 during use can be made smaller, which is beneficial to the long-term and frequent use of the steel structure bridge 1. When used outdoors for a long time, by changing the top plate 114 on the top of the bridge deck pedal 109 to a shape that is high in the middle and low on the sides, rainwater can slide down through the inclined surface on the top plate 114 and drain through the drainage holes 131 during actual use, making it more difficult for raindrops that fall on the bridge deck pedal 109 to accumulate, reducing the impact of water accumulation on people's travel after rain, greatly improving the anti-skid performance of the steel structure bridge 1, and being beneficial to actual use. At the same time, it can effectively prevent the steel structure bridge 1 from being corroded by water accumulation, thereby further improving the service life of the steel structure bridge 1 and the stability after long-term use. In actual use, when people walk on the steel structure bridge 1 and step on the top plate 114, the gravity of the human body will cause the top plate 114 to deform and become flat.It is beneficial to practical use. The fixing block 121 and the connecting block 122 at the bottom can be pressed down into the sliding cavity 123 through the top plate 114, so that the gas at the bottom of the sliding cavity 123 can be discharged. The discharged gas will be discharged into the air intake channel 128 of the next bridge deck pedal 109 through the connecting channel 125 and the air intake channel 128. The conducted gas can be introduced into the sliding cavity 123 of the next bridge deck pedal 109 through the air intake channel 128, so that the sealing slide seat 126 on the next bridge deck pedal 109 can be pushed up, so that the top plate 114 can be lifted higher, and the inclination can be increased so that the water droplets remaining on the top plate 114 can be better discharged, so as to avoid the residual water droplets on the wall affecting people's walking, which is beneficial to practical use.
