Detailed Description
The present application is described in further detail below with reference to the attached drawings.
The embodiment of the application discloses steel structure bridge.
Referring to fig. 1, the bridge steel structure includes a bracket 11, the bracket 11 is inserted into the ground or installed and fixed to a pier of a bridge, a base plate 12 is welded and fixed to an upper end of the bracket 11, and the base plate 12 is laid on the bracket 11, so that a vehicle can directly run on the base plate 12 when the bridge is used, and in other embodiments, an asphalt or concrete layer can be laid on the base plate 12 so as to be used for the vehicle to run. When the bridge is constructed, the two adjacent supports 11 are connected by bolts, and then the two supports 11 are welded and fixed by workers. The steel truss 13 is fixed on the support 11, and two ends of the bottom of the steel truss 13 are respectively and fixedly connected with the two supports 11, so that the two adjacent supports 11 are further connected and fixed by the steel truss 13, the steel truss 13 and the supports 11 are firstly connected by bolts, and then the steel truss 13 and the supports 11 are welded and fixed.
The steel truss 13 spans the whole bottom plate 12, two side ends of the steel truss 13 are respectively located at two sides of the bottom plate 12, the two side ends of the steel truss 13 are respectively fixed at two side ends of the bracket 11, and the two side ends of the bottom plate 12 can be welded and fixed on the steel truss 13. Similarly, the rods of the steel truss 13 are connected by bolts, and then the adjacent two rods are welded. Still riveted joint has guardrail 14 on bottom plate 12, and guardrail 14 installation is fixed in the position department of bottom plate 12 both sides end, and guardrail 14 is located the inboard of steel truss 13, and guardrail 14 is convenient for the pedestrian and is held up, and guardrail 14 can also play certain guard action to the vehicle simultaneously, reduces the impact of vehicle to steel truss 13.
Referring to fig. 1, an anti-falling frame 21 is further mounted and fixed on the steel truss 13, the upper end of the anti-falling frame 21 is firstly bolted to the outer side of the steel truss 13, and then the worker welds and fixes the upper end of the anti-falling frame 21 and the steel truss 13. The bottom of the anti-falling frame 21 is a hanging end, the hanging end of the anti-falling frame 21 is positioned on one side of the steel truss 13 far away from the bottom plate 12, and the hanging end of the anti-falling frame 21 is lower than the bottom plate 12 and the steel truss 13.
The anti-falling net 22 is fixedly connected to the anti-falling frame 21, one end of the anti-falling net 22 is hooked and fixed on the suspended end of the anti-falling frame 21, and the other end of the anti-falling net 22 is hooked and fixed on the steel truss 13. The anti-falling net 22 is made of nylon net, and the gap on the anti-falling net 22 is controlled within 10cm, so that the safety protection performance of the anti-falling net 22 is improved. When someone falls onto the fall protection net 22 from the guardrail 14 or finds a short sight, the fall protection net 22 can improve the safety of the falling person and increase the personal safety of the falling person. Meanwhile, in order to prevent a falling person from climbing onto the anti-falling frame 21 along the anti-falling net 22 and jumping into the river, the gap on the anti-falling frame 21 is smaller than 20cm, so that the falling person still cannot jump into the river through the gap on the anti-falling frame 21 when climbing onto the anti-falling frame 21 through the anti-falling net 22, the phenomenon of insufficient height on the bridge is reduced, and the accident rate on the bridge is reduced.
Further, referring to fig. 1 and 2, in order to improve the stability of the anti-falling net 22 on the bridge, a connecting frame 23 is also fixedly connected to the steel truss 13, one end of the connecting frame 23 is connected to the steel truss 13, and the other end of the connecting frame 23 is connected to the anti-falling frame 21. When the connecting frame 23 is installed and fixed, a worker previously bolts the two ends of the connecting frame 23 to the steel truss 13 and the anti-falling frame 21 respectively, then welds the connecting frame 23 and the steel truss 13, and welds and fixes the connecting frame 23 and the anti-falling frame 21. The bottom of link 23 is hung on preventing weighing down net 22, and link 23 is equipped with a plurality ofly on the bridge altogether to utilize a plurality of links to prevent weighing down net 22 and carry out multiple spot position connection hook, and then transfer the stability of preventing weighing down net 22 and connecting on the bridge, reduced the risk of preventing weighing down the tie point of net 22 and bridge and tearing apart, thereby improved the people and dropped when preventing weighing down net 22 and prevented weighing down the stability of net 22, also improved the personal safety that drops the people.
When someone drops to preventing weighing down and nets 22 on, in order to make things convenient for the people that drops to climb to the bridge, still install on link 23 and be fixed with climbing frame 231, climbing frame 231 installs along vertical direction on link 23, and the people that drop of being convenient for like this carry out the gripping to let the people that drop consume less physical power get back to on the bridge.
Referring to fig. 1 and 2, after the person that drops climbs the link 23 through the climbing frame 231, the staff need step on the link 23 and walk to the bottom plate 12, it is very inconvenient, thereby in order to facilitate the person that drops to walk on the link 23, still fixedly connected with walkway plates 232 on the link 23, walkway plates 232 install the side bottom on the link 23, and walkway plates 232 outwards extend, walkway plates 232 weld on the link 23.
The people that drop is climbing the link 23 through climbing frame 231 on the back, the people that drop both hands are gripping the link 23, the foot is stepped on the walking that is slow forward on walking board 232, then gradually walk guardrail 14 department, then the people that drop rolls over guardrail 14 and gets back to on bottom plate 12, and through installation climbing frame 231 and walking board 232 on link 23, the personnel of suing and labouring of also being convenient for save and labouring personnel and save the light life personnel, make the better physical power of personnel of suing and labouring personnel of suing and labouring, simultaneously can also reduce personnel of suing and labouring's physical demands.
Further, referring to fig. 1 and 2, when a person is in a light life, the anti-falling net 22 is easily cut off by a cutter, in order to further protect pedestrians on the bridge, a steel wire mesh 24 is further fixedly installed on the anti-falling frame 21, one end of the steel wire mesh 24 is fixedly welded on the anti-falling frame 21, the other end of the steel wire mesh 24 is fixedly welded on the guardrail 14, and the steel wire mesh 24 is located right below the anti-falling net 22, so that the steel wire mesh 24 can further play a role in protection after the anti-falling net 22 is broken.
Further, referring to fig. 1 and 2, when a pedestrian walks sightseeing on the bottom plate 12, the vehicle running on the bottom plate 12 easily rushes into the crowd, and therefore, in order to reduce the risk that the vehicle running on the bottom plate 12 directly rushes into the crowd, an anti-collision guardrail 31 is further installed and fixed on the bottom plate 12. Anti-collision guardrail 31 is on a parallel with guardrail 14 and installs, and the bottom that reduces anti-collision guardrail 31 is riveted with bottom plate 12, anti-collision guardrail 31 shunts the people car on the bridge, thereby bottom plate 12 goes upward people's lane and lane, the pedestrian walks on the pavement, the vehicle is gone on the lane, make people's car separation, the security of pedestrian's walking has been improved, the stream of people who shuttles back and forth in the vehicle has also been reduced simultaneously, the accident rate on the bridge has been reduced, and when the vehicle on the lane of going loses control, the vehicle at first can bump into on anti-collision guardrail 31, the direct risk of rushing into the crowd of vehicle has been reduced, very big reduction the loss of accident.
The embodiment of the application also discloses a production process of the bridge steel structure.
