[0002] In recent years, with the construction of cross-sea, cross-river, and interchange bridge projects, the construction environment has become increasingly complex. The construction site does not have the conditions to transport materials and equipment, and cannot provide the necessary working platform for the construction project, which brings certain difficulties to the construction of bridge projects. To address this problem, steel frame bridges, as a temporary project, can provide working platforms and transportation channels for the construction project, thereby providing the necessary basic conditions for the construction of bridge projects, which is conducive to shortening the construction period and improving construction efficiency.
[0003] In order to prevent passers-by and vehicles from slipping during use, an anti-skid layer is installed on the bridge deck of a small steel frame bridge. The anti-skid layer will be worn during long-term use, which greatly reduces its anti-skid performance and needs to be replaced with a new anti-skid layer in time. However, since the current anti-skid layer is fixed to the bridge deck, the entire bridge deck needs to be replaced at the same time as the anti-skid layer, which greatly increases the replacement time and cost.

[0026] [First embodiment]
[0027] like Figure 1-4 The figure shows a steel frame bridge with an anti-skid structure provided by the first embodiment of the utility model, comprising a bridge deck 1, to which two first guardrails 2 are fixedly connected, and the two first guardrails 2 are symmetrically arranged on the bridge deck 1.
[0028] Reference Figure 2-3A plurality of replacement structures 3 are provided on the bridge deck 1. The replacement structure 3 is mainly composed of a replacement groove 31. The replacement groove 31 is opened on the bridge deck 1. A replacement plate 32 is clamped in the replacement groove 31. A rubber pad 33 is fixedly connected to the upper surface of the replacement plate 32. The replacement plate 32 is clamped in the replacement groove 31. The rubber pad 33 is flush with the upper surface of the bridge deck 1 to prevent large protrusions from affecting vehicle driving. When the rubber pad 33 is severely worn, the replacement plate 32 can be taken out of the replacement groove 31 to replace the damaged rubber pad 33. The replacement operation is convenient and other undamaged rubber pads 33 do not need to be replaced, which can save replacement time and replacement cost.
[0029] like Figure 3 As shown, the two sides of the replacement plate 32 are fixedly connected with connecting blocks 34, and the inner walls of the two sides of the replacement groove 31 are respectively provided with connecting grooves 35, and the connecting blocks 34 are matched with the connecting grooves 35 in size. When installing a new rubber pad 33, the replacement plate 32 is inserted into the replacement groove 31, and the two connecting blocks 34 can be respectively inserted into the connecting grooves 35, so that the installation of the replacement plate 32 is more stable; the two sides of the replacement groove 31 are respectively slidably inserted with sliding rods 36, and the connecting blocks 34 are provided with limiting grooves 37, and the sliding rods 36 are matched with the limiting grooves 37 in size. When the replacement plate 32 is installed, the two sliding rods 36 can be respectively inserted into the limiting grooves 37 to further ensure the stability of the installation. A spring 38 is sleeved on the sliding rod 36, and one end of the spring 38 is fixedly connected to the bridge deck 1, and the other end of the spring 38 is fixedly connected to one end of the sliding rod 36. When the sliding rod 36 is pulled outward, the spring 3 8 is in a retracted state, so in the process of inserting the connecting block 34 into the connecting groove 35, when the sliding rod 36 contacts the limiting groove 37, the sliding rod 36 is stuck into the limiting groove 37 under the action of the rebound elastic force of the spring 38, making the operation more convenient, and the spring 38 limits the sliding rod 36 to strengthen the connection effect with the limiting groove 37, and the lower surface of the replacement groove 31 is provided with a drainage hole 39. When water flows into the replacement groove 31 through the gap, it will flow out through the drainage hole 39 to prevent water from accumulating in the replacement groove 31. Two symmetrically arranged inclined plates 310 are fixedly connected in the replacement groove 31, and two symmetrically arranged inclined grooves 311 are provided on the lower surface of the replacement plate 32. The inclined grooves 311 are adapted to the size of the inclined plates 310. The two inclined plates 310 can divert water to the drainage hole 39, and the inclined grooves 311 fit the inclined plates 310 to avoid the formation of large gaps.
[0030] Reference Figure 4A diversion structure 4 is provided on the bridge deck 1, and the diversion structure 4 is mainly composed of a sidewalk 41. The sidewalk 41 is fixedly connected to one side of the bridge deck 1, and an anti-skid mat 42 is fixedly connected to the sidewalk 41. A second guardrail 43 is fixedly connected to the sidewalk 41. The sidewalk 41 can realize the diversion of people and vehicles, which can make the staff safer when passing. The anti-skid mat 42 can prevent pedestrians from slipping when passing. The second guardrail 43 further protects pedestrians. A plurality of circular holes 44 are opened on the sidewalk 41, and a plurality of lower gutters 45 are opened on the sidewalk 41. The circular holes 44 are connected with the lower gutters 45. The water on the sidewalk 41 will flow to the lower gutters 45 through the circular holes 44, and then will flow out of the sidewalk 41 along the lower gutters 45 to prevent water from accumulating on the sidewalk 41.
[0031] The specific working process of this embodiment is:
[0032] The replacement plate 32 is stuck in the replacement groove 31, and the rubber pad 33 is flush with the upper surface of the bridge deck 1, which can prevent large protrusions from affecting the driving of the vehicle. When the rubber pad 33 is severely worn, the replacement plate 32 can be taken out of the replacement groove 31, and the damaged rubber pad 33 can be replaced. The replacement operation is convenient and other undamaged rubber pads 33 do not need to be replaced, which can effectively save replacement time and replacement costs.
[0033] When installing a new rubber pad 33, while inserting the replacement plate 32 into the replacement groove 31, the two connecting blocks 34 can be respectively inserted into the connecting grooves 35, which can make the installation of the replacement plate 32 more stable. After the replacement plate 32 is installed, the two sliding rods 36 can be respectively inserted into the limiting grooves 37 to further improve the stability of the installation. When the sliding rod 36 is pulled outward, the spring 38 is in a contracted state. Therefore, when the connecting block 34 is inserted into the connecting groove 35, when the sliding rod 36 contacts the limiting groove 37, The slide bar 36 is then snapped into the limit groove 37 under the action of the rebound force of the spring 38, making the operation more convenient, and the spring 38 limits the slide bar 36 to strengthen the connection effect with the limit groove 37. When water flows into the replacement groove 31 through the gap, it will flow out through the drain hole 39 to prevent water from accumulating in the replacement groove 31. The two inclined plates 310 can guide the water to the drain hole 39, and the inclined groove 311 fits with the inclined plate 310 to avoid the formation of a large gap.
[0034] In addition, the sidewalk 41 can separate pedestrians from vehicles, making it safer for workers to pass through. The anti-slip mat 42 can prevent pedestrians from slipping when passing through. The second guardrail 43 provides further protection for pedestrians. The water on the sidewalk 41 will flow through the circular hole 44 to the lower gutter 45, and then will flow out of the sidewalk 41 along the lower gutter 45 to prevent water from accumulating on the sidewalk 41.
