Description

Technical Field

[0001] This invention relates to the field of public infrastructure, and in particular to a pedestrian overpass staircase and its processing method. Background Technology

[0002] Currently, with the rapid development of urban construction, in areas with high pedestrian traffic, in order to avoid conflicts between vehicle and pedestrian traffic and affect pedestrian safety, it is necessary to add pedestrian overpasses according to the pedestrian traffic volume, so as to achieve the effect of separating pedestrians and vehicles and thus reduce the occurrence of traffic accidents. However, currently, the anti-slip facilities on the stairways of steel-structured pedestrian bridges all use post-installed anti-slip strips. After the stairway paving is completed, the anti-slip strips are fixed to the paving layer with bolts. The anti-slip strips are made of different materials, such as stainless steel, stainless steel with embedded diamond abrasive, or stainless steel with embedded rubber strips. However, because they are all installed after the fact and fixed to the stairway paving with bolts or rivets, subsequent investigations of steel-structured pedestrian bridges have found that after a period of use, these anti-slip strips can deform, fall off, or warp due to collisions and friction between pedestrians going up and down the stairways, and collisions from foot pedals when non-motorized vehicles are pushed along the edges. There may also be hollow areas or gaps in the anti-slip area. When pedestrians step on them, the anti-slip strips are in a cantilevered warped state. Repeated exposure to this state can easily cause the rivets in the middle of the anti-slip strips to fall off, and the anti-slip strips to break and deform, thus affecting the safety of pedestrians going up and down the stairways. Especially in rainy or snowy weather, pedestrians are more likely to bump into, slip, or trip, posing a significant safety hazard. Furthermore, at the junction of staircases and ramps, the anti-slip strips are severely detached. In areas where the anti-slip strips are no longer protected, rainwater and other damage can seep into the existing anti-slip strips along their edges, causing durability issues such as cracking and detachment of the paving under the existing anti-slip strips, and corrosion of the steel plates. This, in turn, leads to the detachment of other anti-slip strips.

[0003] In summary, the current practice of using anti-slip strips on the stairways of steel structure pedestrian overpasses has certain limitations, and further optimization is urgently needed considering factors such as human safety and the durability of the overpass. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a pedestrian overpass stairway and its processing method, which can solve the problems of deformation, detachment, and lifting of anti-slip strips, thereby enhancing the safety of pedestrian passage.

[0005] The specific technical solution of this invention is as follows:

[0009] Metal pads connected to the upper surface of the horizontal plate of the stairway;

[0010] An anti-slip strip, comprising a horizontal section and a vertical section, wherein the horizontal section of the anti-slip strip is welded to the metal pad, and the vertical section of the anti-slip strip is welded to the vertical plate of the stairway, and the anti-slip strip, the metal pad, the horizontal plate of the stairway, and the vertical plate of the stairway form an accommodating space;

[0011] Supporting material that fills the receiving space and is laid on the horizontal slab of the stairway.

[0012] Preferably, the horizontal plate of the stairway is made of steel plate, the metal pad is made of stainless steel, and the metal pad is connected to the horizontal plate of the stairway by welding.

[0013] Preferably, welding is performed at the lower ends of both sides of the metal pad where they meet the horizontal plate of the staircase.

[0014] Preferably, the anti-slip strip is made of stainless steel; the lower end face of the horizontal section of the anti-slip strip at the end away from the vertical section is in close contact with the upper end face of the metal pad, and the end of the horizontal section of the anti-slip strip at the end away from the vertical section is welded to the metal pad.

[0015] Preferably, the vertical plate of the stairway is made of steel plate, the upper end of the vertical plate is higher than the upper end of the horizontal plate of the stairway, the inner wall of the vertical section of the anti-slip strip is in close contact with the outer wall of the vertical plate of the stairway, and the lower end of the vertical section of the anti-slip strip is welded to the outer wall of the vertical plate of the stairway.

[0016] Preferably, the supporting material is mortar.

[0017] Preferably, the supporting material laid on the horizontal plate of the stairway is higher than or equal to the upper surface of the metal pad and lower than the upper surface of the anti-slip strip.

[0018] Preferably, the upper end face of the horizontal section of the anti-slip strip has a groove, and the groove is filled with diamond powder.

[0019] Preferably, the pedestrian overpass stairway further includes: two load-bearing steel beams arranged opposite each other; the two ends of the horizontal slab of the stairway are respectively connected to the two load-bearing steel beams; and the two ends of the vertical slab of the stairway are respectively connected to the two load-bearing steel beams.

[0020] A method for processing pedestrian overpass stairways as described above, the method comprising the following steps:

[0021] Weld the metal pads to the upper surface of the horizontal slab of the staircase.

[0022] The horizontal section of the anti-slip strip is welded to the metal pad, and the vertical section of the anti-slip strip is welded to the vertical plate of the stairway, so that the anti-slip strip, the metal pad, the horizontal plate of the stairway, and the vertical plate of the stairway form an accommodating space;

Finally, the anti-slip strips in the pedestrian bridge stairway can be directly fabricated on the horizontal and vertical slabs in the factory, eliminating the need for on-site installation. This greatly improves on-site installation efficiency and saves time.

[0034] In order to solve the problems of deformation, detachment, and warping of the anti-slip strip 4, and thus enhance pedestrian safety, this application proposes a pedestrian overpass stairway. Figure 1 This is a cross-sectional view of one of the steps of the pedestrian overpass staircase in an embodiment of the present invention, as shown below. Figure 1 As shown, the pedestrian overpass stairway may include: multiple sequentially arranged step structures, at least one step structure including: a horizontal stairway slab 1 extending in the horizontal direction; a vertical stairway slab 2 extending in the vertical direction, the outer side of the horizontal stairway slab 1 abutting the inner side of the vertical stairway slab 2; a metal pad 3 connected to the upper surface of the horizontal stairway slab 1; an anti-slip strip 4, the anti-slip strip 4 having a horizontal section 41 and a vertical section 42, the horizontal section 41 of the anti-slip strip 4 being welded to the metal pad 3, and the vertical section 42 of the anti-slip strip 4 being welded to the vertical stairway slab 2, the anti-slip strip 4, the metal pad 3, the horizontal stairway slab 1 and the vertical stairway slab 2 forming a receiving space; and a support material 5 filling the receiving space and laid on the horizontal stairway slab 1.

[0035] like Figure 1 As shown, multiple stepped structures are arranged diagonally from bottom to top, gradually increasing in height to allow pedestrians to ascend the pedestrian overpass. At least one stepped structure may include: a horizontal stair slab 1, a vertical stair slab 2, metal pads 3, and anti-slip strips 4. The horizontal stair slab 1 extends horizontally, and the vertical stair slab 2 extends vertically, with the vertical stair slab 2 located outside the horizontal stair slab 1. The outer side (i.e., the right side) of the horizontal stair slab 1 abuts against the inner side of the vertical stair slab 2. To facilitate the later pouring of the supporting material 5 into the accommodating space, ensuring the supporting material 5 fills the space and minimizing leakage from the right side of the accommodating space, the upper surface of the vertical stair slab 2 is higher than the upper surface of the horizontal stair slab 1.

[0036] To secure the horizontal stair slab 1 and vertical stair slab 2 of the pedestrian walkway and enable them to bear the weight of pedestrians, the pedestrian walkway may include two opposing load-bearing steel beams. The horizontal stair slab 1 is made of steel plate. The vertical stair slab 2 can also be made of steel plate. Both ends of the horizontal stair slab 1 are connected to the two load-bearing steel beams. Both ends of the vertical stair slab 2 are also connected to the two load-bearing steel beams. These connections can take various forms, such as bolted connections, welded connections, etc., and are not limited in this application. Through this structure, the load-bearing steel beams, the horizontal stair slab 1, and the vertical stair slab 2 can be connected together, with the load-bearing steel beams supporting the horizontal stair slab 1 and the vertical stair slab 2, thus ensuring a secure installation.

[0037] like Figure 1As shown, the metal pad 3 can be connected to the upper surface of the stair rail horizontal plate 1. The extension direction of the metal pad 3 can be the same as the extension direction of the stair rail horizontal plate 1 in the direction perpendicular to the plane of the paper. The metal pad 3 can extend to the load-bearing steel beams at both ends as needed, or it can not extend to the load-bearing steel beams, and there is a certain distance between it and the load-bearing steel beams, so as to facilitate the filling of the space with the support material 5.

[0038] As a feasible option, the metal pad 3 can be made of stainless steel, and the metal pad 3 is connected to the horizontal plate 1 of the stair rail by welding. This structure ensures that the metal pad 3 and the horizontal plate 1 are integrated into one unit, guaranteeing a secure installation and making separation virtually impossible. The stainless steel metal pad 3 not only ensures a strong connection but also prevents rusting. Furthermore, welding is performed at the lower ends of both sides of the metal pad 3 where it meets the horizontal plate 1, with the welds extending perpendicularly to the plane of the paper. This ensures that all positions of the metal pad 3 are welded, improving the connection strength. Additionally, welding at the lower ends of both sides of the metal pad 3 prevents one side from warping under prolonged stress, thus extending its service life.

[0039] like Figure 1 As shown, the anti-slip strip 4 can have a horizontal section 41 and a vertical section 42. The extension direction of the anti-slip strip 4 can be the same as the extension direction of the horizontal plate 1 of the stairway in the direction perpendicular to the plane of the paper. The anti-slip strip 4 can extend to the load-bearing steel beams at both ends as needed, or it can not extend to the load-bearing steel beams, and there can be a certain distance between it and the load-bearing steel beams, so as to facilitate the accommodation of the filling support material 5 in the space.

[0040] like Figure 1 As shown, the horizontal section 41 of the anti-slip strip 4 is welded to the metal pad 3, and the vertical section 42 of the anti-slip strip 4 is welded to the vertical plate 2 of the stair rail. The anti-slip strip 4, the metal pad 3, the horizontal plate 1 of the stair rail, and the vertical plate 2 of the stair rail form a space for accommodation. The anti-slip strip 4 can be made of stainless steel to avoid corrosion and rust, thus extending its service life. The cross-section of the anti-slip strip 4 is approximately L-shaped. The lower end face of the horizontal section 41 of the anti-slip strip 4, at the end furthest from the vertical section 42, is in close contact with the upper end face of the metal pad 3 to ensure sufficient support when pedestrians step on the anti-slip strip 4 and to prevent deformation and damage. The end of the horizontal section 41 of the anti-slip strip 4 furthest from the vertical section 42 is welded to the metal pad 3. Through the above method, the anti-slip strip 4, the metal pad 3, and the vertical plate 2 of the stair rail can be integrated into one unit, ensuring a firm installation and making it difficult for the anti-slip strip 4 to fall off.

[0041] Furthermore, such as Figure 1As shown, the inner wall of the vertical section 42 of the anti-slip strip 4 is tightly attached to the outer wall of the stair rail vertical plate 2, and the lower end of the vertical section 42 of the anti-slip strip 4 is welded to the outer wall of the stair rail vertical plate 2. In this way, the outer wall of the stair rail vertical plate 2 can abut against and support the inner wall of the vertical section 42 of the anti-slip strip 4, preventing the vertical section 42 of the anti-slip strip 4 from tilting or bending. This reduces the stress on the welded joint between the lower end of the vertical section 42 of the anti-slip strip 4 and the outer wall of the stair rail vertical plate 2, ensuring that the welded joint is not damaged due to excessive stress.

[0042] like Figure 1 As shown, the accommodating space is filled with supporting material 5, which further supports the middle of the horizontal section 41 of the anti-slip strip 4 and the side near the vertical section 42, preventing the anti-slip strip 4 from deforming when pedestrians step on it, thus preventing the welded joints on both sides of the anti-slip strip 4 from being damaged and detached due to excessive force. Other areas on the upper surface of the stairway horizontal plate 1 (excluding the accommodating space) are also covered with supporting material 5 for pedestrians to step on. The supporting material 5 can be made of mortar, allowing it to be laid after the pedestrian overpass stairway is installed. The supporting material 5 laid on the stairway horizontal plate 1 is higher than or equal to the upper surface of the metal pad 3, but lower than the upper surface of the anti-slip strip 4. This structure protects the welded joint between the horizontal section 41 of the anti-slip strip 4 and the metal pad 3 at the end furthest from the vertical section 42, preventing damage when pedestrians or vehicles collide with the edge of the anti-slip strip 4.

[0043] When the anti-slip strip 4 does not extend to the load-bearing steel beam and has a certain distance from the load-bearing steel beam, when filling the space with support material 5, it is necessary to use a template to cover the area between the anti-slip strip 4 and the load-bearing steel beam to prevent the support material 5 from leaking down through the ladder vertical plate 2.

[0044] To increase the friction of the upper surface of the horizontal section 41 of the anti-slip strip 4, such as Figure 1 As shown, the upper end face of the horizontal section 41 of the anti-slip strip 4 may have a groove 43, and the groove 43 is provided with diamond grit 6. The groove 43 may be one or two, and it extends in a direction perpendicular to the paper surface.

[0045] The pedestrian overpass staircase in this application can be processed using the following methods:

[0046] The horizontal board 1 and vertical board 2 of the stairway connected with anti-slip strips 4 can be prefabricated in the factory, and the metal pad 3 can be welded to the upper surface of the horizontal board 1.

[0047] The horizontal section 41 of the anti-slip strip 4 is welded to the metal pad 3, and the vertical section 42 of the anti-slip strip 4 is welded to the vertical plate 2 of the stair rail, so that the anti-slip strip 4, the metal pad 3, the horizontal plate 1 of the stair rail, and the vertical plate 2 of the stair rail form a receiving space. Grooves 43 can be pre-processed on the anti-slip strip 4, and diamond powder 6 is placed in the grooves 43.

[0048] Weld the two ends of the horizontal staircase 1 and the two ends of the vertical staircase 2 to two oppositely positioned load-bearing steel beams, and then transport the pedestrian overpass staircase to the installation site for installation. Alternatively, transport the horizontal staircase 1 and vertical staircase 2, which are connected with anti-slip strips 4, to the installation site for installation on the load-bearing steel beams of the pedestrian overpass. The load-bearing steel beams can be pre-installed on the pedestrian overpass; then, simply wait for the horizontal staircase 1 and vertical staircase 2, connected with anti-slip strips 4, to be transported to the installation site, and then directly install them onto the load-bearing steel beams.

[0049] After the pedestrian overpass staircase is transported to the installation site and installed in conjunction with the overpass, the space to be filled with support material 5 and support material 5 is laid on the horizontal slab 1 of the staircase. This method reduces the weight during transport. After installation in conjunction with the overpass, only the filling of support material 5 needs to be completed. The entire construction process is quick and convenient, and the installation of anti-slip strips 4 can be completed in advance at the factory. If the anti-slip strips 4 extend to the point where they abut against the load-bearing steel beams at both ends, and the metal pads 3 also extend to the point where they abut against the load-bearing steel beams at both ends, then grouting holes and grout outlet holes need to be opened on the metal pads 3 and / or the anti-slip strips 4 to ensure that the support material 5 can be smoothly filled into the space to be filled.

[0050] The anti-slip strip 4 in this application can be designed and prefabricated together with the horizontal slab 1 and vertical slab 2 of the stairway, and welded together for installation. This ensures the anti-slip strip 4 is firmly installed, preventing it from falling off or being damaged, thus guaranteeing installation quality. Secondly, the horizontal section 41 of the anti-slip strip 4 is welded to the metal pad 3, and the vertical section 42 is welded to the vertical slab 2. This ensures the anti-slip strip 4 will not deform, fall off, or warp, reducing the difficulty and cost of later maintenance and significantly extending the service life of the pedestrian overpass stairway. Finally, the anti-slip strip 4 in the pedestrian overpass stairway can be directly fabricated in the factory onto the horizontal slab 1 and vertical slab 2, eliminating the need for on-site installation. This greatly improves the efficiency of on-site installation of the pedestrian overpass stairway and saves time.
