Description

Technical Field

[0001] This utility model relates to the field of bridge infrastructure technology, and more specifically to a pedestrian walkway for bridges. Background Technology

[0002] As an important component of bridge deck ancillary facilities, pedestrian walkways primarily serve to provide working access for maintenance personnel during inspections and repairs, while also providing passage for communication and signal cables. Therefore, pedestrian walkways must be robust, resilient, and durable, and also easy to install.

[0003] A Chinese patent (publication number CN209759996U, publication date 2019.12.10) discloses a fiber-reinforced composite walking slab, comprising several central stiffening ribs, secondary outermost stiffening ribs, and outermost stiffening ribs of equal height vertically arranged below the panel, wherein the vertical stiffness of the outermost stiffening ribs is greater than that of the central stiffening ribs. Simultaneously, multiple layers of anisotropic fiber mats are disposed in the panel and each stiffening rib. When the same live load is applied to different lateral positions, the vertical deflection of the fiber-reinforced composite walking slab is the same, exhibiting very high lateral strength and high impact resistance.

[0004] To facilitate manufacturing, the aforementioned pedestrian walkways have smooth tread surfaces. However, considering that bridge walkways are located at high altitudes and are often exposed to the elements, smooth surfaces are prone to slipping in rain or snow. Therefore, to ensure the safety of bridge maintenance personnel walking on the walkways, it is essential to address the issue of surface anti-slip properties.

[0005] On the other hand, while composite pedestrian slabs are lightweight and easy to transport and handle, they can be blown away by wind on bridges, potentially causing traffic accidents if they fall onto the roadway. Current solutions involve additional metal fasteners along the edges for securing the slabs, but metal components are less durable than composite materials. With aging, if these fasteners corrode and deteriorate, high wind pressure can cause them to break, leading to the slabs being lifted. Therefore, effectively reducing wind pressure loads through slab construction can lower the pressure on the fasteners and increase safety margins.

[0006] In summary, how to provide a non-slip, breathable bridge walkway that reduces the risk of slipping for workers under adverse environmental conditions such as rain and snow, effectively reduces the uplift load generated by ambient wind, and improves safety reserves is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of this, the present invention provides a bridge walkway that is anti-slip and breathable, thereby reducing the risk of workers slipping in adverse environmental conditions such as rain and snow, effectively reducing the lifting load generated by ambient wind, and improving safety reserves.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A bridge walkway includes: a board body, wherein a plurality of stiffening ribs are evenly distributed along the length of the bottom end surface of the board body, and the top end surface of the board body is a tread surface, wherein a plurality of anti-slip raised stripes and a plurality of ventilation strip holes are evenly distributed along the length of the top end surface of the board body, wherein the anti-slip raised stripes and the ventilation strip holes are all disposed between two adjacent stiffening ribs, and the anti-slip raised stripes and the ventilation strip holes are spaced apart along the length of the board body.

[0010] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a bridge walkway. The stiffening ribs on this walkway improve the vertical stiffness of the slab, the anti-slip raised stripes provide anti-slip properties, and the ventilation strips allow for ventilation and reduce wind pressure. Furthermore, the anti-slip raised stripes are positioned between the stiffening ribs, reinforcing the cross-section. The anti-slip raised stripes and ventilation strips are spaced apart along the length of the slab, ensuring uniform vertical stiffness. Therefore, this walkway achieves anti-slip and ventilation while maintaining its strength, reducing the risk of slippage for workers in rainy or snowy conditions and the risk of the walkway being lifted by ambient wind.

[0011] Furthermore, the plate body has a plurality of ventilation strip holes evenly distributed at intervals along its width direction.

[0012] The beneficial effects of adopting the above technical solution are: it can ensure the vertical stiffness of the walking board and avoid the problem of reducing the strength of the board by using a continuous strip hole.

[0013] Furthermore, the anti-slip raised stripes are arranged along the width direction of the plate.

[0014] The beneficial effects of adopting the above technical solution are: when using the pultrusion process to manufacture composite material walking boards, the anti-slip raised stripes can also be directly formed during pultrusion, while the ventilation strip holes can be made by post-processing.

[0015] Furthermore, the plurality of the anti-slip raised stripes are arranged at intervals along the width direction of the plate.

[0016] The beneficial effects of adopting the above technical solution are: when using molding process to manufacture composite material walking boards, the anti-slip raised stripes and ventilation strip holes can be formed in one step by the mold without the need for subsequent processing.

[0017] Furthermore, the top surface of the plate has drainage inclined surfaces on both sides of the ventilation strip hole, with the inclined direction of both sides being inclined towards the ventilation strip hole.

[0018] The beneficial effects of adopting the above technical solution are: rainwater can automatically flow through the drainage inclined surface to the ventilation strip holes for discharge, avoiding the accumulation of a lot of rainwater on the tread surface of the board and splashing when workers walk on it.

[0019] Furthermore, two adjacent panels are joined together by a mortise and tenon structure, wherein the stiffening rib located on one end of the panel has a tenon, and the stiffening rib located on the other end of the panel has a tenon groove, and the tenon is inserted into the tenon groove on the adjacent panel.

[0020] The beneficial effect of adopting the above technical solution is that it facilitates the splicing of multiple panels.

[0021] Furthermore, adjacent plates are connected by connecting plate bolts.

[0022] The beneficial effects of adopting the above technical solution are: ensuring the stability of the boards after splicing, and preventing the boards from warping and shaking when stepped on. Attached Figure Description

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] This invention addresses the issue that current mainstream composite material pedestrian treads, in order to ensure ease of manufacturing, all have smooth tread surfaces, failing to consider the slippage problem of the tread surface under adverse conditions such as rain and snow on bridges. Furthermore, since the tread surface is a single, flat surface, it will bear a significant uplift load under ambient wind conditions.

[0034] This utility model mainly uses raised anti-slip stripes to achieve the purpose of anti-slip, and sets ventilation strip holes to achieve the purpose of ventilation and reducing wind pressure. The specific raised anti-slip stripes and strip holes need to be designed and arranged according to the processing method and the vertical stiffness of the walking board.

[0035] For details, see Figure 1 and Figure 2This utility model discloses a bridge walking board, which can be a fiber reinforced composite material walking board, including: a board body 1, with a plurality of stiffening ribs 2 evenly distributed along its length on the bottom end surface of the board body 1, and the top surface of the board body 1 is a tread surface, with a plurality of anti-slip raised stripes 3 and a plurality of ventilation strip holes 4 evenly distributed along its length. The anti-slip raised stripes 3 and ventilation strip holes 4 are all arranged between two adjacent stiffening ribs 2, and the anti-slip raised stripes 3 and ventilation strip holes 4 are arranged at intervals along the length of the board body 1.

[0036] When composite material walking slabs are manufactured using the pultrusion process, the walking slab type is as follows: Figure 2 As shown. The anti-slip raised stripes 3 are arranged along the width of the plate 1, allowing for direct forming during pultrusion. These stripes are positioned between stiffening ribs to reinforce the cross-section. The ventilation slots 4 are created through post-processing. To ensure the vertical stiffness of the walkway slab, the ventilation slots 4 are spaced apart along the stiffening ribs, with a minimum interval of 3cm. For ease of processing, the ventilation slots 4 are also positioned between stiffening ribs. Furthermore, the ventilation slots 4 and the anti-slip raised stripes 3 should be spaced apart to ensure uniform vertical stiffness of the walkway slab.

[0037] When composite material walking treads are manufactured using a molding process, the walking tread type is as follows: Figure 3 As shown. The anti-slip raised stripes 3 and the ventilation strip holes 4 can be formed in one step using a mold, without the need for post-processing. The anti-slip raised stripes 3 can be arranged at intervals along the length of the stiffening ribs, with an interval of no more than 10cm.

[0038] Therefore, this utility model, taking into account pultrusion and molding processes, can achieve the purpose of anti-slip and ventilation while ensuring the strength of the pedestrian slab, thereby reducing the risk of workers slipping on the bridge pedestrian slab in rainy or snowy environments and the risk of the pedestrian slab being lifted up by the wind.

[0039] In some embodiments, such as Figure 5 As shown, on the top surface of the board 1, on both sides of the ventilation slot 4, there are drainage inclined surfaces 5, both inclined towards the ventilation slot 4. In this way, rainwater can automatically flow through the drainage inclined surfaces to the ventilation slots and be discharged, avoiding the problem of excessive rainwater accumulation on the tread surface of the board, which can easily cause splashing when workers walk on it.

[0040] In other embodiments, such as Figure 4 As shown, two adjacent plates 1 are connected by a mortise and tenon structure. The stiffening rib 2 located on one end of the plate 1 has a splicing tenon 6, and the stiffening rib 2 located on the other end of the plate 1 has a splicing tenon 7. The splicing tenon 6 is inserted into the splicing tenon 7 on the adjacent plate 1.

[0041] The two adjacent plates 1 are connected by bolts through connecting plate 8.

[0042] In this embodiment, multiple boards can be spliced ​​together according to the actual length requirements of the walking board. The splicing position is further fixed by bolts through the connecting plate, thereby achieving the stability of the board splicing and avoiding splicing gaps between the splicing tenon 6 and the splicing mortise 7 due to processing errors, which would cause the ends of the board to warp and make abnormal noises when stepping on the walking board.

[0043] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
