Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and specifically, to an externally cantilevered walking platform. Background Art

[0002] At present, for the cantilever construction method adopted during bridge construction, operations are carried out on precisely constructed construction platforms on both sides of the bridge pier. By using high-strength steel formwork as the key mold for concrete pouring, the process of gradually cantilever pouring or assembling beam segments from both sides of the bridge structure towards the mid-span direction in a balanced and orderly manner is realized.

[0003] During this process, for the erection of the bridge deck construction platform, mainly multiple working scaffolds are erected on the ground or directly rely on the steel formwork as the construction platform. However, when erecting working scaffolds as working platforms, it is necessary to continuously advance as the steel formwork moves, and new working scaffolds need to be continuously erected to support the continuously extending bridge deck construction area. The area of the scaffolding foundation to be processed will gradually expand, and a large number of scaffolding are used, which has a great impact on the construction period and cost. At the same time, when carrying out bridge support construction in specific environments such as rivers or narrow spaces, since it is often not possible to erect scaffolding under the bridge, construction workers need to step on the steel formwork for construction. However, long-term construction on the steel formwork easily causes deformation of the steel formwork itself, resulting in a reduction in its service life. Summary of the Utility Model

[0004] The utility model relates to an externally cantilevered walking platform, which can overcome certain or some defects of the prior art.

[0005] An externally cantilevered walking platform, characterized in that: it includes a device main body arranged on both sides of the steel formwork. The device main body includes a pedestrian walking board and a plurality of support crossbars arranged at the side wall of the steel formwork and used to support the pedestrian walking board; the support crossbars are arranged at intervals along the length direction of the steel formwork; a limiting plate is provided at one end of the support crossbar away from the steel formwork, and the limiting plate and the support crossbar together form a support interval for the pedestrian walking board to extend into.

[0006] Through the externally cantilevered walking platform of the utility model, the stable support interval formed by the support crossbar and the limiting plate bears the pedestrian walking board, significantly improving construction safety and efficiency. At the same time, it has high adaptability and convenient installation and maintenance characteristics, and optimizes the high-altitude operation environment.

[0007] Preferably, the support crossbar and the steel formwork are fixedly connected by bolts.

[0008] In the present utility model, the support crossbar and the steel formwork are fixedly connected by bolts. Specifically, a connection method of fixing the bolts to the flange plate can be adopted, realizing the stable combination of the support crossbar and the steel formwork, significantly enhancing the structural stability and construction safety of the walking platform, while improving the convenience, adaptability and overall project quality of installation and maintenance, effectively extending the service life.

[0009] Preferably, inclined support legs are provided below the support crossbar, and both ends of the support legs are fixedly connected to the support crossbar and the steel formwork respectively.

[0010] By adding inclined support legs below the support crossbar in the present utility model, both ends are stably connected to the crossbar and the steel formwork, providing additional support force for the entire walking platform, further enhancing the stability and load-bearing capacity of the platform. This triangular support structure is more stable mechanically and can effectively resist adverse factors such as external loads and wind forces, ensuring the safe operation of construction workers on the platform.

[0011] Preferably, a guardrail is provided at one end of the pedestrian tread board away from the steel formwork, and the included angle between the guardrail and the pedestrian tread board is 90 degrees.

[0012] By adding a guardrail with a 90-degree included angle at one end of the pedestrian tread board away from the steel formwork in the present utility model, further safety protection is provided for construction workers to prevent construction workers from accidentally falling during the operation. Especially in the high-altitude operation environment, this guardrail can effectively block people from approaching the edge, reducing the risk of falling and creating a safer operation environment for construction workers.

[0013] Preferably, the guardrail includes guardrail vertical poles arranged longitudinally and guardrail crossbars arranged transversely; connecting pieces for connecting the guardrail vertical poles and the pedestrian tread board are provided on the tread board, and the shape of the connecting pieces is L-shaped.

[0014] Through the design of the L-shaped connecting pieces in the present utility model, the guardrail vertical poles can be firmly fixed on the pedestrian tread board, reducing potential safety hazards caused by loose connections. At the same time, the L-shaped connecting pieces simplify the installation process of the guardrail, enabling construction workers to quickly and accurately fix the guardrail on the pedestrian tread board.

[0015] Preferably, the connecting piece includes a first connecting plate for connecting the pedestrian tread board and a second connecting plate for connecting the guardrail vertical pole; a first through hole for the bolt to pass through is provided at the first connecting plate; a second through hole for the bolt to pass through is provided at the second connecting plate; a first threaded hole corresponding to the first through hole is provided on the pedestrian tread board, and a second threaded hole corresponding to the second through hole is provided at the lower end of the guardrail vertical pole.

[0016] Through the structure of the refined connecting piece and the fastening method using bolt connection in the present utility model, the connection stability is significantly enhanced, the installation efficiency is improved, maintenance and replacement are facilitated, and the adaptability is enhanced.

[0017] Preferably, there are 2 extension plates perpendicular to the second connecting plate provided at the second connecting plate; the 2 extension plates and the second connecting plate together form a limiting interval for the guardrail vertical pole to extend into.

[0025] Embodiment 1

[0026] As Figures 1-5 shown, an outer cantilever walking platform includes a device main body 200 arranged on both sides of the steel formwork 100. The device main body 200 includes a pedestrian walking board 210 and a plurality of support crossbars 220 arranged on the side wall of the steel formwork 100 and used for supporting the pedestrian walking board 210; the support crossbars 220 are arranged at intervals along the length direction of the steel formwork 100; a limiting plate 230 is provided at one end of the support crossbar 220 away from the steel formwork 100, and the limiting plate 230 and the support crossbar 220 together form a support interval for the pedestrian walking board 210 to extend into.

[0027] With the externally cantilevered walking platform in this embodiment, during the construction process, the main body 200 of the device is fixed on both sides of the steel formwork 100. The supporting crossbars 220 are spaced apart along the length direction of the formwork for support, and are equipped with limit plates 230 to form a stable support area. The anti-slip pedestrian stepping plates 210 are laid, jointly constituting a safe and efficient high-altitude working platform. At the same time, it provides a stable and spacious working space for the construction workers, eliminating the need for frequent erection and dismantling of temporary scaffolding, reducing non-working time, enabling the construction workers to focus more on the work tasks, thus accelerating the construction progress and improving the overall construction efficiency.

[0028] In this embodiment, the supporting crossbar 220 and the steel formwork 100 are fixedly connected by bolts.

[0029] In this embodiment, the supporting crossbar 220 and the steel formwork 100 are fixedly connected by bolts. Specifically, the bolts can be fixedly connected to the flange plate. The bolt and flange plate fixed connection is a mechanical connection method. It combines the fastening force of the bolt and the bearing area of the flange plate to form a firm and reliable connection method. In this connection method, the flange plate is usually welded or fixed to the components to be connected (such as the supporting crossbar and the steel formwork), and then two or more components are tightly connected together by bolts and nuts. At the same time, as a high-strength, high-reliability and easy-to-maintain connection method, the bolt and flange plate fixed connection has broad application prospects in engineering fields such as construction and bridges.

[0030] In this embodiment, inclined support legs 240 are provided below the supporting crossbar 220. Both ends of the support legs 240 are fixedly connected to the supporting crossbar 220 and the steel formwork 100 respectively.

[0031] In this embodiment, by adding inclined support legs 240 below the supporting crossbar 220, these support legs 240 stably connect the supporting crossbar 220 and the steel formwork 100, forming a stable triangular support structure, significantly enhancing the stability and load-bearing capacity of the platform, and ensuring the safety and efficiency of high-altitude operations. The support legs 240 are made of high-strength, corrosion-resistant steel or alloy materials, and are tightly fixed to the supporting crossbar 220 and the steel formwork 100 by reliable means such as bolts to form a stable structure. During installation, strictly follow the design requirements to ensure tight connection without gaps, and perform anti-corrosion treatment to improve durability and maintenance convenience.

[0032] In this embodiment, a guardrail 250 is provided at one end of the pedestrian stepping plate 210 away from the steel formwork 100. The included angle between the guardrail 250 and the pedestrian stepping plate 210 is 90 degrees.

[0033] By arranging the guardrail 250 at one end of the pedestrian tread 210 away from the steel formwork 100 in this embodiment, the risk of accidental fall of operators can be effectively prevented, providing a solid safety line for high-altitude operations. The guardrail 250 is usually made of anti-slip, wear-resistant and corrosion-resistant materials (such as galvanized steel pipes, stainless steel, etc.) to ensure its good durability and corrosion resistance.

[0034] In this embodiment, the guardrail 250 includes guardrail vertical poles 251 arranged longitudinally and guardrail horizontal bars 252 arranged transversely; there is a connecting piece 260 on the pedestrian tread 210 for connecting the guardrail vertical poles 251 and the pedestrian tread 210, and the shape of the connecting piece 260 is L-shaped.

[0035] The guardrail vertical poles 251 and the transverse guardrail horizontal bars 252 in this embodiment form a solid mesh structure, and are firmly fixed on the pedestrian tread 210 by using the L-shaped connecting piece 260, improving the overall stability and load-bearing capacity of the guardrail 250, and also ensuring the comprehensiveness and effectiveness of the protection range, providing a more reliable safety guarantee for high-altitude operations. The L-shaped connecting piece 260 is firmly installed at an appropriate position on the pedestrian tread 210, and its shape and size are precisely calculated to ensure that it can closely cooperate with the guardrail vertical poles 251 and provide sufficient strength and stability.

[0036] In this embodiment, the connecting piece 260 includes a first connecting plate 261 for connecting the pedestrian tread 210, and a second connecting plate 262 for connecting the guardrail vertical poles 251; a first through hole 263 for the bolt to pass through is provided at the first connecting plate 261; a second through hole 264 for the bolt to pass through is provided at the second connecting plate 262; a first threaded hole 211 corresponding to the first through hole 263 is provided at the pedestrian tread 210, and a second threaded hole 253 corresponding to the second through hole 264 is provided at the lower end of the guardrail vertical pole 251.

[0037] The connecting piece 260 in this embodiment is composed of a first connecting plate 261 and a second connecting plate 262, which are respectively connected to the pedestrian tread 210 and the guardrail vertical poles 251. The first connecting plate 261 and the second connecting plate 262 are integrally formed. The first connecting plate 261 matches the pedestrian tread 210, and is provided with precisely corresponding first through holes 263 and threaded holes to ensure a firm connection; the second connecting plate 262 matches the guardrail vertical poles 251, and is provided with precisely corresponding second through holes 264 and threaded holes to achieve a tight connection with the vertical poles. The two together form a stable connection system. Through the tight cooperation of the bolts and the threaded holes, it is ensured that the guardrail vertical poles 251 are stable on the pedestrian tread 210, guaranteeing the stability of the overall structure. Its installation is simple and fast, easy to maintain, and has strong adaptability, and can be flexibly applied to components of different sizes and shapes to meet the diverse engineering requirements.

[0038] In this embodiment, there are two extension plates 265 perpendicular to the second connection plate 262 at the second connection plate 262; the two extension plates 265 and the second connection plate 262 together form a limiting interval for the guardrail vertical pole 251 to extend into.

[0039] Through the two extension plates 265 provided at the second connection plate 262 in this embodiment and the limiting interval formed by them and the second connection plate 262, the main function of the extension plates 265 is to provide additional support and positioning to ensure that the guardrail vertical pole 251 can accurately enter and be fixed in the predetermined position during installation. At the same time, when the two extension plates 265 are respectively perpendicular to the second connection plate 262, a U-shaped limiting interval is formed between them and the second connection plate 262. The size and shape of this interval are precisely designed according to the cross-sectional size and shape of the guardrail vertical pole 251 to ensure that the vertical pole can be tightly and stably embedded therein, thereby realizing the effective positioning and restriction of the guardrail vertical pole 251, enhancing the stability and safety of the structure, and improving the installation convenience.
