Description

Technical Field

[0001] This utility model relates to the technical field of steel structure bridge installation and construction equipment, and in particular provides a cantilever lateral suspended platform. Background Technology

[0002] During the installation of steel structure bridges, on-site installation and welding of bridge decks are frequently encountered. On-site installation and welding of bridge decks requires construction workers to perform overhead welding at the bottom of the bridge. There are many welding positions and a large number of welds, making the construction difficult and requiring a suspended platform as a working platform.

[0003] Traditional suspended platforms are bulky and cumbersome to assemble and dismantle, impacting construction time and efficiency. Their narrow working platforms restrict worker movement, making them unsuitable for complex tasks. During construction, hand-operated hoists are typically used to suspend the platform, with workers standing inside for overhead welding. This method is inefficient and poses safety risks at multi-site construction sites. The lifting mechanism requires high-safety-factor wire ropes and hoists. Necessary safety protection devices must be incorporated into the design and manufacturing process to ensure worker safety in case of emergencies. Another option is using truck cranes, where workers stand for overhead welding. This method is common at multi-site construction sites, but it is expensive and incurs high construction costs.

[0029] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. The description of exemplary embodiments is merely illustrative and is in no way intended to limit this disclosure or its application or use. This disclosure may be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully express the scope of this disclosure to those skilled in the art.

[0030] like Figures 1 to 5 As shown, this utility model provides a cantilever lateral suspended platform, including a cantilever beam 31, a bottom step 1, and a central front guardrail 21. The cantilever beam 31 includes two beams arranged laterally at intervals, each beam extending horizontally and having its rear end fitted to the shape of the upper surface of the building platform 51. The bottom step 1 is spaced directly below the two cantilever beams 31 and has a groove 11 on its rear side to accommodate building columns 52. The central front guardrail 21 extends vertically and has its lower end connected to the front side of the bottom step 1 and its upper end connected to the front end of the two cantilever beams 31.

[0031] The provided cantilever lateral suspension platform is a low-cost, high-efficiency, and safe cantilever platform. The central front guardrail 21, cantilever beam 31, and bottom step 1 are perpendicular to each other, forming a U-shaped structure to accommodate the front end of the building platform 51. The cantilever beam 31 is suspended from the upper surface of the building. The groove 11 of the bottom step 1 fits into the building column 52. The cantilever beam 31 is fixedly connected to the upper surface of the building platform 51, and / or the bottom step 1 is fixedly connected to the building column. During implementation, the main structure of the suspension platform, including the bottom step 1 and the central front guardrail 21, is made of high-strength steel and undergoes anti-corrosion treatment to ensure its load-bearing capacity and durability. The cantilever beam, as the suspension mechanism, has sufficient rigidity and stability to withstand the entire load of the suspension platform.

[0032] The central front guardrail 21 is perpendicular to the cantilever beam 31 and the bottom step 1, forming a U-shaped structure to accommodate the front end of the building platform. The cantilever beam 31 is suspended on the upper surface of the building. The groove 11 of the bottom step 1 is fitted into the building column 52. The cantilever beam 31 is fixedly connected to the upper surface of the building platform 51, and the bottom step 1 is fixedly connected to the building column 52, thus establishing a stable construction platform for construction personnel and improving construction safety.

[0033] Vertically extending ladders 22 are connected to both sides of the central front guardrail 21. The ladders 22 are perpendicular to the central front guardrail 21, with their upper ends connected to the bottom front end of the cantilever beam 31 and their lower ends connected to the outer side of the bottom step 1. The space enclosed by the inner side of the ladders 22 and the central front guardrail 21 forms a vertical passage from the bottom step 1 to the building platform 51. Furthermore, the width of the bottom step 1 is equal to the distance between the two cantilever beams 31, and a horizontal connecting rod is provided between the middle of the two beams, located at the rear of the ladder 22. The ladders facilitate the movement of construction workers and increase the connection strength between the bottom step 1 and the cantilever beam 31, enabling the bottom step 1 to bear heavier loads.

[0034] The bottom pedal has a square hole behind the groove 11, serving as a vertical passage. A passage cover 12 covers the square hole. One side of the passage cover 12 is hinged to the bottom pedal, and the other side is connected to the bottom pedal via a safety lock pin, allowing it to be opened and closed. When the operator is standing on the bottom pedal for welding, the passage cover 12 is in a locked state, functioning as part of the bottom pedal. When the operator needs to leave or enter the suspended platform, the safety lock pin is released, and the passage cover 12 is flipped upwards to enter or leave the suspended platform through the square hole, eliminating the need to climb in or out through the outer guardrail of the suspended platform, thus improving safety when entering and leaving the suspended platform.

[0035] During implementation, an upward-extending bottom railing 23 is provided around the outer perimeter of the bottom step 1. The front end of the bottom railing 23 is connected to the rear side of the ladder 22, and the rear end extends to both sides of the groove 11. The cantilever beam 31 is connected to an upward-extending top side railing 42, and the middle front railing 21 is connected to an upward-extending top front railing 41. The top side railing 42 and the top front railing 41 are connected to form a railing structure above the front side of the building platform 51. A vertically extending vertical connecting rod 43 is provided in the middle of the top front railing 41, and symmetrically arranged diagonal connecting rods 24 are provided in the middle front railing 21. The upper ends of the two diagonal connecting rods 24 extend to the bottom of the vertical connecting rod 43, and the lower ends extend outward to the bottom outer side of the middle front railing 21. The above-mentioned railings and fences can improve the structural strength of the suspended platform and increase the safety of construction personnel during use.

[0036] Construction personnel conducted a comprehensive analysis of the bridge engineering drawings, taking into account the actual needs of the project, including the fabrication of suspended platform parts, installation of the suspended platform, forward movement of the suspended platform, adjustment and fixation of the suspended platform. This improved the scientific nature of the cantilever suspended platform fabrication, facilitated the rapid fabrication of suspended platform parts in the workshop, and enhanced the overall quality of the cantilever suspended platform fabrication and installation.

[0037] During use, the cantilever beam 31 is connected to the building platform 51 by detachable bolt fasteners, and / or, the cantilever beam 31 is fixed to the upper surface of the building platform 51 by welding. Alternatively, the groove 11 of the bottom pedal 1 can be matched with the cross-sectional dimensions of the building column 52 at the bottom of the building platform 51, the end face of the groove 11 is supported by the front side of the building column 52, and the side is supported by the side of the building column 52. The bottom pedal 1 is connected to the building column 52 by detachable bolt fasteners, and / or, the edge of the groove 11 is fixed to the building column 52 by welding.

[0038] The construction support for the suspended platform is a cantilever beam 31, which does not require the extensive support structure of traditional suspended platforms. Furthermore, it does not require the assistance of crane equipment during construction. The cantilever suspended platform can be quickly moved and fixed by the construction workers through welding. The bottom platform provides a relatively spacious standing space for the construction workers, reducing the difficulty of construction and greatly improving the convenience of construction, while also reducing the demand for construction equipment.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that the cantilever lateral suspended platform of this utility model is not limited to the above-described embodiments, and its construction method is to select a suitable method according to the actual site conditions.
