Description

Technical Field

[0001] This utility model relates to the field of prefabricated building construction technology, and in particular to an adjustable prefabricated rectangular steel column high-altitude construction platform. Background Technology

[0002] Currently, prefabricated construction has become a development trend and is developing rapidly. Prefabricated steel structures have high construction efficiency, low labor intensity, and are environmentally friendly. The construction platform in prefabricated steel structure buildings is an important component. It is processed in the factory and assembled on site. However, in actual engineering construction, there are problems with size adjustment and transportation efficiency. Cutting and welding are required, which involves a large workload and requires additional construction resources. For the problem of high-altitude welding platforms for steel columns, it is particularly important to adopt a simple, efficient, and reusable platform system. It can be seen that traditional high-altitude welding construction platforms are not only inefficient but also costly. Therefore, we have introduced an adjustable prefabricated rectangular steel column high-altitude construction platform. Utility Model Content

[0003] The main purpose of this utility model is to provide an adjustable prefabricated rectangular steel column high-altitude construction platform, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An adjustable prefabricated rectangular steel column high-altitude construction platform includes a steel column body, two angle steels are fixedly connected to the upper front end of the steel column body, a construction ladder is fixedly connected to the front end of the steel column body by the two angle steels and bolts, and a construction platform is fixedly connected to the upper outer surface of the steel column body by bolts.

[0006] The construction platform includes four square tube support unit frames. Several perforated square tube sleeves are connected together among the four square tube support unit frames. Guardrails are fixedly connected to the upper ends of the four square tube support unit frames and the upper ends of the perforated square tube sleeves through square tubes and bolts. Two guardrail steel wire ropes are fixedly connected together among the guardrails. The platform operation area is fixedly connected to the upper ends of the four square tube support unit frames and the upper ends of the perforated square tube sleeves.

[0007] Preferably, the inner surfaces of several of the perforated square tube sleeves are fixedly connected to the outer surface of the steel column body by bolts.

[0008] By adopting the above technical solution, construction workers only need to use conventional tools (such as wrenches) to connect the perforated square tube sleeve to the steel column body at the construction site.

[0009] Preferably, the height of each of the guardrails is set to 1.2m.

[0010] By adopting the above technical solution, in the field of building construction, the standard height of 1.2m guardrail is determined based on a large amount of safety research and practical experience. This height can effectively prevent construction workers from accidentally slipping, tripping, or being hit by external forces and falling over the guardrail when working at height. It provides sufficient protection height for construction workers, meets the relevant safety specifications, and thus protects the lives of construction workers.

[0011] Preferably, the platform operating area is provided with a steel grating or patterned steel plate.

[0012] By adopting the above technical solution: the surface of steel grating or patterned steel plate has a certain texture and roughness. On high-altitude construction platforms, construction workers need to frequently walk around the platform operation area, carry tools and materials, etc. This surface characteristic can provide a good anti-slip effect. Even in complex construction environments such as wet, oily or dusty conditions, it can effectively reduce the risk of construction workers slipping and ensure that construction workers can work safely on the platform.

[0013] Preferably, several of the guardrails are connected by two guardrail wire ropes.

[0014] By adopting the above technical solution, several guardrails are connected together by guardrail wire ropes to form an integrated protective structure. Alternatively, the guardrail wire ropes can be replaced with color steel plates for enclosure as needed during construction.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, the construction ladder is connected to the angle steel by bolts, the perforated square tube sleeve is connected to the steel column body and the square tube support unit frame by bolts, and the guardrail is fixed by square tube and bolts. All of these are bolted connections. This connection method makes the entire construction platform easy to assemble and disassemble. After a project is completed, the platform can be easily disassembled into various parts for easy transportation to other projects for reuse. This greatly improves the recyclability of the platform and reduces project costs.

[0017] 2. In this utility model, since it can be easily disassembled into multiple parts, each part can be compactly stacked during transportation, which improves transportation efficiency. Moreover, during on-site assembly, the connection method of each part is simple and clear. The four square tube support unit frames are connected by connecting perforated square tube sleeves, and then the guardrail and platform operation area are connected by bolts. There is no need for complicated cutting and welding processes, which reduces the workload of on-site installation, thereby shortening the construction cycle and reducing the construction difficulty.

[0028] An adjustable prefabricated rectangular steel column high-altitude construction platform includes a steel column body 1, two angle steels 2 are fixedly connected to the upper front end of the steel column body 1, a construction ladder 3 is fixedly connected to the front end of the steel column body 1 through the two angle steels 2 and bolts, and a construction platform 4 is fixedly connected to the upper outer surface of the steel column body 1 through bolts.

[0029] In this embodiment, the construction platform 4 includes four square tube support unit frames 41. Several perforated square tube sleeves 42 are connected to each other across the four square tube support unit frames 41. Guardrails 43 are fixedly connected to the upper ends of the four square tube support unit frames 41 and the upper ends of the several perforated square tube sleeves 42 via square tubes and bolts. Two guardrail steel cables 44 are fixedly connected to each other across the guardrails 43. A platform operating area 45 is fixedly connected to the upper ends of the four square tube support unit frames 41 and the several perforated square tube sleeves 42. The inner surfaces of the several perforated square tube sleeves 42 are fixedly connected to the outer surface of the steel column body 1 via bolts. The height of each guardrail 43 is set to 1.2m. The platform operating area 45 is constructed of laid steel grating or patterned steel plate. The guardrails 43 are connected by two guardrail steel cables 44.

[0030] It should be noted that this utility model is an adjustable prefabricated rectangular steel column high-altitude construction platform. During use, firstly, align the construction ladder 3 with the angle steel 2, and use bolts to fix the construction ladder 3 to the angle steel 2, thus firmly installing the construction ladder 3 onto the steel column body 1. Next, take out four square tube support unit frames 41 and arrange them around the upper outer surface of the steel column body 1. These four square tube support unit frames 41 are the basic support structure of the construction platform 4. Then, take several perforated square tube sleeves 42 and sequentially connect these perforated square tube sleeves 42 to the four... Between the square tube support unit frames 41, bolts are used to fix the inner sides of several perforated square tube sleeves 42 to the outer surface of the steel column body 1. In this way, the perforated square tube sleeves 42 not only connect the square tube support unit frames 41, but also firmly connect to the steel column body 1, enhancing the structural stability of the entire construction platform 4. The guardrails 43 are then taken out, and the lower ends of the guardrails 43 are fixedly sleeved onto the upper ends of the four square tube support unit frames 41 and the upper ends of several perforated square tube sleeves 42 using square tubes and bolts. The height of all guardrails 43 is set to 1.2m, install the guardrails 43 sequentially according to the perimeter shape of the construction platform 4, ensuring the guardrails 43 are firmly installed. During the installation of the guardrails 43, connect the guardrail wire ropes 44 to the adjacent guardrails 43 to form a stable protective structure between the guardrails 43. The platform operation area 45 is fixedly connected to the upper ends of the four square tube support unit frames 41 and several perforated square tube sleeves 42. According to actual needs, the platform operation area 45 can be set as a laid steel grating or patterned steel plate. Lay the steel grating or patterned steel plate smoothly and fix it on the above structure to form a flat area for construction personnel to operate. Then, the construction personnel climb to the construction platform 4 through the construction ladder 3 installed on the steel column body 1. After the construction personnel reach the platform operation area 45 of the construction platform 4, they can carry out high-altitude operations, such as steel structure installation and welding, on this stable and safe operating plane. During the operation, the surrounding guardrails 43 and guardrail wire ropes 44 form a stable protective structure. The protective structure effectively prevents construction workers from accidentally falling and ensures their safety. When dismantling is required after construction, remove the steel grating or checkered steel plate from the platform operating area 45. If it is a steel grating, carefully remove it from the fixed structure. If it is a checkered steel plate, unscrew the fixing bolts and other connectors, remove the checkered steel plate, and disconnect the connection between the protective steel wire rope 44 and the guardrail 43. Then, use tools to unscrew the guardrail 43 from the square tube support unit frame 41 and the perforated square tube sleeve 42. Remove the bolts connecting the upper ends of the guardrail 43 one by one. Use tools to unscrew the bolts fixing the perforated square tube sleeve 42 to the outer surface of the steel column body 1. Then, pull the perforated square tube sleeve 42 out from between the square tube support unit frames 41. Finally, unscrew the connecting bolts between the square tube support unit frames 41 to remove the four square tube support unit frames 41 from around the steel column body 1. Use tools to unscrew the bolts connecting the construction ladder 3 to the angle steel 2 and remove the construction ladder 3 from the steel column body 1.
