Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel structure operation and construction platform. Background Technology

[0002] With the rapid pace of urbanization, high-rise residential buildings have sprung up like mushrooms after rain, becoming the main form of housing for many urban residents. However, these early high-rise buildings, after years of use, have gradually revealed a series of problems, leading to an increasing number of maintenance and renovation projects. From the perspective of the buildings themselves, high-rise buildings are characterized by complex structures and great heights, and with increasing years of use, the problem of building aging becomes increasingly prominent. Phenomena such as the detachment of external wall insulation layers and wall cracks leading to water seepage are common in many high-rise buildings over 15 years old. These problems not only seriously affect the quality of life for residents but also pose significant safety hazards.

[0003] Therefore, steel structure operating platforms are needed during the maintenance and renovation of cantilevered roof structures in super high-rise buildings. However, traditional steel structure operating platforms are mostly used in newly built residential projects. With the main construction pre-embedded steel structure nodes, safety is ensured for the fabrication and installation of the steel structure platform by adjusting the construction sequence. But high-rise residential cantilever structures are too large, and maintenance faces challenges such as the lack of pre-embedded points, lack of lower support points, and the inability to arbitrarily damage exterior wall decorations and windows. The site conditions cannot meet the requirements for traditional steel structure platform erection. Therefore, an innovative safe steel platform construction technology for the maintenance and renovation of high-rise residential buildings is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the existing high-rise residential buildings have excessively large cantilever structures, and maintenance faces the challenges of no pre-embedded points, no lower support points, and the inability to arbitrarily damage the exterior wall decorations and windows. The site conditions cannot meet the requirements for the construction of traditional steel structure platforms. Therefore, an innovative construction technology for a safe steel platform for the maintenance and renovation of high-rise residential buildings is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel structure operation and construction platform, including an I-beam main beam, with secondary beams connected to both sides of the I-beam main beam, U-shaped anchor rings provided at the connection between the secondary beams and the I-beam main beam, sockets provided at the front ends of the two sets of secondary beams, steel wire ropes passing through the surface of the secondary beams near the sockets, beams connected to the upper ends of the two sets of steel wire ropes, and multi-layer boards connected to the upper surfaces of the two sets of secondary beams.

[0006] Furthermore, both sides of the multi-layer board are connected to a fastener-type steel pipe operating frame, and the surface of the fastener-type steel pipe operating frame is connected to a crossbar.

[0007] Furthermore, the length of the I-beam main beam is 9m, and the cantilever length is 4.3m, while the length of the secondary beam is 4.5m.

[0008] Furthermore, the beam has a cross-sectional dimension of 200mm × 450mm and a reinforcing bar diameter of 18mm.

[0009] Furthermore, the spacing between the fastener-type steel pipe operating frames is 1000cm.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] In this utility model, the platform is constructed using common I-beams, making the materials easy to select. It can be repeatedly disassembled and reused, reducing construction waste and conforming to the concept of green construction. The platform has high strength and strong load-bearing capacity, and can withstand large construction loads. Combined with protective facilities such as guardrails, kickboards, and safety nets, it forms a closed or semi-closed working space, reducing the probability of safety accidents such as falls from heights and being struck by objects. It is easy to assemble and disassemble, safe and reliable, and improves construction efficiency. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Examples, such as Figure 1 - Figure 3As shown, this utility model provides a steel structure operation and construction platform, including an I-beam main beam 1, with secondary beams 2 connected to both sides of the I-beam main beam 1. U-shaped anchor rings 3 are provided at the connection between the secondary beams 2 and the I-beam main beam 1. Sockets 4 are opened at the front ends of both sets of secondary beams 2. Steel wire ropes 6 are connected through the surface of the secondary beams 2 near the sockets 4. Beam bodies 7 are connected to the upper ends of the two sets of steel wire ropes 6. Multi-layer boards 5 are connected to the upper surfaces of the two sets of secondary beams 2. Coupler-type steel pipe operation frames 8 are connected to both sides of the multi-layer boards 5. Crossbars 9 are connected to the surface of the coupler-type steel pipe operation frames 8. The length of the I-beam main beam 1 is 9m, and the cantilever length is 4.3m. The length of the secondary beams 2 is 4.5m. The cross-sectional dimensions of the beam body 7 are 200mm×450mm, and the diameter of the reinforcing bars is 18mm. The spacing between the coupler-type steel pipe operation frames 8 is 1000cm.

[0019] The implementation achieves the following effect: the main I-beam 1 of the construction platform in this application uses 9-meter-long No. 18 H-shaped I-beams. One end of the main beam extends 4.3 meters out, like a cantilevered balcony. However, for safety, the extended part is firmly anchored to the building structure by a 4.7-meter-long main beam. The secondary beam 2 rests on the main I-beam 1. The connection between the main I-beam 1 and the secondary beam 2 is tightly fixed with U-shaped anchor rings 3 to ensure that it will not loosen. To distribute the weight, two No. 18 steel wire ropes 6 are used as "safety belts". One end of the steel wire rope 6 is fixed to the beam 7 of the building structure above the platform. A hole needs to be drilled in the beam before the rope can pass through. The other end goes around the secondary beam 2. The platform surface is covered with 15mm thick multi-layer board 5 to ensure flatness. Five rows of coupler-type steel pipe operating frames 8 are installed on the secondary beam. 20cm long sockets 4 are welded to the secondary beam 2 according to the positions of the coupler-type steel pipe operating frames 8, facilitating insertion and fixing. Additionally, diagonal braces can be installed on the outside of the frames, connecting to the internal crossbars of the building. Finally, the inside of the frames is completely enclosed with tarpaulin to prevent wind damage and small objects from falling. This application utilizes an I-beam inverted jacking technique and also employs existing structural beams to create a bridge-type steel wire rope anti-tension structure.

[0020] Working principle: The platform in this application is constructed using common I-beams, which are easy to select. It can be repeatedly disassembled and reused, reducing construction waste and conforming to the concept of green construction. The platform has high strength and strong load-bearing capacity, and can withstand large construction loads. With the addition of guardrails, kickboards, safety nets and other protective facilities, it forms a closed or semi-closed working space, reducing the probability of safety accidents such as falls from heights and falling objects. It is easy to assemble and disassemble, safe and reliable, and improves construction efficiency.

[0021] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
