Description

Technical Field

[0001] The utility model belongs to the field of construction protection scaffolds, in particular to a unit-combined adjustable assembled steel protection hanging scaffold. Background Art

[0002] In modern high-rise building construction, since the construction progress of the main structure leads that of the secondary structure, especially in the case of the internal core tube and the steel structure outer frame, after the attached lifting scaffold climbs with the main structure, the secondary structure is exposed without protection. From the perspective of economy or safety, during the construction of the secondary structure at the edge of the steel structure outer frame, generally, the attached lifting scaffold or the cantilevered outer scaffold will not be selected as the external facade protection measure again. After wearing safety belts, workers will carry out the operations of edge masonry and edge construction column pouring without any external protection, posing great risks of personnel falling from height and falling objects hitting people.

[0003] In view of the above problems, the patent publication number CN218479511U discloses an existing hanging scaffold system. Due to the overall welded fixed-size design of the main protection frame, the following technical problems still exist in actual use:

[0004] I. Inconvenient turnover:

[0005] The main protection frame is designed with overall or modular welded fixed connections. The overall size is large. After all rigid components are fixedly connected by full welding, the frame has strong integrity but cannot be disassembled, resulting in that some hanging scaffolds with larger designed widths cannot be transported with vehicles for turnover. The vehicle transportation turnover efficiency is low and the transportation cost is relatively high.

[0006] II. The height of the system is non-adjustable and the adaptability to floor heights is poor:

[0007] The main protection frame is fixedly connected by welding and its height is non-adjustable. It can only adapt to one floor height and its application range is limited to the standard floors within the project. It does not meet the conditions for non-standard floors or for being reused in other projects and cannot adapt to the working conditions under different floor heights of different projects, with low adaptability.

[0008] III. The wall nodes vary greatly and the structural adaptability is poor:

[0009] The connecting hanging seats of the hanging scaffold are fixedly connected by welding. The slot sizes of the connecting hanging seats need to be standardized according to the sizes of the standard floor counter-camber nodes. The designed sizes only target the single wall nodes of the standard floors and cannot be turned over and applied to the edge structures with non-standard sizes, nor can they be adjusted adaptively. Content of the Utility Model

[0010] The purpose of the present utility model is to provide a unit - combined adjustable prefabricated steel protection hanging rack, aiming to solve the technical problems existing in the existing hanging rack system, where the protection main frame is designed with integral welding and fixed dimensions, resulting in inconvenient turnover, poor floor - height adaptability, and poor structural adaptability in actual use.

[0030] Compared with the prior art, the utility model has the following characteristics and beneficial effects:

[0031] The utility model makes an overall improvement to the existing hanging rack system. Through the unit combination adjustable assembly design, the hanging rack system is basically divided into four units, namely the vertical adjusting core keel, the upper hanging seat unit, the lower hanging seat unit and the horizontal protective rib unit. A middle platform unit can also be added to become five units. Each unit fitting is welded by section steel, with high safety and reliability. Each unit is sleeved on the vertically adjustable core keel, and the adjustable connection is realized through the connection holes opened on the unit passing through the connecting bolts, so that the vertical position of each unit on the vertical adjusting core keel is adjustable. The vertical adjusting core keel is inserted as a longitudinal adjusting track, and each unit component is nested outside the keel. According to the floor height situation, it is fixed by bolt perforation at the appropriate elevation hole position, and the height of the rack body is freely adjusted according to different use conditions to ensure adaptation to the floor height and can be used on non-standard floors and refuge floors.

[0032] The detachable sleeve assembly design of each unit of the utility model and the vertical adjusting core keel enables the main frame of the hanging rack to be disassembled according to the fittings after use. The size of a single unit component is small, which is convenient for classification, coding and packing, improves the turnover efficiency, and ensures that it can be disassembled into components and packed and transported with the vehicle to other projects for use after demolition. The main keel and the components are drilled according to the modulus, with a standardized design, which improves the processing efficiency. At the same time, the assembly method is simple, and bolt perforation connections are used between the components, which is convenient for workers to operate.

[0033] The upper hanging seat unit and the lower hanging seat unit of the utility model are also provided with edge adjustment parts. The edge adjustment parts are also sleeved with the hanging seat units, and the adjustable connection is realized through the connection holes opened on the rod members passing through the connecting bolts, so as to adjust the distance between the edge adjustment parts and the hanging seat units. The edge adjustment parts are clamped inside the convex body of the edge structure, and the opening size of the clamping groove is adjustable, which is suitable for structural counter-curbs of various structural forms and sizes, such as counter-curbs, inverted beams, parapets or structural inward contractions, etc., to ensure the adaptable use of different edge structures when the wall node changes.

[0034] The horizontal protection rib unit of the present utility model can also be sleeved at the corresponding position of the vertical adjustment core keel as required, with flexible adaptability.

[0035] The present utility model is applicable to the construction of building masonry exterior walls lacking edge protection and having a counter-camber at the structural edge. It ensures that the external protection structure still exists during the exterior wall construction operation, with high safety, and avoids potential safety hazards due to lack of protection. The present utility model can be adjusted according to the building floor height and counter-camber size, with high universality, applicable to various styles of edge parts, and can be disassembled according to components for turnover, transportation and use, with good economy, simple processing, and flexible installation and disassembly.

[0093] The bracket can be determined according to the design size, and different specifications of steel pipes, square steels, channel steels, angle steels, etc. can be used as raw materials to meet the force requirements.

[0094] The bracket should ensure that there are at least two supports on each layer, and the distance between adjacent supports can be determined based on load calculation.

[0095] The safety net can be made of stamped steel plate mesh or close-mesh safety net. Since the lifting process involves large shaking, firm and reliable fixing measures must be taken when using stamped steel plate mesh.

[0096] The drilling spacing can be determined based on actual usage requirements, while ensuring the bearing capacity of the vertical main keel.
