Description

Technical Field

[0001] This invention relates to the field of protective shed technology, and in particular to an attached lifting protective shed. Background Technology

[0002] When performing overlapping operations, safety protective canopies should be set up within the fall radius for isolation measures. Safety protective canopies are protective structures erected to prevent injury to personnel or damage to materials and equipment from falling objects during overlapping operations at heights. When constructing high-rise buildings, safety protective canopies with a width greater than 5 meters should be erected around the perimeter of the building at vertical intervals not exceeding 30 meters.

[0003] Safety protection sheds are typically erected using coupler-type steel pipe scaffolding. First, steel sections are suspended around the perimeter of the building floors, and the suspended ends are fixed to the upper structure with diagonal steel wire ropes. Then, horizontal steel pipe frames are erected on the steel sections, and vertical steel pipe frames are erected at the outer ends. Bamboo boards are then tied to the horizontal steel pipe frames, and plywood is tied to the vertical steel pipe frames for enclosure.

[0004] Safety sheds constructed using coupler-type steel pipe scaffolding require erection every 30 meters, consuming significant amounts of materials and labor. The erection and dismantling of these sheds take place at heights, posing a high risk of falls and falling objects; repeated erection and dismantling operations further increase the probability of accidents. Summary of the Invention

[0005] To address the aforementioned problems, the purpose of this invention is to provide an easily assembled and disassembled attached lifting protective canopy that saves on material usage, labor, and costs, while also facilitating material selection, reducing safety risks associated with working at heights, and increasing the effectiveness of horizontal protection.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an attached lifting protective shed, comprising an attachment support, a vertical main frame, a frame structure, a protective shed, diagonal braces, operating channels, and a lifting mechanism. The vertical main frame is fixed to the building structure via the attachment support. The frame structure is installed between two adjacent vertical main frames. Multiple operating channels are provided along the vertical direction of the vertical main frame. The inner end of the protective shed is fixedly connected to the lower part of the vertical main frame. The outer end of the protective shed is fixedly connected to the middle node of the vertical main frame via the diagonal braces. The middle part of the lifting mechanism is fixedly connected to the building structure, and its upper and lower parts are fixedly connected to the upper and lower parts of the vertical main frame, respectively.

[0007] The vertical main frame consists of guide rails, main uprights, and rigid supports. Each machine position is equipped with one vertical main frame.

[0008] The frame structure consists of secondary uprights, horizontal support trusses, patterned treads, and rigid supports. Patterned treads are installed between two vertical main frames, and horizontal support trusses are installed on the outer row to connect the vertical main frames and secondary frames into a whole.

[0009] The protective canopy consists of a cantilever truss, connecting angle steel, upper support beam, support beam fixing components, protective netting, lower support beam, protective panels, railings, and balustrades. The cantilever truss is fixedly connected to the lower part of the vertical main frame or sub-frame via connecting angle steel. The lower support beam is fixed to the lower chord of the cantilever truss via support beam fixing components, and a protective panel is installed on the lower support beam to form a lower hard plane protection. The upper support beam is fixed to the upper chord of the cantilever truss via support beam fixing components, and a planar protective netting is installed on the upper support beam to form an upper soft plane protection. Railings are installed on the outermost upper and lower support beams, and balustrades are installed on the railings to form the outer facade protection.

[0010] In the above technical solution, the cantilever truss is fixedly connected by chords and web members. The chords are provided with bolt holes, and the upper support beam and the lower support beam are both rectangular tubes with bolt holes on them.

[0011] In the above technical solution, the supporting beam fixing component is welded from positioning angle steel and positioning steel plate. The positioning angle steel is provided with slots, and the positioning steel plate is drilled with bolt holes.

[0012] In the above technical solution, the diagonal tie rod is threadedly connected to both ends of the nut weldment by a lead screw weldment; the lead screw weldment is welded from a lead screw connecting plate and a lead screw, and bolt holes are drilled on the lead screw connecting plate; the nut weldment is welded from a left-hand nut, a steel pipe, an adjusting handle and a right-hand nut.

[0013] In the above technical solution, a diagonal tie rod is installed at each cantilever truss.

[0014] In the above technical solution, the operating channel consists of patterned pedals, vertical protective netting, protective netting connectors, and a flip-up plate.

[0015] In the above technical solution, the lifting mechanism consists of an upper bracket, a hanging bracket, a lifting power device, a load sensor, and a lower bracket.

[0016] In summary, the advantages of the technical solution of this invention compared with traditional technical means are as follows: the attached lifting protective shed of this invention can be erected in one go and can be lifted upward with the building structure through its own lifting equipment. Compared with the safety protective shed erected by fastener steel pipe scaffolding, it reduces the number of erections, saves material consumption, saves labor, and reduces the safety risks of high-altitude operations.

[0017] Some components of the attached lifting protective shed utilize components from attached lifting scaffolding, achieving interchangeability of components across different products, improving component utilization, saving costs, and facilitating material selection. The double-layer protective structure of the upper flat protective net and the lower protective plate increases the effectiveness of horizontal protection; the protective plate and flat protective net are made of standardized steel materials, which are fireproof and aesthetically pleasing.

[0018] The protective canopy is supported on a vertical main frame or secondary frame, and the main and secondary frames are reinforced by horizontal support trusses, resulting in good overall stability. The horizontal support trusses also serve as guardrails and scissor braces. The design of the operating passage facilitates the installation and removal of the attachment supports, and the cantilevered platform helps prevent falling objects and falls from heights during vertical cross-operations, greatly improving safety.

[0019] The cantilever truss serves as the main supporting beam of the protective canopy, capable of withstanding the upward tilting effect of wind loads on the canopy. The upper and lower support beams are fixed to the upper and lower chords of the cantilever truss, increasing lateral stiffness. The diagonal tie rods are rigid members, capable of withstanding both the tensile force generated by the protective canopy and the compressive force generated by wind loads, greatly improving safety performance during use.
