Description

Technical Field

[0001] This application belongs to the field of engineering protection technology, and specifically relates to a portable fireproof and insulating shed. Background Technology

[0002] In places such as construction sites, industrial production sites, and power facility maintenance sites, it is usually necessary to build protective sheds to protect facilities, equipment, personnel, and the surrounding environment from hazards such as fire, falling objects, and electric shock.

[0003] However, traditional protective sheds are mostly fixed structures, unable to be flexibly moved according to the work location, making them extremely inconvenient to use. Furthermore, existing protective sheds are often functionally limited, typically only providing either fire protection or insulation, making it difficult to simultaneously meet multiple protection needs. For example, in rail transit reconstruction or power construction, fixed protective sheds cannot be adjusted with changes in the construction location, requiring frequent disassembly and reassembly, which not only consumes a significant amount of manpower, resources, and time, but may also damage existing facilities. While some protective sheds are movable, their fire resistance and insulation performance are insufficient, failing to effectively isolate high-voltage current or prevent the spread of flames, posing significant safety hazards.

[0004] Therefore, there is an urgent need for a multifunctional protective shed that combines mobility, fire resistance, and insulation to improve operational safety and flexibility. Utility Model Content

[0005] The purpose of this application is to provide a movable fireproof and insulated shed. This addresses the problems of existing protective sheds being immovable and lacking sufficient fireproof and insulation performance, as mentioned in the background section, thereby improving operational safety and flexibility.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A portable fireproof and insulated shed is provided, comprising a shed body and two parallel tracks laid on the ground;

[0008] The bottom sides of the shed are mounted on a track via rollers and can move along the track.

[0009] The cross-section of the shed, from the outside to the inside, includes a fireproof layer, a protective layer, a steel frame structure, and an insulation layer, wherein;

[0010] The fireproof layer is a fireproof cloth that is fully covered on the top and sides of the shed.

[0011] The protective layer consists of protective steel plates that are fully covered on the top and sides of the shed and are fixedly connected to the frame steel structure.

[0012] The skeleton steel structure is a rectangular steel tube frame used to support the fireproof layer, protective layer and insulation layer;

[0013] The insulation layer is an insulating rubber pad suspended inside the frame steel structure.

[0014] In one possible implementation, the fireproof layer is made of fireproof cloth with a thickness of 0.5-1.5 mm and coated with a fire-retardant coating.

[0015] In one possible implementation, the protective layer is made of galvanized steel sheet with a thickness of 1.5-3mm, and the outer side of the galvanized steel sheet is provided with raised reinforcing ribs.

[0016] In one possible implementation, the insulating layer is an insulating rubber pad with a thickness of 5-10 mm.

[0017] In one possible implementation, the frame steel structure is welded from rectangular steel tubes with a cross-sectional size of 80mm×60mm×3mm, and the spacing between the top frames is 500-800mm.

[0018] In one possible implementation, the track uses national standard steel rails.

[0019] In one possible implementation, the rollers at the bottom of both sides of the shed are cast steel rollers, and the roller surfaces are provided with anti-slip textures.

[0020] In one possible implementation, fireproof roller shutters are provided at the openings at both ends of the shed, and sealing strips are provided between the roller shutters and the frame steel structure.

[0021] In one possible implementation, the insulating layer is an electrostatic insulating board.

[0022] In one possible implementation, the top and sides of the shed are also provided with grounding devices, which include grounding flat steel connected to the frame steel structure.

[0023] Compared with the prior art, this application has the following beneficial effects:

[0024] This application provides a portable fireproof and insulated shed. This portable fireproof and insulated shed achieves efficient protection and flexible operation through a multi-layered structural design. The fireproof cloth, steel plate, and insulating rubber pads on its top and sides constitute a fireproof layer, a protective layer, and an insulating layer, respectively. These effectively prevent spark ignition, resist impact from objects, and isolate high-voltage current, meeting the multiple needs of fire prevention, protection, and insulation in engineering scenarios. The rollers and tracks at the bottom allow the shed to move quickly along the tracks without frequent disassembly and reassembly, significantly improving the convenience of adjusting the work position and reducing manpower and material consumption. The steel frame structure, as the main load-bearing frame, ensures the rigidity and stability of the shed during hoisting and movement through reasonable material selection and structural design, providing solid support for the reliable realization of the overall protective function.

[0025] In one possible implementation, fireproof cloth of a specific thickness is used and coated with a flame-retardant coating, which greatly improves the fire resistance limit and can effectively prevent the penetration of gas cutting welding sparks; the full-height side coverage design eliminates fire blind spots and forms a three-dimensional fire barrier, which is especially suitable for construction environments with frequent hot work operations and reduces the probability of fire accidents.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] like Figure 1 and Figure 2 As shown, this application discloses a movable fireproof and insulating shed, which may include a shed body 1 and two parallel tracks 2 laid on the ground.

[0038] Track 2 can be a national standard steel track with a gauge of 18.26m.

[0039] The bottom sides of the canopy 1 are mounted on the track 2 via rollers 6 and can move along the track 2. The bottom sides of the canopy 1 are mounted on the track 2 via cast steel rollers 6 with a diameter of 250mm. The rollers 6 are rigidly connected to the frame steel structure via bearings.

[0040] The cross-section of the shed 1, from the outside to the inside, includes a fireproof layer 3, a protective layer 4, a steel frame structure, and an insulation layer 5, wherein...

[0041] The fireproof layer 3 is a fireproof cloth that is fully covered on the top and sides of the shed body 1.

[0042] Optionally, the fireproof cloth can be made of 0.35mm fiberglass fireproof cloth, with a 5mm thick Q235B galvanized steel plate in the middle and a 5mm insulating rubber pad on the inner side.

[0043] The protective layer 4 is a protective steel plate that is fully covered on the top and sides of the shed body 1 and is fixedly connected to the frame steel structure.

[0044] The steel frame structure is a rectangular steel tube frame with a top spacing of 5m. The secondary beams are made of 120×120×4mm rectangular tubes and can be used to support the fireproof layer 3, the protective layer 4 and the insulation layer 5. The steel frame structure is shown in the figure.

[0045] In this embodiment, the movable fireproof and insulated shed achieves efficient protection and flexible operation through a multi-layered structural design. The fireproof cloth, steel plate, and insulating rubber pads on its top and sides constitute the fireproof layer 3, protective layer 4, and insulating layer 5, respectively, which can effectively prevent spark ignition, resist impact from objects, and isolate high-voltage current, meeting the multiple requirements of fire prevention, protection, and insulation in engineering scenarios. The rollers 6 at the bottom cooperate with the track 2, allowing the shed 1 to move quickly along the track 2 without frequent disassembly and assembly, significantly improving the convenience of adjusting the working position and reducing the consumption of manpower and material resources. The steel frame structure serves as the main load-bearing frame, and through reasonable material selection and structural design, it ensures the rigidity and stability of the shed 1 during hoisting and movement, providing solid support for the reliable realization of the overall protection function.

[0046] In one possible embodiment, the fireproof layer 3 may be a fireproof cloth with a thickness of 0.5-1.5mm, and the surface is coated with a fire-retardant coating.

[0047] Specifically, the fireproof layer 3 uses 1mm thick silicone rubber fireproof cloth, coated with an aluminum hydroxide flame-retardant coating, with a fire resistance limit of 1.5 hours. In addition to covering the entire top, the fireproof cloth extends to the ground on both sides and is fixed to the frame steel structure with stainless steel clamps.

[0048] In this embodiment, by coating the fireproof cloth with a flame-retardant coating and combining it with the material's own fire-resistant properties, it can effectively block the penetration of sparks generated by external gas cutting and welding operations, thus significantly reducing the risk of fire. At the same time, the fireproof cloth is fully covered on the top and also covers the sides to the full height, completely eliminating fire blind spots on the top and sides, forming a fire protection system without dead angles, and comprehensively improving the overall fire safety.

[0049] In one possible embodiment, the protective layer 4 is made of galvanized steel sheet with a thickness of 1.5-3mm, and the outer side of the galvanized steel sheet is provided with raised reinforcing ribs.

[0050] The protective layer 4 is made of 2mm thick Q235B galvanized steel sheet, coated with anti-rust paint, and has "U"-shaped reinforcing ribs welded at 500mm intervals on the outside of the steel sheet. The top steel sheet is fully covered, and the side steel sheets extend downwards from the top to a distance of 61.2m from the roller.

[0051] In this embodiment, fireproof cloth of a specific thickness is used and coated with a flame-retardant coating, which greatly improves the fire resistance limit and can effectively prevent gas cutting welding sparks from penetrating; the full-height side coverage design eliminates fire blind spots and forms a three-dimensional fire barrier, which is especially suitable for construction environments with frequent hot work operations and reduces the probability of fire accidents.

[0052] In one possible embodiment, the insulating layer 5 is an insulating rubber pad with a thickness of 5-10 mm.

[0053] Insulation layer 5 consists of 8mm thick EPDM insulating rubber pads suspended inside the frame steel structure by copper bolts. The edges of the rubber pads overlap by 100mm and are sealed with conductive adhesive.

[0054] In this embodiment, the galvanized steel plate combined with the reinforcing rib structure significantly enhances the impact resistance and prevents sharp objects from penetrating the fireproof cloth and damaging the facilities below; the rust prevention treatment of the steel plate extends its service life, and the design extending to the top of the roller 6 on the side strengthens the bottom protection and is suitable for operation scenarios with a high risk of falling objects from heights.

[0055] In one possible embodiment, the steel frame structure is welded from rectangular steel pipes with a cross-sectional dimension of 80mm×60mm×3mm, and the spacing between the top frames is 500-800mm.

[0056] The steel frame structure uses rectangular steel tubes, each measuring 100mm × 80mm × 4mm, welded into a grid pattern. The spacing between the top frame members is 600mm, and the spacing between the secondary beams is 1200mm. The steel tubes are hot-dip galvanized with a zinc coating thickness of 85μm.

[0057] In this embodiment, the high resistivity insulating rubber pad, combined with the surface treatment process, can effectively isolate the induction of high voltage current above 10KV, preventing electric shock accidents caused by the energized shed body 1; the edge conductive adhesive sealing design eliminates the risk of leakage, providing reliable electrical safety protection for construction near high voltage lines.

[0058] In one possible embodiment, the rollers 6 at the bottom of both sides of the shed 1 are cast steel rollers 6, and the surface of the rollers 6 is provided with anti-slip texture.

[0059] The roller 6 is made of ZG310-570 cast steel, with a diameter of 250mm and a trapezoidal anti-slip texture on the surface. Roller 6 is connected to the frame steel structure via a 6210 deep groove ball bearing, and the bearing housing is equipped with a grease filling hole.

[0060] In this embodiment, the cast steel roller 6 combines anti-slip texture with a bearing structure to improve load-bearing capacity and smooth movement, adapting to heavy-duty working conditions.

[0061] In one possible embodiment, fireproof roller shutters are provided at the openings at both ends of the shed 1, and sealing strips are provided between the roller shutters and the frame steel structure.

[0062] The shed structure 1 has fire-resistant steel roller shutters installed at both ends, with a fire resistance rating of 1.5 hours. The space between the roller shutters and the steel frame is filled with fire-expanding sealing strips. The roller shutters are equipped with manual opening and closing devices for quick closure in emergencies.

[0063] In this embodiment, the fireproof roller shutter door, in conjunction with the expansion sealing strip, forms an openable and closable fireproof isolation zone at both ends of the canopy 1, effectively preventing the spread of sparks and smoke; the manual opening and closing device ensures rapid response in emergency situations, meets the requirements for fully enclosed protection of the hot work area, and improves emergency safety performance.

[0064] In one possible embodiment, the top and sides of the shed 1 are also provided with grounding devices, which include grounding flat steel connected to the frame steel structure.

[0065] Two grounding devices are installed on the top and sides of the shed 1. They are made of 40mm×4mm hot-dip galvanized flat steel welded to the frame steel structure. The flat steel extends 1.5m below the ground and is connected to a copper grounding electrode. The actual grounding resistance is 2.8Ω.

[0066] In this embodiment, the grounding system composed of hot-dip galvanized flat steel and copper grounding electrode can quickly conduct away static electricity and induced current in the shed body 1, and the grounding resistance can ensure the leakage protection effect; together with the insulation layer 5, it forms double electrical protection, eliminates the risk of electric shock under high voltage environment, and meets the safety specifications requirements of power construction and other scenarios.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
