Description

Technical Field

[0001] The present invention belongs to the technical field of building safety protection, and in particular relates to a rolling shutter door guide rail device compatible with different thicknesses. Background Art

[0002] With the development of the times and the rapid advancement of urban construction, diversified scenarios such as rail transit stations, industrial plants, commercial complexes, underground parking lots, warehousing and logistics have an increasing demand for the multifunctionality (such as flood prevention and rodent prevention) of rolling shutter doors, which are key security facilities for achieving spatial isolation. The guide rail system, as a key facility for rolling shutter doors, plays a key role in the multifunctional integration of rolling shutter doors. However, traditional rolling shutter door guide rail systems have exposed many significant defects in application. In terms of adaptability, it is difficult to meet the structural dimensions and functional requirements of different scenarios. In the upgrade and renovation of existing facilities, it faces the problem of difficulty in adapting, resulting in the overall difficulty in meeting the operational and use needs of modern diversified scenarios; the functional integration is insufficient, and it is impossible to achieve the organic integration of multiple security functions. The specific problems are as follows: First, lack of adaptability: scenario compatibility is out of sync with functional requirements. Existing rolling shutter doors generally use a fixed slot width design, resulting in a lack of size adjustment and only adapting to a single thickness of rolling shutter door. When a building is retrofitted and upgraded with a rolling shutter, the guide rail system must be replaced simultaneously, which prolongs the renovation cycle and causes significant damage to the wall structure, resulting in material waste and a surge in construction costs.

[0003] Second, low functional integration: System siloing due to a single-function orientation. The design logic of traditional rolling shutter door guide rail systems is centered around "meeting basic lifting functions" and lacks a systematic architecture that addresses diverse needs such as anti-theft and flooding prevention. This results in each functional module operating in isolation.

[0004] Chinese patent CN202410700955.1 discloses a flood-proof rolling shutter door, which includes: a rolling shutter assembly, including multiple rolling shutter pieces and multiple flood-proof baffles connected in sequence, and each rolling shutter piece, each flood-proof baffle, and the rolling shutter piece and the flood-proof baffle are hinged; a rolling shutter mechanism, connected to the rolling shutter piece at the head end of the rolling shutter assembly, used to drive the multiple rolling shutter pieces and multiple flood-proof baffles to reel or extend; a clamping mechanism, including a first clamping assembly and a second clamping assembly, the first clamping assembly is used to clamp the multiple flood-proof baffles in the horizontal direction, and the second clamping assembly is used to clamp the multiple flood-proof baffles on the supporting surface in the vertical direction; a guide rail mechanism, a rolling shutter guide rail of the same width, used to raise the rolling shutter door and the flood-proof baffle.

[0005] The patented slide rail is essentially different from the traditional monorail guide rail. During installation, the original track and supporting embedded parts need to be removed, resulting in a zero reuse rate of existing facilities and a direct loss of initial investment.

[0006] Chinese patent CN202121020810.5 discloses a double-track flood-proof rolling shutter door device, which includes a rolling shutter mechanism and a flood-proof mechanism installed at the entrance and exit. It adopts double guide rails, and the rolling shutter mechanism and the flood-proof mechanism are arranged in front and behind. The rolling shutter mechanism includes a rolling shutter and a first driving mechanism for driving the rolling shutter to rise and fall. The flood-proof mechanism includes a waterproof baffle and a second driving mechanism for driving the waterproof baffle to rise and fall. The waterproof baffle includes multiple curtain plates, which are snap-connected to form a waterproof baffle body that can be rolled up and stored on the second drum. A local sealing strip is provided at the snap-connection between two adjacent curtain plates, and a bottom sealing strip is provided at the bottom of the waterproof baffle.

[0007] This patent applies to scenarios with limited building clearance, such as underground garage driveways and urban tunnel access corridors. The dual-track system requires additional installation depth, which reduces the effective width of narrow passageways. Furthermore, the renovation of older buildings often fails to meet the dual-track pre-buried installation requirements due to insufficient wall thickness. Summary of the Invention

[0008] The present invention is proposed to solve the problems existing in the prior art, and its purpose is to provide a rolling door guide rail device that is compatible with different thicknesses.

[0009] The technical solution of the present invention is: a rolling shutter door guide rail device compatible with different thicknesses, including a main rail assembly assembly and a secondary guide rail assembly assembly arranged on the side wall of the outer wall, the main rail assembly assembly is located inside the secondary guide rail assembly assembly, the main rail assembly assembly is installed with a rolling shutter main rail, the secondary guide rail assembly assembly is installed with a baffle secondary guide rail, the rolling shutter main rail guides the rolling shutter, and the baffle secondary guide rail installs and fixes the baffle.

[0010] Furthermore, the main rail assembly component is a flat steel fixed vertically at the outer wall, and the outer fixing surface of the flat steel is welded and fixed to the main rail of the rolling shutter.

[0011] Furthermore, the flat steel is laterally wider than the main roller shutter rail, and through holes are formed in the exposed sections on both sides of the flat steel, and expansion bolts are fixed to the outer wall through the through holes.

[0012] Furthermore, the auxiliary guide rail assembly assembly includes two angle steels, which are vertically and parallelly fixed to the side walls of the outer wall. Both angle steels include a fixed limb fixed to the outer wall and a vertical limb perpendicular to the outer wall, and an installation space is formed between the two vertical limbs.

[0013] Furthermore, the baffle auxiliary guide rail and the vertical limb of the angle steel are fixed by full welding.

[0014] Furthermore, a through hole is formed in the fixing limb of the angle steel, and the expansion bolt passes through the through hole and is fixed to the exterior wall.

[0015] Furthermore, flat steel is provided between the vertical limbs of the angle steel.

[0016] Furthermore, the baffle auxiliary guide rail and the roller shutter main guide rail realize the installation of the baffle.

[0017] Furthermore, the roller shutter main rail and the baffle auxiliary rail are both located on the inner side of the decoration surface.

[0018] The beneficial effects of the present invention are as follows: This invention optimizes installation space, and the guide rail assembly can adapt well to rolling shutter doors of varying thicknesses, breaking the limitation of traditional guide rails that can only accommodate rolling shutter doors of a single thickness. In projects, there is no need to customize guide rails for rolling shutter doors of different thicknesses, significantly reducing installation space. It also simplifies subsequent maintenance and improves the overall practicality of the system.

[0019] The present invention reduces occupied space and reduces the space originally occupied by two guide rails to one guide rail by providing a compatible guide rail.

[0020] The present invention has improved response time and fully considers the convenience of operation in its design. Usually, only one person is needed to complete the installation and disassembly work. In the event of an emergency, such as a flood disaster, it can respond quickly and quickly complete the opening and closing operation of the rolling shutter door, thereby buying precious time for the subway's flood prevention work and ensuring the safe operation of the subway.

[0021] The present invention saves costs, and the existing guide rails do not need to be dismantled and replaced, and only the foundation needs to be modified. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and embodiments: like Figures 1 to 5 As shown, a rolling shutter door guide rail device compatible with different thicknesses includes a main rail assembly assembly and a secondary guide rail assembly assembly arranged at the side wall of the outer wall 6, the main rail assembly assembly is located inside the secondary guide rail assembly assembly, the main rail assembly assembly is installed with a rolling shutter main rail 2, the secondary guide rail assembly assembly is installed with a baffle secondary guide rail 5, the rolling shutter main rail 2 guides the rolling shutter 10, and the baffle secondary guide rail 5 installs and fixes the baffle 11.

[0024] The main rail assembly component is a flat steel 3 vertically fixed to the outer wall 6, and the outer fixing surface of the flat steel 3 is welded and fixed to the main roller shutter rail 2.

[0025] The flat steel 3 is transversely wider than the main roller shutter rail 2 , and through holes are formed in the exposed sections on both sides of the flat steel 3 , through which expansion bolts 9 are passed to be fixed to the outer wall 6 .

[0026] The secondary guide rail assembly assembly includes two angle steels 7, which are fixed vertically and parallel to the side walls of the outer wall 6. The two angle steels 7 each include a fixed limb fixed to the outer wall 6 and a vertical limb perpendicular to the outer wall 6, and an installation space is formed between the two vertical limbs.

[0027] The baffle auxiliary guide rail 5 and the vertical limb of the angle steel 7 are fixed by full welding 4.

[0028] A through hole is formed in the fixing limb of the angle steel 7 , and the expansion bolt 9 is fixed to the outer wall 6 through the through hole.

[0029] Flat steel 3 is arranged between the vertical legs of the angle steel 7 .

[0030] The baffle auxiliary guide rail 5 and the roller shutter main guide rail 2 realize the installation of the baffle 11.

[0031] The roller shutter main rail 2 and the baffle auxiliary rail 5 are both located on the inner side of the decoration surface 15 .

[0032] Specifically, a rolling shutter box 1 is further provided between the outer walls of the outer wall 6 , and the rolling shutter 10 is stored in the rolling shutter box 1 .

[0033] Specifically, a bottom plate is further provided at the bottom of the angle steel 7, and the bottom plate is located between the fixed limb and the vertical limb. A bottom through hole is formed in the bottom plate, and a bottom bolt 13 passes through the bottom through hole to fix the bottom plate.

[0034] Specifically, the guide space of the baffle auxiliary guide rail 5 is laterally wider than the baffle 11 , and a pressing member 12 for pressing the baffle 11 is provided in the baffle auxiliary guide rail 5 .

[0035] Specifically, the bottom of the baffle auxiliary guide rail 5 is fixed by spot welding 14 .

[0036] Specifically, the guide rail device uses the outer wall 6 of the building as the basic bearing structure, and uses high-strength expansion bolts 9 to vertically fix the angle steel 7 and the roller shutter main rail 2 to the surface of the outer wall 6, thereby constructing a basic skeleton with rigid support capabilities.

[0037] More specifically, the angle steel 7 serves as a core load-bearing component, and its fixed limbs are mechanically connected to the outer wall 6 through expansion bolts 9 arranged at intervals, while the vertical limbs provide a precise installation reference for the baffle auxiliary guide rail 5.

[0038] Specifically, a sealing strip 8 is provided on the inner side of the main guide rail 2 of the rolling shutter, and the sealing strip 8 cooperates with the edge of the curtain plate of the rolling shutter 10 so that the curtain plate can be smoothly raised and lowered along the guide rail.

[0039] Specifically, the baffle auxiliary guide rail 5 is attached to the outer side of the roller shutter main rail 2 through high-strength expansion bolts 9. When it is necessary to isolate the space, the baffle 11 is pushed to the edge of the door opening, and the clamping part 12 on the water-facing surface fits tightly with the sealing strip 8 on the inner side of the baffle auxiliary guide rail 5 to form the required functional barrier.

[0040] Specifically, the exterior wall 6 forms the outermost portion of the structural system, and the angle steel 7 is mounted closely to the exterior wall 6, serving as auxiliary support for the guide rails. The roller shutter main rail 2 is vertically fixed to the exterior wall 6 or the angle steel 7, occupying a prime mounting point. Meanwhile, the baffle secondary guide rail 5 complements the roller shutter main rail 2, arranged either in parallel or nested around it, forming an integrated "shared guide rail" layout.

[0041] Specifically, baffles 11 are installed along the baffle secondary rails 5, deployed in functional areas for flood control. Roller shutters 10 are placed along the roller shutter primary rails 2, covering building interfaces requiring anti-theft protection. As the finished surface of a building, the decorative surface forms an internal and external layer with the exterior walls, rails, and other structures. The rails, angles, and other structures are located on the inside of the decorative surface, while the roller shutters can be installed to protrude from or flush against the decorative surface, depending on actual usage requirements.

[0042] This invention optimizes installation space, and the guide rail assembly can adapt well to rolling shutter doors of varying thicknesses, breaking the limitation of traditional guide rails that can only accommodate rolling shutter doors of a single thickness. In projects, there is no need to customize guide rails for rolling shutter doors of different thicknesses, significantly reducing installation space. It also simplifies subsequent maintenance and improves the overall practicality of the system.

[0043] The present invention reduces occupied space and reduces the space originally occupied by two guide rails to one guide rail by providing a compatible guide rail.

[0044] The present invention has improved response time and fully considers the convenience of operation in its design. Usually, only one person is needed to complete the installation and disassembly work. In the event of an emergency, such as a flood disaster, it can respond quickly and quickly complete the opening and closing operation of the rolling shutter door, thereby buying precious time for the subway's flood prevention work and ensuring the safe operation of the subway.

[0045] The present invention saves costs, and the existing guide rails do not need to be dismantled and replaced, and only the foundation needs to be modified.
