Description

Technical Field

[0001] The present invention relates to the technical field of building construction safety protection, and in particular to a modular high-altitude edge protection device and a use method thereof. Background Art

[0002] In the civil engineering construction of high-rise buildings, edge protection is a critical step in ensuring the safety of construction workers. This is especially true in projects employing the "uneven-height simultaneous ascent" construction method, where the inner concrete core is constructed first, followed by the outer steel frame, with a height difference. High-altitude edges are numerous, widely distributed, and their locations constantly change with the construction progress. Timely and reliable safety protection is crucial. Effective edge guardrails can significantly prevent people and materials from falling, avoiding major workplace accidents, and are a mandatory requirement of construction safety regulations.

[0003] In existing technology, a common approach to protecting horizontal openings and edges in core-to-frame steel structures with uneven construction heights is to weld rings or hooks to the outer frame steel columns and then run wire ropes between adjacent columns as a "lifeline." Construction workers must wear safety belts and attach the safety rope hooks to the lifeline before performing tasks like tying rebar at the floor edge. While this method provides adequate protection, running the wire ropes requires a large number of workers, impacting the work surface, or takes a long time, posing safety risks.

[0004] In order to overcome some of the shortcomings of traditional lifelines, a variety of standardized and tooled edge protection devices have emerged in the prior art. For example, China Utility Model Patent Publication No. CN220621166U discloses an edge protection device for high-altitude operations. The device mainly includes steel pipe columns, hanging plates, docking fasteners, cross bars, baffle hangers, movable clips, fixed clips, footboards and protective nets. Its characteristic is that it utilizes a clamping mechanism formed by a combination of movable clips and fixed clips to clamp on the edge of the floor working platform, and adapts to floor slabs of different thicknesses by adjusting the movable threaded sleeve. This solution solves the problem of fixed connection with the floor slab to a certain extent, and attempts to improve the adaptability to different working conditions.

[0005] However, upon analysis of the device disclosed in the above patent and similar technologies, the following key deficiencies still exist when applied to complex, fast-paced construction environments where the core tube and outer frame steel structures are simultaneously elevated at different heights: 1. Poor installation convenience and low efficiency: Although the clips are designed to accommodate varying floor thicknesses, the actual installation process is still cumbersome. Multiple threaded sleeves must be individually adjusted to clamp the floor slab, ensuring even force and a secure grip on each clip. This process is time-consuming and difficult to meet the requirements for timely follow-up protection in high-rise buildings, particularly when construction begins on the next floor, where effective protection must be established quickly. This bottleneck becomes installation speed.

[0006] 2. Insufficient integrity and modularity: The device was essentially constructed from multiple parts temporarily assembled on-site, lacking a highly pre-integrated modular design. To move it to an upper level as construction progressed, it had to be completely disassembled into its components, hoisted to the upper level, and then reassembled and adjusted piece by piece. This cycle of "disassembly-hoisting-reassembly-adjustment" was inefficient and severely limited the speed with which the protective device could be moved along with the structure. Summary of the Invention

[0007] The present invention provides a modular high-altitude edge protection device and a method for using the device, which solves the problems of poor installation convenience and low efficiency in the prior art.

[0008] The technical solution of the present invention is achieved as follows: A modular edge protection device for high places includes several protection units, each of which includes an upright and a clamping assembly. The clamping assembly is detachably mounted on the floor slab. The upper portion of the upright is connected to a protective structure. The sides of the protective structures in two adjacent protection units are interconnected. The upright passes through the clamping assembly, and a support structure is provided on the upright. The clamping assembly and the support structure are limitedly engaged. The protective structure is a baffle or a mesh. When the protection device is in use, the clamping assembly provides support to the upright through the support structure, thereby supporting the protective structure on the upright. The protective structures in each protection unit are connected to each other to form an edge protection device. In addition, when the protection structure is raised, the support structure on the upright can reach the clamping assembly on the upper floor slab and form a limited engagement with the clamping assembly, thereby achieving rapid fixation of the protective structure after it is raised.

[0009] The clamping assembly includes a base that is detachably connected to the floor slab; a fixed bracket is provided at the end of the base, and two clamping claws for clamping the vertical pole are movably connected to the fixed bracket. A movable bracket is slidably mounted on the base, and the movable bracket is connected to the clamping claws via a connecting rod. The movable bracket slides on the base to adjust the distance between the fixed bracket and the movable bracket. As the movable bracket slides, the movable bracket drives the connecting rod to swing, adjusting the angle between the connecting rod and the clamping claws to achieve opening or clamping of the clamping claws.

[0010] The clamping jaws are arranged in an S-shaped structure, with two jaws positioned opposite each other. The end of the fixed bracket is pivotally connected to the tail of the S-shaped structure, and the connecting rod is pivotally connected to the tail of the S-shaped structure. The two jaws are arranged on either side of the base. As the distance between the tail ends of the two jaws increases, the distance between the heads of the two jaws decreases, thereby clamping the opposing rod.

[0011] The fixed bracket and the movable bracket are connected by a spring. The spring is a tension spring that applies tension to the movable bracket, causing it to constantly move toward the fixed bracket. This ultimately keeps the clamping jaws in a constant clamping state, ensuring that the clamping assembly always clamps the upright pole in its natural state, ensuring the stability of the connection between the clamping assembly and the upright pole, and thus ensuring the stability of the clamping assembly's support for the protective structure.

[0012] The floor slab is provided with embedded parts, and the base is connected to the embedded parts. When the concrete pouring construction of the floor slab is carried out, the embedded parts are installed; the base and the embedded parts are detachably connected to realize the transfer or recovery of the clamping assembly.

[0013] The embedded component includes a vertical plate and a U-shaped structure. The vertical plate is connected to the bottom of the U-shaped structure and embedded in the floor slab. The base is connected to the U-shaped structure via connecting pins. The vertical plate is welded to the U-shaped structure. When the clamping assembly is installed, the base is placed in the U-shaped structure, and the side walls of the U-shaped structure limit the base in the left and right directions. Through holes are provided in the side walls of the base and the U-shaped structure. The connecting pins pass through the through holes in the base and the U-shaped structure to achieve axial positioning of the base within the U-shaped structure, ensuring stable installation of the base within the embedded component.

[0014] The support structure includes a support ring fixedly mounted on the vertical pole and cooperating with a clamping claw. The support ring is welded to the vertical pole, and the clamping claw provides support to the vertical pole through the support ring, thereby providing support to the protective structure at the upper end of the vertical pole.

[0015] A triangular support plate is installed on the upper side of the support ring. The vertical sides of the triangular plate are connected to the vertical pole, and the horizontal sides of the triangular plate are connected to the support ring. The hypotenuse of each triangular plate cooperates to form a guiding slope. When the vertical pole is raised, the support structure contacts the clamping assembly on the upper layer. The guiding slope formed by each support plate can open the clamping assembly's jaws, allowing the support ring to smoothly pass over the jaws and reach above the jaws. The vertical pole can then be lowered to reconnect the support structure and the clamping assembly, achieving a quick connection between the vertical pole and the clamping assembly after it is raised.

[0016] The vertical pole includes a guardrail support pole and an extension pole, the guardrail frame is connected to the guardrail support pole, the upper end of the guardrail support pole is provided with a hanging ring, and the lower end of the guardrail support pole is connected to the extension pole, which is convenient for disassembly of the vertical pole and convenient for storage and transportation of the vertical pole and the protective structure.

[0017] A method for using the high-altitude edge modular protection device includes a process of lifting the protection device: S1, disconnecting the protective structures of two adjacent protective units and lifting a single protective unit upward using a lifting device; the lifting device is a tower crane connected to a lifting ring at the top of the vertical pole, and the tower crane lifts the protective unit upward through the lifting ring to achieve the lifting of the protective structure; S2: During the rising process of the vertical pole, the support structure on the vertical pole contacts the clamping assembly on the upper floor slab. The support plate in the support structure opens the clamping jaws of the clamping assembly, allowing the support ring of the support structure to pass over the clamping jaws and reach above the clamping jaws. After the support ring passes over the clamping jaws, the clamping jaws re-clamp the vertical pole under the action of the spring; S3, using the lifting equipment to lower the pole and the protective structure so that the support ring contacts the clamping claw, and the clamping assembly provides support to the pole through the support structure; S4, remove the clamping assembly on the lowest floor corresponding to the protection unit, then move the removed clamping assembly to the uppermost floor for installation, and reconnect the clamping assembly to the vertical pole; pull out the connecting pin and remove the base from the U-shaped structure of the embedded part; S5, repeat S1 to S4 until all protective units are lifted and fixed in place; S6, reconnect the protective structure in the protective unit after lifting, and the lifting of the protective device is completed.

[0018] The beneficial effects of the present invention are: 1. The clamping assembly provides support for the vertical poles through the supporting structure, and then provides support for the protective structure, ensuring the stability of the installation of the vertical poles and the protective structure on the floor; and when the protective device is lifted, the lifted vertical poles and the supporting structure can quickly establish a connection relationship with the clamping assembly, and the workers only need simple operations to achieve the support of the supporting structure by the clamping assembly, which greatly simplifies the installation and fixing steps, shortens the protection establishment time, and greatly improves the overall turnover efficiency of the protective device as the structure climbs, while ensuring the safety of the staff when the protective device is lifted.

[0019] 2. The protective device is modularized and different numbers of protective units are installed according to different working conditions to improve the applicability of the protective device. The modular protection unit design supports overall lifting and hoisting, avoiding the inefficient process of complete disassembly and reinstallation in existing technologies.

[0020] 3. The vertical pole adopts a split structure, which is convenient for disassembly of the vertical pole and the storage and transportation of the vertical pole and protective structure. In addition, the clamping components can be removed from the floor after use and reused, which reduces the loss of parts and reduces the long-term use cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0025] Example 1, as Figure 1 、 Figure 2As shown, a modular protective device for high-altitude edges includes several protective units. Each protective unit includes a vertical pole 1 and a clamping assembly 3. The clamping assembly 3 is detachably mounted on a floor slab 6. The upper portion of the vertical pole 1 is connected to a protective structure 4. The sides of the protective structures 4 in two adjacent protective units are interconnected. The vertical pole 1 passes through the clamping assembly 3. The vertical pole 1 is provided with a support structure 2. The clamping assembly 3 and the support structure 2 are mutually limited. The protective device is modularly designed, and different numbers of protective units can be installed according to different working conditions, thereby improving the applicability of the protective device. Moreover, when the protective device is lifted, the protective unit can be lifted as a whole, eliminating the disassembly and reassembly process and improving the lifting efficiency of the protective device. When the protective device is in use, the vertical pole 1 is connected to the floor slab 6 through the clamping assembly 3. The clamping assembly 3 provides support for the vertical pole through the support structure 2, thereby supporting the protective structure 4. The various protective structures 4 are interconnected to form a protective barrier. In this embodiment, the protective structure 4 is a retaining net, and the sides of adjacent retaining nets are connected by connecting bolts 8.

[0026] Further, if Figure 3 As shown, the clamping assembly 3 includes a base 36, which is detachably connected to the floor slab 6. A fixed bracket 32 is provided at the end of the base 36, and two clamping jaws 31 for clamping the vertical pole 1 are movably connected to the fixed bracket 32. A movable bracket 34 is slidably provided on the base 3, and the movable bracket 34 is connected to the clamping jaws 31 via a connecting rod 33. The sliding movement of the movable bracket 34 on the base 36 adjusts the distance between the fixed bracket 32 and the movable bracket 34. As the movable bracket 34 slides, the movable bracket 34 drives the connecting rod 33 to swing, adjusting the angle between the connecting rod 33 and the clamping jaws 31 to achieve the opening or clamping of the clamping jaws 31.

[0027] Furthermore, the clamping jaws 31 are S-shaped, with two clamping jaws 31 arranged opposite each other. The end of the fixed bracket 32 is rotatably connected to the tail of the S-shaped structure, and the connecting rod 33 is rotatably connected to the tail of the S-shaped structure. The two clamping jaws 31 are arranged on either side of the base 36. When the distance between the movable bracket 34 and the fixed bracket 32 is reduced, the distance between the tail ends of the two clamping jaws 31 increases, and the distance between the heads of the two clamping jaws 31 decreases, thereby clamping the upright pole 1. Specifically, the inner side of the head of the clamping jaw 31 is an arc-shaped structure. When the clamping jaw 31 clamps the upright pole 1, the arc-shaped structure mates with the outer circumference of the upright pole 1, ensuring the stability of the clamping jaw 31 on the upright pole 1.

[0028] Furthermore, the fixed bracket 32 and the movable bracket 34 are connected by a spring. The spring is a tension spring that applies tension to the movable bracket 34, causing the movable bracket 34 to always move toward the fixed bracket 32. Ultimately, this keeps the clamping jaws 31 in a clamped state, ensuring that the clamping assembly 3 always clamps the upright pole 1 in its natural state, ensuring the stability of the connection between the clamping assembly 3 and the upright pole 1, and thus ensuring the stability of the support provided by the clamping assembly 3 to the protective structure 4.

[0029] Example 2 differs from Example 1 in that it is a modular protective device for high-altitude edges, with two clamping jaws 31 arranged crosswise, the middle parts of the two clamping jaws 31 being rotatably connected to the fixed bracket 32 at the end of the base 36, and the tail ends of the clamping jaws 31 being connected to the movable bracket 34 through the connecting rod 33. When the distance between the movable bracket 34 and the fixed bracket 32 increases, the distance between the tail ends of the two clamping jaws 31 is reduced. At this time, the distance between the heads of the two clamping jaws 31 is reduced, thereby achieving clamping of the opposing rod 1.

[0030] Furthermore, a compression spring is provided between the fixed bracket 32 and the movable bracket 34. The compression spring applies a thrust to the movable bracket 34, so that the movable bracket 34 always moves away from the fixed bracket 32, and finally the clamping claw 31 is always in a clamping state, ensuring that the clamping assembly 3 always clamps the vertical pole 1 in a natural state, ensuring the connection stability of the clamping assembly 3 and the vertical pole 1, and further ensuring the support stability of the clamping assembly 3 on the protective structure 4.

[0031] Example 3, based on Example 1, a modular protection device for high-altitude edges, each protection unit is provided with at least three clamping assemblies 3 connected. Each clamping assembly 3 is provided on the corresponding floor slab 6, and multiple support structures 2 are provided on the vertical pole 1. The distance between the upper and lower support structures 2 is equal to the floor height, so that the clamping assemblies 3 on each floor slab 6 can provide support for the support structure 2, ensuring the support strength and stability of the clamping assemblies 3 for the vertical pole 1. When the vertical pole 1 and the protective structure 4 are lifted, after the vertical pole 1 is separated from the clamping assembly 3 on the lowest floor slab 6, at least two clamping assemblies 3 are still there to provide support and limit the vertical pole 1, effectively ensuring the stability and safety of the vertical pole 1 and the protective structure 4 during the lifting process.

[0032] Example 4, based on Example 1, is a modular protection device for high-rise edges, wherein a pre-embedded part 5 is provided on the floor 6, and a base 36 is connected to the pre-embedded part 5. When the floor 6 is concreted, the pre-embedded part 5 is installed; the removable connection between the base 26 and the pre-embedded part 5 enables the clamping assembly 3 to be repeatedly installed, used, and recycled. Figure 4As shown, the embedded component 5 includes a vertical plate 51 and a U-shaped structure 52. The vertical plate 51 is connected to the bottom of the U-shaped structure 52 and is embedded in the floor slab 6. The base 36 is connected to the U-shaped structure 52 via a connecting pin 53. The vertical plate 51 and the U-shaped structure 52 are welded together. When the clamping assembly 3 is installed, the base 36 is placed in the U-shaped structure 52, and the side walls of the U-shaped structure 52 limit the left and right positions of the base 36. The side walls of the base 36 and the U-shaped structure 52 are each provided with through holes. The connecting pin 53 passes through the through holes in the base 36 and the U-shaped structure 52 to limit the axial position of the base 36 in the U-shaped structure 52, ensuring that the base 36 is stably installed in the embedded component 5.

[0033] Furthermore, a plurality of through holes arranged transversely side by side are provided on the side walls of the U-shaped structure 52, and the through holes on the base 36 correspond to the through holes at different positions on the U-shaped structure 52, so that the position of the clamping assembly 3 on the embedded part 5 can be adjusted, and then the length of the clamping assembly 3 extending out of the floor 6 can be adjusted, thereby improving the applicability of the device.

[0034] Example 5 differs from Example 4 in that it is a modular protective device for high-altitude edges, and the side walls of the U-shaped structure 52 are provided with transversely arranged long holes, which are connected to nuts after passing through the long holes and the through holes on the base 36. After the nuts are tightened, the position of the base 36 in the U-shaped structure 52 can be fixed to ensure the installation stability of the base 36; and the sliding of the fixing studs in the long holes can realize the position adjustment of the clamping assembly 3 on the embedded part 5, and then adjust the length of the clamping assembly 3 extending out of the floor 6, thereby improving the applicability of the device.

[0035] Example 6, based on Example 4, provides a modular high-rise edge protection device. The support structure 2 includes a support ring 21, which is fixedly mounted on the vertical pole 1 and engages with a clamping claw 31. The lower surface of the support ring 21 engages with the upper surface of the clamping claw 31, which is welded to the vertical pole 1. The clamping claw 31 provides support to the vertical pole 1 through the support ring 21, thereby providing support to the protective structure 4 at the upper end of the vertical pole 1.

[0036] Furthermore, a support plate 22 is provided on the upper side of the support ring 21. The support plate 22 is a triangular plate, the vertical side of the triangular plate is connected to the upright pole 1, and the horizontal side of the triangular plate is connected to the support ring 21. The hypotenuse of each triangular plate cooperates to form a guiding slope. When the upright pole 1 is lifted, the support structure 2 contacts the clamping assembly 3 of the upper layer. The guiding slope formed by each support plate 22 can open the clamping jaw 31 of the clamping assembly 3, so that the support ring 21 can smoothly pass over the clamping jaw 31 to reach above the clamping jaw 31. Then, the upright pole 1 can be lowered to achieve the reconnection of the support structure 2 and the clamping assembly 3, realizing a quick connection between the upright pole 1 and the clamping assembly 3 after lifting.

[0037] Furthermore, the vertical pole 1 includes a guardrail support rod and an extension rod. The guardrail frame 4 is connected to the guardrail support rod. The upper end of the guardrail support rod is provided with a lifting ring, and the lower end of the guardrail support rod is connected to the extension rod. The lifting ring facilitates the use of lifting equipment to lift the protective unit. Specifically, the lower end of the protective support rod and the lower end of the extension rod are both provided with threaded holes, and the upper end of the extension rod is provided with a threaded rod. When the guardrail support rod is connected to the extension rod, the threaded rod at the upper end of the extension rod is connected to the threaded hole at the lower end of the guardrail support rod; two adjacent extension rods are connected end to end. The vertical pole 1 adopts a split structure, which facilitates the disassembly of the vertical pole 1 and the storage and transportation of the vertical pole 1 and the protective structure 4.

[0038] Example 7 differs from Example 6 in that it is a modular protective device for high-rise edges, in which a buffer ring is sleeved on the vertical pole 1 and located on the lower side of the support ring 21. The buffer ring is connected to the support ring 21 via a buffer spring. When the clamping assembly 3 supports the support structure 2, the upper surface of the clamping claw 31 contacts the lower surface of the buffer ring. The provision of the buffer ring can mitigate the impact generated when the vertical pole 1 and the protective structure 4 fall, ensuring the structural safety of the clamping assembly 3. In addition, the buffer ring can eliminate the error between the distance between the upper and lower support structures 2 and the floor height, so that the clamping assembly 3 on each floor slab 6 can provide support to the support structure 2, thereby improving the structural stability of the protective device.

[0039] Example 8 differs from Example 6 in that it is a modular protective device for high edges, wherein an arc-shaped buffer plate is provided above the clamping jaw 31, and the arc-shaped buffer plate is connected to the upper surface of the clamping jaw 31 by a buffer spring. When the clamping assembly 3 supports the supporting structure 2, the upper surface of the arc-shaped buffer plate contacts the lower surface of the supporting ring 21. The setting of the arc-shaped buffer plate can reduce the impact generated when the vertical pole 1 and the protective structure 4 fall, thereby ensuring the structural safety of the clamping assembly 3; in addition, the arc-shaped buffer plate can eliminate the error between the distance between the upper and lower supporting structures 2 and the floor height, so that the clamping assembly 3 on each floor slab 6 can provide support force to the supporting structure 2, thereby improving the structural stability of the protective device.

[0040] Example 9, based on Example 1, a method for using the high edge modular protection device, including the protection device lifting process: S1, disconnect the connection between the protective structures 4 in two adjacent protective units, and use a lifting device to lift a single protective unit upward; specifically, remove the connecting bolts 8 used to connect the two protective structures 4, so that the sides of the two protective structures 4 are disconnected, and the lifting equipment uses a tower crane, connect the hook of the tower crane to the lifting ring at the top of the vertical pole 1, and the tower crane directly lifts the vertical pole 1 and the protective structure 4 upward, and the clamping assembly 3 corresponding to the lower end of the vertical pole 1 is separated from the vertical pole 1, while ensuring that the vertical pole 2 is connected to the floor slab 6 through at least two clamping assemblies 3.

[0041] S2, during the rising process of the vertical pole 1, the supporting structure 2 on the vertical pole 1 contacts the clamping assembly 3 on the upper floor slab, and the supporting plate 22 in the supporting structure 2 opens the clamping claw 31 of the clamping assembly 3, so that the supporting ring 21 of the supporting structure 2 passes over the clamping claw 31 and reaches above the clamping claw 31; when the vertical pole 1 and the protective structure 4 rise to the height of one floor, the supporting structure 2 contacts the clamping assembly 3 on the upper floor slab 6; after the supporting ring 21 passes over the clamping claw 31, under the action of the spring between the movable bracket 34 and the fixed bracket 32, the movable bracket 34 is driven to move, so that the clamping claw 31 re-clamps the vertical pole 1.

[0042] S3, use the lifting equipment to lower the vertical pole 1 and the protective structure 4, so that the supporting ring 21 contacts the clamping claw 31, and the clamping assembly 3 provides support for the vertical pole 1 through the supporting structure 2; at this time, the hook of the tower crane can be disconnected from the lifting ring, and prepare to lift another protective unit.

[0043] S4, remove the clamping assembly 3 on the lowest floor 6 corresponding to the protective unit from the floor 6, then move the removed clamping assembly 3 to the uppermost floor 6 for installation, and reconnect the clamping assembly 3 to the vertical pole 1; when removing the clamping assembly 3, directly disconnect the connection between the base 36 and the embedded part 5.

[0044] S5, repeat S1 to S4 until all protective units are lifted and fixed in place; S6, reconnect the protective structure 4 in the raised protective unit, and the overall lifting of the protective device is completed.
