Description

Technical Field

[0001] This utility model belongs to the technical field of construction safety protection, specifically a protective device for working near the edge of high-rise buildings. Background Technology

[0002] During the construction, maintenance, or cleaning of high-rise buildings, there is a risk of falling from height when working near edges, such as exterior walls, floor slab edges, and roofs. This is one of the main causes of construction safety accidents.

[0003] The following are the commonly used protective measures when working near the edges of traditional high-rise buildings:

[0004] 1. Fixed guardrails: They require pre-installation, cannot flexibly adapt to temporary work needs, and may leave structural hazards after removal. Furthermore, disassembly and assembly are time-consuming and cannot be flexibly adjusted according to the construction progress.

[0005] 2. Temporary protective netting: Strong winds or falling objects can easily cause the protective structure to deform or collapse, posing a secondary safety hazard.

[0006] Therefore, how to effectively solve the problems of fixed guardrails not being able to be flexibly adjusted according to the construction progress, or temporary protective nets being prone to deformation of the protective structure when encountering strong winds or falling objects, are urgent technical issues that need to be addressed. Utility Model Content

[0007] In view of the shortcomings in the above-mentioned background technology, this utility model proposes a protective device for working near the edge of high-rise buildings, which solves the problems that fixed protective railings cannot be flexibly adjusted with the construction progress, or that temporary protective nets are prone to deformation of the protective structure when encountering strong winds or falling objects.

[0008] The technical solution of this application is as follows:

[0009] A protective device for working near the edge of high-rise buildings includes a protective plate unit for rotating with a floor slab, a second connector for detachably connecting to the structural steel frame, and a first connector for connecting to the floor slab. When the protective plate unit is positioned horizontally, ropes are sequentially connected to the protective plate unit, the second connector, and the first connector. When the protective plate unit is positioned vertically, both ends of the ropes are connected to the protective plate unit and the first connector, respectively. When the protective plate unit is horizontally deployed, the ropes form a triangular stable structure by connecting the protective plate unit, the second connector, and the first connector. Combined with a rotating reset assembly, this ensures both protective strength and reduces structural stress. When the protective plate unit is vertically positioned, the rotating reset assembly provides a self-locking force, while the first connector tightens the protective plate unit. The tension of the ropes is balanced with the backward thrust of the protective plate unit itself, enhancing the device's resilience.

[0010] Furthermore, the protective panel unit includes a composite canopy assembly and a frame assembly stacked together, and the composite canopy assembly and the frame assembly are connected by a lock.

[0011] Furthermore, the composite ceiling assembly includes an outer layer, a middle layer, and an inner layer connected in sequence. The inner layer is fitted with the frame assembly. The lock includes a U-shaped clip pre-embedded in the inner layer. The frame assembly includes a keel. The U-shaped clip passes through the keel and is positioned by the clip head and nut.

[0012] Furthermore, the bottom of the keel is provided with an arc surface for rotation, which rotates on the floor slab as the rope is loosened or tightened.

[0013] Furthermore, a rotary reset assembly is provided between the protective plate unit and the floor slab. The rotary reset assembly includes an L-shaped support connected to the floor slab, and a pin is connected to the L-shaped support. A torsion spring that fits the arc surface is sleeved on the outer wall of the pin. One end of the torsion spring presses on the outer layer and the other end presses on the floor slab. It is convenient to use and saves time and effort.

[0014] Furthermore, the protective plate unit is provided with the rotary reset assembly on both sides and in the middle, and the arc surface is provided with a clearance slot for the L-shaped support to pass through.

[0015] Furthermore, the outer wall of the keel is provided with feet for forming an angle with the floor slab.

[0016] Furthermore, the connector includes an expansion bolt embedded in the floor slab, with a loop for connecting a rope threaded to the top of the expansion bolt.

[0017] Furthermore, the second connector includes a U-shaped clip that engages with the outer steel frame of the structure. The U-shaped clip is detachably connected to the outer steel frame of the structure by bolts, and a pulley for ropes to pass through is connected to the bottom of the U-shaped clip.

[0018] Furthermore, the inner layer is equipped with a spray dust suppression interface, which can be used for dust suppression when needed on site. Emergency lighting equipment can also be added to adapt to the diverse needs of the construction site. It supports access to the construction site BIM management system and transmits data on temperature and humidity, dust concentration and structural health status of the protected area in real time.

[0019] The specific beneficial effects of this utility model include:

[0020] 1. When the protective plate unit is deployed horizontally, the rope forms a triangular stable structure by connecting the protective plate unit, connector two, and connector one. With the help of the rotating reset assembly, it ensures the protective strength while reducing structural stress. When the protective plate unit is used for vertical protection, the rotating reset assembly provides a self-locking force by pressing, and at the same time, the protective plate unit is tightened by connector one. The tension of the rope and the backward thrust of the protective plate unit are balanced, which enhances the risk resistance of the protective device.

[0021] 2. It replaces the traditional combination of metal fencing and dust netting, reducing costs. It can be reused multiple times after disassembly, making it easy to handle. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] A protective device for working near the edge of high-rise buildings, such as Figure 1 , Figure 3 As shown, the system includes a protective plate unit 3 for rotating with the floor slab 1, a second connector 6 for detachably connecting to the structural outer frame steel skeleton 2, and a first connector 5 for connecting to the floor slab 1. When the protective plate unit 3 is positioned horizontally, the rope 7 is connected sequentially to the protective plate unit 3, the second connector 6, and the first connector 5, and the rotation reset assembly 4 is in a relaxed state. When the protective plate unit 3 is positioned vertically, both ends of the rope 7 are connected to the protective plate unit 3 and the first connector 5, respectively, and the rotation reset assembly 4 is in a compressed state. When the protective plate unit 3 is horizontally deployed, the rope 7 forms a triangular stable structure by connecting the protective plate unit 3, the second connector 6, and the first connector 5, which, in conjunction with the rotation reset assembly 4, ensures both protective strength and reduces structural stress. When the protective plate unit 3 is vertically positioned, the rotation reset assembly 4 provides a self-locking force through compression, while the first connector 5 tightens the protective plate unit 3, balancing the tension of the rope 7 with the backward thrust of the protective plate unit 3 itself.

[0047] Specifically, the protective panel unit 3 can be deployed in 30 seconds by a single person through a rotating reset component 4 that can be released and pulled back.

[0048] Based on the above embodiments, as a preferred embodiment, the protective panel unit 3 includes a composite canopy assembly 31 and a frame assembly 32 stacked together, and the composite canopy assembly 31 and the frame assembly 32 are connected by a lock 33.

[0049] Preferably, the edge of the frame assembly 32 is embedded with a solar-powered LED strobe warning light strip, which has a built-in vibration sensor and automatically triggers an audible and visual alarm when it is impacted, and supports wireless data transmission to the management terminal.

[0050] Based on the above embodiments, as a preferred embodiment, such as... Figure 8 , Figure 9 As shown, the composite ceiling assembly 31 includes an outer layer 311, a middle layer 312, and an inner layer 313 connected in sequence. The inner layer 313 is attached to the frame assembly 32. The lock 33 includes a U-shaped clip 331 pre-embedded in the inner layer 313. The frame assembly 32 includes a keel. The U-shaped clip 331 passes through the keel and is positioned by the clip head 332 and the nut 333.

[0051] Specifically, the keel adopts a double-layer X-shaped reinforced frame, which is a double-layer cross-hinged structure made of galvanized steel pipes. Angle steel reinforcement plates are welded at the nodes. After unfolding, it forms a stable frame with a load-bearing capacity of ≥200kg / m² and a wind resistance level of 10.

[0052] Preferably, the outer layer 311 includes a honeycomb aluminum plate buffer layer filled with energy-absorbing foam to disperse the impact force of falling objects. The outer surface of the honeycomb aluminum plate buffer layer is provided with a high-density polyethylene wear-resistant mesh and a UV-resistant coating. The middle layer 312 can be made of flame-retardant non-woven fabric or puncture-resistant Kevlar fiber layer. The inner layer 313 can be made of removable activated carbon dust filter. At the same time, the outer layer 311, middle layer 312, and inner layer 313 can be replaced as needed, such as for dustproof, flame-retardant, and falling object prevention functions.

A gap is provided between the L-shaped support 41 and the arc surface for one end of the torsion spring 43 to extend and press on the floor slab 1. The pin 42 and the torsion spring 43 press on the arc surface, which limits the movement of the protective plate unit 3. The protective plate unit 3 rotates around the pin 42 and the torsion spring 43, which is convenient to use and saves time and effort.

[0056] Specifically, the L-shaped support 41 uses a Q345 steel base with ground nail slots or pre-embedded bolts on the edge to adapt to fixing uneven ground such as mud and gravel.

[0057] Based on the above embodiments, as a preferred embodiment, such as... Figure 6 As shown, the protective plate unit 3 is provided with the rotary reset component 4 on both sides and in the middle to avoid the protective plate unit 3 being too long and unstable.

The U-shaped clip 2 61 is detachably connected to the structural outer frame steel skeleton 2 by bolts 62, and a pulley 63 for the rope 7 to pass through is connected to the bottom of the U-shaped clip 2 61.

[0062] Specifically, the outer steel frame 2 can be an I-beam, and the opening of the U-shaped clip 61 is clipped onto the flange of the I-beam and pressed onto the flange of the I-beam by bolts 62.

[0063] Based on the above implementation method, as a preferred implementation method, the inner layer 313 is provided with a spray dust suppression interface, which can be used for dust suppression when needed on site. Specifically, emergency lighting equipment can also be added to adapt to the diverse needs of the construction site, support access to the construction site BIM management system, and transmit data on temperature and humidity, dust concentration, and structural health status of the protected area in real time.
