Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an edge protection device. Background Technology

[0002] In construction sites, when working at heights, if the edge of the working surface lacks protective facilities or if protective facilities are present but their height is less than 800mm, this type of work is called edge work. All construction work in such edge-prone situations falls under the category of edge work. Furthermore, on general construction sites, there are also ground-level works, and work along their edges is also considered edge work. Examples include: the edges of ditches, pits, trenches, the perimeter of deep foundations, the perimeter of floors, the sides of staircases, the edges of platforms or balconies, and the edges of roofs.

[0003] While installing protective fences can effectively reduce the risk of falls during edge work, there is still a risk of falling debris such as welding slag, broken concrete, or tools, which can cause injuries. These falling objects can cause personal injury and property damage to people below. Current protective measures typically involve setting up warning zones, hanging signs and markers to alert pedestrians, but these measures cannot completely prevent accidents. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an edge protection device, which is mainly used for edge protection to solve the safety hazard of falling objects from heights during edge operations. It is also easy to disassemble and assemble and is suitable for different construction sites.

[0005] This utility model discloses an edge protection device, including a support frame installed in the working surface. The support frame includes vertical steel pipes, horizontal steel pipes, and longitudinal steel pipes that form a frame structure. The vertical steel pipes, horizontal steel pipes, and longitudinal steel pipes are detachably connected. The horizontal steel pipes include a first steel pipe installed at the top of the support frame and a second steel pipe installed in the middle of the support frame. One end of the first steel pipe extends outside the working surface and is detachably connected to a collection device for collecting materials. The collection device includes a connecting steel pipe installed parallel to the longitudinal steel pipe and connected to the first steel pipe. Each first steel pipe has a vertical steel pipe on both sides at the end away from the support frame, which is parallel to the vertical steel pipe and detachably connected to the connecting steel pipe. The vertical steel pipe extends vertically downward and its lower end is detachably connected to a storage basket facing the support frame. The support frame and the collection device form an operating space for operators to carry out construction.

[0006] Furthermore, the storage basket includes a frame support made of steel pipes, and the inner side of the frame support is provided with a steel plate for sealing the side wall and bottom of the frame support to form a material storage cavity. The steel plate is welded to the frame support.

[0007] As a preferred embodiment, a reinforcing steel pipe is provided between two adjacent vertical steel pipes, parallel to the vertical steel pipes. The upper end of the reinforcing steel pipe is detachably connected to the connecting steel pipe, and the lower end of the reinforcing steel pipe is connected to the storage basket.

[0008] Furthermore, at least four of the second steel pipes are evenly distributed in the middle of the support frame and are detachably connected to two longitudinal steel pipes located on the same horizontal plane to form a loading platform, wherein a counterweight is provided on the loading platform.

[0009] Furthermore, each of the vertical steel pipes is provided with a roller at its bottom, and the roller is provided with a brake pad for braking.

[0010] As a preferred embodiment, an mounting plate with a radius larger than that of the vertical steel pipe is provided above the roller. A rod extending into the vertical steel pipe is provided at the center of the mounting plate. A lifting plate is provided on the rod. The lifting plate is threadedly connected to the rod, and the radius of the lifting plate is larger than that of the vertical steel pipe. The upper surface of the lifting plate is in contact with the lower surface of the vertical steel pipe.

[0011] The beneficial effects of this utility model are as follows: This edge protection device sets up a support frame located within the working surface at the edge, and a collection device for material collection is set on the outside of the working surface at the edge via a first steel pipe extending outward from the top of the support frame. This allows for the timely collection of welding slag, broken concrete, or tools that fall from the working surface to the outside during edge work, thus solving the safety hazard of falling objects from heights during edge work. Furthermore, the support frame and collection device are both made of steel pipes and steel pipe fasteners, making assembly and disassembly simple. It is suitable for different construction sites, and workers can easily assemble it. It can also be assembled directly using steel pipe scaffolding on the construction site, using locally sourced materials without the need for separate purchases. In addition, since the device is assembled from steel pipes, it can be recycled and reused after use, saving costs. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below.

[0017] This utility model provides an edge protection device, mainly used for edge protection and material collection. It includes a support frame 1 installed within the working surface. The support frame 1 comprises a vertical steel pipe 11, a horizontal steel pipe 12, and a longitudinal steel pipe 13 forming a frame structure. The vertical steel pipe 11, horizontal steel pipe 12, and longitudinal steel pipe 13 are detachably connected. The horizontal steel pipe 12 includes a first steel pipe 121 installed at the top of the support frame 1 and a second steel pipe 122 installed in the middle of the support frame 1. One end of the first steel pipe 121 extends beyond the working surface and can... A collection device 2 for collecting materials is detached and connected. The collection device 2 includes a connecting steel pipe 21 that is parallel to the longitudinal steel pipe 13 and connected to the first steel pipe 121. Each first steel pipe 121 has a vertical steel pipe 22 that is parallel to the vertical steel pipe 11 and detachably connected to the connecting steel pipe 21 on both sides of the end away from the support frame 1. The vertical steel pipe 22 extends vertically downward and its lower end is detachably connected to a storage basket 23 that faces the support frame 1. An operating space 5 for operators to carry out construction is formed between the support frame 1 and the collection device 2.

[0018] like Figure 1 , Figure 2As shown, the edge protection device includes a support frame 1 installed within the working surface. The support frame 1 is constructed from vertical steel pipes 11, horizontal steel pipes 12, and longitudinal steel pipes 13 connected by steel pipe fasteners to form a frame structure, which provides stable support. Since the support frame 1 is constructed from detachable and overlapping vertical steel pipes 11, horizontal steel pipes 12, and longitudinal steel pipes 13, suitable steel pipe sizes can be selected at the construction site according to the conditions of the edge operation, making it suitable for different construction sites. A first steel pipe 121 is installed at the top of the support frame 1, higher than the guardrail assembly installed during edge operations, thus avoiding interference with the guardrail assembly. A collection device 2 is connected to the end of the first steel pipe 121 furthest from the support frame 1. This collection device 2 is located outside the working surface during edge operations to collect debris falling from the working surface. The collection device 2 collects welding slag, broken concrete, or tools that fall from the side to prevent objects from falling from heights. Specifically, the collection device 2 includes a connecting steel pipe 21 parallel to the longitudinal steel pipe 13 and connected to the first steel pipe 121. The connecting steel pipe 21 is detachably connected to the two first steel pipes 121 via steel pipe fasteners. Each first steel pipe 121 has vertical steel pipes 22 on both sides away from the support frame 1. The lower end of the vertical steel pipe 22 is detachably connected to a collection basket 23 facing the support frame 1. The height of the collection basket 23 from the first steel pipe 121 is controlled by the vertical steel pipe 22 so that it is located below the working surface of the edge work, so as to collect welding slag, broken concrete, or tools that fall from the working surface to the outside during edge work in a timely manner, thereby solving the safety hazard of objects falling from heights during edge work. The support frame 1 and the collection device 2 form an operating space 5 for operators to carry out edge work. This edge protection device consists of a support frame 1 located within the working surface at the edge, and a collection device 2 for collecting materials located on the outer side of the working surface via a first steel pipe 121 extending from the top of the support frame 1 outwards. This allows for the timely collection of welding slag, broken concrete, or tools that fall from the working surface to the outer side during edge operations, thus mitigating the safety hazard of falling objects from heights. Both the support frame 1 and the collection device 2 are made of steel pipes and steel pipe fasteners, making assembly and disassembly simple and suitable for different construction sites. Workers can easily assemble it, and it can be directly assembled using steel pipe scaffolding on the construction site, utilizing local materials without the need for separate procurement. Furthermore, since the device is assembled from steel pipes, it can be recycled and reused after use, saving costs.

[0019] To save costs, the storage basket 23 includes a frame support 231 made of steel pipes. The inner side of the frame support 231 is provided with a steel plate 232 for sealing the side walls and bottom of the frame support 231 to form a material storage cavity 233. The steel plate 232 is welded to the frame support 231. Figure 1 , Figure 2 As shown, the storage basket 23 is made of a frame support 231 formed by steel pipes and a steel plate 232. Specifically, as shown... Figure 1 As shown, the frame support 231 can be made of multiple steel pipes. The size of the frame support 231 can be designed according to the size of the edge of the working surface to meet the needs of collecting materials generated during construction at the edge of the working surface. The vertical steel pipe 22 is then connected to the frame support 231. The inside of the frame support 231 is sealed with steel plate 232 to form a material storage cavity 233. The entire storage basket 23 is made of materials such as steel pipes and steel plate 232 that are already available on the construction site, without the need for additional purchases, effectively saving production costs and allowing for repeated use.

[0020] To ensure that the frame support 231, constructed from overlapping steel pipes, can be stably mounted on the first steel pipe 121, such as Figure 1 , Figure 2 As shown, a reinforcing steel pipe 24 is also provided between two adjacent vertical steel pipes 22, parallel to the vertical steel pipes 22. The upper end of the reinforcing steel pipe 24 is detachably connected to the connecting steel pipe 21, and the lower end of the reinforcing steel pipe 24 is connected to the storage basket 23. By adding the reinforcing steel pipe 24, the connection stability between the connecting steel pipe 21 and the frame support 231 is enhanced, ensuring the connection stability between the storage basket 23 and the first steel pipe 121, preventing it from falling off during use. Furthermore, the reinforcing steel pipe 24 is detachably connected to the connecting steel pipe 21, allowing for disassembly and storage when not in use, and repeated use.

[0021] To balance the weight between the support frame 1 and the collection device 2, and to prevent the support frame 1 from becoming unbalanced and falling due to excessive material collected in the collection device 2, such as... Figure 1 As shown, at least four second steel pipes 122 are evenly arranged in the middle of the support frame 1 and are detachably connected to two longitudinal steel pipes 13 located on the same horizontal plane to form a loading platform. The loading platform is provided with counterweights 3. The loading platform is formed by the second steel pipes 122 and the longitudinal steel pipes 13 to place the counterweights 3. No additional components are required. The counterweights 3 are increased or decreased according to the weight of the material stored in the collection device 2 to ensure the balance between the support frame 1 and the collection device 2.

[0022] To facilitate the relocation of the entire edge protection device, its position can be adjusted according to the location of the edge construction, making it suitable for edge construction protection in different locations, such as... Figure 1As shown, each of the vertical steel pipes 11 is equipped with a roller 4 at its bottom, and the roller 4 is equipped with a brake pad 41 for braking. The through-hole roller 4 drives the entire edge protection device to move, and the brake pad 41 controls the start and stop of the roller 4 to prevent the edge protection device from shifting during use, which could cause a gap between the collection device 2 and the working surface, allowing materials such as welding slag generated during edge construction to fall and cause a falling object accident. As a preferred method, to make this edge protection device suitable for edge construction protection with height differences, such as stairwells, etc., Figure 3 As shown, an mounting plate 42 with a radius larger than that of the vertical steel pipe 11 is provided above the roller 4. A rod 43 extending into the vertical steel pipe 11 is located at the center of the mounting plate 42. A lifting plate 44 passes through the rod 43. The lifting plate 44 is threadedly connected to the rod 43, and its radius is larger than that of the vertical steel pipe 11. The upper surface of the lifting plate 44 contacts the lower surface of the vertical steel pipe 11. By providing a rod 43 inserted into the vertical steel pipe 11 above the roller 4, the roller 4 can be stably installed below the support frame 1 to drive the entire edge protection device. The roller 4 is movable and easy to disassemble and replace; a lifting plate 44 is threaded onto the insertion rod 43, and the lifting plate 44 is threaded to the insertion rod 43. By rotating the lifting plate 44, the lifting plate 44 can be moved along the length of the insertion rod 43, thereby adjusting the height of the vertical steel pipe 11 connected to the roller 4, making it suitable for edge protection construction with height differences, such as stairwells; of course, since the vertical steel pipe 11, horizontal steel pipe 12 and longitudinal steel pipe 13 are detachably connected, edge protection can be carried out by rebuilding the support frame 1 suitable for the application site, but the disassembly and assembly time is long and manpower is consumed.
