Description

Technical Field

[0001] This application relates to the technical field of edge guardrails, and specifically to an edge guardrail structure for construction projects. Background Art

[0002] An edge guardrail, also known as an edge protection railing, is a railing system installed at the edge to prevent people from accidentally falling or coming into contact with dangerous areas. This facility is widely used in various places and environments such as construction sites, subway construction, viaducts, stairs, platforms, open-air platforms, the outer walls or balconies of high-rise buildings, and corridors.

[0003] Most of the existing edge guardrails are fixed to the edge of the construction site by a fixed installation method to prevent loosening and ensure safety. Moreover, the guardrail is an integrated design. Therefore, when the guardrail is reused, it needs to be disassembled and assembled again, which is rather cumbersome. In addition, the integrated guardrail is large in volume and inconvenient to carry.

[0004] Therefore, this application provides an edge guardrail structure for construction projects to solve the above problems. Utility Model Content

[0005] This application provides an edge guardrail structure for construction projects, aiming to solve the problem that the existing edge guardrails are not convenient for reuse and transportation proposed in the background art.

[0006] To achieve the above object, this application provides the following technical solution: An edge guardrail structure for construction projects includes a first guardrail plate and a second guardrail plate hinged to the first guardrail plate through a hinge.

[0007] At both ends where the first guardrail plate and the second guardrail plate are away from each other, they are both connected to a fixed column inserted at the corner of the construction site through two groups of connecting pieces.

[0008] The connecting member includes a slider slidably connected to the mutually remote sides of the first guardrail plate and the second guardrail plate, fixed cylinders symmetrically fixed to one side of the slider close to the fixed column, telescopic rods telescopically connected to the ends of the fixed cylinders remote from the slider, hinge seats fixedly connected to the ends of the two telescopic rods remote from the fixed cylinders, quick-release buckles hinged to the hinge seats for hooking onto the fixed column, and a tension spring sleeved outside the fixed cylinders and the telescopic rods for moving the hinge seats away from the fixed column; due to the adoption of the hinge structure and the detachable connecting member design, this edge guardrail structure is easy to reassemble after disassembly, improving the reusability of the guardrail. Whether at different positions on the same construction site or at other construction sites, it can be conveniently reused. The volume of the two guardrail plates after folding is significantly reduced, facilitating handling and storage. This not only reduces the labor intensity of workers but also improves construction efficiency. The telescopic rods and quick-release buckles on the connecting member enable the guardrail to adapt to fixed columns with different spacings, improving the flexibility and adaptability of installation. Due to the reasonable design and easy reusability of the guardrail structure, the cost caused by frequent replacement or re-production of the guardrail is reduced.

[0009] Preferably, the two ends of the tension spring are respectively connected to the hinge seat and the slider to ensure the stability and normal operation of the tension spring.

[0010] Preferably, symmetrically arranged upper and lower limiting sliding grooves for slidably connecting with the slider are formed on the mutually remote sides of the first guardrail plate and the second guardrail plate. The limiting sliding grooves limit the up-and-down movement range of the connecting member, helping to make the supporting force received by the guardrail plate uniform and improving the overall stability of the guardrail.

[0011] Preferably, the bottoms of the fixed columns are all conical. With the conical heads at the bottoms of the fixed columns, it is easier to insert into the deep ground, which is beneficial for saving effort.

[0012] Preferably, the hinge member is of a split design. The hinge member includes a plug-in part and a cap part sleeved on the plug-in part. Ear parts for fixing and installing on the first guardrail plate or the second guardrail plate by screws are provided on both the plug-in part and the cap part. Since the hinge member is of a split design and is easy to disassemble and replace, in case of damage or wear during long-term use, the repair or replacement work can be conveniently carried out. This helps to reduce the maintenance cost and extend the service life of the guardrail structure. The detachable hinge member also allows the guardrail to be disassembled in addition to being folded for storage, enabling more flexible handling.

[0013] Preferably, there are two semi-circular chucks symmetrically arranged on the plug, which are close to or away from each other. The two semi-circular chucks form a mushroom-shaped pin rod. A locking groove is provided at one end of the cap away from the plug. The outer diameter of the pin rod is slightly larger than the inner diameter of the cap. A button is movably connected in the locking groove, which moves closer to or away from the pin rod and fits with the end of the pin rod. By squeezing the two semi-circular chucks, they are made to approach each other to disengage from the button in the locking groove. The design of the mushroom-shaped pin rod makes the connection between the plug and the cap more stable. In the locked state, the two semi-circular chucks are in close contact with the inner wall of the locking groove and are not likely to loosen or fall off, thus improving the overall stability of the guardrail structure. Through the design of the button, the quick disassembly between the plug and the cap can be conveniently achieved. Workers only need to press the button to unlock the pin rod, and the articulated parts can be easily separated without using special tools, greatly improving the disassembly efficiency.

[0014] Preferably, a splicable splicing guardrail plate is provided between the first guardrail plate and the second guardrail plate. Two juxtaposed plugs and two juxtaposed caps are respectively installed at both ends of the splicing guardrail plate. By providing a splicable splicing guardrail plate between the first guardrail plate and the second guardrail plate, the length of the guardrail can be extended by splicing multiple groups of splicing guardrail plates, so as to meet construction sites of different sizes and dimensions, with high flexibility. Moreover, it is unnecessary to customize guardrails for different construction sites, saving costs and increasing the reuse rate.

[0015] This construction project edge guardrail structure, combined with the optimized split articulated parts and mushroom-shaped pin rod locking mechanism, significantly improves the flexibility, adaptability and economy of the guardrail structure. It also simplifies the installation and disassembly process, enhances the safety and stability of the guardrail structure, and provides an efficient and convenient edge protection solution for various construction environments.

[0016] This construction project edge guardrail structure, by introducing the design of splicable splicing guardrail plates, not only reduces costs and increases the reuse rate, but also enhances the adaptability of the guardrail structure and simplifies the installation process.

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] Embodiment 1

[0028] This embodiment provides a structure for the edge guardrail of a construction project, as Figures 1 - 3 shown. The structure for the edge guardrail of this construction project includes a first guardrail panel 1 and a second guardrail panel 2 hinged to the first guardrail panel 1 through a hinge 3;

[0029] At both ends where the first guardrail panel 1 and the second guardrail panel 2 are far away from each other, they are both connected to a fixed column 5 inserted at the corner of the construction site through two groups of connecting pieces 4;

[0030] The connecting piece 4 includes a slide block 41 slidably connected to the sides where the first guardrail panel 1 and the second guardrail panel 2 are far away from each other, fixed cylinders 42 symmetrically fixed on the side of the slide block 41 close to the fixed column 5, telescopic rods 43 telescopically connected to the ends of the fixed cylinders 42 far away from the slide block 41, hinge seats 44 fixedly connected to the ends of the two telescopic rods 43 far away from the fixed cylinders 42, quick-release buckles 46 hinged on the hinge seats 44 for hanging on the fixed column 5, and tension springs 45 sleeved outside the fixed cylinders 42 and the telescopic rods 43 for moving the hinge seats 44 away from the fixed column 5. Among them, the two ends of the tension spring 45 are respectively connected to the hinge seat 44 and the slide block 41.

[0031] When in use, when it is necessary to install the guardrail, unfold two guardrail plates and stand them on the edge of the construction site. At one end where the two guardrail plates are away from each other, connect them to the fixed columns 5 inserted at the corners of the construction site through two sets of connecting pieces 4. The specific operation is to buckle the quick-release buckle 46 on the fixed column 5. At this time, the tension of the tension spring 45 tightens the guardrail plate and the fixed column 5, keeping them stable and providing buffering when the guardrail plate is impacted. When buckling adjacent edges, adjust the position by moving the slider 41 to avoid the overlapping of the quick-release buckles 46 on adjacent edges, which may prevent buckling. When it is necessary to disassemble or carry, release the quick-release buckle 46 from the fixed column 5, release the guardrail plate, pull out the fixed column 5, and then fold the two guardrail plates to reduce the volume, facilitating the carrying operation.

[0032] Wherein, on one side where the first guardrail plate 1 and the second guardrail plate 2 are away from each other, symmetrically upper and lower limit sliding grooves 7 that are slidably connected to the slider 41 are provided; when adjusting the position of the connecting piece 4 by moving the slider 41, the limit sliding groove 7 is used to limit its moving range to ensure that the guardrail plate obtains a stable stress point.

[0033] Specifically, the bottom ends of the fixed columns 5 are all set to be conical; when fixing the fixed columns 5 on soft soil, the conical bottom ends of the fixed columns 5 can be inserted into deeper soil, which is labor-saving and ensures firmness.

[0034] Furthermore, the hinge piece 3 is of a split design. The hinge piece 3 includes a plug-in part 31 and a cap part 32 sleeved on the plug-in part 31. Both the plug-in part 31 and the cap part 32 are provided with ear parts 34 for being fixedly installed on the first guardrail plate 1 or the second guardrail plate 2 through screws; first, insert the plug-in part 31 into the cap part 32 to form the main body part of the hinge piece 3. During the installation process, adjust the position of the plug-in part 31 in the cap part 32 according to actual needs to adapt to different installation angles or requirements. Ear parts 34 are provided on both the plug-in part 31 and the cap part 32. These ear parts are usually designed as protruding parts with holes for installing screws. After the hinge piece is fixed, the first guardrail plate 1 and the second guardrail plate 2 can be flexibly rotated and folded through the hinge piece 3. Since the hinge piece adopts a split design and is easy to disassemble and replace, in the process of long-term use, if damage or wear occurs, the split design can facilitate the maintenance or replacement work.

[0035] Specifically, there are two semi-circular chucks 3111 that are symmetrically arranged on the plug 31 and can approach or move away from each other. The two semi-circular chucks 3111 form a mushroom-shaped pin rod 311. At the end of the cap 32 away from the plug 31, a locking groove 321 is provided. The outer diameter of the pin rod 311 is slightly larger than the inner diameter of the cap 32. A button 33 that moves closer to or away from the pin rod 311 and fits with the end of the pin rod 311 is movably connected in the locking groove 321. The button 33 is used to squeeze the two semi-circular chucks 3111 to make them approach each other so as to disengage from the locking groove 321. When the plug 31 is inserted into the cap 32, the mushroom-shaped pin rod 311 is composed of two symmetrically arranged semi-circular chucks 3111. Because its outer diameter is slightly larger than the inner diameter of the cap 32, it will be slightly deformed under a certain extrusion until the pin rod 311 completely enters the locking groove 321 of the cap 32. At this time, the two semi-circular chucks 3111 return to their original state, and their outer surfaces are in close contact with the inner wall of the locking groove 321, forming a locked state, ensuring the stable and reliable connection between the plug 31 and the cap 32. When it is necessary to disassemble the hinge, press the button 33. The button 33 is movably connected in the locking groove 321 and is designed with a contact surface that fits with the end of the pin rod 311. As the button 33 is squeezed and moves towards the pin rod 311, its contact surface will apply an inward squeezing force to the two semi-circular chucks 3111, making the two semi-circular chucks 3111 approach each other and deform, thereby reducing their outer diameter. When the outer diameter of the two semi-circular chucks 3111 is reduced enough to pass through the opening of the locking groove 321, the plug 31 can be smoothly pulled out from the cap 32 to achieve unlocking and separation.

[0036] Embodiment 2

[0037] Different from Embodiment 1, in construction environments of different sizes, it is still necessary to customize the lengths of the first guardrail plate 1 and the second guardrail plate 2 according to the on-site dimensions, which is quite costly and affects the reuse rate. Therefore, as Figure 4 shown, a spliceable splicing guardrail plate 6 is provided between the first guardrail plate 1 and the second guardrail plate 2. Two juxtaposed plugs 31 and two juxtaposed caps 32 are respectively installed at both ends of the splicing guardrail plate 6.

[0038] During installation, only need to insert the plug 31 at one end of the splicing guardrail plate 6 into the cap 32 on the adjacent guardrail plate, and achieve a stable connection through the locking mechanism of the mushroom-shaped pin rod 311 and the locking groove 321. Similarly, the other end of the splicing guardrail plate 6 is also connected to another guardrail plate in the same way. By increasing or decreasing the number of splicing guardrail plates 6, the length of the entire guardrail structure can be flexibly adjusted to adapt to construction environments of different sizes. This design makes the guardrail structure no longer limited by guardrail plates of fixed length, improving its adaptability and flexibility.

[0039] As described above, it is only the preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, making equivalent substitutions or changes should be covered within the protection scope of the present application.
