Description

Technical Field

[0001] This utility model relates to the field of building protection technology, and in particular to an adaptive non-destructive fixing device for edge protection. Background Technology

[0002] During construction, safety protection of building edges (such as floor slab edges, balcony edges, staircase edges) and opening areas is a key aspect of ensuring the safety of construction workers and is also one of the core contents of construction site safety management.

[0003] Traditional edge protection often uses steel pipes and fasteners for installation, typically fixed by pre-embedded reinforcing bars followed by welding or by drilling holes in floor slabs or beams and then securing them with expansion bolts. These welding and drilling methods essentially compromise the building structure to achieve stability. Pre-embedded welding leaves permanent weld points on the structural surface, while drilling creates holes that are difficult to repair. This not only compromises the integrity of the concrete structure and reduces its load-bearing capacity but also hinders subsequent wall and floor finishing, making it particularly unsuitable for areas with weak or delicate components such as precast composite slabs or steel-structured floor slabs. Furthermore, once the installation location is determined, this type of fixing method cannot be adjusted, offering extremely poor flexibility and making it difficult to adapt to changing construction conditions.

[0004] Therefore, there is a need for an edge protection fixing device that does not damage the building structure, adapts to different installation conditions, is easy to assemble and disassemble, and is reusable, in order to solve many of the pain points of existing technologies. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an adaptive non-destructive fixing device for edge protection.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adaptive non-destructive fixing device for edge protection, including a fixing rod, a guardrail connecting mechanism provided at one end of the fixing rod, an adaptive clamping mechanism slidably provided on the fixing rod, the guardrail connecting mechanism, the adaptive clamping mechanism and the fixing rod forming an F-shaped structure, and the bayonet of the F-shaped structure being used to clamp onto the building, and also including a locking mechanism for fixing the adaptive clamping mechanism and the fixing rod.

[0007] By adopting the above technical solution, a fixed rod, a guardrail connecting mechanism, and an adaptive clamping mechanism are set up to form an F-shaped structure. The mechanical clamping principle of the F-shaped structure is used to achieve fixation. The entire process does not require destructive operations such as welding, drilling, or pre-embedding on the building structure, avoiding permanent damage to concrete, steel structure and other components caused by traditional fixing methods, and maintaining the integrity and load-bearing safety of the building structure. The adaptive clamping mechanism slides along the fixed rod to adjust its position and locks it in place with the locking mechanism. It can flexibly adapt to various edge conditions such as walls, floor slab edges, parapet walls, and columns of different thicknesses. Installation and disassembly are very convenient. All components can be completely recycled and reused in multiple construction projects, reducing material waste.

[0008] Furthermore, the guardrail connecting mechanism includes a square tube, the length direction of which is perpendicular to the fixed rod and one side of the tube wall is fixedly connected to the end of the fixed rod. A hole is opened on the tube wall that is not connected to the end of the fixed rod, and a nut is provided at the opening. A locking screw is screwed on the nut, and the inner end of the locking screw is located inside the cavity of the square tube.

[0009] By adopting the above technical solution, a square tube is set up and vertically fixed to a fixing rod to form an upper wing plate with an F-shaped structure. Nuts and locking screws are then set up. Various guardrails of different diameters can be adapted inside the square tube. The guardrails are tightened by screwing the locking screws, thereby achieving reliable fixation of the guardrails inside the square tube and improving the versatility of the guardrail connection mechanism.

[0010] Furthermore, a first anti-slip rubber pad is provided on the side wall of the square tube connected to the fixed rod.

[0011] By adopting the above technical solution and setting a first anti-slip rubber pad, the pressure of the square tube on the building surface can be effectively buffered when the square tube comes into contact with the building component, preventing the square tube from scratching or squeezing the building component and causing damage such as scratches and dents on the component surface. In addition, the first anti-slip rubber pad can increase the friction between the square tube and the building component surface, reduce the relative sliding between the square tube and the building structure, and further improve the overall stability.

[0012] Furthermore, the adaptive clamping mechanism includes a sliding sleeve and a clamping angle steel. The sliding sleeve is slidably mounted on the fixed rod. One side of the clamping angle steel is fixed to the side wall of the sliding sleeve as a fixed side, and the other side is arranged as a clamping side on the side of the fixed side away from the guardrail connecting mechanism.

[0013] By adopting the above technical solution, the clamping angle steel is moved on the fixed rod by the sliding sleeve, thereby flexibly adjusting the distance between the clamping angle steel and the guardrail connection mechanism according to the different thicknesses of building components such as walls and columns, so that the F-shaped structure can accurately adapt to building components of different thicknesses.

[0014] Furthermore, a second anti-slip rubber pad is arranged on the inner side of both the fixed side and the clamping side of the clamping angle steel.

[0015] By adopting the above technical solution and setting a second anti-slip rubber pad, the pressure of the clamping angle steel on the building surface can be effectively buffered when the clamping angle steel comes into contact with the building component, preventing the clamping angle steel from scratching or squeezing the building component and causing damage such as scratches and dents on the component surface. In addition, the second anti-slip rubber pad can increase the friction between the clamping angle steel and the building component surface, reduce the relative sliding between the clamping angle steel and the building structure, and further improve the overall stability.

[0016] Furthermore, the fixed rod is provided with a plurality of positioning holes at intervals along its length, and the sliding sleeve is provided with a plurality of limiting holes at intervals along its length. The spacing between the plurality of positioning holes is the same as the spacing between the plurality of limiting holes. The locking mechanism includes a plurality of L-shaped rods, which are used to insert into the corresponding limiting holes and positioning holes to fix the sliding sleeve and the fixed rod.

[0017] By adopting the above technical solution, the positioning hole and the limiting hole are spaced at the same distance, so that after the sliding sleeve slides to the appropriate position on the fixed rod, the corresponding positioning hole and limiting hole can be quickly found. The sliding sleeve and the fixed rod can be fixed by inserting the L-shaped rod, without the need for complex operations such as tightening bolts for positioning and locking. The operation is simple and quick, which greatly shortens the installation time of the device and improves the construction efficiency of edge protection.

[0018] In summary, this utility model has the following beneficial effects: In this application, by setting a fixed rod, a guardrail connecting mechanism, and an adaptive clamping mechanism to form an F-shaped structure, the mechanical clamping principle of the F-shaped structure is used to achieve fixation. The entire process does not require destructive operations such as welding, drilling, and pre-embedding on the building structure, avoiding permanent damage to concrete, steel structure and other components caused by traditional fixing methods, and maintaining the integrity and load-bearing safety of the building structure. The adaptive clamping mechanism slides along the fixed rod to adjust its position and locks it in conjunction with the locking mechanism. It can flexibly adapt to various edge conditions such as walls, floor slab edges, parapet walls, and columns of different thicknesses. Installation and disassembly are very convenient. All components can be completely recycled and reused in multiple construction projects, reducing material waste. Attached Figure Description

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] like Figure 1-4 As shown in the illustration, this application discloses an adaptive non-destructive fixing device for edge protection, including a fixing rod 10, a guardrail connecting mechanism 20, an adaptive clamping mechanism 30, and a locking mechanism 40. The guardrail connecting mechanism 20 is disposed at one end of the fixing rod 10, the adaptive clamping mechanism 30 is slidably disposed on the fixing rod 10, and the locking mechanism 40 is used to fix the adaptive clamping mechanism 30 to the fixing rod 10. The guardrail connecting mechanism 20, the adaptive clamping mechanism 30, and the fixing rod 10 together form an F-shaped structure, with the fixing rod 10 as the web, the guardrail connecting mechanism 20 as the upper wing, and the adaptive clamping mechanism 30 as the lower wing. An F-shaped bayonet is formed between the guardrail connecting mechanism 20 and the adaptive clamping mechanism 30 for fixing to the building. This utilizes the mechanical clamping principle of the F-shaped bayonet to achieve fixing, eliminating the need for destructive operations such as welding, drilling, and pre-embedding on the building structure throughout the process. This avoids permanent damage to concrete, steel structures, and other components caused by traditional fixing methods, maintaining the integrity and load-bearing safety of the building structure. By adjusting the position of the adaptive clamping mechanism 30 along the fixed rod 10 and locking it with the locking mechanism 40, the size of the F-shaped structure can be adjusted. It can flexibly adapt to various edge conditions such as walls, floor slab edges, parapet walls, and columns of different thicknesses. Installation and disassembly are very convenient. All components can be completely recycled and reused in multiple construction projects, reducing material waste.

[0023] Specifically, the guardrail connection mechanism 20 includes a square tube 21, the length of which is perpendicular to the fixed rod 10, and one side of the tube wall is fixedly connected to the end of the fixed rod 10. The square tube 21 forms an upper wing plate of an F-shaped structure, which serves as the mounting carrier for the guardrail, ensuring the verticality and rigidity of the connection between the guardrail and the fixing device, and preventing the guardrail from tilting or swaying due to instability of the mounting carrier. A first anti-slip rubber pad 24 is provided on the side wall of the square tube 21 connected to the fixed rod 10. This effectively buffers the pressure of the square tube 21 on the building surface when it comes into contact with the building component, preventing the square tube 21 from scratching or squeezing the building component and causing scratches, dents, or other damage to the component surface. In addition, the first anti-slip rubber pad 24 increases the friction between the square tube 21 and the surface of the building component, reduces the relative sliding between the square tube 21 and the building structure, and further improves the overall stability.

[0024] A hole is made in one of the tube walls of the square tube 21 that is not connected to the end of the fixing rod 10, and a nut 22 is installed at the hole. A locking screw 23 is screwed onto the nut 22, and the inner end of the locking screw 23 is located inside the cavity of the square tube 21. The square tube 21 can accommodate guardrails of various diameters. By screwing the locking screw 23, the guardrails are secured, thereby achieving reliable fixation of the guardrails inside the square tube 21 and improving the versatility of the guardrail connection mechanism 20.

[0025] The adaptive clamping mechanism 30 includes a sliding sleeve 31 and a clamping angle steel 32. The sliding sleeve 31 is slidably mounted on the fixed rod 10, thereby driving the adaptive clamping mechanism 30 to slide on the fixed rod 10. It can flexibly adjust the distance between the clamping angle steel 32 and the guardrail connecting mechanism 20 according to the different thicknesses of building components such as walls and columns. This allows the F-shaped clamping structure to accurately adapt to building components of different thicknesses, eliminating the need to customize adaptive clamping mechanisms 30 of different specifications for components of different thicknesses, greatly improving the adaptability and versatility of the device to different construction conditions. One side of the clamping angle steel 32 is fixed to the side wall of the sliding sleeve 31 as a fixed side, while the other side is arranged as a clamping side on the side away from the guardrail connecting mechanism 20, forming the lower wing plate of the F-shaped structure. A second anti-slip rubber pad 33 is arranged on the inner side of both the fixed side and the clamping side of the clamping angle steel 32. This effectively cushions the pressure of the angle steel 32 on the building surface when it comes into contact with the building component, preventing scratches, dents, and other damage caused by the angle steel 32 scraping or squeezing the building component. Furthermore, the second anti-slip rubber pad 33 increases the friction between the angle steel 32 and the building component surface, reducing relative sliding between the angle steel 32 and the building structure, further enhancing overall stability.

[0026] A plurality of positioning holes 11 are spaced apart along the length of the fixed rod 10, and a plurality of limiting holes 34 are spaced apart along the length of the sliding sleeve 31. The spacing between the positioning holes 11 is the same as the spacing between the limiting holes 34. The locking mechanism 40 includes a plurality of L-shaped rods 41, which are inserted into the corresponding limiting holes 34 and positioning holes 11 to fix the sliding sleeve 31 to the fixed rod 10. The spacing between the positioning holes 11 and the limiting holes 34 is consistent, so that after the sliding sleeve 31 slides to a suitable position on the fixed rod 10, it can quickly find the corresponding positioning holes 11 and limiting holes 34. The fixing of the sliding sleeve 31 to the fixed rod 10 can be completed by inserting the L-shaped rod, without the need for complex operations such as tightening bolts for positioning and locking. The operation is simple and quick, greatly shortening the installation time of the device and improving the construction efficiency of edge protection.

[0027] The working principle of the adaptive non-destructive fixing device for edge protection in this embodiment is as follows: First, the sliding sleeve 31 drives the clamping angle steel 32 to move away from the square tube 21. When the distance is greater than the thickness of the building component, the device is clamped on the building component. The side of the square tube 21 equipped with the first anti-slip rubber pad 24 is close to the side of the building component. Then, the sliding sleeve 31 is driven to drive the clamping angle steel 32 to move towards the square tube 21, so that the clamping angle steel 32 presses against the side of the building component corresponding to the square tube 21. After the clamping angle steel 32 and the square tube 21 are clamped on the building component, the L-shaped rod 41 is inserted into the positioning hole 11 and the limiting hole 34 to achieve fixation. Then, the guardrail is inserted into the square tube 21, and the locking screw 23 is screwed down so that the inner end of the locking screw 23 presses against the guardrail to achieve fixation of the guardrail. When disassembly is required, simply loosen the locking screw 23 to pull out the guardrail, then pull out the L-shaped rod 41 and slide the sliding sleeve 31 to remove the fixing device from the building component. The entire installation and disassembly process is simple and convenient, will not damage the building component, and the disassembled fixing device can be reused.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
