Traditional fixed fencing is often standardized, difficult to adjust once fixed, and its height cannot be controlled, making it challenging to adapt to different floors and construction needs. This is particularly evident when site layouts require frequent changes.

[0003] Chinese utility model patent CN204676918U discloses an edge protection railing, comprising a protective steel pipe horizontally positioned between two reinforced concrete columns and a vertical post positioned between the two reinforced concrete columns; one end of the protective steel pipe is fixedly connected to one reinforced concrete column, and the other end of the protective steel pipe is fixedly connected to the other reinforced concrete column; the reinforced concrete column is provided with a steel sleeve for the protective steel pipe to be fitted onto, and a flat steel bar perpendicular to the steel sleeve and fixed to the reinforced concrete column; the post is fitted close to the protective steel pipe and connected to the protective steel pipe by fasteners, and one bottom end of the post is connected to an angle steel fixed to the ground.

[0004] The existing edge protection railing is installed on a reinforced concrete column. The number and height of protective steel pipes need to be adjusted according to protection requirements, resulting in poor adjustability. It also lacks protection against the frequent risk of falling objects from heights at construction sites. Therefore, there is a need for a prefabricated adjustable edge protection device that can solve the problems of poor adjustability and inability to prevent falling objects from heights in existing edge protection railings. Summary of the Invention

[0005] The purpose of this utility model is to provide a prefabricated adjustable edge protection device, which can solve the problems of poor adjustment flexibility and inability to prevent the risk of falling objects from heights in the existing edge protection railings.

[0006] This utility model is implemented as follows:

[0007] An adjustable prefabricated edge protection device includes a protective sliding rod, fasteners, a base, prefabricated railing bodies, and safety net hooks. The base is fixedly installed at the bottom of the protective sliding rod, allowing the protective sliding rod to be fixedly installed on the ground. A pair of protective sliding rods are arranged vertically at intervals at the edge. A sliding groove is formed on the protective sliding rod along its length. Several sets of prefabricated railing bodies are adjustablely installed between a pair of protective sliding rods through the sliding groove and are fastened to the pair of protective sliding rods with fasteners. Several safety net hooks are installed on the protective sliding rods, and the safety net is stretched to the outdoor side of the prefabricated railing body through the safety net hooks.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Please see the appendix Figure 1 An adjustable prefabricated edge protection device includes a protective sliding rod 1, fasteners 2, a base 3, prefabricated railing bodies 4, and safety net hooks 5. The base 3 is fixedly installed at the bottom of the protective sliding rod 1, so that the protective sliding rod 1 can be fixedly installed on the ground via the base 3 and fasteners 31, and a pair of protective sliding rods 1 are arranged vertically at intervals at the edge. A sliding groove (not shown in the figure) is formed on the protective sliding rod 1 along the length direction of the protective sliding rod 1. Several sets of prefabricated railing bodies 4 are adjustablely installed between a pair of protective sliding rods 1 through the sliding groove and are fastened to a pair of protective sliding rods 1 by fasteners 2. Several safety net hooks 5 are installed on the protective sliding rod 1, and the safety net is stretched to the outdoor side of the prefabricated railing body 4 through the safety net hooks 5.

[0021] The height of the protective sliding bar 1 can be adaptively adjusted according to the required protection height. The prefabricated railing body 4 can be standardized in design. One or more sets of prefabricated railing bodies 4 are vertically installed between a pair of protective sliding bars 1 to meet the protection requirements. The sliding groove allows for vertical adjustment of the installation height of each set of prefabricated railing bodies 4 to achieve optimal protection. It also facilitates the fixing of the ends of the prefabricated railing bodies 4 to the protective sliding bars 1 using fasteners 2, forming a unified edge protection structure. One or more fasteners 2 can be provided to ensure installation firmness.

[0022] The installation of safety net hooks 5 facilitates the tensioning and suspension of the safety net. The safety net is installed and suspended using conventional construction methods, a standard procedure in this field, and the installation process will not be detailed here. The tensioning and suspension of the safety net prevents falling objects from near edges, ensuring construction safety. The specifications and model of the safety net hooks 5 can be selected adaptably according to the installation requirements of the suspended safety net.

[0023] Preferably, the base 3 can be made of thick steel plate, and the protective slide rod 1 can be made of square steel tube. The specifications of the square steel tube can be selected according to actual usage requirements. The lower end of the protective slide rod 1 is welded and fixed to the center of the base 3, and fixing parts 31 are set at equal intervals around the protective slide rod 1 on the base 3. The base 3 has a large contact area with the ground, which facilitates the stable installation of the base 3 on the ground by fixing bolts and other fixing parts 31, thereby ensuring the installation stability and protective effectiveness of the entire device.

[0024] Depending on the requirements such as the protection length of the edge, multiple sets of the prefabricated adjustable edge protection devices of this utility model can also be installed sequentially along the edge.

[0025] Please see the appendix Figure 1 and attached Figure 2 The prefabricated railing body 4 includes railing units 41 and railing frames 42. The top and bottom ends of the railing unit 41 are provided with slot holes 43, so that two adjacent railing units 41 can be spliced ​​together by a plug plate 44 with slot holes 43 and a pin 45. The railing frame 42 has a C-shaped structure, and the top and bottom ends of the railing frame 42 are provided with slot holes 43, so that the railing frame 42 can be spliced ​​to the end of the railing unit 41 by a plug plate 44 with slot holes 43 and a pin 45. Several sets of railing units 41 are assembled between a pair of oppositely arranged railing frames 42.

[0026] The railing unit 41 and railing frame 42 can be manufactured in a standardized manner. The number of railing units 41 can be adjusted according to the protection length requirements, i.e., the spacing between a pair of protective sliding bars 1. A pair of railing frames 42 are connected to the railing units 41 located at both ends of the prefabricated railing body 4. The assembly is highly flexible and adaptable to different edge structures.

[0027] With the slot hole 43, the plug plate 44 and the pin 45, simply inserting the pin 45 into the slot hole 43 makes the splicing and assembly of two adjacent sets of railing units 41 and the splicing and assembly of railing units 41 and railing frame 42 more convenient, faster and easier to disassemble.

[0028] The railing frame 42 has a threaded hole (not shown in the figure) in the middle. One end of the fastener 2 passes through the sliding groove and is screwed into the threaded hole, so that the middle part of the railing frame 42 is fixed on the inner side of the protective slide bar 1 (the side of the pair of protective slide bars 1 facing each other is the inner side, and the side of the pair of protective slide bars 1 facing away from each other is the outer side). The other end of the fastener 2 is pressed against the outer side of the protective slide bar 1.

[0029] The threaded holes on the railing frame 42 facilitate the screwing and installation of the fasteners 2, allowing for quick and convenient assembly and disassembly, and ensuring an efficient and secure connection between the railing frame 42 and the protective sliding rod 1. Preferably, the railing frame 42 can be made of square steel tubing to effectively fit the inner side of the protective sliding rod 1; simultaneously, the width of the railing frame 42 should be greater than the width of the sliding groove to ensure a tight fit of the railing frame 42 on the inner side of the protective sliding rod 1. The fasteners 2 can be fastening bolts, and the bolt head size of the fasteners 2 should be greater than the width of the sliding groove to ensure a tight fit of the bolt head of the fasteners 2 on the outer side of the protective sliding rod 1.

[0030] Please see the appendix Figure 2 The railing unit 41 includes a top plate 411, a bottom plate 412, and vertical railings 413. An adjustment groove 414 is formed on the top plate 411 along its length. The upper end of the vertical railing 413 is adjustablely connected to the top plate 411 through the adjustment groove 414, and the lower end of the vertical railing 413 abuts against the upper surface of the bottom plate 412, so that several vertical railings 413 form a vertical protective structure with intervals between a pair of protective sliding rods 1.

[0031] The horizontally arranged top plate 411 and bottom plate 412, and the vertically arranged vertical railings 413 can form horizontal and vertical protection at the edge, ensuring the protective effect. By adjusting the arrangement of the through grooves 414, the spacing of the vertical railings 413 can be moved and adjusted to achieve the best protective effect and prevent objects from falling at the edge.

[0032] Please see the appendix Figure 2 The top of the vertical railing 413 has a protrusion forming a screw 415. The screw 415 passes through the adjustment slot 414. The locking nut 416 is screwed onto the screw 415 and pressed against the upper surface of the top plate 411. The top of the vertical railing 413 is pressed against the lower surface of the top plate 411.

[0033] Preferably, the top plate 411, bottom plate 412, and vertical railing 413 can be made of square steel tubing, and their specifications can be adjusted according to actual usage requirements. The width of the adjusting groove 414 is slightly larger than the diameter of the screw 415 but smaller than the width of the vertical railing 413, to ensure that the upper end of the vertical railing 413 can be locked and fixed to the top plate 411 by the screw 415 and the locking nut 416. The length of the vertical railing 413 is consistent with the distance between the bottom plate 412 and the top plate 411, so that the lower end of the vertical railing 413 contacts the bottom plate 412 to ensure the protective effect.

[0034] Please see the appendix Figure 1 and attached Figure 2 The assembly method of this utility model is as follows:

[0035] The protective sliding bar 1 is fixedly installed on the ground using the fixing bolts (fixtures 31) on the base 3. The spacing and height of the pair of protective sliding bars 1 can be adjusted according to the protection requirements. Based on the spacing of the pair of protective sliding bars 1, select the appropriate number of railing units 41 and a pair of railing frames 42. Figure 1 and attached Figure 2 The image shows the installation of three sets of railing units 41.

[0036] The slot holes 43 on the top of two adjacent sets of railing units 41 are aligned with the two slot holes 43 on the connector plate 44. A pin 45 is inserted into the slot hole 43, connecting the tops of the two adjacent sets of railing units 41 together. Similarly, the bottoms of the two adjacent sets of railing units 41 are connected together. Connectors 44 and pins 45 can be provided on both the front and back of adjacent sets of railing units 41 to ensure the reliability of the railing unit 41 assembly. All railing units 41 are connected sequentially using the above method; further details are omitted here.

Similarly, connect the bottom of the end railing unit 41 with the bottom of the railing frame 42. A pair of railing frames 42 are installed on the railing units 41 at both ends using the same installation method to form an assembled railing body 4 that meets the protection length requirements.

[0038] According to the protection requirements, the adjusting vertical railing 413 is moved along the adjusting groove 414 to ensure that the spacing between two adjacent vertical railings 413 meets the protection requirements. The locking nut 416 is screwed onto the screw rod 415 and tightened against the upper surface of the top plate 411, with the top of the vertical railing 413 pressing against the lower surface of the top plate 411. The number of vertical railings 413 can be adjusted adaptively according to the spacing of the vertical railings 413.

[0039] According to the required protection height, assemble the corresponding number of prefabricated railing bodies 4. All prefabricated railing bodies 4 are assembled in the same way, which will not be described in detail here.

[0040] The prefabricated railing body 4 is snapped between a pair of protective sliding rods 1. The prefabricated railing body 4 is then slid up and down along the sliding groove to adjust its position, ensuring that each prefabricated railing body 4 is vertically and evenly installed to achieve effective protection. Figure 1The diagram shows the installation of two sets of prefabricated railing bodies 4. Fasteners 2 are passed through sliding grooves and screwed into threaded holes in the center of the railing frame 42 of the prefabricated railing body 4. The fasteners 2 and the railing frame 42 are respectively pressed against the outer and inner sides of the protective sliding rods 1. Both ends of the prefabricated railing body 4 are connected and fixed to a pair of protective sliding rods 1 in the same manner, ensuring the reliable installation of the prefabricated railing body 4.

[0041] The top plate 411, bottom plate 412, and vertical railing 413 provide edge protection. Safety netting is tensioned on the outdoor side of the prefabricated railing body 4 via safety net hooks 5, preventing falling objects from the edge and improving construction safety.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
