Description

Technical Field

[0001] This application relates to the field of protective fencing technology, and more particularly to a splicing frame for protective fencing. Background Technology

[0002] At construction sites, road repair sites, and other engineering projects, fencing is a common and important isolation and protection facility. The traditional method of installing the fencing frame is to fix the connection between the two uprights and the two crossbeams by welding. However, the welding process is relatively complicated. In harsh environments or when the fencing frame is subjected to a large load, the welds between the uprights and the crossbeams are prone to cracking, which can lead to the breakage of the two uprights and the crossbeams, resulting in an unstable overall structure. Summary of the Invention

[0003] In view of this, this application proposes a splicing frame for protective fencing, comprising: two vertical beams and two horizontal beams;

[0004] The two vertical beams are parallel to each other in length, and the two horizontal beams are placed between the two vertical beams and are perpendicular to each other;

[0005] Each crossbeam has a fixing component at both ends, and the crossbeam is detachably connected to the vertical beam through the fixing component;

[0006] The fixing assembly includes: a first bolt and a first nut; a connecting hole is provided on the side wall of the vertical beam, one end of the first bolt passes through the side wall of the horizontal beam and is threadedly connected to the first nut, the first nut is fixedly connected to the horizontal beam, and the other end of the first bolt is inserted into the cavity of the vertical beam through the connecting hole;

[0007] Each vertical beam includes: a first column and a second column that are detachably connected; one end of the first column is provided with a tenon; the second column is provided with a cavity with an open end, and the tenon of the first column is inserted into the cavity of the second column through the opening and is fixedly connected to the second column by a locking part.

[0008] In one possible implementation, the locking part includes a second bolt and a second nut; the second nut is fixedly disposed on the inner side wall of the tenon, the second bolt passes through the second post and the tenon in sequence, and the second nut is sleeved on the second bolt, which is suitable for fixing the tenon and the second post together.

[0009] In one possible implementation, the first post, the second post, and the main body of the tenon are all rectangular tubular structures.

[0010] In one possible implementation, the outer diameter of the tenon is smaller than the inner diameter of the second post, and the inner diameter of the second post is the same as the inner diameter of the first post.

[0011] In one possible implementation, mounting holes are provided on the side wall of the vertical beam, with the mounting holes and connection holes positioned opposite each other.

[0012] In one possible implementation, both the connecting holes and mounting holes are gourd-shaped, with the top being larger than the bottom.

[0013] Beneficial effects of this application

[0014] By setting up a fixing component, the threaded engagement of the first bolt and the first nut of the fixing component can provide a strong fastening force, which not only improves the stability and safety of the splicing frame for the protective fence, but also makes the installation and disassembly of the entire frame structure more convenient and quick due to the detachability of the first bolt and the first nut.

[0015] The first and second columns are connected by a mortise and tenon joint and then secured again by a locking mechanism. The mortise and tenon joint provides initial positioning and connection, increasing the stability and accuracy of the connection between the first and second columns. On this basis, the locking mechanism further strengthens the connection between the first and second columns. Compared with the traditional method, the connection between the first and second columns is not only more convenient and efficient to install and disassemble, reducing the time and labor costs required for installation and disassembly, but also avoids damage to the vertical beam structure and improves the reusability of materials.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0029] This application proposes a splicing frame for protective fencing, such as Figures 1 to 6As shown, it includes: two vertical beams 100 and two horizontal beams 200; the length directions of the two vertical beams 100 are parallel to each other, and the two horizontal beams 200 are disposed between the two vertical beams 100, with the length directions of the vertical beams 100 and the length directions of the horizontal beams 200 being perpendicular to each other; each horizontal beam 200 has a fixing component 300 at both ends, and the horizontal beam 200 is detachably connected to the vertical beam 100 through the fixing component 300; the fixing component 300 includes: a first bolt 310 and a first nut 320; a connecting hole 140 is opened on the side wall of the vertical beam 100, and one end of the first bolt 310 passes through it. The side wall of the crossbeam 200 is threadedly connected to the first nut 320, which is fixedly connected to the crossbeam 200. The other end of the first bolt 310 is inserted into the cavity of the vertical beam 100 through the connecting hole 140. Each vertical beam 100 includes a first column 110 and a second column 120 that are detachably connected. One end of the first column 110 is provided with a tenon 130. The second column 120 is provided with a cavity with one end open. The tenon 130 of the first column 110 is inserted into the cavity of the second column 120 through the opening and is fixedly connected to the second column 120 through a locking part.

[0030] It should be noted here that, as Figure 1 As shown, the two parallel vertical beams 100 can evenly distribute the vertical load, improving the load-bearing capacity of the vertical beams 100. The horizontal beams 200 are suitable for providing horizontal support, preventing the vertical beams 100 from deforming or tilting due to excessive force. The two vertical beams 100 and the two horizontal beams 200 are connected end to end to form a rectangular frame structure. The rectangular frame structure can effectively resist external pressure and prevent the frame from overturning due to wind, human impact, or other factors, ensuring the stability and load-bearing capacity of the overall frame structure. The fixing component 300 is suitable for ensuring a tight connection between the vertical and horizontal beams 200 and the vertical beams 100, avoiding breakage or deformation at the connection between the horizontal beams 200 and the vertical beams 100 due to wind or other external forces.

[0031] like Figures 3 to 5 As shown, the first nut 320 is fixedly installed at both ends of the crossbeam 200, with the screw hole of the first nut 320 facing the direction of the vertical beam 100. The screw of the first bolt 310 passes through the side wall of the crossbeam 200 and is pre-connected to the first nut 320. The bolt head of the first bolt 310 passes through the connection hole 140 of the vertical beam 100 and enters the cavity of the vertical beam 100. By turning the first bolt 310, the screw of the first bolt 310 screws in and out of the screw hole of the first nut 320, thereby locking the crossbeam 200 onto the vertical beam 100. By setting the fixing component 300, the threaded engagement of the first bolt 310 and the first nut 320 of the fixing component 300 can provide a strong fastening force, which not only improves the stability and safety of the splicing frame for the protective fence, but also makes the installation and disassembly of the entire frame structure more convenient and quick due to the detachability of the first bolt 310 and the first nut 320.

[0032] like Figure 2 , Figure 6 As shown, the detachable connection design between the first column 110 and the second column 120 makes the assembly and disassembly of the frame more convenient and quick. This design allows construction personnel to adjust, replace, repair, and transport the frame as needed, improving construction efficiency and facilitating handling. The tenon 130 is fixedly set at one end of the first column 110, and the outer contour of the tenon 130 matches the opening of the second column 120. The tenon 130 of the first column 110 is inserted into the cavity of the second column 120 through the opening. The matching design of the tenon 130 and the cavity makes the connection between the first column 110 and the second column 120 tighter and more stable. The locking part is suitable for providing additional fastening force, thereby firmly locking the tenon 130 of the first column 110 into the cavity of the second column 120. By setting the locking part, not only is the stability between the two columns ensured, but also the detachable connection between the first column 110 and the second column 120 is realized.

[0033] The first column 110 and the second column 120 are connected by a mortise and tenon structure and then fixed again by a locking part. The mortise and tenon structure provides initial positioning and connection, increasing the stability and accuracy of the connection between the first column 110 and the second column 120. On this basis, the locking part further strengthens the firmness of the connection between the first column 110 and the second column 120. Compared with the traditional method, the connection method between the first column 110 and the second column 120 is not only more convenient and efficient to install and disassemble, reducing the time and labor costs required for installation and disassembly, but also avoids damage to the vertical beam 100 structure and improves the reusability of materials.

[0034] Furthermore, the first bolt 310 and the first nut 320 both adopt the existing technology of M8×35 internal hexagon screws and nuts.

[0035] In one possible implementation, the locking part includes a second bolt 410 and a second nut 420; the second nut 420 is fixedly disposed on the inner side wall of the tenon 130, the second bolt 410 passes through the second column 120 and the tenon 130 in sequence, and the second nut 420 is sleeved on the second bolt 410, which is suitable for fixing the tenon 130 and the second column 120 together.

[0036] It should be noted here that, as Figure 2 , Figure 6As shown, a first through hole 131 is provided on the outer wall of the tenon 130. The size of the first through hole 131 matches the outer contour of the second nut 420. The second nut 420 is fixedly installed in the cavity of the tenon 130, and the screw hole of the second nut 420 communicates with the first through hole 131. A second through hole 210 is provided on the outer wall of the second column 120. The second through hole 210 corresponds to the first through hole 131. The second bolt 410 passes through the second through hole 210 and the first through hole 131 in sequence and is threadedly connected to the second nut 420. By tightening the second bolt 410, The second bolt 410 can be screwed in and out of the screw hole of the second nut 420, thereby locking the tenon 130 into the cavity of the second column 120. The design of the locking part and the tenon 130 cooperating with each other makes the installation and disassembly of the first column 110 and the second column 120 more convenient and quick. When the first column 110 needs to be repaired or replaced, the second bolt 410 can be rotated in the opposite direction, thereby allowing the second bolt 410 to be pulled out from the second column 120 and the tenon 130, thus realizing the disassembly of the first column 110 and the second column 120, improving construction efficiency.

[0037] Furthermore, at least one first through hole 131 is provided, and correspondingly, at least one second through hole 210 is provided.

[0038] Preferably, there are two first through holes 131, which are arranged along the length of the tenon. Correspondingly, there are two second through holes 210, which are arranged along the length of the second post 120. The first through holes 131 and the second through holes 210 correspond one-to-one.

[0039] Preferably, the second bolt 410 and the second nut 420 are both M8×20 internal hex bolts and nuts in the prior art.

[0040] In one possible implementation, such as Figure 2 As shown, the main bodies of the first column 110, the second column 120, and the tenon 130 are all rectangular tubular structures. It should be noted that the rectangular tubular structure reduces the weight of the first column 110, the second column 120, and the tenon 130, helping to reduce the burden on the foundation structure and lower installation costs. At the same time, the rectangular structure facilitates standardized manufacturing, making the installation and maintenance of the first column 110 and the second column 120 simpler and faster, reducing labor intensity and improving installation efficiency.

[0041] In one possible implementation, the outer diameter of the tenon 130 is smaller than the inner diameter of the second post 120, while the inner diameter of the first post 110 is the same as that of the second post 120. It should be noted that because the outer diameter of the tenon 130 is smaller than the inner diameter of the second post 120, the tenon 130 can be easily inserted into the cavity of the second post 120, thus connecting the first post 110 and the second post 120. This simplifies the installation and disassembly of the first post 110 and the second post 120, improving work efficiency. The fact that the inner diameters of the first post 110 and the second post 120 are the same allows for a more even distribution of force at the connection point, preventing damage caused by uneven force distribution and ensuring overall structural stability. Furthermore, the identical outer diameters of the first post 110 and the second post 120 eliminate the need for complex adjustments or alignment during assembly, simplifying the installation process and improving work efficiency.

[0042] Preferably, the difference between the inner diameter of the second post 120 and the outer diameter of the tenon 130 is 2mm. The 2mm gap allows the tenon 130 to be easily inserted into the opening of the second post without requiring excessive force or precision, thus simplifying the installation process.

[0043] In one possible implementation, such as Figures 2 to 4 As shown, both the connecting hole 140 and the mounting hole 141 are gourd-shaped, with the top being larger than the bottom. It should be noted here that... Figures 2 to 5 As shown, the first nut 320 is fixed at both ends of the crossbeam 200 by riveting. One end of the first bolt 310 is threadedly connected to the first nut 320. The size of the nut of the first bolt 310 is smaller than the size of the large hole of the mounting hole 141 but larger than the size of the small hole of the mounting hole 141. The nut of the first bolt 310 is inserted into the cavity of the vertical beam 100 through the large hole of the mounting hole 141. The larger upper part of the gourd-shaped mounting hole 141 provides sufficient space for the nut of the first bolt 310, making it easier for the first bolt 310 to be inserted into the interior of the vertical beam 100. The diameter of the screw 310 matches the size of the small hole in the mounting hole 141. The first bolt 310, which is inserted into the vertical beam 100, moves downward so that the screw of the first bolt 310 is embedded in the small hole in the mounting hole 141. By tightening the first bolt 310, the nut of the first bolt 310 can fit tightly against the inner wall of the vertical beam 100. The first bolt 310 and the first nut 320 cooperate to form a clamping force. The smaller lower part of the gourd-shaped mounting hole 141 prevents the nut of the first bolt 310 from falling out of the interior of the vertical beam 100, thus ensuring a stable connection between the cross beam 200 and the vertical beam 100.

[0044] In one possible implementation, such as Figures 3 to 5As shown, mounting holes 141 are provided on the side wall of the vertical beam 100, and the mounting holes 141 are arranged opposite to the connecting holes 140. It should be noted that the design of the mounting holes 141 allows workers to use installation tools to reach into the vertical beam 100 from the outside and install and tighten the first bolt 310 inserted into the vertical beam 100. This enables the installation or disassembly of the horizontal beam 200 and the vertical beam 100 without disassembling the horizontal beam 200 or other parts of the vertical beam 100, simplifying the installation process. The relative arrangement of the mounting holes 141 and the connecting holes 140 allows workers to quickly locate and install the first bolt 310 without spending a lot of time finding and calibrating the position of the first bolt 310, thus improving installation efficiency.

[0045] The protective fence to be installed in this application must be compatible with the splicing frame. The protective fence is installed on the inside of the splicing frame. The protective fence can be fixed to the horizontal beam 200 and the vertical beam 100 by welding, bolting, bonding, pull ring or other connection methods. This application does not limit the connection methods.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
