Description

Technical Field

[0001] This invention relates to the field of construction protection fencing technology, and in particular to a prefabricated, reusable, green construction protection fencing device for slopes. Background Technology

[0002] In the current field of infrastructure construction and ecological restoration projects, projects such as the construction of mountain highways, the ecological environment management of mines, the riverbank slope restoration, and the construction of urban building foundation pits will generate a large number of exposed slopes. During the slope construction process, in order to prevent the falling of slope debris, landslides, and the spread of construction dust, which threaten the safety of construction workers and the surrounding environment, it is necessary to set up protective barriers in the slope construction area.

[0003] Existing prefabricated fencing designed for flat construction, while reusable, suffers from several drawbacks due to its structural design being geared towards flat ground. Firstly, existing prefabricated fencing units are mostly rigidly connected, while slopes exhibit significant topographical undulations, both horizontally and vertically. Rigidly connected fencing units cannot adapt to these changes, leading to substantial internal stress at the joints. Over time, this can result in joint breakage and fencing collapse, compromising safety. Secondly, the back support structure of existing prefabricated fencing is typically of fixed length, making it impossible to adjust the support length according to the slope. To ensure stability during installation, extensive leveling and earthwork are required, increasing construction workload and costs while damaging existing vegetation and the ecosystem, thus failing to meet the requirements of ecological construction. Summary of the Invention

[0004] This invention solves the problems in related technologies by proposing a prefabricated, reusable green construction protective fence device for slopes, which solves the problems that existing construction protective fences cannot adapt to terrain changes and are cumbersome to construct.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a prefabricated reusable slope green construction protective enclosure device, comprising several sets of enclosure frames, which are connected to each other by universal components. Several sets of protective net frames are installed on the enclosure frames. The anti-slip net frames are fixedly connected to the enclosure frames by bolts. Two sets of angle seat shells are installed on the rear end face of the anti-slip net frames, and the head of the anti-slip net frames is detachably and rotatably connected to the angle seat shells. An adjustable extension bracket is slidably installed at the lower end of the angle seat shell, and a positioning component that locks with the adjustable extension bracket is provided in the angle seat shell. A slope fixing seat is rotatably installed at the lower end of the positioning component.

[0006] By adopting the above technical solution, multiple sets of fencing frames are spliced ​​together to form an integral fencing, meeting the protection needs of slopes of different lengths. The structure of the universal component connecting adjacent fencing frames allows for a certain angle of deflection between adjacent fencing frames, adapting to the undulations of the slope and avoiding the problem of easy breakage of rigid connections. The protective net frame is fixed to the fencing frame with bolts, making it easy to disassemble and assemble. Damaged frames can be replaced individually, reducing maintenance costs. The angle seat shell can drive the support structure to achieve angle adjustment, adapting to slopes with different inclination angles, ensuring that the protective surface fits the slope, and improving the protection effect. The adjustable extension bracket can adjust the support length and lock it with the positioning component, adapting to the installation needs of fencing with different slopes and heights. The slope fixing seat at the lower end can rotate to adjust the angle, ensuring that the fixing seat fits the slope completely, improving the stability of the support and preventing the fencing from shaking and collapsing.

[0007] As a preferred embodiment, the enclosure frame includes a frame and a cross-shaped central frame. The cross-shaped central frame is installed in the frame and its four ends are fixedly connected to the frame. Both the frame and the cross-shaped central frame are provided with connecting lugs for installing the protective net frame. The outer sides of the frame are also provided with positioning tube seats that are connected to the universal joint assembly. The positioning tube seats are integrally formed with the frame, and a long screw for rotating the universal joint assembly is inserted into the positioning tube seat. The lower end of the long screw is provided with a matching locking nut. Ground seats are provided on both sides of the lower end face of the frame, and the ground seats are rotatably connected to the frame.

[0008] By adopting the above technical solutions, the fence frame uses a frame structure combined with a cross-shaped central frame, resulting in high overall structural strength, light weight, and easy transportation and installation. The connecting ear plates facilitate the alignment and installation of the protective net frame, improving assembly efficiency. The positioning tube seat is integrally formed on the outside of the frame, ensuring high structural strength and preventing detachment. The long screw and locking nut work together to install and fix the universal components, making assembly and disassembly convenient. The ground seat at the lower end can be rotated to adjust the angle, ensuring that the bottom of the fence frame fits snugly against the ground even on uneven slopes, thus improving the overall stability of the fence frame.

[0009] As a preferred embodiment, the universal assembly includes a first pipe joint, a second pipe joint, and a universal connecting rod. Both the first and second pipe joints are provided with positioning shaft grooves for the long screw to pass through, and ball seats are integrally formed in the middle of the inner side of both the first and second pipe joints. Ball heads that mate with the ball seats are fixedly installed at both ends of the universal connecting rod.

[0010] By adopting the above technical solution, the universal assembly can achieve multi-directional deflection adjustment between two adjacent fence frames through the cooperation of ball heads and ball seats at both ends. It can adapt to both horizontal undulations and vertical inclinations of the slope and will not generate additional internal stress at the connection. The first pipe joint and the second pipe joint connect the two fence frames respectively. The structure is simple and the installation and alignment are convenient. The positioning shaft groove and the long screw cooperate to achieve quick installation and locking and high connection reliability.

[0011] As a preferred embodiment, the protective mesh frame includes an equipment mesh frame, an outer metal mesh, and an inner enclosure mesh. The equipment mesh frame has built-in nuts on both sides corresponding to the connecting lugs. The built-in nuts are embedded and fixed in the equipment mesh frame. The outer metal mesh is located at the outer end of the inner enclosure mesh, and both the outer metal mesh and the inner enclosure mesh are fixedly installed in the equipment mesh frame.

[0012] By adopting the above technical solution, the protective net frame adopts a structure of equipment mesh frame and double-layer mesh body. The built-in nut is embedded in the equipment mesh frame, so there will be no problem of slippage and loosening. The connection strength is high. The outer metal mesh can block falling rocks and gravel, improving the safety of protection. The inner fence mesh can block the spread of construction dust, meeting the dust prevention requirements of green construction. It provides double protection and stronger functionality.

[0013] As a preferred embodiment, the angle seat housing includes a top shell, a guide elongated shell, and a movable shaft. A partition plate is fixedly installed in the middle of the top shell. Guide side rods for sliding installation of the movable shaft are provided at both ends of the partition plate, and a support spring for supporting the movable shaft is also sleeved on the outer surface of the guide side rods. A protective outer cover is also provided on the top shell, and the protective outer cover is fixed to the partition plate by bolts. The guide elongated shell is fixedly installed on the lower end face of the top shell. The movable shaft includes an inner support plate and a mating shaft housing. The inner support plate is fixedly installed on the inner end of the mating shaft housing, and the guide side rod passes through the inner support plate and is slidably connected to the mating shaft housing.

[0014] By adopting the above technical solution, the angle seat housing achieves a rotatable connection with the outer ear plate on the back of the enclosure frame through the structure of the top shell and the movable shaft. The support spring provides elastic support for the movable shaft. When disassembling and assembling the angle seat housing, it is only necessary to press the movable shaft to align and insert it into the through hole of the rotating shaft. After releasing, the movable shaft pops out to complete the installation. Disassembly and assembly are very convenient and do not require additional tools. The guide long shell plays a guiding and limiting role for the adjustable extension bracket, ensuring that the adjustable extension bracket will not deviate when sliding and adjusting. The structure of separating the middle plate and the protective outer cover facilitates the maintenance and replacement of internal parts and extends the service life of the device.

[0015] As a preferred embodiment, a back seat is fixedly installed on the rear end face of the frame, and outer ear plates for mounting angle seat housing are integrally formed on both sides of the front end face of the back seat. The outer ear plates are provided with a rotating shaft through hole for rotatably mounting the mating shaft housing, and a guide groove for inserting the mating shaft housing is also provided on the inner side of the outer ear plates. Several sets of side slots for engaging and installing positioning components are evenly provided on both sides of the guide elongated shell.

[0016] By adopting the above technical solution, the back seat and outer ear plate are pre-fixed on the rear side of the frame, eliminating the need for on-site welding and improving assembly efficiency. The through hole of the rotating shaft cooperates with the shaft housing to achieve rotational installation, and the guide groove facilitates the alignment and insertion of the movable shaft, further improving the installation speed. Multiple sets of side slots evenly arranged on the side of the guide shell facilitate the locking of the positioning components, enabling multi-level length adjustment to adapt to different support requirements. The locking reliability is high and it is not easy to loosen.

[0017] As a preferred embodiment, the adjustable extension bracket includes a main slide plate, a reinforcing strip, and a top shell for mounting the positioning components. The lower end of the main slide plate is integrally formed with a horizontal tube seat for rotating the slope fixing seat. The reinforcing strip is integrally formed in the middle of the upper surface of the main slide plate, and the top shell is fixedly installed at the head of the main slide plate.

[0018] By adopting the above technical solution, the adjustable extension bracket uses a main sliding plate combined with a reinforcing strip structure, which has high overall structural strength and is not easy to bend or deform. The top shell provides installation space for the positioning components, and the horizontal tube seat can be easily rotated and connected to the slope fixing seat. The structure is reasonably designed, the force is evenly distributed, and the stability of the support structure is improved.

[0019] As a preferred embodiment, the positioning component includes a main body, a V-shaped spring, and a movable retaining plate corresponding to the side slot. The main body is fixedly installed in the top shell, the V-shaped spring is fixedly installed on the outer side of the main body, the movable retaining plates are symmetrically installed on both sides of the top shell, and the movable retaining plates are slidably connected to the top shell. The inner end of the movable retaining plate is also provided with a bending frame for clamping the V-shaped spring, and the bending frame is fixedly connected to the movable retaining plate.

[0020] By adopting the above technical solution, the positioning component adopts a structure of V-shaped spring sheet and movable clamping plates on both sides. The elasticity of the V-shaped spring sheet can push the movable clamping plate outward and lock it into the side slot. No additional locking parts are needed, making it easy to operate. When locking, it automatically engages due to elasticity and will not loosen due to vibration, ensuring high reliability. The bending frame clamps the V-shaped spring sheet to ensure that the spring sheet is evenly stressed and will not shift or jam.

[0021] As a preferred embodiment, an outer end cover is installed on the upper end face of the top shell, an inner end cover is fixedly installed on the lower end face of the outer end cover, right-angle support plates are fixedly installed on the four corners of the inner end cover, and a concave seat for clamping a V-shaped spring is slidably installed in the middle of the inner end cover, and an auxiliary lever is fixedly installed on the outer end of the concave seat.

[0022] By adopting the above technical solution, the outer end cover and the inner end cover seal the opening of the top shell, preventing dust and dirt from entering the top shell and jamming the positioning components. The concave seat can press the V-shaped spring. When the length needs to be adjusted, simply move the auxiliary lever to drive the concave seat to press the V-shaped spring, allowing the movable plate to retract and unlock. After the adjustment is completed, releasing the auxiliary lever will automatically lock the plate. The operation is very convenient, and one person can complete the adjustment.

[0023] As a preferred embodiment, the slope fixing seat includes a double-headed base, connecting vertical lugs, and a connecting shaft that rotates with the horizontal tube seat. The double-headed base has positioning holes at both ends, the connecting vertical lugs are vertically fixed on both sides of the upper surface of the double-headed base, and the connecting shaft is fixedly connected between the two sets of connecting vertical lugs.

[0024] By adopting the above technical solution, the slope fixing seat is rotatably connected to the connecting shaft and the horizontal tube seat, and the angle of the fixing seat can be adjusted arbitrarily to ensure that the double-headed base and the slope are completely in contact. Positioning holes are opened at both ends of the double-headed base, and the fixing seat can be firmly fixed to the slope by anchor rods or expansion bolts. The connection strength is high, it is not easy to fall off, the structure is simple, the processing is convenient, and the cost is low.

[0025] Compared with existing technologies, the beneficial effects of this invention are as follows: The device adopts a fully prefabricated structure, with all components prefabricated in the factory. On-site installation only requires splicing, eliminating the need for on-site pouring, significantly shortening the construction cycle. After installation, it can be transported to other construction sites for reuse, generating no construction waste and meeting the requirements of green construction. It boasts high turnover rate and reduces construction costs. This device can adapt to slope protection needs with varying gradients and terrain undulations. Adjacent retaining frames utilize a universal hinge structure, adapting to lateral and longitudinal slope changes without internal stress leading to connection breakage. The length and angle of the support structure are adjustable, eliminating the need for large-scale leveling of the original slope, reducing additional earthwork, further lowering construction costs and minimizing damage to the original ecosystem. Meanwhile, this device is easy to install and adjust. A single person can complete the length adjustment and locking operation without complicated tools. It has high assembly efficiency, good protective performance, and dual functions of preventing falling rocks and dust. It meets the safety protection and environmental protection requirements of the construction site. The support structure is stable, the fixing fit is good, and the wind resistance and soil lateral pressure resistance are good. It is not easy to collapse or overturn, and the safety is high.

The bending frame 631 clamps the V-shaped spring 62 to ensure that the spring is evenly stressed and will not shift or jam. An outer end cover 54 is installed on the upper surface of the top shell 53, and an inner end cover 55 is fixedly installed on the lower surface of the outer end cover 54. Right-angle support plates 551 are fixedly installed on the four corners of the inner end cover 55, and a concave seat 552 for clamping a V-shaped spring piece 62 is slidably installed in the middle of the inner end cover 55. An auxiliary lever 553 is fixedly installed on the outer end of the concave seat 552. The outer end cover 54 and the inner end cover 55 seal the opening of the top shell 53 to prevent dust and dirt from entering the interior of the top shell 53 and jamming the positioning component 6. The concave seat 552 can press the V-shaped spring piece 62. When the length needs to be adjusted, simply move the auxiliary lever 553 to drive the concave seat 552 to press the V-shaped spring piece 62, causing the movable clamping plate 63 to retract and unlock. After the adjustment is completed, releasing the auxiliary lever 553 will automatically lock the position. The operation is very convenient, and one person can complete the adjustment work.

[0041] Reference Figure 14The slope fixing seat 7 includes a double-headed base 71, connecting vertical lugs 72, and a connecting shaft 73 that rotatably engages with the horizontal tube seat 511. Positioning holes 711 are provided at both ends of the double-headed base 71. The connecting vertical lugs 72 are vertically fixed to both sides of the upper surface of the double-headed base 71, and the connecting shaft 73 is fixedly connected between the two sets of connecting vertical lugs 72. The slope fixing seat 7 is rotatably connected to the horizontal tube seat 511 via the connecting shaft 73, allowing for arbitrary adjustment of the fixing seat's angle to ensure complete fit between the double-headed base 71 and the slope. Positioning holes 711 are provided at both ends of the double-headed base 71, allowing the fixing seat to be firmly fixed to the slope using anchor rods or expansion bolts. This provides high connection strength, prevents detachment, and features a simple structure, easy processing, and low cost.

[0042] This device is based on a prefabricated splicing design. It adapts to different slopes through adjustable diagonal supports and adapts to undulating terrain through a universal connection structure. The whole unit can be completely disassembled and reused. The specific working process is as follows: Pre-assembly stage: All components are prefabricated in the factory and transported to the construction site. The number of fencing frames 1 to be used is determined based on the slope protection area. The first set of fencing frames 1 is hoisted and placed at the foot of the slope. The bottom ground seat 110 is rotated to ensure it fully conforms to the uneven ground at the foot of the slope, completing the positioning of the first set of fencing frames. Then, the first and second pipe connectors of the universal joint 2 are aligned with the positioning pipe seats 111 of the adjacent two sets of fencing frames. After inserting the long screw 112, the locking nut 113 is tightened to complete the connection of the two sets of fencing frames. During the connection process, the ball joints at both ends of the universal joint can flexibly deflect within the ball seats, allowing adjacent fencing frames to automatically adjust their relative angles according to the lateral undulations of the slope without generating internal stress. After all fencing frames are assembled, the protective net frame 3 is aligned with the connecting ear plates 13 on the fencing frame, and the bolts are tightened to complete the fixing of the protective net frame.

[0043] Support adjustment and fixing stage: After completing the front fence splicing, adjust the length of the back diagonal support: When adjusting, manually push the auxiliary lever 553 downward. The auxiliary lever drives the concave seat 552 to squeeze the V-shaped spring 62. The V-shaped spring is compressed and shrinks, which drives the movable locking plates 63 on both sides to retract inward and exit the side slots 421 on the side of the guide shell, thus unlocking. Then, pull the adjustable extension bracket 5 to slide along the guide shell to adjust the extension length to match the slope of the current slope. After adjustment, release the auxiliary lever. The V-shaped spring resets under the action of elasticity, pushing the movable locking plate to pop out and re-lock into the corresponding side slot, automatically completing the locking. After the length is locked, rotate the lower slope fixing seat 7 so that the double-headed base 71 is completely in contact with the slope. Then, drive the anchor rod through the positioning hole of the double-headed base into the slope to complete the support fixing. During the process, the angle seat shell can automatically rotate and adjust with the support angle to match the support tilt angle.

[0044] Usage phase: After installation, the outer metal mesh can block falling gravel and large debris from the slope, preventing injuries from falling rocks. The inner mesh can prevent construction dust from spreading outward, meeting the dual requirements of safety protection and environmental protection. The overall structure is stable, with good wind and impact resistance, and can adapt to slight deformation of the slope without the problem of connection breakage or collapse.

[0045] Dismantling and Reuse Phase: After construction is completed, first pull out the anchor rods of the slope fixing seat and loosen the locking nuts of the universal assembly. Then all the enclosure units can be disassembled and classified, and transported as a whole to other construction sites for reuse. If individual parts are damaged, they can be disassembled and replaced individually without the need for overall scrapping. This achieves the reusability of the entire device, generates no construction waste, and meets the requirements of green construction.
