Description

Technical Field

[0001] This utility model relates to the field of wire mesh fence technology, and more specifically, to a modified structure for single-layer wire mesh fencing for airports that can operate without interruption. Background Technology

[0002] During the construction of civil aviation expansion and renovation projects, in accordance with the management regulations for construction without interrupting operations at transport airports, there must be clear isolation measures between the construction area and the operating area. To reduce the difficulty of airport management and construction, temporary fencing is often used to isolate some construction areas within the airport, turning construction in the controlled area into construction in the uncontrolled area.

[0003] The existing airport's current method of enclosure without stopping operations has many problems:

[0004] 1. Using iron or stone barriers for enclosure is inherently unstable and the enclosure height is insufficient, posing a risk of intrusion and crossing.

[0005] 2. When using perimeter fencing, concrete fixing is often employed. Although this method offers high stability and meets height requirements, it results in low construction efficiency. Furthermore, because concrete is used for fixing, the material cannot be reused, leading to high costs and significant resource waste.

[0006] 3. The existing fence structure has a fixed length and a fixed enclosure range. When it is impossible to install an integer number of fence structures within the preset range, the isolation may not be tight, leaving gaps or gaps. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a modification structure for single-layer fencing mesh that allows airports to operate without interruption.

[0008] The technical solution adopted in this utility model is:

[0009] A single-layer fencing structure for airport non-stop operation includes: a fencing frame, with a fencing net body installed inside the fencing frame; two opposing column mechanisms are slidably connected to both ends of the fencing frame, and each column mechanism has an inverted T-shaped support at its bottom, with a counterweight mechanism detachably connected to both ends of the two inverted T-shaped supports.

[0010] Furthermore, the column mechanism includes: a column body, with two upper and lower crossbeams welded to the side of the column body near the perimeter fence frame. The two crossbeams are slidably installed in two horizontal sliding grooves in the top and bottom frames of the perimeter fence frame. Side sliders are fixedly connected to both crossbeams. The two side sliders are slidably installed in two side sliding tracks in the top and bottom frames of the perimeter fence frame. The two side sliding tracks are connected to the two horizontal sliding grooves one by one.

[0011] Furthermore, a tightening bolt is screwed onto the side slider, and the tightening bolt can pass through the through hole of the crossbeam and abut against the inner wall of the horizontal sliding groove.

[0012] Furthermore, multiple sliding guide shafts evenly distributed from top to bottom are fixedly connected to the side of the column body, and the middle of the multiple sliding guide shafts are slidably installed in multiple transverse through holes of the side frame of the perimeter fence.

[0013] Furthermore, one end of multiple sliding retaining shafts inserted into the inner side of the perimeter fence is fixedly connected to the anti-detachment longitudinal beam.

[0014] Furthermore, the upper and lower surfaces of the anti-detachment longitudinal beam slide in contact with the top and bottom surfaces of the perimeter grid installation groove.

[0015] Furthermore, the longitudinal support leg in the middle of the inverted T-shaped support is slidably installed in the rectangular groove at the bottom of the column body, and the column body and the longitudinal support leg are connected by bolts and nuts.

[0016] Furthermore, two triangular reinforcing plates are fixed to the upper surface of the horizontal support leg of the inverted T-shaped support, and the inner surfaces of the two triangular reinforcing plates are slidably fitted onto the two sides of the column body.

[0017] Furthermore, rectangular grooves are provided at both the front and rear ends of the inverted T-shaped support's horizontal leg; the counterweight mechanism includes: a counterweight box, with rectangular pins on the counterweight box inserted into the rectangular grooves, and assembly screws screwed onto the horizontal leg inserted into the longitudinal slots of the rectangular pins; the top of the counterweight box has an inlet, and a box cover is fastened above the inlet; a drain pipe fixed on the side of the counterweight box communicates with the internal cavity of the counterweight box; a plug is sealed inside the drain pipe, and the plug head is located inside the counterweight box.

[0018] Furthermore, a dense mesh net is installed on the perimeter of the perimeter fence.

[0019] As can be seen from the above solution, the beneficial effects of this utility model are as follows:

[0020] This utility model discloses a modified structure for a single-layer perimeter fencing that allows for uninterrupted airport operations. The relative positions of the internal perimeter fencing frame and the two column mechanisms are adjustable, thereby forming fencing structures with different enclosure lengths. This facilitates adjustment according to actual conditions and reduces problems such as inadequate isolation, gaps, or gaps. The two column mechanisms, the inverted T-shaped supports, and the counterweight mechanism all adopt detachable connection structures, which are not only easy to disassemble and reuse but also easy to transport and move.

[0031] To ensure a clear and complete description of the technical solutions in the embodiments of this utility model below, in conjunction with the accompanying drawings, it is evident that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0033] Please see Figures 1-7The present invention provides a single-layer fencing modification structure for airports that do not require flight operations, comprising: a fencing frame 1, a fencing body 2 installed inside the fencing frame 1; two opposing column mechanisms 3 slidably connected to both ends of the fencing frame 1, each column mechanism 3 having an inverted T-shaped support 4 at its bottom, and both ends of the two inverted T-shaped supports 4 being detachably connected to a counterweight mechanism 5.

[0034] The working principle and technical effects of the above technical solution are as follows:

[0035] In this utility model, a single-layer fencing structure for airport non-stop operation is provided. A fencing body 2 is installed inside the fencing frame 1, and a dense mesh net is installed on the fencing body 2 to effectively shield the area. Two opposing column mechanisms 3 are slidably connected at both ends of the fencing frame 1. The relative positions of the two column mechanisms 3 and the fencing frame 1 are adjustable. When an integer number of fencing structures cannot be installed within a preset range, fencing structures with different enclosure lengths can be formed according to the actual situation. Adjustments can be made according to the actual situation to reduce problems such as incomplete isolation, gaps, or gaps. The two column mechanisms, the inverted T-shaped support, and the counterweight mechanism all adopt detachable connection structures, which are not only easy to disassemble and reuse, but also easy to transport and move.

[0036] The above solution has the following advantages:

[0037] 1. The length of the enclosure can be flexibly adjusted. The relative positions of the column mechanisms 3 at both ends of the enclosure frame 1 and the enclosure frame 1 are adjustable. When an integer number of enclosure structures cannot be installed within the preset range, enclosure structures of different lengths can be formed according to the actual situation. This effectively reduces the problems of inadequate isolation, gaps, or gaps. It can more completely and continuously separate the construction area from the operation area, reduce the risk of personnel and vehicles accidentally entering, and ensure the safety of airport construction and operation.

[0038] 2. The perimeter fence body 2 is equipped with a dense mesh net, which can effectively shield the construction area and further enhance the separation between the construction area and the operation area. This prevents unauthorized personnel from spying on the construction process or prevents items, dust and other debris from being blown out of the construction area and affecting the operation area. It also helps to improve the overall safety and order of the airport.

[0039] 3. Easy to assemble, disassemble, and reuse: The two column mechanisms, inverted T-shaped supports, and counterweight mechanism all adopt detachable connection structures, making the installation and dismantling of the fence mesh modification structure more convenient and quick. During construction, the installation and removal of the fence can be flexibly adjusted according to the project schedule, improving construction efficiency. Furthermore, this detachable structure facilitates the reuse of materials, reducing resource waste.

[0040] 4. Reduced material costs: The components are detachable and reusable, reducing the high costs associated with disposable materials. Compared to traditional concrete-fixed fencing panels that cannot be reused, this solution offers a significant advantage in material costs, improving resource utilization and reducing overall construction costs. Furthermore, by flexibly adjusting the fencing length, it avoids the additional costs associated with temporary measures (such as adding warning signs or assigning personnel) needed to compensate for incomplete fencing, further optimizing cost-effectiveness.

[0041] The column mechanism 3 includes: a column body 31, with two horizontal beams 32 welded to the side of the column body 31 near the perimeter fence frame 1. The two horizontal beams 32 slide in two horizontal sliding grooves in the top and bottom frames of the perimeter fence frame 1. Side sliders 33 are fixedly connected to both horizontal beams 32, and the two side sliders 33 slide in two side sliding tracks in the top and bottom frames of the perimeter fence frame 1. The two side sliding tracks are connected to the two horizontal sliding grooves one by one. Tightening bolts 34 are screwed onto the side sliders 33, and the tightening bolts 34 can pass through the through holes of the horizontal beams 32 and abut against the inner wall of the horizontal sliding groove. Multiple sliding axles 35 are fixedly connected to the side of the column body 31, evenly arranged from top to bottom. The middle of the multiple sliding axles 35 slides in multiple horizontal through holes in the side frame of the perimeter fence frame 1.

[0042] The structural design of the column mechanism 3 makes its adjustment very convenient. When it is necessary to adjust the relative position of the column mechanism 3 and the fence frame 1, pulling the column body 31 controls the upper and lower crossbeams 32 to slide in the two horizontal sliding grooves of the top and bottom frames of the fence frame 1. The column body 31 can also drive multiple sliding stop shafts 35 to slide in multiple horizontal through holes of the side frame of the fence frame 1. The multiple sliding stop shafts 35 act as a barrier to prevent people from entering through the gap between the column body 31 and the fence frame 1. The tightening bolts 34 are screwed onto the side sliders 33. After adjusting the relative position of the two crossbeams 32 and the two horizontal sliding grooves, the tightening bolts 34 can be controlled to pass through the through holes of the crossbeams 32 and press against the inner wall of the horizontal sliding groove, thereby fixing the relative position of the column mechanism 3 and the fence frame 1, preventing them from loosening and improving the stability during use.

[0043] Multiple sliding retaining shafts 35 are inserted into the inner side of the fence frame 1 and fixedly connected to the anti-detachment longitudinal beam 36. The upper and lower surfaces of the anti-detachment longitudinal beam 36 slide in contact with the top and bottom surfaces of the mounting groove of the fence frame 1. The anti-detachment longitudinal beam 36 prevents the multiple sliding retaining shafts 35 from detaching from the fence frame 1 and enhances the overall strength of this utility model.

[0044] The longitudinal support leg 41 in the middle of the inverted T-shaped support 4 is slidably installed in the rectangular groove at the bottom of the column body 31. The column body 31 and the longitudinal support leg 41 are connected by bolts and nuts, making it very convenient to connect and disassemble the inverted T-shaped support 4 and the column body 31.

[0045] The upper surface of the horizontal support leg 42 of the inverted T-shaped support 4 has two triangular reinforcing plates 43 fixed relative to each other, and the inner surfaces of the two triangular reinforcing plates 43 are slidably fitted on the two sides of the column body 31.

[0046] The two triangular reinforcing plates 43 play a multifaceted and important role in the modification structure of the single-layer perimeter fencing at this airport without interrupting operations, as detailed below:

[0047] 1. Enhance structural stability, distribute stress, and prevent lateral tilting. When the enclosure is subjected to external forces (such as wind, collisions, etc.), the column body 31 needs to bear a certain load. The triangular reinforcing plate 43 slides with the two sides of the column body 31, which can distribute the force on the column body 31 to the horizontal support leg 42 of the inverted T-shaped support 4. The triangle itself has stability. This structural design can make the support system composed of the entire inverted T-shaped support 4 and the column mechanism 3 more stable, prevent structural deformation or damage due to excessive local stress, and improve the overall wind and impact resistance of the enclosure. The triangular reinforcing plate 43 plays a restraining role on both sides of the column body 31, limiting the swaying and tilting of the column body 31 in the horizontal direction, ensuring the stability of the enclosure, and ensuring effective isolation between the construction area and the operation area.

[0048] 2. Assisted connection and positioning: The inner sides of the two triangular reinforcing plates 43 slide relative to each other on the two sides of the column body 31. During the installation process, they can play a guiding role, helping the column body 31 to accurately connect with the inverted T-shaped support 4, ensuring that the longitudinal support leg can smoothly slide into the rectangular groove at the bottom of the column body, thus improving the accuracy and efficiency of the installation.

[0049] The inverted T-shaped support 4 has rectangular grooves 44 at both the front and rear ends of the horizontal support leg 42; the counterweight mechanism 5 includes: a counterweight box 51, a rectangular insert 52 on the counterweight box 51 inserted into the rectangular groove 44, an assembly screw screwed on the horizontal support leg 42 inserted into the longitudinal slot of the rectangular insert 52, an inlet at the top of the counterweight box 51, a box cover 53 fastened above the inlet, a drain pipe 54 fixed on the side of the counterweight box 51 communicating with the internal cavity of the counterweight box 51; a plug 55 is sealed inside the drain pipe 54, and the plug of the plug 55 is located inside the counterweight box 51.

[0050] The counterweight mechanism 5 employs a method where the counterweight box 51 is inserted into the rectangular slot 44 of the horizontal support leg 42 of the inverted T-shaped support 4 via a rectangular insert 52, achieving rapid positioning and initial connection. This modular design allows the counterweight mechanism 5 to quickly find its accurate position during installation, reducing installation difficulty and improving efficiency. The counterweight mechanism 5 is reliably connected to the inverted T-shaped support 4 by using assembly screws screwed onto the horizontal support leg 42 and inserted into the longitudinal slot of the rectangular insert 52. This connection method also facilitates disassembly; simply unscrewing the assembly screws allows the counterweight mechanism 5 to be easily separated from the inverted T-shaped support 4, facilitating the overall disassembly and transportation of the enclosure structure and aiding in subsequent maintenance and replacement operations.

[0051] The counterweight box 51 has an inlet at the top that is connected to the cover 53, allowing counterweight materials (such as sand, water, etc.) to be added or removed by opening the cover. This allows for flexible adjustment of the counterweight weight according to actual needs in different usage scenarios to meet the stability requirements of the perimeter structure. For example, in windy environments, the counterweight weight can be increased appropriately; while when the perimeter structure needs to be moved, the counterweight weight can be reduced to simplify handling.

[0052] The counterweight box 51 is equipped with a drain pipe 54 on the side and is sealed with a plug 55. When it is necessary to quickly reduce the weight of the counterweight (such as when it is necessary to move the perimeter structure urgently) or empty the counterweight box 51, simply open the plug 55 and the liquid in the counterweight box (if water is added as counterweight) can be discharged through the drain pipe. The operation is simple and convenient, which improves the efficiency of counterweight adjustment.

[0053] By setting counterweight mechanisms 5 at both ends of the inverted T-shaped support 4, the weight at the bottom of the enclosure structure is increased, the center of gravity is lowered, and the overall stability of the enclosure structure is improved. When subjected to external forces (such as wind, collisions, etc.), it can better resist tipping and shaking, ensure effective isolation between the construction area and the operating area, and ensure the safety of airport operations.

[0054] The plug 55 is located inside the counterweight box 51. When the counterweight medium inside the counterweight box 51 is liquid, the plug 55, under the action of liquid pressure, can better press against the opening of the drain pipe 54, forming a tighter seal. Compared with the case where the plug is on the outside, this design can effectively prevent counterweight liquid leakage, ensure the sealing of the counterweight box, and maintain the stability and effectiveness of the counterweight.
