Abstract
Description
Technical Field
[0001] This utility model relates to the field of building fence technology, and in particular to a foundation pit fence for construction site use. Background Technology
[0002] In construction, it is usually necessary to build a protective net frame around the building to prevent internal facilities from flying out of the construction site during construction, causing personal injury or other economic losses. At the same time, the protective net frame can also prevent non-construction personnel from accidentally entering the construction site and causing safety accidents, thus improving the safety of the construction site.
[0003] A search revealed a construction engineering protective mesh frame with the existing technology announcement number CN222162094U. This frame constructs a combined structure of a first column, a second column, and a flexible protective mesh, enabling modular installation and flexible adjustment of the protective mesh frame. This effectively solves the problems of fixed dimensions and poor spatial adaptability of traditional protective mesh frames. Furthermore, by adding a bottom protective mesh frame and adopting a detachable connection method, it ensures comprehensive coverage and effective protection of the ground operation area, thus compensating for the lack of bottom protection in existing protective mesh frames.
[0004] However, the technical solutions disclosed in the above-mentioned patents still have some defects. Although the coverage of the protective mesh frame can be adjusted by splicing between the protective mesh frame modules, this adjustment method is prone to situations where adding a mesh frame results in an excessive length, while removing a mesh frame results in an insufficient length. It cannot be flexibly adjusted according to the usage environment. At the same time, after the protective mesh frame is damaged, it can only be used by replacement or repair. Whether it is replacement or repair, it requires a long adjustment period. In case of temporary damage, there is often a lack of quick and effective emergency measures. Therefore, this application is filed. Summary of the Invention
[0005] To overcome the technical defects of the existing technology, this utility model provides a foundation pit fence for construction sites, which has the technical characteristics of flexible use and good protective effect.
[0006] The technical solution adopted by this utility model is as follows: it includes a load-bearing base, a first frame, a first protective net frame, a second frame, and a second protective net frame. The first frame is fixed to the top of the load-bearing base, and the first protective net frame is disposed on one side of the first frame. The second frame is movably connected to the load-bearing base through a first guide rod, and the second protective net frame is disposed on one side of the second frame. Leak-proofing components are provided on the side walls of both the first and second protective net frames. The leak-proofing components include a fixed base, a box body, a flexible protective net, and hooks. The fixed base is disposed on the side wall of the first or second protective net frame. The two fixed bases are connected to the box body through a torsion spring shaft. A net-collecting rod is connected to the box body through a torsion spring shaft. One end of the flexible protective net is wound around the net-collecting rod, and the other end extends out of the box body to the outside of the box body. Multiple hooks are provided on the end of the flexible protective net located outside the box body.
[0007] To enhance the stability between the second protective mesh frame and the first frame, this utility model is improved by fixing a second guide rod on the side wall of the first frame, and the second protective mesh frame is slidably connected to the second guide rod.
[0008] To enhance the stability between the first protective mesh frame and the second frame, this utility model is improved by fixing a third guide rod on the side wall of the second frame, and the first protective mesh frame and the third guide rod are slidably connected.
[0009] In order to make the rotation of the threaded post adjustable to adjust the lateral position of the first protective net, the present invention is improved by having a threaded post movably installed inside the second frame, one end of the threaded post being threadedly connected to the bottom frame of the first protective net.
[0010] In order to enable the adjusting handle to control the rotation of the threaded column, the present invention is improved by providing at least two first mating frames on the side wall of the second frame, and an adjusting handle on the outer side wall of the second frame. The axis of the adjusting handle is fixedly connected to the axis of the threaded column, and the adjusting handle is located inside the first mating frame.
[0011] In order to enable the first docking frame to be connected to the adjacent parts of the present invention by means of the docking post, the present invention is improved by providing a docking post at the top of the first docking frame, and a threaded groove on the outer periphery of the top of the docking post, and a nut connected to the threaded groove.
[0012] In order to enable two adjacent parts of this utility model to be connected through the cooperation of the first docking frame and the second docking frame, this utility model is improved by providing a second docking frame on the side wall of the first frame, and the second docking frame is provided with a docking hole into which a docking post can be inserted.
[0013] In order to effectively reduce the overall center of gravity of this utility model, the utility model is improved by the following: the first frame is a hollow structure, and the side wall of the first frame is provided with a water inlet for injecting water into the inner cavity.
[0014] In order to ensure that the first and second frames can be tightly adhered to each other in the storage state and maintain high stability, the present invention is improved by providing magnetic strips on the side walls of the box body for adsorbing the first or second frame in the storage state.
[0015] The beneficial effects of this utility model are: This utility model adopts a telescopic structure with a repair component. The telescopic structure can adjust the coverage length of the fence according to the actual scenario, and it will not be too long or too short in actual application. The telescopic structure further enhances the flexibility of the repair component. Both the first and second protective net frames have repair components at their ends, and the two are staggered. No matter whether the first or second protective net frame is partially damaged, it can be temporarily repaired with the repair component on the other protective net frame. The operation is simple and convenient, highly flexible, and effectively solves the problem of existing fences being unable to be repaired in time when suddenly damaged. Attached Figure Description

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-6 As shown, this embodiment provides a foundation pit fence for construction site, including a load-bearing base 1, a first frame 2, a first protective net frame 3, a second frame 4, and a second protective net frame 5. The first frame 2 is fixed to the top of the load-bearing base 1, the first protective net frame 3 is disposed on one side of the first frame 2, the second frame 4 is movably connected to the load-bearing base 1 through a first guide rod 7, and the second protective net frame 5 is disposed on one side of the second frame 4. Leak repair parts 6 are provided on the side walls of both the first protective net frame 3 and the second protective net frame 5.
[0019] Based on the above description Figure 1 The bottom end of the load-bearing base 1 and the bottom end of the second frame 4 are at the same horizontal level, ensuring that the second frame 4 can cooperate with the load-bearing base 1 to maintain the stability of the overall structure even when it moves. The first protective net frame 3 and the second protective net frame 5 are fixed on the first frame 2 and the second frame 4 respectively. When they are folded up, they overlap. When the second frame 4 moves outward, the first protective net frame 3 and the second protective net frame 5 separate and the coverage length increases accordingly. In practical applications, the coverage length of this fence can be flexibly adjusted by simply pulling the second frame 4. In addition, the ends of the first guide rod 7, the second guide rod 8 and the third guide rod 9 in this fence all have limiting structures. For example, the end of the first guide rod 7 inserted into the load-bearing base 1 is designed with an anti-detachment rope or anti-detachment block to prevent the first guide rod 7 from completely separating from the load-bearing base 1 and causing the structure to fall apart. The second guide rod 8 and the third guide rod 9 adopt the same design, which will not be described in detail below.
[0020] The leak repair component 6 includes a fixing base 601, a housing 602, a flexible protective net 603, and hooks 604. The fixing base 601 is disposed on the side wall of the first protective net frame 3 or the second protective net frame 5. The two fixing bases 601 are connected to the housing 602 by a torsion spring shaft. A net-retrieving rod is connected inside the housing 602 by a torsion spring shaft. One end of the flexible protective net 603 is wound around the net-retrieving rod, and the other end extends out of the housing 602 to the outside of the housing 602. Multiple hooks 604 are provided on the end of the flexible protective net 603 located outside the housing 602. In actual use, when either the first protective net frame 3 or the second protective net frame 5 is damaged, the first protective net frame is adjusted first. The relative positions of the second protective net frame 5 and the repair part 6 box 602 are such that the box 602 of the repair part 6 is on the side of the damaged area. Then, the flexible protective net 603 is pulled out from the box 602 and the hook 604 is used to hang the flexible protective net 603 on the other side of the damaged area of the protective net frame that needs to be repaired, opposite to the box 602. This allows the flexible protective net 603 to cover the damaged area and provide temporary protection. Furthermore, since the flexible protective net 603 is connected to the net-collecting rod through a torsion spring shaft, when the flexible protective net 603 is not needed, the hook 604 is released, and the flexible protective net 603 will automatically roll around the net-collecting rod under the elastic force of the torsion spring shaft and be stored in the box 602, which is both convenient and space-saving.
[0021] A second guide rod 8 is fixed on the side wall of the first frame 2, and the second protective mesh frame 5 is slidably connected to the second guide rod 8. A third guide rod 9 is fixed on the side wall of the second frame 4, and the first protective mesh frame 3 is slidably connected to the third guide rod 9. The setting of the second guide rod 8 and the third guide rod 9 effectively ensures the stability of the overall structure. In practical applications, sufficient grease needs to be applied to the first guide rod 7, the second guide rod 8 and the third guide rod 9 to ensure the stable operation of the sliding structure.
[0022] A threaded post 10 is movably installed inside the second frame 4. One end of the threaded post 10 is threadedly connected to the bottom frame of the first protective net. At least two first mating frames 12 are provided on the side wall of the second frame 4. An adjusting handle 11 is provided on the outer side wall of the second frame 4. The axis of the adjusting handle 11 is fixedly connected to the axis of the threaded post 10, and the adjusting handle 11 is located inside the first mating frame 12. In actual operation, by rotating the adjusting handle 11, the threaded post 10 can be rotated. Since the threaded post 10 is threadedly connected to the bottom frame of the first protective net, the rotation of the threaded post 10 will cause... The distance between the first protective net and the second frame 4 changes, thereby adjusting the position of the second frame 4, and thus adjusting the relative position of the first protective net frame 3 and the second protective net frame 5. In practical applications, the coverage length of the first protective net frame 3 and the second protective net frame 5 can be flexibly adjusted according to the construction needs of the foundation pit. At the same time, the setting of the first docking frame 12 can also provide a stable installation position for the adjustment handle 11. In addition, to ensure the stability of outdoor use, the threaded column 10 and the load-bearing seat 1 are both made of rust-proof material or coated with rust-proof coating to avoid surface rust affecting use.
[0023] The top of the first connecting frame 12 is provided with a connecting post 13, and the outer periphery of the top of the connecting post 13 is provided with a threaded groove 17. A nut is connected to the threaded groove 17. The side wall of the first frame 2 is provided with a second connecting frame 14. The second connecting frame 14 is provided with a connecting hole 15 for inserting the connecting post 13. When it is necessary to assemble the two fences, the connecting post 13 at the top of the first connecting frame 12 on the second frame 4 of fence A is inserted into the connecting hole 15 of the second connecting frame 14 on the side wall of the first frame 2 of fence B. At this time, the threaded groove 17 at the top of the connecting post 13 is exposed outside the second connecting frame 14. Then, the nut is screwed into the threaded groove 17 and tightened. Through the cooperation of the nut and the threaded groove 17, the second frame 4 of fence A and the first frame 2 of fence B are connected together, which ensures the safety and reliability of the foundation pit fence during the construction process on the construction site and effectively prevents safety accidents such as fence collapse caused by loose connection.
[0024] The first frame 2 is a hollow structure. The side wall of the first frame 2 is provided with a water inlet for injecting water into the inner cavity. An appropriate amount of water can be injected into the inner cavity of the first frame 2 through the water inlet. On the one hand, the injected water can increase the overall weight of the fence and lower the overall center of gravity, making it more stable in the complex environment of the construction site and less likely to be blown down by the wind or moved by external force, thus further improving the safety of the fence during construction. On the other hand, in cold environments such as winter, warm water can be injected as needed to prevent the first frame 2 from becoming fragile and vulnerable due to low temperature, thus extending the service life of the fence. The water inlet is provided with a sealing cap, which can be tightened after water injection to prevent water from leaking out of the inner cavity.
[0025] Magnetic strips 605 are provided on the side wall of the box body 602 for adsorbing the first frame 2 or the second frame 4 when stored. When storing the enclosure, firstly, the first frame 2 and the second frame 4 are controlled to merge. Then, the magnetic strips 605 are used to attract the first frame 2 and the second frame 4 to the magnetic strips 605 on the two leak-proof parts 6 respectively, improving the safety and convenience of storage. In addition, since the two fixing seats 601 of the leak-proof part 6 are connected to the box body 602 by a torsion spring shaft, this structural design allows the box body 602 to automatically deflect when leak repair is needed due to the tension of the flexible protective net 603, and automatically return to its original position when leak repair is not needed. Figure 1 This state ensures that the magnetic strip 605 can be attracted to either the first frame 2 or the second frame 4.
