Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and more specifically to a flexible protective net structure for the construction of the outer frame of a super high-rise tower. Background Technology
[0002] The construction of the outer frame of a super high-rise tower is a specialized building construction technique. Its process involves numerous structural designs and technical treatments, primarily including key stages such as reinforcement engineering, formwork engineering, and concrete engineering. Mastering and applying this construction technique has a significant impact on improving the overall quality of the construction project.
[0003] In the construction of super high-rise buildings, the construction of the tower's outer frame structure requires primary construction (concrete pouring, which splashes everywhere in the wind, polluting the environment) and secondary construction (outer frame retaining wall, fireproof coating spraying, masonry wall construction, etc.). The protection of the edge areas is of paramount importance. Ordinary mesh protection cannot solve the problems of falling masonry materials, concrete splashing during pouring in strong winds, and paint splashing during fireproof coating spraying when the structural edges are constructed, which will affect the safety of construction. Summary of the Invention
[0004] To overcome the aforementioned deficiencies of the prior art, this invention provides a flexible protective net structure for the construction of the outer frame of a super high-rise tower. Through the fixing holes on the side rails, the plastic-coated steel wire rope A, the movable ring, and the flexible protective net can be installed onto a super high-rise tower without steel beams. Simultaneously, an electromagnet switch can be used to activate a micro-motor and coil, energizing the electromagnet and connecting it to the steel beam, thus enabling the installation of the plastic-coated steel wire rope B and the flexible protective net onto a super high-rise tower with steel beams. These two installation methods allow workers to choose according to actual installation needs, improving operability and practicality, and solving the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a flexible protective net structure for the construction of the outer frame of a super high-rise tower, comprising a flexible protective net for the construction of the protective outer frame of a super high-rise tower;
[0006] The flexible protective netting includes a green screen netting and a wire mesh, with the wire mesh positioned on the outside of the green screen netting.
[0007] The flexible protective net is fixed to the outer frame of the super high-rise tower via a sliding rail connection device.

The structural plate sliding rail connector is used to connect the flexible protective net to the outer frame of the super high-rise tower without steel beams, and the wing plate sliding rail connector is used to connect the flexible protective net to the outer frame of the super high-rise tower with steel beams.
[0008] The flexible protective net is equipped with a wind alarm device to monitor wind speed and remind staff to retract the flexible protective net when the wind force is high.
[0009] In a preferred embodiment, the structural plate slide rail connector includes a plastic-coated steel wire rope A, with a side rail installed on the rear side of the plastic-coated steel wire rope A. Multiple fixing holes are provided on the outer side of the side rail away from the plastic-coated steel wire rope A for installing expansion bolts to connect to the outer frame of the super high-rise tower without steel beams. A movable ring is sleeved on the outer front end of the plastic-coated steel wire rope A, and a connecting plate for connecting a flexible protective net is installed on the outer front end of the movable ring. Two spaced-apart connecting holes are provided inside the connecting plate. Two sets of movable components are installed inside the movable ring. Each set of movable components includes multiple track pulleys installed inside the movable ring, with the end of the track pulley away from the movable ring contacting the plastic-coated steel wire rope A.
[0010] In a preferred embodiment, the wing plate slide rail connector includes a plastic-coated steel wire rope B. The plastic-coated steel wire rope B is provided with a support arm. A support plate for connecting a flexible protective net is installed on the front side of the top of the support arm. The support plate has two spaced support holes. An adjusting arm is rotatably connected to the top of the support arm. Telescopic arms are provided at the ends of the support arm away from the plastic-coated steel wire rope B and the adjusting arm away from the plastic-coated steel wire rope B, respectively. A strong magnet and an electromagnet are respectively installed on the side of the two telescopic arms that are close to each other. Multiple coils and a micro motor connected by wires are installed inside the telescopic arm located on the adjusting arm. An electromagnet switch is installed on the outside of the telescopic arm.
[0011] In a preferred embodiment, both the support arm and the adjusting arm have grooves at their ends away from the plastic-coated steel wire rope B. An adjusting element for adjusting the extension distance of the telescopic arm is provided inside the groove. The adjusting element includes a movable frame located inside the groove, with one end of the movable frame away from the groove fixed to the telescopic arm. Movable holes are provided on both sides of the movable frame. A gear is located inside the movable frame between the two movable holes, and both ends of the gear are fixed to the inner wall of the groove via rotating shafts. The rotating shaft on the gear is located inside the movable hole, and a toothed plate meshes with the outside of the gear. The toothed plate is installed inside the movable frame.
[0012] In a preferred embodiment, a rotating rod is provided on the outer side of the end of the support arm near the groove and on the outer side of the end of the adjusting arm near the groove. The two rotating rods pass through the support arm and the adjusting arm respectively and are fixed together with the rotating shaft on the corresponding gear. Limiting rings are threaded to the outer side of the two rotating rods. A positioning ring is threaded to the outer side of the end of the limiting ring near the rotating rod. The two positioning rings are respectively installed on the side of the support arm and the adjusting arm near the rotating rod.
[0013] In a preferred embodiment, both the cross-section of the movable frame and the cross-section of the groove are rectangular, and the outer side of the movable frame is in contact with the inner wall of the groove.
[0014] In a preferred embodiment, the wind alarm device includes a tension gauge, which is disposed between the connecting plate and the flexible protective net and between the support plate and the flexible protective net.
[0015] The technical effects and advantages of this invention are as follows:
[0016] 1. The plastic-coated steel wire rope A on the side rail can be easily installed onto a super high-rise tower without steel beams by operating the expansion screws through the fixing holes on the side rail. Then, the flexible protective net on the movable ring is slidable to the outside of the plastic-coated steel wire rope A by using the track pulley. At the same time, the micro motor and coil can be turned on by using the electromagnet switch, so that the electromagnet is energized and connected to the steel beam. In this way, the plastic-coated steel wire rope B and the flexible protective net can be installed onto a super high-rise tower with steel beams. This invention provides two installation methods, which can be selected by the staff according to the actual installation needs, improving operability and practicality.
[0017] 2.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0036] Refer to the instruction manual appendix Figure 1-10 The present invention provides a flexible protective net structure for the construction of the outer frame of a super high-rise tower, including a flexible protective net 1 for the construction of the protective outer frame of a super high-rise tower;
[0037] The flexible protective net 1 includes a green screen net 101 and a wire mesh 102, with the wire mesh 102 located on the outside of the green screen net 101;
[0038] Specifically, during the construction of super high-rise towers, the green screen net 101 and wire mesh 102 on the flexible protective net 1 are used together to form a double-layer protection system, which achieves the effects of flame retardancy, fall prevention and blocking of vision, preventing materials from falling and obstructing the workers' vision, giving people a sense of security, and at the same time preventing concrete from splashing and preventing paint from splashing when fireproofing coating is sprayed. This can improve the safety and functional versatility of the invention.
[0039] This invention provides two different connection methods for the flexible protective net 1, such as... Figure 1-10 As shown: The flexible protective net 1 is fixed to the outer frame of the super high-rise tower by a sliding rail connection device. The sliding rail connection device includes a structural plate sliding rail connector 2 and a wing plate sliding rail connector 3. The structural plate sliding rail connector 2 is used to connect the flexible protective net 1 and the outer frame of the super high-rise tower without steel beams, and the wing plate sliding rail connector 3 is used to connect the flexible protective net 1 and the outer frame of the super high-rise tower with steel beams.
[0040] Furthermore, to enhance safety, this invention includes a wind alarm device installed on the flexible protective netting 1 to monitor wind speed and alert workers to retract the flexible protective netting 1 when the wind force is high. Specifically, as shown below... Figure 3 As shown, the wind alarm device includes a tension gauge 4, which is located between the connecting plate 205 and the flexible protective net 1 and between the support plate 303 and the flexible protective net 1. The tension gauge 4 monitors the wind force, thereby ensuring construction safety and preventing accidents.
[0041] Example 1: Connection between flexible protective netting 1 and the outer frame of a super high-rise tower without steel beams.
[0042] like Figure 1-5As shown, the structural plate slide rail connector 2 includes a plastic-coated steel wire rope A201. A side rail 202 is installed on the rear side of the plastic-coated steel wire rope A201. Multiple fixing holes 203 are opened on the outer side of the side rail 202 away from the plastic-coated steel wire rope A201 for installing expansion bolts to connect to the outer frame of the super high-rise tower without steel beams. A movable ring 204 is sleeved on the outer front end of the plastic-coated steel wire rope A201, and a connecting plate 205 for connecting the flexible protective net 1 is installed on the outer front end of the movable ring 204. Two spaced connecting holes 206 are opened inside the connecting plate 205. The movable ring 204 has two sets of movable parts installed inside; each set of movable parts includes multiple track pulleys 207 installed inside the movable ring 204. The end of the track pulley 207 away from the movable ring 204 is in contact with the plastic-coated steel wire rope A201. Through the fixing holes 203 on the side rail 202, the workers can use expansion screws to install the plastic-coated steel wire rope A201 on the side rail 202 to the super high-rise tower without steel beams. Then, the track pulleys 207 are used to slide the movable ring 204 onto the outside of the plastic-coated steel wire rope A201, thereby realizing the installation and fixation of the flexible protective net 1.
[0043] By installing expansion bolts in the fixing holes 203 on the side rail 202 to connect with the super high-rise tower without steel beams, the plastic-coated steel wire rope A201 on the side rail 202 can be installed on the super high-rise tower without steel beams. Then, the tension gauge 4 is installed to connect the movable ring 204 and the flexible protective net 1. Then, the movable ring 204 is slidably fitted onto the outside of the plastic-coated steel wire rope A201 with the help of the track pulley 207. In this way, the flexible protective net 1 can be installed on the outer frame of the super high-rise tower without steel beams.
[0044] Meanwhile, by connecting the tension gauge 4 to the protective net, the tension gauge 4 can monitor the wind force blowing the flexible protective net 1. When the wind force is too strong, the central control unit matched with the tension gauge 4 will issue an alarm and inform the staff that the flexible protective net 1 needs to be disassembled to avoid accidental safety accidents. The staff can directly pull out the movable ring 204 from one end of the plastic-coated steel wire rope A201 to disassemble the flexible protective net 1.
[0045] Example 2: Connection between flexible protective netting 1 and the outer frame of a super high-rise tower with steel beams.
[0046] like Figure 6-8As shown, the wing plate slide rail connector 3 includes a plastic-coated steel wire rope B301. A support arm 302 is provided on the outside of the plastic-coated steel wire rope B301. A support plate 303 for connecting the flexible protective net 1 is installed on the front side of the top of the support arm 302. Two spaced support holes 304 are provided inside the support plate 303. An adjusting arm 305 is rotatably connected to the top of the support arm 302. Telescopic arms 306 are provided at the ends of the support arm 302 and the adjusting arm 305 away from the plastic-coated steel wire rope B301. Strong magnets 307 and electromagnets 308 are installed on the adjacent sides of each telescopic arm 306. Inside the telescopic arm 306 located on the adjusting arm 305, there are multiple coils 309 and a micro motor 310 connected by wires. An electromagnet switch 319 is installed on the outside of the telescopic arm 306. By operating the electromagnet switch 319 to turn on the micro motor 310 and coils 309, the electromagnet 308 can be energized and connected to the steel beam. Thus, the plastic-coated steel wire rope B301 and the flexible protective net 1 can be installed on the super high-rise tower with steel beams.
[0047] Multiple support arms 302 are connected into one unit by plastic-coated steel wire rope B301. Then, a flexible protective net 1 connected to a tension gauge 4 is installed through the support hole 304 on the support plate 303. Subsequently, the telescopic arm 306 on the support arm 302 and the telescopic arm 306 on the adjusting arm 305 are placed on the steel beam of the super high-rise tower. The electromagnet switch 319 is operated to start the micro motor 310 and multiple coils 309, so that the electromagnet 308 can be energized and connected to the steel beam, thereby realizing the installation of the flexible protective net 1 on the super high-rise tower with steel beams.
[0048] At the same time, the wind force is monitored by the tension gauge 4. When the wind force is too strong, the staff will operate the electromagnet switch 319 one by one to turn off the micro motor 310. This will de-energize the electromagnet 308 and separate it from the steel beam. After all the operations are completed, the staff can directly remove the wing plate slide rail connector 3 and the flexible protective net 1 from the plastic-coated steel wire rope B301.
[0049] Additionally, when encountering steel beams of varying widths, the length of the telescopic boom 306 needs to be adjusted, such as... Figure 8-10As shown, the support arm 302 and the adjusting arm 305 of the present invention both have grooves 311 at their ends away from the plastic-coated steel wire rope B301 and the plastic-coated steel wire rope B301, respectively. An adjusting member for adjusting the extension distance of the telescopic arm 306 is provided inside the groove 311. The adjusting member includes a movable frame 312 disposed inside the groove 311. The cross-sections of the movable frame 312 and the groove 311 are both rectangular. The outside of the movable frame 312 contacts the inner wall of the groove 311. By making the cross-sections of the movable frame 312 and the groove 311 both rectangular, the groove 311 can be adjusted accordingly. The movable frame 312 is limited to ensure the stability of the movable frame 312 during displacement. The end of the movable frame 312 away from the groove 311 is fixed to the telescopic arm 306. Movable holes 313 are provided on both sides of the movable frame 312. A gear 314 is provided between the two movable holes 313 and located inside the movable frame 312. Both ends of the gear 314 are fixed to the inner wall of the groove 311 by rotating shafts. The rotating shaft on the gear 314 is located inside the movable hole 313. A toothed plate 315 meshes with the outside of the gear 314 and is installed inside the movable frame 312.
[0050] By engaging gear 314 with toothed plate 315, gear 314 can drive movable frame 312 connected to toothed plate 315 to move outward, and movable frame 312 can then drive telescopic arm 306 to move outward. This makes it easy to adjust the position of electromagnet 308 and strong magnet 307 according to the position of steel beam.
[0051] After the position is adjusted, the limiting and fixing gear 314 needs to be installed, such as... Figure 10 As shown, the support arm 302 near the groove 311 and the adjusting arm 305 near the groove 311 are both provided with rotating rods 316. The two rotating rods 316 pass through the support arm 302 and the adjusting arm 305 respectively and are fixed together with the rotating shaft on the corresponding gear 314. The two rotating rods 316 are threadedly connected to the outside of a limit ring 317. The limit ring 317 near the rotating rod 316 is threadedly connected to a positioning ring 318. The two positioning rings 318 are respectively installed on the side of the support arm 302 and the adjusting arm 305 near the rotating rod 316.
[0052] The connection between the rotating rod 316 and the gear 314 allows the operator to drive the gear 314 to rotate by operating the rotating rod 316. At the same time, the threaded connection between the limiting ring 317 and the rotating rod 316 and the positioning ring 318 allows the rotating rod 316 to rotate freely when the limiting ring 317 is separated from the positioning ring 318. However, when the limiting ring 317 is connected to the positioning ring 318, the rotating rod 316 is restricted and cannot rotate, thereby limiting the rotation of the gear 314.
[0053] like Figure 11As shown, the wire mesh 102 is composed of "double-layer protective wire mesh + unloading spring", that is, the two layers of wire mesh are connected by unloading spring 103. When a falling object occurs, the built-in unloading spring 103 can greatly reduce the impact force and play a protective role by reducing the kinetic energy of the object.
[0054] First, the unloading spring 103 connects to form a buffer zone between the two layers of wire mesh. When external force or impact acts on the wire mesh 102, the unloading spring 103 can absorb and disperse some of the energy, thereby reducing the direct impact of the impact force on the wire mesh 102 body and its rear structure. This design greatly improves the impact resistance of the wire mesh 102, especially when facing strong external impacts or pressures, the unloading spring 103 can effectively buffer the impact through its elasticity, reducing the risk of structural damage.
[0055] Secondly, the combination of the double-layer steel wire mesh and the stress-relieving spring 103 gives the overall structure a certain degree of flexibility and elasticity. This flexibility not only enhances the overall protective capability but also increases the structure's adaptability, allowing it to maintain stability and functionality even in complex environments. For example, when faced with impacts from different directions or with different forces, the extensibility of the stress-relieving spring 103 allows the double-layer steel wire mesh to automatically adjust to adapt to different stress states, thereby better protecting critical components or areas behind it.
[0056] Furthermore, this structural design can also improve the service life of the wire mesh 102. Because the unloading spring 103 can disperse and mitigate impact forces, the stress and fatigue damage borne by the wire mesh 102 body are relatively reduced, thereby extending the service life of the wire mesh 102. The buffering effect of the unloading spring 103 can also reduce the concentrated stress of external forces on the connection points, further improving the stability and durability of the overall structure.
[0057] In summary, this combination of double-layer steel wire mesh and unloading spring 103 not only improves the structure's impact resistance but also enhances its flexibility and service life, enabling the design to provide excellent protection in a variety of harsh environments.
[0058] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
