Description

Technical Field

[0001] This utility model relates to the field of building construction scaffolding, and in particular to a telescopic protective net structure for climbing formwork and scaffolding. Background Technology

[0002] In the construction of high-rise buildings, climbing formwork and scaffolding are crucial construction equipment, and the adaptability of their external protective systems directly affects construction efficiency and safety. Traditional external protective systems have significant limitations: as the building facade gradually shrinks with increasing height, the protective netting requires frequent manual cutting and modification. This not only increases construction steps and material waste but may also lead to gaps or insufficient strength in the protective system. Furthermore, conventional protective netting uses a fixed connection method, which cannot adapt to dynamic changes in the building's cross-section. Construction workers often need to adjust the size of the protective netting layer by layer, which is both time-consuming and poses safety hazards.

[0003] Furthermore, existing protective netting connection structures are mostly rigidly fixed, lacking effective expansion and contraction adjustment mechanisms. This makes them prone to deformation or interference when the support columns lean towards the building structure. These technical defects not only affect construction progress but may also lead to a decrease in the overall stability of the protective netting system, increasing the risk of falling objects from heights.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0037] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] In existing technologies, the external protective structures of climbing formwork used in building construction typically employ a fixed protective net design. As the building facade gradually tapers inward with increasing height, the protective net cannot adapt to these structural changes, requiring manual layer-by-layer cutting or modification. This not only increases construction steps and material waste but can also lead to gaps at the net's joints, affecting overall safety and aesthetics. Especially in high-rise buildings or irregularly shaped structures, frequent adjustments to the protective net significantly reduce construction efficiency and increase labor costs.

[0039] To address the aforementioned issues, a protective netting system capable of automatically adapting to changes in structural dimensions needs to be designed. Considering the need for the protective netting to expand and contract synchronously with the scaffolding as it climbs, it must be decomposed into multiple independent layers, with an adjustable connection structure established. By analyzing the force transmission path between the scaffolding columns and the protective netting, laterally arranged telescopic square tubes were chosen as the primary adjustment components, coupled with detachable connectors to achieve longitudinal displacement of the protective netting panels. Simultaneously, to prevent interference between different layers of the protective netting during expansion and contraction, the connection relationships between each layer must be restricted, allowing for independent movement.

[0040] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, based on the above design concept, this application proposes a frame column 100 arranged on the left and right sides according to the expansion and contraction of the building structure cross-section, and several layers of protective netting assemblies detachably installed on each frame column 100. Each layer of protective netting assembly consists of several mesh connecting supports 200, telescopic square tubes 300, locking bolts 400, and protective mesh panels 500. The inner end of the mesh connecting support 200 is detachably installed on the frame column 100, and a telescopic square tube 300 is horizontally arranged on its top. The telescopic square tube 300 is connected to the top end of several protective mesh panels 500 arranged along its length below by several locking bolts 400; and the lower end of each protective mesh panel 500 is not connected to another layer of protective netting assembly below.

[0041] Among them, the frame column 100 refers to the supporting component that is vertically installed on the outside of the building structure. It can be made of square steel pipe or I-beam and fixed to the building structure through embedded parts or connecting plates. The spacing between the left and right frame columns 100 can be adjusted according to the dimensions of the building facade. During installation, they are arranged at an angle in the height direction along with the building structure cross-section, tapering inwards. Figure 4 , Figure 5 and Figure 6 As shown. The mesh connecting support 200 is a transition component used to connect the frame column 100 and the protective mesh 500. It can be made of H-beam steel. The upper and lower grooves are used to accommodate the telescopic square tube 300 and the protective mesh 500, respectively. The mounting holes opened on it can realize multi-directional connection.

[0042] The telescopic square tube 300 refers to a lateral support component with adjustable length, featuring equidistant mounting holes for fixed position adjustment via bolt connections. The locking bolt 400 is a fastener used to secure the telescopic square tube 300 to the protective mesh panel 500; specifically, hexagonal head bolts with anti-loosening washers can be used. The protective mesh panel 500 is a protective unit composed of a metal frame and a perforated mesh plate. Specifically, it can be a welded square tube frame with internally welded diamond-shaped mesh plates, and mounting holes on the frame for connecting adjacent mesh panels.

[0043] Specifically, the support system is formed by the inclined arrangement of the frame columns 100 along the cross-section of the building facade. Each layer of protective netting assembly is installed at a corresponding height position via mesh connecting supports 200. The mesh connecting supports 200 are fixedly connected to the frame columns 100 with bolts. A telescopic square tube 300 is placed in the groove at the top, and the top of the protective netting 500 is supported by the groove at the bottom. The telescopic square tube 300 extends laterally and is connected to the protective netting 500 below it via locking bolts 400. The building facade tapers inward in the height direction to form a trapezoidal cross-section. Frame columns 100 are installed on both sides, and corresponding protective netting 500 is erected on the outside of this trapezoidal cross-section using the frame columns 100, forming building protection. The number of protective netting 500 in each layer of protective netting assembly is laid according to the spacing between the left and right frame columns 100, realizing the expansion and contraction of the protective netting 500 in the height direction.

[0044] Through the above technical solution, this application achieves the function of the protective netting moving inwards along with the building structure's exterior protective netting panel 500, eliminating the need for manual cutting and modification. The modular design of the protective netting components allows for quick assembly and disassembly, reducing construction difficulty and material waste. The layered, independent structure avoids interference between different levels of the protective netting, ensuring continuous protection. The telescopic square tube 300, in conjunction with the standardized netting connecting support 200, adapts to the needs of building structures of different sizes.

[0045] In some of these embodiments, such as Figure 1 and Figure 3 As shown, this application further proposes that each layer of protective netting components is arranged horizontally, and both ends or the middle are detachably installed on the frame column 100 through netting connection supports 200, and the two adjacent netting connection supports 200 are connected by the same telescopic square tube 300.

[0046] The horizontal arrangement refers to the arrangement and extension of the protective netting components along the horizontal extension direction of the frame columns 100, covering the horizontal area of ​​the building facade. Specifically, this can be achieved by splicing multiple protective netting panels horizontally to form a continuous protective surface, adapting to the changes in the horizontal dimensions of different building structures. The connection between adjacent netting panels and support 200 via a single telescopic square tube 300 refers to the connection structure between two adjacent supports via a single square tube 300, used to support multiple protective netting panels 500 mounted on them.

[0047] Specifically, when the protective netting components are arranged horizontally, their two ends or middle positions are installed on the frame columns 100 via multiple mesh connecting supports 200, forming multiple support points to distribute the load and improve stability. This application's protective netting component arrangement scheme solves the problem of poor installation stability of horizontal protective netting, realizes the expansion and contraction function of the protective netting as the building structure changes, reduces manual adjustment procedures, and improves the overall stability of the protective system through a rigid linkage structure.

[0048] In some of these embodiments, such as Figure 1 and Figure 2 As shown, this application further proposes that the cross-section of the mesh connecting support 200 is H-shaped, with the end of the telescopic square tube 300 installed in the groove at the top and the top of the protective mesh 500 installed in the groove at the bottom.

[0049] The H-shaped structure refers to the cross-sectional shape formed by two parallel vertical plates and a middle horizontal connecting plate. It can be formed by stamping steel plates or cutting profiles. The top and bottom grooves are used to accommodate the telescopic square tube 300 and the protective mesh 500, respectively. The depth of the top and bottom grooves can be 1.2-1.5 times the height of the telescopic square tube, forming a wrapping constraint on the ends of the telescopic square tube 300 and the protective mesh 500. The width of the top and bottom grooves is 2-4 times the thickness of the telescopic square tube 300. Several mounting holes are provided at the bottom of the grooves, allowing adjustment of the installation position of the locking bolts 400 to meet the installation requirements of the telescopic square tube 300 and the protective mesh 500 retracting inwards.

[0050] Specifically, such as Figure 2 As shown, this application further proposes that the inner wall of the mesh connecting support 200 has first mounting holes 201 at the upper and lower ends, several second mounting holes 202 arranged at intervals in the middle, and third mounting holes 203 at the upper and lower ends of the outer wall. The inner end of the mesh connecting support 200 is connected to the frame column 100202 by mounting bolts through the first mounting holes 201, the middle part is fixed with locking bolts through the second mounting holes to fix the telescopic square tube 300 and the protective mesh 500, and the outer end is fixed with the mesh reinforcing rib 700 through the third mounting holes 203.

[0051] When the protective netting assembly needs to be installed on the support column 100, the netting connecting support 200 is first fixed to the predetermined height position of the column through the first mounting hole 201. Then, the telescopic square tube 300 is embedded into the groove at the top of the support, and the locking bolt 400 is passed through the second mounting hole 202, forming an adjustable-spacing rigid connection between the telescopic square tube 300 and the top of the protective netting 500 below. Finally, the netting reinforcing rib 700 is installed at the third mounting hole 203 on the outside of the support, forming a lateral support system. When the building structure cross-section shrinks, the telescopic square tube 300 can slide along the groove at the top of the support, causing the protective netting 500 to rotate around the bolt in the second mounting hole 202 as the rotation center, while the netting reinforcing rib 700 maintains lateral constraint through the third mounting hole 203 and the bolt.

[0052] In some of these embodiments, such as Figure 2 As shown, this application further proposes that a number of fourth mounting holes 301 are opened at equal intervals along the length direction of the telescopic square tube 300, which are detachably connected to the top of a number of protective mesh panels 500 below by a number of locking bolts 400 respectively.

[0053] The fourth mounting hole 301 refers to the through holes opened at fixed intervals on the surface of the telescopic square tube 300, with the hole spacing ranging from 200mm to 500mm. These equidistantly arranged holes provide an adjustable installation reference for the protective mesh 500. The locking bolt 400 is a fastener with an anti-loosening nut, which achieves a rigid connection between the protective mesh 500 and the telescopic square tube 300 through threaded engagement. When tightened, this bolt can withstand the weight of the protective mesh 500 and wind loads.

[0054] In addition, such as Figure 3 As shown, this application further proposes that one end of the telescopic square tube 300 is detachably connected to the mesh connecting support 200 via a locking bolt 400 through the corresponding fourth mounting hole 301, while the other end is directly overlapped on the top of the corresponding mesh connecting support 200. Direct overlap means that the end of the telescopic square tube 300 forms a planar contact with the top of the mesh connecting support 200, without using bolts to form a fixed mechanical connection structure. This allows the other end of the telescopic square tube 300 to maintain sliding freedom within the groove on the top of the mesh connecting support 200 without bolt constraints.

[0055] In some of these embodiments, such as Figure 1 and Figure 3As shown, this application further proposes that the protective mesh 500 consists of a square frame and a perforated plate fixedly welded to the square frame. The square frame is composed of two sets of parallel horizontal square tubes 501 and vertical square tubes 503 welded together, with diagonal sections connected by oblique square tubes 505 welded together. The square frame refers to a square frame structure formed by welding two sets of horizontal square tubes 501 and vertical square tubes 502. The oblique square tubes 505 refer to reinforcing tubes arranged along the diagonal direction of the square frame; specifically, they can be square tubes of the same material as the horizontal square tubes 501, forming a triangular stable structure to resist torsional deformation. The perforated plate refers to a conventionally known metal sheet with a uniformly perforated structure; specifically, it can be a perforated steel plate with a 10mm aperture, welded and fixed to the square frame to form a covering layer that combines protection and breathability.

[0056] Specifically, the horizontal square tubes 501 and the vertical square tubes 503 are welded at right angles to form a rectangular square frame structure, which constitutes the basic support structure of the protective mesh. After adding diagonal square tubes 505 and welding them, multiple triangular stabilizing units are formed. The triangular structure can effectively distribute stress and prevent the frame from deforming. The perforated plate is fixed to the surface of the square frame by continuous welding to form an integral protective surface layer. The parallel arrangement of the horizontal square tubes 501 and the vertical square tubes 503 provides evenly distributed connection points for the locking bolts 400, ensuring the connection strength between the protective mesh 500 and the telescopic square tubes 300.

[0057] In practical applications, the horizontal square tube 501 has a fifth mounting hole 502 equidistantly opened along its length direction, which is connected to the mesh connecting support 200 and the telescopic square tube 300 above by locking bolts 400; the longitudinal square tube 503 has a sixth mounting hole 504 equidistantly opened along its length direction, which is detached and connected to the adjacent protective mesh 500 on the left and right by bolts inserted in the sixth mounting hole 504.

[0058] The fifth mounting hole 502 refers to the vertically distributed through holes evenly distributed along the length of the surface of the transverse square tube 501, used to match the insertion position of the locking bolts 500, thereby adjusting the longitudinal height of the protective mesh 500. The sixth mounting hole 504 refers to the transversely distributed through holes evenly distributed along the length of the surface of the longitudinal square tube 501, used for bolt connection with adjacent protective mesh 500, forming a transversely detachable assembly interface.

[0059] Specifically, after aligning the fifth mounting hole 502 of the transverse square tube 501 with the fourth mounting hole 301 of the telescopic square tube 300, the locking bolt passes through both and is tightened, so that the top of the protective mesh 500 and the telescopic square tube 300 form an adjustable rigid connection. The sixth mounting hole 504 of the longitudinal square tube 503 allows adjacent protective mesh 500 to be horizontally spliced ​​by bolts. The bolts can slide within the hole range, so that when the frame column 100 retracts inward, the protective mesh 500 will have relative displacement.

[0060] Furthermore, it is worth noting that, such as Figure 2 As shown, in order to improve the flexibility of the protective net structure and facilitate installation and disassembly, the top of the protective net 500 is connected to the net connecting support 200 with a gap, and the bottom of the protective net 500 is connected to the telescopic square tube 300 and locking bolt 400 of the other set below with a gap, so that the protective nets 500 of the upper and lower adjacent layers are not connected into a whole, thus avoiding mutual interference.

[0061] In some embodiments, this application further proposes that the frame columns 100 on both sides tilt and converge towards the center in the height direction along with the exterior facade of the building structure, causing a plurality of the protective net panels 500 on the protective net assembly to extend and retract inward in the height direction. For example, Figure 4 As shown, the scaffolding columns 100 tilting towards the center means that the two scaffolding columns 100 arranged on both sides are arranged with their upper ends tilted inwards, and they are arranged in accordance with the exterior facade of the building structure. For example, if the exterior facade is a structure that is wider at the bottom and narrower at the top or narrower at the bottom and wider at the top, the scaffolding columns 100 are arranged along the inclined side. Correspondingly, the number of protective netting panels 500 at different heights is arranged reasonably as needed to cover the exterior facade of the building.

[0062] In addition, such as Figure 5 and Figure 6 As shown, since one end of the protective mesh panel 500 in each protective mesh assembly is fixedly connected to the frame column 100 on one side through the telescopic square tube 300, and the other end is overlapped on the frame column 100 through the telescopic square tube 300, the position of the frame column 100 on the other end can be flexibly adjusted as needed, and the spacing between the frame columns 100 on the left and right sides can be adjusted to realize the telescopic change of the protective mesh panel 500 on it.

[0063] In some of these embodiments, such as Figure 1As shown, this application further proposes a column reinforcing rib 600 that connects two adjacent frame columns 100 laterally. The column reinforcing rib 600 is composed of a first reinforcing square tube 601 and a first U-bolt 602. The two ends of the first reinforcing square tube 601 are respectively detachably installed on the outer side wall of the corresponding frame column 100 by nuts through the first U-bolt 602, and are located between the upper and lower mesh connecting supports 200, and are abutting against the back of the protective mesh 500.

[0064] The column reinforcing rib 600 refers to the rigid support component that connects adjacent frame columns 100 laterally. Specifically, it can be implemented using a combination structure of a first reinforcing square tube 601 and a first U-bolt 602. The bending stiffness of the first reinforcing square tube 601 disperses the lateral stress generated by the expansion and contraction of the protective net. The first U-bolt 602 refers to a fastener with a U-shaped bending section, which can be implemented using a metal component with a threaded end.

[0065] Specifically, the first reinforcing square tube 601 is laterally connected to the outer wall of the adjacent frame column 100, and its two ends are connected through the mounting holes on the frame column 100 by the first U-bolt 602 and locked with nuts. The axial stiffness of the first reinforcing square tube 601 can improve the bending resistance of the frame column 100, prevent the frame column 100 from twisting or shifting, thereby improving the structural stability of the protective netting assembly on the two adjacent frame columns 100.

[0066] In some of these embodiments, such as Figure 1 and Figure 2 As shown, this application further proposes a mesh reinforcing rib 700 fixedly installed on the left and right adjacent mesh connecting supports 200. The mesh reinforcing rib 700 is composed of a second reinforcing square tube 701 and a second U-bolt 702. The two ends of the second reinforcing square tube 701 are respectively detachably installed on the third mounting hole 203 on the outer side wall of the corresponding mesh connecting support 200 by nuts through the second U-bolt 702.

[0067] The reinforcing rib 700 refers to the rigid support component that laterally connects adjacent mesh connecting supports 200. Specifically, it can be implemented using a combination of a second reinforcing square tube 701 and a second U-bolt 702. The bending stiffness of the second reinforcing square tube 701 disperses the lateral stress generated by the expansion and contraction of the protective mesh. The second U-bolt 702 is a fastener with a U-shaped bend, which can be implemented using a metal component with a threaded end. The clamping force is adjusted by a nut to accommodate the deformation requirements during the expansion and contraction of the protective mesh.

[0068] Specifically, the second reinforcing square tube 701 is laterally connected to the outer wall of the adjacent mesh connecting support 200, and its two ends are passed through the third mounting hole 203 by the second U-bolt 702 and locked by nuts. The axial stiffness of the second reinforcing square tube 701 can offset the lateral stress generated by the expansion and contraction of the protective mesh 500, and prevent the mesh connecting support 200 from twisting or shifting, thereby improving the structural stability of the connection between the two adjacent mesh connecting supports 200.
