Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to an adjustable aluminum alloy mesh shell temporary support device. Background Technology

[0002] The application of aluminum alloy structures in the construction field is becoming increasingly widespread, especially against the backdrop of green building initiatives. Aluminum alloy grid shell structures, with their lightweight, high strength, and aesthetically pleasing characteristics, are demonstrating enormous development potential. However, aluminum alloy grid shells are spatial grid structures with complex curved shapes and high construction precision requirements, posing significant challenges to temporary support systems. Traditional construction methods typically employ full-span scaffolding or steel frame structures as temporary support systems to meet the installation requirements of aluminum alloy grid shells. These methods have long dominated construction projects, providing fundamental support for the construction of complex spatial structures.

[0003] In actual construction, to adapt to the varying heights and angles of aluminum alloy reticulated shell nodes, existing technologies mainly employ pre-measured and fabricated support members of specific lengths, coupled with customized top support devices to achieve the supporting function. Common methods include arranging full-span scaffolding by precisely calculating node positions, or using welded steel frames to create specialized jigs. The uprights in these scaffolding or jigs then serve as the primary load-bearing components. Additionally, for the curved and inclined sections of the reticulated shell surface, separate top support devices conforming to the surface angle are designed to complement the uprights.

[0004] However, the aforementioned traditional temporary support systems generally suffer from low flexibility. Since the support height and angle are fixed before installation, it is difficult to quickly adjust to new needs if deviations occur on-site. Especially when reuse is required, the support system often needs to be reprocessed or cut to adjust its length, and the top support device also needs to be remade, resulting in significant material waste, low utilization rate, and low construction efficiency. These systems fail to meet the demands of modern building construction for efficient and flexible support systems and require improvement. Utility Model Content

[0005] To address the lack of flexibility in traditional temporary support devices for aluminum alloy mesh shells, this application provides an adjustable temporary support device for aluminum alloy mesh shells.

[0006] This application provides an adjustable temporary support device for aluminum alloy mesh shells, which adopts the following technical solution:

[0007] An adjustable temporary support device for aluminum alloy mesh shell includes a pole with a lifting assembly on the pole. A receiving plate is fixedly connected to the side of the lifting assembly away from the pole, and a support plate is provided on the side of the receiving plate away from the lifting assembly. An angle adjustment component and an angle fixing component are provided between the receiving plate and the support plate.

[0008] By adopting the above technical solution, the coordinated design of the uprights and lifting components enables precise adjustment of the support height. Meanwhile, the angle adjustment and fixing components between the receiving plate and the support plate ensure that the support angle can be freely adjusted and securely locked according to the curved surface of the aluminum alloy mesh shell, thereby guaranteeing reasonable force transmission between the mesh shell and the temporary support. Furthermore, the device has a simple structure, is easy to install and disassemble, significantly shortening construction time and further improving construction efficiency.

[0009] Preferably, the lifting assembly includes a lifting screw that is slidably disposed within the upright and an adjusting block that is rotatably connected to the end of the upright, and the lifting screw is threadedly connected to the adjusting block.

[0010] By adopting the above technical solution, the height of the temporary support device can be flexibly adjusted. The lifting screw is slidably installed inside the upright and is threadedly connected to the adjusting block rotatably connected to the end of the upright. This allows construction personnel to easily adjust the length of the lifting screw extending out of the upright by rotating the adjusting block, thereby achieving precise control of the height of the entire support device.

[0011] Preferably, the adjusting block includes a first block and a second block, which are symmetrically arranged about the upright and are detachably fixedly connected by bolts. Each of the first block and the second block has a snap-fit ​​block fixedly connected to its bottom. The upright has an installation groove, and any snap-fit ​​block is fitted into the installation groove and rotates within the installation groove.

[0012] By adopting the above technical solution, the adjusting block consists of a first block and a second block, which are symmetrical about the upright and detachably fixed together by bolts. This split design facilitates the installation and disassembly of the adjusting block. Simultaneously, the snap-fit ​​blocks on the first and second blocks cooperate with the mounting grooves on the upright, allowing the adjusting block to rotate within the mounting grooves, thereby achieving height adjustment of the lifting screw. This design not only simplifies the assembly process of the adjusting block but also ensures stable rotation of the adjusting block on the upright, improving the accuracy and convenience of height adjustment.

[0013] Preferably, the angle adjusting component includes a connecting column fixedly connected to the side of the receiving plate away from the lifting assembly, and a ball head fixedly connected to the end of the connecting column away from the receiving plate. The angle adjusting component also includes a ball head connector fixedly connected to the side of the support plate near the receiving plate, and the ball head connector and the ball head form a ball joint hinge fit.

[0014] By adopting the above technical solution, the support plate can achieve flexible adjustment at multiple angles. The connecting column provides a stable connection foundation for the ball head connector and the ball head. At the same time, the ball head connector and the ball head form a ball joint hinge, which allows the support plate to rotate around the ball head in multiple directions, thereby adapting to the support needs of aluminum alloy mesh shells in different positions. This effectively solves the problem of fixed angle and difficulty in adjustment of traditional support devices, ensuring that the temporary support and the aluminum alloy mesh shell contact surface are fully in contact, and the force transmission is more reasonable.

[0015] Preferably, the angle fixing component includes a fixing nut and a fixing screw. The fixing nut is fixedly connected to the side of the receiving plate away from the lifting assembly, and the fixing screw passes through the receiving plate and is threadedly connected to the fixing nut. At least three fixing nuts and fixing screws are provided and are distributed in a polygonal array about the connecting post. The end of the fixing screw near the support plate forms an abutment fit with the support plate.

[0016] By adopting the above technical solution, the cooperation of fixing nuts and fixing screws can achieve precise adjustment and stable fixation of the support plate angle. By rotating the fixing screw on the fixing nut, the tilt angle of the support plate can be precisely controlled by the synergistic effect of multiple fixing screws, so as to achieve stable support for complex curved surface nodes. At least three fixing nuts and fixing screws are set to ensure that the stability and reliability of the support plate can be maintained when adjusting the angle of the support plate in multiple directions, thereby adapting to the support needs of aluminum alloy mesh shells in different orientations.

[0017] Preferably, the end of the fixing screw that forms an abutment fit with the support plate is provided with an abutment sleeve.

[0018] By adopting the above technical solution, the abutment sleeve can effectively increase the contact area between the fixing screw and the support plate, thereby increasing the friction between the two and ensuring a more stable and reliable adjustment and fixing of the support plate angle. This avoids slippage or loosening caused by uneven force, and further improves the overall stability of the temporary support device.

[0019] Preferably, an isolation pad is provided on the side of the support plate opposite to the receiving plate.

[0020] By adopting the above technical solution, the isolation pad is set on the side of the support plate away from the receiving plate, which can effectively avoid direct contact between the support plate and the aluminum alloy mesh shell, prevent electrochemical corrosion caused by material differences, and at the same time, the isolation pad can increase the friction between the support plate and the aluminum alloy mesh shell node plate, ensuring that the force transmission between the temporary support device and the mesh shell structure is more reasonable and stable, and improving the overall support effect.

[0021] Preferably, both the support plate and the isolation pad are provided with mounting holes, and the mounting holes are temporarily fixedly connected to the aluminum alloy mesh shell nodes by bolts.

[0022] By adopting the above technical solution, the mounting holes on the support plate and isolation pad can realize the temporary bolt fixing connection with the aluminum alloy mesh shell node, thereby improving the stability of the temporary support device, avoiding displacement or detachment of the support device due to external factors during construction, and ensuring the accuracy and safety of the aluminum alloy mesh shell installation.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The lifting assembly, through the cooperation of the adjusting block and the lifting screw, can flexibly adjust the height of the support device to meet the height requirements of different construction scenarios. The angle adjusting component uses the ball joint and ball connector to form a ball joint hinge to adjust the angle of the support plate. The angle fixing component locks the angle of the support plate through the abutment action of multiple fixing nuts and fixing screws, ensuring that the support device is fully in contact with the aluminum alloy mesh shell during use, which improves the stability and force transmission rationality of the support and reduces the impact of construction errors on installation accuracy.

[0025] 2. The abutment sleeve can effectively increase the contact area between the fixing screw and the support plate, thereby improving the friction between the two and ensuring a more stable and reliable adjustment and fixation of the support plate angle. The isolation pad on the support plate can not only effectively prevent electrochemical corrosion between the aluminum alloy mesh shell and the support device, but also increase the friction between the two and reduce the possibility of relative sliding. In addition, the mounting holes on the support plate and the isolation pad can be temporarily fixed to the aluminum alloy mesh shell node plate by bolts, further enhancing the applicability and reliability of the device.

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.

[0032] This application discloses an adjustable aluminum alloy mesh shell temporary support device.

[0033] Reference Figure 1 and Figure 2 An adjustable aluminum alloy mesh shell temporary support device includes a pole 1 and a lifting assembly 2 on the pole 1. In this embodiment, the lifting assembly 2 includes a lifting screw 21 slidably disposed in the pole 1 and an adjusting block 22 rotatably connected to the end of the pole 1. The lifting screw 21 is threadedly connected to the adjusting block 22. A receiving plate 3 is fixedly connected to the side of the lifting screw 21 away from the pole 1 by welding. A support plate 4 is disposed on the side of the receiving plate 3 away from the lifting screw 21. An angle adjusting member 31 and an angle fixing member 32 are disposed between the receiving plate 3 and the support plate 4.

[0034] In practical use, the lifting screw 21 adopts a 600mm long D36 screw. The lifting screw 21 is slidably designed inside the upright 1 and threadedly connected to the adjusting block 22 at the end of the upright 1. This allows construction personnel to easily adjust the length of the lifting screw 21 extending out of the upright 1 by rotating the adjusting block 22, thereby achieving flexible adjustment of the height of the entire support device. The angle adjusting component 31 and the angle fixing component 32 between the receiving plate 3 and the support plate 4 are combined to ensure that the support angle of the support device can be freely adjusted and securely locked according to the curved surface of the aluminum alloy mesh shell.

[0035] Reference Figure 1 and Figure 2The angle adjusting component 31 includes a connecting post 311 fixedly connected to the side of the receiving plate 3 away from the lifting screw 21 by welding, and a ball head 312 fixedly connected to the end of the connecting post 311 away from the receiving plate 3 by welding. The angle adjusting component 31 also includes a ball head connector 313, which is fixedly connected to the side of the support plate 4 near the receiving plate 3 by welding. The ball head connector 313 and the ball head 312 form a ball joint hinge. In actual use, the connecting post 311 provides a stable connection foundation for the ball head connector 313 and the ball head 312. At the same time, the ball head connector 313 and the ball head 312 form a ball joint hinge, which allows the support plate 4 to rotate around the ball head 312 in multiple directions.

[0036] Reference Figure 1 and Figure 2 The angle fixing component 32 includes a fixing nut 321 and a fixing screw 322. The fixing nut 321 is fixedly connected to the side of the receiving plate 3 away from the lifting screw 21 by welding. The fixing screw 322 passes through the receiving plate 3 from the side away from the support plate 4 and is threadedly connected to the fixing nut 321. The end of the fixing screw 322 near the support plate 4 forms an abutment fit with the support plate 4, and a rubber abutment sleeve 323 is sleeved on the end of the fixing screw 322 that forms an abutment fit with the support plate 4. In this embodiment, the fixing nut 321 is provided with There are four fixing screws 322 and four fixing nuts 321 corresponding to the fixing screws 322 and the abutment sleeves 323, which are arranged in a square array around the connecting column 311 on the receiving plate 3. In actual use, by rotating the fixing screws 322 on the side of the receiving plate 3 away from the support plate 4, and by utilizing the synergistic effect of multiple fixing screws 322, the tilt angle of the support plate 4 can be precisely controlled to achieve stable support for complex curved surface nodes. The abutment sleeves 323 can effectively increase the contact area between the fixing screws 322 and the support plate 4, thereby improving the friction between the two.

[0037] Reference Figure 3 and Figure 4The adjusting block 22 includes a first block 221 and a second block 222, which are symmetrically arranged about the upright 1. The first block 221 and the second block 222 form a closed ring structure and are detachably fixedly connected by bolts. A snap-fit ​​block 223 is welded to the bottom of both the first block 221 and the second block 222. An annular mounting block 11 is welded to the outer side of the end of the upright 1, and an annular mounting groove 12 is formed on the outer side of the mounting block 11. Each of the snap-fit ​​blocks 223... The adjusting block 22 is fitted into the mounting groove 12 and rotates within the mounting groove 12. In actual use, the adjusting block 22 is composed of a first block 221 and a second block 222 and is detachably fixed by bolts, making the adjusting block 22 easy to install and remove. At the same time, the snap-fit ​​block 223 welded on the first block 221 and the second block 222 is fitted into the mounting groove 12 on the mounting block 11 and rotates within the mounting groove 12, so that the adjusting block 22 can rotate stably at the end of the upright 1, thereby realizing the precise height adjustment of the lifting screw 21.

[0038] Reference Figure 1 A rubber isolation pad 5 is provided on the side of the support plate 4 away from the receiving plate 3. In this embodiment, the isolation pad 5 is fixedly connected to the support plate 4 by adhesive. Both the support plate 4 and the isolation pad 5 have reserved mounting holes 6. The mounting holes 6 are temporarily fixed to the aluminum alloy mesh shell node by bolts. In this embodiment, M10-60 bolts are used to temporarily fix the aluminum alloy mesh shell node by passing through the reserved mounting holes 6. In actual use, the isolation pad 5 can effectively prevent the support plate 4 from directly contacting the aluminum alloy mesh shell, preventing electrochemical corrosion problems caused by material differences. The reserved mounting holes 6 on the support plate 4 and the isolation pad 5 can realize the temporary fixed connection with the aluminum alloy mesh shell node by bolts, thereby improving the stability of the temporary support device.

[0039] The implementation principle of this application embodiment is as follows: the lifting screw 21, which is slidably set in the upright 1, forms a threaded engagement with the adjusting block 22, which is rotatably connected to the end of the upright 1. This allows the construction personnel to conveniently adjust the length of the lifting screw 21 extending out of the upright 1 by rotating the adjusting block 22, thereby realizing flexible adjustment of the height of the support device. The adjusting block 22 is composed of a first block 221 and a second block 222 and is detachably fixed by bolts, which facilitates the installation and disassembly of the adjusting block 22. The snap-fit ​​blocks 223 on the first block 221 and the second block 222 cooperate with the mounting groove 12 on the upright 1 to ensure the stable rotation of the adjusting block 22 on the upright 1, thereby improving the accuracy and convenience of height adjustment.

[0040] Meanwhile, the receiving plate 3 and the support plate 4 are connected by a ball joint 312 and a ball joint connector 313 to form a ball joint hinge, enabling multi-directional angle adjustment. Four sets of fixing nuts 321 and fixing screws 322, distributed around the connecting column 311, form an abutment fit with the side of the support plate 4 closest to the receiving plate 3, thereby precisely controlling the tilt angle of the support plate 4 and achieving stable support for complex curved surface nodes. The rubber abutment sleeve 323 effectively increases the contact area between the fixing screw 322 and the support plate 4, thereby increasing the friction between them and preventing slippage or loosening due to uneven force. The isolation pad 5 on the support plate 4 effectively prevents direct contact between the support plate 4 and the aluminum alloy mesh shell, preventing electrochemical corrosion problems caused by material differences. Combined with the reserved mounting holes 6, temporary bolted connections to the aluminum alloy mesh shell nodes can be achieved, thereby improving the stability of the temporary support device.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
