DETAILED DESCRIPTION

[0042] Example 1

[0043] like Figure 1-3 As shown, an assembled arch rib assembly bracket includes two supporting towers 2 arranged on a foundation 1. The heights of the two supporting towers 2 correspond to the heights of the support points of the assembled arch ribs 4, respectively, so as to match the support points of the assembled arch ribs 4 at different positions and heights. An inter-tower connection system 3 is provided between the two supporting towers 2. The inter-tower connection system 3 can be used to form an integral supporting structure of the two supporting towers 2, thereby preventing a single tower from tilting or displacing due to lateral force or wind load, and thus providing stable support for the installation of the assembled arch ribs 4 during the construction process.

[0044] A plurality of guy ropes 5 are also provided on the outside of the supporting tower 2. One end of the guy rope 5 is connected to the standard steel structure section 21 or the non-standard steel structure section 220 located above through a rope clamp, and the other end is connected to the foundation 1 through a lifting lug, thereby further improving the overall wind resistance.

[0045] The support tower 2 includes a foundation connection conversion device 20 connected to the foundation 1, standard steel structure segments 21 arranged sequentially on the foundation connection conversion device 20, and a height adjustment segment 22 provided on the topmost standard steel structure segment 21. The foundation connection conversion device 20 is used to achieve a stable connection between the support tower 2 and the foundation 1; the standard steel structure segment 21 is a frame structure composed of multiple standard steel sections and is stacked and assembled in a modular manner to achieve rapid construction of support towers of different heights. In this embodiment, the standard steel structure segments 21 are connected by bolts for easy disassembly and reuse; the height adjustment segment 22 is used to accurately adjust the height of the support tower to match the elevation of the assembled arch rib, which specifically includes:

[0046] The non-standard steel structure segment 220 is arranged on the topmost standard steel structure segment 21. The non-standard steel structure segment 220 is also a frame structure spliced ​​by multiple standard steel sections. The tops of its four vertical poles form a corresponding height difference along the axial direction of the prefabricated arch rib 4 to match the spatial curve of the arch rib, and two support beams 221 are arranged perpendicular to the axial direction of the prefabricated arch rib 4. The support beams 221 serve as the direct support structure of the arch rib segment. The support beams 221 are provided with multiple adjustment blocks 222 for supporting the prefabricated arch rib 4. In this embodiment, the number of adjustment blocks 222 on a single support beam 221 is two, and the left and right supports are arranged below the prefabricated arch rib 4 for its installation. The vertical poles, support beams 221 and adjustment blocks 222 are fixed by bolts.

[0047] It should be noted that when in use, the height of the adjustment block is simulated through a 3D model, and is processed and fixed to the beam in advance to accurately adjust the elevation and line shape of the arch rib, and then the arch rib is hoisted so that it falls on the adjustment block. In addition, walkway boards are laid between the supporting beams 221, and guardrails are set up as a working platform for welding the webs between the arch rib segments.

[0048] The prefabricated arch rib assembly bracket of this embodiment can meet the assembly requirements of complex-shaped arch ribs, provide an efficient, stable, and adjustable modular construction support system, effectively improve construction efficiency and ensure project quality. At the same time, the segments are connected by bolts, avoiding damage to standard sections caused by welding, facilitating installation and turnover, and increasing material life and turnover times.

[0049] Example 2

[0050] Further illustrate with reference to Example 1, Figure 4-7In the structure shown, the foundation connection conversion device 20 is composed of two supporting units, which provide stable support for the standard steel structure section 21 at the bottom, thereby realizing a reliable connection between the supporting tower 2 and the foundation 1. The supporting unit includes a pad beam 200 rigidly connected to the foundation 1. The pad beam 200 can be fixed to the foundation 1 by embedded bolts or welding. Two connection conversion parts 201 are provided on the pad beam 200. The four connection conversion parts 201 of the two supporting units correspond to the four columns of the standard steel structure section 21 at the bottom, respectively. The pad beam 200 effectively expands the overall force-bearing area, and through the reasonable arrangement of the connection conversion parts 201, the vertical load of the tower is evenly distributed to the foundation 1, avoiding excessive local force on the foundation, and through the reasonable arrangement of the position between the pad beam 200 and the connection conversion parts 201, the center of gravity of the entire tower is stable and the force is evenly distributed, avoiding tilting or displacement of the bottom of the tower.

[0051] In the preferred embodiment, the connection conversion member 201 includes an I-shaped pad 2010, and a cover plate 2011 is provided on the top of the I-shaped pad 2010. The cover plate 2011 is provided with fixing holes 2012 corresponding to the column bolt holes of the standard steel structure section 21. The shape characteristics of the I-shaped pad 2010 facilitate the setting of the fixing holes 2012 and the installation of the nuts.

[0052] In the preferred embodiment, the pad beam 200 is composed of a single I-beam or a combination of multiple I-beams, and U-shaped sliding limiters 2013 are provided on both sides of the I-shaped pad block 2010. The U-shaped sliding limiters 2013 slide and wrap the flange above the pad beam 200 therein, so that the connecting conversion member 201 can slide linearly on the pad beam 200, thereby adjusting its specific support position to meet the spacing requirements between the columns of the standard steel structure section 21.

[0053] Sliding grooves 2000 are provided on both side flanges above the pad beam 200. The sliding grooves 2000 are long slots processed on the flanges of the pad beam and arranged along the longitudinal direction of the pad beam to cooperate with the sliding and positioning of the connecting conversion part 201. The length of the sliding groove is designed to meet the range requirements that may be adjusted during construction, ensuring that the connecting conversion part can slide freely and be fixed within the linear range.

[0054] The U-shaped sliding limiter 2013 is provided with a locking groove 2014 on the lower side panel, and a through hole 2015 is provided on the upper side panel, in which a locking bolt 2018 is inserted. The insertion end of the locking bolt 2018 passes through the sliding groove 2000 and the locking groove 2014 in sequence, and is threadedly installed with a locking nut 2019. The locking nut 2019 can contact the bottom of the upper flange of the pad beam 200 through the locking groove 2014.

[0055] With this design, after the locking nut 2019 is released from contact with the bottom of the upper flange of the pad beam 200, the distance between the two connecting conversion parts 201 can be adjusted by sliding. After the adjustment is completed, the locking effect is achieved by tightening the locking nut 2019 to make it contact with the flange of the pad beam 200.

[0056] In the preferred embodiment, the bottom of the U-shaped sliding limiter 2013 is also provided with a support plate 2016 that is compatible with the side groove of the pad beam 200. Except for the upper edge, the other three edges of the support plate 2016 are provided with support reinforcements 2017 extending to the side. The support plate 2016 and the support reinforcements 2017 are used to effectively increase the contact area between the pad beam 200 and the U-shaped sliding limiter 2013, effectively disperse the vertical load transmitted by the structure, and also play the role of supporting the flange structure of the pad beam 200, further enhancing the stability and bearing performance of the overall structure, and avoiding problems caused by force concentration or lateral displacement.

[0057] Example 3

[0058] Further illustrate with reference to Example 2, Figure 8-9 As shown in the structure, in order to further improve the spacing adjustment accuracy of the two connecting conversion parts 201, the cushion beam 200 in this embodiment is composed of two I-beams, and a spacing adjustment mechanism 202 for adjusting the spacing between the two connecting conversion parts 201 is provided in the cavity connecting the two, and a movable groove 2001 connected thereto is provided at the top of the cavity.

[0059] Among them, the spacing adjustment mechanism 202 includes an axle seat 2020 hoisted at both ends of the cavity, and a positive and negative thread screw 2021 is rotatably arranged between the bearings of the two axle seats 2020. One end of the positive and negative thread screw 2021 passes through the axle seat 2020 and is connected to a rotating hand plate 2022, so that the positive and negative thread screw 2021 can be rotated between the two axle seats 2020 by rotating the hand plate 2022.

[0060] A connecting plate 2023 passing through the movable groove 2001 is provided at the bottom of the I-shaped pad 2010. The connecting plate 2023 is mounted on the corresponding threads of the positive and negative thread screws 2021 through the internal thread sleeve 2024 provided thereon, so that the precise adjustment of the distance between the two connecting conversion parts 201 is achieved through the forward and reverse rotation of the positive and negative thread screws 2021.

[0061] Example 4

[0062] Further illustrate with reference to Example 1, Figure 10-16In the structure shown, the inter-tower connection system 3 includes a plurality of hoop structures 30 arranged on the columns of the standard steel structure section 21 on the opposite sides of the two supporting towers 2. A plurality of parallel connecting rods 31 and diagonal braces 32 are arranged between the two supporting towers 2 through the hoop structures 30, wherein the parallel connecting rods 31 are used to provide a transverse connection between the two supporting towers 2, and their main function is to enhance the horizontal rigidity between the towers. The diagonal braces 32 connect the two supporting towers 2 through a certain inclination angle, and are mainly used to enhance the anti-overturning ability and overall stability between the towers.

[0063] It should be noted that both the parallel connecting rods 31 and the diagonal bracing rods 32 are made of high-strength steel, and their lengths meet the height and spacing requirements of the two supporting towers 2 .

[0064] In this embodiment, there are two inter-tower connection systems 3 , which are arranged front and back between two supporting towers 2 .

[0065] In the preferred embodiment, the clamp structure 30 includes two symmetrically arranged U-shaped docking pieces 300, and both ends of the U-shaped docking piece 300 are provided with outwardly extending docking plates 301, and a plurality of docking screws 302 are provided on the docking plate 301 of one of the U-shaped docking pieces 300, and docking holes 303 matching the docking screws 302 are provided on the docking plate 301 of the other U-shaped docking piece 300. The ends of the docking screws 302 pass through the corresponding docking holes 303 and are threadedly fitted with docking nuts 304. In this embodiment, the number of docking screws 302 on a single docking plate 301 is three. When in use, the docking screws 302 are inserted into the corresponding docking holes 303 and the docking nuts 304 are installed to achieve a locking effect, thereby ensuring that the two U-shaped docking pieces 300 firmly hold the columns.

[0066] The side of one of the U-shaped docking parts 300 is also provided with multiple connecting ears 305 for connecting the parallel connecting rod 31 and the diagonal support rod 32. The connecting ears 305 are provided with mounting holes for connecting the parallel connecting rod 31 and the diagonal support rod 32 through a pin shaft. In this embodiment, the number of connecting ears 305 is three, which can connect one parallel connecting rod 31 and two diagonal support rods 32 at the same time.

[0067] In the preferred embodiment, in order to improve the stability of the two U-shaped docking parts 300 during the installation process, a groove 306 is provided on the outside of the docking nut 304, a ratchet 307 is provided in the groove 306, and a pawl assembly 308 cooperating with the ratchet 307 is provided at the docking hole 303. Through the cooperation between the ratchet 307 and the pawl assembly 308, the clamping posture can be maintained when the two U-shaped docking parts 300 are not locked.

[0068] With this design, when the two U-shaped docking parts 300 are docked and clamped to the vertical pole, the ratchet 307 and the pawl assembly 308 can be used to keep the two in a clamping posture when the docking nut 304 is not installed, so that the installation height can be maintained. There is no need for construction workers to maintain its position when installing the docking nut 304, which greatly improves its installation convenience.

[0069] In the preferred embodiment, the pawl assembly 308 includes a through ring 3030 arranged at the docking hole 303, the inner diameter of the through ring 3030 is the same as the diameter of the docking hole 303, a telescopic groove 3031 is provided on the inner side of the through ring 3030, and a through hole 3032 connected to the telescopic groove 3031 is provided on the outer side, and a telescopic rod 3033 is telescopically provided through the through hole 3032 and the telescopic groove 3031, and a limit plate 3034 and a pawl 3035 are respectively provided at both ends of the telescopic rod 3033, the diameter of the limit plate 3034 is larger than the diameter of the through hole 3032, the pawl 3035 can pass through the telescopic groove 3031 and adapt to the ratchet 307, and the outside of the telescopic rod 3033 is provided with a return spring 3036 located between the telescopic groove 3031 and the pawl 3035.

[0070] With this design, a guide path can be provided for the movement of the telescopic rod 3033 and the pawl 3035 through the docking hole 303, and the limit plate 3034 plays a limiting role. When the telescopic rod 3033 passes through the through ring 3030, the pawl 3035 telescopes and moves through contact with the ratchet 307 and under the action of the return spring 3036. When it moves to the extreme position, the interference between the pawl 3035 and the ratchet 307 effectively prevents the telescopic rod 3033 from detaching.

[0071] Furthermore, rubber pads 309 are provided on the inner sides of the two U-shaped docking pieces 300. The elasticity of the rubber pads 309 and the locking of the pawl assembly 308 and the ratchet 307 can further enhance the anti-slip performance and stability, while preventing the U-shaped docking pieces from scratching the surface of the tower column.

[0072] The telescopic rod 3033 and the pawl 3035 are rotatably connected, wherein a T-slot 3039 is provided at the connection between the pawl 3035 and the telescopic rod 3033 , and a T-shaped connector 3038 movably disposed in the T-slot 3039 is provided at the end of the telescopic rod 3033 .

[0073] The through hole 3032 is a threaded hole, and a thread 3037 adapted to the threaded hole is provided at one end of the telescopic rod 3033 close to the pawl 3035 .

[0074] With this design, when dismantling, the pawl 3035 can be pulled out of the pawl 3035 through the telescopic rod 3033 to release the interference between the two, and the telescopic rod 3033 can be rotated to be threadedly connected to the through hole 3032 to maintain its unlocked state.
