Description

Technical Field

[0001] This invention relates to the field of communication construction technology, and more specifically, to a modular, rapid construction prefabricated steel foundation structure for communication towers and its installation method. Background Technology

[0002] Existing communication towers are mainly divided into single-tube towers, lattice towers, support poles, and guyed towers. Among them, single-tube towers and lattice towers account for the majority of applications. A single-tube tower is a self-supporting tall steel structure made of a single steel pipe, and its main body is mostly welded steel pipe with a circular or polygonal cross-section. A lattice tower is a pole structure tower with steel sections or steel pipes as the main material, connected by web members to form an integral structure. It is generally triangular or quadrilateral. A support pole is a tall steel structure made of a vertical single tube or lattice structure (tower body) plus a support system. Its tower body is mostly welded steel pipe with a circular or polygonal cross-section. A guyed tower is a tall steel structure made of columns and guy wires (cables), also known as a mast. All of these signal towers require a prefabricated steel foundation structure as the load-bearing part below ground.

[0003] Existing technologies for prefabricated steel foundations for communication towers typically consist of modular components such as segmented steel piles and composite foundations. While these structures can be pre-installed and assembled on-site, once assembled, they are fixed and cannot be folded. Consequently, they occupy significant space during transportation, making transport inconvenient and increasing transportation difficulty and costs. Further disassembly, while facilitating transportation, leads to cumbersome on-site assembly, reducing on-site assembly efficiency and further decreasing construction efficiency. Summary of the Invention

[0004] This invention provides a modular, rapid construction method for prefabricated steel foundations for communication towers, addressing the problems of existing prefabricated steel foundations for communication towers occupying large spaces after fixing, leading to transportation difficulties and increased transportation costs, and further disassembly resulting in cumbersome on-site assembly and reduced construction efficiency.

[0005] To address the aforementioned problems, according to one aspect of the present invention, a modular, rapid-construction precast steel foundation structure for communication towers is provided, comprising: multiple columns, multiple fixed connection mounting plates fixedly connected to the upper and lower ends of the multiple columns, multiple connecting plates detachably connected between the upper and lower fixed connection mounting plates, the connecting plates being used to connect the multiple columns, multiple foldable and unfoldable folding frame mechanisms being arranged circumferentially on the multiple fixed connection mounting plates, a stabilizing mechanism being arranged inside the folding frame mechanism, the stabilizing mechanism being used to stabilize the folding frame mechanism, and a triangular frame mechanism being arranged between every two adjacent folding frame mechanisms.

[0006] Furthermore, there are three columns and three folding frame mechanisms. Six connecting plates are detachably connected between multiple fixed connecting mounting plates at the top and bottom. The folding frame mechanism includes four connecting mounting plates, one end of which is detachably connected to the outside of the fixed connecting mounting plates.

A pin is fixedly connected to the middle of the limit ring. A return spring is installed inside the mounting cylinder. A limit plate is fixedly connected to the top of one of the vertical plates. The pin is inserted into the inside of the limit plate.

[0007] Furthermore, the stabilizing mechanism includes multiple mounting components. Support rods are provided at each of the four corners of the mounting components. Through slots are formed inside the support rods. Fixing pins are fixedly connected to the interior of each of the four corners of the mounting components, and these fixing pins are located inside the through slots. A sliding sleeve is rotatably connected to the end of the support rod furthest from the mounting component. A slot is formed on the outer wall of the sliding sleeve. A movable column is slidably connected to the middle of the mounting component. A tension spring is installed inside the movable column. A fixing ring is fixedly connected to the outside of the movable column. Four fixing plates are fixedly connected to the outside of the fixing ring. Insert rods are fixedly connected to the side of the fixing plates closest to the mounting component. Support columns are provided between the interiors of the upper and lower sliding sleeves. Locking blocks are fixedly connected to both ends of the support columns, and the slots engage with the locking blocks. Both ends of the support columns are detachably connected between the two frame assembly plates. Insert rods are inserted into the interior of the support rods. A pull handle is fixedly connected to the outside of the fixing ring, and the insert rods are slidably connected inside the mounting component.

[0008] Furthermore, one end of the tension spring is fixedly connected to the inside of the mounting component, and the other end of the tension spring is fixedly connected to the inside of the movable column.

[0009] Furthermore, the triangular frame mechanism includes four I-beams, four rotating steel plates, and four rotating outer edge steels. One end of each of the four I-beams is detachably connected to the outside of two fixed connecting mounting plates. Two connecting steel plates are detachably connected between the four I-beams. Both ends of the rotating steel plates and the rotating outer edge steels are fixedly connected to end cylinders. The end cylinders are equipped with supporting springs. Two hexagonal limit blocks are slidably connected inside the end cylinders. The end of each hexagonal limit block away from the supporting spring is fixedly connected to a threaded pin. One end of each rotating steel plate and the rotating outer edge steel is rotatably connected to the inside of the I-beams through threaded pins. The other end of each rotating steel plate and the rotating outer edge steel is rotatably connected to the inside of the connecting mounting plates through threaded pins.

[0010] Furthermore, the two ends of the supporting spring are respectively fixedly connected to one end of the two hexagonal limiting blocks, a support frame one is fixedly connected between the upper and lower two rotating outer edge steels, a support frame two is fixedly connected between the upper and lower two rotating steel plates, and a base plate is fixedly connected between the bottom of the two lower rotating outer edge steels and the bottom of the three frame assembly plates.

[0011] Furthermore, multiple inner connecting tubes are fixedly connected to the side of the six frame assembly plates near the connecting plates, and outer connecting tubes are fixedly connected to the side of the six connecting plates near the frame assembly plates. The inner connecting tubes are detachably connected inside the outer connecting tubes.

[0012] Furthermore, one end of the return spring is fixedly connected to the inside of the mounting cylinder, and the other end of the return spring is fixedly connected to the outside of the limit ring.

[0013] Furthermore, a reset spring is sleeved on the outside of the insertion post, and a pull ring is fixedly connected to the end of the insertion post away from the limiting plate.

[0014] According to another aspect of the present invention, an installation method is provided for the above-mentioned modular rapid construction prefabricated steel foundation structure of a communication tower, comprising the following steps:

[0015] Step 1: Unfold the folding frame mechanism and secure the bolts on the folding frame mechanism. At the same time, unfold the stabilizing mechanism and lock the stabilizing mechanism.

[0016] Step 2: Use the fixed connection mounting plate to install the unfolded folding frame mechanism from Step 1 onto the outside of the column, and then pre-install the three triangular frame mechanisms between the three folding frame mechanisms.

[0017] Step 3: Fix the triangular frame mechanism pre-installed on the folding frame mechanism in Step 2, and then use the fixed connection mounting plate to install and fix the triangular frame mechanism to the column.

[0018] The modular, rapid construction prefabricated steel foundation structure and installation method for communication towers provided by this invention have the following technical advantages:

[0019] 1. This invention divides the basic structure into a folding frame mechanism, a stabilizing mechanism, and a triangular frame mechanism, all of which can be folded. This reduces the transportation space required during transport, thereby facilitating transportation and reducing transportation costs. It also avoids further disassembly and cumbersome on-site assembly, further improving on-site assembly efficiency and thus enhancing construction efficiency.

[0020] 2. This invention enables the pre-installation of the folding frame mechanism, stabilizing mechanism, and triangular frame mechanism, thereby enabling the rapid construction of a basic frame. By fixing the bolts on the basis of the basic frame, the basic structure can be completed. Because it can be formed quickly, it is easier to assemble after forming, thereby improving the assembly efficiency and construction efficiency. Attached Figure Description

[0037] The technical solutions in at least one embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one embodiment is merely illustrative and is not intended to limit this application or its applications. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.

[0038] like Figures 1 to 10 As shown, an embodiment of the present invention provides a modular, rapid-construction precast steel foundation structure for a communication tower, comprising: multiple columns 1, multiple fixed connection mounting plates 2 fixedly connected to the upper and lower ends of the multiple columns 1, multiple connecting plates 3 detachably connected between the upper and lower fixed connection mounting plates 2, the connecting plates 3 being used to connect the multiple columns 1, multiple foldable and unfoldable folding frame mechanisms 4 being arranged circumferentially on the multiple fixed connection mounting plates 2, a stabilizing mechanism 5 being arranged inside the folding frame mechanism 4, the stabilizing mechanism 5 being used to stabilize the folding frame mechanism 4, and a triangular frame mechanism 6 being arranged between every two adjacent folding frame mechanisms 4.

[0039] Applying the technical solution of this embodiment, the modular rapid construction communication tower prefabricated steel foundation structure includes multiple columns 1. Multiple fixed connection mounting plates 2 are fixedly connected to the upper and lower ends of each column 1. These fixed connection mounting plates 2 are detachably connected via multiple connecting plates 3, thus constructing a stable column group support frame. Multiple foldable and unfoldable folding frame mechanisms 4 are arranged circumferentially on the multiple fixed connection mounting plates 2. These folding frame mechanisms 4 can be folded during transportation to significantly reduce the overall volume and quickly unfolded during on-site construction to form an outer support structure, reducing transportation space occupation. A stabilizing mechanism 5 is provided inside the folding frame mechanism 4. This stabilizing mechanism 5 provides internal rigid support and anti-deformation capacity after the folding frame mechanism 4 is unfolded, ensuring the structure maintains geometric stability when bearing tower loads. A triangular frame mechanism 6 is provided between every two adjacent folding frame mechanisms 4. This triangular frame mechanism 6 enhances the overall structure's resistance to lateral forces through the principle of geometric stability and works in conjunction with the folding frame mechanism 4 and the stabilizing mechanism 5 to form a three-dimensional spatial rigid network. Through the coordinated operation of the folding frame mechanism 4, the stabilizing mechanism 5, and the triangular frame mechanism 6, the entire foundation structure can be folded and stored as a whole during transportation without the need to disassemble multiple parts. Once on site, it only needs to be unfolded and locked to quickly form a complete load-bearing foundation. This solves the technical problems of traditional communication tower steel prefabricated foundations, which occupy a large transportation space and have low on-site splicing efficiency due to their non-foldability.

[0040] like Figure 1 and Figure 2 As shown, there are three columns 1 and three folding frame mechanisms 4. Six connecting plates 3 are detachably connected between multiple fixed connecting mounting plates 2. The folding frame mechanism 4 includes four connecting mounting plates 401. One end of the connecting mounting plate 401 is detachably connected to the outside of the fixed connecting mounting plate 2. Four frame assembly plates 402 are rotatably connected between the four connecting mounting plates 401. A stabilizing frame 403 is detachably connected between the upper and lower connecting mounting plates 401. Multiple vertical plates 404 are rotatably connected between the upper and lower frame assembly plates 402. An inclined plate 405 is detachably connected between the upper and lower frame assembly plates 402. An installation cylinder 408 is fixedly connected to the bottom of one of the upper frame assembly plates 402. A limit ring 409 is slidably connected inside the installation cylinder 408. An insert post 410 is fixedly connected to the middle of the limit ring 409. A return spring 411 is provided inside the installation cylinder 408. A limit plate 412 is fixedly connected to the top of one of the vertical plates 404. The insert post 410 is inserted into the inside of the limit plate 412.

[0041] When the folding frame mechanism 4 unfolds from the folded state to the working position, the vertical plate 404 rotates to the vertical state along with the frame assembly plate 402. The limiting plate 412 fixed to its top moves to align with the insertion post 410. The return spring 411 pushes the limiting ring 409 to slide axially along the mounting cylinder 408, so that the insertion post 410 automatically inserts into the hole groove of the limiting plate 412, thereby achieving mechanical locking of the unfolding angle of the vertical plate 404. This effectively prevents shrinkage deformation caused by external force or its own weight, thus maintaining the overall unfolding configuration of the folding frame mechanism 4 without the need for additional fasteners, improving on-site assembly efficiency and structural stability.

[0042] like Figure 3 As shown, the stabilizing mechanism 5 includes multiple mounting components 501. Support rods 502 are provided at each of the four corners of the mounting components 501. Through slots 514 are formed inside the support rods 502. Fixing pins 513 are fixedly connected to the interior of each of the four corners of the mounting components 501, and are located inside the through slots 514. A sliding sleeve 503 is rotatably connected to the end of the support rod 502 away from the mounting component 501. A slot 504 is formed on the outer wall of the sliding sleeve 503. A movable column 505 is slidably connected to the middle of the mounting component 501. A tension spring 506 is provided inside the movable column 505, and a fixing ring 5 is fixedly connected to the outside of the movable column 505. 07. The fixing ring 507 is externally fixedly connected to four fixing plates 508. The fixing plates 508 are fixedly connected to the side of the mounting part 501 with a plug rod 509. The upper and lower sliding sleeves 503 are both provided with support columns 510. The two ends of the support column 510 are fixedly connected to the locking blocks 511. The locking slots 504 are engaged with the locking blocks 511. The two ends of the support column 510 are detachably connected between the two frame assembly plates 402. The plug rod 509 is inserted into the inside of the support rod 502. The fixing ring 507 is externally fixedly connected to a pull handle 512. The plug rod 509 is slidably connected to the inside of the mounting part 501.

[0043] In this embodiment, when the folding frame mechanism 4 is in the unfolded state, the two ends of the support column 510 are respectively connected to two frame assembly plates 402 to form a rigid support skeleton. At the same time, the locking blocks 511 at both ends of the outer wall of the support column 510 engage with the locking grooves 504 on the outer wall of the sliding sleeve 503 to achieve lateral limitation and prevent the folding frame mechanism 4 from retracting or deforming under force. At this time, the insertion rod 509 slides along the inside of the mounting part 501 and inserts into the support rod 502 under the elastic force of the tension spring 506, forming a longitudinal lock on the support rod 502. The support rod 502 is adjustable in the through groove 514 by the fixing pin 513. Rotation allows the entire stabilizing mechanism 5 to automatically adapt to the posture of the frame assembly plate 402, ensuring structural stability. When folding is required, pulling the handle 512 drives the fixing ring 507 and the movable column 505 to overcome the elastic force of the tension spring 506, causing the insertion rod 509 to exit from the support rod 502, releasing the longitudinal lock. At the same time, the locking block 511 separates from the locking groove 504, and the support column 510 can be detached, allowing the folding frame mechanism 4 to return to the folded state, facilitating transportation and rapid on-site assembly. This structure, through a dual locking mechanism of locking and insertion, enhances the overall basic structure's resistance to deformation and installation reliability in the unfolded state.

[0044] like Figure 6 As shown, one end of the tension spring 506 is fixedly connected to the inside of the mounting part 501, and the other end of the tension spring 506 is fixedly connected to the inside of the movable column 505. When one end of the tension spring 506 is fixedly connected to the inside of the mounting part 501 and the other end is fixedly connected to the inside of the movable column 505, if the handle 512 is released, the tension spring 506 will use its preset elastic force to drive the movable column 505 to reset towards the mounting part 501, thereby causing the insertion rod 509, which is fixedly connected to the outside of the movable column 505, to automatically slide along the inside of the mounting part 501 and insert into the through groove 514 of the support rod 502, realizing the self-locking engagement between the insertion rod 509 and the support rod 502. This reset action works in conjunction with the locking structure between the slot 504 on the outer wall of the sliding sleeve 503 and the locking blocks 511 at both ends of the support column 510, to maintain the unfolded state of the stabilizing mechanism 5 without the need for an additional locking device, ensuring the structural stability of the folding frame mechanism 4 during construction.

[0045] like Figure 9As shown, the triangular frame mechanism 6 includes four I-beams 601, four rotating steel plates 603, and four rotating outer edge steels 604. One end of each of the four I-beams 601 is detachably connected to the outside of two fixed connecting mounting plates 2. Two connecting steel plates 602 are detachably connected between the four I-beams 601. Both ends of the rotating steel plates 603 and the rotating outer edge steels 604 are fixedly connected to end cylinders 605. A supporting spring 606 is provided inside the end cylinder 605. Two hexagonal limiting blocks 607 are slidably connected inside the end cylinder 605. A threaded pin 608 is fixedly connected to the end of the hexagonal limiting block 607 away from the supporting spring 606. One end of each rotating steel plate 603 and rotating outer edge steel 604 is rotatably connected to the inside of the I-beams 601 through the threaded pin 608. The other ends of each rotating steel plate 603 and rotating outer edge steel 604 are rotatably connected to the inside of the connecting mounting plate 401 through the threaded pin 608.

[0046] During on-site installation, align the end cylinder 605 with the corresponding holes on the I-beam 601 and the connecting mounting plate 401, then release the threaded pin 608. The support spring 606 will quickly reset and push the hexagonal limit block 607 outward, allowing the threaded pin 608 to automatically insert into the hole for pre-positioning. No manual assistance is required for hole alignment, significantly shortening the installation time. Then, tighten the nut on the threaded pin 608 to complete the rigid fixation. This structure ensures the compactness of folding and transportation while achieving rapid self-locking and stable connection between the triangular frame mechanism 6, the column 1, and the folding frame mechanism 4, improving on-site assembly efficiency and structural integrity.

[0047] like Figure 10 As shown, the two ends of the supporting spring 606 are respectively fixedly connected to one end of the two hexagonal limiting blocks 607. A support frame 609 is fixedly connected between the upper and lower rotating outer edge steels 604. A support frame 610 is fixedly connected between the upper and lower rotating steel plates 603. A base plate 7 is fixedly connected between the bottom of the two lower rotating outer edge steels 604 and the bottom of the three frame assembly plates 402.

[0048] A support frame 609 is fixedly connected between the upper and lower rotating outer edge steels 604, and a support frame 610 is fixedly connected between the upper and lower rotating steel plates 603. When the rotating outer edge steels 604 and the rotating steel plates 603 are folded, they form a rigid constraint frame through the support frame 609 and the support frame 610, which effectively prevents structural deformation or component scattering and improves the overall stability during transportation. The bottom of the two lower rotating outer edge steels 604 and the bottom of the three frame assembly plates 402 are fixedly connected to a base plate 7, so that the triangular frame mechanism 6 and the folding frame mechanism 4 together form a continuous and unified bottom support plane after installation and unfolding. This ensures that the foundation structure is evenly stressed, avoids local stress concentration, and enhances the overall resistance to settlement and overturning.

[0049] like Figure 3 As shown, multiple inner connecting tubes 406 are fixedly connected to the side of the six frame assembly plates 402 near the connecting plate 3, and outer connecting tubes 407 are fixedly connected to the side of the six connecting plates 3 near the frame assembly plates 402. The inner connecting tubes 406 are detachably connected inside the outer connecting tubes 407. This plug-in structure enables the connecting plate 3 and the frame assembly plate 402 to form a coaxial positioning fit, improving the geometric accuracy and anti-offset capability of the connection part, and effectively avoiding the structural loosening and rigidity reduction problems caused by assembly gaps or force eccentricity in traditional direct bolt connections.

[0050] like Figure 5 As shown, one end of the return spring 411 is fixedly connected to the inside of the mounting cylinder 408, and the other end of the return spring 411 is fixedly connected to the outside of the limiting ring 409. When the insert 410 is dislodged from the limiting plate 412 by external force to realize the folding operation of the folding frame mechanism 4, the return spring 411 stores elastic potential energy due to being stretched. Once the external force is removed, the return spring 411 automatically applies a restoring force to the limiting ring 409 through the fixed connection of one end to the inner wall of the mounting cylinder 408 and the fixed connection of the other end to the outer wall of the limiting ring 409. This drives the limiting ring 409 to slide along the inner wall of the mounting cylinder 408 and causes the insert 410 to re-insert into the limiting plate 412, thereby realizing the automatic locking of the insert 410 and the limiting plate 412. This ensures that the folding frame mechanism 4 always maintains a stable connection state in the unfolded state and effectively prevents the insert 410 from accidentally dislodging due to vibration or external force interference.

[0051] Furthermore, the reset spring 411 is sleeved on the outside of the insert post 410, and a pull ring 413 is fixedly connected to the end of the insert post 410 away from the limiting plate 412. A return spring 411 is sleeved on the outside of the insertion post 410, so that the return spring 411 applies stable force along the axial direction of the insertion post 410, preventing it from tilting or becoming unstable during extension and retraction. A pull ring 413 is fixedly connected to the end of the insertion post 410 away from the limiting plate 412. The operator can directly apply axial tension through the pull ring 413 to precisely control the sliding of the insertion post 410 in the mounting cylinder 408, thereby overcoming the elastic force of the return spring 411 and realizing the reliable separation or insertion of the insertion post 410 and the limiting plate 412. When unfolding the folding frame mechanism 4, pulling the pull ring 413 causes the insertion post 410 to exit from the limiting plate 412. After the vertical plate 404 rotates to the vertical position and is accurately aligned, the pull ring 413 is released, and the return spring 411 pushes the limiting ring 409 to reset along the axial direction of the insertion post 410, so that the insertion post 410 automatically inserts into the limiting plate 412 to complete locking. This structure improves the controllability and stability of the insertion operation.

[0052] To better understand this scheme, further explanation is provided below: The modular rapid construction prefabricated steel foundation structure of the communication tower includes three columns 1. Multiple fixed connection mounting plates 2 are fixedly connected to the upper and lower ends of each column 1. Six connecting plates 3 are detachably connected between the upper and lower fixed connection mounting plates 2. The connecting plates 3 are used to connect the three columns 1. Three folding frame mechanisms 4 are arranged between the multiple fixed connection mounting plates 2. A stabilizing mechanism 5 is installed inside the folding frame mechanism 4 to stabilize the folding frame mechanism 4. Three triangular frame mechanisms 6 are arranged between the multiple fixed connection mounting plates 2. The columns 1, connecting plates 3, folding frame mechanisms 4, stabilizing mechanisms 5, and triangular frame mechanisms 6 constitute the prefabricated foundation structure of the communication tower.

[0053] The folding frame mechanism 4 includes four connecting mounting plates 401. The connecting mounting plates 401 can provide a mounting base and can be fixed to the fixed connecting mounting plate 2 by bolts. One end of the connecting mounting plate 401 is detachably connected to the outside of the fixed connecting mounting plate 2. Four frame assembly plates 402 are rotatably connected between the four connecting mounting plates 401. The frame assembly plates 402 are mounted on the connecting mounting plates 401 by bolts. When the bolts are not tightened, the frame assembly plates 402 can rotate on the connecting mounting plates 401. When the bolts are tightened, the frame assembly plates 402 can be fixed. A detachable stabilizer 403 is provided between the upper and lower connecting mounting plates 401. The stabilizer 403 can be installed between the two connecting mounting plates 401 to prevent the upper and lower connecting mounting plates 401 from shaking. Multiple vertical plates 404 are rotatably connected between the upper and lower frame assembly plates 402. The vertical plates 404 can be connected between the upper and lower frame assembly plates 402. They can rotate when the bolts are not tightened and fix the two frame assembly plates 402 when the bolts are tightened.

[0054] An inclined plate 405 is detachably connected between the upper and lower frame assembly plates 402. After the bolts at both ends of the inclined plate 405 are tightened, the two frame assembly plates 402 can be fixed to prevent the frame assembly plates 402 from shaking. An installation cylinder 408 is fixedly connected to the bottom of one of the upper frame assembly plates 402. The installation cylinder 408 provides an installation position. A limit ring 409 is slidably connected inside the installation cylinder 408. The limit ring 409 has a limiting function. A plug 410 is fixedly connected to the middle of the limit ring 409. A return spring 411 is provided inside the installation cylinder 408. The return spring 411 can push the limit ring 409 to reset, thereby driving the plug 410 to reset. One of the vertical plates 404 has a fixed limit plate 412 at its top. After the insertion post 410 is inserted into the interior of the limit plate 412, it can prevent the vertical plate 404 from rotating, thereby allowing the folding frame mechanism 4 to be pre-expanded and erected. The insertion post 410 is inserted into the interior of the limit plate 412. Multiple connecting inner tubes 406 are fixedly connected to the side of the six frame assembly plates 402 near the connecting plate 3. Connecting outer tubes 407 are fixedly connected to the side of the six connecting plates 3 near the frame assembly plate 402. The connecting inner tubes 406 are detachably connected to the interior of the connecting outer tubes 407. The connecting inner tubes 406 are installed on the frame assembly plate 402, while the connecting outer tubes 407 are installed on the connecting plate 3. When the connecting outer tubes 407 are inserted into the interior of the connecting inner tubes 406 and tightened with bolts, the stability of the installation can be improved.

[0055] One end of the return spring 411 is fixedly connected to the inside of the mounting cylinder 408, and the other end of the return spring 411 is fixedly connected to the outside of the limiting ring 409. The return spring 411 is sleeved on the outside of the insert post 410. A pull ring 413 is fixedly connected to the end of the insert post 410 away from the limiting plate 412. The pull ring 413 is convenient for the user to pull. When pre-assembling the folding frame mechanism 4, first push one side of the upper connecting mounting plate 401. During the pushing process, the vertical plate 404 rotates from an inclined state to a vertical state. At this time, the limiting plate 412 can rotate as the vertical plate 404 is raised. When the limiting plate 412 rotates to the insert post 41 When the position is 0, pull the ring 413 outward, which will cause the limiting ring 409 to move in the direction of the ring 413 and compress the return spring 411 using the limiting ring 409. At this time, continue to push the upper connecting mounting plate 401. When the hole on the limiting plate 412 moves to the insertion post 410, release the ring 413. At this time, under the action of the reaction force of the return spring 411, the limiting ring 409 will move in the direction of the limiting plate 412, which will then cause the insertion post 410 to move, so that the insertion post 410 can be inserted into the hole of the limiting plate 412. At this time, the unfolded state of the folding frame mechanism 4 can be temporarily maintained.

[0056] At this point, one end of the inclined plate 405 is fixed to the lower frame assembly plate 402 with bolts. The upper rotating part of the inclined plate 405 can be fixed by tightening. Then, the stabilizing mechanism 5 is unfolded and fixed. At this point, the unfolding of the folding frame mechanism 4 can be completed. When folding the folding frame mechanism 4, first, the stabilizing mechanism 5 is retracted. Then, the pull ring 413 is pulled away from the limiting plate 412, thereby pulling the insert 410 out of the limiting plate 412. Then, the bolts at the bottom of the inclined plate 405 are unscrewed, and the upper side of the inclined plate 405 is loosened. The bolts on the vertical plate 404 are also loosened. At this point, the connecting mounting plate 401 can be pushed again, thereby rotating the vertical plate 404 from a vertical state to an inclined state. Then, the upper connecting mounting plate 401 and the frame assembly plate 402 can be brought into contact with the lower connecting mounting plate 401 and the frame assembly plate 402, thereby completing the folding of the folding frame mechanism 4.

[0057] The stabilizing mechanism 5 includes multiple mounting parts 501, which provide mounting positions. Each of the four corners of the mounting part 501 is provided with a support rod 502, which provides support. The support rod 502 has a through groove 514 inside. Each of the four corners of the mounting part 501 is fixedly connected with a fixing pin 513, which is located inside the through groove 514. The end of the support rod 502 away from the mounting part 501 is rotatably connected to a sliding sleeve 503. The fixing pin 513 can slide inside the through groove 514, thereby preventing motion interference between the support rod 502 and the fixing pin 513 when the sliding sleeve 503 slides towards the middle.

[0058] The outer wall of the sliding sleeve 503 has a slot 504. A movable column 505 is slidably connected to the middle of the mounting part 501. A tension spring 506 is installed inside the movable column 505. A fixing ring 507 is fixedly connected to the outside of the movable column 505. Four fixing plates 508 are fixedly connected to the outside of the fixing ring 507. A plug rod 509 is fixedly connected to the side of the fixing plate 508 near the mounting part 501. The movable column 505 can slide in the middle of the mounting part 501, and due to the tension of the tension spring 506, it can slide from... The movable column 505 can be prevented from sliding out of the mounting part 501, and the fixing ring 507 can be installed. When the fixing ring 507 is pulled, the movable column 505 can stretch the tension spring 506. Then, when the fixing ring 507 is released, the tension spring 506 pulls the movable column 505 back and resets the fixing ring 507. Then, the insertion rod 509 can be inserted into the support rod 502, thereby preventing the support rod 502 from rotating. At this time, the support rod 502 can achieve its supporting function.

[0059] A support column 510 is provided between the interior of the upper and lower sliding sleeves 503. Both ends of the support column 510 are fixedly connected to the locking blocks 511. When the locking groove 504 slides into the outside of the locking block 511, it can prevent the sliding sleeve 503 from rotating on the support column 510, thereby preventing the stabilizing mechanism 5 from rotating and tilting. It can further support the folding frame mechanism 4 and prevent the folding frame mechanism 4 from rotating and folding. The locking groove 504 and the locking block 511 are engaged. Both ends of the support column 510 are detachably connected between the two frame assembly plates 402. The insertion rod 509 is inserted into the interior of the support rod 502. The outside of the fixing ring 507 is fixedly connected to the handle 512. The handle 512 is pulled by the user. The insertion rod 509 is slidably connected to the interior of the mounting part 501. One end of the tension spring 506 is fixedly connected to the interior of the mounting part 501, and the other end of the tension spring 506 is fixedly connected to the interior of the movable column 505.

[0060] When the stabilizing mechanism 5 is retracted, the handle 512 is pulled away from the mounting part 501, which moves the fixing ring 507, and then moves the movable column 505 away from the mounting part 501, thus stretching the tension spring 506. At this time, the fixing plate 508 also moves away from the mounting part 501, which in turn moves the insert rod 509 away from the inside of the support rod 502. The support rod 502 can then be rotated, which moves the sliding sleeve 503 along the outside of the support column 510 towards the center. At the same time, due to the through groove 514, the support rod 502 can slide downwards. At this time, the slot 504 on the sliding sleeve 503 can move away from the outside of the locking block 511. When the folding frame mechanism 4 is folded, the stabilizing mechanism 5 is not... The limiting of the locking block 511 and the locking slot 504 allows the folding frame mechanism 4 to rotate and lie down when folded. When the stabilizing mechanism 5 is unfolded, the sliding sleeve 503 moves along the support column 510 to both ends and unfolds, which in turn drives the support rod 502 to unfold to both sides. When the hole on the support rod 502 moves to the insertion rod 509, the movable column 505 is pulled back to its original position under the tension of the tension spring 506, which in turn drives the fixing ring 507 to its original position. This then drives the fixing plate 508 and the insertion rod 509 to move towards the mounting part 501, so that the insertion rod 509 can be re-inserted into the hole of the support rod 502. At the same time, the locking slot 504 on the sliding sleeve 503 can be re-inserted into the outside of the locking block 511, thus completing the unfolding of the stabilizing mechanism 5.

[0061] The triangular frame mechanism 6 includes four I-beams 601, four rotating steel plates 603, and four rotating outer edge steels 604. One end of each of the four I-beams 601 is detachably connected to the outside of two fixed connection mounting plates 2. The I-beams 601 serve as the foundation support columns. Two connecting steel plates 602 are detachably connected between the four I-beams 601, allowing two I-beams 601 to be joined together. Both ends of the rotating steel plates 603 and the rotating outer edge steels 604 are fixedly connected to end cylinders 605. Both 03 and the rotating outer edge steel 604 can install the end cylinder 605 at both ends. The end cylinder 605 is provided with a supporting spring 606. Two hexagonal limiting blocks 607 are slidably connected inside the end cylinder 605. A threaded pin 608 is fixedly connected to the end of the hexagonal limiting block 607 away from the supporting spring 606. The hexagonal limiting block 607 has a limiting function. When the nut on the threaded pin 608 is turned, it can prevent the threaded pin 608 from rotating and prevent the threaded pin 608 from moving out of the end cylinder 605.

[0062] The supporting spring 606 can push the threaded pin 608 out of the end cylinder 605 without any force pressing it down, allowing the threaded pin 608 to pass through the holes in the I-beam 601 and the connecting mounting plate 401. After the threaded pin 608 passes through the holes in the I-beam 601 and the connecting mounting plate 401, the nut on the threaded pin 608 is tightened, thereby allowing the rotating steel plate 603 and the rotating outer edge steel 604 to be mounted on the three folding frame mechanisms 4, and subsequently, the triangular frame can be... Mechanism 6 is connected to folding frame mechanism 4, and can connect triangular frame mechanism 6 and column 1 using I-beam 601, thereby completing the installation of the communication tower foundation structure. Before tightening the nut on threaded pin 608, the pre-installation of triangular frame mechanism 6 can be completed, which facilitates the tightening of the nut. After installing rotating steel plate 603 and rotating outer edge steel 604 on I-beam 601, rotating steel plate 603 and rotating outer edge steel 604 can be rotated without tightening the nut on threaded pin 608.

[0063] When the rotating steel plate 603 and the rotating outer edge steel 604 are rotated and folded, they can save placement and transportation space, thus facilitating placement and transportation. One end of the rotating steel plate 603 and the rotating outer edge steel 604 are rotatably connected to the inside of the I-beam 601 by threaded pins 608. The other end of the rotating steel plate 603 and the rotating outer edge steel 604 are rotatably connected to the inside of the connecting mounting plate 401 by threaded pins 608. The two ends of the supporting spring 606 are respectively fixedly connected to one end of the two hexagonal limit blocks 607. A support frame 1 609 is fixedly connected between the upper and lower rotating outer edge steels 604. A support frame 2 610 is fixedly connected between the upper and lower rotating steel plates 603. A base plate 7 is fixedly connected between the bottom of the two lower rotating outer edge steels 604 and the bottom of the three frame assembly plates 402.

[0064] When the folding frame mechanism 4 is installed on the column 1 via the fixed connection mounting plate 2, unscrew the bolt on the threaded pin 608 and press the threaded pin 608 downwards, thereby driving the hexagonal limit block 607 to move downwards. This allows the hexagonal limit block 607 to compress the support spring 606. At this point, the threaded pin 608 moves into the interior of the support spring 606. Then, insert the end cylinder 605 into the inside of the I-beam 601, and then re-tighten the nut onto the outside of the threaded pin 608. The method for pre-installing the outer edge steel 604 inside the I-beam 601 is the same as the method for installing the rotating steel plate 603. Finally, install the I-beam 601 onto the fixed connection mounting plate 2 with bolts. On mounting plate 2, rotate steel plate 603 to open, allowing end cylinder 605 on the side away from I-beam 601 to be inserted into the inner side of connecting mounting plate 401. Loosen threaded pin 608. At this time, under the reaction force of support spring 606, it moves upward and allows threaded pin 608 to move into the hole of connecting mounting plate 401. The pre-installation method of rotating outer edge steel 604 is the same as the pre-installation method of rotating steel plate 603. At this time, the pre-installation of triangular frame mechanism 6 is completed. Then tighten the nut on threaded pin 608 to fix rotating steel plate 603 and rotating outer edge steel 604, thereby completing the construction of the basic structure of communication tower.

[0065] The present invention also provides an installation method for the above-mentioned modular rapid construction prefabricated steel foundation structure of communication towers, comprising the following steps:

[0066] Step 1: Unfold the folding frame mechanism 4 and fix the bolts on the folding frame mechanism 4. At the same time, unfold the stabilizing mechanism 5 and lock the stabilizing mechanism 5.

[0067] Step 2: Use the fixed connection mounting plate 2 to install the unfolded folding frame mechanism 4 in Step 1 on the outside of the column 1, and then pre-install the three triangular frame mechanisms 6 between the three folding frame mechanisms 4.

[0068] Step 3: Fix the triangular frame mechanism 6 pre-installed on the folding frame mechanism 4 in Step 2, and then use the fixed connection mounting plate 2 to install and fix the triangular frame mechanism 6 to the column 1.

[0069] By first unfolding the folding frame mechanism 4 and fixing the bolts, and simultaneously unfolding and locking the stabilizing mechanism 5, the structural stability of the folding frame mechanism 4 is ensured during the pre-assembly stage. Then, the unfolded folding frame mechanism 4 is installed to the outside of the column using a fixed connection mounting plate, and a triangular frame mechanism 6 is pre-installed between the three folding frame mechanisms 4 to achieve modular pre-assembly of the basic structure. Finally, the triangular frame mechanism 6 is finally fastened to the column using the fixed connection mounting plate to complete the assembly of the overall basic structure. This method reduces the frequency of high-strength bolt operations on site through pre-installation and step-by-step locking mechanisms, avoids the space occupation and operational difficulties caused by unfolding the overall structure at once, and improves the smoothness and efficiency of on-site assembly. At the same time, relying on the coordinated cooperation of structures such as the connecting inner tube and connecting outer tube, the insert column and the limiting plate, and the supporting spring and the hexagonal limiting block, the positioning accuracy and connection reliability of each component are ensured during the pre-assembly and final assembly stages.

[0070] The working principle and specific operation instructions of the above scheme are as follows:

[0071] When pre-assembling the folding frame mechanism 4, first push one side of the upper connecting mounting plate 401. During the pushing process, the vertical plate 404 rotates from an inclined state to a vertical state. At this time, the limiting plate 412 can rotate as the vertical plate 404 is raised. When the limiting plate 412 rotates to the insertion post 410, pull the pull ring 413 outward, which can drive the limiting ring 409 to move in the direction of the pull ring 413. The limiting ring 409 compresses the return spring 411. Then continue to push the upper connecting mounting plate 401. After the hole on the limiting plate 412 moves to the insertion post 410, release the pull ring 413. At this time, under the reaction force of the return spring 411, the limiting ring 409 moves in the direction of the limiting plate 412, which in turn drives the insertion post 410 to move, so that the insertion post 410 can be inserted into the hole of the limiting plate 412. At this time, the unfolded state of the folding frame mechanism 4 can be temporarily maintained. Then, fix one end of the inclined plate 405 to the lower frame assembly plate 402 with bolts. The upper rotating part of the inclined plate 405 can be fixed by tightening. Then unfold and fix the stabilizing mechanism 5. At this time, the unfolding of the folding frame mechanism 4 can be completed. When folding the folding frame mechanism 4, first retract the stabilizing mechanism 5, then pull the pull ring 413 away from the limiting plate 412, thereby pulling the insert 410 out of the limiting plate 412. Then unscrew the bolts at the bottom of the inclined plate 405, and at the same time loosen the upper side of the inclined plate 405 and loosen the bolts on the vertical plate 404. At this time, the connecting mounting plate 401 can be pushed again, thereby rotating the vertical plate 404 from the vertical state to the inclined state. Then, the upper connecting mounting plate 401, the frame assembly plate 402 can be brought into contact with the next connecting mounting plate 401 and the frame assembly plate 402, thereby completing the folding of the folding frame mechanism 4.

[0072] When the stabilizing mechanism 5 is retracted, the handle 512 is pulled away from the mounting part 501, which moves the fixing ring 507, and then moves the movable column 505 away from the mounting part 501, thus stretching the tension spring 506. At this time, the fixing plate 508 also moves away from the mounting part 501, which in turn moves the insert rod 509 away from the inside of the support rod 502. The support rod 502 can then be rotated, which moves the sliding sleeve 503 along the outside of the support column 510 towards the center. At the same time, due to the through groove 514, the support rod 502 can slide downwards. At this time, the slot 504 on the sliding sleeve 503 can move away from the outside of the locking block 511. When the folding frame mechanism 4 is folded, the stabilizing mechanism 5 is not... The limiting of the locking block 511 and the locking slot 504 allows the folding frame mechanism 4 to rotate and lie down when it is folded. When the stabilizing mechanism 5 is unfolded, the sliding sleeve 503 moves along the support column 510 to both ends and unfolds, which in turn drives the support rod 502 to unfold to both sides. When the hole on the support rod 502 moves to the insertion rod 509, the movable column 505 is pulled back to its original position under the tension of the tension spring 506, which in turn drives the fixing ring 507 to its original position. This then drives the fixing plate 508 and the insertion rod 509 to move towards the mounting part 501, so that the insertion rod 509 can be re-inserted into the hole of the support rod 502. At the same time, the locking slot 504 on the sliding sleeve 503 can be re-inserted into the outside of the locking block 511, thus completing the unfolding of the stabilizing mechanism 5.

[0073] When the folding frame mechanism 4 is installed on the column 1 via the fixed connection mounting plate 2, unscrew the bolt on the threaded pin 608 and press the threaded pin 608 downwards, thereby driving the hexagonal limit block 607 to move downwards. This allows the hexagonal limit block 607 to compress the support spring 606. At this point, the threaded pin 608 moves into the interior of the support spring 606. Then, insert the end cylinder 605 into the inside of the I-beam 601, and then re-tighten the nut onto the outside of the threaded pin 608. The method for pre-installing the outer edge steel 604 inside the I-beam 601 is the same as the method for installing the rotating steel plate 603. Finally, install the I-beam 601 onto the fixed connection mounting plate 2 with bolts. On mounting plate 2, rotate steel plate 603 to open, allowing end cylinder 605 on the side away from I-beam 601 to be inserted into the inner side of connecting mounting plate 401. Loosen threaded pin 608. At this time, under the reaction force of support spring 606, it moves upward and allows threaded pin 608 to move into the hole of connecting mounting plate 401. The pre-installation method of rotating outer edge steel 604 is the same as the pre-installation method of rotating steel plate 603. At this time, the pre-installation of triangular frame mechanism 6 is completed. Then tighten the nut on threaded pin 608 to fix rotating steel plate 603 and rotating outer edge steel 604, thereby completing the construction of the basic structure of communication tower.
