Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, and in particular to an electric retractable ring-shaped steel formwork adjustment device. Background Technology

[0002] In the construction and manufacturing of various circumferential structures such as silos and oil depots, the precise assembly of circumferential formwork is a crucial step. Circumferential formwork is typically assembled from multiple arc-shaped formwork units along the circumference. However, in practice, due to factors such as potential manufacturing errors in the formwork units themselves, deformation after long-term use, difficulties in benchmark positioning during on-site installation, and the inability to control cumulative errors, problems such as misalignment, gaps, or angular deviations often occur at the joints of adjacent formwork units. This results in incomplete formwork assembly, uneven joints, and consequently, poor concrete pouring and forming results.

[0003] For example, a Chinese patent discloses an adjustable device for the circumferential template of a secondary lining template trolley (application number: CN202420732962.5). This device includes two parallel travel tracks, each with a sliding seat above it. Several support columns are arranged between the inner sides of the sliding seats. The sliding seats are driven by an inner drive motor. A secondary lining trolley frame is located between the sliding seats. Several plates are connected to the outer perimeter of the lining trolley frame via several hydraulic cylinder piston rods and a top frame. These plates are combined to form a circumferential template. Symmetrical adjustable devices are provided on the outer sides of each sliding seat. These adjustable devices can adjust the sides and front-to-back junctions of the assembled circumferential template. Furthermore, they can improve the installation stability of the lowest plates on both sides of the circumferential template, thus improving the overall effect of subsequent concrete pouring.

The horizontal adjustment mechanism 1 is installed on the track beam 3, the track beam 3 is installed on the frame structure 4, and the vertical adjustment mechanism 2 is connected to the horizontal adjustment mechanism 1.

[0023] Furthermore, the track beam 3 is an I-beam, and a first elongated hole 31 is provided in the middle of the track beam 3. The upper part of the track beam 3 is connected to the frame structure 4 through a clamp 32.

[0024] The following benefits are derived from the adoption of further technical solutions: the track beam 3 is made of I-beams, which have high strength and load-bearing capacity, and can stably support components such as the lateral adjustment mechanism 1; the first elongated hole 31 facilitates the installation and movement adjustment of the lateral adjustment mechanism 1; and it is connected to the frame structure 4 through the clamp 32, which is a simple and reliable connection method and facilitates the installation and disassembly of the track beam 3.

[0025] Furthermore, the lateral adjustment mechanism 1 includes a movable channel steel component 101 and an electric push rod 102. The movable channel steel component 101 is slidably mounted on the track beam 3, and the electric push rod 102 is fixedly mounted on the track beam 3. The output end of the electric push rod 102 is hinged to one end of the movable channel steel component 101, and the other end of the movable channel steel component 101 is connected to an ear plate 103.

[0029] Furthermore, the movable channel steel component 101 includes a first channel steel 106 and a second channel steel 107. A second elongated hole 108 is provided in the middle section of both the first channel steel 106 and the second channel steel 107. A plurality of screw holes 109 are provided at the other end of both the first channel steel 106 and the second channel steel 107.

[0030] The advantages of adopting further technical solutions are as follows: the second elongated hole 108 in the middle section of the first channel steel 106 and the second channel steel 107 of the movable channel steel component 101 facilitates connection with the track beam 3 and enables relative sliding, while the several screw holes 109 at the other end facilitate the fixed connection between the two, making the structural design of the movable channel steel component 101 reasonable and easy to install, adjust and fix.

[0031] Furthermore, the first channel steel 106 and the second channel steel 107 are movably connected to the track beam 3 by a number of high-strength screws and pads 120 through the first elongated hole 31 and the second elongated hole 108.

[0032] The benefits of adopting a further technical solution are as follows: This connection method not only ensures the stability of the connection between the two and the track beam 3, but also does not affect the sliding of the movable channel steel component 101 on the track beam 3. The high-strength screw and pad 120 enhance the strength and reliability of the connection.

[0033] Furthermore, one end of the first channel steel 106 and the second channel steel 107 are both hinged to the output end of the electric push rod 102, and the other ends of the first channel steel 106 and the second channel steel 107 are fixedly connected by high-strength bolts through screw holes 109.

[0034] The following benefits are provided by adopting a further technical solution: one end of the first channel steel 106 and the second channel steel 107 is hinged to the output end of the electric push rod 102, which facilitates the electric push rod 102 to drive them to move; the other end is fixedly connected by a high-strength bolt through the screw hole 109, so that the two form a whole, which enhances the structural strength and stability of the moving channel steel component 101 and ensures that it moves synchronously and stably.

[0035] Furthermore, the vertical adjustment mechanism 2 includes an electric hoist 21 and a wire rope 22. The upper part of the electric hoist 21 is connected to the ear hole 104 of the ear plate 103. One end of the wire rope 22 is connected to the electric hoist 21, and the other end of the wire rope 22 is connected to the steel mold 5.

[0036] The benefits of adopting a further technical solution are as follows: The electric hoist 21 of the vertical adjustment mechanism 2 is connected to the ear hole 104 of the ear plate 103, which is convenient and reliable. The electric hoist 21 is connected to the steel mold 5 through the steel wire rope 22, which can realize the vertical electric lifting and lowering adjustment of the steel mold 5.

[0038] The adoption of further technical solutions offers the following benefits: The electric push rod 102 and electric hoist 21 are connected to the controller 6, which in turn is connected to the control box 7, enabling centralized control of horizontal and vertical adjustments. Operators can conveniently control the device's operation through the control box 7, improving operational convenience and safety. This also facilitates automated control and enhances construction efficiency. The mobile device terminal 11 and monitoring center 12 can remotely control the hoisting operation via the cloud server 9 and network module 8, while the camera 13 provides on-site video support.

[0039] Compared with the prior art, the present invention has the following advantages: The lateral adjustment mechanism 1 drives the sliding of the moving channel steel component 101 through the electric push rod 102, which can realize the precise and efficient lateral adjustment of the steel mold 5, reducing manual operation errors and strength; The vertical adjustment mechanism 2, with the help of the electric hoist 21 and the wire rope 22, can flexibly adjust the vertical position of the steel mold 5 to meet the construction needs of different heights, and is easy to operate; The track beam 3 adopts I-beams and has a first elongated hole 31, which not only ensures the structural strength, but also provides a stable track for the movement of the lateral adjustment mechanism 1, and is connected to the frame structure 4 through the clamp 32; This enhances the stability and ease of installation of the overall device, while the frame structure 4 provides solid support for the entire device, ensuring the overall stability of the device during the adjustment process; The controller 6 and the control box 7 allow operators to conveniently control the operation of the device.

[0040] Working principle: First, the controller 6 is operated via the control box 7 to activate the electric push rod 102 in the lateral adjustment mechanism 1. The output end of the electric push rod 102 pushes the movable channel steel component 101 to slide on the track beam 3. The movable channel steel component 101 moves along the first elongated hole 31 and its own second elongated hole 108 of the track beam 3 through the first channel steel 106 and the second channel steel 107, thereby adjusting the lateral position of the steel mold 5. Subsequently, the electric hoist 21 in the vertical adjustment mechanism 2 is activated via the controller 6. The electric hoist 21 drives the steel mold 5 to rise or fall via the steel wire rope 22, completing the vertical position adjustment of the steel mold 5. Throughout the process, the track beam 3 is fixed to the frame structure 4 by the clamp 32, providing stable support for the operation of each mechanism.

[0041] Example 1: Application of steel formwork adjustment for subway station side walls This embodiment focuses on the construction of the side wall of the second basement level of a standard subway station. The side wall is designed to be 6m high and 300mm thick, and adopts segmented steel formwork construction (each steel formwork piece measures 6m × 3m × 0.3m and weighs approximately 8t). The core construction requirements are: to achieve precise segmented splicing of the steel formwork along the length of the side wall (lateral direction) (joint error ≤ 5mm), and to seamlessly connect vertically with the top and bottom slab formwork (vertical positioning error ≤ 3mm). At the same time, it must adapt to the limited underground construction space and reduce the intensity of manual labor.

[0042] A rectangular frame is welded from Q355 H-beams (HN500×200×10×16) with dimensions of 12m (lateral) × 5m (longitudinal) × 8m (height). It is fixed to the pre-embedded steel plate on the station floor slab (20mm thick) with M30 expansion bolts. Four sets of anti-overturning supports (using ∠100×8 angle steel) are set at the bottom of the frame to ensure the overall stability of the device during underground construction and avoid lateral displacement or overturning.

[0043] 40a I-beams (section height 400mm, web thickness 10.5mm, theoretical weight 67.59kg / m) are selected, with a single beam length of 12m. A first elongated hole 31, 20mm wide and 11.8m long, is opened in the middle (with 100mm reserved at each end as limiting sections). Custom-made U-shaped clamps 32 (material Q355, clamp opening width 400mm, equipped with M24 high-strength bolts) are used to connect to the transverse beams of the frame structure 4. One set of clamps is set every 2m, for a total of 6 sets, to ensure that the track beam's load-bearing capacity meets the sliding requirements of the 8t steel mold.

[0044] The movable channel steel component 101 is made of 25a channel steel (section height 250mm, web thickness 7mm, theoretical weight 38.10kg / m). The first channel steel 106 and the second channel steel 107 are both 5m long. A second elongated hole 108 with a width of 22mm and a length of 4.8m is opened in the middle section (matching the first elongated hole 31 to ensure the sliding stroke).

[0045] Electric actuator 102: A DC electric actuator (model DTZ1000-200, rated voltage 24V) with a thrust of 100kN and a stroke of 2m is selected. It is fixed on an H-shaped steel bracket at one end of the track beam 3. The output end is hinged to one end of the first channel steel 106 and the second channel steel 107 through a Φ30 pin to ensure uniform transmission of thrust.

[0046] Ear plate and reinforcing structure: Ear plate 103 is made of 20mm thick Q355 steel plate (size 200mm×150mm), ear hole 104 diameter 50mm (for electric hoist pin shaft); two 16mm thick reinforcing ribs 105 (size 150mm×100mm, bevel angle 45°) are welded between ear plate 103 and moving channel steel component 101 to enhance the shear strength of ear plate and prevent deformation under stress.

[0047] Connection method: The first channel steel 106 and the second channel steel 107 are connected to the upper and lower flanges of the track beam 3 by M24 high-strength screws (8.8 grade, preload torque 500 N·m) and pads 120 (200mm×200mm×10mm, material Q235). They pass through the first elongated hole 31 and the second elongated hole 108 and are clamped. One set of screws is set every 1m, for a total of 4 sets, which ensures both sliding flexibility and avoids shaking.

[0048] (4) Vertical adjustment mechanism 2 Electric hoist 21: Select a wire rope electric hoist with a rated lifting capacity of 10t and a lifting height of 12m (model CD10-12D, lifting speed 8m / min, lowering speed 10m / min). The upper part is connected to the ear plate 103 ear hole 104 through a Φ48 pin shaft. Cotter pins are provided at both ends of the pin shaft to prevent it from falling off.

[0049] Steel wire rope 22: Select 6×37+FC steel wire rope with a diameter of 20mm (breaking tensile strength 235kN, safety factor ≥6), length 15m, and connect both ends to the electric hoist hook and the two lifting points on the top of the steel formwork 5 (lifting point spacing 4m, symmetrical arrangement) through wedge joints to ensure that the steel formwork is subjected to balanced vertical force and avoids tilting.

[0050] (5) Control and monitoring section Control Unit: Controller 6 is a Siemens S7-1200 PLC (with analog module, supporting current signal acquisition). Control box 7 is set on the station ground operating platform (with rainproof and dustproof cover, built-in 10-inch touch screen), which can display the electric push rod stroke and electric hoist lifting height in real time.

[0051] Remote monitoring: Network module 8 uses a 4G industrial router (model USR-G806, supporting VPN encrypted transmission), cloud server 9 uses Alibaba Cloud ECS (2 cores 4G configuration, storing 3 months of running data); mobile device terminal 11 installs a customized APP (supports Android / iOS, can be remotely started / stopped and adjusted, latency ≤1s); frame structure 4 has 1 4K high-definition camera 13 installed at each of the four corners (night vision distance 30m, with AI motion detection) to transmit the relative position of steel formwork, steel bars, and embedded sleeves in real time to avoid collisions.

[0052] Efficiency Improvement: Traditional manual pushing of steel molds requires 4 people to cooperate and a single horizontal adjustment takes about 30 minutes. This device's electric adjustment only takes 5 minutes, increasing efficiency by 6 times; vertical adjustment is reduced from 20 minutes with the traditional winch to 8 minutes, increasing efficiency by 2.5 times.

[0053] Precision assurance: lateral adjustment accuracy ±2mm (meets the design requirement of joint error ≤5mm), vertical positioning error ±1mm (solves the problem of grout leakage caused by the 10mm error in traditional hoisting), and the steel formwork splicing quality pass rate is increased from 85% to 100%.

[0054] Safety optimization: Operators no longer need to manually adjust the device in the narrow space of the side wall. They can operate it remotely through the ground control box or mobile APP. Combined with real-time camera monitoring, the risk of falling from heights and being struck by objects is reduced by 90%.

[0055] Example 2: Application of steel formwork adjustment for viaduct cap beams This embodiment focuses on the construction of the cap beam for an elevated urban expressway. The cap beam has a span of 15m, a height of 3m, and a thickness of 400mm. Each steel formwork piece measures 15m × 3m × 0.4m and weighs approximately 12t.

[0056] The frame adopts a lattice steel frame (main material is ∠140×10 angle steel, lacing strip is ∠80×6 angle steel, node plate thickness is 16mm), with dimensions of 18m (lateral) × 6m (longitudinal) × 10m (height). It is fixed to the pier by two sets of arc-shaped clamps (lined with 30mm thick neoprene rubber pads to prevent damage to the pier concrete). The clamp bolts are M36 high-strength bolts (grade 10.9, preload torque 1200N・m). Four sets of windproof cables (16mm diameter steel wire rope) are installed at the top of the frame to cope with outdoor winds below level 6.

[0057] 56a I-beams (section height 560mm, web thickness 13mm, theoretical weight 106.31kg / m) are selected, with a single length of 18m.

Double bolt clamps 32 (material Q355, equipped with M30 bolts, each clamp set contains 2 bolts) are used to connect to the longitudinal main beam of the frame structure 4. One set of clamps is installed every 1.5m, for a total of 11 sets, to ensure that the track beam does not deflect during the sliding of the 12t steel mold (maximum deflection ≤ L / 500, where L is the span of the track beam).

[0060] Ear plate and reinforcing structure: Ear plate 103 is made of 25mm thick Q355 steel plate (size 250mm×200mm), ear hole 104 diameter 60mm; three 20mm thick reinforcing ribs 105 (size 200mm×150mm) are welded between ear plate 103 and movable channel steel component 101 to enhance pull-out strength (can withstand 16t tensile force).

[0061] Connection method: The first channel steel 106 and the second channel steel 107 are connected to the track beam 3 by M30 high-strength screws (grade 10.9, preload torque 800 N·m) and pads 120 (250 mm × 250 mm × 12 mm). The screws pass through the first elongated hole 31 and the second elongated hole 108 and are clamped on the track beam 3. One set of screws is set every 0.8 m, for a total of 6 sets, to ensure smooth sliding at high altitudes.

[0063] Wire rope 22: Select 6×37+IWR wire rope with a diameter of 24mm (breaking strength 320kN, safety factor ≥8). Each electric hoist is equipped with 2 hoisting ropes (20m in length). They are connected to both ends of the balance beam through shackles. The balance beam is connected to the steel formwork through 4 lifting points (spaced 3m apart) to ensure that the horizontal error of the steel formwork is ≤1mm / m when it is raised and lowered vertically.

[0064] Control unit: Controller 6 is a Siemens S7-1500 PLC (with Profinet communication module, supporting synchronous control of multiple devices), and control box 7 is set on the construction platform under the bridge (with rainproof and lightning protection modules), with built-in emergency stop button (response time ≤0.5s).

[0065] Remote monitoring: Network module 8 uses a 5G industrial router (model USR-G810-5G, supporting edge computing), and cloud server 9 is a self-built edge server for the project (deployed at the project site, latency ≤50ms); mobile device terminal 11 supports dual-end control of tablets and mobile phones, and can view real-time data of electric push rod thrust and electric hoist lifting weight; one spherical camera 13 (4K resolution, horizontal rotation 360°, vertical rotation -90°~90°) is installed on each side of the four piers of the frame structure, and is connected to the city's smart construction site platform to realize remote supervision.

[0066] Symmetrical adjustment precision: Two electric push rods are adjusted synchronously, and the distance between the steel formwork and the pier can be controlled within 500mm±1mm (far exceeding the design requirement of ±5mm), avoiding the unilateral deviation caused by traditional manual pulling (the traditional error is about 8mm), and increasing the pass rate of the protective layer thickness of the cap beam reinforcement from 90% to 98%.

[0067] Vertical positioning efficiency: Two electric hoists lift and lower synchronously, and the gap between the bottom of the steel formwork and the pier bracket is controlled at 10mm±0.5mm. No need for a large number of iron plates to be inserted for leveling afterward, reducing the leveling workload by 70%. After the cap beam is poured, the flatness error of the top surface is ≤3mm / m.

[0068] Outdoor adaptability: The device is designed with windproof cables, rainproof control boxes, and lightning protection modules, enabling normal construction in outdoor environments with winds up to level 6 and moderate rain. Compared with traditional equipment (which requires work stoppage in windy and rainy weather), the effective construction time is increased by 20%. At the same time, remote control reduces the number of personnel working at heights (from 5 to 2), reducing the risk of high-altitude safety by 80%.

Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
