[0001] This invention relates to the field of concrete formwork support technology, and in particular to a self-supporting mechanism and construction method for multi-directional inclined tower limb concrete formwork. Background Technology

Traditional support systems typically employ steel or timber structures, which are not only costly but also pose numerous safety hazards during construction. Furthermore, for multi-directional inclined towers, traditional support systems often fail to provide effective support and stability. Therefore, the need for a self-supporting mechanism and construction method for concrete formwork of multi-directional inclined towers to improve construction efficiency and quality while reducing costs and risks is a crucial requirement in the current civil engineering field.

[0010] Preferably, both ends of the plurality of pull rods are threaded with tapered helical tubes, and the two tapered helical tubes threaded to both ends of each pull rod are respectively located inside the two side templates. The other ends of the plurality of tapered helical tubes are threaded with adjusting screws.

A locking nut is provided on one side of the pad, and the inner wall of the locking nut is threaded to the surface of the adjusting screw. The plurality of adjusting screws are respectively composed of a plurality of left-hand adjusting screws and a plurality of right-hand adjusting screws.

[0011] Preferably, the synchronous drive adjustment device includes a limiting and fixing clamping block, and multiple limiting and fixing clamping blocks are provided, with each limiting and fixing clamping block located on one side of the multiple pads. A clamping groove is opened at the bottom of the limiting and fixing clamping block, and the inner wall of the clamping groove is slidably inserted into the surface of the side template. A locking screw is threadedly connected to one inner wall of the clamping groove, and the pressing end of the locking screw is pressed against the surface of the side template.

[0012] Preferably, a limiting plate is fixedly installed on the top of the limiting and fixing clamping block, a slide rail is fixedly installed on the surface of the limiting plate, a sliding plate is slidably inserted into the surface of the slide rail, and a clamping plate is rotatably connected to one end of the sliding plate through a turntable bearing.

[0013] Preferably, a slot is formed on one side surface of the clamping plate, the inner wall of the slot is hexagonal, a through hole is formed on the inner wall of the slot, the inner wall of the through hole is movably sleeved with the arc surface of the adjusting screw, an adjusting hole is formed on the inner side wall of the slot, a pressing rod is slidably inserted into the inner wall of the adjusting hole, and a driven sprocket is fixedly installed on the arc surface of the other end of the clamping plate.

[0014] Preferably, an extrusion plate is fixedly installed at one end of every three extrusion rods, and a spring is fixedly installed on one side surface of the extrusion plate. One end of the spring contacts the inner wall of the slot, and the inner ring of the spring is movably sleeved with the arc surface of the extrusion rod. The surface of every three extrusion plates is pressed against the outer surface of one locking nut.

[0015] Preferably, the surfaces of the two limiting plates installed on the top and bottom left side of the side template are each fixedly mounted with a connecting rod, and the opposite ends of the two connecting rods are each fixedly mounted with a guide plate. The surface of the guide plate is fixedly mounted with a guide rail, and both ends of the guide plate are rotatably connected with threaded rods through bearings. One end of the threaded rod passes through and extends to the outside of the guide plate, and an auxiliary motor is fixedly mounted on the surface of the guide plate. The output shaft of the auxiliary motor is fixedly mounted to one end of the threaded rod through a coupling.

[0016] Both guide rails have auxiliary slide plates slidably inserted into their surfaces. The surfaces of the auxiliary slide plates are threadedly connected to the surfaces of the threaded rods. A synchronous rotary motor is fixedly installed at one end of the auxiliary slide plate. A sprocket shaft is fixedly installed on the output shaft of the synchronous rotary motor through a coupling. A drive sprocket is fixedly installed at one end of the sprocket shaft. Chains are drivingly connected to the surfaces of the multiple driven sprockets and the drive sprocket.

[0017] The present invention proposes a construction method for a self-supporting mechanism for concrete formwork of a multi-directional inclined tower. Step 1: Complete the binding of the stiffening frame and welding at both ends in sequence. Install the formwork sequentially from the top and fix it temporarily. When installing the side formwork, connect the tapered screw tube to the adjusting screw through the formwork self-supporting device. Then install the tie rod on the inner side of the threaded connection and weld it to the surface of the stiffening frame to fix the tie rod.

[0018] Step 2: After the tie rod is welded and fixed, the clamping slot of the synchronous drive adjustment device is used to control multiple limit fixing clamping blocks to be installed on the surface of the side template. The locking screw is used to lock and fix them, so that the limit fixing clamping blocks are installed and locked. The clamping plate is controlled to engage with the surface of the locking nut, and the surfaces of the three extrusion plates are driven to be pressed against the surface of the locking nut under the reverse extrusion force of the spring.

[0019] Step 3: After the multiple clamps are engaged with the locking nuts threaded to one end of each adjusting screw, they are all stationary in the initial moving position of the slide rail. The chain is then used to control the drive sprocket and multiple driven connections to be connected in series and located on the same horizontal plane.

[0020] Step 4: Simultaneously drive the auxiliary motor and the synchronous rotary motor. The synchronous rotary motor drives the sprocket shaft to rotate, which in turn drives the drive sprocket to rotate. The drive sprocket then drives the chain drive, thereby synchronously controlling the rotation of multiple sprockets. This, in turn, synchronously drives the rotation of multiple clamping discs, controlling the synchronous rotation and locking of the internally engaged locking nuts. As the multiple locking nuts rotate and move synchronously, they drive the multiple clamping discs to move towards the limiting and fixing clamping block. This, in turn, cooperates with the rotation of the auxiliary motor. The rotation of the auxiliary motor drives the threaded rod to rotate, which in turn drives the auxiliary slide plate with the surface threaded connection to move synchronously with the multiple clamping discs.

[0021] Step 5: After multiple locking nuts move synchronously and lock, stop working and wait for concrete pouring. When disassembly is required after pouring, control the synchronous rotary motor and auxiliary motor to reverse the operation, which will drive the locking nuts to move in reverse for disassembly. After the locking nuts are disassembled, the limit fixing clamping block can be disassembled by loosening the locking screw. The side formwork can be disassembled by disassembling the adjusting screw.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. This device incorporates a self-supporting formwork during the concrete pouring of multi-directional inclined tower limbs. This self-supporting effect ensures the formwork is subjected to tension and compression during the concrete pouring process, guaranteeing structural safety and stability. The use of a rigid frame as the primary load-bearing structure for formwork support achieves structural uniformity, eliminates the need for lateral formwork support, reduces workload, and improves the efficiency of segmented tower limb construction. The adoption of weldable tie rods and tapered nuts ensures standardized tie rod holes, aesthetically pleasing sealing, and a high-quality concrete appearance.

[0024] 2. The synchronous drive adjustment device can simultaneously control the tightening operation of multiple locking nuts, avoiding the time wasted by adjusting and tightening each nut individually, thereby improving production efficiency. Under synchronous control, multiple locking nuts can maintain a consistent tightening force, preventing damage to the template installation or loosening due to inconsistent tightening force caused by different operators. The synchronous drive adjustment device can automatically complete the tightening operation of multiple locking nuts, reducing the labor intensity and fatigue of operators.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Reference Figures 1-9 A multi-directional inclined tower limb concrete formwork self-supporting mechanism includes concrete columns 1, a casting connection device 2 is provided between the opposite surfaces of every two concrete columns 1, a formwork self-supporting device 3 is provided on both sides of the casting connection device 2, and a synchronous drive adjustment device 4 is also provided on the surface of the formwork self-supporting device 3.

[0037] To achieve the connection of the two concrete columns 1 into a whole, a casting connection device 2 is installed, including a rigid frame 21. The two ends of the rigid frame 21 are welded and fixed to the steel reinforcement on the opposite surfaces of the two concrete columns 1. Through the welding and fixing of the rigid frame 21, the two concrete columns 1 can be effectively connected together to form a single structure. This enhances the stability and load-bearing capacity of the structure and improves the seismic performance of the building. A bottom formwork 22 is installed at the bottom of the rigid frame 21, and side formwork 23 is installed on both sides of the rigid frame 21. The two side formwork 23 are flared, with the top flared opening larger than the bottom flared opening. The side formwork 23 consists of an inner formwork and an outer formwork.

[0038] Specifically, the use of the pouring connection device 2 simplifies the construction process. The bottom of the rigid frame 21 is equipped with a bottom formwork 22 and side formwork 23, which effectively fix and support the frame, ensuring accurate positioning. Furthermore, the flared design of the side formwork 23 facilitates concrete pouring into the rigid frame 21, improving pouring efficiency; it also effectively controls concrete flow, avoiding waste. The gradually decreasing size of the flared opening allows for uniform concrete filling of the rigid frame 21, reducing voids and air bubbles, and improving concrete density and quality. The shape of the flared opening also makes the connection points smoother and more balanced, enhancing aesthetics and increasing the overall visual appeal of the building.

[0039] In order to achieve the self-support action of the two side formwork 23 during the installation of the casting connection device 2, the formwork self-support device 3 is set up, including tie rods 31. The top and bottom surfaces of the rigid frame 21 are fixedly welded to the arc surface of the tie rods 31. Multiple tie rods 31 are linearly arranged on the surface of the side formwork 23. The multiple tie rods 31 are also set in two groups, and the two groups are arranged vertically. The length of the upper group of tie rods 31 is greater than the length of the lower group of tie rods 31.

[0040] Specifically, by fixing and welding the tie rods 31 to the top and bottom of the rigid frame 21, stable support can be provided. The linear arrangement of the tie rods 31 can evenly distribute the load and effectively prevent deformation and tilting of the side formwork 23, ensuring the stability of the formwork during the pouring process; the upper and lower sets of tie rods 31 have different lengths, which allows for adjustment of the formwork tilt angle. By flexibly adjusting the selection and installation position of the tie rods 31, construction requirements with different tilt angles can be met.

[0041] The design of the self-supporting formwork device 3 allows the side formwork 23 to be self-supporting, eliminating the need for additional support rods or brackets. This simplifies the construction process, reduces labor and material usage, and improves construction efficiency; it also ensures the stability and accuracy of the formwork, guaranteeing that the position and shape of the formwork meet design requirements during concrete pouring. This improves construction quality and reduces structural defects and quality problems caused by formwork deformation or instability.

[0042] Both ends of the multiple pull rods 31 are threaded with tapered helical tubes 32. The two tapered helical tubes 32 threaded at both ends of each pull rod 31 are located on the inner side of the two side templates 23 respectively. The other end of the multiple tapered helical tubes 32 is threaded with an adjusting screw 33. One end of the adjusting screw 33 passes through and extends to the outer surface of the side template 23. A pad 34 is movably fitted on the arc surface of the adjusting screw 33. A locking nut 35 is provided on one side of the pad 34. The inner wall of the locking nut 35 is threadedly connected to the surface of the adjusting screw 33. The multiple adjusting screws 33 are composed of multiple left-handed adjusting screws 33 and multiple right-handed adjusting screws 33 respectively.

[0043] Specifically, the tapered helical tube 32 ensures a secure connection between the tie rod 31 and the side formwork 23. By adjusting the screw 33, the tie rod 31 can be tightly fitted to the side formwork 23, providing stable support and ensuring the alignment of the side formwork 23. This helps prevent formwork deformation or tilting, ensuring accuracy and stability during construction. Due to the tapered helical tube 32 and threaded connection design, the tie rod 31 and adjusting screw 33 can be relatively easily disassembled and installed. This facilitates formwork adjustment and replacement, adapting to different construction needs. Simultaneously, the adjusting screw 33 allows for fine-tuning during construction, maintaining formwork stability. The use of the adjusting screw 33 and shim 34 reduces the need for traditional support rods or brackets, simplifying the construction process and saving time and manpower.

[0044] To achieve synchronous drive adjustment during the operation of the template self-supporting device 3, a synchronous drive adjustment device 4 is provided, including a limiting and fixing clamping block 41. Multiple limiting and fixing clamping blocks 41 are provided, and each limiting and fixing clamping block 41 is located on one side of multiple pads 34. A clamping groove 42 is provided at the bottom of the limiting and fixing clamping block 41. The inner wall of the clamping groove 42 is slidably inserted into the surface of the side template 23. A locking screw 43 is threadedly connected to one side of the inner wall of the clamping groove 42. The pressing end of the locking screw 43 is pressed against the surface of the side template 23.

[0045] Specifically, the limiting and fixing clamping block 41 is slidably inserted into the surface of the side template 23 through the clamping groove 42 and fixed by the locking screw 43. This ensures that the clamping block remains stable in the selected position and will not move or deviate unexpectedly.

[0046] A limiting plate 44 is fixedly installed on the top of the limiting and fixing clamping block 41. A slide rail 45 is fixedly installed on the surface of the limiting plate 44. A sliding plate 46 is slidably inserted into the surface of the slide rail 45. A clamping plate 47 is rotatably connected to one end of the sliding plate 46 through a turntable bearing.

[0047] Specifically, the clamping plate 47 is connected to the sliding plate 46 through the turntable bearing, which can achieve 360-degree rotation. Since the clamping plate 47 can rotate and be adjusted freely, multiple clamping plates 47 can be used simultaneously to drive multiple locking nuts 35 to lock synchronously during construction.

[0048] A slot 48 is provided on one side surface of the clamp 47. The inner wall of the slot 48 is hexagonal and a through hole 49 is provided on the inner wall of the slot 48. The inner wall of the through hole 49 is movably sleeved with the arc surface of the adjusting screw 33. An adjusting hole 410 is provided on the inner side wall of the slot 48. A pressing rod 411 is slidably inserted into the inner wall of the adjusting hole 410. A driven sprocket 412 is fixedly installed on the arc surface of the other end of the clamp 47.

[0049] Specifically, by adjusting the screw 33 to slide within the through hole 49, the clamping plate 47 can move back and forth along the axis of the adjusting screw 33 after clamping the locking nut 35; a driven sprocket 412 is fixedly installed at the other end of the clamping plate 47, and the driven sprocket 412 is synchronously controlled to rotate in the synchronous drive, thereby achieving the effect of rotating the clamping plate 47.

[0050] Each of the three extrusion rods 411 has an extrusion plate 413 fixedly installed at one end. A spring 414 is fixedly installed on one side surface of the extrusion plate 413. One end of the spring 414 contacts the inner wall of the slot 48, and the inner ring of the spring 414 is movably sleeved with the arc surface of the extrusion rod 411. The surface of each of the three extrusion plates 413 is pressed against the outer surface of a locking nut 35.

[0051] Specifically, the pressing plate 413 contacts the inner wall of the slot 48 via a spring 414, which provides uniform pressure. This ensures that the clamped object receives a uniform and stable force during clamping. The surface of the pressing plate 413 presses against the outer surface of the locking nut 35, increasing the stability and firmness of the clamping force. This prevents the clamping disc 47 from loosening or slipping during operation, ensuring a stable and long-lasting clamping force. Furthermore, the pressing plate 413 presses against the surface of the locking nut 35 during the rotation of the clamping disc 47, causing the locking nut 35 to rotate accordingly.

[0052] Two limiting plates 44 are installed on the top and bottom left side of the side template 23. Connecting rods 415 are fixedly installed on their surfaces. Guide plates 416 are fixedly installed on opposite ends of the two connecting rods 415. Guide rails 417 are fixedly installed on the surface of the guide plates 416. Threaded rods 418 are rotatably connected to both ends of the guide plates 416 through bearings. One end of the threaded rod 418 passes through and extends to the outside of the guide plates 416. An auxiliary motor 419 is fixedly installed on the surface of the guide plates 416. The output shaft of the auxiliary motor 419 is fixedly installed to one end of the threaded rod 418 through a coupling.

[0053] Specifically, this implementation achieves the effect of using an auxiliary motor 419 to assist in the operation of multiple clamping discs 47 to control the locking nut 35 to move linearly on the surface of the adjusting screw 33, thereby driving the threaded rod 418 to rotate and achieve synchronous rotation.

[0054] Auxiliary slide plates 420 are slidably inserted into the surfaces of both guide rails 417. The surface of the auxiliary slide plate 420 is threadedly connected to the surface of the threaded rod 418. A synchronous rotary motor 421 is fixedly installed at one end of the auxiliary slide plate 420. A sprocket shaft 422 is fixedly installed on the output shaft of the synchronous rotary motor 421 through a coupling. A drive sprocket 423 is fixedly installed at one end of the sprocket shaft 422. A chain 424 is drivingly connected to the surface of the drive sprocket 423 on the surfaces of multiple driven sprockets 412.

[0055] Specifically, when the threaded rod 418 rotates, it drives the auxiliary slide plate 420 on the surface of the guide rail 417 to slide, thereby driving the drive sprocket 423 to move. The displacement of the drive sprocket 412 is matched with that of the driven sprocket 412 to achieve synchronous movement. Then, the rotation of the drive sprocket 423 synchronously drives the rotation of multiple driven sprockets 412, which in turn drives multiple locking nuts 35 to lock and clamp.

[0056] This device incorporates a self-supporting formwork device 3 during the concrete pouring of multi-directional inclined tower limbs. This self-supporting effect ensures the formwork is subjected to tension and compression during the concrete pouring process, guaranteeing structural safety and stability. The rigid frame 21 serves as the primary load-bearing structure for formwork support, achieving structural uniformity, eliminating the need for lateral formwork support, reducing workload, and improving the efficiency of segmented tower limb construction. The use of weldable tie rods 31 and tapered nuts ensures standardized tie rod 31 holes, aesthetically pleasing sealing, and a high-quality concrete appearance.

[0057] Furthermore, the synchronous drive adjustment device 4 can simultaneously control the locking operation of multiple locking nuts 35, avoiding the time wasted by adjusting and locking each nut individually, thereby improving production efficiency. Under synchronous control, multiple locking nuts 35 can maintain a consistent locking force, preventing damage to the template installation or loosening due to inconsistent locking forces caused by different operators. The synchronous drive adjustment device 4 can automatically complete the locking operation of multiple locking nuts 35, reducing the labor intensity and fatigue of operators.

[0058] Reference Figures 1-9 A construction method for a self-supporting mechanism for concrete formwork of a multi-directional inclined tower leg: Step 1: Complete the binding and welding of the stiffening frame 21 at both ends in sequence. Install the formwork in sequence from the top and fix it temporarily. When installing the side formwork 23, connect the tapered screw tube 32 to the adjusting screw 33 through the formwork self-supporting device 3. Then install the tie rod 31 on the inner side of the threaded connection and weld it to the surface of the stiffening frame 21. Weld the tie rod 31 to fix it.

[0059] Step 2: After the tie rod 31 is welded and fixed, the clamping slot 42 of the synchronous drive adjustment device 4 is used to control multiple limiting and fixing clamping blocks 41 to be installed on the surface of the side template 23. The locking screw 43 is used to lock and fix them, so that the limiting and fixing clamping blocks 41 are installed and locked. The slot 48 of the control plate 47 is engaged with the surface of the locking nut 35, and the surfaces of the three extrusion plates 413 are driven to be pressed against the surface of the locking nut 35 under the reverse extrusion force of the spring 414.

[0060] Step 3: After the multiple clamping plates 47 are engaged with the locking nuts 35 that are threaded to one end of each adjusting screw 33, they are all kept stationary in the initial moving position of the slide rail 45. The chain control drive sprocket 423 and multiple driven connections are connected in series and located on the same horizontal plane.

[0061] Step 4: Simultaneously drive the auxiliary motor 419 and the synchronous rotary motor 421 to work. The synchronous rotary motor 421 drives the sprocket shaft 422 to rotate, which in turn drives the drive sprocket 423 to rotate. The drive sprocket 423 then drives the chain drive to synchronously control the rotation of multiple sprockets, which in turn synchronously drive the rotation of multiple clamping plates 47. This controls the synchronous rotation and locking operation of the internally engaged locking nuts 35. As the multiple locking nuts 35 rotate and move synchronously, they drive the multiple clamping plates 47 to move towards the limiting and fixing clamping block 41, which then rotates and cooperates with the auxiliary motor 419. Through the rotation and cooperation of the auxiliary motor 419, the threaded rod 418 is driven to rotate, which in turn drives the auxiliary slide plate 420 with the surface thread connection to move synchronously with the multiple clamping plates 47.

[0062] Step 5: After multiple locking nuts 35 are locked in sync, stop working and wait for concrete pouring. When disassembly is required after pouring, control the synchronous rotary motor 421 and auxiliary motor 419 to reverse the operation, which will drive the locking nuts 35 to move in reverse for disassembly. After the locking nuts 35 are disassembled, the limit fixing clamping block 41 is disassembled by loosening the locking screw 43. The side template 23 can be disassembled by disassembling the adjusting screw 33.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

7. The construction method of a self-supporting mechanism for concrete formwork of a multi-directional inclined tower leg according to claim 6, characterized in that: Step 1: Complete the binding and welding of the rigid frame (21) in sequence. Install the templates in sequence from the top and fix them temporarily. When installing the side template (23), use the template self-support device (3) to connect the tapered screw tube (32) to the adjusting screw (33) threadedly. Then install the tie rod (31) on the inner side of the threaded connection and weld it to the surface of the rigid frame (21). Weld the tie rod (31) to fix it. Step 2: After the tie rod (31) is welded and fixed, the clamping slot (42) of the synchronous drive adjustment device (4) is used to control multiple limiting and fixing clamping blocks (41) to be installed on the surface of the side template (23). The locking screw (43) is used to lock and fix them, so that the limiting and fixing clamping blocks (41) are installed and locked. The slot (48) of the control plate (47) is engaged with the surface of the locking nut (35), and the surfaces of the three extrusion plates (413) are driven to be pressed against the surface of the locking nut (35) under the reverse extrusion force of the spring (414). Step 3: After the multiple clamps (47) are engaged with the locking nuts (35) that are threaded to one end of each adjusting screw (33), they are all kept still in the initial moving position of the slide rail (45) and the chain control drive sprocket (423) and multiple driven connections are connected in series and located on the same horizontal plane. Step 4: Simultaneously drive the auxiliary motor (419) and the synchronous rotary motor (421) to work. The synchronous rotary motor (421) drives the sprocket shaft (422) to rotate, thereby the sprocket shaft (422) rotates and drives the drive sprocket (423) to rotate. In turn, the drive sprocket (423) drives the chain drive to synchronously control the rotation of multiple sprockets, thereby synchronously driving multiple clamping plates (47) to rotate. Control the locking nut (35) inside to rotate synchronously and lock. In the synchronous rotation and movement of multiple locking nuts (35), multiple clamping plates (47) are driven to move towards the limiting and fixing clamping block (41), thereby cooperating with the rotation of the auxiliary motor (419). Through the rotation and cooperation of the auxiliary motor (419), the threaded rod (418) is driven to rotate, thereby driving the auxiliary slide plate (420) with the surface thread connection to move synchronously with multiple clamping plates (47). Step 5: After multiple locking nuts (35) are locked in sync, stop working and wait for concrete pouring. When disassembly is required after pouring, control the synchronous rotary motor (421) and auxiliary motor (419) to reverse the operation, which will drive the locking nuts (35) to move in reverse for disassembly. After the locking nuts (35) are disassembled, the limit fixing clamp (41) is disassembled by loosening the locking screw (43). The side template (23) can be disassembled by disassembling the adjusting screw (33).
