Description

Technical Field

[0001] The present invention relates to the technical field of construction concrete formwork, in particular to a combined adjustable column formwork and a construction method thereof. Background Art

[0002] In the field of construction formwork engineering, column formwork is an indispensable temporary structural component in the construction of concrete column structures. Its function is to constrain and shape unset concrete until it reaches sufficient strength to bear its own load. At present, commonly used column formwork systems mainly include wooden plywood formwork, steel formwork, aluminum formwork and some combined plastic formwork, etc. In the construction field of cast-in-situ concrete frame columns and structural columns, the formwork support system is the core structure that guarantees the molding size, verticality and overall stability of the column, and directly determines the quality and safety of concrete pouring construction. At present, the supporting systems matched with existing adjustable and fixed column formworks mostly adopt the traditional combined structure of scattered-assembled inclined supports and vertical top supports. For a long time, there are many technical defects such as poor support adaptability, insufficient stability, cumbersome disassembly and assembly, and low molding accuracy, which seriously restrict the popularization and application of prefabricated and modular formwork construction technology. The specific technical problems are as follows:

[0003] First, the size of the existing formwork support structure is fixed, which has extremely poor adaptability to the adjustable column formwork and cannot match the size adjustment characteristic of the formwork. The inclined support and vertical support of traditional column formwork are mostly standard fixed-length pipes and square wood supports, which can only adapt to column formwork with a single fixed cross-section and fixed height. However, the existing adjustable column formwork can realize flexible adjustment of column cross-section and pouring height, the overall outer contour size and installation position of the formwork will be fine-tuned with construction parameters, and the fixed-length support cannot perform adaptive adaptation along with the adjustment stroke of the formwork. In construction, adaptation and installation can only be achieved by cutting supporting pipes on site, adding cushion wood and overlapping square wood, which not only causes a large amount of waste of supporting materials, but also the non-standard supporting components after cutting cannot be reused for secondary turnover, greatly increasing construction cost. Moreover, the manual adaptation adjustment accuracy is extremely poor, and problems such as support eccentricity and uneven stress are very prone to occur.

[0004] In view of the above-mentioned related art, the inventor believes that the following defects exist: in summary, the support cannot be adaptively matched with the adjustable size of the formwork, and can only be adapted by means of cushion wood and cutting piecing together, which is very easy to cause deviation of support top points, eccentric stress, and uneven pre-tightening force of four-sided supports. When concrete pouring is subjected to lateral pressure, local stress concentration and stress imbalance of the formwork occur, and the overall ability to resist lateral displacement and mold expansion is significantly reduced. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a combined adjustable column formwork.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a combined adjustable column template, including a frame, wherein multiple frames are provided, and each frame is fixed with a plywood. Multiple mounting holes are provided on the plywood, and a first screw is inserted into the mounting hole. An L-shaped abutment is inserted through the first screw, and a large nut washer threadedly connected to the first screw is sleeved on the first screw. The L-shaped abutment is engaged with the side wall of the frame, and multiple inclined support mechanisms are provided on the frame.

[0007] By adopting the above technical solution, workers take a single frame piece, snap-fit ​​the L-shaped abutment block into the corresponding slot on the side wall of the frame, align it with the pre-drilled mounting holes in the plywood, pass the first screw through the mounting hole and the L-shaped abutment block, and fit a large nut washer on the outside of the first screw. Slightly tighten the large nut washer to temporarily fix the L-shaped abutment block, completing the pre-assembly of one side frame. Based on the column's designed cross-sectional dimensions, select the corresponding number of pre-assembled frames and arrange them along the column's outline. Adjacent frames are joined together by the L-shaped abutment blocks at their ends, forming a closed columnar casting mold cavity. An inclined support mechanism is installed to support the frame, preventing it from shifting and ensuring uniform stress distribution. This application changes the traditional technology that relies solely on wooden blocks and cutting and piecing together materials to fit the template size and provide support, ensuring the reliability of the support.

[0008] Furthermore, each of the inclined support mechanisms includes a first inclined reinforcement component, which includes a mounting plate disposed on one side of the frame, a reinforcement sleeve fixed to the top of the mounting plate, a partition fixed inside the reinforcement sleeve, a first reinforcement screw that passes through the partition and rotatably engages with the partition, a first threaded cylinder sleeved on the first reinforcement screw and threadedly connected to the first reinforcement screw, a first mounting cylinder hinged to the end of the first threaded cylinder away from the reinforcement sleeve, a first reinforcement rod slidably disposed inside the first mounting cylinder, and a first U-shaped guide plate hinged to the end of the first reinforcement rod near the frame. The first U-shaped guide plate is connected to the side wall of the frame, and the first threaded cylinder slidably engages with the inner wall of the reinforcement sleeve. The inclined support mechanism also includes a second inclined reinforcement component.

[0009] Furthermore, the second inclined reinforcement component includes a second reinforcement screw that passes through the partition and rotatably engages with the partition, a second threaded cylinder that is sleeved on the second reinforcement screw and threadedly connected to the second reinforcement screw, a second mounting cylinder that is hinged to the end of the second threaded cylinder away from the reinforcement sleeve, a second reinforcement rod that is slidably disposed in the second mounting cylinder, and a second U-shaped guide plate that is hinged to the end of the second reinforcement rod near the frame. The second U-shaped guide plate is connected to the side wall of the frame. The inclined support mechanism also includes a first linkage component.

[0010] By adopting the above technical solution, rotating the first reinforcing screw causes the first threaded cylinder to slide linearly towards the frame along the fixed inner wall of the reinforcing sleeve due to the threaded engagement. The first threaded cylinder drives the hinged first mounting cylinder and the locked-length first reinforcing rod to move towards the frame together. Then, the hinged first U-shaped guide plate pushes against the side wall of the frame, forming an oblique support force. When the second reinforcing screw is rotated synchronously, the second threaded cylinder slides synchronously along the inner wall of the reinforcing sleeve, driving the second mounting cylinder, the locked-length second reinforcing rod, and the second U-shaped guide plate to move forward synchronously, pressing against the side wall of the frame from the other side, and simultaneously correcting the frame. If unilateral fine adjustment is required, the transmission linkage of the first reinforcing screw can be disconnected through the first linkage component, driving only the second reinforcing screw to rotate, and only the second oblique reinforcing component to move forward and push against the frame. Conversely, disconnecting the linkage of the second reinforcing screw will drive only the first oblique reinforcing component to correct the frame on one side.

[0011] Furthermore, the first linkage assembly includes a first linkage ring sleeved on the first reinforcing screw and splinedly connected to the first reinforcing screw, a first abutting ring fixed to the side wall of the first linkage ring, a first push plate fixed to the side wall of the first abutting ring, and a first positioning rod fixed to the side of the first linkage ring away from the first abutting ring. Multiple first positioning rods are provided. A first through hole is provided through the reinforcing sleeve for the first push plate to slide. The first linkage assembly also includes a first spring fixed to the inner wall of the first through hole, a first rotating rod rotatably installed on the inner wall of the reinforcing sleeve, and a first gear fixedly sleeved on the first rotating rod. A first slot is provided on the first gear for the first positioning rod to be inserted and engaged. Multiple first slots are provided and correspond one-to-one with the first positioning rod. The inclined support mechanism also includes a second linkage assembly.

[0012] Furthermore, the second linkage assembly includes a second linkage ring sleeved on the second reinforcing screw and splinedly connected to the second reinforcing screw, a second abutting ring fixed to the side wall of the second linkage ring, a second push plate fixed to the side wall of the second abutting ring, and a second positioning rod fixed to the side of the second linkage ring away from the second abutting ring. Multiple second positioning rods are provided. The reinforcing sleeve has a second through hole through which the second push plate slides. The second linkage assembly also includes a second spring fixed to the inner wall of the second through hole, a second rotating rod rotatably mounted on the inner wall of the reinforcing sleeve, and a second gear fixedly sleeved on the second rotating rod. The second gear has a second slot for the second positioning rod to be inserted and engaged. Multiple second slots are provided and correspond one-to-one with the second positioning rod. The inclined support mechanism also includes a drive assembly for driving two adjacent first reinforcing screws and second reinforcing screws to rotate synchronously or controlling the rotation of the first reinforcing screws and second reinforcing screws individually.

[0013] Furthermore, the drive assembly includes a worm gear fixedly sleeved on the first rotating rod, a drive rod rotatably mounted on the inner wall of the reinforced sleeve, a transmission wheel fixedly sleeved on the drive rod and meshing with both the first gear and the second gear, a side plate fixedly mounted on the side wall of the reinforced sleeve, a worm rotatably mounted on the side plate and meshing with the worm gear, and a connecting block fixedly sleeved on the worm.

[0014] By adopting the above technical solution, when the first reinforcing screw and the second reinforcing screw need to be driven to rotate synchronously, the first push plate and the second push plate are released. The first spring pushes the first push plate, and the second spring in the second through hole pushes the second push plate. The first push plate drives the first linkage ring to slide through the first clamping ring. The first positioning rod is inserted into the first slot. The first linkage ring and the first reinforcing screw rotate synchronously by means of spline connection. Similarly, the second push plate drives the second linkage ring to slide through the second clamping ring. The second positioning rod is inserted into the second slot. The second linkage ring and the second reinforcing screw rotate synchronously by means of spline connection. The operator rotates the block, which drives the worm to rotate. The worm meshes with the worm wheel and drives the first rotating rod to rotate. The first gear fixed on the first rotating rod rotates synchronously. The drive rod rotates on the inner wall of the reinforcing sleeve. The transmission wheel on the drive rod meshes with the first gear and the second gear at the same time. The first gear and the second gear rotate synchronously in the same direction. When the rotation of the first reinforcing screw needs to be controlled independently, the second push plate is pressed, compressing the second spring. The second push plate, through the second clamping ring, drives the second linkage ring to slide, causing the second positioning rod to disengage from the second slot of the second gear. The second linkage ring is disconnected from the transmission of the second gear, and the second reinforcing screw is disengaged from the transmission control. The first push plate is kept free from external pressure, and the first spring continues to push the first push plate. The first positioning rod remains inserted in the first slot of the first gear, and the first reinforcing screw and the first gear maintain transmission linkage. The rotating block drives the worm and worm wheel to rotate, and the transmission wheel simultaneously meshes with the first gear and the second gear. Only the first gear can drive the first linkage ring and the first reinforcing screw to rotate independently through the first positioning rod. Only the first inclined reinforcing component outputs pushing force to correct the unilateral offset of the frame independently. When the rotation of the second reinforcing screw needs to be controlled independently, press the first push plate. The first push plate compresses the first spring. The first push plate drives the first linkage ring to slide through the first clamping ring, causing the first positioning rod to disengage from the first slot of the first gear. The first linkage ring is disconnected from the transmission of the first gear, and the first reinforcing screw is disengaged from the transmission control. Release the second push plate, and the second spring pushes the second push plate. The second positioning rod remains inserted in the second slot of the second gear. The second reinforcing screw and the second gear maintain transmission linkage. The rotating block drives the worm and worm wheel to rotate. The transmission wheel meshes with the first gear and the second gear synchronously. Only the second gear can drive the second linkage ring and the second reinforcing screw to rotate independently through the second positioning rod. Only the second inclined reinforcing component outputs the pushing force to correct the offset on the other side of the frame independently.

[0015] Furthermore, the frame is provided with a connecting component for fixing two adjacent frames. The connecting component includes a connecting plate that fits against the side walls of the two adjacent frames, a first locking block fixed to the connecting plate, a U-shaped slider that slides on the connecting plate, and a second locking block fixed to the U-shaped slider. The side of the first locking block and the second locking block that are close to each other presses against the side walls of the two adjacent frames. The connecting plate is provided with a stop component for fixing the U-shaped slider.

[0016] Furthermore, the stop assembly includes a stop block fixed to the side of the connecting plate away from the frame. Multiple stop blocks are provided. A through hole is provided on the U-shaped slider. The stop assembly also includes an insert rod inserted into the through hole and engaging with the stop block. A limit plate is fixed to the top of the insert rod.

[0017] By adopting the above technical solution, workers place the U-shaped slider onto the connecting plate and attach the connecting plate to the side walls of two adjacent frames. Moving the connecting plate causes the first locking block to press against the side wall of the frame. Then, pushing the U-shaped slider moves it, causing the second locking block to move synchronously. The first and second locking blocks move closer together, pressing against the side walls of the two adjacent frames. A rod is inserted through a hole in the U-shaped slider, engaging with a stop block fixed to the connecting plate. This stop component secures the U-shaped slider, preventing it from sliding or shifting, thus fixing the two adjacent frames. During demolding, the rod is first pulled out to release the engagement between it and the stop block, releasing the U-shaped slider's limit. Then, the U-shaped slider is pushed in the opposite direction, causing the first and second locking blocks to loosen from the side wall of the frame. Finally, the connecting plate is removed, completing the disassembly of the connecting component. Simultaneously, a limiting plate fixed to the top of the rod provides vertical restraint, preventing the rod from slipping out of the hole in the U-shaped slider during construction vibrations or frame swaying.

[0018] Furthermore, a first rod is inserted through the first mounting cylinder, and a first insertion hole is provided on the first reinforcing rod for insertion and engagement of the first rod. Multiple first insertion holes are provided. A second rod is inserted through the second mounting cylinder, and a second insertion hole is provided on the second reinforcing rod for insertion and engagement of the second rod. Multiple second insertion holes are provided.

[0019] By adopting the above technical solution, the first reinforcing rod slides in the first mounting sleeve and the second reinforcing rod slides in the second mounting sleeve according to the actual distance between the frame and the reinforcing sleeve. By inserting the first rod into the first insertion hole at different positions and the second rod into the second insertion hole at different positions, the extension length of the first and second reinforcing rods can be coarsely adjusted in multiple positions, which can adapt to the needs of adjustable column formwork with different cross-sectional sizes and different installation heights.

[0020] A method for constructing a combined adjustable column formwork includes the following steps:

[0021] S1. Pre-construction preparation: First, snap the L-shaped abutment block into the corresponding slot on the side wall of the frame, align the mounting holes on the plywood, insert the first screw into the mounting hole and the L-shaped abutment block, screw the large nut washer onto the first screw to complete the temporary fixation of the L-shaped abutment block, select the corresponding number of pre-assembled frames according to the column cross-section size, and at the same time configure two sets of diagonal support mechanisms for lateral reinforcement of the frame.

[0022] S2. Frame enclosure assembly: Multiple pre-assembled frames are arranged sequentially along the column outline to enclose and form a column mold cavity; the side walls of two adjacent frames are attached together, and a connecting plate is attached to the side wall of the adjacent frame assembly. The first clip on the connecting plate abuts against one side wall of the frame, and the U-shaped slider on the connecting plate is slid to make the second clip on the U-shaped slider press against the other side wall of the frame. The first clip and the second clip are used to clamp the adjacent frames to complete the initial splicing and positioning.

[0023] S3. Locking and fixing at the splice: The stop assembly is operated to complete the U-shaped slider limit. The insert rod with the limit plate is passed through the hole on the U-shaped slider, so that the insert rod is engaged with the stop block on the outside of the connecting plate, fixing the position of the U-shaped slider, locking the relative position of the adjacent frame, and eliminating the splice gap; at the corner of the column mold, tighten the large nut washer on the first screw, lock the L-shaped stop block, and close the corner gap of the column mold.

[0024] S4. Assembly and installation of the inclined support mechanism: Fix the mounting plates of the two sets of inclined support mechanisms to the ground base. Hinge the first U-shaped guide plate to the corresponding point on the side wall of the frame. Connect the first U-shaped guide plate to the first reinforcing rod. The first reinforcing rod slides through the inside of the first mounting cylinder. Hinge the second U-shaped guide plate to the point on the other side wall of the frame. Connect the second U-shaped guide plate to the second reinforcing rod. The second reinforcing rod slides through the inside of the second mounting cylinder. Extend and retract the first reinforcing rod and the second reinforcing rod according to the height of the column. Insert the first rod into the first mounting cylinder and insert it into the corresponding first insertion hole on the first reinforcing rod. Insert the second rod into the second mounting cylinder and insert it into the corresponding second insertion hole on the second reinforcing rod. Lock the extension length of the reinforcing rod.

[0025] S5. Support for synchronous or individual adjustment: Drive assembly operation steps: Rotate the block on the side plate, the block drives the worm to rotate, the worm meshes with the worm wheel to rotate synchronously, the worm wheel drives the first rotating rod and the first gear to rotate, and the transmission wheel simultaneously meshes with the first gear and the second gear. When synchronous adjustment is required: the first spring and the second spring push the first push plate and the second push plate respectively, so that the first positioning rod on the first linkage ring inserts into the first slot of the first gear, and the second positioning rod on the second linkage ring inserts into the second slot of the second gear. The first reinforcing screw and the second reinforcing screw follow the first gear. The second gear rotates synchronously, and the first and second threaded cylinders slide synchronously along the inner wall of the reinforcing sleeve, simultaneously pressing against the two side frames to uniformly correct the verticality of the frames. When individual adjustment is required: press the first push plate to compress the first spring, causing the first positioning rod to disengage from the first slot, disconnecting the linkage between the first reinforcing screw and the transmission wheel, and only the second reinforcing screw adjusts with the transmission wheel; or press the second push plate to compress the second spring, causing the second positioning rod to disengage from the second slot, disconnecting the transmission linkage between the second reinforcing screw and the second gear, and independently controlling the first reinforcing screw to push against the frame, specifically correcting the offset of one side of the frame.

[0026] S6. Demolding, Transfer, and Storage: After the column concrete reaches the specified demolding strength, reverse the upper operation to dismantle the frame; first, rotate the connecting block to loosen the worm gear transmission, press the first and second push plates to release the linkage, rotate the first and second reinforcing screws in the reverse direction, retract the first and second reinforcing rods, pull out the first and second rods to loosen the reinforcing rod length limit, pull out the insert rod to disengage from the stop block, slide the U-shaped slider to loosen the adjacent frame clamping structure; unscrew the large nut washer, remove the L-shaped stop block, disassemble multiple sets of frames, disassemble all components, clean the concrete residue on each component, and classify and store them for future reuse.

[0027] In summary, the present invention has the following beneficial effects: Workers take a single frame piece, snap-fit ​​the L-shaped abutment block to the corresponding slot on the side wall of the frame, align the pre-drilled mounting holes in the plywood, pass the first screw through the mounting hole and the L-shaped abutment block, fit a large nut washer on the outside of the first screw, and slightly tighten the large nut washer to temporarily fix the L-shaped abutment block, completing the pre-assembly of a single-side frame. Based on the column's designed cross-sectional dimensions, select the corresponding number of pre-assembled frames and arrange them along the column's outline. Adjacent frames are joined together by the L-shaped abutment blocks at their ends, forming a closed columnar casting cavity. An inclined support mechanism is installed to support the frame, preventing it from shifting and ensuring uniform stress distribution. Attached Figure Description

[0039] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0040] like Figure 1-10 As shown in the illustration, this application discloses a combined adjustable column template, including a frame 1, plywood 11, a first screw 12, an L-shaped abutment 13, a large nut washer 14, and a diagonal support mechanism 2. Multiple frames 1 are provided, and a plywood 11 is fixed to each frame 1. Multiple mounting holes 111 are provided on the plywood 11. The first screw 12 passes through the mounting hole 111, and the L-shaped abutment 13 passes through the first screw 12. The large nut washer 14 is sleeved on the first screw 12 and threadedly connected to the first screw 12. The L-shaped abutment 13 engages with the side wall of the frame 1, and multiple diagonal support mechanisms 2 are provided on the frame 1.

[0041] Workers take a single frame 1, snap-fit ​​the L-shaped abutment 13 onto the corresponding slot on the side wall of the frame 1, align the pre-drilled mounting holes 111 on the plywood 11, pass the first screw 12 through the mounting holes 111 and the L-shaped abutment 13, fit a large nut washer 14 on the outside of the first screw 12, and slightly tighten the large nut washer 14 to temporarily fix the L-shaped abutment 13, thus completing the pre-assembly of one side frame 1. Based on the column design cross-sectional dimensions, select the corresponding number of pre-assembled frames 1 and arrange them around the column outline. Adjacent frames 1 are joined together by the L-shaped abutments 13 at their ends to form a closed column-shaped casting mold cavity. The frame 1 is supported by the installed inclined support mechanism 2 to prevent the frame 1 from shifting and to ensure that the frame 1 is subjected to uniform force.

[0042] The inclined support mechanism 2 includes a first inclined reinforcement component 21, a second inclined reinforcement component 22, a first linkage component 23, a second linkage component 24, and a drive component 25. The first inclined reinforcement component 21 includes a mounting plate 211, a reinforcement sleeve 212, a partition plate 213, a first reinforcement screw 214, a first threaded cylinder 215, a first mounting cylinder 216, a first reinforcement rod 217, and a first U-shaped guide plate 218. The mounting plate 211 is disposed on one side of the frame 1, and the reinforcement sleeve 212 is fixed to the top of the mounting plate 211. The partition plate 213 is fixed inside the reinforcement sleeve 212, and the first reinforcement screw 214 passes through the partition plate 213 and rotatably engages with the partition plate 213. The first threaded cylinder 215 is sleeved on the first reinforcement screw 214, and the first threaded cylinder 215 is threadedly connected to the first reinforcement screw 214. The first mounting cylinder 216 is hinged to the end of the first threaded cylinder 215 away from the reinforcing sleeve 212, and the first reinforcing rod 217 is slidably disposed inside the first mounting cylinder 216. The first U-shaped guide plate 218 is hinged to the end of the first reinforcing rod 217 near the frame 1, and the first U-shaped guide plate 218 is connected to the side wall of the frame 1. The first threaded cylinder 215 is slidably engaged with the inner wall of the reinforcing sleeve 212.

[0043] The second inclined reinforcement component 22 includes a second reinforcing screw 221, a second threaded cylinder 222, a second mounting cylinder 223, a second reinforcing rod 224, and a second U-shaped guide plate 225. The second reinforcing screw 221 is threaded through the partition 213 and rotatably engages with it. The second threaded cylinder 222 is sleeved on the second reinforcing screw 221 and threadedly connected to it. The second threaded cylinder 222 also slidably engages with the inner wall of the reinforcing sleeve 212. The second mounting cylinder 223 is hinged to the end of the second threaded cylinder 222 away from the reinforcing sleeve 212, and the second reinforcing rod 224 is slidably disposed within the second mounting cylinder 223. The second U-shaped guide plate 225 is hinged to the end of the second reinforcing rod 224 near the frame 1 and is connected to the side wall of the frame 1.

[0044] Rotating the first reinforcing screw 214 causes the first threaded cylinder 215 to slide linearly towards the frame 1 along the inner wall of the fixed reinforcing sleeve 212 under the thrust of the thread. The first threaded cylinder 215 drives the hinged first mounting cylinder 216 and the locked length first reinforcing rod 217 to move towards the frame 1 together, and then pushes against the side wall of the frame 1 through the hinged first U-shaped guide plate 218, forming an oblique support force. When the second reinforcing screw 221 is rotated synchronously, the second threaded cylinder 222 slides synchronously along the inner wall of the reinforcing sleeve 212. The movement causes the second mounting cylinder 223, the second reinforcing rod 224 with locked length, and the second U-shaped guide plate 225 to move forward synchronously, pressing against the side wall of the frame 1 from the other side, and simultaneously correcting the frame 1. If a fine adjustment on one side is required, the transmission linkage of the first reinforcing screw 214 can be disconnected through the first linkage component 23, driving only the second reinforcing screw 221 to rotate, and only the second oblique reinforcing component 22 to move forward and push the frame 1. Conversely, the linkage of the second reinforcing screw 221 can be disconnected, driving only the first oblique reinforcing component 21 to correct the frame 1 on one side alone.

[0045] The first linkage assembly 23 includes a first linkage ring 231, a first clamping ring 232, a first push plate 233, a first positioning rod 234, a first spring 235, a first rotating rod 236, and a first gear 237. The first linkage ring 231 is sleeved on the first reinforcing screw 214, and the first linkage ring 231 is splinedly connected to the first reinforcing screw 214. The first clamping ring 232 is fixed to the side wall of the first linkage ring 231, and the first push plate 233 is fixed to the side wall of the first clamping ring 232. Multiple first positioning rods 234 are fixed to the side of the first linkage ring 231 away from the first clamping ring 232. A first through hole 2121 is provided through the reinforcing sleeve 212, allowing the first push plate 233 to slide. The first spring 235 is fixed to the inner wall of the first through hole 2121, and the first rotating rod 236 is rotatably mounted on the inner wall of the reinforcing sleeve 212. The first gear 237 is fixedly sleeved on the first rotating rod 236. The first gear 237 has a first slot 2371, which is used for the first positioning rod 234 to be inserted and engaged. Multiple first slots 2371 are provided and correspond one-to-one with the first positioning rod 234.

[0046] The second linkage assembly 24 includes a second linkage ring 241, a second clamping ring 242, a second push plate 243, a second positioning rod 244, a second spring 245, a second rotating rod 246, and a second gear 247. The second linkage ring 241 is sleeved on the second reinforcing screw 221, and the second linkage ring 241 is splinedly connected to the second reinforcing screw 221. The second clamping ring 242 is fixed to the side wall of the second linkage ring 241, and the second push plate 243 is fixed to the side wall of the second clamping ring 242. Multiple second positioning rods 244 are fixed to the side of the second linkage ring 241 away from the second clamping ring 242. A second through hole 2122 is provided in the reinforcing sleeve 2122, allowing the second push plate 243 to slide. The second spring 245 is fixed to the inner wall of the second through hole 2122, and the second rotating rod 246 is rotatably mounted on the inner wall of the reinforcing sleeve 212. The second gear 247 is fixedly sleeved on the second rotating rod 246. The second gear 247 has a second slot 2471, which is used for the second positioning rod 244 to be inserted and engaged. Multiple second slots 2471 are provided and correspond one-to-one with the second positioning rod 244.

[0047] The drive assembly 25 is used to drive two adjacent first reinforcing screws 214 and second reinforcing screws 221 to rotate synchronously or to control the rotation of the first reinforcing screws 214 and second reinforcing screws 221 individually. The drive assembly 25 includes a worm gear 251, a drive rod 252, a transmission wheel 253, a side plate 254, a worm 255, and a connecting block 256. The worm gear 251 is fixedly sleeved on the first rotating rod 236, and the drive rod 252 is rotatably mounted on the inner wall of the reinforcing sleeve 212. The transmission wheel 253 is fixedly sleeved on the drive rod 252, and the transmission wheel 253 meshes with both the first gear 237 and the second gear 247. The side plate 254 is fixedly mounted on the side wall of the reinforcing sleeve 212, the worm 255 is rotatably mounted on the side plate 254 and meshes with the worm gear 251, and the connecting block 256 is fixedly sleeved on the worm 255.

[0048] When the first reinforcing screw 214 and the second reinforcing screw 221 need to be driven to rotate synchronously, the first push plate 233 and the second push plate 243 are released. The first spring 235 pushes the first push plate 233, and the second spring 245 in the second through hole 2122 pushes the second push plate 243. The first push plate 233 drives the first linkage ring 231 to slide via the first abutting ring 232. The first positioning rod 234 is inserted into the first slot 2371. The spline connection enables the first linkage ring 231 and the first reinforcing screw 214 to rotate synchronously. Similarly, the second push plate 243 drives the second linkage ring 241 to slide via the second abutting ring 242. The second positioning rod 244 is inserted into the second slot 2471. The spline connection enables the second linkage ring 241 and the second reinforcing screw 221 to rotate synchronously. The operator rotates the assembly block 256, which drives the worm gear 255 to rotate. The worm gear 255 meshes with the worm wheel 251, which drives the first rotating rod 236 to rotate. The first gear 237 fixed on the first rotating rod 236 rotates synchronously. The drive rod 252 rotates on the inner wall of the reinforcing sleeve 212. The transmission wheel 253 on the drive rod 252 meshes with the first gear 237 and the second gear 247 at the same time. The first gear 237 and the second gear 247 rotate synchronously in the same direction. When the rotation of the first reinforcing screw 214 needs to be controlled independently, the second push plate 243 is pressed, compressing the second spring 245. The second push plate 243, via the second abutment ring 242, drives the second linkage ring 241 to slide, causing the second positioning rod 244 to disengage from the second slot 2471 of the second gear 247. The second linkage ring 241 is disconnected from the second gear 247, and the second reinforcing screw 221 is disengaged from the transmission control, keeping the first push plate 233 free from external pressure. The first spring 235 continues to push the first push plate 233. The first positioning rod 234 is inserted into the first slot 2371 of the first gear 237. The first reinforcing screw 214 maintains a transmission linkage with the first gear 237. The rotating block 256 drives the worm gear 255 and worm wheel 251 to rotate. The transmission wheel 253 synchronously meshes with the first gear 237 and the second gear 247. Only the first gear 237 can drive the first linkage ring 231 and the first reinforcing screw 214 to rotate independently through the first positioning rod 234. Only the first inclined reinforcing component 21 outputs a top thrust to correct the unilateral offset of the frame 1.When the rotation of the second reinforcing screw 221 needs to be controlled independently, the first push plate 233 is pressed, compressing the first spring 235. The first push plate 233, via the first abutment ring 232, drives the first linkage ring 231 to slide, causing the first positioning rod 234 to disengage from the first slot 2371 of the first gear 237. The first linkage ring 231 is disconnected from the first gear 237, and the first reinforcing screw 214 is disengaged from the transmission control. The second push plate 243 is then released, and the second spring 245 pushes against the second push plate 243, causing the second positioning rod 234 to disengage. Positioning rod 244 remains inserted in the second slot 2471 of second gear 247. Second reinforcing screw 221 maintains transmission linkage with second gear 247. Rotating block 256 drives worm 255 and worm wheel 251 to rotate. Transmission wheel 253 synchronously meshes with first gear 237 and second gear 247. Only second gear 247 can drive second linkage ring 241 and second reinforcing screw 221 to rotate independently through second positioning rod 244. Only second oblique reinforcing component 22 outputs top thrust to correct the offset on the other side of frame 1.

[0049] It should be noted that the inclined support mechanism 2 in this embodiment is not limited to the form of multiple sets used together. It can also be assembled on a single frame 1 and work independently. Through its integrated first inclined reinforcement component 21 and second inclined reinforcement component 22, it applies inclined support force to different points of a single frame 1 to achieve reinforcement and verticality correction of a single side frame 1. It can be adapted to construction scenarios such as temporary fixing of a single side frame 1 and adjustment of local frame 1 offset, and its use is flexible and adjustable.

[0050] In this embodiment, a connecting component 3 is provided on the frame 1. The connecting component 3 is used to fix two adjacent frames 1. The connecting component 3 includes a connecting plate 31, a first locking block 32, a U-shaped slider 33, and a second locking block 34. The connecting plate 31 is attached to the side walls of the two adjacent frames 1, and the first locking block 32 is fixed to the connecting plate 31. The U-shaped slider 33 is slidably disposed on the connecting plate 31, and the second locking block 34 is fixed to the U-shaped slider 33. The sides of the first locking block 32 and the second locking block 34 that are close to each other abut against the side walls of the two adjacent frames 1.

[0051] A stop assembly 4 is provided on the connecting plate 31. The stop assembly 4 is used to fix the U-shaped slider 33. The stop assembly 4 includes a stop block 41 and a rod 42. The stop block 41 is fixed to the side of the connecting plate 31 away from the frame 1, and multiple stop blocks 41 are provided. A through hole 331 is provided through the U-shaped slider 33. The rod 42 is inserted into the through hole 331 and is engaged with the stop block 41. The limiting plate 5 is fixed to the top of the rod 42.

[0052] The worker places the U-shaped slider 33 onto the connecting plate 31 and attaches the connecting plate 31 to the side walls of the two adjacent frames 1. Moving the connecting plate 31 causes the first locking block 32 to press against the side wall of the frame 1. Then, the worker pushes the U-shaped slider 33 to move, and the U-shaped slider 33 causes the second locking block 34 to move synchronously. The first locking block 32 and the second locking block 34 move closer to each other and press against the side walls of the two adjacent frames 1. The insert rod 42 passes through the through hole 331 on the U-shaped slider 33, so that the insert rod 42 and the stop block 41 fixed on the connecting plate 31 engage with each other. The stop component 4 is used to fix the U-shaped slider 33 and restrict the sliding displacement of the U-shaped slider 33, thereby fixing the two adjacent frames 1. During demolding, first pull out the insert rod 42 to release the engagement between the insert rod 42 and the stop block 41, thus releasing the U-shaped slider 33 from its limit position. Then, push the U-shaped slider 33 in the opposite direction to loosen the first locking block 32 and the second locking block 34 from the side wall of the frame 1. Finally, remove the connecting plate 31 to complete the disassembly of the connecting assembly 3. Simultaneously, the top of the insert rod 42 is fixed with a limiting plate 5, which provides vertical limiting and blocking for the insert rod 42, preventing it from slipping out of the through hole 331 of the U-shaped slider 33 when the frame 1 is subjected to construction vibration or shaking.

[0053] In this embodiment, a first rod 6 is inserted through the first mounting cylinder 216, and a first insertion hole 2171 is provided on the first reinforcing rod 217 for the first rod 6 to be inserted into.

Based on the actual distance between the frame 1 and the reinforcing sleeve 212, the first reinforcing rod 217 slides within the first mounting cylinder 216, and the second reinforcing rod 224 slides within the second mounting cylinder 223. By inserting the first rod 6 into the first insertion hole 2171 at different positions and the second rod 7 into the second insertion hole 2241 at different positions, multiple levels of coarse adjustment of the extension length of the first reinforcing rod 217 and the second reinforcing rod 224 are achieved, adapting to the needs of adjustable column formwork combinations with different cross-sectional dimensions and installation heights.

Select the corresponding number of pre-assembled frames 1 according to the column cross-section size, and at the same time configure two sets of diagonal support mechanisms 2 for lateral reinforcement of the frame 1.

[0056] S2, Frame 1 enclosure assembly: Multiple pre-assembled frames 1 are arranged sequentially along the column outline to enclose and form a column mold cavity; the side walls of two adjacent frames 1 are attached together, and the connecting plate 31 is attached to the side wall of the adjacent frame 1. The first locking block 32 on the connecting plate 31 abuts against the side wall of one frame 1, and the U-shaped slider 33 on the connecting plate 31 is slid to make the second locking block 34 on the U-shaped slider 33 press against the side wall of the other frame 1. The first locking block 32 and the second locking block 34 are used to clamp the adjacent frames 1 to complete the initial splicing and positioning;

[0057] S3. Locking and fixing at the splice: The stop assembly 4 is operated to limit the U-shaped slider 33. The insert rod 42 with the limit plate 5 is passed through the through hole 331 on the U-shaped slider 33, so that the insert rod 42 is engaged with the stop block 41 on the outside of the connecting plate 31, fixing the position of the U-shaped slider 33, locking the relative position of the adjacent frame 1, and eliminating the splice gap; at the corner of the column mold, tighten the large nut washer 14 on the first screw 12, lock the L-shaped stop block 13, and close the corner gap of the column mold.

The first reinforcing screw (214) and the second reinforcing screw (221) As the first gear (237) and the second gear (247) rotate synchronously, the first threaded cylinder (215) and the second threaded cylinder (222) slide synchronously along the inner wall of the reinforcing sleeve (212), and simultaneously press against the two side frames (1) to uniformly correct the verticality of the frame (1); when individual adjustment is required: press the first push plate (233) to compress the first spring (235), so that the first positioning rod (234) disengages from the first slot (2371), and disconnects the first reinforcing screw The rod (214) is linked with the transmission wheel (253), and only the second reinforcing screw (221) is adjusted with the transmission wheel (253); or the second push plate (243) is pressed to compress the second spring (245), the second positioning rod (244) is disengaged from the second slot (2471), the transmission linkage between the second reinforcing screw (221) and the second gear (247) is disconnected, and the first reinforcing screw (214) is controlled to push the frame (1) separately, and the offset of the frame (1) on one side is specifically corrected; S6. Demolding, Transfer and Storage: After the column concrete reaches the specified demolding strength, reverse the upper operation to dismantle the frame (1); first rotate the block (256) to loosen the worm gear (255) transmission, press the first push plate (233) and the second push plate (243) to release the linkage, rotate the first reinforcing screw (214) and the second reinforcing screw (221) in the reverse direction, retract the first reinforcing rod (217) and the second reinforcing rod (224), pull out the first rod body (6) and the second rod body (7) to loosen the reinforcing rod length limit, pull out the insert rod (42) to disengage from the stop block (41), slide the U-shaped slider (33) to loosen the adjacent frame (1) clamping structure; unscrew the large nut washer (14), remove the L-shaped abutment (13), disassemble multiple sets of frames (1), disassemble all components, clean the concrete residue on each component, classify and store them for the next turnover.
