Description

Technical Field

[0001] This invention relates to the field of pier formwork technology, and in particular to an adaptive formwork structure for irregularly shaped high pier sections. Background Technology

[0002] In actual construction of irregularly shaped high piers, self-climbing formwork systems are widely used. These systems support the formwork, ensuring the quality of subsequent pouring. Through their automated control structure, they can drive formwork closing and dismantling operations, improving pouring efficiency. During the pouring of irregularly shaped high piers, only the formwork strips on both sides of the face form need to be replaced layer by layer as the segment rises to adapt to the variable cross-section pouring. Currently, adaptive formwork structures for irregularly shaped high piers typically only use steel truss structures, which are inconvenient for actual formwork support. For fastening tie rods, especially for pier wall surfaces, traditional tie rods require cutting before subsequent hole filling and other operations, resulting in low operational efficiency. At the same time, traditional truss structures make it difficult to guide workers on the proper order of formwork assembly and disassembly. Workers usually have to figure out the correct order of operation for formwork and tie rods themselves, which is not conducive to controlling the formwork construction process. Fastening tie rods directly before the formwork is closed can easily cause abnormal deformation of the formwork. Disassembling the formwork without first removing the tie rods can cause stress concentration at the tie rods, resulting in problems such as hidden cracks and chipping. Summary of the Invention

[0008] Furthermore, the unidirectional limiting component includes: a limiting mounting block, a first insert block, and a positioning tooth.

[0009] Furthermore, the unidirectional limiting component also includes: a first electromagnet and a first spring, wherein the first electromagnet is fixedly mounted on the limiting mounting block; the first electromagnet is aligned with the first insertion block; the first spring is fixedly mounted on the first insertion block, and the end of the first spring is fixedly mounted on the first electromagnet; the first spring is located inside the limiting mounting block; the two rows of bolts are electrically connected to the two rows of first electromagnets.

[0010] Furthermore, the pull rod connector includes: a mounting post, a positioning groove, and a threaded connecting post. The mounting post is slidably inserted into the limiting mounting block.

[0014] This invention provides an adaptive formwork structure with irregularly shaped high pier cross section, which has the following beneficial effects:

[0015] This invention employs a one-way limiting component, which can prevent interference with normal rotation and separation of the tie rods. In conjunction with the control of the bolt switch, it can prompt workers to complete the mold closing process before connecting the tie rods, thus improving the standardization of the engineering process. Especially in the early stage of template fine-tuning, the tie rods are fixed components rather than positioning components. If the tie rods are tightened prematurely, it will directly interfere with subsequent template adjustments and may even cause template deformation.

[0016] In addition, the use of demolding locking components in conjunction with tie rod connectors can further guide the staff in the demolding operation sequence. It can automatically lock the push screw after the mold is closed and the tie rod connection is tightened, ensuring that the staff prioritizes disassembling the threaded connecting column before disassembling the mold closing bolts, thus reducing the risk of concrete chipping and hidden cracks in the pier column.

[0017] In addition, the use of tie rod connectors allows for the connection of tie rods within the cast-in-place surface. After the threaded connecting column is removed, the end of the tie rod remains within the cast-in-place surface. Workers only need to seal the hole formed by the threaded connecting column on the cast-in-place surface, eliminating the need to cut off the exposed tie rod, thus improving the efficiency of pier construction and reducing operational difficulty.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figures 1 to 11 :

[0037] This invention proposes an adaptive formwork structure for irregularly shaped high pier sections, including a formwork moving device 1, with formwork strip reinforcement members 2 installed on both sides of the formwork moving device 1; the two formwork strip reinforcement members 2 are symmetrically arranged; two rows of one-way limiting members 3 are installed on the formwork moving device 1; tie rod connectors 4 are installed on the two rows of one-way limiting members 3 respectively; the tie rod connectors 4 are used to connect tie rods; demolding locking members 5 are installed on the two formwork strip reinforcement members 2 respectively; the formwork moving device 1 includes: a truss 101 and a screw control switch 1011, two trusses 101 are provided, and screw control switches 1011 are fixedly installed on the two trusses 101 respectively; the pressing end of the screw control switch 1011 is aligned with the corresponding tie rod connector 4.

[0038] In this embodiment, the mold-moving device 1 further includes: a vertical beam 102, a rotating shaft plate 1021, a face mold 103, mold strips 104, a limiting insert block 1041, and a mold-closing bolt 105. Two vertical beams 102 are provided, and the two vertical beams 102 are fixedly installed on two trusses 101 by bolts. Two rotating shaft plates 1021 are fixedly installed on each of the two vertical beams 102. Shaft holes are provided at the bottom of each of the two vertical beams 102. Face molds 103 are fixedly installed on the two trusses 101 by bolts. Mold strips 104 are fixedly installed on both sides of the face mold 103 by bolts. Limiting blocks 1041 are fixedly installed on each of the two mold strips 104, and the two limiting blocks 1041 are respectively inserted into the two sides of the face mold 103; a row of mold closing bolts 105 are respectively inserted into each of the two mold strips 104, and a nut is provided on each of the row of mold closing bolts 105; the mold strip reinforcement component 2 includes: a reinforcing mounting plate 201, a sliding shaft 202 and a push screw 203, the reinforcing mounting plate 201 is fixedly installed on the two trusses 101 by bolts; two sliding shafts 202 are slidably installed on the reinforcing mounting plate 201; a push screw is threadedly connected to the reinforcing mounting plate 201. The rod 203 has a hexagonal insertion hole at its end; a groove is formed on the push screw 203; the mold strip reinforcement 2 also includes: a push plate 204, bolt switches 205, and limit blocks 206. The push plate 204 is fixedly installed on the two sliding shafts 202; a row of bolt switches 205 is fixedly installed on the side of the push plate 204, and the row of bolt switches 205 is inclined; a row of limit blocks 206 is fixedly installed on the inner side of the push plate 204 by bolts; the row of limit blocks 206 abuts against the mold strip 104, and the outer side of the limit blocks 206... The side abuts against the inner edge of the formwork strip 104; the bolt switch 205 abuts against the end of the corresponding mold closing bolt 105; two telescopically adjustable formwork strip reinforcement parts 2 are used, which can easily adapt to formwork strips 104 of different widths. As the pier column pouring segment rises, when gradually replacing with narrower formwork strips 104, adjustments can still be made to adapt. It can also help reinforce the formwork strip 104. The adjustment of this structure is simple and quick. It can be quickly adjusted by pushing the screw 203. The formwork strip 104 is slidably inserted into the face mold 103, making it even simpler to replace the formwork strip 104.

[0039] In this embodiment, the one-way limiting member 3 includes: a limiting mounting block 301, a first insert block 302, and a positioning tooth 3021. The limiting mounting block 301 is fixedly mounted on the truss 101. The first insert block 302 is inserted into the limiting mounting block 301, and the end of the first insert block 302 is provided with a positioning tooth 3021. A through hole is provided in the middle of the limiting mounting block 301. The positioning tooth 3021 is located in the through hole in the middle of the limiting mounting block 301. The one-way limiting member 3 also includes: a first electromagnet 303 and a first spring 304. A first electromagnet 303 is fixedly installed on the first plug block 302; the first electromagnet 303 is aligned with the first plug block 302; a first spring 304 is fixedly installed on the first plug block 302, and the end of the first spring 304 is fixedly installed on the first electromagnet 303; the first spring 304 is located inside the limiting mounting block 301; two rows of bolt switches 205 are electrically connected to the two rows of first electromagnets 303; the pull rod connector 4 includes: a mounting post 401, a positioning groove 4011 and a threaded connecting post 402, the mounting post 401 is slidably inserted into the limiting mounting block 301; A positioning groove 4011 is formed on the mounting post 401; positioning teeth 3021 are inserted into the positioning groove 4011; a threaded connecting post 402 is fixedly installed at the end of the mounting post 401; the threaded connecting post 402 passes through the face mold 103; the end of the mounting post 401 abuts against the side wall of the face mold 103; the pull rod connector 4 also includes: a return spring 403, a return spring 403 is sleeved on the mounting post 401, and the end of the return spring 403 is fixedly connected to the mounting post 401; the other end of the return spring 403 abuts against the limiting mounting block 301. The use of tie rod connector 4 facilitates quick connection of the tie rod. At the same time, the threaded connecting post 402 can be inserted into the mold 103. The threaded hole end of the threaded connecting post 402 is within the forming surface of the mold 103. This structural feature makes it easy to connect the tie rod within the casting forming surface. After the threaded connecting post 402 is removed, the end of the tie rod is within the casting forming surface. The staff only needs to seal the hole formed by the threaded connecting post 402 on the forming surface. There is no need to cut off the exposed tie rod.

[0040] The use of one-way limiting component 3 allows for separation of the tie rods without affecting normal rotation. Combined with the control of bolt switch 205, it prompts workers to complete the formwork closing process before connecting the tie rods, improving the standardization of the project workflow. This is especially important in the early stages of formwork fine-tuning, where the tie rods are fixed components rather than positioning components. Premature tightening of the tie rods can directly interfere with subsequent formwork adjustments and even cause formwork deformation. This structure is simple to control and can prompt workers by locking the installation column 401, optimizing the formwork construction process and reducing the rework rate of formwork installation.

[0041] In Example 2, based on Example 1, the demolding locking component 5 includes: a second electromagnet 501, a second insert block 502, and a locking protrusion 5021. The second electromagnet 501 is fixedly mounted on the reinforcing mounting plate 201; the second insert block 502 is slidably inserted into the reinforcing mounting plate 201, and the locking protrusion 5021 is fixedly mounted on the second insert block 502, and the locking protrusion 5021 is used to insert into the groove on the push screw 203; the second electromagnet 501 is aligned with the second insert block 502; the two rows of screw control switches 1011 are electrically connected to the two second electromagnets 501; the demolding locking component 5 also includes: a second spring 503, which is located inside the reinforcing mounting plate 201; one end of the second spring 503 is fixedly connected to the second electromagnet 501, and the other end of the second spring 503 is fixedly connected to the second insert block 502; the demolding locking component 5 is used in conjunction with the pull rod connector 4. This system can further guide workers on the demolding sequence. It automatically locks the push screw 203 after the mold is closed and the tie rods are tightened. This ensures that workers prioritize disassembling the threaded connecting column 402 before removing the mold closing bolts 105, improving the standardization of the construction process, reducing the risk of demolding damage, and preventing excessive stress concentration on the tie rods and threaded connecting columns 402 due to the formwork's weight. This would directly increase the risk of concrete spalling and microcracks around the threaded connecting columns 402. Prioritizing the disassembly of the tie rods ensures that the formwork stress is primarily borne by the self-climbing formwork system, simplifying structural control. Locking the push screw 203 before demolding also helps prevent large-scale loosening of the push screw 203, which could affect the support quality of the formwork strip 104.

[0042] The working principle of this embodiment is as follows: Before the pouring construction, the four parts of this structure are used as a combined mold. First, the through hole at the bottom of the vertical beam 102 is rotated and installed on the self-climbing formwork translation hinge seat through the shaft pin. Then, the shaft plate 1021 is inserted through the shaft pin and rotated and installed on the flipping hinge seat on the output shaft of the flipping hydraulic cylinder. The formwork strip 104 can be replaced according to the current pouring construction segment height. The new formwork strip 104 is directly inserted into both sides of the face mold 103 and then fastened with bolts. In the initial state, the threaded connecting column 402 is not connected to the tie rod. At this time, under the compression of the return spring 403, each mounting column 401 presses the screw control switch 1011. At this time, the second electromagnet 501 is energized, the second insert block 502 is magnetically attracted and retracted, and the push screw 203 can rotate normally. Then, the self-climbing formwork drive structure and the flipping drive structure control the movement. The face mold 103 is brought close to the pier column, and a fine-tuning operation is performed to keep the four mold strips 104 closed. The mold closing bolts 105 are inserted between adjacent mold strips 104 to secure the mold. Then, the push screw 203 can be rotated to drive the push plate 204 to move outward. The limit block 206 will also be moved to abut against the inner edge of the mold strip 104 to assist in supporting the mold strip 104. At the same time, the bolt switch 205 will also be moved to press against the end of the mold closing bolt 105. When all the mold closing bolts 105 are pressed, the first electromagnet 303 can be activated to attract the first insert block 302 to move backward and compress the first spring 304. At this time, the positioning tooth 3021 will be pulled out from the positioning groove 4011. Only then can the mounting column 401 be rotated normally, driving the threaded connection column 402 to connect the threaded tie rod reserved in the thread. This ensures that the mold is closed first, and then the tie rod installation operation is performed.

[0043] After each threaded connecting post 402 is tightened to the pull screw, each return spring 403 is pressed, and each mounting post 401 will not press the screw control switch 1011. At this time, the screw control switch 1011 will control the second electromagnet 501 to quickly de-energize. At this time, the second insert block 502, under the elastic compression of the second spring 503, will push the locking protrusion 5021 against the outside of the push screw 203. If demolding is required after the concrete has cured, each threaded connecting post 402 must be rotated and disassembled first. Under the compression of the return spring 403, each mounting post 401 will press the screw control switch 1011. The second electromagnet 501 will be energized and magnetically attract the second insert block 502, causing the locking protrusion 5021 to move away from the push screw 203. Only then can the push screw 203 rotate normally, driving the push plate 204 to retract and no longer block the mold closing bolt 105. The mold closing bolt 105 can then be disassembled.

[0044] When the mold strip 104 is not closed and the mold bolt 105 is installed, the bolt switches 205 cannot be pressed at the same time. The first electromagnet 303 is in the de-energized state. Under the compression of the first spring 304, the positioning teeth 3021 on the first insert block 302 can be kept against the positioning groove 4011. If the mounting column 401 is rotated directly to drive the threaded connecting column 402 to connect with the tie rod, the positioning teeth 3021 will be directly stuck in the positioning groove 4011 when rotating. This prompts the staff to close and tighten the mold before installing and connecting the tie rod.

[0045] Similarly, if during mold disassembly, the threaded connecting posts 402 are not yet disconnected from the tie rod, the screw control switch 1011 is not pressed by the mounting post 401, and the second electromagnet 501 is de-energized. At this time, the second insert block 502, under the elastic compression of the second spring 503, will push the locking protrusion 5021 against the outside of the push screw 203. Once you want to rotate the push screw 203 to remove the mold clamping bolt 105, the locking protrusion 5021 will quickly insert into the groove on the push screw 203 to lock.
