Description

Technical Field

[0001] The invention relates to the technical field of climbing formwork devices, and in particular to a hydraulic climbing formwork device for high bridge piers. Background Art

[0002] The hydraulic climbing formwork device for high bridge piers is an advanced construction equipment. It drives the climbing mechanism through the hydraulic system to make the formwork system gradually rise along the pier, thereby completing the construction of the pier. The device mainly includes the formwork system, hydraulic system, climbing mechanism and control system. It has the advantages of improving construction efficiency, reducing labor costs, ensuring construction quality and safety, and is widely used in the construction of high bridge piers. During construction, the formwork system is fixed at the bottom of the pier, and the hydraulic system drives the climbing mechanism to gradually rise the formwork system. The control system ensures the stability and accuracy of the formwork system. When the formwork system reaches the designated position, concrete pouring and curing are carried out. After the concrete solidifies, the climbing mechanism is driven by the hydraulic system again to make the formwork system continue to rise, and the above process is repeated until the pier construction is completed.

[0003] The formwork system includes steel formwork, which is made of high-strength material to ensure rigidity and surface flatness. Steel formwork has high deformation resistance, that is, the characteristic of "not easy to deform". When demoulding, the demoulding resistance is closely related to the contact area between the formwork and concrete. Reducing the instantaneous contact area by gradually uncovering the side of the formwork is an effective way to reduce the demoulding resistance, but this method is not suitable for steel formwork with high deformation resistance, resulting in greater resistance during demoulding, which will increase the difficulty of demoulding and is not conducive to improving the efficiency of demoulding.

[0004] If thinner and bendable steel plates are used as steel formwork, the above problems can be avoided compared to using hard steel plates with strong deformation resistance as formwork, but there will be the following defects: Formwork deformation: Thinner steel plates are prone to deformation under the pressure and self-weight of concrete pouring, resulting in unstable shape and size of the formwork, affecting the geometric accuracy and surface quality of the pier. After the formwork is deformed, additional correction and adjustment work may be required, increasing construction time and cost.

[0005] Deterioration of concrete surface quality: Deformation of the formwork will cause wavy and uneven defects on the concrete surface, affecting the appearance quality and performance of the pier. Summary of the invention

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figure 1 , Figure 2 As shown, the hydraulic climbing formwork device for high bridge piers proposed by the present invention includes a wall-attached support 1, a guide rail 101 installed on the wall-attached support 1, a bearing platform 102 connected to the wall-attached support 1 and the guide rail 101, and a climbing system 103 installed on the bearing platform 102. A formwork support platform 104 is fixedly installed on the bearing platform 102. The wall-attached support 1 serves as the foundation of the device, the guide rail 101 serves as a track for the device to move, the bearing platform 102 serves as a safe working space, and the climbing system 103 serves as a power source for driving the guide rail 101 or the bearing platform 102 in the device to move. Through the close linkage of mechanical transmission and intelligent control, high piers can be constructed quickly and the safety of construction can be improved. The above structures are all existing technologies and will not be described here.

[0022] like Figures 3 to 6As shown, the hydraulic climbing formwork device also includes a formwork system 3 fixedly installed on the formwork support platform 104, and the formwork system 3 includes a plurality of elastic thin steel plates 301, and the thin steel plates 301 can undergo a certain range of deformation, so that when demolding, the thin steel plates 301 can be gradually bent inward from one side, that is, the thin steel plates 301 can be gradually "uncovered" outward from one side. At this time, the thin steel plates 301 gradually separate from the wall 2 in a "line contact" manner, thereby effectively reducing the resistance encountered during demolding, thereby effectively reducing the resistance to demolding, and increasing the speed of demolding. A traction mechanism is fixedly installed on the formwork support platform 104, and the traction mechanism drives both sides of the thin steel plates 301 to bend and separate from the wall 2. Under the action of the traction mechanism, the thin steel plates 301 are gradually separated from the wall, providing traction for the thin steel plates 301 to separate from the wall.

[0023] Furthermore, the traction mechanism includes a pull rod 5 rotatably mounted on both sides of the thin steel plate 301, a plurality of guide rails 501 corresponding to the thin steel plate 301 are fixedly mounted on the template support platform 104, and sliders 502 are slidably mounted on both sides of the guide rails 501. The sliders 502 are slidably connected to the pull rod 5. Under the action of the sliders 502 and the guide rails 501, the pull rod 5 can be moved in two directions. When the thin steel plate 301 is demoulded, the thin steel plate 301 will rotate relative to the connection with the pull rod 5, and the two ends will shrink inward, which will drive the pull rod 5 to move on the guide rails 501 and the sliders 502. The pull rod 5 is rotatably mounted on two rotating shafts 504, and a plurality of winding disks 505 corresponding to the traction members 503 are fixedly mounted on the rotating shafts 504. The winding disks 505 are fixedly connected to one end of the traction member 503. When the winding disks 505 rotate, the traction member 503 will be wound around. At this time, the pulled traction member 503 will apply a pulling force to the pull rod 5, thereby causing the pull rod 5 to pull the thin steel plate 301, so that the thin steel plate 301 can be demoulded.

[0024] Among them, a driving disk 506 is fixedly installed on the rotating shaft 504, and a plurality of sockets 507 are provided on the driving disk 506, in which a lever 508 is inserted. By selecting the socket 507 at a suitable position and inserting the lever 508, the lever principle can be used to achieve a labor-saving effect, thereby driving the rotating shaft 504 to rotate, and then driving the winding disk 505 above to rotate. Gears 509 that mesh with each other are fixedly installed on the two rotating shafts 504. The gears 509 can make the two rotating shafts 504 rotate synchronously in opposite directions, so that both sides of the thin steel plate 301 can be demoulded at the same time.

[0025] like Figures 7 to 10As shown, the present embodiment further includes a plurality of groups of curvature control components 4 installed on the thin steel plate 301, and the curvature control components 4 control the maximum curvature of the thin steel plate 301 when being bent. Since the thin steel plate 301 is prone to bend when subjected to external force, local demolding may be difficult during demolding. At this time, when tension is continuously applied to both sides of the thin steel plate 301, the thin steel plate 301 will continue to bend, causing the thin steel plate 301 to be excessively bent and plastically deformed, that is, the thin steel plate 301 cannot recover under the action of its own elastic force, which will cause the thin steel plate 301 to be scrapped, reduce the service life of the thin steel plate 301, and be unfavorable for the recycling of the thin steel plate 301.

[0026] Wherein, the curvature control component 4 includes two connecting blocks 401 fixedly mounted on the thin steel plate 301, a pressure rod 402 is rotatably mounted on one of the connecting blocks 401, a sleeve 403 is rotatably mounted on the other pressure rod 402, the sleeve 403 is slidably connected with the pressure rod 402 and sealed by a sealing ring 404, a storage box 405 is fixedly mounted on one of the connecting blocks 401, a sealing plate 406 is slidably mounted in the storage box 405, a spring 407 is fixedly mounted between the sealing plate 406 and the storage box 405, the storage box 405 and the sleeve 403 are connected through a pipe 408, the pipe 408, the sleeve 403 and one side of the storage box 405 are filled with hydraulic medium, the hydraulic medium is a liquid that cannot be compressed in the working environment, when demoulding, the thin steel plate 301 will It will bend inwards. At this time, if two points are selected on the thin steel plate 301, the straight-line distance between the two points will be shortened. Accordingly, when the thin steel plate 301 is demoulded, the distance between the two connecting blocks 401 will be shortened. At this time, the pressure rod 402 will drive the sealing ring 404 to move in the sliding sleeve 403, which will squeeze the hydraulic medium inside the sliding sleeve 403 into the storage box 405 through the pipeline 408. When the storage box 405 can no longer accommodate more hydraulic medium, the pressure rod 402 can no longer slide into the sliding sleeve 403. At this time, the distance between the two connecting blocks 401 will no longer be shortened, and the thin steel plate 301 connected to the connecting block 401 cannot shrink, thereby preventing the thin steel plate 301 from being damaged due to excessive bending.

[0027] Furthermore, the storage box 405 is provided with a curvature limiting mechanism for adjusting the effective capacity in the storage box 405. The maximum curvature of different areas of the thin steel plate 301 can be reasonably set according to the position and requirements of the thin steel plate 301. The curvature limiting mechanism includes a limit rod 409 slidably and rotatably installed inside the storage box 405. The limit rod 409 and the storage box 405 are fixedly installed with a support ring 410 with an internal thread. One end of the limit rod 409 is provided with an external thread and is threadedly connected to the support ring 410. When the thin steel plate 301 contracts, the hydraulic medium inside the sleeve 403 enters the storage box 405, which in turn drives the sealing plate 406 to move and compresses the spring 407. When the sealing plate 406 contacts the limit rod 409, the sealing plate 406 cannot continue to move, and then the initial distance between the limit rod 409 and the sealing plate 406 is adjusted by rotating the limit rod 409, thereby adjusting the maximum curvature of the thin steel plate 301.

[0028] It is worth noting that by rotating the limit rod 409, the sealing plate 406 can be pushed to move, so that the hydraulic medium inside the storage box 405 can enter the inside of the sliding sleeve 403, which will drive the bent thin steel plate 301 to stretch, thereby resetting the thin steel plate 301 and making it straight. After the limit rod 409 drives the sealing plate 406 to move to the extreme position, the thin steel plate 301 is just in a straight state, and then the thin steel plate 301 in the straight state can be fixed to prevent the thin steel plate 301 from bending, thereby facilitating mold closing.

[0029] like Figures 14 to 16 As shown, the hydraulic climbing formwork device in this embodiment also includes a pressing mechanism 7, which is installed on the formwork support platform 104. The pressing mechanism 7 applies pressure to the thin steel plate 301 to fasten the thin steel plate 301 to the wall 2. The pressing mechanism 7 includes a guide plate 701 fixedly installed on the formwork support platform 104, and a slide plate 702 is slidably installed in the guide plate 701. Support columns 703 and reinforcing rods 704 are rotatably installed at both ends of the slide plate 702. The reinforcing rod 704 is rotatably connected to the support column 703. A support beam 705 is fixedly installed on the support column 703. A plurality of pressure-applying members corresponding to the thin steel plates 301 are installed on the support beam 705. A driving component for driving the slide plate 702 to move is installed in the guide plate 701. Under the action of the driving component, the pressure-applying member is pressed against the thin steel plate 301, thereby pressurizing and fixing the thin steel plate 301.

[0030] The pressure member includes a connecting member 706 fixedly mounted on the supporting beam 705 , and a pressure beam 707 is fixedly mounted on the connecting member 706 . The pressure beam 707 will lean against the thin steel plate 301 , thereby evenly fixing the thin steel plate 301 .

[0031] Furthermore, the driving assembly includes a rack 708 fixedly mounted on the slide plate 702, a driving gear 709 rotatably mounted in the guide plate 701 and meshing with the rack 708, a transmission shaft 710 is fixedly mounted on the driving gear 709, the transmission shaft 710 passes through one side of the guide plate 701 and extends to the outside of the guide plate 701, and one end of the transmission shaft 710 is detachably connected to a ratchet wrench 711, which can drive the transmission shaft 710 to rotate. The rotating transmission shaft 710 will drive the rack 708 to move through the driving gear 709, and then drive the pressure beam 707 to move toward or away from the thin steel plate 301 through the slide plate 702.

[0032] like Figures 11 to 13 As shown, in this embodiment, a tensioning module is installed on the thin steel plate 301, and the tensioning module tensions the thin steel plate 301 to shield the bending effect of the thin steel plate 301 when it is affected by external force. When the two sides of the thin steel plate 301 are subjected to outward pulling force, the thin steel plate 301 will be in a tensioned state. At this time, the thin steel plate 301 will be unable to bend, which is convenient for cleaning and testing the surface of the thin steel plate 301. The tensioning module includes a guide rod 6 fixedly installed in the middle of the thin steel plate 301, and a connecting seat 601 is slidably installed on the guide rod 6. Connecting rods 602 are rotatably installed at both ends of the thin steel plate 301, and the other end of the connecting rod 602 is rotatably connected to the connecting seat 601. When pressure is applied to the connecting seat 601, the two sides of the thin steel plate 301 will be tensioned outwards under the action of the connecting rods 602 on both sides to prevent the thin steel plate 301 from bending, avoid the instability of the shape of the template, and prevent the reduction of the geometric accuracy and surface quality of the pier.

[0033] Furthermore, both upper and lower sides of the connecting seat 601 are equipped with limiting components for limiting the position of the connecting seat 601. When the position of the connecting seat 601 is limited, the connecting rods 602 on both sides will also be limited, which can effectively prevent the thin steel plate 301 from bending. The limiting component includes a limiting rod 603 fixedly installed on the connecting seat 601, a mounting plate 604 is fixedly installed on one end of the guide rod 6, a limiting cylinder 605 is fixedly installed on the mounting plate 604, a plug 606 is fixedly installed on the limiting rod 603, which is sealed and slidably connected to the limiting cylinder 605, and both ends of the limiting cylinder 605 are connected through a connecting pipe 607, and a valve 608 is fixedly installed on the connecting pipe 607. The door 608, the connecting pipe 607 and the limiting cylinder 605 are all filled with hydraulic medium, and the hydraulic medium is a liquid that cannot be compressed under the working environment. When the connecting seat 601 moves, it will drive the plug 606 to move inside the limiting cylinder 605. At this time, the hydraulic medium inside the limiting cylinder 605 will circulate on both sides of the limiting cylinder 605 through the connecting pipe 607. At this time, the plug 606 and the limiting rod 603 can move freely. When the valve 608 is closed, the hydraulic media on both sides of the limiting cylinder 605 will not be able to circulate with each other, thereby making the limiting rod 603 unable to move, that is, the connecting seat 601 cannot move, thereby making the thin steel plate 301 unable to bend.

[0034] In this embodiment, the thin steel plate 301 can be deformed within a certain range, so that when demoulding, the thin steel plate 301 can be gradually bent inward from one side, that is, the thin steel plate 301 can be gradually "uncovered" outward from one side. At this time, the thin steel plate 301 gradually separates from the wall 2 in a "line contact" manner, thereby effectively reducing the resistance encountered during demoulding, thereby effectively reducing the resistance to demoulding, and increasing the speed of demoulding; When demoulding is performed, the distance between the two connecting blocks 401 is shortened. At this time, the pressure rod 402 will drive the sealing ring 404 to move in the sleeve 403, which will squeeze the hydraulic medium inside the sleeve 403 into the storage box 405 through the pipe 408. When the storage box 405 can no longer accommodate more hydraulic medium, the pressure rod 402 cannot continue to slide into the sleeve 403. At this time, the distance between the two connecting blocks 401 will not be able to be shortened any more, and the thin steel plate 301 connected to the connecting block 401 cannot be contracted, thereby preventing the thin steel plate 301 from excessive bending and damage.

[0035] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
