Description

Technical Field

[0001] This application relates to the field of concrete column fabrication technology, specifically the design of a reinforced formwork structure for irregular frame columns. Background Technology

[0002] In public buildings, school stadiums, and landmark buildings, irregularly shaped frame columns (such as L-shaped, T-shaped, inverted L-shaped, and curved columns) are increasingly used to meet the requirements of architectural aesthetics and interior space utilization. Irregularly shaped frame columns differ from traditional rectangular cross-section columns; their cross-sectional geometry is irregular, especially those with curved surfaces. While pursuing architectural aesthetics, this also presents significant challenges to construction.

[0003] Due to the complex stress distribution of irregularly shaped columns, the lateral pressure generated during concrete pouring is extremely uneven, especially in the curved surface area of ​​the formwork. The lateral pressure generates tangential and radial components along the curved surface, causing the formwork to bear multidimensional loads in this area. In practice, construction workers typically use steel back braces in conjunction with tie bolts to reinforce the formwork. However, for the curved surface of irregularly shaped columns, conventional straight steel back braces cannot effectively conform to the curvature of the curved surface. Even when using on-site bent curved steel bars as back braces, their stiffness is often insufficient, and the lateral pressure increases closer to the bottom of the concrete column, making the curved surface at the bottom of the formwork more susceptible to deformation. When the stiffness of the back braces is insufficient to restrain the deformation of the formwork, the curved surface at the bottom of the formwork will bulge locally under the lateral pressure of the concrete, causing the column cross-sectional dimensions to deviate from the design requirements. Rework and repair significantly increase construction costs and slow down the construction progress. Summary of the Invention

[0004] How to achieve precise and stable reinforcement of the arc surface of irregularly shaped column formwork through structural innovation, reduce its deformation under concrete lateral pressure, and thus effectively control the deviation of the frame column cross-section dimensions, is a technical problem that urgently needs to be solved in the field of irregularly shaped concrete structure construction. In order to effectively control the deviation of the cross-section dimensions of irregularly shaped frame columns, this application proposes the following technical solution.

[0005] A formwork reinforcement structure for irregularly shaped frame columns includes a formwork with a circular arc surface, an arc-shaped back rib, a left sliding bar, a right sliding bar, a left abutment, a middle abutment, and a right abutment.

[0006] The arc-back ribs tighten the left, middle, and right ribs on the arc surface.

[0007] The left and right slide bars are slidably mounted on the outside of the arc-shaped back rib. The arc-shaped back rib has a left protrusion, a middle protrusion, and a right protrusion, which are opposite to the left, middle, and right rib plates, respectively. The left protrusion passes through the left slide bar and connects to the right abutment. The right protrusion passes through the right slide bar and connects to the right abutment. The two ends of the left slide bar abut against the left end of the arc-shaped back rib and the left side of the middle protrusion; the two ends of the right slide bar abut against the right end of the arc-shaped back rib and the right side of the middle protrusion; the middle abutment is pressed tightly against the left and right slide bars.

[0008] If the left rib plate has a tendency to bulge outward, the left protrusion will bulge outward and drive the left slide bar to press against the left end of the arc back rib, and the left abutment will press the left rib plate inward.

[0009] If the middle rib plate has a tendency to bulge outward, the middle protrusion will bulge outward and drive the left and right slide bars to press against the two ends of the arc back rib, while the middle abutment will press the middle rib plate inward.

[0010] If the right rib plate has a tendency to bulge outward, the right protrusion will bulge outward and drive the right slide bar to press against the right end of the arc back rib, and the right abutment will press the right rib plate inward.

[0011] By adopting the above technical solution, the local outward deformation of the three ribs is transformed into the sliding motion of the slide bar, which presses against one or both ends of the arc back rib to enhance the anti-deformation effect. At the same time, it can also drive the corresponding abutment in the deformation area to press against the rib, further enhancing the anti-deformation effect. This achieves precise self-response anti-deformation, thereby effectively controlling the dimensional deviation of the arc surface and reducing the defect rate of the cross-sectional dimensions.

[0012] Preferably, both sides of the central protrusion are inclined surfaces. The right end of the left slider is inclined, abutting against one inclined surface of the central protrusion. The left slider also has a left through hole in its middle, the left wall of which is inclined, and the left protrusion abuts against the inclined left wall of the left through hole, without contacting the right wall of the left through hole. One end of the left abutment passes through the left through hole and connects to the left protrusion. The left end of the right slider is inclined, abutting against the other inclined surface of the central protrusion. The right slider also has a right through hole in its middle, the right wall of which is inclined, and the right protrusion abuts against the inclined right wall of the right through hole, without contacting the left wall of the right through hole. One end of the right abutment passes through the right through hole and connects to the right protrusion.

[0013] By adopting the above technical solution, the change from one direction of motion to another is achieved through the inclined surface abutting the transmission structure. The left protrusion only abuts against the inclined surface of the left wall of the left through hole and does not contact the right wall, so that when the middle protrusion moves, the left slider will not push the left protrusion, and the right slider will not push the right protrusion, thus preventing motion interference.

[0014] Preferably, the left abutment and the right abutment are symmetrically arranged. The left abutment includes a left extension rod, an upper left vertical rod, an upper left seat, an upper left horizontal rod, an upper left plate, a lower left vertical rod, a lower left seat, a lower left horizontal rod, and a lower left plate. One end of the left extension rod is connected to the left protrusion, and the other end is hinged to the upper left vertical rod and the lower left vertical rod. The upper left vertical rod passes through the upper left seat and can rotate and move axially on the upper left seat. The lower left vertical rod passes through the lower left seat and can rotate and move axially on the lower left seat. The upper end of the upper left vertical rod is hinged to one end of the upper left horizontal rod. The other end of the upper left horizontal rod is connected to the upper left plate. The lower end of the lower left vertical rod is hinged to one end of the lower left horizontal rod. The other end of the lower left horizontal rod is connected to the upper left plate. If the left rib plate has a tendency to bulge outward, the left protrusion drives the left extension rod to move outward, causing the upper left vertical rod and the lower left vertical rod to rotate and move along their respective axes, thereby driving the upper left horizontal rod and the lower left horizontal rod to translate inward, so that the upper left plate and the lower left plate abut against the left rib plate on the upper and lower sides of the arc back rib.

[0015] By adopting the above technical solution, when the left rib plate deforms, the left protrusion moves outward, which can simultaneously drive the two plates to press the left rib plates on the upper and lower sides of the arc back rib, strengthen the longitudinal reinforcement effect, and significantly enhance the lateral pressure resistance of the arc surface.

[0016] Preferably, the middle abutment includes a left inclined block, a left shaft, a left rotating rod, a left crossbar, a left rotating seat, a middle rod, a connecting rod, a middle pressure plate, a right rotating seat, a right crossbar, a right rotating rod, a right shaft, and a right inclined block.

[0017] One end of the left shaft is connected to the left inclined block. The inner end of the left rotating rod is hinged to the other end of the left shaft. The left crossbar passes through the left rotating seat and can move and rotate axially on the left rotating seat. One end of the left crossbar is hinged to the outer end of the left rotating rod, and the other end is hinged to the left end of the middle rod.

[0018] The middle section of the central rod is fixed to the connecting rod. The connecting rod connects to the central pressure plate. The two ends of the central pressure plate face the central rib plates on the upper and lower sides of the arc-shaped back rib.

[0019] One end of the right crossbar is hinged to the right end of the middle rod, and the other end is hinged to the outer end of the right rotating rod. The right crossbar passes through the right rotating seat and can move and rotate axially on the right rotating seat. The inner end of the right rotating rod is hinged to one end of the right shaft, and the other end of the right shaft is connected to the right inclined block.

[0020] The outer end of the left-turning rod is closer to the center rod than its inner end. The outer end of the right-turning rod is closer to the center rod than its inner end.

[0021] The left slider abuts against the inclined surface of the left inclined block. The right slider abuts against the inclined surface of the right inclined block.

[0022] By adopting the above technical solution: when the middle rib plate deforms outward, the longitudinal ends of the middle rib plate are reinforced, and the left and right sliding strips are respectively pressed against the ends of the arc back rib, that is, the longitudinal and transverse ends of the middle rib plate are bound and reinforced, which effectively prevents the middle rib plate from deforming outward.

[0023] Preferably, if the central rib plate has a tendency to bulge outward, the central protrusion bulges outward and drives the left and right sliders to move to the left and right ends, drives the left and right inclined blocks to move outward, the left and right shafts move outward along the axial direction, the left and right rotating rods rotate inward, the left and right crossbars rotate synchronously and move along their respective axial directions, pushing the two ends of the central rod to move inward synchronously, so that the central pressure plate presses against the central rib plates on the upper and lower sides of the arc back rib.

[0024] If the left rib plate has a tendency to bulge outward, the left protrusion will bulge outward and drive the left abutment to press against the left rib plate on both sides of the arc back rib. At the same time, the left protrusion will drive the left slide bar to slide to the left, causing the left inclined block to move outward and push the middle rod to move inward, so that the middle pressure plate presses against the middle rib plate on both sides of the arc back rib.

[0025] If the right rib plate has a tendency to bulge outward, the right protrusion will bulge outward and drive the right abutment to press against the right rib plates on the upper and lower sides of the arc back rib. At the same time, the right protrusion will drive the right slide bar to slide to the right, causing the right inclined block to move outward and push the middle rod to move inward, so that the middle pressure plate presses against the middle rib plates on the upper and lower sides of the arc back rib.

[0026] By adopting the above technical solutions: when the left rib plate bulges outward, the left and middle rib plates are reinforced, and the left end of the left sliding bar is pressed against the left end of the arc-back rib, which effectively prevents the left rib plate from bulging outward; when the middle rib plate bulges outward, the longitudinal ends of the middle rib plate are reinforced, and the left and right sliding bars are pressed against the ends of the arc-back rib, which effectively prevents the middle rib plate from bulging outward; when the right rib plate bulges outward, the right and middle rib plates are reinforced, and the right end of the right sliding bar is pressed against the right end of the arc-back rib, which effectively prevents the right rib plate from bulging outward, thereby reducing the defect rate of the concrete column's cross-sectional dimensions.

[0027] Preferably, the intermediate pressure plate includes a U-shaped body, an upper middle plate, and a lower middle plate. The connecting rod connects to the vertical surface of the U-shaped body, and the upper middle plate and the lower middle plate are respectively vertically connected to the two ends of the U-shaped body. The upper middle plate and the lower middle plate are close to the middle rib plates on the upper and lower sides of the arc-shaped back rib.

[0028] By adopting the above technical solution, the two ends of the shaped body are connected to the upper and lower middle plates respectively, so that the middle pressure plate can simultaneously adhere to the middle ribs on both sides of the arc back rib. When the middle ribs have an outward convex tendency, the upper and lower parts are pressed together at the same time, reducing the degree of warping deformation of the middle ribs due to lateral pressure.

[0029] Preferably, the irregular frame column template reinforcement structure further includes a bracket, a left guide sleeve, a right guide sleeve, and a spring. The left guide sleeve wraps around the left shaft, and the right guide sleeve wraps around the right shaft. The left and right guide sleeves are fixed to the bracket. The left inclined block and the left guide sleeve are connected by a spring. The right inclined block and the right guide sleeve are connected by a spring. Both the left and right rotating seats are rotatably mounted on the bracket in their original positions.

[0030] By adopting the above technical solution, the left and right guide sleeves respectively wrap around the left and right shafts, restricting the left and right shafts to only move linearly along the axial direction when subjected to force, thus improving the reliability of the linkage mechanism. The spring between the wedge block and the guide sleeve allows the wedge block to adhere tightly to the left or right slide bar, improving the response efficiency of deformation force application.

[0031] Preferably, the arc surface of the template also has multiple transverse ribs, all perpendicular to the left rib, the middle rib, and the right rib. The transverse ribs, the left rib, the middle rib, and the right rib are arranged at the same height on the outer surface of the template. The left abutment presses against the connection between the left rib and the transverse rib. The middle abutment presses against the connection between the middle rib and the transverse rib. The right abutment presses against the connection between the right rib and the transverse rib.

[0032] By adopting the above technical solution, adding transverse ribs to the longitudinal ribs to form an orthogonal grid significantly improves the overall rigidity and bending resistance of the formwork, reducing deflection during casting. The abutment is relatively stable at the intersection of the longitudinal and transverse ribs, and the pressure extends along both the transverse and longitudinal directions, resulting in good reinforcement.

[0033] Preferably, the two ends of the arc-shaped back rib protrude outwards as stops. The left and right sliding bars respectively abut against the stops at both ends. The irregular frame column template reinforcement structure includes fasteners. The fasteners include tie bolts and straight back ribs. The straight back ribs are located opposite the arc-shaped back ribs. The tie bolts connect the stops and the straight back ribs, so that the straight back ribs and the arc-shaped back ribs clamp the template.

[0034] By adopting the above technical solution, the arc-shaped back rib fits against the convex side of the arc surface, while the straight back rib fits against the flat side of the template. The two are tightened by tie bolts, placing the entire template cross-section under double-sided pressure, significantly improving its resistance to lateral pressure. When the arc surface of the template undergoes outward convex deformation, one or both of the left and right sliding strips move to abut against the stop block, tightening the arc-shaped back rib and strengthening the lateral wrapping effect on the arc surface of the template, adaptively resisting the outward convex deformation of the arc surface.

[0035] In summary, this application provides a reinforcement structure for irregularly shaped frame column formwork. Through the linkage structure design of the formwork, arc-shaped back ribs, fasteners, left sliding bar, right sliding bar, left abutment, middle abutment, and right abutment, it achieves precise perception and adaptive resistance to deformation areas of the formwork's arc surface. When the lateral pressure of the concrete causes the left, middle, or right rib to bulge outwards, the corresponding protrusion drives the sliding bar to slide through the inclined surface, converting the radial displacement into a lateral pushing force. This triggers the corresponding abutment assembly to apply inward pressure, thus resisting the deformation. This achieves high-precision, high-reliability, and low-cost reinforcement of irregularly shaped column formwork, reducing the defect rate of concrete column cross-sectional dimensions.

[0051] A type of irregular frame column formwork reinforcement structure, reference Figure 1 Primarily used for reinforcing template 1, see reference. Figure 2 This is to reduce the deviation in the cross-sectional dimensions of the irregular frame column caused by the deformation of the arc surface 11 of the formwork 1 during the concrete pouring process.

[0052] refer to Figure 3 The reinforcing structure includes template 1, arc back rib 2, fastener 3, left slide bar 4, right slide bar 5, left abutment 6, middle abutment 7, and right abutment 8.

[0053] Template 1 has an arc surface 11, and the outer surface of the arc surface 11 is provided with a longitudinally extending left rib 12, a middle rib 13, and a right rib 14. The left rib 12, the middle rib 13, and the right rib 14 are arranged at intervals along the arc length direction of the arc surface 11, forming three longitudinal reinforcing ribs. The arc back rib 2 is arranged laterally, and its curvature matches the curvature of the arc surface 11, and it is closely attached to the outer side of the left rib 12, the middle rib 13, and the right rib 14. Fasteners 3 tightly press the arc back rib 2 against the three ribs, so that the arc back rib 2 is in close contact with the arc surface 11 of template 1.

[0054] refer to Figure 4 Both the left slider 4 and the right slider 5 are arranged laterally and are arc-shaped, with their curvature matching the curvature of the arc surface 11. The outer surface of the arc-back rib 2 is provided with an arc-shaped groove 201. The left slider 4 and the right slider 5 are respectively connected to a slider, which is slidably installed in the groove 201 of the arc-back rib 2, so that the left slider 4 and the right slider 5 can move relative to the arc-back rib 2 respectively.

[0055] refer to Figure 5 The outer side of the arc-back rib 2 is fixedly provided with a left protrusion 21, a middle protrusion 22 and a right protrusion 23. The positions of the left protrusion 21, the middle protrusion 22 and the right protrusion 23 are respectively aligned with the inner left rib plate 12, the middle rib plate 13 and the right rib plate 14.

[0056] refer to Figure 3 The left end of the left slider 4 and the right end of the right slider 5 abut against the left and right ends of the arc-shaped back rib 2, respectively. For example, the left and right ends of the arc-shaped back rib 2 protrude outward to form a left stop 24 and a right stop 25. The left end of the left slider 4 abuts against the left stop 24, and the right end of the right slider 5 abuts against the right stop 25.

[0057] refer to Figure 2 The fastener 3 includes a tie bolt 31 and a straight back rib 32. The straight back rib 32 is located opposite the arc back rib 2, that is, the straight back rib 32 is attached to the plane side of the template 1 opposite to the arc surface 11. One end of the tie bolt 31 is connected to the left stop block 24 or the right stop block 25, and the other end is connected to the straight back rib 32. Through the tensioning action of the tie bolt 31, the straight back rib 32 and the arc back rib 2 together clamp the template 1. The connection structure between the arc back rib 2 and the fastener 3 can be set in three sets, clamping the template 1 from bottom to top respectively.

[0058] The right end of the left slider 4 and the left end of the right slider 5 abut against the two sides of the central protrusion 22, respectively. For example, both sides of the central protrusion 22 are inclined surfaces. The right end of the left slider 4 is an inclined surface, which abuts against the inclined surface on the left side of the central protrusion 22. The left end of the right slider 5 is an inclined surface, which abuts against the inclined surface on the right side of the central protrusion 22.

[0059] When the arc surface 11 undergoes outward convex deformation, one or both of the left slider 4 and right slider 5 slide and press against the corresponding left stop 24 and / or right stop 25, thereby strengthening the lateral wrapping effect of the arc back rib 2 on the arc surface of the template 1 and adaptively resisting the outward convex deformation of the arc surface of the template. For details on the principle, please refer to the following explanation.

[0060] A left through hole 42 is provided in the middle of the left slider 4. The left wall of the left through hole 42 is inclined. The left protrusion 21 abuts against the inclined left wall of the left through hole 42, and there is a gap between the left protrusion 21 and the right wall of the left through hole 42 so that the two do not contact each other. One end of the left abutment 6 is inserted into the left through hole 42 and fixedly connected to the left protrusion 21.

[0061] The left end of the right slider 5 is a slope, which abuts against the slope on the right side of the central protrusion 22. A right through hole 52 is provided in the middle of the right slider 5. The right wall of the right through hole 52 is a slope, and the right protrusion 23 abuts against the slope of the right wall of the right through hole 52. A gap exists between the right protrusion 23 and the left wall of the right through hole 52, preventing them from contacting each other. One end of the right abutment 8 passes through the right through hole 52 and is fixedly connected to the right protrusion 23.

[0062] The above structure can achieve the conversion of radial displacement to lateral sliding through inclined plane abutment transmission. Specifically, when the template 1 deforms outward, causing the left rib plate 12 to move outward, the left protrusion 21 moves outward with the left rib plate 12. The left protrusion 21 presses against the inclined surface of the left wall of the left through hole 42, thereby pushing the left slide bar 4 to slide to the left. The left end of the left slide bar 4 further presses against the left end of the arc back rib 2, while the right slide bar 5 remains stationary.

[0063] Similarly, when the template 1 deforms outward, causing the right rib plate 14 to move outward, the right protrusion 23 moves outward along with the right rib plate 14. The right protrusion 23 presses against the right wall slope of the right through hole 52, thereby pushing the right slide bar 5 to slide to the right, so that the right end of the right slide bar 5 further presses against the right end of the arc back rib 2. At this time, the left slide bar 4 remains stationary.

[0064] When the middle protrusion 22 moves outward, and pushes the left slider 4 and the right slider 5 to slide to the left and right sides respectively, since the left protrusion 21 does not contact the right wall of the left through hole 42 and the right protrusion 23 does not contact the left wall of the right through hole 52, the left slider 4 will not push the left protrusion 21 through the left through hole 42 and the right slider 5 will not push the right protrusion 23 through the right through hole 52, thereby preventing motion interference. This allows the left protrusion 21 and the left abutment 6 to independently respond to the deformation of the left rib plate 12, and the right protrusion 23 and the right abutment 8 to independently respond to the deformation of the right rib plate 14.

[0065] The working principle of the above structure is as follows.

[0066] During concrete pouring, if the left rib plate 12 of the arc surface 11 tends to bulge outward due to lateral pressure, the left rib plate 12 pushes the left protrusion 21 outward. The outward protrusion of the left protrusion 21 drives the left slide bar 4 to slide to the left, so that the left end of the left slide bar 4 presses against the left end of the arc back rib 2, enhancing the deformation resistance of the left end of the arc back rib 2. At the same time, the left protrusion 21 also drives the left abutment 6 to move inward, applying inward pressure to the left rib plate 12, restricting the left rib plate 12 to the designed position and preventing it from bulging outward.

[0067] During concrete pouring, if the central rib plate 13 tends to bulge outwards, the central protrusion 22 will bulge outwards, simultaneously driving the left slider 4 to slide to the left and the right slider 5 to slide to the right, so that the left slider 4 abuts against the left end of the arc-shaped back rib 2 and the right slider 5 abuts against the right end of the arc-shaped back rib 2. At the same time, the central protrusion 22 presses the central rib plate 13 inwards through the central abutment 7 to prevent the central rib plate 13 from bulging outwards.

[0068] During the concrete pouring process, if the right rib plate 14 tends to bulge outward, the right protrusion 23 will bulge outward, driving the right slide bar 5 to slide to the right and press against the right end of the arc back rib 2, while simultaneously driving the right abutment 8 to press the right rib plate 14 inward.

[0069] With the above structure, when any part of the three ribs undergoes local outward deformation, the corresponding protrusion can drive the slider and the abutment to generate a reverse force, achieving precise self-response anti-deformation and effectively controlling the dimensional deviation of the arc surface.

[0070] refer to Figure 5The left abutment 6 and the right abutment 8 are symmetrically arranged. In a preferred embodiment, the left abutment 6 includes a left extension rod 61, an upper left vertical rod 62, an upper left seat 63, an upper left horizontal rod 64, an upper left plate 65, a lower left vertical rod 66, a lower left seat 67, a lower left horizontal rod 68, and a lower left plate 69.

[0071] One end of the left extension rod 61 is fixedly connected to the left protrusion 21, and the other end is hinged to both the lower end of the upper left vertical rod 62 and the upper end of the lower left vertical rod 66. The upper end of the upper left vertical rod 62 passes through the upper left seat 63, allowing it to rotate around its own axis within the upper left seat 63 and move up and down along its own axis. The upper end of the upper left vertical rod 62 is hinged to one end of the upper left horizontal rod 64, and the other end of the upper left horizontal rod 64 is fixedly connected to the upper left plate 65. The lower end of the lower left vertical rod 66 passes through the lower left seat 67, allowing it to rotate around its own axis within the lower left seat 67 and move up and down along its own axis. The lower end of the lower left vertical rod 66 is hinged to one end of the lower left horizontal rod 68, and the other end of the lower left horizontal rod 68 is fixedly connected to the lower left plate 69.

[0072] In a preferred embodiment, the arc surface 11 of the template 1 also has multiple transverse ribs 15, all of which are perpendicular to the left rib 12, the middle rib 13, and the right rib 14. The transverse ribs 15, the left rib 12, the middle rib 13, and the right rib 14 are set at the same height on the outer surface of the template 1, that is, the top surfaces of each rib are located on the same height plane.

[0073] The upper left plate 65 and the lower left plate 69 are respectively positioned at the intersection of the left rib plate 12 and the horizontal rib plate 15 on the upper and lower sides of the arc back rib 2.

[0074] Based on the above preferred scheme, when the left rib plate 12 tends to bulge outward, the left protrusion 21 moves outward, driving the left extension rod 61 to move outward. The left extension rod 61 simultaneously pushes the upper left vertical rod 62 and the lower left vertical rod 66, causing the upper left vertical rod 62 to rotate and move upward within the upper left seat 63, and the lower left vertical rod 66 to rotate and move downward within the lower left seat 67. The upward movement of the upper left vertical rod 62 causes the upper left horizontal rod 64 to translate inward toward the inside of the arc-back rib 2, causing the upper left abutment plate 65 to press against the intersection of the left rib plate 12 and the horizontal rib plate 15 on the upper side of the arc-back rib 2. The downward movement of the lower left vertical rod 66 causes the lower left horizontal rod 68 to translate inward toward the inside of the arc-back rib 2, causing the lower left abutment plate 69 to press against the intersection of the left rib plate 12 and the horizontal rib plate 15 on the lower side of the arc-back rib 2. This structure achieves a highly efficient response to single-point deformation, simultaneous longitudinal and transverse reinforcement (at least the left sliding bar 4 abuts against the left end of the arc-back rib 2 to strengthen the pressure of the arc-back rib 2 on the rib plate), significantly enhancing the lateral pressure resistance of the left rib plate area on the arc surface. The longitudinal and transverse rib plates form an orthogonal grid structure on the back of the template 1, significantly improving the overall stiffness and bending resistance of the template 1 and reducing the deflection deformation of the template 1 during casting. The abutment acts at the intersection of the longitudinal and transverse ribs, and the pressure applied by the abutment can be dispersed and transmitted in both longitudinal and transverse directions, resulting in a better reinforcement effect than when acting at non-intersection points of the rib plates.

[0075] The right abutment 8 presses against the intersection of the right rib plate 14 and the transverse rib plate 15. The structure of the right abutment 8 is symmetrical to that of the left abutment 6, and the working principle is the same, so it will not be described again here.

[0076] refer to Figure 6 and Figure 7 In a preferred embodiment, the central support 7 includes a left inclined block 701, a left shaft 702, a left rotating rod 703, a left crossbar 704, a left rotating seat 705, a central rod 706, a connecting rod 707, a central pressure plate 708, a right rotating seat 709, a right crossbar 710, a right rotating rod 711, a right shaft 712, and a right inclined block 713.

[0077] The interconnection structure of the left inclined block 701, left shaft 702, left rotating rod 703, left crossbar 704, and left rotating seat 705 is symmetrical with the interconnection structure of the right inclined block 713, right shaft 712, right rotating rod 711, right crossbar 710, and right rotating seat 709 in the initial state.

[0078] One end of the left shaft 702 is fixedly connected to the left inclined block 701, and the other end of the left shaft 702 is hinged to the inner end of the left rotating rod 703. The left crossbar 704 passes through the left rotating seat 705, which can rotate in place, and the left crossbar 704 can move axially within the left rotating seat 705. One end of the left crossbar 704 is hinged to the outer end of the left rotating rod 703, and the other end is hinged to the left end of the middle rod 706.

[0079] The middle part of the middle rod 706 is fixed to one end of the connecting rod 707. The other end of the connecting rod 707 is fixedly connected to the middle pressure plate 708. The two ends of the middle pressure plate 708 are respectively facing the middle rib plate 13 on the upper and lower sides of the arc back rib 2.

[0080] One structure of the intermediate pressure plate 708 includes a U-shaped body 7081, an upper intermediate plate 7082, and a lower intermediate plate 7083. A connecting rod 707 is fixedly connected to the vertical surface of the U-shaped body 7081, and the upper intermediate plate 7082 and the lower intermediate plate 7083 are respectively vertically connected to the two horizontal ends of the U-shaped body 7081.

[0081] The upper middle plate 7082 is attached to the intersection of the middle rib plate 13 and the transverse rib plate 15 on the upper side of the arc-back rib 2, and the lower middle plate 7083 is attached to the intersection of the middle rib plate 13 and the transverse rib plate 15 on the lower side of the arc-back rib 2. When the middle rib plate 13 has an outward convex tendency, the upper middle plate 7082 and the lower middle plate 7083 simultaneously apply inward pressure to the middle rib plate 13 and the transverse rib plate 15 from the upper and lower sides to prevent the middle rib plate 13 and the transverse rib plate 15 from warping and deforming.

[0082] The structure of the U-shaped body 7081 makes the middle pressure plate 708 U-shaped in general, which is spaced around the outside of the arc back rib 2, ensuring that the pressure on the upper and lower ribs is applied synchronously, and that it does not interfere with other parts of the arc back rib 2.

[0083] One end of the right crossbar 710 is hinged to the right end of the middle rod 706, and the other end is hinged to the outer end of the right rotating rod 711. The right crossbar 710 passes through the right rotating seat 709, which can rotate in place, and the right crossbar 710 can move axially within the right rotating seat 709. The inner end of the right rotating rod 711 is hinged to one end of the right shaft 712, and the other end of the right shaft 712 is fixedly connected to the right inclined block 713.

[0084] Compared to its inner end, the outer end of the left-turn lever 703 is closer to the center lever 706. Similarly, the outer end of the right-turn lever 711 is also closer to the center lever 706 compared to its inner end.

[0085] The irregular frame column template reinforcement structure also includes a bracket 9, a left guide sleeve 10a, a right guide sleeve 10b, and a spring 10c.

[0086] The left guide sleeve 10a wraps around the left shaft 702, and the right guide sleeve 10b wraps around the right shaft 712. Both the left guide sleeve 10a and the right guide sleeve 10b are fixed to the bracket 9. The left inclined block 701 and the left guide sleeve 10a are connected by a spring 10c, and the right inclined block 713 and the right guide sleeve 10b are connected by a spring 10c. The left rotating seat 705, the right rotating seat 709, the upper left seat 63, and the lower left seat 67 are all rotatably mounted in their original positions on the bracket 9. The right abutment 8, which is structurally symmetrical to the left abutment 6, includes the upper right seat 83 and the lower right seat 87, and is also rotatably mounted in their original positions on the bracket 9. The upper right seat 83 has the same structure and function as the upper left seat 63. The lower right seat 87 has the same structure and function as the lower left seat 67.

[0087] The left guide sleeve 10a guides the movement of the left shaft 702, restricting it from moving only linearly along the axial direction when under force, and supporting it to ensure good motion accuracy and reliability of the linkage mechanism. Similarly, the right guide sleeve 10b guides and supports the right shaft 712.

[0088] refer to Figure 8 and Figure 9 The middle component 7 has a left inclined block 701 and a right inclined block 713.

[0089] refer to Figure 10 and Figure 11 The left slider 4 and right slider 5 are structurally symmetrical. The left slider 4 has a left inclined groove 401, into which a left inclined block 701 is inserted, and the inclined surface of the left inclined block 701 fits against the inclined surface of the left inclined groove 401. The elastic force of the compressed spring 10c causes the inclined surface of the left inclined block 701 to press against the inclined surface of the left inclined groove 401. On the other side, the compressed spring 10c causes the inclined surface of the right inclined block 713 to press against the inclined surface of the right inclined groove 501 of the right slider 5. The preload of the spring improves the response efficiency of the middle abutment 7 in applying a reverse force to the outward convex deformation.

[0090] The template-reinforced structure includes the following three typical reinforcement modes.

[0091] The first scenario: The central rib plate 13 has a tendency to bulge outwards.

[0092] refer to Figure 12For the middle abutment 7 in the initial symmetrical state E, when the middle rib plate 13 protrudes outward, the middle protrusion 22 moves outward, simultaneously driving the left slider 4 to slide to the left and the right slider 5 to slide to the right. When the left slider 4 slides to the left, it pushes the left inclined block 701 outward (i.e., away from the arc surface 11) through the inclined surface cooperation. The left inclined block 701 drives the left shaft 702 to move outward. The left shaft 702 pushes the left rotating rod 703, which in turn pushes the outer end of the left crossbar 704 to rotate outward, while the inner end of the left crossbar 704 rotates inward. The middle section of the left crossbar 704 rotates and slides on the left rotating seat 705. The right crossbar 710 on the other side produces a symmetrical movement with the left crossbar 704. The left crossbar 704 and the right crossbar 710 simultaneously push the middle rod 706 to translate inward. The middle rod 706 does not rotate relative to the connecting rod 707. Thus, the middle rod 706 pushes the connecting rod 707 and the middle pressure plate 708 to move inward (i.e., towards the arc surface 11). The middle abutment 7 transforms into... Figure 12 State F causes the upper middle plate 7082 and lower middle plate 7083 at both ends of the middle pressure plate 708 to be further pressed against the intersection of the middle rib plate 13 and the transverse rib plate 15, thus reinforcing the longitudinal ends of the protruding middle rib plate 13 and resisting its outward deformation. During this process, since the left protrusion 21 does not contact the right wall of the left through hole 42 and the right protrusion 23 does not contact the left wall of the right through hole 52, the moving left slide bar 4 and right slide bar 5 do not press against the left protrusion 21 and right protrusion 23, so the left abutment 6 and right abutment 8 do not move. In this process, the left slide bar 4 sliding to the left and the right slide bar 5 sliding to the right further press against the left and right ends of the arc back rib 2, so that the arc back rib 2 further presses against the protruding middle rib plate 13 from the transverse direction. Therefore, this reinforcing structure can reinforce both the transverse ends of the middle rib plate 13 and the longitudinal ends of the middle rib plate 13, and has a good anti-deformation effect.

[0093] The second scenario: the left rib plate 12 has a tendency to bulge outwards.

[0094] When the left rib plate 12 protrudes outward, the left protrusion 21 moves outward, driving the left abutment 6 to press against the left rib plates 12 on both sides of the arc-back rib 2. Specifically, the left protrusion 21 drives the left extension rod 61 to move outward, causing the upper left vertical rod 62 to rotate and shuttle on the upper left seat 63, driving the upper left horizontal rod 64 to rotate inward, thereby causing the upper left plate 65 to further press against the intersection of the left rib plate 12 and the horizontal rib plate 15 on the upper side of the arc-back rib 2. Similarly, the outward movement of the left extension rod 61 also drives the lower left vertical rod 66 to rotate and shuttle on the lower left seat 67, causing the lower left horizontal rod 68 to rotate inward, thereby causing the lower left plate 69 to further press against the intersection of the left rib plate 12 and the horizontal rib plate 15 on the lower side of the arc-back rib 2. At the same time, the left protrusion 21 also drives the left slider 4 to slide to the left through the inclined surface of the left wall of the left through hole 42. When the left slider 4 slides to the left, it pushes the left inclined block 701 outward through the inclined plane, causing the left shaft 702 to move outward. This causes the outer end of the left rotating rod 703 to rotate towards the connecting rod 707, pushing the left crossbar 704 to move and rotate, which in turn pushes the middle rod 706 inward. This, in conjunction with the connecting rod 707 and the middle pressure plate 708, pushes the upper and lower ends of the middle rib plate 13 inward. At the same time, the left slider 4, sliding to the left, further presses against the left end of the arc-back rib 2. This action of pressing against the left end of the arc-back rib 2 and pressing against the middle rib plate 13 is equivalent to reinforcing the two ends of the left rib plate 12 laterally. Combined with the action of the upper left plate 65 pressing against the upper end of the left rib plate 12 and the lower left plate 69 pressing against the lower end of the left rib plate 12, the lateral and longitudinal ends of the outwardly protruding left rib plate 12 are simultaneously pressurized and reinforced, effectively resisting the outward deformation of the left rib plate 12. In this case, the right abutment 8 does not move.

[0095] The third scenario: the right rib plate 14 has a tendency to bulge outwards.

[0096] When the right rib plate 14 protrudes outward, the right protrusion 23 moves outward, driving the right abutment 8 to press the right rib plate 14 on both sides of the arc-back rib 2. This driving process is completely symmetrical with the action of the left protrusion 21 driving the left abutment 6 to press the left rib plate 12 on both sides of the arc-back rib 2, and will not be described in detail here. At the same time, the right protrusion 23 also drives the right slide bar 5 to slide to the right through the right wall slope of the right through hole 52, thereby pushing the right inclined block 713 outward through the inclined surface cooperation, and pushing the right shaft 712 outward. The subsequent movement is symmetrical with the action in the second case, which also makes the middle pressure plate 708 further press the middle rib plate 13 inward. That is, the reinforcing structure simultaneously pressurizes and reinforces both ends of the outward protruding right rib plate 14 in the lateral direction and both ends in the longitudinal direction, effectively resisting the outward deformation of the right rib plate 14. In this case, the left abutment 6 does not move.

[0097] In the above reinforcement mode, both the transverse and longitudinal ends of the deformation area are pressurized and reinforced, and the pressed arc back rib 2 also pressurizes and reinforces the convex deformation area itself, effectively correcting the deviation of the concrete column cross-section size, thereby effectively improving the yield of the concrete column cross-section size.

[0098] The irregular frame column formwork reinforcement structure provided in this application can be widely used in the formwork construction of irregular frame columns in public buildings, school stadiums, cultural and tourism buildings and municipal landmark projects, improving the one-time molding qualification rate and having high practical value.

[0099] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
