Support structure of round pier bent cap and installation method thereof

Abstract

This invention provides a support structure and installation method for a circular pier cap beam. Several embedded shear members are symmetrically embedded on both sides of the cap beam. The support structure includes an installation mechanism located at the top of the cap beam. Two triangular support frames are hinged to each other on both sides of the installation mechanism, and an adjustment component is provided on each frame to drive the triangular support frame to rotate around its hinge point. This allows the free end of the upper part of the triangular support frame to be connected and locked with the corresponding embedded shear member. The lower free ends of the two triangular support frames, away from the embedded shear members, are each connected to a semi-hoop, and the two semi-hoops have the freedom to move towards each other to form a clamp around the outer perimeter of the circular pier column. By employing a hinged rotation unfolding mechanism, the triangular support frames can be automatically unfolded and the semi-hoops can be closed, completely replacing the traditional high-altitude segmented hoisting, fine-tuning, and bolt tightening operations performed by construction workers in steep, narrow spaces.

Description

Technical Field

[0001] This invention relates to the field of visibility meters, and in particular to a support structure for a circular pier cap beam and its installation method. Background Technology

[0002] Construction of cast-in-place sections of continuous rigid frame bridge side spans often faces complex conditions such as high piers, steep terrain, and harsh geological environments. Under these conditions, the full-span scaffolding method is difficult to implement due to the difficulty in foundation treatment and the potential for slope instability; the pre-embedded through-bar method requires pre-drilling holes at the top of high piers, weakening the pier cross-sectional strength and introducing risks associated with high-altitude operations, thus limiting its applicability. While the clamping method has become the mainstream choice due to its advantages such as not requiring ground support and not damaging the main pier structure, existing technologies still have significant drawbacks.

[0003] First, traditional clamps often employ a segmented hoisting and high-altitude linear alignment method. In confined environments such as steep slopes and narrow spaces at the bottom of the cap beam, large lifting equipment is difficult to deploy, requiring construction workers to perform arduous fine-tuning and tightening at heights. This is not only inefficient but also carries a high risk of falls. Second, existing clamps primarily rely on the friction between the steel plate and the pier to resist loads, lacking a coordinated fixing mechanism with the upper cap beam structure, resulting in weak overall overturning resistance. Under fluctuating construction loads, eccentric forces, or strong winds in mountainous areas, the support system relying solely on friction is prone to slippage or even overturning, posing significant safety hazards. Furthermore, traditional methods do not effectively utilize the cap beam's own structure as an installation benchmark, leading to insufficient stability of the support system in the initial installation stage, making it difficult to meet the stringent precision requirements of high-pier, large-span construction. Therefore, this paper proposes a support structure and installation method for a circular pier cap beam to address these issues. Summary of the Invention

[0004] The main objective of this invention is to provide a support structure for a circular pier cap beam and its installation method, which solves the problems of difficulty in high-altitude alignment, high risk to personnel, and insufficient anti-overturning and anti-slip capabilities due to reliance on friction alone in the case of steep slopes and high piers.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a support structure for a circular pier cap beam and its installation method. Several pre-embedded shear members are symmetrically embedded on both sides of the cap beam. The support structure includes an installation mechanism set on the top of the cap beam. Triangular support frames are hinged on both sides of the installation mechanism, and an adjustment component is set on the mechanism to drive the triangular support frames to rotate around their hinge points, so that the free ends of the triangular support frames are connected and locked to the corresponding pre-embedded shear members. The lower free ends of the two triangular support frames away from the pre-embedded shear members are respectively connected to semi-hoops, and the two semi-hoops have the freedom to move toward each other to form a hoop that hugs the outer periphery of the circular pier column. The reaction force support is formed by locking the freedom between the lower part of the triangular support frame and the semi-hoops.

[0006] In the preferred embodiment, the top of the semi-hoop is fixed with an outwardly extending support platform, the top of the support platform is fixed with a connecting mechanism, and the free end below the triangular support frame is provided with a connecting foot that connects to the connecting mechanism. The connecting mechanism includes a connecting seat fixed to the top of the semi-hoop body. A partition is fixed in the connecting seat, which divides the connecting seat into an upper cavity and a lower cavity. The top of the upper cavity is open, and the connecting leg extends into the upper cavity and forms a sliding fit with the upper cavity. A reaction force component is provided in the cavity to provide reverse support force to the connecting leg.

[0007] In the preferred embodiment, sliding grooves are symmetrically arranged on the two side walls of the upper cavity, and sliding blocks that slide in cooperation with the sliding grooves are arranged on the side walls of the connecting feet; The reaction force assembly includes a reaction plate that can move along the sliding direction of the half hoop and abut against the connecting foot, and a drive mechanism set in the lower cavity. The reaction plate is located at the end of the connecting foot near the abutment of the half hoop. A through groove is provided on the partition plate, and the reaction plate passes through the through groove to be connected to the drive mechanism for transmission. The drive mechanism includes a rotating lead screw rotatably disposed in the lower cavity and two guide rods fixedly disposed in the lower cavity. A second drive motor is disposed on the outside of the lower cavity, and the output end of the second drive motor is connected to the rotating lead screw. The reaction plate is threadedly engaged with the rotating lead screw and simultaneously slidably engaged with the two guide rods.

[0008] In the preferred embodiment, the connecting seat is provided with a push-telescopic cylinder on the outer side of the upper cavity away from the semi-hoop docking point. The telescopic end of the push-telescopic cylinder can extend into the upper cavity and abut against the connecting foot.

[0009] In the preferred embodiment, both ends of the half-hoop are provided with a connecting plate, and the connecting plates of the two half-hoops are provided with a clamping mechanism; The engagement mechanism includes a slot on the docking plate of one half of the hoop, the outer side of which is open. An extension seat is provided on the docking plate of the other half of the hoop, and a displacement groove extending to the extension seat is provided on the docking plate. A locking mechanism that can slide in and out of the slot is slidably provided in the displacement groove. The locking mechanism is used to lock or unlock the engagement relationship. A push-pull telescopic cylinder for controlling the sliding of the locking mechanism is provided on the side of the extension seat away from the docking surface.

[0010] In the preferred embodiment, the locking mechanism includes a slide table slidably disposed on the side of the displacement groove away from the mating surface. The telescopic end of the push-pull telescopic cylinder is connected to the side of the slide table. An outer sleeve rod is provided on the side of the slide table close to the mating surface, which movably passes through the displacement groove. The outer sleeve rod can slide in and out of the slot opening through the sliding of the slide table. An adjusting screw is rotatably disposed inside the outer sleeve rod. A third drive motor is disposed on the side of the slide table away from the displacement groove. The output end of the third drive motor is connected to the adjusting screw rod. An inner thread sleeve is installed on the outer thread of the adjusting screw rod. Moving grooves are arranged in annular array on the outer sleeve rod. Connecting blocks that pass through the corresponding moving grooves are arranged in annular array on the outer side of the inner thread sleeve. The other end of the connecting block is connected to a locking ring. The docking plate is provided with two sliding grooves extending to the extension seat. The two sliding grooves are located on the upper and lower sides of the displacement groove, respectively. The sliding table is provided with a sliding seat that matches the sliding groove. Both the sliding seat and the sliding groove are L-shaped and match each other.

[0011] In the preferred embodiment, the installation mechanism is located on the top of the cap beam and forms a detachable fixed connection with the pre-embedded shear members on both sides. The installation mechanism and the adjustment components on it are detachably hinged to the triangular support frame.

[0012] In the preferred embodiment, the triangular support frame includes a horizontal support frame and an inclined support frame fixed to the bottom of the horizontal support frame. The end of the horizontal support frame near the pre-embedded shear member is provided with a connecting ear plate that can cooperate with it. The connecting ear plate is provided with several pin holes. The end of the horizontal support frame near the pin holes is also provided with a first hinge hole for hinged with the installation mechanism, and the other end is provided with a second hinge hole for hinged with the adjustment component. There are two pre-embedded shear members on each side. The pre-embedded shear members are provided with connecting grooves that are adapted to the connecting ear plates. Through holes corresponding to pin holes are provided on the two side walls of the connecting grooves. Automatic pins that can pass through the through holes and the corresponding pin holes are provided on the outside of the through holes. The automatic pins of the two pre-embedded shear members on the same side are located on the opposite sides of the two. The installation mechanism includes a U-shaped frame that can be erected on the top of the cap beam. Fixing plates are symmetrically arranged on opposite sides of two pre-embedded shear members on the same side. Temporary fixing components that clamp the corresponding fixing plates are provided at the ends of the U-shaped frame. The temporary fixing assembly includes a rotary clamping telescopic cylinder fixed to the side of the end of the U-shaped part, and a clamping plate is provided on the telescopic end of the rotary clamping telescopic cylinder; The width of the U-shaped frame is less than the distance between two embedded shear members on the same side, and slope guide seats are fixedly installed on the opposite sides of the top of the two embedded shear members on the same side. The connection between the U-shaped frame and the triangular support frame is provided with a first hinge mechanism that can be detachably hinged to the first hinge hole. The adjustment assembly includes a vertical frame fixed at the center of the top of the U-shaped frame. Several adjustment telescopic rods are hinged to both sides of the top of the frame. The telescopic ends of the adjustment telescopic rods are provided with a second hinge structure, which can be detachably hinged to the second hinge hole.

[0013] In the preferred embodiment, both the first hinge mechanism and the second hinge structure include a housing. The width of the housing is adapted to the width between the inner sides of the horizontal support frame. The housing has a cavity inside, and two bearing seats are symmetrically arranged on the inner wall of the cavity. A positive and negative threaded screw is rotatable between the two bearing seats. A first drive motor is arranged on the side of one of the bearing seats opposite to the positive and negative threaded screw. The output end of the first drive motor is connected to the positive and negative threaded screw. The two opposite threaded segments of the positive and negative threaded screw are respectively threaded with movable seats. The ends of the two movable seats extend outside the bearing seats, and a connecting shaft that movably passes through the housing is arranged on the opposite side. The connecting shaft is used to hinge with the first hinge hole or the second hinge hole. The crossbeam of the upright is equipped with two retraction support components, each corresponding to one of the two adjustment components. Specifically, each component includes a support telescopic cylinder fixed to the crossbeam of the upright, with the telescopic end of the support telescopic cylinder facing the corresponding adjustment telescopic rod and equipped with a support seat.

[0014] The method includes: S1. Complete the installation of the support structure on the ground. At this time, the triangular support frame and the semi-hoop are in the open and closed state. S2. Use hoisting equipment to hoist the support structure onto the cap beam, and temporarily fix the installation mechanism onto it; S3. By adjusting the components, drive the triangular support frame and the half hoop on it to rotate around the hinge point until the free end above the triangular support frame cooperates with the pre-embedded shear component, and the two half hoops wrap around the round pier column. S4. Lock the free end of the embedded shear member and the upper part of the triangular support frame, and lock the two half-hoops tightly around the outside of the round pier column. At the same time, lock the lower free end of the triangular support frame and the half-hoops to form a reaction support. S5. Gradually disconnect the installation mechanism from the triangular support frame and the cap beam, and then move them away using hoisting equipment.

[0015] This invention provides a support structure and installation method for a circular pier cap beam. By employing a hinged rotation unfolding mechanism, the triangular support frame can be automatically unfolded and the semi-hoop body can be closed. This completely replaces the traditional high-altitude segmented hoisting, fine-tuning, and bolt tightening operations performed by construction workers in steep and narrow spaces. Precise positioning can be achieved without frequent adjustments to the position using large lifting equipment, significantly reducing the risk of falls from heights. At the same time, by using the pre-embedded shear components of the cap beam and fixing them to the triangular support frame, a rigid connection is formed between the support system and the already formed cap beam structure. This changes the traditional force mode of the hoop, which relies solely on friction, and constructs a dual stabilizing system of "pulling from above and hugging from below." This greatly enhances the overturning and sliding resistance of the support system, effectively resisting strong winds in mountainous areas and eccentric loads during construction, ensuring the structural stability of high piers and large-span construction.

Detailed Implementation

[0018] Example 1 like Figures 1-23As shown, a support structure for a circular pier cap beam is provided. Several embedded shear members 6 are symmetrically embedded on both sides of the cap beam 2. In this embodiment, there are two embedded shear members 6 on each side. The support structure includes a detachable mounting mechanism 3 set on the top of the cap beam 2. Triangular support frames 4 are detachably hinged on both sides of the mounting mechanism 3, and an adjustment component is provided on it to drive the triangular support frame 4 to rotate around its hinge point so that the free end of the upper part of the triangular support frame 4 is connected and locked with the corresponding embedded shear member 6. The adjustment component and the triangular support frame 4 are detachably connected. The lower free ends of the two triangular support frames 4 away from the embedded shear members 6 are respectively connected to half-hoops 50, and the two half-hoops 50 have the freedom to move toward each other to form a hoop 5 that hugs the outer periphery of the circular pier 1. The reaction force support is formed by locking the freedom between the lower part of the triangular support frame 4 and the half-hoops 50.

[0019] This design, through a unique rotating installation structure, allows the triangular support frame 4 to rotate flexibly around the installation mechanism 3, thus enabling it to smoothly connect with the pre-embedded shear component 6 and accurately align and install the clamp 5 even under the obstruction and restriction of the cap beam 2. This effectively overcomes the problem of traditional linear hoisting methods being unable to operate in confined spaces, significantly reducing construction safety risks. At the same time, it constructs a dual stable force-bearing system of upper pull and lower clamp, greatly enhancing the structure's anti-slip and anti-overturning capabilities and ensuring the overall stability of the support system. Furthermore, after installation, it can be dismantled by separating the installation mechanism 3 from the triangular support frame 4 and the cap beam 2, avoiding the occupation of the construction space on top of the cap beam 2.

[0020] The triangular support frame 4 includes a horizontal support frame 40 and a diagonal brace 41 fixed at the bottom of the horizontal support frame 40. Both the horizontal support frame 40 and the diagonal brace 41 are frame structures with a crossbeam in the middle.

[0021] The horizontal support frame 40 is provided with a connecting ear plate 401 that can cooperate with the pre-embedded shear member 6 at one end. The connecting ear plate 401 is provided with a number of pin holes 402. In this embodiment, the number of pin holes 402 on each connecting ear plate 401 is two. The horizontal support frame 40 is also provided with a first hinge hole 403 for hinged with the mounting mechanism 3 at one end near the pin holes 402, and a second hinge hole 404 for hinged with the adjustment component at the other end.

[0022] The embedded shear member 6 is provided with a connecting groove 601 that is adapted to the connecting ear plate 401. Both ends of the connecting groove 601 are open, which can satisfy the effect of rotating the connecting ear plate 401 into it. In addition, the positional relationship between the first hinge hole 403 and the embedded shear member 6 satisfies the requirement of rotating the connecting ear plate 401 into the connecting groove 601. In this embodiment, the triangular support frame 4 can rotate 90° around its hinge point.

[0023] Through holes 602 corresponding to pin holes 402 are provided on the two side walls of the connecting groove 601. An automatic pin 603 that can pass through the through hole 602 and the corresponding pin hole 402 is provided on the outside of the through hole 602, thereby achieving the effect of locking the horizontal support frame 40.

[0024] In this embodiment, the automatic pins 603 of the two pre-embedded shear members 6 on the same side are located on opposite sides of each other.

[0025] It should be noted that the automatic latch 603 is preferably a screw-type electric telescopic cylinder.

[0026] In the preferred embodiment, the telescopic end of the automatic latch 603 is provided with a thread, which can be further locked by threading a nut onto it.

[0027] In the preferred embodiment, the installation mechanism 3 is located on top of the cap beam 2 and forms a detachable fixed connection with the pre-embedded shear members 6 on both sides.

[0028] The installation mechanism 3 includes a U-shaped frame 30 that can be mounted on the top of the cover beam 2. The groove on the U-shaped frame 30 is adapted to the width of the top of the cover beam 2, so that it can be mounted on the top of the cover beam 2. The U-shaped frame 30 is specifically composed of two U-shaped parts.

[0029] Two pre-embedded shear members 6 on the same side are symmetrically provided with fixing plates 604. The fixing plates 604 are located at the ends of the two U-shaped members respectively. Temporary fixing components 36 that clamp the corresponding fixing plates 604 are provided on the opposite sides of the ends of the two U-shaped members. Thus, by clamping the fixing plates 604 with the temporary fixing components 36, the installation mechanism 3 is temporarily fixed on the cap beam 2.

[0030] The temporary fixing assembly 36 includes a rotary clamping telescopic cylinder 360 fixed to the side of the end of the U-shaped part, and a clamping plate 361 is provided on the telescopic end of the rotary clamping telescopic cylinder 360.

[0031] It should be noted that, in this embodiment, the rotary clamping telescopic cylinder 360 is preferably a hydraulic rotary clamping telescopic cylinder, which can control the clamping plate 361 to rotate 90° while extending and retracting. Thus, when disassembling and assembling the installation mechanism 3, its telescopic end remains extended while the clamping plate 361 is in a state of avoidance with the fixing plate 604. When fixing is required, the telescopic end is retracted while the clamping plate 361 rotates to the bottom of the fixing plate 604 to clamp it.

[0032] Furthermore, in order not to affect the automatic pin 603 passing through the through hole 602, the width of the U-shaped frame 30 is less than the distance between the two pre-embedded shear members 6 on the same side. At the same time, in order to enable the U-shaped frame 30 to be accurately inserted between the two pre-embedded shear members 6 on the same side, slope guide seats 605 are fixedly installed on the opposite sides of the top of the two pre-embedded shear members 6 on the same side. Thus, during the lowering process, the U-shaped frame 30 is installed under the guidance and limiting action of the slope guide seats 605.

[0033] The connection between the U-shaped frame 30 and the triangular support frame 4 is provided with a first hinge mechanism 32 that can be detachably hinged to the first hinge hole 403.

[0034] The adjustment assembly includes a vertical frame 31 fixed at the center of the top of the U-shaped frame 30. The frame 31 is a frame structure with a crossbeam in the middle. Several adjustable telescopic rods 33 are hinged to both sides of the top of the frame 31. The telescopic ends of the adjustable telescopic rods 33 are provided with a second hinge structure 34. The second hinge structure 34 can be detachably hinged to the second hinge hole 404, so that the rotation of the triangular support frame 4 around the first hinge hole 403 can be controlled by adjusting the telescopic rods 33.

[0035] In this embodiment, there are two adjusting telescopic rods 33 on each side. The second hinge structure 34 is fixedly installed on the telescopic ends of the two adjusting telescopic rods 33 on the same side. The adjusting telescopic rods 33 are preferably hydraulic telescopic cylinders and are equipped with corresponding hydraulic stations and their synchronous telescopic control systems.

[0036] Both the first hinge mechanism 32 and the second hinge structure 34 include a housing 320. The housing 320 has a cavity inside. Two bearing seats 321 are symmetrically arranged on the inner wall of the cavity. A forward and reverse threaded screw 322 is rotatable between the two bearing seats 321. A first drive motor 323 is arranged on the side of one of the bearing seats 321 away from the forward and reverse threaded screw 322. The output end of the first drive motor 323 is connected to the forward and reverse threaded screw 322 for transmission, thereby driving the forward and reverse threaded screw 322 to rotate.

[0037] The two opposite threaded segments of the positive and negative threaded screw 322 are respectively threaded with movable seats 324. The ends of the two movable seats 324 extend outside the bearing seat 321, and the opposite side is provided with a connecting shaft 325 that moves through the housing 320. Specifically, the housing 320 is provided with a hole for the connecting shaft 325 to move through, so that the two connecting shafts 325 can be controlled to pass through the housing 320 by rotating the positive and negative threaded screw 322.

[0038] When it is necessary to hinge with the first hinge hole 403 or the second hinge hole 404, the connecting shaft 325 can be controlled to pass through the housing 320 and move through the first hinge hole 403 or the second hinge hole 404 to form the above-mentioned hinge structure; when it is necessary to disconnect, the connecting shaft 325 can be controlled to retract into the housing 320 and disengage from the first hinge hole 403 or the second hinge hole 404.

[0039] It should be noted that, in order to avoid the connection from being broken due to the axial movement of the triangular support frame 4 along the connecting shaft 325 after the connecting shaft 325 is connected to the first hinge hole 403 or the second hinge hole 404, the width of the housing 320 is matched with the width between the inner sides of the horizontal support frame 40, so as to play an axial limiting role. In addition, the crossbeam in the horizontal support frame 40 and the housing 320 maintain a sufficient distance to avoid interference during rotation.

[0040] In a preferred embodiment, in order to further improve the stability of the movable seat 324, a limiting groove 326 is provided on the inner wall surface of the housing 320, and a limiting block 327 that slides with the limiting groove 326 is fixed on the movable seat 324.

[0041] A retraction support assembly 35 is provided on the crossbeam of the upright frame 31. It is used to support the adjusting telescopic rod 33 after the second hinge structure 34 is released from the hinge relationship with the triangular support frame 4, so as to prevent unnecessary swinging and collision at the moment of release.

[0042] There are two recovery support components 35, each corresponding to one of the two adjustment components. Specifically, each component includes a support telescopic cylinder 350 fixed on the crossbeam of the upright frame 31. The support telescopic cylinder 350 is preferably a hydraulic cylinder. The support telescopic cylinders 350 of the two recovery support components 35 are arranged side by side on a crossbeam. The telescopic end of the support telescopic cylinder 350 faces the corresponding adjustment telescopic rod 33 and is provided with a support seat 351.

[0043] With this design, before the second hinge structure 34 is released from the hinge relationship with the triangular support frame 4, the support base 351 can be brought into contact with the adjusting telescopic rod 33 by extending the telescopic cylinder 350. Then, the hinge relationship is released, and the adjusting telescopic rod 33 and the support telescopic cylinder 350 are retracted simultaneously.

[0044] In the preferred embodiment, the top of the semi-hoop 50 is fixed with an outwardly extending support platform 501, thereby creating conditions for connection with the triangular support frame 4. The top of the support platform 501 is symmetrically fixed with two connecting mechanisms 51. The diagonal brace 41 slides with the corresponding connecting mechanism 51 through the connecting foot 410 fixed on its bottom free end.

[0045] The connecting mechanism 51 includes a connecting seat 510 fixed to the top of the half hoop 50. A partition 511 is fixed in the connecting seat 510, which divides the connecting seat 510 into an upper cavity 512 and a lower cavity 513. The top of the upper cavity 512 is open, and sliding grooves 514 are symmetrically arranged on the two side walls of the upper cavity 512. The connecting foot 410 extends into the upper cavity 512, and a sliding block 411 that slides with the sliding groove 514 is provided on its side wall. This allows the half hoop 50 to slide through the sliding block 411 and the sliding groove 514, thereby creating conditions for the two half hoops 50 to hug each other.

[0046] It should be noted that the orientation of the sliding groove 514 satisfies the requirement that the two half-hoops 50 can move toward each other. At the same time, the sliding block 411 is a rectangular body, so that the half-hoops 50 can slide only along the length of the sliding groove 514, avoiding unnecessary flipping.

[0047] Furthermore, in order to provide counter-support to the triangular support frame 4 after the clamp 5 is engaged, a reaction force assembly 516 is provided in the lower cavity 513 to provide reverse support force to the connecting foot 410. The reaction force assembly 516 includes a reaction plate 5164 that can move along the sliding direction of the half clamp 50 and abut against the connecting foot 410, and a drive mechanism provided in the lower cavity 513. The reaction plate 5164 is located at one end of the connecting foot 410 near the abutment of the half clamp 50. A through groove 5165 is provided on the partition 511, and the reaction plate 5164 passes through the through groove 5165 and is connected to the drive mechanism for transmission.

[0048] It should be noted that the length of the through groove 5165 meets the movement requirements of the reaction plate 5164.

[0049] The drive mechanism includes a rotating lead screw 5160 rotatably disposed in the lower cavity 513 and two guide rods 5161 fixedly disposed in the lower cavity 513. The rotating lead screw 5160 is rotatably disposed in the lower cavity 513 via bearings at both ends. A second drive motor 5162 is disposed on the outside of the lower cavity 513 via a connecting seat 510. The output end of the second drive motor 5162 is connected to the rotating lead screw 5160 for transmission. The reaction plate 5164 is threadedly engaged with the rotating lead screw 5160 and slidably engaged with the two guide rods 5161. Thus, the movement control of the reaction plate 5164 is realized through the rotation of the rotating lead screw 5160 and the guidance of the two guide rods 5161.

[0050] Before the two half-hoops 50 are joined together, the reaction plate 5164 is moved away from the connecting foot 410 and pressed against the inner wall of the upper cavity 512. After the two half-hoops 50 are joined together, the reaction plate 5164 is moved to abut against the connecting foot 410, thereby providing reaction support to the bottom of the triangular support frame 4 so that it can be effectively supported on the hoop 5.

[0051] In the preferred embodiment, in order to avoid unnecessary sliding collisions caused by changes in posture of the semi-hoop 50 before it closes, the connecting seat 510 is provided with a push-telescopic cylinder 515 on the outer side of the upper cavity 512 away from the docking point of the semi-hoop 50. The telescopic end of the push-telescopic cylinder 515 can extend into the upper cavity 512 and abut against the connecting foot 410.

[0052] Such a design, as Figure 17 As shown, the two semi-hoops 50 can maintain the maximum distance between them by the contact between the push-pull telescopic cylinder 515 and the connecting foot 410, so that unnecessary sliding and collision will not occur during the above rotation process.

[0053] In the preferred embodiment, in order to achieve automatic clamping of the clamp 5, both ends of the half-clamp 50 are provided with docking plates 502, and clamping mechanisms 52 are provided on the docking plates 502 of the two half-clamps 50.

[0054] The clamping mechanism 52 includes a slot 520 on the docking plate 502 of one of the half-hoops 50, the outer side of the slot 520 being open. An extension seat 521 is provided on the docking plate 502 of the other half-hoop 50. A displacement groove 522 extending to the extension seat 521 is provided on the docking plate 502. A locking mechanism 523 that can slide in and out of the slot 520 is slidably provided in the displacement groove 522. The locking mechanism 523 is used to lock or unlock the clamping relationship. A push-pull telescopic cylinder 524 for controlling the sliding of the locking mechanism 523 is provided on the side of the extension seat 521 away from the docking surface.

[0055] The locking mechanism 523 includes a slide table 5230 slidably disposed on the side of the displacement groove 522 away from the mating surface. Specifically, the mating plate 502 is provided with two slide grooves 525 extending to the extension seat 521. The two slide grooves 525 are located on the upper and lower sides of the displacement groove 522, respectively. The slide table 5230 is provided with a slide seat 5231 that matches the slide groove 525. Both the slide seat 5231 and the slide groove 525 are L-shaped and can be matched to ensure the stability during sliding. At the same time, the telescopic end of the push-pull telescopic cylinder 524 is connected to the side of the slide table 5230.

[0056] A sliding table 5230 is provided with an outer sleeve rod 5232 that movably passes through the displacement groove 522 on the side near the mating surface. The outer sleeve rod 5232 can slide in and out of the opening of the slot 520 by sliding the sliding table 5230. An adjusting screw 5233 is rotatably provided inside the outer sleeve rod 5232. The adjusting screw 5233 is rotatably provided in the outer sleeve rod 5232 through a bearing. A third drive motor 5234 is provided on the side of the sliding table 5230 away from the displacement groove 522. The output end of the third drive motor 5234 is connected to the adjusting screw 5233 for transmission, thereby driving the adjusting screw 5233 to rotate.

[0057] An internal threaded sleeve 5236 is installed on the external thread of the adjusting screw 5233. The outer sleeve 5232 has a ring array of moving grooves 5235. In this embodiment, there are four moving grooves 5235. The outer ring array of the internal threaded sleeve 5236 has connecting blocks 5237 that pass through the corresponding moving grooves 5235. The other end of the connecting block 5237 is connected to a locking ring 5238. Thus, by adjusting the rotation of the adjusting screw 5233, the internal threaded sleeve 5236 can move along its axial direction under the restriction of the connecting block 5237 and the moving grooves 5235, thereby driving the locking ring 5238 to move. Through the pressing of the locking ring 5238 with the mating plate 502 with the slot 520, the two clamps 50 are clamped together.

[0058] This design allows the outer sleeve rod 5232 of the locking mechanism 523 to be moved to a position outside the slot 520 by retracting the push-pull telescopic cylinder 524 before the two half-hoops 50 are engaged. This ensures that the two half-hoops 50 are not rotated and aligned with the mating plate 502 with the slot 520. Once the two half-hoops 50 are in place, the outer sleeve rod 5232 of the locking mechanism 523 can be moved into the slot 520 by pushing the push-pull telescopic cylinder 524. At the same time, the locking ring 5238 is positioned on the side away from the mating surface. Then, by adjusting the rotation of the lead screw 5233, the locking ring 5238 is pressed against the mating plate 502 with the slot 520. This achieves a clamping effect by cooperating with the slide table 5230. When unlocking is required, the above operation can be reversed. In addition, by using the push-pull telescopic cylinder 515 to restrict the posture of the semi-hoop 50 during rotation, the locking mechanism 523 can be ensured to slide into the slot 520 according to the above locking requirements.

[0059] In another embodiment, a method for installing the support structure of the aforementioned circular pier cap beam is disclosed, the method comprising: S1. Complete the installation of the support structure on the ground. At this time, the triangular support frame 4 and the semi-hoop 50 are in the open and closed state.

[0060] S2. The supporting structure is hoisted onto the cap beam 2 using hoisting equipment, and the installation mechanism 3 is temporarily fixed onto it.

[0061] S3. By adjusting the components, drive the triangular support frame 4 and the half hoop 50 on it to rotate around the hinge point until the free end above the triangular support frame 4 cooperates with the pre-embedded shear member 6, and the two half hoop 50 wrap around the round pier column 1.

[0062] S4. Lock the free ends of the pre-embedded shear member 6 and the triangular support frame 4 above, and lock the two half-hoops 50 tightly around the outside of the round pier column 1. At the same time, lock the free end of the triangular support frame 4 below and the half-hoops 50 to form a reaction support.

[0063] S5. Gradually disconnect the installation mechanism 3 from the triangular support frame 4 and the cap beam 2, and then move them away using hoisting equipment.

[0064] It should be noted that when it is necessary to remove the supporting structure, the above arrangement can be reversed.
