Description

Technical Field

[0001] The present invention relates to the field of column-tie-beam integrated construction, and in particular to a column-tie-beam integrated construction system. Background Art

[0002] During the slipform construction of high piers, multiple pier columns are usually set along the width of the bridge under the same cap beam, and tie beams are used to connect the pier columns. The tie beam casting section is the pier columns and tie beams within the tie beam elevation range, which are usually cast together. Before casting the tie beam casting section, support needs to be set up. Usually, through rods are buried on the main piers, and then a tie beam bracket (tie beam formwork support mechanism) is separately built on the through rods to facilitate the construction of the tie beam formwork.

[0003] However, in the existing technology, the tie beam formwork support mechanism and the pier formwork mechanism are two independent force-bearing systems. In the tie beam casting section, the tie beam support mechanism is re-erected at high altitude. After each tie beam casting is completed, the tie beam support mechanism needs to be dismantled, which is not only dangerous, but also time-consuming, labor-intensive and inefficient. Summary of the Invention

[0004] The present invention aims to provide a column-tie-beam integrated construction system to solve the problem of low construction efficiency and safety in the background art of erecting and dismantling tie-beam support mechanisms at high altitudes.

[0005] To achieve the above-mentioned object, the present invention adopts the following technical solution: a column-tie-beam integrated construction system, comprising an operating platform, a plurality of pier formwork mechanisms, a tie-beam support mechanism, and a tie-beam support mechanism, wherein each pier formwork mechanism is respectively provided on each pier column;

[0006] The operating platform surrounds all pier formwork mechanisms, and includes a lifting unit and a detachable platform. The detachable platform is arranged between adjacent pier formwork mechanisms, and the lifting unit includes a steel cable.

[0007] The tie beam support mechanism can replace the detachable platform and be set between the adjacent pier formwork mechanisms. The tie beam support mechanism includes a distribution bracket and two cantilever beams. The cantilever beams are connected to the cast sections of the two adjacent piers. The two sides of the distribution bracket are a rotating side and a free side respectively. The rotating side is rotatably connected to one of the cantilever beams, and the free side is detachably connected to the other cantilever beam. The distribution bracket is located directly below the tie beam, and the steel cable can be connected to the free side of the distribution bracket.

[0008] The beneficial effects of this program are:

[0009] 1. The bridge piers are constructed from bottom to top, so the system goes through the first non-tie beam casting section, the first tie beam casting section, the second non-tie beam casting section, and so on.

[0010] Multiple pier formwork mechanisms are connected into a whole through the operating platform, which increases the stability of the overall structure and improves the safety of construction; during the material turnover process, the materials only need to be hoisted to a fixed position on the operating platform, and the materials can be circulated between the piers manually, which improves the turnover efficiency and thus the construction efficiency; when constructing the non-tie beam casting section, a detachable platform is set up on the ground in advance, and each pier formwork mechanism is enclosed separately; when constructing the tie beam casting section, the detachable platform is dismantled and the tie beam support mechanism is set up without the need for an additional operating platform, which is convenient and fast, saves manpower and material resources for setting up and dismantling the operating platform, and improves construction efficiency and safety.

[0011] 2. During the tie beam casting section, the distribution bracket is positioned below the tie beam to provide support for the tie beam formwork. During the non-tie beam casting section, the distribution bracket is rotated around the cantilever beam to a vertical position, positioned to the side of the tie beam. This prevents interference between the distribution bracket and the tie beam, allowing the distribution bracket to rise smoothly along with the pier formwork. This entire process does not require dismantling the tie beam support mechanism. When the next tie beam casting section is reached, the distribution bracket is simply rotated to a horizontal position, eliminating the need to re-erect the tie beam support mechanism. This improves construction efficiency and safety compared to existing technologies.

[0012] Furthermore, it also includes a tie beam formwork mechanism, each pier formwork mechanism includes a side formwork unit, a lifting frame and a support frame, the side formwork unit can enclose the pier column, the lifting frame is arranged on the upper side of the side formwork unit, and the support frame is arranged on the inner side of the side formwork unit. The support frame includes a crossbeam, a tie rod and a column, the crossbeam is arranged horizontally and connected to the upper end of the column, the crossbeam and the lifting frame and the column are all detachably connected, the two ends of the crossbeam respectively extend to the outside of the side formwork unit, the two ends of the crossbeam are respectively provided with an adjustment unit, the upper end of the tie rod is connected to the adjustment unit, the two ends of the cantilever beam are respectively connected to the lower end of the tie rod of two adjacent pier formwork mechanisms, and the adjustment unit can drive the cantilever beam to move through the tie rod;

[0013] In the tie beam casting section, the distribution bracket is supported on the cantilever beam between two adjacent piers, and the tie beam formwork mechanism is supported on the distribution bracket; after the free side and the cantilever beam are disconnected, the adjustment unit drives the cantilever beam on that side to move, and the distribution bracket loses the cantilever beam support and rotates to vertical under the action of gravity.

[0014] The implementation steps of this plan are:

[0015] 1. Pre-embed the columns on the upper surface of the cast section of the pier below the tie beam casting section. Install the adjustment unit on the beam. Connect the adjustment unit, tie rod, cantilever beam and distribution bracket in sequence. Support the tie beam formwork mechanism on the distribution bracket and cast the tie beam casting section.

[0016] 2. Remove the part of the tie beam formwork mechanism except the tie beam bottom formwork, connect the steel cable to the free side, disconnect the free side from the cantilever beam on that side, drive the adjustment unit, and the adjustment unit drives the cantilever beam on that side to move, so that the free side of the distribution bracket loses the support of the cantilever beam on that side. The steel cable drives the free side to rotate under the action of gravity until the distribution bracket is vertical.

[0017] The beneficial effects of this program are:

[0018] 1. The erection of the tie beam support mechanism is an aerial operation. In order to support the distribution bracket, it is necessary to support the distribution bracket by setting a cantilever beam. In order to ensure the supporting effect, the cantilever beam needs to be set below the distribution bracket. However, if it is set up like this, when the distribution bracket rotates, the cantilever beam will definitely hinder the rotation of the distribution bracket. In this solution, an adjustment unit is set to drive the cantilever beam to move, so as to avoid the cantilever beam hindering the rotation of the distribution bracket.

[0019] 2. When the distribution bracket rotates, there is no need for manual operation standing next to the tie beam. By driving the adjustment unit, the distribution bracket can be rotated under the action of gravity. This is convenient and fast, and improves construction efficiency and production safety.

[0020] 3. There is no need to remove the bracket. After the distribution bracket is rotated, it is no longer at the bottom of the tie beam, but on the side of the tie beam. Therefore, when the pier formwork drives the distribution bracket to rise, it will not interfere with the cast tie beam.

[0021] 4. In order to prevent the distribution bracket from rotating too fast and causing the rotating side to be worn and damaged, this solution uses a steel cable to connect the free side, and then slowly lowers the free end of the distribution bracket.

[0022] Furthermore, the adjustment unit includes an adjustment jack, an adjustment hydraulic cylinder, and an adjustment slider. The adjustment slider is connected to the upper end of the pull rod. The adjustment slider slides along the length of the cross beam and is connected to the cross beam. The adjustment hydraulic cylinder is horizontally fixed to the cross beam. The output shaft of the adjustment hydraulic cylinder is connected to the adjustment slider. The adjustment jack is set on the adjustment slider. The upper end of the pull rod passes through the adjustment slider and is connected to the adjustment jack. The adjustment jack can drive the pull rod to rise or fall. With this arrangement, the output shaft of the adjustment hydraulic cylinder contracts, the adjustment slider slides along the length of the cross beam, and then drives the pull rod and the cantilever beam to move horizontally, so that the free side of the distribution bracket loses the support of the cantilever beam on that side, and then the distribution bracket rotates to a vertical position. The adjustment jack drives the pull rod and the cantilever beam to descend, so that the free side of the distribution bracket loses the support of the cantilever beam on that side, and then the distribution bracket rotates to a vertical position.

[0023] Furthermore, the free side of the distribution bracket protrudes relative to the side of the corresponding cantilever beam. Actuating the adjustment jack near the free side of the distribution bracket causes the cantilever beam and the free side of the distribution bracket to move downward, tilting the distribution bracket. This allows the steel cable to sequentially pass around the side of the tie beam near the rotational direction, the underside of the tie beam, and finally connect with the free side of the distribution bracket. With this arrangement, after the tie beam casting section is cast, the steel cable and the adjustment jack are used in conjunction to reduce the rotation speed of the distribution bracket.

[0024] Specifically:

[0025] First, drive the adjustment jack on the free side of the distribution bracket to move the pull rod and the cantilever beam downward, and then drive the free side of the distribution bracket to rotate downward until the free side of the distribution bracket is flush with the side of the cantilever beam, that is, the free side of the distribution bracket no longer protrudes backward relative to the rear cantilever beam. At this time, the cantilever beam still supports the distribution bracket, and the distribution bracket is in an inclined state due to the rotation, that is, a gap is created between the distribution bracket and the bottom of the cast tie beam. At this time, fix the upper end of the steel cable on the installation platform, and the worker stands on the side close to the rotating side of the distribution bracket, places a part of the steel cable in the gap between the distribution bracket and the bottom of the cast tie beam, and uses a rod-like object such as a steel bar to push the lower end of the steel cable from the free side of the distribution bracket to the rotating side of the distribution bracket. Then another worker catches the lower end of the steel cable on the free side of the distribution bracket and hooks the lower end of the steel cable to the free side of the distribution bracket.

[0026] If the steel cable is not passed from the rotating side of the distribution bracket to the free side, but is directly connected to the free side of the distribution bracket, then after the distribution bracket rotates, since the upper end of the steel cable and the distribution bracket are on both sides of the tie beam, and at the same time, the lower end of the steel cable is connected to the distribution bracket, when the pier formwork mechanism drives the tie beam support mechanism to rise, the steel cable will still interfere with the tie beam, thereby preventing the tie beam support mechanism from rising.

[0027] Then, continue to drive the adjustment jack on the free side of the distribution bracket to make the cantilever beam continue to move downward until the cantilever beam can no longer support the free side of the distribution bracket. At the same time, the worker pulls the steel cable and slowly lowers the free end of the distribution bracket to prevent the distribution bracket from being damaged due to excessive rotation speed.

[0028] Finally, the pier formwork mechanism drives the tie beam support mechanism to slide upward. During the entire upward sliding process of the pier formwork mechanism, the upper end of the steel cable is always fixed on any structure above the cantilever beam to facilitate reaching the second tie beam casting section. The steel cable is retracted upward to rotate the distribution bracket to a horizontal position. Otherwise, there is no other simple and safe way to rotate the distribution bracket to a horizontal position. At this time, the second tie beam has not yet been cast and formed. When the steel cable is pulled, neither the steel cable nor the distribution bracket will interfere with the tie beam.

[0029] Furthermore, the tie beam formwork mechanism includes a tie beam bottom formwork and two tie beam side forms. The tie beam bottom formwork is horizontally connected to the distribution bracket. The two tie beam side forms are respectively arranged on both sides of the tie beam. A corner sealing formwork is provided between the two tie beam side forms. The corner sealing formwork fills the space between one end of the bottom of the tie beam and the pier column. The tie beam bottom formwork is rotatably connected to one of the tie beam side forms. The tie beam side formwork is a rotating tie beam side formwork, and the other tie beam side formwork is a detachable tie beam side formwork. After the corner sealing formwork is removed, a strip gap is formed between the tie beam bottom formwork, the rotating tie beam side formwork, and the pier column. The end of the steel cable passes through the strip gap, the lower side of the tie beam, and is connected to the free side of the distribution bracket in sequence. This arrangement has the following effects:

[0030] 1. After pouring the tie beam section, the tie beam side formwork and corner sealing formwork are first removed. There is a gap between the tie beam bottom formwork and the pier column. The rotating pull rod drives the cantilever beam downward, so that the distribution bracket and the tie beam bottom formwork are tilted due to the rotation, so that the tie beam and the rotating tie beam side formwork are demoulded, and the rotating tie beam side formwork is leaning against the side of the tie beam; then, the rotating pull rod continues to drive the cantilever beam downward, so that the distribution bracket rotates to vertical; finally, the pier formwork mechanism drives the distribution bracket, the tie beam bottom formwork and the rotating tie beam side formwork to rise together. Due to the loss of support from the tie beam, the rotating tie beam side formwork rotates around the tie beam bottom formwork connection position under the action of gravity and collides with the tie beam bottom formwork. In the process of rising, under the action of wind load, it continuously collides with the tie beam bottom formwork, so that the concrete and other impurities remaining in the rotating tie beam side formwork and the tie beam bottom formwork are shaken off, so as to improve the concrete appearance quality of the tie beam during the next tie beam pouring.

[0031] 2. Since the tie beam bottom formwork and the rotating tie beam side formwork are connected, when used in conjunction with the adjusting hydraulic cylinder, the adjusting hydraulic cylinder drives the pull rod to move horizontally, and then drives the cantilever beam, distribution bracket, tie beam bottom formwork and rotating tie beam side formwork to move horizontally in turn, thereby realizing automatic demoulding between the rotating tie beam side formwork and the tie beam.

[0032] Furthermore, the operating platform also includes a peripheral platform, which simultaneously surrounds all pier formwork mechanisms. The detachable platform and the peripheral platform cooperate to separately surround each pier formwork mechanism. The peripheral platform and the detachable platform both include a ring beam, on which a platform connector is provided. The lifting frame includes a first channel steel unit and a second channel steel unit that are arranged horizontally and perpendicular to each other. The first channel steel unit and the second channel steel unit both include two back-to-back and parallel lifting channels, a number of connecting plates and connecting bolts. The two lifting channels are disconnected at a location near one end of the adjacent pier formwork mechanism. According to the disconnection position, the lifting channels are divided into a fixed section and a detachable section. The connecting bolts connect the connecting plates, the fixed section and the detachable section, and the detachable section of the lifting channel is connected to the ring beam of the detachable platform. With this arrangement, the fixed section and the detachable section can be quickly installed and removed through the connecting plates and the connecting bolts, thereby enabling the lifting frame and the detachable platform to be quickly installed and removed.

[0033] Furthermore, a support conversion unit is provided on the first channel steel unit. The support conversion unit includes two rectangular plates and a plurality of threaded rods. The upper ends of the threaded rods are connected to the first channel steel unit, and the lower ends of the threaded rods vertically pass through the two rectangular plates. Nuts are provided on the threaded rods. After tightening the nuts, the two rectangular plates can clamp the beam from the upper and lower sides. With this arrangement, after the rectangular plates clamp the beam, the rectangular plates provide vertical support for the beam. During the upward sliding of the pier formwork mechanism, since the distribution bracket rotates to one side of the beam, the load on the side of the beam close to the distribution bracket is greater, and the beam tends to slide toward this side. If the beam and the support conversion unit are fixedly connected, the tendency of the beam to slide is prevented by the support conversion unit. Therefore, the connection position between the beam and the support conversion unit is more prone to deformation. In this solution, after the rectangular plates clamp the beam, they allow the beam to move horizontally to a certain extent, thereby reducing the deformation of the beam.

[0034] Furthermore, it also includes a climbing control system, which includes a controller, several displacement sensors and horizontal attitude sensors. The oil circuit of each lifting jack is controlled separately. The climbing control system includes a controller and several displacement sensors. The displacement sensors are respectively set on each lifting jack. The displacement sensors can measure the distance the lifting jack climbs on the support rod. The displacement sensors are connected to the controller. The displacement sensors transmit the measured distance signal to the controller. The controller adjusts each lifting jack so that the distance signals of all displacement sensors are the same; the horizontal attitude sensor is set at the vertical foot position of the first channel steel unit and the second channel steel unit. The horizontal attitude sensor is connected to the controller. The horizontal attitude sensor uses the horizontal plane as the initial plane. When the angle between the lifting frame and the horizontal plane exceeds the angle setting value, the controller controls all lifting jacks to stop climbing. The controller calculates and displays the stroke amount that each jack needs to add based on the inclination angle and the distance of the lifting jacks measured by the horizontal attitude sensor, so as to adjust the first channel steel unit and the second channel steel unit to the horizontal. Such a setting has the following effects:

[0035] 1. Because the tie beam support mechanism and the pier formwork mechanism are lifted together, the lifting of each pier formwork mechanism must be synchronized. Otherwise, deformation of the tie beam support mechanism may occur, thereby reducing the bearing capacity of the entire structure. Therefore, this solution provides a climbing frame control system to ensure the synchronous lifting of each pier formwork mechanism.

[0036] Specifically, since the weight of each position of the pier formwork mechanism is different, the climbing distance is different when the power of the lifting jack is the same. Therefore, in this solution, the oil circuit of each lifting jack is controlled separately to meet the kinetic energy requirements of different lifting jacks; the climbing distance of each lifting jack on the support rod is measured by a displacement sensor. When the maximum difference in the climbing distance of several lifting jacks exceeds the distance setting value, the controller controls all lifting jacks to stop climbing, and then timely adjusts the displacement of the lifting jacks to prevent deformation of the tie beam support mechanism between the pier formwork mechanism.

[0037] 2. If there is a deviation in the displacement sensor and the deviation value is a fixed value, then after multiple climbs, the deviation will accumulate and become larger, and the horizontal attitude sensor will detect that the lifting frame is tilted. The controller calculates and displays the amount of stroke that needs to be added to each jack through the inclination angle measured by the horizontal attitude sensor and the distance of the lifting jacks, so that the lifting frame can be adjusted to the level in time.

Figure 7 Take the first channel steel unit 131 on the leftmost lifting frame as an example. Figure 13 As shown, according to the disconnection position 765, the lifting channel steel is divided into a fixed section 761 and a detachable section 762, and the disconnection positions 765 of the two lifting channel steels are staggered. Figure 13 There are four sets of bolts, each set of bolts includes six connecting bolts 763, and the connecting bolts 763 are all through the two lifting channel steels. Among them, the middle two sets of bolts pass through the fixed section 761 of the rear lifting channel steel and the detachable section 762 of the front lifting channel steel at the same time. Figure 7 As shown, the right ends of the two lifting channel steels of the first channel steel unit 131 are bolted to the platform connector.

[0068] The first channel steel unit 131 is further provided with a support conversion unit 14, which is arranged inside the lifting member. Figure 14 As shown, the support conversion unit 14 includes four threaded rods 141 and four rectangular plates 142. The upper two rectangular plates 142 are the second clamping plates, and the lower two rectangular plates 142 are the first clamping plates.

The four threaded rods 141 pass through the four corners of the first clamping plates and the second clamping plates respectively. After tightening the nuts 143, the two second clamping plates can clamp the two lifting channel steels of the first channel steel unit 131, and the two first clamping plates can also clamp the crossbeam 122.

[0069] The climbing control system includes a controller 810, a displacement sensor 820 and a horizontal attitude sensor 830. The displacement sensor 820 includes a signal transmitter and a receiver.

The receiver is set directly below the transmitter. The transmitter can send infrared rays and sound waves to the receiver. The receiver calculates and displays the distance between the receiver and the transmitter through the propagation speed of the infrared rays and sound waves and the time difference when they reach the receiver, and transmits the value of the distance to the controller 810. The controller 810 is set on the oil tank 840. The displacement sensor 820 transmits the measured climbing distance of the lifting jack 136 to the controller 810. The controller 810 controls the lifting jack 136 according to the data of the displacement sensor 820 to ensure that the displacement of each lifting jack 136 is equal.

[0070] The controller 810 is electrically connected to the solenoid valve 850, displacement sensor 820, and horizontal attitude sensor 830 on the oil circuit. The horizontal attitude sensor 830 is located at the vertical foot of the first channel steel unit 131 and the second channel steel unit 132. The horizontal attitude sensor 830 uses the horizontal plane as the initial plane and transmits the measured inclination angle to the controller 810. When the inclination angle exceeds the angle setting value, the controller 810 calculates and displays the amount of additional stroke required for each jack based on the inclination angle measured by the horizontal attitude sensor 830 and the distance between the lifting jacks 136. The controller 810 then controls all lifting jacks 136 to stop climbing. In this embodiment, the angle setting value is 2°.

[0076] d. Tie beam formwork mechanism

[0077] like Figure 15As shown, the tie beam formwork mechanism includes a tie beam bottom formwork 21 and two tie beam side forms 22. The tie beam bottom formwork 21 is horizontally bolted to a distribution bracket 34 (not shown in the figure). The two tie beam side forms 22 are respectively arranged on both sides of the tie beam body 5. A corner sealing formwork 23 is provided between the two tie beam side forms 22. The corner sealing formwork 23 is perpendicular to the tie beam side formwork 22 and the tie beam bottom formwork 21 at the same time, and is located between the bottom of the tie beam body 5 and the pier 4, that is, the upper end of the corner sealing formwork 23 is filled between one end of the tie beam bottom formwork 21 and the pier 4. The corner sealing formwork 23 is a rectangular formwork. The tie beam side formwork 22 is close to the lower ends of the two sides of the pier 4 and the corner sealing formwork 23 are connected by bolts on the upper sides of both ends; when the corner sealing template 23 is long, it can be designed into two symmetrical parts, each of which is connected to the tie beam side form 22, and then reinforced with the back rib in the prior art to facilitate disassembly; the tie beam bottom form 21 is rotatably connected to one of the tie beam side forms 22, and the tie beam side form 22 is a rotating tie beam side form, and the rotation connection method is also connected through a rotating component 35 (not shown in the figure), and the other tie beam side form 22 is a detachable tie beam side form, and the rotating side of the rotating tie beam side form and the distribution bracket 34 are located on the same side of the tie beam body 5. After the corner sealing template 23 is removed, the tie beam bottom form 21, the rotating tie beam side form and the pier 4 are formed as shown in the figure. Figure 16 As shown in the strip gap 630, the end of the steel cable 610 passes through the strip gap 630, the lower side of the tie beam body 5 and is connected to the pull ring 341 of the distribution bracket 34 in sequence; since the rotating tie beam side mold and the tie beam bottom mold 21 are rotatably connected, the steel cable 610 must pass through the strip gap 630 to reach the lower side of the tie beam body 5.

[0078] e. Specific implementation method (climbing control system controls the synchronization of climbing throughout the entire process):

[0079] 1. In the first non-tie beam casting section, pre-build an outer platform 710 and a removable platform 720 on the ground to enclose each pier formwork mechanism 1. Actuate lifting jacks 136, which drive lifting frame 13 to ascend on support rods 137, thereby driving the pier formwork mechanism 1 upward to below the first tie beam casting section. Columns 121 are embedded in the upper surface of the cast pier section below the tie beam casting section. The pier formwork mechanism 1 continues to slide upward to the first tie beam casting section. At this point, support transfer unit 14 is not involved in the system.

[0080] 2. Disconnect the fixed section 761 and the removable section 762 of the lifting channel steel on the lifting frame 13, remove the removable platform 720 and the removable side form 111, and connect the column 121, the beam 122, the tie rod 123, the cantilever beam 33 and the distribution bracket 34 in sequence.

[0081] 3. Support the tie beam bottom formwork 21 on the distribution bracket 34 , and connect the non-detachable side formwork 112 , the tie beam side formwork 22 , the corner sealing formwork 23 and the tie beam bottom formwork 21 .

[0082] 4. Pour the concrete of the tie beam pouring section. After the time required by the specification is reached, remove the detachable tie beam side formwork and corner sealing formwork 23. Before entering the second non-tie beam pouring section, remove the connecting bolts 763 of the free side of the distribution bracket 34 and the cantilever beam 33. Figure 8 As shown, the adjustment jack 124 is driven to move the front cantilever beam 33 downward, thereby driving the tie beam bottom mold 21 to rotate downward along with the free side of the distribution bracket 34 until the free side of the distribution bracket 34 is flush with the front side of the cantilever beam 33, that is, the main beam 342 on the front side of the distribution bracket 34 no longer protrudes forward relative to the front cantilever beam 33. Figure 17 As shown, the rotating assembly 35 is indicated by a circle, and the cross section of the tie beam body 5 is indicated by a rectangle. At this time, the front cantilever beam 33 still supports the distribution bracket 34, and the distribution bracket 34 and the tie beam bottom form 21 are tilted due to the rotation, that is, a gap is generated between the tie beam bottom form 21 and the bottom of the cast tie beam body 5, as shown in FIG. Figure 16 As shown, since the corner sealing formwork 23 has been removed, a strip-shaped gap 630 is formed between the tie beam bottom formwork 21 and the pier 4; during the rotation of the distribution bracket 34 and the tie beam bottom formwork 21, the tie beam body 5 and the rotating tie beam side formwork are demoulded, and finally the rotating tie beam side formwork is inclined against the side of the tie beam body 5;

[0083] At this time, if Figure 17 As shown, the worker stands on the side close to the rotating side of the distribution bracket 34, that is, the left side of the distribution bracket 34, hangs the electric hoist on the upper hanging point support 770 of the operating platform 7, and passes the lower end of the steel cable 610 from the strip gap 630 on the side of the tie beam body 5 close to the rotating side (the left side of the tie beam body 5) to the lower side of the tie beam body 5 (that is, the gap between the distribution bracket 34 and the bottom of the cast tie beam body 5), and finally connects it to the pull ring 341 (not shown in the figure) on the free side (the right end of the distribution bracket 34).

[0084] During this process, the bottom of the tie beam body 5 is blocked by sunlight, and it is dark and unclear, and the position of the lower end of the steel cable 610 cannot be seen clearly. At the same time, there may be foreign objects blocking the steel cable 610, making it difficult to smoothly pass the steel cable 610 through the bottom of the tie beam body 5; In this solution, if Figure 16As shown, the end of the steel cable 610 is placed on the tie beam bottom formwork 21 (since the end of the steel cable 610 is a hook, it usually has a certain weight) so that the part of the steel cable 610 close to the end can be pushed by a rod-shaped object 620 such as a steel bar. Since the part other than the end of the steel cable 610 is in the strip gap 630, the position of the steel cable 610 can be observed. The strip gap 630 provides a guide for the steel cable 610, and the end of the steel cable 610 is pushed from the lower side of the tie beam bottom formwork 21 to the upper side of the tie beam bottom formwork 21. Then another worker catches the end of the steel cable 610 on the upper side of the tie beam bottom formwork 21 and hooks the end of the steel cable 610 on the pull ring 341 on the free side of the distribution bracket 34 (not shown in the figure).

[0085] 5. Drive the adjustment jack 124 to move the cantilever beam 33 further downward until the cantilever beam 33 can no longer support the free side of the distribution bracket 34. At the same time, the electric hoist drives the steel cable 610 to slowly lower the free end of the distribution bracket 34 to prevent damage to the distribution bracket 34 due to excessive rotation speed.

[0086] 6. Insert the limiting rod 321 of the limiting member 32 through the cylinder 361, the first limiting hole, and the second limiting hole in sequence. Rotate the limiting portion 322 of the limiting member 32 to thread the limiting portion 322 and the cylinder 361. Then, insert the lower end of the limiting rod 321 into the limiting groove and tighten it. (This step may be performed depending on actual conditions such as wind speed.)

[0087] 7. Connect the lifting frame 13 and the crossbeam 122 through the support conversion unit 14, remove the bolts between the column 121 and the crossbeam 122, and drive the lifting jack 136, thereby driving the tie beam support mechanism (the portion excluding the column 121) and the pier formwork mechanism 1 to slide upward. When the lifting reaches the section to be poured for the next pier column 4, bolt the removable side form 111 to the non-removable side form 112, bolt the removable section and the fixed section of the lifting channel steel, and connect the removable platform 720 to the peripheral platform 710.

[0088] When the pier formwork mechanism 1 drives the distribution bracket 34, the tie beam bottom formwork 21 and the rotating tie beam side formwork to rise together, the rotating tie beam side formwork loses the support of the tie beam body 5, and under the action of gravity, it rotates around the connection position with the tie beam bottom formwork 21 and collides with the tie beam bottom formwork 21. In the process of rising, under the action of wind load, it continuously collides with the tie beam bottom formwork 21, so that the concrete and other impurities remaining in the rotating tie beam side formwork and the tie beam bottom formwork 21 are shaken off, so as to improve the concrete appearance quality of the tie beam body 5 when the tie beam body 5 is poured next time.

[0089] 8. After entering the second tie beam casting section, connect the fixed section 761 and the removable section 762 of the lifting channel steel on the lifting frame 13, and install the removable platform between adjacent pier formwork mechanisms; cast several sections of pier columns 4, slide the pier formwork mechanism 1 to the second tie beam casting section, and use the electric hoist to pull the steel cable 610 to return the distribution bracket 34 to the horizontal position. Bolt the free side of the distribution bracket 34 and the cantilever beam 33, and repeat steps 3-7.

[0090] Specific implementation steps of the climb control system:

[0091] Step 1: Prepare the synchronous lifting system for the multi-pillar construction platform described in Example 1, and adjust the displacement sensor 820 to the initial state;

[0092] Step 2: Simultaneously drive all lifting jacks 136 to climb on the support rods 137, thereby driving the lifting frame 13 and the pier formwork mechanism 1 to climb. The displacement sensor 820 transmits the measured climbing distance of the lifting jacks 136 to the controller 810. The controller 810 calculates the difference between the maximum distance and the minimum distance. When the maximum difference exceeds the distance setting value, the controller 810 controls all lifting jacks 136 to stop climbing together. The controller 810 controls each lifting jack 136 to climb individually until all displacement sensors 820 display the same distance.

[0093] Step 3. After the lifting jacks 136 have climbed multiple times, when the angle between the lifting frame 13 and the horizontal plane exceeds the angle setting value, the controller 810 controls all the lifting jacks 136 to stop climbing together, calculates and displays the stroke amount that each jack needs to add, so as to adjust the first channel steel unit 131 and the second channel steel unit 132 to the horizontal: the controller 810 controls each lifting jack 136 to climb individually until the lifting frame 13 is parallel to the horizontal plane, adjusts all displacement sensors 820 to the initial state, and repeats step 2.

[0094] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
