Description

Technical Field

[0001] The present invention relates to the construction field of columnar structures such as bridges, aqueducts, and wharves, especially an intelligent construction system and method for the climbing cyclic formwork of columnar structures. Background Art

[0002] At present, the piers of bridges, aqueducts, and wharves are characterized by a large number and wide distribution. The construction of the formwork for these columnar structures mainly adopts the formwork turnover method, climbing formwork method, or slip formwork method. The above three construction methods all have some problems: 1. The formwork turnover construction has low cost, but has problems such as high safety risks and high dependence on lifting equipment. 2. The climbing formwork construction is safe and reliable, but has high construction costs and low efficiency; 3. The slip formwork construction has high efficiency, but the construction quality is not good. The above construction processes all have certain limitations and cannot balance construction efficiency, quality, safety, and cost. CN202247703U records a hydraulic climbing frame formwork turnover and slip formwork device for high piers, which combines the characteristics of the formwork turnover, climbing formwork, and slip formwork structures by adopting the main load-bearing beam scheme and has low dependence on the lifting device. The problem is that this scheme results in a relatively high self-weight of the entire construction device, and all these weights are borne on the anchor cones of the pier, which requires more pre-buried anchor cones or has higher safety risks. Moreover, the existing climbing formwork guide rail passes through the outer formwork and is connected to the anchor cone. Since there is a back rib structure on the back of the outer formwork, a hanging boot needs to be set between the climbing formwork guide rail and the anchor cone, which constitutes a cantilever structure and increases the safety risk. Affected by the climbing frame structure, the existing construction platform needs to set adjustable diagonal bracing structures to increase the strength of the climbing frame. This further increases the self-weight of the climbing frame. Summary of the Invention

Detailed implementation manners

[0045] Example 1: As Figures 1 - 12 In, an intelligent construction system for the climbing and circulating formwork of a cylindrical structure includes an integrated mold and track device 8, an outer mold 18, and a multi-layer construction platform 1. A plurality of integrated mold and track devices 8 and a plurality of outer molds 18 form the outer mold structure of the overall surrounding cylindrical structure. The integrated mold and track device 8 is fixedly connected to the anchor cone 7 embedded in the pouring section 6 by bolts. The multi-layer construction platform 1 is vertically slidably connected to the integrated mold and track device 8 through the climbing device 11 to drive the multi-layer construction platform 1 to climb; that is, the self-climbing of the multi-layer construction platform 1 is achieved by operating the climbing device 11 to climb vertically along a plurality of integrated mold and track devices 8.

[0046] Multiple integrated formwork and track devices 8 and multiple outer formworks 18 are divided into at least three sections from top to bottom. The formwork cycle is achieved by lifting the formwork and track integrated device 8 and the outer formwork 18 at the bottom to the top. Preferably, in this example, the formwork and track integrated device 8 and the outer formwork 18 have a height of 9 meters in total, with each section being 3 meters. The formwork and track integrated device 8 and the outer formwork 18 at the bottommost section also serve as the foundation of the entire formwork construction system. The middle section is in the state of formwork curing, and the top section is in the state of steel bar processing and pouring construction.

[0047] The preferred solution is as follows Figure 1 , Figure 8 In the figure, the outer formworks 18 of each section from top to bottom are connected by a girth member 22; the position of the outer formwork 18 is restricted by the girth member 22. In the preferred solution, a plurality of rotatable tipping struts 109 are provided between the multi-layer construction platform 1 and the outer formwork 18. Specifically, the tipping strut 109 is connected to the inner edge of the multi-layer construction platform 1 through a pivot pin. A limiting mechanism, such as a limiting block, is provided on the tipping strut 109. When the tipping strut 109 is lowered, the tipping strut 109 is in a horizontal state and abuts against the girth member 22. An adjustable screw rod is provided on the tipping strut 109, and the adjustable screw rod abuts against the back of the girth member 22. Through the structure of the tipping strut 109 and the adjustable screw rod, the spatial position of the girth member 22 can be accurately adjusted, and then the position of the outer formwork 18 can be adjusted. And the tipping strut 109 provides sufficient supporting force for the outer formwork 18 to overcome the extrusion of the concrete on the outer formwork 18.

[0048] As Figure 19 As shown in the figure, the integrated formwork and track device 8 includes a vertically arranged formwork part, and the formwork part is directly attached to the surface of the pouring section 6, that is, directly attached to the surface of the concrete, constituting the formwork for concrete pouring, and is directly fixedly connected to the anchor cone 7 through bolts, with a better stress structure. A vertically arranged climbing track 12 is provided on the back of the formwork part. Preferably, the cross-section of the climbing track 12 is in a "T" shape structure, and the climbing device 11 is slidably connected to the climbing track 12; As Figure 19 As shown in the figure, the integrated formwork and track devices 8 of each section from top to bottom are connected to each other through a connecting flange 39 provided on the back of the formwork part. The connecting flange 39 only extends from the formwork part to the middle position in the direction of the climbing track. The connecting flange 39 extends to both sides, and a plurality of bolt holes are provided on the connecting flange 39. There is no connecting flange at the position of the climbing track 12 to avoid interference with the trolley 9 and the hook member 10. The integrated formwork and track devices 8 of the upper and lower sections are connected together through bolts passing through the connecting flange 39.

[0049] The preferred solution is as Figure 11Among them, the structure of the climbing device 11 is as follows: It includes a hook member 10, which is used to hang on the pin on the side of the climbing rail 12. Preferably, the hook member 10 is fixedly connected to the multi-layer construction platform 1. The hook member 10 is also connected to the first rail clamp 111. The first rail clamp 111 is connected to the climbing cylinder 112. The climbing cylinder 112 is connected to the second rail clamp 113. A locking device 114 is provided on the first rail clamp 111 and the second rail clamp 113. Preferably, the locking device 114 adopts a cam mechanism or a wedge mechanism. By turning the handle, the cam mechanism rotates, or by turning the handle, the wedge mechanism swings, which is used to lock or release the climbing rail 12. The process of climbing is as follows: First, lock the second rail clamp 113 and release the first rail clamp 111, so that the piston rod of the climbing cylinder 112 extends. The first rail clamp 111 moves upward and drives the hook member 10 upward until the hook member 10 hangs on an upper pin. Then lock the first rail clamp 111, release the second rail clamp 113, and the piston rod of the climbing cylinder 112 retracts. The second rail clamp 113 moves upward. Repeat the above climbing process, and the multi-layer construction platform 1 can be climbed upward. The rail clamp belongs to the components of the prior art.

[0050] As Figure 1 Among them, a pulley 9 is also provided on the multi-layer construction platform 1. The pulley 9 is connected to the climbing rail 12. The pulley 9 is provided with two groups of rollers, which are respectively located on both sides of the climbing rail 12. Each group of rollers has at least two. The rollers clamp the flange of the "T" - shaped structure of the climbing rail 12, which is used to provide guidance for the climbing of the multi-layer construction platform 1 and prevent the multi-layer construction platform 1 from deforming during the climbing process.

[0051] The preferred solution is as Figure 1 Among them, the multi-layer construction platform 1 is provided with two layers of steel bar platforms, two layers of pouring platforms, a climbing platform 105 and a form removal and curing platform 106 from top to bottom; that is, from top to bottom are the first steel bar platform 101, the second steel bar platform 102, the first pouring platform 103, the second pouring platform 104, the climbing platform 105, and the form removal and curing platform 106. The first steel bar platform 101 and the second steel bar platform 102 are used for installing the segment steel bar cage 16, connecting longitudinal bars and other operations. The first pouring platform 103 and the second pouring platform 104 are used for formwork erection, pouring, vibration and other work. The climbing platform 105 is used to operate the climbing of the multi-layer construction platform 1. The form removal and curing platform 106 is provided with a curing device 19, which is used to cure the poured section 6 after form removal. The curing device 19 adopts a section of annular water pipe, and spray holes are provided on the annular water pipe. The poured section 6 is cured by continuous spraying.

[0052] As Figure 1 Among them, the multi-layer construction platform 1 adopts the structure of a support frame 108, and a walking passage 107 is provided on each layer of the platform; because of the better stress structure of the multi-layer construction platform 1 of the present invention, there is no need to set up the structure of a tripod.

[0053] As shown Figure 1 in the figure, a cantilever beam 3 with its end extending out between the multi-layer construction platform 1 and the columnar structure is provided at the top of the multi-layer construction platform 1. A suspended track 2 is provided on the cantilever beam 3 through rollers, and the suspended track 2 can slide along the length direction of the cantilever beam 3. In this example, the suspended track 2 is arranged in multiple sections along the annular multi-layer construction platform 1. Preferably, as shown Figure 8 in the figure, each broken line is set as one section, and the suspended track 2 along the multi-layer construction platform 1 is set as 6 sections. Each section of the suspended track 2 is suspended on at least two cantilever beams 3 through rollers. A lifting device 4 is provided on the suspended track 2 through rollers, and the lifting device 4 can slide along the length direction of the suspended track 2. The lifting device 4 is provided with an electric lifting mechanism 17. Optionally, as shown Figure 20 in the figure, the electric lifting mechanism 17 adopts an electric hoist. The lifting device 4 is used to assist in lifting the mold-rail integrated device 8 and the outer mold 18. As shown Figure 8 in the figure, the mold-rail integrated device 8 can be lifted by a single lifting device 4. The outer mold 18 needs to be lifted jointly by at least two lifting devices 4. Moreover, each lifting device 4 is located on a different suspended track 2 to ensure safety. During the process of lifting the lifting device 4, it is necessary to avoid the position where the multi-layer construction platform 1 is connected to the mold-rail integrated device 8, otherwise major safety accidents may occur due to interference.

[0054] The preferred solution is as follows Figure 20 in the figure, a corner guard 41 is also provided. The corner guard 41 is used to be placed at the edges of the mold-rail integrated device 8 and the outer mold 18. A travel switch 43 is provided at the top of the corner guard 41, and ultrasonic distance sensors 42 are provided on both sides of the corner guard 41. The travel switch 43 is used to control the lifting height, and the ultrasonic distance sensors 42 are used to detect interference during the lifting process; the corner guard 41 is made of foamed polyurethane material and is sleeved on the top corners of the mold-rail integrated device 8 and the outer mold 18. The ultrasonic distance sensors 42 preferably adopt RCWL-1670 waterproof transceiver-separated ultrasonic distance measurement modules, and cooperate with Zigbee or Wi-Fi modules to achieve wireless communication, and only consume 1.5 uA current when powered by 3.3V. The distance between the ultrasonic distance sensors 42 and the interference structure is detected, including the distance between other outer molds 18 and the multi-layer construction platform 1, to ensure safety. The specific control method is as follows System initialization, hardware connection: Connect the TX echo signal and RX trigger signal of each RCWL-1670 module to the controller respectively. In this example, a wireless connection is used to connect to the PLC. The power supply is connected to 3 - 5V, and GND is grounded. Software initialization: Set a timer to measure the round-trip time of ultrasonic waves. Define the safety distance threshold. In this example, the safety distance Safe_Distance is set to 10 cm. Initialize the motion control module of the hoisting equipment, such as the electric hoist of the hoisting device 4. Start distance measurement: The controller sends a 10 μs high-level trigger signal to the RX pin to activate ultrasonic wave emission. The ultrasonic module emits a 40 kHz pulse signal and waits to receive the reflected signal. Measure the time difference: When the high level is detected at the TX pin, start the timer to record the time. When the TX pin returns to the low level, stop the timer and calculate the total time t. Calculate the distance based on the signal flight time: Calculate the current distance according to the formula Distance = (C × t) / 2, where C is the ultrasonic wave speed, with a value of approximately 340 m / s. Distance judgment: If Distance < Safe_Distance, such as 50 cm, enter the obstacle avoidance mode. If Distance >= Safe_Distance, continue normal hoisting. Obstacle avoidance operation: Pause hoisting: Immediately stop the vertical movement of components such as the outer mold 18 or the mold rail integrated device 8. Adjust the path: Offset in the front, back, left, and right directions and rescan the surrounding environment. Preferably, compare the distance Distance parameters detected by the ultrasonic rangefinders 42 in each direction and select the direction with a smaller distance for offset. Preferably, reduce the hoisting speed and gradually approach the obstacle until the safety distance is restored. Or alarm prompt: Trigger the buzzer or LED warning to remind the on-site construction personnel to intervene manually. Preferably, adopt an exception handling and fault tolerance mechanism: 1. Multi-point ranging verification: Continuously measure multiple times, take the minimum value or average value to reduce errors. 2. If the measurement results fluctuate greatly, for example, due to irregular surface reflection, extend the measurement interval or trigger a manual inspection. 3. Blind area processing: If the obstacle is within the 2 cm blind area, that is, the minimum detection distance of the RCWL-1670, it is directly determined as a dangerous state. 4. Timeout processing: If no echo signal is received, it is determined as a timeout, and it is assumed that the obstacle is too far away or there is an obstruction, and manual confirmation is required.

[0055] such as Figure 8In it, a vertical laser collimator 20 is provided on the perimeter form 22 of each section. The laser collimator 20 is used to detect the perpendicularity error of the perimeter form 22. Preferably, a vertical base seat is provided on the perimeter form 22. The base seat has a vertical surface, and the laser collimator 20 is installed on the vertical surface. A target is provided on the ground. After calibration, during the subsequent cycle of the laser collimator 20, it needs to be aligned with the corresponding target. It should be noted that the targets corresponding to the laser collimators 20 on the three sections of the perimeter form 22 are staggered from each other on the plane. The perimeter form 22 in this example is made of rectangular steel pipes. The perimeter form 22 is fixedly connected to the outer mold 18 through an "X"-shaped connecting piece.
