Description

Technical Field

[0001] The invention relates to the technical field of steel structure roof installation, in particular to an intelligent adjustable method for a large-span arc-shaped steel structure curved roof. Background Art

[0002] With the rapid development of the national economy, there are more and more high-speed rail stations and large public building facilities in urban transportation. With the development of our society and the improvement of the level of civil engineering science and technology, more and more large-span spatial steel structures have appeared in our country. Due to its advantages such as large span, light weight and beautiful appearance, it is widely used. However, during the installation of large curved roofs, the deviation in component manufacturing, the influence of temporary auxiliary fixing components and the excess stress generated by prestressing will affect the precise installation of the device. In addition, after the existing supports are installed, there are problems of stress deformation during long-term use, which often require manual replacement or adjustment at high altitude, and even the entire system cannot be disassembled because of the inability to adjust. Therefore, the problem of installing the outer panel of the curved roof of the large-span curved steel structure is solved, ensuring the progress of the steel structure roof construction and the convenience of subsequent operation and maintenance. Summary of the Invention

[0003] In order to overcome the difficulty of installing the outer panels of large-span curved steel structure roofs, the present invention provides an intelligent adjustable method for steel structure curved roofs, which can effectively adjust the supports and is simple, easy to operate and low in cost.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] An intelligent adjustable method for a steel structure curved roof comprises the following steps:

[0006] 1) Determine component parameters

[0007] Based on the size of the roof panels, determine the length and levelness of the connecting rods;

[0008] 2) Installation of steel components

[0009] Before installing the support nodes, the steel components of the building need to be installed;

[0010] 3) Device assembly

[0011] Four nodes are set up at the four corners below the roof panel, and node prisms are set below the nodes. The two ends of the connecting rod are hinged to the connection nodes and the connecting parts respectively; one end of the force transmission rod is spherical and rotatably built into the upper ball joint, and the other end of the force transmission rod is fixedly connected to the force transmission rod magnet. The force transmission rod magnet is built into the moving space of the lower ball joint. The lower half of the rod body is provided with a thread that matches the thread of the lower ball joint; the lower ball joint is placed in the hinge support, which is composed of two parts A and B and connected by screws. The hinge support is connected to the keel through the fixing plates distributed at its four corners; each component is assembled in sequence;

[0012] 4) Device debugging

[0013] The instrument is assembled and debugged;

[0014] 5) Support fixation

[0015] Place the support on the keel, fix the fixing plate to the keel with bolts, connect the connecting rod to the node, and complete the connection and fixation of the device to the steel structure;

[0016] 6) Adjustment parameter acquisition

[0017] The positions of the support prism and node prism are measured and the monitoring data is transmitted to the control and analysis terminal. After analysis and comparison, the adjustment parameters are calculated and displayed;

[0018] 7) Height adjustment

[0019] Adjust the height until the roof panel reaches the correct position;

[0020] 8) Angle adjustment

[0021] The roof panel is adjusted to the design position by adjusting the support;

[0022] 9) Roof installation completed

[0023] Repeat steps 6) to 8) to complete the installation of the remaining roof panels of the entire equipment.

[0024] Furthermore, the method further comprises the following steps:

[0025] 10) Post-operation and maintenance

[0026] After the steel structure is installed, it will still deform to a certain extent under the influence of external forces during long-term use. Regular monitoring should be carried out. When the deformation exceeds the preset threshold, refer to steps 6) to 8) to adjust the deformed roof panel.

[0027] Furthermore, in step 2), the steel member includes a keel and a limiter, the node is passed through the cavity of the limiter, and the roof panel is temporarily placed on the limiter.

[0028] Furthermore, in step 3), the hinge support A and the hinge support B are relatively assembled, and the ball joint is placed. When placing, pay attention to the displacement correspondence between the magnet and the electromagnetic coil; use screws for preliminary fixing, the lower ball joint can rotate freely, and put in the configuration power supply.

[0029] The lower ball joint includes magnet A, magnet B, magnetic field isolation belt A, movable space and leveler. There are two magnets A and two magnets B, which are arranged opposite to each other. The magnetic field isolation belt A isolates the magnets from the movable space. The leveler is located on the upper part of the lower ball joint. There are two of them, which are arranged in both vertical and horizontal directions for viewing the situation of the leveler.

[0030] Furthermore, the hinge support A and hinge support B are connected by screws to form a hinge support, which includes motor A, motor B, motor C, electromagnetic coil A, electromagnetic coil B, electromagnetic coil C, rotating space A, rotating space B, rotating space C, a rotating shaft, signal transmitter B, a configuration power supply, a microprocessor, a coil, a support prism, a fixing plate, a magnetic field isolation strip B, and screws. Electromagnetic coil A is placed in rotating space A and connected to motor A via the rotating shaft. Electromagnetic coil B is placed in rotating space B and connected to motor B. Electromagnetic coil C is located in rotating space C and motor C is located at the bottom of the hinge support. The rotating shaft connects the motors and corresponding electromagnetic coils. There are two rotating spaces A and two rotating spaces B, arranged opposite each other in the hinge support; the configuration power supply is connected to the microprocessor, each motor, electromagnetic coil, and microprocessor via a coil; the support prism is located at the bottom of the hinge support; the magnetic field isolation strip B isolates the four electromagnetic coils. The control and analysis terminal is located on the ground and is equipped with signal transmitter A, a monitoring robot, and a display. The drone is located in the air and is equipped with signal transmitter C.

[0031] In step 4), the monitoring robot, the control and analysis terminal, and the drone are started to complete measurement, information transmission, and debugging of the lower ball joint rotation and the dowel rod lifting function. The verticality of the dowel rod is checked by a leveler to ensure its verticality;

[0032] In step 6), the positions of the support prism and the node prism are measured by the monitoring robot, and the monitoring data is transmitted to the control and analysis terminal. After analysis and comparison, the adjustment parameters are calculated and displayed on the display;

[0033] In the step 7), the control and analysis terminal transmits control information to the microprocessor through the signal transmitter A and the signal transmitter B. The microprocessor controls the configuration power supply to energize the electromagnetic coil C, and starts the motor C to drive the electromagnetic coil C to rotate clockwise. Due to the interaction of the magnetic field, the dowel rod magnet is driven to rotate clockwise, thereby causing the dowel rod to move upward, and the roof panel to move upward accordingly. During the process, the monitoring robot measures the position of the node prism in real time until the position is reached and the roof panel height adjustment is completed. The control and analysis terminal issues a stop rotation command, turns off the electromagnetic coil C and energizes the motor C.

[0034] In the step 8), first energize the electromagnetic coil B, start the motor B to drive the electromagnetic coil B to rotate 5° clockwise, and due to the interaction of the magnetic fields, the magnet B in the lower ball joint will be driven to rotate 5° clockwise, that is, the lower ball joint will rotate 5° clockwise in the cross section; then energize the electromagnetic coil A, start the motor A to drive the electromagnetic coil A to rotate 3° counterclockwise, and the magnet A in the lower ball joint will be driven to rotate 3° counterclockwise; the power supply of the electromagnetic coil B, motor B, electromagnetic coil A, and motor A is turned off by the control analysis terminal, and the angle adjustment of the support is completed; at this point, the support is adjusted so that the roof panel reaches the design position.

[0035] Preferably, in step 9), when a larger area of the site is used to transmit information through the signal transmitter C on the drone, the adjustment of all remaining roof panels is completed; considering the mutual influence during the installation process, it is necessary to review the positions of all roof panels of the equipment. When there are changes, steps 6) to 8) are completed for adjustment; tighten the screws to prevent the lower ball joint from rotating in the later stage, and complete the final fixation of the roof panel.

[0036] The configured power supply is located at the positive corner below the support and can be disassembled and replaced to provide power to each motor, electromagnetic coil and microprocessor; the microprocessor controls the switching of each motor and electromagnetic coil and the rotation of the motor.

[0037] The signal transmitter A and the signal transmitter B complete the information interaction between the transmission control analysis terminal and the microprocessor; the signal transmission is carried out through the signal transmitter C carried by the drone.

[0038] The center line of the connecting rod points to the center of the upper ball joint. The lengths of the connecting rods are the same. The upper ball joint is located at the center of the roof panel. The horizontal angle of the connecting rod is 30° by default.

[0039] The rotating shaft points to the center of the lower ball joint, ensuring that the lower ball joint rotates around the center of the ball, and the motor drives the electromagnetic coil at the corresponding position to rotate through the rotating shaft.

[0040] The node moves up and down in the cavity of the limiter, and the limiter is in the shape of a long strip.

[0041] The two ends of the connecting rod are respectively connected to the node and the connecting piece and are connected by a pin. There are four connecting pieces in total, which are evenly distributed on the upper ball joint and the positions correspond to the nodes.

[0042] The monitoring machine is used to measure the positions of the support prism and the node prism in real time, thereby determining the position parameters of the roof panel. The display is used to display the measured roof panel position and other parameters. The control and analysis terminal is used to process and analyze relevant data and then remotely control the adjustment of the support.

[0043] In the present invention, the movement of the upper ball joint can drive the nodes to move in conjunction, thereby adjusting the roof panel to complete the adjustment. The force transmission rod moves upward relative to the lower ball joint when rotating clockwise, and moves downward relative to the lower ball joint when rotating counterclockwise. The magnetic field isolation belt is mainly used to isolate the mutual influence between the magnet and the electromagnetic coil to ensure the movement and rotation effect of the lower ball joint. The moving space reserves space for the force transmission rod magnet to move up and down and rotate horizontally. When the tightening screw is tightened, the lower ball joint is fixed in the hinge support; when the tightening screw is loosened, the lower ball joint can rotate in the hinge support.

[0044] The beneficial effects of the present invention are mainly manifested in:

[0045] (1) Efficient adjustment method combining movement and rotation. The rotation and lifting of the upper ball joint are controlled by electromagnetic linkage, completing three-dimensional adjustment. Since the two sides of the roof panel move in opposite directions during rotation adjustment, it is more efficient than two unidirectional movements.

[0046] (2) Integrated multi-point intelligent operation. Through the monitoring robot, control and analysis terminal and built-in wireless network, information and data are exchanged, completing the adjustment mode from monitoring, analysis, adjustment and review. When necessary, it can be switched through drones to increase the control range and form a one-to-many control network.

[0047] (3) Environmentally friendly, safe and reliable. The hinged support can be adjusted and recycled, and reused in other building components. It is not a disposable component. The adjustment parameters are adjusted in real time based on actual measurements and design requirements, avoiding the need for personnel to climb high to operate and improving safety.

[0060] 1) Determine component parameters

[0061] Based on the size of the roof panels, determine the length and levelness of the connecting rods;

[0062] 2) Installation of steel components

[0063] Before installing the support nodes, the steel components of the building need to be installed;

[0064] 3) Device assembly

The connecting rod 3 connects the node 2 and the connecting piece 4 and is connected by a pin. There are four connecting pieces 4 in total, which are evenly distributed on the upper ball joint 5 and their positions correspond to the node 2. One end of the force transmission rod 6 is spherical and built into the upper ball joint 5, where it can rotate freely. The other end is fixedly connected to the force transmission rod magnet 22.

[0078] Furthermore, the method further comprises the following steps:

[0079] 10) Post-operation and maintenance

[0080] After the steel structure is installed, it will still deform to a certain extent under the influence of external forces during long-term use. Regular monitoring should be carried out. When the deformation exceeds the preset threshold, refer to steps 6) to 8) to adjust the deformed roof panel.

[0081] Furthermore, in step 2), the steel member includes a keel and a limiter, the node is passed through the cavity of the limiter, and the roof panel is temporarily placed on the limiter.

[0082] Furthermore, in step 3), the hinge support A and the hinge support B are relatively assembled, and the ball joint is placed. When placing, pay attention to the displacement correspondence between the magnet and the electromagnetic coil; use screws for preliminary fixing, the lower ball joint can rotate freely, and put in the configuration power supply.

[0083] Furthermore, the lower spherical joint 7 includes magnet A 201, magnet B 202, magnetic field isolation strip A 211, movable space 23, and a leveler 30. Two magnets A 201 and two magnets B 202 are arranged opposite each other, and magnetic field isolation strip A 211 separates each magnet from movable space 23. Two levelers 30 are located on the upper portion of the lower spherical joint 7, arranged in both vertical and horizontal directions, for monitoring the leveler status.

[0084] Hinge support A 81 and hinge support B 82 are connected by screws 24 to form hinge support 8, which includes motor A 101, motor B 102, motor C 103, electromagnetic coil A 111, electromagnetic coil B 112, electromagnetic coil C 113, rotating space A 121, rotating space B 122, rotating space C 123, rotating shaft 13, signal transmitter B 142, configuration power supply 15, microprocessor 16, coil 17, support prism 181, fixing plate 19, magnetic field isolation strip B 212, and screws 24. Electromagnetic coil A 111 is placed in rotating space A 121 and connected to motor A 101 via the rotating shaft. Electromagnetic coil B 112 is placed in rotating space B 122 and connected to motor B 102. Electromagnetic coil C 113 is located in rotating space C 123 and motor C 103 is located at the bottom of hinge support 8. Rotating shaft 13 connects the motors and the corresponding electromagnetic coils. Two rotating spaces A 121 and two rotating spaces B 122 are arranged opposite each other in the hinge support 8. A power supply 15 is connected to the microprocessor 16, the motors, the electromagnetic coils, and the microprocessor 16 via a coil 17. A support prism 181 is located at the bottom of the hinge support 8. A magnetic field isolation strip B 212 isolates the four electromagnetic coils. A control and analysis terminal 27 is located on the ground and houses a signal transmitter A 141, a monitoring robot 25, and a display 26. A drone 28 is located in the air and is equipped with a signal transmitter C 143.

[0085] The power supply 15 is located at the positive corner below the support and can be disassembled and replaced to provide power to each motor, electromagnetic coil and microprocessor 16. The microprocessor 16 controls the switches of each motor and electromagnetic coil and the rotation of the motor.

[0086] Signal transmitter A 141 and signal transmitter B 142 complete the information exchange between the transmission control analysis terminal 27 and the microprocessor 16. When the site is large, in order to avoid signal attenuation, signal transmission can be carried out through the signal transmitter C 143 carried by the drone 28.

[0087] The movement of the upper spherical joint 5 can drive the node 2 to move in conjunction, thereby adjusting the roof panel 1 to complete the adjustment.

[0088] The force transmission rod 6 moves upward relative to the lower ball joint 7 when it rotates clockwise, and moves downward relative to the lower ball joint 7 when it rotates counterclockwise.

[0089] The centerline of the connecting rod 3 points to the center of the sphere of the upper spherical joint 5. The lengths of the connecting rods are the same, and the upper spherical joint 5 is located at the center of the roof panel 1. The horizontal angle of the connecting rod 3 is 30° by default.

[0090] The rotating shaft 13 points to the center of the ball of the lower ball joint 7, ensuring that the lower ball joint 7 rotates around the center of the ball. The motor drives the electromagnetic coil at the corresponding position to rotate through the rotating shaft 13.

[0091] The magnetic field isolation zone is mainly used to isolate the mutual influence between the magnet and the electromagnetic coil, thereby ensuring the movement and rotation effect of the lower ball joint 7.

[0092] The moving space 23 is reserved for the dowel rod magnet 22 to move up and down and rotate horizontally.

[0093] When the tightening screw 24 is tightened, the lower ball joint 7 is fixed in the hinge support 8 ; when the tightening screw 24 is loosened, the lower ball joint 7 can rotate in the hinge support 8 .

[0094] The monitoring robot 25 can measure the positions of the support prism 181 and the node prism 182 in real time, thereby determining the position parameters of the roof panel.

[0095] The display 26 mainly displays the measured roof panel position and other parameters. The control and analysis terminal 27 processes and analyzes the relevant data and then remotely controls the adjustment of the support.

[0096] The limiter 29 is in the shape of a long strip, and has a hole with a set aperture, and the node 2 can move up and down in the hole.

[0097] A steel-structured station is arranged in an east-west orientation on a main highway. From top to bottom, the station consists of a platform level, a lower platform level, and a concourse level. The station's steel structure reaches a height of 23.35 meters at its highest point, spans 33.4 meters, and has a total length of 108 meters. The cantilevered spaces at both ends of the station have hyperbolic arc dimensions (length × width × height) of 34.7 meters × 24 meters × 12.7 meters. They are constructed of D402 × 14 round steel pipes, and the roof measures 2 meters × 2 meters. The magnetic field isolation strips are made of 1mm thick PVC, and the monitoring robot uses a Leica sensor.

[0098] The method for implementing the intelligent adjustable support device for the curved steel roof of this embodiment includes the following steps:

[0099] 1) Determine component parameters

[0100] The length of connecting rod 3 is determined according to the actual project requirements. Since the roof panel size is 2m×2m, the horizontal angle of the connecting rod is 30°. Since the length of connecting rod 3 is 1.732m, it is rounded up to 1.8m.

[0101] 2) Installation of steel components

[0102] Before installing the support node, it is necessary to install the main steel components of the building, including the keel 9 and the limiter 29. Pass the node 2 through the hole of the limiter 29 and temporarily place the roof panel 1 on the limiter 29.

[0103] 3) Device assembly

[0104] Assemble the components in order. Assemble hinge supports A and B relative to each other, and place the ball hinge 7. Ensure the magnet and electromagnetic coil are aligned. Use screws 24 for initial securement. Ensure the lower ball hinge 7 is free to rotate, and then install the power supply 15.

[0105] 4) Device debugging

[0106] After the instrument is assembled, the monitoring robot 25, the control and analysis terminal 27 and the drone 28 are started to complete the debugging of the measurement, information transmission, the rotation of the lower ball joint 7 and the lifting and lowering of the force transmission rod 6. The verticality of the force transmission rod 6 is checked by the leveler 30 to ensure its verticality.

[0107] 5) Support fixation

[0108] Place the support 8 on the keel 9 and fix the fixing plate 19 to the keel 9 with bolts. Connect the connecting rod 3 to the node 2 to complete the connection and fixation of the device to the steel structure.

[0109] 6) Adjustment parameter acquisition

[0110] Monitoring robot 25 measures the positions of support prism 181 and node prism 182 and transmits the monitored data to control and analysis terminal 27. After analysis and comparison, adjustment parameters are calculated and displayed on display 26. In this case, the adjustment parameters are a 1cm rise, a 5° clockwise rotation of the cross section, and a 3° counterclockwise rotation of the longitudinal section.

[0111] 7) Height adjustment

[0112] The control and analysis terminal 27 transmits control information to the microprocessor 16 via signal transmitters A and B. The microprocessor 16 controls the configuration power supply 15 to energize the electromagnetic coil C 113, starting the motor C 103 and causing the electromagnetic coil C 113 to rotate clockwise. Due to the interaction of the magnetic fields, this causes the dowel rod magnet 22 to rotate clockwise, which in turn causes the dowel rod 6 to move upward, and the roof panel 1 to move upward accordingly. During this process, the monitoring robot 25 measures the position of the node prism 182 in real time until it reaches the desired position, completing the roof panel height adjustment. The control and analysis terminal 27 issues a stop command, deactivating the electromagnetic coil C 113 and powering the motor C 103.

[0113] 8) Angle adjustment

[0114] First, energize electromagnetic coil B 112 and start motor B 102, causing electromagnetic coil B 112 to rotate 5° clockwise. Due to the interaction of the magnetic fields, this in turn causes magnet B 202 in the lower spherical joint 7 to rotate 5° clockwise, effectively rotating the lower spherical joint 7 5° clockwise in cross-section. Then, energize electromagnetic coil A 111 and start motor A 101, causing electromagnetic coil A 111 to rotate 3° counterclockwise, which in turn causes magnet A 201 in the lower spherical joint 7 to rotate 3° counterclockwise. Control and analysis terminal 27 then shuts off electromagnetic coil B 112, motor B 102, electromagnetic coil A 111, and motor A 101, completing the angle adjustment of the support. At this point, the support has been adjusted to position the roof panel 1 to the desired design.

[0115] 9) Roof installation completed

[0116] Refer to steps 6-8 to complete the installation of the remaining roof panels throughout the station. For larger areas, the signal transmitter C143 on drone 28 can be used to transmit information and adjust all remaining roof panels. To account for any interactions during installation, the positions of all station roof panels need to be adjusted. If any changes occur, perform adjustments using steps 6-8. Tighten screws 24 to prevent the lower ball joint 7 from rotating later, completing the final fixation of the roof panels.

[0117] 10) Post-operation and maintenance

[0118] After the steel structure is installed, it will still deform to a certain extent under the influence of external forces during long-term use. The monitoring robot 25 performs regular monitoring. When the deformation is large, refer to steps 6) to 8) to adjust the deformed roof panel.

The scope of protection of the present invention should not be considered limited to the specific embodiments described in these embodiments.
