Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a temperature-adaptive connector for an ultra-kilometer-class jacking steel beam and a construction method thereof. Background Art

[0002] During the continuous jacking construction of the steel main beams of super-kilometer-class bridges, due to the long jacking construction period, the daily temperature difference between day and night is large during the entire jacking period, and the temperature sensitivity of the steel beam is stronger than that of concrete. The long-distance steel beam expands and contracts greatly under the influence of sunlight temperature. If the temperature effect of the steel beam is not released, a large horizontal force will be generated on the supporting structure, which will affect the safety of the main structure (including steel beams and bridge piers, etc.) and there is a great risk of overturning. Therefore, a temperature-adaptive connector for super-kilometer-class jacking steel beams and a construction method thereof are needed. Summary of the Invention

[0003] Based on the technical problem that during the continuous jacking construction of the existing super-kilometer-class bridge steel main beams, the long-distance steel beams expand and contract greatly under the influence of sunlight temperature. If the temperature effect of the steel beams is not released, a large horizontal force will be generated on the supporting structure, which will affect the safety of the main structure and there is a large overturning risk, the present invention proposes a super-kilometer-class jacking steel beam temperature adaptive connector and a construction method thereof.

[0004] The present invention proposes a super-kilometer-level temperature-adaptive connector for jacking steel beams, which includes a remote monitoring platform for monitoring and controlling the temperature-adaptive connection of jacking steel beams. The remote monitoring platform is data-connected to a finite element simulation module and a wireless communication module, and the wireless communication module is electrically connected to a controller.

[0005] The controller is electrically connected to a data acquisition module and an actuator respectively. The data acquisition module includes a temperature sensor and a light intensity sensor fixedly installed on the surface of the steel box girder. The temperature sensor and the light intensity sensor are both electrically connected to a data storage module.

[0006] The finite element simulation module is data-connected to a calculation module for calculating data collected by the light intensity sensor.

[0007] Preferably, the finite element simulation module is used to calculate the temperature-induced volume change of the steel box girder using the following formula: ΔV / V0=αΔT.

[0008] Here, ΔV / V0 represents the relative amount of volume change, α is the thermal expansion coefficient of the object, and ΔT represents the change in temperature.

[0009] Preferably, the actuator includes a first connecting frame and a second connecting frame fixedly connected to surfaces of two adjacent steel box girders.

[0010] A plurality of evenly distributed telescopic connection hydraulic cylinders are fixedly installed on the surface of the first connection frame by bolts. The telescopic connection hydraulic cylinders are electrically connected to the controller through a solenoid valve. The telescopic connection hydraulic cylinders are composed of a fixed cylinder body, a piston plate slidingly connected to the inner wall of the fixed cylinder body, a telescopic connection hydraulic rod fixedly connected to the surface of the piston plate, and a first oil chamber and a second oil chamber provided on the surface of the piston plate and the inner wall of the fixed cylinder body.

[0011] Preferably, one end of the telescopic connecting hydraulic rod passes through and extends to the surface of the fixed cylinder body, and one end of the telescopic connecting hydraulic rod is fixedly connected to a fixed connecting sleeve, and the surface of the fixed connecting sleeve is fixedly connected to the surface of the second connecting frame by bolts.

[0012] Preferably, the inner walls of the first oil chamber and the second oil chamber are fixedly connected with an oil inlet pipe and an oil return pipe, and the two oil inlet pipes and the two oil return pipes are connected to the hydraulic pump station.

[0013] Preferably, a control oil pipe is provided on the surface of the fixed cylinder body, the inner wall of the control oil pipe is fixedly connected to the inner walls of the first oil chamber and the second oil chamber respectively, and a sealed control solenoid valve is fixedly installed on the surface of the control oil pipe, and the sealed control solenoid valve is electrically connected to the controller.

[0014] Preferably, the inner walls of the first connecting frame and the second connecting frame are respectively hingedly mounted with a first supporting hydraulic cylinder and a second supporting hydraulic cylinder, and a plurality of the first supporting hydraulic cylinders and a plurality of the second supporting hydraulic cylinders are staggeredly distributed on the inner walls of the first connecting frame and the second connecting frame.

[0015] Preferably, the first supporting hydraulic cylinder and the second supporting hydraulic cylinder are both electrically connected to the controller through an electromagnetic valve, and the first supporting hydraulic cylinder includes a first supporting hydraulic rod, one end of which is hinged to the inner wall of the second connecting frame.

[0016] Preferably, the second supporting hydraulic cylinder includes a second supporting hydraulic rod, one end of which is hinged to the inner wall of the first connecting frame.

[0017] Preferably, a construction method for a super-kilometer-class temperature-adaptive connector for a jack-pushing steel beam comprises the following steps:

[0018] Step 1: First, based on the metal thermal conductivity of the steel box girder, data is entered into the finite element simulation module and simulation experiments are performed to calculate the relationship between temperature and volume change of the steel box girder.

[0019] Step 2: When pushing the steel box girder of the bridge, the steel box girders that need to be connected and pushed are connected through the actuator, and the temperature sensor and light intensity sensor in the data acquisition module are installed on the steel box girder. According to the actual shape and area of ​​the steel box girder, multiple temperature sensors and light intensity sensors are selected and installed on the steel box girder.

[0020] Step 3. When the steel box girder is pushed, the controller automatically controls the sealing control solenoid valve to close to prevent the hydraulic oil inside the first oil chamber and the second oil chamber from flowing to each other, thereby realizing the pushing of the steel box girder. When the pushing construction stops, the controller controls the sealing control solenoid valve to open. When the steel box girder expands and contracts due to temperature changes, the hydraulic oil inside the first oil chamber and the second oil chamber flows to each other, facilitating the free extension and retraction of the telescopic connection hydraulic rod, thereby preventing the steel box girder from being damaged by temperature changes on the telescopic connection hydraulic cylinder.

[0021] Step 4. During the jacking construction of the steel box girder, the temperature information of the steel box girder monitored by the light intensity sensor and the temperature sensor is fed back to the remote monitoring platform through the controller and the wireless communication module. The volume change of the steel box girder is simulated by the finite element simulation module and the calculation module, and fed back to the controller through the remote monitoring platform. The controller automatically controls the telescopic connection hydraulic cylinder and the first support hydraulic cylinder and the second support hydraulic cylinder to perform telescopic adjustment to adapt to the volume change of the steel box girder caused by the temperature.

[0022] The beneficial effects of the present invention are:

[0023] By setting up a controller that is electrically connected to a data acquisition module and an actuator, when in use, the temperature data of the steel box girder is collected by the data acquisition module and fed back to the remote monitoring platform. After analysis and processing by the finite element simulation module and the calculation module, the data is fed back to the remote monitoring platform and the controller. The controller automatically controls the actuator to adjust the connection spacing between the steel box girders, thereby solving the problem that during the continuous jacking construction of the existing super-kilometer-class bridge steel main beam, the long-distance steel beam expands and contracts greatly under the influence of sunlight temperature. If the temperature effect of the steel beam is not released, a large horizontal force will be generated on the supporting structure, which will affect the safety of the main structure and there is a large risk of overturning.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1

[0033] Reference Figures 1-6 A super-kilometer-level temperature-adaptive connector for jacking steel beams includes a remote monitoring platform 1 for monitoring and controlling the temperature-adaptive connection of jacking steel beams. The remote monitoring platform 1 is data-connected to a finite element simulation module 2 and a wireless communication module 3, and the wireless communication module 3 is electrically connected to a controller 4.

[0034] The controller 4 is electrically connected to a data acquisition module 5 and an actuator 6 , respectively. The data acquisition module 5 includes a temperature sensor 501 and a light intensity sensor 502 fixedly mounted on the surface of the steel box girder. The temperature sensor 501 and the light intensity sensor 502 are both electrically connected to a data storage module 7 .

[0035] When in use, the temperature of the steel box girder is collected through the temperature sensor 501 in the data acquisition module 5, and the collected temperature data is stored through the data storage module 7. At the same time, the collected temperature information data is fed back to the controller 4, and the controller 4 feeds back the temperature information collected by the data acquisition module 5 to the remote monitoring platform 1 through the wireless communication module 3.

[0036] The finite element simulation module 2 is data-connected to a calculation module 8 for calculating the data collected by the light intensity sensor 502 .

[0037] When in use, the collected data of the temperature sensor 501 and the light intensity sensor 502 are calculated by the calculation module 8, and the volume change of the steel box girder caused by the temperature change is simulated by the finite element simulation module 2, and then fed back to the remote monitoring platform 1 to provide remote control data support for the remote monitoring platform 1. Then, the remote monitoring platform 1 sends a control instruction to the controller 4 through the wireless communication module 3, and the controller 4 adjusts the connection between the steel box girder connections through the actuator 6.

[0038] Furthermore, when the steel box girder is pushed and adjusted, the surface temperature of the steel box girder will change with the illumination time and intensity under sunlight. In order to facilitate the rapid and accurate pushing and adjustment of the steel box girder, the temperature change of the steel box girder is calculated using the following formula:

[0039] T=(Ilb^2) / 4σ

[0040] Where T is the surface temperature of the steel box girder, I is the light intensity, l is the length of the steel box girder, b is the width of the steel box girder, and σ is the thermal conductivity of the metal.

[0041] When the temperature of the steel box girder is monitored, the initial temperature of the steel box girder can be obtained through the temperature sensor (501), and then by timing the illumination time, the final temperature can be calculated by the following formula: T=T0+Ilb^2t / 4*σ, where T0 is the initial temperature of the steel box girder and t is the illumination time.

[0042] Furthermore, when calculating and simulating the influence of light on the steel box girder through the calculation module (8) and the finite element simulation module (2), the sunshine angle calculation formula is added: θ=arcsin(cos(φs)cos(φh)cos(ωh)+sin(φs)sin(φh))

[0043] Among them, φs is the solar altitude angle, φh is the surface inclination angle, and ωh is the solar azimuth angle.

[0044] The method has the effect of eliminating the shadows caused by the angle of sunlight when adjusting the steel box girder, thereby affecting the change of the temperature of the steel box girder.

[0045] Furthermore, the finite element simulation module 2 is used to calculate the temperature-induced volume change of the steel box girder using the following formula: ΔV / V0=αΔT.

[0046] Here, ΔV / V0 represents the relative amount of volume change, α is the thermal expansion coefficient of the object, and ΔT represents the change in temperature.

[0047] The actuator 6 includes a first connection frame 601 and a second connection frame 602 fixedly connected to the surfaces of two adjacent steel box girders.

[0048] A plurality of evenly distributed telescopic connection hydraulic cylinders 603 are fixedly installed on the surface of the first connection frame 601 by bolts. The telescopic connection hydraulic cylinders 603 are electrically connected to the controller 4 through a solenoid valve. The telescopic connection hydraulic cylinders 603 are composed of a fixed cylinder body 6031, a piston plate 6032 slidingly connected to the inner wall of the fixed cylinder body 6031, a telescopic connection hydraulic rod 6033 fixedly connected to the surface of the piston plate 6032, and a first oil chamber 6034 and a second oil chamber 6035 provided on the surface of the piston plate 6032 and the inner wall of the fixed cylinder body 6031.

[0049] One end of the telescopic connecting hydraulic rod 6033 passes through and extends to the surface of the fixed cylinder body 6031. One end of the telescopic connecting hydraulic rod 6033 is fixedly connected to the fixed connecting sleeve 604. The surface of the fixed connecting sleeve 604 is fixedly connected to the surface of the second connecting frame 602 by bolts.

[0050] Furthermore, when in use, the telescopic connecting hydraulic cylinder 603 and the fixed connecting sleeve 604 are fixedly connected to the first connecting frame 601 and the second connecting frame 602 respectively by bolts, thereby facilitating the disassembly of the telescopic connecting hydraulic cylinder 603 and the fixed connecting sleeve 604 after the jacking of the bridge steel box girder is completed.

[0051] The inner walls of the first oil chamber 6034 and the second oil chamber 6035 are fixedly connected with an oil inlet pipe and an oil return pipe, and the two oil inlet pipes and the two oil return pipes are connected to the hydraulic pump station.

[0052] Furthermore, when in use, solenoid valves electrically connected to the controller 4 via cables are fixedly mounted on the surfaces of the oil inlet pipe and the oil return pipe.

[0053] A control oil pipe 605 is provided on the surface of the fixed cylinder body 6031, and the inner wall of the control oil pipe 605 is fixedly connected to the inner wall of the first oil chamber 6034 and the inner wall of the second oil chamber 6035 respectively. A sealed control solenoid valve 606 is fixedly installed on the surface of the control oil pipe 605, and the sealed control solenoid valve 606 is electrically connected to the controller 4.

[0054] During use, during the jacking process of the bridge, the sealing control solenoid valve 606 is controlled by the controller 4 to be closed to prevent the hydraulic oil inside the first oil chamber 6034 and the second oil chamber 6035 from flowing to each other, thereby realizing the jacking of the steel box girder. When the jacking construction stops, the controller 4 controls the sealing control solenoid valve 606 to open. When the steel box girder expands and contracts due to temperature changes, the hydraulic oil inside the first oil chamber 6034 and the second oil chamber 6035 circulates to each other, facilitating the free extension and retraction of the telescopic connection hydraulic rod 6033, thereby preventing the steel box girder from being damaged by temperature changes on the telescopic connection hydraulic cylinder 603.

[0055] The inner walls of the first connecting frame 601 and the second connecting frame 602 are respectively hingedly mounted with a first supporting hydraulic cylinder 607 and a second supporting hydraulic cylinder 608 . Multiple first supporting hydraulic cylinders 607 and multiple second supporting hydraulic cylinders 608 are staggeredly distributed on the inner walls of the first connecting frame 601 and the second connecting frame 602 .

[0056] The first supporting hydraulic cylinder 607 and the second supporting hydraulic cylinder 608 are both electrically connected to the controller 4 through solenoid valves. The first supporting hydraulic cylinder 607 includes a first supporting hydraulic rod 609 , one end of which is hinged to the inner wall of the second connecting frame 602 .

[0057] The second supporting hydraulic cylinder 608 includes a second supporting hydraulic rod 610 , one end of which is hinged to the inner wall of the first connecting frame 601 .

[0058] When in use, the first supporting hydraulic cylinder 607 and the second supporting hydraulic cylinder 608 support each other between the first connecting frame 601 and the second connecting frame 602 to ensure that the two adjacent steel box girders maintain a horizontal connection, and the first supporting hydraulic cylinder 607 and the second supporting hydraulic cylinder 608 are automatically controlled by the controller 4 to perform the supporting work. When the steel box girder expands and contracts due to temperature changes, the first supporting hydraulic rod 609 and the second supporting hydraulic rod 610 are automatically controlled to extend the length within the first supporting hydraulic cylinder 607 and the second supporting hydraulic cylinder 608 to ensure that the steel box girders remain horizontal, which is convenient for the jacking construction of the steel box girder.

[0059] By setting up a controller 4 electrically connected to the data acquisition module 5 and the actuator 6, when in use, the temperature data of the steel box girder is collected by the data acquisition module 5 and fed back to the remote monitoring platform 1. After being analyzed and processed by the finite element simulation module 2 and the calculation module 8, the data is fed back to the remote monitoring platform 1 and the controller 4. The controller 4 automatically controls the actuator 6 to adjust the connection spacing between the steel box girders, thereby solving the problem that during the continuous jacking construction of the existing super-kilometer-class bridge steel main beam, the long-distance steel beam has a large expansion and contraction amount under the influence of sunlight temperature. If the temperature effect of the steel beam is not released, a large horizontal force will be generated on the supporting structure, which will affect the safety of the main structure and there is a large risk of overturning.

[0060] Example 2

[0061] Reference Figures 1-6 A construction method for a temperature-adaptive connector for a super-kilometer-class jacking steel beam comprises the following steps:

[0062] Step 1: First, according to the metal thermal conductivity of the steel box girder, data is input and simulation experiments are performed on the finite element simulation module 2 to calculate the relationship between temperature and volume change of the steel box girder.

[0063] Step 2: When the steel box girders of the bridge are pushed, the steel box girders that need to be connected and pushed are connected through the actuator 6, and the temperature sensor 501 and the light intensity sensor 502 in the data acquisition module 5 are installed on the steel box girder. According to the actual shape and area of ​​the steel box girder, multiple temperature sensors 501 and light intensity sensors 502 are selected and installed on the steel box girder.

[0064] Step three, when the steel box girder is being pushed, the controller 4 automatically controls the sealing control solenoid valve 606 to close, preventing the hydraulic oil inside the first oil chamber 6034 and the second oil chamber 6035 from flowing to each other, thereby pushing the steel box girder. When the pushing construction stops, the controller 4 controls the sealing control solenoid valve 606 to open. When the steel box girder expands and contracts due to temperature changes, the hydraulic oil inside the first oil chamber 6034 and the second oil chamber 6035 circulates to each other, facilitating the free extension and retraction of the telescopic connection hydraulic rod 6033, thereby preventing the steel box girder from being damaged by temperature changes on the telescopic connection hydraulic cylinder 603.

[0065] Step 4: During the jacking construction of the steel box girder, the temperature information of the steel box girder monitored by the light intensity sensor 502 and the temperature sensor 501 is fed back to the remote monitoring platform 1 through the controller 4 and the wireless communication module 3. The volume change of the steel box girder is calculated and simulated by the finite element simulation module 2 and the calculation module 8, and fed back to the controller 4 through the remote monitoring platform 1. The controller 4 automatically controls the telescopic connection hydraulic cylinder 603 and the first support hydraulic cylinder 607 and the second support hydraulic cylinder 608 to perform telescopic adjustment to adapt to the volume change of the steel box girder caused by the temperature.

[0066] By setting up a controller 4 electrically connected to the data acquisition module 5 and the actuator 6, when in use, the temperature data of the steel box girder is collected by the data acquisition module 5 and fed back to the remote monitoring platform 1. After being analyzed and processed by the finite element simulation module 2 and the calculation module 8, the data is fed back to the remote monitoring platform 1 and the controller 4. The controller 4 automatically controls the actuator 6 to adjust the connection spacing between the steel box girders, thereby solving the problem that during the continuous jacking construction of the existing super-kilometer-class bridge steel main beam, the long-distance steel beam has a large expansion and contraction amount under the influence of sunlight temperature. If the temperature effect of the steel beam is not released, a large horizontal force will be generated on the supporting structure, which will affect the safety of the main structure and there is a large risk of overturning.
