Description

Technical Field

[0001] This application relates to the field of road and bridge technology, for example to a prefabricated tensioned steel beam and its control method, and a prefabricated tensioned steel beam. Background Technology

[0002] Bridge beams, such as those for highways or pedestrian overpasses, use rolled steel sections with specific cross-sectional shapes, or assembled beams or box girders made by assembling these steel sections with joint materials. These beams are erected on piers or abutments constructed at intervals, serving to support the fixed weight of the concrete structures poured on them and the road structures paved on the concrete structures, while also supporting the variable weight of vehicles or pedestrians moving on the road. Therefore, the various forms of forces acting on the bridge beams must be considered. In particular, if the central part between the piers bends downward due to vertical loads, there is a possibility of the entire bridge collapsing.

[0003] Currently, in order to improve the structural strength of steel beams, the traditional methods involve reinforcing the material itself by increasing its thickness or by welding stiffeners to areas with concentrated loads. However, these methods not only increase material costs but also increase weight and volume, making them difficult to handle during transportation and construction. Furthermore, since increasing the material thickness or welding stiffeners provides only a limited increase in strength, it is necessary to shorten the beam length to improve structural strength when it needs to withstand large loads. In such cases, it is necessary to increase the number of piers, which leads to a significant increase in construction costs and construction difficulty. Therefore, the current methods are not suitable for constructing long-span bridges.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Traditional methods of strengthening steel beam structures by increasing the thickness of the material itself or by welding reinforcing ribs have significant limitations and are not suitable for erecting long-span bridges.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a prefabricated tensioned steel beam and its control method. The prefabricated tensioned steel beam breaks through the limitations of traditional methods that increase the thickness of the material itself or weld reinforcing ribs to strengthen the steel beam structure. It helps to reduce the thickness of the steel beam body and the material cost, reduce the volume and weight of the steel beam body, and make it easier to transport and construct the steel beam body. At the same time, the prefabricated tensioned steel beam is suitable for erecting large-span bridges, which can effectively reduce the bridge erection cost and the construction difficulty of bridge erection.

[0009] In some embodiments, a prefabricated tensioned steel beam includes: a steel beam body, a tensioning assembly, a detection assembly, and a controller assembly. The steel beam body is generally elongated, and a supporting steel plate is provided at the bottom of the steel beam body, wherein the supporting steel plate is perpendicular to the steel beam body; the tensioning assembly includes a tensioning drive unit and a tensioning rope, the tensioning drive units are arranged in pairs, and the pairs of tensioning drive units are respectively located at both ends of the steel beam body along its length; one end of the tensioning rope is connected to one of the tensioning drive units, and the other end passes through the supporting steel plate and is connected to the other tensioning drive unit, wherein the pairs of tensioning drive units provide tensioning forces in opposite directions to the tensioning rope; the detection assembly is disposed on the steel beam body and is used to detect the weight borne by the steel beam body; the controller assembly is connected to both the detection assembly and the tensioning drive unit, and the controller assembly is used to control the tensioning drive unit to pull the tensioning rope and adjust the tension of the tensioning rope according to the weight borne by the steel beam body.

[0010] In some embodiments, a control method for prefabricated tensioned steel beams includes:

[0011] Obtain the load-bearing capacity of the steel beam body;

[0012] Based on the relationship between the load-bearing weight of the steel beam and the contraction length of the tension rope, the tensioning drive unit is controlled to pull the tension rope to contract according to the contraction length.

[0013] The prefabricated tensioned steel beam and its control method provided in this disclosure can achieve the following technical effects:

[0014] When the detection component detects an external force acting on the steel beam body to bear its weight, the controller component controls the paired tensioning drive units to provide opposite traction forces to the tensioning ropes, adjusting the tension of the tensioning ropes and further enhancing their tension. Thus, the tensioning ropes, through the supporting steel plates, provide upward support to the steel beam body to counteract the external force acting on it, preventing the steel beam body from bending downwards under external force, improving its resistance to bending, enhancing the structural strength and stability of the steel beam body, and ensuring the safety of bridge erection. This application's prefabricated tensioned steel beam breaks through the limitations of traditional methods that increase the thickness of the material itself or weld reinforcing ribs to strengthen the steel beam structure. It helps reduce the thickness and material cost of the steel beam body, reduces its volume and weight, and makes it easier to handle and construct. Furthermore, prefabricated tensioned steel beams are suitable for erecting large-span bridges, effectively reducing bridge erection costs and construction difficulty.

[0035] Combination Figure 1-2 As shown, this embodiment of the present disclosure provides a prefabricated tensioned steel beam, including: a steel beam body 100, a tensioning assembly 300, a detection assembly 400, and a controller assembly 500. The steel beam body 100 is generally elongated, and a supporting steel plate 200 is provided at the bottom of the steel beam body 100, wherein the supporting steel plate 200 is perpendicular to the steel beam body 100; the tensioning assembly 300 includes a tensioning drive unit 301 and a tensioning rope 302, the tensioning drive units 301 are arranged in pairs, and the pairs of tensioning drive units 301 are respectively arranged at both ends of the steel beam body 100 in the length direction; one end of the tensioning rope 302 is connected to one of the tensioning drive units 301, and the other end passes through the supporting steel plate 200 and is connected to the other. The tensioning drive unit 301, wherein the paired tensioning drive units 301 provide tensioning ropes 302 with opposite traction forces; the detection component 400 is disposed on the steel beam body 100 and is used to detect the weight borne by the steel beam body 100; the controller component 500 is connected to both the detection component 400 and the tensioning drive unit 301, and the controller component 500 is used to control the tensioning drive unit 301 to pull the tensioning ropes 302 and adjust the tension state of the tensioning ropes 302 according to the weight borne by the steel beam body 100.

[0036] Using the prefabricated tensioned steel beam provided in this embodiment, when the detection component 400 detects an external force acting on the steel beam body 100 causing it to bear weight, the controller component 500 controls the paired tensioning drive units 301 to provide opposite traction forces to the tension ropes 302, adjusting the tension state of the tension ropes 302 and further enhancing their tension. Thus, the tension ropes 302, through the support steel plate 200, can provide upward support to the steel beam body 100 to counteract the external force acting on the steel beam body 100, preventing the steel beam body 100 from being damaged by the external force. In cases of downward bending deformation, this method enhances the steel beam's resistance to bending, strengthens the structural strength and stability of the steel beam body 100, and ensures the safety of bridge erection. The prefabricated tensioned steel beam of this application breaks through the limitations of traditional methods that rely on increasing the thickness of the material itself or welding reinforcing ribs to strengthen the steel beam structure. It helps to reduce the thickness and material cost of the steel beam body 100, reduce the volume and weight of the steel beam body 100, and makes it easier to handle and construct the steel beam body 100. At the same time, the prefabricated tensioned steel beam is suitable for erecting large-span bridges, which can effectively reduce bridge erection costs and construction difficulties.

[0037] Understandably, the detection component 400 is a weight sensor, pressure sensor, etc. in the prior art, the tensioning drive unit 301 is a traction machine, drum drive machine, drive motor, etc. in the prior art, and the tensioning rope 302 is a steel wire rope formed by steel wire or multiple steel wires twisted together.

[0038] Optionally, the supporting steel plate 200 has a T-shaped structure and is located on the bottom side of the steel beam body 100, or on the side wall of the steel beam body 100 and protruding downwards. In this way, under the action of the tension rope 302 in a taut state, a more stable and upward supporting force can be provided to the steel beam body 100, preventing the steel beam body 100 from bending downwards under external forces, thereby effectively reducing the possibility of the bridge collapsing as a whole.

[0039] Optionally, multiple detection components 400 are provided, and these components are evenly distributed on the steel beam body 100. Each detection component 400 is used to detect the load-bearing weight at its corresponding location. This facilitates the acquisition of the load-bearing weight at multiple locations on the steel beam body 100, enabling the rapid and accurate determination of the location where the steel beam body 100 bears the maximum load. This allows for better control of the supporting steel plate 200 in conjunction with the tensioning component 300 to structurally strengthen the steel beam body 100, preventing bending deformation due to excessive load at a single location that could lead to the collapse of the entire bridge and thus better ensuring the overall safety of the bridge.

[0040] Optionally, the number of tensioning components 300 is determined by the width of the steel beam body 100. When only one tensioning component 300 is used, it is located on a central axis parallel to the length of the steel beam body 100. When multiple tensioning components 300 are used, they are arranged along the width of the steel beam body 100 and are parallel to each other. By determining the number of tensioning components 300 based on the width of the steel beam body 100, the number of components can be adapted to the structure of the steel beam body 100, thereby providing better and more comprehensive reinforcement of the overall structure of the steel beam body 100, ensuring its overall structural strength and stability.

[0041] Optionally, one tensioning component 300 is installed within one meter of the width of the steel beam body 100, and an additional tensioning component 300 is installed for every additional meter of width of the steel beam body 100. When more than two tensioning components 300 are installed, two of them are installed on the bottom sides of the steel beam body 100, while the remaining tensioning components 300 are evenly installed between the bottom sides of the steel beam body 100. This makes the installation of the tensioning components 300 on the steel beam body 100 more rational, allowing the tensioning components 300 to support and reinforce the steel beam body 100 from all directions, preventing bending deformation due to excessive weight at one location and thus avoiding the collapse of the entire bridge, ensuring the overall safety of the bridge.

[0042] Optionally, three tensioning components 300 are provided, two of which are installed on the bottom sides of the steel beam body 100, and the remaining one is installed on the central axis of the steel beam body 100. In this way, the sides and the middle of the steel beam body 100 can be supported and reinforced, thereby forming an overall reinforcement of the steel beam body 100.

[0043] Optionally, when multiple tensioning components 300 are provided, multiple tensioning ropes 302 are threaded onto the supporting steel plate 200. This ensures that each tensioning rope 302 can provide upward support to the steel beam body 100 through the supporting steel plate 200, and that each tensioning component 300 can provide support and reinforcement to the steel beam body 100. This better guarantees the overall structural strength of the steel beam body 100 and prevents localized bending of the steel beam body 100.

[0044] Optionally, the connection points of multiple tensioning components 300 and the supporting steel plate 200 are aligned on the same straight line. This effectively avoids the supporting steel plate 200 from being affected by reaction forces, ensuring that the force can be concentrated and transmitted to the steel beam body 100 through the supporting steel plate 200, thus providing more stable support for the steel beam body 100.

[0045] Optionally, the number and position of the supporting steel plates 200 are determined by the length of the steel beam body 100. When multiple supporting steel plates 200 are provided, they are evenly distributed along the length of the steel beam body 100. In this way, by evenly distributing the supporting steel plates 200 along the length of the steel beam body 100, the supporting steel plates 200 can better support and reinforce the entire steel beam body 100, preventing one end of the steel beam body 100 from bending due to stress, and ensuring the overall structural stability of the steel beam body 100.

[0046] In some other embodiments, optionally, when multiple tensioning components 300 and supporting steel plates 200 are provided, each tensioning component 300 corresponds to one supporting steel plate 200, and the tensioning rope 302 of each tensioning component 300 is threaded onto its corresponding supporting steel plate 200. In this way, since the load-bearing capacity at each location on the steel beam body 100 may differ, the use of one-to-one corresponding tensioning components 300 and supporting steel plates 200 allows for flexible handling of the stress conditions on the steel beam body 100, preventing local bending of the steel beam body 100 and ensuring the overall structural strength and stability.

[0047] like Figure 3-5 As shown, optionally, the steel beam body 100 is a long strip of T-shaped steel, I-shaped steel, rectangular steel plate, or an assembled steel beam structure formed by assembling one of T-shaped steel, I-shaped steel, and rectangular steel plates. In this way, existing T-shaped steel, I-shaped steel, and rectangular steel plates can be directly utilized to modify various structural steel sections in the prior art. The tensioning component 300 can be rationally installed on the existing steel sections to achieve the purpose of supporting and reinforcing the steel sections, thus eliminating the need to forge new steel sections, reducing forging difficulty and saving costs.

[0048] like Figure 3 As shown, optionally, when the steel beam body 100 is a T-shaped steel, the supporting steel plate 200 is set on the web of the T-shaped steel, and the tensioning assembly 300 is set on the corresponding two sides at the bottom of the vertical sidewall of the T-shaped steel. In this way, the installation of the tensioning assembly 300 is adapted to the structure of the T-shaped steel, thereby better supporting and reinforcing the T-shaped steel and ensuring the structural stability of the T-shaped steel.

[0049] like Figure 4-5As shown, optionally, when the steel beam body 100 is an I-beam, both the supporting steel plate 200 and the tensioning assembly 300 are located at the bottom of the I-beam, and the tensioning drive part 301 of the tensioning assembly 300 is located on both sides of the supporting steel plate 200, or both the supporting steel plate 200 and the tensioning assembly 300 are located in corresponding grooves of the I-beam, wherein the tensioning drive part 301 of the tensioning assembly 300 is located on the top sidewall of the groove, and the tensioning rope 302 passes through the bottom of the supporting steel plate 200. This makes the installation of the tensioning assembly 300 more adaptable to the structure of the I-beam, thereby better supporting and reinforcing the I-beam, ensuring the structural strength and stability of the I-beam.

[0050] Optionally, the tension rope 302, connected between the paired tension drive units 301 and passing through the support steel plate 200, has an arched structure on the lower side of the steel beam body 100. In this way, when the tension drive unit 301 stretches the tension rope 302, the tension rope 302 can stably provide a vertically upward supporting force to the steel beam body 100, which can effectively prevent the steel beam body 100 from bending downward.

[0051] Optionally, the supporting steel plate 200 can be movably connected to the steel beam body 100. This allows for more flexible installation of the supporting steel plate 200, making it easier to control the movement of the supporting steel plate 200 to address the stress on the steel beam body 100, thereby effectively preventing localized downward bending of the steel beam body 100 and ensuring the overall structural stability of the steel beam body 100.

[0052] Understandably, the supporting steel plate 200 and the steel beam body 100 are connected by an electric slide rail. The electric slide rail is existing technology, and its specific structure will not be described in detail here.

[0053] like Figure 6 As shown, optionally, the prefabricated tensioned steel beam also includes a warning component 600. The warning component 600 is installed on the steel beam body 100 and connected to the controller component 500. It is controlled by the controller component 500 to issue a warning message when the steel beam body 100 deforms or reaches its maximum load. Thus, when the steel beam body 100 deforms or reaches its maximum load, the warning component 600 issues a warning, not only alerting vehicles or pedestrians on the bridge to a safety hazard and prompting them to leave the bridge immediately, effectively ensuring personnel safety, but also sending the warning to maintenance personnel so that they can promptly repair the bridge, reducing the probability of serious accidents such as traffic accidents.

[0054] Optionally, the warning component 600 includes: an audible and visual alarm; and / or a remote alarm. The audible and visual alarm can emit both audible and visual alarm signals, using sound and various lights to warn vehicles or pedestrians on the bridge, reminding them to leave as soon as possible. The remote alarm connects to a network and can transmit data information remotely, enabling maintenance personnel to promptly perform bridge repairs.

[0055] It is worth noting that both audible and visual alarms and remote alarms are existing technologies that can be directly installed and used, which helps reduce costs.

[0056] Combination Figure 7 As shown in the embodiments of this disclosure, a control method for prefabricated tensioned steel beams is provided, including:

[0057] S01, obtain the load-bearing capacity of the steel beam body;

[0058] S02, based on the relationship between the load-bearing weight of the steel beam and the contraction length of the tension rope, control the tensioning drive unit to pull the tension rope to contract according to the contraction length.

[0059] The control method for prefabricated tensioned steel beams provided in this disclosure can more accurately control the contraction length of the tension rope by based on the correspondence between the load-bearing weight of the steel beam and the contraction length of the tension rope. This avoids both excessive support due to excessive contraction length affecting the structural stability of the steel beam and insufficient support for the steel beam. It can better and more flexibly respond to changes in the weight of the steel beam, achieving not only automatic control and higher efficiency, but also better support of the steel beam after contraction, preventing downward bending deformation and ensuring the structural strength and stability of the steel beam, thus contributing to improved bridge safety.

[0060] Optionally, the relationship between the load-bearing weight N of the steel beam and the contraction length L of the tension rope is shown in the table below:

[0061] Bearing weight N contraction length L N≤400kg L≤2cm 400kg<N≤800kg 2cm < L ≤ 4cm 800kg<N≤1200kg 4cm<L≤6cm 1200kg<N≤1600kg 6cm < L ≤ 8cm 1600kg<N 8cm<L≤10cm

[0062] It is worth noting that: because the tensioning rope is under tension because each of the paired tensioning drive parts pulls one end of the tensioning rope and causes it to coil, the tensioning rope is in a taut state. Therefore, the contraction length of the tensioning rope refers to the sum of the contraction lengths at both ends of the tensioning rope. For example, when the load N of the steel beam body is 400kg, if each of the paired tensioning drive parts pulls one end of the tensioning rope and contracts by 1cm, the sum of the contraction lengths of the tensioning rope pulled by the paired tensioning drive parts is 2cm; when the load N of the steel beam body is 800kg, if each of the paired tensioning drive parts pulls one end of the tensioning rope and contracts by 2cm, the sum of the contraction lengths of the tensioning rope pulled by the paired tensioning drive parts is 4cm.

[0063] Optionally, after obtaining the load-bearing capacity of the steel beam body, the method further includes: determining whether the load-bearing capacity of the steel beam body exceeds the limit weight; and issuing a warning message if the load-bearing capacity of the steel beam body exceeds the limit weight, where the limit weight is the maximum load-bearing capacity of the steel beam body. In this way, when the load-bearing capacity of the steel beam body reaches the limit value, a warning is issued, which not only alerts vehicles or pedestrians on the bridge to a safety hazard, reminding them to leave as soon as possible and effectively ensuring their safety, but also sends the warning to maintenance personnel so that they can promptly repair the bridge, reducing the probability of serious accidents such as traffic accidents.

[0064] Optionally, after obtaining the load-bearing capacity of the steel beam body, the process further includes: determining the target position on the steel beam body where the maximum load is borne; and controlling the movement of the support steel plate to the target position based on the target position. Since the position on the steel beam body bearing the maximum load is most prone to deformation, moving the support steel plate to the target position, after controlling the tension of the tension rope, allows the support steel plate to better provide upward support to the target position, preventing bending deformation due to the large load, thereby effectively ensuring the structural strength and stability of the steel beam body.

[0065] Optionally, after obtaining the load-bearing capacity of the steel beam body, the method further includes: determining whether there are any locations where the steel beam body may deform; and if so, controlling the movement of the support steel plate to the location where the steel beam body is deformed. Since deformation of the steel beam body can easily lead to the collapse of the erected bridge, controlling the movement of the support steel plate to the location where the steel beam body is deformed provides support at that location, preventing continuous deformation of the steel beam body, enhancing the structural strength of the steel beam body, and improving the safety of the erected bridge.

[0066] Optionally, when a deformation occurs in the steel beam, the supporting steel plate is moved to the location of the deformation while a warning message is issued. Since deformation of the steel beam could potentially lead to bridge collapse, issuing a warning message alerts vehicles and pedestrians to the safety hazard, prompting them to leave the bridge immediately, effectively ensuring their safety. Simultaneously, the warning can be sent to maintenance personnel, enabling timely bridge repairs and reducing the probability of serious accidents such as traffic accidents.

Optionally, the device may further include a communication interface 702 and a bus 703. The processor 700, communication interface 702, and memory 701 can communicate with each other via the bus 703. The communication interface 702 can be used for information transmission.
