Description

Technical Field

[0001] The invention relates to the technical field of building engineering structures, and in particular to an external load adaptive component based on the coordinated work of multiple intelligent struts and a working method thereof. Background Art

[0002] Under the action of external loads, beams, columns and other components are prone to buckling, causing structural collapse, resulting in serious casualties and property losses. In addition, as engineering needs continue to evolve, it is sometimes necessary to adjust the state of components according to external conditions or load changes (such as fire, dynamic loads, earthquakes, temperature, etc.) to ensure the stability and safety of the structure.

[0003] The traditional method increases the bearing capacity of the structure by increasing the cross-sectional size of the components and improving the strength of the materials. On the one hand, it increases the deadweight of the structure and reduces the clearance area, which is not economical. On the other hand, it cannot be adjusted in real time according to the external load conditions, and it is difficult to adapt to changes in the external environment or fluctuations in the structural load, and it cannot actively and flexibly improve the stability and safety of the components. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide an external load adaptive component based on the collaborative work of multiple intelligent struts and its working method. By setting an intelligent telescopic device, the adaptive function of the component under the action of external load can be realized, effectively improving the stability and safety of the structure.

[0005] The object of the present invention can be achieved by the following technical solutions: an external load adaptive component based on the coordinated work of multiple intelligent struts, comprising a component, a prestressed component is connected between the two ends of the component, an intelligent telescopic device is arranged on the outer wall of the component, the intelligent telescopic device is connected to the prestressed component, the intelligent telescopic device comprises a displacement sensor, a controller and a strut assembly, the displacement sensor is used to collect the lateral displacement of the component and transmit it to the controller;

[0006] The controller is used to control the expansion and contraction of the strut assembly along its own axis in real time until the maximum lateral displacement position of the component is reached;

[0007] The prestressed component is used to push the component toward the initial position so that the lateral displacement of the component is within a preset safety threshold.

[0008] Furthermore, after the extension and retraction action, the support rod assembly forms a state without supporting points, a single-point supported triangle state or a two-point supported trapezoidal state.

[0009] Furthermore, the strut assembly includes a first strut and a second strut, one end of the first strut is connected to the controller via a rotating block, one end of the second strut is connected to the displacement sensor via a rotating block, the other end of the first strut and the other end of the second strut are connected via a rotating block, and the rotating block moves and rotates freely along the elongation of the strut.

[0010] Furthermore, the surface of the rotating block between the first support rod and the second support rod is smooth, and is used to provide support to the prestressed component and apply prestress thereto.

[0011] Furthermore, the controller and the displacement sensor are respectively fixedly arranged on the outer wall of the component.

[0012] Furthermore, when the component is in a bending state, an intelligent telescopic device is arranged on one side of the component.

[0013] Furthermore, when the member is in a compressive buckling state, if there is a weak axis, the intelligent telescopic device is symmetrically arranged along the weak axis;

[0014] If there is no weak axis, the intelligent telescopic devices are arranged symmetrically around the component.

[0015] Furthermore, the prestressed component is fixedly connected to both ends of the component by anchors.

[0016] Furthermore, the cross-section of the component is a circular, square or I-shaped symmetrical shape.

[0017] A working method of an external load adaptive component based on the collaborative work of multiple intelligent struts comprises the following steps:

[0019] S2, the controller determines whether the current component has reached the maximum lateral deformation, if so, executes step S3, otherwise returns to step S1;

[0020] S3. The controller outputs instructions to control the strut assembly to perform telescopic action to reach the maximum lateral displacement position of the component, so that the prestressed component is tensioned and a prestress difference is generated on the left and right sides of the component, forming a force opposite to the lateral deformation, thereby pushing the component toward the initial position, so that the lateral displacement of the component is within the preset safety threshold.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] The present invention is designed to connect a prestressed component between the two ends of the component, and to set an intelligent telescopic device on the outer wall of the component, wherein the intelligent telescopic device is connected to the prestressed component, wherein the intelligent telescopic device includes a displacement sensor, a controller and a strut assembly, and uses the displacement sensor to collect the lateral displacement of the component and transmit it to the controller; uses the controller to control the strut assembly to telescope along its own axis in real time until the maximum lateral displacement position of the component is reached and the prestressed component is tensioned; uses the tensioned prestressed component to push the component toward the initial position, so that the lateral displacement of the component is within the preset safety threshold. In this way, the position of the strut assembly and the stress of the prestressed component can be adjusted in real time according to the external load, thereby adapting to changes in the external environment or fluctuations in the structural load, and effectively improving the stability and safety of the structure.

[0023] The support rod assembly designed in the present invention includes a first support rod and a second support rod, one end of the first support rod is connected to the controller through a rotating block, one end of the second support rod is connected to the displacement sensor through the rotating block, and the other end of the first support rod and the other end of the second support rod are connected through a rotating block, wherein the rotating block can move and rotate freely with the elongation of the support rod, and the surface of the rotating block between the first support rod and the second support rod is smooth and is used to provide support to the prestressed component and apply prestress thereto, so that the support rod assembly can flexibly and reliably adjust the position of its support point to form a state without support points and support shapes such as a single-point support triangle and a two-point support trapezoid, and the support points can cover the entire length range of the component and can ensure the stress application to the prestressed component.

[0024] The present invention takes into account the bending state and compressive buckling state of the component, and designs the intelligent telescopic device to be arranged symmetrically around the component and up and down. In addition, different numbers of intelligent telescopic devices can be arranged according to actual load conditions and boundary conditions, effectively improving the performance of the component to adapt to various working conditions.

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 1 and Figure 2 As shown, an external load adaptive component based on the collaborative work of multiple intelligent struts includes a component 1 (which can be a concrete or steel component, and its cross-section can be a symmetrical shape such as a circle, square, or I-shape), a prestressed component 3 (which can be made of fiber-reinforced composite materials, steel, or other materials with appropriate strength and stiffness) is connected between the two ends of the component 1, and an intelligent telescopic device is arranged on the outer wall of the component 1, and the intelligent telescopic device is connected to the prestressed component 3, and the intelligent telescopic device includes a displacement sensor 7, a controller 8, and a strut assembly.

[0032] The displacement sensor 7 is used to collect the lateral displacement of the component 1 and transmit it to the controller 8;

[0033] The controller 8 is used to control the extension and retraction of the strut assembly along its own axis in real time until the maximum lateral displacement position of the component 1 is reached;

[0034] The prestressed component 3 is used to push the component 1 toward the initial position so that the lateral displacement of the component 1 is within a preset safety threshold.

[0035] After the support rod assembly is controlled, the position of the support point can be freely adjusted to form a state without support points and support shapes such as a single-point support triangle and a two-point support trapezoid. The support points can cover the entire length range of the component 1.

[0036] The strut assembly includes a first strut 4 and a second strut 5. One end of the first strut 4 is connected to the controller 8 through a rotating block 6, and one end of the second strut 5 is connected to the displacement sensor 7 through the rotating block 6. The controller 8 and the displacement sensor 7 are respectively fixed on the outer wall of the component 1. The other end of the first strut 4 and the other end of the second strut 5 are connected through the rotating block 6. The rotating block 6 rotates freely in a single direction as the struts are elongated. The surface of the rotating block 6 between the first strut 4 and the second strut 5 is smooth and is used to provide support to the prestressed component 3.

[0037] In practical applications, different numbers of intelligent expansion and contraction devices may be arranged on the component 1 according to actual load conditions and boundary conditions. For example, when the component 1 is in a bending state, the intelligent expansion and contraction device may be arranged on one side of the component 1.

[0038] Considering that the member 1 is in a compressive buckling state, if a weak axis exists, the intelligent expansion and contraction devices are arranged symmetrically along the weak axis; if no weak axis exists, the intelligent expansion and contraction devices are arranged symmetrically around the member.

[0039] In addition, the prestressed component 3 can be tensioned and fixedly connected to both ends of the component 1 through the anchor 2. The anchor 2 has excellent anchoring efficiency and can ensure stable connection with the component 1 through welding or bolting.

[0040] The working method of the external load adaptive component based on the collaborative work of multiple intelligent struts includes:

[0041] S1, the displacement sensor 7 collects the lateral displacement of the component 1 in real time and transmits it to the controller 8;

[0042] S2, the controller 8 determines whether the current component 1 has reached the maximum lateral deformation, if it is determined to be yes, then executes step S3, otherwise returns to step S1;

[0043] S3, the controller 8 outputs instructions to control the strut assembly to perform telescopic action to reach the maximum lateral displacement position of the component 1, so that the prestressed component 3 is tensioned and a prestress difference is generated on the left and right sides of the component 1, forming a force opposite to the lateral deformation, thereby pushing the component 1 toward the initial position, so that the lateral displacement of the component 1 is within the preset safety threshold.

[0044] In this embodiment, the anchor 2 is symmetrically fixed on the upper and lower parts and both sides of the component 1; the displacement sensor 7 is symmetrically fixed on both sides of the mid-span of the component 1; the displacement sensor 7 is connected to the rotating block 6, the second support rod 5, the rotating block 6, the first support rod 4, the rotating block 6, and the controller 8 in sequence, and the controller 8 is fixed on the component 1; then the intelligent telescopic device is further symmetrically arranged on the upper and lower parts and the left and right sides; finally, the prestressed component 3 is tensioned and fixed by the anchor 2 to form an external load adaptive component containing an intelligent telescopic device.

[0045] The lateral displacement along the component 1 is obtained by the displacement sensor 7, and the data signal is transmitted to the controller 8 in real time; the controller 8 automatically analyzes whether the maximum lateral deformation of the component 1 under the external load reaches the safety threshold. If the safety threshold is not reached, the controller 8 remains silent. When the safety threshold is exceeded, the controller 8 sends a command to the first support rod 4 and the second support rod 5 to control the extension and contraction of the support rods (the process changes as shown in FIG. Figure 3 to Figure 5 As shown in the figure, the rotating block 6 is adjusted to the same level as the maximum deformation of the component 1. At this time, due to the displacement of the rotating block 6, the prestressed component 3 is stretched, and a prestress difference is formed on the left and right sides, forming a force opposite to the deformation, pushing the component 1 towards the initial position (as shown in the figure). Figure 6 As shown), and adjust the length and position of the strut in real time until the lateral displacement of component 1 is within the safety threshold.

[0046] In summary, this solution uses the information fed back by the sensor to automatically adjust the length and position of the brace member and tension the prestressed component. Through the stress difference of the prestressed component, a function similar to a "spring" is achieved, thereby ensuring the safety of the component.

[0047] The initial state of this solution occupies a small space, and can adjust the telescopic action of the brace and the stress of the prestressed components in real time according to the external load conditions to adapt to changes in the external environment or fluctuations in the structural load, thereby improving the stability and safety of the structure. This technology has a wide range of applications, covering many fields such as construction engineering, bridge engineering, and earthquake engineering. This adaptive technology brings greater flexibility and safety to structural design.

[0048] In this solution, the design of intelligent telescopic devices gives the brace components flexibility and adaptability, allowing them to automatically adjust their length and position according to the external environment, load changes or other factors. This feature enables the brace components to better adapt to different working conditions and improves the flexibility of the overall structure. The controller can adjust the length of the brace based on real-time data and feedback information to ensure the stability and safety of the structure under different load conditions. The intelligent telescopic device can be adjusted as needed to reduce energy consumption when support is not required. This intelligent adjustment capability can help save energy costs and reduce operating costs. This external load adaptive component combined with intelligent technology represents a technological innovation in the engineering field, bringing new development directions and application prospects to fields such as construction engineering, and helping to promote the engineering field to develop in a more efficient and intelligent direction.
