Description

Technical Field

[0001] The invention relates to the technical field of building structures, in particular to a stress self-balancing reinforcement device for a steel structure. Background Art

[0002] At present, steel structures are widely used in various building structures for reinforcement and support. However, during the use of steel structures, due to overload, fatigue, environmental factors, etc., the actual structural stress may exceed the design range. Long-term high stress state will accelerate the fatigue damage and corrosion process of steel structures, leading to structural deformation or even destruction. The existing technology lacks a device that can monitor stress in real time and automatically adjust the balance, and does not effectively prevent stress concentration and structural damage of steel structures. Summary of the invention

[0003] The purpose of the present invention is to provide a self-balancing steel structure stress reinforcement device, which can keep the stress state of the steel structure within a reasonable range, thereby extending the service life of the steel structure and facilitating installation and layout.

[0004] To achieve the above-mentioned purpose, the present invention provides a self-balancing stress reinforcement device for a steel structure, comprising a lower hydraulic plate, on which a motor is installed, the motor is connected to a hydraulic spring device installed on the lower hydraulic plate through a hydraulic medium pipe, and the top of the hydraulic spring device is connected to an upper hydraulic plate; a control system is installed on one side of the lower hydraulic plate, the motor is connected to the control system through a wire, and the control system is connected to a stress sensing sheet through a wire.

[0005] Preferably, the hydraulic spring device includes a hydraulic support column fixed on the lower hydraulic plate, a fixed plate is arranged above the hydraulic support column, and a fixed rod fixed to the lower hydraulic plate is connected below the fixed plate; the interior of the hydraulic support column is a cavity structure and is provided with a slider, a spring is fixed above the slider, an opening corresponding to the spring is opened in the middle of the fixed plate, and a threaded joint is connected to the top of the spring.

[0006] Preferably, a threaded sleeve corresponding to the threaded joint is provided at the bottom of the upper hydraulic plate.

[0007] Preferably, the side surface of the threaded sleeve is connected to a reinforcing plate fixed to the bottom of the upper hydraulic plate.

[0008] Preferably, the size of the lower hydraulic plate is smaller than that of the upper hydraulic plate.

[0009] Preferably, the control system includes a protective shell, a fixing groove is provided at the bottom of the side of the protective shell, and a central control circuit board, a Bluetooth transceiver module and a battery pack are provided inside the protective shell.

[0010] Preferably, a main control circuit, a drive circuit and a sensor circuit are arranged on the central control circuit board.

[0011] Preferably, four and eight threaded holes are respectively provided on the upper hydraulic plate and the lower hydraulic plate.

[0012] Preferably, the lower hydraulic plate is a hollow structure and is connected to the hydraulic spring device and the hydraulic medium pipe.

[0013] Preferably, at least two stress sensing sheets are provided.

[0014] Therefore, the beneficial effects of the above-mentioned steel structure stress self-balancing reinforcement device adopted by the present invention are as follows:

[0015] (1) Improve structural safety: The present invention can monitor stress in real time and automatically adjust the balance, effectively preventing stress concentration and structural damage. For example, when an earthquake occurs, the steel structure building is affected by the seismic force, and the stress of beams, columns and other components increases sharply. The device can balance the stress in time, reduce the risk of structural damage, and ensure the safety of personnel and property.

[0016] (2) Extending the service life of the structure: Through stress self-balancing, the stress state of the steel structure can always be kept within a reasonable range, reducing the generation and expansion of fatigue cracks, slowing down the corrosion rate, and thus extending the service life of the structure. For example, for bridge steel structures that bear dynamic loads for a long time, after using this device, the maintenance cycle of the bridge can be extended, reducing the cost of the entire life cycle.

[0017] (3) Simple and convenient construction: The stress sensing sheet can be fixed on the surface of the steel structure by gluing or welding. The stress adjustment part can be reasonably arranged according to the layout of the steel structure, and then connected to the control system through simple pipes and lines. In the new steel structure project or the reinforcement project of the existing structure, the installation of the device can be completed without complex construction technology and large-scale construction equipment.

The top of the hydraulic spring device 4 is connected to an upper hydraulic plate 5. Four threaded holes 8 are provided on the upper hydraulic plate 5, and eight threaded holes 8 are provided on the lower hydraulic plate 1, so that the upper hydraulic plate 5 and the lower hydraulic plate 1 are respectively fixedly connected to the main beam and the secondary beam by bolts.

[0029] A control system 7 is installed on one side of the lower hydraulic plate 1, the motor 2 is connected to the control system 7 through a wire, and the control system 7 is connected to a stress sensing sheet 6 through a wire. In this embodiment, two stress sensing sheets 6 are provided, which are respectively welded on both sides of the main beam to detect in real time whether stress changes occur.

[0030] Among them, Figure 2 As shown, the hydraulic spring device 4 includes a hydraulic support column 41 fixed on the lower hydraulic plate 1. In this embodiment, the lower hydraulic plate 1 is a hollow structure and is connected to the hydraulic spring device 4 and the hydraulic medium pipe 3. A fixing plate 42 is arranged above the hydraulic support column 41, and a fixing rod 43 fixed to the lower hydraulic plate 1 is connected below the fixing plate 42 to fix the hydraulic support column 41.

A spring 44 is fixed above the slider, and an opening corresponding to the spring 44 is opened in the middle of the fixing plate 42, and a threaded joint 45 is connected to the top of the spring 44.

[0031] like Figure 3 As shown, a threaded sleeve 51 corresponding to the threaded joint 45 is provided at the bottom of the upper hydraulic plate 5, so as to facilitate the connection of the upper hydraulic plate 5 to the hydraulic spring device 4.
