Abstract
Description
Technical Field
[0001] The invention relates to the technical field of deformation monitoring devices, and more specifically to a damper limiting and monitoring dual-function device. Background Art
[0002] Energy dissipation and shock absorption technology consumes the energy of earthquake or wind vibration through the hysteresis or viscous energy dissipation of additional dampers, thereby achieving the purpose of protecting the main structure. Research has shown that this technology can effectively improve the structural response under earthquake or wind vibration, and has therefore been widely promoted and applied in my country in recent years.
[0003] Dampers are widely used, but the actual data on the output or deformation of dampers during earthquakes or typhoons is relatively scarce, which brings certain difficulties to the vibration and post-seismic evaluation of the project. In addition, dampers mainly work within the surface. If out-of-plane deformation occurs, the damper is prone to damage and failure.
[0004] There are many monitoring methods at present. The most commonly used solution is to add sensors to the structure, then collect relevant data through data acquisition instruments, and finally sort out the data to get some reference values. This solution is costly, has poor durability, and requires external energy. Earthquakes and wind vibrations are relatively random, and the above monitoring methods may have the problem of difficulty in collecting data. In view of this, we propose a dual-function device for damper limit and monitoring. Summary of the invention
[0005] The purpose of the present invention is to provide a dual-function device for damper limiting and monitoring, so as to solve the technical problems that the current existing monitoring means are high in cost, poor in durability, require external energy, are highly random in earthquake and wind vibration, and are difficult to collect data.
[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a dual-function device for limiting and monitoring a damper, comprising a bottom plate with a core plate arranged in the center of the top;
[0007] Side plates are centrally arranged at the edge positions of both sides of the upper end surface of the bottom plate, and polytetrafluoroethylene plates are symmetrically and movably installed on one side of the side plate facing the core plate, and two long oval holes are symmetrically formed inside the polytetrafluoroethylene plate, and one long oval hole is formed inside the side plate at a position corresponding to the second long oval hole, and bolts are commonly arranged inside the first and second long oval holes, and studs are symmetrically arranged at the center on both sides of the core plate, and the studs are arranged between the polytetrafluoroethylene plates on the same side.
[0008] The present invention effectively limits the out-of-plane deformation of the damper through extrusion between the side panels, the polytetrafluoroethylene panels and the core panels, thereby achieving the purpose of better protecting the damper. At the same time, the polytetrafluoroethylene panels are squeezed by the bolts arranged on the core panels, so that the polytetrafluoroethylene panels move within the plane. The movement trajectory can approximately represent the deformation of the damper, thereby achieving the purpose of damper deformation monitoring. The present invention has a simple structure and is reusable. It does not require external energy and can ensure the true and effective recording of the damper deformation after an earthquake or wind vibration, providing strong support for project evaluation after an earthquake or vibration.
[0009] Preferably, one end of the bolt is welded to the core plate, and the other end of the bolt abuts against the side plate.
[0010] Preferably, a surface of the polytetrafluoroethylene plate away from the core plate is movably attached to the side plate, and a gap is formed between the surface of the polytetrafluoroethylene plate away from the side plate and the core plate.
[0011] Preferably, the bolt is arranged in the gap, and the width of the gap formed between the polytetrafluoroethylene plate and the core plate is mm.

[0021] like Figure 1-Figure 3 As shown, the present invention relates to a dual-function device for limiting and monitoring a damper, comprising a bottom plate 1 with a core plate 4 centrally arranged on the top, side plates 2 centrally arranged on both sides of the upper end surface of the bottom plate 1, polytetrafluoroethylene plates 6 symmetrically and movably installed on one side of the side plate 2 facing the core plate 4, long oval holes 7 symmetrically formed inside the polytetrafluoroethylene plates 6, long oval holes 1 3 formed inside the side plate 2 at positions corresponding to the long oval holes 2 7, bolts 8 are commonly arranged inside the long oval holes 1 3 and the long oval holes 2 7, studs 9 are symmetrically arranged on both sides of the core plate 4, and the studs 9 are arranged between the polytetrafluoroethylene plates 6 located on the same side.
[0022] In an embodiment of the present invention, one end of the bolt 9 is welded to the core plate 4, and the other end of the bolt 9 abuts against the side plate 2. The side of the polytetrafluoroethylene plate 6 away from the core plate 4 is movably fitted to the side plate 2, and a gap is formed between the side of the polytetrafluoroethylene plate 6 away from the side plate 2 and the core plate 4. The bolt 9 is arranged in the gap, and the width of the gap formed between the polytetrafluoroethylene plate 6 and the core plate 4 is 10 mm.
[0023] In an embodiment of the present invention, the bottom end of the side panel 2 is detachably connected to the upper end surface of the bottom panel 1, the bottom end of the polytetrafluoroethylene panel 6 is detachably connected to the upper end surface of the bottom panel 1, the bottom end of the core panel 4 is detachably connected to the upper end surface of the bottom panel 1, a top panel 5 is provided at the top end of the core panel 4, and the core panel 4 and the top panel 5 are connected in an integral structure.
[0024] The side panels 2 and the bottom panel 1 are connected by plug-fitting, the core panel 4 and the bottom panel 1 are connected by plug-fitting, and the side panels 2 and the bottom panel 1 as well as the core panel 4 and the bottom panel 1 can be fixed by screws after being plug-fitted.
[0025] Working principle: This embodiment provides a dual-function device for damper limiting and monitoring. When in use, when the structure is deformed, the core plate 4 is squeezed by the polytetrafluoroethylene plates 6 on both sides, thereby playing the role of out-of-plane limiting, ensuring that the damper only moves within the plane. At the same time, when the structure moves, relative deformation will occur between the core plate 4 and the side plate 2. During this process, the bolts 9 on the core plate 4 will push the movement of the polytetrafluoroethylene plate 6, and its movement trajectory is the deformation trajectory of the damper, thereby achieving the purpose of damper deformation monitoring.
