Description

Technical Field

[0001] The utility model relates to the technical field of expansion joints, in particular to a novel expansion joint capable of self-diagnosis. Background Art

[0002] An expansion joint is a structure added to a building or bridge pavement. By designing appropriate space and shape, it can properly separate the various structures of the building or road, thereby achieving the functions of buffering, adjustment and load-bearing. Most of the existing expansion joints have poor self-diagnosis capabilities and generally require the use of external detection tools to detect the displacement inside the expansion joint.

[0003] For example, a Chinese utility model patent with announcement number CN213121745U discloses a bridge health intelligent diagnosis expansion joint. This scheme uses a third-party collection vehicle to collect the sound and frequency emitted when the load rolls over the expansion joint, and then judges the health status of the expansion joint and conducts real-time dynamic grasp, thereby reducing the workload of on-site inspections by inspection personnel and protecting them from traffic injuries. This active detection scheme cannot achieve self-diagnosis. Based on this, a new expansion joint that can self-diagnose is proposed. Utility Model Content

[0004] In order to solve the technical problems of expansion joint technology, the utility model provides a novel expansion joint capable of self-diagnosis.

[0005] The utility model is implemented by the following technical scheme: a new expansion joint capable of self-diagnosis, comprising two expansion joint bodies, one side of the two expansion joint bodies is respectively slidably connected with a grid-shaped covering plate, the lower sides of the two grid-shaped covering plates are abutted with a reference plate, both sides of the reference plates are respectively slidably connected with a movable plate, one side of the two expansion joint bodies is respectively provided with an expansion joint fixing mechanism for fixing the expansion joint body to a main body of a building project, one side of the two expansion joint bodies is respectively provided with a movable plate pushing mechanism for pushing the movable plate to one side, the lower side of the reference plate is provided with a reference plate fixing mechanism for fixing the reference plate, and one side of the two movable plates is provided with an offset measurement and control mechanism for obtaining the offset or expansion distance of the expansion joint body in real time.

[0006] As a further improvement of the above solution, the expansion joint fixing mechanism includes a plurality of No. 1 connecting piles respectively fixedly connected to one side of the two expansion joint bodies.

[0007] As a further improvement of the above-mentioned scheme, the movable plate pushing mechanism includes limit grooves opened on the two movable plates, and the inner sides of the two limit grooves are slidably connected with connecting plates fixedly connected to one side of the reference plate, and one end of the two connecting plates is provided with a movable plate resetting mechanism for resetting the movable plate.

[0008] As a further improvement of the above scheme, the movable plate resetting mechanism includes a fixed plate fixedly connected to one end of the two connecting plates, springs are respectively arranged between the two fixed plates and the movable plates, and a wedge-shaped pushing mechanism driven by the wedge principle is respectively arranged on one side of the two movable plates.

[0009] As a further improvement of the above scheme, the wedge-shaped pushing mechanism includes a No. 2 wedge plate fixedly connected to one side of the two movable plates, and one side of the two No. 2 wedge plates is respectively provided with a No. 1 wedge plate fixedly connected to one side of the two expansion joint bodies.

[0010] As a further improvement of the above solution, the reference plate fixing mechanism includes a scale plate fixedly connected to the lower side of the reference plate, and a plurality of No. 2 fixing piles are fixedly connected to the lower side of the scale plate.

[0011] As a further improvement of the above solution, the offset measurement and control mechanism includes laser rangefinders respectively arranged on one side of the two movable plates.

[0012] Through the above technical solution, the laser rangefinder can actively scan and detect the physical and chemical conditions of the surrounding expansion joints.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model cooperates with each other through the expansion joint body, the first wedge plate, the second wedge plate, the movable plate, the reference plate and the spring. When the expansion joint bodies are close to each other due to external factors such as temperature or earthquake, the first wedge plate pushes the second wedge plate and the movable plate to deviate to one side. There is no need to use third-party detection means to inspect the expansion joint. At this time, the laser rangefinder can record the displacement data in real time and send the data in the form of a signal, so as to convert the deformation and displacement between the expansion joint bodies.

[0015] 2. The utility model cooperates with each other through the expansion joint main body and the grid-shaped covering plate. The contact between the expansion joint main body and the grid-shaped covering plate adopts a sliding connection. When the expansion joint main body changes due to external factors, regardless of longitudinal or lateral force, the gap between the two expansion joint main bodies can be effectively covered, which can improve the driving experience of road drivers.

[0024] Please combine Figure 1 or Figure 2 As shown, the expansion joint fixing mechanism includes a plurality of No. 1 connecting piles 1 respectively fixedly connected to one side of the two expansion joint bodies 2. The No. 1 connecting piles 1 are made of steel wire rope, steel bar or steel plate material, and the material and the number set on one side can be determined according to the specific construction scene.

[0025] Please combine Figure 3 As shown, the movable plate pushing mechanism includes limit grooves 14 opened on the two movable plates 4, and the inner sides of the two limit grooves 14 are slidably connected with connecting plates 13 fixedly connected to one side of the reference plate 10, and one end of the two connecting plates 13 is provided with a movable plate resetting mechanism for resetting the movable plate 4.

[0026] Please combine Figure 3 As shown, the movable plate resetting mechanism includes a fixed plate 12 fixedly connected to one end of the two connecting plates 13, and springs 11 are respectively arranged between the two fixed plates 12 and the movable plate 4. The spring 11 is an elastic component, and other elastic components with better toughness and service life can also be selected, such as composite rubber. A wedge-shaped pushing mechanism driven by the wedge principle is respectively arranged on one side of the two movable plates 4.

[0030] The implementation principle of a new type of expansion joint capable of self-diagnosis in the embodiment of the present application is as follows: first, the No. 1 connecting pile 1 is solidified together with the concrete to fix the two expansion joint bodies 2, and then the reference plate 10 is fixed at a position that is not easily disturbed by external environmental factors through the No. 2 fixing pile 5 as a reference system; when the external environment changes, causing the expansion joint body 2 to move forward, the No. 1 wedge plate 7 pushes the No. 2 wedge plate 8, and the No. 2 wedge plate 8 directly drives the movable plate 4 to deflect to one side, and the spring 11 is deformed.
