[0002] A coupling beam is a beam used to connect wall members in a shear wall structure and is connected within the plane of the wall member. The coupling beam generally has a small span and a large cross-section, and the wall connected to the coupling beam has a large stiffness. Under the action of wind loads and earthquakes, the internal force of the coupling beam is often very large, so the coupling beam is easily damaged when extreme natural disasters such as earthquakes occur.

[0003] For the reinforcement and repair of the damaged connecting beam, the fiber composite material and steel plate are usually pasted. For example, the fiber cloth is used to reinforce the connecting beam, and the U-shaped hoop + steel plate strip + through-wall screw can be used. The U-shaped hoop is pasted in the direction perpendicular to the axis of the connecting beam. However, when extreme natural disasters such as earthquakes occur again, the connecting beam often needs to be reinforced and repaired again. For earthquake-prone areas, the construction difficulty and construction volume of workers have caused considerable trouble. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1-4 As shown, a reinforcement structure for partially removing a damaged coupling beam provided by an embodiment of the present invention includes two mounting plates 1 respectively connected to the residual ends of the coupling beam, and also includes:

[0026] A support mechanism 2, the support mechanism 2 comprising a support rod 21 and a support sleeve 22, the support rod 21 being mounted on the mounting plate 1, and one end of the support rod 21 away from the mounting plate 1 being slidably mounted in the support sleeve 22, a piston plate 23 being slidably mounted in the support sleeve 22, and the piston plate 23 being connected to the support rod 21, a damping plate 24 being further mounted in the support sleeve 22, a guide rod 25 being annularly mounted on the side wall of the damping plate 24, and a spiral groove 26 matching the guide rod 25 being provided inside the side wall of the support sleeve 22, a connecting plate 27 being mounted on the end of the support sleeve 22 away from the support rod 21, and the two connecting plates 27 at both ends being connected to each other via a connecting assembly 5 with adjustable damping; and

[0027] The adjusting mechanism 3 comprises a telescopic connecting rod 31 connected to the damping plate 24, and an installation cavity 32 opened in the connecting plate 27, the end of the telescopic connecting rod 31 away from the damping plate 24 is inserted into the installation cavity 32, and a winding wheel 33 is installed on the end of the telescopic connecting rod 31 located in the installation cavity 32, and a connecting rope 34 is wound on the winding wheel 33, and a pressure plate 35 is also slidably installed in the installation cavity 32, and one end of the connecting rope 34 is connected to the pressure plate 35, and the side of the pressure plate 35 away from the connecting rope 34 is connected to the side wall of the installation cavity 32 through a first spring 36, and a control component 4 for adjusting the damping of the connecting component 5 is also provided in the installation cavity 32, and the control component 4 is provided in two groups, and the two groups of the control components 4 are symmetrically arranged on both sides of the pressure plate 35.

[0028] In the embodiment of the present invention, when in use, the two mounting plates 1 are respectively fixed to the residual ends of the connecting beams at both ends, and then the two connecting plates 27 are connected to each other using the connecting assembly 5, so that the installation of the device can be completed. When vibration occurs, the support rod 21 will drive the piston plate 23 to slide in the support sleeve 22, and the piston plate 23 will correspondingly drive the damping plate 24 to move in the support sleeve 22. During this process, under the cooperation of the guide rod 25 and the spiral slide groove 26, the damping plate 24 will perform a combined sliding and rotating movement. Compared with simple linear sliding, this movement mode can provide greater damping, thereby improving the shock absorption effect. During the movement process, the damping plate 24 can synchronously drive the telescopic connecting rod 31 to rotate, and the telescopic connecting rod 31 drives the winding wheel 33 to rotate synchronously. The winding wheel 33 can reel / unwind the connecting rope 34, thereby driving the pressing plate 35 to move. The pressing plate 35 can squeeze the control assembly 4, and the control assembly 4 adjusts the damping of the connecting assembly 5 according to the pressure feedback from the pressing plate 35, thereby offsetting the energy generated by the vibration.

[0029] like Figure 1 and 5 As shown, as a preferred embodiment of the present invention, the connecting component 5 includes a plurality of connecting columns 51 installed on the connecting plate 27, and each connecting column 51 on the two connecting plates 27 is grouped in pairs, and the two connecting columns 51 in the same group are interconnected by an arc-shaped elastic plate 52, and arc-shaped elastic plates 52 are provided at both ends of the connecting column 51, and two symmetrically arranged dampers 53 are connected between the two connecting columns 51, and the two ends of the damper 53 are respectively slidably installed on one connecting column 51, and the connecting column 51 is also provided with an electric telescopic rod 55 for driving the two dampers 53 between the same group of connecting columns 51 to move according to the signal feedback of the control component 4.

[0030] In the embodiment of the present invention, when in use, the electric telescopic rod 55 can flexibly adjust the support position of the damper 53 according to the signal fed back by the control component 4. Under the squeezing action of the connecting plates 27 on both sides, the arc-shaped elastic plates 52 at both ends of the connecting column 51 will bend, thereby absorbing the energy generated by the vibration. The control component 4 changes the energy consumed to produce the distance change between the two connecting columns 51 (that is, the energy required to change the arc-shaped elastic plate 52 to undergo the same elastic deformation) by adjusting the spacing between the two dampers 53 and the support position of the damper 53 relative to the connecting column 51, thereby adjusting the motion damping between the two connecting columns 51 to meet different usage requirements. The position of the damper 53 is adjusted so that the damper 53 does not need to be in a high-damping working state all the time, but is in a high-damping state only when it is vibrated, thereby extending the service life of the component.

[0031] like Figure 4 As shown, as a preferred embodiment of the present invention, the control component 4 includes a mounting block 41 and a push block 42, the push block 42 is connected to a push rod 43, and the push rod 43 is slidably installed in the mounting block 41, and the push rod 43 is connected to the inside of the mounting block 41 through a second spring 44, and a pressure sensor 45 is installed inside the mounting block 41.

[0032] In the embodiment of the present invention, when in use, under the cooperation of the connecting rope 34 and the first spring 36, the pressure plate 35 can squeeze one group of the control components 4 on both sides thereof. After being squeezed by the pressure plate 35, the push block 42 can drive the push rod 43 to squeeze the pressure sensor 45. The pressure sensor 45 controls the extension and retraction of the electric telescopic rod 55 according to the pressure of the push rod 43, thereby realizing the position adjustment of the damper 53 and achieving the effect of adjusting the damping.

[0033] As a preferred embodiment of the present invention (not shown in the drawings), the two connecting plates 27 are connected to each other by four groups of connecting columns 51, and the four groups of connecting columns 51 are respectively distributed on the four sides of the connecting plate 27. The four connecting columns 51 on the same connecting plate 27 are distributed in a rectangular shape, which can ensure the stability of the connection and provide effective damping adjustment.

[0034] like Figure 6 As shown, as a preferred embodiment of the present invention, detachable hexagon socket bolts 56 are installed at both ends of the damper 53, a rotating bearing 57 is rotatably installed on the hexagon socket bolts 56, and a sliding groove matching the rotating bearing 57 is provided on the connecting column 51.

[0035] In the embodiment of the present invention, when in use, the hexagon socket bolt 56 is connected to the damping rod 54 at the end of the damper 53, thereby fixing the damper 53 between the two connecting columns 51. Under the cooperation of the rotating bearing 57, the damper 53 can slide flexibly between the connecting columns 51, thereby ensuring the adjustment effect, reducing the wear of the hexagon socket bolt 56, and extending the service life of the device.

[0036] like Figure 1 and 7 As shown, as a preferred embodiment of the present invention, the support sleeve 22 and the mounting plate 1 are further connected via an auxiliary support assembly 6 .

[0037] In the embodiment of the present invention, the auxiliary support assembly 6 includes a mounting ring 61 mounted on the side wall of the support sleeve 22, and a plurality of connecting rods 62 are mounted in a ring array on the mounting ring 61. The end of the connecting rod 62 away from the mounting ring 61 is rotatably connected to a slider 63, and the slider 63 is slidably mounted in a sliding groove 64 provided on the mounting plate 1, and a third spring 65 is also connected between the slider 63 and the side wall of the sliding groove 64. When in use, the support sleeve 22 can drive the mounting ring 61 to move synchronously, and the mounting ring 61 drives the slider 63 to slide in the sliding groove 64 through the connecting rod 62. During the movement, the sliding groove 64 will squeeze or stretch the third spring 65, thereby providing an auxiliary damping effect and improving the shock absorption effect of the device.

[0038] Working principle: When in use, fix the two mounting plates 1 to the residual ends of the connecting beam at both ends respectively, and then use the connecting assembly 5 to connect the two connecting plates 27 to each other, and the installation of the device can be completed. When vibration occurs, the support rod 21 will drive the piston plate 23 to slide in the support sleeve 22, and the piston plate 23 will correspondingly drive the damping plate 24 to move in the support sleeve 22. During this process, under the cooperation of the guide rod 25 and the spiral slide groove 26, the damping plate 24 will perform a combination of sliding and rotating movement. Compared with simple linear sliding, this movement mode can provide greater damping, thereby improving the shock absorption effect. During the movement process, the damping plate 24 can synchronously drive the telescopic connecting rod 31 to rotate, and the telescopic connecting rod 31 drives the winding wheel 33 to rotate synchronously. The winding wheel 33 can reel in / unreel the connecting rope 34, thereby driving the pressure plate 35 to move. The pressure plate 35 can squeeze the control component 4. After being squeezed by the pressure plate 35, the push block 42 can drive the push rod 43 to squeeze the pressure sensor 45. The pressure sensor 45 controls the extension and retraction of the electric telescopic rod 55 according to the pressure of the push rod 43, thereby realizing the position adjustment of the damper 53, thereby changing the energy required for the arc-shaped elastic plate 52 to undergo the same elastic deformation, and realizing the adjustment of the motion damping between the two connecting columns 51, thereby offsetting the energy generated by the vibration and adapting to different usage requirements.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
