Description

Technical Field

[0001] The invention relates to the technical field of building reinforcement, and in particular to a building reinforcement device with earthquake-resistant function. Background Art

[0002] The main function of building reinforcement devices is to improve the structural safety and durability of buildings and ensure that they remain stable under various external forces. These devices effectively respond to the risk of damage caused by earthquakes, wind loads, settlements or human factors by enhancing the bearing capacity of building components. Common reinforcement methods include adding steel structure support, pasting carbon fiber cloth, adding shear walls or using prestressed technology. Reinforcement devices can improve the overall stiffness of buildings, reduce cracks and deformations, and extend the service life of buildings. In addition, in the renovation of old buildings, reinforcement devices can enable them to meet modern safety standards, avoid demolition and reconstruction, and save resources. Through scientific design and construction, reinforcement devices not only improve the seismic performance of buildings, but also enhance their wind resistance, explosion resistance and other capabilities, providing people with a safer living and working environment.

[0003] Traditional building reinforcement devices are widely used in the engineering field, but due to the limitations of their structure and working principle, there are often some problems that cannot be ignored. For example, the structural design of traditional building reinforcement devices is usually targeted at specific building components, such as columns, walls or beams, and it is difficult to apply to all components at the same time. For example, the reinforcement device used for columns may not be able to effectively fix the wall or beam, resulting in poor reinforcement effect. In addition, the height adjustment capacity of these devices is limited and cannot flexibly adapt to building structures of different heights. Traditional devices usually use fixed lengths or simple mechanical adjustments, which are difficult to accurately match the actual height of the building, increasing the difficulty and cost of construction. Another defect is that traditional reinforcement devices cannot adjust the prestress applied to the building. Prestress is a crucial factor in the reinforcement process and directly affects the stability and durability of the structure. Traditional devices usually rely on fixing bolts or welding methods, and cannot dynamically adjust the prestress according to the actual needs of the building, resulting in unsatisfactory reinforcement effects and may even cause additional damage to the building.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Through the support mechanism, the building reinforcement device can adapt to building components with different shapes such as columns and walls to achieve reinforcement effects. The design of the support mechanism takes into account the geometric characteristics of different components, so that it can fit closely to the shapes of different building components.

The design of the adjustment unit enables it to adjust the prestress according to the actual needs of the building to ensure that the reinforcement effect matches the stress state of the building structure. By controlling the size of the prestress, the device can improve the stability and seismic resistance of the building. When an earthquake occurs, the deformation of the building will release energy. The adjustment unit absorbs and consumes this energy to reduce the impact on the building structure. This function enables the device to not only provide static reinforcement, but also play a protective role under dynamic conditions, thereby enhancing the overall seismic resistance of the building. The flexibility of the adjustment unit enables it to adapt to earthquakes of different intensities and ensure the safety of the building under different working conditions.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] Example 1, reference Figure 1-Figure 12 , which is the first embodiment of the present invention, provides a building reinforcement device with earthquake resistance function, including a column 1, and also includes two support mechanisms 2 symmetrically installed on both sides of the column 1, and two fixing mechanisms 3 symmetrically installed on the top and bottom of the support mechanism 2; the support mechanism 2 includes a plurality of hoop units assembled on the outside of the column 1 in a linear array, and a lifting unit assembled on the side of the hoop unit away from the column 1; the hoop unit is used to enhance the deformation resistance of the column 1, and the lifting unit is used to adjust the distance between different hoop units; the hoop unit includes a transverse hoop 21 abutting against the outside of the column 1, two connecting sleeves 22 symmetrically fixedly connected to the two ends of the transverse hoop 21, and a positioning shaft 23 rotatably connected to the inner side of the connecting sleeve 22. , a swing arm 24 fixedly connected to the top of the positioning shaft 23, the top and bottom of the positioning shaft 23 are fixedly connected to the swing arm 24, a fixing seat 25 rotatably connected to the end of the swing arm 24 away from the positioning shaft 23, a sleeve 26 fixedly connected to the top of the fixing seat 25, a lifting hole 27 opened at the top of the sleeve 26, two guide rails 28 symmetrically fixedly connected to the inner wall of the lifting hole 27, a driven wheel 29 rotatably connected to the top of the sleeve 26, a screw hole 210 opened at the top of the driven wheel 29, a stud 211 meshingly connected to the inner side of the screw hole 210, and two guide grooves 212 symmetrically opened on both sides of the stud 211, the bottom of the stud 211 is slidably connected to the lifting hole 27, and the guide groove 212 is slidably connected to the guide rail 28.

[0039] Specifically, the fixing seat 25 is moved toward the column 1. When the fixing seat 25 moves, it drives the two swing arms 24 to move together. The swing arms 24 drive the cross hoop 21 to move through the shaft sleeve 26. When the cross hoop 21 contacts the surface of the cylinder, it will be squeezed by the cylinder and deformed, so that it fits the surface of the cylinder. Since the cross hoop 21 has the function of deformation, it can adapt to building components with arcs, planes and positive angles, thereby increasing the applicability of the device. By setting up the support mechanism 2, the building reinforcement device can adapt to building components with different shapes such as cylinders and walls to achieve a reinforcement effect. The design of the support mechanism 2 takes into account the geometric characteristics of different components, so that it can fit closely to the shapes of different building components. The flexibility of the support mechanism 2 enables it to adapt to components of different sizes and shapes, and a variety of reinforcement tasks can be completed without replacing the device. This design not only improves the versatility of the device, but also simplifies the construction process and reduces the complexity of operation.

[0040] Reference Figure 3 and Figure 4 The top of the stud 211 is fixedly connected to the fixing seat 25 of another hoop unit, the top of the sleeve 26 is stepped, and the bottom of the driven wheel 29 is provided with a stepped hole.

[0041] Specifically, a plurality of hoop units are connected end to end, the stepped hole of the driven wheel 29 is rotatably connected to the top of the shaft sleeve 26 , and the driven wheel 29 is constrained to be able to rotate only on the top of the shaft sleeve 26 .

[0042] Reference Figure 4 and Figure 6 The lifting unit includes a support block 213 fixedly connected to the side of the sleeve 26 away from the column 1, a limiting hole 214 opened at the top of the support block 213, a short shaft 215 rotatably connected to the inner side of the limiting hole 214, a hexagonal block 216 fixedly connected to the bottom of the short shaft 215, a driving wheel 220 fixedly connected to the top of the short shaft 215, a sleeve 217 fixedly connected to the top of the driving wheel 220, a polygonal hole 218 opened at the top of the sleeve 217, and a prism 219 slidably connected to the inside of the polygonal hole 218.

[0043] Specifically, the short shaft 215 and the driving wheel 220 can be driven by rotating the hexagonal block 216, and the driving wheel 220 drives the driven wheel 29 to rotate. The driven wheel 29 drives the stud 211 to rise and fall while rotating. The distance between different hoop units is adjusted by the lifting and lowering of the stud 211. The driving wheel 220 drives the sleeve 217 to rotate together while rotating. The sleeve 217 drives the prism 219 to rotate. The prism 219 drives another short shaft 215 and the driving wheel 220 at the top to rotate. The prism 219 can be lifted and lowered together with another hoop unit. Through the lifting unit, several hoop mechanisms can be driven to extend and retract at the same time. By setting the lifting unit, the building The reinforcement device can adapt to buildings of different heights and enhance the adaptability of the device. The design of the lifting unit enables it to be adjusted according to the actual height of the building, ensuring that the device can be stably installed in different scenarios. For taller buildings, the lifting unit can be expanded to provide sufficient support range; for lower buildings, the lifting unit can be contracted to avoid structural redundancy. The adjustability of the lifting unit enables it to flexibly respond to changes in building heights and complete a variety of reinforcement tasks without replacing the device, thereby improving the versatility of the device. By adjusting the position and length of the lifting unit, the device can fit closely to the building structure, ensuring the stability and consistency of the reinforcement effect.

[0044] Reference Figure 6 The cross section of the polygonal hole 218 is a regular hexagon, and the shape of the prism 219 matches the shape of the polygonal hole 218.

[0045] Specifically, the prism 219 can move up and down inside the polygonal hole 218 to accommodate the change in the distance between different hoop mechanisms.

[0046] Reference Figure 7-Figure 9 The fixing mechanism 3 includes a wall-mounted unit assembled at the bottom of the hoop unit, and an adjusting unit assembled at the top of the wall-mounted unit; the wall-mounted unit is used to fix the device on the side wall of the building, and the adjusting unit is used to adjust the prestress applied by the horizontal hoop 21 to the column 1; the wall-mounted unit includes a slider 31 fixedly connected to the bottom of the fixing seat 25, a base plate 32 slidably connected to the outside of the slider 31, a slide groove 33 opened at the top of the base plate 32, four bolts 34 symmetrically meshed and connected to the top of the base plate 32, and a stopper 35 fixedly connected to the base plate 32 on the side close to the fixing seat 25.

[0047] Specifically, the base plate 32 can be fixed on the ground or the wall by bolts 34 , and the slider 31 is constrained by the base plate 32 , and thus can only move linearly along the slide groove 33 , and drive the fixed seat 25 connected thereto to move synchronously.

[0048] Reference Figure 8 and Fig.12 The outer shape of the stopper 35 is a right triangle, and the height of the stopper 35 is the same as that of the fixing seat 25.

[0049] Specifically, the stopper 35 can limit the maximum stroke of the fixing seat 25 connected to the slider 31 so that the fixing seat 25 can move within a limited range.

[0050] Example 2, reference Figure 8-Figure 12 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the adjustment unit includes a horizontal axis 36 fixedly connected to the side of the base plate 32 away from the fixing seat 25, a shell 37 meshingly connected to the side of the horizontal axis 36 close to the fixing seat 25, a working chamber 38 opened at both ends of the shell 37, a plurality of annular arrays of exhaust holes 39 opened in the middle of the shell 37, a push rod 310 slidably connected to the side of the shell 37 close to the fixing seat 25, and the end of the push rod 310 away from the shell 37 is fixed to the fixing block. A blind hole 311 is provided on the side of the push rod 310 close to the outer shell 37, a guide column 312 is fixedly connected to the side of the horizontal axis 36 close to the push rod 310, one end of the guide column 312 away from the horizontal axis 36 is slidably connected to the blind hole 311, a rubber sleeve 313 is sleeved on the outside of the guide column 312, and the two ends of the rubber sleeve 313 are respectively abutted against the horizontal axis 36 and the push rod 310; and a spring 314 is sleeved on the outside of the rubber sleeve 313, and the two ends of the spring 314 are respectively fixedly connected to the horizontal axis 36 and the push rod 310.

[0051] Specifically, the spring 314 applies a force to the push rod 310, and the push rod 310 transmits the force to the fixed seat 25 connected thereto, and the fixed seat 25 drives the swing arm 24 connected thereto to move together, and the swing arm 24 drives the cross hoop 21 to move through the shaft sleeve 26, and fits the cross hoop 21 to the surface of the column 1, and the shell 37 can be moved horizontally under the action of the thread by rotating the shell 37. When the shell 37 moves toward the direction of the horizontal axis 36, it will drive the push rod 310 to move synchronously. At this time, the push rod 310 will squeeze the spring 314, and the push rod 310 drives the fixed seat 25 and the cross hoop 21 to move together. At this time, the prestress applied by the device on the column 1 will be reduced, and the shell 37 will move toward When the push rod 310 moves in the opposite direction, the force of the spring 314 will be fully applied to the push rod 310, and the push rod 310 will transfer the force to the column 1 through the fixing seat 25 and the cross hoop 21. Therefore, the prestress applied to the column 1 by the device will increase. When the earthquake causes the column 1 to vibrate and elastically deform, the energy released by the column 1 will be applied and transferred to the fixing seat 25 through the ring hoop, and the fixing seat 25 will transfer the energy to the push rod 310. The push rod 310 squeezes the spring 314 and the rubber sleeve 313, and the rubber sleeve 313 consumes energy through elastic deformation. The spring 314 will push the push rod 310 to reset after the column 1 finishes releasing the energy. The exhaust hole 39 can keep the air pressure inside the working chamber 38 consistent with the outside world.

[0052] Reference Figure 8-Figure 12 A thread is provided on one side of the horizontal axis 36 close to the housing 37 , and a threaded hole is provided on one side of the working chamber 38 close to the ejector rod 310 .

[0053] Specifically, rotating the housing 37 can make it move along the horizontal axis 36 under the action of the thread, thereby changing the prestress applied by the device on the column 1. The rest of the structure is the same as that of Example 1.

[0054] In summary, the working principle of the present invention is as follows: the housing 37 is rotated to move it toward the direction close to the horizontal axis 36 to the maximum stroke, and then the hexagonal block 216 is rotated. While the hexagonal block 216 is rotating, the driven wheel 29 is driven to rotate through the driving wheel 220, and the prism 219 is driven to rotate through the sleeve 217. The prism 219 drives the driving wheel 220 connected to another hoop unit to rotate, and so on. By rotating the hexagonal block 216, the driven wheels 29 in different hoop units can be driven to rotate synchronously. The driven wheels 29 rotate The stud 211 is driven to move up and down at the same time. The stud 211 is constrained by the guide rail 28 and the guide groove 212, so it can only move up and down vertically. When the stud 211 rises, the distance between different hoop units increases. When the stud 211 descends, the distance between different hoop units decreases, thereby controlling the height of the entire device. After the height of the device is adapted to the height of the column 1, the device is moved toward the column 1, so that the cross hoop 21 is attached to the surface of the column 1, and the two base plates 32 are fixed to the two base plates 32 by bolts 34. The housing 37 is rotated to move toward the top rod 310, so that the force of the spring 314 is applied to the column 1 through the top rod 310 and the hoop unit. By adjusting the position of the housing 37, the prestress applied to the column 1 can be adjusted. The more the housing 37 moves toward the top rod 310, the less force the housing 37 shares for the top rod 310, and the more force the spring 314 applies to the column 1 through the top rod 310. When the energy of the earthquake is transmitted to the column 1, , column 1 releases energy through vibration and deformation. The energy released by the vibration and deformation of column 1 will be transmitted to top rod 310 through the hoop unit, causing top rod 310 to displace, thereby squeezing spring 314 and rubber sleeve 313. Rubber sleeve 313 absorbs and consumes the energy released by column 1 through elastic deformation. Spring 314 drives top rod 310 to reset, allowing the device to restore support and reinforcement of column 1. The device increases the rigidity of column 1 through reinforcement, reduces the risk of structural damage to column 1 by consuming energy, and increases the safety of the building.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
