Description

Technical Field

[0001] This invention belongs to the field of seismic reinforcement technology, and particularly relates to a seismic reinforcement structure for reinforced concrete frames and its seismic reinforcement method. Background Technology

[0002] Reinforced concrete structures refer to structures made of concrete reinforced with steel bars. In order to cope with sudden events such as earthquakes and typhoons, it is necessary to add corresponding seismic strengthening devices to protect the reinforced concrete frame structure, so as to improve the overall seismic strengthening performance of the reinforced concrete frame structure and thus better cope with sudden events such as earthquakes and typhoons. At present, there are two methods to add seismic strengthening to reinforced concrete frames: one is to add seismic strengthening structures on the inside of the reinforced concrete frame, and the other is to add seismic strengthening structures on the outside of the reinforced concrete frame.

[0003] However, existing technologies have some problems: Currently, when adding seismic reinforcement structures to the outside of reinforced concrete frames, the general approach is to align and splice the components, then weld them at specific points. Since there are many seismic reinforcement steel plates around the load-bearing columns, the number of welding points increases to ensure stability. This makes seismic reinforcement of a single load-bearing column time-consuming and labor-intensive, hindering convenient and rapid reinforcement. Furthermore, the stability of the welding is highly dependent on the skill of the workers, making it impossible to guarantee that every weld point is seamless, thus presenting certain limitations. Additionally, with this method of splicing and then welding, when the beams drop, the vertical downward pressure on these welded seismic reinforcement structures can prevent them from accurately releasing pressure onto the reinforced concrete frame, causing the overall structure to easily bend and deform outwards. This hinders the improvement of the seismic stability of the reinforced concrete frame, thus presenting certain limitations. Therefore, we propose a seismic reinforcement structure and method for reinforced concrete frames. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a seismic strengthening structure and method for reinforced concrete frames. By adjusting the components and fastening components, the strengthening frame can be quickly installed on the outside of the reinforced concrete frame without welding, thereby improving the installation efficiency and seismic strengthening performance of the seismic strengthening structure applied to the reinforced concrete frame. At the same time, the design of the snap-fit ​​components can effectively prevent the strengthening frame from bending outward and causing deformation, thus effectively improving the seismic strengthening performance of the reinforced concrete frame.

[0005] This invention is implemented as follows: a reinforced concrete frame seismic strengthening structure, comprising:

[0006] The reinforced frame consists of several sets, each set consisting of four sets of corner anti-seismic plates. Each set of corner anti-seismic plates has right-angle grooves on opposite sides for fitting the load-bearing columns. Adjustment components are movably connected to the two ends of opposite sides of two adjacent sets of corner anti-seismic plates. The corner anti-seismic plates are movably connected to the reinforced plates through the adjustment components. Each set of corner anti-seismic plates has a snap-fit ​​component at its bottom, and the multiple sets of reinforced frames are spliced ​​together vertically through the snap-fit ​​components.

[0007] The fastening components are provided in several groups and are located at the ends of the reinforcing plates. Each reinforcing plate corresponds to one fastening component, and a connecting component is provided between every two groups of fastening components. Each two groups of fastening components form a fastening assembly by cooperating with the connecting component. The two groups of reinforcing plates are detachably set by the fastening assembly.

[0008] Optionally, the adjusting assembly includes an adjusting screw, an adjusting block is threadedly connected to the outside of the adjusting screw, and the adjusting block is rotatably connected to the reinforcing plate. The adjusting screw is movably installed inside the slide groove.

[0009] Optionally, both ends of the adjusting screw are rotatably connected to sliders, and the sliders are slidably installed in the slide groove. One end of the adjusting screw is fixedly installed with a rotating rod, and the rotating rod passes through one side of one set of sliders. One side of one set of sliders is provided with a rotating hole, and one side of the slide groove is provided with a clearance groove. The interior of the clearance groove is connected to the interior of the slide groove, and the rotating rod is correspondingly arranged inside the clearance groove.

[0010] Optionally, the adjusting block consists of a rotating sleeve and an adjusting nut, with the rotating sleeve fixedly installed on the outside of the adjusting nut. The rotating block is fixedly installed on one end of the reinforcing plate, and a movable hole is opened on one side of the rotating block. The rotating sleeve is rotatably installed inside the movable hole. The adjusting nut is threadedly connected to the adjusting screw. Sliding rods are fixedly installed at both ends between the two sets of sliders, and the two sets of sliding rods pass through both ends of one side of the adjusting nut. Sliding holes are opened at both ends of one side of the adjusting nut.

[0011] Optionally, the snap-fit ​​assembly includes two sets of snap-fit ​​blocks, which are symmetrically fixedly installed on the bottom of the corner anti-vibration plate. The bottom of both sets of snap-fit ​​blocks is triangular, and the lower end of one side of both sets of snap-fit ​​blocks is inclined. The upper surface of the corner anti-vibration plate is provided with a snap-fit ​​groove, and both sets of snap-fit ​​blocks are slidably inserted into the snap-fit ​​groove.

[0012] Optionally, one side of the snap-fit ​​groove is inclined, and a limiting groove is formed in the middle of one side of the snap-fit ​​groove. A limiting rod is fixedly installed between the two sets of snap-fit ​​blocks, and the lower end of the limiting rod is slidably inserted into the limiting groove.

[0013] Optionally, the fastening component includes a fastening screw, and a positioning block is threadedly connected to the outside of the fastening screw. A threaded hole is provided on one side of the positioning block, and a storage groove is provided at the end of the upper surface of the reinforcing plate away from the corner shock-absorbing plate, and the positioning block is slidably installed inside the storage groove.

[0014] Optionally, the connecting component includes a threaded block and a threaded sleeve. The opposite ends of the two sets of fastening screws are respectively fixedly connected to the threaded block and the threaded sleeve, and the threaded block is threadedly connected to the inside of the threaded sleeve. Both sets of fastening screws have fastening nuts threadedly connected to their outer sides.

[0015] A seismic strengthening method for reinforced concrete frames includes the following steps:

[0016] S1. Select a reinforced concrete frame that needs to be seismically reinforced;

[0017] S2. Prepare earthquake-resistant reinforcement materials;

[0018] S3. Attach the four corner anti-seismic plates to the four right-angled surfaces of the reinforced concrete frame, and splice the four corner anti-seismic plates together using fastening components.

[0019] S4. Repeat steps S1 to S3 to form multiple reinforced frames. Then, use snap-fit ​​components to perform upper and lower compression splicing to complete the seismic reinforcement installation of the reinforced concrete frame.

[0020] Optionally, step S3 includes the following steps:

[0021] S31. Fit the right-angle grooves opened on opposite sides of the four sets of corner seismic plates into the reinforced concrete frame.

[0022] S32. The reinforcing plates that are movably connected on opposite sides of each pair of corner seismic plates are rotated and rotated to a horizontal angle. Then, the two sets of reinforcing plates are connected by fastening components, and the corner seismic plates are controlled to fit tightly against the reinforced concrete frame by fastening components.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. Because the two sets of reinforcement plates are designed to be detachable via fastening components, they can be gradually brought closer together, allowing the corner seismic plates to better fit the reinforced concrete frame. Therefore, when seismically reinforcing the reinforced concrete frame, the installation can be completed by rotating multiple bolts. Furthermore, the positions of the corner seismic plates in multiple locations can be adjusted freely, eliminating the need for custom-made seismic reinforcement structures from the manufacturer and saving costs. Additionally, the elimination of multiple welding points reduces the cost for technical personnel and avoids defective products during welding, thus effectively improving the efficiency and stability of the seismic reinforcement installation of the reinforced concrete frame.

[0025] 2. Because multiple sets of reinforced frames are designed to be spliced ​​together vertically via snap-fit ​​components, when the upper reinforced frame is pressed downwards, the snap-fit ​​components utilize the shape and properties of the limiting groove and snap-fit ​​groove, in conjunction with the snap-fit ​​block and limiting rod, to transform the downward pressing force into the force of pressing the reinforced concrete frame. Therefore, it can effectively prevent the reinforced frame from bending, thereby effectively improving the seismic resistance of the reinforced concrete frame.

[0036] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0037] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0038] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0039] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0040] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0041] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0042] like Figures 1 to 8 As shown in the figure, an embodiment of the present invention provides a reinforced concrete frame seismic reinforcement structure, including: a reinforcement frame, which is provided in several groups, and each of the several groups of reinforcement frames is composed of four groups of corner seismic plates 1, and each of the four groups of corner seismic plates 1 has right-angle grooves on opposite sides for fitting the reinforced concrete frame, and each end of the opposite sides of two adjacent groups of corner seismic plates 1 is movably connected to an adjustment component 4, and the corner seismic plates 1 are movably connected to a reinforcement plate 5 through the adjustment component 4, and each of the several groups of corner seismic plates 1 has a snap-fit ​​component 2 at the bottom, and the multiple groups of reinforcement frames are spliced ​​together vertically through the snap-fit ​​component 2;

[0043] It is worth noting that the overall shape of the reinforced concrete frame mentioned above is rectangular;

[0044] Because the reinforced frame is designed to consist of four sets of corner seismic plates 1, each of the four sets of corner seismic plates 1 can better fit the reinforced concrete frame through its own right-angle grooves, thereby effectively improving the stability when connected to the reinforced concrete frame.

[0045] Because the corner seismic plate 1 is movably connected to the reinforcement plate 5 through the adjustment component 4, the position of the reinforcement plate 5 can be adjusted at will, thereby strengthening the weaker seismic performance of the reinforced concrete frame. Therefore, the seismic performance of the reinforced concrete frame can be effectively improved.

[0046] Because multiple sets of reinforcing frames are designed to be spliced ​​together vertically via snap-fit ​​components 2, the multiple sets of reinforcing frames can be fixed by snap-fit ​​components 2. If the upper reinforcing frame is compressed, snap-fit ​​components 2 can effectively prevent the reinforcing frame from bending and deforming by utilizing its own characteristics.

[0047] Fastening components are provided in several groups and are located at the ends of the reinforcing plates 5. Each reinforcing plate 5 corresponds to a fastening component, and a connecting component is provided between every two groups of fastening components. Each two groups of fastening components form a fastening assembly 9 by cooperating with the connecting component. The two groups of reinforcing plates 5 are detachably set by the fastening assembly 9.

[0048] Because the two sets of reinforcing plates 5 are designed to be detachable via fastening components 9, it is worth noting that the two sets of reinforcing plates 5 mentioned above refer to the reinforcing plates 5 on opposite sides of the two adjacent sets of corner seismic plates 1. When the two sets of corner seismic plates 1 need to be fixed to the reinforced concrete frame, the two adjacent sets of corner seismic plates 1 can be gradually brought closer together via fastening components 9, thus eliminating the need to fix them to the reinforced concrete frame by welding, thereby improving the installation efficiency of applying seismic reinforcement to the reinforced concrete frame.

[0049] Furthermore, the adjustment assembly 4 includes an adjustment screw 403, an adjustment block 405 is threadedly connected to the outside of the adjustment screw 403, and the adjustment block 405 is rotatably connected to the reinforcing plate 5. The adjustment screw 403 is movably installed inside the slide groove. Both ends of the adjustment screw 403 are rotatably connected to sliders 402, and the sliders 402 are slidably installed in the slide groove. A rotating rod 404 is fixedly installed at one end of the adjustment screw 403, and the rotating rod 404 passes through one side of one set of sliders 402. A rotating hole is opened on one side of one set of sliders 402, and a clearance groove 3 is opened on one side inside the slide groove. The interior of the clearance groove 3 is interconnected with the interior of the slide groove, and the rotating rod 404 is correspondingly arranged inside the clearance groove 3.

[0050] With the slider 402 slidably installed inside the slide groove, the adjusting screw 403 can drive the reinforcing plate 5 to move up and down freely in the slide groove through the adjusting block 405. Therefore, the reinforcing plate 5 can move up and down in the slide groove. At the same time, the reinforcing plate 5 can rotate, so that when transporting the reinforcing frame, the reinforcing plate 5 can be rotated and stored in the slide groove, reducing the space occupied, thus facilitating transportation and carrying, and improving its practicality.

[0051] Meanwhile, by adjusting the screw 403 and adjusting the block 405, the reinforcing plate 5 can be brought closer to the reinforced concrete frame through the cooperation of the adjusting block 405 and the adjusting screw 403, thereby further improving the stability of the reinforced concrete frame and the stability of the corner seismic plate 1 when it is installed on the reinforced concrete frame.

[0052] Furthermore, the adjusting block 405 is composed of a rotating sleeve 4051 and an adjusting nut 4052, with the rotating sleeve 4051 fixedly installed on the outside of the adjusting nut 4052. The rotating block 401 is fixedly installed on one end of the reinforcing plate 5, and a movable hole is opened on one side of the rotating block 401. The rotating sleeve 4051 is rotatably installed inside the movable hole. The adjusting nut 4052 is threadedly connected to the adjusting screw 403. Sliding rods 14 are fixedly installed at both ends between the two sets of sliders 402, and the two sets of sliding rods 14 pass through both ends of one side of the adjusting nut 4052. Sliding holes 11 are opened at both ends of one side of the adjusting nut 4052.

[0053] By adjusting the nut 4052 and the adjusting screw 403 in a threaded connection, the adjusting screw 403 can drive the reinforcing plate 5 to approach the reinforced concrete frame during rotation, thereby completing the connection between the two adjacent sets of corner seismic plates 1 and the reinforced concrete frame. This eliminates the need for welding for installation and fixation, which reduces air pollution and welding costs to a certain extent.

[0054] Because the two sets of sliding rods 14 are designed to pass through both ends of one side of the adjusting nut 4052, the sliding rods 14 can improve the stability of the adjusting nut 4052 when it moves as the adjusting screw 403 drives it, thus avoiding the situation where the adjusting nut 4052 cannot move between the two sets of sliders 402.

[0055] Furthermore, the snap-fit ​​assembly 2 includes two sets of snap-fit ​​blocks 203, which are symmetrically fixedly installed at the bottom of the corner anti-seismic plate 1. The bottom of both sets of snap-fit ​​blocks 203 is triangular, and the lower end of one side of both sets of snap-fit ​​blocks 203 is inclined. A snap-fit ​​groove 201 is opened on the upper surface of the corner anti-seismic plate 1, and both sets of snap-fit ​​blocks 203 are slidably inserted into the snap-fit ​​groove 201. One side of the snap-fit ​​groove 201 is inclined, and a limiting groove 202 is opened in the middle of one side of the snap-fit ​​groove 201. A limiting rod 204 is fixedly installed between the two sets of snap-fit ​​blocks 203, and the lower end of the limiting rod 204 is slidably inserted into the limiting groove 202.

[0056] With the design that the lower ends of both sets of snap-fit ​​blocks 203 are inclined, when the corner seismic plate 1 is pressed and moves downward, the snap-fit ​​block 203 can rely on the inclined angle of the bottom to gradually approach the reinforced concrete along the inclined angle inside the snap-fit ​​groove 201, so as to avoid the corner seismic plate 1 from bending outward, thereby effectively improving the seismic performance of the reinforced concrete frame.

[0057] Because the lower end of the limiting rod 204 is slidably inserted into the limiting groove 202, it is worth noting that the inner diameter of the limiting groove 202 is larger than that of the limiting rod 204, and one side of the outer periphery of the limiting rod 204 is perpendicular to one side of the inner periphery of the limiting groove 202. Therefore, when the snap-fit ​​block 203 approaches the reinforced concrete frame through the snap-fit ​​groove 201, the limiting rod 204 moves inside the limiting groove 202. Due to the internal structure of the limiting groove 202, the limiting rod 204 cannot move away from the reinforced concrete frame and can only approach it, thereby effectively improving the stability of the reinforced frame when it is subjected to pressure from above.

[0058] Furthermore, the fastening components include a fastening screw 901, and a positioning block 903 is threadedly connected to the outside of the fastening screw 901. A threaded hole is provided on one side of the positioning block 903. A storage groove 10 is provided at one end of the upper surface of the reinforcing plate 5 away from the corner anti-vibration plate 1, and the positioning block 903 is slidably installed inside the storage groove 10.

[0059] With the positioning block 903 slidably installed inside the storage groove 10, after the two sets of reinforcing plates 5 are connected by the fastening screw 901 and the connecting parts, in order to prevent the fastening screw 901 from being stripped by external interference, the fastening screw 901 can be slid into the storage groove 10 to avoid the stability of the connection between the corner seismic plate 1 and the reinforced concrete steel bars from being affected by external interference.

[0060] Specifically, such as Figure 4 and Figure 5As shown, protective plates 6 are slidably connected to the two sets of reinforcing plates 5 that are interconnected by fastening components 9. One set of protective plates 6 has a locking block 7 at one end, and the other set of protective plates 6 has a locking groove 8 at one end. The locking block 7 is locked into the locking groove 8. When the fastening screw 901 is slidably stored into the locking groove 8, the two sets of protective plates 6 can be interconnected to block the top of the storage groove 10, thereby effectively preventing external objects from entering the storage groove 10 and affecting the fastening screw 901. This can effectively improve the stability of the connection between the two sets of adjacent corner anti-vibration plates 1.

[0061] Furthermore, the connecting components include a threaded block 12 and a threaded sleeve 13. The opposite ends of the two sets of fastening screws 901 are fixedly connected to the threaded block 12 and the threaded sleeve 13 respectively, and the threaded block 12 is threadedly connected to the inside of the threaded sleeve 13. The outer sides of the two sets of fastening screws 901 are threadedly connected to fastening nuts 902.

[0062] By designing the threaded block 12 to be threaded inside the threaded sleeve 13, the rotation direction of the threaded block 12 and the threaded sleeve 13 is opposite to the rotation direction of the fastening screw 901 and the positioning block 903. Therefore, by rotating one set of fastening screws 901, the two sets of positioning blocks 903 can be controlled to move closer to each other, thus completing the fastening connection between the two adjacent sets of corner anti-seismic plates 1 and the reinforced concrete frame.

[0063] It is worth noting that when the corner seismic plate 1 is connected to the reinforced concrete frame, the stability of the connection between the two sets of reinforcement plates 5 can be further fixed by tightening the nuts 902, thereby effectively improving the stability of the seismic reinforcement of the reinforced concrete frame.

[0064] A seismic strengthening method for reinforced concrete frames includes the following steps:

[0065] S1. Select a reinforced concrete frame that needs to be seismically reinforced;

[0066] S2. Prepare earthquake-resistant reinforcement materials;

[0067] S3. The four corner seismic plates 1 are attached to the four right-angled surfaces of the reinforced concrete frame, and the four corner seismic plates 1 are spliced ​​together using fastening components 9.

[0068] S4. Repeat steps S1 to S3 to form multiple reinforced frames. Then, use snap-fit ​​components 2 to perform upper and lower compression splicing to complete the seismic reinforcement installation of the reinforced concrete frame.

[0069] Furthermore, S3 includes the following steps:

[0070] S31. Fit the right-angle grooves opened on opposite sides of the four sets of corner seismic plates 1 into the reinforced concrete frame.

[0071] S32. The reinforcing plates 5 that are movably connected on opposite sides of each pair of corner seismic plates 1 are rotated and rotated to a horizontal angle. Then, the two sets of reinforcing plates 5 are connected by fastening components 9, and the corner seismic plates 1 are tightly fitted to the reinforced concrete frame by fastening components 9.
