Abstract
Description
Technical Field
[0001] This invention relates to the field of reinforced concrete column technology, specifically to a reinforced concrete column reinforcement component and reinforcement method. Background Technology
[0002] Commercially available reinforced concrete column reinforcement components typically employ external fixing, meaning holes are drilled in the column surface and screws or expansion bolts are used to connect the reinforcement component to the column. However, when the column bends, these connections detach, rendering the reinforcement component ineffective in supporting the column against bending. This external fixing method neglects the reinforcement of the internal steel reinforcement cage, failing to provide simultaneous internal and external structural reinforcement, resulting in inadequate reinforcement. Therefore, we introduce a reinforced concrete column reinforcement component and method. Summary of the Invention
[0003] The purpose of this invention is to provide a reinforced concrete column reinforcement component and reinforcement method to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a reinforced concrete column reinforcement component, comprising a reinforced concrete column body and an outer frame fixed to the outside of the reinforced concrete column body, wherein the reinforced concrete column body includes a skeleton, a support frame disposed inside the skeleton, and a concrete layer formed by concrete poured on the skeleton and the support frame.
[0005] The support frame includes fixed frames on the upper and lower sides inside the skeleton and diagonal braces connected to the fixed frames. The middle screw between the upper and lower fixed frames is used to tighten and fix the upper and lower diagonal braces, so that the fixed frames support the middle of the side of the skeleton and the diagonal braces support the corners of the skeleton.
[0006] The outer frame includes a frame that fits onto the upper and lower parts of the outside of the reinforced concrete column body and a connecting frame that is fixed on the side between the upper and lower frames. The connecting frame is fixedly connected to one end of the fixing frame that extends out of the concrete layer, so that the outer frame is supported as a whole on the outer wall of the reinforced concrete column body.
[0007] The skeleton includes several sets of vertical steel bars arranged in a rectangular shape and rectangular stirrups that are sleeved and fixed to the outside of the several sets of vertical steel bars, and the adjacent rectangular stirrups are arranged at equal intervals.
[0008] Preferably, the fixing frame includes a cross support plate supported on the corresponding rectangular stirrups and a reinforcing rib frame connected at the right angle of the cross support plate. The first slot at the end of the cross support plate is engaged with the vertical steel bar in the middle of the side of the frame. The two ends of the first slot are provided with protrusions extending out of the concrete layer.
[0009] The diagonal bracing frame includes a connecting cylinder that runs through the middle of the cross support plate and diagonal bracing rods that are movably connected at equal intervals on the connecting cylinder, and the U-shaped positioning seat at the end of the diagonal bracing rod is engaged with the vertical steel bar at the corner.
[0010] The upper and lower sets of diagonal bracing frames are arranged symmetrically. The root of the diagonal bracing rod is movably connected to the slot on one side of the connecting cylinder by a pin. The other end of the connecting cylinder passes through the cross support plate and is connected to a limit nut.
[0011] Preferably, the two ends of the intermediate screw are screwed into the upper and lower sets of connecting cylinders. The nut fixed in the middle of the intermediate screw causes the upper and lower sets of connecting cylinders to move away from each other when the intermediate screw rotates clockwise, thereby causing the connecting cylinders to push the diagonal brace until the U-shaped positioning seat is in close contact with the corresponding rectangular stirrup.
[0012] Preferably, the connecting frame includes two sets of first abutting blocks and a grid-shaped frame, the grid-shaped frame including two sets of second abutting blocks and vertical plates fixed to the outer ends of the two sets of second abutting blocks;
[0013] The upper and lower sets of second abutment blocks are located between the two sets of first abutment blocks. The vertical plate is inserted into the slot on the outer side of the first abutment block. The two ends of the vertical plate are fixed to the corresponding outer side of the frame by the first bolt, so that the first abutment block and the second abutment block are in close contact with the side wall of the reinforced concrete column body.
[0014] A long screw rod runs through the two protruding blocks of the same group that protrude from the concrete layer, and the long screw rod is screwed and fixed to the corresponding second abutment block. The inner side of the middle of the first abutment block is provided with an avoidance groove for avoiding the long screw rod. The protruding block is inserted into the slot at the outer end of the avoidance groove, and a second bolt is screwed on the protruding block, which further fixes the connecting frame to the side wall of the reinforced concrete column body.
[0015] S1. Make the frame, fixing frame and diagonal brace. Fix the fixing frame inside the frame and set the diagonal brace on the corresponding fixing frame. Then tighten the middle screw between the upper and lower fixing frames to tighten and fix the upper and lower diagonal brace. This allows the fixing frame to support the middle of the side of the frame and the diagonal brace to support the corner of the frame.
[0016] S2. Pour concrete into the frame, fixing frame and diagonal bracing frame, and after the concrete is formed, the reinforced concrete column body is formed.
[0017] S3. Fit the frame onto the outside of the reinforced concrete column body, and fix the end of the connecting frame and the fixing frame that extends out of the concrete layer so that the frame and the connecting frame form a whole and are supported on the outer wall of the reinforced concrete column body.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The intermediate screw between the upper and lower sets of fixing frames is used to tighten and fix the upper and lower sets of diagonal bracing frames, so that the fixing frames are used to support the middle of the side of the frame, and the diagonal bracing frames are used to support the corners of the frame. This enables the support frame composed of the fixing frames and diagonal bracing frames to support the corners and the middle of the side of the frame, further improving the structural strength of the frame, preventing bending, and enhancing the seismic resistance of the reinforced concrete column body composed of the frame, support frame and concrete layer.
[0019] The outer frame fixed to the outside of the reinforced concrete column body includes a frame body that fits into the upper and lower parts of the outer side of the reinforced concrete column body and a connecting frame fixed between the upper and lower frames. The connecting frame is fixedly connected to the end of the fixing frame that extends out of the concrete layer, so that the outer frame will not move relative to the reinforced concrete column body in the left, right or up and down. Thus, the outer frame is supported as a whole on the outer wall of the reinforced concrete column body, and plays a supporting role for the reinforced concrete column body when it bends.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] Please see Figure 1-11 The present invention provides a technical solution:
[0034] Example 1:
[0035] A reinforced concrete column reinforcement component includes a reinforced concrete column body 7 and an outer frame fixed to the outside of the reinforced concrete column body 7. The reinforced concrete column body 7 includes a skeleton 1, a support frame disposed inside the skeleton 1, and a concrete layer formed by concrete poured on the skeleton 1 and the support frame.
[0036] The skeleton 1 includes several sets of vertical steel bars 101 arranged in a rectangular shape and rectangular stirrups 102 sleeved and fixed on the outside of the several sets of vertical steel bars 101, and the adjacent rectangular stirrups 102 are arranged at equal intervals.
[0037] The support frame includes a fixed frame 3 fixed inside the upper and lower sides of the frame 1 and a diagonal brace 2 connected to the fixed frame 3. The middle screw 5 between the upper and lower fixed frames 3 is used to tighten and fix the upper and lower diagonal braces 2, so that the fixed frame 3 is used to support the middle of the side of the frame 1 and the diagonal brace 2 is used to support the corner of the frame 1.
[0038] The fixing frame 3 includes a cross support plate 301 supported on the corresponding rectangular stirrups 102 and a reinforcing frame 303 connected at the right angle of the cross support plate 301. After the poured concrete has completely solidified, the reinforcement frame 303 can be used to further improve the firmness of the connection between the fixing frame 3 and the concrete layer, and further improve the structural strength of the reinforced concrete column body 7.
[0039] The first slot 302 at the end of the cross support plate 301 is engaged with the vertical steel bar 101 in the middle of the side of the frame 1. The two ends of the first slot 302 are provided with protrusions 304 extending out of the concrete layer.
[0040] The diagonal bracing frame 2 includes a connecting cylinder 201 that passes through the middle of the cross support plate 301 and diagonal bracing rods 203 that are movably connected at equal intervals on the connecting cylinder 201, and the U-shaped positioning seat 205 at the end of the diagonal bracing rod 203 is stuck on the vertical steel bar 101 at the corner.
[0041] The upper and lower sets of diagonal bracing frames 2 are arranged symmetrically. The root of the diagonal bracing rod 203 is movably connected to the slot 202 on one side of the connecting cylinder 201 through the pin 204. The other end of the connecting cylinder 201 passes through the cross support plate 301 and is connected to the limit nut 4.
[0042] After the middle screw 5 rotates clockwise, causing the upper and lower connecting cylinders 201 to move away from each other, the limiting nut 4 is set and locked on the cross support plate 301. At this time, the U-shaped positioning seat 205 at the end of the diagonal brace 203 is locked on the vertical steel bar 101 at the corner until the U-shaped positioning seat 205 is close to the corresponding rectangular stirrup 102.
[0043] After rotating the limit nut 4, the length of the connecting cylinder 201 extending through the cross support plate 301 can be adjusted. After the middle screw 5 is rotated clockwise, the opening angle of the diagonal brace 203 can be adjusted, so that the U-shaped positioning seat 205 at the end of the diagonal brace 203 can be accurately locked on the vertical steel bar 101 at the corner until the U-shaped positioning seat 205 is tightly attached to the corresponding rectangular stirrup 102.
[0044] This configuration makes it convenient and quick to support and fix the diagonal brace 2 to the frame 1, and meets the requirements of the diagonal brace 2 to support and fix the frame 1 of different sizes.
[0045] The two ends of the intermediate screw 5 are screwed into the upper and lower sets of connecting cylinders 201. The nut 6 fixed in the middle of the intermediate screw 5 is turned by a wrench, which causes the intermediate screw 5 to rotate. When the intermediate screw 5 rotates clockwise, the upper and lower sets of connecting cylinders 201 move away from each other, thereby causing the connecting cylinders 201 to push the diagonal brace 203 until the U-shaped positioning seat 205 is in close contact with the corresponding rectangular stirrup 102.
[0046] The outer frame includes a frame 10 fitted onto the upper and lower parts of the outside of the reinforced concrete column body 7 and a connecting frame fixed between the upper and lower frames 10. The connecting frame is fixedly connected to one end of the fixing frame 3 that extends out of the concrete layer, so that the outer frame is supported as a whole on the outer wall of the reinforced concrete column body 7.
[0047] The connecting frame includes two sets of first abutting blocks 9 and a grid-shaped frame 13. The grid-shaped frame 13 includes two sets of second abutting blocks 131 and vertical plates 132 fixed to the outer ends of the two sets of second abutting blocks 131.
[0048] The upper and lower sets of second abutment blocks 131 are located between the two sets of first abutment blocks 9. The vertical plate 132 is inserted into the slot 93 on the outer side of the first abutment block 9. The two ends of the vertical plate 132 are fixed to the outer side of the corresponding frame 10 by the first bolt 12, so that the first abutment block 9 and the second abutment block 131 are in close contact with the side wall of the reinforced concrete column body 7.
[0049] A long screw 8 passes through the two protruding blocks 304 of the same group extending out of the concrete layer, and the long screw 8 is screwed and fixed to the corresponding second abutment block 131. The inner side of the middle of the first abutment block 9 is provided with an avoidance groove 91 for avoiding the long screw 8. The protruding block 304 is inserted into the slot 92 at the outer end of the avoidance groove 91, and a second bolt 11 is screwed on the protruding block 304, which further fixes the connecting frame to the side wall of the reinforced concrete column body 7.
[0050] This invention also provides a reinforcement method for a reinforced concrete column reinforcement component, specifically including the following steps:
[0051] S1. Make a frame 1, a fixing frame 3 and a diagonal brace 2. Fix the fixing frame 3 inside the frame 1 and set the diagonal brace 2 on the corresponding fixing frame 3. Then tighten the middle screw 5 between the upper and lower fixing frames 3 to tighten and fix the upper and lower diagonal braces 2, so that the fixing frame 3 is used to support the middle side of the frame 1 and the diagonal brace 2 is used to support the corner of the frame 1.
[0052] S2. Pour concrete on the frame 1, the fixing frame 3 and the diagonal brace 2, and after the concrete is formed, a reinforced concrete column body 7 is formed.
[0053] S3. Fit the frame 10 onto the outside of the reinforced concrete column body 7, and fix the end of the connecting frame and the fixing frame 3 that extends out of the concrete layer so that the frame 10 and the connecting frame form an integral support on the outer wall of the reinforced concrete column body 7.
[0054] Specifically, in use, the rectangular stirrups 102 are sleeved on the outside of several groups of rectangularly distributed vertical steel bars 101. The adjacent rectangular stirrups 102 are set at equal intervals, and the connection between the rectangular stirrups 102 and the vertical steel bars 101 is connected and fixed by tie wire, so that the vertical steel bars 101 at the corner are fixed at the corner inside the rectangular stirrups 102.
[0055] The cross support plate 301 is tilted and placed into the frame 1. Then, the first slot 302 at the end of the cross support plate 301 is locked onto the vertical steel bar 101 in the middle of the side of the frame 1, so that the cross support plate 301 is in a horizontal state and the upper and lower sets of cross support plates 301 are arranged symmetrically.
[0056] The connecting cylinder 201 passes through the middle of the cross support plate 301. The root of the diagonal brace 203 is movably connected to the slot 202 on one side of the connecting cylinder 201 through the pin 204. The other end of the connecting cylinder 201 passes through the cross support plate 301 and is connected to the limit nut 4.
[0057] Then tighten the middle screw 5 between the upper and lower sets of fixing frames 3 to tighten and fix the upper and lower sets of diagonal bracing frames 2. At this time, the fixing frame 3 abuts against the corresponding rectangular stirrup 102, and the U-shaped positioning seat 205 at the end of the diagonal bracing rod 203 is stuck on the vertical steel bar 101 at the corner until the U-shaped positioning seat 205 is tightly attached to the corresponding rectangular stirrup 102.
[0058] The upper and lower sets of diagonal bracing frames 2 are tightened and fixed, so that the fixing frame 3 is used to support the middle of the side of the frame 1, and the diagonal bracing frames 2 are used to support the corners of the frame 1.
[0059] Then, the reinforcing rib frame 303 is welded and fixed at the right angle of the cross support plate 301. Concrete is poured on the frame 1, the fixing frame 3 and the diagonal brace 2. After the concrete is formed, the reinforced concrete column body 7 is formed.
[0060] The frame 10 is fitted onto the outside of the reinforced concrete column body 7. Then, the first abutment block 9 is locked and fixed to the protrusion block 304 by the second bolt 11. The protrusion block 304 is inserted into the slot 92 at the outer end of the relief groove 91. After the second bolt 11 is locked, the first abutment block 9 is pressed tightly against the outer wall of the reinforced concrete column body 7.
[0061] The two ends of the vertical plate 132 of the grid frame 13 are fixed to the outer side wall of the corresponding frame 10 by the first bolt 12. After the first bolt 12 is tightened, the vertical plate 132 is locked in the slot 93 on the outer side of the first abutment block 9 (this can prevent the grid frame 13 from moving left and right relative to the reinforced concrete column body 7). The second abutment block 131 is close to the outer side wall of the reinforced concrete column body 7.
[0062] Then, a long screw 8 is inserted between the two protrusions 304 in the same group, and the long screw 8 is screwed and fixed to the corresponding second abutment block 131, so as to prevent the grid frame 13 from moving up and down relative to the reinforced concrete column body 7.
[0063] A common practice is to drill holes in the surface of the reinforced concrete column body 7 and use screws and expansion bolts to connect with the holes in the surface of the reinforced concrete column body 7 to fix the outer frame to the reinforced concrete column body 7. However, when the reinforced concrete column body 7 bends, the screws and expansion bolts will detach from the connection with the holes in the surface of the reinforced concrete column body 7, making it impossible for the outer frame to provide support and reinforcement for the bent reinforced concrete column body 7.
[0064] The connection between the outer frame of the reinforced concrete column reinforcement component and the reinforced concrete column body 7 does not require drilling holes on the surface of the reinforced concrete column body 7. The connecting frame and the end of the fixing frame 3 that extends out of the concrete layer are fixedly connected, so that the frame 10 and the connecting frame form an integral support on the outer wall of the reinforced concrete column body 7, and the connection between the outer frame and the reinforced concrete column body 7 is firm and stable.
[0065] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
