Description

Technical Field

[0001] This application relates to the technical field of reinforced concrete structures, and in particular to a modified reinforced concrete structure for a frame column-beam-column joint. Background Technology

[0002] Parallel reinforcement refers to the arrangement of two or more steel bars together to solve the design and construction difficulties caused by the inability to obtain steel bars of sufficient diameter and dense reinforcement. Parallel reinforcement can increase the tensile bearing capacity of concrete structures because the parallel use of steel bars is equivalent to increasing the area of ​​the tension zone. Parallel reinforcement can improve the stability of the structure, especially when subjected to large loads or dynamic actions.

[0003] During the reinforcement construction process, the reinforcement in the beam-column joint area is dense, especially in the columns in the middle. The beam and column reinforcements are crisscrossed. The longitudinal reinforcement of the beam should be placed inside the longitudinal reinforcement of the column, forming a grid pattern. The spacing between the beam and column joints of ordinary frame columns is relatively large. If beam reinforcement is installed at the beam-column joint, there is sufficient space for the column reinforcement spacing, and the installation of beam reinforcement is easy to achieve.

[0004] If the frame column has parallel reinforcement bars, the space occupied by the parallel reinforcement bars is large, resulting in a small spacing between the two parallel reinforcement bars. This can lead to situations where the beam reinforcement bars cannot be installed between the two parallel reinforcement bars or are difficult to install, which can easily cause problems with the installation quality of beam and column reinforcement bars. Summary of the Invention

[0005] To facilitate the smoother installation of beam reinforcement between two parallel bars, this application provides a modified parallel bar structure for beam-column joints in frame columns.

[0006] This application provides a modified reinforcement structure for a frame column-beam-column joint, employing the following technical solution:

[0007] A modified reinforcement structure for a frame column-beam joint includes four corner bars arranged in a rectangular pattern. Stirrups are fitted onto the outer walls of the four corner bars. Multiple first longitudinal bars are provided on the two inner walls of the stirrups along the X-axis, with the long side of the cross-section of each first longitudinal bar parallel to the Y-axis. Multiple second longitudinal bars are provided on the two inner walls of the stirrups along the Y-axis, with the long side of the cross-section of the multiple second longitudinal bars on one side of the inner wall of the stirrups parallel to the Y-axis.

[0008] By adopting the above technical solution, the beam reinforcement passes through the stirrups, with the long side of the beam reinforcement parallel to the Y-axis. The beam reinforcement passes through the space between two adjacent first longitudinal reinforcements, with the long side of the cross-section of the first longitudinal reinforcement parallel to the Y-axis. Compared to the case where the long side of the cross-section of the first longitudinal reinforcement is parallel to the X-axis, this application can reduce the space occupied by the stirrups in the X-axis direction. The long sides of the cross-sections of multiple second longitudinal reinforcements on one side of the stirrup inner wall in the Y-axis direction are parallel to the Y-axis. Compared to the case where the long sides of the cross-sections of multiple second longitudinal reinforcements on both sides of the stirrup are parallel to the X-axis, this application can increase the space in the X-axis direction within the stirrup frame, thereby providing more space for the beam reinforcement to pass through.

[0009] This application correspondingly increases the space in the X-axis direction within the stirrups, thereby increasing the space for the beam reinforcement to pass through, making it easier to install the beam reinforcement between the two first longitudinal bars, thus accelerating the project progress and shortening the construction period.

[0010] Preferably, two adjacent first longitudinal ribs form a first longitudinal rib group, and the outer walls of the two corresponding first longitudinal rib groups are respectively fitted with connecting ribs, which connect the four first longitudinal ribs, and the long side of the connecting rib is parallel to the Y-axis direction.

[0011] By adopting the above technical solution, under the action of the connecting bar, the connecting bar can limit the position of the four first longitudinal bars. The outer wall of the first longitudinal bar abuts against the inner wall of the connecting bar, so that the line connecting two opposite first longitudinal bars is parallel to the Y-axis direction, thereby enhancing the overall stability and rigidity of the frame column. At the same time, during the concrete pouring process, the displacement of the first longitudinal bars during the pouring process can be reduced.

[0012] Preferably, two adjacent second longitudinal ribs form a second longitudinal rib group, and the outer walls of the two corresponding second longitudinal rib groups are respectively fitted with fixing ribs, which connect the four second longitudinal ribs, and the long side of the fixing rib is parallel to the X-axis direction.

[0013] By adopting the above technical solution, the four second longitudinal bars can be limited under the action of the fixing bars, which can enhance the overall stability and rigidity of the frame column and reduce the displacement of the second longitudinal bars during the pouring process.

[0014] Preferably, the long sides of the plurality of second longitudinal bars on the other side of the inner wall of the stirrup in the Y-axis direction are parallel to the long side of the fixing bar.

[0015] By adopting the above technical solution, the long side of the cross-section of multiple second longitudinal bars on one side of the inner wall of the stirrup in the Y-axis direction is parallel to the long side of the fixed bar, thereby making the contact area between the outer wall of the second longitudinal bar and the long side of the fixed bar larger, so as to better limit the four second longitudinal bars.

[0016] Preferably, the corner reinforcement includes two steel bars, and a fastening component is provided between the outer walls of the two steel bars, the fastening component being used to limit the two steel bars.

[0017] By adopting the above technical solution, the fastening component limits the two steel bars before welding them together. Under the action of the fastening component, the two steel bars can be limited, so that the two steel bars are in a vertically close state, which makes it easier for construction personnel to weld the two steel bars.

[0018] Preferably, the fastening assembly includes a limiting box, and a placement groove is provided through one side of the limiting box, into which two steel bars are fitted and inserted.

[0019] By adopting the above technical solution, under the action of the limiting box, the two steel bars are fitted into the limiting box, the outer wall of the steel bars abuts against the inner wall of the box, and the outer walls of the two steel bars abut against each other, thereby limiting the two steel bars.

[0020] Preferably, the fastening assembly further includes a connecting plate, the side wall of which is fixed to one side of the limiting box, and one side of which abuts against the outer wall of the reinforcing bar.

[0021] By adopting the above technical solution, the connection area between the connecting plate and the reinforcing bar can be increased, thereby improving the connection stability between the limiting box and the reinforcing bar. At the same time, it can also reduce the situation where the two reinforcing bars slip out or deviate from the placement groove.

[0022] Preferably, there are two fastening components, which are distributed at the top and bottom of the reinforcing bar.

[0023] By adopting the above technical solution, two fastening components are distributed at the top and bottom of the reinforcing bar, thereby limiting the top and bottom of the reinforcing bar and allowing the two reinforcing bars to fit together better.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The beam reinforcement passes through the stirrups, with the long side of the beam reinforcement parallel to the Y-axis. The beam reinforcement passes through the space between two adjacent first longitudinal reinforcement bars. This application correspondingly increases the space in the X-axis direction within the stirrups, thereby increasing the space for the beam reinforcement to pass through. This makes it easier to install the beam reinforcement between the two first longitudinal reinforcement bars, which can speed up the project progress and shorten the construction period.

[0026] 2. After the fastening component limits the two reinforcing bars, the two reinforcing bars are welded together. Under the action of the fastening component, the two reinforcing bars can be limited, so that the two reinforcing bars are in a vertically close state, which makes it easier for construction personnel to weld the two reinforcing bars.

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a modified reinforcement structure for a frame column-beam-column joint.

[0033] Reference Figure 1 and Figure 2 A modified reinforcement structure for a frame column-beam joint includes corner reinforcement 1, each corner reinforcement 1 comprising two vertically arranged steel bars 11. A fastening assembly 2 is provided between the outer walls of the two steel bars 11. The fastening assembly 2 includes a limiting box 21 and a connecting plate 22. A placement groove is provided through one side of the limiting box 21. The placement groove is rectangular and its length is consistent with the sum of the diameters of the two steel bars 11. The width of the placement groove is consistent with the diameter of the steel bars 11, allowing the two steel bars 11 to fit snugly into the placement groove. The outer walls of the steel bars 11 abut against the inner wall of the placement box. Under the action of the limiting box 21, the two steel bars 11 fit together and are inserted into the limiting box 21, thereby limiting the two steel bars 11 and allowing them to be in a vertical and close-fitting state.

[0034] The connecting plate 22 is fixed to the limiting box 21 by bolts. One side of the connecting plate 22 abuts against the outer wall of the reinforcing bar 11. Under the action of the connecting plate 22, the connection area between the connecting plate 22 and the reinforcing bar 11 can be increased, thereby improving the connection stability between the limiting box 21 and the reinforcing bar 11. At the same time, it can also reduce the possibility of the two reinforcing bars 11 sliding out or shifting from the placement groove. The number of fastening components 2 depends on the specific situation. In this embodiment, there are two fastening components 2, which are distributed at the top and bottom of the reinforcing bar 11, thereby limiting the two reinforcing bars 11. Then, the two reinforcing bars 11 are welded together, thereby further improving the connection stability between the two reinforcing bars 11. After the reinforcing bars 11 are limited by the fastening components 2, it is easier for construction personnel to weld the two reinforcing bars 11.

[0035] Reference Figure 1 The corner ribs 1 are set vertically, and there are four corner ribs 1. The four corner ribs 1 are distributed in a rectangular shape. The outer walls of the four corner ribs 1 are fitted with stirrups 3. Under the action of the stirrups 3, the four corner ribs 1 are connected. There are multiple stirrups 3. The multiple stirrups 3 are distributed along the vertical direction of the corner ribs 1. After the four corner ribs 1 and the stirrups 3 are assembled, a rectangular frame is formed. The cross-section of the rectangular frame includes the X-axis direction and the Y-axis direction. The length of the rectangular frame in the X-axis direction is greater than the length of the rectangular frame in the Y-axis direction.

[0036] The two inner walls of the stirrup 3 along the X-axis are respectively provided with a first longitudinal reinforcement group 4. The first longitudinal reinforcement group 4 is arranged vertically and there are multiple groups of first longitudinal reinforcement groups 4. The multiple groups of first longitudinal reinforcement groups 4 are distributed along the X-axis of the stirrup 3. The number of first longitudinal reinforcement groups 4 distributed on the two inner walls of the stirrup 3 is the same. The first longitudinal reinforcement groups 4 on the two inner walls of the stirrup 3 correspond to each other. The first longitudinal reinforcement group 4 includes two first longitudinal reinforcements 41. The structure of the first longitudinal reinforcement 41 is the same as the structure of the corner reinforcement 1. In this embodiment of the application, it will not be described in detail. The two first longitudinal reinforcements 41 are arranged relatively parallel.

[0037] The outer walls of the two corresponding sets of first longitudinal reinforcement groups 4 are respectively fitted with connecting bars 5. The connecting bars 5 connect the four first longitudinal reinforcements 41. The long side of the connecting bar 5 is parallel to the Y-axis direction. After the four first longitudinal reinforcements 41 and the connecting bars 5 are assembled, a small rectangular frame is formed inside the stirrups 3. Under the action of the connecting bars 5, the connecting bars 5 can limit the four first longitudinal reinforcements 41. The outer wall of the first longitudinal reinforcement 41 abuts against the inner wall of the connecting bars 5, so that the line connecting the two opposite first longitudinal reinforcements 41 is parallel to the Y-axis direction, thereby enhancing the overall stability and rigidity of the frame column. At the same time, during the concrete pouring process, it can reduce the displacement of the first longitudinal reinforcements 41 during the pouring process.

[0038] The long side of the cross-section of the first longitudinal reinforcement 41 is parallel to the long side of the connecting reinforcement 5, which makes the contact area between the outer wall of the first longitudinal reinforcement 41 and the long side of the connecting reinforcement 5 larger. This allows for better restraint of the four first longitudinal reinforcements 41. Compared with the case where the long side of the cross-section of the first longitudinal reinforcement is parallel to the wide side of the connecting reinforcement, this application can reduce the space occupied by the stirrups 3 in the X-axis direction, thus providing more space for the beam reinforcement 11 to pass through.

[0039] Reference Figure 1 The two inner walls of the stirrup 3 along the Y-axis are respectively provided with a second longitudinal reinforcement group 6. The second longitudinal reinforcement group 6 is arranged vertically and there are multiple groups of second longitudinal reinforcement groups 6. The multiple groups of second longitudinal reinforcement groups 6 are distributed along the Y-axis of the stirrup 3. The number of second longitudinal reinforcement groups 6 distributed on the two inner walls of the stirrup 3 is the same. The second longitudinal reinforcement groups 6 on the two inner walls of the stirrup 3 correspond to each other. The second longitudinal reinforcement group 6 includes two second longitudinal reinforcements 61. The structure of the second longitudinal reinforcement 61 is the same as the structure of the first longitudinal reinforcement 41. In this embodiment of the application, it will not be described in detail. The two second longitudinal reinforcements 61 are arranged relatively parallel.

[0040] The outer walls of the two corresponding sets of second longitudinal reinforcement groups 6 are respectively fitted with fixing reinforcement 7, and connecting reinforcement 5 connects the four second longitudinal reinforcements 61. The long side of the connecting reinforcement 5 is parallel to the X-axis direction. After the four second longitudinal reinforcements 61 are assembled with the fixing reinforcement 7, a small rectangular frame is formed in the stirrup 3. After the fixing reinforcement 7 is assembled with the connecting reinforcement 5, a grid structure is formed in the stirrup 3. Under the action of the fixing reinforcement 7, the four second longitudinal reinforcements 61 can be limited, which can enhance the overall stability and rigidity of the frame column and reduce the displacement of the second longitudinal reinforcements 61 during the pouring process.

[0041] The long sides of the cross-sections of the multiple second longitudinal bars 61 located on one side of the inner wall of the stirrup 3 along the Y-axis are parallel to the long side of the fixing bar 7, thus resulting in a larger contact area between the outer wall of the second longitudinal bars 61 and the long side of the fixing bar 7, which allows for better restraint of the four second longitudinal bars 61. The long sides of the cross-sections of the multiple second longitudinal bars 61 located on the other side of the inner wall of the stirrup 3 along the Y-axis are parallel to the wide side of the fixing bar 7, as shown in the reference. Figure 3 Compared to the case where the long sides of the cross-sections of multiple second longitudinal bars on both sides of the stirrups are parallel to the long sides of the fixed bars, this application can increase the space in the X-axis direction within the stirrup 3 frame.

[0042] The beam reinforcement 11 passes through the stirrup 3, and the long side of the beam reinforcement 11 is parallel to the Y-axis direction. The beam reinforcement 11 passes through the space between two adjacent first longitudinal reinforcements 41. This application correspondingly increases the space in the X-axis direction within the stirrup 3, thereby increasing the space for the beam reinforcement 11 to pass through, making it easier to install the beam reinforcement 11 between the two first longitudinal reinforcements 41, thereby accelerating the project progress and shortening the construction period.

[0043] The above are all preferred embodiments of this application. These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
