This makes the brick walls prone to cracking due to uneven settlement or external forces, and the brick walls have poor seismic resistance. Utility Model Content
[0004] The main purpose of this utility model is to propose a seismically reinforced concrete wall structure, which aims to solve the problem of poor seismic performance of existing buildings.
[0005] To achieve the above objectives, the present invention proposes a seismically reinforced concrete wall structure, comprising:
[0006] The beam body includes an upper beam structure and a lower beam structure;
[0007] The original column, fixed to the lower beam structure, includes a fixed column and a first reinforcing steel structure, the first reinforcing steel structure being located inside the fixed column; and
[0008] A reinforced concrete wall includes a second steel reinforcement structure and a wall body, wherein the wall body is located between an upper beam structure and a lower beam structure, and the second steel reinforcement structure is located inside the wall body.
[0009] The second steel reinforcement structure includes multiple horizontal steel bars and multiple vertical steel bars. Parts of the multiple horizontal steel bars are anchored inside the fixed column, and other parts of the multiple horizontal steel bars are located in the wall body. Parts of the multiple vertical steel bars are anchored to the lower beam structure to be fixed to the lower beam structure, and other parts of the multiple vertical steel bars are located in the wall body. The multiple vertical steel bars and the multiple horizontal steel bars are fixed perpendicularly to each other to form a frame structure.
[0010] The first reinforcing bar is partially located on the wall body and is parallel to the horizontal reinforcing bar; the second reinforcing bar structure also includes an S-shaped clamp, which is used to connect two vertical reinforcing bars that are spaced apart in the width direction of the upper beam structure.
[0011] In some embodiments, each of the transverse reinforcing bars includes a anchor bar and a positioning bar, the anchor bar being anchored to the fixed column for fixation, and the positioning bar extending along the length of the upper beam structure and disposed within the wall body.
[0012] In some embodiments, the plurality of vertical reinforcing bars includes a plurality of first vertical reinforcing bars and a plurality of second vertical reinforcing bars, the plurality of first vertical reinforcing bars and the plurality of second vertical reinforcing bars being arranged along the length direction of the upper beam structure, and the first vertical reinforcing bars and the second vertical reinforcing bars having a spacing in the width direction of the upper beam structure.
[0013] In some embodiments, the horizontal reinforcing bars include a first horizontal reinforcing bar and a second horizontal reinforcing bar, the first horizontal reinforcing bar and the second horizontal reinforcing bar being spaced apart in the width direction of the upper beam structure, the first horizontal reinforcing bar being perpendicular to the first vertical reinforcing bar, the first horizontal reinforcing bar being tied to the first vertical reinforcing bar by steel wire, the second horizontal reinforcing bar being perpendicular to the second vertical reinforcing bar, and the second horizontal reinforcing bar being tied to the second vertical reinforcing bar by steel wire.
[0014] In some embodiments, the second reinforcing steel structure further includes a limiting member that binds and fixes the two first vertical reinforcing bars and the two second vertical reinforcing bars to limit their movement.
[0015] In some embodiments, the limiting member and the S-shaped card are spaced apart.

[0018] In some embodiments, the steel plate is a strip steel plate.
[0019] The technical solution of this utility model replaces the original brick wall structure with a reinforced concrete wall. In the second reinforcing steel structure of the reinforced concrete wall, a portion of the horizontal reinforcing bars is anchored inside a fixed column, while another portion of the horizontal reinforcing bars is located within the wall body. A portion of the vertical reinforcing bars is anchored to the upper beam structure for fixation, while another portion of the vertical reinforcing bars is located within the wall body. The vertical and horizontal reinforcing bars are fixed perpendicularly to each other. A portion of the first reinforcing bar is located within the wall body and parallel to the horizontal reinforcing bars. The second reinforcing steel structure also includes S-shaped clips for connecting two vertical reinforcing bars spaced apart in the width direction of the upper beam structure, thereby improving the stability of the second reinforcing steel structure. This invention anchors a portion of the horizontal reinforcing bars in the second steel reinforcement structure of the reinforced concrete wall inside the fixed column, while another portion of the horizontal reinforcing bars is located in the wall body.

[0032] Currently, existing building design codes and requirements are gradually being raised, which means that existing buildings can no longer meet current seismic standards. Therefore, it is necessary to reinforce existing buildings to improve their seismic resistance.
[0033] The existing brick walls have low stiffness and shear capacity, and the original brick walls are not effectively anchored to the columns, resulting in weak overall integrity. This makes the brick walls prone to cracking due to uneven settlement or external forces, and the brick walls have poor seismic resistance.
[0034] This utility model proposes a seismically reinforced concrete wall structure 100. Please refer to [link / reference]. Figures 1 to 3 In one embodiment of this utility model, the seismic-resistant reinforced concrete wall structure 100 proposed by this utility model includes:
[0035] The beam body 10 includes an upper beam structure 11 and a lower beam structure 12;
[0036] Original column 20, fixed to the lower beam structure 12, the original column 20 includes a fixed column 21 and a first reinforcing steel structure 22, the first reinforcing steel structure 22 being located inside the fixed column 21; and
[0037] A reinforced concrete wall 30 includes a second steel reinforcement structure 32 and a wall body 31. The wall body 31 is located between the upper beam structure 11 and the lower beam structure 12, and the second steel reinforcement structure 32 is located inside the wall body 31.
[0038] The second reinforcing steel structure 32 includes multiple horizontal reinforcing bars 33 and multiple vertical reinforcing bars 34. Part of the structure of the multiple horizontal reinforcing bars 33 is anchored inside the fixed column 21, and another part of the structure of the multiple horizontal reinforcing bars 33 is disposed in the wall body 31. Part of the structure of the multiple vertical reinforcing bars 34 is anchored to the lower beam structure 12 to be fixed with the lower beam structure 12, and another part of the structure of the multiple vertical reinforcing bars 34 is disposed in the wall body 31. The multiple vertical reinforcing bars 34 and the multiple horizontal reinforcing bars 33 are fixed perpendicularly to each other to form a frame structure.
[0039] The first reinforcing bar is partially located on the wall body 31 and is parallel to the horizontal reinforcing bar 33; the second reinforcing bar structure 32 also includes an S-shaped clip 35, which is used to connect two vertical reinforcing bars 34 that are spaced apart in the width direction of the upper beam structure 11.
[0040] This invention anchors a portion of the horizontal reinforcing bars 33 in the second reinforcing steel structure 32 of the reinforced concrete wall 30 to the interior of the fixed column 21, while another portion of the horizontal reinforcing bars 33 is located in the wall body 31. This ensures the effective transmission of horizontal shear force in the reinforced concrete wall 30. By effectively anchoring the horizontal reinforcing bars 33 to the original column 20, the reinforced concrete wall 30, the original column 20, and the beam 10 work together to distribute the load effectively, avoid stress concentration, and improve the seismic resistance of the reinforced concrete wall 30 compared to the original brick wall, thereby enhancing the seismic resistance of the building.
[0041] The multiple horizontal steel bars 33 in the second steel reinforcement structure 32 are fixed to the original column 20, and the multiple vertical steel bars 34 are fixed to the multiple horizontal steel bars 33. Then, a formwork can be installed so that concrete can be poured later to form the reinforced concrete wall 30.
[0042] Furthermore, each of the horizontal reinforcing bars 33 includes a anchor bar 333 and a positioning bar 334. The anchor bar 333 is anchored to the fixed column 21 for fixation. The positioning bar 334 extends along the length of the upper beam structure 11 and is located within the wall body 31. With this arrangement, the horizontal shear force of the reinforced concrete wall 30 is effectively transferred to the original column 20.
[0043] In one embodiment, the plurality of vertical reinforcing bars 34 include a plurality of first vertical reinforcing bars 341 and a plurality of second vertical reinforcing bars 342, the plurality of first vertical reinforcing bars 341 and the plurality of second vertical reinforcing bars 342 being arranged along the length direction of the upper beam structure 11, and the first vertical reinforcing bars 341 and the second vertical reinforcing bars 342 having a spacing in the width direction of the upper beam structure 11.
[0044] Please see Figure 2 and Figure 4 The horizontal reinforcing bars 33 include a first horizontal reinforcing bar 331 and a second horizontal reinforcing bar 332. The first horizontal reinforcing bar 331 and the second horizontal reinforcing bar 332 are spaced apart in the width direction of the upper beam structure 11. The first horizontal reinforcing bar 331 is perpendicular to the first vertical reinforcing bar 341. The first horizontal reinforcing bar 331 is tied to the first vertical reinforcing bar 341 with steel wire. The second horizontal reinforcing bar 332 is perpendicular to the second vertical reinforcing bar 342. The second horizontal reinforcing bar 332 is tied to the second vertical reinforcing bar 342 with steel wire.
[0045] Specifically, the reinforced concrete wall 30 includes two rows of vertical steel bars 34 and two rows of horizontal steel bars 33. The two rows of vertical steel bars 34 are fixed below the upper beam 10, and each row of vertical steel bars 34 is arranged along the length of the upper beam structure 11. The two rows of horizontal steel bars 33 are fixed to the original column 20, and there is a gap between the two rows of horizontal steel bars 33.
[0046] Each horizontal reinforcing bar 33 is tied and fixed to multiple vertical reinforcing bars 34 with steel wire.
[0047] To reduce the possibility of the vertical reinforcing bars 34 becoming skewed, the second reinforcing bar structure 32 also includes a limiting member 36, which binds and fixes the two first vertical reinforcing bars 341 and the two second vertical reinforcing bars 342 to limit their movement.
[0048] In one embodiment, the limiting member 36 and the S-shaped card member 35 are spaced apart.
[0049] Please see Figure 2 and Figure 4 The S-shaped clip 35 includes a first hook 351, a second hook 352, and a connecting rod 353. The first hook 351 and the second hook 352 are respectively disposed at both ends of the connecting rod 353, and the first hook 351 and the second hook 352 are arranged opposite to each other. The first vertical steel bar 341 is locked in the first hook 351, and the second vertical steel bar 342 is locked in the second hook 352, reducing the possibility of the first vertical steel bar 341 and the second vertical steel bar 342 being misaligned.
[0050] Please see Figure 2 and Figure 4 The second reinforcing steel structure 32 also includes a steel plate 37, which is tied and fixed to the adjacent vertical reinforcing steel bar 34 by steel wire, and the steel plate 37 is arranged parallel to the vertical reinforcing steel bar 34.
[0051] The steel plate 37 is integrally formed with the concrete wall body 31. This utility model utilizes the good tensile strength of the steel plate 37 to enhance the load-bearing capacity and rigidity of the reinforced concrete wall 30.
[0052] In one embodiment, the steel plate 37 is a strip steel plate 37, and the number of steel plates 37 is four. The above description is merely an exemplary embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of this utility model's specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
