[0029] Because the buildings in older residential areas use frame structures, the frames bear all the vertical and horizontal loads, and the infill walls do not participate in the work as part of the structure, resulting in low seismic performance that cannot meet current seismic standards.
[0030] Therefore, it is necessary to reinforce the buildings in old residential areas to improve their earthquake resistance.
[0031] This utility model proposes a concrete-surfaced shear wall structure 100. Please refer to [link / reference]. Figure 1 In one embodiment of this utility model, the concrete surface layer anti-shear wall structure 100 proposed by this utility model includes:
[0032] Original infill wall 10;
[0033] The original beam 20 is connected to the original infill wall 10;
[0034] A shear wall structure 30 includes rebar 31, steel reinforcement assemblies 32, and a concrete wall structure 35. The concrete wall structure 35 includes a first wall structure 351 and a second wall structure 352. The first wall structure 351 is connected to one side of the original beam 20, and the second wall structure 352 extends along the length of the original infill wall 10 and is connected to both the original infill wall 10 and the first wall structure 351. A portion of the rebar 31 is located in the original beam 20, and another portion is located in either the first wall structure 351 or the second wall structure 352. A portion of the steel reinforcement assemblies 32 is located in the first wall structure 351, and another portion is located in the second wall structure 352.
[0035] Steel plate assembly 40, which is connected to the outside of the second wall structure 352.
[0036] The technical solution of this utility model involves adding a shear wall structure 30 with steel reinforcement components 32 to one side of the original infill wall 10 and the original beam 20, thereby reinforcing and modifying both sides of the original infill wall 10 to form a concrete-surfaced shear wall structure 100. This improves the stiffness and seismic bearing capacity of the original infill wall 10, thus enhancing its seismic performance. Furthermore, steel plate components 40 are installed on the exterior of the second wall structure 352, further increasing its strength and stiffness and improving its seismic resistance.
[0037] In one embodiment, shear wall structures 30 are symmetrically arranged on both sides of the original infill wall 10 and the original beam 20.
[0038] In one embodiment, the first wall structure 351 and the second wall structure 352 are provided with steel reinforcement components 32, thereby giving the concrete wall structure 35 strong seismic toughness and effectively improving the seismic performance of the shear wall structure 30.
[0039] This invention, without altering the structure of the original infill wall 10 and the original beam 20, makes full use of the original infill wall 10 and strengthens it by adding shear wall structures 30 on both sides of the original infill wall 10, forming a high-toughness concrete surface layer shear wall structure 100. This improves the lateral stiffness of the original infill wall 10, thereby reducing the lateral displacement of the original infill wall 10 under earthquake action and strengthening the stiffness and shear bearing capacity of the original infill wall 10.
[0040] Furthermore, shear wall structures 30 are added on both sides of the original infill wall 10. The shear wall structures 30 bear most of the seismic force, reducing the stress on the original beam 20.
[0041] The shear wall structure 30 uses rebar 31 anchored into the original beam 20. The rebar 31 is anchored to the original beam 20 to ensure that the horizontal shear force is effectively transferred to the shear wall structure 30.
[0042] In one embodiment, the reinforcing steel assembly 32 includes a fixed reinforcing steel cage 33 and a fixed reinforcing steel mesh assembly 34. The fixed reinforcing steel cage 33 is disposed on the first wall structure 351, and the fixed reinforcing steel mesh assembly 34 is disposed on the second wall structure 352. The fixed reinforcing steel cage 33 is connected to the fixed reinforcing steel mesh assembly 34.
[0043] Specifically, the fixed reinforcing cage 33 includes a first vertical bar 331, a second vertical bar 332, a third vertical bar 333, a short horizontal bar 334, a first long horizontal bar 335, and a second long horizontal bar 336. The first long horizontal bar 335 and the second long horizontal bar 336 are spaced apart, and the short horizontal bar 334 connects the first long horizontal bar 335 and the second long horizontal bar 336. A plurality of first vertical bars 331 are arranged along the length direction of the first long horizontal bar 335, a plurality of second vertical bars 332 are arranged along the length direction of the second long horizontal bar 336, and a plurality of third vertical bars 333 are arranged along the length direction of the short horizontal bar 334. The first long horizontal bar 335 is connected to the first vertical bar 331 by a binding member, the second long horizontal bar 336 is connected to the second vertical bar 332 by a binding member, and the short horizontal bar 334 is connected to the third vertical bar 333 by a binding member.
[0044] The structure comprises multiple first long horizontal reinforcing bars 335 and multiple second long horizontal reinforcing bars 336. The first long horizontal reinforcing bars 335 are arranged vertically along the length of the first vertical reinforcing bars 331, and the second long horizontal reinforcing bars 336 are arranged vertically along the length of the second vertical reinforcing bars 332. The first vertical reinforcing bars 331 and the first long horizontal reinforcing bars 335 are connected by binding members, and the second vertical reinforcing bars 332 and the second long horizontal reinforcing bars 336 are also connected by binding members. Each first long horizontal reinforcing bar 335 is connected to each second long horizontal reinforcing bar 336 by a short horizontal reinforcing bar 334, thus forming the fixed reinforcing cage 33. The fixed reinforcing cage 33 within the first wall structure 351 enhances the toughness and seismic performance of the first wall structure 351.
[0045] Optionally, some of the rebar 31 structures are connected to the first long horizontal bar 335 via a binding member.
[0046] To reduce the occurrence of skewness in the first vertical reinforcement 331 and the second vertical reinforcement 332, the fixed steel cage 33 further includes an S-shaped clamp 337. One end of the S-shaped clamp 337 is connected to the first vertical reinforcement 331, and the other end of the S-shaped clamp 337 is connected to the second vertical reinforcement 332, so as to limit the first vertical reinforcement 331 and the second vertical reinforcement 332 and ensure that both the first vertical reinforcement 331 and the second vertical reinforcement 332 can extend along the height direction of the original beam 20.
[0047] Specifically, the S-shaped clamp 337 includes a first hook 3371, a second hook 3372, and a connecting rod 3373. The first hook 3371 and the second hook 3372 are respectively located at both ends of the connecting rod 3373, and the first hook 3371 and the second hook 3372 are arranged opposite to each other. The first vertical rib 331 is engaged with the first hook 3371, and the second vertical rib 332 is engaged with the second hook 3372. There are multiple S-shaped clamps 337. The multiple S-shaped clamps 337 limit the first vertical rib 331 and the second vertical rib 332 through the first hook 3371 and the second hook 3372, ensuring that the first vertical rib 331 and the second vertical rib 332 can both extend along the height direction of the original beam 20.
[0048] In one embodiment, the fixed rib mesh assembly 34 includes a third long horizontal rib 341 and a plurality of fourth vertical ribs 342. The second long horizontal rib 336 extends along the length direction of the original infill wall 10, and one end of the third long horizontal rib 341 is connected to the first long horizontal rib 335. The plurality of fourth vertical ribs 342 are arranged along the length direction of the third long horizontal rib 341, and the plurality of fourth vertical ribs 342 are connected to the third long horizontal rib 341.
[0049] In one embodiment, the thickness of the first wall structure 351 is greater than the thickness of the second wall structure 352. A fixed reinforcing cage 33 is provided within the first wall structure 351 to enhance its toughness and seismic resistance due to its greater thickness. The second wall structure 352 is thinner and is provided with a fixed reinforcing mesh assembly 34 to ensure that the thinner second wall structure 352 also possesses high toughness and seismic resistance.
[0050] Please see Figure 2 The steel plate assembly 40 includes multiple horizontal plates 41 and two vertical plates 42. The multiple horizontal plates 41 are connected to the two vertical plates 42, and the multiple horizontal plates 41 are spaced apart vertically. Specifically, the two vertical plates 42 are welded to the multiple horizontal plates 41.
[0051] The second wall structure 352 is externally fitted with a steel plate assembly 40, which enhances the strength and rigidity of the second wall structure 352 and improves its seismic resistance.
[0052] First, the reinforcing bars 31 are inserted into the original beam 20, and then the fixed reinforcing cage 33 and the fixed reinforcing mesh assembly 34 are assembled. After that, a casting template is made. Then, concrete is poured into the fixed reinforcing cage 33 and the fixed reinforcing mesh assembly 34 to form a shear wall structure 30. Finally, the template is removed from the formed shear wall structure 30, and the steel plate assembly 40 is tightly attached to the surface of the second wall structure 352 by high-strength bolts or welding.
[0053] The shear wall structure 30 is connected to the original beam 20 and the original infill wall 10 to form the concrete surface layer shear wall structure 100.
[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
