[0002] Reinforced concrete shear walls are commonly used lateral force resisting members in high-rise buildings, and their mechanical properties are crucial for the seismic performance of the overall structure. In concrete structures with transfer floors, it is often encountered that the shear resistance of the shear walls above the transfer floor is insufficient, and the thickness of the shear walls cannot be increased due to various reasons. It is necessary to add steel plates inside the shear walls. Since the longitudinal and transverse stirrups of the transfer beams are relatively dense, it is difficult to directly anchor the steel plates in the transfer beams during construction, and at the same time, the construction quality is also difficult to guarantee. Summary of the Invention
[0003] To solve the above technical problems, the present invention provides a corner structure of a steel plate shear wall and its construction method, which solves the technical problems of insufficient shear resistance of the shear walls above the transfer floor in concrete structures with transfer floors, the inability to increase the thickness of the shear walls due to various reasons, and the difficulty in anchoring the column feet of the steel plate shear walls.
[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:
[0005] A corner structure of a steel plate shear wall includes: transfer beam steel bars tied in a crisscross pattern. A fixed steel plate is arranged above the transfer beam steel bars. The fixed steel plate is fixedly installed above the transfer beam steel bars through stud bolts arranged below the fixed steel plate. The fixed steel plates are evenly distributed at equal intervals above the transfer beam steel bars. Shear wall steel bars are fixedly installed and tied through the fixed steel plates. When pouring concrete, the fixed steel plates are poured inside the shear wall steel bars.
[0006] Preferably, the transfer beam steel bars include transfer beam longitudinal steel bars and transfer beam transverse steel bars. The transfer beam longitudinal steel bars and the transfer beam transverse steel bars are fixedly tied in a crisscross pattern, and a stirrup spacing of 100 mm is reserved between two adjacent transfer beam longitudinal steel bars and transfer beam transverse steel bars.
[0007] Preferably, the stud bolts of the fixed steel plate are evenly distributed at the bottom of the fixed steel plate, and the axial spacing between two adjacent stud bolts coincides with the stirrup spacing of the transfer beam steel bars.
[0008] Preferably, the stud bolts of the fixed steel plate are inserted inside the transfer beam steel bars and are arranged below the beam surface of the transfer beam. When pouring concrete for the transfer beam steel bars, the stud bolts should be covered.
[0009] Preferably, mounting holes are provided on the fixing steel plate. The longitudinal shear wall reinforcement bars of the shear wall are arranged on both sides of the fixing steel plate. The binding bars of the shear wall reinforcement bars are inserted into the mounting holes of the fixing steel plate to bind the shear wall reinforcement bars, and the binding bars are used to ensure the positions of the longitudinal shear wall reinforcement bars.
[0010] Preferably, the mounting holes of the fixing steel plate are evenly distributed at equal intervals in the transverse and longitudinal directions. The diameter of the mounting holes matches the diameter of the binding bars of the shear wall reinforcement bars. The longitudinal shear wall reinforcement bars of the shear wall are arranged beside the mounting holes of the fixing steel plate.
[0011] Preferably, the thickness of the steel plate of the fixing steel plate, the depth of the stud, and the thickness of the transfer beam surface need to be calculated and determined according to the overall structure. The number of fixing steel plates can be added according to the size of the transfer beam surface.
[0012] A construction method for the corner structure of a steel plate shear wall includes the following steps:
[0013] Step 1: Calculate data;
[0014] Specifically: The staff calculates the height of the transfer beam reinforcement bars required, the thickness of the steel plate of the fixing steel plate, the depth of the stud, and the thickness of the transfer beam surface according to the required overall structure.
[0015] Step 1. Bind the transfer beam reinforcement bars;
[0016] Specifically: The staff should first clean up the garbage and the like on the cushion layer and inside the formwork. Before binding the transfer beam reinforcement bars, draw the position lines of the transfer beam reinforcement bars on the formwork: The bottom slab reinforcement bars should be marked on the cushion layer; the wall reinforcement bars should be marked on the formwork; the column stirrups should be marked at points on two diagonals, and the stirrups of the beam should be marked at points on the erection bars. The stirrup spacing between the longitudinal and transverse reinforcement bars of the bound transfer beam is set to 100 mm.
[0017] Step 2. Install the fixing steel plate inside the shear wall longitudinal reinforcement;
[0018] Specifically: The staff welds the studs at equal intervals at the bottom of the fixing steel plate. The axial spacing of the studs is set to 100 mm, which is the same as the stirrup spacing of the transfer beam reinforcement bars. After welding, equally spaced mounting holes are opened on the fixing steel plate as needed. The size of the mounting holes matches the binding bars. The staff inserts multiple fixing steel plates above the transfer beam reinforcement bars to ensure that the studs are inserted into the stirrup spacing of the transfer beam reinforcement bars and the studs are arranged below the transfer beam surface.
[0019] Step 3. Install the shear wall longitudinal reinforcement;
[0020] Specifically: The staff installs the longitudinal shear wall steel bars, and the longitudinal shear wall steel bars are fixedly installed on both sides of the fixed steel plate and the positions of the longitudinal shear wall steel bars are close to the positions of the mounting holes of the fixed steel plate;
[0021] Step Four: Pour the concrete of the transfer beam;
[0022] Specifically: The staff pours the concrete for the transfer beam steel bars to ensure that the concrete covers the stud bolts under the fixed steel plate;
[0023] Step Five: Bind the steel bars;
[0024] Specifically: The staff passes the binding steel bars through the mounting holes of the fixed steel plate to bind the longitudinal shear wall steel bars, ensuring that each longitudinal shear wall steel bar and the adjacent two longitudinal shear wall steel bars are fixed by different binding steel bars;
[0025] Step Six: Pour the concrete of the shear wall;
[0026] Specifically: The staff pours the shear wall to make the concrete cover the fixed steel plate and the shear wall steel bars to form the required integral structure of the shear wall.
[0027] Preferably, for the welding of the stud bolts at the bottom of the fixed steel plate described in Step Two, a drawn arc stud welding machine and a welding torch are used, and a deoxidized arc heat-resistant ceramic seat ring is used. The stud bolts shall ensure that there are no cracks in the rod part that affect the use.
[0028] Preferably, for the parts and installation operations required in Steps Two to Six, the dimensional errors of the height of the transfer beam steel bars, the steel plate thickness of the fixed steel plate, the depth of the stud bolts, and the thickness of the transfer beam surface calculated by the staff according to the required integral structure shall not exceed.
[0029] The beneficial effects of the present invention compared with the prior art are:
[0030] 1. In the present invention, due to the existence of the transfer beam steel bars, the fixed steel plate and the shear wall steel bars, the construction operation of the integral structure is simple and the construction quality is reliable. The stud bolts of the fixed steel plate are included in the concrete to fix the fixed steel plate, which can greatly enhance the connection strength between the fixed steel plate and the concrete.
[0031] 2. In the present invention, there is a 100 mm stirrup spacing reserved between the longitudinal transfer beam steel bars and the transverse transfer beam steel bars, which facilitates the installation of the fixed steel plate, so that the fixed steel plate can be directly anchored on the transfer beam, and the number of fixed steel plates on the transfer beam can also be increased or decreased according to the required structure, and the operation is convenient and fast.
[0032] 3. In the present invention, stud bolts are arranged at equal intervals under the fixed steel plate, and the interval of the stud bolts coincides with the stirrup interval of the reinforcement bars of the transfer beam, so that the fixed steel plate can be smoothly inserted into the beam surface of the transfer beam for direct anchoring, thereby solving the problem that the steel plate in the existing structure cannot be directly anchored on the transfer beam.
[0033] 4. Since the stud bolts of the fixed steel plate are included in the concrete in the present invention, the connection strength between the fixed steel plate and the concrete can be greatly enhanced, the overall mechanical properties of the shear wall reinforcement bars fixedly installed on the fixed steel plate can be improved, and the shear resistance of the shear wall can be enhanced.
[0034] 5. In the present invention, the longitudinal reinforcement bars of the shear wall are tied by tying the reinforcement bars through the installation holes of the fixed steel plate. The diameter of the installation holes coincides with the diameter of the tying reinforcement bars of the shear wall reinforcement bars, which can effectively ensure that the installation holes pass through the fixed steel plate, and ensure the fixed installation of the fixed steel plate and the shear wall reinforcement bars, thereby ensuring the stable connection between the shear wall and the transfer beam.

[0049] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.
[0050] In order to solve the technical problems of insufficient shear resistance of the shear wall above the transfer story in the concrete structure with a transfer story, the thickness of the shear wall cannot be thickened due to various reasons, and it is difficult to anchor the column foot of the steel plate shear wall, as Figures 1 to 4 shown, the following technical solutions are provided:
[0051] A steel plate shear wall corner structure includes: transfer beam reinforcement 1 tied in a crisscross pattern. Above the transfer beam reinforcement 1, there is a fixed steel plate 2. The fixed steel plate 2 is fixedly installed above the transfer beam reinforcement 1 through studs 2a provided below the fixed steel plate 2. The fixed steel plates 2 are evenly distributed at equal intervals above the transfer beam reinforcement 1. The shear wall reinforcement 3 is fixedly installed and tied with reinforcement through the fixed steel plate 2. When pouring concrete, the fixed steel plate 2 is poured inside the shear wall reinforcement 3.
[0052] Specifically, the shear wall reinforcement 3 with studs 2a is fixedly installed on the transfer beam reinforcement 1 so that the studs 2a can play a role in rigid combination connection between the transfer beam reinforcement 1 and the shear wall reinforcement 3. After pouring concrete for the transfer beam reinforcement 1, the studs 2a of the fixed steel plate 2 are contained in the concrete to fix the fixed steel plate 2, which can greatly strengthen the connection strength between the fixed steel plate 2 and the concrete, improve the overall mechanical properties of the shear wall reinforcement 3 fixedly installed on the fixed steel plate 2, enhance the shear resistance of the shear wall, and the number of the fixed steel plates 2 on the transfer beam reinforcement 1 can be added as needed, which is convenient for the staff to increase the thickness of the shear wall. Due to the existence of the transfer beam reinforcement 1, the fixed steel plate 2 and the shear wall reinforcement 3, the overall structure construction operation is simple and the construction quality is reliable.
[0053] Furthermore:
[0054] In order to solve the technical problems that the longitudinal and transverse stirrups of the transfer beam are relatively dense, it is difficult to directly anchor the steel plate in the transfer beam during construction, and at the same time, it is difficult to guarantee the construction quality, as Figures 5 to 7 shown, the following technical solutions are provided: The transfer beam reinforcement 1 includes transfer beam longitudinal reinforcement 1a and transfer beam transverse reinforcement 1b. The transfer beam longitudinal reinforcement 1a and the transfer beam transverse reinforcement 1b are fixedly tied in a crisscross pattern, and there is a stirrup spacing of 100 mm reserved between two adjacent transfer beam longitudinal reinforcement 1a and transfer beam transverse reinforcement 1b.
[0055] Specifically, since the longitudinal and stirrup bars of the transfer beam are relatively dense, when the staff binds the steel bars 1 of the transfer beam, a stirrup spacing of 100 mm should be reserved between the adjacent longitudinal steel bars 1a and transverse steel bars 1b of the transfer beam to facilitate the installation of the fixing steel plate 2, so that the fixing steel plate 2 can be directly anchored on the transfer beam 2. The number of the fixing steel plates 2 on the transfer beam can also be increased or decreased according to the required structure, and the operation is convenient and fast.
[0056] Furthermore:
[0057] To solve the technical problem of the difficult construction of directly anchoring the steel plate in the transfer beam, as Figure 5 , Figure 6 and Figure 8 shown, the following technical solution is provided: the stud bolts 2a of the fixing steel plate 2 are evenly distributed at the bottom of the fixing steel plate 2, and the axial spacing between two adjacent stud bolts 2a coincides with the stirrup spacing of the transfer beam steel bars 1.
[0058] Specifically, the staff evenly arranges the stud bolts 2a under the fixing steel plate 2. The stud bolts 2a are welded to the bottom of the fixing steel plate 2. The spacing of the stud bolts 2a coinciding with the stirrup spacing of the transfer beam steel bars 1 can enable the fixing steel plate 2 to be smoothly inserted into the transfer beam surface for direct anchoring, thus solving the problem that the steel plate cannot be directly anchored on the transfer beam in the existing structure.
[0059] Furthermore:
[0060] To solve the technical problem of how the stud bolts 2a enhance the shear resistance of the shear wall, as Figure 5 and 6 shown, the following technical solution is provided: the stud bolts 2a of the fixing steel plate 2 are inserted inside the transfer beam steel bars 1 and arranged below the transfer beam surface. When pouring concrete for the transfer beam steel bars 1, the stud bolts 2a should be covered.
[0061] Specifically, when pouring concrete for the transfer beam, the stud bolts 2a of the fixing steel plate 2 being included in the concrete can fix the fixing steel plate 2 and can also greatly strengthen the connection strength between the fixing steel plate 2 and the concrete, improve the overall mechanical properties of the shear wall steel bars 3 fixedly installed on the fixing steel plate 2, and enhance the shear resistance of the shear wall.
[0062] Furthermore:
[0063] To solve the technical problem of how to fixedly connect the shear wall steel bars 3 with the fixing steel plate 2, as Figure 8 and 9As shown in the figure, the following technical solutions are provided: The fixing steel plate 2 is provided with mounting holes 2b. The longitudinal shear wall steel bars 3a of the shear wall steel bars 3 are arranged on both sides of the fixing steel plate 2. The binding steel bars 3b of the shear wall steel bars 3 are inserted into the mounting holes 2b of the fixing steel plate 2 to bind the shear wall steel bars 3, and the binding steel bars 3b are used to ensure the position of the longitudinal shear wall steel bars 3a.
[0064] Specifically, by binding the longitudinal shear wall steel bars 3a through the mounting holes 2b provided on the fixing steel plate 2 in cooperation with the binding steel bars 3b of the shear wall steel bars 3, the longitudinal shear wall steel bars 3a can be effectively fixedly connected to the fixing steel plate 2, so that the fixing steel plate 2 can effectively enhance the mechanical properties of the shear wall and improve the stability of the shear wall steel bars 3.
[0065] Furthermore:
[0066] To solve the technical problem of how to ensure the binding effect of the binding steel bars 3b on the longitudinal shear wall steel bars 3a, as Figure 9 and 10 shown in the figure, the following technical solutions are provided: The mounting holes 2b of the fixing steel plate 2 are evenly distributed at equal intervals in the transverse and longitudinal directions. The diameter of the mounting holes 2b is consistent with the diameter of the binding steel bars 3b of the shear wall steel bars 3. The longitudinal shear wall steel bars 3a of the shear wall steel bars 3 are arranged beside the mounting holes 2b of the fixing steel plate 2.
[0067] Specifically, by passing the binding steel bars 3b through the mounting holes 2b of the fixing steel plate 2 to bind the longitudinal shear wall steel bars 3a, the diameter of the mounting holes 2b being consistent with the diameter of the binding steel bars 3b of the shear wall steel bars 3 can effectively ensure that the mounting holes 2b pass through the fixing steel plate 2. By arranging the longitudinal shear wall steel bars 3a of the shear wall steel bars 3 beside the mounting holes 2b of the fixing steel plate 2, it can be ensured that after the binding steel bars 3b pass through the mounting holes 2b, they can effectively bind the longitudinal shear wall steel bars 3a, enhancing the stability between the longitudinal shear wall steel bars 3a and the fixing steel plate 2, thereby improving the shear resistance of the shear wall.
[0068] Furthermore:
[0069] To solve the technical problem of how to ensure the shear resistance of the corner structure, as Figures 1 to 4 shown in the figure, the following technical solutions are provided: The thickness of the steel plate 2 of the fixing steel plate, the depth of the stud 2a, and the thickness of the transfer beam surface all need to be calculated and determined according to the overall structure. The number of fixing steel plates 2 can be added according to the size of the transfer beam surface.
[0070] Specifically, the staff determines the specific dimensions of each component based on the data of the required structure. Through precise calculations, it can be ensured that different structures can have the maximum shear resistance in different environments. At the same time, it is also convenient for the staff to carry out construction and installation, simplify the operation, and avoid affecting the construction progress due to component size problems.
[0071] A construction method for the corner structure of a steel plate shear wall, and the specific steps of this construction method are as follows:
[0072] Step 1: Calculate data;
[0073] Specifically: The staff calculates the height of the transfer beam reinforcement 1 required according to the required overall structure, the steel plate thickness of the fixed steel plate 2, the depth of the stud 2a, and the thickness of the transfer beam surface;
[0074] Step 1: Bind the transfer beam reinforcement 1;
[0075] Specifically: The staff should first clean up the garbage on the cushion and inside the formwork. Before binding the transfer beam reinforcement 1, draw the position line of the transfer beam reinforcement 1 on the formwork: The bottom plate reinforcement should be marked on the cushion; the wall reinforcement should be marked on the formwork; the column stirrups should be marked at points on two diagonal lines, and the beam stirrups should be marked at points on the erection bars. The stirrup spacing of the longitudinal reinforcement 1a and the transverse reinforcement 1b of the bound transfer beam is set to 100 mm;
[0076] Step 2: Install and fix the fixed steel plate 2 inside the shear wall reinforcement 3;
[0077] Specifically: The staff welds the studs 2a at equal intervals at the bottom of the fixed steel plate 2. The axial spacing of the studs 2a is set to 100 mm, which is the same as the stirrup spacing of the transfer beam reinforcement 1. After welding, equally spaced installation holes 2b are opened on the fixed steel plate 2 as required. The size of the installation holes 2b matches the bound reinforcement 3b. The staff inserts multiple fixed steel plates 2 above the transfer beam reinforcement 1, ensuring that the studs 2a are inserted into the stirrup spacing of the transfer beam reinforcement 1 and the studs 2a are arranged below the transfer beam surface;
[0078] Step 3: Install the longitudinal shear wall reinforcement 3a;
[0079] Specifically: The staff installs the longitudinal shear wall reinforcement 3a. The longitudinal shear wall reinforcement 3a is fixedly installed on both sides of the fixed steel plate 2 and the position of the longitudinal shear wall reinforcement 3a is close to the position of the installation holes 2b of the fixed steel plate 2;
[0080] Step 4: Pour the transfer beam concrete;
[0081] Specifically: The staff pours the concrete for the transfer beam reinforcement 1, ensuring that the concrete covers the studs 2a below the fixed steel plate 2;
[0082] Step Five: Binding. Bind the steel bars 3b.
[0083] Specifically: The worker passes the binding steel bars 3b through the installation holes 2b of the fixed steel plate 2 to bind the longitudinal shear wall steel bars 3a, ensuring that each longitudinal shear wall steel bar 3a and the adjacent two longitudinal shear wall steel bars 3a are fixed by different binding steel bars 3b.
[0084] Step Six: Pour the shear wall concrete.
[0085] Specifically: The worker pours the shear wall, so that the concrete covers the fixed steel plate 2 and the shear wall steel bars 3, forming the required integral structure of the shear wall.
[0086] Furthermore:
[0087] To solve the technical problem of how to ensure that the stud 2a is fixedly installed on the fixed steel plate 2 and ensure its connection strength, as Figure 8 shown, the following technical solution is provided: The stud 2a at the bottom of the fixed steel plate 2 described in Step Two is welded using an arc stud welding machine and a welding torch, and a deoxidizing arc heat-resistant ceramic collar is used. The stud 2a must ensure that there are no cracks in the rod part that affect its use.
[0088] Specifically, according to the national standard regulations, the surface of the stud should be free of rust, oxide scale, grease, burrs, etc. There are no cracks in the rod part of the stud that are allowed to affect its use, but the depth of the cracks in the head shall not exceed 0.25dk - dmm radially. The arc stud welding machine and the welding torch can effectively weld the stud 2a to the lower bottom surface of the fixed steel plate 2. The fact that there are no cracks in the rod part of the stud 2a can ensure the connection stability and stress strength of the stud 2a.
[0089] Furthermore:
[0090] To solve the technical problem of how to ensure that the integral structure reaches the ideal data, as Figures 1 to 10 shown, the following technical solution is provided: The dimensions of the components and installation operations required in Steps Two to Six shall not exceed 1 mm in error from the height of the transfer beam steel bars 1 calculated by the worker according to the required integral structure in Step One, the steel plate thickness of the fixed steel plate 2, the depth of the stud 2a, and the thickness of the transfer beam surface.
[0091] Specifically, the actual manufactured components and the specific installation operations shall ensure that the error from the data calculated by the worker according to the required integral structure in Step One is less than 1 mm, which can ensure the smooth anchoring of the fixed steel plate 2 and the transfer beam steel bars 1 and the stability of the shear wall steel bars 3 fixed on the fixed steel plate 2, thus ensuring that the wall reaches the ideal shear resistance.
[0092] The working principle of the present invention:
[0093] It is fixedly installed on the transfer beam steel bars 1 through the shear wall steel bars 3 with stud bolts 2a, so that the stud bolts 2a can play a role of rigid combined connection between the transfer beam steel bars 1 and the shear wall steel bars 3. After the transfer beam steel bars 1 are poured with concrete, the stud bolts 2a of the fixing steel plate 2 are contained in the concrete to fix the fixing steel plate 2, which can greatly enhance the connection strength between the fixing steel plate 2 and the concrete, improve the overall mechanical properties of the shear wall steel bars 3 fixedly installed on the fixing steel plate 2, enhance the shear resistance of the shear wall, and the number of the fixing steel plates 2 on the transfer beam steel bars 1 can be added as needed, which is convenient for the staff to increase the thickness of the shear wall. Due to the existence of the transfer beam steel bars 1, the fixing steel plate 2 and the shear wall steel bars 3, the overall structure construction operation is simple and the construction quality is reliable.
