[0041] The following is combined with Figure 1-13 This application is described in further detail.

[0042] Example 1 The present application embodiment discloses a shear wall structure and a construction method thereof. Figure 1 The shear wall structure includes a concrete wall body 1 and a frame body 2, and the frame body 2 is buried in the concrete wall body 1.

[0043] Reference Figure 1 and Figure 2After the workers install the frame body 2 on the floor slab, shear wall formworks are installed on both sides of the frame body 2; a receiving cavity is enclosed between the two oppositely arranged shear wall formworks to receive the concrete of the shear wall; after the concrete solidifies, a concrete wall body 1 is formed.

[0044] In this embodiment, the concrete uses EPS (polystyrene particles) concrete with good thermal and sound insulation properties to wrap the frame 2, so that the concrete wall 1 and the frame 2 work together, which greatly improves the integrity and fire resistance of the structure. In other embodiments, the concrete can also use high-strength concrete and lightweight concrete such as foam concrete; this application does not limit the specific type of concrete.

[0045] Reference Figure 1 and Figure 2 The frame body 2 includes a plurality of steel pipe columns 21 and a plurality of connection components 22, wherein the connection components 22 are used to connect adjacent steel pipe columns 21. Along the length direction of the concrete wall 1, a plurality of steel pipe columns 21 are arranged at intervals, and a chamber for containing concrete is provided in the steel pipe columns 21, and the steel pipe columns 21 and the concrete together form a steel pipe concrete column. Along the height direction of the concrete wall 1, a plurality of connection components 22 are arranged at intervals; the connection components 22 are fixedly connected to the steel pipe columns 21, and the connection components 22 and the steel pipe columns 21 form a frame body 2 with a mesh structure.

[0046] Reference Figure 2 and Figure 3 The steel pipe column 21 includes at least two single pipe columns 211. The single pipe columns 211 are hollow steel pipe structures. Several single pipe columns 211 are arranged at intervals along the width direction of the concrete wall 1, and a protective gap is provided between the single pipe columns 211 and the outer peripheral surface of the concrete wall 1. In the present application, along the width direction of the concrete wall 1, the steel pipe column 21 includes two relatively arranged single pipe columns 211; the two single pipe columns 211 are fixedly connected by a connecting assembly 22. The single pipe column 211 and the concrete form a steel pipe concrete structure, and along both sides of the thickness direction of the shear wall, a plurality of steel pipe concrete structures are provided on both sides of the shear wall, thereby improving the compressive strength of the concrete on both sides of the shear wall body, improving the ability of the shear wall to resist out-of-plane bending deformation, and improving the seismic performance of the shear wall. While the workers are installing the frame body 2, the seismic performance of the shear wall is also improved simultaneously.

[0047] The boundary conditions of the area where the concrete wall 1 contacts the single pipe column 211 change, which makes it easy for cracks to appear on the periphery of the concrete wall 1 and the single pipe column 211, thereby affecting the seismic performance and appearance of the shear wall.

[0048] Reference Figure 3 and Figure 4Along the length direction of the concrete wall 1, a plurality of first connecting holes 2111 are provided on both sides of the single pipe column 211; the connecting holes are arranged at intervals along the height direction of the concrete wall 1, and the first connecting holes 2111 are used for concrete to pass through. And the first connecting holes 2111 on both sides of the single pipe column 211 are arranged alternately. On the one hand, by providing a plurality of first connecting holes 2111 on the single pipe column 211, the concrete inside the single pipe column 211 and the concrete of the concrete wall can flow with each other, thereby facilitating on-site construction by the staff. On the other hand, the concrete in the single pipe column 211 and the concrete in the concrete wall 1 are condensed into one, thereby improving the integrity between the concrete wall 1 and the frame body 2; thereby reducing the cracking of the concrete wall 1 in the single pipe body area.

[0049] Reference Figure 3 and Figure 4 The first connecting holes 2111 on both sides of the single pipe column 211 are staggered, which is convenient for construction workers and improves the integrity of the concrete wall 1 and the frame body 2; it can also improve the restraining effect of the single pipe column 211 on the internal concrete, so as to further improve the ability of the shear wall body to resist horizontal loads.

[0050] Reference Figure 2 and Figure 3 The connection assembly 22 includes a connection rod 221 and a fastener 222 . The fastener 222 is used to fix the single pipe columns 211 arranged in pairs, and the connection member is used to fix a plurality of steel pipe columns 21 .

[0051] Reference Figure 2 and Figure 3 Specifically, the fastener 222 includes two symmetrically arranged fastening plates 2221 and fastening bolts 2222. The fastening plates 2221 are provided with fixing grooves 22211, and the fixing grooves 22211 are used to accommodate the single pipe column 211. The fastening plates 2221 are provided with mounting holes, and the fastening bolts 2222 are sequentially inserted into the mounting holes. The fastening bolts 2222 are used to tie the two oppositely arranged fastening plates 2221 together, so that the two fastening plates 2221 clamp and fix the two single pipe columns 211. On the one hand, the position of the single pipe column 211 is fixed by the fastener 222, which is convenient for the installation of the staff and improves the construction speed of the shear wall. On the other hand, the fastener 222 has a tying effect on the single pipe columns 211 on both sides, which can limit the single pipe columns 211 and concrete on both sides of the width of the shear wall from bulging outward, thereby further improving the performance of the shear wall in resisting bending and shearing deformation and improving the seismic performance of the shear wall.

[0052] Reference Figure 2 and Figure 3The connecting rod 221 is a hollow steel pipe, which is horizontally arranged. There are a plurality of connecting rods 221, which are arranged at intervals along the vertical direction. In this embodiment, connecting rods 221 are arranged on both sides of the shear wall. The connecting rod 221 is fixedly connected to the single pipe column 211 by bolts, so that the staff can quickly install the frame body 2 and improve the construction speed of the shear wall.

[0053] Reference Figure 2 and Figure 3 Along the length direction of the connecting rod 221, the connecting rod 221 is provided with a plurality of second connecting holes 2211 at intervals, and the second connecting holes 2211 are used for concrete to pass through. By providing a plurality of second connecting holes 2211 on the connecting rod 221, the concrete in the concrete wall 1 can enter the connecting rod 221 through the second connecting holes 2211, thereby improving the connection strength between the concrete wall 1 and the connecting rod 221, further improving the integrity between the concrete wall 1 and the frame body 2, and improving the ability of the shear wall body to resist horizontal loads.

[0054] During the construction of the shear wall structure, the staff can embed the steel connectors in the floor slab, and the staff can use the fasteners 222 to assemble the two single pipe columns 211 into the steel pipe column 21. Then, the staff welds and fixes the single pipe column 211 in the steel pipe column 21 with the embedded steel connectors; then, the staff bolts and fixes the connecting rod 221 with the single pipe column 211. Thus, through the assembly of the steel pipe column 21 connection assembly 22, it is convenient for the staff to quickly install the frame body 2, reduce the manpower input, and improve the construction efficiency of the shear wall.

[0055] The implementation principle of a shear wall structure and its construction method in the embodiment of the present application is: The frame body 2 inside the shear wall is assembled from steel pipe columns 21 and connection components 22. The steel pipe columns 21 and the connection components 22 can be prefabricated in a factory, which has obvious industrial characteristics. In addition, during the on-site construction process, the frame body 2 has a certain rigidity and bearing capacity, which is convenient for on-site installation by the staff, reduces labor input, and improves the construction speed of the shear wall.

[0056] At the same time, the steel tube column 21 and the concrete form a steel tube concrete column, and the steel tube column 21 has a strong restraining effect on the concrete inside to improve the compressive performance of the concrete in the shear wall structure; at the same time, the steel tube concrete column has good ductility and energy absorption capacity under the action of compression, bending and shear cyclic loads, thereby improving the ability of the shear wall structure to resist horizontal loads.

[0057] Example 2 This embodiment 2 discloses a construction method of a shear wall structure in embodiment 1, comprising the following steps: Install the frame body 2: embed steel connectors on the floor slab, use fasteners 222 to assemble two single pipe columns 211 into a steel pipe column 21, weld and fix the single pipe column 211 to the embedded steel connectors; and bolt and fix the connecting rod 221 to the single pipe column 211.

[0058] Install shear wall formwork: Install shear wall formwork on both sides of frame body 2.

[0059] Pouring concrete: insert an air guide tube into the steel pipe column 21, pour concrete into the single pipe column 211 while removing the air guide tube; pour concrete between the two shear wall templates to form a concrete wall 1. When the staff pours concrete into the single pipe column 211, the air guide tube can be used to timely discharge the air at the bottom of the single pipe column 211, thereby improving the density of the concrete in the single pipe column 211. The air guide tube can be a tubular structure such as a small steel pipe or a plastic hose.

[0060] Demoulding and curing: remove the shear wall formwork and water and cure to the concrete design strength.

[0061] Example 3 The difference between this embodiment 2 and embodiment 1 is that: When the shear wall is subjected to a large earthquake, the connecting rod 221 and the concrete wall 1 will produce a bonding and sliding effect, so that the connecting rod 221 and the concrete wall 1 will move relative to each other. Therefore, this embodiment further improves the shear wall structure.

[0062] Reference Figures 5 to 7 Along the length direction of the connecting rod 221, the connecting rod 221 is provided with a plurality of third connecting holes 2212 at intervals. The shear wall structure also includes a plug-in steel bar 3, the plug-in steel bar 3 includes a plug-in portion 31 and abutting portion 32, the plug-in portion 31 and the abutting portion 32 are integrally formed, the plug-in portion 31 is inserted into the third connecting hole 2212, the plug-in portion 31 is buried in the concrete wall 1, and the abutting portion 32 abuts against the connecting rod 221. That is, by inserting the plug-in steel bar 3 into the connecting rod 221, and partially burying the plug-in steel bar 3 in the concrete wall 1, the restraining effect on the connecting rod 221 is improved through the coordinated cooperation between the plug-in steel bar 3 and the concrete wall 1; the slippage between the connecting rod 221 and the concrete wall 1 can be reduced, the integrity of the concrete wall 1 and the frame body 2 can be improved, and the overall seismic performance of the shear wall can be improved.

[0063] In this embodiment, the abutment portion 32 and the connecting rod 221 are fixed by binding with thin iron wire; in other embodiments, after the worker inserts the inserted steel bar 3 into the connecting rod 221, the worker can also change the shape of the inserted steel bar 3 by bending the inserted steel bar 3 to prevent the inserted steel bar 3 from being separated from the connecting rod 221 when pouring concrete.

[0064] Example 4 The difference between this embodiment 3 and embodiment 1 is that: Reference Figures 8 to 10 The shear wall structure further includes a mild steel damper 4, and a plurality of mild steel dampers 4 are provided, and the plurality of mild steel dampers 4 are arranged at intervals along the length direction of the connecting rod 221. In this embodiment, two mild steel dampers 4 are arranged horizontally at intervals, and two groups of mild steel dampers 4 are arranged vertically; the opening directions of the two mild steel dampers 4 on the same horizontal plane are arranged oppositely to improve the self-reset performance of the mild steel damper 4.

[0065] Reference Figures 9 to 11 The mild steel damper 4 includes a first straight portion 41 , an arc portion 42 and a second straight portion 43 connected in sequence; the first straight portion 41 and the second straight portion 43 are arranged relatively parallel to each other; the first straight portion 41 is fixed to the connecting rod 221 with bolts.

[0066] Reference Figures 9 to 11 In addition, the shear wall structure further includes a rubber gasket 5, which is bonded to both inner and outer sides of the mild steel damper 4, and provides a deformation space for the mild steel damper 4 to deform.

[0067] The implementation principle of a shear wall structure and its construction method in the embodiment of the present application is: When the shear wall is subjected to a large earthquake, the connecting rod 221 and the concrete wall 1 will produce a bonding and sliding effect, so that the connecting rod 221 and the concrete wall 1 will move relative to each other.

[0068] Since one side of the mild steel damper 4 is bolted to the connecting rod 221, and the other side of the mild steel damper 4 is embedded in the concrete wall 1, when relative sliding occurs between the connecting rod 221 and the concrete wall 1, the connecting rod 221 will pull the first straight portion 41 of the mild steel damper 4 to slide, so that the first straight portion 41 and the second straight portion 43 pull the middle arc portion 42 to undergo elastic-plastic bending deformation, thereby dissipating seismic energy and further improving the seismic performance of the shear wall.

[0069] Example 5 The difference between this embodiment 5 and embodiment 3 is that: Reference Fig.12 and Fig.13 The shear wall structure also includes two secondary steel meshes 6. Along the width direction of the shear wall, the two secondary steel meshes 6 are arranged on both sides of the frame body 2, and the secondary steel meshes 6 are fixedly connected to the frame body 2.

[0070] Reference Fig.13The secondary steel mesh 6 includes a plurality of transverse secondary steel bars 61 and a plurality of longitudinal secondary steel bars 62. The transverse secondary steel bars 61 are parallel to the ground, and the plurality of transverse secondary steel bars 61 are arranged at intervals. The longitudinal secondary steel bars 62 are perpendicular to the ground, and the plurality of transverse secondary steel bars 61 are arranged at intervals.

[0071] The frame body 2 structure has great rigidity, so after the workers assemble the frame body 2, they can use small iron wires to tie and fix the transverse secondary steel bars 61 and the longitudinal secondary steel bars 62 to the frame body 2, which is convenient for the workers to operate.

[0072] By adding a secondary steel mesh 6 to the outer periphery of the frame body 2, the degree of uneven stress distribution inside the shear wall concrete caused by the interaction between the steel bars and the concrete is reduced, thereby reducing the influence of the interaction between the main steel bars and the concrete on the maximum average compressive stress of the concrete in the shear wall, alleviating the concrete softening phenomenon, and achieving the purpose of improving the shear wall's destructive strength.

[0073] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
