[0011] As a further solution of the present invention, the inner diameter of the mounting hole in the peripheral restraining plate is the same as that in the web.

[0012] As a further scheme of the present invention, the concentric mechanism includes a mounting ring, which is rotatably connected to the screw rod, and the upper and lower ends of the mounting ring are fixedly connected with elastic telescopic rods, and the ends of the elastic telescopic rods are fixedly connected with arc plates, the curvature of the outer wall of the arc plate is the same as the curvature of the inner wall of the mounting hole, and the end of the nut is fixedly connected with a pressure rod, the axis of the pressure rod is provided with a through hole with the same diameter as the threaded hole of the nut, and the end of the pressure rod is provided with a chamfer, and the curvature of the pressure rod is the same as the curvature of the inner wall of the arc plate, and the mounting ring is provided with a limiting mechanism, and the limiting mechanism is used to control the feed amount to be the same during the tightening process of the nuts at both ends of the same limiting column.

[0019] 3. The inner diameters of the mounting holes on the outer constraint plate and the web are the same, so that after the mounting holes on the outer constraint plate and the web are aligned, a through hole with a constant inner diameter can be formed. In addition to being suitable for the tension bolts in the present invention, the through hole can also be used for traditional tension bolts (traditional tension bolts are mostly a double-headed screw with two nuts). This makes the installation restrictions of the outer constraint plate and the web of the present invention lower, the replaceability of related accessories higher, and in the actual installation process, several groups of tension bolts in the present invention can be selected as a pre-installation process for mutual positioning between the outer constraint plate and the web, and the other groups of mounting holes are connected and reinforced with traditional tension bolts.

[0020] 4.

Furthermore, during the installation process, workers only need to operate on one side of the web (i.e., the shear wall), further reducing the number of personnel used.

[0021] 5. The present invention enables the threaded sleeve to rotate synchronously with the nut by means of a snap-fitting manner, thereby controlling the limit rod to perform longitudinal movement corresponding to the rotation amplitude of the nut, and the process is stable and reliable.

DETAILED DESCRIPTION

[0031] See also Figure 1-5 , the present invention provides a technical solution: an assembled stiffened steel plate shear wall, comprising a web 11;

[0032] A plurality of vertically arranged stiffening ribs 12, wherein the stiffening ribs 12 are vertically and symmetrically welded to the front and rear side walls of the web 11;

[0033] A plurality of peripheral restraining plates 13, wherein the peripheral restraining plates 13 are respectively filled between adjacent stiffening ribs 12;

[0034] A plurality of mounting holes 14, wherein the plurality of mounting holes 14 are distributed in an array and penetrate the peripheral restraining plate 13 and the web 11 at the front and rear sides of the web 11;

[0035] A plurality of tension bolts are installed at the same group of mounting holes 14 and are used to fix the peripheral restraining plate 13 between the stiffening ribs 12 .

[0036] The peripheral constraint plate 13 needs to have properties such as high strength, high toughness, light weight, fire resistance, water resistance, and prefabrication; the peripheral constraint plate 13 is used not only to fill the space between the stiffening ribs 12 as required by the building, but also to provide out-of-plane constraints for the web 11 to prevent it from deforming out of the plane under the combined action of compression, bending and shear, thereby improving the load-bearing efficiency of the web 11; since there is no additional bonding between the peripheral constraint plate 13 and the web 11, the bolted connection structure is also convenient for disassembling the peripheral constraint plate 13 during the subsequent steel recycling, thereby reducing the steel recycling cost; from the structure of the new prefabricated stiffened steel plate shear wall, it can be seen that this type of shear wall can be industrialized and assembled; in summary, the new prefabricated stiffened steel plate shear wall has the advantages of high performance, assembly, and easy recycling, which is in line with the current development trend of residential steel structures in my country and is suitable for use in multi-story steel structure residential buildings.

[0037] Compared with other steel plate shear walls and steel-concrete composite shear walls, the new prefabricated stiffened steel plate shear wall has the following advantages: (1) It is a pure steel system, which is easy to recycle materials and has a high steel reuse rate, which is in line with the national "dual carbon" strategic development direction; (2) The filling peripheral restraint plate is prefabricated in the factory and does not require concrete pouring, which makes on-site construction fast and less polluting; (3) The edge components on both sides are open sections, which makes it easy to set upper and lower docking nodes, beam-column nodes, etc.; (4) The use of peripheral restraint plates solves the problem of low out-of-plane stiffness and torsional stiffness of traditional stiffened steel plate shear walls; (5) The number of stiffening ribs is small, and the amount of welding is reduced; (6) The spacing between stiffening ribs can correspond to the module of the peripheral restraint plate and the floor decking plate, thereby improving the overall constructability of the structure.

[0038] As a further solution of the present invention, the tension bolt includes a limit column 21, which is installed in the mounting hole 14 on the web 11. The front and rear ends of the limit column 21 are fixedly connected with a screw 22, and the screw 22 is provided with a concentric mechanism. The ends of the screw 22 are threadedly connected with a nut 23. The maximum outer diameter of the screw 22 and the concentric mechanism is smaller than the inner diameter of the mounting hole 14 in the peripheral constraint plate 13. During the tightening process, the nut 23 will drive the maximum outer diameter of the concentric mechanism to expand to the same as the inner diameter of the mounting hole 14, so that the mounting holes 14 on the web 11 and the peripheral constraint plate 13 are aligned.

[0039] First, insert the limit columns 21 into the mounting holes 14 on the web 11 respectively, and then hang the peripheral constraint plate 13 on multiple screws 22. At this time, since the outer diameters of the screws 22 and the concentric mechanism are smaller than the inner diameter of the mounting holes 14, the hanging is not prone to jamming. Then, tighten the nuts 23 on the screws 22 on both sides of the limit columns 21 at the same time, and the tightening directions of the two nuts 23 are opposite. During the tightening process, the maximum outer diameter of the concentric mechanism expands to the same as the inner diameter of the mounting hole 14, so that the mounting holes 14 on the web 11 and the peripheral constraint plate 13 are aligned, thereby completing the adjustment of the position of the peripheral constraint plate 13.

[0040] Since there are multiple groups of aligned mounting holes 14 between the peripheral constraint plate 13 and the web 11, the present invention first uses a screw 22 with an outer diameter smaller than the inner diameter of the mounting hole 14 and a concentric mechanism to pre-install the peripheral constraint plate 13, and then uses the concentric mechanism to align the mounting holes 14 on the web 11 and the peripheral constraint plate 13 to complete the final installation of the peripheral constraint plate 13, thereby increasing the installation efficiency of the peripheral constraint plate 13.

[0041] As a further solution of the present invention, the inner diameter of the peripheral restraining plate 13 is the same as the inner diameter of the mounting hole 14 in the web 11 .

[0042] The inner diameters of the mounting holes 14 on the outer constraint plate 13 and the web 11 are the same, so that after the outer constraint plate 13 and the mounting holes 14 on the web 11 are aligned, a through hole with a constant inner diameter can be formed. In addition to being suitable for the tension bolts in the present invention, the through hole can also be used for traditional tension bolts (traditional tension bolts are mostly a double-headed screw with two nuts). This makes the installation restrictions of the outer constraint plate 13 and the web 11 of the present invention lower, and the replaceability of related accessories higher. In addition, in the actual installation process, several groups of tension bolts in the present invention can be selected as the pre-installation process for the mutual positioning between the outer constraint plate 13 and the web 11, and the other groups of mounting holes 14 are connected and reinforced with traditional tension bolts.

[0043] As a further scheme of the present invention, the concentric mechanism includes a mounting ring 31, which is rotatably connected to the screw rod 22. The upper and lower ends of the mounting ring 31 are fixedly connected with elastic telescopic rods 32, and the ends of the elastic telescopic rods 32 are fixedly connected with arc plates 33. The curvature of the outer wall of the arc plate 33 is the same as the curvature of the inner wall of the mounting hole 14. The end of the nut 23 is fixedly connected with a pressure rod 34. The axis of the pressure rod 34 is provided with a through hole with the same diameter as the threaded hole of the nut 23. The end of the pressure rod 34 is provided with a chamfer 35. The curvature of the pressure rod 34 is the same as the curvature of the inner wall of the arc plate 33. The mounting ring 31 is provided with a limiting mechanism, and the limiting mechanism is used to control the feed amount to be the same during the tightening process of the nuts 23 at both ends of the same limiting column 21.

[0044] During the tightening process of the nut 23, the screw 22 is first inserted into the pressure rod 34 and connected with the threaded hole of the nut 23. At the same time, the chamfer 35 at the end of the pressure rod 34 is inserted between the two arc plates 33, and then the nut 23 is rotated to move the nut 23 toward the web 11. During this process, as the pressure rod 34 is gradually inserted between the two arc plates 33, the maximum outer diameter of the chamfer 35 located between the two arc plates 33 gradually increases, causing the two arc plates 33 to move away from each other until the chamfer 35 part of the pressure rod 34 completely enters between the two arc plates 33, and the two arc plates 33 are fully opened, further making the two arc plates 33 completely fit the inner wall of the mounting hole 14 on the peripheral constraint plate 13. At this time, the mounting hole 14 is coaxial with the screw 22, and the corresponding web 11 and the mounting hole 14 on the peripheral constraint plate 13 are coaxial, and the peripheral constraint plate 13 reaches the predetermined position.

[0045] As a further solution of the present invention, the limiting mechanism includes a longitudinally arranged limiting rod 41, the limiting rod 41 passes through the limiting column 21 and extends to the screw 22 on the other side of the limiting rod 41, the limiting rod 41 is transmission-connected with a control mechanism at the screw 22 on the other side of the limiting column 21, and the control mechanism can control the limiting rod 41 to move toward the other side of the limiting column 21 as the nut 23 on the other side of the limiting column 21 is gradually tightened; a push ring 42 is provided at the end of the limiting column 21, the push ring 42 is fixedly connected with a sliding rod 43, the sliding rod 43 is elastically slidably connected with the mounting ring 31, the sliding rod 43 is fixedly connected with a push plate 44, and the push plate 44 can hinder the feeding of the pressure rod 34.

[0046] (refer to Figure 7When the nut 23 is engaged with the screw rod 22 and begins to be tightened, the end of the pressure rod 34 is at a certain distance from the push plate 44. As the nuts 23 at both ends of the limiting column 21 are continuously tightened, the end of the pressure rod 34 approaches the end of the push plate 44. At the same time, the limiting rod 41 drives the push plate 44 to continuously move away from the pressure rod 34 as the nut 23 on the same side of the corresponding control mechanism is tightened; during this process, if the nut 23 at one end of the limiting column 21 (hereinafter referred to as the first nut 23) does not rotate relative to the corresponding screw rod 22 (hereinafter referred to as the first screw 22), that is, the first nut 23 is not tightened, the limiting rod 41 (hereinafter referred to as the second limiting rod 41) corresponding to the first nut 23 will not move away from the corresponding pressure rod 34 (hereinafter referred to as the second pressure rod 34). Furthermore, the nut 23 (hereinafter referred to as the second nut 23) corresponding to the first nut 23 will be blocked by the push plate 44 corresponding to the second limiting rod 41 and cannot be tightened, so that during the tightening process, only the first nut 23 and the first screw rod 22 can rotate relative to each other. The first nut 23 is moved so that the first nut 23 is tightened, and the nuts 23 at both ends of the limit column 21 are prevented from being stuck during the tightening process, causing one of the nuts 23 to be unable to perform the normal tightening action, resulting in the tightening work being unable to proceed normally (specifically, if the first nut 23 and the first screw rod 22 are stuck to each other, the corresponding first nut 23 and the first screw rod 22 cannot rotate relative to each other, that is, the first nut 23 and the first screw rod 22 are relatively stationary. At this time, in the process of rotating the first nut 23 and the second nut 23 at the same time, only the second nut 23 will rotate relative to the corresponding screw rod 22, and the corresponding limit column 21 and the two screws 22 thereon will tend to move toward the direction of the second nut 23. Since the outer diameter of the limit column 21 is the same as the mounting hole 14 on the peripheral constraint plate 13, after the second nut 23 is rotated to a certain extent, the limit column 21 is easy to pass through the mounting hole 14 on the peripheral constraint plate 13 and move in the direction of the second nut 23, causing the limit column 21 to separate from the web 11).

[0047] The present invention uses a limiting mechanism to force the two nuts 23 to rotate alternately relative to the screw rod 22. In actual use, the rotation of one of the nuts 23 can be fixed by adding a related fixture, and then only the other nut 23 is rotated to complete the tightening of the tension bolt. Furthermore, during the installation process, workers only need to operate on one side of the web 11 (i.e., the shear wall), further reducing the number of personnel used.

[0048] As a further solution of the present invention, the control mechanism includes a threaded sleeve 51, which is rotatably connected to the side wall of the limiting column 21, and the threaded sleeve 51 is threadedly connected to the screw 22. The thread directions of the front and rear sides of the screw 22 are opposite, and the limiting rod 41 connected to the push plate 44 corresponding to the threaded sleeve 51 is rotatably connected to the side wall of the threaded sleeve 51. The threaded sleeve 51 is transmission-connected with a synchronization mechanism, and the synchronization mechanism is used to synchronize the rotation of the threaded sleeve 51 with the nut 23 relative to the screw 22.

[0049] As a further solution of the present invention, the synchronization mechanism includes two locking rods 61, and the two locking rods 61 are respectively longitudinally slidably connected to the left and right sides of the mounting ring 31, and the ends of the pressure rod 34 are provided with locking grooves 62 corresponding to the positions of the locking rods 61. The end of the mounting ring 31 is fixedly connected with a telescopic rod 63, and the telescopic rod 63 is fixedly connected to the end of the threaded sleeve 51.

[0050] In the process of aligning the nut 23 with the screw rod 22, the engaging groove 62 and the engaging rod 61 engage with each other, and further in the process of tightening the nut 23, the engaging rod 61 can drive the mounting ring 31 to rotate synchronously with the nut 23, and further the mounting ring 31 drives the threaded sleeve 51 to rotate synchronously with the nut 23 through the telescopic rod 63, so that the threaded sleeve 51 moves away from the limiting column 21, and then drives the limiting rod 41 corresponding to the limiting column 21 to move longitudinally.

[0051] The present invention enables the threaded sleeve 51 to rotate synchronously with the nut 23 by means of a snap-fitting manner, thereby controlling the limit rod 41 to perform longitudinal movement corresponding to the rotation amplitude of the nut 23, and the process is stable and reliable.
