Description

Technical Field

[0001] This invention relates to the field of shear wall technology, and in particular to a steel plate shear wall structure and a construction method for the shear wall. Background Technology

[0002] Existing shear walls are mostly reinforced concrete shear walls and ordinary steel plate shear walls. The former relies on on-site casting, which has a long construction cycle and is greatly affected by the environment; the latter is often connected by bolts or welding to support the structure and is mostly used for resisting lateral forces in buildings. In modular buildings, temporary supports are required to ensure the stability of transportation and installation.

[0003] The existing technology has obvious drawbacks: First, traditional steel plate shear walls require additional welding of temporary supports during transportation, which must be removed before installation. This not only generates a large amount of on-site cutting and grinding work, but also easily damages the wall structure. Furthermore, the support components have a low reuse rate, increasing construction costs. Second, the connection between modules relies heavily on manual calibration and lacks adjustable limiting mechanisms. During transportation, the wall panels are prone to shifting due to bumps, affecting the accuracy of subsequent assembly. Third, the existing structure is difficult to achieve the transformation from "stable transportation to installation and storage". The removal of temporary supports easily leads to wasted space, making it particularly unsuitable for scenarios such as nuclear power plants where structural accuracy and space utilization are critical.

[0004] Based on this, a steel plate shear wall structure and a construction method for the shear wall are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a steel plate shear wall structure and a construction method for the shear wall in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A steel plate shear wall structure includes a wall panel, a connecting frame connected to the outer side of the wall panel, a deflection shaft connected to the connecting frame, a deflection bar rotatably connected to the deflection shaft, a fixed seat provided on one side of the connecting frame, a fixed rod connected to the fixed seat, a limit ring connected to the fixed rod, and a limiting mechanism for stabilizing the connection between the wall panel and the fixed rod connected to the deflection bar.

[0008] Preferably, a concealed column is connected to the connecting frame, and the concealed column is connected through the wall panel.

[0009] Preferably, the two ends of the deflection shaft are fixedly connected to fixing clips, and the fixing clips are fixedly connected to the connecting frame.

[0010] Preferably, the fixing base has a fixing hole.

[0011] Preferably, the limiting mechanism includes an inner clamp and an outer clamp. One side of the inner clamp is connected to an insert block, one end of the insert block is inserted into the connecting frame, one end of the deflection bar is connected to an inner threaded sleeve, the inner threaded sleeve is connected to a screw rod, one end of the screw rod is rotatably connected to a fastening tube, the fastening tube is fixedly connected to the outer clamp, and the other end of the screw rod is connected to a hexagonal end.

[0012] Preferably, the insert is connected to an abutment block, and one side of the abutment block abuts against the connecting frame.

[0013] Preferably, a screw is connected to the outside of the inner threaded sleeve, the screw is connected through to one end of the deflection bar, and a nut is connected to the screw.

[0014] A construction method for a steel plate shear wall, employing a steel plate shear wall structure, includes the following steps:

[0015] S1: By rotating the hexagonal end, the screw causes the outer clamp and inner clamp to separate. Then, remove the nut to separate the inner threaded sleeve from the deflection bar.

[0016] S2: After removing the inner threaded sleeves on the outer side of multiple wall panels, loosen the connecting structure on the fixing hole of the fixing seat;

[0017] S3: Move the deflection bar to move the fixing rod away from the wall panel, then remove the insert block, move the deflection bar to fully retract it into the connecting frame, and then the entire wall panel structure can be assembled to the construction position.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. This application replaces the traditional temporary welded support by adopting a combination structure of "rotatable deflection bar + inner clamp-outer clamp limiting mechanism". This eliminates the need for on-site cutting and grinding, avoids damage to the wall structure, and the deflection bar, screw and other parts can be reused. At the same time, it realizes the form switching of "unfolding and limiting during transportation and folding and fitting during installation", which solves the problems of high dismantling cost, easy damage to structure and waste of space of traditional support.

[0020] 2. This application adopts a positioning structure of "fixed rod + limit ring + adjustable screw" and uses the fixing holes on the fixed seat to achieve a stable connection. During transportation, the wall panel position can be locked by the limit mechanism to avoid wall panel displacement caused by bumps. During installation, there is no need for repeated manual calibration, which solves the problems of low assembly accuracy and easy displacement of traditional module connection.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-4 The present invention provides a technical solution:

[0029] A steel plate shear wall structure includes a wall panel 1, a connecting frame 2 connected to the outer side of the wall panel 1, a deflection shaft 13 connected to the connecting frame 2, and a deflection bar 8 rotatably connected to the deflection shaft 13. The deflection bar 8 has a retractable and expandable structure, which allows the wall panel 1 to be structurally switched as needed. A fixing seat 4 is provided on one side of the connecting frame 2. The fixing seat 4 has a detachable structure and can remain fixed when connected. This structure is the key to ensuring that the position of the wall panel 1 does not shift during transportation. A fixing rod 5 is connected to the fixing seat 4, and a limit ring 6 is connected to the fixing rod 5. A limiting mechanism for stabilizing the connection between the wall panel 1 and the fixing rod 5 is connected to the deflection bar 8.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, a hidden column 3 is connected to the connecting frame 2. The hidden column 3 is connected through the wall panel 1. By setting the hidden column 3, the connection between the connecting frame 2 and the wall panel 1 can be effectively guaranteed, and the wall panel 1 can be prevented from deforming during use.

[0031] Specifically, such as Figure 2 and Figure 3As shown, the two ends of the deflection shaft 13 are fixedly connected to the fixing clips 7, which are fixedly connected to the connecting frame 2. The fixing clips 7 are used to stabilize the connection between the deflection shaft 13 and the connecting frame 2, thereby enhancing the firmness of the connection between the two structures.

[0032] Specifically, such as Figure 1 As shown, the fixed base 4 has a fixing hole 12, which can be connected to bolts and other structures to ensure a stable connection between the transport planes of the fixed base 4.

[0033] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the limiting mechanism includes an inner clamp 14 and an outer clamp 17. An insert block 15 is connected to one side of the inner clamp 14. One end of the insert block 15 is inserted into the connecting frame 2. The connection of the inner clamp 14 is stabilized by setting the insert block 15. One end of the deflection bar 8 is connected to an inner threaded sleeve 11. The inner threaded sleeve 11 is connected to a screw rod 9. One end of the screw rod 9 is rotatably connected to a retaining tube 18. The retaining tube 18 is inseparable from the screw rod 9 and can rotate around one end of the screw rod 9. The retaining tube 18 is fixedly connected to the outer clamp 17. The other end of the screw rod 9 is connected to a hexagonal end 10. When the screw rod 9 is rotated, it can drive the outer clamp 17 to move towards the inner clamp 14, thereby achieving the effect of clamping the outer clamp 17 and the inner clamp 14 on the fixed rod 5. With the help of the limiting ring 6, the inner clamp 14 and the outer clamp 17 cannot move up and down, thereby stabilizing the connection position of the wall panel 1.

[0034] Specifically, such as Figure 2 and Figure 4 As shown, an abutment block 16 is connected to the insert block 15. One side of the abutment block 16 abuts against the connecting frame 2. By setting the abutment block 16, the position of the insert block 15 connected to the connecting frame 2 is limited.

[0035] Specifically, such as Figure 4 As shown, a screw 19 is connected to the outside of the inner threaded sleeve 11. The screw 19 is connected through one end of the deflection bar 8. A nut 20 is connected to the screw 19. The nut 20 stabilizes the state of the inner threaded sleeve 11 connected to the deflection bar 8. The deflection bar 8 is in the connected state of being sleeved on the screw 19.

[0036] In summary, the steel plate shear wall structure and construction method provided in this embodiment allow for the following when transporting the steel plate shear wall: wall panels 1 can be moved to a fixed position, ensuring they are stacked from bottom to top. Then, the deflection strips 8 on one side of each wall panel 1 are deflected, and insert blocks 15 are installed between the deflection strips 8. The insert blocks 15 are ensured to be inserted into the connecting frame 2, with the outer inclined surface of the insert block 15 abutting against the inclined surface of the deflection strip 8. Simultaneously, the abutting block 16 abuts against the connecting frame 2. Move the fixing rod 5 to mate with the inner clamp 14, ensuring that the inner clamp 14 is clamped between the limiting rings 6 of the fixing rod 5. The fixing seat 4 connected to the lower end of the fixing rod 5 is fixedly connected to the ground. Then, the inner threaded sleeve 11 is connected to one end of the deflection bar 8 by the nut 20, so that the outer clamp 17 faces the inner clamp 14. At this time, rotate the hexagonal end 10 to move the outer clamp 17 towards the inner clamp 14 until the inner clamp 14 and the outer clamp 17 are tightly clamped in the fixing rod 5. The structural connection of the outer side of each wall panel 1 is completed in sequence.

[0037] When the wall panel 1 is transported to its destination, the outer clamp 17 and the fixing rod 5 are disassembled in sequence, and the deflection strip 8 is stored in the connecting frame 2 so as not to interfere with the hoisting and installation of the wall panel.

[0038] By setting the fixing rod 5 and the limiting ring 6, the stability of the wall panel 1 can be effectively protected during transportation. It can effectively resist the swaying of sea transportation and the impact of bumps during land transportation, effectively reduce the probability of deformation of the wall panel 1 during transportation, improve the quality and safety of the wall panel 1 during subsequent use, and enable the wall panel to switch between dual-form structures, thereby effectively dealing with transportation and installation. The structure is easy to disassemble and assemble, and the disassembled parts can be reused. The deflection strip 8 can be tightly attached to the connecting frame, so as not to occupy the wall structure and avoid the space waste and secondary processing costs after the temporary support is removed in the existing technology.

[0039] The above description of the embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
