[0002] With the development of my country's economy and science and technology, super high-rise buildings are becoming increasingly popular. As the building heights are getting higher and higher, the structural forms are becoming more and more diverse. The traditional reinforced concrete structure system can no longer meet the needs of high-rise development. In the past 10 years, steel-concrete hybrid structures have been adopted. This structural system combines the advantages of steel and concrete structures, with high bearing capacity, good ductility, and strong deformation capacity, thus having strong wind and earthquake resistance. Summary of the invention

[0003] The present invention aims to overcome the defects of the prior art and provide a high-precision processing and manufacturing method for a multi-cavity steel plate shear wall to solve the problem of poor ductility and energy dissipation capacity of traditional reinforced concrete shear walls.

[0004] In order to solve the above-mentioned technical problems, the present invention is achieved as follows: A high-precision processing and manufacturing method for a multi-cavity steel plate shear wall, characterized in that it comprises the following steps: Step 1: Assemble and weld the panel and vertical stiffening plate; Step 2: L-shaped structure production; Step 3: U-shaped structure production; Step 4: BOX structure production; Step 5: Make the remaining inner partitions and vertical stiffening plates.

[0005] The high-precision processing and manufacturing method of a multi-cavity steel plate shear wall is characterized in that step one specifically comprises: welding the vertical stiffening plate and the panel between the upper transverse diaphragm and the lower transverse diaphragm respectively, and welding the local bolts inside the box.

[0006] The high-precision processing and manufacturing method of a multi-cavity steel plate shear wall is characterized in that step two specifically comprises: assembling the middle transverse partition plate, the panel plate and the side plate into an L-shaped structure, and welding them.

[0007] The high-precision processing and manufacturing method of a multi-cavity steel plate shear wall is characterized in that step three specifically comprises: assembling a U-shaped structure, and welding the tie plates between the upper transverse diaphragm and the lower transverse diaphragm to the vertical stiffening plates in sequence.

[0008] The high-precision processing and manufacturing method of a multi-cavity steel plate shear wall is characterized in that step four specifically comprises: making another side panel and a U-shaped box into a BOX structure, and a welder enters the box to complete the welding of the unwelded edge of the middle cross partition by single-sided welding with a pad.

[0009] The high-precision processing and manufacturing method of a multi-cavity steel plate shear wall is characterized in that a U-shaped structure is formed by a combination structure of a vertical panel of a fixture, an internal fixed stiffening plate, an external panel and external fastening bolts. The gap between the internal fixed stiffening plate and the external panel is the thickness of the steel plate strong wall plate +, so that the components can be smoothly embedded inside it, and the cross-sectional dimensions are guaranteed not to change during the manufacturing process by relying on the support of the internal fixed stiffening plate and the fastening force of the external bolts; a U-shaped fixture is used for the production of two components at the same time, and the bottom of the upper wall and the top of the lower wall are connected at the same time, so that the cross-sectional dimensions of the on-site interface parts are consistent, and the components are smoothly installed on-site.

[0010] The high-precision processing and manufacturing method of a multi-cavity steel plate shear wall is characterized in that step five specifically includes: assembling and welding the upper transverse diaphragm and the lower transverse diaphragm, single-sided welding of the upper transverse diaphragm, the lower transverse diaphragm, the panel and the side panel by leaving a gap and adding a gasket, and then respectively welding the upper transverse diaphragm, the lower transverse diaphragm and the internal vertical reinforcement through the transverse diaphragm hole; then the vertical reinforcements of the area below the lower transverse diaphragm and the area above the upper transverse diaphragm are respectively welded to the main body and the diaphragm, and the tie plate between the vertical reinforcements is welded to the vertical reinforcement, and finally the top process diaphragm is welded to complete the entire component manufacturing.

[0011] The beneficial effects of the present invention are as follows: It can be seen from the above technical scheme that the present application provides a high-precision processing and manufacturing method for a multi-cavity steel plate shear wall. The steel plate sandwich concrete shear wall is further developed on the basis of the steel-concrete hybrid structure system, and the reinforced concrete shear wall commonly used in the hybrid structure is changed to a sandwich steel plate composite shear wall with a steel structure as the main component. The sandwich steel plate composite shear wall can give full play to the advantages of both steel and concrete materials, improve the shortcomings of poor ductility and energy consumption capacity of traditional reinforced concrete shear walls, and has application advantages in steel-concrete composite structures. At the same time, the structure is convenient for factory management and production, and is easy to transport and install. The outer steel plate also serves as a concrete formwork during the construction stage, which simplifies the on-site construction process, can effectively improve the on-site construction quality and progress, and has considerable social and economic benefits.

[0013] The technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application. As Figure 1 、 2 shown: For the convenience of rapid and accurate on-site installation, such multi-chamber steel plate walls directly serve as formwork during concrete pouring. The wall thickness is mostly between 600~, the width of a single component is between 2400~, and it contains 4 horizontal partition plates and 2 vertical stiffening plates inside. The vertical stiffening plates are disconnected at the positions of the horizontal partition plates, and the vertical stiffening plates are tied together by batten plates.

[0014] As Figure 3 shown: The high-precision processing and manufacturing method of the multi-chamber steel plate shear wall includes the following steps: Step 1: Assembling and welding the panel and the vertical stiffening plate Weld the vertical stiffening plates and the panel respectively within the range between diaphragm 3 and diaphragm 4. As Figure 4 shown, the local stud welding inside the box is completed.

[0015] Step 2: Manufacturing the L-shaped structure Assemble diaphragm 1, diaphragm 2 with the panel and the side plate into the Figure 5 shown L-shaped structure and weld it.

[0016] Step 3: Manufacturing the U-shaped structure Conduct the assembly of the U-shaped structure, and successively weld the tie plates within the range between diaphragm 3 and diaphragm 4 to the vertical stiffening plates respectively. As Figure 6 、 7 shown.

[0017] Step 4: BOX structure production like Figure 8 As shown: another side panel and the U-shaped box are made into a BOX structure, and the welder enters the box to complete the welding of the unwelded edges of the partitions 1 and 2 by single-sided welding with pads.

[0018] For this type of standard section steel plate shear wall, since its cross-sectional dimensions and wall thickness are consistent throughout the entire building structure, this type of steel plate wall exists in large quantities. In order to speed up production efficiency and ensure cross-sectional dimensions, after the components form the BOX structure, the company's independently developed U-shaped clamps can be used to fix the ends of the BOX structure during the welding process of the four main welds. Fig.10 , Fig.11 As shown, the steel plate wall is prevented from causing large cross-sectional deformation during the main weld welding process due to the thin wall thickness and low rigidity, high heat received by the main weld penetration welding, long weld length and long welding time.

[0019] The U-shaped structure is formed by the combination of the vertical panel of the fixture, the internal fixed stiffening plate, the external panel and the external fastening bolts. The gap between the internal fixed stiffening plate and the external panel is the thickness of the steel plate strong wall plate +, so that the components can be smoothly embedded inside it. The cross-sectional dimensions do not change during the manufacturing process by relying on the support of the internal fixed stiffening plate and the fastening force of the external bolts. The calculation ensures that the fastening force generated by the number and specifications of the bolts can ensure the stability of the steel plate strong cross-sectional dimensions, and the steel plate wall panel will not be deformed due to this fastening force.

[0020] A U-shaped fixture can be used in the production of two components at the same time, connecting the bottom of the upper wall and the top of the lower wall at the same time, so that the cross-sectional dimensions of the interface parts on site are consistent and the components can be installed smoothly on site.

[0021] Step 5: Production of remaining inner partitions and vertical stiffening plates Assemble and weld the diaphragm 3 and 4. The diaphragm 3 and 4 are welded to the panel and side panels on one side by leaving a gap and adding a gasket. Then, the diaphragm 3 and 4 are welded to the internal vertical reinforcement through the diaphragm hole. Then, the vertical reinforcements in the area below the diaphragm 4 and above the diaphragm 3 are welded to the main body and the diaphragm respectively. The tie plates between the vertical reinforcements are welded to the vertical reinforcements. Finally, the process diaphragm on the top is welded to complete the production of the entire component. Fig. 9 shown.

[0022] For this type of components, factories currently mostly use the conventional method of assembling a U-shaped structure and finally assembling a large panel for production, which makes the components prone to large cross-sectional deformation. The present invention can shorten the component processing cycle, reduce component welding deformation, ensure that the overall size of the component is qualified, and achieve high-precision production of the multi-cavity steel plate wall by optimizing the assembly and welding sequence of the multi-cavity steel plate wall.

[0023] The above are only embodiments provided for the present application and are not intended to limit the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
