Description

Technical Field

[0001] The invention relates to the technical field of building structures, and in particular to a concrete perforated shear wall module, a concrete modular shear wall structure system and an assembling method thereof. Background Art

[0002] With the transformation and upgrading of the construction industry, building industrialization has gradually become a hot topic of industry concern and research. Among them, modular buildings can best meet the requirements of building industrialization for the standardization, modularization, integration, flexibility and other characteristics of modern buildings. The main advantage of the existing modular structural system is the reduction of on-site construction, especially the significant reduction of on-site operations such as water and electricity decoration, which is conducive to improving construction quality and shortening the on-site construction period.

[0003] In the engineering application of modular structures, steel structures, wood structures, concrete structures, steel-wood hybrid structures and steel-concrete hybrid structures are mainly used. Among them, concrete modular structures are currently less used in the market and are technically difficult. There are also problems such as large wet work workload, difficulty in assembly construction, and difficulty in meeting the seismic requirements of high-rise buildings.

[0004] Since the reinforced concrete shear wall structure system is a structural system with high horizontal stiffness and earthquake resistance, shear wall structures are widely used in medium and high-rise buildings in my country, especially in residential buildings with great construction demand. Therefore, the concrete modular shear wall structure system is one of the key development directions of modular buildings in the future. At present, concrete frame modules and box-type modules are relatively widely used and have formed a relatively complete standard design system, while shear wall modules lack relevant applications.

[0005] The Chinese utility model patent building module and modular building with application number: CN201920710282.2 provides a building module and a modular building based on the building module. The module body includes at least 3 pipes running through the module body, each pipe is parallel to an edge of the building module body, and the 3 pipes are perpendicular to each other. The modular building includes a plurality of building modules, and the pipes of adjacent building modules are aligned with each other, and prestressed steel strands are passed through them, and the adjacent building modules are tensioned and fixed by the prestressed steel strands.

[0006] The building module body provided by the utility model does not explain whether the module itself has the ability to bear external loads, and the connection form between the modules is relatively simple, and the single prestressed steel strand connection node does not have high shear and bending resistance at the same time. Although the outer surface of the module body is provided with anti-slip grooves, the mechanical properties are still limited. At the same time, the specific embodiment of the building involves a high-rise earthquake-resistant building, but there is no effective connection node design to ensure the stiffness, ductility, energy consumption and other related mechanical properties of the overall structure.

[0007] The Chinese invention patent with application number: CN202410518294.0 is a concrete module and a fully prefabricated concrete modular building structure system. The concrete module body provided by the invention includes a shear wall blade, a partition wall, a top plate and a bottom plate. The shear wall blade is fixedly connected to the partition wall, and a first cavity for pouring concrete is provided inside the shear wall blade; a beam shell is provided at the top of the partition wall, and a second cavity for pouring concrete is provided inside the beam shell, and the second cavity is connected to the first cavity.

[0008] The module body provided by the invention has the ability to bear external loads, but the connection between the modules still adopts the traditional form of steel bar overlap and post-cast concrete, which inevitably creates many restrictions on the module prefabrication, transportation, lifting and other links. At the same time, with the increase of building height and floor plan area, the construction cost, construction difficulty and negative impact on the environment are significantly increased.

[0009] The Chinese invention patent with application number CN202410565873.0 provides a concrete modular building. The room module provided by the invention is made up of a plurality of splicing components, and adjacent splicing components are fixedly connected by protrusions and recesses arranged on their edges. The splicing components include a side wall unit and a top plate unit, the side wall unit is vertically connected to the top plate unit, and one side of the side wall unit and the top plate unit is evenly provided with multiple rows of mounting rings aligned. By arranging support beams to pass through the mounting rings on the side wall unit and the top plate unit in different directions, the strength between the connections of each unit is improved.

[0010] The room module provided by the invention does not specify whether the module itself has the ability to bear external loads. At the same time, the module itself is composed of multiple splicing parts, which increases the number of connection nodes and the amount of construction work. The internal connection of the module and the connection between modules all involve pouring concrete in reserved gaps, which cannot avoid the various disadvantages of the on-site pouring concrete construction method.

Figure 3 It is a connection diagram of the embedded screw-steel connection box in an embodiment of the present invention.

[0034] like Figure 1-3 As shown, the concrete perforated shear wall module 100 in this embodiment includes a shear wall panel 10 , a top panel 30 , a bottom panel and a connecting beam 20 .

[0035] The main body of the concrete perforated shear wall module 100 is made of reinforced concrete, and the length, width and height of the main body of the concrete perforated shear wall module 100 are respectively 7.2 meters long, 3.6 meters wide and 3 meters high; the thickness of the shear wall panel 10 and the connecting beam 20 is 120 mm, and the thickness of the top plate 30 is 150 mm.

[0036] The shear wall panel 10 is provided with holes at predetermined positions, and the holes are arranged in the same horizontal direction, so that the concrete hole shear wall module 100 can be assembled with other concrete hole shear wall modules 100 in the horizontal direction by bolts. The horizontal cross-section of the shear wall panel 10 at the corner is L-shaped. The holes on the short side wall panels of the shear wall panel 10 are used to reserve openings for doors and windows, and the holes on the long side wall panels prevent the shear wall from being too long.

[0037] The corresponding positions of the top and bottom of the shear wall panel 10 are respectively provided with matching embedded screws 33 and embedded steel connection boxes 40. The embedded screws 33 at the top of the shear wall panel 10 cooperate with the embedded steel connection boxes 40 at the bottom of the shear wall panel 10 of other concrete perforated shear wall modules 100, thereby realizing the vertical assembly of the concrete perforated shear wall modules 100. The main material of the shear wall panel 10 is reinforced concrete.

[0038] The top surface, bottom surface and outer surface of the shear wall panel 10 are all provided with shear keys that match each other. The shear keys include a convex key block 31, a concave key groove 32, a convex key strip 36 and a concave key strip 37. The top surface of the shear wall panel 10 is provided with a convex key block 31, and the bottom surface of the shear wall panel 10 is provided with a concave key groove 32 that matches the length, width and height of the convex key block 31. The convex key strips 36 and the concave key strips 37 on opposite sides of the shear wall panel 10 in the horizontal direction correspond to each other one by one.

[0039] The shear wall panel 10 has vertically embedded full-length pipes and horizontally reserved bolt holes. The embedded screw 33 is located in the middle of the convex key block 31. At the same time, an embedded steel connecting box 40 is arranged at a position corresponding to the embedded screw 33 on the bottom surface of the shear wall panel 10. Vertically adjacent shear wall panels 10 can be connected by extending the embedded screw 33 into the steel connecting box 40.

[0040] The steel connection box 40 is welded by five steel plates, including three side steel plates 41, a top steel plate 42 and a bottom steel plate 43. The five steel plates form a hollow rectangular parallelepiped with one side open. The bottom steel plate 43 is provided with a circular hole, and the aperture of the circular hole is slightly larger than the aperture of the embedded screw 33. A U-shaped steel bar 44 is arranged on the steel connection box 40, and the U-shaped steel bar 44 is welded to the side steel plate 41 to strengthen the concrete anchoring effect of the steel connection box 40 in the shear wall panel 10. The opening direction of the steel connection box 40 is the inner side of the module, forming an operating hand hole. After the embedded screw 33 is inserted into the steel connection box 40, a pad 45 and a nut 46 are arranged through the operating hand hole to tighten and strengthen the connection, and then the operating hand hole is filled with mortar.

[0041] The top plate 30 is disposed on the top of the shear wall panel 10 .

[0042] The bottom plate is arranged at the bottom of the shear wall panel 10 .

[0043] The connecting beam 20 is fixedly connected to the shear wall panel 10 .

Figure 5 It is a structural schematic diagram of the horizontal connection of concrete perforated shear wall modules in an embodiment of the present invention. Figure 6 It is a schematic diagram of the overall structure of the concrete modular shear wall structure system in an embodiment of the present invention.

[0045] like Figure 4-6 As shown, the concrete modular shear wall structure system includes a plurality of concrete perforated shear wall modules 100, and the concrete perforated shear wall modules 100 are sequentially assembled in the vertical direction and the horizontal direction to form the concrete modular shear wall structure system.

[0046] The assembly method of the concrete modular shear wall structure system is as follows:

[0047] The shear wall panels 10 are prefabricated in the factory and then hoisted at the construction site, wherein the adjacent concrete modular shear wall modules in the horizontal direction are aligned with the shear keys and the reserved bolt holes, and are fixed by bolts after splicing. The adjacent modules in the vertical direction are aligned with the shear keys and the reserved through-length channels, and are fixed by tensioning the prestressed tendons 34 and installing the nuts 46 of the screws 33 after splicing to form a concrete modular building structure system. The assembly of all modules of the building is completed by repeating the module installation steps in the horizontal direction and the module installation steps in the vertical direction. In this process, the vertical pipes that penetrate the wall panels inside the wall body of all shear wall panels 10 are aligned. After the assembly is completed, the prestressed tendons 34 are penetrated to connect all the vertical concrete perforated shear wall modules 100 to form a whole.

[0048] Functions and Effects of the Embodiments

[0049] According to the concrete perforated shear wall module, concrete modular shear wall and assembly method thereof involved in the present invention, the overall prefabrication of the perforated shear wall panels, top panels and bottom panels is completed in the factory to form a concrete perforated shear wall module that can be quickly installed on the construction site. The modules adopt the same design standards, and the required components and units are suitable for large-scale production in the factory, thereby ensuring the uniform quality of each concrete module and reducing economic costs.

[0050] The vertical connection node adopts a combination of screw rods + key blocks, and the horizontal connection node adopts a combination of bolts + key bars, which can better ensure the rigidity of the overall structure.

[0051] The module body provided by the present invention has the ability to bear external loads. The modules are assembled into an integral structure through connection node components that are reasonably constructed, easy to install, and have excellent performance, without the need for additional cast-in-place or prefabricated main structures.

[0052] The on-site operation of the present invention is basically dry operation, which is convenient for the production, transportation, installation and splicing of prefabricated components, fully avoiding various drawbacks of wet connection construction operations such as sleeve grouting and reserved hole grout anchors, reducing possible errors in manual operation, and effectively improving the integrity, safety and construction efficiency of modular buildings. At the same time, the shear wall modules and connection nodes have excellent mechanical properties and can be used in high-intensity areas or buildings with key seismic fortification, and are suitable for projects such as dormitories, hotels, and community renovations.

[0053] An L-shaped shear wall panel is set at the corner. The corner part is a whole instead of being connected by two shear wall panels, which can greatly improve the mold strength.
