Description

Technical Field

[0001] This utility model relates to the field of structural engineering technology, and in particular to a stiffened corrugated steel plate modular prefabricated high-rise steel structure shear wall system. It is a novel, fully modular high-rise steel structure stiffened corrugated steel plate shear wall system, which aims to explore an effective path for the engineering promotion and application of modular high-rise steel structures. Background Technology

[0002] Modular steel structures boast relatively high levels of prefabrication and assembly, aligning with the development trends and requirements of industrialized construction and green building. However, currently, modular steel structures are primarily used in multi-story buildings. Therefore, exploring the overall design methods and applicability of modular high-rise steel structures is of great significance. The development of modular steel structures into high-rise building structural systems mainly follows two paths: one is to adopt a fully modular steel structure system, incorporating lateral force-resisting components within the modular units to enhance the overall seismic performance; the other is to combine modular steel structures with traditional lateral force-resisting systems (shear wall structures or core tube structures).

[0003] However, both of these approaches have their drawbacks. For the first approach, due to the unique "double-beam" structural feature of modular steel structures, the vertical force transmission of the lateral force-resisting components (braces or steel plate walls) arranged within the modular units is discontinuous. This makes it difficult to form an effective overall lateral force-resisting system after the modular units are vertically stacked. Furthermore, modular steel structures are a specific structural form with highly prefabricated attributes. Combining them with traditional lateral force-resisting systems will, on the one hand, prevent the full realization of the advantages of this structural system, such as its green and environmentally friendly nature, short construction period, and labor savings; on the other hand, it will lead to a more complex force transmission mechanism and higher design and construction costs. In conclusion, the lack of a lateral force-resisting system that can be directly assembled into fully modular units is currently the main bottleneck restricting the development of modular high-rise steel structures. Utility Model Content

[0004] To address the aforementioned shortcomings, this utility model provides a reinforced corrugated steel plate modular prefabricated high-rise steel structure shear wall system.

[0005] The technical solution of this utility model is as follows: a stiffened corrugated steel plate modular prefabricated high-rise steel structure shear wall system, mainly composed of lateral force resisting module units 8 stacked vertically and formed by column-column connection and beam-beam connection; the lateral force resisting module unit 8 is formed by arranging stiffened corrugated steel plate walls in ordinary frame module unit 7.

[0006] The stiffened corrugated steel plate wall is composed of stiffening ribs 2 evenly arranged on both sides of a trapezoidal corrugated steel plate 1, and the stiffening ribs 2 are connected to the corrugated steel plate 1 by weld.

[0007] The stiffened corrugated steel plate wall is divided into vertical stiffened corrugated steel plate wall and horizontal stiffened corrugated steel plate wall according to the different placement of the corrugation direction. In the horizontal stiffened corrugated steel plate wall, the stiffening rib 2 is placed horizontally and the corrugation of the corrugated steel plate 1 is placed vertically. In the vertical stiffened corrugated steel plate wall, the stiffening rib 2 is placed vertically and the corrugation of the corrugated steel plate 1 is placed horizontally. When the width-to-height ratio of the corrugated steel plate 1 is large, the horizontal stiffened corrugated steel plate wall is used.

[0008] The stiffened corrugated steel plate wall is connected to the beam and column components in the ordinary frame module unit 7 by welds.

[0009] The column-to-column connection is specifically as follows: the lateral force resisting module units 8 are connected by grouting, so that the vertical connection of the module columns 4 is rigid.

[0010] The beam-beam connection is specifically as follows: the modular beams 3 connected to the stiffened corrugated steel plate wall are combined by high-strength bolts 11.

[0011] The method for constructing a prefabricated high-rise steel structure shear wall with stiffened corrugated steel plate modules involves inserting connectors 10 into the outer cylinder 9 of the lower lateral force resisting module unit before installing the upper lateral force resisting module unit 8. After stacking, grouting is performed through the reserved grouting holes 12 to form column-column grouting connection nodes 5. The module beams 3 connected to the stiffened corrugated steel plate wall are connected to each other by beam-beam bolts 6 using high-strength bolts 11.

[0012] The ordinary frame module unit 7 and the lateral force resisting module unit 8 are connected horizontally and vertically by welding the connector 10 onto the same horizontal connecting plate 13.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) This utility model proposes using stiffened corrugated steel plate walls as the core lateral resistance and energy dissipation component in the modular high-rise steel structure stiffened corrugated steel plate shear wall system. Stiffened corrugated steel plate walls have relatively low self-weight, and due to the restraining effect of the stiffening ribs, they possess excellent load-bearing capacity and energy dissipation performance, making them extremely suitable for modular high-rise steel structure buildings. Stiffened corrugated steel plate walls are mainly divided into two categories: horizontally stiffened corrugated steel plate walls and vertically stiffened corrugated steel plate walls. In horizontally stiffened corrugated steel plate walls, the stiffening ribs are placed horizontally, and the corrugations of the corrugated steel plates are placed vertically; in vertically stiffened corrugated steel plate walls, the stiffening ribs are placed vertically, and the corrugations of the corrugated steel plates are placed horizontally. When the width-to-height ratio of the wall panel is large, horizontally stiffened corrugated steel plate walls are preferable.

[0015] (2) This utility model proposes to combine the module beams between the lateral force resisting module units by bolt connection, which effectively solves the problem of discontinuous vertical force transmission of the lateral force resisting components in the existing technology, thereby ensuring that the lateral force resisting module units can build an effective overall lateral force resisting system after vertical stacking, and finally achieve the same deformation mode and force transmission mechanism as the traditional structure.

[0016] (3) The modular high-rise steel structure stiffened corrugated steel plate shear wall lateral force resisting system proposed in this utility model can be constructed by full module assembly. Compared with the construction method of combining modular steel structure and traditional lateral force resisting system, it can maximize the advantages of modular steel structure such as green environmental protection, short construction period and labor saving. Moreover, the structural force transmission mechanism is clearer and the design and construction costs are lower. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of this utility model are further described below with reference to the accompanying drawings and technical solutions.

[0032] The reinforced corrugated steel plate modular prefabricated high-rise steel structure shear wall proposed in this utility model is constructed by vertically stacking lateral force resisting modular units with reinforced corrugated steel plate walls, and by means of column-to-column and beam-to-beam connections.

[0033] In the prefabricated high-rise steel structure shear wall of stiffened corrugated steel plate modules, the stiffened corrugated steel plate wall is formed by uniformly arranging stiffening ribs on both sides of the trapezoidal corrugated steel plate wall, and the stiffening ribs are connected to the corrugated steel plate by welds. Due to the out-of-plane restraint effect of the stiffening ribs, the overall stability, load-bearing capacity, hysteretic performance, and low-cycle fatigue performance of the stiffened corrugated steel plate wall are significantly improved, making it an ideal lateral resistance and energy dissipation component.

[0034] In the above-mentioned stiffened corrugated steel plate modular prefabricated high-rise steel structure shear wall, the lateral force resisting module unit 8 refers to the structure formed by arranging stiffened corrugated steel plate walls in ordinary frame module units. The stiffened corrugated steel plate walls are connected to the beam and column members in the module unit by welds.

[0035] In the above-mentioned reinforced corrugated steel plate modular prefabricated high-rise steel structure shear wall, the column-column connection is to realize the vertical connection between the module units. The grouting connection method can be used to ensure that the vertical connection of the module columns can achieve the effect of rigid connection.

[0036] In the aforementioned prefabricated high-rise steel shear wall with stiffened corrugated steel plate modules, beam-beam connections are achieved by combining modular beams connected to the stiffened corrugated steel plate walls using high-strength bolts. Due to the "double-beam" structural feature in modular high-rise steel structures, the stiffened corrugated steel plate walls arranged in each floor of the structure exhibit discontinuous vertical force transmission. By combining the modular double beams into a single composite beam using high-strength bolts, the stacked lateral force resisting module units can form a vertically continuous lateral force resisting system, thereby achieving the same deformation mode and force transmission mechanism as traditional structures and significantly improving the seismic performance of modular high-rise steel structures.

[0037] like Figure 1(a)-Figure 1(c)As shown, the modular high-rise steel structure stiffened corrugated steel plate shear wall system of this utility model is formed by vertically stacking lateral force resisting module units 8, and then connecting the module units with columns and beams. This system can improve the lateral force resisting capacity of pure modular steel structures, increase the applicable height of modular steel structures in high-intensity fortification areas, and thus improve the safety and economy of modular steel structures.

[0038] like Figure 2(a)-Figure 2(b) As shown, the ordinary frame module unit 7 consists of module beams 3, module columns 4, and an outer cylinder 9. The module beams and columns are connected to the outer cylinder by welds to form the module unit. The lateral force resisting module unit 8 is formed by introducing stiffened corrugated steel plate walls into the ordinary frame module unit 7. The stiffened corrugated steel plate walls are reliably connected to the module beams and columns by welds.

[0039] like Figure 3(a)-Figure 2(b) As shown, the stiffened corrugated steel plate wall proposed in this utility model is mainly composed of corrugated steel plate 1 and stiffening ribs 2. Depending on the direction of the corrugations, it can be divided into two types: vertically stiffened corrugated steel plate wall and horizontally stiffened corrugated steel plate wall. Two pairs of stiffening ribs are arranged, evenly distributed on both sides of the corrugated steel plate and welded together with it. When the width-to-height ratio of the wall panel is large, a horizontally stiffened corrugated steel plate wall should be preferred.

[0040] like Figure 4 As shown, before the upper lateral force resisting module unit is installed, the connector 10 is inserted into the outer cylinder 9 of the lower lateral force resisting module unit. After stacking, grouting is carried out through the reserved grouting hole 12 to form the column-column grouting connection node 5. In order to form an effective lateral force resisting system, beam-beam bolt connection 6 must be carried out, that is, the module beam connected to the stiffened corrugated steel plate wall is connected by high-strength bolts.

[0041] Figure 5 The diagram shows the stacking of ordinary frame module units 7. Unlike the stacking of lateral force resisting module units 8, ordinary module units only require column-to-column grouting connections, without the need for beam-to-beam bolt connections.

[0042] Figure 6 This is a schematic diagram showing the connection between the ordinary frame module unit 7 and the lateral force resisting module unit 8. The connector 10 is welded onto the same horizontal connecting plate 13, thereby achieving the purpose of horizontal and vertical connection between the two module units. As for the four-module stack inside the structure, it also requires the use of a horizontal connecting plate to achieve horizontal and vertical connection between the modules.

[0043] This utility model is not limited to the embodiments described above. The above description of specific embodiments is intended to illustrate and explain the technical solution of this utility model. The specific embodiments described above are merely illustrative and not restrictive. Without departing from the spirit and scope of protection of this utility model and the claims, those skilled in the art can make many specific modifications based on the teachings of this utility model, and these modifications all fall within the protection scope of this utility model.
