Detailed Implementation

[0031] This invention proposes a building module unit and modular building structure, addressing the common problem of insufficient lateral resistance in existing modular buildings, which fails to meet the wind and earthquake resistance requirements of large-span, high-rise buildings. The invention incorporates damping node components at the eight vertices of the building module unit's frame and supporting components within the frame. Both the damping node components and the supporting components are energy-dissipating and vibration-damping elements. The damping node components feature independent control over load-bearing capacity and stiffness, and controllable plastic development. The supporting components effectively reduce the axial force at the column ends under strong earthquakes. Compared to existing technologies, the synergistic effect of the damping node components and supporting components effectively improves the stiffness, load-bearing capacity, and energy dissipation capacity of the building module unit, reduces beam and column damage under earthquakes, and accelerates post-earthquake performance recovery.

[0032] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0033] Example 1:

[0034] Reference Figure 1 and Figure 2 This embodiment provides a building module unit, including a frame body 1 and a support assembly 2. The frame body 1 is cubic in shape and includes beams 11, columns 12, and damping node assemblies 3. The beams 11 form the horizontal sides of the cube, and the columns 12 form the vertical sides of the cube. The beams 11 and columns 12 are directly connected or connected through the damping node assemblies 3. At least one damping node assembly 3 is provided at each of the eight vertices of the frame body 1 at the connection between the beams 11 and the columns 12. The damping node assembly 3 can undergo plastic deformation under stress to ensure bending energy dissipation at the corresponding beam 11 end.

[0035] Furthermore, at least one set of support components 2 is installed within a frame consisting of beams 11 and columns 12 within the frame body 1. Support components 2 are installed within at least two opposing frames, meaning they are symmetrically arranged within two or four opposing frames to ensure a symmetrical distribution of the overall support function of the frame body 1 and improve stability. The two ends of the support components 2 are respectively located at the two ends of the frame along the vertical direction, facilitating the absorption of vertical forces on the frame. The support components 2 are capable of plastic deformation under stress, effectively reducing the horizontal axial force at the end of column 12 under strong earthquakes.

[0036] The synergistic effect of support component 2 and damping node component 3 can effectively improve the stiffness, load-bearing capacity and energy dissipation capacity of building module units, reduce the damage to beams 11 and columns 12 in the frame body 1 under seismic action, and accelerate the post-earthquake performance recovery of modular structures.

[0037] Among them, the setting rule of beams 11 and columns 12 in the frame body 1 is "strong column weak beam", that is, beams 11 are thinner than columns 12. At the same time, the beams 11 located at the top are thinner than the beams 11 located at the bottom, so as to ensure that the building module unit has sufficient load-bearing capacity.

[0038] Reference Figure 4 and Figure 5 This embodiment provides a building module unit. The support component 2 includes an outer cylinder 21, an inner cylinder 22, a first force-bearing part 23, and a second force-bearing part 24. The inner cylinder 22 has a U-shaped cross-section and is slidably disposed inside the first end of the outer cylinder 21. The opening of the inner cylinder 22 faces the same direction as the opening of the first end of the outer cylinder 21, facilitating the sliding of the inner cylinder 22 relative to the outer cylinder 21, and particularly facilitating the extension of the opening end of the inner cylinder 22 beyond the first end of the outer cylinder 21. The opening end of the inner cylinder 22 is connected to the frame body 1, and when the frame body 1 is subjected to force, the force can be transmitted to the inner cylinder 22. Multiple partitions 211 provided on the outer cylinder 21 provide constraint and fixed attachment for the inner cylinder 22 and the second force-bearing part 24. Figure 4 and Figure 5 For the purposes of this demonstration, no further details are provided here. Additionally, to prevent the inner cylinder 22 from detaching from the outer cylinder 21 during sliding under pressure, a limiting block 212 is installed at the lower part of the inner side of the outer cylinder 21, forming a track for the inner cylinder 22 to slide.

[0039] The first force-bearing part 23 is disposed inside the inner cylinder 22, with one end fixed to the end of the inner cylinder 22 and the other end fixed to the end of the first end of the outer cylinder 21. The second force-bearing part 24 is fixedly disposed inside the second end of the outer cylinder 21, and the second force-bearing part 24 extends out of the end of the second end opening of the outer cylinder 21 and connects to the frame body 1.

[0040] Regarding the force-bearing process of the first force-bearing part 23 and the second force-bearing part 24, taking the first force-bearing part 23 as an example: When the end of the inner cylinder 22 connected to the frame body 1 is subjected to a tensile force from the frame body 1, since the first force-bearing part 23 is fixedly connected to the inner cylinder 22, the first force-bearing part 23 is subjected to the tensile force from the inner cylinder 22; then, the other end of the first force-bearing part 23 is fixedly connected to the outer cylinder 21, so the outer cylinder 21 is subjected to the tensile force from the first force-bearing part 23; at the same time, the outer cylinder 21 provides a tensile force to the second force-bearing part 24. The second force-bearing part 24 is connected to the frame body 1, and the second force-bearing part 24 is simultaneously subjected to two opposite forces from the outer cylinder 21 and the frame body 1, that is, it balances the tensile force from the frame body 1 on one end of the inner cylinder 22; when the force does not exceed the load of the support assembly 2, the support assembly 2 balances the force situation inside the frame body 1. The pressure or tension of the frame body 1 on the support component 2 comes from the force that drives the internal deformation of the frame body 1 when it is subjected to external force.

[0041] Reference Figure 4 , Figure 5 and Figure 6 This embodiment provides a building module unit. The first force-bearing part 23 and the second force-bearing part 24 have the same structure. Here, the first force-bearing part 23 is used as an example for description: The first force-bearing part 23 includes a core plate that passes through the inner cylinder 22. Two first strip-shaped through holes 2311 are arranged side by side at intervals on the core plate. The first strip-shaped through holes 2311 are arranged along the extension direction of the inner cylinder. The two first strip-shaped through holes 2311 divide the core plate into a constraint section 2312 and a buckling section 2313. The constraint section 2312 is located between the two first strip-shaped through holes 2311, and the two buckling sections 2313 are located on both sides of the constraint section 2312.

[0042] Among them, reference Figure 6 The two ends of the constraint segment 2312 are vertically welded with plates 232, which support the two ends of the constraint segment 2312 to enhance the stiffness of the constraint segment 2312 and prevent the constraint segment 2312 from buckling first, which would cause the first force-bearing part 23 to not be fully supported and dissipate energy.

[0043] Reference Figure 6This embodiment provides a building module unit. The first force-bearing part 23 further includes two reinforcing plates 233 and two reinforcing strips 234. The two reinforcing strips 234 are respectively placed in two first strip-shaped through holes 2311, and the thickness of the reinforcing strips 234 is greater than the depth of the first strip-shaped through holes 2311. The two reinforcing plates 233 are arranged opposite to each other on both sides of the core plate, and the two reinforcing plates 233 are respectively attached to the two reinforcing strips 234 on both sides of the core plate. Because the thickness of the reinforcing strips 234 is greater than the depth of the first strip-shaped through holes 2311, the two reinforcing plates 233 maintain a certain distance from the core plate when they are attached to the two reinforcing strips 234, that is, they are not fully attached to the core plate. The two reinforcing plates 233 are fixed by high-strength bolts, and the high-strength bolts pass through both the reinforcing strips 234 and the two reinforcing plates 233. The two reinforcing plates 233 further constrain the core plate. When the core plate is subjected to stress exceeding the buckling critical load, micro-amplitude multi-wave buckling of the constrained section 2312 of the core plate can be achieved. In this way, partial buckling of the core plate causes the support to degrade, which plays a good role in energy dissipation and avoids excessive support from damaging the frame body 1.

[0044] Reference Figure 4 and Figure 5 When the core plate is subjected to stress exceeding the buckling critical load and deforms, the inner cylinder 22 slides along the gap reserved at one end of the limiting block 212 and the outer cylinder 21.

[0045] Meanwhile, the first force-bearing part 23 and the second force-bearing part 24 are fixedly installed using high-strength bolts. When the first force-bearing part 23 and / or the second force-bearing part 24 are damaged by stress in environments such as earthquakes, only the damaged first force-bearing part 23 and / or the second force-bearing part 24 need to be replaced after the earthquake ends. It has the characteristics of easy assembly and easy replacement, which helps to save processing time and reduce economic costs.

[0046] Reference Figure 1 and Figure 2 This embodiment provides a building module unit, in which a set of support components 2 are set within a frame, and the support components 2 are set along the diagonal of the frame. Connectors 13 are pre-installed at the connection points between the frame and both ends of the support components 2. The connectors 13 can be I-shaped steel sections welded to the frame body 1, with bolt holes pre-drilled in their webs and flanges. The open end of the inner cylinder 22 and the end of the second force-bearing part 24 extending out of the second opening of the outer cylinder 21 are respectively connected to the connectors 13 by bolts. Furthermore, a cover plate (unmarked) is additionally provided in the area where the bolts are distributed on the connectors 13, and the bolts pass through the cover plate for fixed connection, increasing stability.

[0047] In addition, for ease of connection, the support assembly 2 is also provided with a connecting block 25. The connecting block 25 is located at the opening end of the inner cylinder 22, at the connection point between the second force-bearing part 24 and the connecting member 13. The connecting block 25 and the connecting member 13 are connected by bolts, and the opening end of the inner cylinder 22, the second force-bearing part 24 and the connecting block 25 are welded together.

[0048] Reference Figure 3 This embodiment provides a building module unit. Another form of support component 2 arrangement is to set two sets of support components 2 within a frame, with the two sets of support components 2 arranged end-to-end in a V-shape within the frame. The connection points of the two sets of support components 2 are connected to the beam 11, and the free ends of the two sets of support components 2 are connected to the connection points between the beam 11 and the column 12 of the frame. The support components 2 can also function well.

[0049] Reference Figure 1 , Figure 2 and Figure 7 This embodiment provides a building module unit where, at each vertex of the frame body 1, only one damping node assembly 3 is provided at the connection between a beam 11 and a column 12. The damping node assembly 3 is located at the end of the beam 11. Thus, the column 12 is a single, integrated structure in the vertical direction. The damping node assembly 3 at the connection between the beam 11 and the column 12 maximizes protection of the column 12 from damage by the beam 11 in the event of an earthquake or other earthquake. (Refer to...) Figure 7 The damping node assembly 3 includes a first hinge 31, a second hinge 32, a first fixing plate 33, and a second fixing plate 34. The first hinge 31 is fixedly connected to the column 12, and the second hinge 32 is fixedly connected to the beam 11. The first hinge 31 and the second hinge 32 are hinged together by a horizontally arranged pin 35 to form a hinge body. The first fixing plate 33 and the second fixing plate 34 are clamped and arranged on both sides of the hinge body along the horizontal direction. Both the first fixing plate 33 and the second fixing plate 34 are parallel to the plane enclosed by the frame on which they are located. The first fixing plate 33 and the second fixing plate 34 are respectively bolted to the first hinge 31 and the second hinge 32. During an earthquake, the first hinge 31 and the second hinge 32 bear the main axial force and shear force of the beam 11, preventing shear failure of the damping node assembly 3 and ensuring bending energy dissipation at the end of the beam 11.

[0050] Reference Figure 1 , Figure 2 and Figure 7This embodiment provides a building module unit. Both the first fixing plate 33 and the second fixing plate 34 are provided with multiple second strip-shaped through holes of unequal lengths. These second strip-shaped through holes are arranged horizontally, and their centers are located on the same straight line. The multiple second strip-shaped through holes 331 on the first fixing plate 33 are centrally symmetrically distributed from top to bottom with respect to the center of the first fixing plate 33; similarly, the multiple second strip-shaped through holes 341 on the second fixing plate 34 are centrally symmetrically distributed from top to bottom with respect to the center of the second fixing plate 34. This distribution of the second strip-shaped through holes reduces the load-bearing capacity of the damping node assembly 3, ensures consistent rotational stiffness of the fixing plates, facilitates deformation under high stress, and improves the energy dissipation capacity of the beam 11.
