[0002] A room-within-a-room structure refers to an architectural form in which an inner enclosure is set inside an outer enclosure, thus creating a "room within a room" layout. It is typically used in situations where high requirements for vibration control, sound insulation, and heat insulation are needed, such as laboratories, recording studios, and rooms for precision equipment.
[0003] Currently, room-within-a-room structures focus on achieving routine vibration control of building structures, such as addressing vibrations caused by external wind loads, equipment operation, or personnel activities during daily use. However, in situations with complex structural systems and high requirements for earthquake resistance, such as nuclear power plant control rooms, room-within-a-room structures are difficult to apply. In particular, earthquakes can easily cause relative displacement between the inner and outer envelope structures, leading to damage to pipes and equipment passing through the inner and outer envelope structures, which hinders their widespread application.

[0027] Reference will now be made in detail to various embodiments of this application, examples of which are shown in the accompanying drawings and described below. Although this application will be described in conjunction with exemplary embodiments, it should be understood that this application is not intended to be limited to those exemplary embodiments. Rather, this application is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents, and other embodiments that may be included within the spirit and scope of this application as defined by the appended claims.
[0028] This application uses specific terms to describe embodiments of the application. For example, "an embodiment" and / or "one embodiment" refers to a particular feature, structure, or characteristic associated with at least one embodiment of the application. Therefore, it should be emphasized and noted that "an embodiment" or "one embodiment" mentioned twice or more in different locations in this application does not necessarily refer to the same embodiment. Furthermore, certain features, structures, or characteristics in one or more embodiments of the application can be appropriately combined.
[0029] In this application, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying positional relationships or order of importance.
[0030] In the following description, the orientation or positional relationship indicated by terms such as "upper," "lower," "inner," "outer," "front," "back," or other directional terms is based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the structure or component referred to must have a specific orientation, be constructed in a specific orientation, and / or be implemented, and therefore should not be construed as a limitation of this application.
[0031] In the following description, unless otherwise expressly specified or limited, the terms "installation," "connection," "linking," "fixing," "contact," etc., should be interpreted broadly; for example, they can refer to a connection or an active connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of these terms in the embodiments of this application according to the specific circumstances.
[0032] It is understood that the room-within-a-room structure and its construction method provided in this application are particularly suitable for nuclear power plant control rooms, and can also be applied to other occasions that require the use of room-within-a-room structures and are suitable for the room-within-a-room structure provided in this application, such as laboratories, recording studios, precision equipment rooms, etc., without limitation.
[0033] In this application, the term "vertical" refers to the direction between the top and bottom of a room-within-a-room structure, such as... Figure 1 The Z-direction is shown. The term "lateral" refers to a direction perpendicular to the vertical direction, such as... Figure 1The X-direction is shown. Generally, the vertical direction of a room-within-a-room structure is roughly parallel to the direction of gravity, and the horizontal direction is roughly horizontal.
[0034] See Figure 1 The room-within-a-room structure 1 shown includes an outer enclosure structure 10, an inner enclosure structure 20, a support structure 30, and a displacement constraint structure 40.
[0035] The outer enclosure structure 10 includes an outer bottom plate 11, an outer wall 12, and an outer top plate 13, which together form a first space 14.
[0036] The inner enclosure structure 20 is located within the first space 14 and includes an inner floor slab 21, inner walls 22, and an inner roof slab 23. The inner floor slab 21, inner walls 22, and inner roof slab 23 together enclose the second space 24. The outer walls 12 and inner walls 22 are separated, and the outer roof slab 13 and inner roof slab 23 are separated, thus forming a hollow isolation layer, which is beneficial for achieving conventional vibration control as well as sound insulation and heat insulation effects.
[0037] The supporting structure 30 has one side connected to multiple spaced connection points on the outer base plate 11, and the opposite side connected to multiple spaced connection points on the inner base plate 21. It can support the vertical static load of the inner enclosure structure 20, and the supporting structure 30 is equipped with a damping structure. It should be noted that the damping structure (or energy-dissipating damping structure) described here differs from general earthquake-resistant structures that rely on the strength, stiffness, and ductility of the building structure (such as beams, columns, and walls) itself to resist earthquakes. Instead, it specifically refers to a structure equipped with energy-dissipating devices such as dampers, which absorb and dissipate the seismic energy transmitted into the room-within-a-room structure 1 to achieve damping.
[0038] The displacement restraint structure 40 is connected to both the outer enclosure structure 10 and the inner enclosure structure 20, and is used to provide forces to suppress relative displacement when the outer enclosure structure 10 and the inner enclosure structure 20 are displaced by seismic action. Generally, the displacement restraint structure 40 includes at least a first part connected to the outer enclosure structure 10 and a second part connected to the inner enclosure structure 20, and the first and second parts are movably connected to allow a certain degree of phase displacement between the inner and outer enclosure structures.
[0039] The room-within-a-room structure 1 provided in this application can achieve the beneficial effect of dual vibration and seismic control, that is, it has both conventional vibration control and seismic response control capabilities. The supporting structure 30 is connected to the outer floor slab 11 and the inner floor slab 21 only at multiple spaced connection points to reduce the contact area between the supporting structure 30 and the outer floor slab 11 and the inner floor slab 21, which helps to reduce the transmission of vibration energy from the outer enclosure structure 10 to the inner enclosure structure 20, as well as provide sound insulation and heat insulation. A damping structure is installed in the supporting structure 30 to dissipate seismic energy, and the inner and outer enclosure structures are connected by a displacement constraint structure 40 to suppress the relative displacement of the inner and outer enclosure structures caused by seismic action. This helps to improve the seismic response control capability of the room-within-a-room structure 1 and reduce the risk of damage to penetrating components such as pipes and electrical equipment caused by the relative displacement of the inner and outer enclosure structures during an earthquake.
[0040] like Figure 1 , Figure 3 As shown, in some embodiments, the support structure 30 includes a plurality of spaced-apart elastic supports 31. Each elastic support 31 includes a first connector 311, a second connector 312, and a spring damper 313. The first connector 311 connects to the outer base plate 11, the second connector 312 connects to the inner base plate 21, and the opposite ends of the spring damper 313 are connected to the first connector 311 and the second connector 312, respectively. The spring damper described here refers to a device that combines elasticity and damping characteristics. The elastic supports 31 support the inner enclosure structure 20, and the spring dampers 313 also serve as a shock-absorbing structure, buffering and primarily resisting vertical seismic forces during earthquakes. The damping structure also includes at least two connecting rods 321, each equipped with a damper 322. One end of each connecting rod 321 is hinged to the same hinged support 323 on the inner base plate 21, while the other ends are respectively hinged to hinged supports 323 on the first connecting members 311 of different elastic supports 31. Thus, the two connecting rods 321 are approximately inverted "V" shapes. This inverted "V" shape design provides good overall mechanical performance and accurately captures the relative displacement of the inner and outer enclosure structures, causing the dampers to displace and dissipating seismic energy. When an earthquake causes relative displacement of the inner and outer enclosure structures, the connecting rods 321 rotate and expand / contract around the hinged supports 323, causing the dampers 322 to dissipate energy, which is particularly beneficial for resisting lateral seismic forces.
[0041] like Figure 4As shown, in some embodiments, the support structure 30 includes a plurality of spaced elastic supports 31 as described above, which will not be repeated here. The support structure 30 also includes a plurality of spaced seismic isolation supports 33, with their opposite ends connected to the outer base plate 11 and the inner base plate 21, respectively. The seismic isolation support 33 refers to a support device designed to achieve seismic isolation, characterized by relatively high vertical stiffness and relatively low lateral stiffness, providing a flexible connection effect that can deform laterally under seismic loading. The seismic isolation support 33 can be configured as a rubber-type seismic isolation support containing rubber material, which is common in the art, or as a sliding-type seismic isolation support that achieves seismic isolation using the principle of sliding friction, etc., without limitation. The design using the seismic isolation support 33 is beneficial for vertically supporting the inner enclosure structure 20 and can reduce the impact of horizontal seismic loading on the inner enclosure structure 20.
[0042] like Figure 3 As shown, the elastic support 31 can be further configured such that: the first connecting member 311 has a first cavity 3111, and the second connecting member 312 has a second cavity 3121. The first cavity 3111 and the second cavity 3121 together constitute a receiving space for accommodating the spring damper 313, which helps to limit the position of the spring damper 313. The first connecting member 311 is vertically movably connected to the second connecting member 312, and the first connecting member 311 is provided with a limiting block 312, and the second connecting member 312 is provided with a limiting groove 3122. The limiting block 312 and the limiting groove 3122 cooperate, which helps to guide the spring damper 313 to move vertically and limit the relative vertical movement range of the first connecting member 311 and the second connecting member 312, thereby improving the stability and safety of the room-within-a-room structure 1.
[0043] like Figure 5 , Figure 6 As shown, in some embodiments, the displacement constraint structure 40 includes a third connector 41, a fourth connector 42, a first plate 43, a second plate 44, a third plate 45, a first bolt 46, and a second bolt 47. The first plate 43, the second plate 44, and the third plate 45 can all be made of steel plates. The third connector 41 is fixedly connected to the outer enclosure structure 10; the fourth connector 42 is fixedly connected to the inner enclosure structure 20; the first plate 43 and the second plate 44 are connected to the third connector 41; the third plate 45 is disposed between the first plate 43 and the second plate 44, and contacts the first plate 43 and the second plate 44, and is connected to the fourth connector 42; the first bolt 46 passes through the first plate 43 and the second plate 44, providing preload to ensure a tight connection between the first plate 43 and the second plate 44, preventing the displacement constraint structure 40 from failing. Multiple first bolts 46 can be provided, for example... Figure 6The first bolt 46 shown is provided as six. The third plate 45 has a slotted hole 48. The second bolt 47 passes through the first plate 43, the second plate 44, and the slotted hole 48 in the third plate 45. Thus, when the third plate 45 is displaced relative to the first and second plates, the second bolt 47 can move within the slotted hole 48. The second bolt 47 provides a preload to ensure that the first plate 43 and the second plate 44 clamp the third plate 45, generating friction at the contact surface. The first and second plates may also have slotted holes corresponding to the slotted holes 48, allowing the second bolt to pass through; this is not a limitation. When the external vibration excitation is small (such as in normal use), the relative displacement of the inner and outer enclosure structures is within the allowable range or negligible. At this time, the third plate 45 basically does not slide relative to the first plate 43 and the second plate 44. When the external vibration excitation exceeds the threshold (such as when an earthquake occurs), the relative displacement of the inner and outer enclosure structures exceeds the allowable range. Then the third plate 45 slides relative to the first plate 43 and the second plate 44. The contact surface provides friction to suppress the excessive relative displacement of the inner and outer enclosure structures and dissipate energy, which is beneficial to protect devices that pass through the inner and outer enclosure structures, such as pipes and cables.
[0044] like Figure 7 , Figure 8 As shown, in some embodiments, the displacement constraint structure 40 includes a third connector 41, a fourth connector 42, and an elastic member 49; the third connector 41 is connected to the outer enclosure structure 10; the fourth connector 42 is connected to the inner enclosure structure 20; the opposite ends of the elastic member 49 are respectively connected to the third connector 41 and the fourth connector 42. When an earthquake occurs, the inner and outer enclosure structures are displaced relative to each other, and the elastic member 49 expands and contracts and accumulates elastic potential energy, providing elastic force to suppress excessive relative displacement between the inner and outer enclosure structures, which is beneficial for protecting devices that pass through the inner and outer enclosure structures, such as pipes and cables.
[0045] like Figure 1 , Figure 5 , Figure 7 As shown, specifically, the third connector 41 is connected to the outer wall 12 of the outer enclosure structure 10; the fourth connector 42 has a first connecting portion 421 and a second connecting portion 422 bent relative to the first connecting portion 421. The first connecting portion 421 is connected to the third plate 45, and the second connecting portion 422 is connected to the inner top plate 23 of the inner enclosure structure 20. Both the third connector 41 and the fourth connector 42 can be plates, wherein the fourth connector 42 is an L-shaped plate with a generally "L"-shaped cross-section to provide the first connecting portion 421 and the second connecting portion 422. The first plate 43, the second plate 44, and the third plate 45 are distributed vertically, so that the third plate 45 can slide approximately laterally relative to the first plate 43 and the second plate 44 to provide friction, and / or the elastic member 49 can provide approximately lateral elastic force. This helps to suppress the lateral relative displacement of the inner and outer enclosure structures.
[0046] like Figure 2 As shown, in some embodiments, the outer base plate 11 (vertically) is sequentially laid with a vibration-damping and sound-insulating layer 111, a steel plate layer 112, a waterproof layer 113, and a concrete layer 114 from bottom to top. The vibration-damping and sound-insulating layer 111 includes a plurality of spaced vibration-damping pads 1112 and glass wool 1111 placed between the plurality of vibration-damping pads. The vibration-damping pads 1112 are pads made mainly of polymer materials such as polyurethane and rubber, which can effectively reduce vibration and noise. Sound insulation boards 115 are provided between the vibration-damping and sound-insulating layer 111 and the outer wall 12, and between the steel plate layer 112 and the outer wall 12. The sound insulation board 115 is a board with an average sound insulation of more than 30dB. The waterproof layer 113 covers the sound insulation board 115. A sealing structure 116, such as sealant or prefabricated sealing strips, sealing tapes, etc., is provided at the contact position between the concrete layer 114 and the outer wall 12. The supporting structure 30 is set on the concrete layer 114. This design helps to improve the vibration reduction and sound insulation capabilities of the room-within-a-room structure 1.
[0047] Specifically, the vibration damping and sound insulation layer 111 can be set to a thickness in the range of 45mm to 65mm, such as rubber vibration damping pads 1112 of about 50mm×50mm×50mm, glass wool 1111 of about 50mm thickness, the steel plate layer 112 can include multiple layers of steel plates, such as two layers of steel plates with a single layer thickness of about 4mm, and the waterproof layer 113 can be polymer modified bitumen root-penetration resistant waterproof membrane of about 2mm thickness, etc., without being limited to these.
[0048] In some embodiments, the room-within-a-room structure 1 is used for the control room of a nuclear power plant. The control room also includes devices such as pipes and cables that pass through the outer enclosure structure 10 and the inner enclosure structure 20. During the operation of a nuclear power plant unit, conventional vibration excitations, such as vibrations from pipes and equipment operation, can easily be transmitted to the nuclear power plant control room through floors, walls, and penetrations, resulting in significant noise within the control room and affecting the working comfort of the operators. The room-within-a-room structure 1 facilitates vibration control and noise reduction in the nuclear power plant control room, meets seismic response control requirements, and reduces the risk of damage to pipes, cables, and other devices passing through the inner and outer enclosure structures during earthquakes.
[0049] This application also provides a construction method for constructing a room-within-a-room structure 1, which includes: Glass wool 1111 is laid on the outer bottom plate 11 of the outer enclosure structure 10, and then spaced vibration damping pads 1112 are installed to provide a vibration damping and sound insulation layer 111. Then, a steel plate layer 112 and a waterproof layer 113 are laid sequentially on the vibration damping and sound insulation layer 111. Finally, concrete is poured to provide a concrete layer 114. This method is beneficial to improving the vibration damping and sound insulation capabilities of the room-within-a-room structure 1.
[0050] In summary, the beneficial technical effects of this application include, but are not limited to, at least one of the following: The room-within-a-room structure provided in this application achieves the beneficial effect of dual vibration and seismic control, meaning it possesses both conventional vibration control and seismic response control capabilities. The room-within-a-room structure design separates the outer and inner walls, as well as the outer and inner roof slabs, forming hollow isolation layers. The supporting structure is connected to the outer and inner floor slabs only through multiple spaced connection points to reduce contact, which helps reduce the transmission of vibration energy from the outer envelope to the inner envelope, and provides sound and heat insulation. A damping structure is incorporated into the supporting structure to dissipate seismic energy, and a displacement constraint structure connects the inner and outer envelopes to suppress relative displacement caused by seismic action. This enhances the seismic response control capability of the room-within-a-room structure and reduces the risk of damage to pipes, cables, and other equipment due to relative displacement of the inner and outer envelopes during an earthquake.
