Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and specifically to a seismic isolation structure with flush inner and outer walls. Background Technology

[0002] In seismic design of buildings, seismic isolation joints are a key measure to mitigate collision damage between adjacent structural units under seismic loads.

[0003] Traditional seismic isolation joint construction, especially its external wall cover plate, usually uses a metal cover plate directly covering the joint opening with a height difference between it and the walls on both sides. This approach has a prominent problem: during an earthquake, the connection between the cover plate and the wall is rigid or only partially flexible, which cannot effectively adapt to large dynamic changes in the joint width. This often leads to the cover plate being squeezed and deformed, the seal failing, and it cannot automatically reset after the earthquake, seriously affecting the building's aesthetics, waterproofing, and subsequent usability.

[0004] Therefore, there is an urgent need for a seismic isolation joint structure that can coordinate deformation during earthquakes, automatically reset after earthquakes, and not affect the flatness and aesthetics of the interior and exterior walls of buildings. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art and provide a seismic isolation structure with flush inner and outer walls. This structure achieves dynamic flush sealing between the decorative cover plate and the wall, coordinated adaptation to large earthquake displacements, and automatic reset after the earthquake through a unique cross-joint connection and elastic compression sealing mechanism.

[0006] To achieve the above objectives, the present invention provides a seismic isolation structure with flush inner and outer walls, disposed at the seismic isolation joint between two adjacent building units, the seismic isolation structure comprising: The external wall flush sealing unit is installed on the outside of the seismic isolation joint; The inner wall flush sealing unit is installed on the inner side of the seismic isolation joint; Both the external wall flush sealing unit and the internal wall flush sealing unit include: A decorative cover plate, which is normally pressed against the building wall on the side where it is located, and whose exterior surface is normally flush with the building wall surface on the side where it is located. A cross-seismic joint expansion connection mechanism includes a sliding rod that can be extended at both ends, with the two ends of the sliding rod respectively hinged to the corresponding building units on both sides of the seismic isolation joint; An elastic compression sealing mechanism is connected between the decorative cover plate and the slide rod of the cross-joint telescopic connection mechanism. It is used to provide an elastic compression force to the decorative cover plate pointing towards the wall, and to provide a tendency for the decorative cover plate to return to its original position after it slides due to wall displacement.

[0007] By adopting this technical solution, through the synergy of the cross-joint expansion connection mechanism and the elastic compression sealing mechanism, dynamic flush sealing between the decorative cover plate and the wall surface, coordinated adaptation to large displacements during earthquakes, and automatic reset after earthquakes are achieved. This fundamentally solves the technical problems of traditional decorative cover plates being unable to adapt to large displacements and unable to automatically reset, while ensuring the flushness between the decorative cover plate and the wall surface, thus balancing earthquake resistance and architectural aesthetics.

[0008] Furthermore, the seismic isolation structure also includes a flexible buffer wall, which fills the seismic isolation joint and is located between the outer wall flush sealing unit and the inner wall flush sealing unit. The flexible buffer wall includes a keel frame, flexible thermal insulation material filled in the keel frame, and composite panels fixed to both sides of the keel frame. The keel frame is not rigidly connected to the walls of the adjacent building units.

[0009] By adopting this technical solution, the flexible buffer wall not only provides conventional thermal insulation and fireproof functions, but its key role is to provide an internal, flexible buffer and energy dissipation layer for the entire system during an earthquake. It can effectively absorb and dissipate seismic energy, significantly reduce the impact force transmitted to the cladding and connecting mechanisms, and improve the overall durability and reliability of the structure.

[0010] Furthermore, the flexible insulation material is rock wool; The composite panel is a calcium silicate reinforced board.

[0011] By adopting this technical solution, rock wool provides excellent elastic cushioning and fireproof thermal insulation performance; while reinforced calcium silicate board provides a high-strength, fireproof and flat wall base, ensuring the overall performance of the cushioning wall.

[0012] Furthermore, a waterproof strip is provided between the decorative cover and the flexible buffer wall.

[0013] By adopting this technical solution, a reliable dynamic waterproof structure is added to both the exterior and interior walls. Even when an earthquake causes the cover plate to slide and the joints to deform, it can effectively prevent rainwater from seeping into the interior of the wall, thus solving the leakage problem of the seismic isolation joint.

[0014] Furthermore, the elastic compression sealing mechanism includes: A connecting base is fixed to the back of the decorative cover plate; An adjusting bolt is inserted through the slide bar of the cross-slit telescopic connection mechanism, with one end fixedly connected to the connecting base and the other end threaded with a locking nut. An elastic element is sleeved on the adjusting bolt, with its two ends acting on the slide rod of the cross-slit telescopic connection mechanism and the locking nut, respectively.

[0015] By adopting this technical solution, the structure including the adjusting bolts allows for precise adjustment and locking of the preload of the elastic element. This enables flexible setting of the clamping force of the veneer cover during construction and maintenance, ensuring that the sealing effect is always at its best, and enhancing the engineering applicability and maintainability of the structure.

[0016] Furthermore, the connecting base is an aluminum alloy base; The elastic element is a helical spring, and it is normally in a compressed state.

[0017] By adopting this technical solution, the connecting base is limited to an aluminum alloy base (lightweight and high strength), and the elastic element is a compressed helical spring. This clarifies the specific, reliable, and mature component selection for achieving the elastic clamping and reset functions, and ensures long-term corrosion resistance and operational stability.

[0018] Furthermore, flexible fireproof sealing material is filled between the decorative cover plate of the exterior wall flush sealing unit and the exterior wall of the building, and between the decorative cover plate of the interior wall flush sealing unit and the interior wall of the building.

[0019] By adopting this technical solution, a flexible fireproof sealing material is filled between the decorative cover plate and the building wall, forming the most direct first line of sealing and fire protection barrier. Its flexibility ensures that it will not crack brittlely during earthquake deformation and continues to play a sealing role. In conjunction with the elastic compression mechanism, it achieves a long-lasting seal for dynamic joints.

[0020] Compared with the prior art, the present invention has the following advantages: 1. By using independent flush sealing units for both inner and outer walls, and utilizing their internal elastic compression sealing mechanism, the decorative cover plate is tightly pressed against the wall surface under normal conditions, achieving a seamless flush connection with the inner and outer wall decorative surfaces and completely eliminating the protrusion of traditional cover plates. At the same time, this elastic compression sealing mechanism can continuously provide adaptive compression force during wall displacement caused by earthquakes, ensuring the reliability of the seal under dynamic deformation, and effectively solving the problems of sealant tearing and rainwater leakage caused by displacement in traditional structures.

[0021] 2. An innovative cross-joint telescopic connection mechanism is adopted. Its hinged ends and telescopic rod design can effectively absorb and adapt to the complex deformation of the seismic isolation joint in three directions during an earthquake. After the earthquake, the energy stored in the elastic compression sealing mechanism drives the decorative cover plate to automatically and accurately return to the initial flush position, restoring the integrity and aesthetics of the structure and significantly reducing maintenance costs.

[0022] 3. The flexible buffer wall is not rigidly connected to the building structure on both sides. During an earthquake, the flexible material inside the wall can preferentially undergo compression deformation to dissipate energy, providing valuable buffer space for the flush sealing unit inside and outside. This greatly reduces the impact risk of structural collisions on the core seismic isolation and sealing device, and improves the durability of the entire system.

[0023] 4. By organically combining reinforced calcium silicate board composite wall, fireproof sealing materials, waterproof strips and other structures, the core seismic isolation and repositioning functions are achieved, while fully meeting the building's requirements for thermal insulation, fireproofing and waterproofing. This forms a fully functional and reliable integrated seismic isolation joint structure, which is especially suitable for high-standard large public buildings. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] This invention provides a seismic isolation structure with flush inner and outer walls, which is integrally set at the seismic isolation joint between two adjacent original building walls (building unit 8). The width of the seismic isolation joint can be set according to the seismic design requirements, for example, 50mm to 200mm. The structure mainly consists of three parts: an outer wall flush sealing unit 2 located on the outer side, an inner wall flush sealing unit 3 located on the inner side, and a flexible buffer wall 4 filling the space between the two. At the corresponding position of the ground seismic isolation joint, a composite cover plate 5 that matches the bottom end of the flexible buffer wall 4 is also laid. The specific structures of the exterior wall flush sealing unit 2 and the interior wall flush sealing unit 3 are as follows: The exterior wall flush sealing unit 2 and the interior wall flush sealing unit 3 are symmetrical and independent in terms of construction principle, and both realize the functions of flushing, sealing, sliding and resetting. For clarity, the following description uses the two units as examples, and their structures can be interchanged or adapted to their respective wall finishes.

[0028] 1. Detailed structure of exterior wall flush sealing unit 2 (e.g.) Figure 2 (as shown) This unit mainly includes an exterior wall cladding cover plate 11, a cross-joint expansion and contraction connection mechanism, and an elastic compression sealing mechanism; among which... The exterior wall cladding cover 11 is made of metal, and its outer surface cladding is consistent with that of the adjacent original exterior wall cladding panel 6. Under normal conditions, its outer surface is flush with the outer surface of the original exterior wall cladding panel 6.

[0029] The cross-joint expansion joint mechanism includes an external wall sliding rod 13 that can be extended at both ends. The external wall sliding rod 13 can be a sleeve-type sliding rod or other structures. Its two ends are hinged to the original building walls (building units 8) on both sides of the seismic isolation joint through hinged supports. This connection method with hinged ends allows the external wall sliding rod 13 to have a certain degree of rotational freedom in three-dimensional space to adapt to complex spatial displacement during earthquakes.

[0030] The elastic compression sealing mechanism is connected between the exterior wall cladding cover plate 11 and the exterior wall sliding rod 13, and specifically includes: The exterior wall connection base 12 is an aluminum alloy base that is firmly fixed to the back side of the decorative cover plate 11 by fasteners.

[0031] The adjusting bolt passes through the pre-set through hole or mounting base on the external wall sliding rod 13. One end of the adjusting bolt is fixedly connected to the external wall connecting base 12, and the other end is fitted with a locking nut.

[0032] The external wall elastic element 15 is a helical spring, which is sleeved on the aforementioned adjusting bolt. One end of the spring acts on the external wall sliding rod 13, and the other end acts on the locking nut end of the adjusting bolt. By rotating the locking nut, the initial compression of the spring can be precisely adjusted, thereby setting the initial clamping force of the external wall cladding cover 11 on the wall surface.

[0033] Under normal conditions, the spring is in a compressed state. By adjusting the bolts and the external wall connection base 12, a pressure is continuously applied to the external wall cladding cover plate 11 pointing towards the original external wall decorative integrated panel 6, so that it fits tightly against the wall surface. At the same time, a flexible fireproof sealing material 10 (such as fireproof sealant) is filled between the external wall cladding cover plate 11 and the wall surface to further enhance the sealing effect.

[0034] It should be noted that, in order to make the surface of the exterior wall cladding cover plate 11 flush with the surface of the original exterior wall decorative integrated panel 6, the original building walls (building unit 8) on both sides of the seismic isolation joint are obviously provided with relief grooves to allow the ends of the exterior wall cladding cover plate 11 to make way; and in order to allow the exterior wall cladding cover plate 11 to adapt to the position change when the original building wall is moved, the inner sides of its two ends are set as curved surfaces, and the curved surface transition avoids the rigid collision between the exterior wall cladding cover plate 11 and the original building wall (building unit 8) and cause structural damage. 2. Detailed structure of the interior wall flush sealing unit 3 (e.g.) Figure 3 (as shown) This unit corresponds to the structure of the external wall flush sealing unit 2, and mainly includes the internal wall cladding cover plate 16, the cross-joint expansion connection mechanism, and the elastic compression sealing mechanism.

[0035] Interior wall finish cover plate 16: can be a metal cover plate, the inner surface of which is covered with a resin board finish layer that is consistent with the material and effect of the adjacent interior wall resin board finish plate 7, so that it is completely flush with the interior wall finish under normal conditions.

[0036] Expansion joint connection mechanism: including inner wall sliding rod 17, both ends of which are also connected to the building structure on both sides in a hinged manner.

[0037] The elastic compression sealing mechanism includes an inner wall connecting base 18 (aluminum alloy base) fixed to the back of the inner wall cladding cover plate 16, an adjusting bolt passing through the inner wall sliding rod 17, and an inner wall elastic element 20 (coil spring) sleeved on the bolt. Its working principle is exactly the same as that of the outer wall flush sealing unit 2. By adjusting the nut to set the pre-compression force of the spring, the inner wall cladding cover plate 16 is pressed against the inner wall surface, and the gap is filled with flexible fireproof sealing material 10.

[0038] It should be noted that, in order to achieve flushness between the surface of the interior wall cladding cover plate 16 and the surface of the original interior wall resin board cladding plate 7, the original building walls (building unit 8) on both sides of the seismic isolation joint are obviously provided with relief grooves to allow for the end of the interior wall cladding cover plate 16 to make way; and in order to allow the interior wall cladding cover plate 16 to adapt to the positional change when the original building wall is moved, its inner sides at both ends are made into curved surfaces. At the same time, the curved transition avoids the rigid collision between the interior wall cladding cover plate 16 and the original building wall (building unit 8) and cause structural damage. 3. The specific structure of the flexible buffer wall 4 (e.g.) Figure 4 (as shown) Flexible buffer wall 4 is filled in the seismic isolation joint, forming the building's internal thermal insulation, fireproofing, and sound insulation walls, and also serving as the main energy-absorbing buffer; it includes: Keel frame: It consists of vertically arranged C-shaped keel 21 and top and bottom keels 23 fixed to the upper and lower structural surfaces of the building.

[0039] Flexible insulation material 24: preferably fireproof and heat-insulating rock wool, densely filling the cavity enclosed by the keel frame and the side panels.

[0040] Composite panel 22: It is a reinforced calcium silicate board, which is fixed to both sides of the C-shaped keel 21 by fasteners such as self-tapping screws to form two surfaces of the wall.

[0041] The key is that the keel frame is not rigidly connected to the original building walls (building unit 8) on both sides, but is in flexible contact with them through the filling flexible insulation material 24. This reserves valuable buffer space. When an earthquake causes the walls on both sides to move towards each other, the flexible insulation material 24 is squeezed first, and its elastic deformation is used to absorb energy, thereby protecting the outer wall cladding 11, inner wall cladding 16 and composite panel 22 on both sides from rigid impact. 4. Other related structures: Waterproof tape 14: such as Figure 2 As shown, in the external wall flush sealing unit 2, a rubber waterstop is installed between the inner edge of the external wall cladding cover plate 11 and the composite panel 22 of the flexible buffer wall 4 as an additional waterproof barrier.

[0042] It should be noted that the waterproofing strip 14 can exist simultaneously between the interior wall flush sealing unit 3 and the flexible buffer wall 4 to further improve the waterproofing effect.

[0043] Fasteners: such as self-tapping screws 19, used to fix components such as the inner wall connection base 18 to the building structure.

[0044] Original building column 9 and light steel keel double-layer paper-faced fireproof gypsum board 1: The original building column 9 is connected to the inside of any original building wall (building unit 8) to accommodate the presence of the seismic isolation joint at that location. In this case, it is necessary to install the opposite light steel keel double-layer paper-faced fireproof gypsum board 1 on another original building wall (building unit 8). Then, the two ends of the inner wall flush sealing unit 3 are connected to the original building column 9 and the light steel keel double-layer paper-faced fireproof gypsum board 1 respectively. In addition to achieving flushness between the inner and outer sides, it also increases the distance between the inner wall flush sealing unit 3 and the outer wall flush sealing unit, making the entire seismic isolation structure easier to achieve. The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
