Description

Technical Field

[0001] This utility model relates to the field of building seismic isolation technology, and in particular to an irregularly shaped seismic isolation cover plate and a seismic isolation cover plate structure applied to a location adjacent to a sunken courtyard. Background Technology

[0002] In architectural design, sunken courtyards are a common and effective technique for improving lighting conditions and enhancing the comfort of basement areas. By creating an open space below ground level around the basement, a sunken courtyard allows natural light to enter, thus meeting the building's lighting requirements. To ensure the structural stability and safety of the sunken courtyard, retaining walls are typically erected around it. These retaining walls primarily serve to prevent water and soil from entering the courtyard, ensuring the normal use of the sunken courtyard and basement.

[0003] Meanwhile, for seismically isolated buildings, to achieve their seismic isolation function and reduce earthquake damage to the main structure, a seismic isolation trench needs to be installed around the building. The seismic isolation trench is an indispensable structure in seismically isolated buildings; its function is to provide the building with sufficient space to move during an earthquake, preventing the surrounding soil from restricting its free movement. To prevent debris from falling into the trench and affecting the seismic isolation effect, and to ensure the safety of personnel and equipment, the trench is usually sealed with a seismic isolation cover. During an earthquake, the seismically isolated building can move relative to the area defined by the width of the trench, thereby dissipating seismic energy and achieving the purpose of vibration reduction.

[0004] However, in actual building layouts, when sunken courtyards are placed adjacent to the outer contour of seismic isolation buildings, a contradiction arises in functional requirements: on the one hand, the seismic isolation cover plate needs to move along with the seismic isolation building during earthquakes to adapt to the relative displacement of the building; on the other hand, the retaining wall of the sunken courtyard must form a closed enclosure structure to achieve the functions of water and soil retention. This contradiction greatly limits the placement of sunken courtyards in seismic isolation buildings, making it difficult for designers to design according to the ideal functional layout of the building. Utility Model Content

This is to solve the problem in the prior art where there is a contradiction between the activity requirements of the irregularly shaped seismic isolation cover plate during an earthquake and the enclosure requirements of the retaining wall of the sunken courtyard, which leads to the limitation of the layout of the sunken courtyard and the difficulty in realizing the functional layout of the building. This invention enables the flexible layout of the sunken courtyard in a seismic isolation building, while meeting the functional requirements of seismic isolation and water blocking.

[0006] This utility model provides an irregularly shaped seismic isolation cover plate, which is disposed adjacent to a seismic isolation building and a sunken courtyard, respectively. It includes: a horizontal portion, with a drainage ditch disposed adjacent to the seismic isolation building, the horizontal portion covering the drainage ditch; and a vertical portion, vertically disposed at the edge of the horizontal portion. A retaining wall for enclosing the sunken courtyard is disposed outside the seismic isolation building, the retaining wall having an opening adapted to the shape of the vertical portion. When the horizontal portion of the irregularly shaped seismic isolation cover plate covers the drainage ditch, the vertical portion blocks the opening in the retaining wall, forming part of the retaining wall.

[0009] According to one embodiment of the present invention, the vertical part has a first inclined surface formed on the edge away from the seismic isolation building; the vertical part is in contact with the complementary inclined surface of the retaining wall on the corresponding side through the first inclined surface.

[0010] According to one embodiment of the present invention, a joint sealant is provided between the stepped surface and the first inclined surface and the retaining wall.

[0011] According to one embodiment of the present invention, a second inclined surface is provided on one side edge of the horizontal portion, so that when the irregularly shaped vibration isolation cover is affected by an external force in the horizontal direction, it can slide away from its original position through the second inclined surface.

[0012] According to one embodiment of the present invention, a third inclined surface is provided on the other side edge of the horizontal part, and the second inclined surface and the third inclined surface are respectively located on the opposite side of the vertical part and the opposite side of the seismic isolation building.

[0013] This utility model also provides a seismic isolation cover plate structure applied to a location adjacent to a sunken courtyard, comprising: a seismic isolation building, on one side of which a sunken courtyard is provided; a retaining wall connected to the outer wall of the seismic isolation building to enclose the sunken courtyard and achieve the function of retaining soil; a seismic isolation ditch adjacent to the seismic isolation building is provided in the inner area of ​​the retaining wall, and a drainage ditch is located outside the seismic isolation ditch; an irregularly shaped seismic isolation cover plate of the above embodiment is provided above the drainage ditch.

[0014] According to one embodiment of the present invention, along the extension direction of the seismic isolation ditch and the drainage ditch, a plurality of sequentially adjacent ordinary cover plates are provided on the inner side of the retaining wall; wherein, the irregularly shaped seismic isolation cover plate is located adjacent to the sunken courtyard.

[0015] According to one embodiment of the present invention, a seismic isolation ditch retaining wall is provided between the seismic isolation ditch and the drainage ditch, and a seismic isolation support is provided at the bottom of the seismic isolation building; a cover plate structure is provided above the seismic isolation ditch.

[0016] The irregularly shaped seismic isolation cover plate and the seismic isolation cover plate structure applied to the location adjacent to the sunken courtyard provided by this utility model are designed as a structure including a horizontal part and a vertical part. The horizontal part covers the drainage ditch next to the seismic isolation building, and the vertical part is embedded in the corresponding notch at the bottom of the retaining wall of the sunken courtyard and forms part of the retaining wall. This allows the irregularly shaped seismic isolation cover plate to move with the seismic isolation building during earthquakes and to cooperate with the retaining wall to achieve an effective water-blocking function, thereby resolving the contradiction between the two.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] In the description of the embodiments of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. It should also be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] This utility model is applicable to scenarios where seismic isolation buildings are adjacent to sunken courtyards. When the sunken courtyard is close to the outer contour of the seismic isolation building, by setting an irregularly shaped movable seismic isolation cover plate, two key functions can be achieved simultaneously: on the one hand, it can enclose the sunken courtyard with a retaining wall, meeting the requirements for water and soil retention; on the other hand, it can prevent the courtyard retaining wall from obstructing the movement of the building above the seismic isolation layer during an earthquake. This irregularly shaped seismic isolation cover plate, which combines the irregularly shaped seismic isolation cover plate with the sunken courtyard retaining wall, can ensure that the sunken courtyard retaining wall forms an effective enclosure while preventing the retaining wall from restricting the free movement of the seismic isolation building, thus properly resolving the contradiction between the two.

[0028] The following is combined Figures 1-6 This invention describes the specific implementation of the irregularly shaped seismic isolation cover plate and the seismic isolation cover plate structure applied to a location adjacent to a sunken courtyard.

[0029] like Figure 1 and Figure 2 As shown, this utility model provides an irregularly shaped seismic isolation cover plate, which is disposed adjacent to the seismic isolation building and the sunken courtyard 23 respectively. It includes: a horizontal part 11, with a drainage ditch 21 disposed adjacent to the seismic isolation building, and the horizontal part 11 covering the drainage ditch 21; a vertical part 12, which is vertically disposed at the edge of the horizontal part 11, and a retaining wall 22 for enclosing the sunken courtyard 23 is disposed around the perimeter of the sunken courtyard 23 (outside the seismic isolation building), and the retaining wall 22 is provided with an opening adapted to the shape of the vertical part 12; when the horizontal part 11 of the irregularly shaped seismic isolation cover plate covers the drainage ditch 21, the vertical part 12 blocks the opening of the retaining wall 22, forming part of the retaining wall 22.

[0030] Specifically, the structural design of this irregularly shaped seismic isolation cover plate closely fits the special scenario of the seismic isolation building adjacent to the sunken courtyard 23, achieving functional integration through the synergistic action of the horizontal part 11 and the vertical part 12. The horizontal part 11, as the base of the cover plate, directly covers the drainage ditch 21 next to the seismic isolation building, which can both seal the drainage ditch 21 to prevent debris from falling in and affecting the drainage function, and provide a flat surface for personnel or equipment passage. The vertical part 12 is vertically connected to the edge of the horizontal part 11, and its size and shape perfectly match the opening at the bottom of the retaining wall 22 of the sunken courtyard 23. When the horizontal part 11 covers the drainage ditch 21, the vertical part 12 fits perfectly into the opening, forming a complete closed structure with the retaining wall 22, jointly undertaking the functions of water and soil retention, ensuring that water and soil around the sunken courtyard 23 do not seep in.

[0031] In use, this irregularly shaped seismic isolation cover plate plays a crucial role in both static and dynamic scenarios. Under normal, non-earthquake conditions, the horizontal section 11 stably covers the drainage ditch 21, while the vertical section 12 closely cooperates with the retaining wall 22 to form a closed enclosure, ensuring the structural safety and normal use of the sunken courtyard 23 and the area surrounding the seismic isolation building. However, during an earthquake, the seismic isolation building will experience relative movement within the width of the seismic isolation ditch 24. Because the irregularly shaped seismic isolation cover plate is installed adjacent to the seismic isolation building, it will move along with the building. At this time, although the vertical section 12 displaces through the opening in the retaining wall 22, it avoids the retaining wall 22 restricting the seismic isolation movement of the building.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, according to the present invention, a portion of the retaining wall 22 is directly connected to the seismic isolation building; the vertical portion 12 has a stepped surface 13 formed on its edge near the seismic isolation building; a positioning component is provided between the stepped surface 13 and the retaining wall 22 connected to the seismic isolation building to fix the stepped surface 13 of the vertical portion 12 to that portion of the retaining wall 22. Specifically, the retaining wall 22 is not completely independent of the seismic isolation building, but a portion is directly connected to the seismic isolation building, forming a stable connection structure. This portion of the retaining wall 22 serves both as a conventional water barrier and as a reference and support for the installation of the irregularly shaped seismic isolation cover. For the vertical portion 12 of the irregularly shaped seismic isolation cover, its edge near the seismic isolation building is designed as a stepped surface 13. This stepped structural design is compatible with the structure of the portion of the retaining wall 22 connected to the seismic isolation building, enabling a tight fit and connection between the two.

[0033] To further ensure the stability of the connection between the vertical section 12 and the retaining wall 22, a positioning component is preferably installed between the stepped surface 13 and the retaining wall 22 connected to the seismic isolation building. This positioning component can be a structure with mating protrusions and grooves, bolts and screw holes, etc. When the irregularly shaped seismic isolation cover is installed in place, the positioning component can accurately and firmly fix the stepped surface 13 of the vertical section 12 to the corresponding part of the retaining wall 22. In non-earthquake conditions, the irregularly shaped seismic isolation cover and the retaining wall 22 form an integrated closed structure, effectively ensuring water-blocking performance. During an earthquake, as the seismic isolation building moves, the positioning component can maintain a certain connection during movement, preventing excessive displacement or detachment of the irregularly shaped seismic isolation cover.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, according to the present invention, a non-circular vibration isolation cover plate includes a positioning component comprising multiple positioning holes 14 disposed on a stepped surface 13, the opening direction of which is perpendicular to the surface of the vertical part 12; the positioning component also includes a positioning clip 15 disposed between the vertical part 12 and the retaining wall 22, the positioning clip 15 being detachably installed on the vertical part 12 through the positioning holes 14. Specifically, multiple positioning holes 14 are spaced apart along the length of the stepped surface 13 of the vertical part 12 of the non-circular vibration isolation cover plate, the opening direction of which is perpendicular to the surface of the vertical part 12, ensuring that the subsequent installation direction of the positioning clip 15 effectively matches the retaining wall 22. The positioning clip 15, as a key component connecting the vertical part 12 and the retaining wall 22, has a shape and size that matches the positioning holes 14 and the corresponding connection parts of the retaining wall 22. During installation, the positioning clip 15 passes through the positioning holes 14 and forms a detachable connection with the vertical part 12. Meanwhile, the other end of the positioning clip 15 is embedded in the retaining wall 22, thereby connecting the stepped surface 13 of the vertical part 12 to that part of the retaining wall 22. According to the above scheme, on the one hand, the setting of multiple positioning holes 14 can adjust the installation position of the positioning clip 15 according to actual installation needs, improving adaptability; on the other hand, the detachable connection method facilitates later maintenance, replacement or adjustment.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, according to the present invention, a non-circular seismic isolation cover plate has a first inclined surface 16 formed on the edge of the vertical part 12 away from the seismic isolation building. The vertical part 12 is fitted with the complementary inclined surface of the retaining wall 22 on the corresponding side through the first inclined surface 16. The edge of the vertical part 12 away from the seismic isolation building is designed as the first inclined surface 16, and the inclination angle and extension length of the inclined surface are specially set according to the structural characteristics of the retaining wall 22 on the corresponding side. The retaining wall 22 connected to the vertical part 12 on this side has an inclined surface near the edge of the vertical part 12 that is completely complementary to the first inclined surface 16, that is, the inclination directions of the two are opposite but the angles are the same, which can achieve a tight fit.

[0036] The aforementioned complementary inclined surface mating structure is similar to a "ramp-and-mouth" structure. In non-earthquake conditions, the first inclined surface 16 of the vertical part 12 fits tightly with the complementary inclined surface of the retaining wall 22, forming a seamless connection. Furthermore, this inclined surface mating method reduces stress concentration compared to a right-angle connection. When an earthquake occurs and the seismic isolation building causes displacement of the irregularly shaped seismic isolation cover plate, the vertical part 12 will move with the seismic isolation building. At this time, relative sliding will occur between the first inclined surface 16 and the complementary inclined surface of the retaining wall 22. Because the inclined surface design provides a certain margin of movement for both, it will not hinder the movement of the seismic isolation building due to rigid collision, unlike a right-angled tongue and groove joint.

[0037] Furthermore, according to the irregularly shaped seismic isolation cover plate of this utility model, a joint sealant is provided between the stepped surface 13 and the first inclined surface 16 and the retaining wall 22, respectively. Joint sealant is provided between the stepped surface 13 of the vertical portion 12 of the irregularly shaped seismic isolation cover plate and the retaining wall 22 connected to the seismic isolation building, and between the first inclined surface 16 of the vertical portion 12 and the complementary inclined surface of the corresponding side retaining wall 22. This joint sealant has good elasticity, weather resistance, and adhesion, and can tightly fill the tiny gaps between the stepped surface 13 and the retaining wall 22, and between the first inclined surface 16 and the complementary inclined surface.

[0038] In non-earthquake conditions, the sealant can further enhance the sealing of the connection between the irregular seismic isolation cover plate and the retaining wall 22, effectively preventing rainwater, groundwater and soil from seeping into the sunken courtyard 23 or drainage ditch 21 through the gaps, ensuring the normal use of the sunken courtyard 23 and the surrounding environment of the seismic isolation building, while also reducing the adverse effects of external debris entering the gaps on the structure.

[0039] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, according to this utility model, a non-circular seismic isolation cover plate has a second inclined surface 17 on one side edge of the horizontal part 11. This inclined surface 17 allows the non-circular seismic isolation cover plate to slide away from its original position when subjected to a horizontal external force. Specifically, the second inclined surface 17 is located at the junction of the horizontal part 11 with the outdoor ground or an adjacent cover plate, and its inclination direction and angle are precisely designed. Under normal use, this inclined surface forms a smooth connection with the surrounding structure, ensuring safe passage for personnel. Simultaneously, in conjunction with the relevant structures at the retaining wall 22, it prevents the non-circular seismic isolation cover plate from accidentally falling into the sunken courtyard 23. When an earthquake occurs and the seismic isolation building shifts towards the sunken courtyard 23, it exerts a horizontal compressive force on the non-circular seismic isolation cover plate. At this time, the second inclined surface 17 acts as a guide, allowing the non-circular seismic isolation cover plate to slide smoothly along the inclined surface, thereby pushing it outwards from its original position. This avoids restricting the displacement of the seismic isolation building due to rigid obstruction, ensuring the normal functioning of the seismic isolation function.

[0040] Furthermore, according to the present invention, a third inclined surface 18 is provided on the other edge of the horizontal part 11. The second inclined surface 17 and the third inclined surface 18 are respectively located on the opposite side of the vertical part 12 and the opposite side of the seismic isolation building. The third inclined surface 18 is positioned in correspondence with the second inclined surface 17, guiding and constraining the movement of the irregularly shaped seismic isolation cover from the other side. During normal use, the third inclined surface 18 is tightly fitted with the drainage ditch structure around the seismic isolation building, maintaining the stable installation state of the irregularly shaped seismic isolation cover. When an earthquake occurs and the seismic isolation building displaces away from the sunken courtyard 23, the third inclined surface 18 works in conjunction with the locking mechanism on the irregularly shaped seismic isolation cover. On the one hand, the inclined structure avoids obstructing the displacement of the seismic isolation building; on the other hand, the limiting function of the locking mechanism prevents the irregularly shaped seismic isolation cover from sliding into the drainage ditch 21 due to excessive displacement, ensuring the safety and functionality of the irregularly shaped seismic isolation cover during an earthquake.

[0041] The following describes the seismic isolation cover plate structure applied to the location adjacent to the sunken courtyard provided by this utility model. The seismic isolation cover plate structure applied to the location adjacent to the sunken courtyard described below can be referred to in correspondence with the irregular seismic isolation cover plate described above.

[0042] like Figure 2 and Figure 4 As shown, this utility model also provides a seismic isolation cover structure applied to a location adjacent to a sunken courtyard, comprising: a seismic isolation building with a sunken courtyard 23 on one side; a retaining wall 22 connected to the outer wall of the seismic isolation building to enclose the sunken courtyard 23 and achieve a retaining function; a seismic isolation ditch 24 adjacent to the seismic isolation building and a drainage ditch 21 located outside the seismic isolation ditch 24 are provided in the inner area of ​​the retaining wall 22; and an irregularly shaped seismic isolation cover plate as described above is provided above the drainage ditch 21. Specifically, the seismic isolation building serves as the main structure, with its outer wall connected to the retaining wall 22. The retaining wall 22, through a reasonable layout, divides the space on one side of the seismic isolation building into two functionally distinct areas: the sunken courtyard 23 and the seismic isolation area. The sunken courtyard 23 is mainly used to achieve functions such as natural lighting in the basement, while the seismic isolation area is the key area to ensure the seismic performance of the seismic isolation building. Within the seismic isolation zone, the seismic isolation trench 24 is positioned adjacent to the seismic isolation building, providing necessary space for the relative movement of the building during an earthquake. The drainage ditch 21 is located outside the seismic isolation trench 24, which can promptly drain accumulated water within the zone, preventing moisture from affecting the seismic isolation structure. The aforementioned irregularly shaped seismic isolation cover plate covers the drainage ditch 21, with its vertical part 12 embedded in the opening of the retaining wall 22. This not only seals off the drainage ditch 21 but also supplements the enclosure function of the retaining wall 22, creating an orderly separation between the seismic isolation zone and the sunken courtyard 23, while simultaneously meeting the requirements for seismic isolation and water retention.

[0043] Furthermore, according to a seismic isolation cover structure applied to a location adjacent to a sunken courtyard according to this utility model, multiple ordinary cover plates 25 are arranged sequentially adjacent to each other along the extension direction of the seismic isolation ditch 24 and the drainage ditch 21; among them, the irregularly shaped seismic isolation cover plate is located adjacent to the sunken courtyard 23. Since the seismic isolation ditch 24 and the drainage ditch 21 usually extend a certain length along the outer wall of the seismic isolation building, multiple ordinary cover plates 25 are arranged along their extension direction in order to fully cover the entire seismic isolation area. These ordinary cover plates 25 mainly serve to close the seismic isolation ditch 24 and the drainage ditch 21 and ensure passage safety. Considering the special requirements of the location of the sunken courtyard 23 adjacent to the seismic isolation building, that is, it is necessary to simultaneously meet the requirements of enclosure by the retaining wall 22 and seismic isolation activities, the aforementioned irregularly shaped seismic isolation cover plate is arranged at a specific location adjacent to the sunken courtyard 23. In this way, the ordinary cover plate 25 and the irregular seismic isolation cover plate work together to achieve overall coverage of the seismic isolation area, and can also solve functional contradictions at key locations through the special structure of the irregular seismic isolation cover plate, making the layout of the entire seismic isolation building structure more reasonable and the function more complete.

[0044] Furthermore, according to a seismic isolation cover structure applied to a location adjacent to a sunken courtyard, a seismic isolation trench retaining wall 26 is provided between the seismic isolation trench 24 and the drainage trench 21, and a seismic isolation bearing 27 is provided at the bottom of the seismic isolation building; a cover structure 28 is provided above the seismic isolation trench 24. The seismic isolation trench retaining wall 26 between the seismic isolation trench 24 and the drainage trench 21 serves to separate the two, preventing water or debris from the drainage trench 21 from entering the seismic isolation trench 24, ensuring the stability of the environment within the seismic isolation layer. The aforementioned seismic isolation bearing 27 is a core component of the seismic isolation building, which can effectively reduce the transmission of seismic forces to the structure above the seismic isolation layer, greatly reducing building damage. The cover structure 28 is integrated with the seismic isolation building, and its function is to seal the seismic isolation layer.

[0045] The aforementioned seismic isolation bearings 27 are located at the bottom of the seismically isolated building and come in various types, including natural rubber bearings, lead-core rubber bearings, and friction pendulum bearings. Natural rubber bearings are made of multiple layers of rubber sheets and thin steel plates, alternately laminated and vulcanized, possessing excellent elasticity and load-bearing capacity. Under normal conditions, natural rubber bearings stably support the weight of the seismically isolated building, ensuring its normal use. During an earthquake, the rubber layers undergo significant horizontal deformation, absorbing seismic energy through their elastic deformation and slowing the transmission of seismic waves to the superstructure. Lead-core rubber bearings, on the other hand, have a lead core at the center of the natural rubber bearing. The lead core has excellent plastic deformation capacity; under seismic action, the lead core undergoes shear deformation, further dissipating seismic energy. Simultaneously, the rubber layers provide elastic restoring force, allowing the bearing to essentially return to its original position after an earthquake, thus combining energy dissipation and repositioning functions. Friction pendulum seismic isolation bearings typically consist of upper and lower connecting plates and a friction material in the middle. When the earthquake intensity reaches a certain level, relative slippage will occur between the upper connecting plate and the middle friction material. The seismic energy is consumed through friction, and the displacement generated by the slippage isolates the seismic action, reducing the seismic force transmitted to the upper part of the building. It is suitable for some scenarios where the displacement restriction requirements are relatively relaxed.
