Description

Technical Field

[0001] This application relates to the technical field of building seismic isolation, and particularly to a building seismic isolation trench. Background Art

[0002] Currently, when buildings are isolated and dampened, a building seismic isolation trench structure is usually adopted, that is, the upper building and the lower building are connected by a seismic isolation cushion layer. When an earthquake occurs, the seismic isolation cushion layer can play a buffering role and reduce the mutual collision force between the upper building and the lower building, so as to achieve the purpose of seismic isolation and damping.

[0003] In the actual application of the above seismic isolation trench structure, a drainage or water interception structure needs to be set up to avoid the damage of the building structure caused by rainwater leakage and other situations. The practice of the seismic isolation trench cover plate is recorded in the existing national standard atlas "Detailed Drawings of Building Seismic Isolation Structures" 22G610-1, and a drainage ditch is used to drain the seismic isolation trench structure.

[0004] In the above drainage ditch structure, two precast cover plates are used to seal the seismic isolation trench and the drainage ditch respectively, and building sealant is used to fill the joints between the two precast cover plates. After long-term use, cracks are likely to appear at the joints under the action of thermal expansion and contraction, resulting in the failure of the drainage and water interception system, so that rainwater can enter the seismic isolation layer through the gaps. Summary of the Utility Model

[0005] In order to ensure the drainage and water interception functions of the seismic isolation trench structure, this application provides a building seismic isolation trench.

[0006] A building seismic isolation trench provided by this application adopts the following technical solutions:

[0007] A building seismic isolation trench is arranged between the upper building and the underground building, and includes a drainage ditch, a precast cover plate, a connecting component and a seismic isolation component; the drainage ditch is arranged on the periphery of the underground building; the precast cover plate covers the top of the drainage ditch, and a water leakage hole is opened on the precast cover plate, and the water leakage hole is communicated with the drainage ditch; weather-resistant glue is used to fill the joint between the end of the precast cover plate far from the upper building and the drainage ditch; the connecting component is arranged between the precast cover plate and the upper building, and the end of the precast cover plate close to the upper building is fixedly connected to the upper building through the connecting component; the seismic isolation component is arranged between the upper building and the underground building and is used for buffering and isolating the upper building during an earthquake.

[0008] By adopting the above technical solutions, during an earthquake, the superstructure is buffered and isolated by the seismic isolation components, thereby improving the overall durability of the building; by providing a drainage ditch, rainwater on the ground can flow into the drainage ditch through the water leakage holes and then be discharged through the drainage ditch, preventing rainwater from seeping into the underground building and damaging the building structure; one end of the precast cover plate is fixedly connected to the superstructure under the action of the connecting components, and the other end is caulked with the underground building by weather-resistant glue. When the building deforms and cracks due to thermal expansion and contraction, the cracks will concentrate at the caulked part of the weather-resistant glue. Even if rainwater seeps through the cracks, it will only enter the drainage ditch and then be discharged from the drainage ditch, and will not enter the underground building, thus ensuring that the drainage and water interception functions of the seismic isolation ditch structure will not fail.

[0009] Optionally, the drainage ditch is integrally cast, and waterproof coiled materials are provided on both the outer side wall and the inner side wall of the drainage ditch.

[0010] By adopting the above technical solutions, the drainage ditch is integrally cast, avoiding the generation of internal gaps in the drainage ditch due to construction reasons, and thus cooperating with the waterproof coiled materials to ensure the waterproof performance of the drainage ditch and prevent leakage.

[0011] Optionally, the connecting components include an embedded steel sleeve and an embedded bolt; the embedded steel sleeve is embedded inside the superstructure; one end of the embedded bolt is embedded inside the precast cover plate, and the embedded bolt is used in cooperation with the embedded steel sleeve.

[0012] By adopting the above technical solutions, the cooperation between the embedded steel sleeve and the embedded bolt realizes the fixed connection of one end of the precast cover plate to the superstructure.

[0013] Optionally, the end face of the precast cover plate away from the embedded bolt is inclined; the top end face of the side wall of the drainage ditch away from the embedded steel sleeve is inclined, and the inclined end of the precast cover plate is adapted to the inclined end of the drainage ditch.

[0014] By adopting the above technical solutions, a friction pendulum seismic isolation bearing structure is formed between the precast cover plate and the side wall of the drainage ditch. On the one hand, the installation is simple. During installation, only simple adjustment and alignment of the precast cover plate and the side wall of the drainage ditch are required, without the need for additional tools, and the later maintenance is also simple.

[0015] Optionally, a slope is provided on the superstructure, and the slope is located on the side of the precast cover plate close to the superstructure. The height of the slope gradually decreases in the direction close to the precast cover plate, and the lowest height of the slope is the same as the height of the precast cover plate.

[0016] By adopting the above technical solution, a slope is arranged between the precast cover plate and the superstructure, so that the rainwater falling near the superstructure can flow along the slope into the drainage ditch and be discharged, thereby further improving the drainage and water interception functions of the seismic isolation ditch structure.

[0017] Optionally, the top wall of the precast cover plate is kept level with the surface of the outdoor ground floor.

[0018] By adopting the above technical solution, the precast cover plate and the outdoor ground floor are kept level, improving the aesthetics of the overall building structure.

[0019] Optionally, the seismic isolation component includes a connecting column, a seismic isolation bearing and a seismic isolation cushion layer; the connecting column is fixedly connected to the superstructure; the seismic isolation bearing is fixedly arranged between the connecting column and the underground building; the seismic isolation cushion layer is fixedly arranged between the superstructure and the underground building.

[0020] By adopting the above technical solution, a seismic isolation bearing and a seismic isolation cushion layer are arranged between the superstructure and the underground building. During an earthquake, the seismic isolation bearing and the seismic isolation cushion layer act together to buffer between the underground building and the superstructure, avoiding damage to the building structure, thereby realizing the function of seismic isolation and shock absorption.

[0021] Optionally, a weather-resistant sealant is also used to fill the gap between one end of the slope close to the superstructure and the superstructure.

[0022] By adopting the above technical solution, it is avoided that the rainwater flowing down along the superstructure leaks through the gap between the superstructure and the slope, thereby improving the waterproof performance of the building structure.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up the connecting component, one end of the precast cover plate is fixedly connected to the superstructure under the action of the connecting component, and the other end is filled with a weather-resistant sealant with the underground building. When the building deforms and cracks under the action of thermal expansion and contraction, the cracks will concentrate at the weather-resistant sealant filling. Even if the rainwater penetrates from the cracks, it will only enter the drainage ditch and then be discharged from the drainage ditch, and will not enter the underground building, thereby ensuring that the drainage and water interception functions of the seismic isolation ditch structure will not fail;

[0025] 2. By setting up the slope, a slope is arranged between the precast cover plate and the superstructure, so that the rainwater falling near the superstructure can flow along the slope into the drainage ditch and be discharged, thereby further improving the drainage and water interception functions of the seismic isolation ditch structure;

[0026] 3. By setting up the seismic isolation components, a seismic isolation bearing and a seismic isolation cushion layer are arranged between the superstructure and the underground structure. During an earthquake, the seismic isolation bearing and the seismic isolation cushion layer work together to buffer between the underground structure and the superstructure, avoiding damage to the building structure, thereby achieving the effect of seismic isolation and shock absorption.

[0036] The following further elaborates on the present application in conjunction with the attached Figure 1-2 drawings.

[0037] An embodiment of the present application discloses a building seismic isolation trench. Referring to Figure 1 and Figure 2 , a building seismic isolation trench is arranged between the superstructure 1 and the underground structure 2, and includes a seismic isolation component 6. The seismic isolation component 6 includes a connection column 61, a seismic isolation bearing 62, and a seismic isolation cushion layer 63. The connection column 61 is arranged vertically, and the top of the connection column 61 is fixedly connected to the superstructure 1. The seismic isolation column adopts a laminated seismic isolation bearing 62, and the seismic isolation bearing 62 is fixedly arranged between the connection column 61 and the underground structure 2. The seismic isolation cushion layer 63 is fixedly arranged between the side walls of the superstructure 1 and the underground structure 2.

[0038] The superstructure 1 and the underground structure 2 are supported by connecting columns 61 and seismic isolation bearings 62. When an earthquake occurs, the seismic isolation bearings 62 can buffer and reduce most of the energy, so that the superstructure 1 remains stable. A seismic isolation cushion layer 63 is arranged between the side walls of the superstructure 1 and the underground structure 2. When an earthquake occurs and the underground structure 2 shakes, the seismic isolation cushion layer 63 can buffer the side wall of the underground structure 2 and prevent damage to the superstructure 1, thus achieving the function of seismic isolation and shock absorption.

[0039] Refer to Figure 1 and Figure 2 As shown in and, a drainage ditch 3 and a precast cover plate 4 are arranged on the underground structure 2. The drainage ditch 3 is arranged on the periphery of the underground structure 2 and is integrally cast. Waterproof coiled materials 31 are fixedly laid on both the outer side wall and the inner side wall of the drainage ditch 3. The precast cover plate 4 covers the top opening of the drainage ditch 3. A number of water leakage holes are provided on the precast cover plate 4, and the water leakage holes are communicated with the inside of the drainage ditch 3. In order to maintain the aesthetic appearance of the building, in this embodiment, the top wall of the precast cover plate 4 is flush with the surface of the outdoor ground level.

[0040] Refer to Figure 2 As shown in, one end of the precast cover plate 4 away from the superstructure 1 is an inclined end, and the end face of the inclined end of the precast cover plate 4 is inclined upward along the direction away from the superstructure 1. The top end of the side wall of the drainage ditch 3 away from the superstructure 1 is an inclined end, and the end face of the inclined end of the side wall of the drainage ditch 3 is inclined upward along the direction away from the superstructure 1. The inclination angles of the two are the same. The inclined end of the precast cover plate 4 is adapted to the inclined end of the drainage ditch 3 to form a friction pendulum seismic isolation bearing 62 structure. The gap between the inclined end of the precast cover plate 4 and the inclined end of the side wall of the drainage ditch 3 is filled with weather-resistant glue.

[0041] A connecting component 5 is arranged on the superstructure 1, and the connecting component 5 is arranged at one end of the precast cover plate 4 close to the superstructure 1. The connecting component 5 includes a pre-embedded steel sleeve 51 and a pre-embedded bolt 52. The pre-embedded steel sleeve 51 is vertically arranged inside the superstructure 1 and is located at the bottom of the precast cover plate 4. The pre-embedded steel sleeve 51 is pre-embedded into the concrete when the superstructure 1 is being poured. One end of the pre-embedded bolt 52 is arranged inside the precast cover plate 4 and is located at one end of the precast cover plate 4 close to the superstructure 1. The pre-embedded bolt 52 is pre-embedded inside the precast cover plate 4 when the precast cover plate 4 is being poured. The pre-embedded bolt 52 is used in cooperation with the pre-embedded steel sleeve 51.

[0042] On a rainy day, after the rain falls, it can flow into the drainage ditch 3 through the water leakage holes on the precast cover plate 4 and then drain out along the drainage ditch 3, thus preventing rainwater from entering the underground structure 2 and playing a role in drainage and water interception.

[0043] Under the action of the embedded steel casing 51 and the embedded bolts 52, one end of the precast cover plate 4 is fixed to the superstructure 1, while the other end is filled with weather-resistant glue which is relatively soft in texture. When the building deforms and cracks due to thermal expansion and contraction, the cracks will concentrate at the weather-resistant glue filling. Even if rainwater penetrates from the cracks, it will only enter the drainage ditch 3 and then be discharged from the drainage ditch 3, and will not enter the underground building 2. Therefore, the drainage and water interception functions will not fail. For the overall beauty of the building, the filling can be regularly repaired in the later stage, and even if the filling is not repaired due to objective reasons in the later stage, the drainage and water interception functions of the building will not fail.

[0044] Refer to Figure 1 and Figure 2 , a slope 11 is provided on the superstructure 1. The slope 11 is located on the side of the precast cover plate 4 close to the superstructure 1. The slope 11 is integrally cast with the superstructure 1. The height of the slope 11 gradually decreases along the direction close to the precast cover plate 4, and the lowest height of the slope 11 is the same as the height of the precast cover plate 4. The gap between one end of the slope 11 close to the superstructure 1 and the superstructure 1 is also filled with weather-resistant glue.

[0045] Utilize the height difference of the slope 11 to divert the rainwater flowing down along the superstructure 1, so that the rainwater can flow into the drainage ditch 3 and be discharged, thereby avoiding the phenomenon of rainwater leakage. Filling the gap between one end of the slope 11 close to the superstructure 1 and the superstructure 1 with weather-resistant glue can also prevent rainwater from leaking through the gap at the corner of the wall.

[0046] The implementation principle of an architectural isolation trench in an embodiment of the present application is as follows:

[0047] The superstructure 1 and the underground building 2 are supported by connecting columns 61 and isolation bearings 62. When an earthquake occurs, the isolation bearings 62 can buffer and reduce most of the energy, so that the superstructure 1 remains stable. An isolation cushion layer 63 is arranged between the side walls of the superstructure 1 and the underground building 2. When an earthquake occurs and the underground building 2 shakes, the isolation cushion layer 63 can buffer the side wall of the underground building 2 and prevent damage to the superstructure 1, thereby achieving the function of seismic isolation and shock absorption.

[0048] On a rainy day, after the rain falls, it can flow into the drainage ditch 3 through the water leakage holes on the precast cover plate 4, and then flow out along the drainage ditch 3, thereby preventing the rainwater from entering the underground building 2 and playing the role of drainage and water interception. Utilize the height difference of the slope 11 to divert the rainwater flowing down along the superstructure 1, so that the rainwater can flow into the drainage ditch 3 and be discharged, thereby avoiding the phenomenon of rainwater leakage.

[0049] Under the action of the embedded steel casing 51 and the embedded bolts 52, one end of the precast cover plate 4 is fixed to the superstructure 1, while the other end is filled with weather-resistant glue with relatively soft texture. When the building deforms and cracks under the action of thermal expansion and contraction, the cracks will concentrate at the weather-resistant glue filling. Even if rainwater penetrates from the cracks, it will only enter the drainage ditch 3 and then drain out from the drainage ditch 3, and will not enter the underground building 2. Therefore, the drainage and water interception functions will not fail.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
