[0036] Currently, in building structures, a seismic isolation trench is also provided between the air shaft structure and the main building. A cover plate member needs to be provided on the upper part of the seismic isolation trench, and the selection of the cover plate member should have a certain support strength and stiffness. However, during an earthquake, the setting of the cover plate member should not hinder the movement of the building in all directions due to vibration. At the air shaft position, in the prior art, the cover plate member is usually fixed between the main building structure and the air shaft structure. This fixed connection installation method will hinder the movement of the building during an earthquake and will have a certain impact on the seismic isolation effect of the seismic isolation member. In addition, in order to meet the stiffness requirements, the traditional cover plate member generally has a relatively thick specification, which is not conducive to later replacement and maintenance.

[0037] To solve the above problems, the present utility model proposes a structure for a seismic isolation trench of an above-ground air shaft Figures 1 to 4 FIG. is a schematic structural diagram of an embodiment provided for the structure 1000 of the seismic isolation trench of the above-ground air shaft of the present utility model.

[0038] Please refer toFigures 1 to 4 , the present utility model proposes a structure of a seismic isolation trench for an above-ground air shaft 1000. Among them, one end of the air shaft structure 14 is located above the ground. The lower end of the air shaft structure 14 and the lower support 132 of the seismic isolation support 13 are both installed on the bottom beam 12 of the building. The upper wall 11 is installed on the upper support 131 of the seismic isolation support 13. The area between the air shaft structure 14 and the seismic isolation support 13 is the seismic isolation trench 8. Usually, the upper end of the seismic isolation trench 8 is located above the ground. In order to prevent living things, rainwater or other things from falling into the seismic isolation trench 8, a corresponding covering structure is usually provided to cover the upper end of the seismic isolation trench 8. However, the traditional covering structure often fixes a steel plate member 2 between the air shaft structure 14 and the upper wall 11 above the seismic isolation trench 8. This traditional covering method forms a fixed connection between the upper end of the air shaft structure 14 and the upper wall 11, making it impossible for the end of the air shaft structure 14 to move relative to the upper support 131, which will affect the seismic isolation effect of the seismic isolation support 13 on the building and the air shaft structure 14. Therefore, in this embodiment, one end of the steel plate member 2 in the covering structure is connected to the air shaft structure 14, and the other end is lapped on the upper wall 11 and can move freely. This shielding structure can achieve a good shielding effect without affecting the seismic isolation effect of the seismic isolation support 13. At the same time, considering that the steel plate member 2 not only has a simple shielding effect in actual use but also needs to meet the trampling support for pedestrians. In this embodiment, a support member is movably installed between the air shaft structure 14 and the upper wall 11. The support member is movably installed so that relative movement can occur between the upper end of the air shaft structure 14 and the upper wall 11, thus not affecting the use effect of the seismic isolation support 13. Moreover, after one end of the steel plate member 2 is fixedly installed on the support member, the support member can also fixedly support the downward end of the steel plate member 2. At this time, the weight that the steel plate member 2 can bear is greatly increased, and through this kind of structure setting, the thickness of the steel plate member 2 can be minimized as much as possible in actual application, making the installation and adjustment of the steel plate member 2 more convenient.

[0039] Among them, the first fixing member 3 and the second fixing member 4 in the support member are respectively installed at the upper wall 11 and the air shaft opening 141. The above two fixing members are separated from each other, and the partition net member 7 is installed between the first fixing member 3 and the second fixing member 4. It should be noted that after the partition net member 7 is installed between the first fixing member 3 and the second fixing member 4, the partition net member 7 can move freely between the first fixing member 3 and the second fixing frame, so that the partition net member 7 does not have a connecting effect in the horizontal direction, but only has a supporting effect on the steel plate member 2 in the vertical direction, so it will not affect the seismic isolation performance of the seismic isolation bearing 13. In addition, in order to keep the position of the partition net member 7 relatively stable on the first fixing member 3 and the second fixing member 4, in this embodiment, flexible support members 43 are provided on both the first fixing member 3 and the second fixing member 4, and the flexible support members 43 are used to fill and support the end positions of the partition net member 7, so that the partition net member 7 can achieve a more stable supporting effect.

[0040] It can be imagined that in the above embodiment, arranging the partition net member 7 below the steel plate member 2 to support it also has the following beneficial effects. In the actual structure of the seismic isolation trench 8, sundries and garbage often fall from the gaps of the steel plate member 2 into the seismic isolation trench 8. The partition net member 7 can not only achieve a good supporting effect, but also block part of the garbage to prevent it from falling below the seismic isolation trench 8. In addition, when performing construction and maintenance on the inside of the seismic isolation trench 8 later, it is only necessary to remove the partition net member 7 from the two flexible support members 43, so it will not affect the convenience of later maintenance.

[0041] Specifically, during installation, the second fixing member 4 is installed first, and then the first fixing member 3 is installed. Specifically, when installing the first fixing member 3, first, the opening of the U-shaped mounting member 31 is downward and clamped at the air shaft opening 141, and its position is fixed by the first bolt 32. Then, corresponding to the position of the second fixing member 4, the position of the first mounting member 33 on the U-shaped mounting member 31 is adjusted. After the adjustment is completed, the vertical portion 332 is fixed at the corresponding threaded mounting hole 311 by the second bolt 34. One of the flexible support members 43 is installed in the first mounting groove 331a of the horizontal portion 331.

[0042] When installing the second fixing member 4, first install the right-angle fixing portion 41 at the corner of the upper end of the upper wall 11, and then install the other flexible support member 43 on the receiving portion 42. After the two flexible support members 43 are installed, the partition net member 7 can be installed between the two flexible support members 43. Among them, the two straight edges of the right-angle fixing portion 41 are perpendicular to each other. When installing, in order to ensure the installation strength, both of its right-angle edges can be fixedly installed on the upper wall 11.

[0043] When fixing one end of the steel plate member 2, first install the installation protrusion 211 on the end of the steel plate member 2 corresponding to the sinking groove 331b, and then insert one end of a plurality of third bolts 25 into a plurality of fixing holes 212, and fix one end of the steel plate member 2 on the horizontal portion 331 through the plurality of third bolts 25.

[0044] At the same time, in order to prevent rainwater from entering the isolation trench 8 as much as possible, the vertical portion 332 and one end of the steel plate member 2 are filled with a waterproof sealing material 5, and a sealing gasket 6 is provided between the right-angle fixing portion 41 and the upper wall 11.

[0045] In order to divert rainwater on rainy days, in this embodiment, the steel plate member 2 and the partition net member 7 are installed obliquely. Specifically, when installing, the vertical height of the first mounting member 33 is higher than that of the second fixing member 4, and the upper end surfaces of the horizontal portion 331 and the receiving portion 42 are both obliquely arranged. The corresponding partition net member 7 is installed at a certain angle at this time. The installation protrusion 211 and the plurality of fixing holes 212 are both provided at one end of the inclined portion 21. After fixing one end of the inclined portion 21, the inclined portion 21 is located above the partition net member 7, and the corresponding flat portion 22 is located above the right-angle fixing portion 41. The setting of the inclined portion 21 can accelerate the flow of rainwater to the outside of the steel plate member 2 when it rains, thereby preventing rainwater from accumulating on the steel plate member 2 and avoiding rainwater from entering the isolation trench 8 to a certain extent. In addition, a shielding portion 23 is provided at one end of the flat portion 22 away from the inclined portion 21. The lower end of the shielding portion 23 is attached to the upper end surface of the upper wall 11, and it has a certain shielding effect to prevent sundries from entering the inside of the steel plate member 2.

[0046] In addition, a plurality of anti-slip protrusions 24 are provided on the upward end surfaces of the inclined portion 21 and the flat portion 22, so that pedestrians will not easily slip when walking on the steel plate member 2, and a louver structure 142 is designed at the air shaft opening 141 to protect the air shaft structure 14 from rain.

[0047] The above are only the preferred embodiments of the present utility model, and do not thereby limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
