Description
Technical Field
[0001] The utility model relates to the technical field of earthquake resistance of underground buildings, in particular to an earthquake-resistant supporting structure for underground engineering. Background Art
[0002] Underground engineering refers to underground civil engineering projects built deep below the ground for the development and utilization of underground space resources. Since they need to withstand pressure from the upper layer, seismic support structures are needed to support underground engineering during the construction process to facilitate the pouring of concrete and beams and columns during construction. Generally, seismic support structures are divided into temporary support and permanent support. Temporary support needs to be removed after the concrete and beams and columns are poured and formed, while permanent support does not need to be removed as part of the underground engineering construction, and its role is similar to that of a support beam.
[0003] During underground engineering construction, in order to adapt to the compression of underground soil on the building, the building itself will tend to shift laterally. In order to adapt to the vibration of vehicles passing through the building, it is also necessary to carry out seismic design between different levels of the building. Based on this, an underground engineering seismic support structure is proposed to solve the above problems. Utility Model Content

[0023] like Figures 1 to 6As shown, an underground engineering seismic support structure is shown, which includes a bottom mounting seat 1, a first guide rail 4 is installed in the middle of the top surface of the bottom mounting seat 1, and sliding blocks 2 are slidably installed at both ends inside the first guide rail 4, a damper 3 is installed between the two sliding blocks 2, and the two are located on both sides of the first guide rail 4, a support plate 12 is installed on the top of the bottom mounting seat 1, and push rods 13 are rotatably installed on both sides of the middle of the bottom surface of the support plate 12, and the bottom ends of the two are rotatably connected to the two sliding blocks 2, the length of the support plate 12 is greater than the length of the bottom mounting seat 1, rubber springs 7 are installed at the four corners of the bottom surface of the support plate 12 and the four corners of the top surface of the bottom mounting seat 1, two second guide rails 11 are installed on the top surface of the support plate 12, and support frames 8 are slidably installed inside the two, and a third guide rail 9 placed perpendicular to the second guide rail 11 is installed on the top surface of the support frame 8, and a top mounting seat 10 is installed between the two third guide rails 9, and the length of the second guide rail 11 is the same as that of the third guide rail 9.
[0024] The four corners of the bottom surface of the bottom mounting seat 1 and the four corners of the top surface of the top mounting seat 10 are provided with raised parts. As an optional technical solution of the present invention, this facilitates the raised parts to be directly docked and connected to the external building. At the same time, in order to ensure the stability of the connection, embedded parts can be set at the docking position of the building. During installation, the connection is fixed by bolts to ensure the structural stability of the connection.
[0025] Two limit rings 6 are installed at both ends of the bottom mounting seat 1, and limit columns 14 that cooperate with the limit rings 6 are installed on both sides of the bottom surface of the support plate 12. As an optional technical solution of the present invention, this facilitates guiding the up and down movement of the support plate 12, while ensuring that the support plate 12 remains relatively horizontal during the movement, which facilitates uniform compression of the four rubber springs 7.
[0026] A plurality of limit blocks 5 are installed at the four corners of the top surface of the bottom mounting seat 1 and the four corners of the bottom surface of the support plate 12. Each group of four limit blocks 5 is clamped with the two ends of the rubber spring 7 respectively.

[0027] The adjacent sides of the two sliding blocks 2 are installed with card columns, and the external sleeves of the two card columns are installed with buffer springs 15. As an optional technical solution of the present invention, this facilitates providing an installation position for the buffer spring 15. At the same time, the buffer spring 15 is placed inside the first guide rail 4, which makes it easier to limit the buffer spring 15 and prevent the buffer spring 15 from collapsing.
[0028] Baffles 16 are installed at both ends of the two second guide rails 11 and both ends of the two third guide rails 9.

[0029] The underground engineering seismic support structure requires the following steps when used:
[0030] 1) The vibration of the top building is transmitted to the four rubber springs 7 through the top mounting base 10 and the support plate 12;
[0031] 2) The support plate 12 and the bottom mounting base 1 move relative to each other, and the two sliding blocks 2 are driven to slide by the two push rods 13;
[0032] 3) The two sliding blocks 2 compress the two dampers 3 and the buffer spring 15 or pull the two dampers 3;
[0033] 4) The two dampers 3 convert the kinetic energy into heat energy and dissipate it, thereby reducing shock.
[0034] To sum up, when the user uses it, by setting the bottom mounting seat 1 and the support plate 12, rubber springs 7 are installed at the four corners of the adjacent surfaces of the two, and the first guide rail 4 is installed in the middle of the top surface of the bottom mounting seat 1, and two sliding blocks 2 are installed inside it, and a damper 3 and a buffer spring 15 are installed between the two. At the same time, a push rod 13 is installed on the top surface of the two sliding blocks 2, and the top ends of the two are rotatably connected to the support plate 12. The top mounting seat 10 is connected to the top building, and the vibration of the top building is transmitted to the four rubber springs 7 through the top mounting seat 10 and the support plate 12. At the same time, the push rod 13 drives the two sliding blocks 2 to slide against each other and tensions or compresses the two dampers 3, thereby achieving buffering and absorption of external vibrations, and preventing vibrations from being transmitted to the bottom mounting seat 1, thereby effectively solving the problems existing in the prior art. The problem is solved by setting a bottom mounting seat 1 and a support plate 12, and at the same time, limit rings 6 are installed at both ends of the support plate 12, and limit columns 14 are installed on both sides of the bottom surface of the bottom mounting seat 1, and the limit columns 14 are slidably connected to the limit rings 6, so as to facilitate the guiding of the up and down movement of the support plate 12, and ensure that the four rubber springs 7 are evenly compressed, and finally, two second guide rails 11 and two third guide rails 9 are set, and the two are placed vertically, and at the same time, the support frame 8 is slidably connected to the two second guide rails 11, and the top mounting seat 10 is slidably connected to the two third guide rails 9. When there is a relative movement trend between the top building and the bottom building, the support frame 8 and the two second guide rails 11, and the top mounting seat 10 and the two third guide rails 9 slide relative to each other, so that the top building and the bottom building are relatively displaced to ensure the overall safety.
