Description

Technical Field

[0001] The present application relates to the technical field of foundation structures, and in particular to a foundation structure for earthquake resistance. Background Art

[0002] The foundation refers to the soil or rock supporting the base of a building. The soil layers serving as the foundation of a building are divided into rock, gravel, sand, silt, clay and artificial fill. There are two types of foundations: natural foundations and artificial foundations (composite foundations). Natural foundations are natural soil layers that do not require human reinforcement, while artificial foundations require human reinforcement. Common ones include stone chip cushion layers, sand cushion layers, mixed lime soil backfill and compaction, etc.

[0003] At present, in artificial foundations, in order to improve the safety level of buildings, foundations with earthquake-resistant functions are generally built. At the bottom of the foundation, multiple earthquake-resistant pillars are generally set up. In addition, some damping rods are also set up to assist in earthquake resistance.

[0004] In the related art, since the damping rod is mostly composed of two telescopically connected rods and the damping oil inside, in order to avoid leakage of the damping oil, a sealing structure is generally arranged between the two telescopic rods. During earthquake resistance, the damping rod performs telescopic movement. When the vibration frequency is high, the damping rod needs to perform high-frequency reciprocating movement. This causes a large amount of heat energy to be generated when the damping rod reciprocates, causing the damping rod to expand as a whole due to heat, which may lead to failure of the seal and leakage of the damping oil. Summary of the invention

[0005] In order to solve the problem that the damping rod currently used in the foundation will generate a large amount of heat energy during high-frequency movement, causing the damping rod to expand due to heat, which in turn causes the seal to fail and the damping oil to leak out, the present application provides a foundation structure for earthquake resistance.

[0006] The present application provides a foundation structure for earthquake resistance using the following technical solutions: A foundation structure for earthquake resistance, comprising: An earthquake-resistant foundation, wherein the upper and lower sides of the earthquake-resistant foundation are connected with fixed seats, a support rod and a telescopic rod are arranged between two upper and lower adjacent fixed seats, and the support rod and the telescopic rod are slidably connected to form an integral structure; A conversion mechanism, which is used to convert linear motion into curved motion, and the conversion mechanism is arranged between the support rod and the telescopic rod, the conversion mechanism includes a supporting seat, a transmission rod, a driving gear, a rack, a sliding cavity and a docking notch, the sliding cavity is arranged in the support rod, and the telescopic rod is slidably connected in the sliding cavity, the supporting seat is fixed on one end of the telescopic rod close to the support rod, the transmission rod is rotatably connected to the supporting seat, the driving gear is coaxially fixed to the transmission rod and is located on one side of the supporting seat, the rack is fixed on the inner wall of the sliding cavity, the docking notch is arranged on one end of the telescopic rod close to the sliding cavity, and the rack is slidably connected in the docking notch, and the driving gear and the rack are meshed with each other; The damping mechanism is used to provide resistance between the support rod and the telescopic rod, and the damping mechanism is arranged in the telescopic rod.

[0007] By adopting the above technical solution, the overall structure composed of the support rod and the telescopic rod is used to assist the earthquake-resistant foundation, and during earthquake resistance, the telescopic rod slides in the support rod, and while sliding, the rack drives the active gear to mesh and link, thereby driving the transmission rod to move, and the linear motion between the support rod and the telescopic rod is converted into curved motion, and the damping mechanism is arranged in the telescopic rod and driven by the transmission rod, thereby avoiding the need for a sealed connection between the support rod and the telescopic rod, so that the support rod and the telescopic rod can avoid the problem of a large amount of heat energy generated by mutual friction and thermal expansion during telescopic motion. By utilizing the setting of the damping mechanism, the original linear motion in the damping rod to squeeze the damping oil for damping and shock absorption is converted into the rotation of the stirring plate and the stirring of the damping oil for damping and shock absorption. As a result, the support rod and the telescopic rod can realize the damping and shock absorption function when they are telescopically moved, and the need for sealing connection between the support rod and the telescopic rod is avoided, thereby effectively increasing the service life and stability of the overall structure.

[0008] Optionally, the conversion mechanism also includes a driven bevel gear and a passive bevel gear, the driven bevel gear is coaxially fixed on the transmission rod, the passive bevel gear is coaxially rotatably connected to one end of the telescopic rod close to the support rod, and is located in the sliding cavity, and the driven bevel gear and the passive bevel gear are meshed with each other, and the damping mechanism is connected to the passive bevel gear.

[0009] By adopting the above technical solution, the rotation of the driven bevel gear drives the meshing linkage of the passive bevel gear, thereby driving the overall linkage of the internal components of the damping mechanism.

[0010] Optionally, the damping mechanism includes a driven rod, a cavity is provided inside the telescopic rod and filled with damping oil, the driven rod is coaxially and rotatably connected in the cavity of the telescopic rod, and one end of the driven rod is coaxially fixed to the passive bevel gear.

[0012] Optionally, the damping mechanism further includes a fixed plate and a stirring plate, one end of the fixed plate is fixed to the driven rod, the stirring plate is fixed to the other end of the fixed plate, and the stirring plate is arranged parallel to the driven rod.
