Abstract
The invention discloses a shock absorber for a building, which comprises a shell, a screw rod, a flywheel, a planetary steel ball stepless speed change device, a nut and a shell support, wherein the screw rod is fixed on a foundation, the screw rod and the nut form a screw pair, the nut is connected with the flywheel, the flywheel is connected with the planetary steel ball stepless speed change device, the flywheel is arranged at the shell support, and the shell is fixedly connected with the building. Through screw and nut transmission, the external impact energy borne by the building is converted into the kinetic energy of the planetary steel ball stepless speed change device to be released, instead of the traditional damping mode, the energy is absorbed through a damper, and the use and maintenance cost of the building damping system is reduced.
Description
Technical Field
The invention relates to a shock absorption structure, in particular to a shock absorber for buildings.
Background
At present, the shock absorption measure in the aspect of building is that a structural engineer uses the automobile shock absorption concept in a building structure, the material is generally steel with better ductility or a large spring and a hydraulic system, and the core idea is as follows: the weak person is damaged to protect the strong person, the energy brought to the building by the earthquake is digested by the shock absorber, and therefore the tearing effect of external force such as the earthquake and the like on the building is reduced, but a large shock absorption structure is needed in high-rise and super high-rise buildings, and the high-rise and super high-rise buildings are greatly influenced by wind force, need to be replaced frequently, and are high in use cost. Therefore, the building shock absorber needs to be developed, and has long service life and low use cost.
Disclosure of Invention
The purpose of the invention is as follows: aiming at the problems, the defects are overcome, and the requirement of low building damping maintenance cost is met.
The technical scheme is as follows: a shock absorber for buildings comprises a shell, a screw, a flywheel, a planetary steel ball stepless speed change device, a nut and a shell support.
Further, the shock absorber for building still includes the spring, and spring one end is installed in the casing, and the other end is connected with the screw rod.
Further, the shock absorber for buildings also comprises damping oil, and the damping oil is arranged in the shell.
Further, the housing support is a bearing.
Further, the flywheel is connected with the planetary steel ball stepless speed change device through a bolt.
When a building is built, the bottom of the building is provided with a uniform number of building shock absorbers, the screw rods are connected with the foundation, the shell is connected with the building, the screw rods and the nuts form screw pairs, the nuts drive the flywheel to run, and the flywheel drives the planetary steel ball stepless speed change device to move. When a building and a bridge are influenced by strong wind, earthquake and the like, the building can swing, the building can correspondingly bear downward or upward pressure and simultaneously accompany with torsion, the nut of the damping system can move downward or upward along the screw rod, the nut can drive the flywheel to rotate when moving, and the flywheel can drive the planetary steel ball stepless speed change device to move, so that potential energy received by the foundation of the building can be converted into kinetic energy of the planetary steel ball stepless speed change device to be released, and the building, the bridge and the like can be protected. When the external influence factors disappear, the buildings, bridges and the like can still be restored to the initial positions.
The principle of the invention is as follows: through the transmission of the screw rod and the nut, the external impact energy borne by the building is converted into the kinetic energy of the planetary steel ball stepless speed change device to be released, so that the building is protected.
Has the advantages that: compared with the prior art, the invention has the advantages that: according to the invention, through screw and nut transmission, external impact energy borne by a building is converted into kinetic energy of the planetary steel ball stepless speed change device to be released, instead of the traditional damping mode, the energy is absorbed through the damper, and the use and maintenance cost of the building damping system is reduced.
