Description
Technical Field
The invention relates to the technical field of building earthquake resistance, in particular to a building shock absorption and energy dissipation method based on elastic potential energy conversion.
Background
An earthquake-proof joint, also known as a quakeproof joint, is a structural joint designed between adjacent building units when a building is designed and built, and is a gap preset to reduce or prevent collision of the adjacent building structural units caused by earthquake action. In order to prevent the house from being damaged by earthquake, the house building is divided into a plurality of independent parts with simple shapes and uniform structural rigidity by using the shockproof joints.
However, after the earthquake-resistant joint divides the building into single building units, the horizontal area of each single building unit is small, the stability of each single building unit is poor, the swing-resistant effect is reduced, and especially for some high-rise buildings, the upper end of each single building unit can generate large swing vibration in some microminiature earthquakes and windy weather, so that the normal use of the building is greatly influenced. Meanwhile, when the building units are high in height, the single building unit is too large in swing amplitude, and collision between the adjacent building units is easily caused to cause damage.
To solve this problem, there are some prior art patents for shock absorbing devices to be installed between the anti-seismic seams. For example, CN201920488207.6 discloses a shockproof joint anti-collision device for building construction; CN201920880239.0 discloses an anti-collision device for quakeproof joints of building construction; CN201721077895.4 discloses a composite building anti-vibration joint device. The devices of these patented technologies can be installed between adjacent shock absorbing and shock resistant seams and are used to reduce the impact of an earthquake or hurricane on the swinging of the upper end of the building.
However, these prior patents also have the following drawbacks: all rely on the spring member who fixedly sets up about the horizontal direction to realize shock attenuation and buffering among 1 device, during the device was used, the spring is compressed and extension repeatedly at pressure and pulling force on the horizontal direction, its self also repeatedly, and the spring also can directly produce the reverse effort of bounce-back on the horizontal direction after atress compression and tensile self. Therefore, the acting force and the reacting force of the spring are converted back and forth in the horizontal direction, so that the actual damping effect of the device is poor, and the effect of reducing the left and right swinging of the building is poor. 2 the function effect of antidetonation seam self is the influence to adjacent building unit when avoiding single building unit to collapse and fall, and current antidetonation seam damping device's structure is fixed mounting between adjacent building, so when single building unit collapses and falls, can draw the effect through damping device and act on adjacent building unit, so greatly reduced the function effect and the meaning of antidetonation seam self.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a building damping and energy dissipation method based on elastic potential energy conversion, which can better prevent the left and right swinging of a building and improve the damping and buffering effects; and further enables it to reduce the impact on the functional action of the seismic joint itself.
In order to solve the technical problems, the invention adopts the following technical scheme:
a building shock absorption and energy dissipation method based on elastic potential energy conversion is characterized in that the force transmission direction between two adjacent buildings on the left side and the right side of a shock resistant joint is changed by a connecting rod sliding block, the kinetic energy of any building swinging left and right in the horizontal direction is converted into the elastic potential energy of springs in other directions, and energy dissipation and shock absorption are achieved.
Therefore, the invention can convert the stress direction by means of the connecting rod and the sliding block, convert the horizontal swing of the building into the elastic potential energy of the spring in the vertical direction, further convert the elastic potential energy into internal energy consumption and dissipate the internal energy consumption, and realize the buffering, shock absorption and energy dissipation. Simultaneously because vertical damping spring's reaction force is direct to vertical direction, can directly not produce and drive the building along the horizontal direction and last the reaction effect of horizontal hunting. Can be more favorable to preventing the building horizontal hunting, improve the shock attenuation buffering effect.
The method is realized by means of the following shock absorption device for the anti-seismic joints of the buildings, the shock absorption device for the anti-seismic joints of the buildings comprises two bases which are arranged on the side walls of the buildings on two sides of the adjacent sides of two adjacent buildings, a horizontal shock absorption spring which is horizontally arranged is arranged between the two bases, the shock absorption device also comprises a vertical shock absorption spring which is vertically arranged, and the bases are in transmission connection with the vertical shock absorption spring through connecting rods which are obliquely arranged. The transmission connection means that when the upper end of the building swings left and right, the base can drive the vertical damping spring to compress or extend through the connecting rod.
Like this, after having add vertical damping spring, when the device both sides building unit horizontal hunting, can drive vertical damping spring through the connecting rod and compress or stretch out along vertical direction, turn into vertical damping spring elastic potential energy with kinetic energy and further turn into the interior energy consumption and scatter, realize buffering shock attenuation energy dissipation. Simultaneously because vertical damping spring's reaction force is direct to vertical direction, can directly not produce and drive the building along the horizontal direction and last the reaction effect of horizontal hunting. Can be more favorable to preventing the building horizontal hunting, improve the shock attenuation buffering effect.
Further, still including the horizontal damping spring that the level set up, slide cartridge and slide bar, slide cartridge has a bottom and an open end, the one end of slide bar is connected on a base, the cooperation of pegging graft is in the open end of slide cartridge and inserts a section of distance of slide cartridge slidable the other end, the slide cartridge bottom is connected on another base, horizontal damping spring is coil spring and installs inside slide cartridge, horizontal damping spring one end and slide cartridge bottom are fixed to be continuous, the other end and slide bar end fixing link to each other.
Therefore, after the device is used, when the building units swing in the process of earthquake or hurricane, two adjacent building units swing towards the mutual away direction, the sliding rod slides in the sliding cylinder and pulls the horizontal damping spring to be in a stretching state, the swinging distance is reduced by means of the tension of the horizontal damping spring, and meanwhile, the horizontal damping spring deforms in a telescopic mode to convert part of kinetic energy into internal energy to be released. When adjacent building unit toward the direction swing of drawing close each other, the slide bar slides and compresses horizontal damping spring in the slide cartridge, relies on horizontal damping spring's compression to realize the buffering shock attenuation, reduces the trend that adjacent building drawn close, and horizontal damping spring compression deformation turns into partial kinetic energy to internal energy release simultaneously. In the process, the horizontal damping spring is arranged in the sliding barrel, so that the spring can be protected, and the spring can be in contact friction with the inside of the sliding barrel when being compressed and deformed, so that kinetic energy can be better converted into internal energy and transmitted to the outside of the sliding barrel to be released; improve buffering shock attenuation effect.

Simultaneously this structure makes and draws close each other between the adjacent building more, and the friction damping coefficient that horizontal damping spring week side and slide cartridge inner wall contact produced is bigger, can turn into internal energy with kinetic energy more, so can be favorable to more assisting to avoid building upper end to bump.
As optimization, the inner wall of the sliding barrel is provided with a groove along the length direction.
Like this, the recess supplies horizontal damping spring to receive the extrusion shrink back, can reserve the space that supplies the spring outside expansion to warp at the slide cartridge inner wall when spring periphery and slide cartridge inner wall contact, avoids the spring to be blocked and dies, guarantees that the spring can kick-back smoothly. Furthermore, the grooves are uniformly arranged along the circumferential direction, so that the contact stress between the grooves and the outer periphery of the spring is more balanced and stable.
Preferably, the end part of the sliding rod, which is positioned in the sliding cylinder, is provided with a piston, the sliding rod integrally forms a piston rod, a dynamic seal matching structure is arranged between the opening end of the sliding cylinder and the sliding rod, lubricating liquid is arranged in the sliding cylinder, and the piston is provided with a liquid passing hole.

When the piston rod is implemented, the lubricating liquid in the sliding cylinder is not filled and a section of space is reserved, so that the piston rod can be better inserted. In addition, if the inner wall of the sliding cylinder is provided with the groove, the function of the liquid passing hole can be realized by the groove without arranging the liquid passing hole on the piston. The groove is used for realizing the flowing of the lubricating oil, and the lubricating effect of the lubricating oil on the sliding of the piston in the sliding cylinder can be enhanced. Based on the optimized inner cavity structure of the horizontal damping spring, the invention also discloses a damping and energy-consuming method of the building anti-seismic joint damping device, namely, lubricating liquid is arranged in the inner cavity of the damping device for mounting the damping spring, and kinetic energy is better converted into internal energy and heat and is dissipated by depending on the flowing of the lubricating liquid; and can further rely on lubricated liquid to improve damping spring periphery lubricated effect for damping spring can be compressed under periphery and inner chamber wall contact state, converts kinetic energy into internal energy heat and dissipates through the friction of damping spring and inner chamber wall better.

Although part of the reaction force can be transmitted to the base through the sliding block and the connecting rod, the kinetic energy can be further converted into the internal energy through the friction action of the middle sliding block and the vertical rod, and the reaction force effect is reduced. Meanwhile, the vertical damping springs and the horizontal damping springs are combined, so that a multidimensional three-dimensional buffering damping effect can be formed, and the effects of damping and energy dissipation can be better achieved.
