The brake block 122 of corresponding first plugboard in position 123 ', forms Fig. 4 expanded views, this fit system can form quick startup
Pattern is conducive to the first plugboard and the opposite startup slided of the second plugboard
In order to enable special transition piece has dust-proof effect, make between the first plate and the second plate and the second plate third plate
It is packaged with seal sleeve 6, forms a kind of dustless structure.
Can be formed when earthquake occurs, between the first plugboard and the second plugboard it is a kind of opposite slide, at the initial stage of slip,
Brake block on first plugboard 12 can and the second plugboard on smooth position cooperation with reference to figure 4, frictional force during startup compared with
It is small, can realize quick startup, avoid it is stuck, simultaneously as between above-mentioned the first plugboard and the second plugboard, Yi Ji
It is multigroup arranged in a crossed manner between three plugboards and the 4th plugboard, rigidity, stability and tilting moment are all fine, and safety will
It asks, after first, second plugboard starts and slides, and then, the brake block on first, second plugboard starts to contact, and is formed
Sliding friction, due to just starting, the brake block contact area on two plugboards is smaller, by friction formula it is found that adding at this time
Speed is larger, and opposite slide is still within boost phase, after brake block overlapping is more than half, since the frictional force between brake block increases
Greatly, can be there are one speed-down action, and a large amount of earthquake energy after the brake block on equivalent plugboard completely disengages, is completed
Speed-down action, during due to earthquake, the amplitude of horizontal direction is generally large, into next cycle, in the process, ensures both sides
Plugboard between be used in acceleration repeatedly and moderating process, wherein acceleration a forms pulse pattern, positive and negative back and forth to cut
It changes, a big seismic amplitude can be divided into multiple small transition piece Self-oscillation amplitudes, and consume the energy of earthquake zone.Together
When the high amplitude by a narrow margin of earthquake is acted, be switched to the frequency low-amplitude action of building, be conducive to the self-protection of building.
Under high wind effect, steel tower upper member can wave, and under the action of transition piece, micro horizontal movement occurs,
And overcome the effect of brake block therein, it brakes, the effective amplitude and frequency for changing wind load improves anti seismic efficiency.
The presence of above-mentioned cylindrical roller can ensure the smooth of startup, and avoid between low temperature plugboard and the first plate
Frictional dissipation, while there is guiding role, it prevents that stuck phenomenon occurs between two adjacent plates.
The above-described embodiments are merely illustrative of preferred embodiments of the present invention, not to the model of the present invention
It encloses and is defined, under the premise of design spirit of the present invention is not departed from, various changes of the relevant technical staff in the field to the present invention
Shape and improvement should all expand as determined by claims of the present invention in protection domain.
