Detailed description of the invention
Fig. 1 is the structural schematic diagram of civil engineering damping device of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the civil engineering damping device in the present embodiment, including upper shell of column 1, lower shell of column 2, upper 1 He of shell of column
Lower shell of column 2 is circular tube shaped, and end is provided with attachment base, and long through-hole is provided on attachment base as cushion hole.Wherein, upper prop
The length direction of upper cushion hole 4 in section 1 is radial vertical with the circumference of circular hollow section；The length of lower cushion hole 5 on lower shell of column 2
Spend the radially consistent of the circumference of direction and circular hollow section.The attachment base of the attachment base of upper shell of column 1 and lower shell of column 2 is connected by bolt
It connects.
Higher bonding strength in order to obtain, the attachment base of upper shell of column 1 and the attachment base of lower shell of column 2 pass through 8 in embodiment
Bolt connection pair 3 is covered to connect.Certainly, the bonding strength according to required for engineering, it is possible to reduce or increase the number of bolt connection pair 3
Amount, to increase bonding strength or reduce cost.
Bolt connection pair 3 can also use high strength bolt connection pairs 3, to reduce the quantity of connector, mitigate entire dress
The weight set.
It, can be as shown in Figure 1, welding ribbed stiffener between round tube and attachment base in order to improve bonding strength；Ribbed stiffener
Quantity can increase and decrease according to the actual situation, 8 be not limited in figure.The support direction of ribbed stiffener should be vertical with attachment base, with
Obtain better support effect.
In order to improve the shock strength of damping device, the face that the attachment base of the attachment base of upper shell of column 1 and lower shell of column 2 connects is set
Be set to rubbing surface, two rubbing surfaces can be handled by sandblasting (ball), improve the surface hardness of rubbing surface, and generate it is micro- hole with
Improve the coefficient of friction between two rubbing surfaces；Can also be applied afterwards using sandblasting (ball) inorganic zinc rich paint, sandblasting (ball) give birth to afterwards it is red
Rust, wire brush are removed the modes such as floating rust and are handled.
Bolt connection pair 3 includes screw rod, nut and gasket；Between the attachment base of upper shell of column 1 and the attachment base of lower shell of column 2
Add the size that setting friction plate is conveniently adjusted frictional force.
The plate shape that rubs is identical as attachment base or matches；Place corresponding with cushion hole also offers through-hole.Friction plate can
To be also possible to sheet asbestos with latten(-tin), sheet rubber is made, or is combined and be made by above-mentioned different materials；Rubber can also be used
Overlapping is combined or is layered with sheet metal to be made.
Using the damping device in the present embodiment, when encountering the disasters such as earthquake, mud-rock flow, damping mechanism is as described below:
A, when small shake, shearing force suffered by damping device is smaller, and upper shell of column 1 and lower shell of column 2 are resisted by flexible deformation and destroyed
Energy；
B, middle shake and when big shake, as shearing force suffered by damping device increases, the attachment base of upper shell of column 1 and lower shell of column 2
It slides between attachment base, is dissipated failure energy by frictional slip；
C, due to being mutually perpendicular between upper cushion hole 4 and lower cushion hole 5, so that no matter shearing force applies from which direction,
It can be broken into that the component dissipating by sliding along the component of upper cushion hole 4 and lower 5 direction of cushion hole.By adjusting slow
The size of structural limits sliding displacement can be set in the length of punching；To reach dissipation failure energy and reduce the journey of permanent deformation
Degree, convenient for restoring after calamity；
D, by adjusting the size of the quantity of high-strength bolt and diameter control support node anti-pulling capacity；
E, by adjusting the rubbing surface form of attachment base, high-strength bolt quantity and pretightning force size, friction plate material and thickness
Degree changes the size of damping device slip-load and anti-side rigidity.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
