Shockproof seismic device

 

(57) Abstract:

The invention relates to a gearless mechanical devices, absorbing the shock of an earthquake and can be used in the construction of buildings and structures in seismic areas. The mechanism shockproof device consists of a cylinder 1 with flanges 2 and 3. Inside the cylinder 1 is solid cast iron piston 4. At some distance from the ends of the cylinder 1 drilled vent suction holes 5. Dust in the cylinder 1 is provided the protective cover 6, which is installed with a gap 7 between the cylinder 1. Shockproof device is used as an intermediate support. Kinematic energy in seismic impact is consumed due to the motion of the piston 4 in the cavity of the cylinder 1 when alternate suction and release the air from the cavity 4 of the cylinder 1. 3 C.p. f-crystals, 1 Il.

The invention relates to the construction and can be used to protect buildings and structures from damage during the earthquake.

The closest analogue is shockproof seismic device, comprising a cylinder (see application Germany N 1634364, CL E 02 D 27/34, 1972).

A disadvantage of the known device is the lack of efficiency and seismic effects.

The figure schematically depicted in the context of seismic shock device.

Shockproof device comprises a cylinder 1 with flanges 2 and 3. Inside the cylinder is a piston 4, the top and bottom circumference of the cylinder 1 at udalenie from the flanges 2, 3 drilled vent suction holes 5. To prevent the ingress of dust into the cylinder 1 has a protective casing 6 that is located with a gap 7 between the cylinder 1.

The device operates as follows.

A powerful impetus through the bearing surface of the flange 2 is closely adjacent to the piston 4, which with great speed goes up, displacing the air from the cylinder 1 through the upper openings 5 and sucking it through the lower holes 5.

When the piston reaches the top of the holes 5, cutoff occurs air outlet from the cavity of the cylinder 1 and the compressed air in the upper chamber of the cylinder 1 is left, and then dropped down.

Now will be the same, only air will be displaced from the lower cavity of the cylinder 1, then shrink, and passivates in the upper cavity of the cylinder 1.

This will continue until used kinetic energy.

1. FR is rsen, made of solid cast iron disc and the cylinder wall is formed by blowing-suction holes.

2. The device under item 1, characterized in that the blowing-suction holes are drilled evenly spaced around the circumference.

3. The device under item 1, characterized in that the blowing-suction holes formed at a distance from the ends of the cylinder.

4. The device under item 1, characterized in that it is provided with a casing installed with a clearance around the cylinder.
