Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, a piping support apparatus A having an earthquake-proof and seismic isolation function according to the present invention includes a first body 10, a spring 20, a flow bar 30, a second body (not shown) 40).

The first body 10 has an opening 11 extending in a longitudinal direction at a central portion thereof, and a spiral 12 is formed on an outer circumferential surface of one end and a flange 13 is formed on an outer circumferential surface of the other end.

In the first body 10, the flange 13 is fixed to the ceiling 100 or the wall 200 so that the first body 10 is installed on the ceiling 100 or the wall 200.

At this time, the flange 13 may be formed in a circular shape as shown in FIG. 4 as well as a circular shape.

Here, the circular flange 13 has a plurality of bolt through-holes 13a arranged at equal intervals in four chambers, and the rectangular flange 13 has a plurality of bolt through holes The ceiling 100 or the wall 200 may be fastened to the tip of a bolt (not shown) passing through the bolt through-hole 13a so that the flange 13 is inserted into the ceiling 100 or And is fixed to the wall surface 200.

16, an anchor 70 embedded in the ceiling 100 or the wall surface 200 can pass through the bolt through-hole 13a, and the bolt through-hole 13a, The flange 13 is fixed to the ceiling 100 or the wall surface 200 by fastening the nut 71 to the tip of the anchor 70 penetrating the ceiling 100.

Since the anchor 71 embedded in the ceiling 100 or the wall surface 200 is bent in the shape of a letter 'A', the embedded state is strengthened. Therefore, The fixing of the flange 13 becomes more stable.

A pad 73 made of an elastic material is inserted between the flange 31 and the supporting plate 72 supporting the anchor 70 embedded in the ceiling 100 or the wall surface 200, It is possible to disperse, absorb, and disappear the impact when an earthquake occurs.

The outer peripheral surface of the lower end of the first body 10 is formed in a polygonal shape.

Therefore, it is easy to engage with the second body 40 by turning around the outer periphery formed in the polygonal shape of the lower end of the first body 10 with a tool such as a wrench (not shown in the drawings).

Meanwhile, the first body 10 may be formed of any conventional material as long as its durability can be stabilized, for example, metal or synthetic resin.

The spring (20) is inserted into the opening (11) of the first body (10).

Such a spring 20 may be any ordinary one as long as it is contracted as an external force is applied and can be stretched from a contracted state as the external force is released.

At this time, the springs 20 may be formed as a plurality of springs 20 as shown in FIG. 17, and may be installed vertically and separately in the opening 11.

The upward movement of the flow bar 30 is facilitated by the elastic force of the lower spring 20 and the upward movement of the flow bar 30 due to the elastic force of the upper spring 20, Is smooth.

Meanwhile, when the spring 20 is installed so as to be separated up and down, the supporting portion 43 of the second body 40 described below may not be formed as a curved surface.

That is, when the spring 20 is vertically and separately installed, the seating portion 31 of the flow bar 30 is separated from the supporting portion 43 by the lower spring 20, 43, the supporting portion 43 of the second body 40 may not be formed as a curved surface.

A curved seating part 31 is formed at one end of the moving bar 30 facing the spring 20.

In such a flow bar 30, the seating part 31 may be formed in a semi-spherical shape as shown in FIG. 5 or an elliptical shape as shown in FIG. 17 in addition to a spherical shape.

The diameter of the seating part 31 is larger than the diameter of the spring 20 so that the seating part 31 is prevented from being inserted into the spring 20, The flow bar 30 is elastically supported.

The flow bar 30 may further include a diaphragm 32 disposed between the seat portion 31 and the spring 20 as shown in FIG.

At this time, the diaphragm 32 is formed to have a larger diameter than the diameter of the spring 20, thereby preventing the seating portion 31 from being inserted into the spring 20 by the diaphragm 32.

The diaphragm 32 has a protrusion 32a which is inserted into the spring 20 at the center of one side so that the diaphragm 32 can be easily positioned by the protrusion 32a, (32) is correctly seated in the center of the spring (20).

11 or 12, one end of the fluid bar 30 on the opposite side of the seating part 31 may engage with the clamp 50 or the section steel 60.

Accordingly, the pipe 300 is supported by the flow bar 30 by wrapping the pipe 300 with the clamp 50, or the pipe 300 is placed on the upper surface of the pipe 60, The pipe 300 is supported by the flow bar 30 as the U 'bolt 61 is fastened.

At this time, the flow bar 30 may have a link portion 33 having a through hole 33a at one end on the opposite side of the seating portion 31. [

Therefore, a through hole (not shown) of the link portion 51 provided in the through hole 33a of the link portion 33 and the clamp 50 or a link portion (not shown in the drawing) provided in the shape steel 60 (Not shown) and a nut (not shown) are fastened to each other so that the coupling of the clamp 50 or the section steel 60 to the flow bar 30 is completed, It is possible.

Here, the link portions 33 may be formed as a unit, but when the pair of link portions 33 are formed as shown in FIG. 13, the coupling state with the clamp 50 or the section steel 60 is more stable.

A spiral 34 may be formed at one end of the flow bar 30 on the opposite side of the seating part 31.

One end of the flow bar 30 on which the spiral 34 is formed is inserted into a through hole provided in the clamp 50 or a through hole provided in the section steel 60 The clamp 50 or the section steel 60 can be coupled to the flow bar 30 by fastening a nut (not shown) to the spiral 34.

A plurality of, for example, one pair of the flow bars 30 may be disposed with an interval when the section bars 60 are coupled to the flow bars 30, And the one end of the other of the flow bars 30 is fixed to the other end of the shape bar 60 so that the flow bar 30 is fixed to the one end of the shape bar 60 Stable coupling is possible.

The flow bar 30 may be formed in a wire shape as shown in FIG.

The flow bar 30 in the form of a wire reacts more sensitively in response to an impact at the time of an earthquake, so that the flow of the flow bar 30 becomes more smooth.

At this time, the flow bar 30 in the form of a wire can be engaged with the clamp 30 or the section steel 60 by binding one end thereof in a ring shape.

The flow bar 30 may be formed of any conventional material as long as its durability can be stabilized, for example, metal or synthetic resin.

The second body 40 has an opening 41 extending in the longitudinal direction at a central portion thereof and a spiral 42 engaged with the spiral 12 of the first body 10 is formed on an inner circumferential surface of one end And a curved support portion 43 is formed on the inner peripheral surface of the other end.

In the second body 40, the supporting portion 43 is formed to have the same curvature as the seating portion 31 of the flow bar 30, and the seating portion 31 Backward, leftward and rightward in a state in which it is in close contact with the support portion 43.

The support portion 43 of the second body 40 may have a downward inclined portion 43a whose diameter gradually increases toward the lower end.

Therefore, when the flow bar 30 flows in the second body 40, the flow bar 30 can flow further outwardly by the inclined section 43a, It is possible to expand the flow width.

The support portion 43 of the second body 40 may have a linear section 43b which is in close contact with the outer circumferential surface of the flow bar 30 at one side of the lower end.

The straight section 43b is formed in the longitudinal direction of the movable bar 30 extending in the lateral direction when the supporting device A for supporting the pipeline 300 having the seismic and seismic isolation function according to the present invention is installed horizontally on the wall surface 200. [ Since the lower end of the outer surface is supported to prevent sagging of the flow bar 30, sagging of the pipe 300 due to sagging of the flow bar 30 is normally prevented.

The outer circumference of the upper end of the second body 40 is formed in a polygonal shape.

Therefore, it is easy to engage with the first body 10 by rotating the outer circumference of the upper end of the second body 40 with a tool such as a wrench.

The second body 40 may be formed of any conventional material as long as its durability can be stabilized, for example, metal or synthetic resin.
