Abstract

A fastening-type pipe supporting apparatus capable of supporting a curved pipe against loads acting on a curved portion of the pipe via clamps having curved surfaces and being easily attached to and detached from the curved portion of the pipe. The fastening-type pipe supporting apparatus includes: a first clamp having a semicircular cross-sectional shape and a curved surface with a curvature to surround the curved portion of a pipe; a second clamp having a semicircular cross-sectional shape and a curved surface with a curvature to surround the curved portion of the pipe, the second clamp being coupled to the first clamp; a connection bolt coupling the first clamp with the second clamp; and a washer placed around the connection bolt.

Claims

1. A fastening-type pipe supporting apparatus for supporting a curved pipe against loads acting on a curved portion of the pipe, the fastening-type pipe supporting apparatus comprising:

a first clamp having a curved surface with a curvature, a first curved lateral edge and a second curved lateral edge;

wherein the curved surface of the first clamp has comprises a semicircular cross-sectional shape, wherein the first clamp comprises first and second curved connection portions extending outwardly from the first and second curved lateral edges, respectively, wherein each of the first and second curved connection portions comprises a concave surface and a convex surface extending the full length of the first clamp, and each of the first and second curved connection portions comprise a plurality of connection holes;

a second clamp having a curved surface with a curvature, a third curved lateral edge, and a fourth curved lateral edge;

wherein the curved surface of the second clamp has a semicircular cross-sectional shape, wherein the second clamp comprises third and fourth curved connection portions extending outwardly from the third and fourth curved lateral edges, respectively, wherein each of third and fourth curved connection portions comprises a concave surface and a convex surface extending the full length of the second clamp, and wherein each of the third and fourth curved connection portions comprises a plurality of connection holes;

wherein the first clamp is smaller than the second clamp;

at least one connection bolt coupling the first clamp with the second clamp;

wherein the first clamp and the second clamp coupled by the at least one connection bolt is configured to surround the curved portion of the pipe; and

at least one washer placed around the at least one connection bolt,

wherein a side of the at least one washer is curved with a curvature and another side of the at least one washer is flat,

wherein the side of the at least one washer being curved is in contact with one of the connection portions.

2. The fastening-type pipe supporting apparatus of claim 1, further comprising a supporting part coupled to the at least one connection bolt for supporting the curved portion of the pipe.

3. The fastening-type pipe supporting apparatus of claim 1, wherein a stanchion, or lug is provided on the curved surface of the first clamp or the curved surface of the second clamp for supporting the curved portion of the pipe.
