Abstract
A supporting device for non-averaged force in a pipeline comprised of a frame that is fixed to a supporting portion and a fixing mechanism for fixing a pipe body to the frame, wherein wedge bodies capable of blocking movements of the pipe body in a pipe axial direction with respect to the frame are provided when being pressed against an outer surface of the pipe body through pressing force acting from the frame towards the pipe body.
Claims11
A supporting device for non-averaged force in a pipeline comprising:
- a frame comprising:
- i) a pipe supporting portion for encircling a pipe body inserted thereto in an axial direction of the pipe supporting portion, said pipe supporting portion having an inner circumferential surface being divided into first and second portions in its circumferential direction,
- ii) a mounting seat portion configured to be fixed to a supporting planar base, said mounting seat portion having a width perpendicular to the axial direction of the pipe supporting portion, which is greater than an inner diameter of the pipe supporting portion, said mounting seat portion having a length in the axial direction of the pipe supporting portion, which is greater than a thickness of the pipe supporting portion in its axial direction, said pipe supporting portion extending vertically from the mounting seat portion, and
- iii) a rib attached to the mounting seat portion, extending vertically from the mounting seat portion and extending in the axial direction of the pipe supporting portion, and connected to the pipe supporting portion for supporting the pipe supporting portion, wherein the mounting seat portion, the pipe supporting portion, and the rib are rigidly formed;
- and
- a fixing mechanism for fixing the pipe body to the pipe supporting portion, said fixing mechanism comprising a coupling member for coupling the first and second portions of the pipe supporting portion to encircle the pipe body, and at least sharp edges or wedges disposed in the inner surface of the pipe supporting portion and movable inwardly with respect to the inner surface of the pipe supporting portion to contact and unmovably fix the pipe body to the pipe supporting portion, wherein an interior between the inner surface of the pipe supporting portion with the edges or wedges and an outer surface of the pipe body is sealable for anti-corrosive effects by closing circumferential clearances at front and rear ends of the interior with a caulking material.
