Abstract

A pipe support is disclosed for restraining a pipe at a position in close proximity to a joint formed by the pipe and a pipe fitting. The pipe support includes a base configured to be secured to a support surface and to interface with an outer surface of the pipe. The pipe support also includes a clamp operable with the base to restrain the pipe. Additionally, the pipe support includes a hinge coupling the base and the clamp, operable to facilitate relative movement between the base and the clamp. The base positions the outer surface of the pipe at a pre-determined distance from the support surface sufficient to at least offset a distance between the outer surface of the pipe and an outer surface of the pipe fitting, thereby preventing a bending load from occurring at the joint upon securing the pipe support to the support surface.

Claims

1. A pipe support for restraining a pipe at a position in close proximity to a joint formed by the pipe and a pipe fitting, the pipe support comprising:

a base configured to be secured to a support surface, the base comprising;

a planar platform having opposite longitudinal ends, a length extending between the opposite longitudinal ends, opposite first and second side edges, and a width extending between the first and second side edges, the platform being configured to engage an outer surface of the pipe;

a first flange extending downward from the first side edge and extending along the length of the platform; and

a second flange extending downward from the second side edge and extending along the length of the platform, the first and second flanges being generally perpendicular to the platform and configured to engage the support surface;

a clamp operable with the base to restrain the pipe; and

a hinge coupling the base and the clamp, and operable to facilitate movement of the clamp relative to the base between open and closed positions,

wherein the first and second flanges position the platform at a pre-determined distance from the support surface sufficient to offset a distance between the outer surface of the pipe and an outer surface of the pipe fitting, thereby preventing a bending load from occurring at the joint upon securing the pipe support to the support surface.

2. The pipe support of claim 1, wherein the first and second flanges are arranged in parallel to support the platform.

3. The pipe support of claim 1, wherein the clamp comprises a fixed end portion attached to the hinge and a free end portion opposite the fixed end portion, the free end portion configured to be secured to a free end portion of the base.

4. The pipe support of claim 1, wherein the clamp comprises a first straight segment attached to the hinge, a curved segment extending from the first straight segment opposite the hinge, and a second straight segment extending from the curved segment opposite the first straight segment, the first and second straight segments being generally parallel.

5. The pipe support of claim 1, wherein the hinge comprises a compliant ligament extending between the base and the clamp, and wherein deflection within the pipe support is substantially confined to the compliant ligament.

6. The pipe support of claim 5, wherein the compliant ligament is configured to limit stress therein sufficient to allow the hinge to undergo at least 10 open and close cycles comprising at least 90 degrees of relative rotation between the clamp and the base.

7. The pipe support of claim 5, wherein the compliant ligament comprises a radius different from a radius of the clamp.

8. The pipe support of claim 1, wherein the hinge comprises a plurality of compliant ligaments.

9. The pipe support of claim 1, wherein the hinge comprises a separable two-piece hinge, and wherein the clamp is attachable to the base upon assembly of the hinge.

10. The pipe support of claim 9, wherein the two-piece hinge comprises a T-bar formed at a fixed end portion of the clamp, and a slot formed at a fixed end portion of the base, the T-bar being insertable into the slot to assemble the hinge.

11. The pipe support of claim 9, wherein the slot comprises a T-slot.

12. The pipe support of claim 4, wherein the clamp comprises a flared edge configured to prevent an edge of the clamp from contacting the pipe, the flared edge including a flange extending along a length of the curved segment.

13. The pipe support of claim 3, the clamp further comprising a tab extending from the free end portion, the tab configured to engage the planar platform when the clamp is in the closed position.

26. The pipe support of claim 1, wherein the base has a generally U-shaped cross section.

14. A pipe support system, comprising:

a pipe;

a pipe fitting coupled to the pipe to form a joint; and

a pipe support configured to restrain the pipe in close proximity to the fitting, the pipe support comprising;

a base configured to be secured to a support surface and having a planar platform configured to engage an outer surface of the pipe, the base further comprising at least one flange extending downward from a side edge of the planar platform and extending along a length of the platform, the at least one flange being generally perpendicular to the platform and configured to engage the support surface,

a clamp operable with the base to restrain the pipe, and

a hinge coupling the base and the clamp, and operable to facilitate movement of the clamp relative to the base between open and closed positions,

wherein the at least one flange positions the platform at a pre-determined distance from the support surface sufficient to offset a distance between the outer surface of the pipe and an outer surface of the pipe fitting, thereby preventing a bending load from occurring at the joint upon securing the pipe support to the support surface.

15. The system of claim 14, wherein the flange comprises at least two flanges extending downward from the platform, the at least two flanges being arranged in parallel to support the platform.

16. The system of claim 14, wherein the hinge comprises a compliant ligament extending between the base and the clamp, and wherein deflection within the pipe support is substantially confined to the compliant ligament.

17. The system of claim 16, wherein the compliant ligament is configured to limit stress therein sufficient to allow the hinge to undergo at least 10 close and open cycles comprising relative rotation between the clamp and the base sufficient to alternately secure and release the pipe.

18. The system of claim 14, wherein the hinge comprises a plurality of compliant ligaments.

19. The system of claim 14, wherein the hinge comprises a separable two-piece hinge, and wherein the clamp is attachable to the base upon assembly of the hinge.

20. The system of claim 14, further comprising a fastener coupling a free end portion of the clamp to a free end portion of the base to secure the pipe to the pipe support.

21. The system of claim 20, wherein the free end portion of the clamp is secured to the base using a single fastener.

22. The system of claim 20, wherein the free end portion of the clamp comprises a tab configured to engage the planar platform of the base when the clamp is in the closed position to secure the pipe support to the support surface.

27. The pipe support system of claim 14, wherein the base of the pipe support has a generally U-shaped cross section.

23. A method of restraining a pipe at a position in close proximity to a joint formed by the pipe and a pipe fitting, the method comprising:
