Abstract

A sliding hold-down clip (1) for connecting a roof panel (52) to a purlin (52) in which a support portion (14) extends from a base (12), the support portion defining a slot (20) with fasteners (34) that connect to a roof-engaging plate (36), the fasteners guiding longitudinal movement of the roof-engaging plate (36) along the slot relative to the clip, a distal end of the plate defining a hook (40) for connecting to edges of adjacent roof panels (52), a pair of opposing wings (46, 48) extending laterally from the roof-engaging plate (36) and angled to conform to an anglation of a side portion of the roof panel, whereby fasteners (58) extending though the roof panel and the wings secure the roof panel to the roof-engaging plate. A method of securing roof panels to purlins is disclosed.

Claims

1. A sliding hold-down clip for connecting a roof panel to a purlin in which the clip has a base that defines openings for receiving fasteners to secure the clip to the purlin, the clip defining a slot in a support portion extending from the base, a roof-engaging plate connected by fasteners through the slot for guiding longitudinal movement of the roof-engaging plate along the slot relative to the clip, a distal end of the plate defining a hook for connecting to edges of adjacent roof panels, the improvement comprising a pan received on the roof-engaging plate between the hook and an upper edge of the support portion, the pan having a central portion and two opposing wing portions extending lateral of the central portion, the wing portions for bearing against respective roofing panels and receiving a fastener through the roof panels and the wing portion to secure the wing portion to the roof panels.

2. The improved clip as recited in claim 1, wherein the wing portions extend at an angle relative to the central portion, the angle conforming to an angle defined by the edge portion of the roof panel.

3. The improved clip as recited in claim 1, wherein herein the clip includes a detachable locking pin to secure the roof-engaging plate in a central intermediate portion of the slot, the detachable locking pin released after connection of the hook to a first one of the roofing panels, and wherein the pan further defines at least one hole in a lateral portion for passage of a tool to release the locking pin.

12. The improved clip as recited in claim 1, wherein the pan further comprises an area defining an aperture therethrough sized and shaped to receive at least a portion of the roof engaging plate.

4. A clip for connecting a roof panel to a purlin, comprising:

an angle member defining a base and a support portion extending at an angle from the base,

the base adapted for engaging to a purlin;

the support portion defining a slot therein;

a roof-engaging plate connected by fasteners extending through the slot, the fasteners guiding longitudinal movement of the roof-engaging plate along the slot relative to the support portion; and

a pan engaged to the roof-engaging plate, the pan having a central portion and two opposing wing portions extending laterally of the central portion, the wing portions for bearing against respective roofing panels and receiving a fastener through the roofing panel and the wing portion to secure the wing portion to the roofing panel.

5. The clip as recited in claim 4, wherein the roof-engaging plate defines an extending distal end for connecting to an edge portion of a roofing panel.

6. The improved clip as recited in claim 4, wherein the wing portions extend at an angle relative to the central portion, the angle conforming to an angle defined by a side portion of the roof panel.

13. The improved clip as recited in claim 4, wherein the pan further comprises an area defining an aperture therethrough sized and shaped to receive at least a portion of the roof engaging plate.

7. A sliding hold-down clip connected to a roof panel in which the clip has a base that defines openings for receiving fasteners to secure the clip to a purlin, the clip defining a slot in a support portion extending from the base, a roof-engaging plate connected by fasteners through the slot for guiding longitudinal movement of the roof-engaging plate along the slot relative to the clip, a distal end of the plate defining a hook for connecting to edges of adjacent roof panels, a pair of opposing wings extending laterally from the roof-engaging plate and angled to conform to an anglation of a side portion of the roof panel, whereby fasteners extending through the roof panel and the wings secures the roof panel to the roof-engaging plate.

8. The sliding hold-down clip as recited in claim 7, wherein the wings extend from a central portion of a pan received on the roof-engaging plate between the hook and an upper edge of the support portion.

9. A method for connecting roof panels to purlins with a sliding hold-down clip, comprising the steps of:

(a) securing sliding hold-down clips in a spaced-apart relation to a purlin, each of the sliding hold-down clips having a base that defines openings for receiving fasteners to secure the clip to the purlin, the clip defining a slot in a support portion extending from the base, a roof-engaging plate connected by fasteners through the slot for guiding longitudinal movement of the roof-engaging plate along the slot relative to the clip, a distal end of the plate defining a hook for connecting to edges of adjacent roof panels, and a pair of opposing wings extending laterally from the roof-engaging plate and angled to conform to an anglation of a side portion of the roof panel;

(b) installing at least one roof panel on the purlin to partially cover a space; and

(c) placing fasteners through the roof panel and one of the wings covered by a portion of the roof panel,

whereby the fasteners extending through the roof panel and the wing secures the roof panel to the roof-engaging plate.

10. A clip for connecting a roof panel to a purlin, comprising:

an angle member defining a base and a support portion extending at an angle from the base,

the base adapted for engaging to a purlin;

the support portion defining a slot therein;

a roof-engaging plate slidingly engaged with the slot for guiding longitudinal movement of the roof-engaging plate along the slot relative to the support portion; and

a pan engaged to the roof-engaging plate, the pan having a central portion and two opposing wing portions extending laterally of the central portion, the wing portions for bearing against respective roofing panels and receiving a fastener through the roofing panel and the wing portion to secure the wing portion to the roofing panel.

14. The improved clip as recited in claim 10, wherein the pan further comprises an area defining an aperture therethrough sized and shaped to receive at least a portion of the roof engaging plate.

11. A method for connecting roof panels to purlins with a sliding hold-down clip, comprising the steps of:

(a) securing sliding hold-down clips in a spaced-apart relation to a purlin, each of the sliding hold-down clips having a base that defines openings for receiving fasteners to secure the clip to the purlin, the clip defining a slot in a support portion extending from the base, a roof-engaging plate slidingly engaged with the slot for guiding longitudinal movement of the roof-engaging plate along the slot relative to the clip, a distal end of the plate defining a hook for connecting to edges of adjacent roof panels, and a pair of opposing wings extending laterally from the roof-engaging plate and angled to conform to an anglation of a side portion of the roof panel;

(b) installing at least one roof panel on the purlin to partially cover a space; and

(c) placing fasteners through the roof panel and one of the wings covered by a portion of the roof panel, whereby the fasteners extending through the roof panel and the wing secures the roof panel to the roof-engaging plate.
