Expandable hanger for beam
An adjustable hangar for attaching an elongate beam to a structural building member includes a lower module and an upper module that are engaged with one another in a vertically reciprocal manner. The lower module includes a pair of parallel side panels spaced apart from one another and a lower beam support web. The upper module includes a top panel opposite the support web and a pair of opposite side members. The upper module further includes an upper support flange substantially parallel to the support web. In one embodiment, the upper module side members engage with the lower module in a vertically slidable relationship and define a beam receipt channel therebetween. When a beam is installed in the receipt channel, the upper and lower modules are adjusted vertically to trap the beam between the upper panel and support web with the beam circumscribed by the hanger.
1. A modular hanger for use in attaching an elongate beam to a building support structure, comprising:
an upper module with a top panel and opposite upper side units; and
a lower module engaged with the upper module, the lower module having a lower web for supporting an edge of the support beam and two opposite lower side units extending upwardly from the web, wherein
each of the upper side units is associated with one of the lower side units such that the top panel, upper side units, bottom panel and lower side units define an opening for receipt of the support beam, and
the upper and lower modules are vertically movable relative to each other to accommodate elongate beams having different height dimensions and trap a respective beam between the top panel and lower web.
2. The modular hanger of claim 1 , wherein the hanger is configured for the upper side units, lower side units, top panel and lower web to circumscribe a beam on its opposite sides, upper edge and lower edge.
3. The modular hanger of claim 1 , wherein the upper module and lower module are optionally vertically lockable relative to one another.
4. The modular hanger of claim 1 , wherein the top panel defines a viewing window from a top surface to a bottom surface.
5. The modular hanger of claim 1 , wherein each lower side unit comprises at least one toenail guide, each toenail guide defining an obliquely extending hole through the respective side unit.
6. The modular hanger of claim 5 , wherein each toenail guide comprises a boss cover configured to at least partially break away from the respective side unit when a fastener is driven through the hole.
7. The modular hanger of claim 1 , wherein the top panel defines an upper surface and opposite lower surface, and the upper surface is angled downward relative to the lower surface from a rear to a front.
8. The modular hanger of claim 1 , wherein the upper module and lower module are engaged in a vertically slidable relationship.
9. The modular hanger of claim 1 , wherein each of the lower side units defines a vertical track and each of the upper side units defines a guide that is receivable and vertically movable within a vertical track.
10. The modular hanger of claim 1 , wherein the web extends frontward and the upper module comprises a rearwardly extending flange defining a top surface and bottom surface, the bottom surface being substantially parallel to a top surface of the web.
11. A modular hanger for use in attaching an elongate beam to a building support structure, comprising:
an upper module with a top panel; and
a lower module engaged with the upper module, the lower module having a lower web for supporting an edge of the support beam and two opposite lower side units extending upwardly from the web, wherein
the upper module includes a pair of laterally spaced apart side legs, each side leg engaged with one of the lower side units to secure the upper module to the lower module, and
when engaged, the upper and lower modules are vertically movable relative to each other to accommodate support beams having different height dimensions or to adjust a height of the support beam relative to the building support structure with the support beam trapped between the top panel and the lower web.
12. The modular hanger of claim 11 , comprising a support flange extending rearwardly from the top module at a height proximate a height of the top panel, wherein the flange is configured to rest atop the support member and thereby ensure that the web and beam extend from the building support structure at a substantially perpendicular angle when attached.
13. The modular hanger of claim 11 , wherein each lower side unit comprises at least one toenail guide, each toenail guide defining an obliquely extending hole through the respective side unit.
14. The modular hanger of claim 11 , wherein each toenail guide comprises a boss cover configured to at least partially break away from the respective side unit when a fastener is driven through the hole.
15. The modular hanger of claim 11 , wherein the hanger is formed from a polymer or composite material.
16. The modular hanger of claim 11 , wherein the upper module comprises an upper right sub-assembly and an upper left sub-assembly.
17. The modular hanger of claim 16 , wherein the lower module comprises a lower right sub-assembly and a lower left sub-assembly, and wherein the upper and lower right sub-assemblies are laterally movable relative to the upper and lower left sub-assemblies to accommodate one or more joists having varying thickness dimensions.
18. The modular hanger of claim 17 , comprising an elastic band circumscribing the outside of the sub-assemblies and providing an inward bias holding the sub-assemblies toward one another.
19. A building assembly comprising:
a building support member having a front surface;
a hanger comprising an upper module with a top panel and a lower module with a bottom web, wherein the upper module and lower module are configured to be vertically movable between a fully collapsed configuration and a fully expanded configuration to trap an elongate beam between the top panel and bottom web;
an elongate beam trapped between the top panel and bottom web and extending forward from the hanger, wherein
the elongate beam and hanger are secured to the building support member front surface via a plurality of fasteners driven through the hanger and a rear portion of the beam and into the support member at oblique angles relative to the direction from which the beam extends from the front support surface.
20. The building assembly of claim 19 , wherein the building support member comprises a top surface and the upper module comprises a rear flange resting on the top surface with at least a portion of the top panel and the bottom web positioned in front of the building support member.
21. The building assembly of claim 20 , wherein the lower module comprises one or more lower panels with a vertical slot and the upper module comprises one or more upper legs with a guide received within the vertical slot of a respective lower side panel.
22. The building assembly of claim 20 , further comprising at least one set screw driven through an opening in one or both of the upper module and lower module and into the beam to set a position of the upper module, lower module and beam relative to one another.
23. The building assembly of claim 20 , wherein the upper module and lower module are lockable relative to each other in the fully collapsed position, fully expanded position, and one or more intermediate positions between the fully collapsed position and fully expanded position.
