Truss Anchor

US Patent:
5732524, Mar 31, 1998
Filed:
Apr 26, 1996
Appl. No.:
8/635414
Inventors:
William J. Kalker - Monroe CT
William C. Masters - Lakeland FL
Assignee:
Building Technologies, Inc. - Bartow FL
International Classification:
E04B 138
US Classification:
52712
Abstract:
The present invention is a truss anchor for attaching a truss to a wall system of a building frame. The truss anchor is a single piece of metal having a lower plate member and an upper plate member. The lower plate member has a first plate section defining an area of attachment to a vertically disposed surface of the truss. A lower extension is integral this first plate section and extends lateral the truss. An upper extension is integral the lower extension and extends upward therefrom adjacent the truss. The upper plate member forms a strap and includes a first strap section integral the upper extension and substantially perpendicular the lower plate member. A second strap section, integral the first strap section, extends laterally over the lower plate member and a third strap section, integral the second strap section, extends downward parallel the first plate section of the lower plate member. The invention also includes means for securing the lower plate member to the wall system and the upper plate member to the truss.

Tie Connector For Modular Buildings

US Patent:
5970677, Oct 26, 1999
Filed:
Nov 21, 1997
Appl. No.:
8/976415
Inventors:
William C. Masters - Lakeland FL
William J. Kalker - Monroe CT
International Classification:
E04B 138
US Classification:
52712
Abstract:
A tie connector for joining a modular type building or the like to the ground. One version of the tie connector having a flat substantially rectangular with an elongated slot through one side and at least one opening at the other end. The elongated slot provides an attachment site for a hurricane type strap to be inserted and coupled to a buckle. The opposite end of the tie connectors are attached to horizontal support members typically around the perimeter of the modular building. Another version of the tie connector having two flaps that wrap around two sides of a vertical support member allowing a bolt to be inserted through and be affixed. A final version of the tie connector having a vertical flap bent in a relatively perpendicular fashion such that the flap can be mounted around a side of a vertical support member. The hurricane straps are then inserted through the elongated slots and secured to a ground anchor. The elongated slot has the unique feature of rounded edges of sufficient radius thereby omitting any type of cutting effect that might occur when the straps are under high stress conditions.

Tie Connector For Modular Buildings

US Patent:
5701715, Dec 30, 1997
Filed:
Nov 21, 1995
Appl. No.:
8/561093
Inventors:

William J. Kalker - Monroe CT
Assignee:
Building Technologies, Inc. - Bartow FL
International Classification:
E04B 138
US Classification:
52698
Abstract:
A tie connector for joining a modular type building or the like to the ground. One version of the tie connector having a substantially L-shaped body with an elongated slot through one side. The elongated slot provides an attachment site for a hurricane type strap to be inserted and coupled to a buckle. The opposite end of the tie connectors are attached to horizontal support members around the perimeter of the modular building. The hurricane straps are then inserted through the elongated slots and secured to a ground anchor. Another version of the tie connector provides a Substantially L-shaped body with an additional vertical flap that can be affixed to vertical support members giving additional stability. The elongated slot has the unique feature of rounded edges of sufficient radius thereby omitting any type of cutting effect that might occur when the straps are under high stress conditions.

Outrigger Connector For A Factory Made Building

US Patent:
6247276, Jun 19, 2001
Filed:
Sep 7, 1999
Appl. No.:
9/391176
Inventors:
William C. Masters - Lakeland FL

Assignee:
Building Technologies, Inc. - Bartow FL
International Classification:
B60R 2700
US Classification:
5216912
Abstract:
A factory made building such as a mobile home (10) utilizing a connector (32, 60) attached to each of a plurality of outrigger beams (18) for stabilizing the mobile home (10) against strong winds. The mobile home (10) includes a structural support beam such as an I-beam (16) and a plurality of outrigger beams (18). An outrigger connector (32, 60) with an L-shaped portion (34) including a slot (46) and a protruding portion (56) extending outward from the L-shaped portion (34) at a substantially perpendicular angle is attached to each outrigger beam (18) at the protruding portion (56). A hurricane strap (48) is attached to the slot (46) and to a ground anchor (88) to secure the mobile home (10).
