US3826057A — Truss system

Claim 1

Independent Claim 288 words

A composite truss for use in connection with building construction operations comprising at least two truss components interconnected each to each in end-to-end relationship; each of said truss components having top and bottom chord elements, a plurality of struts for maintaining said chords in vertically spaced apart positions, said top and bottom chord elements providing a plurality of strut engagement receptacles in paired disposition at equally spaced panel points along said chords to facilitate the interengagement of said chords and the ends of each of said struts, said chord elements further having the panel points and the paired receptacles thereat that are adjacent the ends of each chord element disposed a distance away from the chord ends equal to one-half the regular panel point spacing interval, said struts further providing holes through the lateral sides thereof to facilitate the interengagement of said chords and struts when in the operative assembled relation, assembly pin elements interconnecting said chords and struts for the transmission of the forces to be carried by said truss component and for holding the chords and struts in an operative assembled relation wherein the panel point positions for top chords are vertically and longitudinally offset one-half of a regular panel point spacing interval with respect to the position of the panel points for the bottom chords; and additionally comprising at least two chord coupler elements interconnected to and joining the ends of the top and bottom chords for said separate truss components for the transmission of loadings therebetween, and an additional discrete strut element interconnected to each of the separable truss components and extending therebetween to complete a regular pattern and disposition of strut elements whereby the assembled composite truss has uniform strength and loading characteristics.

Claim 2

Dependent Claim 288 words

A composite truss for use in connection with building construction operations comprising at least two truss components interconnected each to each in end-to-end relationship; each of said truss components having top and bottom chord elements, a plurality of struts for maintaining said chords in vertically spaced apart positions, said top and bottom chord elements providing a plurality of strut engagement receptacles in paired disposition at equally spaced panel points along said chords to facilitate the interengagement of said chords and the ends of each of said struts, said chord elements further having the panel points and the paired receptacles thereat that are adjacent the ends of each chord element disposed a distance away from the chord ends equal to one-half the regular panel point spacing interval, said struts further providing holes through the lateral sides thereof to facilitate the interengagement of said chords and struts when in the operative assembled relation, assembly pin elements interconnecting said chords and struts for the transmission of the forces to be carried by said truss component and for holding the chords and struts in an operative assembled relation wherein the panel point positions for top chords are vertically and longitudinally offset one-half of a regular panel point spacing interval with respect to the position of the panel points for the bottom chords; and additionally comprising at least two chord coupler elements interconnected to and joining the ends of the top and bottom chords for said separate truss components for the transmission of loadings therebetween, and an additional discrete strut element interconnected to each of the separable truss components and extending therebetween to complete a regular pattern and disposition of strut elements whereby the assembled composite truss has uniform strength and loading characteristics.

Claim 3

Dependent Claim 40 words

The truss system as set forth in claim 1 wherein said chords are of holloW rectangular tubing and wherein said strut receptacles are inwardly disposed openings provided in said tubing and extending laterally to the sidewalls of the chord section.

Claim 4

Dependent Claim 29 words

The truss system as set forth in claim 2 wherein the struts are of rectangular tubing for close mating engagement in said openings in contact with said lateral sidewalls.

Claim 5

Dependent Claim 29 words

The truss system as set forth in claim 1 wherein the assembled truss is of added height and further comprising extensions for said struts to increase the length thereof.

Claim 6

Dependent Claim 54 words

The truss component as set forth in claim 1 wherein struts are installed to extend in ''''V'''' pattern between the strut receptacles of the bottom chord and the strut engagement receptacles of the top chord whereby at least one strut receptacle is unused at each of the opposite ends of each said truss component.

Claim 7

Dependent Claim 26 words

The truss component as set forth in claim 5 wherein the unused strut receptacles at opposite ends of the truss component are on the same chord.

Claim 8

Dependent Claim 25 words

The truss component as set forth in claim 5 wherein the unused strut receptacles at opposite ends of the truss component are on separate chords.

Claim 9

Dependent Claim 61 words

The truss system as set forth in claim 1 wherein the chord couplers at the ends of said chords provide holes therethrough with mating holes being provided in the lateral sides of said chords, and further comprising additional pin elements for engagement through the mating holes of couplers and chords for holding the chords of the plurality of truss components together.

Claim 10

Dependent Claim 106 words

The truss system as set forth in claim 8 wherein the chords and struts are of rectangular tubing and at least two of said truss components are of unequal height providing an offset configuration, and further comprising transition gusset plates for disposal on opposite lateral sides of one chord to be joined, an additional chord coupler applied in the end of a second chord to be joined, and a bushing component on the outwardly extending end of said additional coupler, said additional chord coupler, bushing and gusset plate components providing mating holes therethrough whereby the transition gusset plates are effectively joined to each of said chords.

Claim 11

Dependent Claim 52 words

The truss system as set forth in claim 8 wherein said struts are of hollow rectangular tubing and further providing a strut connector to fit telescopically within said strut, and a bushing element of outer size corresponding to the size of said strut for fitting engagement over the end of said coupler.

Claim 12

Dependent Claim 23 words

The truss system as set forth in claim 8 wherein said chords and chord coupler are of rectangular cross-section for mating telescoping engagement.

Claim 13

Dependent Claim 37 words

The truss system as set forth in claim 10 wherein said bushing and connector have lateral holes therethrough and further comprising lateral holes through said chords for mating alignment with the holes through said bushing and connector.

Claim 14

Dependent Claim 61 words

The truss system as set forth in claim 12 and further comprising an extended strut connector for use with said truss components, said extended strut connector providing a plurality of length adjusting bolt holes therethrough whereby the struts and extended connectors at successive positions along the length of the chord may be of increasing effective length to provide an inclined truss.
