Abstract
Abstract A composite structure, comprising supporting members and connection bridges. Each supporting member comprises a beam, a girder or a panel, and is longitudinally recessed over at least part of at least one longitudinal face. The recessed supporting member has a web, which is preferably resilient and which in effect constitutes the bed of a longitudinally extended channel, having on each of its two sides a locking recess. Each locking recess is bounded by a flank, or bank of the channel, forming one of the sides of the supporting member. The combination also includes connection bridges, each constituting a modular unit. At least parts of these bridges are dimensionally adapted to the shape and dimensions of the supporting members. Each bridge is transversely elastically fitted into the recessed portion of such a member so as to become fixed thereto and to resist longitudinal wrenching and displacement therein or therefrom. The preferred structure also includes minisections interposed between the supporting members and the connection bridges.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
172 words
A composite structure, comprising: a. an elongate supporting member having a generally U-shaped cross-sectional configuration, the arms of which provide two longitudinal flanks of said member and said U-shaped configuration providing a web between said arms, at least part of at least one of said flanks having at least one longitudinal recess of a generally C-shaped cross-sectional configuration; and b. a plurality of bridge members disposed to stiffen the elongate supporting member, each bridge member comprising a rigid deck, at least two rigid piers, one at each end of said deck, and sharp-edged spur means on at least one of said piers engageable with the supporting member, said bridge members being spaced apart along the elongate supporting member, each bridge member having its deck extending between said flanks and spaced from said web; at least one of said members being resilient to enable the bridge members to be clamped transversely in the supporting member with said spur means engaging said flanks, to resist any wrenching and longitudinal displacement of the bridge members.
Claim 2
Dependent Claim
172 words
A composite structure, comprising: a. an elongate supporting member having a generally U-shaped cross-sectional configuration, the arms of which provide two longitudinal flanks of said member and said U-shaped configuration providing a web between said arms, at least part of at least one of said flanks having at least one longitudinal recess of a generally C-shaped cross-sectional configuration; and b. a plurality of bridge members disposed to stiffen the elongate supporting member, each bridge member comprising a rigid deck, at least two rigid piers, one at each end of said deck, and sharp-edged spur means on at least one of said piers engageable with the supporting member, said bridge members being spaced apart along the elongate supporting member, each bridge member having its deck extending between said flanks and spaced from said web; at least one of said members being resilient to enable the bridge members to be clamped transversely in the supporting member with said spur means engaging said flanks, to resist any wrenching and longitudinal displacement of the bridge members.
Claim 3
Dependent Claim
52 words
A structure according to claim 1 including at least one minisection which comprises an auxiliary elongate member separably engageable with the supporting member and the bridge members and extending along the supporting member to cooperate therewith and with the bridge members in the clamping of the bridge members in the supporting member.
Claim 4
Dependent Claim
39 words
A structure according to claim 2 wherein each minisection comprises first and second wings parallel to and approximately coextensive with the support member, and means interconnecting said wings to define a tubular section by said wings and supporting member.
Claim 5
Dependent Claim
37 words
A structure according to claim 2 including a second supporting member extending along the first-mentioned supporting member, and means for interconnecting the supporting members, comprising at least one of the minisections extending along the two supporting members.
Claim 6
Dependent Claim
24 words
A structure according to claim 2 wherein at least one of the minisections comprises means for rigidifying at least parts of the supporting member.
Claim 7
Dependent Claim
31 words
A structure according to claim 1 including a second support member extending along the first, and means including at least one of the bridge members for interconnecting the two support members.
Claim 8
Dependent Claim
53 words
A structure according to claim 1 in which at least two of said bridges have their decks joined back-to-back, each having a first half-deck integrally extending from at least one of its piers, a second half-deck similarly extending and facing the first half-deck and a cross-bracing flange between the half-decks and secured thereto.
Claim 9
Dependent Claim
40 words
A structure according to claim 7 in which the cross-bracing flange has a substantially U-shaped cross-sectional configuration and is disposed to enable the two bridges, joined by their decks, to be locked to similar co-planar bridges of another supporting member.
Claim 10
Dependent Claim
37 words
A structure according to claim 2 in which the auxiliary support member has a generally C-shaped cross-sectional configuration which fits into and engages the longitudinal recess of one of the longitudinal flanks of the elongate supporting member.
