Pultruded panel
First Claim
1. A floor assembly mounted on a railway car underframe comprising:
- a plurality of panels with each panel having a first longitudinal edge profile and a second longitudinal edge profile;
the panels disposed adjacent to each other with the first longitudinal edge profile coupled with the second longitudinal edge profile of adjacent panels;
a respective projection formed on one of the longitudinal edge profiles to create a gap between the respective longitudinal edge profiles of the adjacent panels;
an adhesive disposed within each gap to bond the first longitudinal edge profile with the second longitudinal edge profile of the adjacent panels;
the panels disposed on and secured to the railway car underframe;
a first end located proximate a first end of the railway car underframe;
a second end located proximate a second end of the railway car underframe;
a central portion of the floor assembly disposed between the first end and the second end of the railway car underframe;
the central portion of the floor assembly adhesively bonded with adjacent portions of the railway car underframe;
at least one restraining anchor coupled with the floor assembly and the railway car underframe proximate the first end thereof;
at least a second restraining anchor coupled with the floor assembly and the railway car underframe proximate the second end thereof;
wherein each restraining anchor further comprises;
a first member securely coupled with one of the panels;
a second member securely coupled with adjacent portions of the railway car underframe;
at least one of the first and second members having a slot formed therein; and
a bolt extending through the first member, the slot and the second member to allow limited longitudinal movement of the first member relative to the second member to limit any vertical movement during thermal expansion and contraction of the floor assembly relative to the railway car underframe.

Abstract
Pultruded panels having a first longitudinal edge profile and a second longitudinal edge profile may be used to form a floor assembly mounted on a railway car underframe. The pultruded panels may also be used to form walkways, bridges, piers and other structures. A bead may be placed on at least one of the longitudinal edge profiles to form a gap between an adjacent pultruded panel. An adhesive may be placed within the gap to couple or bond adjacent pultruded panels with each other. Void spaces may be formed within the pultruded panel and filled with foam to provide improved resistance to heat transfer through the respective panel. Respective coverings may be placed on opposite ends of each panel to block access to the associated void spaces.

2. A pultruded panel comprising:
-
a generally rectangular configuration defined in part by a first end and a second end with a first longitudinal edge profile and a second longitudinal edge profile spaced from each other and extending between the first end and the second end;
a plurality of void spaces formed within the pultruded panel;
each void space filled with an insulating foam;
the first longitudinal edge profile defined in part by a first lip extending laterally therefrom and a first recess formed in the pultruded panel;
the second longitudinal edge profile defined in part by a second lip extending literally therefrom and a second recess formed in the pultruded panel;
at least one projection formed on one of the longitudinal edge profiles to create a gap when a longitudinal edge profile of another pultruded panel is disposed adjacent thereto;
the projection sized to allow the gap to receive an adhesive to bond the pultruded panel with an adjacent pultruded panel;
the void spaces extending from respective openings in the first end to respective openings in the second end of the pultruded panel;
a respective covering placed over the openings at each end of the pultruded panel to block access to the void spaces; and
more than two projections formed on the longitudinal edge profiles.
