Abstract
A structural member can be used alone or paired with a like member for use as an upright or cross member of a support structure. This structural member has particular application in greenhouse structures where a support structure is formed for retaining transparent panels. The structural members are preferably made of rolled steel and are of a generally `T` configuration with a pair of retaining flanges. The structure simplifies manufacturing by accommodating punching of various fastening ports or forming of securing flanges prior to the rolling operation. Any shaping of the members is easier as the shaping may be carried out on individual members prior to pairing of the members to form an upright or cross member.
Claims14
In combination, two corresponding structural members, each structural member comprising a generally `T` configuration at an upper side edge having a downwardly and inwardly directed retaining flange, the base of said `T` configuration having to the side of said base opposite said retaining flange an upwardly and inwardly extending retaining flange,
- said structural members being held in back to back relation with the top portion of said `T` configurations abutting to define a configuration generally symmetrical about the plane of said abutting top portions.
In a greenhouse assembly having a number of upright members and a number of cross members mechanically secured to define frame network which receives and supports greenhouse panels, said upright members and said cross members each being based on a structural member comprising a generally `T` configuration having, at an upper side edge, a downwardly and inwardly directed retaining flange, the base of said `T` configuration having to the side of said base opposite said retaining flange an upwardly and inwardly extending retaining flange.
In a garden shed an add-on greenhouse assembly having a number of upright members and a number of cross members mechanically secured to define a frame network which receives and supports greenhouse panels, said upright members and said cross members each being based on a structural member comprising a generally `T` configuration, said upright members and said cross members being mechanically secured by positive engagement, each of said structural members being formed of a rolled steel material, said cross members each being defined by a pair of cooperating structural members secured in back to back relation defining a generally "+" configuration, said cross members including notched end portions with a securing flange bent generally perpendicular to the longitudinal axis of said structural member which forms part of the mechaincal securement of the cross member to an upright member.
