Abstract: A simple and inexpensive method and apparatus for molding a peripheral frame around a sheet or grid of thermoplastic material to produce a framed panel. A peripheral frame, preferably of structural foam or the like, is injection molded about a thermoplastic sheet or grid of panel-forming material which has been previously drawn or stretched at a temperature which orients the molecules of the polymer, i.e., below the glass transition temperature of the polymer, T.sub.g. Either during the frame molding process, or subsequent thereto, the panel-forming material is heated sufficiently to cause the material to shrink or revert toward its prestretched condition so as to tension the panel-forming material within the frame. Elastomeric sealing means are disclosed for sealing the mold during injection of the frame-forming material and locator fingers are provided to position a grid-like panel-forming material prior to initiation of the molding process.

The body (46) of the connector is received in a channel (86) of one structural member (80A). Jaws (34) formed on the top (18) of each bar (12A, 12B) may be received in a slot (92) of a second structural member (80B) and the jaws thereafter urged apart by a spreader member (70) to grippingly engage the slot (92) and lock the structural members (80A, 80B) together. Camming surfaces (42) of the jaw sections (34) facilitate use of connector (10) over a wide range of wall thicknesses at the slot (92).

Each housing comprises a grooved track for the slider, and each track is sagged down to its middle where the slider rests under normal conditions. When the blast occurs, the wall panel does not transfer its impulse to the building frame immidiately but, remaining parallel to its initial position, distributes this transferal during a sequence of pendulum type excursions thus considerably mitigating the explosion impact on vital structural elements of the building.

Abstract: A new attachment plate is provided for securing components of panel assemblies to a mounting post, the attachment plate incorporating a securing hook together with a locking tab. The attachment plate includes a projecting hook which mates with a slot in a mounting post structural member. The hook is of a lesser length than the slot in the post, and a further projection as a locking tab is provided on the attachment plate which also enters the slot and restrains reversed relative movement between the plate hook and the post slot, so as to limit or prevent undesired disassembly of a panel from the post. The application of an upward impact to the plate causes a cam surface on the locking tab to contact the upper end of the mounting post slot. This deflects the locking tab out from the slot, to enable removal of the hook from the slot, for panel disassembly from the post. Also provided is a hooked supporting plate incorporating pairs of flexible presser tabs, to compensate for manufacturing tolerances.

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.
