Description
AN ENCLOSURE STRUCTURE
Field of Invention This invention relates to an enclosure structure. In particular, this invention relates to illl~luvelllents in an enclosure structure which can be erected S about a relatively large object for main~aillillg stable ellvilolllllental conditions thereabout.
Background of Invention During the construction or repair of large naval vessels, aircraft or other buildings and structures, it is desirable to build or erect a temporary 10 structure to enclose the space under repair or construction. Envi~olllllental conditions can be maintained within the structure in order to carry out certain repairs or construction steps.
In the case of large naval vessels, bllilrlings or structures, it is usually not possible to bring the vessel, building or other structure indoors. In the case 15 of aircraft, while it is possible to bring the aircraft into a hangar, it is not economically feasible to ~llvilonlllentally control the entire hangar in order to carry out certain repairs.
In the past, framed structures using traditional scaffolding have been erected about the vessel or aircraft. A plastic sheeting is attached to the 20 scaffolding to enclose the structure providing a controllable ellvilolllllent therein which can be stabilized using col~ven~ional heating, air conditioning and ventilating systems.
.
plovelllents have been made to the type of plastic sheeting which is used to enclose the framed scaffold structure. The sheeting has been reinrorced with various high strength fibers. High strength grommets are used to reinforce the plastic sheeting for attachment to the framed scaffold structure. Flexible S plastic ties have been threaded through the grommets and tied to the tubularscaffold frame. Other two piece connectors have also been used to connect the sheeting to the scaffold frame.
The convelllional connectors can only retain the plastic sheet next to the tubular scaffold frame. These connectors are unable to provide any stability along the length of the tubular frame member as the tie is allowed to slide along the length thereof.
Another problem which has been encountered using scaffolding, is that the scaffolding requires a relatively large area for its footing or foundation.
If the enclosure is required to be erected to cover the entire width of the deck of a large naval vessel, the footing or foundation with ~rcvent full access. The scaffold frame must be constructed from the ~u~lounding ground upwardly and then over the deck of the vessel. This additional structure increases the costs for undertaking such a project.
SummaIg of the Invention The disadvantages of the prior art may be uvercollle by providing an enclosure structure COlllpli.7illg a framed structure having a plurality of T-bolt fasteners for releasably connecting an outer sheeting to a framed structure.
It is desirable to provide a framed structure having a plurality of extruded tubular components having an outwardly facing T-bolt channel for receiving a T-bolt which is inserted through a grommet of an outer sheeting and secured within the T-bolt channel.
S It is desirable to provide a framed structure COlllpliSillg a pair of tubular members connected together with a plurality of stringers in a lateral like fashion.
According to one aspect of the invention, there is provided an enclosure structure colllplisillg a framed assembly defining a space to be enclosed and an outer sheeting for covering said framed assembly. The illl~ruvelllent complises a plurality of T-bolt fasteners releasably joining the outer sheeting to the framed assembly.
According to another aspect of the invention, there is provided an enclosure structure having a framed assembly and an outer sheeting covering the framed structure. The framed assembly defines a space to be enclosed. The framed assembly has a plurality of outwardly extending T-bolt channels. The outer sheeting has a plurality of holes therein. A plurality of T-bolt fasteners, each of which extends through one of said plurality of holes and engages the T-bolt channel releasably joining the outer sheeting to the framed assembly.

The T-bolt fastener 84 COlll~liSCS a bolt having a head 88 having awidth sub~lalllially equal to the opening 90 of T-bolt channel 82. Head 88 has alength a~ tely the inner width of T-bolt channel 82. In this manner, the head 88 may be inserted in the channel anywhere along the length thereof and thebolt 92 is engaged with the thread of the T-bolt to releasably secure the T-boltfastener thereto.
Preferably, the frame assemblies 12 and purlins 16 are extruded aluminulll. Alulllh~ulll is prefelable due to its relative light weight and strength.
Referring to Figure 18, the outer sheeting 14 is illustrated. The outer sheeting 14 is a sheet 94 ~rert;l~bly of low density polyethylene having reinrorced scrim 96 molded therein. Spaced about the sheet are grommets 98 for reinrorcing holes 100. Such sheeting is available under the trade-mark MONARFLEX T from Monarflex, Inc.
At the lower end of each extrusion of vertical members 18 have feet 102 for levelling the structure. As is a~parel-t, the area covered by the feet of the structure 10 is ",i~i",i~e-l Access is allowed between adjacent frame assemblies 12. As is apparent, the required floor space for erecting an enclosure structure 10 is l~
In use, the frame assemblies 12 are assembled using well known 5 con~l, uction techniques. The frame assemblies are then covered with strips of the sheeting 94. The head of T-bolt fasteners 84 are inserted through aperture 100 of grommet 98 and presented to a T-bolt channel of frame assembly 12. The bolt is rotated 90 for retention with the T-bolt channel and a nut 92 thre~(lingly engages the T-bolt firmly fastening the sheeting 94 onto the framed assembly.
10 The process is repeated until the sheeting fully encloses the enclosure structure 10. Adjacent rows of sheeting are then sealed together with adhesives or other known processes.
The above description relates to the ~lerelled apparatus by way of example only. Many variations on the invention will be obvious to those 15 knowledgeable in the field, and such obvious variations are within the scope of the invention, whether or not expressly described.
