Abstract

An improved jacketing system for storage tank structures wherein insulated panels are attached to modular tracks mounted in horizontal courses on the outside walls of the tanks. The individual tracks are made up of modular segments secured together both by splice plates and take-up devices in an improved pretensioned fashion to provide for an efficient mounting of the panels on a tank wall.

Claims

1. An insulated jacketing system for an upstanding cylindrical tank wall and the like comprising at least one pretensioned circular track means made up of a plurality of individual track segments each having multi-perforated ends disposed immediately adjacent the tank wall and each of which is provided with an outwardly facing recess, means for splicing certain opposing and adjacent multi-perforated ends of selected track segments together, said means comprising a splice plate provided at each of its ends with a plurality of struck out lug portions engageable with a corresponding plurality of similarly shaped and matching perforations on the said ends of the selected track segments, track take-up means including rod elements and plates having multi-struck out lug elements engaging and holding other opposing and adjacent multi-perforated ends of selected track segments together, the splice plate and the take-up plate each are channel shaped in cross section, insulated panels secured crosswise to said track segments, said panels comprising channel-shaped sections having opposing upstanding flanges one of which comprises a terminal bead and the other of which comprises a deformable sleeve that can be folded tightly about the bead on a similarly configured channel-shaped section disposed adjacent thereto, insulating material affixed to the underside of each panel and clip means provided with a head portion insertable within and engageable with the bead of one panel and a foot element insertable within the outwardly facing recess of a track segment.

2. A system as set forth in claim 1 wherein a track segment comprises a channel-shaped section provided with inturned flanges for directly contacting and supporting the insulated panels.

3. A system as set forth in claim 1, wherein the struck out lug portions of the splice plate are reversely oriented on opposite ends of the plate.

4. A system as set forth in claim 3 wherein the track take-up means includes a channel-shaped plate for receiving selected parts of the rod elements.

5. A system as set forth in claim 1 wherein the rod elements are torque rod elements.

6. An insulated jacketing system for an upstanding cylindrical tank wall comprising a plurality of pretensioned circular trackways horizontally arranged in a generally parallel and spaced relation to each other along and in contact with the wall, each trackway being made up of a plurality of individual track segments and each track segment being generally channel-shaped in cross-section so as to be provided with an outwardly facing recess, splice plate means for splicing the opposing and adjacent ends of selected track segments together, said splice plate means having a plurality of struck out lug portions at each end of the splice plate means insertable within a corresponding plurality of similarly shaped and matching apertures on the said ends of the track segments, a track take-up means comprised of a pair of plates each of which is provided with multiple lugs insertable within similarly shaped and matching apertures on the end of a selected track segment and torque rod elements engageable with each plate, the splice plate and the take-up plate each are channel shaped in cross section, insulated panels secured crosswise of and upon said track segments, said panels comprising channel-shaped metal sections having opposing upstanding flanges one of which comprises a terminal bead and the other of which comprises a deformable sleeve that can be folded tightly about the bead on a similarly configured channel section disposed adjacent thereto, insulating material affixed to the underside of each panel and clip means portions of which are engageable with the bead of one panel and a track segment for securing the panels crosswise to the track segments.

7. A system as set forth in claim 6 wherein the channel-shaped track segments are provided with flanged lips that act as bearing surfaces for the insulated panels.

8. A system as set forth in claim 6, wherein the struck out lug portions of the splice plate means are reversely oriented on opposite ends of the plate means.
