Definitions

  • This invention relates to tanks and structure for supporting roots on the same. More particularly, this invention is concerned with an adjustable roof-supporting column that has particular use in tanks having roots supported by columns positioned on soil or other supporting sub-structure which "is subject to difierential subsidence or elevation.
  • Tanks with internal column-supported roofs are widely employed throughout the world to store various fluid materials, and particularly, oil, gasoline and other liquid petroleum materials. This type of construction can be used to make comparatively large tanks at a considerably lower cost than similar size tanks having truss roofs free of internal column supports.
  • Dilterential subsidence or elevation of the support on which a roofed tank having internal columns rests can occur at any time subsequent to erection, although substantial change can occur when a tank is subjected to a water-test for strength and leakage. Some such watertests last four weeks or more and during this time, it is not unusual for up to 75% of the settlement to take place. At times, settlement during a water-test may approximate 12 inches or more, with the settlement, of course, not being uniform from column to column or between columns and the peripheral 'soil area supporting the tank wall. It has accordingly been necessary to interrupt the Water-test to adjust the columns. Adjustment of the columns has been conventionally done by emptying the tank to obtain entry to the tank and apply suitable shims to the bottom of the column. This approach is inherently disadvantageous and time-consuming and accordingly, there has been a need for a system which would permit much more ready adjustment between the supporting columns and the roof to much better accommodate difterential settlement.
  • the “combination broadly comprises a column, a load “structure movable vertically supported or borne by 'the column, a supporting member connected'to the load structure and the column to support the load structure, and 5 means for displacing the supporting member while connected to the load structure to raise or lower the load structure.
  • the most suitable means 'for displacing the adjustable supporting member is screw means so that upon displacement of the screw, the supporting member will be raised or lowered and simultaneously secured in place against further displacement.
  • a tank for the storage of materials having a bottom, a side wall, 5 a roof and a plurality of vertically disposed columns within said tank supporting said roof, which comprises adjust able means connecting the upper ends of said columns with said roof whereby vertical displacement of said columns, and commensurate displacement of the columnsupported roof, resulting from soil or foundation subsidence or elevation beneath the columns can be compensated for by adjustments made in said adjustable means to raise or lower the roof, said adjustable means being operably adjustable from outside the tank.
  • FIGURE 1 is a plan view, partially broken away, of a tank with adjustable columns supporting the roof;
  • FIGURE 2 is a side elevation, partially in section and broken away, of the tank of FIGURE 1', and
  • FIGURE 3 is a vertical sectional "view taken along the line 3--3 of FIGURE 1.
  • FIGS. 1 and 2 show cone roofed tank 10 having wall 11, cone roof 12 and bottom plate 13.'Roof 12 is supported about its periphery on the upper edge of wall 11. In addition, the roof is supported by central column 14 4.0 and a course of six essentially identical columns 15 positioned in a ring. Girders 16 run from two-adjacent columns 15 and are initially supported at their ends by flange 17. The girders 16 can be I-beams or other suitable structural members. A series of rafters 18 are positioned to rest at their outer ends on a ring 40 positioned around the upper inside edge of the tank wall 11, and wit]: the inner end of the rafter resting on a girder 16.
  • rafters 18 are positioned betweer each two adjacent columns 15, spaced apart at about 15 radial angles.
  • Rafters 19 are positioned to run from th central column 14 to rest on girders 16 at their outer ends
  • Two such rafters '19 can be positioned to rest on 'eaci girder-163.1; approximately a 30 radial angle betwee two adjacent columns 15.
  • the described arrangement t supporting columns, girders and rafters is a convention: arrangement in a cone roof tank, and its description he: is primarily to facilitate the description and utilizatic of the subject invention.
  • tubular column exte 'sion 20 advisably welded at its lower edge to plate 1
  • plate Q mounted on the upper end of tubular extension 20 which, together with plate 23 and pin 24, for; a pivot connection.
  • bracket 22 Connected to plate 2 3, such as welding, is extension bolt 25, which projects upwan through hole 26 above the top of plate 21. Washer 21 placed over the end of bolt 25 and nut 28 secur threaded thereon.
  • Attached to the end of each girder is a horizontal semicircular 'guitle'mean's 30 formed visably out of round stock.
  • the guide means 30 can conveniently attached to the end of the girder b to permit vertical movement of the g1rder end while prethe upper portion of the column while the tank is full.
  • vertical ring 31 Positioned around the perip ery of hole 32 is vertical ring 31 which keeps water from flowing into the hole.
  • Hole 32 is covered by cap 33 which has cylindrical wall 34 and top 35.
  • inverted angle 36 Positioned along the lower outside edge of wall 34 is inverted angle 36 which circumscribes cap 33 so that when the inner edge 37 of the cap is positioned inside of ring 31, the angle 37 will fit over and around the outer edge of ring 31 to form a weather seal.
  • Handles 38 are provided on wall 34 for manual removal and repositioning of the weather-protecting cap 33.
  • Central supporting column 14 can also be provided with column-adjusting means as already described in conjunction with columns 15.
  • Each of the rafters 19 can be suspended by means of the bolt means 25 adjacent their ends abutting the central column.
  • all columns positioned internally of the tank can be constructed to provide for adjustment for differential movement of each column independent of the others.
  • the improved tank of claim 1 having means for ac cess to said adjustable me and supporting said roof,
  • adjustable means connecting the upper ends of said columns with said to raise or lower the roof
  • a tank comprising a bottom, wall and roof
  • said roof being supported by the wall and a plurality of vertical columns in the tank, at least some of said columns being adjustable columns,
  • the adjustable columns each having adjustable support means near the upper end thereof, and connected to the roof, for supporting the roof,
  • each adjustable column has flange means for supporting a roof girder end, the lower end of the suspending member is joined to the girder end, and the girder end has means to prevent horizontal displacement of the girder out of register with the column.
  • a tank according to claim 8 in which tension is applied to the suspending member by screw means to raise the roof girder and roof thereon.
  • a tank according to claim 7 having a weather cap over the top of the column and depending to the roof surface.
  • a column and adjusting means for adjusting the height of a structure borne by the column comprising a column, a load structure movable vertically borne by the column, a supporting member connected to the load structure and the column to support the load structure,
  • a supporting member having a lower end joined to the load structure and an upper end secured to the column to support the load structure by tension in the supporting member
  • a screw means on the upper part of the supporting member to achieve displacement of the supporting member.
