bottom ends of the posts to threadedly connect with anchor members 33 that are mounted in transverse openings 34 extending transversely through the posts at points spaced from the lower 5 ends thereof. The anchor memb-ers are preferably formed of metal and of substantially cylindrical shape to closely iit within the openings 34, but are of shorter length than the thickness of the posts so that the ends 35 and 36 thereof are l spaced from the adjacent side faces 31 and 38 and provide recesses 39 and 49 into which insulating plugs 4| and 42 are driven to seal the anchoring members from contact with the contents of the tank, the plugs 4I and 42 being pref- 15 erably wedged within the recesses and further sealed by a suitable cement impervious to corrosive action of the fluid.

The anchoring members 33 are provided with threadedsockets 43, aligning with the bores 32, to engage the threaded ends 44 of the stud bolts 3&3. The lower ends 45 of the studs extend through aligning openings 4B and 41 in the respective footing members and in the underlying floor boards l2 respectively, the openings 4E being of sucient diameter to accommodate nuts 48 that are threaded on the stud bolts, but the openings 41 are of suitable size to snugly iit the stud bolts, thereby providing shoulders 49 for seating washers 55 that are clampingly retained against the floor boards by the nuts 46.

The stud bolts 30 are similarly mounted in axial bores i in the upper ends of the posts and have threaded ends 52 threadedly engaging in the sockets of similar anchor members 53 located in transverse openings 54 of the posts. The upper ends of the stud bolts project through aligning openings 55 and 55 in the stringers 28 and 29 and in the overlying boards of the roof deck respectively. The bolts are of suiiicient length to project a material distance from the boards, and are provided with threads to mount nuts 51 which retain washers 58 thereon in clamping engagement with the roof board and to effect drawing of the boards against the stringers 28 and 29, and the stringers' tightly against the upper ends of the posts. To further enhance the seal at the ends of the posts a suitable tank cement is applied thereon prior to drawing up of the stud bolts.

The structure thus far described provides supports to prevent inward buckling of the tank heads under external pressures, and in order to prevent outward buckling of the heads when the internal pressures exceed the external pressures, the lower stud bolts 3| project through openings 59 in clamping plates 6D that cooperate with footing plates to clamp the lower head therebetween when nuts 6| are threaded on the stud bolts, as shown in Fig. 3.

The nuts 5| include washer-like ange portions 52 having prongs or spurs 63 for projection into the body of the clamping plates to prevent rotation of the nuts when the stud bolts are drawn up in the assembly of the tank, as later described.

Cooperating with the stringers 28 and 29 are clamping stringers B4 and 65 that extend transversely across the outer surfaces of the roof boards, and which are provided with counterbored openings 66 extending therethrough to allow projection of the upper ends of the stud bolts and to accommodate the nuts 51.

In order to anchor the clamping stringers, the free endsy of the stud bolts are provided with washers 61 and clamping nuts 68, as best shown in Fig. 3. The stringers are of sucient length to extend substantially across the tank, and the outer or unsupported ends thereof are clamped together and to the roof boards by stud bolts 59 which extend through aligning openings 10, 'il and 12 in the ends of the stringers and roof board respectively, the ends of the stud bolts being threaded and provided with washers and nuts 13 and 14. The nuts 15 on the interior of the tank preferably are of non-corrosive material and are of cap form to protect the stud bolt from the corroding inuence of the liquid in the tank.`

With the construction thus described it is clearly obvious that the stud bolts are completely shielded from the corrosive action of the fluid since they are completely closed within the parts which they connect. They also permit of ready assembly of the tank, as now to be described.

in assembling the tank, the iioor boards having the openings 41 are turned'on edge and the nuts 48 are run onto the studs 3i a sufcient distance to accommodate the boards and clamping plates, and to allow suicient projection for accommodating the nuts 6l.

The stud bolts are then projected through the openings in the planks and openings 59 in the bottom clamping plates.l The nuts 6i are then applied to the projecting ends of the stud bolts, after which the nuts 48 are drawn tightly against the head to cause the prongs on the nuts 6l to be drawn into the clamping plates, thereby preventing rotation of the nuts 5I. r

The footing plates are then applied so that the openings 46 therein pass over the nuts 48 to lie crosswise of the flooring boards. rIhe openings 45 are then iilled over the nuts with tank cement. The anchoring members 33 are then inserted in the openings of the posts and the posts are slid longitudinally onto the stud bolts. The lower ends of the posts are then smeared With tank cement and the threaded ends of the stud bolts are caused to engage in the threaded sockets or the anchoring members. The posts are then rotated to tighten the ends thereof rigidly against the footing plates. The recesses 39 and iii are then closed by the plugs 4i and 42 and tank cement. The posts are then up-ended, laying the bottom board flat. The anchor members 53 are then inserted in the transverse openings 54 at the upper ends of the posts, and the stud bolts 39 are inserted in the axial bores 5i to threadedly engage in the sockets of the anchoring members. The top of the post is then smeared with tank cement and the inner stringers 29 and 29 are applied to the upper ends of the posts so that the stud bolts project through the openings 55 there- The roof boards are then put in place on the stringers. The Washers 58 are then inserted over the projecting ends ofv the stud bolts to bear against the roof boards, after which the nuts 51 are applied and screwed tightly against the washers to draw the ends of the posts into sealing contact With the stringers 28 and 29. The clamping stringers 64 and 65 are then mounted on the tank, after which the washers 61 and nuts t8 are applied to draw them into cooperative clamping contact with the roof boards. may then be applied to complete the assembly of the stringers. The recesses in the ends of the anchoring members are then closed by the plugs and tank cement, in the same manner as previously described in connection with the lower anchor members 33. the staves composing the wall 2 may be assembled around the peripheral edges thereof and The stud bolts 69V After assembly of the heads Y' secured in position by the hoops, as in conventional practice.

From the foregoing, it is obvious that the shoring which includes the pairs of posts is readily assembled, and is effective in meeting both internal and external pressures. t is also obvious that the metal parts composing the ties are hermetically sealed from the contents of the tank.
