Abstract
Containers such as tanks, bins, cylinders, and the like, are constructed from a plurality of arcuate sections. The sections are formed on the ground, or other support surface, and lifted therefrom in a suitable manner to cooperate with other like sections during erection of the containers. Each section is formed by a plurality of strips laid on a concave jig so as to conform thereto. Beams reinforce the strips, which are tied together as by welds, and the like, to form a sheet. Shapers are advantageously removably attached to the sections for holding same to a required shape until the sections are connected together, and for holding adjacent sections in position relative to one another until suitable connection between the sections is made.
Claims2
A method for constructing a container comprising a skin formed of plates connected to each other in overlapping relation and having reinforcing beams, comprising the steps of:
- a. placing a plurality of sheet strips in overlapping fashion on a jig having a semi-cylindrical concavity;
- b. permitting the weight of the sheet strips to curve and conform the strips to the concavity and form an arcuate sheet;
- c. attaching beams to the arcuate sheet for reinforcing the arcuate sheet;
- and
- d. connecting together of a plurality of reinforced arcuate sheets to form a generally cylindrical container.
