  • ABSTRACT PP NOJ ,319 A method of constructing a spherical tank or the like,
  • FIG. 1 is a front view, illustrating the dividing and sub-dividing of a spherical tank constructed in accordance with a prior art method
  • FIG. 2 is a view, showing-a manner of lifting a .circular structural unit prefabricated-in accordance with the prior art method
  • FIG. 3 is a view, showing a manner of lifting a typical structural unit used in the prior art method
  • FIG. 4 is a front view, illustrating one example of the dividing and sub-dividing of a spherical tank constructed in accordance with the present invention
  • FIG. 5 is a view, showing a manner of lifting a largesized structural unit prefabricated in accordance with l the present invention.
  • FIGS. 6 and 7 are perspective views, showing structural units of FIG. 3, on which reinforcements are attached to complete medium-sized structural units;
  • FIG. 8 is a perspective view,-showing oneexample of a large-sized structural unit of the present invention, with reinforcements attached. on r the inner surface thereof;
  • FIG. 9 is a view, showing one example of prodecure for assembling several medium-sized structural units into one large-sized structural unit
  • FIGS. 10 to 12 are perspective views, illustrating examples of a manner of fastening reinforcements on the structural units of the present invention.
  • FIG. 13 is a sectional view, taken along line AA of FIG. 10.
  • the spherical surface of the tank 1 to be constructed is divided into many smaller elements 2 as shown in FIG. 1, and in the field, the smaller elements are set in place one by one, and are thereafter welded in a predetermined order to complete the spherical structure.
  • FIG. 3 shows several smaller elements 2 at joints 4 to accomplish a mediumsized unit 5, and thereafter the medium-sized units 5 are set in place one by one by a crane and are welded at the joints 6 of these medium-sized units.
  • several medium-sized units 5 as above described are welded together on the ground to form a larger, circular unit 7 as shown in FIG. 2, and then the large-sized units 7 are lifted by a heavy duty crane and set in place to construct the tank.
  • the present invention aims at providing a novel method of constructing a spherical tank or the like, by which disadvantages of the conventional methods as described in the above are removed.
  • a method which comprises the steps of prefabricating medium-sized structural units, producing large structural units, in the form of aitriangle or the similar shapes by combining the medium-sized structural units, attaching reinforcements on the peripheral portion of the triangular units, and finally assembling them one after another to obtain a complete structure of spherical tank or the like.
  • FIGS. 4 and 5 the surface of a tank 1 is divided into sections by the equatorial line or other latitudinal line 8 and a plurality of longitudinal lines 9, 10, 11, 12.
  • the large-sized structural unit or block 13 which has an outline defined by the equatorial line or latitudinal line 8 and longitudinal lines 11 and 12 is in the form of a triangle or similar shape.
  • the triangular block 13 has a flat apex.
  • Reinforcements 3 are welded on the block 13 along theblock joints 8, 11 and 12 as shown in FIG. 8, and the reinforcements are arranged also in a triangle or similar shape. Since the reinforcements 3 thus arranged have three points of intersection 19, 20 and 21, any torsional deformation in relation to the three points of intersection can not possibly occur. Thus, at least the portion of the block 13 lying on the three reinforcements 3 holds its shape correctly conforming to a part or segment of a spherical surface, and in addition rigidity of the large-sized block 13 is increased.
  • Spherical shell segment or structural element constituting the large-sized block of FIG. 5 or FIG. 8 are assembled from mediumsized structural units or blocks 14, 15 and 16 of suitable sizes as shown in FIG. 9. These medium-sized structural units are completed on the welding jig in the factory by fiat welding. Then, these medium sized blocks 14, 15 and 16 are welded together to form a large-sized block 13.
  • the large-sized block thus constructed is of an extremely small thickness in comparison with its relatively large surface area, and therefore its rigidity is extremely low as it is. As a result, handling such as transportation, inversion and mounting of the block would be very difficult and dangerous.
  • reinforcements in a correct form are temporarily attached on a large-sized block which has been prefabricated on the assembling jigs, and thereby not only the portion of the block adjacent to the reinforcements but also the portion far away from the reinforcements can be reformed into correct shape.
  • Such block fabricated as above is by far more correct in its shape than one that is fabricated by the assembling jigs alone.
  • the large-sized block is imparted with a high rigidity not only in the region adjacent to the reinforcement but also all over the block, so that handling such as transportation, inversion or field mounting of the large-sized block can be done with ease.
  • the reinforcements 3 it is preferable to designthe reinforcements 3 in such that their shape on construction may not be affected by the heat, if it is repeatedly experienced to attach them on the block by way of welding and to detach therefrom by way of gas cutting or thejlike.
  • an attachment piece 18 is fixed to the reinforcement 3 by means of such as bolts 17, as shown in FIGS. to 13, so that the attachment of the reinforcements 3 on the block 13 may be accomplished by welding the attachment piece 18 on the spherical surface of the block 13.
  • Such arrangement would be economically advantageous, since the reinforcements can be used semipermanently.
  • the reinforcements 3 of the present invention can be attached to the inside of the spherical surface as shown in FIG. 8, or alternatively to the outside of the spherical surface as shown in FIG. 5, according to the requirecan be employed, if it provides convenient mounting and dismounting of the blocks. In case of constructing a spherical tank, however, it is preferable to attach the reinforcements to the inside of the lower hemisphere, while it is preferable to attach the reinforcements to the outside of the upper hemisphere.
  • the reinforcements are fixedly interconnected to eachother at the joints where they intersect with each other, but they may be interconnected other than in a fixed manner, taking into consideration theconvenience in dismounting the reinforcements.
  • a method of constructing a tank or the like in the form of a sphere having an equatorial line and several longitudinal lines comprising the steps of prefabricating large-sized blocks of a triangular shape with a surface conforming to a segment of a spherical surface, the outline of each block extending along the equatorial line and plurality of the longitudinal lines of the segmental spherical surface, welding connecting pieces to the segmental spherical surface of said blocks and bolting triangular reinforcements to said connecting pieces to thereby temporarily attach the same, and assembling these large-sized blocks by .welding along the longitudinal lines and the equatorial line to complete the structure, and, after assembling the blocks, removing the reinforcements.
