Definitions

  • ABSTRACT Structural components are provided which are particularly suitable for assembling cylindrical structures such as chimneys.
  • the components include an elongated beam having a generally l-l-shaped transverse cross section and a relatively short joint which also has a generally H-shaped transverse cross section.
  • the beam includes longitudinally extending generally parallel flanges which are joined by a web portion, and each end of each flange is provided with longitudinal slots adjacent each side.
  • the web may also be provided with a longitudinally-extending slot at each end.
  • the joint also includes spaced apart generally parallel flanges joined by a web portion.
  • the structure is assembled by arranging a row of beams side by side and inserting the joints so that flanges thereof extend generally perpendicularly to the flanges of the beams and are received in the slots thereof.
  • the joints may be secured to the beams, and thereafter another row of beams can be arranged end to end with the first row and joined thereto by the joints.
  • the present invention relates to a cylindrical structure.
  • the present invention relates to a cylindrical structure to be used as such superhigh chimney.
  • An object of this invention is to overcome difficulties in the structure of chimneys as well as problems encountered in constructing tall chimneys.
  • the cylindrical structure in accordance with this invention comprises H-shaped steel members arranged in a polygonal form and joints of I-I-shaped cross section interconnecting the H-shaped steel members in horizontal direction and joining the same together also in vertical direction, each of the I-I-shaped steel members having an inner flange smaller than an outer flange thereof in width and formed at each end thereof with cutouts having a depth of at least half the length of the joint, the flanges of adjacent I-I-shaped steel members being in butting contact with each other, the joints being fitted into upper and lower I-I-shaped steel members with the cross sectional planes of the flanges intersecting the upper and lower steel members.
  • each of the H-shaped steel members constituting the wall sustains those positioned thereon with respect to the weight acting as vertical force and, as for a horizontal force, each of the H-shaped steel members absorbs the resulting stress when the steel member flexes. Since the junction of the I-I-shaped steel members where they are joined in longitudinal direction includes the joint which is positioned in a different direction from the I-I-shaped steel members but is substantially identical therewith in section, the junction has a very high strength and good resistance to stress such as torsion. The butting contact between the end faces of the H-shaped steel members gives an excellent bond whereby load will be directly transmitted.
  • cylindrical structure which comprises a mere combination of the I-I-shaped steel members and joints is extremely easy to construct, saves labor and can be completed in a remarkably shortened period of time.
  • FIG. 1 is a front view showing a structure in accordance with invention which serves as a chimney;
  • FIG. 2 is a front view on an enlarged scale showing portion A of FIG. 1;
  • FIG. 3 is a sectional view taken along the line IIIIII in FIG. 2;
  • FIG. 4 is a sectional view taken along the line IV IV in FIG. 2;
  • FIG. 5 is a sectional view taken along the line V V in FIG. 4;
  • FIG. 6 is a plan view showing an I-I-shaped steel member to illustrate how the opposite side edges are to be cut off;
  • FIG. 7 is an enlarged perspective view showing the end to be joined of the H-shaped steel member
  • FIG. 8 is an enlarged perspective view of a joint
  • FIG. 9 is a sectional view corresponding to FIG. 4 and showing another embodiment of this invention.
  • FIG. 10 is an enlarged perspective view showing the end to be joined of the I-I-shaped steel member in FIG. 4.
  • FIG. 1 shows a chimney I including H-shaped steel members 1 arranged in a polygonal shape and joints 2 I-I-shaped in cross section and joining the H-shaped steel members 1 in vertical direction, the
  • joints 2 being interconnected in an annular form.
  • the lower portion of the chimney 3 is secured to a base 5 provided with anchor frame 4.
  • the H-shaped steel member 1 includes a web 6 and flanges 7 and 8 and, for application as an constituent element of chimney, the steel member is so dimensioned by cutting off that the inner flange 8 is smaller than the outer flange 7 in width.
  • the amount to be removed by cutting off depends on the diameter of chimney 3 to be constructed.
  • FIG. 6 show the portions 8a to be cut off for removal which are positioned outside the lines r and r, extending from the center 0 of the chimney 3 to the outer corners of opposite edges of outer flange 7 of the H-shaped steel member 1 to be used as the wall material of the chimney. Where the diameter of the chimney 3 is small, portions 7a of the outer flange '7 outside the lines r and r are also removed by cutting off.
  • the I-I-shaped steel member 1 thus machined is then formed, at each of its opposite ends, with a cutout 9 in the web 6 at the center of width thereof, with cutouts l0 and 11 formed in the opposite edges of the flanges 7 and 8 in facing relationship, each of the cutouts 10 and 11 being exposed at one side thereof.
  • the joint 2 for connecting the H-shaped steel members in longitudinal direction is H- shaped in cross section and includes flanges 13 with a web 12 interposed therebetween. Both flanges 13 are brought closer toward each other inwardly so as to be in conformity with the lines r and r shown in FIG. 6.
  • the depth of the cutouts 9, l and 11 in the I-I-shaped steel member is half the length of the joint 2 or greater.
  • the lower half of the joint 2 is fitted concentrically to the end of the I-I-shaped steel member to be joined therewith by utilizing the cutouts 9, 10, 11 therein, with the web of the joint 2 at a right angle with that of the I-I-shaped steel member.
  • the joints 2 are joined together in an annular form by means of rivets 14 as shown in FIGS. 4 and 5.
  • high tension bolts may of course be used, or connection may be achieved by welding.
  • the joints are secured by bolts, it will be understood that the flanges thereof will be provided with both openings (not shown in FIG. 8).
  • the I-I-shaped steel members 1 are joined with the joints 2 respectively and the steel members are arranged in a polygonal form. As illustrated in FIG. 2, the junctions of the flanges 7 and 8 of I-I-shaped steel members 1 with the flanges 13 of the joints are welded together, the welds being indicated at 15.
  • an H- shaped steel member 1 having an end of the same shape as that of the I-I-shaped steel member 1 already joined with the joint 2 is assembled with the upper half of the joint 2, whereby the webs 6 and flanges 7 and 8 of the upper and lower l-I-shaped steel members 1 are brought into butting contact with each other respectively.
  • the depth of the cutouts 9, 10, 11 in both H-shaped steel members 1 may preferably be slightly greater than half the length of the joint 2.
  • the upper H-shaped steel members 1 are also joined with the joints 2 one after another into a polygonal form.
  • the butting portions of the flanges of the upper and lower H-shaped steel members 1 are welded together, and the junctions of the flanges 7 and 8 of the upper H-shaped steel members with the flanges 13 of the joints 2 are also welded, the welds being indicated at 16 and 17.
  • the upper and lower ends of the chimney 3 are provided with joints 18 and 19 which are respectively connected together into annular form.
  • the joints at the lower end are further connected to the anchor frame 4 extending from the base 5.
  • the joints 18 at the upper end of the chimney 3 may be half the length of the other joints 2, but they may be of the same length as the other joints 2 in the case where a platform or a portion having a smaller diameter is to be mounted at the upper end.
  • the platform or the like is welded to the upper half portions of the joints which are left projected.
  • the joints 19 at the lower end may preferably be longer than the other joints 2, since they are secured to the base 5.
  • assemblage begins at the base and the joints 2 and the I-I-shaped steel members 1 are joined together alternately, with assembled structure progressively lifted upward by building up for successive joining operation.
  • the joints 2 may be firmly joined together in an annular form beforehand in the factory and the resulting assembly is then fitted into I-I-shaped members at a construction site, this operation being carried out repeatedly.
  • the cutouts 9, l0 and 11 in the I-I-shaped steel member serve as a guide when the web 12 and flanges 13 of the joint 2 are fitted therein, so that assemblage can be conducted smoothly and readily, with joining errors minimized.
  • the joints 2 are very firmly joined together in an annular form, it is possible to eliminate welding between adjacent H-shaped steel members. Since the overall length of the weld will then be reduced a great deal, the construction cost can be reduced.
  • a group of joints 2 having I-I-shaped cross section and interconnected into an annular form corresponds to a bamboo joint, and accordingly, calculation of buckling of column can be made with ease. For this reason, a very strong structure can be obtained.
  • FIGS. 9 and 10 illustrate another embodiment of this invention, which embodiment is characterized in that a joint engages both of adjacent H-shaped steel members.
  • a cutout is not formed in the web 21 of an I-I-shaped steel member 20, but cutouts 23 are provided in flanges 22 in facing relationship, each cutout 23 being positioned midway between each side edge thereof and the portion from which the web 21 extends.
  • the web 25 of a joint 24 is shorter than the web 12 of the joint 2 of the foregoing embodiment and does not intersect the web 21 of the H-shaped steel member 21.
  • Opposite flanges 26 of the joint 24 are fitted into the cutouts 23 of the adjacent H-shaped steel members 20 and the joint 24 and the steel members 20 are welded together. Indicated at 27 are welds.
  • the construction process is simplified the more because there is no need to interconnect the joints 24.
  • this invention makes it possible to construct a strong chimney in a short period of time and at a low cost.
  • a structure comprising a plurality of elongated vertically extending beams and a plurality of vertically extending joints, each beam being generally I-I-shaped in transverse cross section and including a pair of generally parallel generally planar inner and outer elongated flanges having upper and lower ends and a pair of longitudinally extending sides and a longitudinally extending generally planar web extending between the flanges at their approximate midportions and having upper and lower ends, the outer flange being wider than the inner flange, each end of the flanges being provided with a longitudinally extending cutout adjacent each of the sides thereof, each joint being generally H- shaped in transverse cross section and including a pair of flanges and a web extending between the flanges at their approximate midportions, the flanges extending angularly with respect to each other to form an acute included angle therebetween, the beams being arranged in first and second sets of parallel beams, the beams of the first and second sets being generally aligned end-to
