Definitions

  • the present invention relates to a means for preventing deformation of steel tubes having a large diameter.
  • prevention of deformation of steel tubes having a large diameter which may be attributed to statical and dynamic stresses while the tubes are being stored in piles or being transported was achieved by placing intersecting beam members or braces within the tubes at the ends thereof.
  • Such beams had a predetermined size and were defective in the following points. Since the beams are forcibly beaten into the tubes, the operation is not smooth and the removal of the same is difficult. The end parts of the tubes are more likely to be subjected to damages.
  • the present invention has been contrived to eliminate such defects in the prior art cross-type braces for preventing deformationof the steel tubes.
  • FIG. 1 shows a front view of a steel tube in which means for preventing the tube deformation embodying the present invention is placed;
  • FIG. 2 is an enlarged view of the part A in FIG. 1 perspectively showing the dismantled structure of the removable seat and the beam member;
  • FIG. 3 is an explanatory diagram showing the manner in which the said part of FIG. 2 is fixed to the tube;
  • FIG. 4 is an enlarged view of the part B in FIG. 1', perspectively showing the structure of the fixed seat and the beam member;
  • FIG. 5 is a front view of a steel tube in which modified means for preventing the tube deformation also embodying the present invention is shown;
  • FIG. 6 is an enlarged view of the beam (1c) shown in FIG. 5;
  • FIG. 7 is a diagram showing the steel tubes shown in FIG. 5 in storage in piles.
  • two beams la, lb are intersected at the middle of the respective ones in a cross shape, the crossed portion thereof 2 being fixed with each other by nails 3.
  • the angle of intersection of the beams la, lb is determined dependent on the kind of steel tubes such braces are intended for.
  • the number of beams to be used is not limited to two, but more than two beams may be used.
  • fixed seats 4 are provided respectively with a concave 6 which receives a projection 5 projecting from one end of the beams 1a, lb.
  • the projection 5 and the concave 6 are fixedly nailed with nails 7.
  • the said seats 4 are thus attached to the beams la,lb in a perpendicular fashion of the longitudinal direction of the beams,
  • ' 9 denotes seats removably attached to the other end of the beams la, lb.
  • the removable seats 9 are provided withconcaves 11 at its proximate center on both sides thereof to engage with the groove 10 at theends of the beams la, lb.
  • Said seat 9 is attached in a perpendicular fashion in respect of the iongitudinal direction of the beams 1a, lb.
  • the parts 12 to be pressed into contact with the inner surface of the steel tubes have the same curvature as that of the part 8 of said seat 4.
  • FIG, 7 shows steel tubes in storage.
  • the weight of the upper tubes bear on those in the lower side particularly at the portions where the tubes contact with each other, that is at. the parts which may correspond to the hours of l, 3, 5, 7, 9 and 11 in terms of hour angle. (Indicated by the arrows in FIG. 7).
  • I j I I
  • another beam 10 is added to the intersecting beams 1a, lb shown in FIG. 1.
  • Three pieces of beams may be intersected at random or the manner as shown in FIG. 5 may be employed, wherein the third members 10, 1c are fixed to the previously intersected and fixed two beams la, lb.
  • the ends 15 ofthe third beams 1c, 1c are formed like an arrowhead so as to allow engagement with the other beams la, lbat the intersecting part.
  • the other ends-16, 16 to come into contact with theinner surface of the steel tubes are arranged in the like manner as shown in FIGS. 2 and 3 for attaching wedges andseats.
  • the means for preventing deformation of steel tubes having alarge diameter of the present invention is attached to the steel tube in the folllowing manner.
  • the beams'la, lb provided with removable seats 9, 9 are inserted into a predetermined position within the tube and parts 8, 8 of the fixed seats 4, 4 are contacted with the inner surface of the steel tubes.
  • wedges l3, 13 are forced between the bottom of the removable seat 9 and the bottom of the grooves 10 one on each side thereoffacing each other by means of a proper tool such as mallet. Wedges are driven in until the contacting portions of the removable seats 9 come into close contact with the inner wall surface of the steel tube.
  • three beam members are to be equipped within the steel tube as shown in an embodiment of FIG.
  • the additional beams 10, 1c are attached at the sides of the intersecting portion of the beam la, lb by means of the removable seats 9, 9 and the wedges l3, 13 to achieve a shape of three beams intersecting.
  • the contacting portions l2, 12 of the removable seats 9, 9 into close contact with the inner wall of the steel tube by means of the wedges l3, 13, due attention must be paid so that the fixed seats 4, 4 connected to the lower portion of the beams la, 1b may come in close contact with the inner wall of the steel tube.
  • Such may be achieved by adjusting the wedges as they are driven in from the fore and the rear of the seats 9, 9.
  • the novel means for preventing deformation of steel tubes having a large diameter in accordance with the present invention offers an easy and rapid provision and removal of the means within the steel tube. It also facilitates attaching the means at any desired position within a steel tube since one of the seats may be adjusted by the wedges such as at the center of the length of the pipe and to correspond the shapes of the means to the allowable variation of the sizes in steel tubes. It also secures pressing and setting the contacting parts of the seats at the ends of the beams within the tubes thereby completely eliminating the slipping of the means during the the handling or the transportation. It also eliminates possible irregular or local pressure at the contacting parts.
  • the back of the seats are so curved in a corresponding curvature ratio to that of the inner wall of the tubes so as to increase the contacting area of the means with the inner surface and to relieve the concentration of local stress.
  • This will achieve prevention of deformation of the steel tubes at the part where such beams contact with the steel tube.
  • the embodiment shown in FIG. shows a structure which gives extremely strong resistance against deformation caused by the external force when the tubes are stored in piles.
  • the steel tubes are merely to be piled so as to allow the beams within the tube to form a straight line in order to achieve this purpose.
  • wedge means inserted. between engaging parts of each of said beams and its respective removable seat to adjust the position of said removable seats relative to said other ends of said beams;
  • said removable seats each having a groove formed along two opposite peripheral edges thereof, and wherein said beams each have a pair of elongated portions extending lengthwise of said beams and slideably engageable with saidv grooves of the respective removable seats, said wedge means being inserted between said elongated portions and between respective beams and removable seats.
  • Apparatus according to claim 1 comprising a third beam attached to the intersecting parts of said at least two beams and intersecting said at least two beams at an angle of about 120;
  • each wedge means includes a pair of oppositely directed wedges.
  • Apparatus according to claim 4 comprising at least two additional beams intersecting and associated seats and wedge means at substantially the other end of said steel tube.
