- the taper angle and the wall thickness ratio it is possible to obtain a skeleton block that is excellent in load resistance and loading efficiency even at a thinner wall thickness. That is, since the thickness of the skeleton block can be reduced, a skeleton block having excellent cost and weight reduction and excellent strength in the vertical direction can be obtained.
- radial ribs are provided below the column end protrusions 27a for all combinations of skeleton blocks that have obtained good results.
- a vertical load of 31 kN / m 2 was applied for 1 year, and the dents on the tip end of the column were As a result of the investigation, it was found that the rib formed on the lower side of the columnar tip protrusion 27a was not deformed even after one year and the creep resistance was improved.
- the thickness of the ribs is 3.0 mm x 8 and the total thickness is 24 mm. This is about 20% of the circumferential length of about 140 mm at the rib installation position at the end of the column used for the test. Become. In other words, if the total width of the ribs is 20% or more of the total circumference of the support tip (rib arrangement position), high creep resistance can be obtained. In this case, the number of ribs is desirably 8 or more. This is because the effect of dispersing stress increases as the number of ribs formed on the circumference increases. In the above-described conditions, the rib may be 6 mm or thicker.
- ribs instead of forming a plurality of ribs at equal intervals, they may be formed on the entire circumference (that is, a rib having a thickness of 100% of the total length of the support tip portion).
- angle of the rib is not specified, it is preferably 45 degrees or more and 80 degrees or less with reference to the horizontal plane, but more preferably 60 degrees or more and 75 degrees or less.
