Title: Manufacture of hume concrete pipe
Inventor: MATSUMURA TAKEFUMI
IPC: B28B21/96
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To manufacture Hume concrete pipes, in which their inside diameters and inner faces are uniformly finished, in a short period of time by thickly forming a mortar and a paste layers having fine particles suitable for the cutting on an inner face of each Hume concrete pipe and finishing the inner face composed of the mortar and paste layers so as to have a predetermined wall thickness by cutting work after curing and hardening. SOLUTION: After concrete using early-strength cement whose particles are fine is cast into a formwork having therein a reinforced cage and centrifugal molding is performed by a centrifugal pipe making machine according to conventional procedure, the concrete is cured and hardened to be released from the form. Thereafter, an inner face consisting of a mortar and a paste layers 2, 3 is machined by cutting work so as to have a predetermined wall thickness to make a product. In this case, a circular ring of the formwork has a concrete containing portion whose depth is formed deeper than that of a conventional form so that the thickness of the paste layer W2 becomes 4-10mm, and the cutting work is performed in a range of the thickness of the paste layer W2 so that the wall thickness has a predetermined size.  Accordingly, spatula work can be eliminated to shorten manufacturing time, and the productivity of Hume concrete pipes having a small bore diameter can be improved.

Filed: 1989-02-28
Abstract: PURPOSE:To take a measurement with high accuracy by suspending an extensometer from an upper gripper by a 1st spring and providing a 2nd spring which has a spring constant equal to that of the 1st spring between a lower gripper and the extensometer. CONSTITUTION:A test-piece TP is clamped between the upper gripper 13 fitted to a fixed wall 11 through a load cell 12 and the lower gripper 14 coupled with a load mechanism. Bolts 23 and 24 are adjusted to align the center of the extensometer with the center of a gauge mark and when the overall elongation of the test-piece TP which is being loaded is uniformed, the center of the gauge mark moves down by 50% of the overall elongation. Here, the springs 27 and 28 are equal in spring constant, so the system of the springs 27 and 28 and the extensometer 50 has the same behavior of elongation with the test- piece TP. The center of the extensometer 50 moves down by about 50% of the elongation quantity of the test-piece TP. Consequently, upper and lower levers 51 are opened spreading downward symmetrically about the center line of the extensometer 50 and the tip of the levers 51 do not deviate from the gauge mark, so that elongation is measured with high accuracy.
