Title:
ONE-WAY SLOPING RIGID-FRAMED STRUCTURE AND PRETENSION INTRODUCING METHOD
Document Type and Number:
Japanese Patent JP3768228
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a one-way sloping rigid-framed structure in which proper inward pretension is introduced into high and low supports.
SOLUTION: This one-way sloping rigid-framed structure is composed of a unit frame 1 in which an angle brace 16 is laid between the high support 11 and a diagonal beam 13, and in which a lower end of a compressed material 17 elongated downward from a vertex 15 formed by making the diagonal beams 13 and 14 butt against each other, and the respective diagonal beams 13 and 14 are connected together by means of inclined tension members 18 and 19. In the one-way sloping rigid-framed structure, the compressed material 17 and the tension members 18 and 19 are displaced by pushing up the lower end of the compressed material 17 from a downward direction, in a state in which the tension members 18 and 19 are temporarily fastened to the lower end of the compressed material 17 and the diagonal beams 13 and 14; the inward pretension PT is generated on the high support 11 and the low support 12 via the diagonal beams 13 and 14, the vertex 15 of which is pushed up by the displacement of the compressed material 17 and the tension members 18 and 19; and the tension members 18 and 19 are finally fastened to points on the lower end of the compressed material 17 and the diagonal beams 13 and 14, so that the inward pretension can be introduced into the high support 11 and the low support 12.
