JOINT BUILDING CONSTRUCTION BETWEEN PRECAST CONCRETE BEAM AND COLUMN WITH CIRCULAR SECTION

摘要

PURPOSE: To simplify the method for constructing a frame of a column and beams and enhance the working efficiency at a site by placing a tensile material passing through commonly sectional insides of joint ends of beams in a circular shape at a plane view, and straining it strongly to produce inward centripetal force. ;CONSTITUTION: Precast concrete beams 3... providing joint ends 2... having a shape dividing a circle large by thickness necessary for joint rather than the appearance of a column 1 to mounting positions of the beams of the column 1 with a circular cross-section are constructed by bringing their joint ends 2 into contact with the circumference of the column 1. After that, a space 4 between each of the joint ends 2 and column 1 is filled with filler. Then, a tensile material 5 commonly passing through sectional insides of the joint ends 2 of the beams 3 is placed in a circular shape at a plane view. After the filler in the space 4 is solidified, the tensile material 5 is strongly strained to produce inward centripetal force, and the beams 3 and column 1 are strongly bound.;COPYRIGHT: (C)1996,JPO
