FORM WORK METHOD FOR REINFORCED CONCRETE BEAM, WALL, ETC., AT JOINT SECTION IN VERTICAL DIRECTION AND GUIDE METAL FITTING USED IN THE METHOD

摘要

PURPOSE: To make a reinforced concrete beam difficult to be rusted and cracked from its joint section, and also make the joint section assembled at low cost and rather easily. ;CONSTITUTION: In a form work method for reinforced concrete beam at joint section, one more set of star lap 10' is positioned at a joint position, and multiple guide metal fittings 20 in which a cross-recessed section 22 is formed for guiding a cleat 28 between the forms are installed around both star laps 10 and 10' so that they are bridged to the two star laps 10 and 10'. Also partition forms 26, 27, and 27a are installed at that section in the area surrounded by the star laps 10' at the joint position. Next, as a partition form for a covered thickness of the star lap 10', the cleat 28 is inserted between a side form 5 and beam bottom form and the cross-recessed section 22 of the guide metal fitting 20 fixed to the star laps 10 and 10', respectively, and then fixed. Finally, the cleat 28 is inserted into the cross-recessed section 21 of the guide metal fitting fixed at the top of the star lap 10', and then fixed.;COPYRIGHT: (C)1993,JPO&Japio
