METHOD OF TREATMENT CONSTRUCTION OF VERTICAL JOINTING OF SURFACE OF SUCCESSIVE POUR OF REINFORCED-CONCRETE CONSTRUCTED SLAB

摘要

PURPOSE: To prevent the generation of the damage of a wire gauze and the outflow of concrete and cement paste even when vibrations required when precedently placed concrete is placed are applied by reinforcing the wire gauze by using a steel rod with a leg and a frame body, on which a wire gauze having dense meshes is mounted. ;CONSTITUTION: A lower jointer 9 displaying the boundary surface of the jointing of successive pours is installed horizontally to the bottom forms of a slab, and a steel rod with legs consisting of one steel rod 2 and a plurality of the legs 3 is set up horizontally to the bottom forms along the lower jointer 9. A lower end reinforcement 10 is arranged so as to pass a section just above the legs 3, and bound with the steel rod 2 and fixed, and an upper end reinforcement 11 is arranged in parallel with a section just above the lower end reinforcement 10. A frame body consisting of a plurality of vertical steel rods 5, one horizontal steel rod 7 and a wire gauze 6 having dense meshes is inserted from an upper section along the steel rod with the legs, and the horizontal steel rod 7 is bound with the upper end reinforcement 11 and fastened, thus forming the vertical surface of the wire gauze 6. The wire gauze is installed additionally to a section 12, on which no wire gauze is mounted and which is surrounded by the upper end reinforcement 11, the lower end reinforcement 10 and the two vertical steel rods 5. Accordingly, the concrete performance of the surface section of the jointing of successive pours can be improved.;COPYRIGHT: (C)1995,JPO
