CONSTRUCTION METHOD FOR SUPPORT SECTION OF PRECAST (PCa) FLOOR SLAB

PROBLEM TO BE SOLVED: To make a simple means prevent a gap from being made in a support section by the camber or distortion of a precast floor slab or the unevenness of a top surface of a floor slab supporting member, when the precast floor slab is placed on the floor slab supporting member. SOLUTION: A member, wherein a support plate 11 and a support mortar injection bag body 20 are stacked, is interposed in the support section 12 of the precast floor slab 10; the precast floor slab 10 is placed on the floor slab support member composed, for example, of a steel elastic beam 30, and temporarily fixed in a supporting attitude by adjusting height; shoe mortar 22 is injected into the bag body 20 from a mortar injection port 21; the bag body 20 is expanded so as to be brought into close contact with the top surface of the floor slab supporting member and an undersurface of the support plate; and after the mortar in the bag body 20 is hardened, the temporarily fixed member is removed, so that the precast floor slab 10 can be placed.
