PROBLEM TO BE SOLVED: To make a latticed point part inexpensive by employing a simplified structure in which the panel point part is directly connected to a floor slab, and to enable cost reduction and the shortening of a construction period by enabling the elimination of troublesome adjustment in construction. SOLUTION: An erection unit 17 comprises: an upper latticed point box 4 which has a perforated steel plate dowel 9, which is directly connected to an upside concrete floor slab 10, and in which an upper latticed point part 3 is constituted by fixing upper ends of two diagonal members 2 arranged in a truncated-chevron shape in a lower part; one lower latticed point box 6' which has a perforated steel plate dowel 15, which is directly connected to a downside concrete floor slab 16, and in which a lower latticed point part 5 is constituted by fixing a lower end of either of the two diagonal members 2; and the other lower latticed point box 6 which has the perforated steel plate dowel 15, which is directly connected to the downside concrete floor slab 16 via the dowel 15, and in which the lower latticed point part 5 is constituted by fixing a lower end of the other one of the two diagonal members 2. The lower latticed point boxes 6 and 6' on the approach sides of the erection units 17 adjacent to each other are joined to each other so as to constitute the lower latticed point part 5.
