PROBLEM TO BE SOLVED: To provide a pressure receiving structure which has a high degree of production efficiency and which makes possible an easy change in dimension. SOLUTION: The pressure receiving structure J1 is constituted by superimposing the upper beam member 1 and the lower beam member 4 on each other in the up-and-down direction in a state where they cross each other. An insertion opening S used for an anchor is formed at the intersection C of the upper beam member 1 and the lower beam member 4. Then the upper beam member 1 and the lower beam member 4 are each constituted by using a hollow extrusion made of aluminum alloy. The upper beam member 1 consists of a plurality of construction materials 1A, 1A of the upper beam which have been continuously constructed in the width direction. Then the lower beam member 4 consists of a plurality of construction materials 4A, 4A of the lower beam which have been continuously constructed in the width direction. COPYRIGHT: (C)2009,JPO&INPIT
