One end of each longitudinal reinforcing rod a12 and b13 is connected to the upper and lower sides of the side beam, respectively, and the other end is fixed to the long reinforcing rods a10 and b11. The long reinforcing rods a10 and b11 are of the same length, and the longitudinal reinforcing rods a12 and b13 are of the same length.
