The invention provides a method and apparatus for efficiently manufacturing a body structure block by welding long extruded hollow shape members. A plurality of support beds (10) are arranged along the longitudinal direction of the long works. Each support bed (10) is composed of six supporting units (30) capable of being moved along the width direction (Y) of the body structure block, and clamp units (40,50) disposed at left and right ends thereof. The supporting units (30) support the butted portions (joints) of seven works. Both ends of the work are clamped by the clamp units (40,50). The support units (30) and the clamp units (40,50) are equipped with expansion devices (34), through which the heights for supporting the works mounted thereon are adjusted. Adjacent supporting units (30) are coupled via coupling units (60), and the inclination angle of each supporting unit (30) can be controlled by the expansion of the coupling units (60). Thus, the heights and inclination angles of supporting units (30) supporting the works can be controlled, facilitating manufacture of the body structure block. <IMAGE> |
