    • The present invention provides a center frame designed so that a center member, legs, and a lower plate can be formed by bending metal sheets, and to provide a manufacturing method for the center frame.A pair of front legs 13 and a pair of rear legs 14 are formed by bending metal sheets so as to have substantially reverse U-shaped cross-sections. The center member 10 is formed by bending a metal sheet so as to have a substantially square U-shaped cross-section. The front legs 13, the rear legs 14, the center member 10, a center front plate 22, and a center rear plate 23 are placed on and securely weld to the lower plate 18, which has an approximate X shape, in a plan view, and an isosceles trapezoidal shape in a lateral cross-section. This eliminates the need for expensive molds and makes it possible to easily manufacture the center frame from the center member, legs, and lower plate formed by bending metal sheets.
    • 本发明提供了一种中心框架,其设计成可以通过弯曲金属板来形成中心构件,腿部和下部板,并且提供用于中心框架的制造方法。 一对前腿13和一对后腿14通过弯曲金属片而形成为具有基本上相反的U形横截面。 中心构件10通过弯曲金属板而形成为具有大致正方形的U形横截面。 将前腿13,后腿14,中心构件10,中心前板22和中央后板23放置在具有大致X形状的下板18上并且牢固地焊接在平面图 ,横截面为等腰梯形。 这消除了对昂贵的模具的需要,并且使得可以从通过弯曲金属板形成的中心构件,腿和下板容易地制造中心框架。
