Fig. 17 is a schematic sectional view showing another example of the portion "D" where the mold frame is supported at the upper end portion of the side wall portion in Fig.

As shown in FIG. 17, the support 121 is formed such that a plurality of angles 121a, 121b, and 121c are integrally connected to each other at an end thereof, or one side of the support 120 is overlapped with each other to form two angles 121a and 121b 10A, except that an insertion groove portion 122f region is formed between the upper surface and the lower surface.

The lower end of the angle 121c formed on the lower side of the supporter 121 may be fastened to the side wall 20 through a fastening means 50 such as a pin or a bolt, Of course.

Fig. 18 is a schematic cross-sectional view showing another example of the portion "D" where the mold frame is supported at the upper end portion of the side wall portion in Fig.

18, the end of the lower support 63-1 of the "L" -shaped angle 64 is welded to the side wall 20 to form the "L" 10 is the same as the embodiment of Fig. 10, except that the space between the angles 64 of the protrusions is an area of the insertion groove 122g.

Here, although the fastening means shows an example of welding, it may be a fastening means such as a bolt or a pin, or a binding means such as a wire.

15 shows an example in which the "L" -shaped angle 64 is coupled to the inside of the side wall portion 20, but the upper side or the vertical projection 26 (see FIG. 15) of the side wall portion 20, It can be welded to the inner side of the inner tube.

Fig. 19 is a schematic sectional view showing still another example of the "D" portion in Fig. 8 where the mold frame is supported at the upper end portion of the side wall portion.

As shown in Fig. 19, the lower end of the "U" -shaped angle 65 is welded on the support base 121, so that the "U" -shaped angle 65 itself becomes the region of the insertion groove 122h Is the same as the embodiment of Fig.

Here, in the illustrated example, although an example of fastening by welding is shown, coupling means such as bolts or pins can be used, and the type of the fastening means is not limited in the present invention.

In the illustrated example, the lower end of the U-shaped angle 65 is coupled to the support 121, but it is to be understood that the U-shaped angle 65 may be welded to the inner side or the upper side of the side wall 20.
