[0020]

As described above, by using the support device for a beam formwork with a wall according to the present invention, the beam of the beam form support tool fitted and locked to the upper end of the wall formwork using the fitting portion. Since the under-beam formwork and the side-side formwork can be supported by the formwork supporting portion, the support for supporting the under-beam formwork on the floor surface becomes unnecessary, but particularly according to the configuration of the present invention. The upper vertical column of the wall form retainer connected to the beam form support is brought into contact with an outer surface of a connecting portion between the main panel for wall form and the auxiliary panel, and a lower end of the upper vertical column. Since the lower vertical pillar portion which is connected to the inside and hangs down is accommodated inside the main panel for the wall formwork, the horizontal material used for connecting the main panel to the separator is provided on the lower side. Just by arranging it at a position overlapping the vertical column, the upper vertical column and the beam form support connected thereto are fitted. An auxiliary panel and parts can be held in extended vertical position of the main panel.

Therefore, even if the height of the auxiliary panel is relatively large, there is no need to perform a mold assembly operation for holding the lower main panel in the extended vertical position by using a separator together with the auxiliary panel as in the related art. Therefore, the cost required for assembling the form can be significantly reduced. In addition, the vertical distance between the upper end of the lower vertical column of the wall form holder and the fitting portion of the beam form support can be adjusted to the minimum necessary in accordance with the height of the auxiliary panel. In comparison with the case where the length of the upper vertical column of the wall form holder is increased according to the maximum height of the auxiliary panel, the lower vertical column is always arranged closer to the upper end of the main panel. As a result, it is possible to dispose the main panel lateral member, which must be disposed at a position overlapping with the lower vertical column portion, close to the upper end of the main panel, and effectively separate the separator and the mold. A highly secure wall form can be assembled using the frame fastening hardware.

According to the configuration of the second aspect, it is easy and easy to adjust the vertical distance between the fitting portion of the beam form support and the upper end of the upper vertical column of the wall form holder. In addition, the structure can be simplified, and the entire apparatus can be configured at low cost. According to the configuration of claim 3, at least the lower half of the connecting pillar portion of the beam form support after removing the wall form holder from the beam form support at the time of dismantling the form. Utilizing the space between the wall formwork (upper end of the main panel) and the horizontal form for removing the main panel of the wall formwork from the separator, the formwork disassembly work can be performed. Easy and efficient.

The side 9a of the connecting pillar 9 on the side of the wall form 8 of the beam form support 2 is made vertical, and a relatively wide space is formed between the side 9a and the wall form 8 over its entire length. However, by inclining the side 9a as in the above-described embodiment, the mounting strength of the connecting column 9 can be secured while securing the space necessary for the horizontal movement of the main panel 6. (Weld strength) and bending strength. Of course, the side 9a can be formed in a step shape. The structure in which the connecting column 9 and the upper vertical column 13 of the wall form holder 3 are removably connected to each other in a vertically adjustable connection position is not limited to that of the above embodiment.
