In the figure, reference numeral 1 is a formwork unit for intersections, and as shown in FIGS. 3 and 4, four U-shaped members 2 formed by bending a rigid material such as wire into a substantially U-shape are used. It is formed by connecting the vertical portions 3 of the adjacent U-shaped members 2 with each other through a haunch form frame 4 made of a wire mesh or the like. In other words, by supporting both ends of each wire material forming the haunch form 4 around the vertical portion 3 of the adjacent U-shaped member 2 in a rotatable manner, the haunch form 4 is assembled. An intersection formwork unit 1 is formed. The intersection formwork unit 1 is normally manufactured in advance in a factory, and is folded inward from each of the vertical portions 3 located on arbitrary diagonals to be brought into a flat state and brought into the site, and then, as shown in FIG. It will be expanded and used as follows. It should be noted that reference numeral 5 in FIG. 4 denotes an end portion of the frame body mold inserted when the frame body mold is assembled as described later.

Therefore, in the work for forming the method frame at the site, first, the carried-in intersecting frame unit 1 is expanded and placed at each predetermined intersecting point position shown in FIG. After a while
As shown in FIG. 1, by connecting the end of the frame body mold 5 to the portion of the U-shaped member 2 of each intersection mold frame unit 1, they are adjacent to each other via the frame body mold 5. Forming the formwork for the normal form in sequence by connecting the formwork units 1 for intersections. In this case, U of the intersection formwork unit 1
As a concrete connecting means of the frame form 5 to the part of the character-shaped member 2, for example, as shown in FIG. 4, the ends of the respective wire rods forming the frame form 5 are U-shaped. A simple connecting method is used, such as inserting the wire between the wire members of the haunch frame 4 in the vicinity of the plate-shaped member 2 and further binding them together with a wire or the like. As described above, in the present invention, since the frame form 5 is installed in the intersection form unit 1, the installation work is extremely simple. In addition, since the haunch formwork 4 is incorporated in the intersection formwork unit 1 in advance, the laborious work of attaching the haunch formwork in the field can be omitted, and the workability is extremely good. In addition, 6 in FIG. 1 is a space | grip holder used for the frame 5 for frames, and 7 and 8 in FIG. 2 are rebars.

When the form forming work has proceeded to the state shown in FIG. 1, longitudinal and horizontal reinforcing bars 7 and 8 are arranged on the space holder 6 as shown in FIG. Placing work such as concrete or mortar is performed. In this case, the haunch portion is formed completely integrally with the other frame portion and the intersection portion, so that an extremely strong haunch portion is formed and the original function as the haunch portion can be surely fulfilled. .

In the above description, the intersection formwork unit applied to the intersection of the vertical frame and the horizontal frame has been described, but the T-shape or the L-shape which is located at the side end portion as the normal frame is described. In the case of applying to the intersection part of, or when a diagonal frame body is added to the intersection part, the number of the U-shaped member 2 and the haunch form 4 is increased or decreased correspondingly, and their widths are changed. Needless to say, this can be dealt with by adjusting the shape of the intersecting frame unit by changing it. Further, the specific configurations of the U-shaped member 2, the haunch mold 4 and the frame body mold 5 themselves, and the connecting means of the frame body mold 5 can be changed. The point is that a plurality of U-shaped members 2 having a shape that is substantially the same as the cross-sectional shape of the frame body frame, and a haunch frame 4 that intervenes between these U-shaped members 2 and connects them.
