An outer auxiliary frame 35 is fixed in advance with nails or the like via a wooden frame 36, and the outer auxiliary frame 35 is arranged so as to be in contact with the side surface of the side frame or the upper frame 26 on the outdoor side. The male threaded portion 23 at one end of the column 7 is inserted into a through hole in the column inner formwork or the beam inner formwork 37 .

A female threaded portion at one end of a tightening connector main body 38 is screwed into each of the male threaded portions 23 and 33, respectively, and a tightening tool 39 consisting of a nut is screwed onto the other end of each tightening connector main body 38. , the column inner formwork or the beam inner formwork 37 and the outer formwork 34 are tightened via washers 40 and vertical and horizontal flaps 41 and 42.

In the above embodiment, the metal plate formwork receiving piece 25
and a separator 7 having a truncated conical formwork receiving piece 8 with a connecting screw shaft, a tightening connector main body 38 screwed onto one end of the separator 7 and the connecting screw shaft, and a tightening connector main body 38. 38 is used, the formwork clamping connector 6 is composed of a fastener 39 consisting of a nut screwed onto the washer 40, but the formwork receiving pieces 8, 25 and the clamping connector main body 38 are used.
Also, other shapes or configurations of fasteners 39 may be used. Also, the intermediate support fitting 13
When manufacturing, support plate 10 and formwork mounting plate 1
A separate rib may be fixed to the support plate and the formwork mounting plate by welding.

FIG. 6 shows a leading sash frame support device that supports the upper frame and side frames that are not adjacent to columns and beams in the leading sash frame, and shows the inner formwork 30 and outer formwork 34 of the wall part. Since the length of the separator 7 in the formwork clamping connector 43, which connects the sash frames by tightening them at regular intervals, is short, the intermediate support bracket 13 is omitted, and the receiving bracket 4 in the sash frame support bracket 5 is used for the formwork clamping connection. Formwork receiving pieces 8, 25 on both sides of the fixture 43
However, the other structure is the same as that of the previous embodiment.

FIG. 7 shows a leading sash frame support device for supporting the lower frame of a leading sash frame, in which the locking piece at one end of the plate 1 of the sash anchor 1 is omitted, and the plate 14 is omitted. One end is fitted into a locking groove 45 on the outdoor side of the back side of the lower frame 44 in the tipped sash frame, and an outer auxiliary frame 46 inclined to the outer form frame 34 is fixed with a nail or the like via a wooden frame 47. However, the other configurations are the same as those in FIG. 6 and the previous embodiment.

When supporting four circumferences of one leading sash frame, the leading sash frame supporting device shown in FIGS. 4 and 5, the leading sash frame supporting device shown in FIG. 6, and the leading sash frame supporting device shown in FIG. It may be used in combination with a sash frame support device.

FIG. 8 shows another example of the sash frame support fitting 5, in which the support bundle 2 and the receiving fitting 4 are integrally and continuously constructed of one steel plate, and the receiving fitting 4
U-shaped portions 48 are cut and bent at both ends, and separator insertion holes 3 are provided, and concrete flow holes 49 are provided near the joint between the support bundle 2 and the receiving metal fitting 4. , and other configurations are the same as those of the sash frame support fitting shown in FIGS. 1 and 2.

According to this invention, the sash anchor 1 in the sash frame support fitting 5 is engaged with the side frame or the upper frame 20 of the front sash frame, and the sash anchor 1 in the sash frame support fitting 5 is connected to the receiving metal 4 in the sash frame support fitting 5 for fastening the formwork. Ingredient 6
The separator 7 is inserted through the separator 7, and the receiving metal fitting 4 is inserted into the formwork receiving piece 8 of the formwork tightening connector 6.
The support plate 10 of the intermediate support fitting 13, which is engaged at one end and fixed to the column side formwork or the beam side formwork 29 with nails 28, is inserted into the intermediate part of the separator 7 and attached to the receiving metal fitting 4. Since it is engaged with the other end, using the formwork tightening connector 6 used to tighten and connect the column inner formwork or beam inner formwork 37 and the outer formwork 34 at regular intervals, The side frame on the column side or the upper frame 20 on the beam side of the leading sash frame can be easily supported in a predetermined position, and the structure is simpler with fewer parts than conventional leading sash frame support devices. At the same time, assembly work can be carried out quickly, and the sash frame support fitting 5 is connected to the formwork receiving piece 8 in the formwork tightening connector 6 and the intermediate support fitting 1.
3 so that it does not move in the wall thickness direction, and is also held by the separator 7 so that it does not move in the wall inward direction, so that the leading sash frame can be supported in a predetermined position with high precision. Furthermore, since the intermediate portion of the separator 7 is supported by the intermediate support fitting 13, even if a long separator 7 extending from the column inner formwork or the beam inner formwork 37 to the outer formwork 34 is used, the separator 7 will not bend. Effects such as being able to strongly support the side frame or the upper frame 20 in a predetermined position in a stable state are obtained.
