Description

[Detailed Description of the Invention] The present invention relates to a support fitting for an outer formwork at a joint of a building frame when constructing a concrete structure.

Next, an example of the implementation of the supporting bracket of the present invention will be explained with reference to the drawings. In Figures 1 to 3, a long hole 2 is provided for vertically extending mounting at the mounting part 1 along the wall surface, and the mounting A formwork support part 3 is provided which projects horizontally at right angles to the upper end of the part 1, and a vertical adjustment bolt 4 is provided on the base end side of the formwork support part 3, and a formwork tightening device 5 is provided on the rear end side. However, in order to attach the mounting part 1, a through hole 2a having a diameter substantially larger than the inner width a of the long hole 2 is provided at one end or both ends of the long hole 2, and the mounting part 1 is installed vertically vertically. It is curved into a bow shape.

In addition, the formwork support part 3 fixes the base end and rear end of the upper and lower pieces 3a and 3b with the required spacing, and the upper and lower parts 3a on the base end side are partially recessed 3a' and rotated to the upper end of the vertical adjustment bolt 4. A freely provided saucer 4a can be stored therein, and a stopper 3b is integrally protruded upward from the rear end side.

Further, as an example of the formwork tightening device 5, wedge press-fit holes 5a are provided at predetermined intervals in the front and back of the upper and lower pieces 3a, 3b of the formwork support part 3.
, 5b are provided.

Furthermore, for mounting in the mounting part 1, it is possible to provide a convex part for reinforcement that bulges out rearward along the long hole 2, or to install a square bar with a large diameter at one end as shown in Fig. 5. In order to form a through hole 2a', a long hole 2' (groove) is installed in the vertical direction.
It is also easily conceivable to provide a.

As shown in Fig. 4, the support fitting of the present invention constructed as described above is installed by inserting the elongated hole 2 into the male threaded part of the separator S at the splicing point of the concrete body C, and positioning it at the required height. Then tighten the formwork tightening rod F or a regular nut from behind to firmly tighten the curved surface of the attachment part to the outside of the concrete frame.

Furthermore, after placing a suitable large tension material A on the vertical adjustment bolt 4 of the formwork support part 3 and adjusting it to a predetermined level,
A wedge K is press-fitted into the wedge press-fit hole 5a in the formwork tightening device 5, and the large tension material A is fixed.

The outer wall formwork P stands on the large lumber A, the lower end of the formwork crosspiece Pa is nailed to the lumber A, and the inner wall formwork P is set on the pouring surface and then Conch notes will be poured.

In addition, when using a bulging head separator S' for locking wedges (not shown) at both ends, the mounting of the support fitting is as shown in Figure 6. 2
A is inserted into the head of the separator S', and the above-mentioned wedge or wedge-type formwork clamp is press-fitted into the inside of the head of the separator at a predetermined position in the elongated hole 2, thereby tightening it to the outer surface of the concrete frame. be.

According to the following supporting metal fittings of the present invention, not only can the support of the outer formwork at the joint part and its level adjustment be done easily and freely, but also the attachment to the outer surface of the Conch IJ-1 frame is particularly easy. By curving it into an arched shape, it is possible to obtain strong tightening force due to the effective spring action, and the simple structure has the effect of ensuring accurate installation and formwork support.
