に押当てている。[Detailed explanation of the invention] Conventionally, tightening of the outer corners of concrete formwork was done by
The vertical flaps are arranged on the outside of the intersection of the horizontal flaps on both sides that protrude at the corners of the formwork, and a chain with a turnbuckle is connected to the formwork tightening device on both sides of the corner and the vertical flaps. etc. (hereinafter simply referred to as chains) are attached at both ends, and the vertical beams are pulled by the chain and pressed against the intersections of the horizontal beams on both sides.

の隅のところが張出してくる。 Therefore, while concrete is being poured into the space surrounded by the weir plates of the formwork, the lateral pressure of the concrete is applied to the lower part of the formwork containing concrete, and the upper part of the formwork that is not filled with concrete is subjected to lateral pressure. The above chain loosens because the concrete lateral pressure is not applied and the horizontal beams on top of it descend.
The weir plates on both sides of the corner are opened, and the corner of the concrete wall is exposed.

点があつた。 Therefore, workers have to adjust the tension of the chain until the concrete is poured, which is time-consuming, and it is difficult to form the corners of concrete walls accurately, and It is dangerous if it becomes misaligned. Furthermore, the chain must be attached and detached each time the formwork is constructed, and if the chain is removed when the formwork is dismantled, the chain becomes bulky and there is no place to temporarily store it, so the chain must be attached to a scaffolding board. It is extremely dangerous to temporarily store it on top of the floor. On top of that,
Chains have drawbacks such as poor workability because they are heavy and bulky.

型枠隅部の締付金具に係るものである。 Therefore, in order to eliminate the above-mentioned defects, the present invention utilizes the intersecting protrusions of the horizontal beams on both sides of the corner of the concrete form, attaches a clamp with an internally threaded cylinder to each of the protrusions, and screws the female thread into the internally threaded cylinder. Using the end presser foot of the tightening bolt that has been passed through, press the vertical flap material to the outside of the intersection of the horizontal flap materials on both sides, and press it to the outside of the intersection of the horizontal flap materials on both sides, and then press the vertical flap material and the horizontal flap materials on both sides to the corner of the formwork on both sides. It is possible to securely hold and hold the weir plate to accurately form the corners of the concrete wall, and at the same time, it can be used until the end of construction without removing it from the horizontal beams, saving labor and making it easy to handle. This invention relates to a fastening fitting for the corner of a concrete form that improves work efficiency and is extremely beneficial in terms of safety.

できる。 In the present invention, since the clamping fittings for the corners of the concrete form are constructed as described above, the clamping fittings are attached to the intersecting protrusions of the side beams on both sides of the corner of the formwork, and their pressers are used. When the vertical beams are pressed into the outside of the intersection of the horizontal beams on both sides, the vertical beams securely attach the weir plates on both sides of the corner through the horizontal beams on both sides of the corner of the formwork. By holding the presser down, the weir plates on both sides of the corner of the formwork will not open during concrete pouring, allowing for accurate formation of the corner of the concrete wall.
