本考案は、建築構築物等のコンクリートスラブ
成形用の仮型枠保持用の取付金具に関する。[Detailed Description of the Invention] The present invention relates to a mounting bracket for holding temporary formwork for forming concrete slabs of architectural structures and the like.
従来この種のコンクリートスラブを形成する場

の部分で切断し残部をコンクリート中に埋ころし
にすることにより錆などが生じて表面が汚れたり
錆による亀裂が生じていた。 Conventionally, when forming this type of concrete slab, the temporary formwork was supported by welding round mesh to the main girder and holding the formwork with threaded bolts, but when the formwork was removed, Since the net was cut from the main girder, the residue remained on the main girder, which had an undesirable appearance. In addition, mounting brackets have been developed that are suspended from the main girder, but because a part of the bracket is embedded in the poured concrete, cutting it at this part and burying the rest in the concrete will cause rust and other problems, and the surface will become rough. There were cracks due to dirt and rust.

る型枠取付金具を提供するものである。 The present invention was developed to solve the drawbacks of these conventional construction methods, and uses beak-shaped suspension fittings and long bolts to not only secure scaffolding for work but also to embed in concrete. To provide a formwork mounting metal fitting that can easily remove even a complicated suspension metal fitting with a single hit of a hammer.

Figure 1 shows a front view of the hanging fittings of the present invention installed, Figure 2 shows an enlarged perspective view of the same, and Figure 3 shows the formwork suspension fittings of the present invention. This is a detailed diagram of the metal fittings of the invention, and the fourth
The figure shows a top view of the washer.

いては特に限定はしない。 In the figure, reference numeral 1 denotes a rectangular piece of metal as a whole, the head of which is formed into an arc shape 2, with a notch provided in the front (left side in the figure) and a beak-shaped suspension part 3 at the top. A nut 6 for screwing the bolt is welded and fixed to the lower part of the molded body. A long bolt is screwed into the nut 6, and the top of the long bolt 5 is formed into a chevron shape so as to make point contact when tightening. Further, a washer 13 is screwed into the lower part of the bolt 5, and several steel pipes 9 are suspended from the washer 13 to form a scaffold for work. Therefore, in the figure, the washer has a type 3 shape and two steel pipes are passed through it, but this shape is not particularly limited.

業上の効果は大である。 The formwork mounting bracket 1 of the present invention has the above-mentioned configuration, and when concrete A is poured as shown in FIG. Since it can be easily removed by hitting point K at the lower end with a hammer, it is easy to assemble, remove, and disassemble, which has a great operational effect.
