We proposed that this be done using structural hardware. FIGS. 2A and 2B are side views and exploded perspective views of the cast molded body attached to the outer wall panel in this case. In the figure, the arm 1d of the vertical plate 1e of the embedded hardware 1
The protruding arms 1a and 1b are made to have reinforcing bars for anchors penetrated in advance so that the side surfaces are aligned with the outer surfaces, and the whole is set in a formwork using welding if necessary and hardened with concrete. Reference numeral 2 denotes an auxiliary piece that is T-shaped when viewed from the side, and has a vertical hole 2 on the vertical side 2a above.
a 1 , horizontally elongated hole 2a 2 on the lower side, and vertically elongated hole 2 on the upper side.
The embedded metal fitting 6 is fitted to a 1 and fixed by tightening from the opposite side using a washer 6a and a nut 6b.

接性もよくない。Problems to be solved by the invention However, among the cast iron embedded metal fittings of the PC board, this embedded metal fitting 6, which is a bolt that connects to the connecting metal fittings, is a PC board.
Since the plate is set in the cast iron embedded metal fittings before the concrete is poured into the plate, as shown in Fig. 2C, a round bar 7 to prevent the bolt from falling and a cast iron member 5', which is a steel frame, are provided to prevent the bolt from falling and stop the bolt from rotating. However, welding properties are poor and tend to weaken the strength of the base metal. FIG. 2C shows this situation, in which the head of the mounting bolt 6, which is an embedded fitting, is welded to the round bar 7 and the cast iron material 5', but the workability and weldability to the cast iron are not good either.
問題点を解決するための手段
このような点を考慮して本考案ではボルト頭部
を押える位置に落下防止プレート３を設けるため
に鋳鉄製材５に該プレートさし込み溝を設けると
ともにボルトまわりどめ形状の周壁を作つた溝を
設けるものである。Means for Solving the Problems Taking these points into consideration, the present invention provides a groove for inserting the plate into the cast iron material 5 in order to provide the fall prevention plate 3 at a position where the bolt head is pressed, and In this method, a groove is provided with a circumferential wall having a circular shape.
作 用
このようにすることにより、ボルト頭部の落下
防止と回転止めとも同時に行い、取付ボルトとの
溶接や機械加工の工程をはぶくことができる。Function By doing this, the bolt head is prevented from falling and rotation is simultaneously prevented, and the process of welding and machining with the mounting bolt can be eliminated.
実施例

６′を保持するためのプレート３のための溝８が
設けられ、又取付ボルト６の回転防止を行う角部
を有する回転防止壁をもつ溝４が設けられるので
ある。Embodiment FIG. 1A is a side sectional view of the main part of the device according to the present invention, and FIG. 1B is a front view of the rotation stopper groove. 5 in figure
is made of cast iron and is provided with a groove 8 for the plate 3 for holding the bolt head 6' on which the mounting bolt 6 is provided, and also has a rotation prevention wall having a corner part to prevent the rotation of the mounting bolt 6. 4 is provided.
従つて、鋳鉄材５にそつて防止プレート３を挿

ように入れられれば取付ボルトの頭部周辺は鋳鉄
材５の溝４の角部にはまり込み、回転上のすべり

られ落下防止に役立つものである。 Therefore, if the mounting bolt 6 is inserted so as to contact the prevention plate 3 after inserting the prevention plate 3 along the cast iron material 5, the periphery of the head of the mounting bolt will fit into the corner of the groove 4 of the cast iron material 5. This prevents rotational slippage and the head 6' is held down by the plate 3, which helps prevent it from falling.

めを行なわせることができる。Effects of the invention As described above, in this invention, installation is facilitated by providing a groove into which the plate is inserted into the cast iron material 5, and a groove with a corner wall that prevents the head of the mounting bolt from turning. It is possible to prevent the bolt from falling and prevent it from rotating.
