４を梁に連結するものである。(Prior Art) The structure of the embedded metal fittings in a conventional light-gauge aerated concrete panel (hereinafter referred to as "ALC panel") is described, for example, in Japanese Patent Application Laid-Open No. 5'7-127051. In an example, as shown in FIG. 13, the embedded metal fitting 1 is formed into a "U" shape, the four sides of this embedded metal fitting 1 are fixed to reinforcing bars 2 by welding, and a long nut 3 is attached to the center part. Weld the embedded metal fitting 1 to the reinforcing bar 2 in this state.
It is configured to be buried within the panel body 4 of the ALC panel. and bolts supported by the beam (not shown)
By tightening the long nuts 3 to the long nuts 3, the panel body 4 is connected to the beam.

本の補強筋２とを厳重に溶接せねばならず、その溶接作
業が面倒で製造性低下の原因になっていた。In this case, the load acting on the embedded fitting 1 from the beam side via the long nut 3 is distributed over the entire panel body 4 via the four reinforcing bars 1, so the load is applied to the vicinity of the embedded fitting 1. This has the advantage of preventing the panel/main body 4 from being locally damaged due to the load. However, in the above configuration, since the load from the embedded fitting 1 is received by the four reinforcing bars 2, the embedded fittings 1 and 4 are designed to withstand the load.
The reinforcing bar 2 of the book had to be carefully welded, and the welding work was troublesome and caused a decline in productivity.

た。In addition to such known examples, there is also a configuration shown in FIG. 14, for example. In this case, for example, four arms 6 are welded to a long nut 5 to form an embedded metal fitting 7, and a fitting groove 8 formed at the tip of each arm 6 is fitted into a reinforcing bar 2. The structure is such that it is embedded within the panel main body 4. In this case, the structure of the embedded metal fitting 7 is complicated and it takes time and effort to manufacture it. Moreover, for example, the position of the long nut 5 is different from the type of AL.
When manufacturing the C panel, it is necessary to prepare the embedded metal fittings 7 with the lengths and angles of the arms 6 changed accordingly, which takes time and effort, and this also causes a decrease in productivity.

There was still room for improvement in terms of manufacturability, such as the time it took to change the position of the fitting.

This flat plate part is embedded in the panel main body so as to be directed from the outer wall surface side over a plurality of the reinforcing bars, and is formed on this embedded fitting and fits into the reinforcing bars to embed the reinforcing bars. It comprises a fitting groove portion for positioning the metal fitting, and a connecting member provided on the embedded metal fitting for connecting the panel main body to a beam located on the inner wall side thereof.

置変更も簡単である。(Function) Focusing on the fact that the direction of the load acting on the embedded fitting is mainly directed toward the inner wall surface, the flat plate part of the embedded fitting is applied to the outer wall side across multiple reinforcing bars. Therefore, the load applied to the embedded metal fitting can be reliably supported by the reinforcing bar without welding the embedded metal fitting and the reinforcing bar tightly. The structure of the embedded metal fitting is simple, and the manufacturing of the embedded metal fitting is easy.Furthermore, the fitting groove of the embedded metal fitting is fitted to the reinforcing bar, and the embedded metal fitting can be attached to the reinforcing bar. Because it is for positioning,
By simply shifting the fitting position between the fitting groove and the reinforcing bar along the reinforcing bar, the position of the embedded metal fitting can be adjusted and the position of the embedded fitting can be easily changed.

For example, two are formed, and a semicircular fitting groove 18 (see FIG. 3) is formed laterally on one side of the deep part of the notch 17. In this case, each notch 17 is located corresponding to the reinforcing bar 13 extending in the vertical direction, and each notch 17 is located corresponding to the reinforcing bar 13 extending in the vertical direction.
It has a shape that widens toward the inner wall surface so that it can be easily inserted. In addition, the fitting groove 1 at the back of each notch 17
8 is formed in a semicircular shape with a diameter slightly larger than the diameter of the reinforcing bar 13, and the refitting grooves 18 are oriented in opposite directions. Then, connect both cut-out portions 17 to 2 on the outer wall side.
Insert into the reinforcing bar 13 from the outer wall side and refit the groove 18
By fitting both reinforcing bars 13, the embedded metal fitting 1
The flat plate part 16 of No. 5 is positioned across the two reinforcing bars 13 on the outer wall side so as to be facing from the outer wall side, and in this state, the fitting groove part 18 and the reinforcing bars 13 are lightly welded and temporarily fixed. There is. On the other hand, as shown in FIGS. 1 to 4, a long nut 1 serving as a connecting member is provided at the center of the flat plate portion 16 of the embedded fitting 15.

納した成形型内に、軽量気泡コンクリートのスラリーを
注入してパネル本体１２を成形するものである。Next, a procedure for manufacturing the ALC panel 10 having the above configuration will be explained. First, after assembling the reinforcing bars 13 and 14 in a grid pattern,
Both cut-out portions 17 of the embedded fitting 15 are pushed into the two reinforcing bars 13 on the outer wall side from the outer wall side, and both bottom fitting grooves 18 are fitted into both reinforcing bars 13, thereby removing the flat plate portion 16. The two reinforcing bars 13 on the wall side are positioned so as to face from the outer wall side. At this time, when changing the position of the embedded metal fitting 15, the embedded metal fitting 15 is shifted along the reinforcing bar 13, and the fitting position of the fitting groove 18 and the reinforcing bar 13 is changed along the reinforcing bar 13. The embedded fitting 15 can be positioned at a desired position by simply shifting the fitting. Therefore, changing the position of the embedded fitting 15 is extremely easy. After positioning the embedded metal fitting 15, the fitting groove 18 and the reinforcing bar 13 are lightly welded and temporarily fixed, and then the reinforcing bar 13, 14 and the embedded metal fitting 15 are placed in a mold containing a lightweight mold. The panel body 12 is formed by injecting aerated concrete slurry.

Make sure to inject slurry. In order to increase the bonding strength between the embedded metal fitting 15 and the lightweight cellular concrete, the surface of the embedded metal fitting 15 may be roughened in advance by, for example, knurling.
そして、成形後、パネル本体１２を梁１１に取付けるべ

の補強筋１３によって受は支えられる形態となる。After forming, in order to attach the panel body 12 to the beam 11, as shown in FIG. It acts in the direction of pulling it toward the wall. In this case, the flat plate portion 16 of the embedded fitting 15 is applied from the outer wall side across the two reinforcing bars 13 on the outer wall side, so the tightening load is applied through the flat plate portion 16. The receiver is supported by two reinforcing bars 13.

置調節の容品化によって、パネル本体１２の製造性を確
実に向上させることができる。Therefore, unlike the conventional case, the embedded metal fitting 15 and the reinforcing bar 13
Even if the two reinforcing bars 13 are not tightly welded, the clamping load will be reliably supported by the two reinforcing bars 13 and the load will be distributed over the entire panel body 12 via both reinforcing bars 13. Local breakage, cracking, etc. of the panel body 12 due to the load is prevented. In this way, in this embodiment, it is not necessary to carry out strict welding work as in the conventional case in order to receive the load by the reinforcing bars 13, so that the welding work can be simplified accordingly. Moreover, the embedded metal fitting 15 is one flat plate part 1.
6 and a plurality of fitting grooves 18, the structure of the embedded metal fitting 15 is simple, and the manufacturing of the embedded metal fitting 15 itself is also easy. Manufacturability of the panel body 12 can be reliably improved by facilitating the manufacture of the embedded metal fittings 15, simplifying the welding work, and simplifying the position adjustment of the embedded metal fittings 15 described above.

Reinforcement bars 13 on the outer wall side instead of reinforcing bars 13 on the inner wall side
Since the bridge is supported by the concrete thickness A (
(see FIG. 2), the supporting strength of the reinforcing bars 13 by the concrete can be increased, and the effect of preventing local damage and cracking of the panel body 12 can be further enhanced.

ようにしたものである。In the first embodiment, in order to prevent the embedded fittings 15 from shifting due to the slurry injection pressure during panel molding,
The reinforcing bar 13 and the fitting groove part 18 are lightly welded to temporarily fix them together. However, if the structure is configured as in the second embodiment of the present invention shown in FIG. 5, temporary fixing by welding is not necessary. That is, in this second embodiment, the binocular alignment groove 18
By setting the interval between the two reinforcing bars 13 to be slightly shorter than the original interval between the two reinforcing bars 13, the eye alignment groove portion 18 is aligned with both the reinforcing bars 1.
3, both reinforcing bars 13 bend inward and their elastic restoring force maintains the fitted state of the two, thereby temporarily fixing the embedded fitting 15 to the two reinforcing bars 13. This is what I did.

The binocular alignment grooves 18 of No. 5 are configured to face opposite sides, but as in the third embodiment of the present invention shown in FIGS. It may also be formed toward the nut 19 side). In this case, by setting the interval between the refitting grooves 24 to be slightly longer than the initial interval between both reinforcing bars 13, when the binocular fitting grooves 24 are fitted to both reinforcing bars 13, In addition, as shown in FIG. 6, both reinforcing bars 13 are bent outward and their elastic restoring force maintains their fitted state.

Two fitting grooves 18.24 are formed to connect the flat plate part 16 to two.
Although the receiver is configured to be supported by the reinforcing bar 13 of the book, the structure is not limited to this. For example, as in the fourth embodiment of the present invention shown in FIG. 8, the embedded fitting 25 may be formed into a long length. The flat plate portion 26 may be arranged so as to extend over three or more reinforcing bars 13 so that each of these reinforcing bars 13 receives a load.

る。[Effects of the Invention] As is clear from the above description, the present invention focuses on the fact that the direction of the load acting on the embedded fitting is mainly directed toward the inner wall surface, and the flat plate portion of the embedded fitting is reinforced with a plurality of reinforcements. Since it is applied from the outside wall side across the reinforcement, the load applied to the embedded fitting can be reliably supported by the reinforcing bar without welding the embedded fitting and the reinforcing bar tightly, and the welding Work can be simplified. Moreover, since the embedded metal fitting only needs to be provided with a flat plate portion and a fitting groove portion, the structure of the embedded metal fitting is simple and manufacturing of the embedded metal fitting is easy. Furthermore, since the embedded fitting is positioned by fitting the fitting groove of the embedded fitting into the reinforcing bar, the fitting position between the fitting groove and the reinforcing bar can be simply shifted along the reinforcing bar. The position of the embedded metal fittings can be adjusted and the position of the embedded metal fittings can be easily changed, and together with the above-mentioned circumstances, this has the excellent effect of improving the manufacturability of the panel body.
