【考案の詳細な説明】
本考案は、主として集合住宅等、同スパンの平面が連続
するようなＳＲＣ構造の建築物を対象とするオムニア版
と併用したプレキャストコンクリートの小梁と現場施工
される大梁との接合部構造に関するものである。[Detailed explanation of the invention] This invention is mainly aimed at buildings with SRC structure where the same span is continuous, such as apartment complexes. This relates to the structure of the joint with.
一般に、上述建築物のスラブａおよび小梁すは、第１図

。Generally, as illustrated in Figure 1, slab a and small beams of the above-mentioned building are often constructed with cast-in-place concrete after formwork is constructed together with large beam C. Therefore, the reinforcing bars of slab a and small beams All of the reinforcement work and form beam work are done on-site, and both the upper end main reinforcements d and the lower end main reinforcements e of the small beams in this case are through reinforcing bars.
また、スラブにオムニア版を採用する例も多くあるが、
はとんどの場合、現場打ちの小梁ないしは大梁に添置さ
せているものである。In addition, there are many examples of adopting the omni version for slabs,
In most cases, they are attached to cast-in-place beams or girders.
さらに、小梁に第２図が示す如くプレキャストコンクリ

クターの開発がなされておらず、現場打ちコンクリート
スラブとの一体化に問題があった。Furthermore, as shown in Figure 2, precast concrete f may be used for the small beam, but in this case, the joint g with the main beam C requires metal girder or welding, so it is constructed using cast-in-place concrete as described above. As with small beams, not only do they have many difficulties in terms of workability, precision, and cost, but conventional precast concrete beams have not developed suitable shear connectors, making it difficult to integrate them with cast-in-place concrete slabs. There was a problem.
そこで、本考案は上述従来の事情に鑑みて検討の結果な
されたものであって、プレキャストコンクリート小梁（
以下ＰＣ小梁と称す）と、スラブと共に現場打ちコンク

In FIGS. 3 and 4, the PC beam 1 has an RC structure, and the upper end of the stirrup 2 is protruded from its upper surface, and a large diameter reinforcement is arranged inside. lower end reinforcement 3
is the end of the PC beam, that is, the connection part 1a with the main beam 4
""C" A protrusion is provided on the U-shaped reinforcing bar 3a, and further,
The above-mentioned connecting part 1a is provided with a cutout part 1b as a shark stopper, and an inclined reinforcing bar 5 for temporary support is embedded in the PC beam, and the other end is formed to protrude upwardly in an inclined manner. ing.

。In this way, the PC beam 1 is temporarily supported on the formwork 6 of the girder 4,
After that, an omni version 7 which is also used as a formwork for the slab is placed on the PC beam 1, and the upper end reinforcement 8 of the beam and slab is...
After arranging reinforcement, the slab 9 and the upper part of the small beam 1 are integrally constructed with cast-in-place concrete along with the girder 4.
