この発明は、新規な組立鉄筋補強半プレキャストコンク
リート版とその製造方法、それを用いたスラブ構法の提
供に係わる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel prefabricated reinforced semi-precast concrete slab, a method for manufacturing the same, and a slab construction method using the same.
最近、果合住宅あるいはスーνく−マーケット等で、長
スパンのスラブシステムの要求がでている。Recently, there has been a demand for long-span slab systems in residential buildings and souvenir markets.
この種のニーズに応え、型枠兼用の組立鉄筋補強の半プ
レキャストコンフリート版によるスツプ構法が既に開発
されているが、この際用いられるところの従来の組立鉄
筋補強半グレキャストコンクリート版では、長スパンを

構法を実現させるべくなされ友もので、以下、これの詳
細を図にもとづいて説明する。In response to this type of need, a stump construction method using semi-precast concrete slabs reinforced with prefabricated reinforcing bars that can also be used as formwork has already been developed. Constructing a span without support means that the bend is strong and the bend is rigid.
The present invention was made to realize the unsupported length span slab construction method in view of the actual situation on ridges, which was not possible due to the shortage.Hereinafter, the details of this will be explained based on the drawings.

、スパンス２プ構法を可能とした点にある。First of all, the gist of the assembled reinforcing bar reinforced cow precast concrete version of the present invention is as shown in Fig. 1. Although involved in
Since the degree is related to the cross-sectional area of the upper chord muscle, we focused on the fact that it cannot make much of a contribution, and as shown in FIG. 3, and its cross-sectional area is greatly increased, and there is no trap t1 for the lower jllllffi4 in the plate, the lower chord mzbt in the assembled reinforcing bar 2, and the concrete layer 5! The strength of the version of the song is that it made the span two-spring construction method possible.

第３図にグラフ示する。Assembly reinforcing reinforcing semi-grey cast concrete plate 6t of the present invention constructed like a ridge - 1st. Designed with the dimensions shown in Figure 2, the results of comparing the performance of the two are missing. In other words, assuming a Young's coefficient of t-756, the conventional version 2
For, stiffness I = 2208 (cm') tensile section modulus Z, = 669 (am') compression porcelain section modulus Z. = 211 (cm") Also, for version 4 of the present invention, I = 6767 (am') l t = 1514 (cm') Z c = 587 (am'), and the version of the present invention is Compared to the conventional model, the rigidity is approximately 3 times higher, the tension side section modulus is 2.25 times higher, and the section modulus of the hammer is 25 times higher, making it possible to temporarily construct unsupported structures even over long spans. It is possible, and the results of both bending experiments are shown graphically in FIG.
