返し使用する。 To explain the general step pouring method, as shown in Figure 1, the concrete is buried in the upper end of the existing concrete part of a concrete formwork that has the total height of the existing concrete part and the height of the next concrete part. The free end side of the fixed anchor is fixed to the formwork, and at the bottom end of the formwork, with the anchor as a fulcrum, the upper end side of the formwork is tilted toward the space side of the next concrete part to be poured. , by attaching a strut material that slightly separates the lower end of the formwork from the surface of the existing concrete section, and by the cooperation of both anchors and strut materials, it counteracts the lateral pressure of the concrete section to be poured next; After pouring, the formwork is removed and used repeatedly for the next process.

て経済的負担増を招く欠点があつた。 As shown in Fig. 10, the round timber reinforcement formwork used in such tiered construction method consists of two groove-shaped members 02 as round timbers placed side by side with a certain distance between them. It was constructed by connecting the long side portions of the member 02 with two flat plates and integrally fixing them to the formwork 01. This product was specially designed for use in the step construction method, and was disadvantageous in terms of production cost.It also had the drawback of not being able to be used for other purposes, resulting in an increased economic burden for the contractor.
本考案は、かかる実情に鑑み、端太材として汎

挿通孔を設けてある点にある。 The characteristic structure of the fitting for assembling concrete formwork and thick timber according to the present invention, which was made to achieve the above object, is that the two square thick timbers are pressed into contact with the back side of the concrete formwork. Each has two fitting parts that can be fitted in a parallel position to each other to form an appropriate gap over their entire length, and each fitting part has a tightening connection on the outside. It has a flange portion, and an insertion hole for a fixing connector to the concrete formwork is provided at a central position between the two fitting portions.

るとともに、施工業者における経済負担の低減化
に寄与する効果大である。 In other words, the flanges of a pair of fittings in which square end pieces are fitted and held from the front and back sides at the fitting portions are tightened and connected to each other, and the flange portions are connected to the concrete formwork via a fixed connector, By assembling it in pressure contact with the back of the concrete formwork, it is possible to assemble the required thick reinforcement formwork, so there is no need to use a specialized formwork as in the past, and it can be used for general purposes. The square end lumber and formwork can be used as is, which is advantageous in terms of production costs and has a great effect in contributing to reducing the economic burden on the contractor.
更に、第9図に示すように、端太材の多段使用
も可能であり、コンクリートの側圧に対する適用
範囲を広げることができる点も効果の一つであ
る。 Furthermore, as shown in FIG. 9, it is possible to use multi-stage thick timbers, and one of the advantages is that the range of application to the lateral pressure of concrete can be expanded.
以下、本考案構成の実施例を図面に基いて説明
