【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、RC造等の複合化工法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a compounding method such as RC construction.
［従来の技術］ 一般に、RC造に於いては現場での型枠の組立て及び配

また、従来のRC工法によると、スラブの施工後でないと
型枠を解体し転用出来ないため、型枠の転用サイクルが
長くなり極めて非能率的であった。[Conventional technology] In general, in RC construction, it is troublesome to assemble and arrange the formwork on site, dismantle and move the formwork after placing concrete, and lack formwork carpenters and arrangers. This leads to a decrease in work efficiency, which in turn leads to a longer construction period.
In addition, according to the conventional RC method, the formwork cannot be dismantled and converted unless the slab has been constructed, so the cycle of reusing the formwork becomes long, which is extremely inefficient.

合化工法を提供することを課題としたものである。[Problems to be Solved by the Invention] The present invention has been made to solve the conventional problems as described above, and in particular, in the RC construction, the slab is not installed by the introduction of the PC floorboard, and the column and beam molds are not formed. It is an object of the present invention to provide a composite construction method such as RC construction which employs a large formwork capable of disassembling and converting a frame, thereby significantly improving construction efficiency, reducing the number of workers and shortening the construction period. .

工が不要になる。The construction sequence according to the present invention can be roughly divided into five steps from FIG. 1 to FIG. 5, that is, the first step shown in FIG.
The process is a process of assembling the column 1, the beam 2, and the wall 3, and inserting the sleeve 4 into a key point of the beam 2 after the lower floor is formed. In the next second step, as shown in FIG. 2, the large formwork 5 is installed so as to sandwich the wall reinforcement 3 and the column reinforcement 1, and as shown in FIG. After the mounting, concrete is cast into the large formwork 5 to form walls and columns. The large formwork 5 can employ a large formwork such as a shuttering system or a biosystem, weighing about half as compared with a steel formwork, and a scaffold is set on a panel surface. Can be handled sufficiently, eliminating the need for on-site formwork.

る。After curing of the cast concrete, a third step is performed. This is a step in which the large formwork 5 is removed and the floorboard 7 is laid and the balcony 8 is installed as shown in FIG. . The floor plate 7 is, for example, a type of precast concrete (PC). A span cleat having a plurality of hollow holes penetrated in the length direction of the plate can be laid between beams without support. Suitable flooring can be used. On the other hand, as the balcony 8, a so-called half PC board can be used. The fourth step is, as shown in FIG. 4, a step of arranging the mesh reinforcing bars 9 on the floor formed by laying the floor plate 7. At this time, although not shown, it is preferable to provide necessary piping and wiring using the sleeve 4. Thereafter, in a fifth step, concrete is cast on the mesh reinforcing bars 9 to form a slab 10 as shown in FIG. To form beams and balconies. In this way, the construction process of one floor is completed, and the upper floors are sequentially formed by repeating this process cycle.

Instead of performing the entire floor in the order of the steps,
As shown in the figure, one floor covers 6 sections from the 1st section to the 6th section.
Divided into two sections, and a separate process worker team is formed from the first step to the fifth step, and this worker team moves in each section (P direction shown in FIG. 6), so to speak. Are completed in order. That is, the sixth
The worker team in charge of the fifth process, who completed the concrete placement of the slab in the construction section, moved to the fifth construction section, cast concrete on the floor where the mesh was already laid, and was in charge of the fifth construction section before that. The fourth process worker team moves to the fourth section and performs the reinforcing work on the mesh reinforcing bars. Such a construction method is wide in a plane,
It is suitable for RC buildings such as apartment houses, schools, hospitals, etc., which have a certain number of floors and are divided into several work sections on a plane, and these work sections have relatively uniform spans and wall positions. is there. Further, even in the case of SRC, it is possible to apply the case where the above conditions are satisfied and the laminating method is to incorporate a steel frame into one floor process.
