きる。2. Description of the Related Art In recent years, it has been proposed to create a neat space in a dwelling unit without a beam shape in an apartment house (see Nikkei Shimbun, April 20, 1994, evening edition). For this purpose, a method is conceivable in which the floor surface in the dwelling unit is constructed by a single slab composed of an unbonded slab or a hollow slab. The unbond slab is PC
The floor can be made thinner using steel wires, and the hollow slab can be made lighter while maintaining strength.

重床とする必要がある。[0003] However, if the floor is made of a single flat slab, the floor will not be flat in the finished state by arranging equipment piping and the like, and arranging a washroom, a corridor, and the like. For this reason, in order to flatten the floor upper surface in the finished state, it is necessary to take a step in the skeleton and to arrange necessary equipment such as equipment piping in a portion having a low step to partially form a double floor.

プが来されてしまうという課題があった。However, in such a conventional floor construction method, when the floor surface is a double floor, inconveniences such as a decrease in the ceiling height occur, and the double floor is used. The complexity raises costs. For this reason, in the present situation, it is necessary to insert a small girder when taking steps on the frame, so it is not possible to convert the floor surface to PC (precast concrete) or unbonded slab, and the construction period is prolonged In addition, there has been a problem that the cost is greatly increased.
【０００５】そこで、本発明はかかる従来の課題に鑑み

削減を可能とする床の施工法を提供することを目的とす
る。[0005] In view of the above-mentioned problems, the present invention has an object to provide a floor construction method which enables the floor surface to be made into a PC, thereby shortening the construction period and reducing the construction cost.

At the same time, after laying a PC plate on a general portion where a step is not required, a general slab having the same height as the small beam portion of the stepped slab is arranged on the upper surface of the PC plate.

After arranging the required equipment in this manner, the upper surface of the recessed portion is moved to the small beam portion. Thus, the floor upper surface including the general slab disposed on the upper surface of the PC plate in the finished state can be entirely flattened. Even when the concave portion is formed, small beams are arranged on both sides of the concave portion, so that the strength of the stepped slab can be set high.

A pair of girders 14, 14 are installed facing each other between the longitudinal directions of the pillars 12 arranged at the four corners of each room 10 of the apartment house, and first, four thin-walled thin beams are provided between these facing girders 14, 14. The PC plate 16 is bridged over, concrete 18 is cast on the upper side of the PC plate 16 by casting, and a stepped slab 20 and a general slab 22 are constructed. In this embodiment, the PC plate 16 is divided into four pieces for transportation.

At this time, the concrete 18 is cast at a height flush with the upper surface of the small beam portion 20b of the stepped slab 20. The general slab 22 is formed as a hollow slab by forming a hollow portion by the void member 26.

Can be made flat throughout in the final finishing stage. It should be noted that the stepped slab 20 has the small beam portions 20b, 20b on both sides of the concave portion 20a even when the concave portion 20a is formed.
By forming b, the strength of the stepped slab 20 can be set high.

になる。Accordingly, in the floor construction method of the present embodiment, the stepped slab 20 having the recessed portion 20a is used. By finishing the upper surface of the portion 20a flat with the small beam portion 20b, the floor upper surface including the general slab 22 can be entirely flattened in a finished state. For this reason, it becomes possible to provide a flat ceiling and a flat floor, which have conventionally been conflicting requirements. Also,
Thus, the PC plate 16 can be used even though the floor surface can be flattened at the finishing stage, so that the construction period can be significantly shortened and the construction cost can be reduced.

Further, in this embodiment, after the truss bars 30 are arranged on the bottom surface of the concave portion 20a and the upper surface of the PC plate 16,
Cast-in-place concrete 18 is to be cast. The concrete 18 to be cast in the recessed portion 20a is shallowly cast, leaving a space for disposing the equipment pipe 24 in an upper portion.

るという各種優れた効果を奏する。As described above, according to the floor construction method of the present invention, a slab having a step is arranged at a portion where a step is to be provided, and a P slab is provided at a general portion where a step is not required.
Since the C version was laid and the general slab was arranged,
After arranging the required equipment in the recessed part of the stepped slab, the upper surface of the recessed part is finished so as to be flat with the small beam part. The surface can be finished flat as a whole. Therefore, it is possible to provide a flat ceiling and a flat floor, which have conventionally been conflicting requirements. In addition, even though the floor surface can be flattened at the finishing stage, it is possible to use the PC version,
Various excellent effects can be achieved in that the construction period can be significantly shortened and the construction cost can be reduced.
