型（木型枠＋支保工）が依然として多い。2. Description of the Related Art When designing a floor frame structure of a building in which seismic resistant elements are arranged around the outer circumference, only the vertical stress is targeted. Therefore, conventionally, a flat slab structure or a rigid frame structure with a relatively small cross section is used. Economically designed. In terms of construction method, the rationalized construction method is rarely adopted, and there are still many conventional types (wooden formwork + support work).
【０００３】[0003]
【発明が解決しようとする課題】しかしながら、将来の
建設業を取り巻く環境（木型枠の減少、建設労働者の減
少等）を考えた場合、木型枠・支保工を用いない、より
一層の合理化工法が望まれている。However, considering the environment surrounding the future construction industry (decrease in wooden formwork, decrease in construction workers, etc.) A rationalized construction method is desired.

構では、一方向板になって床荷重が一方向の大梁に集中
作用し、また床板が大型化するなどプレキャスト化が容
易でない。また、床荷重を二方向の大梁に分散伝達させ
るべく格子梁を使用すると、施工が面倒となる。Therefore, a construction method has been considered in which the columns, beams, and floorboards are composed of divided precast members to reduce the use of wooden formwork and to eliminate unsupported construction. Then, it becomes a unidirectional plate, and the floor load concentrates on the unidirectional girder, and the floorboard becomes large, so it is not easy to precast. In addition, if grid beams are used to disperse and transfer the floor load to the large beams in two directions, the construction will be troublesome.

となる床架構を提供することにある。The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a floor load to a large beam in two directions with a relatively simple structure in a building in which seismic resistant elements are arranged around the outer circumference. An object of the present invention is to provide a floor frame structure that can be distributed and transmitted and can be easily precast.

Instead, it may be cast on site.)
In the above, a girder is bridged between the capitals of the four pillars that surround one pillar as the center, and a girder is bridged between the capital of the pillar of the center and the middle part of the four girders. A floorboard is arranged in a small section composed of and supported by a large beam and a small beam.
