Description of the Related Art As is well known, a thick solid foundation (also called a raft foundation or mat foundation) is used as a foundation for supporting heavy objects, for example, a boiler or a turbine installed in a thermal power plant. It is usually employed. In particular, as a basis of a vibration source device such as a generator, the weight of the foundation is required to be at least about twice as large as the operating weight of the device for vibration countermeasures. In some cases, it may be necessary to construct not only the foundation that directly supports the generator, but also the foundation of the entire building in which the generator is installed as a thick solid foundation as large as 2 to 3 m.

Precast concrete foundation beam members are assembled in a plane lattice, and one end of each foundation beam member is joined to each other via cast-in-place concrete, so it is lighter in weight than a conventional general solid foundation. While being rational, the workability is improved, and it can greatly contribute to reduction of construction cost and shortening of construction period. In addition, the connection of the foundation beam members is carried out via footing of the pile head by connecting the foundation beam main reinforcements provided at their ends or in the middle of the span, so that the foundation beam members are joined together. Can be surely integrated structurally. Furthermore, if the foundation beam member is formed by stacking and fastening a plurality of segments in multiple stages vertically, it is applicable even when the foundation beam member has a large cross section, and in the longitudinal direction of the foundation beam member. The introduction of prestress can reduce the member stress, and the weight of the base can be adjusted by filling a heavy object such as concrete inside the plane lattice.
