The illustrated gantry 6 includes a lower gantry 16 and an upper gantry 26 mounted on the gantry 16. The lower gantry 16 includes a rectangular frame 17 and receiving members 18, 18 and 4 for supporting the upper gantry 26.
The upper pedestal 26 comprises the lower pedestal 16
The upper and lower frames 27, 27, which are smaller than the frame 17, and four vertical members 28 are formed in a box shape. Thereby, stability is good at the time of building the pillar structural member A having a large weight. At least the upper frame 27 of the upper and lower frames 27
Is temporarily fixed with a holding member 29 for temporarily holding the column member A, and the holding member 29 is used as a guide for the member A.

It can also serve as protection. The same frame B is a cylindrical body, the inner diameter of which is equal to or greater than the diameter of one pile, the foundation rebar basket 9 is arranged in the space where the soil in the same frame B is excavated, and the column member A is constructed. When the concrete 7 of the foundation 8 is placed and the concrete 7 is cast, the integration of the pillar component member A and the pile 1 is significantly strengthened by the foundation 8. Thereby, the degree of fixation of the connecting portion between the pillar component member A and the pile 1 is increased, so that the swing against an external force such as an earthquake can be reduced. When the scale of the upper frame is small, it is only necessary to omit the foundation reinforced cage 9 and to place the concrete 7 of the foundation 8 in the formwork B.

The following effects can be obtained. (1) The case is buried in the ground to excavate a pile hole, and concrete is cast in the pile hole. By integrally constructing the components, <a> it is possible to construct the ground frame at an early stage, thereby shortening the construction period and reducing the construction cost. <B> Since the process from the construction of the piles to the construction of the pillar components on the ground is consistent and continuous, the work efficiency is improved. <C> Since the pillar components are built using the gantry as a guide, the construction accuracy is improved. <D> Since the connection between the pile and the column member is surely integrated, the proof stress increases. (2) Embed a foundation construction formwork in the ground, excavate this foundation construction formwork and excavate a pile hole below it, and place concrete in the foundation construction formwork and pilehole. After casting
In addition to the above (1) <a> to <c>, the above-mentioned (1) is constructed by installing the pillar component members of the ground part in the foundation construction formwork and the pile hole and integrally constructing the foundation and the pile and the pillar component members. <a> The formwork for foundation construction also serves to construct the foundation and protect the hole walls of the pile holes, so that the working efficiency is good and economical. <B> When a steel formwork is used for the foundation-building formwork, the steel formwork can resist the shearing force when a large concentration force acts on the foundation. Can,
In addition, it is economical because the number of basic rebars can be reduced. <C> The connection between the pile, the foundation, and the pillar component is increased in the degree of fixation by integration, so that the proof stress increases. (3) By pre-attaching the basic reinforcing bar to the lower part of the pillar component, <a> the development of consistent continuous construction is further expanded, and the work efficiency is greatly improved. <B> Since the strength of the foundation further increases, it is more excellent in earthquake resistance.
