[0002]

2. Description of the Related Art In the present construction method of building frame, for example, 10
In the case of a one-story building, first the underground foundation is constructed. After the underground construction, concrete on the first floor is poured. And after that, pillars, walls, girders on the first floor,
The beam and the floor are assembled by the formworker and the reinforcing bar, and concrete is placed on the entire first floor from the pillar on the first floor to the floor on the second floor. After the construction of the first floor is completed in this way, the construction of the second floor is started. The construction of the 2nd floor is the same as the construction of the 1st floor, and 3
The first floor will be done after the construction of the second floor is completed.
As described above, the current building skeleton construction method employs a method of sequentially starting each floor such that after the concrete pouring of one floor is completed, the construction of the next floor is started. In addition, the formworker puts a training period for the placed concrete, then dismantles the formwork, and conveys this formwork to the next floor for use.

In the construction method as described above, most of the construction work is carried out on-site and a period for training the placed concrete is required. Therefore, the movement of the formwork influences the construction period. . Also, since most of the construction work is site work, people of each occupation such as formwork, rebar work, steel work, equipment work, etc. are congested, so the construction schedule and conditions will greatly affect the construction period. .

Therefore, in the present invention, the members of the complicated parts of the site work are made into PC in advance (precast concrete).
By doing so, it is intended to save labor on site and to shorten the construction period on site by advancing the frame work for columns, beams, and floors. Another object of the present invention is to provide a building skeleton construction method that does not require a skilled formwork by converting a member of a complicated part of the site work into PC (precast concrete) in advance.
