In the present invention, since the gate truss can be moved in the girder direction by the rail and the chain block can be moved in the girder direction of the girder truss, the chain block can be moved in the girder direction and the girder direction. Therefore, it is possible to pull up the concrete wall after construction and to stand it up at any position. Also, other materials and the like can be pulled up by this chain block.

The gate truss is mounted on rails on both sides of the foundation, and the concrete floor and the concrete wall are all constructed on the foundation. Therefore, the ground required for construction work is the foundation with rails on both sides of the foundation. All you have to do is secure.
Therefore, no working space is required outside the concrete floor for the two opposite sides of the base on the side where it is not necessary to attach the rails, and therefore the space between adjacent buildings can be made very narrow.

Further, in the present invention, a concrete floor is constructed on the foundation, a concrete wall is constructed by utilizing the flatness of the concrete floor, and further, the flatness of the rolled concrete wall is utilized. Since other concrete walls can be sequentially constructed, it is possible to construct all the concrete floors and concrete walls required for the rod structure at the construction site.

According to this method, after the concrete walls on the first floor are joined together, a concrete floor on the second floor is formed on the concrete walls, so that the concrete wall on the second floor can be used by utilizing the flat surface of the concrete floor on the second floor. It can be created sequentially.

Therefore, the present invention can construct not only a single-layer concrete building but also a two- or more-layer concrete building.

In order to connect the concrete floor to the concrete wall and to each other, the dovetail grooves formed during the construction of the concrete floor and the respective concrete walls are matched with each other, and reinforcing bars are arranged inside the dovetail groove to make concrete. Since the joining method is used, it is not necessary to join and join the reinforcing bars or steel frames as in the conventional case, and the joining strength can be increased and the work can be simplified.

When constructing a concrete floor or a concrete wall, if all necessary pipes such as pipes through which electric wiring is inserted, water pipes or gas pipes are arranged and embedded in advance,

[0051]

As described above, according to the method for constructing a concrete house or the like of the present invention, the concrete floor constructed in a rollover state and the flatness of the upper surface of the concrete wall are used as they are for other concrete floors and concrete. Since it is possible to construct the walls in the overturned state one by one, it is possible to construct each concrete plate material entirely inside the building without using the temporary frame for walls in the conventional construction method. It is possible to construct a building according to the present invention even in a narrow site where there is no room to attach.

Further, it is applicable to a multi-layer concrete house by repeating the above-mentioned method and building it upstairs.

Further, regarding the work of standing up the constructed concrete wall, the hardened concrete wall can be standing up by using the gate truss movable in the girder direction and the chain block movable in the beam direction. It reduces the manual labor of workers or eliminates the need for the ground when using cranes.

Further, the dovetail-joining method adopted as the joining means for the respective concrete members is excellent in the integrity of the members to be joined and can realize a high-strength joint structure. Since concrete, which is a plastic body, is filled inside, it is possible to connect the concrete members to be joined with priority, even if there is a deviation in the matching state of the dovetail grooves.

Further, when the concrete floor or the concrete wall is constructed, all the necessary pipes such as pipes through which electric wiring is inserted, water pipes or gas pipes are embedded in advance. The time and effort for implementing the piping can be saved, and the piping in the floor or wall can be implemented collectively when the concrete floor and the concrete wall are constructed.
