Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carriage with a turntable for conveying a building member when constructing a building and a conveying method. To explain in more detail, in the construction method in which the top floor of the building is constructed first and the lower floor of the top floor is constructed while sequentially raising the top floor upwards, the building material is grounded along with the rise of the top floor. Of the horizontal transfer device and the vertical transfer device are used to transfer the product to a predetermined working floor and supply building members to the same floor.

[0002]

2. Description of the Related Art In the construction method described above, for example, a temporary pillar is erected on a frame of a lower floor of a building to be constructed, and a pillar, a beam, and a roof, which are the uppermost floor of the building, are provided above the temporary pillar. The constructed roof structure and the roof structure are lifted by a lift-up device that raises the temporary pillars by using the lower floor as a reaction force to create a one-level space in the roof structure and to construct a building material in the same space. In the construction method to be supplied and assembled, a ceiling traveling rail is installed in the frame frame under the roof structure and a trolley hoist for vertical and horizontal transportation is installed, and the trolley hoist hoists vertically from the above-ground portion and runs on the assembly floor.
