DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a building unit in which a building unit previously manufactured in a factory or the like is slid on a foundation of a construction site and arranged at a predetermined position.

[0002]

2. Description of the Related Art Conventionally, interior equipment and the like are provided inside,
2. Description of the Related Art A building unit in which a floor structure is formed in a box shape is manufactured in a factory or the like in advance, transported to a construction site, and installed on a foundation to form a building. This construction method is excellent in that the number of construction steps at the construction site can be reduced by transporting the building unit to the construction site after the facilities and interior work in the building have been completed to some extent. But,
In this method, the building unit has a considerable size and weight, and if the building unit has to be placed at the back of the site, the foundation will be an obstacle and the crane cannot enter the site. In doing so, a large hoist is required. The transport of building units by a large hoist requires a large space, and particularly on small lands, installation using a hoist may be difficult. In order to solve this problem, a method of sliding a building unit on a foundation via a roller without using a large-sized hoist has conventionally been proposed.

Conventionally, when arranging building units on parallel cloth foundations, rail members are linearly placed on both cloth foundations, and the building units are slid on the rail members via rollers. The building unit is lifted using a portal crane or the like at the predetermined position, the rail members are removed, and then the building unit is lowered again to fix the building unit on the cloth foundation. According to this method, there is no problem in the case where the building is straight from the entrance of the site in contact with the road to the location where the building unit is installed.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a method of constructing a building unit using a rail member which can cope with a case where the transport route from a site entrance contacting a road to a building unit installation location is not linear. That is.

[0005]

A building unit is mounted on a frame provided with rollers, and is slid on a cloth foundation for construction so that the running direction of the rollers can be freely changed in both vertical and horizontal directions. Thereby, the direction of the transport direction of the building unit can be changed, and even when the transport path is bent at a right angle, the building unit can be transported by sliding the rail shape.

In order to change the direction, the gantry is provided with rollers that roll in the vertical and horizontal directions, and one of the rollers in the vertical or horizontal direction is lowered and the other is raised. Thereby, the direction can be easily changed.

The hook at the tip of the metal rope wound on the winch is locked to the gantry 8, and the building unit 1 is slid up by the winch. Next, the building unit 1 is lifted by a small crane such as a portal crane, and in this state, the direction of the rollers 9 provided on the gantry 8 is changed.
That is, by replacing the spacer, one roller 9 is raised and the other roller 9 is lowered in the orthogonal direction. The building unit 1 is slid by the winch attached to the end of the rail in the traveling direction and transported to the installation position. Finally, the building unit 1 is lifted by a portal crane or the like, and the gantry 8 and the rails located under the building unit 1 are removed. 1 is lowered to fix the building unit 1 to the base hardware 4 and the bundle.

In this embodiment, the rollers 9 in the orthogonal direction are provided, and the direction is changed by moving them up and down. However, the rollers 9 themselves may be rotated or the direction may be changed by attaching and detaching the rollers 9. Good.
