Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of installing housing units assembled into a prefabricated house, and a frame and a slope base used in the method.

(Conventional technology) An assembled house is a box-shaped housing unit of a certain size that can be transported, and the interior and exterior have been finished.The units are manufactured in advance at a factory, and multiple units are transported to the construction site. , which can be assembled on-site and turned into a house.

This type of prefabricated housing has been increasingly adopted in recent years because it has the characteristics of a short construction period and standardized housing with good dimensional accuracy.

However, the housing unit 1- is usually completed by lifting the housing unit with a tow truck, installing and assembling it, and then finishing it, but in the case of a private residence, it is installed in a place large enough for a large tow truck to operate. There aren't many.

Therefore, a small rafter type crane is usually used among tow trucks, but because this rougher type crane is small, depending on the site, the tow truck boom may not be able to reach the depths of the site, and residential units may not be able to reach the back of the site. It may not be possible to install it deep inside.

As a way to solve this problem, Japanese Patent Publication No. 11'288
A method described in Publication No. 9 has been proposed.

In this method, the housing unit is pre-assembled on the foundation within the reach of the tow boom of the rafter crane, and after the exterior work has been completed, the housing unit is moved on the foundation and installed in its final position. be.

(Problem to be Solved by the Invention) However, in the method described in Japanese Patent Publication No. 1-12889, after a housing unit is assembled at a position different from the final position, the assembled building is moved to the final position. However, since housing units are heavy, this movement is extremely difficult.

Moreover, during this movement, the assembled building often vibrates, causing problems such as dimensional deviations and damage.
