Detailed Description of the Invention

TECHNICAL FIELD The present invention relates to a method for constructing an entrance unit in a unit house, and more particularly to a method for constructing using an entrance unit assembled with a sash with an entrance door. "Prior art" For detached prefabricated houses, for example, planned prefabricated houses called "freestyle" are supplied in place of the already standardized houses, and along with that, exterior and interior design Etc., various variations have been developed to meet various needs. While such planned houses can be strongly individualized, there is a drawback in that they are disadvantageous in terms of construction period and cost, etc. due to increased reliance on site construction and increased types of parts. Conventionally, the industrialization thereof has been promoted. Conventionally, the construction method of such a house differs depending on the steel frame type, the wooden type, the concrete type, but in the wooden type house, it is a panel shape that doubles as a structure as an alternative to the conventional wooden frame construction method. Outer walls, floors, ceilings, etc. are made up of parts, and these are connected to each other at the site to create walls, floors,
There is a method of constructing a ceiling or the like. In this method, a unitized floor panel is laid on a concrete foundation constructed on site, and the first floor and 2
This is a method to build a building by assembling floor panels such as floor panels, shafts and timbers, and assembling roof panels. Each panel is integrated with, for example, adhesive and screw nails. Also, the floor panel is laid on the adjustment mortar adjusted on the upper surface of the foundation through a pedestal, and the wall panel on the first floor is attached to the anchor bolt protruding from the upper surface of the concrete foundation at the lower end of the wall panel. It is designed to be integrated with the foundation by dropping holes and tightening bolts. By the way, in recent years, even in the construction of such a wooden house, a means has been tried in which so-called floor panels, wall panels, etc. are assembled in a box type and the box units are jointed to each other. When constructing a house with various box-type units, it is necessary to give due consideration to the transportation of the units. "Problems to be solved by the invention" However, in a normal unit, a box type unit can be formed by a method of assembling a wall panel on a floor panel, so that the lower surface of the unit is a flat surface without steps. However, there are still some problems to be solved when uniting the entrance area. That is, since the lower end of the sash of the entrance door at the entrance is usually supported by the part of the entrance tap that is one step lower than the floor surface on the first floor, if you try to construct a unit with the entrance sash attached, Because the attached sash is assembled at a position one step lower than the wall panel that composes other partitions, the lower surface of the unit cannot be made a flat surface without steps, which makes it difficult to transport the entrance unit. It is an issue. The present invention has been proposed in view of the above-mentioned circumstances, and an object thereof is to improve the workability on site by easily transporting an entrance unit having a sash with an entrance door from the factory to the site. An object of the present invention is to provide a method of constructing an entrance unit in a unit house that can be made. [Means for Solving the Problem] In order to achieve such an object, the present invention is to provide a front door part of a house in a factory, a wall body that forms a partition between the left and right sides of the front door, and a front door installed between these wall bodies.
