Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a method of constructing a housing unit, and particularly relates to a method of constructing a housing using a box-type unit consisting of wall panels and ceiling panels. .

``Conventional technology'' In single-family prefabricated houses, etc., planned prefabricated houses called ``freestyle'' have been supplied in place of uniform, standardized houses, and along with this, exterior and interior Various designs and other variations have been developed to suit various needs.

Although this type of planned housing allows for strong individuality of the housing, there are disadvantages in terms of construction time and cost due to the increased reliance on on-site construction and the increased number of parts. , its industrialization has been progressing for some time.

Conventionally, the construction methods for such houses were steel-framed, wooden-framed,
Concrete 1. Methods differ depending on the system, but in wood-based houses (J), as an alternative to the conventional wooden frame construction method, external walls, floors, ceilings, etc. are constructed with panel-like parts that also serve as the structure. These are then joined together on site to create walls, floors,
There are ways to configure the ceiling etc.

This method involves laying unitized floor panels on a concrete foundation constructed on site, assembling the wall panels on the first and second floors, and then assembling frames, timber, etc., and then building the roof panels. This is a method of constructing a building by assembling the panels, and each panel is integrated with glue and screw nails, etc., and the floor panel is assembled using architraves on top of the adjusted mortar adjusted to the top surface of the foundation. At the same time, the first floor wall panel (J) is integrated with the foundation by inserting holes at the bottom of the wall panel into anchor bolts protruding from the top of the concrete foundation and tightening the bolts.

Incidentally, in recent years, even in the construction of such wooden houses, attempts have been made to assemble so-called floor panels, wall panels, etc. in a box shape and to joint the box units with each other.

Figures 11 to 13 show an example of the structure of a unit building using conventional box units (see Japanese Patent Application No. 142,260/1988 [-Unit Building Using Two-Wall Construction Method]).

That is, this unit building consists of a 17-shaped wall-shaped room unit L-A made up of wall panels 2 a and 2 b erected on two intersecting side edges of a floor panel I as a basic unit,
A U-shaped wall-shaped room unit group is formed by joining two 5-shaped wall-shaped room units l-A, and the two room unit groups formed as described above are placed on both sides, It forms a room section surrounded by wall panels 2a and 2b.

Then, as shown in FIG. 12, a roof unit 3 made up of an integrated roof panel 3a and a roof frame 3b is placed on top of this room unit, and they are interconnected and integrated.
It is designed to consist of a one-story house.

"Problems to be Solved by the Invention" The present invention aims to solve the following problems in the prior art described above.

That is, in the above-mentioned unit building, by connecting the 5-shaped wall-shaped rooms UNISO L-A to each other, it is possible to form a relatively wide room section with no pillars or walls in the center.
The basic structure of the unit is composed of a floor panel 1 and wall panels 2 a and 2 b erected on its side edges. Scaffolding must be prepared to erect 3, and if it is a two-story building,
Because the ceiling panels had to be erected on scaffolding,
The problem is that the workability is poor.

The present invention was proposed in view of the above-mentioned circumstances, and its purpose is to facilitate the construction of ceiling panels, etc. on the second floor and beyond, without the need for special scaffolding, etc. Another object of the present invention is to provide a method of constructing a unit house that can improve work safety and work efficiency.

"Means for Solving the Problems" In order to achieve the above object, the present invention includes a plurality of wall panels erected so as to form an indoor space inside, and a wall panel constructed on the upper end surface of the wall panels. This is a method of constructing a house using a box-shaped room unit constituted by a ceiling panel, in which the floor panel is laid on a concrete foundation, and then the room unit is installed apart,
Build a first-floor house by using ceiling panels and wall panels between these room units, and then assemble the room units apart from each other on top of the ceiling panels of this first-floor house.
A two-story house is constructed by connecting these room units with ceiling panels and wall panels, and a roof is further constructed on top of this.

"Function" In the method of constructing a unit house according to the present invention, a so-called unit house is constructed of a wall panel erected to form an indoor space inside and a ceiling panel installed between the upper end surfaces of the wall panel. Since we use a process of constructing a house using a single room unit, work such as installing ceiling panels and constructing roof panels can be done by standing on top of the ceiling panel of the room unit. This eliminates the need for scaffolding or the like for construction of ceilings, roofs, etc.
