Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a floor construction method for an industrialized house in which a plurality of housing units are combined and built on site, and can be used for a unit construction method.

[Background technology]

Recently, the number of industrialized houses constructed by the unit construction method is increasing in order to increase the industrialization rate and shorten the construction period on site. In this industrialized house, a housing unit manufactured in advance in a factory is transported to a site, and at the site, a plurality of housing units are assembled on a foundation and installed. In this house as well, as in houses other than industrialized houses, floors are constructed in the living room, dining room, etc. Generally, in the living room, dining room, etc., floor-like flooring is used for floor construction.

Conventionally, in order to construct a floor using a flooring in the industrialized house, a flooring having a convex portion at one end and a concave portion at the other end is used in a living room or the like in a state where the convex portion and the concave portion are fitted to each other. The multiple housing units that make up the are lined up from end to end.

[Problems to be Solved by the Invention]

However, in the above-mentioned conventional example, since the flooring is arranged at the site, a work time for this is required, and there is a problem that the construction period required at the industrial house cannot be shortened sufficiently.

It is an object of the present invention to provide a floor construction method for an industrialized house, which can shorten the construction period at the site, has high construction accuracy, and does not bend the joint material even when a person rides on it.

[Means and Actions for Solving the Problems]

The present invention is a method of constructing a floor on an adjoining housing unit of an industrialized house, which is constructed by combining a plurality of housing units on site, and a plurality of flat base materials are arranged in each housing unit in a factory. A plurality of floorings each having a convex portion at one end and a concave portion at the other end are arranged on the above, with the convex portion and the concave portion fitted together, and then, a flat plate-shaped base is provided between adjacent housing units at the site. By arranging the material, a joint material having a protrusion that engages with the upper surface of the convex portion of the flooring is arranged on the base material, thereby reducing the work at the site, and
It is an object of the present invention to achieve the above object by covering the projection of the flooring with the projection of the joint material so that the joint between the flooring and the joint material is inconspicuous.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 shows the layout of the first floor of an industrialized house constructed by the unit construction method. In FIG. 1, the first floor of the industrialized house is a living room 1, a dining room 2, a kitchen 3,
It is composed of 4 Japanese-style rooms and 5 wide rooms, of which 1 is the living room.
Is made up of two housing units 10 and 11, and the dining room 2 has one
It consists of 12 individual housing units. These housing units 10 to 12 each include a box-shaped frame composed of columns 13 arranged at four corners and long-side beams 14 and short-side beams 15 connecting these columns 13.

In the housing units 10 to 12, the floor is constructed by the following procedure using the long plate-like flooring.

Work in the factory First, in the factory, after forming the frame of each housing unit 10 to 12 from the pillars 13 and the beams 14 and 15, the beams 14 and 15 below are formed.
Particle board 16 (No.
(See Figures 4 and 5). Then, a plurality of long plate-like floorings 17 are arranged on the particle board 16. The flooring 17 has a groove 17A formed at a predetermined position on the upper surface thereof so as to extend in the longitudinal direction and the direction orthogonal to this.
In addition, in FIG. 2 showing a cross section in the short side direction, a convex portion 17B is formed at the right end, and a concave portion 17C is formed at the left end.
Further, the upper surfaces of these end portions are chamfered. At this time, the longitudinal direction of the flooring 17 is 10-12
While being parallel to the long-side beam (14), the convex portion (17B) and the concave portion (17C) of the adjacent flooring (17) are fitted together.

Work in the field After each housing unit 10 to 12 in which the flooring 17 is lined up and other housing units are transported to the site, these units are assembled on a foundation not shown. After that, the 4th and 5th
As shown in the figure, a long flat particle board 18 is provided between adjacent housing units, for example, long board beams 18 between the particle boards 16 arranged in two housing units 10 and 11 constituting the living room 1, respectively. Place on top of 14. Then, from the top of this particle board 18, a long plate-shaped joint material 19
Are arranged along the long side beam 14. This joint material 19
A groove 19A is formed at a predetermined position on the upper surface thereof so as to extend in the longitudinal direction and a direction orthogonal to the longitudinal direction, and a cross section in the short side direction is shown in FIG. The engaging projection 19B is formed. Further, the upper surfaces of these end portions are chamfered.

When arranging this joint material 19, the tip of the protrusion 19B at the left end in the figure of the joint material 19 is attached to the left housing unit 1
A predetermined length S is cut so as not to interfere with the flooring 17 of 0, the lower surface of the projection 19B is brought into contact with the upper surface 17D of the convex portion of the flooring 17, and the right end is the right end of the flooring 16 of the left housing unit 11. Contact with the
An adhesive is applied to the connection points between the joint material 19 and the flooring 17 and the particle board 16. The joint material 19 is fixed by temporary nails 20 until the adhesive dries.

The joint material 19 is arranged between the flooring 16 also between the housing unit 11 forming the living room 1 and the housing unit 12 forming the dining room 2 by the same procedure as described above.

According to this embodiment, each housing unit 10-12
In the factory, a plurality of flooring 17 are lined up on the particle board 16 in advance and the joint material 19 is arranged between the flooring 16 of the adjacent housing units 10 to 12 at the site, which shortens the construction period at the site. Moreover, since the projections 16B of the joint material 19 cover the convex portions 16B of the flooring 16, the joint between the flooring 16 and the joint material 19 is not conspicuous. In particular, since the particle board 16 and the flooring 17 are installed on each of the housing units 10 to 12 in a factory where product management is well done, the installation accuracy can be improved. Further, since the base material 18 is arranged below the joint material 19, even if a person rides on the joint material 19, it does not bend.

Although the flooring 17 is arranged in parallel with the long-side beam 14 of the housing units 10 to 12 in the above-described embodiment, the flooring 17 is arranged in the direction orthogonal to the long-side beam 14 as shown in FIGS. Good. At this time, since the ends in the short side direction of the flooring 17 are substantially right angles, the thickness of the joint material 19 is made slightly thicker than that of the flooring 17, and the joint material 19
A chamfer is formed on the upper end of the sloped surface continuous with the upper surface of the flooring 17. Also, the groove 19A on the upper surface of this joint material 19
Is formed on the same line as the groove 17A extending in the longitudinal direction of the flooring 17, and the joint between the flooring 17 and the joint material 19 is difficult to see.

〔The invention's effect〕

According to the present invention as described above, there is an effect that the construction period at the site can be shortened, the construction accuracy is high, and the joint material does not bend even when a person rides on it.
