Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a method for constructing a ceiling in a Japanese-style room of an industrialized house in which a plurality of housing units are assembled 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. This house also has a type having a Japanese-style room like a house other than an industrialized house, and this Japanese-style room is composed of a plurality of housing units.

Although it is necessary to construct a ceiling in a Japanese-style room of an industrialized house, conventionally, on site, a plurality of ceiling materials having recesses at both ends from the ends of a plurality of housing units that make up the Japanese-style room are fitted into the recess at both ends. There are some that are connected in sequence through the joint material.

[Problems to be Solved by the Invention]

However, in the above-mentioned conventional example, since a plurality of ceiling materials are connected on site, work time for this is required, and it is not possible to sufficiently shorten the construction period required for industrialized houses. There is.

An object of the present invention is to provide a method for constructing a ceiling for a Japanese-style room in an industrialized house, which can shorten the construction period at the site and which does not show the joint between the joint material and the ceiling material.

[Means and Actions for Solving the Problems]

The present invention is a method of constructing a ceiling on a plurality of housing units that constitute a Japanese-style room in an industrialized house in which a plurality of housing units are combined on site, and a plurality of ceiling materials having recesses at both ends of each housing unit in advance. Are connected to each other with a joint between the housing units adjacent to each other at a predetermined distance via joint materials whose both ends are fitted into the recesses, and then engaged with the lower surface of the joint material provided in the recesses of the ceiling material between adjacent housing units at the site. The protrusions that are formed outward from the lower part of the main body are arranged so as to be separated from the ceiling material by a predetermined distance, thereby reducing the work on site and
It is an object of the present invention to achieve the above object by covering the joint material with the projection of the joint material so that the joint between the ceiling material and the joint material is inconspicuous.

〔Example〕

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

Fig. 1 shows the floor plan of the industrialized house built by the unit construction method, and Fig. 2 shows the ceiling of the Japanese-style room.

In FIG. 1, the first floor of an industrialized house is composed of a living room 1, a dining room 2, a kitchen 3, a Japanese-style room 4, a wide-area 5 and the like, of which the Japanese-style room 4 is composed of two housing units 10 and 11. ing. As shown in FIG. 2, these housing units 10 and 11 are box-shaped frames composed of columns 12 arranged at four corners and long-side beams 13 and short-side beams 14 connecting these columns 12, respectively. Is equipped with.

In the housing units 10 and 11, a floor is constructed by the following procedure using a ceiling material, a joint material and a joint material.

Work in the factory First, in the factory, after forming the frame of each housing unit 10, 12 from the pillars 12 and the beams 13, 14, the inner wall 15 and the outer wall 1
Attach 6 etc. Furthermore, while attaching the field edge 17 to the beams 13 and 14 above each housing unit 10 and 11, the field edge 17
Attach the gypsum board 18 (see Fig. 5 and 6) to the bottom surface of the.

After that, a plurality of long plate-shaped ceiling materials 20 are attached to the lower surface of the plaster board 18 of each of the housing units 10 and 11. This ceiling material
In FIG. 3, 20 is a cross section of the short side,
It is composed of two connecting members 21 each having a recess 21A opened to the outside, and a ceiling plate 20A attached to the lower surfaces of these connecting members 21. When attaching the ceiling material 20 to the gypsum board 18, the longitudinal direction of the ceiling material 20 is made parallel to the long side beams 13 of the housing units 10 and 11, and a rectangular cross section is formed between the concave portions 21A of the adjacent ceiling materials 20. The joint materials (22) are connected to each other with a predetermined distance therebetween in a fitted state.

Further, as shown in FIG. 6, in order to hide the gap between the inner wall 16 and the end of the ceiling member 20 in the longitudinal direction, a turning edge 23 is attached to the inner side of the inner wall 16.

Work at the site After transporting each housing unit 10, 11 with the ceiling material 20 attached to the gypsum board 18 and other housing units to the site,
Assemble these units on a foundation not shown.
After that, the gypsum board 24 for connection is attached between the gypsum boards 18 of the two housing units 10 and 11 constituting the Japanese-style room 4 on the lower surface of the adjacent long-side beam 13. After that, a long plate-shaped joint material 25 is attached to the lower surface of the plaster board 24 along the long side beam 13. The joint member 25 has a groove 25A at the center position of the lower surface of the main body in FIG.
Are formed to extend in the longitudinal direction, and projections 25B that engage with the joint material lower surface 22A are formed outward at the lower ends of both ends of the main body. When attaching the joint material 25, as shown in FIG. 5, the joint material 25 is fixed to the gypsum board 24 with dowels 26 while the connecting agent is applied to the upper surface of the joint material 25.

According to the present embodiment as described above, a plurality of ceiling materials 20 are connected to the housing units 10 and 11 that form the Japanese-style room 4 in advance in the factory by separating them from each other through the joint material 22 for a predetermined time. Joint material 2 for connecting parts of housing units 10 and 11
Since the joint material 25 is disposed between the ceiling material 20 and the ceiling material 20 by a predetermined distance between the two, the construction period on the site can be shortened, and the joint material 22 is covered by the projection 25B of the joint material 25, so that the ceiling The joint between the material 29 and the joint material 25 is inconspicuous. In particular, since the ceiling material 20 and the joint material 25 are connected to each other with the joint material 22 separated by a predetermined distance throughout the entire Japanese-style room 4, the ceiling material 20 and the joint material 25 may be separated on the spot due to an installation error of the joint material 25. Even if the dimension between and is other than the specified value, the joint between the ceiling material 20 and the joint material 25 is inconspicuous.

In the above embodiment, the Japanese-style room 4 has two housing units.
It is composed of 10,11, but a Japanese-style room may be composed of three or more housing units.

Further, the connecting material 21 and the ceiling plate 22 of the ceiling material 20 may be integrally formed.

〔The invention's effect〕

As described above, according to the present invention, there is an effect that the construction period at the site can be shortened and the joint between the joint material and the ceiling material is inconspicuous.
