Abstract

PROBLEM TO BE SOLVED: To prevent a surface plate for a ceiling from waving in the case of using one surface plate for a ceiling even when intervals between ceiling joists are widened, to uniform the pitch of ceiling joists on the first and second stories, and to reduce cost and to speed up construction by reducing the number of ceiling joists to be used. SOLUTION: A longitudinally downward protruded stripe 2 is protruded at the approximately center location of the width direction of a narrow metal plate to constitute a joiner 3. The joiners 3 are arranged on the lower surface parts of a plurality of ceiling joists 4 arranged in parallel at intervals in such a way as to intersect the ceiling joists 4 at right angels. Surface plates 5 for a ceiling are arranged over the lower surface parts of the plurality of ceiling joists 4 arranged at intervals. Then the side faces of the surface plates 5 for a ceiling are brought into contact with the protruded stripes 2 of the joiners 3 at the adjacent sections of the surface plates 5 for a ceiling, and the back surfaces of the end parts of the surface plates 5 for a ceiling are brought into contact with the lower surfaces of the joiners 3. The end parts of the surface plates 5 for a ceiling are fastened to the ceiling joints 4 by fastening devices 6 via the joiners 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling structure in which a ceiling face plate is attached to a ridge.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 6 and 7, a plurality of ridges 4 are juxtaposed at an interval, and a ceiling portion such as a gypsum board extends over the lower surface of the plurality of ridges 4. As shown in FIG. The face plate 5 is arranged and fixed to the field edge 4 by a fixing tool such as a nail or a screw.

[0003] By the way, as the ceiling face plate 5 such as a gypsum board, there are a case where two gypsum boards are stacked and a case where one gypsum board is used. For example, on the first floor, 12.5 mm thick,
Two 9.5-mm-thick ones are used. On the second floor, one 9.5-mm-thick one is used. Since the ceiling face plate 5 in which two gypsum boards are stacked has high strength and is unlikely to generate waving, the interval between the bezels 4 can be widened (for example, the pitch between the bezels 4 can be 455 mm). Since the ceiling face plate 5 composed of one gypsum board has a low strength, if the distance between the ridges 4 is widened, undulation is likely to occur, and therefore, the distance between the ridges 4 is smaller than that of two piles. It is necessary to make it narrow (for example, the pitch between the ridges 4 is made 364 mm as in the conventional example shown in FIG. 6).

As described above, in the related art, the distance between the ridges 4 differs between the case of the ceiling face plate 5 composed of one gypsum board and the case of the ceiling face plate 5 in which two gypsum boards are stacked. Therefore, there is a problem that the pitches of the ridges 4 cannot be unified on the first and second floors, and in the case of the ceiling face plate 5 composed of one gypsum board, the interval between the ridges 4 is narrow. There is a problem that the number of used 4 increases, the material cost increases, and the construction is troublesome and time-consuming.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and even if the distance between the field margins is widened, the present invention has been made.
When using two ceiling panels, the ceiling panels are prevented from waving, the pitch of the ridges on the first and second floors can be unified, and the number of ridges used can be reduced to reduce costs and speed construction. It is an object of the present invention to provide a ceiling structure that can be easily sewn.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a ceiling structure according to the present invention comprises a long metal plate having a longitudinally downwardly projecting ridge 2 protruding at a substantially central position in the width direction of the elongated metal plate. 3 and a plurality of ridges 4 arranged side by side at intervals.
A joiner 3 is arranged at right angles to the edge 4 at the lower surface of the ceiling, and a ceiling face plate 5 is arranged so as to extend over the lower surface of the plurality of edge 4 arranged side by side with an interval therebetween. At an adjacent position, the side end surface of the ceiling face plate 5 abuts against the ridge of the joiner 3 and the end back surface of the ceiling face plate 5 is joined to the joiner 3.
And an end portion of the ceiling face plate 5 is fixed to the field edge 4 via a joiner 3 with a fixing tool 6. With such a configuration, between the edge 4, the upper surface end of the ceiling face plate 5 abuts on the joiner 3 and is regulated, thereby preventing waving. The gap between them (pitch of the ridges 4) can be widened. Therefore, even if the gaps between the ridges 4 are unified with the gap size when the ceiling face plate 5 in which two gypsum boards are piled up is used, the gypsum This can be achieved by mounting the ceiling face plate 5 composed of one board so as not to be wavy.

It is preferable that the joiner 3 is temporarily fixed to the lower surface of the ridge 4 by the double-sided adhesive tape 7. With such a configuration, the joiner 3 can be temporarily temporarily fixed to the ridge 4 and the workability is improved.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the accompanying drawings.

FIG. 3 shows a joiner 3 of the present invention. The joiner 3 is formed by projecting a downwardly protruding ridge 2 at a substantially central position in the width direction of the elongated thin metal plate over the longitudinal direction. In the embodiment shown in the attached drawings, the central portion of the thin metal plate is bent downward. Ridge 2 is formed. The thin metal plate has a thickness of 1 mm or less, preferably 0.5 mm or less, and is formed by bending the thin metal plate.

The field edge 4 is formed by bending a thin metal plate, and is formed by, for example, bending into a rectangular tube shape and connecting both ends. The thin metal plate constituting the edge 4 has a thickness of 1 mm or less, preferably 0.5 mm or less. A plurality of ridges 4 having the above configuration are arranged side by side at predetermined intervals. The distance between the ridge 4 and the ridge 4 is determined by the width of the ridge 4 in the case of using the ceiling face plate 5 in which two gypsum boards are stacked.
The width is set to be the same as the interval between them.
The interval between them is の of the module (module length is 91
In the case of 0 mm, the pitch between the edges 4 is set to be as wide as 455 mm).

When arranging and mounting the ceiling face plate 5 over the lower surface of the plurality of side edges 4 arranged side by side, as shown in FIG. 4 is arranged and mounted orthogonally to the edge 4 on the lower surface of the base 4. In this case, the upper surface of the joiner 3 is temporarily fixed to the lower surface of the ridge 4 with a double-sided adhesive tape 7. The joining position of the joiner 3 is the downward projecting ridge 2 of the joiner 3.
Of the ceiling face plate 5 to be constructed later.

After the joiners 3 are attached to the lower surfaces of the plurality of ridges 4 at right angles as described above, the ceiling face plate 5 is arranged so as to cover the lower surfaces of the plurality of ridges 4 arranged side by side with an interval therebetween. Then, the side end face of the ceiling face plate 5 abuts on the ridge of the joiner 3 at the location where the ceiling face plates 5 are adjacent to each other, and the end back surface of the ceiling face plate 5 abuts on the lower surface of the joiner 3. The end of the face plate 5 is fixed to the ridge 4 via the joiner 3 with the fixing tool 6. In this case, by joining the joiner 3 to the plurality of ridges 4, unevenness at the level of the plurality of ridges 4 is eliminated.

As the ceiling face plate 5 for forming the Western style ceiling, for example, there are a case where two gypsum boards are stacked and a case where one gypsum board is used. In the embodiment, a 12.5 mm thick gypsum board and a 9.5 mm thick gypsum board are stacked on the first floor, and one 9.5 mm thick gypsum board is used on the second floor. Here, since the interval between the bezels 4 is set to the width in the case of using the ceiling face plate 5 in which two gypsum boards are stacked as described above, the two ceiling face plates 5 in the first floor are used. Not to wave, even if the ceiling face plate 5 composed of one gypsum board is used for the ceiling face plate 5 on the second floor, the upper surface of the ceiling face plate 5 between the bezels 4 The end portion is brought into contact with the joiner 3 so as to be in a regulated state to prevent waving. Therefore, even if the interval between the bezels 4 is unified with the gap size when the ceiling face plate 5 in which two gypsum boards are stacked as described above (for example, the pitch between the bezels 4 is 455 mm), The ceiling face plate 5 composed of one gypsum board can be attached without waving.

Here, despite the fact that the joiner 3 is formed by bending a thin metal plate, the presence of the ridges 2 makes it difficult to deform and the strength is high, so that the waving of the ceiling face plate 5 is reduced. 3 can be regulated. The downward ridges 2 are present at joints between the ends of the adjacent ceiling face plates 5, and when filling the joints with the caulking agent, the downward ridges 2 serve as a backup material. is there. Further, the ceiling face plate 5 can be positioned by abutting the side end of the ceiling face plate 5 against the downwardly protruding ridge 2.

In the case of a Japanese-style ceiling, the joiner 3 is mounted on and fixed to the upper surface of the edge 4 at right angles to a plurality of edge 4 arranged side by side at a predetermined interval. It is designed to eliminate level irregularities. Also,
As described above, the pitch between the ridges 4 on each of the first floor and the second floor in the same building can be set to 455 mm. The Japanese ceiling material 10 can be fixed to the lower surface of the field edge 4 by arranging the Japanese ceiling material 10 in parallel with the field edge 4 as shown in FIGS. It is what becomes. In other words, the commercially available Japanese ceiling material 10 is generally constructed by fixing the base bar 10b to the back of a face plate 10a such as a gypsum board having a wood-grained decorative layer such as cedar mat on the surface. The width of the material 10 is generally 455 mm.
By setting it to 55 mm, even if the Japanese ceiling material 10 is arranged in parallel to the edge 4 as shown in FIG. 4, the base beam 10 b at the end in the width direction of the Japanese ceiling material 10 is used as shown in FIG. 5. The lower surface of the edge 4 is fixed to one half of the lower surface by a fixing tool 6 such as a nail or a screw, and the base rail 10b of another adjacent Japanese ceiling material 10 is in contact with the other half of the lower surface of the field edge 4. At the same time, it can be attached by fitting the projection 11 of the base bar 10b into the recess 12 of the base bar 10b of the Japanese ceiling material 10 which has already been fixed.

In the attached drawings, reference numeral 15 denotes a field edge 4.
A suspension lug receiver for mounting a suspension tree for suspending a central part in the longitudinal direction of the rim 4 is shown. Reference numeral 16 denotes a ridge runner for mounting both ends of the ridge 4.

[0017]

As described above, according to the first aspect of the present invention, a joiner is formed by projecting a downwardly projecting ridge in the longitudinal direction substantially at the center of the elongated metal plate in the width direction. ,
A joiner is arranged on the lower surface of the plurality of side edges arranged side by side at right angles to the field edge, and a ceiling face plate is arranged so as to extend over the lower side of the plurality of side edges arranged side by side across the distance. In a position adjacent to the ceiling face plates, the side end surface of the ceiling face plate abuts on the ridge of the joiner, and the end back surface of the ceiling face plate abuts on the lower surface of the joiner, and the end of the ceiling face plate passes through the joiner. The edge of the ceiling face plate is regulated by the joiner because it is fixed to the ridge by the fastener, and the ceiling face undulates when one ceiling face plate is used even if the interval between the ridges is widened. This makes it possible to cope with various things such as one composed of one gypsum board as a ceiling face plate, and two laminated gypsum boards, and as a result, in the same building, On the first and second floor Can unify the pitch of the edge, also,
This reduces costs by reducing the number of ridges used and speeds construction.

According to the second aspect of the present invention, in addition to the effect of the first aspect, the joiner is temporarily fixed to the lower surface of the field edge by a double-sided adhesive tape. Can be easily temporarily fixed to the field edge, and the workability is improved.
