Description

[Detailed description of the invention] Purpose of the invention (industrial field of application) This invention relates to an improvement of the joint structure of the surrounding edge of a coffered ceiling.

(Problems to be solved by conventional techniques and ideas) Conventional coffered ceilings were installed by making appropriate modifications to muntins that had been made in advance at a manufacturing factory. In other words, depending on the size of the room, there will be irregular parts around the edges of the four sides,
It was successfully assembled by making the lengths around the four sides to match the size of the room. For example, in the method of creating an oblique abutment surface at the joining end of the circumferential edge 1 as shown in Figure 9, the four corner abutting parts of the circumferential edge 1 must fit properly without any errors, so it is necessary to process them on-site. The process was difficult and difficult to produce as a ready-made product. Furthermore, the surrounding edge 1
Once these are properly installed, the notches for assembling the multiple lattice-like lattice-like lattice frames that are hung horizontally on these circumferential edges 1 must be machined on-site, and that work is also difficult. Ta.

The purpose of this invention is to facilitate the processing of the four corners of the perimeter edge to allow for some degree of error in the length of the perimeter edge, to make the perimeter edge a ready-made product, and to promote the use of ready-made coffered ceilings as a whole.

Structure of the invention (means for solving problems) In other words, as shown in the drawings of the embodiments described later, the invention has a corner post 9 vertically installed in the corner of the room adjacent to the corner 9a facing the room. On the upper surface of the surrounding edge receiving part 5 of the decorative dowel 4, which has an L-shaped cross section by forming notches 7 to be fitted in both sides 9b, there is a cutout 7 that is fitted in both sides 9b, which corresponds to the sides 9b adjacent to this corner 9a. A surrounding edge mounting surface 5a that projects horizontally is formed on the upper surface, and a surrounding edge holding protrusion 6 of the decorative dowel 4 that projects upward at the indoor-facing corner 5b of the surrounding edge receiving portion 5 is formed on the upper surface.
Out of the surrounding edges 1 in which the ends of the grate 2 arranged in a lattice pattern are placed horizontally, the ends of both adjacent edges 1 are placed on the surrounding edge mounting surface 5a so that the length thereof can be freely adjusted. Both circumferential edges 1 of the lever are locked by the circumferential edge holding protrusions 6, and a ceiling plate 3 is attached to the upper surface of these circumferential edges 1 and gables 2.

(Function) Now, the ends of both circumferential edges 1 adjacent to each other are placed on the mounting surface 5a of the circumferential edge receiving portion 5 and are locked to the circumferential edge holding protrusion 6. At this time, both circumferential edges 1 The length can be adjusted within the dimensional range L of the mounting surface 5a.

(Example) An example embodying this invention will be described below with reference to FIGS. 1 to 8.

As shown in FIG. 1, reference numeral 1 denotes a circumferential edge surrounding the four sides of the coffered ceiling, and the ends of a plurality of coffered edges 2 arranged in a lattice pattern are suspended horizontally. Reference numeral 3 denotes a ceiling plate attached to the upper surface of these surrounding edges 1 and coffered edges 2.

Reference numeral 4 denotes a decorative box which is hung horizontally at the four corners of the coffered ceiling with the joint ends of the surrounding edges 1 perpendicular to each other;
As shown in the figure and FIG. 3, the surrounding edge receiving portion 5
A notch 7 is formed on both side surfaces 9b adjacent to the interior facing corner 9a of the corner post 9 vertically installed in the corner of the room, and has an L-shaped cross section. A horizontally projecting mounting surface 5a is formed corresponding to both side surfaces 9b, and a surrounding edge holding protrusion 6 is formed on the upper surface of the mounting surface 5a to project upward at the indoor-facing corner 5b of the surrounding edge receiving portion 5. is formed.

Reference numeral 8 denotes a joining rod that is glued or screwed to the notch 7 of the surrounding edge receiving portion 5, and is aligned so that the lower surface of the receiving portion 5 and the lower surface of the joining rod 8 are flush with each other. As shown in FIG. 4, a notch 10 is formed at the corner facing the column 9 to be fitted into the corner 9a of the column 9, and is fixed to the column 9 with screws or nails. However, this joining rod 8 is not necessarily necessary, and it is also possible to directly fix the decorative dowel 4 to the pillar 9. 11 is the bottom surface of the decorative pole 4 and the joining rod 8
a plate portion that covers each of the lower surfaces of the fifth plate from below;
As shown in the figure, a notch 12 is formed to be fitted into the corner 9a of the pillar 9.

Reference numeral 13 denotes a notch formed on the upper surface of the circumferential edge 1 at part B in FIG. 1 as shown in FIG.
The end of the ke-en 2 is indented. In addition, the seventh
The figure shows the fitting structure of the intersecting part of the bar 2 at section C in FIG. 1, and FIG. 8 at section D in FIG. 1.

Now, as shown in FIG. 2, cutouts 10 and 12 are formed in the joint rod 8 and the dowel portion 11 by a carpenter at the assembly site to fit the pillar 9, and the decorative dowel portion fixed to the joint rod 8 is formed by a carpenter at the assembly site. 4 is connected to the column 9 via the joint rod 8
Fixed. Since the mounting surface 5a on the surrounding edge receiving part 5 of this decorative dowel 4 has an allowable range of the L dimension shown in FIG. The joint ends of the surrounding edges 1 that are adjacent to each other are connected to this receiving portion 5.
The joint end portion may be appropriately cut so that it can be mounted within the range of the above L dimension. Therefore, processing of the four corners of the coffered ceiling becomes very easy. The circumferential edge 1 mounted in this manner is locked to the circumferential edge holding protrusion 6.

Incidentally, it is also possible to make the decorative dowel 4 more expensive by applying carvings or the like to improve its aesthetic appearance.

Effects of the invention In short, according to the invention, even if it is a ready-made muntin, the surrounding edges 1 can be joined as appropriate according to the allowable dimension L of the surrounding edge receiving portion 5 of the decorative dowel 4 depending on the size of the room. Dimensional errors at the ends can be easily adjusted, which has the advantage of improving work efficiency at the coffered ceiling installation site and reducing the cost of installing the coffered ceiling.
