Description

[Detailed Description of the Invention] The present invention relates to an improvement in the structure of the end attachment portion of a ceiling board.

In the conventional example, the circumferential edge 12 as shown in FIG. The ceiling board 26 was placed on the ceiling material placement piece 28 of. In this case, if the angle of 45 degrees is off, or if the angle of the corner of the wall surface 13 is off by more than 90 degrees, a gap will be created at the butt part of the surrounding edge 12, resulting in a disadvantage of reduced airtightness and heat insulation. The drawback was that the finish was poor.

The present invention has been made in view of the drawbacks of the conventional example, and an object of the present invention is to cover the ends of adjacent surrounding edges at the corner portions of the wall surface with the surrounding edges corners, so that the surrounding edges can be improved. To provide a structure of an end attachment part of a ceiling board, which can prevent the occurrence of gaps at the edge parts and improve airtightness in a room.

The present invention will be described in detail below with reference to illustrated embodiments. The base material 15 is arranged horizontally along the wall surface 1 and is fixed to the wall surface 1. The circumferential edge attachment body 16 has a cross section approximately L with the circumferential edge locking piece 3 protruding from the nailing piece 17.
It is a long, letter-shaped product made of extrusion molded aluminum or synthetic resin. At the lower ends of the front and rear surfaces of the circumferential edge locking piece 3, locking saw teeth 18 with the tips facing upward are protruded, and there are also split grooves for imparting elasticity to the circumferential edge locking piece 3. 19 is recessed in the longitudinal direction. This circumferential edge fitting body 16 is arranged along the wall surface 1 through the corner portion, and the circumferential edge fitting body 16
The nailing piece 17 is nailed to the base material 15.
As shown in FIG. 3, the circumferential edge 7 forms a circumferential edge main body 5 with a vertical piece 20 and an inclined piece 22, and a ceiling plate mounting piece 6 is provided on the upper surface of the circumferential edge main body 5. The outer end 21 of the placing piece 6 and the inclined piece part 22 are integrally connected, and the inner end of the ceiling plate placing piece 6 and the vertical piece part 2 are connected integrally.
0 are integrally connected, the inside is hollow, and this is also a long object made by extrusion molding of aluminum or synthetic resin. The ceiling plate mounting piece 6 is formed one step lower than the upper end of the vertical piece 20, and the vertical piece 20 is further provided with a locking groove 4 with an upward opening. A locking protrusion 23 is provided in a protruding manner, the tip of which is directed downward. The surrounding edge corner 24 is the corner part 9 of the wall surface 1 as shown in FIG.
A mounting groove 11 with an upward opening is recessed in a mounting portion 25 that stands up from the surrounding edge corner main body 10, which is formed according to the angle of (usually 90 degrees).
A locking protrusion 23 with a tip facing obliquely downward is provided on the inner surface of the locking member 1 in a protruding manner. Further, the upper surface of the surrounding edge corner main body 10 is formed in the same shape so as to be in close contact with the lower surface of the inclined piece part 22 of the surrounding edge 7, and there are no attachment parts 25 at both ends of the surrounding edge corner main body 10. The ceiling board 8 is made of, for example, a surface material made of polyvinyl chloride filled with a heat insulating material such as foamed resin, and has excellent heat insulation and waterproof properties, and is also lightweight. As shown in FIG. At the same time, the edge 7 is fixed to the edge attachment body 16 by locking the strip 23, and the end of the ceiling board 8 is placed on the ceiling board mounting piece 6, and nailed to the ceiling board mounting piece 6. The ceiling board 8 is held between the pieces 17 and prevents moisture from entering the attic space.
Due to the presence of the time slot 19, the circumferential edge locking piece 3 bends inward and becomes narrower, so that the circumferential edge locking piece 3 and the locking groove 4 can easily engage with each other. When the sawtooth 18 and the protruding portion 23 to be locked are engaged, the surrounding edge locking piece 3 spreads, and the sawtooth 18 and the protruding portion 23 to be locked are completely engaged and will not come off. be. Next, the end portion of the surrounding edge 7 of the corner portion 9 of the wall surface 1 is covered with the surrounding edge corner main body 10 of the surrounding edge corner 24, and the mounting groove 11 of the surrounding edge corner 24 is covered.
The surrounding edge locking piece 3 is inserted inside, and the locking serrations 18 of the surrounding edge locking piece 3 are locked to the locking protrusion 23 of the mounting groove 11. At this time, the upper surface of the edge corner main body 10 is brought into close contact with the lower surface of the inclined piece part 22 of the edge 7, completely closing the gap created at the end of the edge 7, and also filling the cavity inside the edge 7. Seal tightly. In this way, it is possible to completely close the gap that occurs between the ends of the adjacent circumferential edges 7 at the circumferential edge corner 24, which has the advantage of increasing the airtightness of the room. Since the cavity of the edge 7 is sealed, the heat insulation of the surrounding edge 7 can be improved. Moreover, since no gap is formed at the end of the circumferential edge 7, the appearance is very good.

As described above, the present invention involves attaching an edging body around the entire length to a base material that is horizontally fixed along the adjacent wall surface through the corner part, and attaching the edging body that has a ceiling plate mounting piece on the upper surface to the corner part. Since the entire length of the ceiling board except for the outer edge is attached to the circumferential edge attachment body and the end of the ceiling board is placed on the ceiling plate mounting piece, by attaching the circumferential edge to the circumferential edge attachment body, the ceiling panel Not only can the edge of the ceiling board be supported, but also the edge between the edge of the ceiling board and the wall can be neatly closed off with the surrounding edge, and the upper surface can be bent to fit the corner of the wall and the upper surface follows the lower surface of the edge. Since the surrounding edge corners are arranged at the corners of the wall surface, the ends of adjacent surrounding edges are covered at both ends of the surrounding edge corners, and the surrounding edge corners are attached to the surrounding edge attachment body, the corner portion It is possible to cover the area between adjacent circumferential edges at the circumferential edge corner via the circumferential edge, thereby creating a beautiful finish and ensuring airtightness without creating a gap unlike the conventional method in which the edges of the circumferential edges are butted against each other. Furthermore, although it is covered with the surrounding edge corner, the surrounding edge corner can also be attached to the surrounding edge attachment body for attaching the surrounding edge, and furthermore, the ceiling plate can be mounted on the top surface. The circumferential edge having a piece is attached to the circumferential edge attachment body over the entire length excluding the corner portion so that the vertical position can be adjusted freely, and the circumferential edge corner disposed at the corner portion is attached to the circumferential edge attachment body so that the vertical position can be freely adjusted. Therefore, by adjusting the vertical position where the surrounding edge is attached to the surrounding edge attachment body, the height of the ceiling board mounting piece of the surrounding edge can be changed, and the attachment of the surrounding edge corner to the surrounding edge attachment body can be changed. By adjusting the vertical position of the surrounding edge, even if the vertical position of the surrounding edge changes, the surrounding edge corner can be installed to match the surrounding edge, and even if the thickness of the ceiling board changes, the surrounding edge or the surrounding edge corner can be installed. This can be done by adjusting the vertical position of the
