Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a surrounding edge device installed at the joint between a ceiling and a wall.

[Background technology]

As shown in FIG. 1, the conventional surrounding edge device has a front upstanding piece 7a of a surrounding edge 6a formed of a hard thermoplastic synthetic resin in contact with a ceiling plate 13 to achieve airtightness.

However, due to aging, the ceiling plate 13 warps, creating a gap A between the ceiling plate 13 and the surrounding edge 6a.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and its purpose is to absorb the warping of the ceiling board due to aging by absorbing it through elastic displacement on both the front and back sides of the ceiling board, so that it can last for a long period of time. To provide a circumferential edge device which can maintain airtightness, prevent external force from reaching the fitting part of ceiling panels even if they protrude to the back side of the ceiling panels, and has excellent workability.

[Disclosure of invention]

The surrounding edge device of the present invention has a hanging piece 4 forming a locking receiving part 5.
A ceiling in which a horizontal mounting piece 2 for attaching to a ceiling base material 12 extends forward from the upper end, and slopes downward toward the hanging piece 4 side over the entire length of the horizontal mounting piece 2 at a position entered from the front end of the horizontal mounting piece 2. A receiver formed by extending an inclined piece 3 for abutting against the back surface of the plate 13 and dividing this inclined piece 3 into strips 22 in the length direction is called a member 1 and has an approximately U shape.
An elastic gasket 8 is provided at the upper end of the front upright piece 7 in the shape of a letter for elastically contacting the surface of the ceiling plate 13 over its entire length.
In addition, the rear upright piece 9 is provided with a surrounding edge main body 6 formed by providing a locking part 10 for locking the locking part 5 of the member 1. With this configuration, the above object can be achieved. It is something that

That is, the receiver allows the inclined piece 3 of the member 1 and the elastic gasket 8 of the surrounding edge body 6 to come into elastic contact with the ceiling plate 13 on both the front and back sides, and the ceiling plate 13 is warped due to aging. Even if the elastic packing 8 shrinks, this can be absorbed by the elastic displacement on both the front and back sides of the ceiling plate 13 and the airtightness can be maintained for a long period of time.Furthermore, even if the elastic packing 8 contracts, this can be compensated for by the elastic displacement of the inclined piece on the back side. Moreover, since the inclined piece is divided into thin pieces 22, even if the fitting portions of the ceiling panels 13 protrude toward the back side of the ceiling panels 13, no external force is applied to them, resulting in excellent workability. It is.

Embodiments of the present invention will be described in detail below based on the drawings.

The receiver member 1 is made of hard vinyl chloride resin and is formed into a longitudinal section.

The receiver has an inclined piece 3 extending downward from the lower surface of the middle part of the mounting horizontal piece 2 of the member 1.

This inclined piece 3 is provided over the entire length of the mounting horizontal piece 2, and is inclined downward toward the rear side and curved convexly toward the front.

Thus, when the back side of the ceiling plate 13 comes into contact with the front surface of the inclined piece 3, the inclined piece 3 is elastically displaced to the back side.

The receiver has a hanging piece 14 suspended substantially parallel to the further back side of the hanging piece 4 of the member 1.

This tooth-like stepped portion 15 is provided on the inner surface of each of the hanging piece 4 and the hanging piece material 14 to form the locking receiving portion 5.

The surrounding edge main body 6 has a substantially U-shape and is formed by extrusion molding a hard vinyl chloride resin.

The horizontal horizontal piece 16 of the surrounding edge main body 6 is used as a decorative edge, and the front and rear surfaces of the rear upstanding piece 9 are provided with serrated step portions 15 to form a locking member 10.

A horizontal piece 17 is provided at the tip of the front upright piece 7 toward the back side, and an elastic packing 8 integrally formed with the horizontal piece 17 from soft vinyl chloride resin is provided on the upper surface of this horizontal piece 17.

The elastic packing 8 is inclined upwardly in the front and is convexly curved in the front so that the elastic packing 8 can come into surface contact with the lower surface of the ceiling plate 13.

As shown in FIGS. 4 and 5, the receiver attaches the mounting horizontal piece 2 of the member 1 to the ceiling base material 12 using nails as an example of the fixture 11.

A ceiling board 13 is attached to a ceiling base material 12 located at an intermediate position on the ceiling.

The receiver, which is attached to the ceiling base material 12 in contact with the wall 18, brings the back end of the ceiling plate 12 into contact with the inclined piece 3 of the member 1.

Then, the locking member 10 of the circumferential edge body 6 is engaged with the locking receiving portion 5 of the member 1, and the elastic packing 8 of the circumferential edge body 6 is brought into elastic contact with the surface of the ceiling plate 13.

In this way, the members 1 are placed on the front and back sides of the ceiling board 13.
By elastically abutting the surrounding edge main body 6, even if the ceiling plate 13 warps due to changes over time, this can be absorbed and airtightness can be maintained over a long period of time.

Furthermore, even if the elastic packing 8 contracts over time, this can be compensated for by the elastic change of the inclined piece 3.

A recess is provided in the ceiling plate 13, and the insulation material 1 is placed in this recess.
It is full of 9.

As shown in FIG. 6, the ceiling plate 13 is formed with a lug 20 and a fitting lug 21 that can be fitted with the lug 20.

Thus, the ceiling plates 13 can be connected to each other by inserting and fitting the lug 20 of the ceiling plate 13 into the fitting lug 21 of the adjacent ceiling plate 13.

As shown in FIG. 2, the inclined piece 3 of member 1 is
It is divided into strips 22 of approximately the same length in the length direction.

As shown in FIGS. 4 and 6, the strip 22 at the connection point of the ceiling plate 13 is broken off to prevent the inclined piece 3 from coming into contact with the lug 20 and the fitting lug 21.

In this way, no external force is applied to the fitting portion of the ceiling plate 13, and the construction is simple and the fitting portion is free from distortion.

[Effect of idea]

In the present invention, a horizontal mounting piece for attaching to the ceiling base material extends forward from the upper end of the hanging piece that forms the locking receptacle, and at a position inserted from the front end of this horizontal mounting piece, the vertical direction of the hanging piece is extended forward. The receiver, which is formed by extending an inclined piece to come into contact with the back side of the ceiling board that hangs downwardly over the entire length and slopes downwardly on one side, is attached to the upper end of the approximately U-shaped front upright piece over the entire length of the member. In addition to providing an elastic gasket to make elastic contact with the surface of the ceiling board, the rear upright piece is provided with a retaining part for retaining the member, so that the retainer is secured from the surrounding edge body formed by providing a retaining part for retaining the member. Attach the mounting horizontal piece of the component to the ceiling base material, bring the back of the ceiling board into contact with the inclined piece, and lock the locking part of the surrounding edge body to the locking part of the member, and attach the elastic packing to the surface of the ceiling board. Therefore, the support allows the inclined piece of the member and the elastic gasket of the surrounding edge body to be brought into elastic contact with the ceiling plate on both the front and back sides. Even if the ceiling board warps due to changes over time, it can be absorbed by the elastic displacement on both the front and back sides of the ceiling board and maintain its airtightness over a long period of time.Furthermore, even if the elastic packing shrinks, it can be bent on the back side. This can be compensated for by the elastic displacement of the inclined piece of the member, and since the support is formed by dividing the inclined piece of the member into thin pieces in the length direction, the fitting part between the ceiling plates is on the back side of the ceiling plate. If the ceiling panels protrude, by breaking off the thin strips of the slanted pieces at the connection points between the ceiling panels when installing the ceiling panels, you can prevent external forces from reaching the ceiling panels and cause distortion in the mating parts. It is easy to install ceiling panels and has excellent workability.
