Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a corner joint for a circumferential edge, and more particularly to a corner joint for a circumferential edge for connecting a circumferential edge installed between a ceiling panel and a wall surface at a corner.

Generally, this type of corner joint for a surrounding edge is attached to the ceiling of a bathroom, etc., as shown in FIGS. Fix the receiver 10,
A sawtooth convex portion 11 protrudes downward from the circumferential edge receiver 10
By fitting into the sawtooth recess 7 provided along the entire length of the circumferential edge 3 in the longitudinal direction, the circumferential edge 3 is fixed, and the lower surface of the ceiling panel 2 is held by the upper edge of the front end of the circumferential edge 3. , a corner joint 4 is used to connect the adjacent circumferential edges 3, 3. Conventionally, this corner joint 4 has been formed of hard synthetic resin to form a predetermined angle (generally a right angle) according to the shape of the corner, so the shape of the corner and the shape of the corner joint 4 are different. When the shapes do not match, a gap is created between the circumferential edge 3 and the corner joint 4,
In addition to spoiling the aesthetics, when used in bathrooms, moisture could enter the ceiling through the gaps and cause damage to roofing materials.

The present invention was developed in view of the above points, and its purpose is to be able to accommodate various shapes of corners and to avoid creating gaps between the surrounding edges when connecting the surrounding edges. An object of the present invention is to provide a corner joint for a circumferential edge.

Hereinafter, embodiments of the present invention will be described based on the drawings. The circumferential edge corner joint according to the present invention includes a first circumferential edge 3 attached to the lower surface of the ceiling panel 2 between one wall surface 1 and one side of the ceiling panel 2, and another wall surface 1 adjacent to the wall surface 1. The ceiling panel 2 and both wall surfaces 1, 1 are connected in order to connect the second circumferential edge 3 attached to the lower surface of the ceiling panel 2 between the wall surface 1 and the other side of the ceiling panel 2 corresponding to the wall surface 1. In the circumferential edge corner joint 4 disposed at the corners where the circumferential edges meet, both ends to which the first and second circumferential edges 3, 3 are connected are formed of a hard material, and a center corresponding between both circumferential edges 3, 3 is formed. In this embodiment, there are locking parts 5 and 6 on the back surface of the corner joint 4 for fixing the circumferential edge 3 and the corner joint 4. Here are some outstanding examples. As shown in FIGS. 3 and 4, a sawtooth recess 7 that opens upward and has serrated projections on the inner surface is provided at the rear end of the circumferential edge 3 over the entire length in the longitudinal direction. A gasket 8 such as a rubber sponge is attached to the upper edge over the entire length in the longitudinal direction. The circumferential edge 3 is fixed by fitting the sawtooth concave portion 7 into a sawtooth convex portion 11 having a sawtooth-like protrusion on the outer surface which projects downward from a circumferential edge receiver 10 fixed to the field edge 9. At this time, the circumferential edge holder 10
The ceiling panel 2 is held between the side edge 12 of the roof panel 2 and the gasket 8 on the front upper edge of the circumferential edge 3, and the gasket 2 provides a watertight partition between the room and the attic. Reference numeral 13 in FIG. 4 is a contact for preventing the ceiling panel 2 from wobbling. A corner joint 4 is attached to the corner where the ends of the circumferential edge 3 attached in this manner are butted against each other. In the corner joint 4, both ends where the circumferential edges 3, 3 are connected are made of a hard material such as hard vinyl chloride, and the center portion corresponding between the circumferential edges 3, 3 is made of an elastic material such as soft vinyl chloride. It is formed. Locking portions 5 and 6 are provided at the upper and lower rear ends of both ends of the corner joint 4 to lock the circumferential edge 3 fitted from the side so that it cannot move in other directions. These locking parts 5, 6
This prevents the circumferential edge 3 from being pressed against the wall surface 1 and creating a gap between the seal 8 and the ceiling panel 2 even if there is a gap between the wall surface 1 and the rear surface of the circumferential edge 3. . Note that this corner joint can be applied not only to inside corners but also to outside corners.

As described above, the present invention includes a first surrounding edge attached to the lower surface of the ceiling panel between one wall surface and one side of the ceiling panel, another wall surface adjacent to the wall surface, and a ceiling panel corresponding to the wall surface. In the corner joint for a circumferential edge disposed at a corner where the ceiling panel and both wall surfaces touch in order to connect the second circumferential edge attached to the lower surface of the ceiling panel with the other side of the
and both ends to which the second circumferential edge is connected are formed of a hard material, and a central portion corresponding to both the circumferential edges is formed of an elastic body over the entire width, and the connecting portion with the circumferential edge is By forming both ends of the corner joint with a hard material, it is firmly connected to the circumferential edge and prevents the circumferential edge and the corner joint from coming off inadvertently. Because of this, no matter what angle the wall intersects at the corner, the center part of the corner joint can bend and stretch, allowing the corner joint to adhere to the wall and ceiling panels without any gaps, making it possible to maintain the same The advantage is that corner joints can be used to accommodate corners of various shapes. In addition, since the center part of the corner joint is made of elastic material,
Even if the circumferential edge expands and contracts due to temperature differences in a bathroom or the like, this expansion and contraction can be absorbed by the corner joints, which has the advantage of not detracting from the aesthetics.
