Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peripheral edge for a ceiling and a ceiling structure using the same.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, when constructing a ceiling in a wooden construction, field trim receivers (not shown) are arranged at intervals of about 900 mm and fixed to a hanging tree (not shown). The field edge A is attached at a predetermined interval in a direction orthogonal to the field edge receiver, and at the wall edge of the end portion of the field edge A, the field edge B is attached in a direction orthogonal to the field edge as a ceiling base. , The ceiling board C was attached to the lower surface of these margins A and B. In addition, a peripheral edge E is attached to the lower surface side of the end portion of the ceiling plate C along the wall surface D to apply makeup.

[0003]

Since it is necessary for an operator to look up at such a ceiling construction, it is difficult to perform the work.
In particular, the work of attaching the field rim B to the end of the field rim A at the wall edge so as to be orthogonal to each other requires tightly connecting the field rims one by one, and thus the work is troublesome and time-consuming. In addition, since the work of the peripheral edge E needs to be performed after the ceiling work is completed, the work has been troublesome twice.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to save labor in ceiling construction by using a rim having a specific shape.

In order to achieve this object, the present invention according to claim 1 is a long peripheral edge which is used by being fixed to a wall surface around a ceiling and which is provided on the side opposite to the fixed surface in contact with the wall surface. A groove into which the end portion is fitted is formed to extend over substantially the entire length in the longitudinal direction, and a notch in which the end portion of the field edge is fitted is formed in the first front protrusion located above the ceiling material fitting groove. It is formed so as to communicate with the ceiling material fitting groove at a predetermined interval, and the second front protruding portion located below the ceiling material fitting groove and the downward extending portion continuous below the second front protruding portion form a decorative surface. Characterize.

According to a second aspect of the present invention, the fixing surface of the peripheral edge for ceiling according to the first aspect is fixed to a wall surface, and both ends of the field edge are fitted into the notches of the opposing peripheral edge to hang it. The ceiling structure is characterized in that both ends of the ceiling material are fitted and attached to the ceiling material fitting grooves at the opposite peripheral edges while being passed, and the ceiling material is fixed to the field edge.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION With reference to FIGS. 1 to 4, description will be given of a rim according to an embodiment of the present invention and a ceiling structure using the rim.

Reference numeral 10 is a peripheral edge formed from a wood material or a synthetic resin material as a long member having a substantially F-shaped cross section, and is opposite to the fixed surface 11 (front surface) which is in contact with the wall material 1 for providing a wall surface.
In addition, a ceiling material fitting groove 14 having a required depth is formed between the first front protrusion 12 and the second front protrusion 13 so as to continuously extend over substantially the entire length in the longitudinal direction.

A downward extension portion 15 is provided below the second front protrusion portion 13 and constitutes a decorative surface of the peripheral edge 10. In this embodiment, the surfaces of the second front protrusion 13 and the lower extension 15 are configured to give a continuous curved decorative surface.

Notches 16 for fitting the ends of the field edge 2 are formed in the first front protrusion 12 so as to communicate with the ceiling material fitting groove 14 at predetermined intervals.

The peripheral edge 10 is fixed to the fixing surface 11 thereof.
After closely contacting the wall material 1 with the wall material 1 at a predetermined position around the ceiling and fixing it at an opposing position by an arbitrary means such as a fixing tool such as a nail or a screw, an adhesive, a double-sided tape or the like, the notch of the opposing peripheral edges 10 and 10 is formed. 16 and 16, both ends of each field edge 2 are fitted and bridged, and both ends of the ceiling material 3 are fitted and attached to the ceiling material fitting grooves 14 and 14, fixing tools such as nails and screws, and adhesives. The ceiling material 3 is fixed to the lower surface of the field edges 2 and 2 by any means such as double-sided tape. Preferably, the opposite edges 10, 10
Separately, a plurality of field edges (not shown) are attached at a predetermined interval so as to be orthogonal to the plurality of field edges 2, 2 ... The ceiling material 3 is fixed to the lower surface.

[0012]

EFFECTS OF THE INVENTION According to the present invention, it is not necessary to attach a field edge in a direction orthogonal to the wall edge at the wall edge of the field edge, and only the field edge is bridged between the opposing peripheral edges. The ceiling base can be formed with.

Moreover, notches are formed in advance on the upper surface of the peripheral edge at predetermined intervals, and the positioning of the field edges is automatically performed by fitting the ends of the field edges into the notches. Therefore, it is possible to significantly reduce the time and effort required to construct the ceiling.

Also, the ceiling material can be mounted by inserting it into the fitting groove of the peripheral edge, and the work can be performed relatively easily even when looking up.

Further, the lower part of the peripheral edge gives a decorative surface similar to that of the conventional peripheral edge, and has both the function of supporting the end of the field edge and the function of the peripheral edge for cosmetic purposes. Therefore, it is not necessary to attach the peripheral edge after the ceiling construction is completed unlike the conventional art.
