Description

[Detailed description of the invention] (Industrial application field) The invention relates to a ceiling panel used for a ceiling behind a narrow eave.

(Prior Art) A ceiling panel attached to the back of an eave is usually composed of a single panel body having a required area, and is directly attached to a wooden edge by means of an attachment means such as a nail.

Also, Japanese Patent Publication No. 53-16606 discloses that a channel-shaped field edge is previously lined at a predetermined position on a surface, and a hook portion of a clip hooked on the field edge is bent to fix the field edge and a ceiling panel to a field edge receiver. By doing so, a ceiling panel that improves workability is disclosed.

(Problems to be solved by the invention) However, in the former case, not only the heads of the nails and the like appear in the appearance, but also the work itself is skillful, because the ceiling panel behind the eaves is attached to the wooden edge with a nail or the like. In such a case, the unit construction method in a current house is an obstacle to improving workability such as shortening the construction period.

If the ceiling panel is lined with a field edge in advance, the above-mentioned appearance problems can be solved, but a conventional structure is used for the field edge and this is simply fixed in advance to the back of the ceiling panel. In addition, since the clip is bent and attached to the field support, the work takes a long time and can be performed only from a certain direction.

In addition, the space under the eaves often has a lower pressure than the space behind the eaves due to the passage of wind. For this reason, if not securely attached, the ceiling panel may rattle or fall off.

The present invention has been made in view of the above-mentioned problems, and aims to prevent fixing tools such as nails from being exposed on the surface of a ceiling panel main body, and to shorten work time and improve workability. An object of the present invention is to provide an eaves ceiling panel that can be fixed to a ceiling basement.

(Means for Solving the Problems) The present invention is characterized in that the following configuration is provided to achieve the above object. In other words, the eaves-behind ceiling panel is formed by previously fixing a field edge formed of a thin steel material at a predetermined position on the back surface of the eaves-behind ceiling panel body,
The rim comprises a main body fixed to the back surface of the ceiling panel main body, and a fitting portion which is integrally formed on an upper surface of the main body and is elastically fitted into a lip portion of the rim receiver. I have. The main body portion of the field edge includes a bottom surface in contact with the back of the eaves ceiling panel main body, both side surfaces formed to rise on both sides of the bottom surface, and the field edge portion inward from the upper ends of these both side surfaces. And a top surface extending horizontally to a position leaving an interval substantially equal to the width of the receiving lip groove. The fitting portion of the field edge is composed of a pair of right and left fitting pieces rising from the inner end of the upper surface of the main body portion, and the fitting piece has a substantially rectangular cross section, with the bent portion facing outward. And the distance between the tip portions is set to be smaller than the width of the lip groove of the field edge receiver. Further, between the lower portion of the fitting piece and the upper surface of the main body portion, there is formed an acute-angled continuous groove for fitting and locking while making the lip portion of the field margin receiver abut on the upper surface of the main body portion. is there.

(Effect) In the eaves-behind ceiling panel having the above configuration, the eaves-behind ceiling panel is lifted and the fitting portion of the ridge fixed to the back surface of the panel body is pressed into the downward lip groove of the ridge receiver. The mating piece is pushed by the lip edge of the ridge receiver and is elastically deformed, and the lip edge is fitted into the acute-angled continuous groove between the lower part of the fitting piece and the upper surface of the rim body, The eaves back ceiling panel is fixed with one touch by the above-mentioned connection of the ridge and the ridge support.

When the fitting portion is pressed against the edge of the lip, the fitting piece having a substantially L-shaped cross-section reliably bends and deforms, and after the lip edge passes through the bent portion, the fitting piece quickly returns to its original shape. It returns elastically. The edge of the lip portion is securely held in the continuous acute-angle groove between the lower portion of the restored fitting piece and the upper surface of the main body without play while keeping the surface in contact with the upper surface of the original portion.

The edge of the lip is supported on the upper surface of the main body portion of the ridge, so that the acting force does not affect the main body of the eaves ceiling panel.

In addition, since the ridge is fixed from the back side of the eaves ceiling panel main body, the head of the nail or the like is not exposed on the surface of the eaves back ceiling panel main body.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

FIG. 1 is a perspective view of the exterior of an eaves ceiling panel according to an embodiment of the present invention. In the figure, reference numeral 1 denotes an eaves ceiling panel body made of a scallop board or the like, which is appropriately sized according to the ceiling surface to be constructed. Formed.

Reference numeral 2 denotes a ridge fixed at a predetermined position on the back of the eaves ceiling panel main body 1, that is, a position corresponding to a ridge receiver 3 of a ceiling base on which the panel is assembled. The ridge 2 is formed of a thin steel material. A main body 21 and a fitting part 22 are provided.

As shown in FIG. 2, the main body 21 of the ridge 2 has a bottom surface 21a screwed to the back surface of the eaves ceiling panel main body 1, two side surfaces 21b formed on both sides of the bottom surface 21a, Upper surface 21c extending a predetermined length inward from the upper end of surface 21b
And The inner end of the upper surface 21c of the main body is opposed to the lip groove of the lip groove-shaped steel material 3 to which the ridge 2 is attached at a distance w1 substantially equal to that of the lip groove. Code 31
Is a lip part of the ridge 3.

The fitting portion 22 of the ridge 2 is composed of a pair of right and left fitting pieces 22a, 22a having a substantially rectangular cross section and rising integrally from the inner end of the upper surface 21c of the main body. Both fitting pieces 22a have bent portions on the outside,
The interval w2 between the front end portions is provided symmetrically so as to be smaller than the width of the lip groove of the above-described edge support 3.

In the figure, reference numeral 23 denotes an acute-angled continuous groove formed by the upper surface 21c of the edge main body portion and the lower portion of the fitting piece 22a.
The tip of the lip 31 is fitted with its outer surface in contact with the upper surface 21c of the main body.

Further, if an adhesive or the like is applied between the ridge 2 and the ceiling panel body 1, stronger bonding between them can be achieved.

The state of use of the eaves ceiling panel having the above structure will be described with reference to FIGS. The field margin receiver 3 disposed at a predetermined position in the space above the ceiling is suspended by the suspension bolts 4 with the lip portion 31 down, and the reinforcing stay 5 prevents displacement or runout.
