Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an eaves ceiling structure to be constructed at a narrow place of a ceiling and a field edge used for the structure.

(Prior Art) As a general ceiling structure at the back of a narrow eave at the ceiling, there is a structure in which a ceiling plate is directly attached to a wooden edge by nails or the like. However, in the case of such a structure, the head of a fixing tool such as a nail is exposed on the ceiling surface, and the appearance is poor.

In order to avoid this, as shown in FIG. 6, the connecting pieces A, A 'engaging in a male and female manner are fixed to the back surface of the joint end of the ceiling panel B, and From the lower side of one connecting piece A protruding from the ceiling panel B via a nail C or the like.
Is fixed to the rim D, while the one connecting piece A is engaged with the other connecting piece A 'located inside the joint end of the adjacent ceiling panel B'. As shown in FIG. 7, a back rail F is fixed to a joint end of the ceiling panel E, and a side end of the joint plate H is fitted into a groove G formed at an end portion of the back rail F, thereby forming the ceiling panel E. On the other hand, there is a ceiling structure in which the ceiling panel E is attached to the field edge K by directly fixing the straight fitting I attached to the back rail F to the field edge K with a nail J or the like.

Furthermore, in Japanese Patent Publication No. 53-16606, a channel-like field edge is previously lined at a predetermined position on the back surface of the ceiling panel body, and a hook portion of a clip hooked on the field edge is bent.
There is also disclosed a ceiling structure in which a ridge and a ceiling panel are fixed to a ridge receiver.

(Problems to be Solved by the Invention) However, among the above-mentioned prior arts, those shown in FIGS. 6 and 7 have field edges D and K in which connection fittings and the like are mounted on a field edge receiver (not shown) in the same manner as before. Also, the ceiling panels B, B ', and E are fixed to the field edge by nailing or the like by a worker from below through the connecting pieces A, A' or the straight fitting I.
It takes time for construction work.

In the case where the ridges are lined in advance on the ceiling panel, the ridges themselves adopt the conventional structure, and merely fix the ridges to the backside of the ceiling panel in advance. Since the rim and ceiling panels are attached to the ridge support, not only does the construction work take time in the short-term prefabricated unit construction method, but also
The ceiling panels have to be installed sequentially from a certain direction, and the workability cannot be said to be sufficiently good.

Furthermore, the space under the eaves often has a lower pressure than the space behind the eaves due to the passage of wind. Without this, the ceiling panels may rattle or fall off if not installed securely.

The purpose of the present invention is to prevent the head of nails and screws etc. from being exposed on the surface of the eaves ceiling panel main body, to facilitate the construction work and to reduce the time required for it, and to make the eaves ceiling panel play back. The purpose of the present invention is to provide an underpass ceiling structure that does not cause falling or falling off and a field edge used for the structure.

(Means for Solving the Problems) In order to achieve the above-described object, a field edge of the present invention includes a main body fixed to the back of the eaves ceiling panel main body, a rising portion formed on an upper surface of the main body, and a lip. And a fitting portion which is elastically fitted into a lip groove of the rim receiver made of a channel steel. The main body has a bottom surface which is in contact with the back of the eaves ceiling panel main body, two side surfaces which are formed to rise on both sides of the bottom surface, and a width of the lip groove of the field edge receiver inward from the upper ends of these both side surfaces. And an upper surface extending horizontally to a position leaving substantially equal intervals. The fitting portion 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. The interval between the portions is set so as to be smaller than the interval between the edges of the lip portion of the field edge receiver. And, between the upper surface of the main body and the lower part of the fitting piece of the fitting portion, an acute angle continuous groove is formed for fitting and locking while making the lip portion of the rim receiver abut against the upper surface of the main body portion. Is what is being done.

Moreover, in the eaves-behind ceiling structure according to the present invention, a ridge receiver made of lip grooved steel is disposed at a predetermined position in the ceiling space with the lip groove facing downward. A bottom surface of the edge of the above structure is fixed to a predetermined position on the back of the eaves ceiling panel body. Further, a concave portion for supporting a side end portion of the ceiling panel main body is provided at a lower portion such as an eaves back edge. Then, the side end of the eaves ceiling panel body is fitted into the recess, the fitting part of the ridge on the back surface of the eaves ceiling panel body is fitted into the lip groove of the ridge holder, and the lip portion of the ridge holder The edge is locked in a sharp-angled continuous groove of the field edge.

(Operation) The edge of the above-described configuration has the bottom surface fixed to the back of the eaves ceiling panel body and integrated with the ceiling panel, and the field fitting portion projects upward from the back of the ceiling panel body. Therefore, when the ceiling panel is lifted and the fitting portion is pushed into the downward lip groove of the ridge support, the fitting piece is pushed by the lip edge of the ridge support and is elastically deformed, and the lip portion edge is deformed. The eaves ceiling panel is fixed to the ceiling foundation with a single touch because it is fitted into the continuous groove having an acute angle between the lower portion of the fitting piece and the upper surface of the field edge main body.

When the fitting portion is pressed against the edge of the lip, the fitting piece having a substantially L-shaped cross section is securely bent and deformed. After the edge of the lip has passed the bent portion, the fitting piece quickly becomes the original shape. The elastic return. The edge of the lip portion is securely held without play in a continuous acute-angled groove between the lower portion of the restored fitting piece and the upper surface of the main body, with the surface abutting on the upper surface of the main body.

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.
