Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a ceiling structure, and more particularly to a connecting structure of a main ceiling margin and a sub-ceiling margin.

(Problems to be solved by conventional technology and device) Conventionally, as a ceiling structure of a building, a store, etc., a sub-ceiling field edge is assembled in a lattice shape and is hung from a main ceiling field edge having a substantially inverted T-shaped cross section. For example, those described in Japanese Utility Model Publication No. 49-129310.

That is, in this one, the engaging recess is formed on the side surface of the rising piece of the elongated body having a substantially inverted T-shaped cross section composed of the lower piece and the rising piece, and the engaging protrusion is formed on the upper surface of the lower piece side end. By erected in the longitudinal direction, a fitting groove having a rising piece and a locking projection as a side wall is formed to form a main ceiling edge, while a lower piece and a rising piece have a substantially inverted T-shaped cross section. The lower end piece of the elongate body is cut off, and a notch recess is formed in the lower part of the rising piece of the part where the lower piece is cut out, and a projection part of the lower end of the rising piece that occurs at the same time is formed in the fitting convex part and A ceiling ceiling edge, a sub-ceiling edge edge is fitted to the main ceiling edge edge, and a rising one end portion of the sub-ceiling edge edge is fitted and locked in a locking recess of a rising piece of the main ceiling edge edge. By engaging and locking the fitting convex part of the sub-ceiling edge in the fitting groove of the lower piece, it is easy to use without using any fittings. It can bind to. Therefore, according to this, by simply fitting the end of the sub-ceiling field edge from above into the portion of the main ceiling field edge where the locking recess is formed, the sub-ceiling field edge can be easily attached to the main ceiling field edge. Can be combined with.

However, in this device, the sub-ceiling field edge is merely fitted and placed on the main-ceiling field edge, so that rattling is likely to occur and the sub-ceiling field edge is easily detached when pushed upward. Therefore, in order to eliminate such a problem, it is conceivable to connect the main ceiling margin and the sub-ceiling margin with a joint fitting, but since this method requires a separate joint fitting, the number of parts is reduced. However, there is a problem that the number is increased and the construction is troublesome.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a connecting structure for a ceiling margin, which can prevent rattling and falling of the auxiliary ceiling margin without using a separate metal fitting, and which has good workability.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a receiving portion having a substantially U-shaped cross-section with an upward opening at the lower end portion of the vertical portion, and has an engaging groove portion at the lower end portion of the vertical portion. A plurality of main parts each having a cross-sectional shape in which a flange portion is laterally extended from an upper end portion of a side wall which forms the receiving portion, and cutout portions having an appropriate width are formed at predetermined intervals in the flange portion. The ceiling rims are hung in parallel from the base of the ceiling and arranged side by side, and have a substantially U-shaped cross section that can be fitted into the cutout portion of the main ceiling rim, and both side walls are elastically deformed inward. The flange portions are laterally extended to the outer side surfaces of the both side walls, respectively, and a retaining ridge is provided on the lower side of the flange portion at a predetermined distance from the flange. It consists of a long cross-section shape material, below both ends. A plurality of sub-ceiling margins having a notch groove formed on the surface thereof are fitted at their ends to the notch portion of the main ceiling margin, and the notch grooves are notched portions of the main ceiling margin. The upper and lower surfaces of the flange portion of the main ceiling edge are sandwiched between the flange portion of the secondary ceiling edge edge and the retaining projection by engaging the side wall of the U-shaped receiving portion located at Is.

Therefore, according to the present invention, the upper and lower surfaces of the flange portion of the main ceiling field edge are sandwiched between the flange portions and the retaining ridges on both side surfaces of the sub ceiling field edge. It will be locked.

For this reason, rattling does not occur at the edge of the sub-ceiling,
Even if a force to push the sub-ceiling field edge upwards is applied, the protruding protrusion of the sub-ceiling field edge locks on the lower surface of the flange part of the main ceiling field edge. It never comes off.

In particular, according to the present invention, since both side walls of the sub-ceiling field edge having a substantially U-shaped cross section are elastically deformable inward, when the upper end of the side wall of the sub-ceiling field edge is pinched, the side wall bends inward and is U-shaped. The width of the opening at the upper end of the subfield is reduced. For this reason,
The flange of the main ceiling edge does not catch the retaining projection of the secondary ceiling edge, and the retaining protrusion can be pushed down to the bottom surface of the flange, and the secondary ceiling is attached to the notch of the main ceiling margin. It can be easily assembled by dropping or pushing the end of the field edge. As a result, according to the present invention, there is an effect that it is possible to prevent rattling and falling of the sub-ceiling field edge without lowering the workability as compared with the conventional example.
