Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a ceiling frame member.

[Conventional technology]

FIG. 11 shows a ceiling frame member incorporated in the ceiling portion. The frame member 1 integrally includes a web 3 having a reinforcing portion 2 at its upper end and flanges 4 and 4 projecting from the lower end of the web 3 to both sides. Attached to the lower end and the same frame assembly 1
It is arranged so as to be horizontal and parallel to each other by being bridged between other frame members (not shown) arranged orthogonally to. The flanges 4, 4 of the frame member 1 are configured such that both side edges of the ceiling plate 5 are mounted on the flanges 4, 4 via the upper surfaces 4a, 4a thereof.

[Problems to be solved by the device]

By the way, since the upper surface 4a of each of the flanges 4 is formed as a flat surface, the ceiling plate 5 that rides on the upper surface 4a tends to float, and the interior and the ceiling are not effectively shielded from each other. The appearance was impaired by the appearance of gaps and wavy shapes.

Therefore, in order to prevent the ceiling plate 5 from floating, as shown in FIG. 12, a spring plate type clip 6 is fitted from above the ceiling frame member 1 and the ceiling plates 5 and 5 are attached to the lower end portions 6a and 6a on both sides thereof. Both sides of the clip were pressed from above, but according to this, the clip 6 needs to be attached separately, so that the efficiency of the construction cannot be achieved, and moreover, it is pressed by the spring material. However, the floating of the ceiling plate 5 could not be reliably suppressed.

In view of the above circumstances, the present invention not only improves the efficiency of construction, but also eliminates the floating of the ceiling plate, improves the insulation between the ceiling and the room, and eliminates the appearance defects such as gaps and corrugations. It is an object of the present invention to provide such a ceiling frame member.

[Means for Solving the Problems]

According to this invention, in order to solve the above-mentioned problems, the flange of the ceiling frame member is provided with a projection protruding upward from the upper surface of the flange so that the tip is sharply pointed and pierces the bottom surface of the ceiling plate to be engaged.

[Action]

In this invention, the side portion of the ceiling plate is securely fixed to the flange by the protrusion on the upper surface of the flange, whereby the floating of the side portion is prevented.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment thereof.

1 and 2 show a first embodiment of a ceiling frame member according to the present invention. This ceiling frame member 10 includes a web 12 having a reinforcing portion 11 at the upper end, and the web 12
Is integrally provided with flanges 13 and 13 protruding from the lower end of the both sides. These ceiling frame members 10 ... Are attached to the lower end of the suspending tool 14 extending from above, and the frame members 10 ...
It is arranged so as to be horizontal and parallel to each other by being bridged between other frame members (not shown) arranged orthogonally to each other. The flanges 13 and 13 of the frame member 10 are provided with ceiling plates 15 made of rock wool through the upper surfaces 13a and 13a thereof.
Both sides of the board are designed to ride on.

By the way, on the upper surface 13a of each of the flanges 13, a projection 16 having a mountain-shaped cross-section and having a sharp shape is provided so as to extend continuously in the extending direction of the ceiling frame member 10. The side portions of each ceiling plate 15 to be mounted from above are hammered onto the protrusions 16, and the protrusions 16 are inserted into the bottom face of the ceiling plate 15 by being pierced.

FIG. 3 and FIG. 4 show the second embodiment, and the ceiling frame member 20 of the same embodiment has pin-shaped projections 22 ... The conical sharpened portion 22a is engaged with the ceiling plate 5 to prevent its rising.

5 and 6 show a third embodiment. The ceiling frame member 30 of the embodiment is provided with protrusions 32 ... Formed by a sharp triangular plate on the upper surface 31a of each flange 31. These projections 32 pass through the top surfaces of the ceiling plates 5, 5 and the respective tip portions 32a are bent on the top surfaces, whereby the floating of the ceiling plates 5 is prevented.

7 and 8 show the fourth embodiment. The ceiling frame member 40 of the embodiment has thin needle-like protrusions 42 on the upper surface 41a of each flange 41, penetrates the ceiling plate 5 to the upper surface, and bends it at a right angle to the upper surface of the ceiling plate 5. It is designed to be used. Each of the protrusions 42 is bent over a washer 43 provided on each upper surface of the ceiling plate 5 through the protrusion 42, and the washer 43 prevents the protrusion 42 from biting into the ceiling plate 5. ing.

FIG. 9 shows a fifth embodiment. In the ceiling frame member 50 of the embodiment, upward protrusions 52 are arranged on both sides of each flange 51. As described later, the ceiling frame member 50 has a U-shaped base portion 54 in which a groove is directed downward in a cross section between the web 53 and the flange 51, and the base portion 54 is on the indoor side. From the viewpoint, it is designed so that it looks like a joint with a certain width and depth.

As described above, in the ceiling frame member according to the present invention, since the flange is provided with the projection with which the ceiling plate is engaged, the side portion of the ceiling plate is securely fixed to the flange by the projection on the upper surface of the flange. Attached, the floating of the same side part is reliably prevented by simple construction.

In addition, FIG. 13 shows that a conventional inverted T-shaped ceiling frame member 60 is used, and flanges 61, 61 on both sides thereof are provided with a groove 63,
It shows that the ceiling plate 62 is supported by inserting the 63. Since this one is designed so that the grooves 63, 63 are inserted into the flanges 61, 61, the workability is poor, and moreover, the ceiling plate 62 is designed so that only the upper portion of the groove 63 is placed on the flange 61. , Was weak in strength. Between the adjacent ceiling boards 62, 62, the bottom of the ceiling frame member 60 and the groove 64 formed by both ceiling boards 62, 62 can be seen from the indoor side, but since this groove 64 is shallow, it was not possible to get a sense of depth. . Therefore, Fig. 10 (Fig. 9)
As shown in (including the figure), the ceiling frame material was modified.
That is, in the embodiment shown in FIG. 10, the protrusion 73 is provided on the upper surface of the flange 72 in order to enhance the coupling force with the ceiling plate 5. As a result, the ceiling plate 5 can be simply placed from above, which improves the workability. Moreover, since the ceiling plate is designed to have all of its thick portion placed on the flange, both sides of the ceiling plate can be mounted. The connection part which is is stronger in strength. A groove at the base can be seen from the inside of the room between adjacent ceiling boards. Since this groove has a width and a depth, a feeling of depth can be obtained when viewed from the inside of the room.

[Effect of device]

Since the ceiling frame member according to the present invention is configured as described above, the side portion of the ceiling plate is securely fixed to the projection on the upper surface of the flange by a simple construction, and the floating portion of the side portion is prevented. As a result, the interior of the ceiling and the ceiling are effectively shielded from each other, and since they do not float up, there is no visible gap or wavy state.
