DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention places a step formed on the lower peripheral edge of a ceiling plate on a lower flange portion of a ceiling edge having a substantially inverted T-shaped cross section. , It is related to the upper rail mounting structure of the partition wall to the so-called system ceiling, which is positioned and the appearance of the bottom joint is revealed.

(Problems to be solved by conventional technology and device) Conventionally, in a ceiling of a building or the like, due to the necessity of inspecting the ceiling and maintenance of equipment, as shown in FIG. 6 and FIG. The lower flange portion 2 of the ceiling field 1 is placed and positioned on the lower flange portion 2 of the ceiling field 1 having a shape by placing and positioning a step 4 formed on the peripheral edge of the lower surface of the ceiling plate 3 by a notch or the like. There is provided a ceiling structure in which the dents are exposed by denting them from the joints of the ceiling surface to a bottom joint shape, and a regular array pattern of the ceiling boards 3 and a solid feeling due to the thickness of the ceiling boards 3 are expressed.

However, in the system ceiling having the structure in which the bottom joint-like ceiling appearance is exposed as described above, when the space is divided into small compartments for each office by partition wall panels, for example,
When the upper rail 5 having a substantially U-shaped cross section is directly attached to the lower flange portion 2 of the ceiling rim 1 with screws or the like, the lowermost surface 2a of the lower flange portion 2 is dented from the lower surface 3a of the ceiling plate 3. (FIG. 6) There is a problem that a gap 4a is generated between the lower flange portion 2 and the upper rail 5 to deteriorate the airtightness and reduce the soundproofness and the air conditioning efficiency.

Therefore, as shown in FIG. 8, when the upper rail 6 of the partition wall 7 is attached to the system ceiling, the adjustment plate 8 such as a metal plate is interposed to prevent the generation of the gap. In order to prevent the soundproofness and the air-conditioning efficiency from deteriorating as the number of points increases, the adjusting plate 8 is attached to the ceiling edge 1
There is a problem in that it is troublesome to construct since it has to be provided without a gap over the entire length of the lower surface of the.

In view of the above problems, an object of the present invention is to provide an upper rail mounting structure for a partition wall, which has excellent airtightness and is easy to install while making use of the bottom joint appearance of the ceiling surface.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention provides a lower peripheral edge of a ceiling plate at a lower flange portion of a ceiling field edge having a substantially inverted T-shaped cross-section suspended from a ceiling base material. A ceiling wall is formed by placing a step provided on the ceiling wall, and an upper rail of the partition wall is attached along the lower surface of the lower flange portion of the ceiling field edge. The lower flange portion has a cross-section substantially inverted hat shape having a ridge portion along the longitudinal direction at the center of the lower surface, and the lower end surface of the ridge portion is positioned on substantially the same plane as the lower surface of the ceiling plate in the mounted state. The upper rail of the partition wall is attached to the lower end surface of the ridge portion.

(Effect) Therefore, according to the present invention, since the ridge is integrally formed in the center of the lower surface of the lower flange of the ceiling edge, no gap is formed between the upper rail of the partition wall. ,
Airtightness is obtained in the upper part of the partition wall, and the ceiling surface (lower surface of the ceiling plate) and the lower surface of the protruding strip are located on substantially the same plane, so that the protruding strip interferes with the installation of ceiling equipment. Never be.

(Embodiment) An embodiment of the upper rail mounting structure of the partition wall according to the present invention will be described below with reference to the accompanying drawings.

As the partition wall mounting structure according to the first embodiment, as shown in FIGS. 1 to 4, the ceiling field edge 10 is hung from a ceiling base (not shown), and the ceiling board 20 is placed on it. A partition wall 30 is attached.

That is, the ceiling rim 10 is integrally provided with a hanging portion 11 having a substantially H-shaped cross section at the upper end portion of a vertical web material,
A lower flange portion 12 having a substantially inverted cross section formed by integrally molding a ridge portion 13 formed by a substantially U-shaped bulge portion along the longitudinal direction on the lower surface of the central portion is provided at the lower end portion. The height dimension of the lower flange portion 12 including the ridge portion 13 is substantially the same as the depth dimension of the step portion 21 of the ceiling plate 20 described later.
When the peripheral edge portion of the ceiling plate 20 is placed on the top 12, the lower surface of the ceiling plate 20 and the lower end surface 13a of the protrusion 13 are located on substantially the same plane.

A plurality of ceiling rims 10 are suspended in parallel from a ceiling substrate (not shown) and arranged side by side, and between the ceiling rims 10 and 10, and between the ceiling rim 10 and the rim 14 attached to the wall surface A. A sub-ceiling edge 15 is laid between the two to form a lattice-shaped ceiling frame.

The ceiling plate 20 is made of a rock wool sound absorbing plate or the like, and is formed by cutting out the peripheral edge of the lower surface to form a step portion 21 having a depth dimension of about 1/2 of the plate thickness dimension. It is placed on the lower flange portion 12 of the field edge 10, and at the terminal end of the ceiling surface, the lower surface edge is placed on the peripheral edge 14 to form the ceiling surface (first
Figure). As a result, the grid-like bottom joints formed by the notched step portions 21 and the lower flange portions 12 of each ceiling plate 20 appear on the ceiling surface as two parallel grooves, and the lower surface 22 of the ceiling plate 20 is exposed.
And the lower end surface 13a of the ridge portion 13 provided on the lower flange portion 12 are located on substantially the same plane, and a narrow groove is formed on both sides of the ridge portion 13.
16 is what appears.

The upper end of the partition wall 30 is held / fixed by an upper rail 32 having a substantially U-shaped cross section which is attached to the lower end surface 13a of the ridge 13 provided on the lower flange 12 with a tapping screw 31 and opens downward. It is what is done. That is, the partition wall 30 locks the upper fitting portion 33 provided at the upper end portion to the upper rail 32, and mounts the lower fitting portion 34 provided at the lower end portion on the lower rail 17 fixed to the floor base B. And is standing upright.

In the present embodiment, since the upper surface of the upper rail 32 is in direct contact with the lower end surface 13a of the ridge 13 provided on the lower flange portion 12 of the ceiling field edge 10 and closes the space between the upper rail 32 and the upper surface, As described above, no gap is created at the upper end portion of the partition wall 30, and soundproofness and air conditioning efficiency are not reduced.

In addition, the ridge portion 13 of the lower flange portion 12 of the ceiling field edge 10 is not limited to the above-described substantially U-shaped bulging shape.
As shown in FIG. 5, it goes without saying that a solid bar-shaped protrusion 13 may be integrally formed on the lower surface of the lower flange 12 (second embodiment).

(Effect of the Invention) As is apparent from the above description, according to the present invention, the appearance of the bottom joint is shown on the ceiling surface, and the lower end surface of the ridge provided at the center of the lower flange portion of the ceiling edge is Since it is located on the same plane as the lower surface of the ceiling plate, when the upper rail of the partition wall is attached, the lower rail of the ridge provided at the center of the lower surface of the lower flange of the ceiling edge and the upper rail Will come into direct contact with the upper surface of. Therefore, no gap is formed between the upper rail of the partition wall and the ceiling edge of the system ceiling, so that the airtightness of the partition wall can be improved while utilizing the appearance of the bottom joint of the ceiling surface.

Further, unlike the conventional example, since it is not necessary to interpose an adjusting plate between the ceiling edge and the upper rail of the partition wall, not only the number of parts is reduced, but also the work is easy and the workability is low. improves.

Furthermore, since the ridges are integrally provided on the lower surface of the lower flange along the longitudinal direction, the upper rail can be screwed directly without interposing an adjusting plate, and the upper wall of the partition wall can be fixed with screws. This has the effect of increasing the force of attachment.
