Description

The present invention relates to a siding mounting member and a suspended ceiling structure.

Conventionally, a suspended ceiling structure is known that is composed of hanging bolts hanging from a structural frame such as an upper floor floor slab, a soffit support suspended by the hanging bolts, a soffit attached to the soffit support so as to cross the soffit support, and a ceiling plate fixed to or placed on the soffit. In this case, the soffit support and the soffit are usually arranged so as to be perpendicular to each other via a soffit attachment member (see Patent Document 1).

JP 2018-031178 A

However, with this conventional technology, the siding and the siding support are attached so that they intersect at right angles. In cases where the wall of a building on which a suspended ceiling is to be installed is designed to be curved or bent in plan view, attempting to make the siding support perpendicular to the siding extending toward the wall requires dividing the siding support into short sections and arranging the siding support in a stepped manner, which increases the total length of the siding support. In addition, the siding support needs to be processed for each short section, which increases the labor required for installation work.

The present invention was made in consideration of the above circumstances, and aims to provide a siding mounting member and a suspended ceiling structure using the same that allows siding supports to be positioned to match the shape of the wall, even in buildings where the wall is bent or curved in plan view.

In order to achieve the above object, the following configuration is realized.
(1) A first aspect of the present invention is a soffit mounting member for use in a suspended ceiling structure, characterized in that it comprises a main body portion that is attached to a soffit support that constitutes the suspended ceiling structure, and a support portion that is connected below the main body portion so that the angle can be freely adjusted and is attached to the soffit that constitutes the suspended ceiling structure.
(2) In the above configuration (1), the main body portion comprises a vertical portion, an upper surface portion extending in a bent manner from the upper end of the vertical portion, a front surface portion extending downward from the tip of the upper surface portion, and a base surface portion extending from the lower end of the vertical portion to the opposite side to the upper surface portion, the upper surface portion and the front surface portion engaging with the sill support, and the base surface portion being connected to the support portion so that the angle can be freely adjusted.
(3) In the above configuration (1) or (2), the support portion comprises an upper surface portion, a first side portion hanging down from a first side end of the upper surface portion and extending to a first side, a second side portion hanging down from a second side end of the upper surface portion and extending to a second side, a front surface portion hanging down from the first side end side of the front end of the upper surface portion, and a rear surface portion hanging down from the second side end side of the rear end of the upper surface portion, the upper surface portion being connected to the main body portion so that the angle can be freely adjusted, and the first side portion and the second side portion are in close contact with the inside of both side surfaces of the sill.
(4) A second aspect of the present invention is a suspended ceiling structure comprising a soffit support, a soffit attached to the soffit support, and a soffit mounting member described in any one of (1) to (3) that can be attached so that the angle between the soffit support and the soffit can be freely adjusted in a plan view.
(5) In the configuration of (4) above, when the sill support is placed closest to the wall of a building, it is placed so as to correspond to the shape of the wall in a plan view.

The present invention provides a siding mounting member that allows siding supports to be positioned to match the shape of the wall, even in buildings where the wall is bent or curved in plan view, and a suspended ceiling structure using the same.

(Embodiment)
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the following, like elements are designated by like reference numerals throughout the description of the preferred embodiments.

(Suspended ceiling structure)
First, the suspended ceiling structure 1 will be described with reference to Fig. 1. Fig. 1 is a diagram illustrating the overall layout of the suspended ceiling structure 1 in a plan view. In addition, to touch on the configuration of the suspended ceiling structure 1 when viewed three-dimensionally, the suspended ceiling structure 1 is composed of hanging bolts (not shown) hanging from a structural body such as an upper floor floor slab, a joist support 30 suspended and supported by the hanging bolts, a joist 40 attached to the joist support 30 so as to intersect with the joist support 30, and a ceiling board (not shown) fixed to or placed on the joist 40.

Now, in buildings with suspended ceilings, such as buildings for public use such as halls, museums, conference rooms, and swimming pools, the walls are often designed to be curved or curved rather than straight, due to the design of the building itself. Figure 1 shows an example of a building where wall B is curved, and in the prior art, the soffit supports 30, 30A and soffit 40 are arranged in plan view as follows, for example.

That is, the last soffit support 30 that can be arranged in a straight line perpendicular to the soffit 40 extending toward wall B is, for example, the soffit support 30 (shown in solid lines) that extends horizontally in a straight line as shown in the lower part of the figure. The next soffit support 30A on the wall B side is, for example, the soffit support 30A (shown in dashed lines) that is divided horizontally into short sections and extends in a stepped manner as shown in the upper part of the figure. However, as mentioned above, this means that the soffit support 30A is installed in short sections in a stepped manner, which increases the total length of the soffit support 30A and increases the amount of work required for construction.

In this embodiment, as shown in Figure 1, the siding support 30 (shown in solid lines) is positioned to correspond to and follow the shape of the wall surface B. Specifically, the suspended ceiling structure 1 is composed of the siding support 30, the siding 40 attached to the siding support 30, and the siding attachment member 50 (described below) that allows the siding support 30 and the siding 40 to be attached so that the angle can be freely adjusted in a plan view. When the siding support 30 is placed closest to the wall surface B of the building, it is positioned to correspond to the shape of the wall surface B in a plan view.

(Ribbed mounting components)
Next, the furring strip mounting member 50 will be described with reference to Fig. 2 and subsequent figures. Fig. 2 and Fig. 3 show the mounting of the furring strip support 30 and the furring strip 40 by the furring strip mounting member 50 according to this embodiment, with Fig. 2 being a perspective view seen from diagonally above, and Fig. 3 being a perspective view seen from above the front. The furring strip mounting member 50 is what is referred to as a "clip" or the like in the art.

Although more details will be described later, the soffit mounting member 50 comprises a main body 51 that is attached to the soffit support 30 that constitutes the suspended ceiling structure 1, and a support part 52 that is connected to the lower part of the main body 51 so that the angle can be freely adjusted and that is attached to the soffit 40 that constitutes the suspended ceiling structure 1. The main body 51 and the support part 52 are fastened together by a bolt 53.

Here, we will explain the case where a so-called C-bar with a C-shaped cross section is used as the furring strip support 30, and a UL stud with a concave cross section is used as the furring strip 40, but this embodiment is not limited to these shapes.

The main body 51 of the furring strip mounting member 50 engages the furring strip support 30 so as to straddle its outer side, and is fixed to the side of the furring strip support 30 with screws when installation is complete. The support part 52 is positioned so as to be in close contact with the inside of both sides 41, 42 of the furring strip 40, and is fixed to both sides 41, 42 with screws when installation is complete. The bottom of the support part 52 is in contact or not in contact with the bottom surface 43 of the furring strip 40.

The main body 51 and the support 52 are fastened by bolts 53 so that the soffit support 30 and the soffit 40 intersect at a desired angle, including when they are perpendicular. The details of the soffit mounting member 50 are described below.

Figure 4 shows the entire furring strip mounting member 50 as viewed from above and in front, Figure 5 shows the main body 51 as viewed from the front, Figure 6 shows the main body 51 as viewed from above, Figure 7 shows the main body as viewed from the side, and Figure 8 shows the support part as viewed from diagonally above.

As shown in Figures 4 to 7, the main body 51 has a vertical surface 51c, an upper surface 51b that bends and extends from the upper end of the vertical surface 51c, a front surface 51a that extends downward from the tip of the upper surface 51b, and a base surface 51d that extends from the lower end of the vertical surface 51c to the opposite side to the upper surface 51b. The upper surface 51b and the front surface 51a engage with the siding support 30, and the base surface 51d is connected to the support 52 so that the angle can be freely adjusted.

A screw hole 51e is provided at approximately the center of the vertical surface portion 51c for fixing the main body portion 51 to the siding support 30 with a screw. In addition, a bolt hole 51f is provided at the center of the tip side of the base surface portion 51d for fixing the main body portion 51 to the support portion 52 with a bolt 53 so that the angle can be freely adjusted.

5, the main body 51 has the dimensions required for engaging with the soffit support 30 at the upper surface 51b and the upper part of the vertical surface 51c, while the width (in the direction along the soffit support 30) is narrowed at the lower part of the vertical surface 51c close to the base surface 51d. This is because the main body 51 is connected to the support 52 so that the angle can be freely adjusted, so that even if the main body 51 is positioned at an acute angle to the support 52, and therefore at an acute angle to the soffit 40, the main body 51 does not interfere with both side surfaces 41, 42 of the soffit 40.

6, the base surface 51d of the main body 51 has a triangular shape with rounded corners at the tip. This is to prevent the main body 51 from interfering with the side surfaces 41, 42 of the siding 40 even if the main body 51 is positioned at an acute angle to the support 52, and therefore at an acute angle to the siding 40, because the main body 51 is connected to the support 52 so that the angle can be freely adjusted.

4 and 8, the support portion 52 includes an upper surface portion 52a, a first side surface portion 52b that hangs down from a first side end (in the longitudinal direction) of the upper surface portion 52a and extends to a first side (toward the front end), a second side surface portion 52c that hangs down from a second side end (in the longitudinal direction) of the upper surface portion 52a and extends to a second side (toward the rear end), a front surface portion 52d that hangs down from a first side end side of the front end (in the transverse direction) of the upper surface portion 52a, and a rear surface portion 52e that hangs down from a second side end side of the rear end (in the transverse direction) of the upper surface portion 52a. The upper surface portion 52a is connected to the main body portion 51 so that the angle can be freely adjusted, and the first side surface portion 52b and the second side surface portion 52c are in close contact with the insides of both side surfaces 41, 42 of the sill 40.

A bolt hole 52f is provided in the center of the upper surface portion 52a for bolting the support portion 52 to the main body portion 51 with a bolt 53 so that the angle can be freely adjusted. In addition, a screw hole 52g is provided in approximately the center of the first side surface portion 52b for screwing to the side surface 41 of the joist 40, and a screw hole 52h is provided in approximately the center of the second side surface portion 52c for screwing to the side surface 42 of the joist 40.

The upper surface portion 52a has dimensions such that the first side surface portion 52b and the second side surface portion 52c are in close contact with both side surfaces 41, 42 of the furring strip 40. The support portion 52 has a shape that is point-symmetrical with respect to the bolt hole 52f, and the first side surface portion 52b and the second side surface portion 52c can be brought into close contact with the inside of both side surfaces 41, 42 of the furring strip 40 by rotating the support portion 52 clockwise inside the furring strip 40.

With reference to Figures 9 to 11, the procedure for connecting the body part 51 and the support part 52 of the furring strip mounting member 50 so that the angle can be freely adjusted, and thus attaching the furring strip support 30 and the furring strip 40 so that the angle can be freely adjusted, will be described.

First, the main body 51 of the siding mounting member 50 is engaged with the siding support 30, and the support part 52 is placed inside the siding 40. Then, as shown in FIG. 9, the siding support 30 and the siding 40 are connected by fastening them with bolts 53 via the bolt holes 51f provided in the base surface part 51d of the main body 51 and the bolt holes 52f provided in the upper surface part 52a of the support part 52 so that they intersect at the desired angle θ.

Next, as shown in FIG. 10, the main body 51 is fixed to the side of the siding support 30 with screws through the screw holes 51e provided in the vertical surface portion 51c.

Finally, as shown in FIG. 11, the support portion 52 is fixed to both sides 41, 42 of the siding 40 with screws via the screw holes 52g in the first side portion 52b and the screw holes 52h in the second side portion 52c.
