Description

[Technical Field]

[0001] The present invention relates to a sill mounting member and a suspended ceiling structure. [Background technology]

[0002] A conventional suspended ceiling structure is known that is composed of hanging bolts hanging from a structural frame such as an upper floor floor slab, rafters supported by the hanging bolts, rafters attached to the rafters so as to cross the rafters, and ceiling panels fixed to or placed on the rafters. In this case, the rafters and rafters are usually positioned perpendicular to each other via rafter attachment members (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-031178 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with this conventional technology, the soffits and soffit supports are attached so that they intersect at right angles. Therefore, if the wall of a building on which a suspended ceiling is to be installed is designed to be curved or bent in a plan view, in order to make the soffit support perpendicular to the soffit extending toward the wall, it is necessary to divide the soffit support into short sections and arrange the soffit support in a stepped manner, which increases the total length of the soffit support.In addition, since the soffit support needs to be processed for each short section, there is an issue that the labor required for installation work increases.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a siding mounting member that allows siding supports to be positioned to match the shape of the wall surface, even in buildings where the wall surface is curved or bent in plan view, and a suspended ceiling structure using the same. [Means for solving the problem]

[0006] In order to achieve the above object, the following configuration is realized. (1) A first aspect of the present invention is a siding mounting member used in a suspended ceiling structure, characterized in that it comprises a main body portion attached to a siding support that constitutes the suspended ceiling structure, and a support portion that is connected to the lower part of the main body portion so that the angle can be freely adjusted and that is attached to the siding that constitutes the suspended ceiling structure. (2) In the configuration of (1) above, the main body portion comprises an upright portion, an upper surface portion that bends and extends from the upper end of the upright portion, a front surface portion that extends downward from the tip of the upper surface portion, and a base surface portion that extends from the lower end of the upright portion to the opposite side of the upper surface portion, and the upper surface portion and the front surface portion engage with the stile support, and the base surface portion is connected to the support portion so that the angle can be freely adjusted. (3) In the configuration of (1) or (2) above, the support portion comprises an upper surface portion, a first side surface portion hanging down from a first side end of the upper surface portion and extending to a first side, a second side surface 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 surface portion and the second side surface portion being 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 siding support, a siding attached to the siding support, and a siding mounting member described in any one of (1) to (3) that can be attached so that the angle between the siding support and the siding can be freely adjusted in a plan view. (5) In the configuration of (4) above, when the soffit support is placed closest to the wall surface of the building, it is placed so as to correspond to the shape of the wall surface in a plan view. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a siding mounting member that allows siding supports to be positioned to match the shape of the wall surface, even in buildings where the wall surface is curved or bent in a plan view, and a suspended ceiling structure using the same.

DETAILED DESCRIPTION OF THE INVENTION

[0009] (Embodiment) DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the same elements are designated by the same reference numerals throughout the description of the embodiments.

[0010] (Suspended ceiling structure) First, the suspended ceiling structure 1 will be described with reference to Figure 1. Figure 1 is a plan view illustrating the overall layout of the suspended ceiling structure 1. To briefly touch on the configuration of the suspended ceiling structure 1 when viewed three-dimensionally, the suspended ceiling structure 1 is made up of suspension bolts (not shown) hanging down from a structural frame such as an upper floor floor slab, joist supports 30 suspended and supported by the suspension bolts, joist supports 40 attached so as to intersect with the joist supports 30, and ceiling panels (not shown) fixed to or placed on the joist supports 40.

[0011] Now, in buildings that have suspended ceilings, such as halls, museums, conference rooms, swimming pools, and other public buildings, the walls are often designed to be curved or bent 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 joist supports 30, 30A and joist 40 are arranged in a plan view as follows, for example:

[0012] 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, like the soffit support 30 (shown in solid lines) that extends horizontally in a straight line as shown in the bottom of the figure.The next soffit support 30A to be installed on the wall B side is, for example, like 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 top 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 number of construction steps.

[0013] Therefore, in this embodiment, as shown in Figure 1, a joist support 30 (shown by a solid line) is arranged to correspond to and follow the shape of the wall surface B. Specifically, the suspended ceiling structure 1 is composed of the joist support 30, a joist 40 attached to the joist support 30, and a joist mounting member 50 (described later) that can be attached so that the angle between the joist support 30 and the joist 40 can be adjusted freely in a plan view. When the joist support 30 is arranged closest to the wall surface B of the building, it is arranged to correspond to the shape of the wall surface B in a plan view.

[0014] (Rafter mounting components) Next, the siding mounting member 50 will be described with reference to Figure 2 onwards. Figures 2 and 3 show the mounting of the siding support 30 and the siding 40 using the siding mounting member 50 according to this embodiment, with Figure 2 being a perspective view from diagonally above and Figure 3 being a perspective view from above the front. The siding mounting member 50 is what is called a "clip" or similar in the art.

[0015] Although more detail will be provided later, the joist mounting member 50 comprises a main body 51 that is attached to the joist 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 joist 40 that constitutes the suspended ceiling structure 1. The main body 51 and the support part 52 are fastened together with bolts 53.

[0016] 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.

[0017] The main body 51 of the siding mounting member 50 engages with the siding support 30 so as to straddle its outside, and is fixed with screws to the side of the siding support 30 when installation is complete. The support portion 52 is positioned so as to be in close contact with the inside of both side surfaces 41, 42 of the siding 40, and is fixed with screws to both side surfaces 41, 42 when installation is complete. The bottom of the support portion 52 may or may not contact the bottom surface 43 of the siding 40.

[0018] The main body 51 and the support part 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 to each other. The soffit mounting member 50 will be described in detail below.

[0019] Figure 4 shows an oblique view of the entire sill mounting member 50 from above and in front, Figure 5 shows the main body 51 from the front, Figure 6 shows the main body 51 from above, Figure 7 shows the main body from a side, and Figure 8 shows the support part from an oblique view from above.

[0020] 4 to 7, the main body 51 includes an upright portion 51c, an upper surface portion 51b that bends and extends from the upper end of the upright portion 51c, a front surface portion 51a that extends downward from the tip of the upper surface portion 51b, and a base surface portion 51d that extends from the lower end of the upright portion 51c to the opposite side from the upper surface portion 51b. The upper surface portion 51b and the front surface portion 51a engage with the soffit support 30, and the base surface portion 51d is connected to the support portion 52 so that its angle can be freely adjusted.

[0021] A screw hole 51e is provided at approximately the center of the elevation portion 51c for screwing the main body portion 51 to the siding support 30. A bolt hole 51f is provided at the center of the tip end of the base portion 51d for bolting the main body portion 51 to the support portion 52 with a bolt 53 so that the angle can be freely adjusted.

[0022] 5, the main body 51 has dimensions required for engaging with the siding support 30 at the upper surface 51b and the upper part of the vertical surface 51c, while the width (in the direction along the siding support 30) is narrowed at the lower part of the vertical surface 51c close to the base surface 51d. This is to prevent the main body 51 from interfering with both side surfaces 41, 42 of the siding 40, even if the main body 51 is positioned at an acute angle relative to the support 52, and therefore at an acute angle relative to the siding 40, because the main body 51 is connected to the support 52 so that the angle can be freely adjusted.

[0023] 6, the base surface 51d of the main body 51 has a triangular shape with rounded corners at the tip. This is also to prevent the main body 51 from interfering with the side surfaces 41, 42 of the joist 40, even if the main body 51 is positioned at an acute angle relative to the support 52, and therefore at an acute angle relative to the joist 40, because the main body 51 is connected to the support 52 so that the angle can be freely adjusted.

[0024] 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 (longitudinal) side end 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 (longitudinal) side end 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 of the (transverse) front end of the upper surface portion 52a, and a rear surface portion 52e that hangs down from a second side end of the (transverse) rear end of the upper surface portion 52a. The upper surface portion 52a is connected to the main body portion 51 so that its angle can be adjusted freely, 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 siding 40.

[0025] A bolt hole 52f is provided in the center of the top surface portion 52a for bolt-fixing the support portion 52 to the main body portion 51 with a bolt 53 so that the angle can be freely adjusted. Furthermore, a screw hole 52g is provided in the approximate center of the first side surface portion 52b for screw-fixing to the side surface 41 of the joist 40, and a screw hole 52h is provided in the approximate center of the second side surface portion 52c for screw-fixing to the side surface 42 of the joist 40.

[0026] 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 joist 40. The support portion 52 has a shape that is point-symmetrical about the bolt hole 52f, and by rotating the support portion 52 clockwise inside the joist 40, the first side surface portion 52b and the second side surface portion 52c can be brought into close contact with the insides of both side surfaces 41, 42 of the joist 40.

[0027] 9 to 11, the procedure for connecting the main body 51 and support part 52 of the soffit mounting member 50 so that the angle can be adjusted freely, and thus for attaching the soffit support 30 and soffit 40 so that the angle can be adjusted freely, will be described.

[0028] First, the main body 51 of the siding mounting member 50 is engaged with the siding support 30, and the support portion 52 is positioned inside the siding 40. Then, as shown in Fig. 9, the siding support 30 and the siding 40 are fastened and connected with bolts 53 via bolt holes 51f provided in the base surface portion 51d of the main body 51 and bolt holes 52f provided in the upper surface portion 52a of the support portion 52 so that the siding support 30 and the siding 40 intersect at the desired angle θ.

[0029] Next, as shown in FIG. 10, the main body 51 is fixed to the side surface of the siding support 30 with screws through the screw holes 51e provided in the upright surface portion 51c.

[0030] Finally, as shown in FIG. 11, the support portion 52 is fixed to both side surfaces 41, 42 of the siding 40 with screws via the screw holes 52g provided in the first side surface portion 52b and the screw holes 52h provided in the second side surface portion 52c.

[0031] (Effects of the embodiment) The joist mounting member 50 used in the suspended ceiling structure 1 according to this embodiment comprises a main body 51 attached to the joist support 30 that constitutes the suspended ceiling structure 1, and a support portion 52 connected to the lower portion of the main body 51 in an angle-adjustable manner and attached to the joist 40 that constitutes the suspended ceiling structure 1, making it possible to attach the joist support 30 and the joist 40 at an adjustable angle. The suspended ceiling structure 1 comprises the joist support 30, the joist 40 attached to the joist support 30, and the joist mounting member 50 that can attach the joist support 30 and the joist 40 so that the angle is adjustable in a plan view, so that the joist support 30 can be positioned to match the shape of the wall B, even in a building where the wall B is bent or curved in a plan view.

[0032] Although the embodiments have been described above, the present invention is not limited to the specific embodiments and includes various modifications, which will be apparent to those skilled in the art from the description of the claims. [Explanation of symbols]
