Description

TECHNICAL FIELD The present invention relates to a ceiling material support structure that uses simple members (support members) and that can be constructed very easily, and a method for constructing the ceiling material support structure.

A roof structure is widely known in which a tight frame is fixed to a horizontal beam (framework) made of a steel frame, and a folded plate is laid on the tight frame.
In such a roof structure, folded plates are laid in a direction perpendicular to the longitudinal direction of the horizontal beams. In addition, since the cross beams are constructed at intervals of 3 to 5 m due to the shape of the roof material, etc., a space is required to install scaffolding inside the room during work such as installing the tight frame and laying the roof material.
In addition, the construction of the ceiling structure in this case is generally performed separately from the construction of the roof structure.
Therefore, if the ceiling is to be constructed in a gymnasium or the like after the construction of the roof, scaffolding or the like is required only for the construction of the ceiling.

For example, Patent Literature 1 proposes a structure in which a vertically long exterior material holding member 4 is fixed to an upper flange 21 of a U-shaped structural member 2 and a decorative material 3 is installed between the structural members 2 , 2 .
Further, Patent Document 2 proposes a structure in which a support for attaching the side edge of the ceiling material and a support for connecting the exterior material are fixed at substantially the same position in a two-story structure.

(a) Front view showing the support member used in the first embodiment, (b) Front view showing the exterior material used, (c) After the step of erecting the support member on the skeleton, the ceiling material is arranged. It is a front view which shows the process which carries out. (a) The front view which shows the ceiling material support structure of 2nd Example of this invention, (b) The front view which shows the used support member, (c) It is the front view which shows the used ceiling material.

The ceiling material support structure of the present invention includes a top part to which the exterior material is directly or indirectly fixed , legs extending downward from the left and right sides and having lower ends fixed to the frame , and at least one of the legs. A support member having a rising portion provided outside the lower end and extending upward ; The mounting portion and the overlapping mounting portion of the ceiling material are engaged with the rising portion of the supporting member .

The support member and the ceiling material in the ceiling material support structure each have the following configurations.
First, the support member has legs extending downward from the left and right of the top to which the exterior material is directly or indirectly fixed, and the lower end of at least one of the legs is fixed to the frame. It has an upwardly extending riser on the outside of the .
In addition, the ceiling material has a structure in which the mounting portion and the overlapping mounting portion whose side ends are raised are engaged with the rising portion of the supporting member. A mounting portion and a mounting overlapping portion formed at the side ends of the ceiling surface portion are configured to be engaged with the rising portion of the support member.

To explain the support member in detail, a conventional product comprising a top portion to which the exterior material is directly or indirectly fixed, and leg portions extending downward from the left and right sides and having the lower ends fixed to the frame is, for example, Many commercial products are provided under names such as Tight Frame.
In contrast to these conventional products, the supporting member in the present invention is different from the commercially available products (conventional products) in that it has a rising portion provided outside the lower end of at least one of the legs and extending upward. Clearly different. Although not particularly limited, the support member may be processed by deforming the strip-shaped steel material in the same manner as the conventional product. In addition, it is preferable that the upper end of the rising portion is provided with a lateral piece-shaped receiving surface portion facing outward or inward.

An auxiliary material may be attached to the top of the support member to directly or indirectly fix the exterior material. For example, as in an embodiment shown in the drawings, which will be described later, a receiving metal fitting may be fixed, and the side edge portion of the exterior member may be elastically fitted (engaged) with the receiving metal fitting. As described above, various forms of receiving metal fittings are conceivable according to the shape of the side edge of the exterior material to be laid.

Moreover, the exterior material is not particularly limited as long as the side edge portions thereof are connected to each other at the top portion of the support member. For example, it is preferable to use a vertical covering material in which both side ends of a flat face plate portion (trough portion) rise in a slanted shape, and adjacent covering materials are connected to form a mountain-like portion, as in the illustrated embodiment described later.

The skeleton to which the lower ends of the legs of the support members are fixed is a horizontal beam in the illustrated embodiment described later, but it is not particularly limited.
Further, in the illustrated embodiment described later, a configuration is adopted in which the side edges of the vertical roofing exterior material are elastically fitted with a bracket fixed to the top, and the side edges are overlapped and crimped to connect. However, it is not particularly limited to this. For example, the connection structure between exterior materials is not particularly limited.

The ceiling material will be described in detail. Assuming that the space between the mounting portion and the overlapping mounting portion is the ceiling surface portion as described above, this ceiling material has the mounting portion at one end of the ceiling surface portion located in the center and the mounting portion at the other end. A mounting overlapping portion is formed in the support member and is disposed so as to engage between the rising portions of the adjacent support members.
The ceiling surface portion forms the ceiling surface when viewed from the inside of the room, and may be flat, corrugated, curved, non-ventilated, or ventilated. In the case of a ventilated ceiling surface portion, a heat insulating material or other functional material may be arranged on the upper surface side, or may not be arranged at all.

If the mounting portion and the overlapping mounting portion of the ceiling material are formed by raising the side ends of the ceiling surface portion and are configured to be attached to the rising portion of the supporting member in an engaging manner, the specific configuration thereof , and may be bilaterally symmetrical or asymmetrical. For example, in the later-described illustrated embodiment, the mounting portion and the overlapping mounting portion are each formed in an inverted L-shape, so that the ceiling material can be attached to the rising portions of the adjacent support members in an engaging manner.
Furthermore, in the later-described illustrated embodiment, by providing a locking piece further outside the mounting portion and the mounting overlapping portion, the mounting portion side is formed into a narrow groove shape (a cross-shaped) that is open at the bottom. Since the overlapped attachment portion is formed in a wide groove shape that opens downward, the attachment portion is completely fitted to the upper end of the rising portion from above, and the overlapped attachment portion is positioned in the left-right direction. It can be installed with a margin while adjusting.
Then, when the mounting portions and the overlapping mounting portions of the adjacent ceiling materials are attached to the rising portion of one support member in an engaged manner, the lower portion is the mounting portion and the upper portion is the mounting portion. In the illustrated embodiment, the mounting portion is positioned on the right side of the ceiling surface portion, and the mounting overlapped portion is positioned on the left side of the ceiling surface portion. I have to.

In addition, the ceiling surface portion is desirably porous (ventilated) in consideration of sound absorption, light weight, etc. For example, it may be formed by processing a material such as punching metal. It may be in any shape, and its specific configuration is not particularly limited. As described above, the ceiling surface portion may not have any heat insulating material or functional material at all. Alternatively, a continuous amorphous heat insulating material may be provided.

The ceiling material support structure of the present invention having these configurations has a configuration in which a strip-shaped narrow support member is arranged between the exterior material and the ceiling material that extend widely in the flow direction, Since the support members and the like used are extremely simple, the practical value is extremely high compared to the above-mentioned conventional examples, and the invention can be applied to various roof structures and ceiling structures.
In addition, since the support member is provided with a rising portion which is provided on the outside of the lower end of at least one of the legs and extends upward, the connection position of the exterior material and the connection position of the ceiling material are aligned. Therefore, each construction can be performed extremely easily.

Furthermore, the construction method of such a ceiling material support structure includes at least one of the top part to which the exterior material is directly or indirectly fixed, the leg part extending downward from the left and right sides and the lower end being fixed to the frame, a support member having a rising portion provided outside the lower end of the leg portion and extending upward; a ceiling member having a ceiling surface portion; is a method for constructing a ceiling material support structure using The method is characterized by performing a step (hereinafter referred to as a second step) of engaging the mounting portion and the mounting overlapping portion of the ceiling material with the rising portion provided on the support member.

The first step is a step in which supporting members are erected at predetermined intervals on a skeleton such as a horizontal beam, and a plurality of supporting members are fixed in advance at positions according to the dimensions of the exterior material and the ceiling material. The fixing means is not particularly limited, and may be welded as in the illustrated embodiment, or may be driven from above by a fixture.
In the second step, the ceiling material is arranged between the left and right adjacent support members, and the ceiling material is arranged so that the mounting portion and the mounting overlapping portion are engaged with the respective rising portions.
Each of these steps can be very easily performed from above. Therefore, there is no need for work such as assembling scaffolding, and the practical value is extremely high.
