Description

The present invention relates to a ceiling structure in which the members (ceiling material and holding member) used are simple and the construction can be performed extremely easily, and a construction method thereof.

A roof structure in which a tight frame is fixed to a cross beam (framework) made of a steel frame and a folded plate is laid on the tight frame is widely known.
In such a roof structure, folded plates are laid in a direction orthogonal to the longitudinal direction of the cross beam. In addition, since the cross beams are constructed at intervals of 3 to 5 m depending on the shape of the roofing material, space is required to install scaffolding on the indoor side during work such as mounting a tight frame and laying the roofing material.
Further, the ceiling structure in this case is generally performed separately from the construction of the roof structure.
Therefore, when attempting to perform ceiling construction in a gymnasium or the like after the roof construction, scaffolding or the like was required only for the ceiling construction.

For example, Patent Document 1 proposes a structure in which a wall material such as a ceiling material is erected between C-shaped steels (grooved steels with lips).
Further, Patent Document 2 proposes a structure in which a ceiling folded plate body and a folded plate roof body are laid on a beam.

However, in Patent Document 1, the wall material used is a dedicated material for the ceiling, and it is difficult to use it other than the ceiling material. Specifically, of the left and right end edges of the face plate portion, one mounting portion is mounted so as to cover the C-shaped steel, but the other mounting portion is mounted on the lip of the lower flange of the C-shaped steel. , It was a configuration that could not form a continuous exterior surface.
Further, in the above-mentioned Patent Document 2, it is not proposed that the ceiling folded plate body and the folded plate roof body having different shapes are laid in the same manner as the interior and exterior.
As described above, since the above-mentioned Patent Documents 1 and 2 cannot be used for both the roof structure and the ceiling structure, there are various problems such as the above-mentioned product management.

Therefore, an object of the present invention is to propose a ceiling structure in which the members (ceiling material and holding member) used are simple and the construction can be performed extremely easily, and a construction method thereof.

In the present invention, the rising portion is raised upward on the left and right sides of the face plate portion and has an engaging portion near the base end, the supporting surface portion extending outward from the upper end of the rising portion, and the tip of the supporting surface portion is folded. The ceiling structure is composed of a ceiling material provided with a lowered folding portion and a holding member provided with a horizontal support base portion, and the support surface portions of the ceiling material adjacent to each other on the left and right support the holding member. It relates to a ceiling structure characterized by being connected in a polymerized manner on a pedestal.

The present invention also proposes a ceiling structure characterized in that, in the ceiling structure, the engaging portion of the ceiling material is formed so as to project toward the face plate portion.

The present invention also proposes a ceiling structure in which the face plate portion of the ceiling material is porous in the ceiling structure.

The present invention also proposes a ceiling structure characterized in that a decorative material or a hanging metal fitting is attached between the engaging portions of the ceiling materials adjacent to each other on the left and right sides of the ceiling structure.

Further, the present invention is a method of constructing the ceiling structure, in which the lower ends of the legs are fixed to the base from the roof side and the holding member is erected, and then left and right from the roof side. It also proposes a method for constructing a ceiling structure, characterized in that the support surface portion provided on the ceiling material adjacent to the ceiling member is connected in a polymerized manner on the support base portion of the holding member. Is.

In the ceiling structure of the present invention, the ceiling material is also extremely simple, and the ceiling materials adjacent to the left and right can be easily connected by a simple holding member provided with a horizontal support base portion, and the ceiling surface can be easily connected. Construction can be done.

Further, when the engaging portion of the ceiling material is formed so as to project toward the face plate portion side, the construction can be performed extremely easily while pressing the engaging portion from the face plate portion side toward the holding member.

Further, when the face plate portion of the ceiling material is porous, the portion (ceiling surface portion) can be formed by, for example, punching metal, and even if a heat insulating material or a functional material is arranged, it is not arranged. It may be good, but sound absorption and light weight are taken into consideration.

In addition, if decorative material or hanging metal fittings are attached between the engaging parts of the ceiling materials adjacent to the left and right, the joints between the ceiling materials can be hidden from the indoor side with the decorative material, or used as an installation location for lighting equipment, etc. Can be done.

Further, in the construction method of the ceiling structure of the present invention, after the step of erection of the holding member on the base is performed, the step of arranging the ceiling material between the holding members adjacent to the left and right is performed.

The ceiling structure of the present invention has a rising portion that is raised upward on the left and right sides of the face plate portion and has an engaging portion near the base end, a support surface portion that extends outward from the upper end of the rising portion, and a support surface portion. It consists of a ceiling material having a folded portion whose tip is folded down, and a holding member having a horizontal support base portion, and the support surface portions of the ceiling material adjacent to each other on the left and right are on the support base portion of the holding member. It is characterized in that it is connected in a polymerized manner.

As described above, the ceiling material includes a face plate portion, a rising portion that is raised upward on the left and right sides thereof and has an engaging portion near the base end, and a support surface portion that extends outward from the upper end of the rising portion. And a folded-down portion in which the tip of the support surface portion is folded down. Then, the ceiling surface can be formed by connecting the support surface portions of the ceiling material adjacent to the left and right on the horizontal support base portion provided on the holding member in a polymerized manner.
The "outside" refers to a direction away from the face plate portion, and therefore, a support surface portion is provided so as to extend further to the left from the upper end of the rising portion formed on the left side of the face plate portion. A support surface portion is provided so as to extend further to the right side from the upper end of the rising portion formed on the right side of the face plate portion.

The face plate portion is a portion that forms a ceiling surface, and may be in the shape of a flat plate or a corrugated plate, or may be provided with a heat insulating material or various functional materials on the upper surface thereof. Alternatively, a porous face plate having a large number of holes may be used, in which case the portion (face plate portion) can be formed by, for example, punching metal, and a heat insulating material or various functional materials may or may not be arranged. It is good, but sound absorption and light weight are taken into consideration.

The rising portion is a portion where the left and right sides of the face plate portion are raised upward, and may be substantially vertical or inclined, and an appropriately shaped engaging portion is formed in the vicinity of the base end thereof. The engaging portion may be a portion that engages with the holding member, or may be a portion to which a decorative material, a hanging metal fitting, or the like is attached.
It is desirable that this engaging portion is formed so as to project toward the face plate portion, and this engaging portion can be used as a pressing portion from the side to the holding member, so that the rising portion is deformed. This rising portion can be arranged at an appropriate position without occurring.

The support surface portion extends outward from the upper end of the rising portion, is a portion to be placed on the support base portion of the holding member, and is also a portion where adjacent ceiling materials are connected in a polymerized manner. Therefore, a mounting hole for driving the fixture may be formed in advance.
Since this support surface portion is placed in a polymerized manner on the support base portion of the holding member, the support surface portion is formed to be slightly larger than the width length of the support base portion of the holding member, so that the support surface portion can be completely placed from above. It can be attached in a mating shape. More specifically, if one of the left and right sides is located below and the other is located above, the lower support surface portion is formed slightly larger than the width of the support base portion, and the upper support surface portion is formed thereof. It may be formed slightly larger than (the width and length of the lower support surface portion).

The folded portion is a portion where the tip of the support surface portion is folded down, and the length thereof (folded length) is not particularly limited, but as described above, the support surface portion is held by the support base portion of the holding member. When the folded portion is formed to be slightly larger than the width of the above, the folded portion is attached in a locking shape when the support surface portion is attached in a fitted shape.

The holding member that supports the ceiling material is a member provided with a horizontal support base as described above, and a shaped steel such as C-shaped steel may be used as in the illustrated embodiment described later, or a strip-shaped steel. It may be a molded body of a steel material, or a plate-shaped material may be appropriately bent and used.
The size (width) of the support base portion is not limited as long as it can be driven with a fixing tool such as a screw while the support surface portion of the adjacent ceiling material is placed. Further, as described above, by forming the support surface portion of the ceiling material slightly larger than the width length of the support base portion, the support surface portion can be completely fitted from above in a fitted shape, so that the width of the support surface portion can be obtained in advance. Adjusted according to length.
Further, as the holding member, various configurations can be used as described above, but a continuous material having the same length as the ceiling material may be used, or a plurality of short materials installed at predetermined intervals may be used. ..

Further, the base (framework) to which the holding member is fixed is a cross beam in the illustrated embodiment described later, but the present invention is not particularly limited, and the fixing portion is appropriately placed along the base with a fixing tool. It should be fixed.

In the ceiling structure of the present invention, both the ceiling material and the holding member that supports the ceiling material are extremely simple, and the support surface portions formed on the ceiling materials adjacent to the left and right are polymerized and connected to the support base portion of the holding member. Since it is only necessary to do so, the construction can be easily performed even from the roof side, and the practical value is extremely high.
In particular, since it can be constructed from the roof side, no scaffolding or the like is required on the indoor side, so that a huge space for scaffolding and a huge cost for scaffolding are not required.

Further, when the engaging portion of the ceiling material is formed so as to project toward the face plate portion side, the construction can be performed extremely easily while pressing the engaging portion from the face plate portion side toward the holding member.
Further, when the face plate portion of the ceiling material is porous, the portion (ceiling surface portion) can be formed by, for example, punching metal, and even if a heat insulating material or a functional material is arranged, it is not arranged. It may be good, but sound absorption and light weight are taken into consideration.
In addition, if a decorative material or a hanging metal fitting can be attached between the engaging portions of the ceiling material adjacent to the left and right, it is possible to easily attach a decorative material such as a joint cap or a hanging metal fitting such as a lighting fixture. It is possible to improve the design and functionality.

Further, in the method of constructing the ceiling structure of the present invention, after performing a process in which the lower ends of the legs are fixed to the base and the holding member is erected from the roof side, from the roof side to the ceiling materials adjacent to the left and right. Since the provided support surface portion is connected in a polymerized manner on the support base portion of the holding member, each step can be performed extremely easily from the upper (roof) side. Therefore, there is no need for work such as assembling the scaffolding, and the practical value is extremely high.

First Example

As shown in FIG. 1A, the ceiling structure of the first embodiment of the present invention is a rising portion 12 that is raised upward on the left and right sides of the face plate portion 11 and has engaging portions 121, 121'near the base end. , 12', and the support surface portions 13, 13'that extend from the upper ends of the rising portions 12, 12'to the support base portion 21 side and are placed on the support base portion 21, and the support surface portion 13. , 13'composed of a ceiling material 1 having folded portions 14, 14'with the tips folded down, and a holding member 2 provided with a horizontal support base portion 21, and a support base provided on the holding member 2. On the portion 21, the support surface portions 13, 13'of the ceiling materials 1, 1 adjacent to each other on the left and right are connected in a polymerized manner.
The rising portion, the supporting surface portion, and the folded portion formed on the left and right sides of the face plate portion 11 are set to 12, 13, 14 on the upper surface side (left side in the drawing) at the time of polymerization, and on the lower surface side (the lower surface side). In the drawing, the right side) is distinguished as 12', 13', 14'.

The holding member 2 that supports the ceiling material 1 is a C-shaped steel (grooved steel with a lip), which is a continuous through material in the length direction and also serves as a structural material such as a beam.
Since the holding member 2 in the first embodiment is made of C-shaped steel as described above, the leg has a support base portion 21 whose upper flange is a horizontal horizontal piece and whose web is a vertical vertical piece. In the portion 22, the lower flange is a fixed portion 23 which is a horizontal horizontal piece, the tip of the upper flange (support base portion) 21 has a downward lip 211, and the tip of the lower flange (fixed portion) 23 has an upward direction. A lip 231 is provided.
The base 3 on which the holding member 2 is erected in FIG. 1 (b) is a skeleton that is a cross beam and is made of H steel or the like. In this embodiment, the base 3 is fixed to the base 3. The holding member 2 is erected (fixed) via 3b.

As described above, in the specification that the holding member 2 is a C-shaped steel, the following four assumptions are possible, and there are various combinations thereof.
(1) It is used as a pure ceiling material by placing equipment such as a solar cell on the ceiling material 1 or laying an exterior material (FIG. 11 described later).
(2) Install equipment on the indoor side via hanging metal fittings below the ceiling material 1.
(3) The ceiling material 1 is used alone and is also used as an exterior material.
When the ceiling material 1 also serves as an exterior material as in (1) and (2) above, if the joints can be seen from the lower side, a decorative material or joint cover is arranged in the recess or C-shaped steel. May be good. That is, by arranging the decorative material and the joint cover, the design as a ceiling surface can be obtained. Further, a face plate portion can be formed by using a punching material, or a heat insulating material can be laid on the face plate portion, and ancillary equipment can be further arranged via a hanging metal fitting or the like. The joint portion may or may not have a cover.
In the above (3), since the upper surface side of the ceiling material 1 is the exterior surface and the lower surface side is the ceiling surface, auxiliary equipment for the exterior may be arranged on the upper surface side, and auxiliary equipment for the ceiling may be arranged on the lower surface side. May be arranged.

The engaging portions 121, 121'of the ceiling material 1 in the first embodiment are not shown in FIG. 1 as a portion that engages with the holding member 2 or a portion to which a decorative material, a hanging metal fitting, or the like is attached. However, a joint cap, a hanging metal fitting, or the like, which will be described later, may be arranged between the engaging portions 121 and 121'.

The support surface portions 13 and 13'of the ceiling material 1 as the exterior material are portions that form the ceiling surface similarly to the face plate portion 11, and the support surface portions 13 and 13'are used as the support base portion 21 of the holding member 2. For fixing, a fixing screw or the like (not shown) may be driven in from above, but it is desirable to perform a water stop treatment to prevent rainwater or the like from entering from the fixing screw.
Further, the height dimension of the rising portions 12, 12'is slightly higher than that of the web (leg portion 22) of the holding member 2, and the width dimension of the supporting surface portions 13, 13' is slightly higher than that of the upper flange (support base portion 21). Since it is formed large in size, the ceiling material 1 can be completely attached to the holding member 2 from above.

The ceiling material 1 of the first embodiment is extremely simple in itself, and the ceiling materials 1 and 1 adjacent to each other on the left and right by a simple holding member (C-shaped steel) 2 provided with a horizontal support base 21. Can be easily connected and can be easily applied to the construction of the ceiling surface.

An insertion portion 43 along the flange (support base portion 21) is provided, and an engagement piece 441 is provided at the upper end of the upward piece 44.
The joint cap 4A is attached to the holding member 2 before the arrangement of the ceiling material 1, and the ceiling material 1 is attached after the joint cap 4A is attached to the holding member 2. At that time, the engaging portion 121 is attached so as to engage with the outside of the engaging piece 441 of the joint cap 4A. That is, when the ceiling material 1 is attached, it can be attached more stably, so that the joint cap 4A is temporarily fixed before being fixed by a screw or the like.

As shown in FIG. 2D, the hanging metal fitting 6 is made by integrating a plurality of metal processed pieces by welding or bolts and nuts 6b, and has a horizontal piece-shaped top having a pair of left and right strut tips 611 and 611. The plate portion 61 and the vertical piece portion 62 extend from the center of the top plate portion 61 to the indoor side in a hanging shape, and the lower end thereof is bent horizontally so that various lighting fixtures (not shown) are fixed. The piece 63 is provided. A mounting nut 631 or the like is fixed to the connecting horizontal piece 63 so that various lighting fixtures or the like can be easily mounted.
The hanging metal fitting 6 has a strut tip 611,611 attached to the inside of the engaging portions 121, 121'of the ceiling materials 1, 1 in a pressed shape, and is a piece material, so that the attachment position, quantity, etc. can be arbitrarily selected. ..

FIG. 3A shows an example of a construction procedure in which the joint cap 4A in FIG. 2 is previously attached to the holding member (C-shaped steel) 2, and first, as shown in FIG. 3B. The joint cap 4A is attached to the outside (web side) of the holding member 2. That is, this work is performed prior to the on-site construction, and the lower flange (fixing portion 23) and the web (leg portion 22) of the holding member 2 are covered by the decorative lower surface 41 and the vertical surface portion 42 of the joint cap 4A. It covers and is mounted on the upper flange (support base portion 21) so that the insertion portion 43 is aligned.
Next, the ceiling material 1 is arranged between the holding members 2 and 2 attached at predetermined positions as shown in FIG. 3C, but the arrangement interval between the holding members 2 and 2 is the face plate of the ceiling material 1. It is set according to the width and length of the unit 11. Further, as described above, the dimensions of the support surface portion 13 and the like of the ceiling material 1 are also formed according to the dimensions of the support base portion 21 of the holding member 2. Therefore, by dropping the ceiling material 1 from above (from the roof side) into the arrangement interval of the holding members 2 and 2, it can be easily and comfortably attached in a fitted shape, and the construction state of FIG. 3 (a) can be seen. Can be formed.

FIG. 4A shows an example of a construction procedure in which the joint cap 4B is first attached to the holding member (C-shaped steel) 2, and first, as shown in FIG. 4B, the holding member 2 Attach the joint cap 4B to the opening side. That is, this work is performed prior to the mounting work of the holding member 2, and the opening (lip 211,231) and the lower flange (fixing portion 23) of the holding member 2 are attached to the vertical surface portion 42 of the joint cap 4B. The holding member 2 is attached at a predetermined position in a state where the decorative lower surface 41 is covered and the insertion portion 43 is attached along the upper flange (support base portion 21).
The joint cap 4B used in the example is substantially the same as the joint cap 4A in FIG. 2A (however, the arrangement direction faces each other), but is substantially the same except that the engagement piece 441 is not provided. Therefore, the same reference numerals are given to the drawings and the description thereof will be omitted.
Next, the ceiling material 1 is arranged between the holding members 2 and 2 attached at predetermined positions as shown in FIG. 4 (c), but as described above, the arrangement interval between the holding members 2 and 2 is the ceiling. The holding members 2 and 2 are set according to the width and length of the face plate portion 11 of the material 1, and the dimensions of the support surface portion 13 and the like of the ceiling material 1 are also formed according to the dimensions of the support base portion 21 of the holding member 2. By dropping the ceiling material 1 from above (from the roof side) into the arrangement interval of, the ceiling material 1 can be easily and comfortably attached in a fitted shape, and the construction state of FIG. 4A can be formed.

FIG. 5A shows an example of a construction procedure in which the ceiling material 1 is previously attached to the holding member (C-shaped steel) 2 unlike the construction procedure of FIG.
First, as shown in FIG. 5B, the ceiling material 1 is attached to the holding member 2. That is, by this work, the support surface portion 13'of the ceiling material 1 is attached so as to be in contact with the upper flange (support base portion 21) of the holding member 2.
Next, the joint cap 4B is arranged as shown in FIG. 5 (c), but since the ceiling material 1 is arranged in advance, the insertion portion 43 is arranged so as to overlap on the support surface portion 13'. Will be set up. After that, since the ceiling material 1 located on the right side of the drawing is arranged, it is arranged in a polymerized manner in the order of the support surface portion 13'-the insertion portion 43-the support surface portion 13 from the lower side to the upper side. The construction state of (a) can be formed.

Second Example

6 (a) and 6 (b) show that the holding member 2B having a shape in which a metal plate material is cut out and bent into an appropriate shape (side view is in the shape of a letter and front view is substantially rectangular) is placed on the base 3 in advance. This is an example in which the ceiling materials 1 and 1 are engagedly attached to the left and right side edges 251 of the holding member 2B.
In the holding member 2B in this example, the front and rear surfaces 25 and 25 of the bottom surface portion 24 are raised substantially vertically and facing each other, and the upper ends of the front and rear surfaces 25 and 25 are bent outward substantially horizontally to support the support base. It is configured as parts 26 and 26.
The base 3 is a skeleton that is a cross beam, is made of C-shaped steel, and is arranged so as to lie down on the H-shaped steel 30 further arranged on the lower side.

The holding member 2B has rising portions 12, 12'(including engaging portions 121, 121') of the left and right ceiling materials 1, 1 on the left and right side edges 251,251 of the front and rear surfaces 25, 25, respectively. Since it is attached along the engagement shape (formed into a shape along the engagement shape), the ceiling material 1 can be attached more stably.

FIG. 7 is an example in which the holding member 2B is used as in FIG. 6, but is an example in which the joint cap 4B is attached between the holding members 2B and 2B adjacent to each other in the length direction thereof. The procedure for simultaneously constructing the material 1 and the joint cap 4B is shown.
This joint cap 4B is almost the same as the joint cap 4A (however, the arrangement direction faces each other), but it is almost the same except that it does not have the engaging piece 441. Therefore, the same reference numerals are given to the drawings. The explanation is omitted. Although the joint cap 4B does not cover the holding member 2B from the indoor side, it is common for the purpose of providing design between the ceiling materials 1 and 1 adjacent to the left and right.

In FIGS. 7 (a) and 7 (b), the holding members 2B having the above-mentioned structure are fixed in advance on the base 3, and the ceiling material 1 and the joint cap 4B are simultaneously constructed on the holding member 2B.
That is, the ceiling material 1 is attached to the holding member 2B located on the leftmost side from the left side thereof, and the joint cap 4B is attached while rotating from the right side thereof.
In particular, as shown in FIG. 7B, the length of the joint cap 4B is shorter than that between the bases 3 and 3 adjacent to each other in the length direction (between the holding members 2B and 2B adjacent to each other in the length direction). The joint cap 4B can be easily rotated and attached without being hindered by the holding member 2B (that is, the joint cap 4B is not in contact with the holding member 2B).
After that, as shown in FIG. 7 (c), the new ceiling material 1 can be easily attached so as to be fitted from above, and thereafter, the above procedure is repeated.

FIG. 8A shows a state in which three ceiling materials 1 are adjacent to each other on the left and right by repeating the above procedure, a cross-sectional view thereof is shown in FIG. 8B, and the ceiling material 1 is shown in FIG. 8C. The combination state with the joint cap 4B is shown.

In the ceiling structure constructed as shown in FIGS. 7 and 8, a ceiling surface in which the face plate portions 11 of the ceiling material 1 are continuous is formed, and joints are formed between the indoor side and the bases 3 and 3 at the joint portion. Since the state in which the cap 4B is arranged can be seen, the design is excellent.

9 (a) to 9 (c) show variations of the outer cover material attached to the vertical rail-shaped portion formed by the connecting portions of the ceiling materials 1 and 1 adjacent to each other on the left and right in the example of FIG. 2 (c). Shows. The outer cover material may be a through material (continuous material) or a piece material depending on the purpose, or may be a combination of a plurality of members.
However, in the example of FIG. 2C, the holding member 2 of the C-shaped steel is used, but in FIG. 9, the holding member 2B which is a molding material of the metal plate material is used.
