Description

本発明は、用いる部材(天井材及び保持部材)が簡易で、しかも施工を極めて容易に行うことができる天井構造に関する。 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.

鉄骨躯体からなる横梁(躯体)に対してタイトフレームを固定し、該タイトフレームに折板を敷設する屋根構造は広く知られている。
このような屋根構造では、横梁の長手方向に対して直交する方向に折板が敷設されている。また、横梁は、屋根材の形状等から3~5mの間隔で構築されるため、タイトフレームの取付、屋根材の敷設等の作業時に室内側に足場を設置するためスペースが必要となる。
また、この場合の天井構造は、一般に、前記屋根構造の施工とは、別々に行われている。
そのため、屋根を施工した後に、体育館などで、天井施工を行おうとすると、その天井施工のみで、足場などが必要であった。
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 constructing the roof, scaffolding or the like was required only for the ceiling construction.

例えば特許文献1には、構造材2の上フランジ21に縦長の外装材保持材4を固定し、前記構造材2,2間に化粧材3を架設した構造が提案されている。
また、特許文献2には、天井材の側縁を取り付けるための支持具と、外装材を取り付けるための支持具とがほぼ同一位置に二階建て状に固定された構造が提案されている。
For example, Patent Document 1 proposes a structure in which a vertically long exterior material holding material 4 is fixed to an upper flange 21 of a structural material 2 and a decorative material 3 is erected between the structural materials 2 and 2.
Further, Patent Document 2 proposes a structure in which a support for attaching a side edge of a ceiling material and a support for attaching an exterior material are fixed in a two-story form at substantially the same position.

しかしながら、前記特許文献1では、例えば縦長の外装材保持材4などが、前記特許文献2では、二階建て状に固定された支持具などが、何れも複雑な部材であるにもかからわず、これらの部材を用いる必要があった。また、外装材の接続位置と天井材の接続位置とが上下に連なっているため、極めて施工が困難であるという問題をも有するものであった。 However, in Patent Document 1, for example, a vertically long exterior material holding material 4 and the like, and in Patent Document 2, a support fixed in a two-story shape and the like are both complicated members. , It was necessary to use these members. Further, since the connection position of the exterior material and the connection position of the ceiling material are connected vertically, there is a problem that the construction is extremely difficult.

そこで、本発明は、用いる部材(保持部材及び天井材)が簡易で、しかも施工を極めて容易に行うことができる天井構造を提案することを目的とする。 Therefore, an object of the present invention is to propose a ceiling structure in which the members (holding member and ceiling material) used are simple and the construction can be performed extremely easily.

本発明は、上記に鑑み提案されたもので、水平状の支持台部を備える保持部材と、面板部の左右に、上方へ立ち上げられた立上り部、該立上り部の上端から前記支持台部側へ延在して該支持台部上にて載置される支持面部、該支持面部の先端が折り下げられた折下げ部、を備える天井材と、からなる天井構造であって、前記保持部材の前記支持台部上にて、左右に隣り合う前記天井材の前記支持面部が重合状に接続されていることを特徴とする天井構造に関するものである。 The present invention has been proposed in view of the above, and is a holding member having a horizontal support base portion, a rising portion raised upward on the left and right sides of the face plate portion, and the support base portion from the upper end of the rising portion. A ceiling structure comprising a ceiling material including a support surface portion extending to the side and mounted on the support base portion, and a folded portion in which the tip of the support surface portion is folded down, which is the holding. The present invention relates to a ceiling structure characterized in that the support surface portions of the ceiling materials adjacent to each other on the left and right are connected in a polymerized manner on the support base portion of the member.

また、本発明は、前記天井構造において、前記天井材の前記面板部が多孔性であることを特徴とする天井構造をも提案する。 The present invention also proposes a ceiling structure characterized in that the face plate portion of the ceiling material is porous in the ceiling structure.

また、本発明は、前記天井構造において、前記天井材の前記支持面部上には屋根構造が施工されることを特徴とする天井構造をも提案する。 The present invention also proposes a ceiling structure characterized in that a roof structure is constructed on the support surface portion of the ceiling material in the ceiling structure.

本発明の天井構造は、用いられる天井材も保持部材も極めて簡易であって、保持部材の支持台部に対し、左右に隣り合う天井材に形成した支持面部を重合状にさせて接続すればよいので、例えば屋根側からでも容易に施工を行うことができ、実用的価値が極めて高いものである。特に屋根側から施工できるため、室内側に足場等も必要としないので、足場のための巨大なスペースも足場形成のための膨大な費用も必要とすることがない。また、天井構造は、屋根構造には全く制限を受けないので、流れ方向に沿う方向にも流れ方向に直交する方向にも容易に適用することができ、各種の屋根構造にも容易に適用することができる。 In the ceiling structure of the present invention, both the ceiling material and the holding member used are extremely simple, and if 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 good, it can be easily constructed even from the roof side, for example, and has extremely high practical value. 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, since the ceiling structure is not limited to the roof structure at all, it can be easily applied in the direction along the flow direction and in the direction orthogonal to the flow direction, and can be easily applied to various roof structures. be able to.

また、天井材の面板部が多孔性である場合、例えばパンチングメタルにて当該部分(面板部)を形成することができ、断熱材や機能性材を配設しても配設しなくてもよくなり、また、吸音や軽量等を考慮したものとなる。 Further, when the face plate portion of the ceiling material is porous, the portion (face plate portion) can be formed by, for example, punching metal, and the heat insulating material or the functional material may or may not be arranged. It will be better, and the sound absorption and light weight will be taken into consideration.

また、天井材の支持台部上に屋根構造が施工される場合には、下地の傾斜勾配等に応じて適宜に天井材の配設方向を決定するが、屋根構造については天井構造には全く制限を受けないので、適宜に縦葺きでも横葺きでも任意に選択することができる。 In addition, when the roof structure is constructed on the support base of the ceiling material, the arrangement direction of the ceiling material is appropriately determined according to the slope of the base, etc., but the roof structure is completely different from the ceiling structure. Since there are no restrictions, it is possible to select either vertical or horizontal roofing as appropriate.

The ceiling structure is composed of a ceiling material including a support surface portion mounted on the support base portion and a folded portion in which the tip of the support surface portion is folded down, and the support base portion of the holding member. Above, the support surface portions of the ceiling materials adjacent to each other on the left and right are connected in a polymerized manner.

前記天井構造に用いられる保持部材は、前述のように水平状の支持台部を備えるものであって、後述する図示実施例のように脚部と該脚部の下端を水平状に延在させた固定部とを備えることが好ましい。この保持部材は、天井材と同程度の長さを備えるものでもよいし、ピース状でもよい。
前記支持台部は、その大きさ(幅長)を限定するものではなく、隣り合う天井材の支持面部を載置させた状態でビス等の固定具を打ち込むことができるものであればよい。
そのため、この保持部材としては、後述する図示実施例にも示すようにC形鋼等の型鋼を用いてもよいし、或いは板状材を適宜に折り曲げて用いてもよい。
The holding member used in the ceiling structure includes a horizontal support base as described above, and the legs and the lower ends of the legs extend horizontally as in the illustrated embodiment described later. It is preferable to provide a fixed portion. The holding member may have a length similar to that of the ceiling material, or may be in the shape of a piece.
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.
Therefore, as the holding member, a shaped steel such as C-shaped steel may be used as shown in the illustrated embodiment described later, or a plate-shaped material may be appropriately bent and used.

なお、前記天井構造の上方側には、各種の屋根構造を適宜施工することができるが、原則的にこれらの天井構造と屋根構造とは何ら制限がないので、それぞれの構造や敷設形式、敷設方法にも制限がない。
後述する図3及び図4に示す図示実施例には、保持部材の支持台部上にて天井材の支持面部同士を重合状に接続した部分を取付下地面として屋根構造を施工した例を示している。
Various roof structures can be appropriately constructed on the upper side of the ceiling structure, but in principle, there are no restrictions on these ceiling structures and roof structures, so each structure, laying type, and laying There are no restrictions on the method.
In the illustrated examples shown in FIGS. 3 and 4, which will be described later, an example is shown in which a roof structure is constructed using a portion in which the support surface portions of the ceiling material are polymerized on the support base portion of the holding member as a mounting base surface. ing.

また、この保持部材が固定される下地(躯体)は、後述する図示実施例では横梁であるが、特に限定するものではなく、前記固定部を下地上に沿わせて適宜に固定具にて固定すればよい。 Further, the base (framework) to which the holding member is fixed is a cross beam in the illustrated embodiment described later, but is not particularly limited, and the fixing portion is appropriately fixed with a fixing tool along the base. do it.

前記天井構造に用いられる天井材は、前述のように面板部と、その左右に、上方へ立ち上げられた立上り部と、該立上り部の上端から前記支持台部側へ延在して該支持台部上にて載置される支持面部と、該支持面部の先端が折り下げられた折下げ部と、を備えている。なお、この天井材は、内装材の一つであるため、屋根構造とは異なり、原則的に平坦状に天井面を形成する部材であって、その配設方向も、屋根勾配の流れ方向に沿う方向にも流れ方向に直交する方向でもよい。 As described above, the ceiling material used for the ceiling structure includes a face plate portion, a rising portion raised upward on the left and right sides thereof, and a support extending from the upper end of the rising portion toward the support base portion. It includes a support surface portion that is placed on the base portion, and a folded portion in which the tip of the support surface portion is folded down. Since this ceiling material is one of the interior materials, unlike the roof structure, it is a member that basically forms the ceiling surface in a flat shape, and its arrangement direction is also in the flow direction of the roof slope. It may be along the direction or in a direction orthogonal to the flow direction.

前記面板部は、天井面を形成する部位であって、平板状でも波板状でもよいし、その上面に断熱材や各種の機能性材を配設してもよい。或いは多数の孔を有する多孔性面板でもよく、その場合、例えばパンチングメタルにて当該部分(面板部)を形成することができ、断熱材や各種の機能性材を配設してもしなくてもよいが、吸音や軽量等を考慮したものとなる。 The face plate portion is a portion forming 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, for example, the portion (face plate portion) can be formed by 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.

前記立上り部は、前記面板部の左右が上方へ立ち上げられた部位であって、略垂直状でも傾斜状でもよく、或いは基端付近に、適宜係合部を形成したものでもよい。この係合部としては、保持部材に係合する部位としてもよいし、内側へく字状に突出させて化粧材や吊り金具等が取り付ける部位としてもよい。 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, or an engaging portion may be appropriately formed in the vicinity of the base end. The engaging portion may be a portion that engages with the holding member, or may be a portion that protrudes inward in a dogleg shape and to which a decorative material, a hanging metal fitting, or the like is attached.

前記支持面部は、前記立上り部の上端から外側へ延在して前記保持部材の支持台部上に載置される部位であって、隣り合う天井材が重合状に接続される箇所でもあるため、予め固定具を打ち込む取付孔を形成しておいてもよい。
この支持面部は、前記保持部材の支持台部上にて重合状に載置されるので、左右の一方が下方に位置し、他方が上方に位置するとすれば、下方の支持面部は、支持台部の幅長より僅かに大きく形成され、上方の支持面部は、それ(下方の支持面部の幅長)より大きく形成されればよい。
The support surface portion extends outward from the upper end of the rising portion and is 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. , 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, if one of the left and right is located below and the other is located above, the lower support surface portion is the support base. The upper support surface portion may be formed slightly larger than the width length of the portion, and the upper support surface portion may be formed larger than that (the width length of the lower support surface portion).

前記折下げ部は、前記支持面部の先端が折り下げられた部位であって、特にその長さ(折り下げ長さ)については限定しないが、前述のように左右の一方の支持面部が下方に位置し、他方の支持面部が上方に位置するとすれば、下方の支持面部の先端を折り下げた折下げ部は、前記立上り部の内面側に沿うように折り下げられ、上方の支持面部の先端を折り下げる折下げ部には、そのような限定はない。 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, one of the left and right support surface portions is downward. If it is located and the other support surface portion is located above, the folded portion in which the tip of the lower support surface portion is folded down is folded down along the inner surface side of the rising portion, and the tip of the upper support surface portion is folded down. There is no such limitation on the folding part that folds down.

本発明の天井構造は、用いられる天井材も保持部材も極めて簡易であって、保持部材の支持台部に対し、左右に隣り合う天井材に形成した支持面部を重合状にさせて接続すればよいので、屋根側からでも容易に施工を行うことができ、実用的価値が極めて高いものである。
特に屋根側から施工できるため、室内側に足場等も必要としないので、足場のための巨大なスペースも足場形成のための膨大な費用も必要とすることがない。
In the ceiling structure of the present invention, both the ceiling material and the holding member used are extremely simple, and if 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.
