【発明の属する技術分野】
本発明は、天井下地材に用いられる天井下地材の野縁受に関する。
【0002】
【従来の技術】
従来、天井下地材の野縁受としては、建築用鋼製下地材のJIS A6517規格に示されるように、断面コの字形状のもの(CC−19)、またこのコの字形状の野縁受の上下端部を内側に屈曲形成した断面Cの字状の野縁受がある。
【0003】
野縁受の品質を評価する場合、JIS A6517規格では、図10に示す下向き荷重試験によって行われる。この試験では、吊ボルト51を用いて平行に野縁受52を架設し、この野縁受52にクリップを用いてシングル野縁53を取付け、野縁受52の上部に足場板54(1200×400×24mmの合板)を載置する。そして、この足場板54の上に735.50N(75kgf)の荷重をかけたとき、野縁受52の吊ボルト51間中央の最大たわみ量及び残留たわみ量を測定する。この試験に用いる野縁受(CC−19)は、断面コの字形状で板厚は1.2mmである。
【0004】
測定は野縁受52を2本について行い、いずれか大きな値をとる。規定に適合する野縁受の載荷強さは、最大たわみ量が5mm以下であり、かつ、上述した735.50N(75kgf)の荷重を取り除いたときの残留たわみ量が2mm以下となる性能が要求されている。この規定には、天井裏で作業を行う場合、足場板を野縁受に渡して作業することがあり、このとき735.50N(75kgf)の荷重を取り除いたとき、野縁受の残留たわみ量が少なく充分な復元力をもっていることが背景にある。
【0005】
【発明が解決しようとする課題】
さて、上記規格とは別に一般市場においては、板厚が1.0mmもしくは0.9mm等、製品コスト及び軽量化等の点で、JIS規格の野縁受と比べて板厚を薄くした野縁受が一般品として出回っている。このような板厚の薄い野縁受では、上記荷重試験を行った場合、板厚の関係で上記規格を満足する結果は得られない。しかし、市場においては、製品コストの削減、或いは軽量化の要望が根強い。
【0006】
本発明は、上記問題点に鑑みてなされたものであり、強度が維持され、経済性にも優れるとともに製品の軽量化、省資源化が図れる天井下地材の野縁受を提供することを課題としている。
【0007】
【課題を解決するための手段】
以上の技術的課題を解決するため、本発明に係る天井下地材の野縁受は、図1及び図2に示すように、天井部から吊下げられ、垂直方向に長い基板部21、この基板部の下端部から横方向に屈曲形成される受板部22、及びこの受板部からさらに上方に屈曲形成される側板部23を有するハンガー2、に嵌入支持される野縁受であって、上記ハンガー2の基板部21又は側板部23に接する上側の立上部11と、この上側の立上部11の上端部から、水平方向に屈曲形成される上板部12と、上記上側の立上部の下部から上記上板部の下方側に屈曲して、斜め下向に形成される傾斜部13と、この傾斜部の下部に形成され、上記ハンガー2の側板部23又は基板部21に接する下側の立上部14と、この下側の立上部14の下端部から、上記上板部と逆向の水平方向に屈曲形成される下板部15と、を有するものである。
【0008】
また、本発明に係る天井下地材の野縁受は、上記上板部の先端部から下方向きに上端縁部16を、上記下板部の先端部から上方向きに下端縁部17を設けたものである。
【0009】
これに加えて、本発明に係る天井下地材の野縁受は、上記傾斜部13の傾斜角度を水平から45度以上に形成したものである。
【0010】
【発明の実施の形態】
以下本発明の実施の形態に係る天井下地材の野縁受を図面に基づいて説明する。図1は、上記野縁受1の側面図を示したものであり、この野縁受1は鋼板を屈曲成形したものであり、略Z形状をしている。
【0011】
野縁受1は、垂直方向に形成される上側の立上部11、この上側の立上部11の上端部から、前方向に水平状に屈曲形成される上板部12、上記上側の立上部11の下部から屈曲して、前方斜め下方向に傾斜する傾斜部13、この傾斜部13の下部から下方垂直方向に形成される下側の立上部14、及び下側の立上部14の下端部から、後方向に水平状に屈曲形成される下板部15を有し、上記上板部12の先端部から下方垂直方向に上端縁部16が、上記下板部15の先端部から上方垂直方向に下端縁部17がそれぞれ設けられている。
【0012】
上記傾斜部13は、水平から略50度の角度を有している。また、上記野縁受1の上板部12及び下板部15は、下記ハンガー2の受板部22の内寸より僅かに短い長さを有している。
【0013】
上記野縁受1は、図2に示すように、天井スラブ等の天井部から吊下げられるハンガー2に嵌入支持される。このハンガー2は、天井スラブから吊下げられた吊ボルト3にナット4等により高さ調整可能に吊り下げられている。このハンガー2は鋼板を屈曲成形したものであり、垂直方向に長い基板部21、この基板部21の下端部から前方に水平に屈曲形成される受板部22、この受板部22からさらに上方垂直方向に屈曲形成される側板部23、及び基板部21の上端から後方に屈曲する支持部24を有している。
【0014】
このように上記ハンガー2は、基板部21、受板部22及び側板部23によって断面U字形状に形成され、上向の開口部27を有する。さらにハンガー2の側板部23の上部を、緩く後側に屈曲して係止部25を形成し、さらに前側斜め上方に屈曲してスライド部26を形成している。上記吊ボルト3にハンガー2の支持部24を挿通させ、支持部24の上下側からナット4を用いてハンガー2を固定する。
【0015】
野縁受1をハンガー2に装着する場合には、開口部27からスライド部26を利用して野縁受1を押し込み、野縁受1の下板部15がハンガー2の受板部22に当接する位置で、野縁受1の上端部が側板部23の係止部25に係止され、ハンガー2の断面U字形状の内部に野縁受1を嵌入保持する。この状態で、野縁受1の上側立上部11及び下端縁部17はハンガー2の基板部21に接する一方、野縁受1の下側立上部14及び上端縁部16はハンガー2の側板部23に当接する。
【0016】
なお、図3に示すように、ハンガー2の前後の向きを変えて、野縁受1を嵌入保持することとしても、作用効果は上記もとの向きの場合と同様である。この場合、野縁受1の下側立上部14及び上端縁部16はハンガー2の基板部21に接し、一方、野縁受1の上側立上部11及び下端縁部17はハンガー2の側板部23に当接する。
【0017】
上記野縁受1を用いて天井構造を構築する場合には、所定の間隔をおいて平行な位置に吊ボルト3をハンガー2を取付けて設置し、ナット4によってハンガー2の高さを調節する。そして、ハンガー2に野縁受1を嵌入してハンガー2間に野縁受1を架設する。
【0018】
さらに、図4に示すように、クリップ7を用いて野縁受1と直交する状態に野縁材5を設置する。このクリップ7には、基板の下部に野縁材5を係止する係止部28が設けられ、また基板の上部には野縁受1に引っ掛ける掛止部29を有している。野縁材5は断面C字状の長尺材であり、このC字溝にクリップ7の係止部28を係止させ、クリップ7の掛止部29を野縁受1に引っ掛けて、野縁材5を格子状に取り付ける。そして野縁材5の下面部に内装ボードを止着する。
【0019】
さて、図5及び図6に示すように、野縁受1を吊ボルト3及びハンガー2によって吊り下げ、平行状態の2つの野縁受1の各中央部の上部に足場板6を載置して、この足場板6に荷重(F)を加える。このとき野縁受1は荷重によって撓む(δ)。すると、野縁受1の上部立上部11及び下端縁部17の2点、上端縁部16及び下部立上部14の2点の計4点が、それぞれ接するハンガー2の基板部21及び側板部23に強く押しつけられ、さらに撓もうとするが、上部立上部11と下部立上部14との間に形成された傾斜部13の角度を水平から45度以上の略50度としているので、効果的に荷重を支え、撓みを防止する役割を果たす。
【0020】
上記野縁受1の性能を評価する荷重試験を、上記JIS A6517の規定に基づいて行った。図7(a)は上記野縁受1を、図7(b)はJIS規格19形(CC−19)の野縁受31を、図7(c)は一般用として用いられている野縁受32の形状を示したものである。野縁受としての、高さA(A=38mm)、幅B(B=12mm)等の基本的な外形のサイズは(a),(b),(c)共に同じである。異なる点は、野縁受1の厚さtは(t=0.5mm)であるのに対して、JIS19形の野縁受31の厚さtは(t=1.2mm)、一般用の野縁受32の厚さtは(t=0.9mm)である点、及び野縁受1は傾斜部13及び上下端縁部16,17を有する略Z字形状からなる点である。
【0021】
図9は、上記荷重試験の結果を示したものである。図7(c)の一般用野縁受32は、最大たわみ量5.46mm、残留たわみ量0.31mmであり、JISA6517の規定値(最大たわみ量5mm以下)を満たすことができない。これに対して、この実施の形態に係る図7(a)の野縁受1は、最大たわみ量4.27mm、残留たわみ量0.16mmであり、JISの規定値を満足する。
【0022】
また、図7(a)の野縁受1は、板厚を0.5mmとしているので、1m当りの単位重量は0.2988kg/mとなり、図7(c)に示す板厚0.9mmの野縁受32の単位重量0.4096kg/mの73%となる。このため実施の形態に係る図7(a)の野縁受1は、27%の省資源化が図れ、低コストの天井下地材が提供できる。また、図7(b)に示す板厚1.2mmのJIS規格の野縁受31と比較した場合、図7(a)の野縁受1は、重量比が54.6%であり、約45%の省資源化が図れる。
【0023】
図8は、野縁受の他の形態を示したものである。この野縁受41は、高さ(38mm)、幅(12mm)、及び厚さ(t=0.5)等の野縁受としての基本的な外形のサイズ、及び傾斜部13を有するZ形状である点は、図7(a)に示す野縁受1と同じである。この野縁受41は、傾斜部13の水平からの角度を略70度として、野縁受1より大きい角度としている。
【0024】
この図8に示す野縁受41について上記荷重試験を行った結果、図9に示すように野縁受41は最大たわみ量4.88mm、残留たわみ量0.57mmであり、JISの規定値を満足する。また、野縁受41の単位重量は0.2922kg/mであり、図7(c)に示す板厚0.9mmの野縁受32の単位重量0.4096kg/mの71.3%となり、省資源化が図れる。このように野縁受41は、図7(a)の野縁受1に比べてたわみ量の特性は少し劣っているものの、JIS規格は満足する。したがって、上記図7(a)の野縁受1及び図8の野縁受41の傾斜部13の角度からすれば、良好なたわみ量の特性を得るためには、傾斜部13の水平からの角度は、45度以上が好適と考えられる。
【0025】
従って上記実施の形態に係る野縁受によれば、野縁受の板厚を0.5mmと薄くしても、JIS A6517の下向き載荷荷重試験の最大たわみ量、残留たわみ量の規格を満たすことができ、十分な強度が維持され、かつJIS6517に規定されている板厚が1.2mmの野縁受(CC−19)と比べて材料の大幅な削減が図れ、経済性にも優れ、また板厚が0.9mmの一般品と比較しても材料の削減が図れ、省資源化にも寄与する。また、上記各野縁受は、一枚板からロールフォーミングで形成することが可能であり、このためスタット成形するときに必要なカシメ作業の必要がなく、周長も少なくて済むという利点がある。
【0026】
【発明の効果】
以上説明したように、本発明に係る天井下地材の野縁受によれば、ハンガーに嵌入支持される野縁受であって、ハンガーの基板部に接する上側の立上部と、水平方向に屈曲形成される上板部と、上側の立上部の下部から斜め下向に形成される傾斜部と、ハンガーの側板部に接する下側の立上部と、上板部と逆向の水平方向に屈曲形成される下板部と、を有するものとしたから、十分な強度が維持され、経済性にも優れるとともに製品の軽量化、省資源化が図れるという効果がある。
【0027】
また、本発明に係る野縁受によれば、上板部の先端部から下方向きに上端縁部を、下板部の先端部から上方向きに下端縁部を設けたから、強度が補強されるという効果がある。
【0028】
さらに本発明に係る野縁受によれば、傾斜部の傾斜角度を水平から45度以上に形成したから、十分な強度が確保できるという効果がある。

As described above, the hanger 2 is formed in a U-shaped cross section by the substrate portion 21, the receiving plate portion 22 and the side plate portion 23, and has an upward opening portion 27. Furthermore, the upper part of the side plate part 23 of the hanger 2 is gently bent rearward to form a locking part 25, and further bent obliquely upward to the front side to form a slide part 26. The support 24 of the hanger 2 is inserted through the suspension bolt 3, and the hanger 2 is fixed using the nut 4 from the upper and lower sides of the support 24.
[0015]
When the field receiver 1 is attached to the hanger 2, the field receiver 1 is pushed in from the opening 27 using the slide portion 26, and the lower plate portion 15 of the field receiver 1 is attached to the receiving plate 22 of the hanger 2. At the abutting position, the upper end portion of the field receiver 1 is engaged with the engagement portion 25 of the side plate portion 23, and the field receiver 1 is fitted and held inside the hanger 2 in a U-shaped cross section. In this state, the upper rising portion 11 and the lower end edge portion 17 of the field receiver 1 are in contact with the substrate portion 21 of the hanger 2, while the lower upper portion 14 and the upper edge portion 16 of the field receiver 1 are the side plate portions of the hanger 2. 23.

On the other hand, the field receiver 1 of FIG. 7A according to this embodiment has a maximum deflection amount of 4.27 mm and a residual deflection amount of 0.16 mm, which satisfies the specified values of JIS.
[0022]
7A has a plate thickness of 0.5 mm, the unit weight per meter is 0.2988 kg / m, and the plate thickness of 0.9 mm shown in FIG. The unit weight of the field receiver 32 is 73% of 0.4096 kg / m. For this reason, the field receiver 1 of FIG. 7A according to the embodiment can save 27% of resources and can provide a low-cost ceiling base material. Further, when compared with the JIS standard field receiver 31 having a plate thickness of 1.2 mm shown in FIG. 7B, the field receiver 1 in FIG. 7A has a weight ratio of 54.6%, about 45% resource savings can be achieved.
[0023]
FIG. 8 shows another form of field reception. The field receiver 41 has a basic outer size such as a height (38 mm), width (12 mm), and thickness (t = 0.5), and a Z shape having an inclined portion 13. This is the same as the field receiver 1 shown in FIG. The field edge receiver 41 has an angle larger than the field edge receiver 1 with the angle of the inclined portion 13 from the horizontal being approximately 70 degrees.
[0024]
As a result of performing the load test on the field edge receiver 41 shown in FIG. 8, the field edge receiver 41 has a maximum deflection amount of 4.88 mm and a residual deflection amount of 0.57 mm as shown in FIG. Satisfied. Further, the unit weight of the field receiver 41 is 0.2922 kg / m, which is 71.3% of the unit weight 0.4096 kg / m of the field receiver 32 having a plate thickness of 0.9 mm shown in FIG. Resource saving can be achieved. As described above, the field receiver 41 is slightly inferior to the field receiver 1 in FIG. 7A, but satisfies the JIS standard. Accordingly, in view of the angle of the inclined portion 13 of the field edge receiver 1 of FIG. 7A and the field edge receiver 41 of FIG. 8, in order to obtain a good deflection amount characteristic, It is considered that the angle is preferably 45 degrees or more.
[0025]
Therefore, according to the field receiver according to the above embodiment, even if the plate thickness of the field receiver is reduced to 0.5 mm, the standard of the maximum deflection amount and the residual deflection amount of the downward load load test of JIS A6517 must be satisfied. Compared with the field receiver (CC-19) with a thickness of 1.2 mm specified in JIS6517, the material can be greatly reduced, and it is excellent in economic efficiency. Compared with a general product with a plate thickness of 0.9 mm, the material can be reduced, contributing to resource saving. Further, each of the field supports can be formed by roll forming from a single plate, and therefore there is an advantage that there is no need for caulking work required for stat molding, and the circumferential length can be reduced. .
