Description

本考案は、天井下地材の一部である野縁や野縁受がボード壁を突き抜けないようにするための金具に関する。   The present invention relates to a metal fitting for preventing a field edge and a field edge receiving part of a ceiling base material from penetrating a board wall.

１９８１年以降に設計された建物は、新耐震設計法で建てられているため、震度6程度では崩壊せず、避難が可能と想定されている。そのため大地震でも骨組の損傷は少なくなっているが、非構造部材と呼ばれる天井の崩落や壁が倒れることで、死傷者や避難を遮断する被害が目立つようになった。   Buildings designed after 1981 are built according to the new seismic design method, so it is assumed that they will not collapse at seismic intensity of 6 and can be evacuated. As a result, the damage to the skeleton has been reduced even in the event of a major earthquake. However, damage to the casualties and evacuation has become more prominent due to the collapse of the ceiling, which is called a non-structural member, and the fall of the wall.

この難題を解決すべく、特許文献１や特許文献２で、天井の揺れを小さくすることが可能となるが、野縁や野縁受の小口と壁の間は、国土交通省のガイドラインで、壁際に隙間をあけるように「技術的助言」として通達されている。しかし、天井が揺れれば鋼製下地の野縁や野縁受の小口が、壁に衝突するため、ＡＬＣ板やボード壁などの比較的軟らかい壁に被害が発生した。従って、壁を衝撃から保護する小口塞ぎを提供することである。   In order to solve this challenge, it is possible to reduce the shaking of the ceiling in Patent Document 1 and Patent Document 2, but between the edge of the field edge and the edge of the field edge and the wall, according to the guidelines of the Ministry of Land, Infrastructure, Transport and Tourism, It is notified as "technical advice" to leave a gap at the wall. However, if the ceiling sways, the edge of the steel base and the edge of the edge of the edge collide with the wall, causing damage to relatively soft walls such as ALC boards and board walls. Therefore, it is to provide a small mouth closure that protects the wall from impact.

特許第４４６７５９２号公報Japanese Patent No. 4467759 実願２０１１−００４４３０号No. 2011-004430

天井材を留める野縁と、その上部に立体交差している野縁受の小口が、大地震の揺れによりＡＬＣ板やボード壁を突き抜け、上階の外壁が脱落する被害があり、技術的な改善が必要となった。   The edge of the field edge that holds the ceiling material and the edge of the field edge that crosses the top of the ceiling material penetrates the ALC board and board wall due to the shake of a large earthquake, and the outer wall of the upper floor is damaged. Improvement was needed.

請求項１の考案によれば、野縁や野縁受の小口のままでは、軟らかい壁に硬い金属製の野縁や野縁受が比較的小さい力でも刺さってしまうが、板状の小口塞ぎ部で壁に当る面積が増えることにより容易には刺さらなくなる。   According to the first aspect of the present invention, if the edge of the field edge or the field edge is left as it is, the hard metal field edge or the edge edge will pierce with a relatively small force on the soft wall. As the area hits the wall at the part increases, it is not easily pierced.

請求項２の考案によれば、板状の小口塞ぎ部にクッション材を取り付けることにより、軟らかい壁を傷つけなくてすむ。   According to the second aspect of the present invention, the soft wall can be prevented from being damaged by attaching the cushioning material to the plate-like small mouth closing portion.

請求項３及び請求項４の考案によれば、地震で野縁や野縁受が揺れた場合でも、スライド可能な構造になっているため、本考案の金具が落下せず施工時にも取り付けが容易である。   According to the inventions of claim 3 and claim 4, since the structure is slidable even when the field edge or the field edge receiver shakes due to an earthquake, the metal fitting of the present invention does not fall and can be attached even during construction. Easy.

本考案によれば、小口塞ぎ金物を野縁および野縁受の小口に挿入することで、柱や壁の損傷や壁の脱落を防止することが可能となる。   According to the present invention, it is possible to prevent damage to the pillars and walls and drop off of the wall by inserting the small edge closing metal fitting into the edge of the field edge and the edge of the field edge.

以下に本考案の実施の形態を添付図面に基づいて説明する。
本考案の天井鋼製下地材の小口塞ぎ金物を説明する。天井鋼製下地材の小口塞ぎ金物は野縁や野縁受と組み合わせるためのジョイント部２と壁などに衝突する面積を増加させるための板状の小口塞ぎ部３で構成される。ジョイント部２と小口塞ぎ部３は0.5ｍｍ程度の鋼製の板で作られ、スポット溶接で溶接される。小口塞ぎ部３の鋼製の板は野縁又はダブル野縁に用いる場合、高さ方向は野縁と同じであるが、横方向は野縁又はダブル野縁の2倍程度が望ましい。更に、板状の小口塞ぎ部３にクッション材４を貼り付けることによりボード壁を傷めることがない。クッション材４には、難燃性がありクッション性もある材質として、押出ポリスチレンに難燃剤を添加したものを用いるとよい。本考案の天井鋼製下地材の小口塞ぎ金物を野縁受に使用する場合は小口塞ぎ部３の大きさは、縦横共に野縁の断面より少し大きい程度でよい。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
An explanation will be given of the small-sized metal fittings of the ceiling steel base material of the present invention. The small clogging hardware of the ceiling steel base material is composed of a joint portion 2 for combining with a field edge and a field edge and a plate-shaped small wall closing part 3 for increasing an area colliding with a wall or the like. The joint part 2 and the small clogging part 3 are made of a steel plate of about 0.5 mm and are welded by spot welding. When the steel plate of the small clogging portion 3 is used for a field edge or a double field edge, the height direction is the same as the field edge, but the lateral direction is preferably about twice the field edge or the double field edge. Furthermore, the board wall is not damaged by sticking the cushion material 4 to the plate-shaped small blockage 3. As the cushion material 4, a material obtained by adding a flame retardant to extruded polystyrene may be used as a material having flame retardancy and cushioning properties. In the case of using the small steel capping hardware of the ceiling steel base material of the present invention for the field edge receiving, the size of the small edge closing part 3 may be a little larger than the cross section of the field edge both vertically and horizontally.

ジョイント部２は野縁と野縁受に用いる場合で異なった形状が望ましい。野縁又はダブル野縁に用いる場合は、野縁の左右のレール状になっている部分に差し込む形状が取り付け作業では便利である。野縁受に用いる場合は左右のレール状の形状が野縁受に無いため、ジョイント部２は野縁受を挟み込む形状となっている。これにより、野縁や野縁受のどちらでも、ワンタッチではめ込むことができるので、取り付け作業は非常に簡単である。しかも、大地震により野縁や野縁受が揺れた場合でも、ジョイント部２がスライドできる構造になっているので、簡単に脱落してしまうことがない。   The joint portion 2 is preferably different in shape when used for a field edge and a field edge receiver. When it is used for a field edge or a double field edge, a shape to be inserted into the left and right rail-shaped portions of the field edge is convenient for the installation work. When used for a field edge receiver, since the left and right rail-shaped shapes are not present in the field edge receiver, the joint portion 2 has a shape sandwiching the field edge receiver. As a result, it is possible to fit in either a field edge or a field edge with a single touch, so the installation work is very simple. In addition, even when the field edge or the field edge is shaken due to a large earthquake, the joint portion 2 is configured to be slidable, so that it does not easily fall off.

本考案によれば、大地震で大きな力が加わった場合でも野縁受や野縁の衝突による柱や壁の損傷を防ぎ、外壁の脱落を防ぐことができる。 According to the present invention, even when a large force is applied due to a large earthquake, it is possible to prevent damage to the pillars and walls due to the field edge and the collision of the field edge, and to prevent the outer wall from falling off.
