Description

本発明は、天井固定装置に係わり、更に詳しくは例えば天井から床面にわたって設ける間仕切パネルを天井に保持するための天井固定装置に関するものである。   The present invention relates to a ceiling fixing device, and more particularly to a ceiling fixing device for holding, for example, a partition panel provided from a ceiling to a floor surface on the ceiling.

通常、オフィスビル等の室内の天井には、吊り天井構造が多く採用されている。つまり、階上のスラブから垂下した吊支部材によって、縦横に張り巡らした天井支持杆を吊下げ状に保持し、該天井支持杆に天井パネルの周囲を係止する構造である。このような天井創造を有する室内に天井から床面にわたって間仕切パネルを設置する場合、間仕切パネルの天レールを天井支持杆に保持することになる。   Usually, a suspended ceiling structure is often used for indoor ceilings of office buildings and the like. That is, it is a structure in which a ceiling support rod stretched vertically and horizontally is held in a suspended shape by a suspension support member suspended from a slab on the floor, and the periphery of the ceiling panel is locked to the ceiling support rod. When installing a partition panel from the ceiling to the floor in a room having such a ceiling creation, the ceiling rail of the partition panel is held on the ceiling support rod.

特許文献１には、断面Ｈ型の梁の下フランジ部に、間仕切壁用下地材や天井用下地材等の下地材を取付金具を介して取付ける構造が記載されている。つまり、取付金具は、間仕切壁用下地材や天井用下地材等の下地材を取付けるための取付部から上方に向けて一対の上向き突片部を対向して突設し、各上向き突片部の一側端部に対向する別の上向き突片部の方向に向けて上横片部を突設するとともに各上向き突片部の他側端部に対向する別の上向き突片部の方向に向けて下当て横片部を突設し、対向する上向き突片部において一方の上向き突片部の上横片部と他方の上向き突片部の下当て横片部とが対向すると共に一方の上向き突片部の下当て横片部と他方の上向き突片部の上横片部とが対向し、下当て横片部よりも上横片部を上に位置させ、下当て横片部の上面部に弾性を有する防振材を取着し、両上横片部の先端間の距離を下フランジ部の巾以上とし、両下当て横片部の先端間の距離を下フランジ部の巾以下とし、対向する上横片部と下当て横片部との平面視における距離を下フランジ部の巾よりも狭くした構造である。   Patent Document 1 describes a structure in which a base material such as a partition wall base material or a ceiling base material is attached to a lower flange portion of a beam having an H-shaped cross section via a mounting bracket. In other words, the mounting bracket projects a pair of upward projecting pieces facing upward from a mounting portion for attaching a base material such as a partition wall base material or a ceiling base material, and each upward projecting piece portion. An upper horizontal piece projecting toward the direction of another upward projecting piece facing the one side end of the upper projecting piece and in the direction of another upward projecting piece facing the other end of each upward projecting piece The lower lateral piece of the lower projecting portion is provided so that the upper lateral piece portion of one upward projecting portion and the lower lateral portion of the other upward projecting piece portion face each other. The lower horizontal piece of the upward protruding piece and the upper horizontal piece of the other upward protruding piece are opposed to each other, the upper horizontal piece is positioned above the lower horizontal piece, and the lower horizontal piece Install an anti-vibration material with elasticity on the top surface, make the distance between the tips of the upper horizontal piece parts greater than the width of the lower flange part, and set the distance between the tips of the lower support horizontal piece parts to The following flange portion width, a structure that a distance in a plan view and narrower than the width of the lower flange portion of the horizontal piece portion and the lower abutting transverse piece on opposite.

しかし、特許文献１に記載の取付金具は、Ｈ型梁の下フランジ部の上面部にそれぞれ上横片部を載置すると共に下フランジ部の下面部に下当て横片部の上面部に取着した防振材を押圧して梁に取付けるようになっているので、取付作業自体は挿入し、４５度程度の回転だけで済むので簡単であるが、防振材を押圧して下フランジ部に保持されているだけであるので、複数の取付金具の取付部にわたって、間仕切壁を支持する上ランナや、天井材を保持するスタッドを取付けるまでは、脱落する恐れもある。また、取付金具とＨ型梁の下フランジ部とは係合のみで保持されているので、不安定感は否めない。   However, the mounting bracket described in Patent Document 1 mounts the upper horizontal piece portion on the upper surface portion of the lower flange portion of the H-shaped beam and attaches it to the upper surface portion of the lower contact horizontal piece portion on the lower surface portion of the lower flange portion. Since the attached anti-vibration material is pressed and attached to the beam, the installation work itself is easy to insert and only requires rotation of about 45 degrees. Since the upper runner that supports the partition wall and the stud that holds the ceiling material are attached over the mounting portions of the plurality of mounting brackets, there is a risk of dropping off. Moreover, since the mounting bracket and the lower flange portion of the H-shaped beam are held only by engagement, a sense of instability cannot be denied.
