Description

  The present invention relates to a hanger for ceiling construction for horizontally suspending a long-shaped field edge receiver with respect to a suspension bolt supported by a building structure.

  In a building structure, a ceiling material is generally supported in the following configuration.

  First, in the building structure, a suspension bolt holding insert or an anchor or the like is installed, and a plurality of elongated field edge receivers are horizontally supported with respect to the suspension bolt. In addition, a plurality of long-shaped field edges are attached below these field edge receivers so as to be orthogonal to each other via a ceiling construction clip. The ceiling material is fixed to a plurality of the field edges with screws or the like.

  The hanger for ceiling construction is a member for horizontally suspending a long-shaped field receiver with respect to a suspension bolt, and is installed by inserting a portion of the suspension into a suspension bolt and holding it between upper and lower nuts. And a field edge receiver is supported by inserting a field edge receiver in the insertion recessed part formed in the substantially concave shape of the lower end side. At this time, the height level of the field edge receiver can be adjusted by adjusting the position of the lower nut when it is installed on the suspension bolt.

  However, the ceiling construction hanger has a large number of installations, and it is difficult to make the level adjustment uniform. For this reason, there is a problem that the load load due to the edge receiving or the like concentrates on the partial ceiling construction hanger, and the fitting recess cannot withstand the concentrated load and spreads.

  Therefore, in order to make it difficult to spread the insertion recess until now, Japanese Patent Application Laid-Open No. 7-207809 discloses that a notch groove is formed at the upper end of the outer wall portion of the insertion recess into which the edge receiver is to be inserted, A notch that forms a receiving portion spreading prevention piece comprising an extending supporting piece and a locking piece at the upper end of the supporting piece is formed in a state in which the lower end portion of the supporting piece is left uncut, and the receiving portion spreading prevention piece is There has been proposed an invention relating to a hanger for ceiling construction that is configured such that the engaging piece can be engaged with a notch groove by causing it to occur on the front side of the main body (Patent Document 1).

  In addition, JIS standards (JIS A 6517) have been established for ceiling construction hangers, and various regulations and policies have been established by academic societies and the like regarding the method of attaching field guards using the ceiling construction hangers (non-patent) Document 1, Non-Patent Document 2, Non-Patent Document 3).

  However, in the invention described in Patent Document 1, when the receiving portion spreading prevention piece is locked in the notch groove, the locking is insufficient, the vibration due to the earthquake, the temperature difference between the indoor and outdoor, There is a problem that the receiving portion spread prevention piece comes off from the notch groove by receiving various vibrations such as vertical shaking of the ceiling due to the generated wind pressure.

  Therefore, it is necessary to carefully carry out the locking operation of the receiving portion spreading prevention piece, but at present, the number of ceiling hangers installed on the ceiling is very large, and since it is a simple operation, it is also required to work quickly. Therefore, uncertain construction is likely to be performed. In addition, if the ceiling material is pasted on the edge, the construction state of the hanger for ceiling construction is hidden and cannot be seen, so even if uncertain construction is performed, it is difficult to find the fence in advance.

  In addition, according to the JIS standard (JIS A 6517), it is supposed that a 吋 standard 3/8 wit screw is used for the suspension bolt. It is used. On the other hand, the nut uses 吋 standard 3 / 8-16 wit screws, and this nut has a trough diameter of 9.525 mm when converted to millimeters. There is also a problem that a relatively large gap is generated, and it is easily loosened by vibrations or the like.

  Therefore, although the provisions and policies of Non-Patent Document 1, Non-Patent Document 2, and Non-Patent Document 3 are established, there is a shortage of skilled workers, and there is a ceiling material fall accident due to breakage of the ceiling construction hanger. There is no end to it.

  The present invention was made in order to solve the above-described problems, and is a ceiling construction hanger that has high earthquake resistance and can perform reliable construction efficiently without requiring skill. It is intended to provide.
