Description

  The present invention relates to a suspended ceiling device intended for earthquake resistance.

  The fact that there are various suspension ceiling structures to be constructed in a building is also apparent from the inventions exemplified below. In particular, in the case of a suspended ceiling structure that requires earthquake resistance, the bottom surface of the ceiling material A support construction method is effective in which a holding member is installed on the ceiling to prevent the ceiling finishing material from falling. In the support construction method, the ceiling finishing material is a metal spandrel. However, the metal spandrel is not easily cracked or chipped, and it is a material that can secure the integrity of the surface by being connected to the edge. The pitch can be widened, and a net or the like may be used when taking measures to prevent falling from the ceiling finish surface for metal ceilings and board ceilings other than the spandrel.

  Conventionally, the ceiling material is the base material that connects the ceiling finishing material and the ceiling finishing material, and is an attached metal material such as a field edge, field edge receiver and clip, hanger, suspension bolt, etc. The suspension source is the suspension bolt, floor, roof The holding member is a member installed on the lower surface of the ceiling material in order to prevent the ceiling material from falling.

  Therefore, in order to prevent the ceiling material from falling, the present invention aims to improve the holding member installed on the lower surface of the ceiling material, and absorbs the vibration even if the ceiling material vibrates greatly due to a large-scale earthquake. An object of the present invention is to provide a safe suspended ceiling device that can be distorted or prevent the ceiling material from falling.

In the present invention, through holes are provided in the left and right connecting plates of the connecting body provided inside the holding member provided with a fastening flange to the ceiling material between the upper end portions of the left and right side plates, and the through holes are provided in the connecting body. A screw is screwed from the outside by communicating between the mounting plate and the groove row portion provided outside, a connecting member is placed on one side plate portion of the holding member, and a head of the screw is arranged in the groove row portion to form a groove. A female screw is provided at the outer end of the row portion, a receiving member installed horizontally is connected to such a connecting member, and a receiving member installed on the lower surface of the ceiling material is installed between the holding members. It is a suspended ceiling device.

  First, since the holding member for the suspended ceiling is integrally provided with the flange, a metal fitting is not required, and the material cost and the number of processes can be reduced.

  Secondly, the connecting body of the holding member has a simple structure that can be fastened with a screw from the outside after being inserted into the hollow portion of the holding member.

  Third, since the receiving member can move left and right by abutting a screw with the groove row portion of the holding member, the receiving member is connected to the holding member at an arbitrary position that does not interfere with the lighting fixture installed on the ceiling portion. The member can be fixed.

  Fourthly, the fastener can be incorporated in the hollow portion of the holding member and fastened with a screw from the outside, and the threading of the long screw can be easily performed from above and below.
