Description

  The present invention relates to a base reinforcing material mounting hardware that engages with a substantially rectangular field edge arranged at a predetermined pitch and holds a base reinforcing material arranged on the back side of a ceiling material.

  2. Description of the Related Art Conventionally, indoor ceilings of buildings such as houses are provided with long field edges (base materials) made of lightweight steel frames or the like at a predetermined pitch, and a gypsum board having fire resistance as a ceiling material is fixed thereto with screws or the like. It is common.

  When fixing or suspending heavy objects such as lighting fixtures on such ceilings, sufficient pulling strength cannot be obtained even if they are fixed to gypsum board with gypsum sandwiched with cardboard using screws etc. There is a risk of heavy objects falling.

  In order to solve such a problem, Japanese Patent Laid-Open No. 2001-207572 (Patent Document 1) discloses a gypsum that uses a reinforcing base plate mounting bracket as a reinforcing base plate that provides sufficient pulling strength when screwed. A technology for disposing the back side of the board is disclosed, and according to this technology, the reinforcing base plate can be fixed to the reinforcing base plate mounting bracket without screwing, so that the mounting work of the reinforcing base plate can be easily performed.

  However, the above-described conventional example has the following problems.

  (1) There is only a single pressing piece at the center of the metal fitting, and there is a possibility that a reinforcing base plate such as a plywood cannot be stably pressed. That is, if a portion not pressed by the pressing piece is pressed from below, the reinforcing base material may be lifted.

  (2) The field edge and the reinforcing base plate mounting bracket must be fixed with screws, which is dangerous because it requires a screwing operation using a heavy electric tool at a high place such as the ceiling. There is a problem that there is a physical load, and furthermore, there is a problem that the position of the reinforcing base plate mounting bracket after screwing cannot be easily changed.

  (3) Since the contact piece (fourth contact piece) that contacts the lower surface of the reinforcing base plate is only on one side (third contact piece side), it is 1 when it is desired to continuously arrange the reinforcing base plate across the edge. The reinforcing base plate mounting bracket must be displaced and fixed to the long base material of the book, and as a result, the reinforcing base plate mounting bracket cannot be placed in the center of the reinforcing base plate. There is a problem that the support stability performance of the base plate is poor and a plurality of reinforcing base plate mounting brackets must be used to maintain the support stability.

  The present invention solves the above-mentioned problems, and the object of the present invention is to stably support the base reinforcing material and to easily attach and detach the base reinforcing material mounting hardware to the field edge.
