Description

    The present invention relates to a reinforcing bracket having a locking structure between a field edge receiver and a ceiling field edge.

  Conventionally, as shown in FIG. 14, the ceiling base member mounting structure 10 is a structure in which a ceiling field edge 12 used for a foundation of a building ceiling is locked to a field edge receiver 14 using a clip member 16. A ceiling board 18 is attached to the field edge 12 with screws or the like (Patent Document 1). Reference numeral 20 denotes a hanger that hangs the field receiver 14.

  As shown in FIG. 14, the ceiling edge 12 is a channel-like long member, and a pair of side walls 26, 26 are provided so as to form a channel-like groove portion 24 that opens upward at both ends of the bottom wall 22. The upper ends of the side walls 26 and 26 are bent inward to form side wall locking portions 28 and 28. The field edge receiver 14 is a channel-like long member similar to the ceiling edge 12, and an upper wall 34 and a lower wall 35 are formed so as to form channel-shaped grooves 32 that open laterally at both upper and lower ends of the vertical wall 30. Is provided.

  As shown in FIG. 15, the clip member 16 has hook portions 38, 38 at both ends of the lower end of the substrate portion 36 and can be bent at the upper end portion of the substrate portion 36 (see FIG. 15). In the example shown, it has a structure in which three are provided.

  The field edge receiver 14 and the ceiling field edge 12 are attached so as to cross each other (FIG. 14), and the operation is performed as follows. The hook portions 38, 38 of the clip member 16 are locked to the side wall locking portions 28, 28 of the ceiling edge 12, and the base plate portion 36 of the clip member 16 is brought into contact with the vertical wall 30 of the edge receiver 14. In this state, the upper end locking portion 40 of the clip member 16 arranged on the upper wall 34 of the field receiver 14 is bent downward so as to be locked to the upper wall 34, and is fixed to the field receiver 14. In this manner, the field edge receiver 14 and the ceiling field edge 12 are fixed by the clip member 16 in a cross-engaged state.

  The above-mentioned conventional field edge receiving and ceiling field edge locking structure is such that the field edge receiver 14 and ceiling field edge 12 are moved downward so as to lock the upper end locking portion 40 of the clip member 16 to the upper wall 34. Since it is structured to be bent and locked to the field edge receiver 14, when an upper force is applied to the upper end locking portion 40 of the clip member 16, for example, when an earthquake occurs or a typhoon strikes, etc. This means that the bent locking portion of the upper end locking portion 40 is loosened due to the shaking, and the clip member 16 is detached from the field edge receiver 14 so that the engagement between the field edge receiver and the ceiling field edge cannot be maintained. There was a disadvantage that such an accident might occur.

  In order to eliminate the inconvenience as described above, for example, as shown in FIG. 16, the ceiling edge 12 and the edge receiver 14 are connected and fixed with screws 42, but it is necessary to perform an extra screw fixing operation. , There is a disadvantage that the work becomes complicated by that much. Further, as shown in Patent Document 2, there is also a proposal for further fixing and supporting the clip member by the clip holder, but the occurrence of the accident that the clip member is detached from the field receiver by the attachment of the clip holder is solved. However, it is indispensable to perform the work of attaching the clip holder, and it is inevitable that the work becomes complicated accordingly.
