Thereby, since the base material fixing tool 1 can firmly support the base material 13, the base material 13 may be detached from the base material fixing tool 1 or displaced relative to the base material fixing tool 1. It can prevent.

Further, in the base material fixture 1 according to the present embodiment, the field edge fixing portion 2 is located downward from the upper plate portion 4 disposed along the upper surface of the field edge 12 and both side edge portions of the upper plate portion 4. The upper pressing piece 8 and the lower support piece 7 protrude laterally from the pair of side plates 5 respectively, and have a pair of side plates 5 extending along the side surfaces of the field edge 12. Thereby, one base material fixing tool 1 can support both the base material 13 disposed on one side of the edge 12 and the base material 13 disposed on the other side.
In addition, the upper plate portion 4 is disposed along the upper surface of the field edge 12 and the pair of side plate portions 5 sandwich the field edge 12 from the side. It can prevent rotating around. Thus, the weight of the base material 13 supported by the upper pressing piece 8 and the lower support piece 7 protruding from one side plate portion 5 of the pair of side plate portions 5 and the upper pressing portion protruding from the other side plate portion 5 Even when the weight of the base material 13 supported by the piece 8 and the lower support piece 7 is different, each base material 13 can be supported in a stable state.

  Moreover, in the base material fixture 1 according to the present embodiment, the pair of side plate portions 5 is configured to be able to sandwich the field edge 12 in the width direction. As a result, the outer edge fixing portion 2 can be prevented from coming off the outer edge 12 or being displaced relative to the outer edge 12. Therefore, the base material fixing tool 1 supports the base material 13 in a stable state. Can. In this embodiment, the base material fixing tool 1 can be prevented from being detached from the field edge 12 by holding the field edge 12 in the width direction by the pair of side plate portions 5. The fixing device is not fixed to the edge 12 of the field. As described above, since screwing work becomes unnecessary in the installation of the base material fixing tool 1, it is possible to improve the workability and reduce the cost for manufacturing the base material fixing tool 1 and installing it on the rim 12. can do.

As mentioned above, although the embodiment of the foundation material fixing tool, ceiling structure, and foundation material attachment method by the present invention was described, the present invention is not limited to the above embodiment and can be suitably changed in the range which does not deviate from the meaning It is.
