[Technical field to which the invention belongs]

 The present invention relates to a ceiling plate supporter that is installed between a floor and a ceiling to support the ceiling plate.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, a support tool for supporting a ceiling plate when fixing the ceiling plate by nailing the ceiling plate is known. Such a ceiling plate supporter is installed between the floor and the ceiling to support the ceiling plate, and has an outer cylinder pipe and an inner cylinder pipe of different diameters that can be expanded and contracted according to the height of the ceiling. It is equipped with a pillar that is slidably fitted. Then, the inner tube is pulled out from the outer tube, the height of the column is adjusted according to the height of the ceiling, and then the inner tube is fixed so that the column supports the ceiling. However, when the ceiling plate is supported by directly abutting the upper end of the pipe-shaped inner cylinder tube on the ceiling, the load of the ceiling plate concentrates on one point of the inner cylinder tube, and a partial depression occurs in the ceiling plate. There is danger. For this reason, in this type of ceiling plate supporter, a wide contact plate is usually attached to the upper end of the inner tube to disperse the load on the ceiling plate. However, when a ceiling plate is supported by such a single contact plate, the ceiling plate wobbles in the front, rear, left, and right directions around the contact plate supporting the ceiling plate, and the ceiling plate cannot be stably supported. For this reason, there is also known a supporting tool configured to stably support the ceiling plate by arranging two contact plates side by side with a gap therebetween. Such a support that supports the ceiling plate with two contact plates increases the stability of the ceiling plate compared to the case where a single contact plate supports the ceiling plate, but it is an extension line connecting the two contact plates. On the other hand, in the direction orthogonal to the ceiling plate, the ceiling plate cannot be reliably supported because it still wobbles. Further, in this type of support, generally, the contact plate is fixedly attached to the inner tube, and the interval between the contact plates cannot be adjusted, which is inconvenient. In other words, when holding a large ceiling plate, a wide spacing plate can support more stably, but when supporting a relatively small ceiling plate, a wide spacing plate will interfere with the flat plate. A compact support with a narrow space between the plates is more convenient to handle. However, with a support fixture that has a contact plate fixedly attached to the inner tube, the spacing between the contact plates cannot be adjusted according to the size of the ceiling plate, so a support device suitable for the size of the ceiling plate must be provided. It is necessary to prepare various types, which is wasteful in terms of cost, and also the storage and management of the support becomes complicated.

The present invention is intended to solve such a problem, and it is a first object of the present invention to provide a ceiling plate supporter capable of stably supporting the ceiling plate and securely holding the ceiling plate. The purpose of. A second object of the present invention is to provide a support member for the ceiling plate, which can adjust the interval between the contact plates supporting the ceiling plate.
