Description

  The present invention is an improvement of the installation structure of the underfloor storage, and more specifically, the beam member can be freely removed when it is necessary to dive under the floor from the installation location of the underfloor storage for inspection work and the like, and Further, the present invention relates to a hanging support structure for an underfloor storage that is excellent also in the supporting strength of the load of the storage box.

  Recently, in a house or the like, in order to effectively use a dead space under the floor, a storage that is installed under the floor by removing the floor board is known.

  In the conventional underfloor storage, a support arm is attached to each of the opposed portions of the opening edge of the removed floor board, and a support member is formed by horizontally placing a beam material on the tip side of these support arms. In addition, a configuration that can support the storage box is disclosed (for example, see Patent Document 1).

  However, since the hanging bracket of the disclosed underfloor storage is assembled by inserting a support arm through a slit formed on the upper surface of the beam member (support member), once installed, the upper end is joisted or the like. It cannot be removed because it is fixed with screws.

  Therefore, the beam material of the hanging support for supporting the lower surface of the storage room cannot be removed, and the storage room is removed in order to maintain and inspect the piping under the floor of the housing facility, and the opening part is submerged under the floor. There is dissatisfaction that this beam material interferes when trying to insert.

In addition, in the hanging metal fitting bent into an L shape, if an excessive weight load is applied to the metal fitting when an article or the like is stored in the storage, the bent portion may be deformed. Sufficient support strength is also required.
