Description

  The present invention relates to a floorboard support for supporting a floorboard of a building, and more particularly to a floorboard support that can be adjusted in height from above the floorboard.

  Conventionally, the intermediate part of the cross beam (large drawing) arranged under the floor of the building has been supported by a steel bundle standing on a concrete foundation. For example, as shown in FIG. 11, the steel bundle includes a base plate 51 installed on the concrete foundation C, a lower screw rod 52 erected on the base plate 51, and a concentrically screwed upper portion thereof. A cylindrical turnbuckle 53, an upper screw rod 54 screwed onto the upper portion, and a top plate 55 attached to the upper portion and supporting the large pull 56 (for example, Patent Document 1). reference).

Since the lower screw rod 52 and the upper screw rod 54 are threaded in opposite directions, turning the turnbuckle 53 causes the screw rods 52 and 54 to expand and contract. Thus, the height position of the large pull 56 can be adjusted. That is, when the turnbuckle 53 is normally operated under the floor and rotated in the forward direction, the claw rods 52 and 54 are extended so as to be separated from each other to lift the large pull 56 and rotate in the reverse direction. The height of the large pull 56 can be reduced by contracting the screw rods 52 and 54 so as to approach each other.

An operation member operable from above with an operation tool, and the operation member includes a bolt whose upper portion is a polygonal head portion, and a screw portion of the bolt is caulked and fixed inside the bundle body, When the operation member is rotated in one direction, the floor support plate is raised, and when the operation member is rotated in the other direction, the floor support plate is lowered.

  With such a configuration, the height of the floor plate is adjusted by operating the operation member integrated on the upper part of the bundle body from above (on the floor) the floor support plate to displace the floor support plate up and down. Can do. Therefore, underfloor work with poor workability can be eliminated, and the height of the building can be suppressed by setting the space between the installation surface (foundation) and the floor board to the minimum necessary level. .

Floor plate support of the present invention, the operation member that is integrated into the top of the bundle body, since by operating from above the floor support plate can be displaced on the floor support plates vertically from the floor of the floor plate height Can be adjusted. Therefore, underfloor work with poor workability can be eliminated, and the height of the building can be suppressed by setting the space between the installation surface (foundation) and the floor board to the minimum necessary level. .
