Description

[Detailed Description of the Invention] The present invention relates to a constituent member of the edge of a floor opening having an underfloor space.

Conventionally, when providing an opening edge on a floor surface, the edge frame material forming the opening edge is usually attached to a support that is erected on the base floor surface.

However, in this method, it is extremely difficult to adjust the positional relationship between the support and the edge frame material, and therefore high precision is required in setting the upright position of the support.

In view of this, the present invention attempts to easily adjust the positional relationship between the support and the edge frame by interposing a support member that supports the edge frame between the support and the support. An embodiment of the present invention will be described below with reference to the drawings. 1 is a support such as a threaded rod that is vertically set up on a pedestal 3 fixed to a foundation floor 2, and 4 has a U-shaped cross section. The upper piece 5 and the lower piece 6 of the supporting material have grooves 7 and 8 formed in the front and back direction from the edge at appropriate positions, and the upper edge is slightly lower than the upper surface of the upper piece 5 on the outside of the vertical piece 9. The supporting parts 10 are provided at intervals of 10', and the lower piece 6
The groove 8 is inserted into the upper part of the support 1, and the support body 1 is attached so that its vertical position and front and back position can be adjusted using a tightening tool 11 such as a nut. 12 forms a stepped portion 14 into which the lid 13 is fitted, and a dovetail groove 17 along the longitudinal direction into which the head 16 of the bolt 15 is slidably fitted is arranged at the bottom with the bottom open. The edge frame material provided is placed on the upper piece 5 of the support member 4, and bolts 15 are inserted into the grooves 7, and nuts 18 are used to adjust the front and rear positions as well as the left and right positions. Reference numeral 19 designates a storage box having a channel-like cross section, and an overhanging piece 21 having a bent piece 20 inserted into the interval 10' of the support member 4 is formed on the edge thereof.

Thus, the supporting members 4 are attached to the supporting members 1 erected at required intervals on the foundation floor surface 2 with the supporting parts 10 facing each other, and the supporting members 4 are attached to each supporting member 1 individually. However, it may also be provided over the entire length of the opening edge.

As mentioned above, the present invention includes a support 1 and an edge frame material 12.
A supporting member 4 is interposed between the edge frame member 12 and a bolt 1 in a dovetail groove 17 provided at the lower part of the edge frame member 12.
5 is slidably attached along the longitudinal direction, and this bolt 15 is inserted into the groove 7 of the support member 4 so that its position can be adjusted in the front-rear direction, that is, in the width direction of the opening edge constituting the edge frame. The position of the member 12 can be easily adjusted with respect to the support member 4 fixed to the support body 1, and the required spacing between the opening edges can be set accurately.

In addition, by arranging the dovetail grooves 17 at the bottom of the edge frame material 12 in parallel, the width of the edge frame material 12 is increased, and the mounting on the support material 4 is made stable. The dovetail groove shape 17 can be used for conversion, thereby increasing the range of position adjustment in the front and rear directions.

Furthermore, since the support member 4 is attached by inserting the support member 1 into the groove 8 formed in the lower piece 6, the support member 4 can also be adjusted in position relative to the support member 1 in the front-rear direction, that is, in the width direction. The supporting members 4 can be installed at required intervals, and the edge frame member 12 can be mounted and attached to the supporting members 4 in a stable state.

Although the embodiment shown in the drawings shows a type in which a storage box 19 is attached, the storage box 19 is not necessarily necessary, and it goes without saying that there are other ways to attach the storage box 19.

As described above, the present invention has the advantage that the positional relationship can be easily adjusted and construction can be performed accurately as a member for constructing an opening edge on a floor surface having an underfloor space.
