Description

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

Conventionally, when providing an opening edge on a floor surface, it has been common practice to attach the edge frame material forming the opening edge to a support body erected on the foundation floor surface. However, in this case, 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.

The present invention has been made in order to deal with such conventional problems, and includes a support material interposed between the edge frame material and the supporting body, and the edge frame material is placed and supported on this support material.
To easily adjust the positional relationship between a support and an edge frame material by providing a height-adjustable support on the support, and to easily support the edge frame relative to the support. With the goal.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In the figure, reference numeral 1 denotes supports such as threaded rods that are vertically set up on a pedestal 3 fixed to a foundation floor 2 and are height-adjustable, and are provided at appropriate intervals below the position where the edge of the floor opening is formed. Reference numeral 4 denotes a supporting member having a substantially ⊂-shaped cross section, and one supporting member 4 can be attached to each of the supports 1. More specifically, the support member 4 has bolts 7 on both left and right ends of the upper plate portion 5 for fixing the elongated edge frame member 6 that rests on the support member 4.
An opening 8 having a width slightly larger than the width of the outer diameter of the male threaded portion 7a and a hole 9 connected to this opening 8 and having a width larger than the width of this opening 8 are formed, and these openings 8 The holes 9 are formed at different positions in the left and right directions. Reference numeral 10 denotes an upper plate part that is parallel to the upper plate part 5 but is formed so as to face approximately the center of the upper plate part 5. In the center of the upper plate part 10, a long hole 11 is formed from the edge to the front and back. It is formed in the direction. Reference numeral 12 designates a rear plate portion, and a support portion 13 having an upper edge located slightly below the upper surface of the upper plate portion 5 is provided at an interval A on the outer side of the rear plate portion 12.
The support member 4 having such a configuration has the elongated hole 11 connected to the support member 1.
into the upper end male threaded portion 1a of the nut 14,1.
4, it is attached so that its vertical and longitudinal positions can be adjusted. By the way, the edge frame material 6 has a stepped part 16 into which the lid 15 is fitted and placed, and two grooves along the longitudinal direction into which the head 7b of the bolt 7 is slidably fitted at the lower part. 17, 17 are arranged side by side with their lower ends opened, and this edge frame material 6 is placed such that the forming portions of the two grooves 17, 17 are located on the upper plate portion 5 of the support material 4. and bolt 7
The front and rear positions and the left and right positions can be freely adjusted using the nuts 28 and 28. For details, see the groove 1
The bolt 7 has engaging portions 19, 19 on the inside of the lower ends thereof, and the head 7b of the bolt 7 is formed into a rectangular planar shape (or a parallelogram planar shape), and the bolt 7 has a head 7b formed in a planar shape of a rectangle (or a planar shape of a parallelogram). The interval B between the sides is formed to be approximately the same as the width of the outer diameter of the male threaded portion 7a, and the widths of the opening 8 and the groove 17 are made slightly larger than the interval B. Therefore, when attaching the edge frame member 6 to the support member 4, one of the grooves 17, 17 is aligned with the opening 8 and the hole 9 on one end side of the upper plate portion 5, and the other is attached to the upper plate portion 5. Align the head 7b of the bolt 7 with the opening 8 and hole 9 on the other end side.
from below both ends of the support member 4, respectively, into the grooves 17, 17.
and rotate the bolt 7 approximately 180 degrees so that both ends of the head 7b engage with the engaging portion 19 at the position of the hole 9, and adjust the position of the edge frame member 6 with respect to the support member 4. Then, insert the nut 18 from below the bolt 7 onto the male threaded portion 7a via the washer 20.
are screwed together to fix the edge frame material 6 on the support material 4. Reference numeral 21 denotes a storage box having a channel-like cross section, and a bent piece 22 is formed at the upper end thereof to be engaged with the support portion 13 of the support member 4 and inserted into the space A.

In FIG. 1, the edge frame material 6 is attached on the support material 4,
The lid 15 is shown fitted onto the stepped portion 16 of the edge frame material 6, and the edge frame material 6 is received on the supports 4 located at appropriate intervals.

By the way, in the above embodiment, the openings 8 and the holes 9 are formed at both ends of the upper plate part 5 of the support member 4, but instead of the openings 8 and holes 9, the openings 8 and the holes 9 are formed closer to the center than both ends of the upper plate part 5. These openings 8 and holes 9 are located closer to each other.
A hole having a similar shape may be formed.

The floor opening edge structure of the present invention can be implemented as described above. Supports are provided on each of the supporting bodies erected at appropriate intervals, and the height of the edge frame can be adjusted freely. can be placed and supported, and the position of the edge frame material can be easily adjusted via the support material,
Furthermore, the support of the edge frame member relative to the support member can be carried out extremely easily by means of bolts that are fitted into grooves of the edge frame member through openings on both ends of the support member and nuts that are screwed into the bolts.
