2. Description of the Related Art Generally, a plurality of floors are provided between a ground floor and a ground in order to support a floor of a building during construction. Conventionally, as a construction structure of this flooring, conventionally, a flooring formed by cutting wood into appropriate lengths is used to support between a concrete block provided on the ground and large-scale pulling, and an upper end side portion of the flooring. A method has been adopted in which the sculpture and the floor are fixed with a rag, etc., and the floors are connected to each other with a plate material called a root stake to prevent the floor from being slid.

[0003]

However, in the flooring of the conventional structure as described above, the length of the wood is cut exactly according to the distance between the large block and the concrete block, and the floor is thereby cut. However, there is a problem that the construction work is complicated because the troublesome work of forming the slab is required.

[0004] Further, due to the slight displacement of the space between the concrete block and the large pull at the mounting portion of each floor, or the slight displacement of the length at the time of floor cutting or cutting, the floor is largely pulled or the concrete block is displaced. Or if there is no obstacle at the time of construction, after that, when the contraction or distortion occurs in the pulling etc. and the distance between the pulling and the concrete block changes However, there is a problem that the floor is floated and a gap is formed between the floor and the concrete block, and there is a possibility that the building may be distorted or the floor may make noise.

[0005] The present invention has been made in view of the above points,
An object of the present invention is to provide a floor covering that can be easily adjusted in height and has excellent workability.

[0006]

According to the present invention, a threaded bar having a seat is supported on an upper end of a cylindrical body by a threaded bar supporting member screwed to the threaded bar, and a cap member is provided. Is attached to the cylinder so that the support member is rotatable in a gap surrounded by the cap member and the cylinder.

A receiving seat 7 for receiving a reclining member such as 0 is provided by appropriate means such as welding, and the screw rod support member 3 and the fastening member 11 are screwed.

In the present invention, the support member 3 is provided as shown in FIG.
As shown in (a), on a disk-shaped member having a diameter r equal to or smaller than the outer diameter R of the cylindrical body 5 and equal to or larger than the inner diameter R ′ (R ≦ r ≦ R ′), the periphery of the member protrudes and a flange 4 is formed. And a screw hole 12 for screwing with the screw rod 2 at the center thereof. The support member 3 is placed on the upper end of the cylindrical body 5 by the flange 4, whereby the screw rod 2 is supported by the cylindrical body 5.

Further, in the floor covering 1 of the present invention, the cap member 6 having the insertion hole 13 smaller in diameter than the flange 4 of the support member 3 mounts the support member 3 on the upper end of the cylindrical body 5 by appropriate means such as welding. The support member 3 is attached to the cylinder 5 in a state where the support member 3 is placed, and is configured to be able to rotate the support member 3 in a gap S surrounded by the cap member 6 and the cylinder 5 (FIG. 2). .

A fastening member 11 screwed to the screw rod 2 together with the support member 3 covers the support member 3 protruding from the insertion hole 13 of the cap member 6 as shown in the figure, and has a lower end. It is formed in a skirt shape so as to be able to contact the cap member 6.

The floor 1 of the present invention has a height of the seat 7 (ie,
The height of the floor is adjusted to an appropriate height, and the screw rod 2 is inserted into the screw rod insertion hole 19 formed in the large pull 20, as shown in FIG. Seat 7 from the side
From the upper surface side of the large puller 20, the cylindrical nut 9 is fastened to the upper end of the screw rod 2 via a dish-shaped sinking washer 10 to fix the large puller 20 to the floor or 1. It is to support. At this time, if the receiving seat 7 is formed in a cup shape as shown in the drawing, the peripheral edge of the receiving seat 7 is fixed in a state of being sunk into the wood (large pulling 20), so that the wood becomes thin after the operation. However, it is preferable because there is no slack between the seat 7 and the floor noise.

On the outer surface of the bottom of the sink washer 10,
A cutting blade (not shown) is provided, and when the sink washer 10 rotates, the large pulling 20 is cut, and the sinking washer 10 is provided so as to sink while biting into the large pulling 20. At the bottom of the sinking washer 10, an insertion hole 14 for the cylindrical nut 9 is formed. On the other hand, the cylindrical nut 9 is configured so that it can be screwed onto the screw rod 2, and a flange 15 having a diameter larger than the diameter of the insertion hole 14 of the sinking washer 10 is provided on the periphery of the upper end.
