Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a positioning adjuster used for positioning a floor base material at a predetermined height position on a concrete floor surface, for example, so as to be horizontal. The present invention also relates to a method of positioning a floor base material using this adjuster.

[0002]

2. Description of the Related Art The work of laying a floor base material on a concrete floor is generally performed by the following method. That is, this is a so-called double floor method in which a large number of support legs are erected on the concrete floor surface, a floor base material is placed on the support legs, and the support legs are fixed to the support legs with nails or the like. Here, the support leg has a lower end side which is a support rubber part to be installed on the concrete floor surface, and an upper end side which is a head made of special plywood with a size of about 100 mm square, and these are connected by a support bolt part. It has a different structure. When placing the floor base material on the head of this support leg, it is about 10 to 30 m on average.
I am trying to open a gap of m. After laying the floor base material with such a gap, rotate the support bolts to adjust the height of each support leg so that the floor base material becomes horizontal at a predetermined height position from the floor surface. Is being adjusted.

[0003]

However, in this method, after the support legs are installed on the floor surface, it is necessary to first level the heads of the support legs. Furthermore, even after placing the floor base material, adjust the bolts of each support leg,
It is necessary to level the floor base material. 2 like this
The work is time consuming and inefficient because it requires step adjustments. In addition to this, when the gap between the head of the support leg and the floor base material remains as it is, it is necessary to lay the floor base material after placing a thin plywood called discard veneer here. Therefore, workability is also poor in this respect.

An object of the present invention is to pay attention to such a conventional problem, and a positioning adjuster capable of easily setting a floor base material to a predetermined height position on the floor surface in a short time. Is to propose. Another object of the present invention is to propose a method for positioning a floor base material using this positioning adjuster.

[0005]

In order to solve the above problems, the present invention uses a positioning adjuster having the following construction to position a floor base material. That is, the positioning adjuster of the present invention, a bolt member having a position adjusting male screw portion formed on the outer peripheral surface, and a female screw portion that is screwed to the position adjusting male screw portion is formed on the inner peripheral surface,
The basic components are a nut member that is screwed onto the outer periphery of the bolt member, and a nail support member that is rotatably and detachably attached to the tip of the bolt member.

The bolt member has a structure in which a through hole for introducing the tip of the nailing machine is formed in the inside thereof, and an adjusting handle portion for rotating the bolt member is formed at the base end side. There is.

In addition, the nut member has a male screw portion which can be detachably screwed into a hole formed in the floor base material on the outer peripheral surface thereof, and which contacts the surface of the floor base material. It has a structure in which a flange portion in contact with the handle portion is attached and detached for rotating the nut member.

Next, the above-mentioned nail support member is configured to support the nail in such a manner that the tip end side of the leg portion thereof projects from the tip end in the axial direction of the bolt member.

Positioning of the floor base material using the positioning adjuster having this structure can be performed by the following procedure. First, the positioning adjuster supporting the nail is screwed into the mounting hole of the floor base material so that the flange portion of the nut member abuts the surface of the floor base material. Next, the floor base material is installed on the floor surface, and the nails supported by the positioning adjuster are driven by the nailing machine using the through holes of the positioning adjuster to drive the floor base material. Is temporarily fixed to the floor.

Then, the adjustment handle portion of the positioning adjuster mounted on the temporarily fixed floor base material is rotated to adjust the height position of the floor base material from the floor surface. That is, when the adjusting handle portion is rotated, the side of the bolt member relatively moves in the axial direction with respect to the nut member fixed to the floor base material. However, since the tip of the bolt member is fixed on the floor surface by the nail, the side of the bolt member does not move. Therefore, since the nut member fixed to the floor base material moves together with the floor base material, the height of the floor base material with respect to the floor surface is adjusted.
