Abstract

PURPOSE:To adjust the height of a new built floor with good working easiness by fitting a male thread part of an adjuster bolt arranged between the existing floor and this new built floor, into a female threaded hole provided in the new built floor, and applying rotating operation from the top. CONSTITUTION:A new built floor 4 is placed on the existing floor 1 of a bathroom and provided with a female threaded hole 6 penetrating vertically. The basis 2 of an adjuster bolt A is placed on the existing floor 1, and male thread part 3 is fitted into the female threaded hole 6 in the new floor 4. The height of new floor 4 is adjusted by operating from above a rotating operation part 7 installed at the top of this male thread part 3, followed by fixation and fast installation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a structure for installing a new bathroom floor without destroying the existing bathroom floor, such as a tile floor.

[Prior art 1] In recent years, it has become common to construct a new bathroom floor without destroying the existing bathroom floor. In this case, as shown in FIG. 4, the base 2 of the adjuster bolt A' is placed on the floor 1, such as the existing tile floor of the bathroom, and the base 2 of the adjuster bolt A' is placed on the new bathroom floor 4 placed on the floor 1. The male threaded portion 3 of the bathroom floor 4 is screwed together, and the bathroom floor 4 can be installed by adjusting the height by rotating the adjuster bolt A'. In this figure, 5 is the floor of the bathroom, and 6 is the bottom of the door frame to which the bathroom door is attached.

[Problem to be Solved by the Invention 1] If the new bathroom floor 4 is installed in this way, the new bathroom floor 4 can be removed without destroying the existing floor 1, but the adjuster bolts A' Because the height is adjusted by rotation between the floor 4 and the floor 1, it is necessary to provide a gap to put your hands in. The problem was that it could be even higher.

The present invention has been made in view of the above points, and an object of the present invention is to enable rotational operation of the male threaded part of the adjuster bolt from above the newly installed bathroom floor, and to increase the height of the bathroom floor. Bathroom floor installations are designed to provide a structure that can be constructed without causing problems.

1 Means for solving the problem 1 To achieve the above object, the structure of installing the bathroom floor of the present invention is that a new bathroom floor 4 is placed on the existing bathroom floor 1, and upper and lower floors are placed on the new bathroom floor 4. The pedestal 2 of the adjuster bolt A is placed on the existing floor 1, and the male threaded part 3 of the adjuster bolt A is inserted into the female threaded hole 6.
A rotation operation part 7 is provided at the upper end of the male threaded part 3 to rotate the male threaded part 3 together with the base 2.

1 Effect] The height can be adjusted by rotating the adjuster pole (A) by operating the one-turn operation part 7 with a tool or the like from above the bathroom floor 4.

[Example] A newly constructed bathroom floor 4 is made of a material such as F'RP as shown in FIG. It is attached as one piece. A female threaded hole 6 is bored in a suitable place in the bathroom floor 4 so as to pass through the bathroom floor 4 vertically. In this embodiment, the female threaded hole 6 is formed by attaching the female threaded cylinder B to the bathroom floor 4. The adjuster bolt A is formed by protruding a male threaded portion 3 from the center of a disc-shaped pedestal 2. This adjuster bolt A' has a male threaded portion 3 lower in height than the conventional adjuster bolt A'. A hexagonal hole 7a is recessed into the upper surface of the male threaded portion 3 of the adjuster pole A as a rotary operation portion 7. A plurality of through holes 10 are perforated in the pedestal 2 of Adjuster Pol) A so as to pass through it vertically, and a strip 1 consisting of a groove or a protrusion is spirally formed on the outer periphery of the pedestal 2. . A is attached to the bathroom floor 4 by screwing the male threaded part 3 into the female threaded hole 6. Therefore, when constructing a new bathroom floor 4 on a floor 1 such as an existing tile floor in a bathroom, the new bathroom floor 4 is placed on the existing floor 1 and the pedestal 2 is placed on the floor 1. .

In this state, use a tool such as a hexagonal wrench as the rotating operation part 7 and fit it into the hexagonal hole 7a, and rotate the male threaded part 3 to rotate the bathroom floor 4.
Adjust the height. Then, the decorative lid 13 is screwed into the female screw hole 6 from the upper surface of the bathroom floor 4 to close the female screw hole 6. Also, when installing the bathroom floor 4, in order to fix the bathroom floor 4 so that it does not move, the pedestal 2 of Adjuster Pol) A is glued to the floor 1, but the adhesive is applied at the position where the pedestal 2 will be placed when the bathroom floor 4 is attached. It is dripped onto the floor 1 in a mountain shape, placed on the pedestal 2, and allowed to harden after a predetermined period of time to adhere. At this time, since the pedestal 2 has a through hole 10, when the pedestal 2 is installed, the adhesive overflows from the through hole 10, and the adhesive flows to the through hole 10 and is firmly fixed. In addition, since the base 2 has the striped portion 1], when the adjuster pole A is rotated and adjusted, the adhesive is caught in the striped portion 1], thereby making it possible to fix the adhesive even more reliably.

[Effects of the Invention] As described above, the present invention provides a female threaded hole penetrating vertically in a newly constructed bathroom floor, places the base of the adjuster bolt on the existing floor, and screws the male threaded portion of the adjuster bolt into the female threaded hole. However, since a rotation operation part is provided at the upper end of the male thread part to rotate the male thread part together with the pedestal, the male thread part can be rotated by operating the rotation operation part with a tool etc. from the top of the bathroom floor. The height can be adjusted, so it can be installed without creating a gap between the existing floor and the bathroom floor, and the new bathroom floor can be installed lower. The floor will not be higher than the bathroom floor, and it can be constructed even if there is a small difference in level between the existing floor and the bathroom floor.
