[Industrial applications]

 The present invention relates to a floor board supporting device for supporting a finished floor board stretched as a double floor on a structural floor of a concrete building or the like.

[0002]

[Prior Art]

 Conventionally, in the case of forming a double floor on a structural floor such as a concrete structure, joists or large lumbers have been laid on the structural floor, and a finishing floorboard has been placed on it. Such a double floor formation method requires complicated work and requires skilled workers because it is difficult to secure the horizontalness of the finished floor boards.

[0003] In order to eliminate such drawbacks, so that even a non-skilled worker can carry out double-floor construction, the joists and large lumbers laid on the structural floor are eliminated, and the finished floor board is directly supported by the pedestal. There is proposed a floor plate supporting device, for example, a floor plate supporting device as described in Japanese Utility Model Publication No. 60-6107. This conventional floor board supporting device will be described with reference to FIG.

FIG. 12 is a sectional view of a conventional floor board supporting device. The conventional floor board supporting device A includes an adjusting male screw cylinder 101 having upper and lower male screws opposite to each other and a female screw hole 102a screwed into an upper male screw 101a of the adjusting male screw cylinder 101. It has a floor plate receiving plate 102 to be installed, and a circular base 103 in which a female screw hole 103a to be screwed with the lower male screw 101b of the adjusting male screw cylinder 101 is provided.

A hexagonal engagement hole 101c into which a square bar wrench is inserted is formed in the upper part of the inner surface of the adjusting male screw cylinder 101, and a pin insertion hole 101d into which an L-shaped rotation stop pin 104 is inserted is formed at the upper end of the cylinder. Had been drilled. Further, the floor plate receiving plate 102 is provided with several screw holes 102 b, and the finishing floor plate 105 mounted thereon is fixed by screws 106. Further, a nail hole 103b was formed at the center of the circular base 103, and it was fixed on the structural floor 107 using concrete nails 108.

In the conventional method of using the floor plate supporting device A, first, a mounting hole 105 a of the floor plate supporting device A is formed at a required position of the finishing floor plate 105, and a floor plate receiving plate 102 is provided with a screw 106 on the back surface of the mounting hole 105 a. Then, the upper male screw 101a of the adjusting male screw cylinder 101 is screwed into the female screw hole 102a of the floor plate receiving plate 102, and then the circular base 103 is screwed to the lower male screw 101b of the adjusting male screw cylinder 101. In addition, the floor board supporting device A was attached to the finishing floor board 105. At this time, the circular base 103 was appropriately rotated to adjust the support height H of the finishing floor plate 105 of the floor plate supporting device A.

A finishing floor plate 105 to which the height-adjusted floor plate supporting device A is attached is laid at a predetermined position on the structural floor 107, and the concrete nail 108 is attached from the upper portion of the finishing floor plate 105 using the mounting hole 105a. The finishing floor board 105 and the floor board supporting device A were fixed by driving into the nail holes 103b of the circular base 103. When the fixed finishing floor plate 105 is uneven, a square bar wrench is inserted into the engaging hole 101c of the adjusting male screw cylinder 101 from the mounting hole 105a, and the adjusting male screw cylinder 101 is appropriately rotated. Therefore, the support height H of the finishing floor board 105 was finely adjusted.

After that, the L-shaped detent pin 104 is inserted into the pin insertion hole 101d at the upper end of the adjusting male screw cylinder 101, the blocking plug 109 is inserted into the mounting hole 105a, and the upper side 104a of the detent pin 104 is pressed. However, the rotation stopper pin 104 and the adjusting male screw cylinder 101 are prevented from rotating.

[Problems to be solved by the device]

 However, since the conventional floorboard supporting device A is installed on the finishing floorboard 105 and then laid on the structural floor 107, it is difficult to match the black ink printed on the structural floor 107, and the center of the floorboard supporting device A is displaced. It had a drawback that it would end up.

Further, the support height H of the finishing floor plate 105 is adjusted in advance by appropriately rotating the circular base 103 in advance, but it is not possible to adjust the extension in advance in consideration of the waviness and inclination of the structural floor 107. Since it is difficult, it is necessary to adjust the unevenness after fixing the finishing floor plate 105. However, it is necessary to rotate the adjusting male screw cylinder 101 while the load of the finishing floor board 105 is being loaded, and a great amount of force is required, so the height adjustment is not easy.

Further, although the finishing floor plate 105 is fixed to the floor plate receiving plate 102 by screws, it cannot be re-tightened when the screws 106 are loosened due to vibration or the like, so that the floor plate receiving plate 102 and the finishing floor plate 105 are joined. However, there is a drawback in that the supporting height H is changed due to the rotation of the floor plate receiving plate 102 and that the support of the finishing floor plate 105 is loose.

Further, the rotation of the adjusting male screw cylinder 101 is prevented by pressing the upper side portion 104a of the rotation stop pin 104 with the closing plug 109, but when the closing plug 109 is loosened due to vibration or the like, the adjusting male screw cylinder 101 is rotated. 101 has a drawback that it easily rotates and eventually comes out of the floor board supporting device A 1.

The present invention solves the above-mentioned drawbacks of the conventional floor board supporting device, is accurately aligned with the marking position of the structural floor, and the height can be adjusted precisely and easily, and even after laying the floor board. It is an object of the present invention to provide a floor board supporting device capable of level adjustment.

Another object of the present invention is to provide a floor plate supporting device that can easily manage the joint state between the floor plate and the floor plate supporting device and can reliably prevent rotation, loosening and slipping out of parts of the floor plate supporting device.

[0015]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the floor board supporting device of the present invention has a height adjusting male screw threaded from one end of the shaft and a floor board tightening male screw threaded from the other end of the shaft.
