Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height adjusting device when a panel is used for a building to form a double floor. The double floor is used when the floor is not flat or has a slope. The purpose of the present invention is to provide a suitable one for leveling the surface.

[0002]

2. Description of the Related Art As a supporting leg for a panel forming a double floor, for example, as seen in Japanese Utility Model Laid-Open No. 58-19038, a height adjusting bolt provided vertically on a base portion of the supporting leg simply serves as a receiving plate. Conventionally, there has been a structure that adjusts the height of the floor, and another structure in which four screw legs are provided as independent adjusting means at the four corners of the floor plate.

[0003]

In the former case, the conventional height adjusting mechanism as described above can adjust the entire height with a large movement amount at a time, but if the ground surface has an inclination or unevenness, Since there is a step between the panels due to the inclination, it is not possible to finely adjust each panel to eliminate the step. In the latter case, the step can be finely adjusted contrary to the former. However, it takes a lot of time to adjust the screw legs of each corner in order to adjust the height of each of the corners, and then the screw legs have to be finely adjusted again.

[0004]

In order to solve the above-mentioned problems, in the present invention, in the height adjusting device for a double floor panel, the main screw portion 3 provided perpendicularly to the base 5 is provided. Is provided and an adjusting screw hole 8 for the fine adjusting screw mechanism 6 is provided near the outer periphery of the receiving plate 2, and the adjusting screw 7 screwed into the adjusting screw hole 8 has a flange portion 14, and this flange The portion 14 is in contact with the bottom surface of the panel 1 and the fall prevention pin portion 12 also serving as a rotation stopper for the pin-shaped receiving plate 2 extended from the flange portion is inserted into the insertion hole 13 provided in the panel corner portion. We have developed a height control device for double floor panels, which is characterized by the following features.

[0005]

With this structure, even if the base of the device is in close contact with the inclined floor material and the supporting legs are in the inclined state, the upper surface of the collar portion 14 that contacts the receiving plate contacts the bottom surface of the panel. 4
Each corner of the abutting portion of the panel can be finely adjusted individually to maintain the levelness. In addition, a pin-shaped drop prevention pin portion 12 provided extending from the flange portion of the adjusting screw 7
However, since it is inserted through the insertion holes provided in the panel corners, it is necessary to prevent the panel from coming off the support legs even when there is excessive vibration due to an earthquake, etc., and especially to prevent loosening of the main screw part and receiving plate. do not do. Since the screw mechanism 6 is on the side of the base 5 and not on the side of the panel 1, it is possible to remove only the panel, and when laying the removed panel again at the time of layout changes or inspections, the return position of the panel can be specified or re-installed. No need for fine height adjustment. Further, since the basic height adjustment, which requires a large amount of movement, is performed by the main screw portion, the adjustment amounts of the four adjusting screws 7 need only be finely adjusted and no labor is required.

【Example】

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view showing the device of the present invention, and FIG. 2 is an exploded perspective view. As can be seen in this example, the device has a base 5
The receiving plate 2 is screwed into and attached to the main screw portion 3 provided perpendicularly to the base, which supports the corners of the four panels abutting each other at the same time and adjusts the height vertically. To do. The receiving plate 2 is provided with a screw mechanism 6 for finely adjusting each corner of the abutting portions of the four panels. That is, a main screw hole 11 into which the main screw portion 3 is screwed into the receiving plate 2 and a screw mechanism 6 for finely adjusting each corner portion of the abutting portions of the four panels near the outer periphery thereof.
Adjustment screw holes 8 are provided. The adjusting screw 7 screwed into the adjusting screw hole 8 has a flange portion 14 that abuts the bottom surface of the panel 1 to directly support the panel, and is a pin-shaped drop prevention pin portion provided extending from the flange portion. 12 is inserted from the back surface into an insertion hole 13 provided in the panel corner portion, and the upper end thereof serves as a tool contact portion 9. This tool contact part 9
Is a shape that fits an adjustment tool such as + or-and a hexagon. Due to the long pin-shaped drop-preventing pin portion 12 provided on the top of the adjusting screw 7, the panel does not come off and fall even if an earthquake or the like occurs. If the adjusting screw 7 has a structure in which a spring is externally inserted and tightened, a rotation preventing effect can be obtained.

[0007]

EFFECTS OF THE INVENTION The height adjusting device for a double floor panel according to the present invention is completed to easily and stably provide the levelness of the double floor surface when the floor is not flat or has a slope. It became possible to. Moreover, the panel can be stably supported against a strong shock or an earthquake. Since the screw mechanism is on the base side and not on the panel side, it is possible to remove only the panel at the time of layout changes or inspections, and it is not necessary to specify the panel return position or readjust the adjusting screw, improving work efficiency. Can be measured.
