Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor material supporting leg (so-called floor panel supporting leg) for supporting a floor panel in a state of being floated from a floor surface.

[0002]

2. Description of the Related Art Normally, as a procedure for constructing a free access floor using an independent type support leg, the support leg is temporarily placed on the floor on which the ink has been marked, and the height of the support leg is adjusted. After adjusting the height, the support legs and the floor are fixed with adhesive or concrete studs, and the panels are laid. The height adjustment of these support legs is generally performed using a transit. However, adjusting the height of the support leg using the transit is complicated and time-consuming. For this reason, at the construction site, the height of the support legs is adjusted at regular intervals by the transit, and an aluminum square pipe is passed over the height-adjusted support leg receiving pan. Based on the aluminum square pipe, the height of the support legs between the rows passing the aluminum square pipe is adjusted.

[Problems to be solved by the invention]

[0003] However, the independent type support leg is formed by screwing a tray cylindrical portion having an internal thread formed on the inner peripheral surface and a support column having an external thread formed on the outer peripheral surface. It is necessary to rotate the part. The pitch of the screw formed on the receiving cylinder portion and the column is set so that the receiving portion moves vertically by 1 to 2 mm per rotation so that the height can be finely adjusted. For this reason, when adjusting the height of the support legs based on the aluminum square pipe, if the pan is several tens of millimeters away from the reference height, the pan must be rotated dozens of times. This was causing a decrease in efficiency. Also, since the pan must be rotated to adjust the height, the panel cannot be adjusted while the panel is placed on the support leg pan. The height cannot be adjusted in the state. For this reason, when the panels are laid, rattling occurs, and when the height of the support legs needs to be adjusted again, the heavy panels must be removed, resulting in poor work efficiency.

For this reason, in order to enable the height of the support legs to be adjusted while the panel is mounted, female threads are not formed on the inner peripheral surface of the tray cylinder, but female threads are formed on the inner peripheral surface below the tray portion. There is a method of adjusting the height by screwing a nut to a support and rotating the nut. However, in this method, if the pan is tens of millimeters away from the reference height, the pan must be rotated dozens of times,
There is a problem that the operation is complicated because the fixing bolts are two nuts and the receiving portion.

[0005] The present invention has been made in view of such problems, and it is possible to easily adjust the height without rotating the tray, and to fix the fixing device in order to reduce the construction time. An object of the present invention is to provide a floor panel supporting leg which has a single bolt, is easily finely adjusted, and has an excellent load bearing capacity.

[0006]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, completed the present invention.

That is, the present invention provides (1) a floor panel supporting leg having a substrate 1, a column 2 which is vertically bonded to the substrate 1 and has an external thread formed on the outer peripheral surface, and a cylindrical receiving cylinder portion 5 above the column 2. The semi-cylindrical fixing part 5 ′ provided at the lower part of the pan cylinder part 5 and the semi-cylindrical fixing part 5 ′ can be opened and closed by being connected with the hinge 6, A semi-cylindrical metal fitting 3 having a female screw formed on the inner peripheral surface thereof is provided at an end of the metal fitting 3 after height adjustment is performed by sliding the tray cylinder 5 to a predetermined height. The column 2 and the metal fitting 3 can be screwed together by screwing the bolt 4 into the locking hole 5a having a female screw formed on the inner peripheral surface provided at the end of the hole 3a and the fixing portion 5 '. The present invention relates to a floor panel support leg.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION

[0009]

According to the support leg of the present invention, the pan can be moved up and down without rotating the support leg pan, so that the height adjustment operation is simplified and the construction time can be shortened. In addition, the height can be adjusted even when the panel is placed on the support leg receiving portion.

Further, since the female screw is formed on the inner peripheral surface of the metal fitting 3, the bolt 3 is screwed into the locking hole 5a through the hole 3a having the female screw formed on the internal circumferential surface, and the metal fitting 3 is temporarily fixed.
By rotating, fine adjustment of the height can be easily performed. Further, since the load applied to the receiving tray is supported by the female screw on the inner peripheral surface of the metal fitting 3, the bearing has a load resistance equivalent to that of a conventional supporting leg in which a female screw is formed on the inner peripheral surface of the receiving drum.

The length of the inner periphery of the fixed portion 5 'is
Are cut so as to be shorter than a half circumference of the outer peripheral surface, and when the metal fitting 3 is screwed into the support 2, the metal fitting 3 b and the metal fitting 5 b are separated. For this reason, the bolt 4 is screwed into the locking hole 5a through the hole 3a, and the metal fitting 3 is screwed into the column 2, and the receiving cylinder portion 5 and the column 2
The state in which the tray part 5 can be freely moved up and down without screwing, the state in which the tray part 5 can be freely rotated by screwing, and the state in which the tray cylinder part 5 is fixed because it is screwed and pressed are arbitrarily selected. You can do it. From this, the support leg 1
The number of tightening screws required per unit is one, and the installation time is shorter than the conventional type, which required two screws, a conventional fixing screw for the vertical adjustment nut and a rotation fixing screw for the pan. Be shorter. Further, since the rotation of the tray 5 can be adjusted in a fixed state, the construction is simple and the time required for the adjustment is short.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a support leg according to the present invention.

Embodiment 1 In the support leg of the present invention, first, the substrate 1 is temporarily installed at a predetermined position on a floor base such as a concrete slab, and then the tray portion cylindrical portion 5 is inserted into the column 2. In this state, the supporting legs are temporarily placed along the black line of the floor slab. Next, the height is adjusted using a transit at a fixed angle between rows according to the length of the aluminum square pipe to be used. For height adjustment, after the tray portion is slid to a predetermined approximate height, the metal fitting 3 is closed and screwed to the support column 2. Next, the bolt 4 is screwed into the locking hole 5a through the hole 3a. At this time, the bolts 4 are tightened so that the tray portion can be rotated. Next, while checking the height by the transit, the tray portion screwed to the column 2 is rotated to perform fine adjustment. After the height adjustment, the bolt 4 is further tightened to prevent the rotation of the tray and the backlash.

Next, an aluminum square pipe is passed over the tray of the support leg, the height of which has been adjusted at regular row intervals. The height of the support leg, which is temporarily placed between the support legs whose height has been adjusted using the aluminum square pipe as the height reference, is slid up and down to adjust the height. After the receiving portion is adjusted to a predetermined height, the metal fitting 3 is screwed to the column 2, and the bolt 4 is screwed into the hole 5a through the hole 3a. At this time, the bolt 4 is tightened until the pan does not rotate and there is no backlash.

After adjusting the height of the supporting legs, an adhesive is applied to the supporting leg substrate 1 to fix the floor slab and the supporting legs.
Next, the panel is laid along the panel positioning claws 9. Check the rattling of the panel at the same time as laying the panel. If rattling occurs, bolts 4
And fine-adjust the height of the pan. After adjusting the height so that the panel does not rattle, the bolt 4 is tightened and fixed by a screwdriver.

[0016]

According to the floor panel supporting leg of the present invention, the height can be adjusted without rotating the tray, so that the floor panel can be easily formed in a short time. In addition, since the height can be adjusted without rotating the pan, the height can be adjusted with the panel mounted. Further, since the receiving portion can be fixed according to the amount of the bolt 4 to be tightened, only one bolt is required. For this reason, simplification of construction and shortening of construction time can be achieved.
