Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double floor slope forming a part of a double floor so that various wirings can be accommodated under the floor.

[0002]

2. Description of the Related Art Conventionally, a slope, which is an approach portion between a slab and a double floor, has a channel-shaped slope leg whose upper surface is inclined and placed on the slab by a required number at a predetermined interval. , A flat plate and a carpet are placed on the upper surface of the slope leg. Since the height of the double floor is adjusted according to the installation location, it is necessary to adjust the height of the end on the double floor side to the height of the adjusted double floor even for the slope that continues to this. There is. The height of the slope leg is usually adjusted by stacking a required number of thin liners at the installation site.

[0003]

However, when the height is adjusted by the liner as described above, the same work must be performed on each of the plurality of slope legs, and when the flat plate is placed on the slope legs. It could be difficult to stack the liners, and the height of each slope leg may be slightly different, which may cause the surface to wavy or have steps after completion. It was

An object of the present invention is to eliminate such a problem.

[0005]

The present invention takes the following means in order to achieve such an object. That is, the double floor slope according to the present invention changes the height of the slope leg member whose upper surface inclines when placed on a horizontal surface and the height of one end of the slope leg member by the rotation operation. It is characterized by comprising an elevating mechanism.

The lifting mechanism of the present invention includes a base having an internal thread element on the upper portion and an inclined upper part, and a vertical movement to a vertical direction with respect to the female thread element of the base by screwing. It is preferable that the upper and lower members are provided with a groove in the upper tip portion thereof, and a support member that is mounted in the vicinity of the upper tip portion of the lifting and lowering member in parallel with the upper portion of the base, and as the slope leg member, It is preferable that one end portion of the elevating member is supported by a supporting member and has a through hole through which the upper end portion of the elevating member is exposed. The female thread element may be a nut, and the elevating member may be a male thread rod.

[0007]

With this structure, the height of one end of the slope leg member can be changed by rotating the elevating mechanism. That is, when matching the height of the double floor, one end of the lifting mechanism and the slope leg member is installed close to the double floor. Then, the elevating mechanism is operated to make one end of the slope leg member flush with the double floor. Therefore, the height adjustment work is simplified by only the turning operation of the lifting mechanism, and the adjustment range can be increased by setting various lifting ranges of the lifting mechanism.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

A double floor slope SS shown in FIG. 1 has a slope leg member 1 whose upper surface inclines when placed on a horizontal surface and a height of one end 11 of the slope leg member 1. It has an elevating mechanism 2 which is changed by an operation motion.

The slope leg member 1 includes a connecting member 12 mounted on a plurality of unit lifting mechanisms 3, and the connecting member 1 thereof.
2 side view wedge-shaped channel member 13 fixed at a predetermined interval in the direction perpendicular to the longitudinal direction. The connecting member 12 forming one end 11 of the slope leg member 1 is
The upper wall of the channel member is provided with through holes 12a corresponding to the male screw rod bodies 33 as the lifting members of the unit lifting mechanism 3, the upper end portions of which can be exposed. In addition, five wedge-shaped channel members 13 that planarly support the slope are welded and fixed to the front wall at predetermined intervals. This wedge-shaped channel member 1
3 has a wedge shape whose side wall is inclined to match the minimum slope of the slope, one end 13a of which is welded with its upper wall flush with the upper surface of the connecting member 12, and the other end 13b. Are connected by a flat plate 14 so as to be flush with each other. And, after the height adjustment is completed, countersunk holes 15 into which screws for fixing to the slab are inserted are drilled at five positions on the other end 13b. Further, a countersink 12b, which is paired with the through hole 12a of the connecting member 12 and through which a screw is passed when the slope leg member 1 is fixed to the supporting member 35 of each unit lifting mechanism 3, has a countersunk hole 12a which is closer to the through hole 12a. It is provided on the end 11 side.

The elevating mechanism 2 supporting one end of the slope leg member 1 is composed of a flat plate 21 as a base and a plurality of unit elevating mechanisms 3 fixed on the flat plate 21 at predetermined intervals. Each unit elevating mechanism 3 has a nut 31 as an internal thread element on the upper portion and the upper portion is inclined.
2, an external thread rod body 33 as an elevating member in which a groove 34 is provided in an upper tip portion 33a that is screwed into the nut 31 of the base 32 and moves up and down in a direction perpendicular to the upper portion of the base 32, and an external thread rod body. A support member 35 is attached near the upper tip 33 a of the base 33 in parallel with the upper portion of the base 32. In the unit lifting mechanism 3, a base 32 is erected on the flat plate 21 by welding, and the base 3
2, an external thread rod body 33 having a support member 35 fixed near the upper tip portion 33a is screwed and formed. The base 32 has an upper surface wall 32a inclined with respect to the horizontal at an angle of, for example, 7 °.
1 is welded and fixed to the flat plate 21 by welding at a predetermined interval. Fixing holes 22 are formed in the flat plate 21 at both ends thereof and a gap between the bases 32, respectively. The male screw rod body 33 screwed to the base 32 has a groove 34 or a slit having a width into which the tip of a driver can be inserted, formed in the upper tip portion 33a, and a disc from below on the lower side thereof. The supporting member 35 is fixed by welding. The position where the support member 35 is fixed is set to a position separated from the upper end portion 33a of the male screw rod 33 by a distance substantially the same as or slightly smaller than the thickness of the connecting member 12 of the slope leg member 1. When the member 1 is placed, the upper tip 33a is prevented from protruding from the upper surface wall of the member 1. Then, the length of the male screw rod body 33 represents the height adjustment range by the angle formed between the other end 16 of the slope leg member 1 on a horizontal plane and the upper surface of the slope leg member 1. In this case, for example, it may be set so that it can be adjusted within a range of about 3 °, and when the height of the base 32 is increased, it is more advantageous in terms of strength to set it smaller than this.

In the double floor slope SS having such a structure, after the elevating mechanism 2 is placed at a desired position on the slab, the slope leg member 1 is placed on the elevating mechanism 2. The slope plate 4 is placed and installed on the slope leg member 1. First, the lifting mechanism 2 is fixed to a target position with a bolt. Next, the slope leg member 1 is placed on the support member 35 of the elevating mechanism 2 so that the upper tip portion 33a of each male screw rod 33 of the elevating mechanism 2 fits into the through hole 12a of the connecting member 12. Place. In this state, the driver is inserted into the groove 34 of the male screw rod body 33 from the through hole 12a of the slope leg member 1 so that the upper surface of the one end 11 of the slope leg member 1 coincides with the height of the double floor. Adjust by turning the male screw rod body 33. This adjustment is performed for all of the unit lifting mechanisms 3.

When the height adjustment of the slope leg member 1 is completed, a screw hole is drilled from the countersunk hole 12b of the slope leg member 1 to each support member 35, and the slope leg member 1 is fixed to the support member 35 with tapping screws. To do. As a result, the rotation of the male screw rod body 33 is prevented by the slope leg member 1 and the height does not change. This fixation is
In this embodiment, the left and right end portions of the slope leg member 1 and the central three positions are sufficient. In the slope leg member 1 of this embodiment, countersink holes 12 for fixing are provided at five places.
b is provided so that when the width of the slope leg member 1 is reduced, the slope leg member 1 can be easily aligned with the support member 35 of the elevating mechanism 2. When it is cut by cutting, it is possible to easily use the one at an appropriate position. If the width of the construction site is larger than one set of lifting mechanism 2 and slope leg member 1 and less than two sets of width,
The width of one of the sets may be appropriately cut to fit the countersunk hole 12 of the slope leg member 1 and used in combination.

After that, the slope plate 4 is placed on the slope leg member 1, a screw hole is drilled in the slope leg member 1 by a drill in accordance with the countersink hole 41 of the slope plate 4, and the slope is tapped with a tapping screw. Fix the plate 4 to the slope leg member 1,
A slope is formed on which the carpet 5 is not attached. The carpet 5 is attached to the slab side edge of the slope plate 4.
In order to eliminate the step difference at the boundary between the slab and the slab, the edge member 6 made of an aluminum extruded material is attached and the carpet 5 is attached to complete the double floor slope.

As described above, the height of the slope leg member 1 can be continuously adjusted by rotating the male screw rod body 33, and the work of the slope leg member 1 can be performed continuously. Since it is performed from above, it can be performed in a stable working posture. In addition, the base 32 of the unit lifting mechanism 3 in the lifting mechanism 2 is prepared with several types having different heights so that the range adjustable by the male screw rod body 33 is substantially the same. If 3 is formed, when adjusting the height, only the fine adjustment by the male screw rod body 33 is required, so that the workability can be improved and the height adjustment range of the entire product can be expanded. . Moreover, if the male screw rod bodies 33 have the same length, it is possible to simplify inventory management of the parts.

The present invention is not limited to the embodiment described above. In the above-described embodiment, the case of adapting to a relatively wide place has been described, but when the width is narrow, the number of the unit elevating mechanisms 3 is reduced and the widths of the elevating mechanisms 2 and the slope leg members 1 are reduced. do it. In the case of an extremely narrow space, the unit lifting mechanism 3 may be the lifting mechanism 2 independently, and the slope leg member 1 may be a wedge-shaped channel member in side view.

In addition, the configuration of each part is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

[0018]

As described above in detail, according to the present invention, since the height of one end of the slope leg member can be adjusted by the elevating mechanism, the height adjustment work at the construction site is simplified. The construction period can be shortened. Also, if the lifting mechanism is composed of a lifting member that is screwed into the female screw element,
The height can be adjusted simply by rotating the elevating member, and the work can be performed only by the screwdriver used for screwing. Moreover, by using the screw element, the height can be continuously adjusted and the adjustment range can be expanded.
