[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protection device for a double-floor column such as a floor of a computer room, and particularly to an OA (office automation) cable arranged around it.

[0002]

[Prior art]

 Generally, in a double-floor structure such as a computer room, from the viewpoint of the stability of computers and automation equipment installed on the floor, the upper floor material is supported by the columns equipped with its level adjustment mechanism, and OA cables such as communication cables and optical cables are arranged in the double-floor space.

Conventionally, in the level adjusting mechanism of the above-mentioned double floor strut, a nut is screwed into a height adjusting screw rod standing upright on the base, and a sleeve is further fitted to the screw rod to attach the upper surface of the nut. The lower adjustment type adjusts the level of the upper floor material supported by the upper end of the sleeve by moving the nut forward and backward, or it is fixed to the lower surface of the upper floor material 5 as shown in FIG. The height adjusting screw rod 2 is attached to the nut 1 by penetrating engagement with the nut 1, and the screw rod 2 is advanced and retracted from above the upper floor member 5 to adjust the level, which is an upper adjustment type structure.

However, the screw rod of the level adjusting mechanism causes damage to the OA cable wired in the double floor when the double floor is constructed or when electronic devices are replaced. There is.

As a solution to this problem, it has been conventionally known to use a synthetic resin container having a hollow inverted truncated cone shape as a cable protector (Japanese Utility Model Publication No. 1-129343). As shown in FIG. 2, this cable protector includes a plurality of hollow inverted truncated cone-shaped containers 3 stacked below the corner abutting portion of the upper floor member 5 until they come into contact with the upper floor member 5. By surrounding the four height adjusting screw rods 2 which are engaged through the nuts 1 fixed to the material 5 with this laminated container 3, the surrounding OA cable 4 enters the area of this laminated container 3. It was designed so that it would not exist.

[0006]

[Problems to be solved by the device]

 However, in the conventional cable protector described above, in order to adjust its height, a large number of containers 3 must be stacked and used at each corner abutting portion of the upper floor material, which results in manufacturing cost and construction. It is uneconomical on both sides. This problem is particularly noticeable in the case of a high floor type double floor structure having a floor height of 30 cm or more.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an OA cable protection device for a double floor strut that is inexpensive to manufacture and is extremely easy to install. It is in.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, in the OA cable protection device of the present invention, the rising member from the base is formed as a threaded rod, and the height is adjusted by the threaded rod and nuts engaged with the threaded rod. In the support for a heavy floor, a flexible pipe is fitted into the nuts in advance, and the pipe is lowered after the support is installed until it comes into contact with the base.

[0009]

[Action]

 The flexible tube to be fitted in the nuts in advance is, for example, a vinyl tube or the like, and can be obtained at low cost. Further, the construction of this protective pipe is extremely simple as the pipe is lowered until it comes into contact with the base after the support is installed, and the OA cable can be protected from damage by the screw rod by using only one for each support.

The present invention can be applied to any strut in which the rising member from the base is formed as a threaded rod and the height is adjusted by the threaded rod and nuts engaged with the threaded rod. Nuts include not only nuts but also sleeves and the like.

[0011]

【Example】

 Hereinafter, the present invention will be described with reference to the illustrated embodiments.

In FIG. 1, a is a floor panel that constitutes an upper floor material 5 of a double floor in a computer room, b is a floor assembly base material thereof, and c is a concrete foundation floor surface. Numeral 10 is a column which supports between the flooring base material b and the concrete foundation floor surface c.

The support column 10 is formed by combining a base 11 arranged on the base floor surface c, a fixing member 12 attached to the lower surface of the lower floor base material b of the upper floor material 5, and a sleeve 13 connecting the both. It has been configured.

The base 11 has a threaded rod 14 planted in the center of its upper surface as a rising member, and the fixing member 12 has a threaded rod 15 planted in the center of its lower surface as a falling member. Further, on the inner surface of the inner hole 16 of the sleeve 13, screw grooves 17 and 18 having different screw directions from the center are carved from both end sides of the sleeve. The screw rod 14 of the base 11 is screwed into the one screw groove 17, and the screw rod 15 of the fixing member 12 is screwed into the other screw groove 18 from the sleeve end side. That is, the base 11 and the fixing member 12 are screwed into both ends of the sleeve 13 in a reverse screw relationship with each other, and are connected to each other in a so-called turnbuckle manner.

Therefore, when the sleeve 13 is rotated in one direction, both the base 11 and the fixing member 12 extend from the sleeve 13 and the upper floor member 5 can be supported from below. In this case, the amount by which the base 11 and the fixing member 12 extend from the sleeve 13 may be smaller than the length of the sleeve 13, and a large contact area between the screw rods 14 and 15 and the inner surface of the sleeve 13 can be obtained. Even in the case of a high floor with a floor height of 30 cm or more, the stability of the column 10 can be maintained well. When the sleeve 13 is rotated in the opposite direction, the base 11 and the fixing member 12 can be retracted toward the sleeve 13 side.

Further, a flexible tube 19 such as a vinyl tube is fitted in advance around the outer periphery of the lower end of the sleeve 13 as suggested by a chain line. As shown by the solid line, it is lowered until it contacts the base 11. That is, this pipe 19 is a protection pipe for preventing damage to the OA cable 4 arranged in the double floor, and its vertical length can sufficiently cover the maximum diameter of the cable 4. It is a dimension.

In the above embodiment, the pipe 19 is fitted in the sleeve 13 in advance. However, in the case of a strut in which a nut is engaged with a screw rod of the base, the pipe 19 is fitted in the nut in advance. You can leave it.

[0018]

[Effect of device]

 As described above, in the OA cable protection device of the present invention, it is sufficient that the flexible tube is pre-fitted into the nuts of the supporting column and then lowered after contacting the base after the mounting of the supporting column. Can be installed on. Also, since this tube is a vinyl tube or the like, it can be obtained at a low cost, and since only one tube is required for each support, it is extremely economical.
