Abstract

(57) [Summary] [Purpose] To provide a high-floor double-floor prop that can be stably supported without buckling even if the floor height becomes high. [Structure] A threaded rod 14 erected on the upper surface of a base 11 and a threaded rod 15 erected on the back surface of a fixing member 12 under the floor are screwed into a sleeve 13 from opposite ends thereof in a reverse screw relationship with each other, and the sleeve 13 Is rotated in one direction so that the base 11 and the fixing member 12 are simultaneously extended or retracted.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a high-floor double-floor column such as a floor of a computer room.

[0002]

[Prior art]

 Generally, double-floor stanchions such as computer rooms have the function of adjusting the level of upper floor materials from the viewpoint of the stability of computers and automation equipment installed on the floor, and further, Even if an external force such as an earthquake is received, it is required that the installation condition of the support columns does not become unstable.

Conventionally, a double-floor column such as a floor in a computer room is usually constructed by screwing a nut 3 into a height adjusting screw rod 2 erected on a base 1 as shown in FIG. The upper floor material 5 is attached to the upper end of the sleeve 4 placed on the upper surface of the nut 3 (Japanese Patent Laid-Open No. 4-228766).

[0004]

[Problems to be solved by the device]

 However, although the above-mentioned conventional columns can provide stable support when the floor height is relatively low, the support becomes unstable when the floor height is 30 cm or more. That is, as shown in FIG. 3, when the floor height increases, the overlapping area between the height adjusting screw rod 2 and the sleeve 4 fitted thereto is reduced in proportion to the height, and the inner surface of the sleeve 4 and the screw rod 2 are reduced. A gap is likely to be created between the column and the column, and the column as a whole is loose, and when the floor height is 30 cm or more, the column is unstable and easily buckled.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a high-floor double-floor floor that can be stably supported without buckling even when the floor height is relatively high. The purpose is to provide support.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the stilt of the high floor type double floor of the present invention is configured such that the rising member from the base and the falling member from the fixing member under the floor are formed as screw rods. At the same time, both screw rods are screwed from both ends of the sleeve into the sleeve holes in which thread grooves having different screw directions are engraved on the inner surface with the center as a boundary, and the sleeve is rotated in one direction. The fixing member is configured to extend or retract at the same time.

[0007]

[Action]

 The high-floor double-floor prop of the present invention is a so-called turnbuckle type connection in which the threaded rod of the base and the threaded rod of the fixing member are screwed from both ends of the sleeve in a reverse screw relationship with each other. . Therefore, even if the floor height becomes high, the contact area between the two threaded rods and the inner surface of the sleeve can be made large, and the stability of the column is high.

[0008]

【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 of a computer room, b is a base material for the floor, 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 pillar 10 connects the base 11 arranged on the base floor surface c in the same manner as in FIG. 2, the fixing member 12 attached to the lower surface of the floor assembly base material b of the upper floor material 5, and the both. It has a configuration in which it is combined with the sleeve 13.

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.

Since the sleeve 13 is configured as described above, 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 beyond 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 if the floor height is 30 cm or more, the stability of the support column 10 can be favorably maintained. When the sleeve 13 is rotated in the opposite direction, the base 11 and the fixing member 12 can be retracted to the sleeve 13 side.

[0013]

[Effect of device]

 As described above, in the high floor type double floor strut of the present invention, the screw rod of the base and the screw rod of the fixing member are screwed from both ends of the sleeve in a reverse screw relationship with each other, so-called turnbuckle type connection. Therefore, even if the floor height becomes high, the contact area between the screw rods and the inner surface of the sleeve can be made large, and the stability of the column can be maintained high.
