Description

[Detailed description of the invention] The present invention relates to support legs for raised floors used for flooring to make floors on which precision equipment such as electronic computers, telephone exchanges, automatic control equipment, etc. are installed earthquake-resistant. .

Raised flooring is achieved by placing a number of support legs upright on a concrete slab, leveling the upper parts, and then arranging the floorboards one by one with their corners butted against each other, with the support legs supporting the bottom of each corner. This is a structure that allows many proposals to be made in the past.

The inventors of the present invention have also previously proposed improved support legs mainly for support columns and floor plate receivers in Japanese Utility Model Application No. 55-3675.

Furthermore, Japanese Utility Model Application No. 52-66325 has been proposed as a technique similar to the present invention.

However, the present invention mainly improves the base plate to develop a structure that uses fewer parts, is highly rigid, and is easy to handle.It has strength not found in the prior art and is easy to assemble. ing.

The feature of this invention is that in the support leg consisting of a base plate, a column, and a floor plate holder, the base plate is an independent plate separated from the column, and the base plate has a lower plate with a column fitting projection in the center and The upper plate is integrally formed with a top plate having joint fitting mounting protrusions extending from the support pipe fitting hole in all directions, and bolt holes are provided on the sides of the joint fitting mounting protrusions.

This will be explained in detail below with reference to the drawings.

The drawings show one embodiment of the present invention, and FIG. 1 is a plan view, FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 3 is a side view showing the state of use.

As seen in these figures, the raised floor
The supporting legs are made up of a base plate 1, a support column 2, and a floor plate support 3, and a large number of base plates 1 are integrally connected in all directions with joint fittings 4 as described later to create an earthquake-resistant structure. The structure is such that four floor plates 5 are arranged one after another so that their corners abut against each other to form a floor.

The support legs for the raised floor have an earthquake-resistant structure to protect computers and the like, so they need to have high rigidity, but they also need to be easy to handle during construction.

In addition, the fewer parts are used, the cheaper the product is, the easier it is to construct, and the easier it is to transport.

Therefore, in the present invention, the base plate 1 is an independent plate that is separated from the support 2 (that is, it is not fixed together by welding or the like, but is detachable), and the support pipe fitting hole 6 and the support pipe fitting protrusion 9 are formed during construction. It has a structure that is easy to assemble and handle as it is made to stand up by inserting a support between them.

This base plate 1 has a structure that has never been seen before, and the rigidity of the upper plate 7 and lower plate 8 stacked on top of each other is extraordinary.

The lower plate 8 is a pressed substantially square flat plate with a support pipe fitting protrusion 9 protruding from the center thereof.

A support pipe fitting hole 6 is bored in the center of the upper plate 7, and joint fitting mounting protrusions 10 are provided on each of the four sides around the support pipe fitting hole 10.

Furthermore, a bolt hole 1 is provided on the side surface of the joint fitting mounting protrusion 10.
1 is provided to enable the joint fitting 4 to be mounted with screws.

The free access floor support legs having the above structure are arranged on the floor slab 12 at equal intervals, and the joint fittings 4 are fixed on all sides with bolts 13 to integrally fix the support legs.

Then, fix the whole thing to the floor slab with adhesive.

Holes 14 provided on all sides of the base plate 1 are adhesive escape holes.

Moreover, if the cross-sectional shape of the joint fitting 4 is made bat-shaped and an adhesive layer 15 is formed in the gap between both edges thereof and the floor slab 12, the earthquake resistance is further improved.

As another embodiment of the support leg for a free access floor according to the present invention (not shown here), a joint rod insertion hole is bored in the upper part of the joint metal fitting mounting projection 10 described above, and each The support legs are connected by a joint rod with bent ends in a hook shape, or the screw holes provided in the base plate of each support leg are connected by a joint threaded rod with threaded ends. Can be mentioned.

Furthermore, a large number of bolts are fixed upright in a cross-shaped arrangement on the lower plate of the base plate, and an upper plate with a large number of cross-shaped holes is fitted into this, and at this time, the joint fittings are inserted at the same time. It is also convenient to have a structure in which bolts are bolted together on all four sides, as this invention and purpose are closely matched.

Since the present invention has the structure described in detail above, the base plate does not need to be separated from the support column to be bulky for transportation and storage, and the support for the support support for the support support and the joint fitting attachment part are formed on the base plate itself, so that the joint can be attached in all directions. There is no need to prepare separate metal fittings, and since these are integrated, it is easy to manufacture, easy to assemble, and has high rigidity and excellent strength.
