のである。[Detailed Description of the Invention] The present invention relates to an improvement of a structure installed as an earthquake-resistant structure on a free access floor plate installed in a computer room, a telephone exchange room, an information processing equipment room, etc.

を払い施工しなければならない。 In the conventional earthquake-resistant structure, as shown in FIGS. 1 to 4, the diagonal members 2 are mainly composed of flat plates, the horizontal connecting members 3 and 3' are made of equilateral angle steel, and bolts 5a to 5c, washers 6a to 6c, and nuts 7a to At 7c, support leg 1
It is screwed and fixed to the support leg 1 through two upper and lower stoppers 4 and 4'. For this reason, the wirings 10a and 10b are easily damaged at the edge portions of the flat plate 2, and as a countermeasure against this, a wiring protection cover 9 or the like is used. For this reason, extreme caution must be taken when wiring work or changes are made.

形鋼を使用しているため送風抵抗が大となつてい
る。 In addition, when installing free access floorboards, air conditioning air is blown from under the floor, but since flat plates and equilateral angle steel are used, the resistance to airflow is large.

低いと言わざるを得なかつた。 Furthermore, in the case of floorboard construction, bolts 5a to 5
c. When assembling the nuts 6a to 6c and washers 7a to 7c at the construction site, the number of parts and the number of nuts to be tightened are very large, and the tightening direction is also horizontal, so the bolts 5b, which are close to the ground floor 8, 5
c, nuts 6b, 6c, and washers 7b, 7c are difficult to tighten because one side of the equilateral angle-shaped steel protrudes, and it is difficult to visually check from above to confirm that they are completely tightened. I have to say that the overall level of trust was low.

本考案は以上の欠点を解消した作業がやりやす
く、ケーブル等に傷付けない床板の耐震構造を提
供するものである。 The present invention eliminates the above-mentioned drawbacks and provides an earthquake-resistant structure for floorboards that is easy to work with and does not damage cables and the like.

もない。 Reference numeral 1 denotes support legs whose lower portions are fixed to the ground floor 8 at regular intervals with adhesive. The upper end of the support leg 1 has a first
There are screws as shown in the figure, and the adjustment table 12 and locking nut 13 are screwed into them. It is known that 11 is a free access floor plate placed on an adjustment table 12 to form a double floor. 16 is a pipe material, and has a straight pipe 16a that is fastened between the lower clasps adjacent to the support leg, and a curved pipe 16b that is fastened between the upper clasps. The curved pipe 16b has a straight center portion, both ends of the straight line extend obliquely toward the upper stopper of the support leg, and the tip thereof extends horizontally in the same manner as the straight pipe. This is an earthquake-resistant member in which the straight part of the curved pipe contacts the straight pipe, and the contact part is welded to form an integral structure. It is an earthquake-resistant member. The ends of the anti-seismic member 16 in both directions are processed so that they can be fastened, for example, crushed into a flat plate with holes so that a fastening member can be engaged therewith. The holes at the tips are engaged from above with bolts 18 embedded upward in 17a and 17b, and are tightened and fixed with washers 15 and nuts 14. Moreover, after the integrally structured anti-vibration member is engaged with the upward stopper, there is no need for fine adjustment, and the work is easy and the assembly time can be greatly shortened by simply tightening the nut. In this way, the seismic member 16 is tightened from four directions to one support leg 1, and the whole support leg 1 is connected, so that the strength of horizontal vibration against the floor plate can be expected. Furthermore, although bolts, nuts, etc. have been used as the tightening members, it goes without saying that the same effect as that of the present invention can be obtained if the tightening members are rivets, bosses, irregularities, hooks, or other materials that can be fixed with adhesives.
