DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] Please refer to FIGS. 1 and 2. The metallic elevated floorboard structure of the present invention is composed of an elevated floorboard 1, leg members 2, base seats 3, wire channels 4, central cover boards 5 and side cover boards 6. The elevated floorboard 1 is formed of a square plane iron panel 11 having punch holes 12 at equal intervals. Each punch hole 12 has downward extending hole wall 121. A concave iron board 16 having multiple concaves is fitted with the hole wall 121. Then the hole wall 121 is punched to firmly rivet the concave iron board 16 with the iron panel 11. The periphery of the elevated floorboard 1 is stepped to form a flange 13 having notches 14 at intervals. In addition, the four corners of the elevated floorboard 1 are formed with hexagonal bores 15. The leg member 2 includes a plastic collar 21 corresponding to the hexagonal bore 15 and fitted therein. The bot tom of the plastic collar 21 is formed with a flange 22. A metal nut 23 having inner thread 26 is further fitted into the plastic collar 21. The outer circumference of the met al nut 23 is formed with a flange 25 and longitudinal sculptured stripes 24 for enhancing the tightness of fitting with the plastic collar 21 and avoiding rotation. The metal nut 23 is screwed with a thread rod 27 provided with a fastening nut 28 and a C-shaped washer 281. The upper end of the thread rod 27 is cut with a split 29 for a blade screwdriver from upper end to adjust the height of the thread rod 27. The leg member 2 is directly assembled after the elevated floorboard 1 is manufactured in the factory. Therefore, it is unnecessary to mount the leg member in working site.

[0019] The base seat 3 is a square body. Each of four side thereof is formed with a notch 31. Each of four corners is provided with an upward projecting hollow cylindrical boss 32 for fitting with the thread rod 27 of the leg member 2.

[0020] The wire channel 4 is a U-shaped frame body. Front and rear ends thereof are respectively formed with two tenons 41 corresponding to the notches 31 of the base seat.

[0021] The central cover board 5 is also a square plate body. Each of four corners thereof is formed with a thread hole 51. Two sides of each thread hole 51 are formed with assistant locating plates 52.

[0022] The side cover board 6 is a rectangular plate body. Two lateral sides thereof are formed with downward bent arch locating plates 61 and downward projecting assistant locating plates 62.

[0023] Referring to FIG. 3, after the elevated floorboard 1 is manufactured at the factory, the elevated floorboard 1 is reversed with the hexagonal bore 15 fitted on a projecting post 91 of each corner of a tool 9. The plastic collar 21 of the leg member 2 is inserted into and firmly located in the hexagonal bore 15. Then the end with the sculptured stripes 24 of the metal nut 23 is inserted into the plastic collar 21 to tightly fit with the plastic collar 21. Furthermore, the thread rod 27 screwed with the fastening nut 28 is passed through the C-shaped washer 281 and then screwed into the metal nut 23 until the thread rod 27 abuts against the top of the projecting post 91 of the tool 9. Accordingly, the leg members 2 of the elevated floorboards 1 released from the factory will have unified height X without difference. Such elevated floorboard 1 is specifically designed for offices so that it has a certain height X. In working site, it is unnecessary to assemble the leg members so that the working efficiency can be promoted. Moreover, referring to FIG. 3A, the iron material is relatively heavy. However, two elevated floorboards 1 can overlap each other to form a hollow configuration. This reduces volume and weight of the elevated floorboards 1 so that the elevated floorboards 1 can be easily packed and transferred without increasing shipping cost.

[0024] Please refer to FIGS. 4 to 6. The tenons 41 of four wire channels 4 are inlaid into the notches 31 of four sides of the base seat 3. Then, the thread rod 27 of the leg member 2 connected to each corner of four elevated floorboards 1 is inserted into the hollow cylindrical boss 32 of the base seat 3. Wires 8 are freely laid through the wire channels 4. Then, a central cover board 5 is placed between four elevated floorboards 1. The assistant locating plates 52 beside the thread holes 51 of the central cover board 5 are slightly recessed so that the four thread holes 51 can be easily aimed at the hexagonal bores of the four elevated floorboards 1. At this time, four screws are used to lock the central cover board 5 on the four elevated floorboards 1. In addition, the arch locating plate 61 on one side of each of several side cover boards 6 (or wire outlet seats 7 ) is engaged in the notch 14 of the flange 13 of the elevated floorboard 1. (The sharp edge of the locating plate is hidden to avoid scrape of the wires as shown in FIG. 4. ) The assistant locating plate 62 on the other side also can be easily engaged with the end section of the flange 13 to complete the assembly of the elevated floorboard structure.

[0025] In case of irregular ground face, as shown in FIGS. 2 and 3, the screws of the central cover board 5 are unscrewed. The plastic collar 21 is tightly fitted in the hexagonal bore 15 and the metal nut 23 is meshed with the plastic collar 21 by means of the sculptured stripes 24 so that the elevated floorboard 1, plastic collar 21 and the metal nut 23 are integrally bound with each other. A blade screwdriver is extended into the split 29 of the thread rod 27 to clockwise or counterclockwise rotate the thread rod 27 for adjusting the height thereof. In the case that it is necessary to adjust the thread rod 27 to a higher position, after adjusted, the side cover board 6 is lifted for further tightening the fastening nut 28. In the case that the thread rod 27 is to be adjusted to a lower position, it is necessary to first lift the side cover board 6 to untighten the fastening nut 28. After the adjustment is completed, the fastening nut 28 is again tightened.

[0026] The metallic network elevated floorboard structure of the present invention has the following advantages:

[0027] 1. The plane iron panel and the concave iron board are directly riveted by means of the punch holes without using any cement. Therefore, the metallic elevated floorboard has light weight and also has enhanced ability to bear load.

[0028] 2. The metallic elevated floorboard is made by direct riveting so that after assembled, the metallic elevated floorboard can be immediately used. In contrast to the present invention, it takes three weeks prior to use of the conventional cement elevated floorboard. Therefore, the production can be speeded and the cost is lowered.

[0029] 3. The metallic elevated floorboard has light weight so that a building is free from excessive load and the safety can be ensured.

[0030] 4. The metallic elevated floorboard has light weight so that it is easy and time-saving to transfer or work on the metallic elevated floorboard.

[0031] The above embodiment is only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiment can be made without departing from the spirit of the present invention.
