l0 Claims.

This invention relates to improvements in flooring and method of assembly and forming of` parts thereof, said parts may be made of any material or materials suitable for forming plates or tiles and associated elements entering into the floor- More specifically the invention relates to metallic flooring structures preferably embodying Fig. l is a plan view showing apart of a flooring embodying my invention;

Fig. 2, a perspective view of the portion of flooring shown in Fig. 1, in spaced apart relationship;

Fig. 3, a cross sectional View on the line III-III of Fig. l;

Fig. 4, a transverse sectional view on the line IV--IV of Fig. l;

Fig. 5, a perspective `view of a channel member in inverted position;

Fig. 6, a perspective View showing the manner in which the material may be rolled and punched;

Fig. 7, a perspective view showing a modifiedk channel element; and

Fig. 8,v a perspective view showing a Z-clip and strip.

Referring to the drawings, the floor structure as illustrated and as preferred includes any delsired number of units, tiles or plates 5, preferably formedl of rolled steel channel members Vcut to the desired size, said tiles or plates have flanges 6 and web portions 1, the latter being designed to be positioned in a horizontal plane so as to form a flat even surface, constituting, if desired, a wear surface of the flooring.

As shown, each flange is formed with one or more series of openings or slots 8 arranged in different elevations inthe flanges and designed to receive locking and supporting elements of any preferred and suitable form. The said locking and supporting elements as shown in one embodiment of the floor structure consist of Z-clips or cleats designated generally 9 and including a horizontal portion I0 adapted to be insertedv into an opening or slot 8, a vertically extending portion Il, and a horizontal apertured portion l2. The aperture I3 of portion I2 is designed to receive an anchoring screw or other anchoring de vice I4. If preferred the Z-clips may be xedly or adjustably mounted on a relatively thin lmetal strip 9a having, if desired, predetermined spaced apart apertures 13a that register with the apertures of the Z-clips 9 when the latter are applied to the strip, see Figure 8.

It will be noted that after inserting the horizontal portion I of the element 9 into a slot or opening in a flange of the plate a part of the vertical portion Il extends outwardhr from the flange to provide a shoulder. This part or shoulf der is designed when an adjacent unit or member 5 is positioned relative to the rst unit in the act of assembling the members, to co-me into contact with the under surface of the web of the said unit to support an edge thereof. It will thus be noted that the combination of elements arranged as described will coact to function as an anchoring and supporting means for adjoining members 5.

Fig. 2 shows members 5 and the cleats or clips 9,

which are to' constitute adjoining members of the flooring, spaced apart. A reference'to this figure will show that a member 5, here designated a, has its flanges 6 extending in one direction and that the other members, here designated b, c, d andr e, all have"their flanges extending inthe same direction and at right angles to the flanges of the member a.

Various methods of assembling the plates or r tiles together with the clips or cleats on the supporting structure may be followed. As a method of assembling, and referring to Fig. 2, it will be seen that when the said members are brought together or assembled the clips 9 or portions thereof associated with one flange oi member a will cooperate with the unflanged edge of a memv ber d to support an edge of the web portion l of said member d, while said clips being secured to a supporting structure will hold down the member a; and the clips, not shown, on the opposite end of membera Will function in a similar manner for supporting the unll-anged web portion of member b. The clips that are entered in the slots of the flange of member e are designed to fasten said member to the supporting structure and to cooperate with the unanged portion of member a for supporting an edge of the web .nate parts oi a wood sub-floor.

to members a and e, that is to say to hold down member c and support the other unflanged portion of member a. The assembled nooring thus includes, interlocking or integrating reciprocal floor plates or tiles.

The members are of such construction that they may be readily fabricated, transported and disposed in position upon any suitable supporting structure, as for example, in the manner shown by Figs. 3 and 4, in which l5 and i6 desig- It is evident, in some instances the members 5 may be reinforced by a reinforcing element as il, see Fig. 6, and

may have its flanges slotted as at 8 and one of the flanges formed with integral projections IS, while its other iiange is provided` with slots ES, see Fig. '7 v It is contemplated that the web portions of the channel members may be utilized as the tread or wearing surfaces of the flooring, and further, that the interlocking or integrating reciprocal door plates may be preformed and stocked in several grades. Such as, one grade for floors for warehouses, sidewalks, and other constructions in which hard usage is contemplated; a grade for monumental or public buildings having perhaps an inlaid or special surface or appearance; and a grade particularly adapted for domestic use.

t will be understood that the floor units, owing to the configuration of the said units and the manner of assembly permits them to be installed as an integral part of a cement, mastic or plastic support, or they may be disposed -on the top of old existing metal or wood oors 0r other supporting structures. It will be further noted that the combination of the said units and the arrangement thereof, together with the interlocking and supporting elements is of such character, that in the event the floor is to be repaired, any one or more plates may be removed and new plates installed in the place of the said removed units. Attention is called to the further fact that the flanges of the channel units are provided with staggered openings whereby the interlocking and supporting elements or clips may be entered therein in order to bring the wearing surfaces of the said channel units into a horizontal plane. This construction permits of flexibility, expansion and contraction and a construction that would prevent buckling of the floor.

As illustrated it will be seen that the adjoining plates are positioned in abutting relationship and that the clips, cleats or other fastening means employed are concealed from view as all portions thereof are below the upper surfaces of the assembled plates.
