1 The invention described herein may be manufactured. andv used by or for the. Government for governmental purposes, without payment to me of any royalty thereon.
This invention relates to a knockdown construction which may be used for many different structural applications, including roadways,-
Walls, box pillars, coffer-dams and the like, more particularly, it, is directed to a portable roadway or runway or airplane landing mat construction.
One of the objects of the invention is to. provide a structural unit substantially in the form of an I-beam, the cross-bars. of which form recesses-on opposite sides of the web of the I-beam, with the recesses being of such a shape as to be. interchangeable with other similar units by re.- ceiving in such recesses either end of similar structural units.
Another object of the invention is to provide an improved portable roadway construction including a multiplicity of interchangeable andihterlocking units which may be joined together readily without the necessity of employing bolts, rivets or any other extraneous fastening means.
Another object of the invention is to provide a roadway construction made up of. independent duplicate units which are capable of interlocking with each other and which, when so interlocked, are also capable of withstanding any strain put upon them.
Another object of the invention is to provide a construction made up of a plurality of separate interlocking units which may be employed not only'to provide a surface but also may beinterlocked into a four-sided structure to form box beams, pillars, cofier-dams and ;.-the like.
Another object of the invention is to provide a portable knockdown construction in which a.plu-
rality of interchangeable and interlocking units are employed, possessing maximum strength when in position, and yet being capable of separation after use without. distortion or modification, and reassembled for. use in another location, withthe original strength and the general usefulness of the individual units being unimpaired and capable of reassembly.
With the above and other objects and advantages in view, the invention consists of certain features of construction and operation of parts, which will hereinafter be described and shown in the accompanying drawings, in which:
Fig. 1 is a fragmentary top plan view of a plurality of interlocking, independent units joinedtogether for forming a roadway or landing. mat construction;

Fig. 3 is a cross-sectional view thereof taken on line 3-3 of Fig. 2;

of a single layer of the-interlocking units;

Fig, 7 is a fragmentary perspective. end; view illustrating the manner. in which the. units may be interlocked into afour-sid'ed structurev to. form box beams, pillars, coffer-dams or the like..
In general, the improved structural units. of the present. invention consist of" a'pluralit'y o1" interlocking units substantially in the formof I-beams including webs having transverse flanges on the opposite longitudinal edges thereof. The transverse flanges extend at right.
angles to, and equal. distances from, opposite sides of the webs and are provided with curved lateral hookflanges which depend inwardly'relative to the web from theouter' extremities" of the flanges substantially at right angles to, the:
flanges and parallel to the. webs, whereby recesses are formed on the sections adjacent to opposite sides of and along thelongitudinal edges of the webs. By providing the recesses on the units; the
hook flanges on the transversebase flanges of similar sections may engage in the recesses of the other adjacent sections, wherebyaseries of the I-beam units may be detachably connectedin interlocking relation to form a single layer roadway surface or mat, as illustrated-in Fig. 4-
of the drawings.
If the area over which the roadway extends requires greater strength, additional layers of interlocked relation by means of a series: of. The units I, one of which is similar units I. shown in detail in Figs. 2 and 3, includeaweb portion 2 having transverse flanges 3 and 3' pro.-
vided on opposite, longitudinal edges thereof; which flanges 3 and 3 extendat right. anglesto.
the web 2 an equal distance from its opposite sides 4 and 4. The transverse flanges 3 and 3' are formed adjacent to their longitudinal edges with curved lateral hook flanges 5 and 5, respectively, which depend inwardly from the outer extremities or edges thereof substantially at right angles to the transverse flanges 3 and 3 and parallel with the web 2, whereby recesses 6 and 6' are formed on the vertical units l adjacent to the opposite sides 4 and 4' of the web 2 and along the longitudinal edges thereof.
Each of the horizontally extending units l, which units are duplicates of the vertically extending units Leonsists of a web 2 having transverse flanges 1 and 1 provided on opposite longitudinal edges of the web and extending at right angles to the web an equal distance from its opposite sides 8 and 8. The transverse flanges I and I are provided with curved lateral hook flanges 9 and 9, respectively, which depend inwardly from the outer extremities or edges of the transverse flanges 1 and T substantially at right angles thereto and parallel with the web 2, whereby recesses l and ID are formed on the horizontally extending sections I adjacent to the opposite sides 8 and 8' of the web 2 and along the longitudinal edges thereof.
In forming the portable roadway or mat construction using a single layer of the interchangeable interlocking units l and I, respectively, as illustrated in Fig. 4, a plurality of the units 1 are arranged and held in suitably spaced interlocked relation by means of a series of the similar units I having the transverse flanges I and l of the units abutting against the sides 4 and 4', respectively, of the webs 2 of the vertically extending units, with the lateral hook flanges 9 and9 on the flanges I and 1 of the units l engaging in the recesses 6 and 6 of adjacent units l and abutting against the hook flanges and 5 of the units.
Should it be required to have a roadway, landing mat or bridge flooring construction with a greater strength than provided by a single layer of the interlocking units as illustrated in Fig. 4, additional layers of the units may be interlocked with'each other as shown in Figs. 5 and 6. In Fig. 5, a, plurality of interchangeable units are interlocked with each other to provide a one and one-half or two layer construction in which additional vertically and horizontally extending units 1 and l, respectively, are provided, with the transverse flanges 3' of the additional units l abutting against the upper sides 8' of the webs 2 on the first layer of units l and the hook flanges 5 of the additional units engaging in a recess and a recess l0 adjacent to the sides 8 of the Webs 2' on the units I of the first layer of units. The Webs 2' of the units I, employed in forming the second layer of the roadway construction, abut against the upper transverse flanges 3 of the vertically extending units I used in providing the first layer of the roadway construction and the hook flanges 9 and 9' provided on the transverse flanges "l and 1', respectively, of the last-mentioned units l engage in the recesses 6 and 6 of the units l.
Having thus described my invention, what I claim as new and wish to secure by Letters Patent 1.
