'- whose longitudinal cross section or profile has the appearance of cross bars placed at right angles to each other, so as to simulate ascending and descending steps, and adapted to be superposed or to overlap the adjacent structure of a like character so that the step-like gradations of one member fit into step-like gradations of another.

Another object of my invention is to provide such a structure with laterally extending ribs having flanges at the ends thereof to interlock with oppositely disposed flanges of an abutting structure of the same character.

Another object is to provide such a step like structure with an elevated ridge on one of the steps for guiding the movement of a superposed structure of the same character.

Still another object is to provide such a structure with a tongue-like perpendicularly disposed flange depending from one of the steps.

My invention, in its preferred embodiment, consists of an angle iron piling plate structure of ascending and descending rectangularly disposed gradations or steps, so that the step-like grade. tions of one member can be superposed above the members of the same character, the step-like gradations of one member fitting into the steplike gradations of the other member.

With the above and other objects and features in view, my invention will hereinafter be described and claimed.

Referring in detail to the drawing in which 1' have shown simple and practical embodiments of the invention, and in which similar reference characters designate corresponding parts throughout the several views,

Fig. 1 is a sectional view of the embodied structure showing gradations with inverted oppositely disposed interlocking extensions on each side of the structure,

Figures 2 and 3 are sectional views of the structure containing an increased number of gradations, and

Figure 4 is a plan or sectional view showing a plurality of step elements interlocked and superposed above one another so as to effect the appearance of a parquet flooring or a stencil.

In the specific embodiment of my invention, referring particularly to Figure 1, a web with a horizontal cross bar 1 has extensions 2 and 3 jutting from its ends at right angles thereto. To one side of and at right angles to extension 2 is a tongue flange 4 depending perpendicularly therefrom while the one side of step 3 has a flange or vertically disposed extension 5. Extending from vertical step 5 is an interlocking unit or arm connected at right angles to step 5 consisting of extensions 6, l and 8, all set at right angles to each other, to impart to the interlocking unit or arm the appearance of an L-shaped figure as shown in Figure 1, with its longer extension 6 horizontally connected to step 5.

Extending from the vertical extension 2 is an interlocking unit substantially L-shaped with its longer arm 9 at right angles to extension 2. The unit has the arm 10 at right angles to 9 and the smaller arm 11 substantially parallel to the arm 7 9 and bar 1. The smaller arm 11 is at right angles to arm 10. Depending from horizontal arm 9 is a tongue flange 4. Above the root of tongue flange 4 and on arm 9 is a slight projection or elevation 12 adapted to serve as a guide for properly positioning iron structures of the same type as shown in Figure 1 when interlocked and superposed above each other as shown in Figure 4.

As shown by Figure 1 of the drawing, it is to be noted that the web has inverted interlocking 30 units at opposite ends in which the respective component parts of one are parallel to the parts of the other although not set in the same planes.

In Figures 2 and 3 are shown multiple ribbed an le iron profiles or Webs with the interlocking units consisting of members 6, 7, 8 on one side and 9, 10 and 11 respectively on the other side, both units being oppositely disposed and having the horizontal members 8 and 11 in different planes.

The web structures shown in Figs. 2, 3 and 4 are joined together by horizontal bars 13 which are parallel to the bars 1. Such web structures accordingly may be of any desired length depending upon the width and/or length of the structure to be supported and finally concreted or cemented. In my preferred embodiments, each web structure whether multiple or single contains a tongue adjacent one of the interlocking members.

In accordance with the preferred embodiments of my invention, the web units with their respective members are brought into interlocking and superposed position. Referring to Figure 4 to illustrate the interlocking of the web structures, 10 the L-shaped interlocking unit of one structure consisting of angularly disposed extensions 6, '1 and 8 is in engagement with the interlocking unit consisting of arms 9, 10 and 11 of the adjacent web structure. In the superposition of one web 1 structure upon another, the horizontal extensions 2 and 3 of one structure rest on the horizontal bar 1 of the lower structure. The tongue flange 4 of the upper web and extension 6 of one of the interlocking units rest upon the horizontal extensions 2 and 3 respectively of the lower web.

The elevations or guides 12 on one of the arms of the interlocking unit allow for a certain clearance and tolerance between the superposed web structures.

The structure embodied in my invention is intended to be used especially for building floors, shafts and the like without requiring much rivet ing or welding as heretofore. Dimensions of the individual elements of the structure are such that whole sections can be superposed and interlocked as shown in Figure 4, in which the outer and inner steps are guided by the elevations or guide plates 12 to allow suificient clearance or space between each adjacently joined member, to be filled in with proper binding material so as to attain a unified structure in the form of a single plate. Plates joined in accordance with my invention are firmly interlocked and are adapted for use in telescopically boring the sub-surface and at the same time are of sufiicient strength to form a preliminary shell in the earth before setting up temporary and auxiliary framework within the shell for building up the wall structure within the tunneled portion of the shell. Furthermore, the plates, when joined and interlocked in accordance with my invention, can be used as units for ramming the same into the earth mass. The dimensions of the individual plate structures are so calculated that the outer and inner steps are adapted to be fitted within larger dimension steps with the allowance of some clearance between each step whereby only the elevations or guide plates support the superposed iron structure.

. larly disposed gradations.

Advantageous and better commercial co-operation is obtained by adding to the structure tongue shaped flanges depending from one of the horizontally disposed gradations and/or an elevation on one of the horizontal gradations for guiding the superpositioning of a structure of the same character, and in other forms, the L-shaped laterally extending member is added.

From the above description, taken in connection with the accompanying drawings, it is be-- lieved the form construction and several ad-- vantages of my invention will be clear. Further-- more, it is to be understood that the specific embodiments herein described may be changed without departing from the spirit and scope of my invention.
