FILE AND PANEL SYSTEM FOR GDNGBETE CONSTRUCTION.

Specification of Letters Patent. Patented Dec, 21, 192() Application filed September 2, 1919. Serial No. 321,118.

To all whom "it may concern:

Be it known that I, CARL GEORGE Dams, a citizen of Transvaal, South Africa, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Pile and Panel Systems for Concrete Construction, of which the following is a full, clear, and exact description.

My invention relates to improvements in concrete constructions preferably for use under water, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide a device which may take the place of caissons or coffer dams.

A further object of my invention is to provide a sub-aqueous concrete construction which may be readily installed, and which when installed partakes of the nature of a monolithic structure.

A further object of my invention is to provide a sub-aqueous construction which may be installed at relatively low cost.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which- Figure 1 is a section through a portion of the construction,

Fig. 2 is a sectional view of a portion of a modified form,

Fig. 3 is a side view of one of the piles,

Fig. 4 is a section along the line 44 of Fig. 8,

Fig. 5 is a section along the line 5 -5 of Fig. 3, and

Fig. 6 is a sectional View showing another modified form.

Fig. 7 is a sectional view through the double panel wall with a single row of piles.

Referring now particularly to Figs. 1, 3, and 1, I have shown therein a pile or post having a body portion 1. in the shape of a cross. Each of the arms of the cross is provided with a shoulder 2. These shoulders form extensions of the cross, and the pile tapers downwardly from the shoulders to the bottom, the bottom of the pile being square, as shown in Fig. 5. The pile is provided with a metal pile shoe 3 to facilitate the driving of the pile. At various intervals dowel pins 4: are provided, these pins extending into the spaces between the adjacent arms of the cross. If desired, reinforcing material, such as rods or bars (not shown), may be used in strengthening the pile. In each arm of the cross is a vertically disposed guide groove 5 extending to one of the outer faces of the arm. In the drawings, it will be seen that the grooves are so located that there is always one groove for each side or face of the pile. The grooves are enlarged at their interior ends.

Arranged to cooperate with the piles are panels or slabs 6 which are made of concrete, preferably reinforced. Each of these panels is provided with a recess 7 on its outer face at each end of the panel. are designed to rest on the shoulders 2 in the manner shown in the drawings, with their ends spaced apart. The panels are lowered into position after the piles are set, guide piles 8 being provided for facilitatingrthe guiding of the slabs into their proper position. Each slab is provided with a guide bolt or pin 9 which is carried in a threaded socket 10, embedded in the inner face of the slab. The heads of the guide bolts pass within the vertical grooves 5, so that the ends of the panels are spaced apart at the proper distance. Each panel is provided with a groove 11 arranged to receive the ends of a metal retaining member 12. The latter is preferably in the form of a corrugated sheet metal strip whose ends are fastened to cylindrical rods or wires which may he slipped downwardly in the grooves 11 so as to retain the member 12 in position. When the panels are in position, the space between the ends of the panels is filled with grout 13 by means of a tube. When this hardens, it binds the ends of the panels together, and also binds them to the piles, thus making a monolithic structure.

In Fig. 1, I have shown the panels as attached only on one side of the pile. This is useful for light wharves without heavy trailic, as, for instance, in passenger landings, also for waterways with little or no current, to protect the bank against erosion caused by the wash of passing vessels. In such cases, the panels may be placed on the inside of the piles, jetted in place, and are kept there by the pressure of the back fill when the piles are not endangered from damage through drifting logs, etc.

In Fig. 2, I have shown a double wall con- The panels struction. In this figure also, the piles are turned 45 from the position shown in Fig. 1. In Fig. 2 the panels 6 are secured at their ends to a pile which has its guide grooves 5 in the ends of the arms. In this form of construction, two piles are placed near each other to support the opposed ends of the section, but are spaced apart, so that the grout is placed in the space between the ends, to form what I might term a twopile joint as distinguished from the single pile joint on one side only of the pile of the con- .struction shown in Fig. 1 In the construction shown in Fig. 2 the space between the slabs or panels is filled with concrete by means of a tube under water, being held by reinforcing hooks or stays 19.

In Fig. 6, I have shown a modified form of the device; In this figure a pile 21 has a vertical face onone side thereof to receive a panel 22 which rests on a shoulder 23. The opposite side of the pile is provided with an inclined extension 24 which terminates at its bottom in an integral prolongation 25' of the pile, a bracing member 26 being provided, as shown. In this form of the construction, the pile is driven in place and a panel 27 is laid with its face against the inclined extension 24. The bottom of the panel is provided with an outwardly extending integral flange or foot 28. It will be understood that the panels are groute-il together in this form of construction pre cisely as in the other forms. The space between the opposed panels 22 and 24: is filled with concrete 29 in the manner described, thus making a very solid structure.

A numberof different advantages arise from the use of my improved concrete construction. In the first place, the peculiar cross shape gives the pile a greater stifiness and vfriction load capacity than anyvother shape. The use of the pile and panel system saves the building of a separate cofferdam and the work of removing the same. It saves also thebuilding of separate form walls and their removal and consequently it is the means of saving considerable material, labor, and time. 7

V In the use of my improved construction for cofl'er-dams, there is another advantage. In the ordinary coffer-dam the leakage necessitates continual pumping out. In the mono lithic structure described herein, afterzthe water has been once pumped out, there is no necessity of further pumping, because there is no leakage through the solid concrete wall. V

V For extra deep water work, the double panel style, shown in Fig. 7 is used as a cofler-dam and outer-shell in the same manner as the single style, in lighter constructions. j V 7 Obviously, other uses than those described mightbe made of my improved sub-aqueous portion and having shoulders at the top of the tapered portion and a series of concrete panels or slabs arranged to rest on the shoulders of thepiles to form awall.

2. A concrete construction comprising a series of piles spaced apart, each of said piles having a shoulder and a series of concrete panels or slabs adapted to rest on the shoulders of the piles, and means for joining the ends of the panels together to form a monolithic structure. i

3. A concrete construction comprising a plurality of concrete piles having shoulders, a plurality of concrete panels arranged to rest on the shoulders, each of said panels having a recess at its ends, and a concrete binding material disposed inthe registering recesses of the ends of the adjacent panels.

4. In a concrete construction, a concrete pile having 'a straight body portion and a tapered portion integral with said body portion and having shoulders at the top of the tapered portion, said straight body portion and said tapered portion having a cross section the shape of a cross.

5. In a concrete construction, a concrete pile having a cross section the shape of a cross, and being provided with shoulders and dowel pins arranged to project into the spaces between the arms of the cross.

6. Ina concrete construction, a concrete pile having a cross section the shape of a cross, and being provided with shoulders and dowel pins arranged to project into the spaces between the arms of the "cross, said piles having longitudinally extending guide grooves projecting from the faces thereof.
