R'BNIGRCED CONCRETE STRUCTURE.

Specification of ietters Patent. Pgttgd t?? jtl.

Application filed March 8, lOS. Serial No. 482,107'.

To all whom it may concern:

it lrnovvn that I, Mannion Dunas, a subject of the King of Belgium, residing at Ko. 112 line de liiederlterle, Brussels, in the Kingdom of Belgium, have invented certain new and useful improvements in Reinforced Concrete Structures, of which the following is a specification.

rhis invention has for its object improvements in reinforced concrete structures its principal object being to simplify considerably the ivorl of the builders by dispensing with the eofi'ering necessitated by the construction of monoliths of reinforced concrete by the methods heretofore adopted.

Another object of the invention is to permit of building, by means of elements of uniform dimensions, structures presenting a more or marked conicity.

These objects are obtained by utilizing, for structures of this kind7 separate elements of concrete manufactured and previously prepared in such a manner that the builders need do nothing -more than assemble them. These elements consist broadly speaking of blocks. slabs7 or keystones and connecting members or ribs7 of such forms that, When arranged in position to form a structure they constitute together at the joints recesses adapted for the reception of the reinforcing members that connect them one with the other and of the concrete in which these members are embedded. rl`he coffering is reduced to a single board per vertical joint between the ends of tivo adjacent blocks or keystones for closing the space which separates them on the side opposite to the connecting rib. The blocks and connecting ribs are adapted to serve for the construction of straight Walls as Well as for broken or circular Walls and tapering structures can be formed from them by reducing the interval betiveen the extremities of the blocks in each successive course.

Applications of the invention are illustra Aed by Way of example in the accompanying drawing, in Which:

Figure l represents in plan the arrangement of the various elements for the construction of a straightv Wall. Fig. 2 is a similar View of the arrangement of the elements for the construction of an angular or polygonal Wall. Fig. 3 is a similar vievv showing the same arrangement as Fig. 2 but With a smaller distance between the ends of the tivo adjacent blocks. Fig. al is a similar view showing the arrangement of the elements for the formation of an angle rib. Fig. 5 is a vertical section on the line AMA in Fig. l, shouting a number of superposed courses forming a ivall.

Referring to the drawings c', a are the blocks, slabs or keystones, L is the connecting rib, c is the board constituting the coffering, d. e are vertical rods of the framework or reinforcement of the structure, f is a inforcing rod which connects all the blocks of a` course horizontally one with the other. f/ is an iron hoop Which connects the tvvo vertical r ds (Z and e, /L is a band iron constituting the reinforcement of the connecting rib, b, and e' represents the concrete With which the spaces between the various elements are tilled after they have been ar` ranged in position.

Each of the blocus a is formed 'With a longitudinal groove j in its upper fr ce for receiving the reinforcing rod j and preferably vvith an angular reinforcement 7c at the end of its outer face and serving to fit into the rib .7).

Each of the connecting ribs 7) is formed of a block the rear face of which is recessed throughout its entire height in such a manner that it is Ll-shaped in horizontal section and that when several of these ribs are superposed their recesses together form a` continuous vertical groove.

lYhen the blocks ci are intended to form together a straight Wall, they are arranged With their grooves in line one With the other and in alinement with the vertical reinforcing rod d, which extends throughout the. height of the Wall to be constructed, as represented in F ig. l, and When they are to form an angle, they are arranged obliquely relatively to each other as shown in F 2 and 3. rEhen in front of the ends of their outer faces there is arranged a connecting rib 1When the blocks form an angle (Figs. 2 and 3) the edges Z of the rib which are adjacent to the outer faces of these blocks, preferably present an inclination corresponding to the sides of this angle. A. board c is then fixed against the extremities of the inner faces of the blocks; this board is fashioned in such a manner as to fit against these faces and the space com prised betiveen the inner faces of the sheath b and of the board e is hlled with concrete.

Vhen the concrete comes level with the channel in the blocks a, the horizontal reinforcing rod f is arranged in the channel and a horizontal reinforcing rod 7L is arranged in the cavity in the sheath I); these two rods arc arranged against the inner faces of the Vertical reinforcing rods (Z and e which are then connected one with the other by means of a binding of strong wire g. Finally the rods f and /t and the binding g are covered with concrete after which a fresh course is laid.

rlhe form of the blocks, of the ribs and of the reinforcing rods and their arrangement may be modified within Very wide limits without departing from the principle of the intention. Thus, for example, the end of a wall may be constituted as shown in F ig. e, in which the rib b surrounds all the faces of the end of the block a.

iii/That I claim and desire to secure by Letters atent of the United States is l. A structure of reinforced concrete consisting of blocks of concrete arranged end to end with a variable space between their adjacent ends, in combination with concrete connecting ribs the rear faces of which are recessed throughout their entire height, these ribs covering the outer faces of the' ends of each pair of blocks, horizontal reinforcing means connecting these blocks one with the other, Vertical reinforcing means located in the recesses of the ribs, means for connecting together the horizontal and Vertical reinforcing means and a concrete mortar filling entirely the spaces between the blocks and between the blocks and the ribs and embedding the reinforcing means.

2. A structure of reinforced concrete consisting of blocks of concrete arranged end to end along the two sides of an angle with a variable space between their adjacent ends, in combination with connecting ribs of concrete U-shaped in cross-section the ends of the lateral faces of the said ribs being applied to the outer faces of said blocks in iroximity to their adjacent ends, horizontal reinforcing means connecting the said blocks one with the other, vertical reinforcing means located in the recesses of the ribs, means for connecting together the horizontal and Vertical reinforcing means and a conn crete mortar filling entirely the spaces between the blocks and between the blocks and the ribs and embedding the reinforcing means.

3. A structure of reinforced concrete consisting of superposed courses each formed of concrete blocks arranged end to end along the two sides of an angle with a space between their adjaeent ends, this space being less in one course than in the preceding course, in combination with superposed concrete connecting ribs U-shaped in cross-section, the ends of the lateral faces of the said ribs being applied to the outer faces of the said blocks in proximity to their adjacent ends, horizontal reinforcing means connecting the said blocks one with the other, vertical reinforcing means located in the recesses of the ribs, means for connecting tcgether the horizontal and vertical reinforcing means and a. concrete mortar filling entirely the spaces between the blocks and between the blocks and theribs and embedding the reinforcing means.

In testimony whereof I affix my signature in presencel of two witnesses.
