'To all 'whomptt may concerm ing at 6l High street, Southampton, in the county bor-v ough of Southampton, England, have invented certain new and useful Improvements. in' Reiniorced'Concrete Beams or Columns, which is a divisional application of the original application filed January 19, 1906, Serial No. 296,842) of Which the 'following' is a specification. l

" My invention relates to armored or reinforced concrete construction, and comprises improvements in armored or reinforced concrete slabs, pieces, or blocks,v and means for joining such slabs or blocks together to form a monolithic whole in their combination to form permanent structures and casings for concrete construction toenable concrete construction or Work t'o be carried ont or erected under conditions in which it would be difli'clllt or impracticable to execute such work, either'as original, repair or supplementary work'. 'i

' The main object of lny invention is to provide rein` forced or armored concrete slabs or pieces of various convenient portable sizes, provision :being made so that wllen the slabs or pieces are assembled, they may be joined together to form a structure or casing which when lilled in withconcrete, or concrete and metal in any l'olm, will become a monolithic whole in which the armor is s'o placed that an evenly distributed strain is provided for throughout the lentirestructurc.

According to and in carrying out myinvention, I reinforce that is strengthen the concrete .sl-.lbs or pieces b y means of iron or steel bars of any approved section arranged to cross or recross the breadth, Iand also -if desired, the length of each `slab oi'- piece in a continuous diagonal alternating direction; the said bars Where they are bent over at the edges of the slabs or pieces forming a series of loops or eyes which project somewhat beyond the edges of the slabs or pieces so that when the slabs or pieces are brought together they may be connected by iron or steel rods. i

In the accompanying drawings which form apart of this specification, I have shown my improved construcytion of reinforced slabs, pieces, or blocks assembled together to form structures or casings for 1the construc-l tion, repair, or strengthening of concrete or other Workz Description of the drawings- Figure l. illustrates in isometrical perspective, the application of my invention toa floor construction. Fig. 2. illustrates in isometrical perspective, the application of myv invention to the repair or strengthening oi piles and other columns or pillars. Fig. 3. is a detail showing in isometrical perspective, the metal reinforcement and connection of the slabs used in the strengthening or-construction of columns. Fig. 4,v

shows in cross section, thevreinforced slab, and Fig. 5.

or steel bar or bars which I employ; these may be of any approved section, and according to my invention are, arranged to cross and recrossl the breadth, and if necessary or desiredfthebreadth and length of'each slab or piece in a continuousdagonal alternating direction without interrupting the\co ntinuity of the armor or reinforcing metal bar or rod, and so as to provide for an' evenly distributed strain throughout the entire ferro-concrete slab, piece, or structure. The said bars.. a where they are bent over, namely at the cdgesof the slabs 0r pieces, are so bent as to form a series of loops or eyes b which project somewhat beyond the edges o-the slabs or pieces. I

c denotes the concrete slab or block, and d denotes the rod by which adjacent slabs may be'joined as here after more fully described. The slabs c may have plain edges with'the metal loops or eyes b ofthe continuous bar a projectinglalternately on the edges of the slabs with the rod d passing through the eyes b and connect ing the slabs c; or the edges of the slabs c may be grooved to contain the e'yes b, or the eyes b may be embedded in the concrete formed as teeth along the edges of the slabs. n

The concrete slabs or' pieces c reinforced with the continuous bars a looped-at b, are mde in molds, the concrete being consolidated either by ramming in the usual way, or byV pressure in hand or mechanical presses. The slabs or pieces c .are'then'stacked to dry and mature; and when matured can be placed together so as to -ierrn the desired structure and immediately -take the, stress intended for them; ythus allowing the work of building the structure or casing `to proceed very rapidly, no waiting being necessary for the concrete in the structure ',tovmature before loading it or plastering, or otherwise finishing it.1

As previously stated, to join the slabs or pieces together to form the structure or casing, I employ iron or steel rods d whichy I insert or place` through the loops or eyes b of the reinforcing rods a o'n the meeting edges of the adjacent slabs' cj thus joining piece to piece and the whole together; the joints or meeting edges of the slabs thus formed being then grouted together with cement mortar or other suitable material or substance.

In constructing a column, pillar, or pile, I make the same of a number of the reinforced yslabs or pieces c connected together by the rods d so as to form a. hollow column ofnany desired form'br size, in Whichmayjbe arranged vertical iron or stee1 rodsjbars, er angles,

i Alowered until a suilicient number 'have been placed in.

provide against bending stresses; the remaining spaceso inclosed by theslabs, Vbeing filled in with concrete :rammed in the usual way; it -WilLbe seen that the coli ample of the carrying out ofmy invention, the column A is adapted to support aceiling or-loor composed of reinforced concrete slabs cconnected together'by the i rods d in the manner before described; a like construction can be-employed to form pillars. or piles of any requiredsize or section. The slabs c may be erected, and the column Acompletedlength by length until the required height is obtained.'

In the employment of the reinforced slabs c for the strengthening or` repair of columns, pillars, and piles, the example-shown 'isl that of a 'decayed timber pile. On reference it will be seen that in this case I build a Icasing composedof the reinforced slabs c (connected by bars d) length by length round the decayed-timber pile B, sch slabs being, when required, .placed and connected round the pile B above the water level and then lowered;l 'otherslabs c being then connectedand vertical series to rea-ch a firm bottom and extend up above thewater level; steel or iron rods,.bars, our-anglese may, if required, be placed vertically in thespace betiveen the slabs c forming the casing and the decayed pile. The casing formed bythe connected slabs c is `then filled in With concrete thus lcompleting the repair, strengthening, and protection of the pile B. lThe slabs c may be joined together and connected as shown, and

the casings may be of form to Vsuit any section of column,

loops .bandthe rods d before described; vadditional armor ye being introduced in the space inclosed .by the slabs'td tl'ce Ithe'bending stresses, the beam being made solid by concrete rammed i'n the usual way.

Itis obvious that slabs or pieces made. according to my invention being formed vin molds, may be ornamented in any 'manner possible by stamped or pressed methods as shown.

- My system ofconstruction can be applied to every description of reinforced or armored concreteA structures, butit is especially suitable for tidal Work, strengthening existing structures in erections where v great rapidity of erection is essential, temporarybuildings, and ornamental buildings. In the construction of a complete building or a Wall of any kind each and every piece c being provided with loops b andconnected byirodsl d to its adjoining piece or pieces,l all are connected together `thus forming a` 'complete monolithic Whole.

What I claim as my invention, and desire to secure by Letters Patent is:,-

1.-A column composed of a casing of slabs, each having a continuous strandA of Wire around which the slab is permanently molded, said wire bent upon itself to form diag- .onnlly disposed portions overlapping each other at their terminhlsto produce alining` eyes which project beyond opposite sidesof the slab, rods inserted in the eyes to unite the slabs, a piasticmaterialembedding 'the eyes and opposite sides of the slab, bonding rods engaging thc eyes f Vfor connecting the slabs together to form a -nnitary casing, a plastic material embedding'the eyes and the rods and al frame composed of longitudinal metal bars within thelatter and adapted to' rece'ive 'a concrete'core.

In testimony whereof I have hereunto set my hand in presence o two subscribing witnesses.

EDWARD COOPER POOLE.
