To all wiz/omv it concern: Beit known that I, GEORGE LPEABODY, a

of -enns lvania, 'have invented certain new crete Constructions, of which the following is tothe accompan drawings, forming part,

of the specilica-tion, in which- 5 Figure 1 is' a vertical longitudinal sectional a Fig. .2 is a 1, indicated by the line Fig. 2 ig. 38L is a detail view of a portion of one 'of the main bars. Fig. 4 is a' angeingI the interlacing engagement o the terminals of the reinforcing elements. -Fi 6 is a vdetail view showing a' further mo cation. Fig. 7 is a detail view showing a modified construction of the tension member. Fig. 8 is a detail view showing 'a skeleton ers. Fig. 9- is a sectional detail view illustrating a modification.

Mylinvention refers toA improvements in recement, &o.,'and refers particularlyto the act the various strains in different directions to form a continuous anchoring construction. I employ a series of longitudinal wires or rods rigidly connected supplemental rods or bars a apted to engage a segregated body of the above the concrete or cement, preferabl y portion of posts or columns or in the bo tions of the concrete and. to equalize anddistribute the strain thereto from opposite directions inthe manner somewhat similar to cantaliver-bridge construction. I.

Reerrin to the drawines, 2 represents the posts or co umnsofa building'incoiporated 'f holdingterminals, as clearly shown.

lwith'the girders 3, beams 4, and floor-5, made of continuous concrete or cement.

6- represents main strengthening members, as bars, which are embedded longitudinali in the lower portions of the'beams and gir ers, with which are rigidly connected'in 'any `suitable mannerat 7- the upwardly-extendwiresl or rods 8. The l r's 6 are prefer- Sii provided with `series 'of notches a; at

eac side, adapted toreeeiye the wires or rods.

These wires or rods are setinto the notches and are referably made o'l" considerable len han'` are separated above the'rods 6,

crete sectionQ, ofwedge, key,'or other form, of the'beam or girder, the rods being extended horizontally, as showmthrough the floors 5 to the next beam or girder, where thesame construction is duplicated,l and so, on throughv out the bi'iilding. `An'especial advantage of this arrangementis that. the wei' ht o` .iloo'r is supported b the horizont rods actlingas' tension me'mi ers/@11d the strain con- .as own, and thencrossedinopposite direc- A `tion`s, so-as vto embrace between them a conthe 7 r;

stantly tends to tighten the englagement' of i the rods4 with r the concrete ra pull it apart. -As shown in Figs. 1,'2, and 3,

the rods constitute a continuous network throughout the 'length and breadth' ofthe licor, while the wedge or keystone sections 9 are embraced at intervals along the entire length of all of the -beams or girders. The u wardly-extending members 8 are prefer a ly arranged 'slanti'ngly'and dis osed in a manner best adapted to cross't elines of probablel fracture, (indicated at ar 05)' as is" -usualll'y practiced in this type of construction.v

In i

gs. -4 and 5 I have shown some of the reinforcin membersarranged in the manner just desoribed, other being connected to the main bar 6, extended upwardly through the beam .origirden preferably diverging, and

then extended in a horizontal direction. 'straight ahead through the door-body across the -next cross-beain,vgnirder,\or column and beyondto the other side. The reinforcing t er than to.

members offthe other side are similarly ex- :ce

tended over in a reverse direction and interlaced between the fiest-described terminals, as shownin Fig. 5, thus providin above the column or beam a closely-assemb ed series or' y this type of building construction.

Ey ieg In Fig. 6 I have shown a'lioor member 10 having su plemental upwardly extending' deflected olding-arms 11, the member bein secured toone end of one of the holding e ements just described, and it 1s obviousthat by this or any other suitable attachment individual floor-reinforcing. devices may be incorporated with the beam or girder"ties, which for such application may then be made in short sections.,` In Fig. 7- I have shown a further modification, wherein the triangular arrangement of the rods is -still maintained, the members.8"being deflected upwardly and diverged outwardly, then eirtended horizontally `in opposite directions, -but connected by bars or wires 12. By this construction is secured a practically continu-- ous tension element throughout the floor and irrily incorporating it 'With the beam or 1r er.

g vIn Fig. 8 is shown a skeleton connectingferrule 13, having ajlaring upper portion adapted to facilitate the continuous jo' of vertical column or post members, Whic thus abut one upon the other.

The essential feature of im rovement vof `my invention is that theghol ing elements -irmly engage and embrace triangular or other. sections of suitable form, around 3o -which they are looped or tied in. combination with the main anchoring-bar 3, the lateral `strains being transmitted thereto from the lighter floor construction, whereby the main elements Of-'the building are best utilized to .act as primary supports-fi. e., the columns,

beams, girders; &c., constitute the main supporting velements upon which -the entire ot' construction, and the character-of the binding elements which I vemploy is Well ada ted to their arrangement or application to tlhis construction, as well as that just described. The rods, bars, or wires are of a suitable strength according to the- Work in view. Their number and arrangement are within the judgment or discretion ofthe builder or designing architect, and it is obvious that various applications of the invention may be made to suit different requirements and conditions.

The reinforcing elements are laced in position during the progress of t e Work and previous to or durin the insertion of the concrete into the mo ding apparatus. The elements are sufficiently fiex'i le to be bent in the various directions'and when incorporated in the manner I have shown and described the system will be found to provide for all of the various'strains and'conditions arising andjincidental yto this type of construction. f
