Application filed April 14,

necessitating the employment of the mini-.. mum number of uprights at relatively long intervals, or where the character of the building is such as to make the use of comparatively long spans preferably as a means of avoiding the obstruction of the space in the room or area beneath the floor and ceiling structure, and in that connection to provide an arrangement of reinforcing means whereby sagging between the supports, due either to the weight of the structure or superimposed objects, is prevented while affording efficient means for applying and holding a plaster coating to form a finishing surface for the ceiling; and with this object in view the invention consists in a construction and combination of parts'of which a preferred embodiment is shown in them:- companying drawings, wherein Figure 1 is a plan view showing one complete span and adjacent portions of adjoining spans of a roofand ceiling construction embodying the invention.

Figure 2 is a sectional view taken on the plane indicated by the line 22 of Figure 1.

Figure 3 is a sectional view onan enlarged scale taken on the plane indicated by the line 3---3 of F igurcl.

Figure 4; is a detail view showing reiul'orcement for the lintels of o ienings suit" able for windows and doors.

Figure 5 is a vertical sectional view of window or door lintel.

Figure 6 is a vertical sectional view on the plane indicated by the line (5-48 of Figure l. to show the means whereby the extremities of the crossed tensile bars are anchored.

Figure 7 is a detail view of one of the anchoring plates.

Figure 8 is a view of one of the terra cotta blocks prior to the division thereof to form the plastering anchors.

Figure 9 is a plan view of a series of the 1921. Serial No. 461,300.

plastering anchors to show the preferred relative arrangement of the ribs thereof.

The structure embodies essentially the crossed or intersecting tensile rods 10 provided with turn buckles 11 or like means for varying the tension thereof and having their outer or remote extremities engaged with suitablehooks l2 on anchor plates 18 which are engaged with anchor pins 14 disposed verticallyin the walls shown at 15 or at the intersection of said walls and girders 16. or

at the intersection of two angular-1y extendingglrders'as "indicated at 1'2, said anchor pins being held in place by the anchor frames 18 embedded in said walls or girders.

The plaster anchoring elements 19 are formed as blocks indicated in detail in Figure 8 with exterior key grooves 20 and inwardly directed ribs 21 kerfed or weakened at 22 to facilitate separation or breakage preparatory to setting in the wall, and in positioning the same they are disposed upon a false frame or form (not shown) as in the ordinary practice with their flanges upwardly o1- inwardly'directed as indicated in Figures 2 and 3, beneath the plane of the tensile bars 10 and adapted to support a metallic reinforcing frame or netting 23 to receive the concrete or cement filler 24- in which, as in the ordinary practice, the battens 25 may be embedded for the attachment of the flooring boards 26.

Supplemental to the intersecting diagonally disposed tensilebars 10 are auxiliary tensile rods 27 engaged .at their outer ends to anchor rods 28 embedded inthe walls or girders and engaged atthe ir inner ends with bridge rods 29 supported by the tensile bars 10 and spanning the angles at the intersecting portions thereof. I

At the openings designed for windows and doors. and more especially those openings which are formed in the exterior walls are arranged the saddle teams 30 with which are connected reinforcing elements 81 engaging longitudinal reinforcing rods 32 embedded in the concrete filler tlfi lnfllC tlBlfl at 33 between the exterior facing masonry 34 of bricks or like material andv the inner layer of plaster anchoring elements it) cor-. responding with those employed in connec tion with the floor and ceiling structure.

The ribs of these plaster anchoring elements are preferably disposed in intersectmg relations as indicated in Figure 9 so as to form efiective keys by the concrete or eement which is employed as a filler and which occupies the spaces between said ribs.

The girder construction as indicated in Figure 3 includes the metallic bars 35 which may be of any approved construction embedded in the concrete filler 36 and covered exterior-1y by the plaster anchoring elements 19 oi. which those on the under side or the girder are disposed with their ribs in transverse relation thereto.

The invention having been described, what is claimed as new and useful is 1. A reenforced concrete span having intersecting diagonally disposed tensile bars terminally anchored in wall or girder structures and means for adjusting the tension of said bars, the anchoring means consistof vertical anchor pins and anchor plates engaged with said pins and provided with hooks for engagement by eyes at the extremities of said tensile bars.

2. A reenforced concrete span having intersecting diagonally disposed tensile bars terminally anchored in wall or girder structures and means for adjusting the tension of said bars, supplemented by auxiliary tensile rods radiating from the point of intersection of said tensile bars, connected at their outer ends to anchor bars in the wall and girder structures and engaged at their innor ends with bridge pieces spanning the angles between said tensile bars.

3. A reeniiorced concrete span having in tersecting diagonally disposed tensile bars terminally anchored in wall or concrete structures, auxiliary tensile rods disposed in bisecting relation with the angles formed by said intersecting diagonally disposed bars and connected at their outer ends to anchor bars in the wall and concrete structures and operatively connected at their inner ends with the diagonally disposed bars.

4. A reentorced concrete span having intersecting diagonally disposed tensile bars, said bars being longitudinally extensible and contractible anchor pins fitted in wall or girder structures and plates engaging with said pins and provided with hooks for engagement by eyes to the extremities ofsaid tensile bars.

In testimony whereof he ailixes his signature.
