reinforced concrete construction especially adapted for buildings, the object of the invention being to provide means for constructing a reinforced concrete building without the labor and expense 'in'volvediin erecting temporary frame-work and in tealeing down the same after the concrete-has set therein.

The invention consists in the novel construction and arrangement of parts all as will be fully described and more particularly pointed out in the appended claims.

The invention will be more readily understood by reference to the accompanying drawings forming a part of this specification, and in whic a Figure 1 is a top plan view of a column base, Fig. 2 is a side'elevation of said base, Fig. 3 is a detail side elevation showing a joint plate employed in the invention, Fig. 4 is a sectional elevation of a portion of a column base, Fig. 5 is a view of a post or column partly indicated by dotted lines and taken partly in section and partly in elevation, Fig. 6 is a transverse section taken on line ww of Fig. 5, Fig. 7 is a top plan view of the column shown 1n Fig. 5, Fig. 8 is a bottom plan view of said column, Figs. 9

- and 10 are respectively a side elevation and top plan view of the uppermost end of a metallic reinforcement of said column, Figs. 11 and 12 are respectfully a side elevation and top plan view of a metallic girder reinforcement, Figs. 13 and 14 are respectively a side elevation. and end elevation of a girder, Fig. 15 a perspective view \of the angle iron employed in theconstruction.

The preferred form of construction of my invention as illustrated in the accompanying drawings comprises primarily a column base 1 which may rest upon any suitable foundation, not shown, a column'2 sup ported by said column base, a girder 3 supported by said column, a floor joist 4, and floor slabs 5 supported-by said girder, there being the usual number of these parts all of which are formed of reinforced concrete forced concrete.

columns 2 may be modified from the con-' prior to erection.. Thus the parts of a concrete building are manufactured in shops or other suitable places and fitted and: numbered preparatory to erection on the site of the building in a manner similar to the production of structural steel work. Provisions are made aswill' be described. here .inafter, for rigidly securing and cementing the concrete parts together-when assembled, so that the building when finished will be substantially a one-piece structure of rein:- It is understood that the struction shown to render the same suitable for all parts of a building,'the column shown being an interior column and provided with means for the reception of girders 3 oneach side thereof. It is obvious that corner posts or columns connectwith girders at only two sides thereof, and that side columns connect with girders at three sides.

After the parts of the structure are assembled, a floor finish of concrete of a suitable consistency may be applied to floor slabs, as shown, or a tile floor embedded in concrete may be used. A wood floor'may be laid if desired, after securing wood floor strips in theooncrete' in a manner as will be readily understood by those skilled in the art. i

Each column base 1 comprises a metallic angle-iron frame reinforcement having four vertical members 6 and radiating horizontal members 7, the latter members forming an efficient brace for the columns 2 to be. erected on said base 1. Each of the members 7 is formed integrally with the corresponding member 6, one leg of the angle-iron being split on a horizontal line from the edge to the vertex line thereof and the other leg bent at a right angle at thes lit as shown in Fig. 15. Each column 2 is o a lengthcorre tially triangular stiffening plates 8- and which facilitate a rigid connection between the vertical members 6 and the horizontal members 7, there being tie-plates 9 which are arranged as shown and riveted to the rigidly together.

perforations 11 13 of the columns2 are provided with perforations 12 adapted to register with the the members 6, there being elongated perforations 15 molded in the concrete of the columns 2 which. formextensions of the perforations 14.

In order to erect a column 2 a layer of soft concrete or grout 15 is first applied to the top of the column base 1, 'or a preceding column, and the column placed in position. Temporary pins, not shown, are passed through the

perforations

11 and 14 to hold the column in position until the grout 15' has set. Joint-plates 10 are secured to the top of each column, as illus trated in the several figures, ready to receive the succeeding column.

The reinforcing frame 13 of each column 2 is provided with tie-plates 16 the uppermost thereof being formed integral with bracket like reinforcing members 17 which are provided in the brackets 18 as clearly illustrated in Fi s. 9 and 10. Each bracket reinforcing mem er 17 is provided with a central bracket member 17 riveted thereto and havin a plurality of concrete retaining teeth 19, t ese teeth serving as an eflicient binder for the concrete as will be readily understood. The top of each column 2 is rovided with a series of recesses 20, the

ottom surfaces of which are arranged on the same level as the brackets 18 and there being small recesses 21 formed 1n the botsmall hook 25 at the extremity thereof, as

shown in Fig. 11, said hook serving to render-the connection of the girder 20 with the column 2 doubly secure, it bein understood that grout 15. when applie to the topof the column will securely hold the rods 23 in position. Each girder 3 is provided with a reinforcing frame-work 26 the rods of which are secured together by means of tie-wires 27, a part of the rods of the frame work terminating in the rods 23 as clearly shown in Figs. 11 and 12. A part I of the rods of the frame-work 26 terminate in downward projections 28 which are adapted to register with and seat in the small perforations 21 as shown in Fig. 7.

The upper surface of each girder 3 is provided with a series of vertically disposed pins 29, which are adapted to facilitate the positioning of floor slabs as will be seen later in the description. j

A concrete structure as set forth is e00 nomical to produce in that the parts thereof are made in shops especially equipped for their manufacture. Moreover, a concrete building of this order may be erected at any time of the year regardless of weather conditions, extreme cold not affecting the erection of a building constructed in the manner described so much as when concrete is poured into molds on the site of the building.

While I have illustrated and described the preferred construction for carrying my invention into effect this is capable of variation and modification Without departing from the spirit of the invention. I, therefore, do not wish to be limited to-the exact details of construction as set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention What I claim as new and desire to secure by Letters Patent is:
