4To all :whom it 1mi/ concern.'
Be it known t at I, EDGAR J. DBAYER,
citizen of the United States, residing at Dayton in the county of Montgomeryand State of hio, have invented certain new and useful Improvements in Molds for Concrete Building Construction; and I do declare the following to be a JfullI clear, and exact dencription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon which form a part of this specification.
This invention comprises a universal metal concrete form for reinforced concrete work. The object of the invention is to provide a metal form in which the entire concrete v structure of each ioor, to-wit-'the columns,
girders, beams and floor may be laid, and a A ein le set of forms used.
beam molds on the line a a of Fig. 2.
BIS
he arts of the form may be put up or assemb ed in a comparatively short time, and taken apart in an equally short space of time for each succeeding operation until the entire floor structure of a building is completed.
Precedin a detail description of the in-L vention, re erence is made to the accompanying drawings, of which-'- y Figure 1, is a erspective view of my irnproved universa metal concrete form by means of which the concrete gi ers, beams and corner posts or column!) together with the concrete ooring are olihstructed. Fig. 2,. is a sectional elevation oii the line y-fy of Fig. 1. Fig. 3, is a sectional elevation on the line :c a: of big. l. Fig. 4, is a detail view of the support or the bottom of the girder or Fi 5 is a detail sectional view showing the magnet,1 of unitin the sections of the molds on the line 'v o 'o Fi 3. Fig. 5 is a sectional view on the line b of Fig. 2.
In a detail description .of the invention, similar reference characters indicate correspending parts. i
The forms or molds by means of which the corner columns, the girders extending between the corner columns, the beams extending between the girdere and the Boor, vare formed from concrete are illustrated more full in the assembled view Fig. 1. The 'i' et molds or forms and the beam molds or oims extend at right angles and intersect each other, and the upxrig t post or column forms or molds join t ends of the gil-der :formsl or molds.
and beam forms or molds, said sections being joined by double angle irons B which lie vertically on the outer sides of said sections and overlap the abutting edges` of said sections; the angle irons B are joined by bolts c to unite said sections. At the points whore the irder forms or molds intersect the beani orms or molds, they are united by angle irons B which are likewise united by bolts c to the abutting sections.
C designates angle beads fastened to the mold bottoms D to provide chamfeis on the lower longitudinal edges of the concrete girders or beams when finished. The bot toms D are adjustable with their supports to obtain the desired depth of beam or giider when the molds are assembled as iii big. 1. The said bottoms are supported on adjustable brackets E secured to double .angle irons or bars F by means of bolts G which are insertible in the desired openings c. The double angle irons or bars 11 are secured to the angle irons B B which unite the mold sections A A by bolts G' which enter openings F in the horizontal angle irons F. There is one of the double angle irons F placed at each joint between the mold sec tions A A. Different horizontal widths ci? the beams aiid,?girdeis may be obtained by increasing theifiyidtli of the molds, which is done by motfi'n outwardly the angle irons B B and securing them to the angle irons F by the bolts G. It will be observed that the an le irons F are provided with a series of bo t orifices F into which the bolts G may ass in thus moving outwardly the angle irons B. The molds for forming the concrete girders are of greater depth than the molds for forming the concrete beams owing to the girders having to sustain a greater Weight. The sections A A re braced by tie rods H which connect with the angle irons B B' and the angle irons or bars F, and have turn-buckles I for tightening them.
J designates a shoring or support ofwhich there is one at every other section of the molds to take the entire weight of the girders, beams and flooring; they are adjusted to raise or lower the molds or forms by meann of a jack (not shown.)
K designates an le irons attached to the uplper outer sides o the mold sections A and w ich support the floor joists L, said floor joists being also formed of angle irons. The angular metallic floor panels M are supported upon the joists L at the adjoining ends of said panels, and the ends of said anels that abut with a irder are supporte upon the angle irons Where there is a concrete beam, the panels M are supported upon joists L which extend between parallel beams and the ends of which rest u on the an le irons K of the sections A of the eam mol or molds.
N designates vertical an le irons forming the four rounded corners of t 1e column molds, the sections O are the vertical walls of the column molds and these are united to the corner pieces N b flanges and bolts e similar to the manner o uniting the sections A A of the girder and beam molds. All the bolt openings are preferably two inches from centers to centers. There is a column mold or form united to each end of each girder form or mold by angle irons and bolts. In Fig. 1, only one of the column molds is shown as united to one end of the girder form or mold. The column molds communicate with the ends of the girder molds a distance equal to the depth of the girder molds, the ortion or portions of the column molds elow the girder molds being inclosed on all sides.
P desi nates adjustable sections in the girder mo ds at points where the beams intersect.` These ad'ustable sections may be raised or lowere to suit the required depth of beams by bolts; these sections P are attached to the sections 1A by bolts c which pass through the angle irons B. i
In the use of my im oved universal metal concrete form for rein o ced concrete Work, I preferably put the column forms in position rst, joining the girder forms thereto, and next, the beam forms are assembled in position, and the joists and floor panels are then placed in osition. The concrete is .then poured to orm the columns, girders, beams and Hoor for the first Hoor, the concrete for the ioor being of suitable thickness. The concrete is then permitted to stand in the forms or molds until properly set, after which the forms are separated and are re-assembled in the same manner to lay the next section or floor, and the same o eration is repeated until all the floors are laid'.
\ It will be understood that theI columns are extended as each Hoor structure is completed and when the entire series of floors are laid, the columns each become practically one integral piece throughout the height of the structure.
I claim:
v1. In a mold for concrete ioor construction, girder and beam molds intersecting each other and united by vertical an le irons, horizontal angle irons to which sai vertical angle irons are adjustably connected and whereby different Widths of beams and girders are obtainable, tie rods connecting the vertical and horizontal angle irons, turn buckles interposed between the ends of the tie rods, brackets adjustably connected to the horizontal angle irons and whereby said brackets may be adjusted vertically, and mold bottoms supported on said brackets, substantially as s ecified.
2. In a mold or concrete fioor construction, girder and beam molds intersecting each other, the sides of said molds being joined by vertical angle irons, horizontal angle irons to which the vertical angle irons are adjustably connected and b f means of which connections the widths o the molds ma be increased to obtain different widths o beams or girders, adjustable brackets lying within the molds, said brackets bein ad] ustably connected to the horizontal ang e irons, and mold bottoms supported upon said brackets.
In testimony whereof I aiix my signature, in presence of two witnesses.
