SPECKFICATION forming part of Letters Patent No. 678,365, dated July 16, 1901. Appiicaionneanugusm,1900. sannita. 27,541. (No man.)
To all whom t may concern.-
Be it known that I, GEORGE H. KUNNEKE, acitizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Centering-Supports, fully described and represented in the following specification and the accompanyingdrawin gs, forming a part of the same.
This invention relates especially to the construction of ireproof iioors, ceilings, arches, and similar structures in which a temporary framework or centering is used to support the material of the structure during the making of the same and during the setting of concrete or other plastic material, if such plastic materials be used, the object of the invention being to provide a simple, cheap, and efficient means of supporting the centering in place and enabling the centering to be quickly and conveniently placed in proper position and removed.
As the invention can best be understood by a description of a construction embodying the same, such a description will now be given in connection with the accompanying drawings, forming a part of this specification, and in which theinvention is shown as applied in .connection with the construction of two fireproof ioors of different forms, and the features forming the invention will then be specitically pointed out in the claims.
In the drawings, Figure 1 is a section transverse to the beams of aV concrete ireproof oor in process of construction with the centering in place. Fig. 2 is a section at right angles to Fig. 1. Fig. 3 is a section similar to Fig. 1, showing the completed construc-l tion with plaster finish. Fig. 4 is a view similar to Fig. 1, showing another form of iloor. Fig. 5 is a detail of one of the beams of Fig. 1, showing the operation of putting the centering in place.
Referring now especially to Figs. 1 to 3 and 5, A are the beams between which the floor or other structure is to be built, these being shown as of the common I form, although it will be understood that this is immaterial so far as the present invention is concerned. Over these beams are put hangers B, which consist of pieces of wire or similar metal of suiiicient strength to support the load desired, the ends of these hangers projecting below the beams and on opposite sides of the centering-bars C, which extend below and at right angles tothe beams. Upon these centering bars C is supported the y centering proper, which in the form shown in Figs. 1 and 2, which is the preferred form for arched structures, consists of cross-pieces D, secured on and above the bars C, being preferably secured to the latter by cleats E, nailed to the bars and cross-pieces, as shown, this being a simple and cheap construction, while at the same time enabling the centering to be raised' to any desired level above the bars C with the same cross-pieces D by securing the cross-pieces more or less above the bars C. Upon the cross-pieces l) is the moldboard or centering proper, which is shown as formed of boards F, laid side by side upon the crosspieces D and extending,longitudinally of the beams.
The bars C may be first secured in place and the centering then built thereon, or the centering structure may be built complete and then placed in position. ln either case the bars C are secured in place and properly positioned to be supported by the wire hangers B in the following manner: The bars C, with or without the centering structure thereon, are supported in position below the beams and the wire hangers B placed in position over the beams, with the lower ends on opposite sides of the bars C, so that when the lower ends of the hanger are brought together a loop will be formed inclosing the bar C. lThe ends of the wire hangers are then twisted together, bringing the lower ends of the hangers from the position shown in dotted lines in Fig. 5 to that shown in full lines in the same gure, and then a twisting-bar Gr is passed through the loop of the-hanger and the wires twisted into the form shownin Figs. 1 and 2, thus drawing the bars C up tight against the lower flanges of the beamsl andv securely locking them in place by the twists of the wire, a firm rigid support for the centering thus being provided and the proper position of the centering relatively to the beams assured. The centering `thus having been placed and secured Ain position, the iill- IOO ing II, of concrete or similar plastic material, as shown in Figs. l and 2, is filled in on the centering. When the concrete has set suiiiciently and the centering is to be removed, it is necessary only to cut the wire hangers at the lower anges of the beams, which en-l tirely releases the centering for removal. The ordinary plaster finish usedin such structures will then completely cover the-lower ends of those portions of the Wire hangers left in the concrete, as shown in Fig. 3, or the same concealment of the ends of the hangers may be secured in any other manner or the ends left exposed.
In Fig. 4 my improved centering construc-` tion is shown in connection with a flat floor formed of previously-molded blocks I and the ioorproper, K, thereon, which may be formed of plastic material or wooden ilooring or otherwise, as desired. In this construction shown in Fig. 4 the mold-frame formed of the boards F is built directly upon the centering-bars C, the bars C being dropped below the anges of the beams and positioned for placing the blocks I in proper position thereon. In this construction the centering is placed in position and removed in the same manner as previously described in connection with Figs. l to 3, and the lower ends of the hangers B will be concealed by the finish of plaster usually applied on the bottom of the blocks I in such floor constructions.
It will be understood that the invention is applicable not only in connection with building concrete, brick, tile-block, or similar structures, but also in all other structures, either permanent or temporary, in which it is desired to support material by a temporary centering. It will be understood also that the inveution,considered broadly, is not limited to the use of constructions in .which the centering is drawn up and secured in place by twisting the hangers, as shown and described, nor to the use of hangers of Wire or similar construction adapted to be thus twisted, as metal hangers may be used without this twisting feature and the centering drawn up and secured in place in a dilerent manner. The constructions shown employing the wire hangers twisted to draw up and secure the centering are claimed specitically, however, although not essential to the broader features of the invention.
What I claim is-` 1. The combination with beams or the like and a centering, of metal hangers extending over the tops of the beams and forming loops inclosing a temporary part of the construction below the beams by which temporary part the centering is supported, said hangers being adapted to be cut to release the temporary part for the removal of the centering, substantially as described.
2. The combination with beams or the like, of temporary bars C extending below the beams and transversely thereto, metal hangers B extending over the tops of the beams and about the bars C to support the latter and centering carried by said bars, substantially as described.
3. The combination with beams or the like, of bars C extending below the beams, metal hangers extending over the beams and having their lower ends inclosing the bars C and twisted together to support the bars, and centering carried by said bars, substantially as described.
1l. The combination with beams or the like, of temporary bars C extending below the beams, Wire hangers B extending over the tops of the beams and about the bars C to support the latter and centering carried by said bars, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
