a of which the following is a. specification.
nis invention has reference to improve nienlis in the method of constructing concrete buildings, and its object, is to produce walls wherein the greater portion of the surface of the wall is made up of thin panels of reinforced concrete, thus eeonomizing both in lahor and material in the production oi concrete huildingrs.
it has hecn practically" inrpossihle, here tol'ore, to cast a thin all of reinforced concrcte because the reinforcement interfered with the low of the concrete in the molds and irregular caslings with pits or pockets in the exposed surface of the walls, caused by the retardation of the flow of the concrete composition by the reinforcement, are found when the molds are removed.
iVhen the walls are thick of course the reinforcement does not interfere with the flow of toe cement composition, but such walls he mademuch thicker than is actually necessary.
llecause of the inherent difiieulty of casting paneled walls it is customary to make such walls oi' hollow tile or hrielc, or other material. which, in time, shrinks from the reinforced concrete columns girl, and base block, which structures may he successfully formed.
t overcome the dillieulties stated. and likewise very n'iatr-rially reduce the cost oil consl'ruetion, while still producing a perfect wall, by casting the am slalis crnist-ituling the panels in horizontal molds. A 'reiu- Iliorced concrete slah. of almost any desired thickness say from an inch to an inch and a half upward may be readily formed.
The base-blocks are cast with a groove or seat for receiving one edge oi. the panel,
ovhieli latter. after hardening. may he raised to an upright. position and he s ated in the groove in the hase. to he thoroughly anchored therein ivy cement emheddin; the. wu-respoudino edge of the panel and the projecting! porti ns oi the coinl'm'l'emenl'. lel'l' 'l'or' the pi'irpose. The side columns and lop girder may lUW l)( molded Illlllltl the sides and top of ihe panel lleing' reiu'loi'ced in the usual manner. ll this means all ihe parts are perfectly bonded, and the whi'ile structure is though molded in one solid piece. I 7
Th invention will he best understood from a consideration of the following detail description, taken in connection willrlhc accompanying (ll rings, forming" a part of this specification, in which drawings Figure l is a Yertieal cross section of a all of panel coi'istruetion built in accordance with the present invention. Fig. 2 is a detail section illustrating one of the steps in the process of construction. Fig. 51 is a vertical section lhrough i'he mold for constructing the panel. showing a panel an oni cast therein. vi finished panel, removed from the mold. land also showing inserted eve-holts, for Facilitating the handling: of the panel. Fig. 4) is an elevation of a portion of a completed structure to illustrate the Referring to the drawings. there shown a mold-box 1. which will he of a size coniinensnrate with the desired panel. and this Fig. I} is an elevalion ol a present invention.
hex provided around the edges with in ledge 2, which may he as high as the pointof reinforcement. the mold is obtained by strips 'ipplied to the ledgesfl and united thereto o dowelpins 4-. or otherwise.
he reini oreenieut illustrated as netting which may he the steel netting usually employed reinforced concrete construction, or any other type ofreinforcement suited for the purpose may be used.
The ends of the strani'ls of the reinf ment are carried through and beyond edges oi? the mold, as indicated.
After the netting has been drawn tigh a ny desired manner. the strips are hrouehc down upon the ledges 2. and engage the projeeting portions of the reinforcement, holdin; the latter in position. The cement is now poured into the mold, and eas ly finds its way through the meshes of the net-ting to the bottom of the mold, and the mold is ultimately tilled to the desired depth. thoroughly emhedding the reinforcing netting; and avoiding the formation of pockets or holes. since the composition has a minimum distance to ilow and is not iutci'lhred with lu' the drag ol the reinforcing: nel'l iue'. Thus. a pert'ect slab. of uniform thicknes through out. and of homogeneous structure with the nhedded reinforcement. is prodined. and this only he succes fully produced in Uncle The desired depth of handled bymeans of a crane or derrick, and
be readily set up on edge.
In Flg. 2 there 1s shown a base block 9, WlllCll may be as long as desired, and may,
if the length of the wall permits, include many panels. This base block 9 is formed in its upper surface with a longitudinall groovelO, wider than the thickness of the panel 6, and of such depth as to receive the lower edge of the panel for a distance and the projecting ends 7 of the reinforcing strands along the same edge.
v l l0,=then cement, or cement mortar may be poured in the groove 10. and will embed the lower edge of the panel and the reinforcement strands pro ectlng therefrom and firmly unite the panel to the base block, the
appearance of the finished structure being shown in Fig. 1. Now, by means of suitabe molds, reinforced columns ll are cast about the upright edges of the panel 6, and finally, or at the same time with the casting of the column, the top edge of the panel'is em bedded in a girder 12, which may also embed the ye-bolts 8, the said girder 12 being reinforced in the usual manner. The panel is united to the columns and girder not only by the natural adhesion of the cement, but also by the embedded ends of the reinforcing strands, as indicated in Fig. 1. The girder 19- may of course be as long as the baseblock 9, if the, complete structure admits of such length of girder, or it maybe cast in shorter lengths, if desired.
, W hen 1t is desired to form openlngs 1n the panels then the mold will be'suitably .shaped for the purpose. In Fig. 5 one of the panels 6 is shown with a door-waybpening 13, and it will be understood that other openings,
hen the slab, which is indicated When the panel has been properly located in the groove-'- such as window openings, may be likewise formed 1n the panels.
Since the panels need not support any great Weight, and since the main weight of dilliculties heretofore encountered in the endeavor to produce thin walls in the form of panels between supporting columns, is ob viated, and the necessity of using other ma tcrial, such as tiling, or brick, with the attcndant disadvantages, is entirely avoided.
It will be understolzd. of course. that the panels may be cast in any desired shape in addition to the rectangular shape shown in the drawings, and also that these panels may rary in thickness in dil'l'erent parts thereof. l urthernun'e, any desired ()llll .illtllll'tllflfll'l inay be applied, or formed directly in the mold. Also the panel may be formed with openings of any shape desired, for any purpose whatsoe er.
What is claimed is:
The herein described methodwhich conin forming'panels in the shape of slabs with reinforcing strands projecting from all the edges thereof, placing the panels on edge in grooves forn'ied in a coneertc base block, then uniting the panel and base block with cementing material introduced into the groove in the base block and about the pro jet-ting ends of the reinforcing strands, and finally casting reinforced concrete columns at the sides of the panel and a reinforced girder of concrete across the top of the panel,-
both the side columns and top girder embedding the edges of the panel and the reinforcmg strands pro ect1ng therefrom, the whole forming an integral mass.
In testimony that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses.
