To all whom c't may concern.'

Be it known that I, SIMON LAKE, a citizen of the United States, residing at Milford, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Concrete Building Construction, of which the following is a. specification. The primary intent of this invention is to devise a fire and moisture proof building of novel structure, as well as method of formation, which is free from joints and not susceptible to the deleterious action of settling, since it particularly involves a onepiece structure securely braced, stayed, and reinforced in every direction. The invention relates to a structure o concrete, or like self-hardening building material, fashioned by a mold-and strengthened by reinforcements embedded in the material at the time of molding the same.

The invention contemplates a mold and a core disposed within the mold and formed of some fusible material, suchv as paraflin', asphalt, or a combination of elements providing a composition which may be softened and caused to flow by the action of heat, the

spaces formed betweenthe core and the mold being`illed with concrete or like plastic building material, as are more fully set forth in the following description, illustrated in the accompanying drawings, and

` hereinafter more particularly claimed.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated Figure 1 is a vertical section of a building having all parts in place, afterthe body forming material has been supplied to the mold, and with the core and core fusing means still in position. g

Fig. 2 is a view similar to Fig. 1 showing more particularly the tubular reinforcement which may be utilized to prevent expansion or for other purposes, the mold being removed.

Fig. 3 isan enlarged cross sectional detail.

Fig. 4 is a`view similar to Fig. 3 having the plates o1' lelements comprlsing the mold moved outward to provide spaces for re-l ceiving the material forming the finishing coat. A

Fig. 5 is a detail view-cfa lportion Aof the reinforced means. Fig. 6 is a sectlon of the reinforcing means shown in Fig.' 5, taken at right angles l core showinga plurality of lblocks or elements properlyl arranged.

Fig. 10 is -an elevation of part of the reinforcement, core, and centering and holdingmeans for such parts.

Fig. 11 is a view similar-to Fig. 8 of a further modification.

In carrying out the invention, a mold is a necessary adjunct, since it givesrproper shape to the concrete or other self-hardening plastic material utilized in the formation of the building or like structure. This mold may be of any nature, and comprises plates or elements which are spaced apart ,the required distance and so disposed acafter which the mold is removed. As indicated most clearly in Figs. 3 and 4, the" mold forming elements, or plates 1 and 2,

are connected by means of ties 3, and are'l held apart lby spacers 4, the latter being mounted upon the ties and coming between the plates or mold members 1 and 2. The

ties 3, preferably consist of threaded rods,

and the spacing elements 4 consist of tubing of proper length, the same being slipped upon the ties so as to come between the mold elements. *,Thimbles or collars 5 are mounted upon end portions of the ties, and constitute means whereby the plates or mold members 1 and 2 may be moved outward a short `distance from the opposingfaces of the structu-re to providespaces for receiving the material desired to form the finishing coat to the walls. These thimbles or collars may be of any formation to admit ofthe purpose being accomplished.v -Adjusting nuts 6, mounted upon the threaded ends of the tie'- rods 3, engage the mold members 'land 2 more or, less directly, and hold the same the required adjusted position.

,. and of a shape to conform to the structure been completed, a portion of such materialy mold isl being set up. The core is indicated at 7, and preferably comprises aplurality of fusible blocks or velements of any desired size for convenience of handllng,

to be built. This core may be of any material adapted to be affected by heat so as to be 'reduced to a liquid state, whereby it may liow from the structure after the same has permeating the inner walls of the structure,

' and coating such walls to render them moistureproof. 1t is proposed to utilize parafn, asphalt or a composition ofelements to produce the material employed'in the formation of the core.

shape, and such blocks or elements are disposed within the mold to provide spaces at the sides of the core for receiving the spacers and ties, and such openings being of a size to receive portions of the building material, whereby the spaced walls are united by bonds or ties. As indicated in Fig. 7, the

. corners of the blocks or elements comprising the core are cut away so that when the blocks or core elements are in position, openin s are provided to receive the s ace-rs t an ties 3, and portions of the buil ing material forming the bonds or ties, whereby the spaced parts of the walls are connected. Reinforcements 9 are arranged in the spaces formed between the core 7 and the mold members, or plates 1 and' 2. rlhe reinforcements 9 may be of any nature generally employed inv structural formations of concrete or like material. The reinforcements may consist of rods, wire fabric, or like well known means. It is to be understood that the reinforcing means 9 is so disposed as to become embedded in the building material, and may be held in position in the mold in any desired or convenient way.

Fig. 2 illustrates a tubular framework l0,

the same conforming to the mold space and occupying a central position therein. The tubes or pipes comprising the framework 10 may be of any size and are coupled by means of fittings in a manner well understood. The framework 10 provides supplemental reinforcing means, and being of tubular formation provides for the circulation vof a cooling medium therethrough, and the Such material is molded into elements or blocks of desired size and poses, or for carrying of waste from water fixtures, or may provide conduits for any urpose whatsoever. The framework l0,

y reason of its lformation, is self-'supporting, and may be utilized as sustaining means for the reinforcing means 9, particularly when the latter consists of wire fabric, the latter being attached to the elements of the framework 10 substantially as indicated in Figs. 5 and 6. By circulating a cooling medium vthrough. the framework 10 undue expansion of the structure is prevented when applying heat to liquefy the core, so that the same may flow ofi", and, at the Sametime, coat the .inner walls.

Heating pipes 11 are disposed in the mold, preferably at equal distances from the mold plates or members 1 and 2, and extend vthrough the core 7. The pipes 11 are designed to receive a heating medium such as steam, the latter being supplied thereto when itis desired to liquefy the core, as when the structure Ais otherwise completed and becomes set. The heating medium may be supplied to the pipes 11 from a suitable source in any convenient and desired way.

same may be utilized for. Ventilating. purl. I,

The pipes l1 are provided in sufficient numture and mold for the e-Xit of the material v are formed in the lowerv portion of the strucwhen the same is flowing. Theheating pipes 11 are removed after the core has been melt,- ed and caused to flow off. In this respect the heating pipes 11 differ from the tubular framework 10,'which becomes a part of the structure, since said tubular frame-work is utilized as reinforcing means in the manner hereinbefore stated.

In the modification illustrated in Fig. 8, ties 14 serve to connect oppositely disposed reinforcements, 9, and these ties 14 may be of any desired structural form. Fig. 9 shows concrete elements 15 of a length to fit between the spaces 1 and 2, and formed with' central enlargements 15a. Wires 15b are molded in the elements l5 and their ends engage the reinforcements 9.

1n accordance with the invention, .the tubular frame is first set up, one wall of the mold fis then set up as a preliminary step and thev reinforcing and core means are placed in position, after which the building material, such as concrete, or other similar plastic self-hardening material is supplied to the mold spaceto ill the same, and

after such material is hardened or set sufficiently to permit of the mold being removed with safet such mold may be detached ifv the walls of the structure are to be finished in any of the usual ways by troweling, or if such walls are to be coated by a finishing material flowed thereon, the mold plates or elements 1 and 2 are loosened and moved outward so as to leave a relatively small space between the opposing sides of the concrete structure and the mold elements into which plaster of Paris, cement, or other finishing material may be flowed. Fig. fl illustrates thev mold plates or elements 1 and 2 moved outward from the walls of the concrete structure, leavingl spaces for the reception of a finishing coat 16, which is flowed into such spaces. Because of the relatively small dimension of the finishing coat spaces, the finishing material may be caused to flow into and to completely fill such spaces by jarring or vibrating the mold plates as by delivering blows thereon, or by tamping the material as it is fed into the mold.

The concrete material forming the structure is indicated at 17, and comprises s aced parts which are joined by means of onds or ties 18 (Figs. 3, 4, 7, 8, and 11) constituting portions of the building material, which have passed through the openings 8 of the core when filling such material into the mold. After the concrete material has set, the cores 7 are removed by the application of heat, the same causing the material to melt and fiow through the outlets 13. The heat is applied and didused throughout the structure by means ofthe heating pipes 11 through which the steam or-other heating medium is'caused to fiow. When the core is reduced to a liquid state, a portion of the material permeates and coats the inner Walls of the structure border- .ing on the core space, thereby rendering such walls moisture-proof and preventing dampness passing therethrough from the outside. The material forming the core having been recovered, may be used in further operations, or in any desired way. During the fusing of the core, and to prevent undue expansion of the structure and the metallic reinforcements thereof, a cooling medium is circulated through the tubular framework 10, such cooling medium usually consisting of water, although it is to be understood that air or other fluid may be advantageously employed. After the core has been removed from the structure, the heating pipes 11, not being required for further service, are withdrawn.

If it be required to supply fire clay or like material to the spaces previously. occupied by the cores, such material may be liowed -into the core spaces, and in the event of the Structure being subjected to eX- lvide a thoroughly rigid structure.

cessive heat to such an extent as to cause the exterior walls to crack, the inner layers of fire clay or like material will sustain and prevent serious damage, or a collapse of the building. This inner filling of fire clay may be rapidly dried by the application of heat, which may be supplied through the pipes 11 before the Withdrawal of such pipes from the structure.

The tubular framework 10 may be utilized in different ways as hereinbefore indicated, and if required, the same may be filled with concrete or like material which will result in the provision of an additional reinforcing means, and, at the same time, prevent tlie interior of the pipes from being corroded by dampness.

It is proposed to form the structure as a whole in one-piece, including the exterior walls, partitions, fioors, and roof, hence the building is not liable to suffer injury from settling, and, at the same time, is proof against dampness and from the action of the elements, as there are no joints to open and admit currents of air, or to produce weakness in the building.

l't will be understood from the foregoing that l provide a building structure which is strengthened and relinforced by a framework susceptible of use for carrying ofil noxious odors, vapors, or gases, or for supplying pure air, or as means for carrying off waste from water fixtures of various kinds, or as conductors for supplying water, or gas, or for receiving electric wires, or for carrying steam or hot water to radiators for heating purposes.

rlhe elements 15 are formed of concrete and have the wires 15b molded therein. The ends of the wires 15b project to engage the reinforcements 9 and hold them in the required position in the mold spaces at the sides of the core. The annular enlargements 15L of the elements 15 enter corresponding openings formed in the core sections and hold them in the desired position and prevent any lateral displacement thereof. rlhe ends of the elements 15 may be corrugated as shown at 15C, or otherwise formed to insure positive association between the elements and the spaced portions of the walls. The elements 15 serve as centering and holding means both for the cores 7 and the reinforcements 9.

ln the arrangement of the elements 15, it is not necessary that the same be disposed between every two sections or blocks of the While I have shown horizontal members 10a connecting the framework 10 at the joints thereof, 'it will be well understood that -additional horizontal connections may be made at various points in order to pro- It will also be understood that transverse fabric members 9 may be arranged in the ceiling,

the vertical members of the framework 10 are not only thoroughly braced, but the said Afabric members also sustain the weight of the material forming the lioorand roof sections of the building. l

- The centering and holding members 15 for the cores 7 and reinforcements 9 may be molded of any material, concrete being preferred, and may be of any size as to diameter and length, but it is essential that they correspond in length to the thiclmess of the wall or like part of the structure, so as to engage the opposite mold members 1 and 2, and properly space or hold the cores and reinforcements in the required .relative position. The ends of the wires 15" project through the sides of the members 15 to any distance, as indicated at 15d, to make positive engagement with mesh elements or other desired members of the reinforcements 9 as may be required or found most convenient. In the modification shown in Fig. 11, the reinforcements 9 embedded in the spaced side portions of the wall structure, or like part, are connected by means of ties 9 which are preferably embedded in the concrete bond or tie portions 18 of the building structure. These ties 9a are secured to the reinforcements 9 in any convenient and substantial Way. v

-It will be further understood from the construction illustrated in Figs. 9 and 10 Vof the drawings, thatA where the -holding members 15 are employed, the ends of the l wires 15b will be of sufficient length to permit the ends 15d thereof to be wra ped around or anchored to the adjacent horizontal or vertical strand of the wires of the reinforcements 9, hence facilitating lthe anchoring of the elements 15 within the material 17 constituting the walls of the building. It will also be further under: stood lthat by providing the members 15 with annular enlargements 15, the .fusible blocks 7 will be provided with corresponding recesses to receive the said enlargements, thereby facilitating the arrangement of the fusible blocks or core members 7 into position within the mold, or plates or elements l and 2, and hence facilitating the adjustments of the core members. 7 in vertical alinement with 'respect to the plates or elements 1 and 2.

ous modifications may be made without departing from the broad idea of my invention I have described and illustrated the broad idea of providing troughs 12 at the base of the building. for collectin the fusible material (forming the mol s of the Walls, ceilings, and floorings of a bulldmg), at the base of the walls, but it will be distinctly understood that similar troughs 12 may be arranged at various points upon 'the sides of the walls or below and adjacent to the floorings, or ceilings of the building ,as might be suggested to anyone skilled in the art to which my invention relates.

It will be further understood that the pipes 10 will be provided with suitable connections such as is shown at 10", in Fig. 2,. for flooding the same, and that suitable connections (not shown) will be provided at their lower ends for draining the water flooded or led into said pipes, but as the latter connections will be readily understood, it is not thought necessary to illustrate them or to describe them in detail.
