To all whom it may concern:

Be it known that I, MINOR E. CHAMBER- LAIN, a citizen of the United States, residing at Lebanon, Laclede county, Missouri, have invented a new and useful Reinforced Concrete Construction, of which the following is a specification.

This invention relates to reinforced concrete construction.

An object of the invention is to provide an improved reinforced concrete construction in which the reinforcement is composed of a section of sheet metal folded to form a triangle in cross section and having its side edges extended laterally from the apex of one of the angles of the triangle; whereby maximum strength of the sheet metal as a reinforcement is derived from the fact of its angular formation so that one angular side or plane thereof braces and strengthens all the other sides or planes.

Another object of the invention is to provide an improved sheet metal reinforcement characterized and constructed as described in the foregoing statement, in combination with means for connecting abutting reinforcements in longitudinal series, whereby the several sections of reinforcements are in effect a single reinforcement strengthened by the connecting parts.

Another object of the invention is to provide reinforcements constructed and characterized as stated, capable of use for the reinforcements of any concrete construction, such for instance as posts, columns, walls and the like.

Various other objects and advantages will appear from the following description in which reference is made to the accompanying drawings, illustrating the invention in which Figure 1 is a view illustrating the forms of the reinforcements adapted for use in the construction of concrete buildings, and walls including the flooring thereof.

Fig. 2 is an enlarged sectional view illustrating one of the reinforcements in use as a floor beam.

Fig. 3 is a perspective view illustrating the connecting device by which alined, abutting reinforcing sections are connected together.

Fig. 4 is a plan view illustrating the reinforcements connected together to serve the functions of studding any concrete walls.

Fig. 5 is a horizontal section through a corner section of a wall structure illustrating the reinforcements for the side walls embedded therein, and also showing the form of reinforcement for the angle section at the point where the walls meet.

As illustrated the walls include an inner series of upright reinforcements and an outer series of upright reinforcements. The inner and outer series of reinforcements are connected together by strengthening the connections so that they are held equally spaced and in right relation in respect of each other.

Each reinforcement is composed of one or more sections of sheet metal folded to provide a triangular reinforcement comprising a base or face wall 1 and two side walls 2 preferably of substantially equal width with the wall 1, and each folded laterally to provide the laterally extending wings 3. In the form illustrated the wings 3 are in planes parallel with the plane of the wall 1, though it is obvious that the angle of the wings 3 may be otherwise arranged wherever a different conformation is desired.

The studding comprising the reinforce ments thus constructed is placed so that the walls 1 of the outer series are outwardly and the walls 1 of the inner series are inwardly to provide plane faces against which the laths 4 are placed. The inner and outer series of studs are rigidly united by reinforcing connections comprising the connect ing plates 5 riveted or otherwise attached together and having their ends bent and folded to provide engaging brackets 6 which engage and clamp upon the laterally extending wings 3 of the studs. Thus the studs are rigidly braced and strengthened and held from relative movement.

The laths 4 may be attached to the studs by any suitable fastening devices. I have illustrated two means of fastening the laths to the studs, one of which comprises nails 7 driven through the laths and through the walls 1 of the studs and between the meeting edges of the walls 2, as illustrated in Fig. 4. Preferably the nails are of such length that the ends thereof may be bent laterally so that theycannot be easily withdrawn as will be clearly understood by reference to Fig. 4. Another form of attaching the laths to the studs consists of cutting the studs to provide clamping tongues 8 mensions.

which constitute supportsfor the laths and which may be clamped upon the lathe as illustrated.

Two or more alined, abutting reinforcements may be connected together in any cas in which a sin le section is of insufiicient length. An effi cient form of connecting device is illustrated in Fig. 3 and consists of a section of sheet metal folded in triangular form and of such size that the ends of the abutting reinforcements may be received therein, with the wings 3 of the abutting reinforcements outside of the wings 9 of the connecting member. The edges of the wings 9 are folded inwardly to form clamps 10 to clamp upon the wings 3 and thus give additional strength at the point of connection. When the connecting member is thus applied to two of the reinforcements clamps 11 may be placed upon the clamp wings 910 of the connecting member to hold the same compressed and clamped upon the wings 3 and thus ositively prevent the connecting member rom slipping while the concrete or other plasticmaterial is being applied.

After the reinforcements have been placed in proper position for the wall and" the laths have been attached thereto facings are made by applying layers or facings 12 of concrete or plaster to the lathe and thus producing the faces of the walls. After the concrete or plaster thus applied has hardened the intermediate space is filled with concrete and concrete is also oured into the hollow reinforcements so t at the entire structure consists of a monolithic wall embedding the hollow sheet metal reinforcements which inclose hardened concrete. Thus a very strong and durable wall structure is provided.

Obviously in the construction of posts, columns and the like, any desired number of the vertical reinforcements may be utilized and they may b connected together or not as desired. In the construction of ordinary fence posts I contemplate the use of a single vertical reinforcement composed of one or more sections, since in an ordinary post a single central reinforcement is suflicient.

In'the construction of buildings the beams may be composed of sheet metal folded in substantially the form of the vertical reinforcements though of somewhat larger di- In Fig. 2 I have illustrated a beam of suitable construction comprising a section of sheet metal folded to provide a base wall 13 and two converging walls 14 each having a laterally extending wingor flange 15 adjacent itsupper edge. Within the hollow beam thus provided may be placed a stretcher of wood 16 constitutin an engaging part for the nails 17 by whic the ceiling laths 18 are supported in place.

studs extend. Thus the floor beams constitute rigid links or connections for uniting the studding of one of th walls with the studding of an adjacent wall.

In Fig. 5 I have illustrated a corner wall section. It will be observed that the inner corner reinforcing member is formed with an angular face or base wall 21, which conforms with the inner angle of the wall structure. The side walls 2 extend from the wall 21 in the same manner as the side walls of the side reinforcing members, the side walls 2 being extended laterally to form the wings 3. The outer corner reinforcing member has an angular face wall 22 conforming in contour with the outer angle of the wall structure. The side walls 2 and the wings 3 are of the same construction as above described. The corner reinforcing members are supported together by the same form of reinforcing connections as the side reinforcements.

It will be understood that I do not confine myself to any particular dimensions, nor to the specific features illustrated, but that I contemplate variations in the arran ement and form of the reinforcements as emanded by different variations.

What I claim and desire to secure by Letters Patent, is

1. In reinforced concrete construction, the combination with an outer series of upright reinforcements each comprising a section of,

sheet metal folded to provide a hollow reinforcement composed of an outer base wall and two side walls extending obliquely inwardly toward each other from the base wall and abutting together at a distance from the base wall, and a flange integral with each of the side walls extending laterally from the line on which the side walls abut together parallel with the base wall; and a matching series of inner upright reinforcements having the flanges thereon facing said flanges on the outer series of uprights; of reinforcing plates connecting the flanges on the outer series of upright reinforcements with the flanges on the inner series of upright reinforcements and holding the side walls abutting together.

2. In reinforced concrete construction, the combination with an outer series of upright reinforcements each comprising a section of sheet metal folded to provide a hollow re- 18.

inforcement composed of an outer base wall and two side walls extending obliquely inwardly toward each other from the base wall and abutting together at a distance from the base wall, and a flange integral with each of the side walls extending laterally; from the line on which the side walls a ut together parallel with the base wall, and a matching series of inner upright reinforcements, of reinforcing plates connecting the flanges on the outer series of upright reinforcements with the flanges on the inner series of upright reinforcements and holding the side walls abutting together; and lath supporting elements passing through the base wall of the outer series of reinforcements and secured between and supported by the side walls of said outer series held together by said reinforcing plates as aforesaid.

3. In reinforced concrete construction, the combination with g series of upright reinforcements, each comprising a section of sheet metal folded to provide a hollow reinforcement composed of a base wall and two side walls extending obliquely toward each other from the base wall and abutting together at a distance therefrom, and a flan e integral with each of the side walls extending laterally from the line on which the side walls abut together, of elements engaging the flanges and holding them abutting together as aforesaid, and lath supporting elements passing through the base wall and secured between and supported by the side walls held together as aforesaid.

In witness whereof, I have signed this specification in the presence of two subscribing witnesses.
