WILLIAM J. MATTHEWS, OF CHICAGO, ILLINOIS.
Specification of Letters Patent.
Patented Jan. 11, 1921.
Application filed January 12, 1920. -Seria1 No. 350,751.
To all whom it may concern:
Be it known that I, WVILLIAM J. MAT- THEWS, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ceiling Construction for Reinforced-Concrete Buildings, of which the following is a specification, reference being bad to the accompanying drawings.
In reinforced concrete construction the flooring, (and occasionally walls), comprises a comparatively thin body of reinforced concrete integral with heavy bodies which are positioned in spaced relation to form beams, and to the under side of said beams ceiling boards (or metal lathing), are secured in determined relation to said beams, and to said ceiling board plaster is applied.
This invention relates particularly, to means whereby ceiling boards, or metal lathing, are attached to reinforced concrete beams.
Among the objects of this invention is to obtain cheap, effective and durable means of attaching ceiling boards, or metal lathing, to beams of relnforced concrete; a further object is to obtain means which are readily understood and installed by tradesmen or mechanics who are unskilled in the trade or calling of the workmen who con struct or build up the means embodying this invention. Additional objects are to obtain means of the kind described which may be handled and installed by mechanics of several different trades unions, without interfering with the rules or regulations of said unions.
In the drawlngs referred to F lgure 1 IS a cross section of a portion of a reinforced floor or wall, provided withbeamsin spaced relation integral therewith; and of ceiling boards, with plaster thereon, attached thereto by means embodying this invention.
Fig. 2 is a cross section similar to F 1g. 1, of the same parts, illustrating a modification of the means embodying this invention Fig. 3 is a cross section of the parts illustrated in Figs. 1 and 2, with an additional modification of the means embodying the invention;
Fig. 4, is a view, looking up, of a section of a reinforced concrete beam, with p0rtions of a pluralityof'ceiling boards attached, by means embodying this invention. Fig. 5 isa cross section of a reinforced concrete floor or wall, with a beam of reinforced concrete integral therewith, of the form for laying said'concrete, and an end televation of means embodying this invenion.
Fig. 6 is a view similar to Fig. 5, illustrating a modification of the means embodying the invention.
Fig. 7 is a section on line 7-7 of Fig. 55, viewed in the direction indicated by a1- rows.
Fig. 8 is a top plan view of a section of a construction comprised in the embodiment of this invention.
Fig. 9 is a side elevation of the section illustrated in Fig. 8; and
Fig. 10 is an end elevation thereof.
Fig. 11 is a top plan view and Fig. 12 a side elevation of a modification of the construction illustrated in Figs. '8 and 9.
And Fig. 13 an end elevation of an addi' lilOlZLl modification of said construction; an
Fig. 14 is a bottom plan view of a section of ceiling board attached by means embodying this invention, showing adjacent ends and adjacent sides of said boards.
A reference character applied to designate a given part indicates said part throughout the several figures of the drawing wherever the same appears.
represents reinforced concrete flooring, and Y beams which are integral with said flooring.
A represents a stri of sheet metal, which I term a guide. 1333', C, C and C", respectively represent strips of metal, which are secured to guide A, as by spot welding. Strips B, B, are hereinafter termed embedding strips; and strips C, C, C", are termed supporting strips.
D, D, Figs. 8, l1 and 14, are broken lines which indicate the edges of the spot welding which joins members A, to members B, (or B), and C, (or C C"). E, E, represent ends of members 6, (or C, C"); said ends being bent as hereinafter described, to attach or secure plaster board (F, F), in place. G, G, Fig. 8, represent apertures in the supporting strips, through which apertures, when desired, a pin or bolt (H, Fig. 2), may be extended. J Fig. 3, represents a strip or rod which is attached at its upper end to supporting strip C, and at its lower end to an additional supporting member, ((J), by bolts I, I. K, Figs. 1 and 2, represent plaster, on the under side of plaster boards F, F.
In Figs. 5, 6 and 7 the forms by means of which a reinforced flooring with beams is made, are illustrated; and in said figures L represents the base or form supporting the flooring until it sets; and M, M, the sides, and N the bottom of the trough by means of which the beams are obtained.
The several embedding and supporting members being secured to the guide member. by spot welding, and in the relative positions illustrated in Figs. 8, 9, 10, 11, 12 and 13, (as preferred) said members are placed in the beam trough, with supporting members C, (or C, C), resting on bottom N thereof. The embedding members 13, (or 13', Figs. 11 and 12), are then bent up, so that when the reinforced concrete which ultimately forms the beams Y, Y, is deposited in the trough, said embedding mem bers are embedded in said concrete.
The plaster board supporting members C, (or C, C) resting, as recited, on the bot tom of the trough and said concrete mixture being run thercinto in the ordinary way, it will be deposited on the top and at the sides of said members; but will not cover said members to hide them from view. This occurs when said supporting members are so long that they extend up the sides of the trough, as is illustrated in Fig. 6. The guide members being supported by the supporting members the concrete mixture will extend on, around, and underneath said guide members, completely embedding them in said concrete. This is particularly so when the guide member is spot welded to the embedding and supporting members in the relation illustrated in Fig. 13; as in such case the thickness of the concrete mixture under the guide member is equal to the thickness of the embedding member and the supporting member, combined. Should the guide member be exposed on the under side thereof the effectiveness of the invention is in no way impaired, as the function of the guide member is completed prior to the deposit of the concrete mixture in the trough.
When the flooring and beams have become set in the ordinary way, and the forms (comprising members L, M, M and N), are removed, the supporting members (C, or C, C) are so exposed that they may be bent down, into the positions which are indicated by broken lines in Fig. 13.
In Figs. 2 and 3 what is termed in the trade a suspended ceiling is illustrated. In Fig. 2 the supporting members C are of suflicient length so that when bent down into a vertical plane, they reach below the ceiling boards F, F, and are bent adjacent to the end part to obtain parts E, E, in a horizontal plane. The pin H of any suitable length is inserted in apertures G, G, before the plaster boards F, F, are positioned, so that when plaster (K), is applied to the under side of said boards. said pins hold said boards down, (in place), during said application.
In the suspended ceiling which is illustrated in Fig. 3, there is a considerable distance between the plaster boards F. F, and the bottom of the beams Y, Y, and a strip (J), of heavy sheet metal (or rod), is used. Additional strips C, C, are attached to the lower end of strip or rod J, and said strips are bent to obtain parts E, E, in a horizontal plane, supporting the plaster boards F, F. The bolts I, I, and the bends in said supporting strips, above the plaster boards, prevent said plaster boards being forced upward when plaster is being applied thereto in the ordinary way.
I claim;
An article of manufacture comprising a longitudinal strip adapted to lie in a beam of reinforced concrete adjacent the form thereof, with strips united thereto and in angular relation to said longitudinal strip, some of the latter strips being adapted to be bent up to form anchorage members and others of said strips being adapted to be bent downwardly to form supports for plaster board.
