ERNEST A. HERZBERG ANL GEORGE H. HERBERu'r. OF SEATTLE. WASHINGTON.

Frloon STRUCTURE.

Specification of Letters Patent.

latented Feb. 3, 1914-.

Application med November 25, 1912. serial No. 733,306.

Be it known that we. ERNEST A. I-lnnznne and GEORGE H. Hnnznnno, citizens of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Floor Structures, of which the following is a specification.

This invention relates to fire-proof floor and ceiling construction; and its obiect is the adaptation and utilization of the socalled plaster-boards or an equivalent, wherefrom a tubular frame is constructed to be embedded in cement, concrete or other material which is employed in the Hoor structure.

The invention consists in the novel construction and combination of parts, as will be hereinafter described and claimed.

In theaccompanying drawings, Figure 1 is a transversesectional view of a portion of a Hoor constructed in accordance With the present invention. Fig. 2 is a perspective view of a tubular form-member such as illustrated in Fig. 1. Fig. 3 is a perspective view of an element of the form-member. Fig. 4.5 is a fragmentary transverse sectional view of the preferred form of plaster-board for use in manufacturing the form-member elements.

In carrying out our invention, We employ a plurality of form-members of substantially rectangular shapes in cross 'sec- -t1on. Each of these form-members, as best shown in Fig. 2, consists of a U-shaped lower element comprising a bottom part 5 and side walls 6 extending upwardly from the lateral edges thereof; and an inverted U- shaped upper elenient comprising a-top part 7 and side walls 71 depending therefrom. The side walls 71 of the upper element are disposed to be introduced between the side walls of the lower element and are coupled together by fastcnings, such as nutted bolts 8 passing through apertures 9 and 9l provided in the respective side walls. The apertures l of an upper element are elongated to enable the elements of a member to be secured to ail'ord a depth suitable to the floor for which intended. These elelments of a form-member are constructed of plates, convcntiorutlly known as plasterboards, and is desirably comprlsedof a layer of a plastic material a, Fig. 4, interposed between two sheets b of paper, al-

though other types of plaster' board may be substituted. In the manufacture of the aforesaid elements of a form-member, the

boards are rst made on a table in the usual ported by stir-rups 13 are inserted in thespa(I between the rows of said members. Cement or concrete, indicated by 14, is then filled in between the rows ofthe members and to a distance above the tops of the latter to the height of the iioor 15, and to embed a metal web 1G such as wire luth. The cement or concrete 14 will adhere to the eX- teriors of the form-members to form a substantially homogeneous body therewith. After the structure thus far completed becomes firm, the platform 11 is removed and the ceiling plaster 17 is applied directly to the form-members and to the exposed bodies of concrete intermediate the members.

The advantages of this invention reside principally in the use of formsof minimum Weight and a maximum amour-t of adhesive properties with respect to lthe floor concrete material and ceiling plaster.

Walls or floors constructed with these devices are deemed thoroughly tire-proof by the underwriters and are recommended for use in modern buildings where the floor spaces are relatively small.

What we claim A form-member .for floor construction or the like, consisting of two opposing U- shaped elements, the side Walls of one element provided with spaced elongated openings, theside walls f the other element provided with spaced apertures registering with said openings, and clamping means extending through said openings for securing the elements together.

Signed at Seattle, lVash., this Sth day of November, 1912.
