MEANS FOR MAKING FLOORS, ROOFS, AND TI IE LIKE.

Application filed November 5, 1915, Serial No. 59,828. Renewed May 20, 1919. Serial No. 298,555.

To all whom it may concern:

Be it known that I, ALBERT A. PAULY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have'invented new and useful Improvements in Means for Making constructing floors, roofs, and the like bythe use of forms or molds, either permanent or removable, whereby cementitious material may have ready access to the under surfaces of beams, girders, or the like, which initially support the said forms or molds and finally the completed floor, roof, or the like. Prior to my invention, it has not been the practice to provide beam or girdersupported forms or molds with any molding portions to receive cementitious material from above and form a cement covering for the lower sides of the beams or girders. It is required by fire insurance companies that the metal beams and girders which support the floors and roofs shall be coated on their lower sides with cementitious material which serves as a barrier against fire obtaining direct access to the metal and causing its distortion and the collapse of the floors or roofs supported by the said beams and girders. My invention provides a satisfactory means for accomplishing the objects aforesaid.

Referring to the accompanying drawings,

Figure 1 is a fragmentary view, showing in cross-section one form of my improved floor construction; Fig. 2, a plan of Fig. 1, with the cementitious material omitted from the right-hand mold space; Fig. 3 an enlarged view showing the supporting bars or girders of Figs. 1 and 2 in combination with a combined hanger for the tiles-or forms and a spacer for the bars or girders; Fig. 1, a modification of'Fig. 1, with a metal form substituted for the tiles; and Fig. 5, a plan of Fig. d with the cementitious flooring omitted.

Referring now to Figs. 1, 2, and 3, I show the beams or girders in the form of plain rectangular bars 11, though they may have different shapes. These bars 11 are arranged in pairs bet-ween adjacent tiles 3 and supported in any suitable manner. I provide a number of narrow metal barspacing and tile-supporting devices or clips 12 which .nray be composed of strong steel bar of any preferred cross-section. The clips 12 have their central portion bent to form a U-shaped spacing member having its outer sides 13 parallel and in engagement with the opposing sides of a pair of bars 11. The end portions 14 of the clip are bent back parallel with the U-shaped member, but spaced therefrom so as to engage the outer faces of the bars 11 when-the U-shaped member is in position between the bars 11, as shown on Figs. 1 and 3. The extreme ends of the'clips are bent out at right angles to the portions 14: and in the plane of the sides 13 and portions .14 to form support-s or projections 15 on which the ribs 16 on the ends of the tiles 3 rest. The tiles 3 have the flanges 6 engaging'the adjacent tile and forming mold spaces 7 beneath the bars and projections 15.

Referring finally to Figs. 4: and 5, I employ the bars 11 and the clips 12 as in Figs. 1, 2, and 3. In the forms of invention before described the forms or molds become permanent parts of the floor. In Figs. 1 and 5 I employ arched sheet-metal forms spanning the spaces between consecutive pairs of bars 11. Each form 3 has its lateral portions or sides extending downwardly and provided with outwardly extending lugs 16 resting on the supporting projections 15 of theclips 12. One side of each form 3 ext-ends below the projections 15 and terminates in the flange 6, which engages with the downwardly extending side of the adjacent form 3, the flange 6 being below the bars 11 and constituting a mold bottom for. cementitious material poured into the space between the bars 11 and the spaces between the bars and the sides of the form 3". The flanges 6 on one form are shown resting on short flanges 17 on the adjacent forms. The cement is poured so as to fill not. only the spaces adjacent to the bars 11 but so as to cover the entire forms to the depth required to form the floor 8. After the cementitious floor material has become hard the forms 3 may be removed with free ends arranged in a series lengthwise of the supports and that the forms rest on the free ends of consecutive pairs of supports.

I claim 1. In a reinforced cement construction, spaced supports, each comprising a pair of parallel members, a series of clips arranged on each pair of members, the clips havlng a U-shaped central portion arranged to space the members "of each pair, and downwardly-extending portions engaging the outer faces of the pair of members, and horizontal terminals pro ecting'away from the said member, and forms arranged between consecutive pairs of supports and rest ing on the said terminals.

2. In a reinforced cement construction, spaced supports, a series of narrow clips with horizontal outwardly-extending free ends independently hung on the supports, and forms arranged between the supports and supported by the said ends, the sides of the forms meeting a short distance beneath the su ports, whereby molding spaces are forme and at opposite sides thereof.

Signed at Cleveland, 0., this 2d day of November, 1915.

ALBERT A. PAULY.
