UNITED STATES HENRY SORENSEN, OF SAN FRANCISCO, CALIFORNIA.

CONSTRUCTION OF FIREPROOF BUILDINGS.

Application filed May 18,

My invention, herein, consists of a novel and simple device, .by which I apply the principle of the wedge to stretch and interlock the reinforcements with the supports of the infilled structure, and while my invention may be utilized in arious ways, I have described it applied to fireproof floors.

In the accompanying drawings, where similar numerals indicate similar parts;

1 illustrates my invention before the wedgi 1g of the reinforcement, against the support of the infilled structure, has taken place.

Fig. 2 illustrates my invention after the wedging of the reinforcement, against the said support, is done.

Fig. 3 is a plan view of my invention showing the reinforcements in place, and ready to receive the infilling.

Numerals 1 designate the reinforcements. Numerals 2 designate hooks which hold reinforcements 1 to beams 3. Beams 3 support the floor, and numerals 4c are columns which, in turn, support beams 3. Numerals 5 designate wedgeshaped elongations attached to reinforcements 1. Numeral 6 designates the place, on beam 3, against which the wedgeshaped elongation 5 is driven. Numeral 7 is the end of the wedgeshaped elongation 5.

Reinforcements 1 may be of any suitable design; I attach, at the one end of reinforcements 1, hooks 2, which hold reinforcements l firmly to beams 3. Between beams 3, and under reinforcen'ients 1, I place a horizontal form (not shown) upon which the fireproof infilling is laid. The fireproof infilling, together with the reinforcements 1, forms the floor, and beams 3 serve as supports for this floor, while columns a, in turn, support beams After having described the above I am now coming to that which constitutes my invention, herein.

In order to stretch and interlock reinforcements 1 with beams 3, I add the wedgeshaped elongations 5, to reinforcements 1, at the opposite ends to hooks 2.

In Fig. 1 I have shown that the length of reinforcement 1 just allows end 7, of the wedgeshaped elongation 5, to clear beam 3 at 6. Due to the fact that the angle, between wedgeshaped elongation 5 and rein- 1926. Serial No. 109,891.

forcement 1, is not less than 90, and that hook 2 is firm with the opposite beam 3, the wedgeshaped elongation 5 will, when driven, be wedged against 6, and consequently stretch and interlock reinforcement 1 with. beams 3. If said angle had been less than 90, reinforcement 1 would have dropped loosely on beam 3, after the end 7, of the wedgeshaped elongation 5, had passed 6.

Fig. 2 shows reinforcement 1, stretched and interlocked with beams 3, after the wedgeshaped elongation 5 is driven, and 5i 3 gives a plan view of the reinforcements 1, in place, and ready to receive the infilling. When member 5 is driven the point 7 of 5 is llgi-enlti in, thereby preventing 5 from slipping I make reinforcement 1 a suitable fraction shorter than the distance between 6 and the point where hook 2 contacts beam 3. Reinforcement 1 may, thereby, be stretched the length of said fraction, when elongation 5 is driven against 6 of beam 3.

The simplicity of my invention facilitates a great saving in labor, as well as a saving in wedgeshaped material.

Other modifications of construction may be made without departing from the spirit of my invention.

I claim 1. In a reinforcement of an infilled structure spanning spaced flanged beams, the combination of means for attaching the one end of said reinforcement to a portion of one of said beams and the other end of said reinforcement bent to form a wedge-like member to engage the flange on the opposed beam, whereby said reinforcement is initially tensioned and wedged to said beams when said member is driven.

2. In av reinforcement of an iniilled structure spanning spaced flanged beams, the combination of a hook at one end of said reinforcement engaging the flange of the one of said beams, and the other end of said reinforcement bent to form a wedge-like member to engage the flange of the opposed beam, whereby said reinforcement is initially tensioned and wedged to said beams when said member is driven.
