Description

Feb. 5, 1935. c. G. WATSON METHQD OF REENFORCING BEAMS Filed New 25, 1951 INVENTOR.
Q? g? ArroRNEg Patented Feb. 5, 1935 UNITED STATES PATENT OFFICE 1,989,834 'ME'rnon F ansm onome BEAMS I Charles G. Watson, Youngstown, Ohio Application November 25, 1931, Serial No. 571,291
out resorting to the dismantling of the structures of which the beams are a part.
A primary object of the invention .is to provide a novel reenforced beam for use as a structural member and a novel method of reenforcing such beams.
To the accomplishment of this and-related ends, the invention, then, consists of the means hereinafter fully described and particularly pointed out in the claim, the annexed drawing and the following description setting forth in detail certain forms of construction embodying the invention, such disclosed means constituting, however, but a'tew of the various forms in which the principle of the invention may be used.
In'said annexed drawing:
. Fig. 1 isa cross-sectional view of a preferred form of the reenforced beam made in accordance 30 with my invention; and Fig. 2 is a cross-sectional view of a modified formof reenforced beam'made in accordance with the invention.
As will be seen from the drawing, each beam comprises an I-beam of usual cross-section, havinto the form shown to provide portions 2:; which are in contact with the upper flange 1a of the beam, and portions 2b which extend to the outer edges of the lower flange 1b oi the beam. Additional reenforcement for the I-beam may be provided by a plate or element 3 which is placed 5 below the lower flange or base of the beam. With the various parts thus assembled, portions of the plates 2 and 3 are made integral with the flanges of the I-beam and with each other as by welding, as indicated in the drawing. It will bereadily seen that the welding operations produce a rigid unitary beam having greater strength than the I-beam itself.
In the form of the invention illustrated in Fig. 2, the I-beam is reeniorced by means of plates 4 which are bent intermediate their edges to form diverging portions 40, which extend to the outer edges of the flanges of the beam. The edges of the plates are made integral with the flanges of the beam as by welding, and the plates are secured to the web of the beam as by spot-welding the plates thereto at longitudinally spaced points.
Other modes of applying the principle of my invention may be employed instead of the ones explained, change being made as regards the constructions herein disclosed, provided the means stated by the following claim or the equivalents of such stated means be employed.
I therefore particularly point out and distinctly claim as my invention:
The method of strengthening a bridge, or the like, supported on I beams to which access may be had, which comprises welding an edge of a steel plate integral with one edge of a lower flange on a supporting beam, forcing a section of said plate into contact with the web of said beam and welding the opposite edge of said plate integral with the upper flange of said beam.
