Abstract

A chimney reinforcing device for increasing the resistance of a brick chimney to destruction during an earthquake. The chimney to be reinforced is of the type which extends above the roof line and which is built between two vertical studs within a wall. The chimney is reinforced by two shorter lengths of angle iron extending from near the top of the chimney to near the roof line and two longer lengths of angle iron which extend on the exterior corners of the chimney below the roof line. These four angle irons are tied together by one or more cables. The two longer lengths of angle iron are secured to the vertical studs providing a chimney top which is supported by the lower portion of the chimney and which is less likely to be destroyed in an earthquake.
