UNITED STATES Patented September 27, 1904 WILLIAM L. CHURCH, OF BOSTON, MASSACHUSETTS.
RETAININGr'WALLl SPECIFICATION forming part of Letters Patent No. 770,844, dated September 27, 1904.
Application led July 29, 1904. Serial No. 218,732. (No model.)
To all whom t may concern.-
Be it known that I, WILLIAM L. CHURCH, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements inl Retaining-Walls, of which the following is a specification.
This invention relates to retaining-walls, damsLand like structures having a concrete or cement body reinforced with steel. In a patent, No. 7 64,916, issued to me July 12, 1904, is described a structure of this character in which an upright wall and floor are connected by straight metallic tension members.
The present invention has for its object to provide greater strength for the wall or dam by improved disposition of the tension members with relation to the body of the structure, giving something in the nature of a truss construction.
Of the accompanying drawings, Figure 1 represents a vertical section through the upright and bottom walls and one of the buttresses of a retaining-wall or similar structure constructed according to my invention. Fig. 2 represents a plan view of said structure.
The same reference charactersindicate the same parts in both figures.
In the drawings, 10 11 represent, respectively, the upright wall and the bottom wall or floor of the structure, the said walls composed of concrete and integrally united, and 12 12 a series of upright buttresses of the same material connecting these walls. The walls are or may be formed opposite the edges of the buttresses with ribs or flanges 13 of the same material for a purpose to be described.
14 14 are tension rods or bars of any of the well-known types rendered self-locking in connection with the concrete by suitable projections, these members being embedded in the upright Wall 10 and the buttresses 12. A similar series of bars 15 is embedded in the bottom wall 11 and the buttresses 12, the two series in each buttress meeting atan angle and the rear outline of the buttress being salient to accommodate this angle. It will be noted that the three outer members of the set of rods 14 have their rear ends embedded independently of the top ends of the three outer bars of the set 15, while the inner members 14 15 of each set are parts of the same bar bent at an angle. The independently-embedded bars afford a somewhat cheaper construction, and their connection 'with each other through the concrete is ample for the purposes desired. That portion of each buttress 12 extending from the apices of the bars 14 15 to the angle between the upright and bottom walls 10 11 may be considered as forming a compression-strut after the manner of certain well-known forms of truss, an imaginary strut of this character being outlined in darker shading at 16.
The ribs or flanges 13 are considered as portions or extensions of the walls 10 11 and serve to embed the ends of the rods 14 15 such a distance in the concrete of said walls as will make the rods substantially unwithdrawable without breakage thereof. This distance for material of the strength of Bessemer steel amounts to about thirty times the diameter of the rod.
It will be understood from the foregoing that the above dispositionl of parts affords increased strength over a construction employing straight tension members and over various other structures lacking the truss principle above set forth.
I claimm- 1. A retaining Wall or similar structure comprising integral concrete upright and bottom walls, angularly-related metallic tension members embedded in said walls, and a compression-strut interposed between the wall structure and the apex of said tension members.
2. A retaining wall or similar structure comprising integral concrete upright and bottom Walls, concrete buttresses connecting said walls, and angularly-related self -locking metallic tension-rods embedded'in said walls and buttresses and includingv the substance of said buttresses as compression-struts between their apices and the angle between the said walls.
In testimony whereof I have aiiixed my signature in presence of two witnesses.
