Abstract
Abstract A construction for a retaining wall member utilizes a preformed channel in the member communicating through a slit formed between the channel and one face of the member for retention of a tieback utilized to affix the member to an underlying mass. The tieback may be retained by the mechanical interference between the walls of the slit and an enlarged portion of the tieback located within the channel. Alternatively, an interference rod may be inserted into the channel to retain the tieback.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
144 words
In a retaining wall construction utilizing a plurality of panels as retainers for an underlying mass with each panel secured to said mass by anchors embedded in said mass, the improvement comprising: (a) a plurality of channels formed in said panels with each channel communicating with the side of said panel adjacent said underlying mass via a slit extending along said channel; and (b) means for securing one end of said anchor within said channel to prevent withdrawal of said anchor through said slit with said slit having a transverse width slightly greater than the thickness of said anchor proximal said one end with said one end having an increased terminal thickness and smaller than the transverse width of said channel and said means for securing comprising an interference rod inserted within said channel such that the effective width of said slit is reduced.
Claim 2
Dependent Claim
144 words
In a retaining wall construction utilizing a plurality of panels as retainers for an underlying mass with each panel secured to said mass by anchors embedded in said mass, the improvement comprising: (a) a plurality of channels formed in said panels with each channel communicating with the side of said panel adjacent said underlying mass via a slit extending along said channel; and (b) means for securing one end of said anchor within said channel to prevent withdrawal of said anchor through said slit with said slit having a transverse width slightly greater than the thickness of said anchor proximal said one end with said one end having an increased terminal thickness and smaller than the transverse width of said channel and said means for securing comprising an interference rod inserted within said channel such that the effective width of said slit is reduced.
Claim 3
Dependent Claim
27 words
The improvement as defined in claim 1 wherein said channel has interior walls adjacent said slit cooperatively formed to retain said one end adjacent said interference rod.
Claim 4
Dependent Claim
29 words
The improvement defined in claim 2 wherein said anchor comprises a generally planar mesh wherein said one end has an enlarged portion formed thereon for insertion into said channel.
Claim 5
Dependent Claim
33 words
The improvement defined in claim 2 further comprising sealing means for insertion within said channel about said one end and said retaining rod for adhering said anchor and said rod with said channel.
Claim 6
Dependent Claim
25 words
The improvement defined in claim 1 wherein said channel has interior walls adjacent said slit cooperatively formed to retain said enlarged portion within said channel.
Claim 7
Dependent Claim
27 words
The improvement defined in claim 5 further comprising sealing means for insertion within said channel about said one end for adhering said one end within said channel.
Claim 8
Dependent Claim
97 words
Apparatus for use in a retaining wall construction wherein said retaining wall supports an underlying mass comprising: (a) a panel member having a plurality of elongated channels formed therein, each channel communicating with one side of said panel member through an elongated slit; (b) tieback means for anchoring said panel member to said underlying mass, said tieback means having an enlarged portion insertable into said channel through said slit; and (c) means for retaining said tieback means within said channels comprising an interference rod insertable longitudinally within said channel for reducing the effective width of said slit.
Claim 9
Dependent Claim
97 words
Apparatus for use in a retaining wall construction wherein said retaining wall supports an underlying mass comprising: (a) a panel member having a plurality of elongated channels formed therein, each channel communicating with one side of said panel member through an elongated slit; (b) tieback means for anchoring said panel member to said underlying mass, said tieback means having an enlarged portion insertable into said channel through said slit; and (c) means for retaining said tieback means within said channels comprising an interference rod insertable longitudinally within said channel for reducing the effective width of said slit.
Claim 10
Dependent Claim
22 words
Apparatus as defined in claim 7 further comprising means for cementitiously binding said interference rod and said enlarged portion within said channel.
Claim 11
Dependent Claim
27 words
The improvement as defined in claim 7 wherein said channel has interior walls adjacent said slit cooperatively formed to retain said one end adjacent said interference rod.
