Abstract
Abstract This invention relates to an improved concrete slab forming machine and further to a concrete slab forming machine having an improved sidemold member thereon operable to construct a concrete slab having unique sidewall construction with laterally extended wire mesh to provide for easy connection of adjoining pairs thereof. Still, more specifically, this invention relates to a sidemold structure having mesh guide bar means operable to produce concrete slabs having laterally extended mesh and providing new and novel means for adjoining adjacent concrete slabs through the use of the laterally extended mesh and other connecting means.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
115 words
A continuous spliced concrete joint to be formed through abutting concrete slabs having laterally extended reinforcing mesh therein, comprising: a. a pair of elongated abutting concrete slab members, each having a contour design sidewall in spaced relationship; b. said contour sidewall to form a substantially key-shaped design area between said abutting sidewalls of said concrete slabs; c. means for interconnecting said laterally extending mesh from said abutting concrete slabs; d. said key-shaped area filled with a grouting material; and e. said connecting means having elongated continuous mesh material interconnected to said laterally extended reinforcing mesh on said abutting concrete slab through wire-strip members, and said connecting means embedded in said key-shaped area when finally formed.
Claim 2
Dependent Claim
115 words
A continuous spliced concrete joint to be formed through abutting concrete slabs having laterally extended reinforcing mesh therein, comprising: a. a pair of elongated abutting concrete slab members, each having a contour design sidewall in spaced relationship; b. said contour sidewall to form a substantially key-shaped design area between said abutting sidewalls of said concrete slabs; c. means for interconnecting said laterally extending mesh from said abutting concrete slabs; d. said key-shaped area filled with a grouting material; and e. said connecting means having elongated continuous mesh material interconnected to said laterally extended reinforcing mesh on said abutting concrete slab through wire-strip members, and said connecting means embedded in said key-shaped area when finally formed.
Claim 3
Dependent Claim
111 words
A continuous spliced concrete joint comprising: a. a pair of elongated abutting concrete slab members, each having a contour design sidewall in spaced relationship to form a key-shaped area therebetween; b. means for interconnecting said laterally extending mesh from said abutting concrete slabs; c. said key-shaped area filled with a grouting material; d. said connecting means being a channel mesh joint structure e. said channel joint structure having a plurality of elongated parallel rod members interconnected in spaced relationship along its axis by hook members; and f. said channel mesh joint structure placed over said laterally extended reinforcing mesh of said concrete slabs whereupon said hook members are positively engaged therewith.
Claim 4
Dependent Claim
111 words
A continuous spliced concrete joint comprising: a. a pair of elongated abutting concrete slab members, each having a contour design sidewall in spaced relationship to form a key-shaped area therebetween; b. means for interconnecting said laterally extending mesh from said abutting concrete slabs; c. said key-shaped area filled with a grouting material; d. said connecting means being a channel mesh joint structure e. said channel joint structure having a plurality of elongated parallel rod members interconnected in spaced relationship along its axis by hook members; and f. said channel mesh joint structure placed over said laterally extended reinforcing mesh of said concrete slabs whereupon said hook members are positively engaged therewith.
Claim 5
Dependent Claim
56 words
A continuous spliced concrete joint as described in claim 2, wherein: a. said hook members of a generally U-shape having a main body portion and integral leg portion at opposite ends thereof; and b. said leg portions engage said reinforcing mesh from said concrete slabs in a clamping relationship to provide a neat appearing, rigid structure.
