Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 202 words
A concrete formwork soldier for use with concrete formwork, said soldier comprising two elongated members positioned parallel one to the other, each of said members having a generally U-shaped cross-sectional configuration, said members being positioned in back-to-back relation with side flanges of said members extending away one from another, and said members being positioned to establish a space between backs of said members, and a plurality of connecting members positioned between the backs of said elongated members within said space, each connecting member being connected to the backs of both of said elongated members for restraining said members in spaced, back-to-back relation, said connecting members themselves being located in spaced relation one from the other from one end of said elongated members to the other, opposite ends of said connecting members cooperating with the backs of said elongated members to define two separate channels extending the length of said soldier from one end to the other end for use in connecting said soldier to concrete formwork, said channels being located opposite one another and separated by said connecting members, each of said channels being located inwardly of the side flanges of said members within said space established between backs of said members.
Claim 2
Dependent Claim 202 words
A concrete formwork soldier for use with concrete formwork, said soldier comprising two elongated members positioned parallel one to the other, each of said members having a generally U-shaped cross-sectional configuration, said members being positioned in back-to-back relation with side flanges of said members extending away one from another, and said members being positioned to establish a space between backs of said members, and a plurality of connecting members positioned between the backs of said elongated members within said space, each connecting member being connected to the backs of both of said elongated members for restraining said members in spaced, back-to-back relation, said connecting members themselves being located in spaced relation one from the other from one end of said elongated members to the other, opposite ends of said connecting members cooperating with the backs of said elongated members to define two separate channels extending the length of said soldier from one end to the other end for use in connecting said soldier to concrete formwork, said channels being located opposite one another and separated by said connecting members, each of said channels being located inwardly of the side flanges of said members within said space established between backs of said members.
Claim 3
Dependent Claim 20 words
A soldier as set forth in claim 1, said soldier comprising a reinforcement member secured in one of said channels.
Claim 4
Dependent Claim 26 words
A soldier as set forth in claim 1, said soldier comprising a stiffener plate fixed between opposite flanges of at least one of said elongated members.
Claim 5
Dependent Claim 64 words
A soldier as set forth in claim 1, said soldier comprising at least one hole defined in the back of each elongated member, each hole in one elongated member being generally aligned with a hole in the other elongated member, said hole pair in each soldier being adapted to receive a waling therethrough for restraining at least two of said soldiers in connected relation.
Claim 6
Dependent Claim 248 words
Concrete formwork comprising a plurality of soldiers, each of said soldiers comprising two elongated members positioned parallel one to the other, each of said members having a generally U-shaped cross-sectional configuration, said members being positioned in back-to-back relation with side flanges of said members extending away one from another, and said members being positioned to establish a space between backs of said members, and a plurality of connecting members positioned between the backs of said elongated members within said space, each connecting member being connected to the backs of both of said elongated members for restraining said members in spaced, back-to-back relation, said connecting members themselves being located in spaced relation one from the other from one end of said elongated members to the other, opposite ends of said connecting members cooperating with the backs of said elongated members to define two separate channels extending the length of said soldier from one end to the other end for use in connecting said soldier to concrete formwork, said channels being located opposite one another and separated by said connecting members, each of said channels being located inwardly of the side flanges of said members within said space established between backs of said members, and a concrete formwork panel extending across the side flanges of said soldiers on at least one side thereof, said panel being connected with each of said soldiers by connector structure received in one of said channels defined by said elongated members and said connecting members.
Claim 7
Dependent Claim 248 words
Concrete formwork comprising a plurality of soldiers, each of said soldiers comprising two elongated members positioned parallel one to the other, each of said members having a generally U-shaped cross-sectional configuration, said members being positioned in back-to-back relation with side flanges of said members extending away one from another, and said members being positioned to establish a space between backs of said members, and a plurality of connecting members positioned between the backs of said elongated members within said space, each connecting member being connected to the backs of both of said elongated members for restraining said members in spaced, back-to-back relation, said connecting members themselves being located in spaced relation one from the other from one end of said elongated members to the other, opposite ends of said connecting members cooperating with the backs of said elongated members to define two separate channels extending the length of said soldier from one end to the other end for use in connecting said soldier to concrete formwork, said channels being located opposite one another and separated by said connecting members, each of said channels being located inwardly of the side flanges of said members within said space established between backs of said members, and a concrete formwork panel extending across the side flanges of said soldiers on at least one side thereof, said panel being connected with each of said soldiers by connector structure received in one of said channels defined by said elongated members and said connecting members.
Claim 8
Dependent Claim 58 words
Concrete formwork as set forth in claim 5, at least one hole defined in the back of each elongated member, each hole in one elongated member being generally aligned with a hole in the other elongated member, and including a waling through said hole pair in each soldier restraining at least two of said soldiers in connected relation.
