Abstract
Abstract A device for forming a continuous reinforced concrete wall in which the reinforcement overlaps between adjacent sections of the wall to provide continuity of sheer strength in the wall. The method utilizes a mould end of the invention, which is shaped to protect projecting ends of reinforcement bars during casting of a concrete panel forming the wall. The next cast panel is then cast around the projecting free ends of the reinforcement bars of the previous panel.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
178 words
A mould end device for forming a continuous wall from reinforced concrete panels cast in successive portions in a trench dug in the ground, each concrete panel comprising reinforcement basket means having at its both ends lateral extensions protected from concrete during concrete casting of said panel; wherein said device comprises substantially vertical columns having a substantially four-sided form in cross section, two opposite parallel lateral faces of which are adapted to be located adjacent to the longitudinal walls of the trench, the other faces of said columns being respectively a casting face for said concrete panel and an opposite face having in cross section a semi-circular concave shape to constitute a guide for a grab of an excavator for extending said trench, said casting face being provided with a central trapezoidal recess extending longitudinally along said casting face and with two parallel longitudinally extending slots located in planes parallel to said lateral faces and on each side of said central recess near said parallel opposite faces for receiving and shielding said lateral extensions of said basket means.
Claim 2
Dependent Claim
178 words
A mould end device for forming a continuous wall from reinforced concrete panels cast in successive portions in a trench dug in the ground, each concrete panel comprising reinforcement basket means having at its both ends lateral extensions protected from concrete during concrete casting of said panel; wherein said device comprises substantially vertical columns having a substantially four-sided form in cross section, two opposite parallel lateral faces of which are adapted to be located adjacent to the longitudinal walls of the trench, the other faces of said columns being respectively a casting face for said concrete panel and an opposite face having in cross section a semi-circular concave shape to constitute a guide for a grab of an excavator for extending said trench, said casting face being provided with a central trapezoidal recess extending longitudinally along said casting face and with two parallel longitudinally extending slots located in planes parallel to said lateral faces and on each side of said central recess near said parallel opposite faces for receiving and shielding said lateral extensions of said basket means.
Claim 3
Dependent Claim
160 words
A mould end device for use in the forming of a continuous wall from reinforced concrete panels cast in successive portions in a trench dug in the ground, said concrete panels being of the type having reinforced basket means with extensions adapted to project laterally from the panels; said mould device comprising a four-sided vertical column having a pair of parallel opposite lateral faces adapted to be positioned adjacent the longitudinal walls of the Trench, a casting face joining the lateral faces on first edges thereof, and an opposite face joining the lateral faces on the opposite edges thereof, said casting face having a central longitudinally extending recess, said opposite face having a longitudinally extending excavator guide slot, said column further having first and second parallel longitudinally extending slots in said casting face on opposite sides of said central recess in planes parallel to said lateral faces and adjacent said lateral faces for receiving said extensions of said basket means.
Claim 4
Dependent Claim
160 words
A mould end device for use in the forming of a continuous wall from reinforced concrete panels cast in successive portions in a trench dug in the ground, said concrete panels being of the type having reinforced basket means with extensions adapted to project laterally from the panels; said mould device comprising a four-sided vertical column having a pair of parallel opposite lateral faces adapted to be positioned adjacent the longitudinal walls of the Trench, a casting face joining the lateral faces on first edges thereof, and an opposite face joining the lateral faces on the opposite edges thereof, said casting face having a central longitudinally extending recess, said opposite face having a longitudinally extending excavator guide slot, said column further having first and second parallel longitudinally extending slots in said casting face on opposite sides of said central recess in planes parallel to said lateral faces and adjacent said lateral faces for receiving said extensions of said basket means.
