Patent number: 6848232Abstract: A casting tool for forming precast concrete wall sections. A base is disposed generally in a horizontal plane and has an upper surface. A pair of opposing sidewalls are disposed proximate the upper surface. Each of the sidewalls has a first position in which the sidewall is located substantially in a vertical plane. First and second opposing bulkheads are disposed proximate the upper surface, each having a respective first position in which the bulkhead is located substantially in a vertical plane. The bulkheads are arranged to abut the pair of opposing sidewalls so that the inner surfaces of the sidewalls, the bulkheads, and the upper surface of the base define a form for receiving concrete to make the precast concrete wall section. The first bulkhead is configured for movement so as to vary a first dimension of the form, and thus the dimension of the concrete wall section.Type: GrantFiled: March 6, 2003Date of Patent: February 1, 2005Assignee: PN II, Inc.Inventors: William J. Pulte, Lawrence J. Wrass, Robert P. Broad

Publication number: 20040068948Abstract: A party wall system for installation between adjacent units of a multi-unit residential dwelling comprises at least one party wall panel having a foam core, at least one structural stud partially embedded in a first face of the core and at least one structural stud partially embedded in a second face of the core, and a concrete member covering the second face of the core. A fire-resistant sheet is affixed to the structural stud in the first face of the core. The fire-resistant sheet is spaced from the first face and defines a first sound channel therebetween. A spacer is affixed to the structural stud in the second face of the core and exterior of the concrete member. A fire-resistant sheet is affixed to the spacer, and the fire-resistant sheet is thereby spaced from the concrete member and defines a sound channel therebetween.Type: ApplicationFiled: October 2, 2003Publication date: April 15, 2004Inventor: Lawrence J. Wrass
