Tilt-up and precast construction panels

A method of using a tilt-up or precast construction panel kit to form a tilt-up or precast construction panel core body adapted to be set in concrete in a tilt-up or precast construction panel form and have concrete poured over the core body thereafter to form a tilt-up or precast construction panel, the method comprising:

• obtaining a tilt-up or precast construction panel kit, the kit comprising:
• a plurality of core body segments, each core body segment comprising:
• a welded grid body comprising:
• two parallel plane grid mats of longitudinal and transverse wires crossing one another and welded together at the points of cross, the plane grid mats spaced apart from each other by a gap;
• and
• straight spacer wires cut to length and welded at each end to one wire of a respective one of the grid mats;
• a slab of heat-insulating material disposed within the gap between the parallel plane grid mats with a space between the slab of heat-insulating material and each of the two parallel plane grid mats;
• and
• two end cap grid mats each comprising a first plane grid mat of longitudinal and transverse wires, the first plane grid mat being formed into a U shape and affixed to the two parallel plane grid mats so as to encompass one of two opposite transverse ends of the slab of heat-insulating material within grid mat wires;
• wherein two end core body segments of the plurality of core body segments each comprises a side cap grid mat comprising a second plane grid mat of longitudinal and transverse wires, the second plane grid mat being formed into a U shape and affixed to the two parallel plane grid mats so as to encompass one longitudinal end of the slab of heat-insulating material within grid mat wires;
• placing the first end core body segment on an underlying surface with the one or more plane splice mats lying on the underlying surface;
• repeating steps of:
• securing an additional core body segment adjacent a previous core body segments on the underlying surface;
• and
• securing the additional core body segment to the previous core body segment;
• when only a second end core body segment remains, placing the second end core body segment immediately adjacent the previous core body segment on the underlying surface such that a longitudinal edge opposite the side cap grid mat of the second end core body segment is immediately adjacent the previous core body segment;
• and
• securing the second end core body segment to the previous core body segment, whereby the core body segments are secured into a unitary construct.
