Abstract
The present invention is a precast concrete sandwich panel utilizing a low density polyethylene channel with basalt fiber rod attached to the side of the channel during construction, and utilizing spray foam insulation as the inner layer between the two concrete outer panels (wythes).
Claims8
A precast concrete sandwich panel, comprising in combination:
- a lower wythe with reinforcement material embedded therein;
- an upper wythe with reinforcement material embedded therein;
- an insulating layer formed between the lower wythe and the upper wythe;
- at least one channel oriented during construction of the panel having a base wall and a pair of opposed side walls;
- and
- a pair of rods permanently affixed to an outer surface of the opposed side walls of the channel, the rods being of a sine-wave shaped pattern defined by peaks spaced at a regular interval and with peak-to-peak amplitude greater than the insulating layer and mechanically joined with the lower wythe and the upper wythe.
