Patent ID: 8132979

Claim:
An assembly for use in construction, said assembly comprising: a first engaging member defining a geometric shape and at least one internal channel, said first engaging member having an internal surface and an external surface; a second engaging member defining a geometric shape and at least one internal channel, said second engaging member having an internal surface and an external surface; a first coupling member for connecting said first and second engaging members, said coupling member having an internal surface and an external surface and defining at least one internal channel; and a first elongate member defining an internal cavity and a cross section, said first elongate member having an internal surface, a first end, and a second end, wherein at least one end of said first elongate member is open for receiving said first engaging member; a second elongate member defining an internal cavity and a cross-section, said second elongate member having an internal surface, a first end, and a second end, wherein at least one end of said second elongate member is open for receiving said second engaging member; and one or more controllers in communication with said first elongate member and said second elongate member, wherein the one or more controllers regulate an environment within each of said internal cavities of said first and second elongate members, the one or more controllers being a variety of controlling mechanisms to control the flow of various components through the assembly; wherein said first engaging member is secured to said second engaging member by said first coupling member extending through each of said channels of said first and second engaging members; wherein the assembly is in communication with a manifold assembly.
