Construction member

A construction member for facilitating movement of structural components along a given reference plane, comprising:

• a first portion having a main body which has opposite first and second ends, and further has opposite first and second surfaces, and wherein the main body has a first course, a second course joined to the first course, and which is substantially perpendicular to the first course, a third course, which is joined to the second course, and which is substantially perpendicular to the second course, and which is disposed in substantially parallel spaced relation relative to the first course, a fourth course, joined to the third course, and which is disposed in substantially perpendicular relation relative to the third course and which further is disposed in substantially parallel, spaced relation relative to the second course, a fifth course, joined to the fourth course and which is substantially perpendicular to the fourth course, and which further is disposed in substantially parallel, spaced relation relative to the third course, a sixth course joined to the fifth course and which is disposed in substantially perpendicular relation relative to the fifth course, and which is further disposed in substantially parallel spaced relation relative to the fourth course, and which further is disposed in a substantially coplanar orientation relative to the third course, and a seventh course, joined to the sixth course, and which is disposed in substantially perpendicular relation relative to the sixth course, and which is further disposed in substantially parallel spaced relation relative to the first, third, and fifth courses, and wherein a first channel is defined, at least in part, between the first and seventh courses, and which extends between the first and second ends of the main body, and wherein the first channel has a first width dimension, and wherein the first channel matingly receives a first structural component therein, and which is fastened to at least one of the first or seventh courses, and wherein the third, fourth and fifth courses define a second channel which extends substantially between the first and second ends of the main body and which further has a second width dimension which is less than about 80% of the first width dimension;
• and
• a second portion mounted on a second structural component and which has a first course, a second course joined to the first course, and which is substantially perpendicular to the first course, and wherein the second course is juxtaposed relative to the second structural component, and a third course joined to the second course, and which is disposed in substantially perpendicular relation relative to the second course, and which is further disposed in substantially parallel, spaced relation relative to the first course, and wherein the second portion has a width dimension as measured between the first and third courses thereof, and which is less than about the width dimension of the second channel, and wherein the second portion is moveably received, at least in part, in the second channel and facilitates substantially coplanar movement of the first and second structural components, one relative to the other.
