In accordance with the present invention, an elevator core structure includes an elevator frame () separated from a main frame () and extending in a longitudinal direction of the main frame (), and a guide frame () formed on an inner surface of the elevator frame (). Here, the elevator frame () may be formed by stacking a plurality of frame segments (), and a guide frame unit () forming the guide frame () may be mounted to one surface of each of the frame segments (). The present invention exhibits an effect of early-constructing the elevator frame regardless of a construction schedule of a main frame of a building.

A display apparatus includes a display assembly, and a mounting device on which the display assembly is supported. The mounting device may include a stand having a supporting boss, a rail disposed on a rear surface of the display assembly, and configured to move the display assembly in a straight line direction with respect to the supporting boss, and a rotation guide disposed at an end of the rail such that the display assembly rotates with respect to the supporting boss, wherein the display assembly is rotatable when the supporting boss is positioned on the rotation guide.

An RC lattice beam is provided that can greatly dampen the transfer of vibrations in particular. As the concrete included in the RC lattice beam is polymer concrete that contains a polymer, fine-scale vibrations that may otherwise affect exposure apparatuses may be effectively dampened, while the depth of the conventional lattice beam may be kept the same. Thus, a high-damping RC lattice beam is provided that is capable of maximizing the performance of a precision exposure apparatus by reducing the defect rate and improving productivity.
