Abstract
This article proposes a prefabricated modular design in which springs and hinges have been used to assist the column’s passive installation (energy efficient In this technique, the roof panel and column were joined by a pivot hinge in the factory, enabling the pieces to be hoisted by the crane as a single unit for installation on the worksite. Also, there is a spring installed at a specified distance in the roof panel to assist in pushing the column and fastening it. This method helps to speed up the process of installing elements on the worksite, by reducing the number of times that the crane is used to lift elements throughout the installation process because instead of lifting one element each time, it lifts the two elements together at the same time. It is an efficient approach to reduce effort, time, and cost. In addition, the effect of the spring’s position in the panel on the amount of force required to push the column vertically was estimated in this study. The results demonstrate that the farther the spring distance from the pivot hinge, the less thrust force is required to elevate the column. Concerning the hinge that connects the roof panel to the column. The shear and crashing stresses that may be subjected to the hinge throughout the process of vertically installing the column were estimated to be within allowable limits.
