Instaling Project XSTING3/11/2024 ![]() ![]() Therefore, all machines and equipment employed precast concrete element handling and erection need to be maintained to a high standard, load tested, and be suited to the intended utilization. Safety during the handling and erection of precast concrete elements is substantially important. Finally, a trial erection operation should be considered to identify any unforeseen erection difficulties. The erection sequence shall avoid multiple handling of elements. The erection plan is commonly prepared drawings If it is important for structural stability and for access to connections at specific location. ![]() ![]() Precast concrete members shall be erected according to preplanned sequence. 9: Precast Concrete Stairs Precast Concrete Construction Considerations 1. Erection Sequence There are three arrangements of large panel system based on wall layouts which include cross-wall system, longitudinal-wall system, two-way system.įig. It consists of large walls and floor concrete panels connected in the vertical and horizontal directions.īoth horizontal and vertical panels withstand gravity loads. Large panel systems are useful for the construction of apartments and hotels. There are four major types of precast systems which are classified based on the on the load bearing structure: In order to understand the construction of precast concrete structure, different precast systems shall be known. In this manner, the imposed loads are transferred from superstructure to the foundation.ĭesigners should consider the possibilities, restrictions, detailing, manufacturer, transport, erection and serviceability stages before finalizing the design of precast concrete structure. Various connections have been developed to connect different types of structural elements like beam to column connection and panel to panel connection. After that, they are delivered to the project site to be erected. In precast concrete construction, majority of structural members are manufactured in manufacturing plants away from the construction site. □ Reading time: 1 minutePrecast concrete construction system has its own characteristics which influence the layout, span length, construction depth, and stability system to a great extent. ![]()
