How to Place Grout Tubes Automatically in Precast Designs

Grout tubes are used in the construction of precast concrete buildings for connecting elements like walls, tilt-up panels, beams, and columns. They're also known as grout ducts or sleeves. The way it works is a starter bar (also known as a lap bar or dowel) is precast in one element, say, a wall panel, and then on site that dowel slides into

precast concrete Topic

Precast concrete is reinforced concrete constructed by industrialized methods. It is characterized by dividing the building into components, which are manufactured in a precast concrete plant, and transported by special transportation equipment to the site. Precasting reduces construction time because the manufacturing of the elements is carried out beforehand.
