Chapter VIII Construction Scheme and Technical Measures

I. General situation of construction

Second, the earthwork

The steel bars are processed and shaped at the site according to the drawing design requirements, and then hoisted to the construction area by tower crane. Before steel binding, you should be familiar with the drawings and check whether the grade, diameter, shape, size and quantity of semi-finished steel bars are consistent with the material card. If there are any mistakes and omissions, they should be corrected and supplemented. Draw the positioning line of steel bar installation, and indicate the specification, shape, size and quantity of steel bar at the binding part, and brush the concrete surface at the position of construction joint with steel wire brush.

Flash butt welding or one-sided lap welding is proposed. The remaining steel bars with a diameter less than 18mm are to be bound and lapped.

Fourth, the template project

The first floor of the teaching building in this project is 4.2m high, and the height above the second floor is 3.6m.. Due to the high height of the first floor and dense steel bars, the construction is difficult, so we must pay enough attention to it during construction. Its formwork support scheme is not only the difficulty of formwork engineering, but also the difficulty of this project. We must determine the formwork support scheme through detailed calculation and report it to relevant departments for approval.
