Knowledge

1.1, technical preparation: the development of installation technology program, single-layer steel structure engineering should adopt the sub-installation method, roof system should adopt the comprehensive installation method.

1.2, construction equipment and material preparation: including hoisting machinery, all kinds of auxiliary construction equipment, steel components, all kinds of welding materials and fasteners.

1.3, column Base inspection: column base to find peace elevation control, review the Axis and play a good installation alignment line, check the foot bolt axis position, size and quality. 1.4, Component cleaning, cleaning steel column, such as the first hoisting member, number and bounce to install in place line. Install the front column bottom to remove rust cleaning.

2. Single-layer steel structure Engineering-steel column installation

Steel column Installation steel column should be used a bit of straight hanging and binding method to lift, in place when the foot bolts slowly fall, after the position screwed on the nut will be temporarily fixed, correct its flat and vertical degree, correct the final screw nut, with the pad and column bottom plate welding, and then the bottom of the column grouting fixed.

3. Single-layer steel structure engineering-Crane beam Installation

The crane girder adopts two points to tie, and when lifting, the air posture of the lifting process members is controlled by a slip rope, which facilitates the position and avoids collisions. After temporary fixation, the vertical degree, elevation and vertical and horizontal axis position of the crane beam should be corrected.

4. One-way steel structure Engineering-roof system Installation

The roof frame installation should be carried out after the column correction well is fixed; the house and the system can be expanded and assembled after hoisting, the expansion of the combined assembly Unit should become a spatial structure with a certain stiffness.

The installation of strip and other components shall be carried out after adjusting and locating the roof frame. Before the construction of steel structure engineering, we must have construction conditions to carry out construction, such as: The deepening design of the scheme, construction organization design documents, construction plans, the selection of formal construction units and so on.
