All components of the project are hoisted by the comprehensive hoisting method in the span, that is, the crawler crane is used to hoist the columns, beams, longitudinal supports and other components between the spans in order to form a stable system, and then hoist the next span.
Lighter materials / components can be handled on site manually.
4.5.2 selection of construction machinery four 30 ton crawler cranes are selected for the main power house.
Single machine rotation method is adopted for steel column hoisting.
Solar power stations, solar water heaters, electric vehicles and energy storage power stations are all based on mass production of batteries, and solar cell production is the demand side of purification projects.
The hoisting process is: steel column → support between columns → roof truss → roof support system (including skylight) → roof slab.
The steel structure shall be hoisted by comprehensive hoisting method, that is, after installing a row of transverse steel columns, the corresponding steel beams and support system shall be installed immediately to form a stable system.
Thank # Wenmeng for pursuing excellence, Zhai Lijuan Shared material.
The East and west wall panel systems shall be carried out after the installation of the main body of the steel structure, and the north and south wall panel systems shall be carried out after the structural capping of the office area and equipment room.

4.5 steel structure installation 4.5.1 installation principle according to the characteristics of the project, the installation principle is: first the main body, then the enclosure, first the lower part, then the upper part.
This device has applied for national patent.
Therefore, from today on, we will share the construction organization design of solar cell production projects.
4.5.3 the steel structure column can be installed after the bearing platform concrete is cured to 75% of a certain strength.
The steel beam and support system shall be installed alternately with the steel column, and the installation sequence is the same as that of the steel column.
We adopt the “new technology of roof slab high-altitude moving and pressing construction”, and use profiler, tower, winch, walking controller and other tools to assemble track walking high-altitude pressing plate device on the roof of the attached rooms on both sides of the plant.

The owner requires that the roof slab is a single slope, a whole slab, without overlapping and on-site processing.
