1.Site requirements for steel structure hoisting　　

Generally speaking, the construction site of the project should meet such a condition as three supplies and one leveling, which means that the power should be supplied separately first, in order to prevent the possibility of sudden power failure, which will bring certain losses to the enterprise, so the construction site should have independent power distribution settings.Secondly, the transportation should be convenient, which must be done, because the construction materials or machinery transported by the enterprise are very large. If the transportation cannot be delivered in time, the construction project will be delayed, which will also bring certain losses to the enterprise.Finally, the construction site should be relatively flat, most of which are easy to achieve, mainly for the purpose of making the operation of mechanical equipment more convenient and easy to operate.

2.Hoisting technology of steel members

2.1 Hoisting construction sequence

Generally speaking, the lifting construction sequence starts from the ground, and then the underground work.According to the sequence of first main structure and then secondary components, this sequence shall not be disordered, otherwise it may affect the smooth construction.

2.2 Installation management of embedded parts of steel members

What is most closely related to the quality of project management is the safety situation of steel member hoisting construction and the installation management of embedded parts. Because of this, generally in the installation process of embedded parts, accuracy control will be carried out according to the construction specifications of steel members first, or the embedded parts will be corrected according to the regulations on the drawing paper.

2.3 Hoisting construction of steel columns and beams with steel members

The construction of steel members should be carried out according to its process and site.Then, according to the process requirements and the actual situation of the site, the steel column and steel beam of steel members should be hoisted in order, and the good cooperation between labor and machinery should be fully coordinated. The most important part in the construction of steel member hoisting is the inspection, which is the inspection after the steel member hoisting, which is the key step to ensure the quality.There are certain requirements for engineering construction in our country, such as whether the construction process complies with relevant regulations, laws and regulations, or relevant regulations and requirements, etc., as well as provisions for the corresponding flatness of steel columns or steel beams of components, which are designed to ensure the quality and ensure the quality of the building.
