Preparation Work
The selection of lifting equipment is based on the characteristics of Multistory Steel Structures, plane layout, weight of steel components, installation difficulty, etc. Tower cranes are mainly used, and the underground part is completed with crawler or truck cranes.

 

Laying Out The Lines
The measurement and laying out work during the installation stage of Multistory Steel Structures includes the establishment of a control network, vertical delivery of plane axis control points, plane laying out of column tops, transmission of elevations by suspended steel rulers, coordinate measurement of complex plane steel structures, and deformation monitoring of steel structure installation. The measurement plan is compiled and strictly implemented after review and approval.

 

Line Inspection
Before the installation of the Multistory Steel Structure, the foundation of the civil engineering part has been completed. In order to ensure the quality of the Multistory Steel Structure installation, the civil engineering construction party is first required to provide the building axis, elevation, axis reference point, and elevation reference point after entering the site, and then re-measure the axis and elevation. The axis re-measurement method should be different according to the plane shape of the building, and it is advisable to use a total station. The axis and elevation of the column base must be consistent with the construction drawings, and the bolt pre-embedded should be accurate. The elevation deviation is controlled within +5mm, and the deviation of the positioning axis is controlled within ±2mm. It should be jointly accepted by the design, supervision and general contractor.

 

Installation Of Column And Beam Core Frame
The hoisting of Multistory Steel Structures is divided into operation areas according to the plan layout, and multiple hoisting methods are used in sequence. Generally, it starts from the middle or a certain symmetrical interval, with the column grid of one interval as the hoisting unit, and hoists in the order of steel columns, steel beams, and supports, and expands to the surroundings. After forming a stable structure from bottom to top in the vertical direction, the secondary structure is installed in layers. After the first interval is completed, measurement, correction, and initial tightening of high-strength bolts are carried out. Then, the steel components of several intervals around are installed, and then measurement and correction, final tightening of high-strength bolts, and welding are carried out. A symmetrical fixing process is used to reduce the accumulation of installation errors and node welding deformation.

 

Steel Column Installation
The column length should be determined according to factors such as factory processing, transportation and stacking, and on-site hoisting. It is advisable to take 2 to 4 floor heights, and the segment position should be 1.0 to 1.3m above the beam top elevation. 1) As the rigidity of the steel column is good, the lifting point adopts a single-point straight lifting. The lifting point is installed at the top of the column, the column body is vertical, and the lifting point passes through the center of gravity of the column, which is easy to lift, position and correct. 2) Generally, a single crane is used for lifting. For special or overweight components, double cranes can also be used for lifting. However, it should be noted that the same type of cranes should be used as much as possible. The load of each crane should not exceed 75% of the rated lifting capacity. When lifting, they should cooperate with each other. If an iron pole is used for lifting, the iron pole should be kept balanced to avoid a safety accident caused by the weightlessness of one machine and the overload of the other machine. 3) When lifting, the steel column should be kept vertical and the root of the column should not be dragged. When rotating in place, prevent collision with other frames, and the sling should have a certain effective height. 4) Before installing the steel column, the hanging basket and climbing ladder should be fixed at the predetermined position of the steel column. After being in place, temporarily fix the anchor bolts and correct the verticality. Connecting plates for temporary fixation are installed on both sides of the steel column. After the upper section of the steel column is aligned with the center line of the top of the lower section of the steel column, the connecting plates are fixed with bolts for temporary fixation. 5) The steel column is installed in place and aligned with the axis. The sling can only be loosened after the anchor bolts are fixed.

 

High-Strength Bolt Connection And Fixing
High-strength bolts should be inserted into the hole freely, and should not be knocked forcibly. The insertion direction should be consistent and easy to operate; washers should be installed on one side of the nut, and the chamfered side of the washer should be in contact with the bolt, and should not be installed upside down. When high-strength bolts cannot be inserted freely, gas cutting should not be used to expand the hole, and a reamer should be used to repair the hole. The maximum diameter after repairing the hole should not be greater than 1.2 times the bolt diameter, and the number of repaired holes should not exceed 25% of the number of bolts at the node. Before repairing the hole, all the bolts around should be tightened, and the plate should be tightly attached before reaming. High-strength bolts should not be installed in rainy or snowy weather, and the friction surface should be in a dry state.

 

High-Strength Bolt Tightening
High-strength bolt tightening should be carried out twice, namely, initial tightening and final tightening. Large nodes should also be re-tightened, and re-tightening should be carried out after the plates are tightly stacked.

 

Beam And Column Node Welding
The quality of the installation weld should meet the design requirements. When the installation positioning weld is subjected to load, the number, height and length of the weld points shall be determined by calculation; when it is not subjected to load, the spot welding length shall not be less than 10% of the designed weld length and shall not be less than 50mm.

 

Installation Of Sporadic Components (Corner Braces)
Sporadic components shall be installed after the column and beam frame form a stable structure and the beam and column nodes are tightened and welded and accepted.
