In order to the safety of construction personnel, the state of the steel structure summed up many years of experience in the integration of a set of standard steel structure installation steps, I hope the construction personnel in strict accordance with the steps of the implementation of construction: Check the pre buried bolt specifications, size, location, elevation of the length of exposed, the review confirmed that the age of concrete embedded parts. Check the drawings, check the consistency of the field components and the design, to prevent the wrong installation.
To investigate the site of operation, to determine the walking route of the crane and to formulate the lifting scheme. Installation of high-strength bolts, bolts should be free to penetrate the hole, can not be arbitrarily enlarged, high-strength bolts can not replace the use of temporary bolts. 16T wheel crane is used as hoisting machinery. The steel column is lifted by one or two points, and is temporarily fixed after being in place. The steel beam shall be lifted by two points, the lifting point should be determined in advance, and the test crane should be tested in order to guarantee the stability. After the erection of the steel beam is temporarily fixed, after the installation of the horizontal support, after checking the verticality of the final fixed. The whole frame is installed, should make an inspection of the framework has been installed, confirm the validity of all components of the installation of the connecting piece are fastened, the overall bending is within the standard deviation. After the steel frame has been checked and correct, it shall be completed by the civil construction unit in time to pour the concrete of the column floor. The construction of steel parts can also be implemented.
