What are the dangers of the position and vertical deviation of the foundation bolts of the steel structure building?
The position and verticality of the pre-embedded or reserved holes of the foundation bolts of the steel structure building exceeds the allowable deviation value of the specification. The reasons are: the pre-buried anchor bolts (or the pre-buried holes with the plug body are the same) without the use of a fixing frame Fixing, or the rigidity and strength of the fixed frame set are not enough, the concrete pouring is subject to vibration and collision, which causes the displacement and inclination of the anchor bolts; or there is an error in the axis of the foundation construction, or the measurement size is wrong, or the use of a steel ruler has not been verified There is an error; or after the burial is not carefully checked, resulting in a large deviation in position and verticality; or there are errors or errors in design drawings, measurements, operations, etc.; due to the excessive position and verticality of the bolts, it will make the installation of the steel column difficult or installation. Failure to do so, or generating excessive normal stress, will affect the reliable and normal use of the column on the foundation.
