Description
Steel construction lower margin consolidates mounting structure Technical Field The utility model relates to the technical field of construction components of building steel structures, in particular to a steel structure foundation strengthening and installing structure. Background Before the steel structure column is assembled with the cement base, steel structure foundation feet are needed to be embedded in the cement base, and bolts assembled with the steel structure column are arranged at the upper ends of the steel structure foundation feet. According to publication number CN203174622U and publication number 2013-09-04, a pre-buried installation fixing device for steel structure column foundation bolts is disclosed, which comprises steel structure foundation bolts provided with bolts and a horizontal locating plate in installation connection with the bolts. In the prior art including above-mentioned patent, because steel construction lower margin need use upper and lower nut to fasten in locating plate both ends face when carrying out the assembly with horizontal locating plate, consequently, the nut only can exist in the bolt position for the screw thread that surface processing formed must bear torsion and stress, if steel construction lower margin exposes certain length in actual construction process, and when not seting up the position of screw thread equal to or surpass and bear normal torsion and stress scope, screw thread position very easily receives the compression deformation, and under external corrosion action, accelerate the wearing and tearing of deformation position, set up and cause partial screw thread fracture on steel construction lower margin, cause steel construction post base security to reduce.
