Description

Technical Field

[0002] In the field of prefabricated steel structure housing, the design structure approach of "one steel column supporting and connecting four floors of floor decking" is generally adopted. The position deviation and verticality requirements of the steel column installation of the steel structure are very strict. Due to the long length of the steel column itself, once the verticality deviation of the steel column occurs, it will affect the construction of the floor decking of the upper layers, and it will be very difficult to correct the verticality again.

[0003] At present, the connection and installation of steel columns in prefabricated steel structure houses are generally carried out by welding connecting ear plates on the steel columns. After the steel columns are transported to the site, the two sections of the steel columns are hoisted and aligned, and the connecting ear plates of the upper and lower sections of the steel columns are connected by connecting plates to temporarily fix and install the two sections of the steel columns. After the steel columns are connected and installed, the verticality of the steel columns is measured and checked. For steel columns with excessive deviations, steel wire ropes and hand hoists are generally used to pull the top of the steel columns in opposite directions to adjust the verticality. This method cannot accurately control the verticality of the steel columns. The top of the steel columns are easily deformed by lateral tension, which cannot guarantee the structural safety and verticality of the steel columns. Summary of the invention

The jack 4 drives the adjustment top plate to symmetrically return the adjustable ear plate to the top, so as to achieve the purpose of accurately adjusting the verticality of the upper steel column 8. In addition, the adjustment process does not require the steel wire rope to pull the top of the upper steel column 8, thereby avoiding the problem of deformation caused by tension on the top of the upper steel column 8.

[0030] like Figure 1 , Figure 3 As shown, the base 1 includes two support bodies 11 symmetrically arranged on the outside of the lower steel column 9, the two support bodies 11 extend outward in the transverse direction respectively and the adjacent ends are detachably fastened to the outside of the lower steel column 9 by fastening steel belts 2, the outer ends of the two support bodies 11 are respectively connected to the jack support seats 3 extending upward; the jack 4 includes two and is respectively installed on each jack support seat 3, the movable ends of the jack 4 extend inward relative to each other and are respectively connected to an adjusting top plate 5, the upper and lower sides of the adjusting top plate 5 are symmetrically provided with outer inclined surfaces 51 to form a laterally arranged isosceles triangle or isosceles trapezoidal structure.
