Utility model content
For overcoming the shortcoming of above-mentioned prior art, the utility model proposes a kind of orthogonal-diagonal lattice hollow sandwich panel ceiling for storied building unit of assembled integral Steel Space grid box structure, adopt bar to connect in succession, its welding capacity only has total welding capacity 1/5, cost-saving favourable popularization.
The technical solution of the utility model is:
The orthogonal-diagonal lattice hollow sandwich panel ceiling for storied building unit of assembled integral Steel Space grid box structure, comprises column, crossbeam and span centre support bar, also comprises x
2to ST-1, ST-2, ST-3, ST-4, ST-5, ST-6, the each Two bors d's oeuveres of ST-7 or single unit Vierendeel truss of spelling, described Vierendeel truss welding forms the continuous laced beam of multispan, along x
3direction is installed T shape member by bolt, is equipped with pin on the upper T shape component grid edge of a wing, and stands and have template assembling reinforcement, described x at upper T shape component grid
2to with x
3direction is and 45 ° of directions that cross of mast axis.
Described Vierendeel truss welding forms welding formation Two bors d's oeuveres and spells laced beam with single, then is spliced to form the continuous laced beam of multispan.
Described Two bors d's oeuveres laced beam is divided into two unit A and B, and wherein A unit left end is connected with H steel column, only has upper and lower T steel member to be cantilever position, and A unit right-hand member has montant and node, the additional interim diagonal brace of plane, and in plane, cantilever end adds vertical temporary supporting angle steel,
The beneficial effects of the utility model are:
When Site Welding workload significantly declines, also exempt the strong connection operations such as high-strength bolt, cost-saving.Superstructure as shown in Figure 1, disregards a seat place node, amounts to 210 nodes, total weld seam n
1=210 × 5=1050 bar, wherein 840 weld seams complete at factory floor, when field welding 210 (20%) significantly reduces Site Welding workload, cancel the strong operations that connect such as high-strength bolt, in reducing construction costs, guarantee that factory manufactures, field erected assembled integral operation is implemented.
