Description
Technical field
The utility model belongs to structural engineering technical field more particularly to a kind of steel box column splicing node.
Background technique
As China's increasing environmental pollution, resource constraint enhancing, construction industry recruitment cost rise, tradition is labor-intensive
Construction industry face transition pressure, green building and building industrialization are increasingly becoming the development trend of current building trade.Steel knot
Building is built with prefabrication, in-site installation, material high-strength light, transportation cost are low and green low-carbon environment-friendly is can be recycled
Advantage is the optimum carrier of building industrialization.
The pillar of resistance of super high-rise steel structures, receiving special load and the higher extraordinary steel construction of security level generallys use
Steel box column, steel box column need to carry out merogenesis, factory's segmental machining, scene splicing, lifting according to site operation.Currently,
China's steel building joint connection in site, such as column splices with column, beam and beam splicing, beam and column are connect still with site welding or bolt
It welds based on Hybrid connections, is mostly selected by " more high-rise civil building steel structure node details of construction " (16G519), wherein such as Fig. 1
To shown in Fig. 3, steel box column splices the conventionally employed upper and lower otic placode 6 of node, is positioned using double plate bolt connecting mode,
This traditional connection positioning is simple and practical for small bore steel column, for the steel box column in large-scale or super-huge section, due to
Do not account for the adverse effect of 6 welding deviation of lower ear plate and the double plate changing of the relative positions, scene often occur segmented column dislocation up and down compared with
Big problem causes steel box column to splice low efficiency, influences steel box column joining quality, secondly the soldering of stitching portion, steel
Column section is put more energy into it is difficult to ensure that high quality completion, causes the stitching portion of column often to become structure short slab.
In addition, connection of the Zhong Yejianyan institute for steel column on-site consolidation and column and beam in steel building, by upper and lower
Node area is arranged in column, site welding is reduced, or avoid site welding completely by high-strength bolt connection, without using tradition splicing
Being fixed temporarily for upper lower prop is realized by otic placode 6 and connecting plate 7 in node, but this application be mostly bear the industry of conventional load with
Civilian steel building, steel box column section is smaller, does not account for putting more energy into inside column.For resistance of super high-rise steel structures, bear spy
The steel column of different load and the higher extraordinary steel construction of security level need to be set since its section is big (short side >=1.5m) in section
Ribbed stiffener is set, and uses the splicing node, the processing of seam crossing ribbed stiffener is also it is contemplated that and for the special steel knot for bearing dynamic load
Structure, such as derrick of copper-mine, steel structure bridge construction of structures require to realize using level-one groove full penetration weld upper lower prop etc. it is strong
Connection；It should be used according to the I and II weld seam of " code for acceptance of construction quality of steel structures " GB50205 design requirement complete penetraction and fusion in welding
Ultrasonic examination carries out internal flaw inspection, and when ultrasonic examination cannot judge defect, Ying Caiyong radiographic inspection is right
Live joining quality proposes high requirement, is related to the scene splicing skill of the box arch of such steel construction building at present
Art scheme almost without.
