Description

The Huge Steel Open that a kind of floor compartment connects supports and the practice
Technical field
The present invention relates to a kind of bracing or strutting arrangement of building structure, the Huge Steel Open that particularly a kind of floor compartment connects supports and the practice.
Background technology
Along with rising to of China's economic level, the progress of building technology, increasing complicated Super High stands erect in metropolis.These complicated super highrise buildings generally adopt the form of structure of " mega-frame-Core Walls Structure ".In order to structure can obtain larger integral rigidity and good shock resistance, Huge Steel Open to be set between colossal column and support.
The giant frame structure system adopting band Huge Steel Open to support, significantly alleviates the adverse effect that traditional Steel-concrete Composite " concrete inner core is strong, and shaped steel urceolus is weak " produces structure.Under the prerequisite realizing multi-way prevention, reduce concrete core cylinder Stiffness Deterioration, stress redistribution under rarely occurred earthquake and, to the detrimental effect of shaped steel outside framework, improve the general safety deposit of structure.
Because Huge Steel Open supporting section is larger, it generally adopts welding box-shaped steel cross section, and it will meet the flakiness ratio limit value of regulation and stipulation and prevent component partial unstability, and for this reason, Huge Steel Open supports often needs setting to put more energy into floor to meet code requirement.And arrange in the middle part of Huge Steel Open support webs full wafer put more energy into floor time, not only Huge Steel Open supports and not easily constructs with the connection of huge post and the close post of each floor, and to support self cross section welding procedure also not easily, also create the waste of steel, the construction period can be caused to extend, the construction quality supported not easily ensures, cost is also high.
Summary of the invention
The Huge Steel Open that the object of the present invention is to provide a kind of floor compartment to connect supports and the practice, Huge Steel Open can be solved support and huge post connection construction problem, under the prerequisite meeting its strength and stability, the problem of supporting welding assembling inconvenience can be solved, can also cost be saved again.
The technical solution adopted in the present invention is that the Huge Steel Open that a kind of floor compartment connects supports and the practice for achieving the above object, and the Huge Steel Open that this floor compartment connects supports and comprises the edge of a wing 1, web 2, floor 3, floor connecting elements 4; Article two, web 2 is parallel to each other, and two floors 3 are arranged at web 2 perpendicular bisector and are positioned at same plane, and welds respectively with each web 2, leaves gap in the middle of two floors 3; After floor 3 has welded with web 2, web 2 welds with the edge of a wing 1 again, and the described edge of a wing 1 is welded on floor 3 two ends, and two edges of a wing 1, the common assembly weldings of web 2 become box-type section; Article two, the gap location that floor 3 leaves finally welds floor connecting elements 4; All components are by the above-mentioned Huge Steel Open support connecting to form floor compartment and connect, and its cross section is day font.
The making step that this Huge Steel Open supports is as follows:
S1 web 2 welds with floor 3, and floor 3 is arranged on web perpendicular bisector, can open and get groove accurately to locate and to ensure welding quality, get groove if can ensure that welding quality also can not be opened and directly weld during welding floor 3;
S2 web 2 welds with the edge of a wing 1, and its welding position is apart from the twice edge of a wing, web 2 edge thickness of slab;
The component that S2 welds by S3 carries out assembly welding and becomes box-type section;
S4 welds floor connecting elements on floor 3, on itself and Kai Qu slope, floor 3 junction, is beneficial to carry out docking with floor 3 and welds, and final composition Huge Steel Open supports.
Compared with prior art, the present invention can obtain following beneficial effect.
Web perpendicular bisector welding floor and web local buckling can be prevented with connecting elements welding between floor, meet the requirement of ratio of height to thickness, and solid plate frame is easier welding huge supporting section than using, and can also reduce rolled steel dosage, reduces cost.Solve the problem of supporting welding assembling inconvenience simultaneously, accelerate speed of application, reduction of erection time, minimizing cost.
