Abstract
The utility model discloses a steel column and steel girder quake-proof connecting structure. The steel column and steel girder quake-proof connecting structure is characterized in that a stiffening plate is fixedly connected on a steel girder web plate through a bolt, a steel column is connected with a steel girder frange plate in a welded mode, one side edge of the stiffening plate is welded on the steel column through a stiffening plate fillet weld, and two ends of the stiffening plate fillet weld keep a certain distance with the steel girder frange plate. The steel column and steel girder quake-proof connecting structure has the advantages of being capable of enhancing the resistibility of the connecting structure to the structural damage caused by the repeated plastic deformation of the web plate in the earthquake, and therefore safety factor is improved.
Description
Technical field
The utility model relates to steel building structure, more specifically says a kind of steel column and girder steel syndeton.
Background technology
In steel work, need a large amount of girder steels as the floor bracing frame in multistory building or the mill construction, be to adopt steel column to dock welding with " H " section steel beam frange plate full penetration in the prior art, steel beam web plate and post adopt the fillet weld full weld, and perhaps web is not connected with steel column.These forms all fail to consider in the effect of seismic dynamic loading to steel beam web plate.In fact, web thickness is very thin, but the cross section is very large, Gu its ability of bearing dynamic loading is very weak; Show according to interrelated data, steel beam joint in the earthquake in the steel building is main breakdown point, the repeatedly plastic strain that earthquake produces acts on the web place of girder steel, if the load that web can not be subject to passes, to make web produce the distortion supporting capacity that oversteps the extreme limit, will cause collapsing of building when serious.
The utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of steel column and girder steel syndeton are provided, guaranteeing that having connected mode now both docked welding by steel column with " H " section steel beam frange plate full penetration, steel beam web plate and post adopt on the basis that the fillet weld full weld is connected, strengthen the rigidity of web, guarantee the globality of structure, the reloading that earthquake stress is produced can not act directly on the steel beam web plate, weaken or reduce steel beam web plate malformation and destroy, to improve safety factor.
The utility model is that the technical solution problem adopts following technical scheme:
The characteristics of the utility model steel column and girder steel antidetonation syndeton are: be bolted to connection stiffener at steel beam web plate, steel column and girder steel frange plate are welded to connect, and a side of stiffener passes through the stiffener fillet weld seam on steel column; There are a spacer segment distance in the two ends of described stiffener fillet weld and described girder steel frange plate.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, adopts stiffener that steel beam web plate and steel column are connected in the utility model, strengthened the opposing being damaged deformation ability of steel beam web plate, improved safety factor;
2, there are a spacer segment distance in the two ends of the fillet weld of stiffener and girder steel frange plate in the utility model, guarantee that the two ends of stiffener fillet weld can not extend to the girder steel frange plate, have effectively prevented the generation constraint stress, and anti seismic efficiency is good.
3, the utility model simple structure, cost is lower, can be widely used in the building field of antidetonation demand.
Description of drawings
Fig. 1 is the utility model structural representation;
Number in the figure: 1 steel column; 2 stiffener fillet welds; 3 bolts; 4 stiffeners; 5 girder steel frange plates; 6 steel beam web plates; 7 arc crescent holes.
The specific embodiment
Referring to Fig. 1, steel column is to be fixedly connected with stiffener 4 by bolt 3 on steel beam web plate 6 with girder steel antidetonation syndeton in the present embodiment, and steel column 1 is welded to connect with girder steel frange plate 5, and a side of stiffener 4 is welded on the steel column 1 by stiffener fillet weld 2; The two ends of stiffener fillet weld 2 and girder steel frange plate 5 have a spacer segment distance, to prevent constraint stress.
The utility model is on the basis that the existing connected mode of assurance both had been connected by steel column and " H " section steel beam frange plate full penetration docking welding, steel beam web plate and steel column employing fillet weld full weld, by stiffener is set, very effectively strengthened the rigidity of steel beam web plate, guaranteed the globality of structure, the reloading that earthquake stress is produced can not act directly on the steel beam web plate, weaken or reduce steel beam web plate malformation and destroy, improve safety factor.
Claims (2)
