Abstract
The utility model discloses a kind of hinged column base structure of Steel Portal Frames, belong to steel building field.Including steel column, column root-plate, cushion block, shear key, column bolt, fixture, C20 pea gravel concretens layer, concrete foundation layer, it is characterised in that：The shear key is connected to the middle position of column root-plate bottom in the width direction by column bolt and fixture, the fixture is angle steel, quantity is two, it is located at shear key two ends respectively, fixture is while be welded on column root-plate side, while being welded on shear key, the shear key level is embedded in concrete foundation layer top, it is provided between the steel column bottom plate and shear key in gap, its gap and pours C20 pea gravel concretens layer.The utility model is reasonable in design, connects safe and reliable, convenient to install, construction is quick, it is to avoid situation about being constructed again because needing to remove most of concrete foundation when the displacement of steel kind design inserts is severe occurs, and saves construction cost.
Description
Technical field
The utility model belongs to steel building field, and more particularly to a kind of Steel Portal Frames are hinged
Suspension column structure.
Background technology
In recent years, with China's expanding economy, China turns into output of steel big country in the world, and building iron in 2015
The developing goal of structure, is that the steel using amount for striving for annual national construction steel structure reaches the 6% of steel total amount.As can be seen here, send out
It is the new policy about construction t echnology of China to open up construction steel structure.As low cost, installation effectiveness is fast, recycles high portal-rigid frames
Steel structure of light-weight building, into one of current most widely used construction steel structure, as connection steel column and concrete basis, influences whole
The steel column base structure of body building structure stability, preferably using flat hinged column base.Common hinged column base is by column root-plate, post
Pin crab-bolt, stiffener, shear key is constituted, and crab-bolt bears whole axle powers, the frictional force of shearing then between bottom plate and concrete
And shearing-resistant member is born, and pedestal anchor bolt is connection basis and the key point of superstructure, therefore crab-bolt construction quality good
Bad total quality and the safe handling for directly affecting lightweight steel construction.But this suspension column structure crab-bolt needs embedding depth deep enough
Degree, but in foundation grouting, it is easy to cause pre-buried stay bolt to shift, eventually cause the inconvenience of construction.
Utility model content
The utility model aims to solve the problem that above mentioned problem, there is provided one kind is reasonable in design, connects safe and reliable, the convenient door installed
The hinged column base structure of formula rigid frame steel structure of light-weight building.Avoid because needing to remove most of when the displacement of steel kind design inserts is severe
The situation that concrete foundation is constructed again occurs.
The technical solution adopted in the utility model is：
A kind of hinged column base structure of Steel Portal Frames, including steel column 1, column root-plate 2, cushion block 3 resist
Cut key 4, column bolt 5, fixture 6, C20 pea gravel concretens layer 7, concrete foundation layer 8, the column root-plate 2 is welded on steel
On post 1, cushion block 3 is provided between the column root-plate 2 and column bolt 5, it is characterised in that：The shear key 4 passes through suspension column spiral shell
Bolt 5 and fixture 6 are connected to the middle position of the bottom of column root-plate 2 in the width direction, and the fixture 6 is angle steel, quantity
For two, respectively positioned at the two ends of shear key 4, the one side of fixture 6 is welded on the side of column root-plate 2, while being welded on shear key 4
On, the level of shear key 4 is embedded in the top of concrete foundation layer 8, and gap is provided between the steel column bottom plate 2 and shear key 4,
C20 pea gravel concretens layer 7 is poured in its gap.
Further, the shear key 4 is angle steel, and its length is more than the width of column root-plate 2 and the width sum of fixture 6.
Further, the quantity of column bolt 5 is two, respectively positioned at the web both sides of steel column 1, longitudinally through suspension column bottom
Plate 2, shear key 4 and C20 pea gravel concretens layer 7.
The utility model compared with prior art, with following advantage：
The structure level sets longer shear key, is then connected with column bolt and fixture with column root-plate, centre two
Secondary pouring C20 pea gravel concretens layer, relative to other hinged column base structures, shearing resistance and axial force-resisting are greatly enhanced, and are also had certain
The effect of bending resistance square, steadiness and security are improved, easy for installation, and construction is quick, saves construction cost.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings, but the utility model is not subject in any way
Limitation, any changes and modifications made based on the utility model training centre, belongs to protection domain of the present utility model.
A kind of hinged column base structure of Steel Portal Frames, as shown in Fig. 1 to 2, including steel column 1, suspension column
Bottom plate 2, cushion block 3, shear key 4, column bolt 5, fixture 6, C20 pea gravel concretens layer 7, concrete foundation layer 8, the suspension column
Bottom plate 2 is welded on steel column 1, and the fixture 6 is vertically welded in the two ends upper surface of shear key 3 according to the width of bottom plate,
Corresponding position offers two bolts hole on shear key and the steel column bottom plate.
The lower end of column bolt 5 is fixed through shear key bolt hole with nut.
The shear key 4 for being connected with column bolt 5 and fixture 6 is embedded in concrete foundation 8 top surface of layer.
Have between the steel column bottom plate 2 and shear key 4 and secondary pour C20 pea gravel concretens layer 7.
The nut of pedestal anchor bolt 5 is tightened after the completion of lifting, by fixture 6 weld with steel column bottom plate 2.
The distance between described two fixtures 6 being welded on shear key 4 are equal to the width of firm column base plate 2
The shear key 4 and fixture 6 are angle steel.The shearing resistance key length is more than the width of column root-plate 2 and fixation
The width sum of part 6.
In construction, the shear key for being connected with fixture and bolt is embedded in coagulation by casting concrete basal layer first
The top surface of earth foundation layer, when intensity reaches requirement by the steel column lifting with steel column bottom plate in place, carries out second pouring C20 thin
Stone concrete layer, finally tightens column bolt, fixture is welded together with column root-plate edge.
