In barb-like setting.
Using the above program, foundation bolt is set by the surrounding in suspension column so that the stress of suspension column is more balanced；Pass through
The one end of foundation bolt away from suspension column is in barb-like setting so that suspension column was more stablized is installed on ground.
Preferably, multiple foundation bolts of same suspension column bottom are both provided with connecting rod between any two.
Using the above program, by setting connecting rod between foundation bolt so that foundation bolt can bear bigger
Vertical force further increases the stability of suspension column.
Preferably, being connected with crossbeam at the top of the column, the crossbeam is fixedly connected by welding or bolt with column.
Using the above program, by bolt or it is welded and fixed so that the connection between crossbeam and column is more secured.
Preferably, being additionally provided with cant beam at the top of the column, the cant beam uses I-steel.
Using the above program, i-beam structure, intensity is high and is easily fixed with the wingceltis item in column or engineering construction.
Preferably, being provided with several struts between the crossbeam and cant beam, the both ends of the strut pass through welding respectively
Or bolt is fixedly installed on crossbeam and cant beam.
Using the above program, by setting several struts to increase the intensity of crossbeam and cant beam.
Preferably, the strut is arranged to angle steel.
Using the above program, the intensity of angle steel is high, by welding or bolt being drawn to be fixedly installed between crossbeam and cant beam, props up
It is more preferable to support effect.
In conclusion the utility model has the advantages that：
By setting reserved block in the suspension column bottom surface of column, when column is acted on be subject to external force, suffered power can edge
Suspension column passes to reserved block, by reserved block and the basic function of being connected to realize balance shearing, by being set in reserved block
Limiting slot, when by slightly expanded concrete final grouting, part concrete enters in limiting slot and in being solidified in limiting slot, makes
Obtaining reserved block can firmly be embedded in shearing resistance slot, add the stability of column, while by limiting slot in suspension column
Wall is obliquely installed, and when filling slightly expanded concrete, what micro- concrete can be more prone to enters in limiting slot and fill up limit
Position slot so that the limit effect of limiting slot is more preferable；The setting of reserved block strengthens the bonding strength between column and basis connection,
Effectively avoid the situation being broken between shear key and suspension column.
