The construction method of the described suspension column device for steel structure slipping, comprises the steps;
Step 1, rail to be shelved in concrete foundation, and with rail clamp, rail to be fixed, every block rail clamp be spaced apart 300 ~ 500mm;
Step 2, clamp angle steel is welded on rail clamp;
Step 3, steel column base plate pad is welded in bottom steel column, then bottom plate reinforcing rib point is welded in the junction of steel column and steel column base plate;
Step 4, hemispherical contact steel plate is welded on the vertical steel plate medial surface of limiting plate fastening devices;
Step 5, be welded on steel column base plate bottom surface by the vertical steel plate of limiting plate fastening devices, adopt fillet weld to connect, two blocks of vertical steel plates are respectively apart from rail center line 100mm ~ 150mm;
Step 6, transverse stiffener is welded on the junction of steel column base plate and vertical steel plate;
Step 7, superstructure bearing is connected with steel column and can carries out sliding construction.
The construction method of the above-mentioned suspension column device for steel structure slipping, for avoiding steel column base plate welding deformation excessive, step 3 is divided into
Step 3.1, with bottom plate reinforcing rib, steel column and steel column base plate to be linked together;
Step 3.2, steel column base plate and steel column are welded together, adopt melt-through weld, during location, steel column is positioned at the center of steel column base plate.
This suspension column device is by being displaced downwardly to rail both sides by the horizontal reacting force of steel work, and with the contact point of hemispherical contact steel plate as whole suspension column device and rail, so, even if top steel work has slight inclination, also can not have influence on rail makes it topple, thus substantially increase the stability of steel work when slippage, and then improve the efficiency of construction of steel work when sliding construction and safety.
