The utility model provides a modular large cross-section steel column base node, it has simple structure, and the cost is low, has better mechanical properties's characteristics.
Description
Technical Field
The utility model relates to a steel column base node field, in particular to modular large cross-section steel column base node.
Background
The steel structure has the advantages of light weight, high strength, high construction speed, short construction period and the like, and is widely applied to industrial and civil buildings. The structure that the steel column is connected with the reinforced concrete foundation at the lower part of the steel column is called a steel column base node.
At present, steel column base node includes steel column, bottom plate, reinforced concrete foundation and four at least crab-bolts, and wherein, the steel column is fixed on the bottom plate, has seted up four at least through-holes on the bottom plate, and the one end of an crab-bolt passes a through-hole and pre-buried in reinforced concrete foundation, and the other end fastens through the nut.
When high-intensity earthquake occurs, especially for the combined type large-section steel column base node, larger uplifting force and bending moment can be generated at the node, so that each anchor bolt is in a complex stress state and is easy to damage. In order to avoid the damage to the steel column base node, the current steel column base node is provided with at least four anchor bolts, and the diameter and the length of each anchor bolt are required to be large enough to ensure the safety of the node structure.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to prior art's current situation, provides a modular large cross-section steel column base node, and it has simple structure, and the cost is low, has better mechanical properties's characteristics.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a modular large-section steel column base node, includes steel column, bottom plate, concrete foundation and a plurality of crab-bolt, the bottom plate passes through the crab-bolt to be fixed on concrete foundation, and the steel column is fixed on the bottom plate, its characterized in that: the steel column is characterized in that boot beams are welded on opposite side walls of the steel column respectively, two partition plates are welded between the two boot beams and located on two sides of the steel column.
As an improvement, rib plates are welded on the outer side walls of the boot beams.
And then, improving, wherein pier column reinforcing steel bars extend out of the concrete foundation, and the upper parts of the pier column reinforcing steel bars are fixedly connected with the steel columns.
And the upper part of the pier column steel bar is welded with the steel column.
And the upper part of the pier column steel bar and the steel column are connected together through bolts.
