Description
Technical Field
The invention relates to the technical field of buildings, in particular to a steel structure column base structure.
Background
The steel column plug-in column base is simple in structure, convenient to construct, safe and reliable, and widely applied to steel structure column base connection. The plug-in column base has good anti-seismic performance through practical inspection of earthquake action. In the specification of anti-seismic design for buildings GB 50011-2010, the insertion depth of the solid-web steel column must not be less than 2.5 times the height of the section of the steel column, as shown in fig. 1. The insertion depth of the lattice steel column is not less than 2.5 times of the height of the section of the single limb and 0.5 time of the total width of the column, as shown in figure 2. When the section height of the solid-web steel column is larger, the depth of the steel column inserted into the foundation is deepened.
Disclosure of Invention
The invention aims to provide a steel structure column base rigid connection node conversion structure, which is characterized in that in order to reduce the insertion depth of a column base into a foundation, the lower end of a web plate of a solid-web type steel column is cut off, steel plates are welded in the vertical direction on two sides of a flange, reinforcing ribs are vertically welded among the steel plates, a first reinforcing plate is horizontally welded above the steel plates, and the first reinforcing plate is fixedly welded with the steel web plate, the flange and the steel plates; converting the solid-web steel column into two branches of the lattice type steel column; two lattice type steel column cup openings are reserved on a concrete foundation, two branches are inserted into the cup openings, and the internal force of the steel column is transmitted to the foundation through the branches of the lattice type steel column.
Still include the second reinforcing plate, the second reinforcing plate is parallel with first reinforcing plate, the second reinforcing plate and steel web, edge of a wing and steel sheet welded fastening.
The invention has the advantages that:
the stress is clear: the solid-web steel column forms a conversion beam through the first and second reinforcing plates, the stiffening ribs and the column plate, the processing mode is changed, and the stress of the solid-web column base is converted into the lattice column sub-limb axial force;
reduction in insertion depth in construction: according to the anti-seismic design specification, the structural insertion depth meets 2.5 times of the height of the single-limb section of the lattice type steel column and 0.5 time of the total width of the column. In addition, the advantages of simple structure and convenient construction of the plug-in column base are reserved.

Detailed Description
The invention will be further explained with reference to the drawings.
Cutting off the lower end of a web plate 1 of the solid-web steel column, welding steel plates 3 on two sides of a flange 2 in the vertical direction, vertically welding reinforcing ribs 6 among the steel plates 3, horizontally welding a first reinforcing plate 5 above the steel plates, and welding and fixing the first reinforcing plate with the steel web plate 1, the flange 2 and the steel plates 3; converting the solid-web steel column into two branches of the lattice type steel column; two lattice type steel column cup openings are reserved on the concrete foundation 4, two branches are inserted into the cup openings, and the internal force of the steel column is transmitted to the foundation through the branches of the lattice type steel column.
In order to obtain better technical effect, the steel plate reinforcing structure further comprises a second reinforcing plate 7, wherein the second reinforcing plate is parallel to the first reinforcing plate 5, and the second reinforcing plate is fixedly welded with the steel web 1, the flange 2 and the steel plate 3.
After the cup is hoisted in place, the cup mouth is poured with fine stone concrete for the second time and is vibrated to be compact.
The solid-web type steel column section height in structures such as single-layer industrial plants is usually more than or equal to 2 times of the section width, the solid-web type column base is converted into a lattice type column base, and the insertion depth of the steel column is greatly reduced under the condition of meeting the specification.
