Abstract
The utility model relates to a steel column node structure, it includes lath and vertical structure muscle, and the lath encloses to weld around the outside bracket of steel column, forms square frame construction, and this square frame construction's inboard fixed vertical structure muscle, lath and bracket welded connection form wholly, wrap up the node region. The utility model discloses saved the manual work and the material of the regional stirrup of on-the-spot bending and ligature node, saved the cost, improved the operating efficiency.
Description
Technical Field
The utility model relates to a steel construction engineering, specific steel column node structure that says so.
Background
In recent years, a 'steel-concrete combined structure' is widely applied to modern reinforced concrete structure buildings, the structure gives full play to the characteristics of two materials of steel and concrete, reduces the steel consumption, lightens the self weight of the structure, shortens the construction period, and is a better building structure form. It is common practice in construction to reinforce stirrups in the joint areas of the steel members to increase the integrity between the steel structure and the concrete. As shown in the following figures: the middle position is a cross steel rib column, vertical structural steel bars are uniformly distributed around the steel rib column, and transverse stirrups bound around the node area are used for fixing the vertical steel bars. And after the steel bars are bound, formwork erecting and concrete pouring are carried out on the outer sides of the steel bars, so that the whole structure becomes a steel-concrete combined structure.
Disclosure of Invention
The utility model discloses aim at overcoming prior art's defect, provide a steel column node structure, solve the fixed vertical reinforcing bar in node area, increase the wholeness effect of whole building behind the concrete placement.
In order to solve the technical problem, the utility model discloses a realize like this:
a steel column node structure which characterized in that: it includes lath and vertical structure muscle, and the lath encloses to weld around the outside bracket of steel column, forms square frame construction, and vertical structure muscle is fixed to this square frame construction's inboard, and the lath forms wholly with bracket welded connection, wraps up the node area.
The steel column node structure, its characterized in that: the flange plate and the post body of bracket adopt full penetration welding, and the bracket web adopts fillet weld to weld.
The steel column node structure, its characterized in that: the thickness of the steel plate strip is 10 mm.
The utility model has the advantages that: installation procedures such as purchasing, bending and binding of on-site civil engineering stirrups in a pillar corbel joint area are eliminated, construction progress can be accelerated, and construction cost is saved;
the laths welded on the steel column bracket are welded with the vertical steel bars, so that the structural integrity is improved;
the concrete in the node area is well bound, and the concrete is not easy to damage.
Drawings
The invention will be described in further detail with reference to the following drawings and embodiments:
fig. 1 is a schematic structural diagram of the present application.
Fig. 2 is a schematic plan view.
Detailed Description
As shown in fig. 1 and 2: a steel column node structure comprises steel strips 3 and vertical construction ribs 4, wherein the steel strips are welded around a bracket 1 outside a steel column 2 in a surrounding mode to form a square frame structure, the vertical construction ribs are fixed on the inner side of the square frame structure, the steel strips and the bracket are welded to form a whole, and a node area is wrapped; the flange plate and the column body of the bracket are welded completely through fusion, and the web plate of the bracket is welded by fillet weld; the thickness of the steel plate strip is 10mm, and the steel plate strip is uniformly distributed around the node area of the column in a surrounding mode. The detailed diagram design deepens the diagram in the model according to the thought, and the diagram is processed by a structure factory. After the plate strip is fed by a factory, the plate strip is bent by a bending machine. After the bracket is installed, the bent lath is welded with the bracket, and meanwhile, the vertical steel bars and the inner sides of the bent laths are welded to fix the vertical steel bars. The steel plate strips and the steel columns are connected into a whole through welding, so that the concrete 5 is well bound, and the concrete is not easy to crack due to bending of floors.
For a steel-concrete combined structure, how to ensure the integrity between the steel structure and the concrete in the combined structure and meet the requirements of the strength, the rigidity and the stability of the combined structure are the key points of the construction of the combined structure. The invention improves the design of the steel structure node, and adopts PL10 × 100mm laths welded around the bracket of the steel column to form a square frame structure. The vertical concrete reinforcing steel bars are fixed on the inner side of the frame structure and can be used for replacing stirrups in the joint area of the conventional construction method of the engineering. The steel plate strips and the brackets are welded and connected to form a whole body to wrap the node areas, so that the whole anti-seismic performance of the structure is improved, the building quality of the steel-concrete combined structure is improved, and cracks are not easy to generate. The square frame that forms welds with the bracket, and the reuse welding is fixed vertical reinforcing bar for steel column, frame lath, vertical reinforcing bar three form a whole. And bending the bent steel plate strip by using a bending machine after the bent steel plate strip is fed, and welding the steel plate strip and the pillar bracket after the bracket is installed. When concrete is poured, the transverse stirrups do not need to be bound in the node area, and the vertical steel bar direct contact is welded on the steel plate strips. The lath replacing the stirrups has regular shape, light dead weight and easy batch production, saves labor and materials for bending and binding the stirrups in the node area on site, saves cost and improves the working efficiency.
