Description
Technical Field
The utility model relates to a steel construction nodal connection structure.
Background
When the steel structure is designed, due to the influence of building functions, the steel structure column can be only arranged in one direction longitudinally in the middle part of the steel structure column, and the steel column in the other direction cannot be arranged outside the plane and effectively connected with the steel column, so that the problem of out-of-plane instability of the local steel structure column is solved. If the stability outside the plane meets the standard requirement, the section size of the steel structure column is increased artificially, the engineering economy is poor, and even the size of the steel structure column cannot be increased due to the limitation of the building function in many times.
Disclosure of Invention
The utility model aims to solve the problem that a steel construction nodal connection structure is provided, this kind of steel construction nodal connection structure under the safe prerequisite of stability outside guaranteeing the structure plane, both can realize the building function requirement, can reduce engineering cost simultaneously.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a steel structure node connecting structure comprises a single-row steel column and crossed oblique beams connected to the single-row steel column, wherein the crossed oblique beams are connected to the single-row steel column through crossed points of the crossed oblique beams in a welding mode; a node area transverse connecting beam is respectively arranged at the longitudinal two sides of the cross point of the crossed oblique beam and is connected with the crossed oblique beam in a bolted welding manner; the transverse two sides of the cross point of the crossed oblique beams are respectively provided with a node area longitudinal connecting beam, and the node area longitudinal connecting beams are connected with the crossed oblique beams in a bolted welding manner; the end part of the crossed oblique beam is connected with a longitudinal structural beam.
In the technical scheme, the single-row steel column is a common round steel tube column or a common square steel tube column which is only allowed to be additionally arranged along the longitudinal direction of the structure.
In the technical scheme, the crossed oblique beams are crossed steel beams which are welded on the steel columns in a groove welding rigid connection mode, the horizontal included angle of the crossed oblique beams is 30-135 degrees, and the crossed oblique beams are ordinary I-shaped or box-shaped steel beams or other types of solid-web sections.
In the technical scheme, the steel beams are structural longitudinal steel beams and transverse connecting steel beams, and the steel beams are made of I-shaped or box-shaped steel beams or other types of solid-web sections.
In the technical scheme, the bolts in the bolt welding connection are friction type high-strength bolts or pressure bearing type high-strength bolts for connecting the crossed oblique beams, the longitudinal steel bars and the transverse steel beams.
In the technical scheme, the groove welding is a connection welding mode between the crossed oblique beam and the steel column.
The utility model has the advantages that: the cross oblique beams are additionally arranged outside the plane of the node area of the local frame column structure through certain structural measures, a truss with high horizontal rigidity is formed outside the plane, and the local single frame column and other multi-span frame columns form a whole, so that the supporting points are formed outside the plane of the frame column structure, and the stability outside the plane of the steel structure column can be ensured. Under the special structure system, on the premise of ensuring the stability and safety outside the plane of the structural column, the oversize structure of the frame column is avoided, so that the requirement on the building function can be met, and the construction cost is reduced.

Detailed Description
The present invention will be further explained with reference to the drawings and the specific embodiments.
As shown in fig. 1, the utility model comprises a single-row steel column 1 and a crossed oblique beam 2 connected to the single-row steel column 1, wherein the crossed oblique beam 2 is welded and connected to the single-row steel column 1 through a crossed oblique beam cross point 2.1; a node area transverse connecting beam 3 is respectively arranged at the longitudinal two sides of the crossed point 2.1 of the crossed oblique beam, and the node area transverse connecting beam 3 is connected with the crossed oblique beam 2 in a bolted welding manner; a node area longitudinal connecting beam 4 is respectively arranged on the two transverse sides of the cross point 2.1 of the crossed oblique beam, and the node area longitudinal connecting beam 4 is connected with the crossed oblique beam 2 in a bolted welding manner; the end part of the crossed oblique beam 2 is connected with a longitudinal structural beam 5. The longitudinal structural beam 5 is located on the extension of the longitudinal connecting beam 4.
The method comprises the following specific steps:
firstly, the grooves of the crossed oblique beams 2 are welded on the steel columns 1 with equal strength in a factory, then the parts are hoisted and installed on a construction site, then the transverse connecting beams 3 in the node area are connected on the crossed oblique beams 2 in a bolted welding rigid manner, the longitudinal connecting beams 4 in the node area are connected on the crossed oblique beams 2 in a bolted welding rigid manner, the whole node core area is completed, and finally the longitudinal structural beams (general steel beams) 5 are connected on the crossed oblique beams 2.
After the technical scheme is implemented, the rigidity outside the plane of the single-column joint area is enhanced by additionally arranging the crossed oblique beams outside the structural plane, so that the stability outside the plane of the steel-structure column can be ensured. Under the special structure system, the structural column can meet the requirements of building functions on the premise of ensuring the stability and safety outside the structural plane, and meanwhile, the overlarge structural size of the frame column is avoided, and the construction cost is reduced. By taking the structure of the Yanshan project tree house of the Guilin integrated Wanda cultural tourist city as an example, the novel node scheme is adopted, about more than 100 million is saved compared with the conventional node scheme, and certain economic benefit is achieved. And the building function is better realized.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
