Description
Technical Field
The utility model relates to a double entry steel pipe concrete corner post-girder steel node in the building engineering field mainly is applicable to industry and civil building structural design field.
Background
The structural design of the corner post is a core component of building frame plus structural design, particularly the anti-seismic design of a frame structure, and because the damage of the center post is greater than that of the beam in the earthquake process, the damage of the corner post is generally greater than that of the side post and the middle post, therefore, the anti-seismic design of the special frame structure in the structural design generally adopts a strong post, a weak beam, a strong corner post and a weak middle post.
At present, a hollow box-shaped square steel pipe is generally adopted for connecting a steel beam or a steel reinforced concrete beam, and a form that the steel pipe concrete column is connected with the steel beam or the steel reinforced concrete beam is also adopted, so that the bending resistance of the node is relatively good, but under the condition of earthquake action horizontal force, in order to ensure the integral rigidity of the structure, especially an earthquake area with high earthquake resistance requirement, the integral rigidity of the structure can be ensured only when the section of the steel pipe column or the steel pipe concrete column is designed to be large enough, the weight of the steel pipe column is inevitably large due to the design, the difficulty is increased for the construction and hoisting of the steel column, on one hand, the construction cost is increased, and meanwhile, the waste of construction steel is caused, and on the other hand, the use space of the building is damaged due to the increase of the section of.
Disclosure of Invention
In order to solve the problem of corner post earthquake resistance of the existing frame structure building, particularly the defects of the design of common steel pipe concrete columns in earthquake areas with high earthquake resistance requirements, and meet the requirements of construction units on the use functions of the building under the condition of economy and reasonableness as much as possible, the composite steel pipe concrete corner post-steel beam node comprises a composite steel pipe concrete column and two steel edge beam connecting pieces which are vertical to each other, wherein the composite steel pipe concrete column consists of outer square large steel pipes, round small steel pipes, stiffening plates and concrete poured in gaps, the outer square large steel pipes and the central round small steel pipes are concentric, the outer square large steel pipes and the central round small steel pipes are connected by the stiffening plates, the stiffening plates are respectively connected with the outer square large steel pipes and the central round small steel pipes in a welding manner, and the two mutually vertical surfaces of the outer square large steel pipes are respectively welded with the two steel edge beam connecting, the connecting mode between connecting piece and the steel limit is even adopts the riveting mode, the pterygoid lamina that the steel boundary beam and the square big steel pipe in the outside link up is widened, compound steel pipe concrete corner post-girder steel structure can be used for as the form of a structural joint in the building structure design, the space between the square big steel pipe in the outside and the circular little steel pipe in center and little steel pipe inner space concreting, after the concrete sets up and reaches intensity, it is a lot of more than ordinary post-beam node rigidity, can be used to the regional frame construction of earthquake that high antidetonation required.
