The steel pipe concrete structure includes: round steel tube concrete, rectangular (square) steel tube concrete and polygonal steel tube concrete. From the steel pipe to the restraint angle of concrete, the restraint effect of circular steel tube is better, nevertheless because rectangle (square) steel pipe concrete is changeed on building space and is handled, the node is connected conveniently, fire prevention panel changes and pastes, and rectangle (square) steel pipe concrete structure's application constantly increases. The steel pipe and the inner core concrete bear the external load together, and the effective combination of the two building materials greatly improves the comprehensive benefit. In recent years, the steel pipe concrete structure has become an important direction for the development of structural engineering by virtue of excellent anti-seismic performance and construction performance, but the node is an important part of the structural engineering design and is also a construction difficulty, and the safety of the structure and the construction cost are related, so that the reasonable selection node is very important for the structural design. At present, the construction forms of the nodes are various, but most of the nodes have complicated structures, high construction difficulty and unclear transferred load, and the mechanical properties of the nodes and the simplicity and the economy of construction cannot be consistent; the node has the advantages of good stress, large material consumption of the node with high integral rigidity, economy, unreasonable property and complex construction, most of the nodes have simple structures, convenient construction and economy, the node with saved materials can not bear large load, and the node is easy to damage in the using process. Meanwhile, for a long span structure, when a general column cannot reach a required span, node connection between two columns is needed. Therefore, an assembly type steel pipe concrete column joint connecting structure which is high in assembly rate, simple and convenient to construct, good in stress performance and economic benefit and safe and reliable in connection is urgently needed, and is very necessary.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art not enough and provide one kind increase roof beam ability of shearing, increased post bending resistance bearing capacity, improved the effect that the post bore load in the middle of the steel core concrete structure, optimized construction process, the route of node biography power is more clear and definite for the steel core concrete column accords with the steel core concrete column node connection structure of building antidetonation design specification more.
The utility model discloses a following embodiment realizes:
the utility model provides a steel core concrete column node connection structure, includes the first post and the second post of perpendicular setting, first post and second post are the square steel tube cylinder, first post and second post interconnect end have been poured the concrete in advance for hollow, all the other parts, the external diameter of the link of second post and the internal diameter phase-match of first post link, the link of second post inserts in the link of first post and through a plurality of bolt fastening or welded fastening, be provided with the grout hole with the link intercommunication near the overlap joint on the second post, first post and second post are connected the back, are connected into whole through the concrete of pouring into in the link in the grout hole.
In this embodiment, the grouting hole of the second column is a hole having a V-shaped section.
In this embodiment, an observation hole for observing the grouting quality is provided on the second column at the opposite side of the grouting hole.
In this embodiment, all set up a plurality of bolt holes on lapped part on first post and the second post, and the bolt hole position on first post and the second post corresponds each other, and first post and second post are fixed through installing the bolt interconnect in the bolt hole.
In this embodiment, the bolt holes are provided in two faces of the first column that face the second column.
