Description

A prefabricated steel barrel type RCS space node

technical field

The utility model relates to a reinforced concrete composite structure, in particular to an assembled steel plate bucket type RCS space node.

Background technique

The traditional reinforced concrete structure has a long construction period and insufficient energy dissipation capacity, while the cost of the steel structure is relatively high. Reinforced concrete column-steel beam composite frame structure (composite frame consisting of Reinforced Concrete column and Steel beam, referred to as RCS) gives full play to the advantages of different materials of reinforced concrete and steel members, and is a low-cost and high-efficiency structural form.

At present, the application of RCS combined structure is not much in our country, and the theoretical research and engineering practice are far behind foreign countries. The structure of the core area of the RCS composite joint in the prior art is insufficient, and the core area often needs to punch holes on the web of the steel beam to bind the stirrups, which weakens the steel beam section to a certain extent and increases the difficulty of construction. Reduce construction efficiency; the welding process is used in many places in the entire node structure, which also increases the difficulty of construction, reduces the efficiency of construction, and has a certain impact on the steel structure, which is not easy to control; in addition, the steel beam passes through the concrete column as a whole. The assembly of cross-shaped space nodes cannot be realized, and the existence of steel beam flanges is not conducive to concrete pouring and vibration.

The cross splicing plate includes two connecting plates vertically welded together, and a row of third connecting holes are arranged at both ends of the connecting plate;

The ends of the four H-shaped steel beams are respectively spliced with the four ends of the cross splicing plate, and the peripheral barrel staves are located at the angles between two adjacent H-shaped steel beams, and the barrel staves of the peripheral barrel staves The two rows of second connecting holes on the connecting plate are respectively corresponding to the first connecting holes on the adjacent web and the third connecting holes on the cross splicing plate and are fixedly connected by fixing bolts. A closed rectangular steel plate barrel body, the two wing extension plates of the H-shaped steel beam are clamped on the central structure formed by the steel plate barrel body and the cross splicing plate, and the longitudinal steel bars of the reinforced concrete column are surrounded by the The steel barrel body surrounded by the outer barrel staves.

As a further improvement of the utility model, two corners of the extension plate of the wing are cut off to form chamfers.

The assembled steel plate bucket type RCS space node provided by the utility model can be applied in the reinforced concrete column-steel beam frame, which fully utilizes the advantages of the two materials, and not only exerts the good bending resistance of the steel beam, The good compressive performance of reinforced concrete columns is also utilized. The form of partially cutting off the flange not only ensures the force transmission in the core area of the node, but also facilitates construction and vibration. Its parts can be prefabricated in the factory, and the on-site construction is all connected by bolts without welding operation, which greatly improves the construction speed. At the same time, the existence of the steel barrel saves the formwork and enhances the shear resistance of the nodes. Compared with the traditional reinforced concrete structure, the steel beam reduces the structure's own weight, lowers the height of the structure, and increases the usable area.

At the core node (where the beams and columns intersect), the main force-transmitting parts of the two cross-shaped steel beams and the concrete columns are continuous, and the connection structure of the cross splicing plate and the steel plate barrel can ensure the longitudinal reinforcement in the column. Continuous penetration, without cutting or perforating the flange of the steel beam, is also conducive to the pouring of concrete, achieving high efficiency in joint construction.
