Embodiment Construction

[0033] The present invention is further illustrated below by means of embodiments in conjunction with the accompanying drawings.

[0034] Taking the buckling-constrained support arranged in a herringbone shape as an example, the upper node of the support is as follows figure 1 As shown, the first steel plate 1 and the second steel plate 3 are respectively located outside the inner stirrup 4 of the concrete beam, and the inner stirrup 4 of the concrete beam is located outside the inner longitudinal bar 5 of the concrete beam. The internally threaded steel bar 2 of the embedded part is connected, the first steel plate 1 and the second steel plate 3 are respectively provided with plug welding holes, and the internally threaded steel bar 2 of the embedded part is welded to the first steel plate 1 and the second steel plate 3 at the plug welding holes; A support connection gusset plate 6 is located below the second steel plate 3, a second support connection gusset plate 8 is conne...

Abstract

The invention belongs to the technical field of node connection of architectural structure, in particular to a vertical reinforced concrete component, that is, a connection node of a buckling-restrained brace (BRB), which consists of steel plates, internal-thread steel bars for embedded parts, internal stirrups for concrete beams, internal longitudinal bars for concrete beams, support connection node plates, support node stiffening plates, buckling-restrained supports, internal stirrups for concrete columns and internal longitudinal bars for concrete columns, wherein, two steel plates are connected by the internal-thread steel bars for embedded parts; plug welding holes are formed on the steel plates; steel bars are welded with a first steel plate and a second steel plate at the plug welding holes; a first support connection node plate is located at the upper part of the first steel plate or at the lower part of the second steel plate; a second support connection node plate is connected with the first support connection node plate; one end of the second support connection node plate is fixed at the upper part of the first steel plate or the lower part of the second steel plate, and the other end thereof is connected with the buckling-restrained brace; and the support node stiffening plates are fixed at one side of the first support connection node plate. The invention solves the problems that steel support connection nodes are difficult to be mounted in a concrete frame, structural steel needs punching when being embedded in a concrete component, and stirrups and longitudinal bars are arranged with difficulties; and the invention has the advantages that the construction is convenient, the stress performance of connection is good, and steel materials can be saved, therefore, the invention has wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of node connection of building structures, and in particular relates to a reinforced vertical concrete member-buckling constraint support connection node. Background technique [0002] Reinforced concrete frame structures are widely used and have a history of hundreds of years, and have the following advantages: [0003] (1) Take local materials. In reinforced concrete structures, sand and stones account for a large proportion, while cement and steel bars account for a small proportion. Sand and stones can generally be provided near the construction site. [0004] (2) Durable and fire-resistant. The steel bars are buried in the concrete, and the concrete protection is not easy to rust, thus improving the durability of the structure. When a fire occurs, the reinforced concrete structure will not be burned like a wooden structure, nor will it reach the softening temperature quickly and be destroyed like a s...
