Abstract
The invention relates to a connection node structure which is applied to the connection between buckling restrained braces and concrete columns and concrete beams. The connection node structure comprises a pre-buried plastic pipe, connecting steel plates, concrete node members, adjusting threaded rods and supporting connecting steel plates; the concrete columns, the concrete beams, the pre-buried plastic pipe and the concrete node members are formed by integral cast-in-site, the connecting steel plates are pre-buried in the concrete node members and connected with the supporting connecting steel plates through the adjusting threaded rods, and the upper portions of the adjusting threaded rods are provided with threads and nuts used for adjusting height; the supporting connecting steel plates are connected with elastic heads of the buckling restrained braces in a welded mode; anchor bars are arranged in the concrete columns and the concrete beams by the connecting steel plates and pass through the pre-buried plastic pipe to fix anchors in an anchored mode. According to the connection node structure, the stability and the strength of connection nodes between the buckling restrained braces and the concrete columns and concrete beams are improved while the steel quantity used in node connecting is reduced, the bracing length can be adjusted, the structure is simple, the construction is convenient, and the node aesthetics is improved.
Description
Technical field
The invention belongs to building structural element technical field, specifically a kind of connecting joint structure.
Background technology
Buckling restrained brace be a kind of pressurized tension can surrender and not flexing, using steel surrender energy dissipation capacity it is good, hold
The high metalloid surrender type damper of loading capability.Buckling restrained brace application in the structure, can improve structure it is middle shake and
Anti-seismic performance under big shake.Buckling restrained brace is made up of in the vertical core segment, changeover portion and the part of elastic head three.
At present, China's buckling restrained brace is with the Main of reinforced beam, column connected node：In beam, post
The built-in fitting that the pre-buried straight dowel by anchor slab and balanced configuration is constituted（Required according to anchoring strength, can be welded with dowel end
Anchor slab, formed beam, post two sides for monoblock anchor slab built-in fitting）, the then welding node steel plate on anchor slab, buckling restrained brace bullet
Property head is connected using friction type high strength bolt or is welded to connect with node steel plate.Node steel plate also needs to be symmetrically welded to put more energy into sometimes
Rib, for strengthening ribbed stiffener height, thickness and buckling restrained brace elastic head plate height, the thickness phase of node steel stability
Deng.This traditional connecting node way, steel using amount is big, and construction process is complicated, and weld seam is more, it is impossible to adjust bearing length, and construction is missed
Difference is difficult to improve, and to interior of building overall aesthetics certain impact is will also result in.Buckling restrained brace and beam column built from concrete
Connecting node is still left to be desired and improves.
The content of the invention
The invention aims to overcome existing buckling restrained brace and beams of concrete, column connected node steel using amount it is big,
Construction process is complicated, weld seam is more, the deficiency of impact inside configuration overall appearance, there is provided a kind of connecting joint structure, the connection section
Point structure can not only reduce node connection rolled steel dosage, and adjustable support length, without pre-embedded steel slab and dowel, improve construction
Error and easy construction, increase the aesthetic property of node.
To reach above-mentioned purpose, the technical solution adopted for the present invention to solve the technical problems is：
A kind of connecting joint structure, is applied to buckling restrained brace and concrete column, the connection of beams of concrete, including pre-buried
Plastic tube, junction steel plate, concrete joint component, adjusting screw rod and support junction steel plate；The concrete column, beams of concrete,
Pre-buried plastic tube is formed with concrete joint component integral cast-in-situ, pre-buried junction steel plate in the concrete joint component, described
Junction steel plate is connected by adjusting screw rod with junction steel plate is supported, and adjusting screw rod top is provided with the screw thread and nut for adjusting height；
The support junction steel plate is adopted with the elastic head of buckling restrained brace and is welded to connect；The junction steel plate is in concrete column, mixed
Dowel is set in solidifying soil beam to anchor anchor through pre-buried plastic tube.
Compared with prior art, the invention has the beneficial effects as follows：
The present invention subtracts while buckling restrained brace is improved with beams of concrete, the stability of column connected node and intensity
Few node connection steel using amount, adjustable support length, simple structure, easy construction increases node aesthetic property.
