Abstract

The utility model is a kind of anti-seismic strengthening device for reinforced concrete beam column node, is made of dissipative cell, anchor slab, bolt and anchor bolt, and anchor slab anchors to reinforced beam on column by anchor bolt, and dissipative cell is attached by bolt and anchor slab.Dissipative cell is strip mild steel, has bolt hole at both ends, equidistant energy consumption hole is opened up in interlude.There is anchor slab anchor hole and hinged shaft to hold.The device simple structure, of low cost, ductility is good, excellent earthquake resistance, is with a wide range of applications and good engineering value.

Description

A kind of anti-seismic strengthening device for reinforced concrete beam column node
Technical field
The utility model belongs to field of civil engineering, is related to building structure strengthening, more particularly to a kind of to be used for reinforced concrete The anti-seismic strengthening device of native bean column node.
Background technology
The bean column node of reinforced concrete frame structure is crucial structure member, node in building construction and industrial building Core space anti-seismic performance is to influence the key factor of seismic performance for reinforced concrete structure.Before the foundation of modern anti-seismic specification, Gravity laod is the Primary Reference standard of Architectural Structure Design, thus at present these structures cannot meet in region of providing fortification against earthquakes it is anti- Design requirement, especially reinforced concrete beam column node are shaken due to lacking corresponding anti-seismic construction measure, in the effect of seismic force Under it is very fragile;And as Seismic Design Requirements improve, some refer to the reinforced concrete beam column section of old earthquake resistant code design The anti-seismic performance of point is often also difficult to meet existing code requirement.There is presently no effectively reinforcement means and technology, this at The difficult point reinforced for reinforced concrete structure.As earthquake disaster situation is on the rise, reinforced concrete beam column node antidetonation adds Gu new technology and method R&D work is increasingly important and urgent.
Since construction is inconvenient, it is difficult to increase outer plus stirrup or hoop plate around reinforced concrete beam column node core space, Common method is to carry out reinforced concrete beam column node in reinforced concrete beam column node core space wrap carbon fiber cloth at present Core space seismic hardening, but this reinforcement means is only to generate passive bound to reinforced concrete beam column node concrete to make With, and the effect of this passive bound is not highly significant, while it is carbon cloth reinforced after concrete be gradually easy to happen Brittle break, so this reinforcement means still has compared with big limitation.Currently, both at home and abroad, about reinforced concrete beam column node core Heart district reinforcing does not have full maturity technology, bean column node seismic hardening to become the difficulty that resistance of Reinforced Concrete Frames shake is reinforced Topic.
Invention content
In order to overcome the disadvantages of the above prior art, the utility model provides a kind of for reinforced concrete beam column node Anti-seismic strengthening device, the device simple structure, of low cost, ductility is good, excellent earthquake resistance, is with a wide range of applications With good engineering value.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of anti-seismic strengthening device for reinforced concrete beam column node, including:Dissipative cell, anchor slab, bolt and anchor Bolt, two anchor slabs are anchored to by anchor bolt respectively on reinforced beam and column, two dissipative cells by bolt respectively with anchor Plate is attached.
The dissipative cell is strip mild steel, bolt hole is had at both ends, for connecting anchor slab, in centre portion Equidistant energy consumption hole is opened up, for improving its plastic deformation ability.
There are four anchor bolts for anchor slab tool, are held with hinged shaft in centre, and for connecting dissipative cell, when installation ensures energy consumption Element at 45 ° obliquely.
Description of the drawings
Fig. 1 is the anti-seismic strengthening device structural schematic diagram of reinforced concrete beam column node.
Fig. 2 is the structural schematic diagram of dissipative cell.
Fig. 3 is the structural schematic diagram of anchor slab.
In figure:1- reinforced columns;2- reinforced beams;3- dissipative cells;4- anchor slabs;5- bolts;6- anchor bolts; 7- bolts hole;8- energy consumptions hole;9- anchor holes;10- hinged shafts are held.
Specific implementation mode
Such as Fig. 1 to Fig. 3, two dissipative cells 3 are passed through bolt 5 and two anchor slabs 4 by the utility model first when implementing It is connected, then two anchor slabs is respectively fixed on reinforced beam 2 and column 1 by anchor bolt 6, while ensures that dissipative cell 3 exists 45 ° obliquely.
