Description
Technical field
The invention belongs to building engineering fields, and in particular to it is a kind of can quick assembling self-locking FRP profile bean column node.
Background technique
Modern architecture is faced with the harsh environments such as more and more highly corrosives, alternation of wetting and drying, this gives traditional reinforced concrete
The durability of soil structure causes grave danger.The problems such as in order to fundamentally avoid corrosion, utilize the good high property of rotproofness
Energy composite material substitution steel are extremely effective processing modes.And FRP material not only high-strength light, also there is good corrosion resistant
Corrosion and very strong designability are a kind of good alternative materials.There are many replace steel using FRP profile at present
Application in Building case, wherein majority belongs to fabricated construction system.
And in fabricated construction system, although the components such as beam, column are easily achieved the factorial production, quality is relatively easily protected
Card, but bean column node is all highly dependent on greatly situ wet operation, and quality is not easy to guarantee, to seriously constrain its development.Currently,
Assembled beam-column node type of attachment can be divided into three categories: one kind is poured after precast concrete column and precast concrete beam
Method connection, this method is first with the intersection cooperation of longitudinal reinforcement beam-column at node, the casting concrete again after lifting component is in place, to reach
To connection purpose；Second class is the connection of steel core concrete column and precast concrete beam, mainly includes with connections with stiffening ring, ring
Girder connection, reinforcing bar circulating type node etc. are for the non-punching node of representative and with bracket punching node, reinforcing bar penetration type node, cross
Gusset-type joint etc. is the punching node of representative；Third class is the node connection in assembling type steel structure, mainly with weld job
Be bolted as representative.
Above-mentioned preceding two classes joint structure is complicated, pours difficulty, and there are the local failures of column to make lacking for bearing capacity reduction
Point.And due to there is no reinforcing bar (replacing reinforcing bar to bear pulling force with FRP) in novel beam, so not being suitable for embed FRP profile
The node connection of FRP pipe concrete column, the new assembly-type RC structure that case flute profile FRP profile concrete combination beam is representative.
Also due to there is no steel in the novel quick assembled type structural system, so third class node connection type (welding and bolt
Connection) also it is not suitable for.
Summary of the invention
In view of the deficiencies of the prior art, the object of the present invention is to provide it is a kind of can quick assembling self-locking FRP profile beam
Column border node, the node use prefabricated components assembled in situ, and simple structure and easy for construction farthest improves construction efficiency
And it is easy to quality control.The node will not only cause local damage to column simultaneously, but also will not generate to the pouring of pipe inner concrete
Any influence can guarantee the safety of main structure to greatest extent, provide safeguard for people's life security.
To achieve the above object, it is provided by the invention can quick assembling self-locking FRP profile bean column node, feature exists
