Description

A kind of assembly concrete connecting structure of beam column nodes

Technical field

This utility model relates to buildings in general structure, is particularly used for prefabricated assembled concrete structure The connection of general structure component.

Background technology

Precast reinforced concrete structure is one of important directions of China's building structure development, and it is conducive to me The development of state's building industrialization, the raising production efficiency saving energy, development Green environmental-protection building, and favorably In improving and ensureing construction engineering quality.In place of but fabricated construction self there is also some shortcomings.Prefabricated The link position of assembly concrete frame structure is frequently located in position of joints, owing to having two in its work progress Secondary cast-in-place, thus cause the switching performance of node poor compared with cast-in-place concrete structure, in level in earthquake Be easily destroyed under the repeated action of load, it is difficult to meet in earthquake resistant design code the globality of frame structure and Stability requirement.A large amount of seimic disaster census find that prefabricated assembled concrete structure connects the destruction of node point connection The most serious.

For realizing " strong column and weak beam ", the failure mode of " the weak component of strong node ".Traditional fabricated construction leads to The antidetonation of building structure post and bean column node is improved usually through the cross section and increase bean column node arrangement of reinforcement increasing post Performance, but this is passive passive seismic countermeasures.There is following asking in the method for existing bean column node Aseismic Design Topic: (1) bean column node arrangement of reinforcement too much causes reinforcing bar intensive, makes troubles to construction, and waste material; (2) cross section increasing post makes the rigidity of post increase, and is unfavorable for the dissipation of seismic energy, even can put in earthquake Violent earthquake effect, makes structure produce more serious destruction.

Authorization Notice No. is that the utility application of CN204850069U discloses that " a kind of assembled mixes Solidifying civil engineering builds middle precast beam column connected node ", this connection node includes that precast beam, prefabricated post and node connect structure Part, wherein, described node connects structure and includes reinforcing bar, sleeve and cast-in-place concrete;During assembling, described steel Muscle is passed through the prefabricated post beam respectively with the precast beam of prefabricated post both sides and indulges muscle and be connected by sleeve, after mixing stirrup Secondary cast-in-place concrete forms node connecting elements and prefabricated post is linked together with precast beam.Thus may be used Knowing, above-mentioned connection node still have employed traditional type of attachment, and the join dependency secondary of beam column is cast-in-place, joint Point position arrangement of reinforcement is intensive, causes constructing extremely difficult, and second pouring makes the link position of first after-pouring material easy Produce crack so that the quality of connection of node is difficult to ensure that, affects anti-seismic performance and the stress performance of node.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of assembly concrete bean column node and connects knot Structure, this node connecting structure has the connection of node, and to be independent of secondary cast-in-place, and node quality of connection is reliable, anti- The advantage that shock stability is good.

This utility model solves the technical scheme of above-mentioned technical problem:

A kind of assembly concrete connecting structure of beam column nodes, this node connecting structure includes precast beam, prefabricated Post and node connecting elements, it is characterised in that

Described node connecting elements is shearing-type steel plate damper, the end plate at this shearing-type steel plate damper two, One piece fixing with described prefabricated post side is connected, and another block is fixed with the end face of precast beam and is connected, and, described The web of shearing-type steel plate damper is perpendicular to horizontal plane.

Node connecting structure described in the utility model, wherein, described prefabricated post side and the end of precast beam Face is equipped with built-in fitting, the end plate at described shearing-type steel plate damper two and described prefabricated post and precast beam On built-in fitting be separately fixed at together.

The further improvement project of node connecting structure described in the utility model is, described built-in fitting divides It is not provided with one group of connecting bolt, the end plate at described shearing-type steel plate damper two and described prefabricated post and in advance Built-in fitting on beam processed is separately fixed at together by described connecting bolt.

This utility model has the advantages that

1, use shearing-type steel plate damper as node connecting elements, eliminate connect at node intensive and join Muscle, it is to avoid secondary is cast-in-place so that assembling construction is the easiest, and the connection of node is the most reliable.

2, under small earthquake or weak wind are bestirred oneself and used, structure stratified deformation is less, and shearing-type steel plate damper is in In the elastic working stage, certain additional stiffness can be provided to structure, ensure the stability of building structure;Greatly Earthquake or high wind are bestirred oneself under use, and structure stratified deformation is relatively big, and antivibrator enters elastoplasticity working stage, utilizes The shearing lag return deformation of web and flange inflection deform the energy of the outside input that dissipates, and can be effectively reduced The earthquake response of structure.
