Description

A kind of modified assembly concrete connecting structure of beam column nodes

Technical field

The utility model is related to buildings in general construction, and in particular to for the company of prefabricated assembled concrete structural elements Connect.

Background technology

Precast reinforced concrete structure is one of important directions of China's building structure development, and it is conducive to China to build Industrialized development, improve production efficiency energy saving develops Green environmental-protection building, and is conducive to improving and ensure to build work Cheng Zhiliang.But fabricated construction itself there is also some shortcomings part.The connection position of prefabricated assembled concrete frame construction Put and be frequently located in position of joints, it is secondary cast-in-place due to existing in its work progress, so as to cause the switching performance of node mixed with cast-in-place Xtah Crude Clay structure is compared poor, is easily destroyed under the repeated action of horizontal loading in earthquake, it is difficult in meeting earthquake resistant design code Globality and stability requirement to frame structure.A large amount of seimic disaster census find that prefabricated assembled concrete structure connecting node connects The destruction for meeting place is very serious.

To realize the failure mode of " strong column and weak beam ", " strong node weak component ".Traditional fabricated construction is generally by increasing The anti-seismic performance of building structure post and bean column node is improved in the section of huge pillar with bean column node arrangement of reinforcement is increased, but this is passively to disappear The seismic countermeasures of pole.There is problems with the method for existing bean column node Aseismic Design:

(1) bean column node arrangement of reinforcement excessively causes reinforcing bar intensive, makes troubles to construction, and waste of materials;(2) increase The section of post increases the rigidity of post, and the dissipation of seismic energy is unfavorable in earthquake, or even can amplify geological process, produces structure The more serious destruction of life.

Authorization Notice No. discloses a kind of " assembly concrete building for the utility application of CN204850069U In prefabricated beam-column connection ", the connecting node includes precast beam, prefabricated post and node connecting elements, wherein, the node connects Connecing construction includes reinforcing bar, sleeve and cast-in-place concrete;During assembling, it is pre- with prefabricated post both sides respectively that the reinforcing bar passes through prefabricated post The vertical muscle of the beam of beam processed is connected by sleeve, is mixed secondary cast-in-place concrete after stirrup and is formed node connecting elements by prefabricated post Link together with precast beam.It follows that above-mentioned connecting node still employs traditional type of attachment, the connection of beam column according to Rely it is secondary cast-in-place, node location arrangement of reinforcement is intensive, cause construction it is extremely difficult, second pouring makes the link position of first after-pouring material It is also easy to produce crack so that the quality of connection of node is difficult to ensure that, affects the anti-seismic performance and stress performance of node.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of modified assembly concrete bean column node connection Structure, it is secondary cast-in-place that there is the node connecting structure connection of node to be independent of, and node quality of connection reliability, anti-seismic performance is good Advantage.

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

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

The node connecting elements includes shearing-type steel plate damper and sector lead viscoelastic damper, wherein, it is described to cut The end plate at cut type steel plate damper two, one piece is fixedly connected with the prefabricated post side, and another piece is consolidated with the end face of precast beam Fixed connection, and, the web of the shearing-type steel plate damper is perpendicular to horizontal plane;The sector lead viscoelastic damper is arranged on In the lower armpit of precast beam and prefabricated post, its two pieces of connecting plates, one piece is fixedly connected with the side of the prefabricated post, another piece and institute The lower surface for stating precast beam head is fixedly connected.

Node connecting structure described in the utility model, wherein, relevant position difference in described prefabricated post and precast beam Be provided with two of built-in fitting, the shearing-type steel plate damper and sector lead viscoelastic damper respectively with the prefabricated post and pre- Corresponding built-in fitting is fixed together on beam processed.

The utility model has the advantages that:

1st, connection is eliminated as node connecting elements using shearing-type steel plate damper and sector lead viscoelastic damper Intensive arrangement of reinforcement at node, it is to avoid secondary cast-in-place so that assembling construction is more easy, and the connection of node is more reliable.

2nd, under small earthquake or the effect of weak wind shake, structure stratified deformation is less, and shearing-type steel plate damper is in elastic work Make the stage, certain additional stiffness can be provided to structure, ensure the stability of building structure;Bestir oneself use in violent earthquake or high wind Under, than concrete joint, structure stratified deformation is larger, and damper enters elastoplasticity working stage, and the shearing using web is stagnant Return deformation and flange inflection deforms come the energy of the outside input that dissipates, the earthquake response of structure can be effectively reduced.

3rd, the use of sector lead viscoelastic damper makes the bending resistance of beam-column connection higher, coordinates shearing shape steel plate Damper causes bean column node to adapt to more complicated vibration input, and energy-dissipating and shock-absorbing effect is more preferable.
