Abstract
A node energy dissipater belongs to energy consumption shock absorption control technical field. The node dissipater includes a column component (1) and a beam component (2). Viscous-elastic material (3) is filled between the column component (1) and the beam component (2), which are integrated by the viscous-elastic material (3). The column component (1) and the beam component (2) are provided with sockets (5). The socket (5) is a section of arc, with the beam and column node as a circle center, 1/2-2/3 times of the beam component (2) side length as radius and 12-20 degree as a center angle. Under the function of repeated force, the column component (1) and the beam component (2) generate relative displacement and the viscous-elastic material (3) generates reciprocating shearing deformation, so as to dissipate energy. The utility model can greatly improve the beam and column node capability of energy consumption with the improvement extent about 40%-50%.
Description
Technical field
The node energy consumer is a kind of auxiliary energy-dissipating device, is mainly used in the node power consumption of building structure and bridge, belongs to the energy dissipation and damping control technical field.
Background technology
Domestic existing energy-dissipating device is used on the rod member more at present, or in the body of wall, can not effectively be used for the node place of concrete structure, and at the structure of energy-dissipating property difference, the energy-dissipating property that improves node is crucial.The much more external modes of frictional damping sheets that adopt solve the node power consumption, but that the frictional damping sheet installs is cumbersome.In order to improve the energy-dissipating property of structure, we are by having researched and proposed the node energy consumer.
The utility model content
The utility model provides a kind of device, helps structure a part of earthquake energy that dissipates.This device construction is simple, cheap, the power consumption effect is remarkable, easy to maintenance, can be widely used in the antidetonation area.
Structure of the present utility model comprises on the post assembly 2 on the assembly 1 and beam as shown in Figure 1; It is characterized in that: be filled with viscoelastic material 3 on the post on assembly 1 and the beam between the assembly 2, on the post on assembly 1 and the beam assembly 2 be combined into integral body by viscoelastic material 3; On the post on assembly 1 and the beam assembly 2 all have groove 5; Groove 5 is to be the center of circle with assembly 1 node on assembly on the beam 2, the post, doubly is radius with the 1/2-2/3 of 2 length of sides of assembly on the beam, is one section arc of central angle with 12 °-20 °.1 and 2 produce relative displacements under power effect repeatedly, make 3 to produce reciprocal shear strain, thus dissipation energy.
The groove 5 wide 20mm that are not less than are 5-10mm deeply.The effect of groove 5 not only can increase the shearing friction between 1,2, and guarantees that the relative displacement between 1,2 is a rotation formula.
On the post on assembly 1 and the beam assembly 2 thickness be 20-40mm, if the too thick load that can increase bean column node, too thin meeting is owing to shear strain each other damages.1,2 and base rolling be one, can avoid because the damage that brings of welding can guarantee not drawn down in working order bad to greatest extent.
The minimum thickness of viscoelastic material 3 is 10mm.The requirement of this thickness is assurance and can combines closely between 1,2, can guarantee good elastic-plastic deformation again.The general high molecular polymer that adopts is as asphalt rubber, superplasticity silicone rubber etc.It is toughness both, and good elasticity is arranged again, can play the effect of rock-steady structure, simultaneously again can the outside input of dissipative structure energy.
This node energy consumer can increase the damping of structure, and the input energy of dissipative structure can be widely used in earthquake areas, and this brings huge benefit for the economy and the social development of China, has broad application prospects.

The specific embodiment
The structure of node energy consumer is as shown in Figure 1: on the post on assembly 1 and the beam thickness of assembly 2 be 20mm, they and base are rolling to be one, hold bolt 4 holes on the base successfully, with beam, post center intersection point is the center of circle, 2/3 times with 2 length of assembly on the beam is radius, with 15 ° is that central angle is left a current interruption type groove 5, and wide being taken as in 20mm is 5mm deeply.The effect of groove 5 not only can increase the shearing friction between 1,2, and guarantees that the relative displacement between 1,2 is a rotation formula.Afterwards,,, be combined into integral body, with 1 and 2 integral body, be separately fixed on post and the beam again by bolt 4 as asphalt rubber through over cure (referring to the vulcanisation operation of rubber) effect and viscoplasticity 3 with assembly 2 on assembly on the post 1 and the beam.1 and 2 produce relative displacements under power effect repeatedly, make 3 to produce reciprocal shear strain, thus dissipation energy
This node energy consumer has good power consumption, can be used in the district that provides fortification against earthquakes of various earthquake intensitys.Adopt this node energy consumer to make structure have good anti-seismic performance.Be the power consumption situation that adopts node before and after the node energy consumer below, as can be seen from the figure, the raising by a relatively large margin of node energy consumer the energy dissipation capacity of bean column node, increase rate can be about 40%-50%.
