Embodiment
Comparative example one, for prefabricated assembled concrete beam-concrete column connecting node, it can be consumed for the ease of changing
Energy connection component, the first selection is the pre-buried shaped steel in beam such as CN105780960A, utilizes the shaped steel of prominent beam to connect power consumption
Component.This mode, can also be applied and girder steel.Such scheme declines in the moment capacity of beam-ends excessive, and only shaped steel is held
Moment of flexure is carried on a shoulder pole, and concrete does not undertake moment of flexure.Therefore, inventor has abandoned changes dissipative member using the edge of a wing on structural steel connecting member
Thought.Second of selection is such as CN105525679A, the setting power consumption rod between beams of concrete-post, using the rod that consumes energy come real
Now consume energy.But it consumes energy, rod is cast in composite beam, changes inconvenience;And what is more important, in mechanical mechanism
On, power consumption rod is in tension and compression Cyclic Loading, and when consuming energy rod tension, it is actually the fixing iron member using rod both sides of consuming energy
Shearing force between concrete transmits the pulling force of power consumption rod, and this is higher for the intensity requirement of concrete and fixing iron member,
And when consuming energy rod compressive buckling, it is also possible to produce destruction to concrete.
As shown in figure 1, be the scheme of comparative example 1, including:Concrete column (1), the second beams of concrete (2-2), concrete column
(1) cylinder carries the first short beam (2-1), between the first short beam (2-1) and the second beams of concrete (2-2) using Alveolus type or
The connected mode connection of shaped-steel joint;First short beam (2-1) is embedded with the first vertical muscle (3- of prominent first short beam (2-1) end face
1), the upper and lower side of the end of the second beams of concrete (2-2) is provided with tongue and groove (2-3), and the second of the second beams of concrete (2-2) is vertical
Muscle (3-2) stretches out tongue and groove end face, and the first vertical muscle (3-1) and the second vertical muscle (3-2) are mutually corresponding;First vertical muscle (3-1) and second
Power consumption bar member (4) is connected between vertical muscle (3-2).
After power consumption bar member (4) installation, the fill concrete in tongue and groove;The concrete and first filled in tongue and groove are short
Flexible dielectric layer is provided between beam (2-1), the second beams of concrete (2-2).
As shown in Fig. 2 the first taper is respectively adopted with the first vertical muscle (3-1), the second vertical muscle (3-2) in power consumption bar member (4)
Steel bushing (4-1), the connection of the second taper steel bushing (4-2);Power consumption bar member (4) both ends be threaded shape, its sectional area compared with
First vertical muscle (3-1), the second vertical muscle (3-2) are big;The shape phase of first taper steel bushing (4-1), the second taper steel bushing (4-2)
Together.During installation, first the first taper steel bushing (4-1) is threaded togather with the first vertical muscle, the second taper steel bushing (4-2)
It is threaded togather with the second vertical muscle, and the second taper steel bushing (4-2) first moves to the direction of the second vertical muscle, then will consumption
Can bar member be threadedly coupled with the other end of the first taper steel bushing (4-1), then rotate the second taper steel bushing, to consume energy structure
The direction movement of part,
First, combine advantage of both CN105780960A, CN105525679A:The rod that will consume energy is directly vertical with beam
Muscle connects, it is not necessary to sets the anchoring piece of power consumption rod again.

Bending rigidity so that plastic hinge is moved on on beams of concrete from cylinder so that power consumption rod power consumption;Second, power consumption rod be arranged on it is upper and lower
In the tongue and groove on surface, in order to the installation and replacing of the rod that consumes energy.
3rd, the compressive buckling power consumption of power consumption rod, if the bending deformation of power consumption rod is excessive, concrete can also crush.If
The concrete of power consumption rod is connected with beams of concrete, and it, which is crushed, can cause beams of concrete to lose bearing capacity.And the application is to the rod that consumes energy
Anti-buckling concrete is not involved in stress, and it crushes and the bearing capacity of beams of concrete will not be had an impact.And in order to mention power consumption
The anti-buckling performance of rod, steel plate can be set in the outside of concrete.
4th, power consumption rod and the first vertical muscle, the connection of the second vertical muscle are a difficult points.Power consumption rod and the first vertical muscle pass through first
After taper steel bushing is connected through a screw thread, power consumption rod can not be rotated again, and muscle spiral shell is indulged by the second taper steel bushing advance second
Line connects, and the second taper steel bushing screws in the second vertical muscle, after consume energy rod and the first taper steel bushing installation, then by the
Two taper steel bushings reversely rotate, to cause the second taper steel bushing to be linked together with power consumption rod.
