Specific embodiment
Comparative example one can consume for prefabricated assembled concrete beam-concrete column connecting node for the ease of replacement
Energy connection component, the first selection is the pre-buried fashioned iron in beam such as CN105780960A, and the fashioned iron of prominent beam is utilized to connect energy consumption
Component.This mode, can also apply and girder steel.Above scheme is excessive in the moment capacity decline of beam-ends, and only fashioned iron is held
Moment of flexure is carried on a shoulder pole, and concrete does not undertake moment of flexure.For this purpose, inventor, which has abandoned, utilizes the edge of a wing replacement dissipative member on structural steel connecting member
Thought.Second of selection is such as CN105525679A, the setting energy consumption stick between beams of concrete-column, using energy consumption stick come real
Now consume energy.But energy consumption stick is cast in composite beam, replaces inconvenience；And more importantly, in mechanical mechanism
On, energy consumption stick is in tension and compression Cyclic Loading, is actually the fixing iron member using energy consumption stick two sides when consuming energy stick tension
Shearing force between concrete transmits the pulling force of energy consumption stick, this is higher for the intensity requirement of concrete and fixing iron member,
And when consuming energy stick compressive buckling, it is also possible to generate destruction to concrete.
As shown in Figure 1, being the scheme of comparative example 1, comprising: concrete column 1, the second beams of concrete 2-2, concrete column 1
Cylinder has the first short beam 2-1, using Alveolus type or shaped-steel joint between the first short beam 2-1 and the second beams of concrete 2-2
Connection type connection；First short beam 2-1 is embedded with the first vertical muscle 3-1, the second beams of concrete 2- of prominent first end face short beam 2-1
The upper and lower side of 2 end is provided with tongue and groove 2-3, and the vertical muscle 3-2 of the second of the second beams of concrete 2-2 stretches out tongue and groove end face, and first is vertical
Muscle 3-1 is corresponded to each other with the second vertical muscle 3-2；Energy consumption bar member 4 is connected between the first vertical vertical muscle 3-2 of muscle 3-1 and second.
After energy consumption bar member 4 is installed, the fill concrete in tongue and groove；The concrete and the first short beam filled in tongue and groove
Flexible dielectric layer is provided between 2-1, the second beams of concrete 2-2.
As shown in Fig. 2, the first taper steel bushing is respectively adopted in energy consumption bar member 4 and the first vertical muscle 3-1, the second vertical muscle 3-2
4-1, the second taper steel bushing 4-2 connection；Consume energy bar member 4 both ends have shape of threads, sectional area muscle 3-1 vertical compared with first,
Second vertical muscle 3-2 is big；First taper steel bushing 4-1, the shape of the second taper steel bushing 4-2 are identical.When installation, first by the first cone
The vertical muscle of shape steel bushing 4-1 and first is threaded togather, the second taper steel bushing 4-2 and the second vertical muscle are threaded in one
It rises, and the second taper steel bushing 4-2 is first mobile to the direction of the second vertical muscle, it then will energy consumption bar member and the first taper steel bushing
The other end of 4-1 is threadedly coupled, and is then rotated the second taper steel bushing, is moved to the direction of dissipative member,
First, combine advantage of both CN105780960A, CN105525679A: the stick that will consume energy is directly vertical with beam
Muscle connection does not need the anchoring piece that energy consumption stick is arranged again.
Second, in the effect of the upper and lower surfaces setting tongue and groove of the second beams of concrete 2-2, first is that in order to weaken the anti-of beam-ends
Curved rigidity, so that plastic hinge moves on on beams of concrete from cylinder, so that energy consumption stick energy consumption；Second is that energy consumption stick is arranged in upper and lower table
In the tongue and groove in face, in order to the installation and replacement of the stick that consumes energy.
Third, energy consumption stick compressive buckling energy consumption, if the bending deformation of energy consumption stick is excessive, concrete can be also crushed.If
The concrete of energy consumption stick is connect with beams of concrete, is crushed meeting so that beams of concrete loses bearing capacity.And the application is to energy consumption stick
Anti-buckling concrete is not involved in stress, broken to have an impact to the bearing capacity of beams of concrete.And in order to mention energy consumption
Steel plate can be arranged in the outside of concrete in the anti-buckling performance of stick.
4th, the connection of energy consumption stick and the first vertical muscle, the second vertical muscle is a difficult point.Energy consumption stick and the first vertical muscle pass through first
After taper steel bushing is connected through a screw thread, energy consumption stick cannot rotate again, pass through second the preparatory second vertical muscle spiral shell of taper steel bushing
Line connection, and the second taper steel bushing screws in the second vertical muscle, after consume energy stick and the first taper steel bushing are installed, then by the
Two taper steel bushings reversely rotate, so that the second taper steel bushing links together with energy consumption stick.
The problem of comparative example one is: the second taper steel bushing needs mobile distance larger in connection, and the second cone
Shape steel bushing is moved on the second vertical muscle, and therefore, the distance that the second vertical muscle stretches out beams of concrete is also longer.
In view of the above deficiencies, comparative example two is proposed: as shown in figure 3, the first, second taper steel bushing is changed to
