Illustrate be gap width be have to it is reserved because H profile steel inner core 100 be pressurized when can have lateral expansion, it is necessary to have pre-
The space stayed deforms to discharge this demi-inflation, and otherwise anti-buckling energy-consumption section inner core 120 is with regard to direct and anti-buckling confining part 200
It contacts and surrender energy consumption can not be carried out.In addition, the thickness of cushion block 203 has to be larger than the edge of a wing thickness of H profile steel inner core 100, while U
The height of type groove steel 201 must be smaller than the height of the groove 101 of H profile steel inner core 100, in this way match set up use could be in H
Reserve the gap width of design between Steel core inside 100 and anti-buckling confining part 200, the design in gap with reference to Fig. 3 (2-2) and
Shown in Fig. 3 (3-3).
The diameter and arrangement spacing of the high-strength bolt 10 of anti-buckling energy-consumption section L2 are according to the friction-anti-buckling energy-consumption
Support ultimate bearing capacity design value is designed.
Third walks, the assembling of friction energy-dissipating section L1.
As shown in figure 4, first, two ends anti-buckling energy-consumption section L2 are positioned opposite, it is empty in order to reserve certain deformation
Between, it is not directly contacted with therebetween, gap width d1, as shown in figure 5, being determined according to component design variations;
Secondly, oval slot hole, the ellipse are opened up in friction cover board 302 and 301 corresponding position of friction U-type groove steel
Slot hole number, size and position are corresponded with the oval slot hole on the 100 end edge of a wing of the inner core;
Finally, using high-strength bolt 10 by frictional constraint component 300 (friction cover board 302 and the U-type groove steel 301 that rubs) and institute
Inner core 100 is stated closely to connect.
Number and the pretightning force needs of the high-strength bolt 10 of friction energy-dissipating section L1 are determined according to sliding power has been designed.
In order to avoid the anti-buckling confining part of the frictional constraint component 300 and anti-buckling energy-consumption section L2 of friction energy-dissipating section L1
200 contact with each other during the work time, as shown in figure 5, equally there are gap, gap width d therebetween2It needs to be set according to component
Meter deformation determines cannot be less than d simultaneously1。

Inner core (100) is the H profile steel of local segment edge of a wing machining, the wing of one end of the non-segment of cutting in inner core (100) both ends
It is formed with several oval slot holes on edge, and friction material is pasted after the end blasting treatment, which is divided into described
The local segment edge of a wing cutting end part of the friction energy-dissipating section inner core (110) of inner core (100), the inner core (100) is divided into the inner core
(100) anti-buckling energy-consumption section inner core (120);
Anti-buckling confining part (200) includes two pieces of U-type groove steel (201), two cover plates (202), four pieces of cushion blocks (203) and several
High-strength bolt (10),
Two pieces of U-type groove steel (201) are respectively embedded into the groove (101) of the anti-buckling energy-consumption section inner core (120) of the inner core (100)
Interior, four pieces of cushion blocks (203) are respectively embedded into the inner core (100) edge of a wing cutting portion under the clamping of upper and lower two cover plates (202)
In gap, wherein the thickness of the cushion block (203) is slightly larger than the edge of a wing thickness of the inner core (100), the U-type groove steel (201)
Height be slightly less than the inner core (100) groove (101) height so that the inner core (100) and anti-buckling confining part
(200) there are gaps between, meanwhile, the U-type groove steel (201), cover board (202), cushion block (203) corresponding position be formed with use
In the circular hole of assembly high-strength bolt (10), above-mentioned anti-buckling confining part (200) is located in by high-strength bolt (10) in described
Anti-buckling energy-consumption section inner core (120) surrounding of core (100), at this point, completing the L2 assemblings of anti-buckling energy-consumption section;
An anti-buckling energy-consumption section L2 is assembled again according to above-mentioned same steps;
Frictional constraint component (300) includes two pieces of friction U-type groove steel (301), two pieces of friction cover board (302) several high-strength bolts
(10), and the friction U-type groove steel (301), friction cover board (302) on the contact surface of the inner core (100) at sandblasting
Friction material is pasted after reason,
Friction energy-dissipating section inner core (110) end of two anti-buckling energy-consumption section L2 is positioned opposite, and do not contact therebetween there are
Gap is to ensure enough deformation spaces, gap length value d1,
Meanwhile oval slot hole is formed on the friction U-type groove steel (301), friction cover board (302), and the ellipse is long
Number, size and the position in hole and the oval slot hole on friction energy-dissipating section inner core (110) edge of a wing of the inner core (100)
It corresponds,
Two pieces of friction U-type groove steel (301) are rubbed at two pieces be respectively embedded under cover board (302) is clamped up and down two it is anti-buckling
Two anti-buckling energy-consumption section L2 are connected in the groove (101) of the friction energy-dissipating section inner core (110) of the section that consumes energy L2, and pass through high-strength spiral shell
Bolt (10) makes two anti-buckling energy-consumption section L2 closely connect to get the friction-buckling-restrained energy-dissipation,
Wherein, the middle portion of the friction-buckling-restrained energy-dissipation of frictional constraint component (300) positioning is that friction consumes
It can section L1;Also, do not contact that there are gaps between the frictional constraint component (300) and two groups of anti-buckling confining parts (200)
To ensure enough deformation spaces, gap length value d2, and gap width d2Not less than d1;
Meanwhile the yield force design value for playing sliding power design value and being less than anti-buckling energy-consumption section L2 of the friction energy-dissipating section L1.
2. a kind of friction-buckling-restrained energy-dissipation according to claim 1, it is characterised in that the inner core (100) and anti-
Gap width between buckling-restrained component (200) is 1mm-2mm.
3. a kind of friction-buckling-restrained energy-dissipation according to claim 1 or 2, it is characterised in that as the inner core
(100) the non-segment of cutting cross section of H profile steel is not less than twice of segment of cutting cross-sectional area.
