Description
Technical field
The invention belongs to building fields, and in particular to a kind of prefabricated filled type buckling restrained brace structure of twin-core plate.
Background technique
With the development of building trade, frame structure has been commonly used in skyscraper.However frame structure
Shock resistance is poor, and especially when China requires gradually to pay attention to building aseismicity, buckling restrained brace is as earthquake resistant construction
Can be pressurized also can tension, the lateral displacement of frame structure can be greatly reduced, improve the shock resistance of structure, to improve whole knot
The shock resistance of structure.Meanwhile buckling restrained brace can be used in new construction, can be used for the reinforcing work of existing building
Journey has very big use space.
Traditional filled type buckling restrained brace structure often waits core plates and outer sleeve in casting concrete constraint material
It is directly poured therebetween after completion of processing, long processing time, process is tedious, and it is real etc. to be easy to cause concrete not pour
Disadvantage, in addition its core component of traditional buckling restrained brace is generally single plate, and energy-dissipating property is poor.
Summary of the invention
In view of the defects existing in the prior art, the purpose of the present invention is to provide a kind of prefabricated filled type bucklings of twin-core plate about
Bundle branch support structure.
In order to reach the above object, the technical scheme adopted by the invention is that:
A kind of prefabricated filled type buckling restrained brace structure of twin-core plate, including the filling of sleeve, twin-core plate, precast slab
Material, the twin-core plate are mounted in sleeve, are provided between sleeve and twin-core plate and between two core plates of twin-core plate pre-
Concrete slab filler material processed.
The sleeve includes end welding plate, channel steel, welding steel, opens that there are two T-type mouth, the welderings in the end welding plate
It connects steel plate to be weldingly fixed on the upper lower flange of channel steel, the end welding plate is welded on channel steel both ends.
Ribbed stiffener is respectively welded in the one side both ends of two pieces of core plates of the twin-core plate, and one is welded in the middle part of same side
A circle bloom.
The precast slab filler material is spliced by three kinds of precast slabs, the first is rectangular slab, is not opened
Any hole；Second in the intermediate round hole for being provided with one with the round bloom same size of core plate welding；The third is one
End is intermediate to be provided with notch, and to ribbed stiffener, there are the spaces of sliding.
It further include non-cohesive material, the non-cohesive material is coated between twin-core plate and precast slab filler material, is risen
To the effect of lubrication.
Compared with prior art, the present invention has the advantages that following substantive distinguishing features outstanding and significant:
The present invention, using twin-core plate unit, substantially increases disappearing for support to improve traditional buckling-restrained bracing member
The ability for consuming seismic energy is used as filler material by the way of precast slab splicing, greatly shortens support process time, avoid
Concrete does not pour the defects of real, is connect with gusset plate using the method welded again after build-in, improves the secured of node
Degree.

Specific embodiment
Present invention processing is described further with specific example with reference to the accompanying drawing.
As shown in Figures 1 to 10, the prefabricated filled type buckling restrained brace structure of a kind of twin-core plate, including sleeve, twin-core plate
1, precast slab filler material 3, the twin-core plate 1 are mounted in sleeve, between sleeve and twin-core plate 1 and twin-core plate 1
Two pieces of core plates between be provided with precast slab filler material 3.
The sleeve includes end welding plate 2, channel steel 5, welding steel 6, opens that there are two T-type mouth, institutes in the end welding plate 2
It states welding steel 6 to be weldingly fixed on the upper lower flange of channel steel 5, the end welding plate 2 is welded on 5 both ends of channel steel.
Ribbed stiffener 4 is respectively welded in the one side both ends of two pieces of core plates of the twin-core plate 1, and welds in the middle part of same side
One round bloom 7.
The precast slab filler material 3 is spliced by three kinds of precast slabs, the first is rectangular slab, is not opened
Any hole；Second in the intermediate round hole for being provided with one with 7 same size of round bloom of core plate welding；The third is one
End is intermediate to be provided with notch, and to ribbed stiffener 4, there are the spaces of sliding.
It further include non-cohesive material, the non-cohesive material is coated between twin-core plate 1 and precast slab filler material 3,
Play the role of lubrication.
The prefabricated filled type buckling restrained brace structure fabrication process of twin-core plate of the invention is as follows:
The production of twin-core plate 1, precast slab filler material 3 is completed first.
Secondly, bottom precast slab filler material is placed on channel steel web, non-cohesive material is coated, later by one
Block core plate coats non-cohesive material, by middle layer precast slab on bottom precast slab filler material on core plate
Filler material is installed on core plate, coats non-cohesive material, then second piece of core plate is installed precast slab filler material in middle level
On, non-cohesive material is coated, then top layer precast slab filler material is mounted on core plate, finally welds welding steel 6
It is connected on the upper lower flange of channel steel 5, twin-core plate 1 and precast slab filler material 3 is enclosed in sleeve.
Finally, by the reserved opening of 1 end of twin-core plate difference insertion end portion welding plate 2, by end welding plate 2 and channel steel 5 with
And welding steel 6 is welded.Ribbed stiffener 4 is respectively welded in core plate end, and is purged welding slag, component is thrown
This structure is obtained after the processing such as light, antirust.
