Description
Technical field
The invention belongs to Shock-proof for building technical fields, and in particular to a kind of Low Yield Point Steel regeneration concrete combined shear
Wall.
Background technique
With the development of human society, the building that the mankind are built is more and more, major at home in order to save soil
Many high buildings and large mansions have all been built in city, a large amount of population and material wealth are had accumulated inside these mansions, so the peace in building
Full property becomes an important problem, and wherein quakeproof and quake-resistant performance is even more an important indicator.Once earthquake disaster, ground occurs
Table building will be destroyed, especially skyscraper.Steel plate concrete combined shear wall has lateral rigidity big and bearing capacity
By force, the features such as ductility is good, energy dissipation capability is strong builds Lateral Resistant System for multi and tall steel building and provides very high safety storage
It is standby, therefore universal use is obtained in skyscraper.Under small shake, faced wall elastic working is rigid with very big structure anti-side
Degree；Under big shake or middle shake, faced wall is plastically deformed by good surrender, has superior energy-dissipating and shock-absorbing ability.
Combined steel plate shear wall antidetonation and ant wind load performance are more stable in comparison, are more able to satisfy super high-rise building
Antidetonation demand.Compound shear wall fills out steel plate and two sides are cast-in-place or precast rc slab forms by interior, passes through between them
Peg is attached.It can be divided into two classes according to construction method: cast in place concrete plate-steel plate combination wall and concrete
Earth mulch plate-steel plate combination wall.The former concrete slab with steel plate is whole pours together, there is no gap, the two deformation association between them
It adjusts, resists horizontal loading jointly；The latter is combined by precast concrete cover and steel plate by high-strength bolt, plate and plate it
Between have certain gap, therefore under small shake effect, the two compatibility of deformation, under middle shake or big shake effect, the two may be sent out
Raw changing of the relative positions sliding.On the one hand the shortcomings that concrete carrying later period Stiffness Deterioration, steel plate out-of-plane buckling can be made up, on the other hand,
The advantage of the two can be shown well.The shear wall simple structure, easy to manufacture and install, size is easy to adjust, and
It can obtain preferable anti seismic efficiency.
It draws materials from materials, existing technical solution uses general steel plate, and absorption energy is not significant under geological process, steel
The hysteresis ability of material can also further get a promotion.Existing technical solution is using concrete aspect, not from green, environmental protection
Consider, is likely to result in the exhaustive exploitation and a large amount of building waste of natural material.
Summary of the invention
The present invention provides a kind of Low Yield Point Steel regeneration concrete compound shear wall, on the one hand to make steel plate in geological process
Under have enough plastic deformations, using its good Hysteresis Behavior, to absorb more seismic energies as far as possible；On the other hand
It resolves building waste and reduces the exploitation to natural material, to meet the requirement of green, environmental protection.
Specific technical solution are as follows:
Low Yield Point Steel regeneration concrete compound shear wall, including shear wall slab and frame；
The shear wall slab includes Low Yield Point Steel regeneration concrete assembled wall board, and assembled wall board is by low yield point steel plate
It is made up of with regeneration concrete plate Welded-Stud Conectors, the surrounding of regeneration concrete wallboard is fixed with low-yield by peg
Steel；
The frame includes the vertical column at both ends, and column upper and lower side passes through horizontal crossbeam respectively and is fixedly connected,
Column and crossbeam form a rectangle frame；
The shear wall is fixed in frame.
The column uses the first I-steel, and crossbeam uses the second I-steel, and the first I-steel cross section is big
In the second I-steel.
It is fixedly connected to otic placode on the Low Yield Point Steel, connecting plate is fixedly connected on the frame, it is described
Connecting plate be fixedly connected by high-strength bolt with frame with otic placode.
For the yield strength of Low Yield Point Steel generally in 80~160MPa, yield strain is only the 1/3 of common iron, yield tensile ratio
It is the 1/2.5 of common iron, deformability is about 2 times of common iron, and elongation percentage can reach 50% when fracture.Low Yield Point Steel
Material has many advantages, such as that yield strength is low, yield tensile ratio is small, anti-low cycle fatigue property is good, elongation is big and plastic deformation ability is strong,
There is good hysteretic characteristic after entering mecystasis, and a large amount of energy can be absorbed in elastoplasticity hysteresis deformation process.
Meanwhile Low Yield Point Steel welding performance, fire resistance, construction method, processing technology and in terms of with it is common
Structural steel has the characteristics that similar.Under geological process, sent out first by the energy consumption that Low Yield Point Steel makes with damping device
Raw surrender enters the plastic stage, absorbs seismic energy using good Hysteresis Behavior, avoids main structure body and main bearing member
There is serious destruction, to protect the safety of whole building.
So-called recycled concrete, be exactly in the building by dismounting discarded concrete by separation, screening, cleaning,
After broken, grain composition grouping is carried out, " recycled aggregate " is made, substituting traditional sand, stone with recycled aggregate, these are natural
Gather materials, is configured to regeneration concrete.Waste and old concrete had both been recycled in this way, also produced new construction material.Meet state
Border Environmental Protection Agency is to green, environmental protection and sustainable definition.
Low Yield Point Steel and regeneration concrete are used for steel plate concrete combined shear wall, to obtain a kind of excellent effect
Compound shear wall.
The present invention has the characteristics that good plasticity using Low Yield Point Steel, the advantages of with compound shear wall, both guarantees to cut
Not deforming under power wall normal operating condition, and guarantee the shear wall energy good absorption seismic energy under geological process.
Using regeneration concrete, harm of the building waste to environment and human body is avoided, and building waste can be allowed to utilize again, is met green
Color, environmental protection, sustainable development requirement.
Compared with prior art, the technical effect that the present invention has are as follows:
1. Low Yield Point Steel has good hysteresis loop, after reaching plastic deformation, more earthquake releases can be absorbed
Energy, low-yield shearing steel plate have the effect of to the energy-dissipating and shock-absorbing of structure it is fairly obvious, to play protection main structure body
Effect.
2. the use of regeneration concrete can reduce the exploitation to natural resources, building waste can also be utilized again, from
And avoid the harm to environment and human body.Meet the orderly National land space layout system of building science appropriateness, green of country's proposition
The industrial system of color circulation low carbon development.
3. use fabricated shear wall, by the cooperation of high-strength bolt and connecting plate by the otic placode and frame on precast shear wall
Frame connects, easy to operate, not high to the technical requirements of construction personnel, and mechanical connecting structure high reliablity, improves
Construction quality, existing fabricated shear wall connection is existing, and difficulty of construction is big, there are problems that larger security risk, while energy
Enough lifting construction efficiency, accelerates construction progress, and has good practicability and economy.
