Description
Technical field
The invention belongs to building structure field, more particularly to a kind of novel compositions steel plate shear force wall.
Background technology
In recent years, China's Development of High-rise Buildings is rapid, and various high-rise, high-rise buildings continue to bring out.Steel plate shear force wall because
It has many advantages, such as that high capacity, ductility are good, energy dissipation capacity is strong, meets skyscraper to performances such as structural elements intensity, rigidity
High request.Steel plate shear force wall is generally divided into two major classes：First, pure steel plate shear force wall, two, combined steel plate shearing force wall.
Pure steel plate shear force wall will generate out-of-plane buckling when lateral displacement is larger, and cause steel plate due to lacking out of plane constraint
The bearing capacity and deformability of shear wall decline.After reversed load is subject to, steel plate shear force wall bearing capacity, which is substantially all, to be lost
It loses and it is difficult to generates again.Since pure steel plate shear force wall is all using steel, the material characteristics based on steel, clean steel plate
The fire resistance of shear wall is poor.Secondly, steel plate shear force wall is during larger wind load or geological process, due to the change of steel plate
Shape sends the larger similar buckling sound beaten a drum, and usability is bad.
Combined steel plate shearing is a kind of a kind of structure that concrete and pure steel plate shear force wall is made to cooperate together by force.But
The ductility of concrete and steel differs greatly, if combined steel plate shearing force wall has occurred larger lateral displacement, concrete and pure
Steel plate shear force wall will be difficult to co-ordination, may result in concrete and participate in stress and crack so that concrete loses original work
With.The steel frame of combined steel plate shearing force wall under reciprocating load, first combined steel plate shearing force wall can be to surrounding mixed
Concrete board is squeezed so that this part of concrete slab is destroyed by gradual squeeze, and secondly connecting bolt also can be to its periphery
Concrete slab is squeezed, it will gradually concrete is caused constantly to depart from steel plate so that and concrete slab is completely ineffective, and
The very big buckling sound will be sent by losing the built-in steel plate of concrete slab protection, influence the performance of combined steel plate shearing force wall.
The content of the invention
The present invention provides a kind of novel compositions steel plate shear force wall, the group to solve technical problem present in known technology

Bolt, it is characterised in that：Two blocks of precast prestressed concrete plates being arranged on outside built-in steel plate two sides are further included, it is pre- at two pieces
Two layers of two dimension prestressing muscle is each equipped in prestressed concrete plate processed；Be provided on two blocks of precast prestressed concrete plates with
Multiple connection screw threads formation of respective side installs multiple bolt mounting holes of cooperation one by one, is respectively provided at each bolt mounting hole
There is the collar bolt buffer strip contacted directly with being connected bolt；A nut piece is respectively connected in the end of each connection bolt, it is described
Nut piece is by the thread bush part that is threadedly coupled with bolt is connected to be formed and is arranged on the clamp portion of thread bush outer end and forms, and presses
Plate part is pressed on the end of corresponding collar bolt buffer strip and the area coverage of clamp portion is buffered more than correspondence position collar bolt
The area of band；Periphery buffer strip is provided in the edge of two blocks of precast prestressed concrete plates, two pieces precast prestressed
Concrete slab is in contact by respective periphery buffer strip with the medial surface of frame, the periphery buffer strip and collar bolt buffering
Band uses weak concrete material or resiliency materials.
Preferably：Left and right newel post is steel column, profile steel concrete column, steel pipe column or steel core concrete column.
Preferably：Upper and lower crossbeam is section steel beam or girder with rolled steel section en cased in concrete.
Preferably：The collar bolt buffer strip uses rubber nested structure, and rubber sleeve is flush-mounted in corresponding bolt mounting hole.
The invention has the advantages and positive effects that：
1st, the present invention is respectively provided with precast prestressed concrete plate in the both sides of built-in steel plate, in precast prestressed concrete plate
Two layers of two dimension prestressing muscle is set, and when prefabricated thickness of slab is smaller, it is larger that precast slab can give built-in steel plate to provide
Flat out of plane constraint；Further, since have initial compression by two layers of two dimension prestressing muscle in precast prestressed concrete plate,
Can slow down or the cracking for avoiding prefabricated board under action of pulling stress or other destruction.
2nd, the present invention is respectively provided with precast prestressed concrete plate in the both sides of built-in steel plate, is all provided on the both sides of built-in steel plate
Putting can prevent that steel from losing bearing capacity rapidly when being subject to fire and causes casualties, while also strengthen to a certain extent
The soundproof effect in room.
3rd, the present invention uses collar bolt buffer strip in precast prestressed concrete plate with being connected the junction of bolt so that steel
Plate shear wall is subject to first to crush collar bolt buffer strip when larger lateral displacement or makes collar bolt buffer strip that flexible deformation occur,
And precast prestressed concrete plate is protected not to be damaged.
4th, periphery buffer strip is set at the position that the present invention is connected in built-in steel plate with upper lower girder steel and left and right newel post, makes steel
Plate shear wall first crushes buffer strip when larger lateral displacement is subject to or makes collar bolt buffer strip that flexible deformation occur, from
And precast prestressed concrete plate is protected not to be damaged.
5th, the nut piece that the present invention uses is special nut structure, which can limit the ring around connection bolt
The displacement of bolt buffer strip outwardly convex, simultaneously because its area is more than the area of collar bolt buffer strip, to a certain extent
The plane outer displacement of precast prestressed concrete plate can be limited.
To sum up, which is effectively protected the complete of prestressed concrete plate in larger lateral displacement
Whole property improves the ductility of combined steel plate shearing force wall.
