Description
Technical field
The present invention relates to the realm of building construction, and wall and frame structure construction are filled in particular to a kind of light block
Technique.
Background technology
Wall is different according to its structure stress situation, there is point of load bearing wall, non-load bearing wall.In frame structure, to those
Maintenance effect is only played, the wall of not load-bearing commonly referred to as fills wall.It is a kind of masonry structure in itself to fill wall, and its weight is general
Undertaken and transmitted by concrete components such as beam, post, plates.It is extremely widespread to fill application of the wall in frame structure, particularly exists
In some high-rise, small high-rise residential structures.
At present, several relatively common Filled-wall materials mainly have：Sintered hollow block and sintered perforated brick, steam pressure sand-lime
Brick, concrete small size hollow building block, autoclave aerated concrete building block.The main making raw material of sintered hollow block and sintered perforated brick
Clay, they have the advantages that sound insulation, it is heat-insulated, insulation, porosity it is big, it is in light weight, be easy to build by laying bricks or stones and paint, be usually used in framework knot
The filling wall and non-bearing dividing wall of structure.Hollow brick is only eight ten ten to percent 7 the percent of solid brick in terms of weight,
The deadweight of wall can thus be mitigated significantly.In addition, both bricks relatively inexpensive in price, are easily received by owner.
Autoclaved lime-sand brick is a kind of solid brick, and lime and sand are the primary raw materials for making autoclaved lime-sand brick.This kind of brick has
Economical and practical, saving clay, do not destroy the advantages that arable land, the building of southern region of China is using more.Concrete small size is hollow
Building block is using sandstone as aggregate, using cement as binder materials, by adding the series of processes such as water stirring, vibration pressurization, maintenance to make
Form.This kind of building block is in light weight, intensity is high, builds simplicity by laying bricks or stones, and the metope built by laying bricks or stones is more smooth, is easy to paint, and can improve construction
Efficiency, reduce construction cost.Sand, flyash, containing siliceous materials such as silicon tailings, and the calcareous material such as lime, cement is steam pressure
The main making raw material of air-entrained concrete building block.This kind of building block lighter weight, there is the characteristics such as good sound insulation, insulation, environmental protection,
Building block, sheet material and the heat insulating products of all size can also be made according to the actual needs simultaneously.If with autoclaved lime-sand brick and
Two kinds of materials for walls of autoclave aerated concrete building block are contrasted, and during masonry panel, the cost of autoclaved lime-sand brick adds than steam pressure
Gas concrete segment is lower.
In construction, autoclaved lime-sand brick be the requirement for meeting anti-crack and anti-seepage, it is necessary to whole linked networks, and steam-pressing aero-concrete
Building block such as only needs at post junction, wall and beam, door-window opening frame at the linked network at part.Built using steam-pressing aero-concrete
This filled wall material of block can be realized with plastering technique and preferably combined, either in terms of masonry quality, or in labor
In terms of fatigue resistance, the better than combination of autoclaved lime-sand brick and plastering technique.Further, since steam-pressing aero-concrete is built in quality
Block is lighter than autoclaved lime-sand brick, therefore beam, the size of post and amount of reinforcement can be reduced in structure design, can substantially reduce engineering
Cost.
Connection as defined in specification between filling wall and frame structure, which can use, is rigidly connected and is flexibly connected two kinds of sides
Formula.It is rigidly connected to refer to combine closely on beam, the post of filling wall and frame structure and builds by laying bricks or stones, and the reinforcing bar by being stretched out in beam, post
Drawknot is carried out, filling wall is formed a kind of integral connected mode with framework.Sent out for the seimic disaster census after all previous earthquake in China
It is existing, often destroyed seriously using rigidly connected filling wall, because filling wall constrains the change of frame structure central sill, post
Shape, the shock resistance of beam, post can be weakened when earthquake occurs, meanwhile, also cause its own destruction very serious.
In view of be rigidly connected technology the defects of,《Code for design of masonry strucres (GB50003-2011)》The 6.3.4 articles suggestion：
When having requirements for fortification against earthquake, filling wall and the flexible connecting method of framework disengagement are preferably used.But either《Seismic Design of Building is advised
Model (GB50011-2010)》、《Code for design of masonry strucres (GB50003-2011)》, still《Concrete Structures of Tall Building skill
Art code (JGJ3-2010)》, some structural specificationses have been merely given as, specific design method has not been provided and clearly applies
Work scheme.The traditional method of flexible connection is closely connected with pillar using wall, and wall typically reserves 150~200mm sky with beam
Gap, and tilt top block with building block and tamp.The wall of flexible connection mode can be caused to fill a drum for wall and held when earthquake occurs
Split, crack occurs in filling wall, not only influences its state of appearance, and bearing capacity can be caused low, and poor durability, reducing it makes
Use the life-span.

Embodiment
Prior art rigid connection structure is adjacent to frame column in filling wall and built by laying bricks or stones, is connected with beam by tiltedly building the mode of holding out against
Connect, this is current conventional way.Studied for a long period of time discovery through inventor, this connected mode there are following features：
(1) holes such as door, window can typically be opened up by filling in wall, and now filling wall can be as the transverse elasticity branch of Vierendeel girder
Seat, shortens the effective span of Vierendeel girder, Vierendeel girder is changed into short beam or deep beam.Under the effect of curved scissors repeatedly, diagonal crack is by edge
Beam total length extends, so that the ductility of beam and bearing capacity drastically decline, it is difficult to meet the shockproof requirements of " strong shear capacity and weak bending capacity ".
(2) in frame structure for the stress of frame column and damage -form, middle long column is generally belonged to, is occurred
Flexure type destroys.However, when adjacent intercolumniation opens up logical window in frame structure, because window skirt wall is made to the lateral confinement of frame column
With, significantly shorten the computed altitude of frame column, be allowed to be changed into short column, although specification to the hooping bars layout of short column with axial compression ratio strictly
Control, but because the anti-side rigidity of short column is big, the horizontal shear distributed in geological process is often difficult to meet that section is cut pressure ratio and wanted
Ask, failure by shear easily occurs, deformability is poor, reduces structural system ductility.
(3) in Practical Project, filling wall is directly built by laying bricks or stones on Vierendeel girder, is formed wall beam by curved combined member, is increased framework
Deflection of beam rigidity, the deformation of its sag, while the axial tension outside Vierendeel girder meeting commitment are substantially reduced, to Vierendeel girder pole
To be unfavorable, " strong column and weak beam " ductile yield mechanism of frame structure is difficult to be formed.
(4) characteristic that the filling flat in-plane stiffness of wall is big, shearing strength is low that is rigidly connected makes it in geological process midplane
Destroy seriously, if occurring that block caves in going out in-plane without reliable drawknot between filling wall and framework, trigger secondary disaster.
Filling the destruction of wall not only influences the use function of building, rehabilitation expense after more increase shake, and serious filling wall is broken
It is bad to influence normal emergency evacuation and threat to life safety.Pass through the investigation and analysis to Wenchuan earthquake earthquake in 2008, frame
The filling wall that is rigidly connected of frame structure destroys serious as first of anti-vibration defense lines.Substantial amounts of filling wall cracking, can make to people
Into huge psychological pressure, directly aggravation to the fear of earthquake, the filling wall that may collapse at any time to the life security of people also
Constitute a threat to.Under frequently occurred earthquake, even if after the filling wall destruction that is rigidly connected is not serious, but a large amount of minute cracks of metope are to shake
Repair brings great difficulty, and need to expend substantial amounts of human and material resources.In a word, the filling wall that is rigidly connected is difficult to meet now
Row earthquake resistant design code is to non-structural element requirements for fortification against earthquake.
In recent years, the traditional method of flexible connection is improved with reference to the suggestion of current specifications, some scholars.Than
Such as, (1) sets up constructional column：Reinforced concrete structural column is set at filling wall both ends, constructional column upper and lower ends respectively with Vierendeel girder
Connection, consider whether to need to set constructional column again among wall further according to length, the situation of punching of filling wall；(2) using laterally
Steel tie：On the basis of conventional flex connection, the post for filling wall and both sides is disengaged, reserves certain gap, and retained
Reinforcing bar in wall, the steel tie of intercolumniation or horizontal reinforcement band；(3) vertical and horizontal steel tie combination：Fill wall not only with
Frame column disengages, and is also disengaged with the Vierendeel girder in wall top portion, and in wall both sides, correspondence position builds by laying bricks or stones to form vertical small size groove,
Then place vertical reinforcement and horizontal steel tie, vertical reinforcement are connected with Vierendeel girder reserved steel bar；(4) constructional column and water are set up
Flat binder：Filling wall disengages when building by laying bricks or stones with Vierendeel girder, post, is connected using steel fastener with beam, post, when filling wall is too high,
Armored concrete linking beam is set in the horizontal direction, when filling wall is long, reinforced concrete structural column is set in vertical direction.
It is also big without specifically connection because current specifications does not have the concrete scheme and construction technology that provide flexible connection
Sample and standard collective drawingses, existing way are that a kind of of flexible connection traditional scheme is improved, generally will be in wall in these methods
Reinforced concrete structural column or horizontal binder are set in body, or steel tie is reserved in Vierendeel girder, post.In practice of construction
In, often there is the situation of filling wall displacement change so that the frame column or shear wall for originally having pre-buried steel tie are not applied
