Description
Technical field
The utility model belongs to the design and construction technique field of building industrialization, more particularly to a kind of assembled steel reinforced mixed
Solidifying soil shear wall.
Background technique
Building industrialization is the trend of current Building Trade in China development, is the weight for realizing the green building of " four sections, one environmental protection "
Want step.The important feature of building industrialization is exactly, and building element is prefabricated in the factory completion as far as possible, makes full use of the industry of factory
Change mechanical and complete information system management, the component being prefabricated in the factory is because of the standardization of its construction and the systematization of management, component
Quality tends to be guaranteed, and the grade of errors that can be realized construction industry marches toward " grade " by " Centimeter Level ".But due to
The limitation of transport capacity and hanging device, building structure as a whole must be split as one by one when being prefabricated in the factory
Component is transported to scene by automobile, in place by tower crane or lifting equipment.The connection of prefabricated components at the scene is that can structure sufficiently be sent out
Wave the key of its element bearing capacity.
Assembly of integral shearing wall structure or prefabricated integral frame-shear wall structure precast shear wall are existing at present
The connection of field, there are mainly two types of modes: (1) sleeve grouting connection, and shear wall is prefabricated to superimposed sheet bottom surface absolute altitude, and company is stretched out at top
Reinforcing bar is connect, after superimposed sheet concreting finishes and meets intensity, handling top shear wall precast section, top shear wall precast section
The pre-buried connection sleeve in bottom, lower part shear wall top connection reinforcing bar insertion top shear wall lower part connection sleeve in, it is complete
Cement injection base grouting material, grouting material have high-strength, early strong, ungauged regions and microdilatancy etc. substantially special in sleeve after complete in place
Property, co-operation can be effectively bonded together with connecting sleeve, connecting reinforcing bar.(2) slurry anchor overlap joint connection, with sleeve
The working principle connected of being in the milk is similar with construction procedure, except that in the lower part reserving hole channel of precast shear wall, in duct
Interior insertion connects reinforcing bar, and grouting material is then perfused in duct, and grouting material realizes connection reinforcing bar in duct after reaching intensity
Overlap joint.In addition there are also a kind of applications of overlaid plate type concrete shear wall also than wide, has provincial standard in certain provinces, folds
Plywood formula shear wall is that two sides concrete slab and steel bar girder are fabricated in factory and include Cavity structural member, after being transported to scene, in sky
Intracavitary embedded connection reinforcing bar and casting concrete ultimately form prefabricated and cast-in-place concrete entirety stress shear wall.
Sleeve grouting connection, its advantage is that quality of connection is reliable and stable, it is very widely used in the U.S. and Japan, and have
Nearly 40 years applicating histories.A large amount of experimental study is carried out to the technology of reinforced bar sleeve grouting connection both at home and abroad, using this
The building of item technology also experienced the test of multiple earthquake, the test including some violent earthquakes of Japan.Its disadvantage has following several
Point: (1) expense is more expensive, and connection sleeve price is higher, and the price of grouting material is also high, therefore increases assembled architecture
Construction cost is unfavorable for the popularization of building industrialization；(2) construction precision requires high, and top precast shear wall needs handle when in place
It is especially high to the positioning requirements of connection reinforcing bar and sleeve in the connection reinforcing bar insertion sleeve of lower part shear wall, once there is a company
It connects reinforcing bar and embedded sleeve barrel contraposition mismatches, integral shear wall just can not be in place；(3) the comparatively laborious complexity of construction procedure, connection
After reinforcing bar is inserted into sleeve, need to be perfused grouting material in sleeve, grouting material needs experimental examination its fluidity, expansion before use
The indexs such as rate, presetting period and final setting time, grouting material must construct within the specific time, require construction organization very high.
The advantage and disadvantage for starching anchor overlap joint connection are similar with sleeve grouting connection, and that eliminates connection sleeves, are changed to pre-buried ripple
Pipe, has saved part construction cost.Under normal circumstances, the caliber of bellows is bigger than the caliber for connecting sleeve, so slurry anchor overlap joint
The requirement connected to construction precision is also lower.But the reliability for starching anchor overlap joint connection does not have sleeve grouting connection high, in weight
The significant points of the structure or structure wanted preferentially use sleeve grouting connection.
The advantages of overlaid plate type concrete shear wall, is, without pre-buried connection sleeve or bellows, therefore to construction precision
It is required that, the concrete one of cast-in-place concrete and edge member and superimposed sheet top cavity in consistent with common cast-in-place concrete
It rises and pours, working procedure is simple, consistent with common cast-in-place concrete.The shortcomings that overlaid plate type concrete shear wall is two layers
Cavity size between precast slab is smaller, and when concreting can not effectively be vibrated, compactness it is difficult to ensure that,
Common solution is self-compacting concrete to be poured in cavity, but self-compacting concrete price is higher, is unfavorable for building industry
The popularization of change.Upper and lower layer overlaid plate type concrete shear wall is connected by the cast-in-place concrete in cavity with reinforcing bar, the size of cavity
Smaller, the strength and stiffness of junction are weaker, though there are many theory analysis and such connection type of verification experimental verification are " equivalent
It is cast-in-place ", but it is still necessary to undergo the inspection of earthquake even " big shake " for the safety and reliability of this connection type.
