Description

A kind of the strong ties construction and construction method of assembled vertical member and basis
Technical field
The present invention relates to the strong ties constructions and construction method of a kind of assembled vertical member and basis.
Background technology
Prefabricated assembling type reinforced concrete structure the developed countries such as America and Europe, Japan had more practical application and More mature technical research.In recent years, national development green building greatly develops assembled architecture, promotes construction industry transition Upgrading.With the quickening of China " building industrialization, housing industrialization " process, the application of fabricated construction building is increasingly extensive, The practical application and theoretical research that the country builds fabricated construction deepen continuously.
Rarely occurred earthquake act on force effect under, in conventional cast-in-place concrete frame structure, bottom vertical member basal cross section by Power is maximum, tension side concrete cracking, and tension reinforcement can take the lead in entering plastic strain stage, the steel in certain length at this Muscle generates plastic deformation, forms plastic hinge, with the increasing of load, column bottom tension side concrete further cracks, tension steel Muscle strain further increases, and plastic hinge deformation further increases, and strains and then is pulled off until tension reinforcement reaches capacity, structure It destroys.This destruction is that have apparent destruction sign before structure destruction in the apparent deformation of structure generation, can be striven to user Certain escape time is taken, is referred to as " ductile fracture ".The key that above-mentioned ductile fracture is formed is connecting node plastic hinge It is formed.Two necessary conditions for forming plastic hinge are that column bottom steel bar stress enters plastic strain stress stage and structure for plastic hinge Certain length is provided and forms plastic deformation.
The common joint reinforcing bar connection type of assembled arthitecutral structure is sleeve grouting connection at present.Bottom prefabricated post with it is existing When casting foundation reinforcing bar is using sleeve grouting connection, sleeve is often embedded in bottom prefabricated post, is vertically connected with bar diameter by pre- Structure compound action loadometer, which is calculated, at column basal cross section processed carries out value, connects reinforcing bar at this time and usually takes same diameter, connects in this way It is safe in frequently occurred earthquake force effect lower structure.But under rarely occurred earthquake force effect, column bottom tension reinforcement enters plasticity and answers After change, since grout sleeve is also in elastic stage, tension reinforcement can not be coordinated to generate plastic deformation, i.e., can not be tension steel Muscle provides enough deformation lengths.In this case, when active force continues to increase, tension reinforcement is not obviously deforming In the case of stress constantly increase, until its stress reaches its ultimate tensible strength angle value to being broken suddenly.It is this to have no sign Failure mode be referred to as " brittle break ", be do not allow in structure design occur failure mode.

The present disclosure applies equally to precast concrete shear wall structure and frame shear wall structures, i.e.,:Armored concrete is pre- Vertical member 2 processed is prefabricated reinforced concrete shear wall.
The invention also discloses the strong ties construction methods of a kind of assembled vertical member and basis, including:
Step 1: in factory, armored concrete Prefabricated vertical member 2 is prepared, armored concrete Prefabricated vertical member 2 is pre-buried There is quantity to correspond to the grout sleeve 3 of its vertical muscle 21, each grout sleeve 3 is embedded in armored concrete Prefabricated vertical member 2 Concrete in, and the lower connectivity port 3b of grout sleeve 3 armored concrete Prefabricated vertical member 2 lower face expose, fill The grouting port 3c and thick liquid discharge mouth 3d for starching sleeve 3 expose in the side wall of armored concrete Prefabricated vertical member 2, and armored concrete is pre- The lower end of each vertical muscle 21 of vertical member 2 processed is installed in the upper connectivity port 3a of corresponding grout sleeve 3;
Step 2: at the construction field (site), the reinforcement foundation 12 and protruding bar 11 on binding cast-in-situ steel reinforced concrete basis 1, In, protruding bar 11 corresponds to armored concrete for connecting armored concrete Prefabricated vertical member 2, the quantity of protruding bar 11 The vertical muscle 21 of Prefabricated vertical member 2, also, diameter of the diameter of each protruding bar 11 than corresponding vertical muscle 21 is big;
Step 3: pouring the concrete on cast-in-situ steel reinforced concrete basis 1 so that bury the lower part of each protruding bar 11 In the concrete on cast-in-situ steel reinforced concrete basis 1, the upper end of each protruding bar 11 is from cast-in-situ steel reinforced concrete base The concrete upper end of plinth 1 is stretched out upwardly, to form cast-in-situ steel reinforced concrete basis 1, wherein cast-in-situ steel reinforced concrete basis 1 Can be shallow foundation can also be pile foundation;
Step 4: after the concrete on cast-in-situ steel reinforced concrete basis 1 reaches sufficient intensity, lifting armored concrete is prefabricated Vertical member 2 so that the upper end of each protruding bar 11 is inserted into the lower connectivity port 3b of corresponding grout sleeve 3, and The verticality of armored concrete Prefabricated vertical member 2 is adjusted, also, by armored concrete Prefabricated vertical member 2 and now Pour and be laid with the usual ways such as cushion block between reinforced concrete foundation 1, make the lower face of armored concrete Prefabricated vertical member 2 with it is existing It pours between the concrete upper surface of reinforced concrete foundation 1 there are gap, the thickness in the gap is by being defined as 20mm;
Step 5: grouting material is perfused to grout sleeve 3 so that each protruding bar 11 passes through a grout sleeve 3 It is connected with corresponding vertical muscle 21;
Step 6: after whole grout sleeves 3 complete grouting material perfusion, grouting material is perfused into gap, and smooth out reinforcing bar Joint face between concrete prefabricated vertical member 2 and cast-in-situ steel reinforced concrete basis 1 sits pulp layer 4 to form concrete;It waits for complete After portion's grouting material reaches sufficient intensity, that is, complete armored concrete Prefabricated vertical member 2 and cast-in-situ steel reinforced concrete basis 1 Between strong ties.
To which strong ties construction method of the invention can realize that cast-in-situ steel reinforced concrete basis 1 is pre- with armored concrete The strong ties of connecting node between vertical member 2 processed, and the equal mature and reliable of each step of the construction method so that whole Construction efficiency is high, construction quality can be guaranteed.
Wherein, in order to ensure grout sleeve 3 can play reliable connection function, in above-mentioned steps five, to grout sleeve 3 Perfusion grouting material mode be:By grouting material from the grouting port 3c injections of grout sleeve 3, wait that the grouting material injected is covered from grouting After the thick liquid discharge mouth 3d of cylinder 3 overflows, then timely plugging grouting sleeve 3 grouting port 3c and thick liquid discharge mouth 3d, to complete to grout sleeve 3 Grouting material perfusion.
In addition, the strong ties construction method of the present invention, can equally use above-mentioned assembled vertical member with it is basic strong The preferred structure of connecting structure.
The present invention is not limited to above-mentioned specific implementation mode, according to the above, according to the ordinary technical knowledge of this field And customary means, under the premise of not departing from above-mentioned basic fundamental thought of the invention, the present invention can also make other diversified forms Equivalent modifications, replacement or change, all fall among protection scope of the present invention.
