Structure, is characterized in that, the bore dia of reserving hole is more than equivalence bar diameter, to ensure perfusion foot in hole
Enough microdilatancy mortars so that it is effective bonding equivalence reinforcing bar and aperture wall.
6. use the assembly concrete frame-shear structure Shear-wall Connecting Beam Used in any of the one of claim 1 to 5
The frame shear wall structure thing of assembled attachment structure.
7. an assembled method of attachment for assembly concrete frame-shear structure Shear-wall Connecting Beam Used, is characterized in that, including
Following steps:
The first step, selects the overall diameter pore-forming steel pipe more than equivalence bar diameter, at pore-forming steel pipe walls winding screw
Stirrup, is then embedded in prefabricated coupling beam, dry wall or prefabricated band Liang Qiang in advance even by the pore-forming steel pipe being tied with tie hoop
The precalculated position of beam；
Second step, pours prefabricated coupling beam, dry wall or prefabricated band Liang Qiang, after concrete just solidifies, extracts
Pore-forming steel pipe, forms prefabricated coupling beam, dry wall or the prefabricated band leaving tie hoop around band hole and hole
Liang Qiang；
3rd step, prefabricated coupling beam and the splicing of dry wall, put into the hole of prefabricated coupling beam by equivalence reinforcing bar, will be pre-
The hole para-position of coupling beam processed and dry wall, leaves grouting seam between prefabricated coupling beam beam-ends and dry wall, after para-position completes,
Equivalence reinforcing bar is extracted, and stretches in corresponding dry wall in reserving hole, then layout U around grouting seam
Section mould plate, by glass cement around U-shaped template, seals with prefabricated coupling beam and dry wall；
The joining method of prefabricated band beam wall coupling beam and prefabricated band beam wall coupling beam and prefabricated coupling beam and the splicing side of dry wall
Method is identical；
4th step, simultaneously from prefabricated coupling beam and dry wall, or in the Grouting Pipe of prefabricated band Liang Qiang both sides, perfusion is micro-swollen
Buckle is starched, until microdilatancy mortar is full of reserving hole and the U-shaped template of grouting seam of prefabricated components；
5th step, after microdilatancy mortar solidifies, removes U-shaped template, completes prefabricated coupling beam and dry wall or pre-
Band Liang Qiang processed and the splicing of prefabricated band Liang Qiang；
Repeat above-mentioned five steps, complete the assembled connection of assembly concrete Shear Wall in Frame-Shear Wall Structures coupling beam.
8. according to the assembled connection side of the assembly concrete frame-shear structure Shear-wall Connecting Beam Used described in claim 7
Method, is characterized in that, is carrying out the splicing of prefabricated coupling beam and dry wall or prefabricated band Liang Qiang and the spelling of prefabricated band Liang Qiang
When connecing, the three to four described step first equivalence reinforcing bar is put into prefabricated coupling beam or prefabricated band Liang Qiang hole,
And reserve the termination not less than 2cm at nose end, then by the hole para-position of prefabricated coupling beam and dry wall, prefabricated company
Leave grouting seam between beam beam-ends and dry wall, after para-position completes, equivalence reinforcing bar is extracted, and stretch into the pre-of correspondence
In the reserving hole of wall processed or prefabricated band Liang Qiang, then arrange around grouting seam U-shaped template, U-shaped template week
Enclose by glass cement, seal, finally at hole and U with the coupling beam of prefabricated coupling beam and dry wall or prefabricated band Liang Qiang
Perfusion microdilatancy mortar in section mould plate.
