4, constructional column and frame column (or shear wall) have a hole of distance 20mm, and with elastic material (rock wool, foamed glue Deng) tamp, it is ensured that the flexible connection of filling wall and main structure can't bring adverse effect to main structure, realize rule The flexible connection requirement of model.

5, in the spacing of the two sides vertically about 500mm of filling wall by limit angle steel and iron parts anchor in frame column or shear wall On, the lateral confinement of filling wall plane outer displacement is become, is conducive to resistance filling wall and collapses outside the plane under geological process.

6. antidetonation steel tie within the walls is not led deeply since filling wall and frame column (or shear wall) have the gap of 20mm In body structure, it is ensured that the level for filling wall is unfettered with vertical deformation, is conducive to the Crack Control Design for filling wall.

After 7. limit angle steel and iron parts are fixed with thin layer putty by ironware be sealed to filling one horizontal plane of wall, do The decorative effect of ironware is not appeared to metope.

8. the utility model had both met national standard " seismic design provision in building code " the 3.7.4 articles " frame knot of GB 50011 The filling wall of structure is considered as its setting to the adverse effect of earthquake-resistant structure, avoids irrational setting and lead to the broken of main structure It is bad " regulation, realize the flexible connection of wall and main structure, and meet national standard " Code for design of masonry strucres " GB The regulation of 50003 the 6.3.4 articles " constructional column should be arranged in filling wall end ", while meeting that " filling wall end structure column is away from frame The gap not less than 20mm should be reserved between column " regulation.

9. and main structure enables filling wall detached at a distance of the wall end of 20mm setting constructional column, and constructional column makes to fill Steel tie within the walls has reliable anchoring at wall end, the particularly important is this configuration make wall plane outer displacement by To the limitation of limit angle member, this flexible connection mode can also allow to fill wall since wall caused by being self-possessed is crept not by about Beam, adapts to the vertical deformation of wall, so that the crack for preventing wall and frame column junction occurs.
