Description
Technical field
The invention belongs to technical field of buildings, particularly relate to flexible connecting device and the building method thereof of a kind of masonry filler wall and main body frame.
Background technology
Frame wall filled with masonry is rigidly connected measures such as being primarily referred to as the intensity taking to increase component or the connection that increases between component, by improving the performances such as the globality of structure, resists the impact of earthquake. Its maximum drawback is in that: the patch of post and infilled wall is built, and from local, the Stiffness Distribution changing frame structure or rigidity sudden change, formation weak floor, change the deformation form of corresponding pillar; In geological process, rigidly connected infilled wall autoclasia is serious, the theme component of structure and the overall performance of structural system is adversely affected simultaneously.
When adopting the method disengaged, infilled wall two ends and frame column, between infilled wall end face and Vierendeel girder, reserve the gap being not less than 20mm. Infilled wall two ends should snap in and be located at the bottom of beam, plate and in the bayonet socket ironware of post side, and the wall side vertical spacing of card oralia is not preferably greater than 500mm. The Out-Plane Stability Problems of infilled wall during disengagement mode is so adopted less to disengage mode more prominent.
The method of attachment not disengaged is adopted to there is also problems. Current frame wall filled with masonry tension rib construction technology is mostly based on bar planting method. The problems such as tension rib chemically-planted steel bar method problem appear to is that the reinforcing bar of implantation is insecure, and the durability of Chemical Felter is unstable, and bar planting method also can not solve to build by laying bricks or stones after settle the tension rib caused and produce additional stress problem with wall connecting place. These problems have a strong impact on structural safety, reduce the anti-seismic performance of structure, leave security-hidden trouble to engineering. The tension rib of GB50011-2010 " seismic design provision in building code " regulation infilled wall should reserve from frame concrete post, but tension rib is embedded in frame column, the error built by laying bricks or stones due to practice of construction and the modulus difference of building block make pre-buried tension rib often not corresponding with the position of horizontal mortar joint, having to, it is curved artificially to be changed by tension rib, changing its Path of Force Transfer and stress performance, the effect so reducing tension rib also reduces the stress performance of structure.Secondly, masonry mortar elastic modelling quantity is relatively low, causes the sedimentation after building by laying bricks or stones so that tension rib produces additional stress effect with wall connecting place.
For overcoming rigidly connected drawback, " the masonry filler wall detail of construction " 10SG64-2 proposes and between infilled wall and agent structure, flexibly connects scheme, " seismic design provision in building code " (GB50011 2011) the 13.2.1 article regulation: to the building element flexibly connected, rigidity can be not counted in, the masonry filler wall stiffness contribution to agent structure can be left out. Therefore, reduction coefficient natural vibration period of agent structure can be considered when agent structure seismic resistance calculation, facilitate the design application of xoncrete structure. But, there is no effective flexible connection forms at present and can solve masonry filler wall to the stiffness contribution of agent structure, masonry filler wall sedimentation and deformation to problems such as the impacts of tension rib.
