Connecting structure of prefabricated block masonry type bearing wall and infill wall and connecting method

WANG FENGLAI

The invention provides a connecting structure of a prefabricated block masonry type bearing wall and an infill wall and a connecting method. The connecting structure comprises the prefabricated blockmasonry type bearing wall and the prefabricated block masonry type infill wall. A plurality of steel tie bars are uniformly distributed between the prefabricated block masonry type bearing wall and the prefabricated block masonry type infill wall, a connecting block is arranged between an end surface of the prefabricated block masonry type bearing wall and the end surface of the prefabricated block masonry type infill wall, the strength of the connecting block is lower than the strength of the prefabricated block masonry type infill wall, a stubble matched with the end part of the prefabricated block masonry type infill wall is arranged at one end of the connecting block, and a vertical plane structure fitting the end part of the prefabricated block masonry type bearing wall is arranged atthe other end of the connecting block. According to the connecting structure, the rigid connection of a using stage and the flexible connection of a preset failure surface under a large earthquake state are realized, so that the similarity of an actual stress state of the connecting position and a stress state of a calculation model is improved.

本发明提供了一种预制砌块砌体式承重墙与填充墙的连接结构及连接方法，连接结构包括预制砌块砌体承重墙和预制砌块砌体填充墙，预制砌块砌体承重墙和预制砌块砌体填充墙之间均布多个拉结钢筋，预制砌块砌体承重墙的端面和预制砌块砌体填充墙的端面之间设有连接块，连接块的强度低于预制砌块砌体填充墙的强度，连接块的一端设有与预制砌块砌体填充墙的端部配合的马牙槎，连接块的另一端为与预制砌块砌体承重墙的端部贴合的竖直平面结构。本发明实现了使用阶段的刚性连接和大震状态下预设破坏面的柔性连接，使连接位置的实际受力状态与计算模型受力状态的相似度提高。
