New and old wall body connected through newly-built concrete combed joint and construction method of new and old wall body
The invention relates to a new and old wall connected through newly-built concrete combed joints and a construction method of the new and old wall, and belongs to the technical field of seismic reinforcement. Comprising a concrete combed joint, a combed joint bottom platform, a combed joint boss, a newly built inner partition wall, a U-shaped rib I, a U-shaped rib II and a through rib, the concrete combed joint is C25 fine aggregate concrete and is composed of a combed joint bottom platform and a combed joint boss; the newly built inner partition wall is of a masonry structure; the two through ribs are arranged in the center of the whole length of the combed joint bottom platform; the U-shaped rib I wraps the two through ribs, and the end part of the U-shaped rib I is implanted into a rib embedding hole of the original longitudinal wall; the two through ribs are wrapped by the U-shaped rib II, and the end parts of the U-shaped rib II extend out of the combed joint bottom platform in parallel and are prepared to be in lap joint with a newly built inner partition wall; and the U-shaped rib I, the U-shaped rib II and the through rib are bound together and are integrally poured. The invention mainly aims to improve the overall shock resistance of the original longitudinal wall and the newly built inner partition wall, and jointly bear the earthquake action, thereby enhancing the toughness of the house.
本发明涉及一种采用新砌混凝土马牙槎连接新旧墙体及其施工方法，属于抗震加固技术领域。包括混凝土马牙槎、马牙槎底台、马牙槎凸台、新砌内隔墙、U型筋I、U型筋II、通筋；所述的混凝土马牙槎为C25细石混凝土，由马牙槎底台、马牙槎凸台构成；所述的新砌内隔墙为砌体结构；所述的通筋延马牙槎底台通长居中布置两根；所述的U型筋I将两根通筋包裹在内，端部植入原纵墙的植筋孔中；所述的U型筋II将两根通筋包裹在内，端部平行伸出马牙槎底台外，准备与新砌内隔墙搭接；所述的U型筋I、U型筋II和通筋绑扎在一起，进行整体浇筑。本发明主要是为了提高原纵墙与新砌内隔墙的整体抗震能力，共同承担地震作用，从而增强房屋的韧性。
