Construction and design method of staggered caulking type stone masonry wall reinforcing structure
The invention relates to a construction and design method of a staggered caulking type stone masonry wall reinforcing structure. The construction and design method comprises the steps that a groove with an X-shaped outline is chiseled in one side of a stone masonry wall along a mortar joint; polymer mortar is pressed and plastered into the groove; a plurality of L-shaped steel plates and T-shaped steel plates are embedded into the grooves filled with the polymer mortar in a staggered mode before initial setting of the polymer mortar, and the L-shaped steel plates and the T-shaped steel plates are arranged in a staggered mode to form a steel plate with an X-shaped outline; polymer mortar is smeared on one side of the stone masonry wall to form a polymer mortar surface layer, and the polymer mortar surface layer covers all the L-shaped steel plates and the T-shaped steel plates; by means of the L-shaped steel plates and the T-shaped steel plates embedded in the mortar joints of the stone masonry blocks, the purpose of effectively improving the overall lateral resistance of the stone masonry wall can be achieved. The embedded steel plate is beneficial to improving the defect of poor shear combination effect always existing between the stone block and mortar joint mortar; the through grooves formed in the outer sides of the steel plates are beneficial to enhancing the combination effect between the steel plates and the mortar surface layer on the outer side of the wall body, so that the stone masonry wall, the steel plates and the mortar surface layer organically form a stress whole; and an X-shaped staggered caulking reinforcement arrangement scheme constructed on the basis can further efficiently improve the overall lateral resistance of the stone masonry wall.
本发明涉及一种交错嵌缝式石砌体墙加固结构的施工及设计方法，包括在石砌体墙的一侧沿灰缝凿出“X”型轮廓的凹槽；将聚合物砂浆压抹入凹槽内；在聚合物砂浆初凝前把多个L形钢板和T形钢板交错嵌入由聚合物砂浆填充的凹槽中，多个L形钢板和T形钢板交错排列形成“X”型轮廓的钢板；在石砌体墙的一侧抹聚合物砂浆形成聚合物砂浆面层，聚合物砂浆面层覆盖所有的L形钢板和T形钢板；本发明借助嵌入石砌块灰缝中的L形钢板和T形钢板，可达到有效提高石砌体墙整体抗侧能力的目的。内嵌钢板有利于改善石砌块与灰缝砂浆之间一直存在的抗剪组合效应较差缺陷；钢板外侧开设的通槽有助于增强钢板与墙体外侧砂浆面层之间的组合效果，进而实现将石砌体墙、钢板与砂浆面层三者有机形成一个受力整体；在此基础上构建的“X”型交错嵌缝加固布置方案可进一步高效地提升石砌体墙的整体抗侧能力。
