在建筑物抗震加固工程中,常采用钢筋混凝土构造柱和圈梁。按民用建筑抗震加固图集要求,每隔100～200cm用钢筋混凝土销键与原有砌体锚固,以增强建筑物的整体性,销键还要承担部分圈梁自重。但使用销键需在原建筑物上手工剔凿孔洞,劳动强度大;剔凿时对建筑物损伤大,影响其整体性;圈梁一般设在同一标高,如每隔100200cm凿一销键孔,将使外墙形成一个水平的创伤面,对抗震不利;凿打孔洞还会给生
In the seismic strengthening of buildings, reinforced concrete structural columns and ring beams are often used. According to the requirements of the atlas of seismic reinforcement of civil buildings, every 100 to 200 cm is anchored with reinforced concrete pins and original masonry to enhance the integrity of the building. However, the use of pin keys must be hand-picked holes in the original building, the labor intensity; remove the building damage, affect the integrity; ring beam is generally set at the same elevation, such as every 100200cm chisel a key hole, Will form a horizontal wound surface on the exterior wall, which will be detrimental to the earthquake; it will give birth to the hole
