Hole opening reinforcing device for reinforcing masonry structure wall after hole opening

The utility model relates to a hole reinforcing device for reinforcing a masonry structure wall after punching, two longitudinal perforated plates are opposite to each other and are respectively and vertically welded on an end plate, and the distance between the two longitudinal perforated plates is matched with the wall. And the hole reinforcing device is embedded into the wall body and is fixed with the wall body through a split bolt. The hole reinforcing device is simple in structure, easy to construct and reasonable in transverse and longitudinal stress, and the overall stress performance of the edge of the hole and the whole wall can be enhanced. Meanwhile, the occupied hole size can be reduced, the space occupied by the reinforcing component of the hole after the hole is formed in the wall surface is reduced, and the space utilization rate is increased. 本实用新型涉及一种用于砌体结构墙体开洞后加固的洞口加固装置，其中，两纵向开孔板正相对并分别垂直焊接在端头板上，两纵向开孔板间距与墙体相适配。洞口加固装置嵌入墙体并通过对拉螺栓与墙体固定。本实用新型的洞口加固装置结构简单，易于施工，其横纵向受力合理，可增强洞口边缘与整个墙体的整体受力性能。同时，还可减少占
