With the increasing national economy and the continuous improvement of the construction technical level, the house safety is more and more concerned by people, and the requirement of the standards and regulations on the earthquake resistance of non-structural members is also improved. After a disaster occurs, the damage of the non-structural part directly or indirectly causes huge economic property loss amount, the damage rate is relatively high, and the damage of part of components can influence the smooth operation of personnel escape and rescue work.

The infilled wall is an indispensable part of a house for performing its intended functions, and plays an important role in the division and functional partitioning of rooms. When a disaster occurs, the filler wall is often cracked or even collapsed due to the fact that the filler wall is not reliably connected with a main body structure and the material density is high or the integrity of the wall body is not high. In order to strengthen the connection between the filler wall and the main body structure and strengthen the integrity of the filler wall and the main body structure, the technical scheme that the connecting ribs can be quickly spliced and embedded between the filler wall and the masonry wall is provided, the damage degree of the wall body caused by disasters can be weakened, meanwhile, the building construction efficiency can be improved, and the construction cost is reduced.

At present, the setting method of the tie bar mainly comprises two methods: firstly, a bar planting method, namely, after the poured concrete column meets the strength requirement, punching a hole at the corresponding position of the column, injecting a chemical adhesive after cleaning the hole, and rotationally planting a reinforcing bar; and the other is a partial pre-embedding method, namely binding partial tie bars on the frame column steel bars according to the designed length, and bending the tie bars by 90 degrees at the inner wall of the frame column template for reserved welding. And after the concrete pouring is finished and the template is removed, chiseling the frame column to expose the bent tie bars, and then welding the tie bars with the rest reinforcing steel bars.
