The embodiment is different from the traditional connection mode that the bottom mortar layer is the weak point of the structure, the integrity is enhanced by adding the reinforcing steel bars for post-pouring, the weak point is transferred, the shear-resistant post-pouring part can be destroyed in batches through the composite wall filling building blocks, the composite wall rib beams and the composite wall rib columns, the multi-stage energy consumption effect is achieved, the bearing capacity of the structure is fully exerted, and the anti-seismic performance of the structure is enhanced.
The concrete connection method is different from the traditional connection method that the mortar bed is not firmly contacted with concrete, is easy to damage in the construction process, and cannot detect the compactness; in the embodiment, the post-cast strip layer is protected in the wall body, the grouting compactness can be detected through the position of the wall gap, the bearing capacity is ensured, a natural structural waterproof barrier is formed, and the later waterproof pressure is greatly relieved; the cost is lower, the process is simple, the requirements on the production and installation precision of the component are not high, and the operation requirements on field workers are lower.
The above-described embodiment is only one of the embodiments that can implement the technical solution of the present invention, and the scope of the present invention is not limited by the embodiment, but includes any variations, substitutions and other embodiments that can be easily conceived by those skilled in the art within the technical scope of the present invention disclosed.
