AI Technical Summary

Technical Problem

The prior art is difficult to reduce the cost of reinforced stone walls while ensuring seismic resistance, especially when there are many gray joints on stone walls and different widths and depths.

Method used

The negative Poisson's material layer and cement matrix composite material layer are successively filled in the skeleton ash joints of the stone wall from the inside to the outside, and cement mortar or fine stone concrete layer are filled in the general ash joints. Through this filling method, the seismic resistance of the wall is improved and the cost is reduced.

Benefits of technology

By using high-performance negative Poisson's ratio material layer and cement-based composite material layer in the skeleton ash joints, seismic energy can be effectively consumed and the strength and elastic deformation ability of the wall can be improved. Only high-performance materials are used in the skeleton ash joints, and the use of cheaper materials in the general skeleton ash joints reduces the overall cost.
