The assembled external thermal insulation cross-shaped composite wall with the lead pipe-coarse sand energy-dissipating and shock-absorbing key of the present invention is suitable for low and multi-storey buildings. The lead pipe-coarse sand energy-dissipating and shock-absorbing key, EPS thermal insulation module, and its assembled light-weight wall panels are factory-produced, and assembled on-site to form a lightweight thermal-insulation, anti-seismic, and energy-saving integrated wall, with high production efficiency and good quality.

(2) Utilize recycled concrete, an environmentally friendly building material with a large amount and a wide range, which saves resources and is conducive to sustainable development.

(3) Integration of heat preservation, earthquake resistance, energy saving and fire prevention. The outer insulation layer of the lightweight wall of the present invention is an EPS module, and the inner side is a recycled concrete wallboard, which is lighter in weight than a solid concrete wall and better in seismic performance than a brick wall. The EPS thermal insulation module is used as the external thermal insulation layer of the lightweight wall, which can significantly improve the thermal insulation effect of the wall.

The force stiffness decreases and the structural period becomes longer. After the period becomes longer, the seismic action decreases correspondingly, but the horizontal lateral movement of the wall is relatively large. At this time, the lead pipe-coarse sand energy dissipation and shock absorption key begins to play an important role. 1. The role of the displacement development of the lower assembled wallboard. The second is the energy dissipation and shock absorption under repeated horizontal earthquakes. The lead pipe mainly dissipates energy and shock through plastic deformation, and the coarse sand mainly dissipates energy and shock through friction.

(6) Easy to transport and install. The prefabricated components adopted by the invention are light in weight and convenient in transportation and installation.

(7) Significantly reduce the wetness of pouring concrete on the construction site, reduce the time required for concrete on-site maintenance, and speed up the construction progress. Adopting the assembled external thermal insulation cross-shaped composite wall with lead pipe-coarse sand energy dissipation and shock-absorbing keys proposed by the present invention reduces formwork projects, concrete cast-in-place projects, etc., saves resources, saves labor, reduces management costs, and ensures project quality.
