English to Russian Tech/Engineering Construction / Civil Engineering стеновой блок из пенополистиролбетона

The heat-insulated soundproof concrete load-bearing shear wall with steel wire net-cages, which is characterized in that the wall comprises a polystyrene foam board, both sides of which are respectively provided with a steel wire net-cage which forms the wall framework, set forth in patent description No. CN201137225, is of the same technical level. This known solution is deficient in that the steel loses its temper at 400-500°C and can resist fire for up to 30 minutes since the steel wire net-cage is not protected with a fire retardant material. Another deficiency of this solution is that the use of a steel wire net-cage does not allow the fastening of heavier objects into the wall.

ну с load bearing понятно, "несущая стена. а вот shear?
