The utility model relates to an expanded and vitrified small ball insulation non-dismantling formwork which is suitable for building exterior wall external insulation and a concrete placement non-dismantling formwork with a concrete beam, a concrete column and a concrete shear wall adopted. The expanded and vitrified small ball insulation non-dismantling formwork is provided with an expanded and vitrified small ball insulation plate. A first alkali-resistant glass fiber mesh layer and a second alkali-resistant glass fiber mesh layer are arranged in the expanded and vitrified small ball insulation plate. A plurality of rectangular grooves are arranged in the back portion of the expanded and vitrified small ball insulation plate so that the expanded and vitrified small ball insulation plate can be conveniently combined with concrete into a whole in the process of concrete placement. The expanded and vitrified small ball insulation non-dismantling formwork is reasonable in design. The expanded and vitrified small ball insulation non-dismantling formwork is used as the concrete placement non-dismantling formwork with the concrete beam, the concrete column and the concrete shear wall adopted, insufficient parts of self-insulation systems of the concrete beam, the concrete column and the concrete shear wall can be solved, cold-heat bridging and energy-saving and insulation blank spots are avoided, and gapless energy saving and insulation of buildings can be truly achieved.
