and 8: skirting lines (8) are vertically laid at the upper wall corners of the vertical sound insulation sheets (6).
7. The construction method of the indoor EHS nanometer rubber-plastic heat-preservation sound-insulation structure according to claim 6, characterized in that: and 2, when the steel wire mesh (3) in the step 2 is fixed, two grids and three grids are used as fixing points, iron wires at the overlapped part are fixed at the foremost end of the upper layer, the iron wires at the fixing points are fixed and tied, the iron wire heads are wound and flattened, the wires are tied to 15-25 cm and tied to two sides, the two sides are folded in half when the steel wire mesh is fixed, the iron wire heads are parallel to the mesh, and the disconnection distance of the steel wire mesh (3) at the expansion joint is 1-2 cm.
8. The construction method of the indoor EHS nanometer rubber-plastic heat-preservation sound-insulation structure according to claim 6, characterized in that: and 6, covering and maintaining the exposed surface of the concrete by a plastic film, a plastic film and a gunny bag, and a plastic film and a straw curtain after calendering, and watering and maintaining after pouring is finished for 20 hours.
9. The construction method of the indoor EHS nano rubber-plastic heat-preservation and sound-insulation structure according to claim 6 or 8, characterized in that: the concrete is watered once every 2 hours, 2 times a day after 7 days, 20 days is a zero period, the concrete is watered after the exposed surface of the concrete is covered with a gunny bag or a straw mat, or directly watered, 3-4 times a day, 7-8 times when the environmental temperature is higher than 30 ℃, the surface of the concrete is ensured to be in a wet state, and the surface of the concrete is not extruded in the curing period.
