Sandwich heat insulation reinforced concrete shear wall and construction method thereof

Abstract

The invention discloses a sandwich heat insulation reinforced concrete shear wall and a construction method thereof, belonging to the technical field of heat insulation walls and construction methods. The sandwich heat insulation reinforced concrete shear wall is characterized in that a first fixing mesh and a first vibration strengthening mesh are sequentially arranged in parallel at the outer side of a first heat insulation layer at intervals; a first connecting drawing wire is arranged in the first heat insulation layer, the inner end of the first connecting drawing wire is inserted into abearing wall body, and the outer end of the first connecting drawing wire is fixed with the first fixing mesh and the first vibration strengthening mesh; and a first outer template jack screw penetrating through a first outer protective layer is connected between the first fixing mesh and the first vibration strengthening mesh. When concrete is poured, a heat insulation screen plate and a template are subjected to an interconversion principle of a point load and an area load, the inner-side concrete and the protective layer are constructed respectively and independently, therefore, the process is simple, the quality is guaranteed, the construction speed is accelerated, a heat insulation layer and a main structure are completed at the same time, the construction period time of outer walls is shortened, the fireproof effect is remarkable, the problems, such as cracking and falling of the outer heat insulation layer of the outer walls, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation walls and construction methods, and in particular relates to sandwich thermal insulation reinforced concrete shear walls and construction methods. Background technique [0002] At present, in the engineering shear wall structure of buildings, the external wall insulation technology mainly adopts the following two technologies: first, most of them are connected to the wall by sticking nails, and the surface is covered with a 3-6mm thick mortar protection layer. Practice has proved that the thermal insulation layer and protective layer in this technology are affected by natural environments such as wind, sun, rain and so on. Cracking and shedding generally occur within a short period of use, which affects the insulation effect and service life. The insulation layer is mostly made of polystyrene board, which is a flammable material. It is exposed for a long time during the construction pe...

Cracking and shedding generally occur in a short period of use, which affects the insulation effect and service life

The insulation layer is mostly made of polystyrene board, which is a flammable material. It is exposed for a long time during the construction period, and the protection is thin. It is vulnerable to damage and leaks for a long time. It is easy to cause a fire when exposed to an open flame. Fires in buildings in other places are all fire accidents caused by igniting the external wall insulation, resulting in significant personal and property losses; second, sandwich insulation technology is used, but the process is complicated, the construction is difficult, and the quality of the project cannot be guaranteed.
