Fabricated heat preservation decoration and structure integration wall and preparing and installing technology thereof

Abstract

The invention relates to a fabricated heat preservation decoration and structure integration wall and a preparing and installing technology thereof. The fabricated heat preservation decoration and structure integration wall comprises a bearing skeleton and a gradual change composite heat preservation layer in pouring fixed connection with the bearing skeleton, and the gradual change composite heatpreservation layer comprises a micropore foam concrete base layer, a heat preservation core material layer and an inorganic heat preservation material gradual change transition layer which are sequentially arranged. The side face of the inorganic heat preservation material gradual change transition layer is provided with an outer decorative panel protective layer fixedly connected with the bearing skeleton. The bearing skeleton and the gradual change composite heat preservation layer jointly form a prefabricated composite outer wall panel, the bearing skeleton is adopted as the skeleton structure for bearing various load effects, and the anti-seismic and wind resistance structure performance of the wall panel is enhanced; the gradual change composite heat preservation layer overcomes thedefects of surface layer material cracking, leakage and large deformation caused by large internal and external temperature differences, and a building exterior wall integrating facade decoration, fire prevention, heat preservation, heat insulation and structure safety is formed.

Description

technical field [0001] The invention relates to the field of architectural technology, in particular to an assembled wall with thermal insulation decoration and structure integration and its preparation and installation process. Background technique [0002] To promote the adjustment and upgrading of industrial structure, the State Council issued the "Guiding Opinions on Vigorously Developing Prefabricated Buildings" in February 2016, requiring all provinces and cities to develop prefabricated buildings such as prefabricated concrete structures, steel structures and modern wooden structures according to local conditions, and improve construction engineering standards and Quality, a series of policies have been introduced in various places to support it. At present, exterior wall panels, interior wall panels, laminated floors, balcony panels, air-conditioning panels, stair panels, prefabricated beams, prefabricated columns, etc. are widely used for prefabricated components.

AI Technical Summary

Problems solved by technology

The main manifestations are: (1) Autoclaved aerated concrete slabs (ALC slabs) are currently the most widely used non-load-bearing assembled exterior walls. It is also difficult to overcome the adverse effects of thermal bridge parts of the thermal insulation technology inside the external wall and the phenomena of moisture resistance and condensation caused by the insulation layer falling off, hollowing, and peeling caused by the insulation technology.

(2) The base layer adopts the composite wall construction technology of prefabricated wall panels and secondary construction of the insulation layer, which does not conform to the development direction of the prefabricated external wall construction at the present stage, and reduces the construction efficiency and the quality of the building external wall

(3) The base layer adopts the composite wall insulation technology of prefabricated wall panels and secondary construction of the insulation layer, which cannot realize the same service life of building insulation and prefabricated wall panels. Requirements for simultaneous design, simultaneous construction and simultaneous acceptance of thermal insulation walls
