Decorative thermal insulation guard bearing integrated dense rib composite prefabricated exterior wall plate and preparation method thereof

Abstract

The invention discloses a decorative thermal insulation guard bearing integrated dense rib composite prefabricated exterior wall plate. The exterior wall plate comprises a surface layer, a thermal insulation block layer is bonded to the inner side of the surface layer, the thermal insulation block layer is laid to form a grid structure, a glass fiber mesh cloth, heat insulation strips, rib beams and rib columns are orderly arranged between grids and around the thermal insulation block layer from bottom to top, the glass fiber mesh cloth is bonded to the surface layer, the heat insulation strips are laid on the glass fiber mesh cloth, pass through the glass fiber mesh cloth and are bonded to the surface later, the glass fiber mesh cloth coats the outer sides of the heat insulation strips, two sides of the glass fiber mesh cloth respectively wind bottom longitudinal bars of reinforcing bars of the rib beams and rib columns and are fixed through iron wire colligation, the rib beams and rib columns have reinforced concrete structures and are casted to the heat insulation strips, and the inner side surfaces of the rib beams and rib columns align at the inner sides of the thermal insulation block layer. The invention also discloses a preparation method of the exterior wall plate. The exterior wall plate has a simple structure, a compact inner structure and good heat preservation performances.

Description

technical field [0001] The invention relates to a composite prefabricated exterior wall panel with dense ribs, in particular to a composite prefabricated exterior wall panel with dense ribs integrated for decoration, heat preservation, enclosure and load-bearing and a manufacturing method thereof. Background technique [0002] With the rapid development of my country's construction industry, the rational use of building resources cannot be ignored. In terms of energy consumption, building energy consumption accounts for 25% to 27% of my country's total energy consumption, and energy consumption caused by building exterior walls accounts for 25% to 27% of the total building energy consumption. Therefore, the good thermal insulation performance of building walls is the core to realize building energy saving. Realize the integration of wall insulation and structure, ensure the same life span of insulation and buildings, and promote the innovation of new wall materials and the pa...

AI Technical Summary

Problems solved by technology

The existing sandwich dense rib thermal insulation composite wall achieves the thermal insulation effect by sandwiching high-efficiency thermal insulation materials between the inner and outer leaf walls, but it mostly relies on actual experience and existing production processes, the structure is complex and not conducive to energy conservation and environmental protection, and its fire resistance and durability are poor; The internal structure cannot be effectively connected closely, and the compression resistance is weak

In particular, the outer protective wall is mainly built by hand, with a low degree of industrialization and takes up a lot of resources.

The traditional external wall insulation adopts reinforced concrete structure or bricks, which is expensive to manufacture, time-consuming and labor-intensive, and has a long production cycle.
