Lightweight cellular concrete composite large plate with functions of decoration, bearing and heat preservation, and production method thereof

Abstract

The invention provides a lightweight cellular concrete composite large plate with functions of decoration, bearing and heat preservation, and a production method thereof. The composite large plate isprovided with a decorative concrete surface layer, a reinforced common concrete bearing layer and a cellular concrete heat insulating layer in sequence from outside to inside. According to the composite large plate, decoration, bearing, energy conservation, and durability are integrated with industrialized production and construction, and good mechanical properties, thermal performance, decorationand durability are achieved. During construction, a complex process that an ordinary concrete external wall needs on-site wet operation to be used as an external heat preservation layer is omitted, the surface of a wall plate has natural and plain decorative textures, the reinforced concrete layer has the bearing function, and the cellular concrete layer has the lightweight, heat preservation andheat insulating functions. Combination of a wall energy-saving technology and building industrialization is achieved, and the lightweight cellular concrete composite large plate shows very broad market prospects and application value in the current process of building intelligent cities and green cities.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a lightweight microporous concrete composite slab with functions of decoration, bearing and heat preservation and a production method thereof. Background technique [0002] In recent years, my country has entered a new stage of construction industrialization and the construction of green cities and smart cities, but there is a lack of new materials and technologies that meet the requirements of this era. [0003] How to combine building energy conservation with building industrialization is the primary issue we are facing at this stage. In terms of the production of large external wall slabs for building industrialization in my country, a "sandwich" structure in which a layer of polystyrene board is sandwiched between two layers of reinforced ordinary concrete is generally used. The disadvantages of this structural system are: 1) The construction process is complicat...

AI Technical Summary

Problems solved by technology

In terms of the production of large external wall slabs for building industrialization in my country, a "sandwich" structure in which a layer of polystyrene board is sandwiched between two layers of reinforced ordinary concrete is generally used. The disadvantages of this structural system are: 1) The construction process is complicated The "sandwich" slab is composed of two layers of reinforced concrete and a layer of polystyrene board. During production, the bottom layer of reinforced concrete is poured first, and then the upper layer of reinforced concrete is poured after placing the polystyrene board. The three layers are also interspersed with polymer bars. Over-section connection, labor-intensive and time-consuming production, high labor and material costs

2) The durability of the insulation layer is much lower than that of the building structure. The design service life of the building structure is generally 50-100 years, while the polystyrene board will gradually degrade after 10-15 years and lose its insulation effect

It is not yet possible to realize the continuous pouring of the decorative layer, the bearing layer and the thermal insulation layer on the industrialized production line.
