Spraying building type gypsum three-layer heat-preservation composite double-layer external wall body and preparation body thereof

Abstract

The invention relates to a spraying building type gypsum three-layer heat-preservation composite double-layer external wall body and a preparation method thereof. Through the wall body structure and the preparation method thereof, the energy-saving efficiency of an external wall can be greatly improved, the high requirements for heat preservation and energy saving in severe cold regions and cold regions are met, and meanwhile, a heat bridge is avoided; for example, in order to meet the building fireproofing demand, inorganic fireproof materials are adopted for outside heat preservation, and organic materials are adopted for intermediate heat preservation; the two kinds of materials are organically combined to achieve unity of efficient energy saving and fireproofing; through the technology, the simplest construction method of a fabricated building can be completed, that is, a concrete structure and a steel structure are used as main structures, and work such as heat preservation of enclosure parts comprising an internal partition wall and the external wall is completed by spraying building type gypsum composite materials; and through the technology, process by-product gypsum can beconsumed in quantity, waste is turned into treasure, and green hills and clear water of people are protected.

Description

technical field [0001] The invention relates to a wall structure in the technical field of construction engineering and a construction method for implementing the structure, in particular to a spray-built gypsum three-layer thermal insulation composite double-layer exterior wall and a preparation method thereof. Background technique [0002] The annual production of industrial by-product gypsum in my country is about 184 million tons, and the cumulative stockpiles exceed 500 million tons. However, the comprehensive utilization rate of the annual new generation is only 48.1%, and the unused part can only be stored in the open air. A large amount of gypsum waste slag is firstly occupied by a large amount of land; secondly, the investment in the slag yard is large and the operating cost is high, and the volume of the slag dump and the anti-seepage treatment of the foundation are strictly required; thirdly, precious sulfur resources are wasted; fourthly, the acid and Other harm...
