Problems solved by technology
Even if airgel is used as the insulation material, due to the different locations of the materials used, the insulation time is difficult to be equal to the life of the house, and the insulation layer needs to be replaced midway. How to deal with and replace it has brought many new problems to construction and cost budget with trouble
The thermal insulation currently used is mostly internal thermal insulation or external thermal insulation, it is difficult to achieve the effect of sandwich insulation, so that the thermal insulation effect cannot reach the design life
Furthermore, the current thermal insulation wall basically adds an insulation layer on the basis of a ready-made wall, or adds an insulation layer on or inside a cast-in-place wall. Although there are several types of prefabricated insulation wall panels, their performance There are still many flaws in
In cold winter regions of our country, since inorganic thermal insulation materials can no longer meet the thermal insulation requirements of cold winter regions, organic materials with better thermal insulation performance than traditional inorganic thermal insulation materials have no choice but to choose. Security risks

Abstract
The invention discloses a precast aerogel reinforced concrete sandwich thermal insulation wallboard comprising an outer reinforced concrete protective layer and an inner reinforced concrete structure layer. Aerogel thermal insulation felt is arranged between the outer reinforced concrete protective layer and the inner reinforced concrete structure layer and anchored on the inner reinforced concrete structure layer and the outer reinforced concrete protective layer correspondingly through connecting pieces. The precast aerogel reinforced concrete sandwich thermal insulation wallboard has the advantages that the thickness of the thermal insulation materials is reduced, and the construction fire prevention safety degree is improved. The precast aerogel reinforced concrete sandwich thermal insulation wallboard breaks through an existing thermal insulation wallboard technology and conforms that the modern construction industry develops towards the industrialization, environmental friendly and energy-saving direction, meanwhile, the construction usable area is increased effectively, the precast aerogel reinforced concrete sandwich thermal insulation wallboard is favorable to the country, enterprises and people, the market prospects are wide, and significant economic benefits and great social benefits are achieved.
Description
technical field [0001] The invention relates to a thermal insulation wallboard in the construction field, in particular to a prefabricated airgel reinforced concrete sandwich thermal insulation wallboard. Background technique [0002] Under the background that the country and the Shanghai Municipal Government are vigorously developing prefabricated buildings and promoting the adjustment and upgrading of industrial structure, and at the same time advocating sustainable development of buildings that are green, energy-saving, emission-reducing, and environmentally friendly, the Shanghai Municipal Government has issued a policy starting in 2016. All new civil buildings within the outer ring line shall adopt prefabricated buildings, and the prefabricated assembly rate shall not be less than 40%. The external walls of prefabricated construction projects should adopt prefabricated sandwich insulation walls. Before the invention of this patent, the prefabricated sandwich insulation ...
