Self-adaptive transposition type thermal insulation concrete block and preparation method thereof

Abstract

The invention discloses a self-adaptive transposition type thermal insulation concrete block and a preparation method thereof, and belongs to the technical field of concrete blocks. According to the self-adaptive transposition type thermal insulation concrete block, a mode of embedding an inorganic thermal insulation material into a block body is realized, so that on one hand, the weight of the block can be reduced, the structural strength is improved, on the other hand, heat energy transmission in the block body can be effectively isolated, meanwhile, a plurality of through holes are formed in the inorganic thermal insulation material in advance to achieve the integrated connection effect, the through holes serve as a structural bridge to enable the block body and the inorganic thermal insulation material to be formed a whole, special self-adaptive isolation balls are arranged, based on perception of heat transfer guide rods on the external heat energy, internal rotation action can betriggered according to heat energy distribution on two sides of the block body, so that self-adaptive collection of heat energy entering the block body is realized by utilizing transposition and transfer of a heat storage material and a cold storage material, a heat bridge or a cold bridge is avoided, the forming strength of the block body is effectively guaranteed, and meanwhile, the thermal insulation property of the block body is obviously improved.

Description

technical field [0001] The invention relates to the technical field of concrete blocks, and more specifically relates to an self-adaptive transposition type thermal insulation concrete block and a preparation method thereof. Background technique [0002] Air-entrained concrete block is a new type of building material that is lightweight, porous, thermal insulation, good fire resistance, nailable, sawable, planable, and has certain earthquake resistance. As early as the early 1930s, China began to produce this product, and it was widely used in high-rise frame structure buildings. It is an excellent new building material and has the advantages of environmental protection. [0003] The general quality of aerated concrete blocks is 500-700 kg / m3, which is only equivalent to 1 / 4-1 / 3 of clay bricks and lime-sand bricks, and 1 / 5 of ordinary concrete. It is a lighter type of concrete. It is suitable for filling walls of high-rise buildings and load-bearing walls of low-rise build...

Problems solved by technology

[0004] However, the existing aerated concrete blocks still have insufficient thermal insulation capacity. Therefore, after the masonry is formed, an insulation layer is required on the surface in most cases. The construction of the insulation layer is difficult and costly, and its service life is far shorter than that of building itself, and thus has a very limited
