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

Abstract

The invention discloses a circulating type high-heat-preservation concrete block and a preparation method thereof, belongs to the technical field of concrete blocks, and can realize that a mortar pre-filling groove is formed in a block body and a circulating heat preservation component is embedded and mounted, so that on one hand, the strength of the block body and the connecting strength betweenadjacent block bodies can be improved; and on the other hand, on the inner side and the outer side of the interior of the block body, heat absorbing nets are formed through heat absorbing wires to absorb heat on the block body and then transferred to the inner heat absorbing balls, through sensing and comparison of the inner heat absorbing balls and outer heat dissipating balls to heat, after theinner heat absorbing balls absorb enough heat, due to the fact that the effect of the magnetic field triggered by a high-temperature side is stronger, circulation heat conduction connection is forcibly established, absorbed heat is returned to an original place, heat conduction connection is disconnected in the normal state, the excellent heat preservation performance of the block body is fully guaranteed, and meanwhile high strength and long service life are provided.

Description

technical field [0001] The invention relates to the technical field of concrete blocks, in particular to a circulating high 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 buildings. The use of this material c...
