Energy-saving glass pumice concrete building block hole type

Abstract

The invention discloses an energy-saving glass pumice concrete building block hole type, and aims to provide a building block which can block solar shortwave radiation and intercept ground long wave radiation in order to achieve a heat insulation effect. The technical scheme is characterized in that the energy-saving glass pumice concrete building block hole type comprises a building block and holes, wherein the holes are distributed in the surface of the building block; the holes are rectangular or T-shaped; five layers of holes are sequentially distributed from top to bottom, and marked as alayer A, a layer B, a layer C, a layer D and a layer E respectively; the layer E and the layer A are of the same structure; the layer B and the layer D are of the same structure; the layer C comprises multiple groups of holes of different specifications; and the holes in the layer A, the layer B, the layer C, the layer D and the layer E are arranged in a staggered way.

Description

technical field [0001] The invention relates to the technical field of thermal insulation hollow blocks, in particular to an energy-saving glass pumice concrete block pass. Background technique [0002] At present, most of the self-insulating hollow blocks on the market are in the shape of circles and diamonds. Under the condition of ensuring the same porosity of the hollow blocks, comparing the thermal resistance of different hole types can be obtained from large to small. The order is rectangular hole, rhombus hole, square hole, and circular hole. The air in the rectangular hole is more conducive to long-distance convection, thereby increasing the heat transfer path and increasing the thermal resistance of the hollow block; while for the rhombus hole, square hole, For circular holes, the air is more likely to produce short-circuit convection, which shortens the heat transfer path of the hollow block, thereby reducing the thermal resistance of the hollow block.
