Description

Energy-saving composite brick or block

technical field

The utility model relates to an energy-saving masonry material in the field of building materials, in particular to an energy-saving composite brick or block that can be widely used in building outer protection structures and inner partition walls.

Background technique

Ordinary hollow bricks or blocks, porous bricks or blocks can only play a protective role when used in building exterior wall masonry construction due to their high thermal conductivity. The Chinese utility model patent named composite thermal insulation block or brick, authorized announcement number CN2703813Y proposes a scheme to improve the thermal performance of blocks or bricks, that is, in the holes of blocks or bricks with strip-shaped through holes Fill light-weight heat-resisting blocks or powder, or fill light-body heat-resisting blocks by fluid casting. But it has the following defects: one is that the composite thermal insulation block or brick adopts through holes, and when it is suitable for stacked masonry, there are interspersed solid columns in the holes of each layer, and this solid column is poured into the masonry by masonry mortar. If it is formed in the hole of the block or brick, the hollow block or brick part will become a solid block or brick, resulting in a significant drop in thermal resistance. The second is that the composite thermal insulation block or brick adopts an insulation gap of less than 2 cm in the middle and/or side to improve thermal resistance. The hole in the block will not increase the thermal resistance of the block or brick; if the gap is set on the side of the block or brick, the strength of the block will be reduced, and the mortar will flow into the side gap during masonry. to improve the thermal resistance. The third is that in actual construction, both the inside and outside of the wall may be slotted and drilled to bury pipelines, fixed hanging, etc., and light-weight heat-resistant blocks or powder close to the brick wall will be damaged and become invalid. Its 4th is that the outer wall of composite insulation block or brick and the rib of interior hole play the effect of thermal bridge, are unfavorable for improving the overall thermal resistance of block or brick.

A further solution is: the thermal insulation material refers to extruded polystyrene foam and its products, polystyrene foam and its products, polyethylene foam and its products, polyurethane foam and its products, polyvinyl chloride foam and its products, phenolic foam And its products, calcium plastic and its products, foam glass and its products, mineral wool and its products, rock wool and its products, glass wool and its products, composite silicate and its products, expanded perlite and its products, expanded vermiculite and its products, fly ash One or more of vitrified microbeads and their products, ceramsite and their products.

The beneficial effects of the utility model are:

1. The hole design of ordinary hollow bricks or blocks, porous bricks or blocks is optimized, and multiple rows of holes are set perpendicular to the direction of heat flow, and the number of rows of holes is limited. Within the limited range of rows, it can fully Make use of the thermal resistance superposition effect of the vertical air interlayer to improve the thermal insulation effect.

2. The holes filled with thermal insulation materials are arranged in the middle of energy-saving composite bricks or blocks, which can not only give full play to the high thermal resistance effect of thermal insulation materials, reduce thermal bridges, but also avoid the impact of wall slotting and opening on thermal insulation. Destruction of material properties.

3. There is a horizontal rib in the middle of the hole to disconnect the hole, which can improve the strength of the brick or block and meet the needs of actual use.

The patented energy-saving composite brick or block can fully meet the requirements of various energy-saving buildings on the wall heat transfer coefficient K≤1 (w/m ² .k) or even higher. At the same time, energy-saving composite bricks or blocks maintain important properties such as the basic strength, durability, construction convenience, and exterior decoration diversity of ordinary hollow bricks or blocks. Thermal insulation, has great practical promotion value.
