Pellet units, pellet assemblies, building block mold and method for making heat preservation building blocks

Abstract

The invention relates to pellet units, pellet assemblies, a building block mold and a method for making heat preservation building blocks. Each pellet assembly at least comprises two layers of pellet units, and every two adjacent pellet units are in mirror symmetry relative to the section between the two pellet units; each pellet unit is a cubic body and is provided with a concrete placement hole which is through along the vertical distance between two opposite-angle parallel sidelines in the cubic body; the building block mold comprises a pressing plate, a box frame with an opening in the top face and partition plates which are located in the box frame to equally divide the space inside the box frame; and the manufacturing method comprises the steps that the pellet assemblies are put into the equally-divided spaces, ceramsite concrete is poured into the box frame, after the ceramsite concrete solidifies, a ceramsite concrete blank body is taken out, each ceramsite concrete building block assembly with the corresponding pellet assembly is formed by cutting the ceramsite concrete blank body, then the section between two adjacent pellet units in each pellet assembly is cut, and heat preservation building blocks are formed. The manufacturing method is simple, high in efficiency, good in product stability and pressure resisting strength and suitable for production machining of the heat preservation building blocks in large batch.

Description

technical field [0001] The invention relates to the field of building materials, and relates to a core block unit, a core block assembly, a block mold and a method for making heat-insulating blocks for making heat-insulating blocks. Background technique [0002] There are many types of building wall materials in the market. Commonly used are cement blocks, sintered porous bricks, shale bricks, lime sand bricks, etc. These wall materials are low in price and poor in quality, and it is difficult to meet the requirements of modern buildings. Autoclaved aerated concrete blocks and light aggregate small blocks are commonly used as new wall materials. With the requirement of 65% energy-saving buildings in my country, the former two wall materials have low strength and high breakage rate. The shrinkage rate is relatively large, so it is not suitable for application on exterior walls; the latter has a high density and a large thermal conductivity, which makes it difficult to meet the...
