Preparation mold and preparation method of building prefabricated composite block

Abstract

The invention discloses a preparation mold and preparation method of a building prefabricated composite block. The preparation mold is used for preparing the building prefabricated composite block filled with polystyrene in a block hole, the preparation mold is placed in a middle cavity of the block hole when in use, thus a space with low thickness and for filling a polystyrene foam material is formed between the mold and the middle cavity, the polystyrene foam material is heated through a heating module inside the mold, so as to make the material foam and adhere to the inner wall of the building prefabricated block, then the mold space is filled with polystyrene material blocks with regular shapes, and thus a high-strength, less-weight and energy-saving building prefabricated composite block is formed.

Description

technical field [0001] The invention relates to a preparation mold and a preparation method of concrete products, in particular to a preparation mold and a preparation method of building prefabricated composite blocks prepared from aerated concrete.

However, this method requires the introduction of high-pressure steam, which can easily lead to block cracking

CN102431079A proposes a production method of a polystyrene composite block, which discharges steam by setting a steam outlet to avoid cracking of the block. However, it needs to set a steam inlet on the upper surface of the hole of the block. If the foam is not sealed, the polystyrene foam will overflow the hole of the block through the steam inlet when it expands, which will affect the foaming quality

CN103042649A proposes a method for filling polystyrene bead materials in hollow bricks. It does not foam through water vapor, but foams polystyrene bead materials by setting heating plates on the upper and lower surfaces of hollow brick holes. However, Since polystyrene is a thermal insulation material, it is difficult to transmit the temperature of the heating plate to the middle of the hollow brick hole, resulting in poor foaming quality of the polystyrene bead material in the middle area of ​​the hollow brick, which affects the bonding effect between the middle area and the block hole
