Preparation method of reclaimed self-heat-insulation building block

Abstract

The invention relates to a preparation method of a reclaimed self-heat-insulation building block. The method comprises the following steps of: arranging a die frame on a soleplate and arranging a core material die in the die frame; firstly injecting concrete slurry toward the bottom of the core material die under the condition that a gap exists between the bottom end of the core material die and the soleplate; then, injecting the core material into the core material die and injecting a slurry core material into the core material die under the condition that the bottom end of the core material die is arranged on the soleplate; compacting the core material into a core block and taking out the core material die upwards; injecting concrete slurry into various spaces left after the core material die is taken out; trowelling and compacting the outer end surface of the building block; standing still until the concrete slurry is finally condensed and taking off the die frame; and naturally curing the formed self-heat-insulation building block and separating the building block from the soleplate. By means of the preparation method provided by the invention, a building block blank is prepared by means of once material injection so that various structures can be mutually combined into a firm whole. The invention can realize the building block construction by fully wrapping a core material in a concrete wall, wherein the core material is prepared by mixing paper-making slurry, straws, and the like.

Description

technical field [0001] The invention relates to a self-insulating block and a preparation method thereof. Background technique [0002] The basic structure of an existing energy-saving and waste-recycling self-insulating block filled with core material is as follows: a block matrix with a cavity is constructed from an outer wall, an inner wall, and end ribs, and the core material is filled in the cavity. In order to improve the masonry strength and shear strength of this kind of block, some internal ribs can be added in the cavity of the block base, or sealing ribs and connecting columns can be added at both ends of the block base. To improve the thermal insulation of the block, an insulation layer and a protective layer can be added on the outside of the outer wall. At present, the above-mentioned blocks are produced by horizontal pouring molding method, and in the pouring process, the inner wall, end ribs, and inner ribs are respectively poured out with the outer mold...

Problems solved by technology

The disadvantages of this method are: 1. The production process is more cumbersome and the production process is longer; the layers are distributed multiple times, and the forming mold is taken out during the period, which is easy to cause the outer wall or inner wall and the end ribs and inner ribs, the block matrix and the core material. The hidden danger of unreliable connection between
