Production method of high-strength mortise-tenon structural building block

Abstract

The invention provides a production method of a high-strength mortise-tenon structural building block. The production method comprises the following steps: S100, sending powder into a mold cavity between an upper mold and a lower mold; S200, bidirectionally pressing a building block blank body by virtue of the upper mold and the lower mold, pressing a large end of the high-strength mortise-tenon structural building block by virtue of the upper mold, pressing the small end of the high-strength structural mortise-tenon structural building block by virtue of the lower mold, carrying out the secondary pressing independently by virtue of the lower mold after the bidirectional pressing of the upper mold and the lower mold, and forming a pressed building block blank body; S300, curing the pressed building block blank body by virtue of steam. The production method has beneficial effects that the building block blank body is bidirectionally pressed by the upper mold and the lower mold, the large end of the high-strength mortise-tenon structural building block is pressed by the upper mold, the small end of the high-strength mortise-tenon structural building block is pressed by the lower mold, the small end of the high-strength mortise-tenon structural building block is secondarily pressed independently by virtue of the lower mold after the building block blank body is bidirectionally pressed by the upper mold and the lower mold, and the high-strength mortise-tenon structural building block with a large end and a small end can be formed.

Description

technical field [0001] The invention relates to a method for making bricks, in particular to a method for making high-strength mortise and tenon structure blocks. Background technique [0002] Using fly ash, coal slag, coal gangue, tailings slag, chemical slag or natural sand, sea mud, industrial waste, waste incineration slag, etc. (one or more of the above raw materials) A high-strength mortise and tenon structure block manufactured by Yang technology. [0003] A high-strength mortise and tenon structure block, through high-pressure pressing and non-fired brick making technology, makes it possible to absorb tailings waste, industrial waste, construction waste, and desert sand and soil, and the absorption ratio is as high as 70-80%, which can realize One production line can consume thousands of tons of waste slag every day, and multiple production lines are rationally carrying out systematic industrialized engineering production all over the country, which will greatly red...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing high-strength mortise and tenon structure blocks are usually in the shape of a large end and a small end in order to realize the buckle connection. Due to its special shape, in the traditional one-way pressing process, it is impossible to ensure the integrity of each part of the block. The structure density is uniform, which causes the block to break during the pressing process and cannot be formed
