Description

Preparation method of gypsum keel Technical Field The invention relates to a preparation method of a wall supporting device in the technical field of constructional engineering, in particular to a preparation method of a gypsum keel. Background The annual production of the industrial by-product gypsum in China is about 1.84 hundred million tons, the accumulated accumulation amount exceeds 10 hundred million tons, most of the industrial by-product gypsum is discarded as waste, and the waste residue accumulation occupies a large amount of land and pollutes the surrounding environment air, water quality and the earth surface, so that the development and utilization of the industrial by-product gypsum are one of the high and new technical industries which are encouraged to develop in China all the time. The gypsum spraying composite wall is a novel house building technology which is developed rapidly in recent years, and comprises a plurality of technologies of taking a light steel keel or PVC or metal plate as a framework, taking a steel plate net or glass fiber net cloth or plastic net as an adhesion layer and spraying gypsum mortar into the wall, wherein the light steel keel, the steel plate net and the gypsum spraying mortar arranged in the wall are the most mature technologies. However, in production practice, the requirements of engineering quality on light steel keels and steel plate meshes are large, and the corrosion resistance requirements on metal building materials are high, so that the manufacturing cost of the novel house building is high, and the large-scale popularization of the novel house building is limited. In addition, in the construction process of the gypsum composite wall body, standard lines (commonly called standard ribs) are required to be manufactured manually to control the flatness of the wall surface, skilled workers are required to manufacture the standard ribs, time and labor are wasted, labor cost is high, and the development of the technology is not facilitated. The development of the main material of the spray-type composite wall support column by using the industrial auxiliary gypsum can expand the capacity of gypsum dragon and solve the defects of the prior art, thereby being a particularly important problem for replacing and exceeding the building material options with light steel keels or PVC or metal plates as frameworks. Disclosure of Invention The invention aims to solve the technical problem of providing a preparation method of gypsum keels, and the light steel keels serving as supporting columns in the spray-type composite wall can be respectively prepared through two paths of the method, so that the problems that metal components of a non-bearing wall are easy to corrode, the standard ribs are difficult, the wall surface degree is uneven, and the wall manufacturing cost is high are completely solved. The invention solves the problems by adopting the technical scheme that the preparation method of the gypsum keel comprises the following steps of respectively manufacturing the gypsum keels with the same quality in a casting method or an engraving method under the control of a combined operation center: The first step, determining the structural form of a gypsum keel column of A+B or A+B1+B2 by a combined operation center, wherein A, B or B1 and B2 are respectively single gypsum keels, and B1+B2=B; Secondly, if gypsum keel stand columns with the same quality are respectively prepared on two production lines, according to an engraving method, under the control of a combined operation center, adopting a numerical control technology processing mode to produce the gypsum keel stand columns with mortise and tenon structures A+B or A+B1+B2; Or according to a pouring method, under the control of a combined operation center, a die A with a vent hole, a die B or dies B1 and B2 are firstly arranged, pouring is respectively carried out, and then the gypsum keel is assembled into the gypsum keel upright post in a mortise and tenon structure mode.
