Embodiment Construction

[0010] A method for producing a cast-in-place concrete hollow floor mandrel, the first step: material selection: select paper, quartz powder, Portland cement and fly ash as raw materials; the second step: crush the paper and add quartz powder , Portland cement and fly ash, and stir into a uniform slurry; the third step: pump the slurry into the homogenization tank, adjust the concentration, spray or copy the slurry onto the felt, and use a vacuum suction device , control the moisture of the slurry on the felt; the fourth step: roll the felt with the slurry on the forming cylinder for extrusion molding; the fifth step: after forming, cut the material and connect the embryo, and put the embryo into the autoclave Drying; Step 6: Cool after drying, polish and grind the edges with abrasive belts to get the board; Step 7: Cut the board, use wood as the inner support, glue the cut board with glue or fix it with air gun nails A box mandrel is formed on the inner bracket.

Abstract

The invention discloses a production method of a cast-in-place concrete hollow floor mandrel and a board produced by the method. Material selection: paper, quartz powder, portland cement and fly ash are selected as raw materials; the paper is pulverized and refined and then added with quartz powder , Portland cement and fly ash, and stir it into a uniform slurry; pump the slurry into the homogenization tank, adjust the concentration, spray or copy the slurry onto the felt, and use a vacuum suction device to control the amount of water on the felt. Moisture content of the slurry; roll the felt cloth with the slurry onto the molding cylinder and extrude it; after forming, the material is unloaded to connect the embryo, and the embryo is put into the autoclave for drying; after drying, it is cooled and polished with an abrasive belt Edge grinding to get the board; cutting the board, using wood as the inner support, glue the cut board with glue or fix it to the inner support with air gun nails to form a box mandrel. Beneficial effects: waterproof, fireproof, heat insulation, sound insulation, heat preservation effect, corrosion resistance, no harmful gas discharge, environmental protection, light weight, and low transportation cost.

Description

technical field [0001] The invention relates to a building upper plate and a production method thereof, in particular to a production method of a cast-in-place concrete hollow floor mandrel and a plate produced by the method. Background technique [0002] Existing mandrel is made of materials such as foam, plastics. Its defects mainly include: no fire prevention, harmful gas discharge, environmental pollution, not environmental protection. Using gypsum and glass fiber reinforced composite cylinder, the entire mandrel is bulky and heavy, which is not conducive to transportation, and the construction strength on site is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for producing a cast-in-place concrete hollow floor mandrel and a board produced by the method in view of the deficiencies in the prior art. [0004] In order to achieve the above object, the measures taken by the present invention: ...
