Forming method for prefabricated hollow wallboard

Abstract

The invention discloses a forming method for a prefabricated hollow wallboard. The forming method comprises the following steps of S1, stirring a siliceous material containing natural stone powder, cement and fibers; S2, pressurizing the stirred material in a vacuum state to enhance the compactness of a plate; S3, performing extrusion molding through a specially-made or customized mold; S4, enabling an extruded forming plate to enter a curing kiln and performing primary curing to gradually harden the forming plate; S5, performing cutting machining according to the design or the requirement ofa customer for the plate; and S6, performing secondary curing on the extruded and molded plate in the high-temperature and high-pressure curing kiln and a high-pressure kettle in order to rapidly increase the strength of the plate and improve the permanent strength of the plate. According to the method, the strength, the compactness and the rigidity are high, and a large span can be supported, sothat the steel consumption in installation can be reduced, columns and keels are greatly reduced, the attractive effect is improved, and the economical efficiency is large.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a forming method of a prefabricated hollow wall panel. Background technique [0002] With the advancement of the industrialization of construction and housing, prefabricated lightweight wall panels, which are matched with high-rise buildings and frame structures, have gradually become the main component of today's wall materials and an inevitable development trend. Among them, as a new type of wall material, prefabricated hollow wall panels are widely used, and are mostly used as interior walls, exterior walls, roof panels, floors, enclosures, etc. Indoor use area, reduced labor intensity, improved building quality, moderate cost and other advantages, are currently gradually increasing the proportion of applications in various cities. [0003] Steel slag is the waste slag produced in the steelmaking industry, and its mineral composition includes olivine, dicalcium silicat...

Problems solved by technology

A large amount of construction waste is randomly piled up, which not only occupies the land, but also pollutes the environment, and directly or indirectly affects the air quality, leaving many safety hazards

And in the process of stacking and landfilling, due to the leaching and washing of fermentation and rainwater, as well as the soaking of surface water and groundwater, the leachate or leachate will cause serious pollution of the surrounding surface water and groundwater.
