Technical Field

The invention relates to a cold-formed thin-wall C-shaped steel edge-wrapped phosphogypsum module filling wall and a manufacturing method thereof, belonging to the technical field of combined filling of cold-formed thin-wall steel and phosphogypsum.

Background

The infilled wall is an important component in a frame structure and plays a role in containment and separation. In a frame structure building, the using amount of the filler wall is the largest in proportion, and the filler wall accounts for about 30 percent; therefore, the filler wall has great influence on the building function and the cost; at present, wall materials commonly used in practical engineering mainly include sintered hollow bricks, sintered perforated bricks, concrete small-sized hollow blocks, aerated concrete blocks, ceramsite concrete heat-insulating blocks and the like, and the materials need to play a role in enclosure and separation when applied, and also need to meet the heat-insulating and fire-proof requirements specified in civil construction thermal design specifications (GB 50176 + 2016) and building design fire-proof specifications (GB 50016 + 2014).

Scholars at home and abroad carry out a plurality of detailed researches on materials, performances and processes of the filler wall, part of achievements are written into specifications and applied to actual engineering, but the existing filler wall has a plurality of defects in both performance and application, and the defects are mainly summarized as follows: firstly, the filling wall material block is small, the filling wall material block is mostly constructed manually on site, and the construction process has the advantages of large workload, high labor cost and low construction speed; therefore, the construction cost and the construction period are greatly influenced; in addition, when in masonry, the masonry mortar is mixed on site, which often causes certain environmental pollution and forms building waste; secondly, when the infilled wall is constructed, tie bars need to be arranged in the wall body, so that the integrity between the wall body and the column body is ensured, and the cracking probability of the joint of the wall body and the column body is reduced; the existing method requires the wall tie bars to be reserved when the column is constructed or the tie bars to be implanted into the column in a bar implanting mode, so that the construction difficulty is improved, the construction cost is increased, and the position matching performance of the set tie bars and the wall mortar joints is relatively poor; thirdly, the filler wall has good heat preservation, heat insulation and fire resistance besides the functions of enclosure and separation; the existing wall material has good heat insulation performance but poor fireproof performance; or the fireproof performance is good, but the heat insulation performance is poor, so that the fireproof heat-insulating material is difficult to have the performances of two aspects; therefore, when the wall is constructed, necessary heat preservation, insulation and fire prevention structures are needed, and the structures inevitably increase the construction cost.

Aiming at the defects of the wall body, a more reasonable wall body filling technology is needed to be found so as to achieve the effects of convenience in construction, economy, reasonability, energy conservation, environmental protection and the like; in recent years, with the rapid development of the phosphorization industry, the proportion of the phosphogypsum in wall materials is increasing year by year; if the phosphogypsum is applied to a filling wall, the following advantages are achieved: firstly, the stockpiling amount of phosphogypsum in China is over 5 hundred million tons, the stockpiling amount is 6000 million tons newly added every year, the newly added land occupation is over 5000 hectares, and the stockpiling of a large amount of phosphogypsum not only occupies large-area soil, but also can bring environmental problems such as dust, underground water and soil pollution and disasters such as landslide. The phosphogypsum is applied to the filling wall body, so that the resource utilization can be realized, and the environment is protected; secondly, the phosphogypsum has good heat preservation and heat insulation performance, the heat conductivity coefficient is as low as 0.16W/(m.K), the energy consumption of a building can be effectively reduced, and the requirements of the building on energy conservation, emission reduction and the like are met; thirdly, the phosphogypsum contains about 21 percent of crystal water, and when a fire disaster occurs, the crystal water can absorb a large amount of heat energy to form a water vapor air curtain, so that the fire can be effectively prevented from spreading; therefore, the use of phosphogypsum in the filler wall can improve the fire resistance of the wall body; fourthly, the price of the phosphogypsum is low, the price of the phosphogypsum per cubic meter after hydration is about 140 yuan, which is only half of the price of the aerated concrete block and 40% of the price of the ceramsite concrete heat-insulating block, so that the phosphogypsum has good cost advantage when being used for filling walls.
