S6, grouting, namely injecting slurry prepared from phosphogypsum into the wall building cavity 3 from the grouting holes 21 until slurry overflows continuously in the slurry leakage holes 22, and stopping grouting; the slurry is formed by mixing modified phosphogypsum powder, water, an additive and ceramsite, wherein the additive is a water reducer capable of improving fluidity, such as lignosulfonate, naphthalene sulfonate formaldehyde polymer and the like. After grouting is completed and slurry in the wall building cavity 3 is initially set, the grouting holes 21 and the slurry leakage holes 22 are plugged by mixed slurry of modified phosphogypsum powder and water, and trowelling is performed.
Thus, when the partition wall construction is carried out, the lattice column 1 and the phosphogypsum boards 2 are enclosed to form the wall building cavity 3, and as the phosphogypsum boards 2 are formed by mixing and pressing phosphogypsum powder, water and the like, the surface and edge flatness of the phosphogypsum boards 2 are higher, and the joint between every two phosphogypsum boards 2 after being spliced is smaller, so that the condition of slurry leakage can be greatly reduced when slurry is pressed into the wall building cavity 3.
Meanwhile, the slurry added into the wall building cavity 3 contains ceramsite and additive, the ceramsite is light and has more pores, and the slurry is mixed in phosphogypsum powder to ensure that the whole slurry is heterogeneous, so that the heat preservation and sound insulation effects of the formed partition wall can be effectively improved. The additive can improve the fluidity of the slurry in the wall building cavity 3, and phosphogypsum powder can be finally set within 30 minutes after initial setting for 5-6 minutes, so that the slurry can rapidly fill the whole wall building cavity 3 and be quickly set, and compared with the conventional cast-in-situ concrete wall, the slurry is less than 6 hours and is more maintained for 2-5 days in molding time, and the construction method greatly shortens the construction period and improves the construction efficiency.
By means of the characteristics of high self hardness and high surface smoothness of the phosphogypsum board 2, the phosphogypsum board 2 can serve as a template, a wall decoration board, a heat-insulating board, a sound-insulating board and the like in the application, repeated dismantling is not needed, the generation of construction waste on a construction site can be reduced, the construction process of a partition wall can be simplified, the construction efficiency is improved, and the innovation of the construction process of the partition wall is promoted; and the phosphogypsum board 2 on the appearance and the solidified slurry form a solid partition wall, compared with a conventional keel type hollow wall, the partition wall manufactured by the application has good sound insulation and heat preservation performance, has higher strength and hardness, has stronger fireproof performance, can mount heavy objects, and has wider applicability.
Considering that the time consumption and quality of the flat joint in the step S4 can influence the grouting effect, the slurry used for the flat joint in the step S4 is formed by mixing phosphogypsum, water and cement, and the proportion of the cement to the phosphogypsum is 1:3-1:9. In this way, cement is added into the phosphogypsum powder slurry, so that the setting time of the slurry is prolonged, but the bonding strength of the flat joint slurry can be further improved, the blocking effect on each gap is further improved, and the slurry leakage is avoided when the slurry is pressed into the wall building cavity 3.
Correspondingly, in order to further ensure the sealing performance of the phosphogypsum boards 2 after being assembled, the joint parts of the phosphogypsum boards 2 are coated with adhesive before being assembled and arranged in the step S3, and the adhesive can be structural adhesive or a mixture of phosphogypsum powder and water. Thus, after the two adjacent phosphogypsum boards 2 are tensioned, redundant adhesive at the joint parts of the two phosphogypsum boards is extruded, and if the edges of the phosphogypsum boards 2 are knocked to generate pits in the transportation process, the adhesive can be filled into the pits, so that the tightness between the two adjacent phosphogypsum boards 2 is ensured.

The adjusting grooves 44 comprise straight groove sections 441 and arc groove sections 442 which are communicated, the extending direction of the straight groove sections 441 is orthogonal to the length direction of the cross rod 43, the adjusting grooves 44 in the same group correspond to the same phosphogypsum board 2 splice joint, and the arc groove sections 442 in the adjusting grooves 44 in the same group are in a reverse arc shape in an eight shape.
It is further defined that, with reference to fig. 2 and 4, the spacing between two straight trough sections 441 is twice the distance of the adjustment post 42 from the adjacent phosphogypsum board 2 edge. In order to ensure the guiding function of the adjusting groove 44 to the adjusting column 42, the cross bar 43 is welded with a reinforcing bar 46 along the outline of the outer edge of the adjusting groove 44, and in the case of arranging the cross bar 43 as a square tube, the reinforcing bar 46 may be welded on the inner wall or the outer wall of the square tube.
