s1: determining the size and thickness of the wall according to the requirements of weather zones, stress performance and the like; determining the size of a reinforcing steel bar mesh 8 and the reinforcing steel bar interval of the reinforced concrete outer template 1 according to the size of the wall; determining the size of the connecting piece 3 and the sizes of the first plug 4 and the second plug 5 at two ends according to the thickness of the wall; determining the size of the concrete external template 1 according to the length and the width of the wall; a wall body side formwork is made according to the size of the concrete external formwork 1, and the side formwork is installed on a formwork table; and semicircular bulges with the diameter of 1cm are arranged on the side forms so as to facilitate the later pouring of the position of the sealing rubber strip 11 reserved on the concrete outer template 1.
S2: uniformly welding the internal connecting pieces at intersections of the reinforcing mesh sheets 8 in a quincuncial arrangement, and respectively welding the peripheral connecting pieces at the four corners and the middle points of the edges of the reinforcing mesh sheets 8;
s3: the reinforcing mesh 8 is padded to a standard height by using a prefabricated plastic cushion block, and the reinforcing mesh 8 is ensured to be positioned at the center of the concrete outer formwork 1;
s4: pouring concrete, and curing and forming; the thickness of the concrete is controlled to be 30 mm. The mould platform is vibrated when the concrete is poured, so that the concrete pouring is more uniform, the condition that the reinforced concrete outer template 1 has gaps is effectively avoided, the reinforced concrete outer template 1 is firmer, and the bearing capacity is stronger.
S5: vertically placing the cured and formed outer formworks 1 on a horizontal formwork table in pairs, and mutually overlapping L-shaped long edges of corresponding internal connecting pieces on the two concrete outer formworks 1, wherein the overlapping length is 50 mm; the L-shaped long edges of 8 peripheral connecting pieces (which can be increased or decreased according to the actual requirements according to the size of the wall plate) are connected and fixed by bolts 9, so that the two reinforced concrete outer formworks 1 can be ensured not to move in a staggered manner;
s6: two ends of the outer template 1 are plugged by a first plug 4 and a second plug 5; in order to fix the first and second plugs 4 and 5 at the two ends, a steel sheet 6 with square holes at the two ends is respectively placed on the outer sides of the two fixed outer templates 1, a square steel pipe 7 is inserted into the square holes, and a wooden wedge 10 is inserted between the square steel pipe 7 and the plugs to fix the first and second plugs 4 and 5. More than one device is positioned at each of the walls 1/4, 3/4 in height.
S7: pouring ardealite; pouring phosphogypsum 2 into the fixed reinforced concrete outer formwork 1, and trowelling the phosphogypsum 2 on the upper side and the reinforced concrete outer formwork 1.
S8: after maintenance and molding, the first and second plugs 4 and 5 are removed; and (5) after the phosphogypsum 2 in the phosphogypsum composite wallboard is hardened, disassembling the plugs at the two ends and the parts for fixing the plugs. When the phosphogypsum composite wallboard is used, a sealing rubber strip 11 is placed at the semicircular groove of the concrete outer template 1 to ensure the airtightness of the wall. The wall boards are vertically installed, the sealing rubber strips 11 are also vertical, and the sealing rubber strips 11 are placed between two parallel vertical wall boards for water proofing during installation.
Further, the step of determining the size of the connecting element 3 according to the thickness of the wall body is followed by manufacturing the connecting element 3. The steps of making the connector 3 include:
choose the steel sheet that thickness is 2mm for use, process into the billet that the width is 20mm (or directly choose for use thickness to be 2mm, the billet that the width is 20 mm), it is reserve to cut into the billet that length is L according to the whole thickness of wall body. The specific way of calculating L is as follows:
L＝D/2+75
in the formula: l-length of steel strip
D-wall thickness
Unit: mm is
Note: the lap length is 50mm
The cut steel bars are marked at a position 50mm away from one end along the length direction, and bent to 90 degrees in the same direction at the marked position to form an L-shaped internal connecting piece (as shown in fig. 8). And reserving cross-shaped holes on the long edge part of the L-shaped steel sheet to manufacture a peripheral connecting piece (as shown in figure 9).
In the embodiment, the two reinforced concrete outer formworks 1 are respectively poured, so that the efficiency is improved, the process is simplified, the prefabrication time is shortened, the site construction procedures are simplified, the construction efficiency is greatly improved, the quality and the safety performance are improved, and the construction period is shortened.
The assembled phosphogypsum composite wall board and the prefabrication method thereof according to the present invention are described in detail with reference to the preferred technical solution thereof, however, it should be noted that those skilled in the art can make any alterations, modifications and variations on the above disclosure without departing from the spirit of the present invention. The invention includes the specific embodiments described above and any equivalents thereof.
