The construction personnel demonstrated the process of phosphogypsum mortar spraying.
All materials used, such as cold-formed thin-walled section steel, reinforced steel mesh and gypsum wall spraying mortar, are prefabricated in the factory and transported to the site for assembly.

The first mortar spraying and the second mortar spraying and leveling 2.
(3) Construction of damp proof course: 150mm from the ground, fine aggregate concrete is used for construction, and the thickness is the same as that of light steel keel.
(6) Repair and polishing: After the wall is sprayed, repair and polish the parts whose flatness does not meet the requirements.
(5) Shotcrete the second wall, spray mortar and scrape it flat: after the first mortar is sprayed and dried, spray 10mm thick light plastering mortar on both sides of the wall, flush with the rebar, and scrape along the rebar.
Phosphogypsum mortar spraying model wall The spraying type phosphogypsum composite wall technology belongs to one of the ‘fabricated’ buildings.
The construction personnel demonstrate the construction process of phosphogypsum mortar spraying: setting out → installation of light steel keel → installation of reinforced steel mesh → installation of water and electricity pipe trough → construction of damp proof course → plastering → first spraying → drying → screeding → second spraying and leveling → repair Polishing → The wall finished product acceptance technician is spraying phosphogypsum mortar (1) Install light steel keel: arrange the cold-formed lattice steel (keel) between snap lines, and use expansion screws to fix the keel and beam plate; According to the snapping position, install the columns on both sides and the middle beam column, and connect the upper and lower ends with self tapping screws; (Click on the official account of the 10 major technical categories of buildings) The gap between the upper guide beam, left and right columns and the beam column shall be filled with foam strips or foamed polyurethane.
Fixing Socket Waved End Nail Plate
The steel mesh shall be butt jointed at the column, and overlapping is prohibited; Install the 150 mm casting mesh on the other side, and consider embedding water and electricity casings, junction boxes, etc.
Buildings using the spray type phosphogypsum composite wall process are under orderly construction.

The spraying phosphogypsum composite internal partition wall is a composite wall formed by mechanical spraying, which uses cold-formed thin-walled steel and reinforced steel plate mesh as the framework, gypsum spraying mortar as the wall filler, and has light and high strength, adjustable thickness, unlimited height, variable shape, embedded pipeline, overall seamless, crack free, excellent sound insulation, earthquake resistance, fire protection, heat insulation Technical advantages of energy conservation.
The technology has the advantages of fast construction speed, safe construction, civilized construction, simple installation, simple management, etc.
Compared with the masonry wall, the type of work used is one fourth of the latter, The construction period is one sixth of the latter…
The materials are transported to the special mixing pump through the pneumatic conveying system for automatic watering, mixing and continuous spraying to form the wall.
(4) Shotcreting the first wall Shotcreting mortar: Shotcreting the first wall with a thickness of 40mm and troweling; 250 wide grid cloth shall be used for joint treatment with beam column joints.
(2) Install reinforced steel mesh: install reinforced steel mesh on one side, and fix it with the column with steel row nails at both ends and in the middle.
