The construction process flow is as follows: processing a wall surface base layer 1 → squaring an infrared system in a room → dotting a gypsum positioning block 3 → constructing a gypsum positioning strip 8 → reinforcing bars, repairing bars, installing corner protectors → debugging equipment and mixing slurry → spraying a gypsum filling layer 7 → leveling and repairing → polishing and smoothing; the specific operation steps are as follows.

Step one, in the process of treating the wall surface base layer 1, the measures described in the following table can be referred to:

。

secondly, the infrared system in the room finds the square and just selects a longer wall as the reference of the central axis of the room according to the house type characteristics, and an infrared instrument is used for positioning the central axis; the other rooms are lined by infrared instrument lines on the basis of the central axis, and the central control axis of each room is quickly positioned; two infrared instruments are used for placing diagonal positions and pulling transverse and vertical lines to control the square of a room (the square needs to be controlled within 5 mm), and after the paying-off of each room is finished, the longitudinal and transverse directions must be controlled within +/-5 mm.

Step three, gypsum dotting: according to the main axis infrared ray in the room, hanging the vertical part, sleeving the square part and finding the gauge according to the flat vertical condition of the surface of the wall surface base layer 1; covering a square by using mobile infrared rays, and punching a square gypsum positioning block 3 on the interface bonding layer 2; before plastering and leveling, the thickness of a gypsum positioning block 3 is determined on the interface bonding layer 2, and the gypsum positioning block 3 is made for ensuring the level and the verticality and is used for controlling the construction quality; when the gypsum positioning blocks 3 are dotted, transverse lines need to be pulled to ensure that all the gypsum positioning blocks 3 on each structural surface are positioned on one plane (the vertical and the flat positions are controlled to be 1 mm), and the distance between the gypsum positioning blocks 3 and the wall edge is within 200mm, and one gypsum positioning block is positioned at 1500mm square; since the later gypsum positioning strip 8 is strip-shaped, the verticality of the strip-shaped surface can be better controlled.

When the gypsum positioning strips 8, namely the reinforcement punching, are constructed, firstly, construction is carried out strictly according to the size and position requirements of paying-off and dotting, and the number of the gypsum positioning strips 8 cannot be reduced; and then checking whether the parts such as the structural seams, the wire conduit slots and the like are adhered with gridding cloth or not and the construction quality, and timely processing the parts which are missed and can not meet the quality requirement.

Step four, 5, rib repairing and corner protection installation: the end part of the gypsum positioning strip 8 is provided with an inclined opening to facilitate bar connection, the mortar bar which is not punched to the surface is subjected to bar compounding, and after the bar connection is finished, actual measurement personnel perform vertical, flat and smooth inspection, find problems and repair in time to ensure the quality of the gypsum positioning strip 8; after the rib punching and the rib connecting are finished, the checking is carried out, the problem is found and repaired in time, and the quality of the gypsum positioning strip 8 is ensured.

After the gypsum positioning strip 8 is constructed, the corner protection parts of the door and the window are checked, and the corners are straightened by adopting a plumb line to ensure that the corners are smooth and vertical (controlled to be +/-2 mm); finally, gypsum is used for installing the external corner protection angle according to the method of punching ribs; the sizes of the door opening and the window are strictly controlled (the size of the door opening and the size of the window are controlled to be +/-2 mm).

According to the condition of the structural surface, the adhesive mesh cloth can be added; the strict requirements are as follows: firstly, leveling the full batch of gypsum mortar → spreading and laying the grid cloth to be smooth → leveling the full batch of gypsum mortar; or the whole surface is added with a brushing interface agent.

Step five, equipment debugging and slurry blending: firstly, ensuring enough water pressure, if the water pressure is not enough, adopting a method of externally connecting a booster pump to solve the problem, if the water pressure is too high, increasing a ball valve switch to control the water quantity; the overlong water pipe is avoided as much as possible, so that the insufficient or unstable water pressure is avoided, and the guniting effect is not influenced; all the connecting pieces are ensured to be firmly connected, so that the falling off is prevented, the construction is influenced, and a container which can be filled with clear water, a booster pump and a suction filter are still prepared on site for standby; before starting up, locking the machine fixed wheel, connecting the water pipe, opening the input pipeline, evacuating the air in the pipe, removing dirt, and then closing the input pipeline; manually adjusting a needle valve to adjust the water inflow, adjusting the water level to about 650 according to the first use suggestion, checking the water level, and injecting water into the mixing bin, wherein the water level is just at the position 1/3 of the mixing bin; adding spraying gypsum into a hopper, simultaneously rotating a grid wheel switch to an 'automatic' state, opening a green starting button, observing the consistency of overflowed mortar, and finely adjusting to a proper consistency by using an adjusting needle valve; pressing a red button to confirm the end of the operation, connecting the air pipe with the air valve and the ejector, and then starting the air compressor; then the mortar pipe is wetted by water, and is connected with a mortar outlet and an ejector of the machine, a green starting button is turned on to enable the machine to enter a standby state, an air valve on the ejector is turned on to enable the machine to operate, and meanwhile, a nozzle is adjusted to be in an optimal state, so that spraying can be carried out; the amount of the slurry to be stirred each time is determined, not too much slurry (the slurry must be used up before initial setting, water cannot be added in the using process, and the coagulated ash cannot be added with water for stirring and using any more), and the consistency of the plastering slurry is thinner than that of the normal plastering slurry in high-temperature weather in summer.

Step six, gypsum spraying: arranging a spraying machine in place after the reinforcement on the wall surface is finished and hardened; the operators are suitable for four persons in total, one person is responsible for charging and monitoring equipment, one person is responsible for spraying gypsum, and the other two persons are responsible for scraping the gypsum; when spraying, the distance between the nozzle and the object surface is preferably 300-400 mm; too close to easily sag; the gypsum is uneven too far, so that pits are easy to appear, and the gypsum scattered on the way from the nozzle to the object surface is wasted; the specific size of the distance is properly adjusted according to the type, viscosity and air pressure of the gypsum, the spraying distance of the slow-drying gypsum can be a little longer, and the spraying distance of the quick-drying gypsum can be a little shorter; the spray gun moves up and down and left and right in sequence and operates uniformly at the speed of 10-12 m/min, and the spray nozzle is required to be sprayed on the object plane straightly, so that the inclined spraying is reduced as much as possible. When the spray gun is sprayed to the two ends of the object surface, the hand pulling the trigger of the spray gun needs to be loosened quickly, so that the gypsum fog is reduced, and the two ends of the object surface are usually sprayed for more than two times, which is the place most prone to causing sagging; when spraying, the next pass is required to press 1/3 or 1/4 of the previous pass, so that the phenomenon of missing spraying cannot occur; adjusting the thickness of the slurry within a small range of 10-50 mm according to the viscosity of the slurry, wherein the thickness of the slurry sprayed at one time is 5-20 mm; and according to the plaster leveling layer number, the gridding cloth can be pasted.

Step seven, strickling and repairing: after the spraying is finished, one person then uses an H-shaped scraper to vertically and horizontally scrape once, and the surfaces of the upper and lower punching ribs are tightly adhered to scrape redundant slurry from left to right, and meanwhile, the insufficient part is filled; the working procedure can be repeated for a plurality of times before the slurry is initially set until the wall surface is flat; then comprehensively checking whether the bottom ash is smooth and flat, and checking the vertical condition of the wall surface and the flat condition of the wall surface by using a wire supporting plate; the spraying thickness is more than 20mm, layered construction is needed, and when the bottom ash is dried, the surface layer gypsum spraying operation can be started; after the wall surface is leveled, the internal and external corner parts are sprayed and scraped to be vertical, the peripheries of the holes, the electric box, the groove and the box are left to be smoothed and leveled, and the wall surface needs to be sprayed and scraped to be a plaster rib surface and be leveled and smooth; in the spraying and scraping process, quality problems such as hollowing, bubbles, cracks and the like are required to be repaired and processed in time, follow-up repair is achieved after spraying and scraping of each room is completed, and work completion and site cleaning are achieved on a construction site.

Step eight, polishing and light collecting: after the scraped gypsum is initially set, a 3mT type scraper is used for secondary leveling; then a spray can is used for spraying water to the surface of the initial setting gypsum for moistening, the water spraying amount is not too much, and a sponge trowel is used for polishing and extracting the slurry while spraying water.

In the embodiment, the mixed mortar is used up within 60 minutes, and the hardened mortar and the ground mortar cannot be added with water for secondary use; the operation tool and the container are cleaned when used up, otherwise the use effect of the sprayed plaster is influenced.

In the embodiment, in rainy days, the gypsum powder is easy to damp and agglomerate, so that the gypsum powder is prevented from being transported in rainy days; in a high-temperature period, the surface setting time of the gypsum mortar is about 30 minutes, the material after being scraped is immediately collected and reused, otherwise, the material is easy to harden; the water content of the slurry is easily absorbed by the wall substrate and the water content is volatilized quickly, so that the plastering gypsum lacks the water content required by hydration, and cracks and hollows appear.

In the embodiment, the consistency of the gypsum mortar is required to be carried out when the mortar pipe is not connected with a machine and the air compressor is not started, the mortar pipe is soaked by water before use, and the surplus water is emptied and then is connected to a mortar outlet of the machine, so that the mortar pipe is prevented from being blocked; if the pause time is too long or the spraying is finished, the mixing bin and the mortar pipe of the machine need to be cleaned immediately, so that the blockage caused by the solidification of the gypsum mortar is avoided; if the device is stopped for a short time, the air valve on the ejector needs to be opened for 20-30 seconds after about 10 minutes, and the gypsum mortar is prevented from being solidified.

In the embodiment, after construction is finished, finished product protection among professionals is required, mutual collision is avoided, indoor ventilation is kept, and equipment is cleaned according to a correct mechanical use method.

In the embodiment, before guniting, a layer of rubber plate is paved on the wall along the ground, so that the ground ash in the plastering process can be recycled for continuous use. However, the slurry which is coagulated or is to be coagulated can not be reused, so that the ground ash must be recycled at any time during plastering so as to avoid waste.

The above embodiments are not exhaustive of the specific embodiments, and other embodiments are possible, and the above embodiments are intended to illustrate, but not limit the scope of the present invention, and all applications coming from the simple changes of the present invention fall within the scope of the present invention.
