DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] like Figures 1 to 9 As shown, the present invention provides a plaster-free masonry wall anti-cracking process for building wall construction, and the anti-cracking process includes the following steps: S1: Use high-precision masonry to operate according to masonry requirements, control the verticality and flatness of the masonry wall 7 to be good, and then roll the interface agent on the surface of the wall 7; S2: Prepare the mortar and apply it to the surface of the wall 7 using a smearing device to form a surface decoration layer 71; S3: After applying the mortar to the wall 7, hang an alkali-resistant mesh cloth on the wall surface after applying the mortar; Wherein, the surface decoration layer 71 at least includes a bottom anti-cracking putty layer, a surface putty layer, and a finishing layer. In the step S3, the anti-alkali mesh cloth is pressed into the bottom anti-cracking putty layer and the surface putty layer, and the anti-alkali mesh cloths are connected and fixed to each other by fixing nails; Wherein, the paddle device in step S2 includes a bottom plate 1, a fixed column 2 is installed on the bottom plate 1, a movable block 211 driven by a motor 22 is installed on the fixed column 2, a mounting plate 3 is installed on the movable block 211, a scraper 4 is installed on the mounting plate 3, a material storage trough 31 is provided on the mounting plate 3, a material discharge port 311 is provided on the scraper 4, and the material discharge port 311 is communicated with the opening of the material storage trough 31; A slurry barrel 11 is installed on the bottom plate 1, and the slurry in the slurry barrel 11 is transported to the storage tank 31 through a slurry pump 12; A collecting plate 5 is installed below the mounting plate 3, and the collecting plate 5 is in contact with the surface of the wall 7. The squeegee device squeegees the wall surface from top to bottom through the scraper 4; The fixed columns 2 on the bottom plate 1 are symmetrically arranged, and a mounting groove is provided on the fixed columns 2. A screw 21 is rotatably installed in the mounting groove, and a movable block 211 is installed on the screw 21. The screw 21 is driven by a motor 22 installed on the lower surface of the bottom plate 1, and the two screws 21 are synchronously rotated through a transmission structure. At the same time, the slurry barrel 11 and the slurry pump 12 are connected through a connecting pipe 14, and the slurry pump 12 and the storage tank 31 are connected through a delivery pipe 15, so as to stably and quantitatively deliver the prepared slurry in the slurry barrel 11 to the storage tank 31; Use high-precision blocks to build the wall 7, so that the verticality and flatness of the wall 7 surface are good, and the wall 7 surface meets the quality standards of the decorative surface layer of the building wall 7, eliminating the need for a plaster layer, thereby achieving the purpose of reducing the construction cost of the anti-cracking agent; After the wall 7 is built, the uneven parts of the wall 7 are polished and smoothed, and the corners and recesses of the wall 7 are filled and repaired to make the wall surface meet the flatness requirements. After that, the oil stains, floating dust, etc. on the surface of the wall 7 are cleaned to ensure that the surface of the wall 7 is clean, which is convenient for the subsequent rolling of the interface agent to ensure that the interface agent has a good brushing effect. After that, the staff prepares the mortar to be used, such as the bottom anti-cracking putty or the surface putty, and adds it to the paddle liquid cylinder in the paddle device. The mortar is evenly and evenly applied to the surface of the wall 7 through the paddle device, thereby completing the construction of the surface decoration layer 71; At the same time, during the construction process, the anti-alkali mesh cloth is pressed into the bottom anti-cracking putty layer and the surface putty layer, and the stability of the anti-alkali mesh cloth's own structure is used to improve the structural strength of each putty layer after smearing, thereby avoiding cracks on each putty layer. At the same time, since the anti-alkali mesh cloths are interconnected and fixed by fixing nails, the anti-alkali mesh cloths in different putty layers are further interconnected to form a whole, thereby improving the structural strength of the connection between each putty layer and between the putty layer and the wall 7 surface, thereby performing anti-cracking reinforcement on the surface decoration layer 71 on the wall 7 surface and improving the anti-cracking effect of the wall surface; At the same time, when plastering the wall, the mortar prepared by the staff is added into the slurry barrel, and then the staff pushes the plastering device to move to the wall to be constructed, so that the scraper 4 can be closely attached to the surface of the wall 7, and then the controller controls the motor 22 to run and drive the screw 21 to rotate, so that the scraper 4 moves to a high position, thereby plastering the wall from top to bottom; When plastering the wall, the slurry pump 12 extracts mortar from the slurry barrel 11 through the connecting pipe 14, and then delivers the extracted mortar to the storage tank 31 through the delivery pipe 15, so that the mortar is covered on the wall from the outlet of the storage tank 31 and the outlet 311 on the scraper 4. After that, as the scraper 4 moves, the plastering operation is completed, so that the wall surface after plastering is flat and smooth. At the same time, the storage tank 31 provided on the mounting plate 3 allows the delivered mortar to be temporarily stored, and allows the mortar to fill the discharge port 311 on the scraper 4, so that when the scraper 4 is smearing the wall surface, the mortar can be evenly applied to the wall surface, thereby ensuring that the surface decoration layer 71 on the wall surface is flat and uniform, and improving the construction quality of the surface decoration layer 71; At the same time, when the scraper 4 applies the mortar to the wall, the mortar may overflow and drip downwards. The collecting plate 5 installed under the mounting plate 3 is used to collect the overflowing and dripping mortar to prevent this part of the slurry from falling onto the ground and contaminating the ground and wall, making subsequent cleaning difficult, and causing mortar waste, thereby increasing construction costs.

[0019] As an embodiment of the present invention, a contact roller 51 is installed on one end of the collecting plate 5 close to the wall 7, and the contact roller 51 is in contact with the surface of the wall 7; An elastic deformation layer is installed on the surface of the contact roller 51, and the distance between the collection surface 53 of the collection plate 5 for receiving the fallen mortar and the contact roller 51 is less than or equal to the thickness of the elastic deformation layer; A recovery pump 13 is installed on the bottom plate 1, and the recovery pump 13 is connected to the slurry barrel 11 through a connecting pipe 14. A recovery pipe 16 is installed between the recovery pump 13 and the collecting plate 5. A common centralizing pipe 52 is installed on the collecting surface 53 of the collecting plate 5. A soft auger 521 is installed in the centralizing pipe 52, and the soft auger 521 extends into the recovery pipe 16. When the scraper 4 is wiping the wall from top to bottom, the collecting plate 5 located below the mounting plate 3 collects the slurry overflowing and falling from the scraper 4 and between the scraper 4 and the wall. At the same time, when the collecting plate 5 moves downward together with the scraper 4, the contact roller 51 on the collecting plate 5 rotates counterclockwise, that is, as the contact roller 51 rotates, the dripping slurry close to the wall is gradually rotated to the collecting surface 53 of the collecting plate 5, thereby improving the collection effect of the overflowing and falling slurry and reducing the possibility of the slurry dripping to the ground or adhering to the wall below. At the same time, the elastic deformation layer on the surface of the contact roller 51 allows the contact roller 51 to be closely attached to the wall surface, thereby avoiding a gap between the contact roller 51 and the wall surface, causing the fallen slurry to slide from the gap. At the same time, the distance between the collecting surface 53 and the contact roller 51 is less than the thickness of the elastic deformation layer, so that the collecting surface 53 is closely attached to and squeezed on the elastic deformation layer, further eliminating the gap between the contact roller 51 and the collecting surface 53, so that the slurry falling on the contact roller 51 can be fully scraped onto the collecting surface 53, thereby avoiding the slurry from contacting the wall surface again or dripping onto the ground as the contact roller 51 rotates, causing ground pollution, slurry waste, and subsequent difficulty in cleaning. At the same time, after the overflowed or fallen slurry is collected on the collecting plate 5, the slurry will flow under the action of the inclined collecting surface 53 and then contact the collecting pipe 52. At this time, the recovery pump 13 on the bottom plate 1 will drive the recovery pipe 16 and the soft auger 521 in the collecting pipe 52 to rotate, and push the slurry contacting the collecting pipe 52, so that the collected slurry can be taken away from the collecting plate 5 and returned to the slurry barrel 11, so as to improve the utilization rate of the slurry and avoid slurry waste. At the same time, by moving the slurry on the collecting plate 5 through the soft auger 521, it can also avoid too much slurry on the collecting plate 5, which affects the slurry collection effect.

[0020] As an embodiment of the present invention, an elastic sheet 33 is installed at the opening of the material storage tank 31, and the elastic sheet 33 covers the opening of the material storage tank 31; The opening of the storage tank 31 is blocked by the elastic sheet 33, so that the mortar entering the storage tank 31 needs to fill the storage tank 31 or be evenly distributed in the storage tank 31 before it can be discharged from the opening of the storage tank 31, and then wait for the scraper 4 to evenly spread it on the wall. In this process, the elastic sheet 33 blocks the opening, and the slurry can be distributed to the opening of the storage tank 31 as evenly as possible, and then when the slurry passes through the opening and contacts the wall, the slurry is distributed relatively evenly on the wall, which is convenient for the scraper 4 to smooth the slurry on the wall, avoiding the uneven distribution of the slurry when the slurry contacts the wall, and further avoiding the scraper 4 from scraping and smoothing the unevenly distributed slurry, and the scraper 4 scraping the concentrated slurry too far and the scraping force on the slurry is too large, resulting in slurry overflowing and falling in the concentrated distribution area, and poor slurry smoothing effect in the area where the slurry is too little distributed.

[0021] As an embodiment of the present invention, the elastic sheets 33 are provided in multiple groups, and the elastic sheets 33 are independent of each other. A limiting rod 34 is also installed at the opening of the material storage trough 31, and the limiting rod 34 is located between the elastic sheet 33 and the scraper 4; The limit position of the elastic sheet 33 when it is deformed is limited by the limit rod 34, so as to avoid excessive deformation of the elastic sheet 33 after excessive squeezing of the material in the storage tank 31, which would cause uneven distribution of the slurry discharged from the discharge port 311 and affect the smearing effect of the smearing device on the wall. At the same time, because the elastic sheets 33 are independent of each other, when the elastic sheets 33 are squeezed and pushed by the mortar in the storage tank 31, the deformations of the elastic sheets 33 are independent of each other, so as to avoid the elastic sheets 33 driving each other and affecting the shielding effect of the elastic sheets 33 on the opening of the storage tank 31.

[0022] As an embodiment of the present invention, a connecting cavity 32 is provided in the mounting plate 3, and the slurry pump 12 delivers the slurry into the connecting cavity 32 through the delivery pipe 15; The communication cavity 32 is provided with a discharge port 321 connected to the material storage tank 31. The discharge ports 321 are provided in multiple groups and are evenly distributed in the material storage tank 31. By setting evenly distributed discharge ports 321 in the storage tank 31, the slurry entering the storage tank 31 can be relatively evenly distributed, avoiding the slurry being concentrated at a certain place in the storage tank 31, resulting in uneven distribution of the slurry at the discharge port 311 when it contacts the wall surface, affecting the effect of the smearing device on the wall surface, and affecting the flatness and quality of the surface decoration layer 71 on the wall surface; At the same time, the discharge port 321 is set to evenly distribute the slurry in the storage tank 31. When the slurry is discharged from the outlet, the slurry can be better and more easily affected by the elastic sheet 33, and further the slurry can evenly contact the wall surface from the discharge port 311, thereby improving the flatness and quality of the surface decoration layer 71 on the wall surface after smearing.

[0023] As an embodiment of the present invention, an elastic connection layer 41 is installed between the scraper 4 and the mounting plate 3, and the elastic connection layer 41 is divided into two parts on the upper and lower sides of the discharge port 311; By setting the elastic connecting layer 41, the scraper 4 and the wall surface can be buffered and deformed when in contact with each other, thereby improving the quality of the scraper 4 on the wall surface, ensuring the flatness and quality of the surface decoration layer 71 on the wall surface. At the same time, the elastic connecting layer 41 is set to support and fill the gap between the scraper 4 and the mounting plate 3 at the discharge port 311, ensuring that the slurry can smoothly contact the wall surface from the discharge port 311 on the scraper 4, thereby facilitating the scraper 4 to smooth the slurry on the wall surface.

[0024] As an embodiment of the present invention, the elasticity of the elastic connection layer 41 above the discharge port 311 is greater than that of the elastic connection layer 41 below the discharge port 311, and the thickness of the elastic connection layer 41 above the discharge port 311 is greater than that of the elastic connection layer 41 below the discharge port 311; Since the elasticity of the elastic connecting layer 41 above and below the discharge port 311 is inconsistent, the elastic force acting on the scraper 4 near the bottom is relatively small, thereby facilitating the slurry discharged from the discharge port 311 to move toward and be stored near the bottom, thereby cooperating with the movement of the scraper 4 from top to bottom, thereby improving the effect of smearing the wall and the flatness and quality of the wall after smearing.

[0025] As an embodiment of the present invention, a fixing frame 62 is installed on the lower surface of the bottom plate 1, a telescopic rod 61 is installed on the fixing frame 62, a shielding layer 6 is installed on the telescopic rod 61, and the shielding layer 6 is sleeved on the telescopic rod 61. The ends of the telescopic rod 61 and the shielding layer 6 away from the bottom plate 1 are in contact with the surface of the wall 7. When the smearing device applies the mortar to the wall, the telescopic rod 61 under the base plate 1 will also abut against the bottom of the wall. Through the shielding layer 6 made of plastic sleeved on the telescopic rod 61, an interception layer is set at the position of the wall 7 close to the ground, so as to intercept and collect the slurry that cannot be collected by the collecting plate 5 above, the contaminated slurry that rolls down the wall, and the mixed slurry that falls on the wall, so as to prevent the ground near the wall 7 from being contaminated and difficult to clean.

[0026] The specific workflow is as follows: After the wall 7 is built, the uneven parts of the wall 7 are polished and smoothed, and the corners and recesses of the wall 7 are filled and repaired. Then, the oil stains and floating dust on the wall 7 are cleaned, and the interface agent is subsequently rolled and brushed. After that, the staff prepares the mortar to be used, such as the bottom anti-cracking putty or the surface putty, and adds it to the paddle liquid cylinder in the paddle device. The mortar is evenly and evenly applied to the surface of the wall 7 through the paddle device, thereby completing the construction of the surface decoration layer 71; At the same time, during the construction process, the anti-alkali mesh cloth is pressed into the bottom anti-cracking putty layer and the surface putty layer, and the anti-alkali mesh cloths are connected and fixed to each other by fixing nails; At the same time, when plastering the wall, the mortar prepared by the staff is added into the slurry barrel, and then the staff pushes the plastering device to move to the wall to be constructed, so that the scraper 4 can be closely attached to the surface of the wall 7, and then the controller controls the motor 22 to run and drive the screw 21 to rotate, so that the scraper 4 moves to a high position, thereby plastering the wall from top to bottom; When applying mortar to the wall, the mortar pump 12 extracts mortar from the mortar barrel 11 through the connecting pipe 14, and then delivers the extracted mortar to the storage tank 31 through the delivery pipe 15, so that the mortar is covered on the wall from the outlet of the storage tank 31 and the outlet 311 on the scraper 4. After that, the mortar applying operation is completed as the scraper 4 moves. At the same time, the storage tank 31 opened on the mounting plate 3 allows the delivered mortar to be temporarily stored, and allows the mortar to fill the discharge port 311 on the scraper 4, so that the scraper 4 can evenly apply the mortar to the wall when smearing the wall. At the same time, when the scraper 4 applies the mortar to the wall, the mortar may overflow and drip downwards. The overflowing and dripping mortar is collected by the collecting plate 5 installed under the mounting plate 3. When the scraper 4 is wiping the wall from top to bottom, the collecting plate 5 located below the mounting plate 3 collects the slurry overflowing and falling from the scraper 4 and between the scraper 4 and the wall. At the same time, when the collecting plate 5 moves downward with the scraper 4, the contact roller 51 on the collecting plate 5 rotates counterclockwise, that is, the slurry dripping and close to the wall is gradually rotated to the collecting surface 53 of the collecting plate 5 as the contact roller 51 rotates; At the same time, the elastic deformation layer on the surface of the contact roller 51 allows the contact roller 51 to be closely attached to the wall surface, thereby avoiding a gap between the contact roller 51 and the wall surface. At the same time, the distance between the collecting surface 53 and the contact roller 51 is smaller than the thickness of the elastic deformation layer, so that the collecting surface 53 is closely attached to and squeezed on the elastic deformation layer, so that the slurry falling on the contact roller 51 can be fully scraped onto the collecting surface 53. At the same time, after the overflowed or dropped slurry is collected on the collecting plate 5, the slurry will flow under the action of the inclined collecting surface 53 and then contact the centralizing pipe 52. At this time, the recovery pump 13 on the bottom plate 1 will drive the recovery pipe 16 and the soft auger 521 in the centralizing pipe 52 to rotate, pushing the slurry contacting the centralizing pipe 52, so that the collected slurry can be taken away from the collecting plate 5 and returned to the slurry barrel 11. The opening of the material storage tank 31 is shielded by the elastic sheet 33, so that the mortar entering the material storage tank 31 needs to fill the material storage tank 31 or be evenly distributed in the material storage tank 31 before it can be discharged from the opening of the material storage tank 31, and then wait for the scraper 4 to evenly apply it to the wall surface. In this process, the elastic sheet 33 shields the opening, so that the slurry can be relatively evenly distributed to the opening of the material storage tank 31 as much as possible, and then when the slurry passes through the opening and contacts the wall surface, the slurry is relatively evenly distributed on the wall surface; The limit position of the elastic sheet 33 when deformed is limited by the limit rod 34, so as to prevent the elastic sheet 33 from being deformed too much after excessive extrusion of the material in the storage tank 31, resulting in uneven distribution of the slurry discharged from the discharge port 311. At the same time, since the elastic sheets 33 are independent of each other, when the elastic sheets 33 are squeezed and pushed by the slurry in the storage tank 31, the deformation of the elastic sheets 33 is independent of each other, so as to prevent the elastic sheets 33 from driving each other. By providing evenly distributed discharge ports 321 in the storage tank 31, the slurry entering the storage tank 31 can be relatively evenly distributed, thereby preventing the slurry from being concentrated in a certain place in the storage tank 31, resulting in uneven distribution of the slurry at the discharge port 311 when it contacts the wall surface; At the same time, the slurry is evenly distributed in the storage tank 31 through the provided discharge port 321. When the slurry is discharged from the outlet, the slurry can be better and more easily affected by the elastic sheet 33, and further the slurry is evenly contacted to the wall surface from the discharge port 311. The elastic connection layer 41 is provided to buffer and deform the scraper 4 when in contact with the wall surface. At the same time, the elastic connection layer 41 is provided to support and fill the gap between the discharge port 311 of the scraper 4 and the mounting plate 3, so as to ensure that the slurry can smoothly contact the wall surface from the discharge port 311 on the scraper 4. Since the elasticity of the elastic connection layer 41 above and below the discharge port 311 is inconsistent, the elastic force on the scraper 4 near the bottom is relatively small, so that the slurry discharged from the discharge port 311 is conveniently moved to and stored near the bottom, and then cooperates with the movement of the scraper 4 from top to bottom, thereby improving the effect of wiping the wall surface and the flatness and quality of the wall surface after wiping. When the smearing device applies the mortar to the wall, the telescopic rod 61 under the base plate 1 will also abut against the bottom of the wall. Through the shielding layer 6 made of plastic sleeved on the telescopic rod 61, an interception layer is set at the position of the wall 7 close to the ground, so as to intercept and collect the slurry that cannot be collected by the collecting plate 5 above, the contaminated slurry that rolls down the wall, and the mixed slurry that falls on the wall, so as to prevent the ground near the wall 7 from being contaminated and difficult to clean.
