Specific embodiments

[0037] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0038] As Figures 1 to 9 shown, for the mortar plastering device and anti-cracking process for a building wall construction without plastering a masonry wall surface of the present invention, the anti-cracking process includes the following steps:

[0039] S1: Operate according to the masonry requirements using high-precision masonry, control the verticality and flatness of the masonry wall body 7 to be good, and then, roll-brush the interface agent on the surface of the wall body 7;

[0040] S2: Prepare the mortar, and use the mortar plastering device to plaster the mortar on the surface of the wall body 7 to form the surface decoration layer 71;

[0041] S3: After plastering the mortar on the wall body 7, hang alkali-resistant mesh cloth on the plastered wall surface;

[0042] Among them, the surface decoration layer 71 at least includes a bottom anti-cracking putty layer, a surface putty layer, and a decorative layer. In the S3 step, the alkali-resistant mesh cloth is pressed into the bottom anti-cracking putty layer and the surface putty layer, and the alkali-resistant mesh cloths are connected and fixed to each other by fixing nails;

[0043] Among them, in the S2 step, the mortar plastering device 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 scraping plate 4 is installed on the mounting plate 3, a storage tank 31 is opened on the mounting plate 3, a discharge port 311 is opened on the scraping plate 4, and the discharge port 311 communicates with the opening of the storage tank 31;

[0044] A slurry barrel 11 is installed on the bottom plate 1, and the mortar in the slurry barrel 11 is conveyed to the storage tank 31 through a slurry pump 12;

[0045] A collection plate 5 is installed below the installation plate 3. The collection plate 5 is in contact with the surface of the wall 7. The plastering device plasteres the wall surface from top to bottom through a scraper 4;

[0046] Among them, the fixing columns 2 on the bottom plate 1 are symmetrically arranged. Installation grooves are formed in the fixing columns 2, and screw rods 21 are rotatably installed in the installation grooves. A movable block 211 is installed on the screw rods 21. The screw rods 21 are driven by a motor 22 installed on the lower surface of the bottom plate 1, and the two screw rods 21 are synchronously rotated through a transmission structure;

[0047] 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 communicated through a conveying pipe 15, so as to stably and quantitatively convey the prepared mortar in the slurry barrel 11 to the storage tank 31;

[0048] Use high-precision building blocks to build the wall 7, so that the surface verticality and flatness of the wall 7 are good, and the surface of the wall 7 meets the quality standards of the decorative surface layer of the building wall 7, eliminating the need for a plastering layer, thereby achieving the purpose of reducing the construction cost by the anti-cracking agent;

[0049] After the wall 7 is built, the uneven places on the surface of the wall 7 are polished and leveled, and the missing corners and depressions on the wall 7 are filled and repaired to make the wall surface meet the flatness requirements. Then, the oil stains, floating ash, 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 subsequent rolling of the interface agent and ensures good brushing effect of the interface agent. Then, the staff prepares the mortar to be used, such as the bottom anti-cracking putty or the surface putty, adds it to the slurry barrel in the plastering device, and evenly and smoothly plasteres the mortar on the surface of the wall 7 through the plastering device, thereby completing the construction of the surface decoration layer 71;

[0050] At the same time, during the construction process, alkali-resistant fiberglass meshes are pressed into both the bottom anti-cracking putty layer and the surface putty layer. By using the stability of the structure of the alkali-resistant fiberglass meshes themselves, the structural strength of each putty layer after plastering is improved, and cracks on each putty layer are avoided. At the same time, since the alkali-resistant fiberglass meshes are connected and fixed to each other through fixing nails, the alkali-resistant fiberglass meshes in different putty layers are further interconnected and form a whole, improving the structural strength of the connection between each putty layer and between the putty layer and the surface of the wall 7, thereby performing anti-cracking reinforcement on the surface decoration layer 71 of the wall 7 surface and improving the anti-cracking effect of the wall surface;

[0051] Meanwhile, when plastering the wall surface, the mortar prepared by the staff is added to the slurry barrel. Then, the staff moves the plastering device to the front of the wall to be constructed, so that the scraper 4 can closely adhere to the surface of the wall 7. After that, the controller controls the motor 22 to operate and drive the screw 21 to rotate, so that the scraper 4 moves to a higher position, and then the wall surface is plastered from top to bottom;

[0052] When plastering the wall surface, the slurry pump 12 extracts the mortar from the slurry barrel 11 through the connecting pipe 14, and then sends the extracted mortar into the storage tank 31 through the delivery pipe 15, so that the mortar covers the wall surface from the outlet of the storage tank 31 and the discharge port 311 on the scraper 4. After that, as the scraper 4 moves, the plastering operation of the mortar is completed, making the plastered wall surface flat and smooth;

[0053] Meanwhile, the storage tank 31 opened on the mounting plate 3 enables the transported mortar to be temporarily stored, and enables the mortar to fill the discharge port 311 on the scraper 4. When the scraper 4 plasteres the wall surface, the mortar can be evenly plastered on the wall surface, ensuring that the surface finishing layer 71 on the wall surface is flat and uniform, and improving the construction quality of the surface finishing layer 71;

[0054] Meanwhile, when the scraper 4 plasteres the mortar on the wall surface, there will be a situation where the mortar overflows and drips downward. The collecting plate 5 installed below the mounting plate 3 collects the overflowing and dripping mortar, preventing this part of the slurry from falling to the ground and polluting the ground and the wall surface, increasing the difficulty of subsequent cleaning, and causing waste of mortar and increasing the construction cost.

[0055] As an implementation mode of the present invention, a contact roller 51 is installed at 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;

[0056] An elastic deformation layer is installed on the surface of the contact roller 51, and the distance between the collecting surface 53 of the collecting plate 5 for receiving the falling mortar and the contact roller 51 is less than or equal to the thickness of the elastic deformation layer;

[0057] A recycling pump 13 is installed on the bottom plate 1. The recycling pump 13 is connected to the slurry barrel 11 through a connecting pipe 14. A recycling pipe 16 is installed between the recycling pump 13 and the collecting plate 5. A collecting pipe 52 is installed on the collecting surface 53 of the collecting plate 5, and a flexible auger 521 is installed in the collecting pipe 52, and the flexible auger 521 extends into the recycling pipe 16;

[0058] When the squeegee 4 applies the slurry to the wall surface from top to bottom, the collecting plate 5 located below the mounting plate 3 collects the slurry that overflows and drops from between the squeegee 4 and the wall surface. At the same time, during the process of the collecting plate 5 moving downward together with the squeegee 4, the contact roller 51 on the collecting plate 5 will rotate counterclockwise, that is, as it rotates, the contact roller 51 gradually rotates the dripping slurry close to the wall surface onto the collecting surface 53 of the collecting plate 5, thereby improving the collection effect of the overflowing and dropping slurry and reducing the possibility of the slurry dripping onto the ground or adhering to the lower wall surface;

[0059] At the same time, through the elastic deformation layer on the surface of the contact roller 51, the contact roller 51 can be closely attached to the wall surface, avoiding the occurrence of gaps between the contact roller 51 and the wall surface, which may cause the dropped slurry to slide off from the gaps. 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 presses on the elastic deformation layer, further eliminating the gap between the contact roller 51 and the collecting surface 53, enabling the slurry falling on the contact roller 51 to be fully scraped onto the collecting surface 53, and avoiding the situation where the slurry comes into contact with the wall surface again or drips onto the ground as the contact roller 51 rotates, resulting in ground pollution, slurry waste, and subsequent difficult cleaning;

[0060] At the same time, when the overflowing 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 come into contact with the central pipe 52. At this time, the recovery pump 13 on the bottom plate 1 drives the rotation of the soft auger 521 in the recovery pipe 16 and the central pipe 52, pushing the slurry in contact with the central pipe 52, so that the collected slurry can be taken away from the collecting plate 5 and returned to the slurry barrel 11 again, in order 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 prevent the excessive amount of slurry on the collecting plate 5 from affecting the slurry collection effect.

[0061] As an implementation mode of the present invention, an elastic sheet 33 is installed at the opening of the storage tank 31, and the elastic sheet 33 shields the opening of the storage tank 31;

[0062] 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. Then, wait for the scraper 4 to evenly smear it on the wall surface. During this process, through the blocking of the opening by the elastic sheet 33, the slurry can be made to be distributed relatively evenly at the opening of the storage tank 31 as much as possible. Then, when the slurry passes through the opening and contacts the wall surface, the slurry is distributed relatively evenly on the wall surface, which is convenient for the scraper 4 to smear the slurry flat on the wall surface. It can avoid the situation that when the slurry contacts the wall surface, the slurry is unevenly distributed. Further, when the scraper 4 scrapes and smears the unevenly distributed slurry, the distance that the scraper 4 scrapes the concentrated slurry is too far and the acting force on the slurry is too large, resulting in the slurry overflowing and falling in the concentrated slurry distribution area, and the slurry smoothing effect is poor in the area where the slurry distribution is too little.

[0063] As an embodiment of the present invention, a plurality of groups of elastic sheets 33 are provided, and the elastic sheets 33 are independent of each other. A limiting rod 34 is also installed at the opening of the storage tank 31, and the limiting rod 34 is located between the elastic sheet 33 and the scraper 4;

[0064] The limiting position of the elastic sheet 33 when it deforms is restricted by the limiting rod 34, so as to avoid the elastic sheet 33 being deformed too much after being excessively squeezed by the material in the storage tank 31, resulting in uneven distribution of the slurry discharged from the discharge port 311, affecting the plastering effect of the plastering device on the wall surface. 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 mortar in the storage tank 31, the deformations between the elastic sheets 33 are independent of each other, avoiding the elastic sheets 33 driving each other and affecting the blocking effect of the elastic sheets 33 on the opening of the storage tank 31.

[0065] As an embodiment of the present invention, a communication cavity 32 is opened in the mounting plate 3, and the mortar pump 12 sends the mortar into the communication cavity 32 through the delivery pipe 15;

[0066] A discharge port 321 communicating with the storage tank 31 is opened on the communication cavity 32, and a plurality of groups of discharge ports 321 are provided, and the discharge ports 321 are evenly distributed in the storage tank 31;

[0067] By providing evenly distributed discharge ports 321 in the storage tank 31, the slurry entering the storage tank 31 can be distributed relatively evenly, avoiding the slurry concentrating at a certain place in the storage tank 31, resulting in uneven distribution of the slurry contacting the wall surface at the discharge port 311, affecting the plastering effect of the plastering device on the wall surface, and affecting the flatness and quality of the upper surface decoration layer 71 on the wall surface;

[0068] Meanwhile, through the discharge port 321 provided, the slurry is evenly distributed into the storage tank 31. When the slurry is discharged from the outlet, it 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, improving the flatness and quality of the surface finishing layer 71 on the wall surface after plastering.

[0069] 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.

[0070] Through the provided elastic connection layer 41, when the scraper 4 contacts the wall surface, it can buffer and deform, thereby improving the quality of the plastering on the wall surface by the scraper 4, ensuring the flatness and quality of the surface finishing layer 71 on the wall surface. At the same time, through the provided elastic connection layer 41, the gap between the discharge port 311 between the scraper 4 and the mounting plate 3 is supported and filled, ensuring that the slurry can smoothly contact the wall surface from the discharge port 311 on the scraper 4, and further facilitating the scraper 4 to level the slurry on the wall surface.

[0071] 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 the thickness of the elastic connection layer 41 below the discharge port 311.

[0072] Due to the inconsistent elasticity of the elastic connection layers 41 above and below the discharge port 311, the elastic force received by the scraper 4 near the lower part is relatively small, so that the slurry discharged from the discharge port 311 can move and be stored towards the lower part, and further cooperate with the downward movement of the scraper 4 from top to bottom, improving the effect of plastering the wall surface and the flatness and quality of the wall surface after plastering.

[0073] 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, the shielding layer 6 is sleeved on the telescopic rod 61, and 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.

[0074] When the plastering device applies the mortar to the wall surface, the telescopic rod 61 below the bottom plate 1 will also abut against the lower part of the wall surface. 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 to intercept and collect the slurry that cannot be collected by the collecting plate 5 above, the polluted slurry that rolls down from the wall surface, and the sundries mixed with the slurry that fall on the wall surface, avoiding the pollution and difficult cleaning of the ground near the wall 7.

[0075] The specific work process is as follows:

[0076] After the wall 7 is constructed, the uneven surface of the wall 7 is polished and leveled, and the corners and depressions of the wall 7 are filled and repaired. Then, the oil stains, floating ash, etc. on the surface of the wall 7 are cleaned. Subsequently, an interface agent is roller-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 slurry barrel in the plastering device. The mortar is evenly and smoothly plastered onto the surface of the wall 7 through the plastering device, thus completing the construction of the surface decoration layer 71;

[0077] Meanwhile, during the construction process, alkali-resistant fiberglass meshes are pressed into both the bottom anti-cracking putty layer and the surface putty layer. At the same time, the alkali-resistant fiberglass meshes are interconnected and fixed to each other by fixing nails;

[0078] Meanwhile, when plastering the wall surface, the mortar prepared by the staff is added to the slurry barrel. Then, the staff pushes the plastering device to move in front of the wall to be constructed, so that the scraper 4 can closely adhere to the surface of the wall 7. After that, the controller controls the operation of the motor 22 to drive the screw 21 to rotate, causing the scraper 4 to move to a higher position, thereby plastering the wall surface from top to bottom;

[0079] When plastering the wall surface, the slurry pump 12 extracts the mortar from the slurry barrel 11 through the connecting pipe 14, and then sends the extracted mortar into the storage tank 31 through the delivery pipe 15, so that the mortar covers the wall surface from the outlet of the storage tank 31 and the discharge port 311 on the scraper 4. After that, as the scraper 4 moves, the plastering operation of the mortar is completed;

[0080] Meanwhile, the storage tank 31 opened on the mounting plate 3 enables the transported mortar to be temporarily stored, and enables the mortar to fill the discharge port 311 on the scraper 4, so that when the scraper 4 plasteres the wall surface, the mortar can be evenly plastered onto the wall surface;

[0081] Meanwhile, when the scraper 4 plasteres the mortar onto the wall surface, there will be a situation where the mortar overflows and drips downward. The overflowing and dripping mortar is collected by the collecting plate 5 installed below the mounting plate 3;

[0082] When the scraper 4 plasteres the wall surface from top to bottom, the collecting plate 5 located below the mounting plate 3 collects the slurry that overflows and drops from between the scraper 4 and the wall surface. At the same time, during the process of the collecting plate 5 moving downward together with the scraper 4, the contact roller 51 on the collecting plate 5 will rotate counterclockwise, that is, as it rotates, the dripping slurry close to the wall surface is gradually rotated and brought closer to the collecting surface 53 of the collecting plate 5;

[0083] Meanwhile, through the elastic deformation layer on the surface of the contact roller 51, the contact roller 51 can closely adhere to the wall surface, preventing gaps from appearing 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 less than the thickness of the elastic deformation layer, causing the collecting surface 53 to closely adhere to and press on the elastic deformation layer, so that the slurry falling on the contact roller 51 can be fully scraped onto the collecting surface 53;

[0084] Meanwhile, 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 come into contact with the collecting pipe 52. At this time, the recovery pump 13 on the bottom plate 1 will drive the recovery pipe 16 and the flexible auger 521 in the collecting pipe 52 to rotate, pushing the slurry in contact with 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 again;

[0085] 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 apply it to the wall surface. During this process, by blocking the opening with the elastic sheet 33, the slurry can be made to be distributed relatively evenly at the opening of the storage tank 31 as much as possible. Then, when the slurry passes through the opening and contacts the wall surface, the slurry is distributed relatively evenly on the wall surface;

[0086] The limit position of the elastic sheet 33 when it deforms is restricted by the limit rod 34, preventing the elastic sheet 33 from being deformed too much after being excessively squeezed by the materials 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 mortar in the storage tank 31, the deformations of the elastic sheets 33 are independent of each other, preventing the elastic sheets 33 from driving each other;

[0087] By providing uniformly distributed discharge ports 321 in the storage tank 31, the slurry entering the storage tank 31 can be distributed relatively evenly, preventing the slurry from concentrating at a certain place in the storage tank 31, resulting in uneven distribution of the slurry when it contacts the wall surface at the discharge port 311;

[0088] Meanwhile, through the provided discharge ports 321, the slurry is evenly distributed 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, further enabling the slurry to evenly contact the wall surface from the discharge port 311;

[0089] Through the provided elastic connection layer 41, when the scraping plate 4 contacts the wall surface, it can buffer and deform. At the same time, through the provided elastic connection layer 41, the discharge port 311 is supported and filled in the gap between the scraping plate 4 and the mounting plate 3, ensuring that the slurry can smoothly contact the wall surface from the discharge port 311 on the scraping plate 4;

[0090] Due to the inconsistent elasticity of the elastic connection layer 41 above and below the discharge port 311, the elastic force acting on the scraping plate 4 near the lower part is relatively small, so that it is convenient for the slurry discharged from the discharge port 311 to move and store towards the lower part, and then cooperate with the downward movement of the scraping plate 4 to improve the effect of plastering the wall surface and the flatness and quality of the wall surface after plastering;

[0091] When the plastering device applies the mortar to the wall surface, the telescopic rod 61 under the bottom plate 1 will also abut against the lower part of the wall surface. 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 body 7 close to the ground to intercept and collect the slurry that cannot be collected by the collecting plate 5 above, the contaminated slurry rolling down from the wall surface, and the sundries mixed with the slurry falling from the wall surface, avoiding the pollution and difficult cleaning of the ground near the wall body 7.

[0092] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
