[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0044] Combine the following Figures 1 to 5 , describing an embodiment of the present invention.

[0045] According to an embodiment of the present invention, there is provided an exterior wall plastering construction process, comprising the following steps:

[0046] Step 101: Perform base treatment on the wall 1.

[0047] In the embodiment of the present invention, the base layer of the wall 1 is processed to increase the adhesion of the surface of the wall 1 and improve the firmness and stability during plastering.

[0048] Step 102: hang a plumb line on the wall 1 and paste mortar cakes.

[0049] In the embodiment of the present invention, a plumb line is used to determine the thickness of the plastering, and plaster cakes are set to control the thickness of the plastering during plastering, thereby ensuring the flatness and verticality of the wall surface.

[0050] Step 103, setting different reinforcement measures on the wall 1 according to the plaster thickness of the wall 1;

[0051] In an embodiment of the present invention, different reinforcement measures are provided on the wall 1 according to the plaster thickness of the wall 1 to improve the structural strength and integrity after plastering, so that the internal stress of the plaster layer is evenly distributed, reducing cracking, hollowing and falling risks.

[0052] Step 104, layered plastering;

[0053] In the embodiment of the present invention, a layered plastering method is adopted, preferably 1:3 cement mortar is used for layered plastering, with a thickness of 20 mm for each layer, and each layer is flush with the ash cake, and is scraped flat and straight with a large bar, and rubbed with a wooden trowel, so that the surface after plastering is flat, clean, smooth and refreshing, thereby improving the plastering effect.

[0054] Step 105: Maintain the plastered wall 1.

[0055] In the embodiment of the present invention, after the plastering is completed, the surface layer needs to be cured to shape the plaster layer and improve the shaping effect. Specifically, watering can be used for curing, and the curing time is greater than or equal to three days to ensure the shaping effect.

[0056] In the embodiment of the present invention, firstly, the base layer of the wall 1 is treated to improve the adhesion of the base layer and ensure the firmness and stability after plastering. Then, a plumb line is hung on the cavity and a plaster cake is pasted to ensure the accuracy of the plastering thickness and the flatness and verticality of the wall after plastering. Then, different reinforcement measures are arranged on the wall 1 according to the plastering thickness of the wall 1 to facilitate hanging plaster. At the same time, the formed plastering layer is supported to improve the firmness and integrity of the plastering layer, so that the internal stress of the plastering layer is evenly distributed, reducing cracking, hollowing and falling risks. Then, layered plastering is carried out to improve the plastering effect. Finally, the wall 1 after plastering is maintained to improve the molding effect.

[0057] Specifically, before step 101, a scaffold is also set up to facilitate the construction.

[0058] Specifically, before step 104, a mortar receiving plate is provided below the corresponding plastering position on the erected rack, and the mortar dropped from the upper part or hung from the large bar falls directly onto the mortar receiving plate, thereby preventing excess mortar from falling directly on the ground and being difficult to recover.

[0059] Specifically, each time plastering is completed, the mortar on the mortar board will be recycled. If it cannot be reused, it must be cleaned up in time and transported to the designated garbage dump.

[0060] In one embodiment, step 101 specifically includes the following sub-steps:

[0061] Step S101, the positions of the mold running and the mold bursting on the surface of the wall 1 are cut and punched to a preset size.

[0062] In the embodiment of the present invention, the positions of the mold running and the mold bursting on the surface of the wall 1 are chiseled to preset sizes to improve the flatness and uniformity of the surface of the wall 1 so as to facilitate plastering or setting reinforcement measures.

[0063] Step S102: taking preset measures to process the surface of the wall 1 after the punching.

[0064] In the embodiment of the present invention, according to the surface condition of the wall 1 after beating, pre-set measures are taken to clean the surface of the wall 1, which can improve the bonding strength between the surface of the wall 1 and the plaster layer and the uniformity of bonding.

[0065] Step S103, water the surface of the wall 1 to moisten it, and apply 108 glue cement slurry bonding layer.

[0066] It should be noted that the 108 glue and cement are mixed together and then evenly sprayed onto the wall surface by machine to form a 108 glue cement slurry bonding layer. The burr length should not be greater than 8mm.

[0067] In the embodiment of the present invention, by applying 108 glue cement slurry bonding layer, the bonding strength of the base layer of the wall 1 is improved, and then the bonding strength between the plaster layer formed by plastering and the base layer of the wall 1 is improved, effectively preventing problems such as cracking and bubbling, making the wall surface smoother and smoother, and playing a waterproof role.

[0068] Step S104, after the adhesive layer of the glue cement slurry 108 solidifies, water is sprinkled for curing within a preset time.

[0069] In the embodiment of the present invention, by sprinkling water and curing within a preset time, the 108 glue cement slurry bonding layer reaches a relatively high strength and is firmly adhered to the base layer of the wall 1.

[0070] In one embodiment, step 102 specifically includes the following sub-steps:

[0071] When the surface of the wall 1 is leaking reinforcement, anti-rust paint and plain cement slurry are applied to the leaking part, and then cement mortar is used to smooth and compact it.

[0072] It should be noted that cement mortar can be made of 1:2 cement mortar.

[0073] In the embodiment of the present invention, anti-rust paint and plain cement slurry are applied together, and then cement mortar is used to smooth and compact the surface to hide the leaking reinforcement, prevent the leaking reinforcement from rusting, and make the surface smooth.

[0074] When there is oil stain on the surface of the wall 1, the oil stain is removed by using caustic soda solution, and then the caustic soda solution is rinsed clean with clean water and dried.

[0075] In the embodiment of the present invention, caustic soda solution is used to remove oil stains to improve the cleanliness of the base layer of the wall 1. Preferably, the caustic soda solution is 10% caustic soda solution.

[0076] When there is a screw rod hole on the surface of the wall 1, 20mm-30mm is removed from both sides of the screw rod hole, and the screw rod in the screw rod hole is sealed with a foaming agent. The removed parts at both ends of the screw rod hole are smoothed and compacted with cement mortar, and polypropylene is used to paste on the surface of the wall 1.

[0077] In the embodiment of the present invention, 20mm-30mm is removed from both sides of the screw rod hole, and a foaming agent is used to seal the screw rod in the screw rod hole. The removed parts at both ends of the screw rod hole are smoothed and compacted with cement mortar, and polypropylene is used to paste on the surface of the wall 1 to improve the repair effect. Preferably, the weight of the polypropylene is 200g and the range is 100mm*100mm to ensure the structural strength after repair.

[0078] In one embodiment, step 103 specifically includes the following sub-steps:

[0079] Step S301: Draw a control line on the top surface of the parapet.

[0080] Step S302: measure according to the control line, and hang a vertical line from top to bottom with a thin line at the preset position. It should be noted that the preset position is a corner, a wall buttress, a large wall surface, etc., and the vertical line must be hung from top to bottom, and the vertical line cannot be hung in sections to ensure the accuracy of the hanging vertical line.

[0081] Step S303, determine the plastering thickness according to the hung vertical line, and draw the horizontal line to paste the plaster cakes.

[0082] Preferably, the size of the ash cakes is 50 mm square, and the distance between the ash cakes is 1.5 m.

[0083] In one embodiment, step 104 specifically includes:

[0084] When the plaster thickness is less than or equal to 35 mm, multiple first fixing members are used to embed the reinforcement and adhere it to the wall 1 in a plum blossom arrangement, and the first steel wire is fixed to the surface of the wall 1 through the first fixing members, and is fixed by a patch at the same time.

[0085] In an embodiment of the present invention, a first fixing member is used to embed reinforcement on the wall 1 in a plum blossom arrangement to improve stability, and then the first steel wire mesh is fixed by the first fixing member so that plaster can be hung during plastering. After the plastering is completed, the integrity of the plaster layer is enhanced to improve stability, so that the plaster layer can better adapt to the deformation and settlement of the wall 1, thereby reducing the risk of cracking caused by uneven settlement. At the same time, the stress distribution inside the plaster layer is made more uniform, effectively avoiding cracking caused by stress concentration. The toughness of the first steel wire mesh can also absorb and disperse part of the stress, further reducing the risk of cracking.

[0086] Specifically, the first fixing member is a cement nail, through which the first steel wire mesh is tightly connected to the wall 1, ensuring a tight fit between the plaster layer and the wall 1, reducing hollowing and falling problems, and improving the quality and stability of the plaster layer.

[0087] In one embodiment, Figure 2and Figure 3 As shown, step 104 specifically includes:

[0088] When the plaster thickness is greater than 35 mm and less than or equal to 50 mm, multiple second fixing members 2 are used to embed the reinforcement and adhere it to the wall 1 in a plum blossom arrangement. A second steel mesh 3 is set on the surface of the wall 1 through the second fixing members 2, and a third steel mesh 4 is set 135 mm away from the wall.

[0089] In an embodiment of the present invention, the second fixing member 2 is used to embed the reinforcement on the wall 1, and the plum blossom arrangement is adopted to improve the stability. The second steel wire mesh 3 is then fixed by the second fixing member 2, and a third steel wire mesh 4 is added at a distance of 135 mm from the wall to avoid cracking or deformation caused by excessive plaster thickness so that the plaster can be hung during plastering. After the plastering is completed, the integrity of the plaster layer is enhanced to improve the stability, so that the plaster layer can better adapt to the deformation and settlement of the wall 1, thereby reducing the risk of cracking caused by uneven settlement. At the same time, the stress distribution inside the plaster layer is made more uniform, effectively avoiding cracking caused by stress concentration. The toughness of the second steel wire mesh 3 and the third steel wire mesh 4 can also absorb and disperse part of the stress, further reducing the risk of cracking.

[0090] Specifically, the second fixing member 2 is a steel bar with a diameter of 8 mm.

[0091] In one embodiment, Figure 4 and Figure 5 As shown, step 104 specifically includes:

[0092] When the plaster thickness is greater than 50mm and less than or equal to 100mm, multiple third fixings 5 ​​are used to embed the reinforcement and adhere it to the wall 1 in a plum blossom arrangement. A fourth steel mesh 6 is set on the surface of the wall 1 through the third fixings 5, a steel mesh 7 is set at 135mm from the wall, and a fifth steel mesh 8 is set at 150mm from the wall.

[0093] It should be noted that after installing the steel mesh, the fourth steel mesh and the fifth steel mesh, the interfaces and edges between the meshes need to be processed, and screws are used to penetrate the meshes and firmly fix them to the wall structure or the reserved fixing points. For the intersection of the two structures and other parts that particularly require high strength and durability, the joints between the steel mesh and the fourth steel mesh and the fifth steel mesh are welded.

[0094] In an embodiment of the present invention, the third fixing member 5 is used to embed reinforcement on the wall 1, and a plum blossom arrangement is adopted to improve stability. The fourth steel mesh 6 is then fixed by the third fixing member 5, and a steel mesh 7 and a fifth steel mesh 8 are additionally provided. The steel mesh 7 can be welded to the third fixing member 5, and the steel mesh 7 is arranged between the third steel mesh 4 and the fifth steel mesh 8 to improve the overall support strength, ensure balanced force, avoid cracking or deformation caused by excessive plaster thickness, and facilitate plaster hanging during plastering. After the plastering is completed, the integrity of the plaster layer is enhanced to improve stability, so that the plaster layer can better adapt to the deformation and settlement of the wall 1, thereby reducing the risk of cracking caused by uneven settlement, and at the same time making the stress distribution inside the plaster layer more uniform, effectively avoiding cracking caused by stress concentration, and the toughness of the fourth steel mesh 6, the steel mesh 7 and the fifth steel mesh 8 can also absorb and disperse part of the stress, further reducing the risk of cracking.

[0095] Specifically, the third fixing member 5 is a steel bar with a diameter of 8 mm.

[0096] Specifically, the diameter of the steel wires in the first steel mesh is 2 mm.

[0097] Specifically, the diameter of the steel wires in the second steel mesh 3 is 2 mm.

[0098] Specifically, the diameter of the steel wires in the third steel mesh 4 is 2 mm.

[0099] Specifically, the diameter of the steel wires in the fourth steel mesh 6 is 2 mm.

[0100] Specifically, the diameter of the steel wires in the fifth steel mesh 8 is 2 mm.

[0101] Specifically, the first steel mesh, the second steel mesh 3, the third steel mesh 4, the fourth steel mesh 6 and the fifth steel mesh 8 are all galvanized steel meshes to increase their service life.

[0102] In one embodiment, the spacing of the plum blossom arrangement is 200 mm*500 mm.

[0103] In the embodiment of the present invention, the stability of the overall structure is ensured by adopting the plum blossom arrangement.

[0104] In one embodiment, the plaster thickness is less than or equal to 30 mm each time.

[0105] In the embodiments of the present invention, it is avoided that the thickness is too large and it is difficult to dry, resulting in poor stability and molding effect of the plaster layer.

[0106] In the embodiment of the present invention, different reinforcement measures are adopted according to the thickness of the plaster to enhance the integrity of the plaster layer, reduce the risk of cracking, reduce the risk of hollowing and falling off, make the overall appearance more beautiful and coordinated, and avoid cracking of the surface layer.
