Given the embodiments of the present invention, all other embodiments that can be obtained by a person of ordinary skill in the art without any inventive step are within the scope of the present invention.
As shown in FIG. 1, the construction method of the outer wall washed stone of the invention is suitable for the washed stone decoration and finishing construction of the outer wall of the building, in particular for the large-area decoration and finishing construction of the outer wall washed stone wall of the building. The construction method comprises the following construction steps:
step S100, basic layer processing: and plastering the outer wall of the building or brushing an interface agent to obtain the washed stone wall surface base layer.
Step S200, snapping: according to the design requirements of the building outer wall, a cellular/dripping seam is arranged on the building outer wall in a bouncing manner;

step S700, strip forming and pointing: and after the washed stone surface is naturally dried, taking out the dividing strips and the water dripping strips, and carrying out pointing treatment on the dividing seams and the water dripping seams by adopting cement fine sand mortar.
Specifically, in step S100, when performing the base layer processing:
(1) when the building outer wall is a brick base course, the building outer wall needs to be plastered to obtain the washed stone wall base course meeting the requirements. The plastering needs to reach the common standard of common plastering, and layered plastering is needed when the plastering thickness is more than or equal to 35 mm; the plastering surface is slightly rough and clean, the joint is smooth, the vertical surface verticality is not more than 4mm, the surface smoothness is not more than 4mm, the lines are straight, and the internal and external corners are square.
(2) When the building outer wall is a reinforced concrete base layer, plastering treatment or interface agent painting treatment can be selected for the building outer wall.
A. The operation of the plastering treatment of the reinforced concrete outer wall specifically comprises the following steps: firstly, chiseling the surface of concrete, removing the concrete with loose surface, brushing off dust by a steel wire brush, washing the concrete clean by clear water, and watering the concrete to be wet; then, 10% caustic soda water (namely sodium hydroxide solution) is used for brushing oil stains and dirt on the surface of the concrete, the concrete is washed by clear water and dried, and finally plastering operation is carried out until the plastering surface is firmly adhered to the concrete surface (namely, a plastering layer is not fallen off by hand), so that a water-washed stone wall base layer meeting the requirement is obtained, and the next procedure can be carried out.
B. The operation of brushing the interface agent on the reinforced concrete outer wall specifically comprises the following steps: and cleaning the surface of the reinforced concrete, airing, performing the processes of snapping the lines in the step S200 and adhering the dividing strips and dripping the water strips in the step S300, and then coating the interface agent. After the coating of the interfacial agent, the operation of brushing the cement paste in step S400 should be performed, and the interfacial agent should not be dried when brushing the cement paste. The interface agent is coated to realize the function of improving the surface performance of the reinforced concrete, so that the reinforced concrete meets the construction requirements of the subsequent procedures; the interface agent is coated when not dry, so that the water in the cement mortar can be prevented from being absorbed, the cement hydration effect of the cement mortar can be prevented from being influenced, meanwhile, the wet interface agent can promote the maintenance of the cement mortar layer, the strength development of the cement mortar layer is better, and the quality of the cement mortar layer is ensured.
When the base layer is plastered, the outer wall of the building is jointed with base layers made of different materials, and if the brick base layer is jointed with the reinforced concrete base layer, anti-cracking measures are taken at the joint.
The washed stone wall surface base layer obtained after the base layer treatment is finished needs to meet the requirements of slightly rough and clean surface and smooth joint; the verticality and the surface evenness of the vertical surface are not more than 4mm, the lines are straight, and the internal and external angles are square and regular.
In step S200, when the line snapping operation is performed:
if plastering treatment is adopted for the building outer wall base layer, line snapping operation is carried out after plastering treatment is finished and the obtained washed stone wall base layer has certain strength. The line snapping operation adopts ink fountain lines to pop up lattice/dripping seams, and the positions of the lattice/dripping seams are reasonably arranged according to the requirements of the lattice effect of the outer vertical surface of the building, the size of the wall surface, the positions of the convex and concave angles, the side lines of doors and windows and the like, or are arranged according to the special requirements of an owner; the position of the dividing/dripping seam is the position of the dividing strip and the dripping strip attached in the step S300. The lines of the grid/dripping seams are clear, do not flow and fall, are horizontal and vertical, and are pulled through at the same height or the same vertical position.
If the building outer wall is a reinforced concrete base layer and is treated by coating the interface agent, the line snapping operation can be carried out after the concrete surface is cleaned and dried.
In step S300, when the operation of attaching the division bar and the water dropping bar is performed:
continuously arranging separating strips or water dropping strips according to the mesh division/water dropping sewing lines arranged in the step S200, wherein the separating strips or the water dropping strips are not easy to fall off in the subsequent operation when being fixed, and meanwhile, the later peeling is convenient; can be fixed by small iron nails.
The effect of box strip is that wall deformation, fracture that prevent that later stage expend with heat and contract with cold and arouse makes the wall more have the stereovision simultaneously, and is more pleasing to the eye.
The water dropping strip is a measure for preventing rainwater from entering a balcony or flowing on glass when flowing downwards along the wall surface and is generally arranged at the junction of the bottom surface and the outer wall surface. The water-dripping-preventing window is suitable for parts with water-dripping-preventing requirements in building engineering, such as windowsills protruding out of an outer wall, window lintels, windows with openings not protruding out of the window, awning, balconies, parapet wall coping or waist lines protruding out of the outer wall. In the construction method, the water dripping strips are arranged at the positions of the cornice and the like, a water dripping line is formed outside the water dripping strips, rainwater is guided to drip along the lower edge of the water dripping line, the rainwater is prevented from permeating the wall, the wall is protected from being corroded by the rainwater, and the wall is prevented from being wet, leaked and mildewed.
The dividing strips and the water dropping strips can adopt thin wood strips or PVC plastic strips, and the cross section dimension is usually 10 multiplied by 10 mm. For example, the division bars and the water dropping bars are made of thin wood strips, and the division bars and the water dropping bars are fully soaked by water before use to ensure that the division bars and the water dropping bars are fully soaked by water so as to prevent the wall surface at the division seam/water dropping seam from cracking and hollowing due to the fact that the wood strips absorb water in the cement when the operation of brushing the cement layer in the step S400 is carried out.
The width and the depth of the grid strips are uniform, the joints are flat and straight, the fillet is neat, and the grid strips are horizontal and vertical. The water dripping strip is arranged at the cornice position and is located at the position, inwards extending 70-80 mm, of the cornice bottom.
Step S400, brushing cement mortar:
when the washed stone wall surface base layer is a plastering base layer, the washed stone wall surface base layer needs to be watered and moistened firstly, and cement mortar is scraped on the moistened washed stone wall surface base layer to form a cement mortar layer. Because the cement mortar is directly smeared on the dry washed stone wall base layer, moisture in the cement mortar can be sucked, the cement mortar is shrunk in volume due to the drying in the initial stage of the cement hydration action, cracks can easily appear, and after the cracks are generated, stress concentration is generated at the end parts of the cracks, so that the cracks can be further expanded, and the quality of a cement mortar layer is seriously influenced. After watering and wetting, the water in the cement mortar can be prevented from being absorbed, and meanwhile, the water in the base layer can also protect the cement mortar layer, so that the strength development is better, and the quality of the cement mortar layer is ensured. When the washing stone wall surface basic unit is the basic unit of plastering promptly, it is essential process that the cement paste of brushing will be preceding to the basic unit moist of watering.
When the outer wall of the building is made of reinforced concrete and the base layer of the washed stone wall surface is the interface agent to be coated, cement mortar is directly coated when the interface agent is wet, and watering and wetting are not needed.
The cement mortar layer has the function of better bonding the washed stone slurry with the washed stone wall base layer. The cement mortar should be scraped to fill the whole washed stone wall base layer, and the cement mortar should be rubbed and pressed back and forth to be scraped for three times during brushing, so that the surface is required to be flat, the thickness is uniform, and the thickness of the cement mortar layer is preferably 3-5 mm.
The cement mortar is formed by manually mixing cement and special rubber powder, and the proportion of the cement mortar is as follows: the weight ratio of cement to rubber powder is 5:1, and adding water and mixing. The glue powder can be 901 glue powder or rhizoma arisaematis and herba Lysimachiae Caprae Seu Ovis powder which are commercially available.
In one embodiment, step S400 further includes step S410, in which step S410 is to scrape the tooth marks, specifically, a trowel with a toothed edge is used to scrape uniform tooth marks on the rolled and scraped cement mortar layer, so as to facilitate better bonding between the cement mortar and the subsequent washed stone mortar, increase the contact area, and improve the adhesion strength.
In step S500, water washing stone slurry is smeared on the cement mortar layer, and the water washing stone slurry is prepared by mixing stones, cement and lime paste according to the weight ratio of 10: 5: 3, preparing, adding water and mixing by a stirrer. Wherein, the stones are the washing stones, the white marble is generally selected, the strength and hardness are required to be enough, the water absorption rate is low, the particle size is within the range of 4-6 mm, and the stones are polished into round corners by a ball mill. The stones are clear in color selection and free of variegated colors, and stones with different colors are mixed in proportion according to engineering decoration requirements. The lime paste is prepared by completely curing fine quicklime with water, and has the functions of ensuring the workability of the water-washed stone slurry and ensuring that the water-washed stone slurry has certain binding power.
The washed stone slurry is sequentially smeared from bottom to top, and is immediately kneaded, compacted, flattened by flattening, and processed in time at convex-concave positions, and locally loose parts are compacted by a trowel with a pointed front end. And (3) calendering the surface after kneading and compacting, flattening and compacting the smeared washed stone slurry, filling gaps with the spread stone slurry, extruding redundant air to form a compact washed stone slurry surface layer, and ensuring that the cement mortar layer and the washed stone slurry surface layer are tightly combined. The thickness of the stone washing slurry surface layer is slightly higher than the dividing strips by about 1mm, the thickness is 5-8 mm, and the surface layer is full and uniform and has a smooth surface.
Step S600, surface layer washing:
the surface washing is a key procedure of a stone washing construction method, the stone is washed too early or too excessive, stones are exposed out of a mortar surface and fall off easily, and the mortar cannot be washed cleanly after too late washing, so that the appearance is affected by surface dirt. Therefore, the surface layer is washed about 2 hours after the completion of the plastering and pressing of the water-washed stone slurry surface layer, the water-washed stone slurry surface layer is just initially set, namely, the surface layer is pressed by fingers without traces or is brushed by a brush without falling particles, which is the key for ensuring the washing quality.
When the washing machine is used for washing, the pressurized spray head of the hydraulic pump is used for spraying water from top to bottom in sequence for washing, the waterline of the pressurized spray head is scattered in a fan shape, the water pressure is controlled to be about 3-4 Mpa during washing, and the distance between the spray head and the wall surface is about 10-20 cm. And (3) washing the cement paste on the surface of the washed stone slurry surface layer to expose the washed stone, wherein the washed stone is exposed to 1/3-1/2 parts of the particle size, and the surface of the formed surface layer stone is preferably 2-3 mm higher than the surface of the cement paste. After the washing is finished under pressure, the cement laitance on the surface layer is washed by adopting non-pressure water flow to form a clean washed stone surface, so that the cement laitance is prevented from remaining on the surface of the washed stone, and the appearance is prevented from being influenced.
After the washing of the surface layer of the washed stone slurry is finished, the finished part of the washed stone surface is subjected to closed maintenance, so that construction cross contamination and collision damage are prevented.
If dry cement paste is found to be remained on the washed stone surface after maintenance is finished, oxalic acid solution can be adopted for cleaning clearly, and the oxalic acid solution is diluted and washed clean in time by clear water and is organically discharged into a sewer, so that the pollution to soil caused by flowing into a greening land block is avoided.
Cement mortar stuck on the door and window frame and the brick wall should be cleaned in time; the aluminum alloy door and window should be adhered with a protective film in time to prevent pollution.
Step S700, strip forming and pointing:
and naturally drying the washed stone slurry surface layer, and naturally air-drying the washed stone surface to obtain the grid strips and the water dropping strips after a certain strength is achieved, wherein the washing is usually carried out after three days of washing the washed stone slurry surface layer. The tools for lifting the grid strips and the water dropping strips comprise iron hooks, hammers and the like, and care should be taken to protect the washed stone surfaces at the grid strips and the water dropping strips from being damaged during lifting.
After the division strips and the water dropping strips are taken out, pointing can be carried out. Before pointing, the separation seam or the dripping seam is washed cleanly, and pointing treatment is carried out by adopting cement fine sand mortar. The cement fine sand mortar used for pointing is prepared from cement and fine sand according to the weight ratio of (11): 5, sieving fine sand; the mortar is prepared by adding water, and the consistency is that the pointing distillate is lifted and does not fall. The pointing seams are full, the surface layer is in a slightly concave arc shape, the lines are straight, and the wall surface cannot be polluted. After the pointing is finished, the wall surface is clean, neat and beautiful. The separating seam and the dripping seam after the pointing treatment have the mode functions.
And after pointing, water is sprayed for maintenance, the moisture is kept slightly wet, and the condition that the moisture is dissipated too fast until the surface layer is cracked, so that the construction quality is influenced is prevented.
The cement used in the construction method can adopt 42.5R early strength type ordinary portland cement, and if the temperature is higher, the early strength type cement can not be used. Before the cement is used in the field, the strength and stability of the cement should be tested in batches. The inspection batches are provided with the same serial numbers by the uniform manufacturers. The cement with different varieties and different strength grades can not be mixed.
In conclusion, the construction method for washing stone on the outer wall surface is suitable for washing stone to decorate a large-area building outer wall, and firstly, the outer wall is plastered or coated with an interfacial agent to form a washing stone wall surface base layer so that the roughness, the flatness, the cleanliness and the like of the wall surface meet the requirements of subsequent processes; secondly, snapping lines and laying dividing strips and dripping strips to form dividing seams and dripping seams on the subsequent stone slurry washing surface layer, wherein the dividing seams have the function of preventing the wall surface from deforming and cracking due to thermal expansion and cold contraction, and the dripping seams have the function of blocking dripping water, preventing rainwater from permeating the wall body, protecting the wall body from rainwater erosion and preventing the wall body from being wet, leaking and mildewing; watering and wetting the washed stone wall surface base layer, and scraping and brushing a cement mortar layer to increase the adhesion between the subsequent washed stone slurry surface layer and the wall body and prevent hollowing and shelling; then, brushing the surface layer of the water-washed stone slurry, and washing the surface layer to expose the water-washed stone to form a water-washed stone surface; and finally, drawing out the dividing strips and the water dripping strips, and carrying out pointing treatment on the dividing seams and the water dripping seams to form a neat and attractive water-washing stone wall surface.
