Description

Technical Field

[0001] The present application relates to the field of decoration and repair, and specifically to a house crack sealing, anti-seepage and waterproofing system and a process thereof. Background Art

[0002] There are three main ways that cracks form in houses: the first is cracks caused by thermal stress, the second is cracks caused by settlement, and the third is cracks caused by disasters such as earthquakes, typhoons, tsunamis, and impacts. Statistics show that cracks caused by settlement and various disasters only account for about 5% of the total, so the main cause of house cracks is still thermal stress.

[0003] Causes of cracks caused by temperature stress:

[0004] In summer, the outdoor circulation temperature can reach over 40 degrees Celsius. In summer, the roof surface is exposed to direct sunlight, and the roof temperature can reach around 65 degrees Celsius. In winter, the lowest outdoor circulation temperature is generally around -5 degrees Celsius. Therefore, the temperature difference between winter and summer can reach 70-80 degrees Celsius. Houses are generally composed of concrete and brickwork. The expansion coefficient of brickwork is only half that of concrete. Due to the mutual constraints between the house structures, coupled with temperature changes and the difference in the expansion coefficients of the two different materials, temperature internal stress is generated in the roof and walls. Because the expansion coefficient of the material is constant, the greater the temperature difference, the greater the internal stress generated. Therefore, when the internal stress generated in a part of the building exceeds the tensile and shear strength of the brickwork, the wall masonry will undoubtedly crack—that is, temperature cracks will appear.

[0005] Hazards of house cracks to building safety:

[0006] Although temperature cracks do not directly affect the safe use of the structure, if they are not handled and repaired in time, they will have a certain adverse effect on normal use, especially in cold areas. Rainwater penetrates into the structure through cracks and fissures in the house, causing freeze-thaw damage to the concrete, and even becoming a factor that turns building safety into unsafe. For example, it was found in the investigation that due to temperature cracks, the roof and walls are seriously leaking, causing many troubles for users. Some walls have water entering due to cracks, resulting in the peeling of wall plaster or finishing materials. Rainwater penetrates into the roof and walls and corrodes the building structure, endangering the safety of the building and surrounding pedestrians. (For example, in the early morning of June 24, 2021, a 12-story building in Florida, USA, collapsed vertically due to cracks in the building and long-term leakage and erosion of swimming pool water).

[0007] The existing treatment method is mainly to fill the cracks in the wall, but this method only treats the symptoms and not the root cause. After the filling is completed, the filling material in the cracks will still gradually degenerate under the erosion of the liquid. After a certain period of time, water seepage will still occur in the filled cracks, making it difficult to solve the water seepage problem at one time. Summary of the Invention

[0008] In response to the shortcomings of the existing technology, the present application provides a house crack sealing, anti-seepage and waterproofing system and process, which simplifies the process, improves the material formula, and reduces the difficulty of processing, so that ordinary people can complete the wall processing by themselves. At the same time, it can also better play the anti-seepage and waterproofing effect after treatment, and solve the problem of crack seepage at one time.

[0009] A house crack sealing, anti-seepage and waterproofing system includes a standard atlas, a process flow chart, a shovel, a hook rod, a high-speed micro-blower, a stirrer, a penetrating sand-fixing agent, powder, liquid, sealing twisted fiberglass cloth, a scraper, a brush, quartz sand, a grouting machine and a sandblasting machine that are used in conjunction with each other.

[0010] A process for sealing cracks in a house, preventing seepage and waterproofing, comprising the following steps:

[0011] (1) Determine the construction area based on the crack situation;

[0012] The construction area includes the crack and the area extending 10cm outward from the crack edge;

[0013] (2) Remove the wall surface in the construction area and remove the debris in the cracks;

[0014] (3) Blow away dust and water vapor from the wall and cracks;

[0015] (4) Inject a permeable sand-fixing agent into the cracks and on the surrounding walls to form a sand-fixing sealing layer;

[0016] (5) Preparation of functional slurry;

[0017] (6) Fill the cracks with the functional slurry and apply it on the sand-fixing sealing layer of the wall to form the first slurry layer;

[0018] (7) Lay the sealing fiberglass cloth on the first slurry layer;

[0019] (8) Apply the second layer of slurry on the sealed fiberglass cloth;

[0020] (9) Apply the third slurry layer on the second slurry layer.

[0021] The permeable sand-fixing agent described in step (4) is prepared by mixing methyl methacrylate and a diluent in a weight ratio of 3:7 to 4:6; the diluent is dichloromethane.

[0022] The functional slurry in step (5) is prepared by mixing a powder material and a liquid material, wherein the weight ratio of the powder material to the liquid material is 1.5:1 or 2:1;

[0023] The components of the liquid material and their weight parts are: 85 parts of acrylic emulsion, 0.15 parts of hydroxyethyl cellulose 250HBR, 14.3 parts of deionized water, 0.35 parts of NXZ defoamer, 0.1 parts of GT-50 preservative, and 0.1 parts of AMP-95;

[0024] The components of the powder and their weight parts are: 50 parts of Portland cement, 20 parts of glass flakes, 15 parts of quartz sand, 3 parts of silicon dioxide, and 12 parts of mineral fiber.

[0025] The particle size of the silicate cement is 0.2 mm, the particle size of the glass flakes is 0.005 mm, the particle size of the quartz sand is 0.5 mm, and the particle size of the silicon dioxide is 0.0003 mm.

[0026] The twist-sealed glass fiber cloth in step (7) is obtained by impregnating the glass fiber cloth with a diluted acrylate emulsion and drying it; the dried acrylate emulsion on the twist-sealed glass fiber cloth adheres to the periphery of all mesh holes on the twist-sealed glass fiber cloth, and the centers of all mesh holes on the glass fiber cloth are through holes; the diluted acrylate emulsion is prepared by mixing acrylate emulsion and water in a weight ratio of 3:7.

[0027] The second slurry layer in step (8) needs to completely cover all the through holes on the fiberglass cloth.

[0028] Filling the cracks in step (6) refers to injecting the functional slurry into the cracks by means of an injection device until the functional slurry overflows from the cracks, and brushing refers to applying the functional slurry on the sand-fixing sealing layer of the wall surface with a brush; and scraping in steps (8) and (9) refers to applying the functional slurry on the sealing fiberglass cloth or the second slurry layer with a scraper, in order to make the functional slurry more tightly bonded to the sealing fiberglass cloth or the second slurry layer.

[0029] In step (6), if there are weak parts of the building in the construction area, it is necessary to first apply the functional slurry 2-3 times on the sand-fixing sealing layer of the weak parts of the building, and then proceed to step (6) after the functional slurry is dry.

[0030] If a finishing material needs to be pasted after step (9), quartz sand needs to be sprayed on the surface of the third slurry layer before vitrification occurs. If a finishing material does not need to be pasted after step (9), putty and latex paint can be applied in sequence after the third slurry layer is dried.

[0031] The mesh number of the sprayed quartz sand is 80 mesh, and the quartz sand is sprayed by a sandblasting machine.

[0032] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0033] The present invention simplifies the process, improves the material formula, and reduces the difficulty of processing, so that ordinary people can complete the wall processing by themselves. At the same time, it can better play the anti-seepage and waterproof effect after processing, and solve the problem of water seepage in cracks at one time.

[0050] Example 1

[0051] A house crack sealing, anti-seepage and waterproofing system is characterized by comprising a standard atlas, a process flow chart, a shovel, a hook rod, a high-speed micro-blower, a stirrer, a penetrating sand-fixing agent, powder, liquid, sealed twisted fiberglass cloth, a scraper, a brush, quartz sand, a grouting machine and a sandblasting machine that are used in conjunction with each other.

[0052] Standard atlas such as Figure 5 、 6 As shown, it will display standard construction drawings for decoration and repair, so that users can construct according to the drawings. The standard drawing set is the existing technology in this field. Those skilled in the art can complete its setting and use without creative work, so it will not be described in detail here.

[0053] Process flow chart as follows Figure 7 As shown, its role is to let users complete the operation through the correct process flow, thereby better standardizing the processing process and ensuring the quality of the processed products.

[0054] Example 2

[0055] A process for sealing cracks in a house, preventing seepage and waterproofing, comprising the following steps:

[0056] (1) Determine the construction area based on the crack situation;

[0057] The construction area includes the crack and the area extending 10 cm outward from the edge of the crack.

[0058] (2) Remove the wall surface in the construction area and remove the debris in the cracks;

[0059] The wall can be scraped with a spatula, or you can choose the tool yourself according to the actual area of the construction area. For the subsequent construction effect, the wall should be scraped as clean as possible and the cracks should be cleaned.

[0060] (3) Blow away dust and water vapor from the wall and cracks;

[0061] This step generally involves first using a larger blowing tool to blow away the overall dust in the construction area, then using a brush to brush out the dust that is more firmly adhered to the walls and cracks, and finally using a blower or other blowing tool that can blow hot air to remove the remaining dust and overall water vapor.

[0062] (4) Inject a permeable sand-fixing agent into the cracks and on the surrounding walls to form a sand-fixing sealing layer;

[0063] The permeable sand-fixing agent is prepared by mixing methyl methacrylate and a diluent in a weight ratio of 3:7 to 4:6; the diluent is dichloromethane.

[0064] After spraying, the permeable sand fixation agent will penetrate into the cracks or gaps of building materials, and its penetration depth can reach 3-7mm. After the diluent evaporates, the methyl methacrylate will undergo polymerization and solidify into polymethyl methacrylate, which will complete the filling of the cracks and gaps in the building materials, effectively completing the blocking of channels through which water can penetrate.

[0065] (5) Preparation of functional slurry;

[0066] The functional slurry is formed by mixing powder and liquid, and the weight ratio of powder to liquid is 1.5:1 or 2:1. In order to avoid uneven stirring caused by manual stirring, the powder and liquid are poured into a container and stirred evenly by a stirrer, which better ensures the use effect of the functional slurry.

[0067] Among them, the weight ratio of powder and liquid in the functional slurry scraped on the sand-fixing sealing layer at the weak parts of the building is 2:1, and the weight ratio of powder and liquid in the functional slurry used in the first slurry layer, the second slurry layer and the third slurry layer is 1.5:1.

[0068] The components of the liquid material and their weight parts are: 85 parts of acrylic emulsion, 0.15 parts of hydroxyethyl cellulose 250HBR, 14.3 parts of deionized water, 0.35 parts of NXZ defoamer, 0.1 parts of GT-50 preservative, and 0.1 parts of AMP-95;

[0069] The components of the powder and their weight parts are: 50 parts of Portland cement, 20 parts of glass flakes, 15 parts of quartz sand, 3 parts of silicon dioxide, and 12 parts of mineral fiber.

[0070] The particle size of the silicate cement is 0.2 mm, the particle size of the glass flakes is 0.005 mm, the particle size of the quartz sand is 0.5 mm, and the particle size of the silicon dioxide is 0.0003 mm.

[0071] Portland cement is used as a gelling inorganic powder;

[0072] The glass flakes have a palace-style multi-layered structure, which makes them structurally impermeable and corrosion-resistant, and can be more effectively anti-corrosion, waterproof and anti-seepage;

[0073] The function of quartz sand is to resist pressure and wear;

[0074] The role of silica is to increase density and impermeability;

[0075] The role of mineral fiber is to improve crack resistance and density. In this application, the mineral fiber is selected from ceramic fiber, which has a needle-like structure, which can make the integrity of the coating better and make the adhesion between the inorganic powders tighter, thereby improving the "hydrophobicity" and "water pressure penetration resistance" of the coating.

[0076] The powder of the present application is graded by mixing inorganic powders of different particle sizes, especially the addition of glass flakes, so that after the construction of the waterproof coating, the glass flakes can be arranged in parallel and overlapping in the coating, thereby forming a flat palace-like structure with an aspect ratio of up to 30-120. The penetration of water in the cured coating must pass through countless tortuous paths, so the penetration distance in a certain thickness of the anti-seepage coating is greatly extended.

[0077] (6) Fill the cracks with the functional slurry and apply it on the sand-fixing sealing layer of the wall to form the first slurry layer;

[0078] Filling the cracks refers to injecting the functional slurry into the cracks through an injection device until the functional slurry overflows from the cracks, and brushing refers to applying the functional slurry on the sand-fixing sealing layer of the wall with a brush.

[0079] The functional slurry can be poured from a pointed container, injected with a syringe, or pumped in with a pump. The specific injection method needs to be selected based on the actual construction situation, so it will not be described in detail here.

[0080] In addition, a grouting machine can also be used for grouting. The specific structure of the grouting machine is as follows:

[0081] like Figure 1 As shown, the first grouting machine includes a water bottle 1 , a continuous injector 2 connected to the water bottle 1 , an adjustable handle 4 provided on the continuous injector 2 , and an injection head 3 connected to the continuous injector 2 .

[0082] The adjustable handle 4 is arranged below the continuous injector 2 .

[0083] The water bottle 1 is connected to the rear of the continuous injector 2 through a hose 5 .

[0084] The injection head 3 is connected to the front of the continuous injector 2 through a hose 5 .

[0085] The water bottle is a container with a larger capacity. Because it is connected with a hose, the user is allowed to carry the injection head and the continuous syringe in a larger range, which greatly improves the convenience of using the product and reduces the weight that the user needs to lift.

[0086] When using, first inject the filling material into the water bottle, then fix the water bottle to the back of the continuous syringe through a hose, then fix the hose connected to the injection head to the injection port of the continuous syringe, and then insert the injection head into the deepest part of the house crack that needs to be filled, and finally press the switch of the continuous syringe to allow the filling material to be squeezed into the hose and finally squeezed out of the injection head.

[0087] like Figure 2 As shown, the second grouting machine includes a water bottle 1, a continuous injector 2 connected to the water bottle 1, and an injection head 3 connected to the continuous injector 2.

[0088] The water bottle 1 is arranged below the continuous injector 2 .

[0089] The injection head 3 is connected to the front of the continuous injector 2 through a hose 5 .

[0090] When choosing a water bottle, you need to choose one made of hard material to avoid deformation of the bottle during use and better improve the grip of the product.

[0091] When in use, first inject the filling material into the water bottle, then fix the water bottle under the continuous syringe, then fix the hose connected to the injection head to the injection port of the continuous syringe, and then insert the injection head into the deepest part of the house crack that needs to be filled. Finally, press the switch of the continuous syringe to allow the filling material to be squeezed into the hose and finally squeezed out by the injection head.

[0092] like Figure 3 As shown, the third grouting machine includes a water bottle 1 and an injection head 3 connected to the water bottle 1.

[0093] The injection head 3 is connected to the water bottle 1 through a hose 5 .

[0094] When choosing a water bottle, you need to choose a water bottle made of soft material so that the water bottle can be squeezed and deformed by external force, and then the filling material inside can be squeezed out during squeezing.

[0095] When in use, first inject the filling material into the water bottle, then fix the hose connected to the injection head to the bottle mouth of the water bottle, then insert the injection head into the deepest part of the house crack that needs to be filled, and finally squeeze the water bottle so that the filling material is squeezed into the hose and finally squeezed out of the injection head.

[0096] If there are weak parts of the building in the construction area, it is necessary to first apply functional slurry 2-3 times on the sand-fixing sealing layer of the weak parts of the building, and then proceed to step (6) after the functional slurry is dry.

[0097] The weak points of a building mainly refer to the locations on the wall where holes or grooves are punched or where pipes, wires, etc. directly pass through.

[0098] (7) Lay the sealing fiberglass cloth on the first slurry layer;

[0099] The sealed twisted glass fiber cloth is obtained by impregnating the glass fiber cloth with diluted acrylate emulsion and drying it; the dried acrylate emulsion on the sealed twisted glass fiber cloth adheres to the periphery of all mesh holes on the sealed twisted glass fiber cloth, and the centers of all mesh holes on the glass fiber cloth are through holes; the diluted acrylate emulsion is prepared by mixing acrylate emulsion and water in a weight ratio of 3:7.

[0100] Since both the sealing fiberglass cloth and the functional slurry contain acrylic esters, the sealing fiberglass cloth and the second slurry layer can be more effectively integrated. The sealing fiberglass cloth integrated with the second slurry layer acts as a bracket, effectively improving the integrity of the wall coating.

[0101] By setting up sealed twisted fiberglass cloth, the various materials in the construction area can be more integrated after drying, making them more firmly fixed to the wall, and effectively avoiding the situation where some materials fall off the wall.

[0102] Compared with the sealed twisted glass fiber cloth used in this application, the defects of the non-woven fabric used in the prior art are that it is not resistant to corrosion and has weak support. The defects of the ordinary glass fiber cloth used in the prior art are that it has poor fusion with the coating covering the glass fiber cloth, and cavities are easily formed, which affects the overall coating effect.

[0103] (8) Apply the second layer of slurry on the sealed fiberglass cloth;

[0104] The second slurry layer needs to completely cover all the through holes on the fiberglass cloth.

[0105] (9) Apply the third slurry layer on the second slurry layer.

[0106] Scraping refers to the use of a scraper to apply the functional slurry on the sealing fiberglass cloth or the second slurry layer, the purpose of which is to make the functional slurry more tightly bonded to the sealing fiberglass cloth or the second slurry layer.

[0107] If no finishing material is required after step (9), then putty and latex paint can be applied in sequence after the third slurry layer is dry.

[0108] Example 3

[0109] The only difference between this embodiment and embodiment 1 is that, if a finishing material needs to be pasted after step (9), quartz sand needs to be sprayed on the surface of the third slurry layer before vitrification occurs.

[0110] The mesh number of the sprayed quartz sand is 80 mesh, and the quartz sand is sprayed by a sandblasting machine.

[0111] Spraying quartz sand can better improve the fulcrum between the finishing material and the wall, and improve the firmness of the finishing material adhesion.

[0112] like Figure 4 As shown, a sandblasting machine includes a handheld structure, a micro blower 104 arranged on the handheld structure, and a material bin 111 arranged on the handheld structure.

[0113] The silo can be made of a bottle with a threaded opening, which can be inverted and fixed to the handheld structure through the threaded opening so that the quartz sand in the threaded opening can fall downward under the action of gravity. The mesh size of the quartz sand should be greater than 80 mesh to ensure that the micro fan can blow it out normally.

[0114] The handheld structure consists of a front power storage handle 109 , a mixing chamber 106 arranged on the front power storage handle 109 , an air duct 105 passing through the mixing chamber 106 from front to back, and a rear handle 102 connected to the air duct 105 .

[0115] The front power storage handle contains a rechargeable power source, which has two functions: one is to provide a gripping mechanism for people to operate, making the device easier to hold; the other is to power the micro blower so that the product can be used when there is no external power supply, thereby improving the flexibility of the product.

[0116] The air duct 105 is connected to the mixing chamber 106; a charging port 108 connected to a front power storage handle 109 is provided on the side wall of the mixing chamber 106.

[0117] The charging power supply can be charged through the charging port. This technology is existing technology. Those skilled in the art can complete its setting and use without creative work, so it will not be described in detail here.

[0118] The front end of the air duct 105 is further provided with a nozzle 110 that matches the air duct 105 .

[0119] The function of the nozzle is to adjust the coverage area and coverage rate per unit area of the sprayed quartz sand through different openings, so as to meet the different static friction forces required by different finishing materials.

[0120] The front end side surface of the rear handle 102 is fixed to the side surface of the air duct 105, and the rear handle 102 is "L"-shaped.

[0121] The rear handle is designed in an L shape, which is more convenient for users to hold and control.

[0122] The rear handle 102 is provided with a switch 3 which is electrically connected to the front power storage handle 109 and is used to control the micro fan 104 .

[0123] The switch allows users to more easily control the opening and closing of the micro fan, further improving the convenience of product use.

[0124] The air outlet of the micro fan 104 is connected to the end of the air duct 105 .

[0125] The silo 111 is inverted above the mixing silo 106 , and the silo 111 is communicated with the mixing silo 106 ; the mixing silo 106 is provided with a sand inlet 107 communicated with the mixing silo 106 .

[0126] An adjustable feed valve can also be set at the sand inlet to further increase the amount of sand blasting by controlling the opening and closing degree of the feed valve, thereby improving the controllability of the product.

[0127] It should be noted that the silo is only provided with one opening for discharging materials, the purpose of which is to prevent wind from leaking out of the silo, thereby ensuring the effect of product discharging.

[0128] A support base 101 is further provided at the lower end of the rear handle 102 , and the bottom surface height of the support base 101 is the same as the bottom surface height of the front power storage handle 109 .

[0129] The purpose of setting the support base is to facilitate the product to be placed directly on the ground.

[0130] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0131] Furthermore, the above-described specific embodiments are merely illustrative. Persons skilled in the art may devise various solutions based on the disclosure of the present invention, and such solutions fall within the scope of the present invention and are intended to be protected by the present invention. Persons skilled in the art should understand that the present description and drawings are intended to be illustrative and not to limit the scope of the claims.
