Abstract
Description
Technical Field
[0001] The invention belongs to the field of building construction, and particularly relates to a thin-film (5-8 mm) construction process. Background Art
[0002] In the process of building bonding construction, the choice of bonding process and the use of construction tools directly affect the bonding effect and project quality. The spatula commonly used in the industry is the square-tooth spatula, which has a square edge. The general square-tooth spatula specification is a tooth side length of 12mm (such as Figure 1 For a long time, construction workers have generally used square-toothed trowels to apply coatings to building substrates (such as walls and floors) and building materials (such as tiles and rock slabs).
[0003] However, this traditional construction method has obvious drawbacks. Figure 2 As shown in the figure, when scraping vigorously with a square-toothed spatula, the contact area between the adhesive material and the back of the tile / slab is only 50%. This means that during the subsequent installation of the tile / slab on the wall, insufficient kneading and uneven material distribution can easily lead to loose adhesion between the tile / slab interface and the base layer interface with the adhesive material, making it impossible to ensure full adhesion. This in turn reduces effective adhesion, increases the risk of tile / slab falling off, and affects the safety and durability of the building.
[0004] Traditional construction methods also struggle to meet thin-film requirements. Due to the tooth design and specifications of square-tooth trowels, the resulting application often results in thicker layers, failing to meet thin-film requirements. With the development of the construction industry, thin-film applications are gaining popularity due to their advantages, such as material savings and reduced space usage. The limitations of traditional construction methods in this regard are becoming increasingly apparent.
[0005] In addition, from the perspective of construction efficiency and labor intensity, the square-toothed trowel has a larger contact area with the ceramic tiles / rock slabs during use, and the resistance during scraping is greater, which requires the construction worker to expend more effort, which not only increases the labor intensity, but also reduces the construction efficiency to a certain extent.
[0006] In summary, the traditional square toothed spatula construction process has many problems in terms of full adhesion rate guarantee, thin patch realization and construction efficiency, and needs to be improved. Based on this, the present invention proposes a new thin patch construction process technology solution. Summary of the Invention
[0007] In order to solve the problems existing in the prior art, the present invention provides a thin-film pasting construction process, which includes the following steps: (1) using a trowel to press and scrape the adhesive material on the building base, and then using the trowel again and pressing and scraping the adhesive material at an angle of 45-60° with the building base; (2) also using a trowel to press and scrape the adhesive material on the building material, and then using the trowel again and pressing and scraping the adhesive material at an angle of 45-60° with the building material; (3) the pressed and scraped building base and the pressed and scraped building material are attached.
[0008] Preferably, in step (1), the building base is a building wall or a building floor. Building walls and floors are the most important pasting bases in buildings, and the process is suitable for these two bases, expanding the application range of the process.
[0009] Preferably, in step (1) or / and step (2), the trowel is a triangular sawtooth trowel or a square tooth trowel. The triangular sawtooth trowel is shown in Figure 3 , the edge is triangular, and the specifications of a general triangular sawtooth trowel are: tooth height, tooth width 3mm, and triangular edge length 3.35mm. As shown in Figure 4 , when the triangular sawtooth trowel is used to scrape the adhesive material on the back of the building material (such as ceramic tile / rock plate), the contact between the pasting material and the pasting interface on the back of the building material is 100%, and the effective contact area ensures effective adhesion.
[0010] Preferably, in step (1) or / and step (2), the adhesive material is a cement-based adhesive. As a commonly used adhesive material, the cement-based adhesive has the advantages of wide source, low cost, stable adhesion performance, etc., and the selection of the cement-based adhesive as the adhesive material is conducive to the popularization and application of the process. In addition, the cement-based adhesive of the present application meets the relevant contents of the building material industry standard JC / T 547-2017.
[0011] Preferably, in step (2), the building material is ceramic tile or rock plate. Ceramic tile and rock plate are commonly used materials in building decoration, and the process is designed for these two materials, which has strong practicality.
[0012] Preferably, the thin pasting construction process comprises the following steps: (1) using a triangular sawtooth trowel to press and scrape the adhesive material on the building base, and then using the triangular sawtooth trowel again and pressing and scraping the adhesive material at an angle of 45° with the building base; (2) also using a square tooth trowel to press and scrape the adhesive material on the building material, and then using the square tooth trowel again and pressing and scraping the adhesive material at an angle of 45° with the building material; (3) the pressed and scraped building base and the pressed and scraped building material are attached.
[0013] Preferably, the thin-pasting construction process comprises the following steps: (1) using a triangular serrated trowel to press and scrape the bonding material on the building base, and then using the triangular serrated trowel again to press and scrape the bonding material at an angle of 60° with the building base; (2) using a square serrated trowel to press and scrape the bonding material on the building material at the same time, and then using the square serrated trowel again to press and scrape the bonding material at an angle of 60° with the building material; (3) the pressed and scraped building base and the pressed and scraped building material are pasted together.
[0014] Preferably, the thin-pasting construction process comprises the following steps: (1) using a triangular serrated trowel to press and scrape the bonding material on the building base, and then using the triangular serrated trowel again to press and scrape the bonding material at an angle of 45° with the building base; (2) using a square serrated trowel to press and scrape the bonding material on the building material at the same time, and then using the square serrated trowel again to press and scrape the bonding material at an angle of 60° with the building material; (3) the pressed and scraped building base and the pressed and scraped building material are pasted together.
[0015] Preferably, the thin-pasting construction process comprises the following steps: (1) using a triangular serrated trowel to press and scrape the bonding material on the building base, and then using the triangular serrated trowel again to press and scrape the bonding material at an angle of 60° with the building base; (2) using a square serrated trowel to press and scrape the bonding material on the building material at the same time, and then using the square serrated trowel again to press and scrape the bonding material at an angle of 45° with the building material; (3) the pressed and scraped building base and the pressed and scraped building material are pasted together.
[0016] During the construction process, the following operations also need to be strictly paid attention to: (i) base treatment: before construction, the building base must be fully treated, the surface of the base should be flat, clean, dry, free of oil stains, dust, loose materials, etc., and for uneven bases, leveling treatment is needed to ensure the flatness of the surface of the pasted building material.
[0017] (ii) bonding material preparation: when using cement-based adhesive as the bonding material, it must be prepared strictly according to the specified ratio to ensure the stability of the performance of the bonding material, and the prepared bonding material should be used within the specified time to avoid affecting its bonding force due to long time.
[0018] (iii) Trowel usage specifications: When using triangular serrated trowels and square serrated trowels, pay attention to the correct usage method, the angle between the trowel and the base layer or building material should be controlled within 45-60°, the pressure scraping force should be uniform, avoid excessive or insufficient force, and regularly check the serration of the trowel, replace it in time if damaged, to ensure the construction quality.
[0019] (iv) Key points of lamination operation: When laminating the pressed and scraped building base and building material, ensure the accurate position of the two, avoid misalignment, and after lamination, adjust and compact the building material appropriately, make the adhesive material fully contact with the base and building material, and discharge air to improve the full adhesive rate.
[0020] (v) Maintenance and inspection: After lamination, maintain the bonded area, avoid external impact or vibration during maintenance, ensure that the adhesive material can fully solidify, and after maintenance, check the bonding quality, check for air pockets, peeling and other phenomena, and handle them in time if there are problems.
[0021] In addition, this construction process also has good expansibility: (i) Application of different base materials: In addition to common building walls and floors, this process can also be applied to other types of base materials such as gypsum board base and concrete base after appropriate adjustment. For different base materials, the ratio of adhesive material and construction operation steps should be adjusted reasonably according to the surface characteristics and strength to ensure the bonding effect.
[0022] (ii) Application in special environments: In some special environments such as humid environments and high temperature environments, this process also has certain applicability. In humid environments, adhesive materials with good waterproof performance should be selected and appropriate waterproof measures should be taken to ensure that the bonded area is not affected by moisture; in high temperature environments, the high temperature resistance of the adhesive material should be considered to avoid the decrease of bonding force due to high temperature.
[0023] (iii) Bonding of large building materials: With the development of building materials, large tiles and rock plates are increasingly widely used. This process can better meet the bonding needs of large building materials by optimizing the construction steps and tool usage. When bonding large materials, the angle and pressure scraping force of the trowel should be more accurately controlled to ensure uniform distribution of the adhesive material to withstand the weight of the large material.
[0024] The beneficial effects of the present application are: 1. Improved bonding efficiency and full paste rate: Compared with the current industry practice of using square serrated trowels to groove on both sides (building base and building material), the gap between the adhesive strips pulled by the triangular serrated trowel is narrower. In terms of groove volume, ifFigure 5 As shown in the figure, when the side length of the square tooth spatula is 12 mm, the groove volume is 144h (h is the height), while the groove volume of the triangular sawtooth spatula is 1.5h (h is the height). Figure 6 As shown in the figure, due to the narrow gap and less air in the groove, air exhaust efficiency is higher, allowing for quick paving and air exhaust, thereby improving pasting efficiency and achieving a 100% slurry fill rate. This increased slurry fill rate ensures full contact between the adhesive material and the base layer and building materials, greatly enhancing the bond and improving the firmness of the pasting.
[0025] 2. Reduced construction labor intensity: When using a triangular serrated trowel to draw grooves, the contact surface with the tile / rock plate is a continuous point, such as Figure 7 As shown. The square tooth knife and the tile / rock plate are in contact with the "surface" rather than the "point", as shown. Figure 8 This "point contact" method significantly reduces the resistance between the blade and the tile / rock slab. This reduced resistance makes scraping easier and more comfortable for the applicator, requiring less effort, thereby reducing labor intensity and improving overall efficiency.
[0026] 3. Meeting the requirements of thin pasting: The present invention combines the use of a triangular serrated trowel and a square-toothed trowel. By rationally matching the two trowels on the base layer and building materials, the bonding thickness can be accurately controlled to ensure that the construction process meets the requirements of thin pasting. When square-toothed trowels are used, the bonding thickness is too thick due to the larger tooth shape, and thin pasting cannot be achieved; and when triangular serrated trowels are used, the bonding thickness will be too thin, which is not conducive to the normal bonding effect of the bonding material. Through the optimized combination of the two trowels, a thin pasting effect with a bonding thickness of 5 to 8 mm is achieved, which not only ensures the bonding strength but also meets the construction requirements of thin pasting.

[0038] In order to make the objects, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.
[0039] Embodiment 1 The present embodiment provides a thin-pasting construction process, which comprises the following steps: (1) The triangular sawtooth-shaped trowel is used to press and scrape the cement-based adhesive on the building wall surface, the specification of the triangular sawtooth-shaped trowel is tooth height, tooth width 3 mm, and triangular side length 3.35 mm, and the cement-based adhesive is uniformly covered on the wall surface during pressing and scraping.
[0040] (2) Then the triangular sawtooth-shaped trowel is used again to supplement the cement-based adhesive, and the cement-based adhesive is pressed and scraped at an angle of 45° with the building wall surface, which is verified by practice and can ensure uniform distribution of the cement-based adhesive while controlling the thickness of the adhesive layer.
[0041] (3) At the same time, the square-tooth-shaped trowel is used to press and scrape the cement-based adhesive on the ceramic tile, the length of the square-tooth-shaped trowel is 12 mm, and the cement-based adhesive is also uniformly applied on the back surface of the ceramic tile.
[0042] (4) Then use the square toothed trowel to supplement the cement-based adhesive again, and press and scrape the cement-based adhesive at an angle of 45° with the tile.
[0043] (5) Finally, press and scrape the building wall and the pressed and scraped tile, and pay attention to the proper pressure during the pressing and scraping process, so that the cement-based adhesive can fully fill the gap between the base layer and the tile, and ensure firm adhesion. As shown in Figure 9 and Figure 10 , the thickness of the cement-based adhesive after adhesion is 5.25 mm, which meets the requirements of thin adhesion (5-8 mm).
[0044] Example 2 The thin adhesion construction process provided in this embodiment includes the following steps: (1) Use the triangular sawtooth trowel to press and scrape the cement-based adhesive on the building wall, and the operation requirements are the same as those in Example 1.
[0045] (2) Use the triangular sawtooth trowel to supplement the cement-based adhesive again, and press and scrape the cement-based adhesive at an angle of 60° with the building wall. The 60° angle has its unique advantages in construction, which can adjust the distribution and thickness of the adhesive layer to a certain extent.
[0046] (3) Use the square toothed trowel to press and scrape the cement-based adhesive on the tile.
[0047] (4) Use the square toothed trowel to supplement the cement-based adhesive again, and press and scrape the cement-based adhesive at an angle of 60° with the tile.
[0048] (5) Finally, press and scrape the building wall and the pressed and scraped tile, and pay attention to the proper pressure during the pressing and scraping process, so that the cement-based adhesive can fully fill the gap between the base layer and the tile, and ensure firm adhesion. As shown in Figure 9 and Figure 10 , the thickness of the cement-based adhesive after adhesion is 6.35 mm, which meets the requirements of thin adhesion (5-8 mm).
[0049] Example 3 The thin adhesion construction process provided in this embodiment includes the following steps: (1) Use the triangular sawtooth trowel to press and scrape the cement-based adhesive on the building floor. Since the construction environment of the floor is different from that of the wall, attention should be paid to the amount and uniformity of the cement-based adhesive during pressing and scraping, so as to ensure the flatness of the floor base layer.
[0050] (2) Use the triangular sawtooth trowel to press and scrape the cement-based adhesive at an angle of 45° with the building floor.
[0051] (3) Use the square-toothed trowel to press and scrape the cement-based adhesive on the rock plate. The weight and size of the rock plate are usually large, and the cement-based adhesive needs to be more evenly applied to ensure the stability of the bonding.
[0052] (4) Use the square-toothed trowel again to press and scrape the cement-based adhesive at an angle of 60° with the rock plate.
[0053] (5) Bond the pressed and scraped building floor and rock plate. Pay attention to the position and levelness of the rock plate to avoid tilting or unevenness. As shown in Figure 9 and Figure 10 , the thickness of the cement-based adhesive after bonding is 6.05mm, meeting the thin bonding requirement.
[0054] Example 4 The thin bonding construction process provided by the embodiment includes the following steps: (1) Use the triangular sawtooth trowel to press and scrape the cement-based adhesive on the building floor.
[0055] (2) Use the triangular sawtooth trowel again to press and scrape the cement-based adhesive at an angle of 60° with the building floor.
[0056] (3) Use the square-toothed trowel to press and scrape the cement-based adhesive on the rock plate.
[0057] (4) Use the square-toothed trowel again to press and scrape the cement-based adhesive at an angle of 45° with the rock plate.
[0058] (5) Bond the pressed and scraped building floor and rock plate. As shown in Figure 9 and Figure 10 , the thickness of the cement-based adhesive after bonding is 5.55mm, meeting the thickness requirement of thin bonding construction.
[0059] As can be seen from the above four examples, the thin bonding construction process of the present application can accurately control the bonding thickness by reasonably selecting the type of trowel and controlling the construction angle, achieve a thin bonding effect of 5-8mm, while ensuring the full bonding rate and bonding strength, improving the construction efficiency and reducing the labor intensity.
[0060] The above is merely a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
