Description

Technical Field

[0001] This invention relates to the field of building decoration technology, specifically to an adhesive interior wall brick structure and construction method. Background Technology

[0002] As people's requirements for building quality and standards increase, interior wall tiles that are easy to clean and maintain have been widely used in residential and public buildings.

[0003] Most existing interior wall tiles are laid on interior walls using cement-based adhesives. This method is time-consuming, material-intensive, labor-intensive, and costly. It also causes serious dust pollution during construction, makes cost control difficult, and makes it hard to guarantee the construction period. In addition, the bonding effect is limited by the quality of the cement and the curing conditions (it is not easy to work in low-temperature environments). As a result, there are many quality problems with the tiled walls after installation, with detachment being the most prominent. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an adhesive interior wall tile structure and construction method, which aims to solve the technical problems of easy detachment of ceramic interior wall tiles, high material cost and environmental unfriendliness caused by cement adhesive.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] Design an adhesive interior wall brick structure, including a facing brick layer and strip-shaped and / or block-shaped guide strips spaced apart on the base wall surface. The facing brick layer is fixed to the strip-shaped and / or block-shaped guide strips by corresponding structural adhesive blocks / points to form an air insulation cavity / layer between the facing brick layer and the base wall.

[0007] The strip-shaped guide bar is long or S-shaped.

[0008] The structural adhesive layer or structural adhesive bonding point is formed by neutral silicone structural adhesive.

[0009] The brick layer includes bricks and overlapping joints between them, and the overlapping joints are filled tightly with grout.

[0010] The sealant is a cement-based sealant or a reactive resin sealant.

[0011] The construction method for the adhesive-bonded interior wall tile structure includes pre-laying of wall tiles, base treatment, back treatment of wall tiles, and the following steps:

[0012] Setting of guide strips: First, moisten the base wall after the base treatment with water, and then use mortar with the same composition as the plaster layer of the base wall to make strips or / and blocks on the inner surface of the base wall to form the corresponding guide strips;

[0013] Wall tile installation: First, apply at least five structural adhesive lumps / points to the back of the tile, and at the same time apply at least two quick-curing adhesive lumps / bands to the back of the tile for temporary fixation during installation. Then, lay the tile on the corresponding guide strip from bottom to top along the wall. When laying, wait until the quick-curing adhesive reaches the bonding strength to prevent the tile from sagging before removing the external force fixing the tile.

[0014] Grouting: After 45-50 hours of application, use a scraper to fill the grout into the seams, making sure it is fully applied and tight. Then, use hemp fibers and a cloth to clean the surface.

[0015] In the step of setting the guide bars, the wall guide bars are set as vertical bars with a width of 75-85mm. The spacing of the guide bars is determined according to the distribution of the bonding points of each brick.

[0016] In the wall tile pasting step, pull-out tests of structural adhesive bonding guide strips and individual tiles are conducted on-site to obtain data on the amount of structural adhesive used on the tile at a single point / block, the thickness of the structural adhesive clump / point when the tile is bonded to the guide strip surface, and the bonding force of the structural adhesive clump / point. The amount of structural adhesive used on the tile at a single point / block is determined when the bonding strength of the structural adhesive clump / point is ≥0.6 MPa and the thickness of the clump / point is greater than the minimum bonding thickness of the structural adhesive clump / point.

[0017] The brick has a size of 300mm×600mm. Five structural adhesive blocks / points are arranged at its four corners and the center of the wall brick. The four corner blocks / points are arranged 45-55mm away from the edge of the wall brick. Fast-curing adhesive points / tapes are arranged 100mm on both sides of the structural adhesive block / point at the center.

[0018] The structural adhesive is a neutral silicone structural adhesive. The amount of adhesive used per brick / point, the coating thickness, and the bonding contact area are verified by using a vertical load-bearing capacity of more than 80 kg for a single 300mm×600mm brick.

[0019] Compared with the prior art, the main beneficial technical effects of the present invention are as follows:

[0020] 1. This construction method uses strip-shaped plaster layers (markers) instead of a complete plastering leveling layer as the bonding base for structural adhesive dots to adhere interior wall tiles. This reduces the area of ​​the plastering leveling layer, thereby reducing the use of materials such as cement and sand while still meeting the bonding strength requirements of the interior wall tiles, reducing dust and protecting the environment. In addition, the structural adhesive has stable performance and is less affected by the external temperature, solving the problem of difficult quality control in traditional wet construction methods during winter. Furthermore, it has strong resistance to thermal expansion and contraction after bonding, ensuring stable structural performance and preventing detachment. The bonding process of this invention is simple to operate and easy to control, which not only increases construction speed but also saves construction costs, improves bonding quality, and avoids the problem of interior wall tiles falling off.

[0021] 2. In the adhesive interior wall tile structure of this invention, the ceramic tiles do not directly contact the wall or reinforcing bars, thus forming an insulating air gap to achieve a heat preservation effect and save energy. Attached Figure Description

[0022] Figure 1 This is a schematic diagram of the adhesive interior wall brick structure of the present invention. In the diagram, 1 is the base wall, 2 is the strip reinforcement, and 3 is the facing brick layer.

[0023] Figure 2 This is a flowchart illustrating the construction process of the adhesive-bonded interior wall brick structure of the present invention. Detailed Implementation

[0024] The specific embodiments of the present invention will be described below with reference to the accompanying drawings and examples. However, the following examples are only used to illustrate the present invention in detail and do not limit the scope of the present invention in any way.

[0025] Unless otherwise specified, the instruments and equipment involved in the following embodiments are all conventional instruments and equipment; the raw materials involved are all commercially available conventional raw materials; and the construction methods involved are all conventional methods unless otherwise specified.

[0026] Example 1:

[0027] A type of adhesive-bonded interior wall tile structure, see Figure 1 It includes a brick layer 3 and strip-shaped guide bars 2 spaced apart on the surface of the base wall 1. The brick layer 3 is fixed to the strip-shaped guide bars by corresponding structural adhesive blocks / point bonding to form an air insulation layer between the brick layer 1 and the base wall 2.

[0028] For the construction method of the above-mentioned adhesive-bonded interior wall tile structure, please refer to [link / reference]. Figure 2 The main steps are as follows:

[0029] (I) Construction Preparation

[0030] 1. Before tiling, wall tiles should be unpacked and inspected. Select tiles that are consistent in size, flat and square in shape, without missing edges or corners, without cracks or peeling, and with uniform color according to design requirements. Any broken products, defective products, or products that affect the appearance should be rejected and strictly prohibited from use.

[0031] 2. When constructing brick walls with a height exceeding two meters, temporary scaffolding should be erected in advance. For ease of operation, the distance between the scaffolding and the wall edge should not exceed 400mm.

[0032] (II) Base treatment: Before the interior wall bricks are pasted, the masonry wall should be inspected. The surface of the base wall should be free of oil stains, release agents, dust and other contaminants. Ensure that the base wall is clean and tidy. The flatness and verticality deviation of the block base wall should not exceed the standard requirements. After all kinds of pipes, boxes and holes are treated, the masonry wall should be moistened with water in advance.

[0033] (III) Wall tile pre-layout: Before wall tiles are pasted, the wall tiles should be laid out using BIM layout technology according to the architectural drawings, the specifications and dimensions of the tiles, and the dimensions of the door and window openings.

[0034] The wall tile layout rules are as follows:

[0035] 1. Arrange the tiles from bottom to top. To make the wall tiles look nice and the construction convenient, and to prevent small tiles smaller than 50mm from appearing at the top, if the bottom is a whole tile and small tiles smaller than 50mm appear at the top, the tiles at the bottom and top should be adjusted evenly so that the top and bottom parts each have two large half tiles, and the middle part is all tiled with whole tiles.

[0036] 2. Door and window openings and external corners must be tiled with whole tiles. Cut tiles should be placed in the internal corners or the middle of the door and window openings. If the cut tile in the internal corners and the middle of the door and window openings is larger than 1 / 3 of the tile width, it can be pasted. If it is smaller than 1 / 3 of the tile width, two equal half tiles should be pasted.

[0037] 3. Ensure even distribution of brick joints. When encountering protruding pipes, supports, or other structures, use whole bricks to cut and fit them properly; do not use broken bricks as a makeshift solution.

[0038] Draw a detailed drawing and calculate the dimensions of the wall tiles to facilitate centralized processing of irregularly shaped interior wall tiles. On-site, using the 1-meter line as the control line, first mark several horizontal and vertical control lines according to the specific height of the wall. After marking the control lines, mark the wall tile dividing lines according to the layout detail drawing.

[0039] (iv) Marking: Before tiling, according to the architectural drawings and the specifications and dimensions of the facing bricks and the dimensions of the door and window openings, the wall bricks are laid out in advance using BIM technology. Based on the pre-arranged position of the wall bricks and the number of bonding points for each brick, the bonding position is determined. The position of the strip plastering base layer is determined by the bonding point position. According to the layout position of the strip plastering base layer in the BIM drawing, points are set in layers and mortar spots are made.

[0040] During on-site construction, the base wall is first moistened. Then, according to the layout of the strip plastering base layer in the BIM drawing, points are set in layers and mortar spots are made. When the mortar spots are about 70-80% dry, strip plastering base layers (referred to as "markers") are made using mortar with the same composition as the plaster layer. Figure 1 (As shown). The number of guide strips is determined based on the number of bonding points for each brick in the BIM drawing, and the width of the guide strips should preferably be 80mm.

[0041] (v) Dust removal on the back of wall tiles: When porcelain wall tiles leave the factory, there is usually dust or release agent on the back of the tiles. Such substances are one of the important factors that cause wall tiles to fall off. Therefore, before pasting, the dust on the back should be cleaned with a brush or rinsed with water and dried before pasting the wall tiles.

[0042] (vi) Marking the adhesive application area on the back of the brick: For commonly used 300mm×600mm interior wall tiles, apply structural adhesive in 5 places and marble adhesive in 2 places (for temporary fixation) evenly on the back of each wall tile. The structural adhesive is applied using the four corners and center method. The four corners are 50mm away from the edge of the wall tile, and the center point is the center of the wall tile. The marble adhesive is applied on both sides of the structural adhesive in the center, about 100mm away from the center of the structural adhesive. In order to more accurately locate the position of the structural adhesive during the wall tile construction process, use a red marking tool to mark the position of the structural adhesive before pasting.

[0043] (vii) Applying adhesive: After determining the application diameter and thickness (for commonly used 300mm×600mm interior wall tiles, the application diameter is 25mm and the thickness is 3mm), a hollow shim with the same dimensions as the bonding diameter and thickness is used to assist in the application process. To accurately control the amount of adhesive used, a graduated glue gun is used to calculate the amount of adhesive dispensed per millimeter of the glue gun. Then, the structural adhesive is applied to the marked area according to the actual amount of adhesive used. By controlling the application diameter, thickness, and amount of adhesive used, the extended bonding thickness meets the requirements (the extended bonding layer thickness should be 1.5-2mm) to achieve the purpose of controlling the bonding quality.

[0044] (viii) Tiling: In each section, the wall tiles are laid from bottom to top. The wall surface must be dry and clean when tiling, and a measuring tape should be placed at the bottom of the marked horizontal line.

[0045] Generally, the operation is carried out in groups of two. One person is responsible for applying the structural adhesive. After the adhesive is applied, it is handed to the other person. The second person holds the wall tiles with both hands and lays them from bottom to top on the pre-set shims, aligning the seams. It is important to lay the tiles according to the marked horizontal and vertical lines.

[0046] After laying one set, place the strips on the top edge and continue laying the second set. When pasting, hold the tamper in one hand and lean it against the pasted tile surface, and use the hammer in the other hand to tap the tamper all over (focus on tapping the bonding area firmly and flat).

[0047] When laying the tiles, wait until the marble adhesive reaches a certain strength before letting go; use the standard that the wall tiles do not sag. After the bottom two rows of tiles are pasted, start to stabilize the straightedge, use a spirit level to make the vertical joints vertical, and pull a horizontal line at the top to ensure that each tile is aligned and each layer is aligned.

[0048] After the wall tiles are laid, check whether the joint size is uniform and meets the requirements. If there are any crooked or uneven joints, straighten and fix them in sequence, first horizontally and then vertically, until they are straight.

[0049] (ix) Grouting: 48 hours after application, use a scraper to fill the grout into the seams, making sure it is full, firm and tight. Then wipe the surface clean with hemp fibers and a cloth.

[0050] Before grouting, the grout lines should be cleaned. You can use a damp, clean, soft-bristled brush to gently remove dust and other debris from the grout lines.

[0051] The grout should be stirred evenly and have a moderate viscosity to avoid dripping during the grouting process. Grouting should be done horizontally first and then vertically, and in a top-to-bottom order to avoid missing any areas. The grout can be wiped after it has hardened. When wiping the grout, be sure to smooth out any grout protruding from the brick joints.

[0052] (x) Inspection and Acceptance

[0053] 1. Visual inspection

[0054] 1) The type, specifications, pattern, color, and performance of wall tiles must comply with the design requirements and the relevant provisions of current national standards;

[0055] 2) Wall tiles must be laid firmly, without defects such as crookedness, missing edges, chipped corners, or cracks;

[0056] 3) The joints of the interior wall cladding tiles are tight, straight, and of uniform width. The tiles at the inside and outside corners are pressed in the correct direction, and the use of non-whole tiles is appropriate.

[0057] 4) The entire brickwork is cut and fitted together, with neat edges.

[0058] 2. Perform actual measurements and implement them according to the methods in Table 1.

[0059] Table 1. Allowable Deviations and Inspection Methods for Interior Wall Facing Tile Installation

[0060] .

[0061] (xi) Finished Product Protection

[0062] 1. Since the interior wall tile installation areas are mostly public areas with high personnel mobility during construction, in order to prevent damage caused by collisions with construction tools such as trolleys after the wall tiles are installed, structural adhesive can be used to fully adhere the wall surface below one meter (when applying the adhesive, a scraper can be used to spread and smooth the structural adhesive).

[0063] 2. Complete the installation of water, electricity, and equipment in advance to prevent damage to the facing bricks.

[0064] 3. Strictly prevent cement slurry, lime slurry, paint, pigments, varnishes and other liquids from contaminating the brick wall surface. At the same time, educate construction workers not to write or draw on the brick wall or to step on or touch it with their hands, so as not to contaminate the wall surface.

[0065] 4. After the structural adhesive is applied, it should be protected from impact and vibration.

[0066] Application examples:

[0067] Construction Section 5 of a shantytown renovation project in Zhengdong New District

[0068] The process was carried out according to the steps in Example 1; the actual area of ​​the interior wall tiles was 20,168 square meters.

[0069] Calculated according to the 2016 edition of the "Henan Province Housing Construction and Decoration Engineering Budget Quota":

[0070] Cost Comparison: Based on the actual site conditions, the use of structural adhesive dots to bond interior wall tiles instead of traditional adhesives during the interior wall tile installation process innovated the construction process, accelerated the construction speed, improved construction efficiency, saved construction costs, effectively controlled the problem of hollow and detached interior wall tiles, ensured the construction quality of interior wall tile installation, and successfully passed the project acceptance, demonstrating significant social and economic benefits.

[0071] Economic benefit analysis:

[0072] The area of ​​an 80mm wide strip for plastering the base layer is 8067.2㎡. Specifically, taking a 300mm×600mm interior wall tile as an example, within a 600mm range, there are three 80mm wide strips for plastering the base layer, corresponding to the five structural adhesive bonding points of the tile. 240mm / 600mm = 40%, and the plastering area is 40%. Compared to plastering the entire base wall, this saves 60% of the plastering area. The reduced plastering area also saves on labor costs.

[0073] (1) The actual area of ​​interior wall tiles was 20,168㎡, and the area of ​​strip plastering base layer was 8,067.2㎡, saving 12,100.8㎡ of plastering layer area. Among them, the material cost and labor cost were reduced compared with traditional construction:

[0074] Material cost: 6.75 yuan / ㎡ × 0.6 = 4.05 yuan / ㎡

[0075] Labor cost: 16 yuan / ㎡ - 10 yuan / ㎡ = 6 yuan / ㎡

[0076] Total: 12100.8㎡ × (4.05 + 6) yuan / ㎡ = 121613.04 yuan

[0077] (2) The actual area of ​​interior wall tiles was 20,168㎡. Compared with traditional cement mortar bonding, the structural adhesive used to bond interior wall tiles saved on material and labor costs respectively:

[0078] Material cost: 18.9 yuan / ㎡ - 8.8 yuan / ㎡ = 10.1 yuan / ㎡

[0079] Labor cost: 45 yuan / ㎡ - 40 yuan / ㎡ = 5 yuan / ㎡

[0080] Total: 20168㎡ × (10.1 + 5) yuan / ㎡ = 304536.80 yuan

[0081] (3) Total cost savings per square meter of interior wall tile construction area: 4.05 + 6 + 10.1 + 5 = 25.15 (yuan / ㎡)

[0082] (4) Total savings: 121,613.04 yuan + 304,536.80 yuan = 426,149.84 yuan

[0083] Social benefit analysis:

[0084] Green and environmentally friendly: Due to the severe situation of dust control and the growing awareness of green and environmental protection, the construction method in Example 1 was adopted, which reduced the use of materials such as sand, cement and water, and reduced the area of ​​the plaster layer by 12,100.8㎡, accounting for 60% of the total plaster area; thus achieving the goal of green construction.

[0085] High pass rate: By adopting the construction method in Example 1 and utilizing the excellent bonding properties of structural adhesive, the pass rate of interior wall tile installation is improved, reducing the amount of subsequent maintenance and saving maintenance costs.

[0086] The structural adhesive has relatively stable performance and is less affected by temperature, which solves the problem of difficulty in ensuring the quality of wet bonding during winter construction.

[0087] The present invention has been described in detail above with reference to the accompanying drawings and embodiments; however, those skilled in the art will understand that, without departing from the concept of the present invention, various specific parameters in the above embodiments can be changed, or relevant components, structures and materials can be equivalently substituted, thereby forming multiple specific embodiments, all of which are common variations of the present invention, and will not be described in detail here.
