Description

Technical Field

[0001] The present invention relates to the technical field of floor construction, and more specifically, to a wear-resistant composite floor construction method. Background Art

[0002] With the rapid development of modern industrial and commercial buildings, the performance requirements of flooring, as an important part of the interior ground of buildings, are becoming increasingly stringent, especially in environments with high traffic, heavy loads and frequent friction. The wear resistance, durability and maintenance cost of the flooring have become the focus of common concern for designers, constructors and users.

[0003] Traditional floor materials, such as ordinary cement floors and terrazzo floors, although they meet basic usage requirements to a certain extent, often show obvious performance deficiencies when facing complex working conditions such as high-intensity wear, chemical corrosion, and long-term heavy loads. For example, they are easy to wear, crack, and dust, which seriously affect the service life and aesthetics of the floor. Although some existing floor construction methods can solve this problem, in actual applications, the overall strength and durability of the floor after construction are still unsatisfactory. Some floors still have a large number of bubbles and voids after construction, which greatly affects the density and crack resistance of the floor. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wear-resistant composite floor construction method.

[0005] To achieve the above purpose, the present invention provides the following technical solution: a wear-resistant composite floor construction method, the construction method steps are as follows: Step 1: Base layer pretreatment; Step 2: Interface agent treatment; Step 3: Layered pouring and vibration; Step 4: Spreading and curing of wear-resistant materials; Step 5: Maintenance and treatment; Step 6: Quality inspection; Step 7: Cutting and caulking expansion joints.

[0006] As a further improvement of the technical solution of the present invention, the specific operation steps of the base pretreatment in step 1 are as follows: S101. Use an electric grinder or a manual grinder to fully grind the base layer to remove the slurry, oil stains, loose particles and impurities on the surface of the base layer until the solid concrete layer is exposed, and ensure that the surface of the concrete layer is flat; S102. Use a vacuum cleaner or broom to clean the dust and impurities generated by grinding; S103, washing the cleaned concrete surface; S104. After washing, cover the concrete surface with a dustproof cloth, and then ventilate and let stand for 12-24 hours until the concrete surface is dry; S105. Remove the dustproof cloth and proceed to the next step of construction.

[0007] As a further improvement of the technical solution of the present invention, the construction steps of the interface agent treatment in step 2 are specifically as follows: S201. Check the humidity of the construction environment. When the humidity of the construction environment is less than 70%, keep the room ventilated. S202, use roller brushing or mechanical brushing to evenly apply the interface agent on the surface of the concrete layer; S203. Control the coating thickness to be no less than 3 mm as required, so that the interface agent can fully penetrate the concrete surface to form a strong bonding layer; S204. After painting, dry naturally for 12-24 hours under ventilation conditions, and add dust-proof nets at the air inlet and outlet; S205. During the drying process, check the drying state of the interface agent every 3 hours to observe whether there is any abnormal phenomenon such as poor drying or incomplete curing.

[0008] 4. The wear-resistant composite floor construction method according to claim 1 is characterized in that the construction steps of layered pouring and vibrating in step 3 are as follows: S301, selecting concrete with a strength not less than C25, and then preparing conventionally added admixtures such as anti-cracking agent, water reducing agent, and early strength agent, and mixing and stirring them according to conventional mixing ratios to form a concrete agitator; S302, according to the thickness of the floor to be constructed, first lay and pour a layer of concrete mixture, and then vibrate it with an insert or flat vibrator to remove bubbles and cavities inside the concrete mixture, and control the thickness of the concrete mixture to be not less than 1 cm; S303, after standing for 30-60 minutes, continue the above steps to lay another layer of concrete mixture and maintain the same operation, then after standing for another 30-60 minutes, lay another layer of concrete mixture and maintain the same operation; S304. Use a scraper to smooth the surface of the top layer of concrete mixture.

[0009] As a further improvement of the technical solution of the present invention, the construction steps of spreading and curing the wear-resistant material in step 4 are specifically as follows: S401, when the uppermost layer of concrete mixture has initial setting strength, evenly spray or brush a curing agent on the upper surface of the uppermost layer of concrete mixture, and then spread a wear-resistant material; S402. Spread the wear-resistant material twice, and keep the amount spread evenly on the surface of the concrete mixture each time; S403. After spreading, use a trowel to perform multiple grinding and grouting to fully combine the wear-resistant material with the concrete mix; S404. The speed of the trowel is kept slow in the initial troweling stage, and is gradually increased in the finishing stage as the concrete mixture gradually solidifies.

[0010] As a further improvement of the technical solution of the present invention, the construction steps of the curing treatment in step 5 are specifically as follows: S501. After the above steps are completed, the constructed floor is maintained for 7 days; S502.

Spray the wet cloth covering the floor surface again every other day.

[0011] As a further improvement of the technical solution of the present invention, the quality inspection in step six includes on-site inspection and acceptance. The on-site inspection is used to inspect the flatness, hardness, and wear resistance of the floor using inspection equipment during the construction process. After the inspection is completed, the inspection results are recorded for quality assessment. During acceptance, the acceptance standards formulated before construction are compared, including the appearance quality, dimensional deviation, and strength of the floor, to ensure that they meet the acceptance standards.

[0012] As a further improvement of the technical solution of the present invention, the construction steps of the expansion joint cutting and caulking treatment in step seven are specifically as follows: S701, after the above steps are completed, wait for 3 days and start cutting the expansion joint; S702, marking the position where cutting is required; S703, using a cutting machine to perform a cutting operation on the position of the line mark to form an expansion joint; S704, after the cutting is completed, the dust and impurities generated during the cutting process are cleaned; S705, rinse the upper surface of the floor, and after rinsing, let it stand and dry; S706, after drying, use a caulking material to caulk the expansion joint; S707. After the caulking is completed, wait for the caulking material to completely dry and solidify and check the sealing of the expansion joint.

[0013] Beneficial effects of the present invention: The present invention detects the humidity of the construction environment before applying the interface agent, as well as controls the thickness and checks the drying state during the application process, thereby ensuring that the interface agent can fully penetrate the concrete surface to form a strong bonding layer, thereby improving the overall strength and durability of the floor, and reducing quality problems caused by improper interface agent treatment; adopts a layered pouring and vibrating method, and through multiple laying and vibrating of the concrete mixture, ensures that the thickness of the floor is uniform, internal bubbles and voids are effectively eliminated, improves the density and crack resistance of the floor, and reduces quality problems caused by internal defects of the concrete; and sprays a curing agent and spreads a wear-resistant material when the concrete mixture is initially set, and fully combines the wear-resistant material with the concrete mixture through multiple grinding and grouting, thereby improving the wear resistance and hardness of the floor.

[0024] In summary, the present invention designs a wear-resistant composite floor construction method. During construction, first, use an electric grinder or a manual grinding tool to fully grind the base layer to remove the floating slurry, oil stains, loose particles and impurities on the surface of the base layer until a solid concrete layer is exposed, and ensure that the surface of the concrete layer is flat. Use a vacuum cleaner or a broom to clean the dust and impurities generated by grinding, rinse the cleaned concrete surface, cover the concrete surface with a layer of dustproof cloth, and then ventilate and stand for 12-24 hours until the concrete surface is dry, remove the dustproof cloth, and proceed to the next step of construction; Secondly, check the humidity of the construction environment. When the humidity of the construction environment is less than 70%, keep the environment ventilated and use a roller or mechanical brush to evenly apply the interface agent to the surface of the concrete layer. The thickness of the application should be controlled to be no less than 3mm as needed, so that the interface agent can fully penetrate the surface of the concrete and form a strong bonding layer. After the application is completed, dry it naturally under ventilation for 12-24 hours, and add dustproof nets at the air inlet and outlet. During the drying process, check the drying state of the interface agent every 3 hours to observe whether there is any abnormal phenomenon of poor drying or incomplete curing. Then, select concrete with a strength not less than C25, and then prepare conventional anti-cracking agent, water reducing agent, early strength agent and other admixtures, mix and stir according to the conventional mixing ratio to form a concrete mixture, and according to the thickness of the floor to be constructed, first lay and pour a layer of concrete mixture, and then use an inserted or flat vibrator to vibrate to remove bubbles and voids inside the concrete mixture, and control the thickness of the concrete mixture to be not less than 1cm, after standing for 30-60 minutes, continue the above steps to lay another layer of concrete mixture and keep the same operation, and then after standing for another 30-60 minutes, lay another layer of concrete mixture and keep the same operation, and use a scraper to scrape the surface of the top layer of concrete mixture; Further, when the uppermost layer of concrete mixture has initial setting strength, the curing agent is evenly sprayed or brushed on the upper surface of the uppermost layer of concrete mixture, and then the wear-resistant material is spread. The wear-resistant material is spread twice, and the amount of each spread is kept uniform on the surface of the concrete mixture. After the spreading is completed, a trowel is used to perform multiple grinding and grouting to fully combine the wear-resistant material with the concrete mixture, wherein the speed of the trowel is kept slow in the initial troweling stage, and the speed of the trowel is gradually increased as the concrete mixture gradually solidifies in the finishing stage; Then, after the above operations are completed, the constructed floor is maintained for 7 days. During the maintenance period, the floor is covered with a wet cloth, which is close to the floor surface and completely covered. The wet cloth covering the floor surface is sprayed and wetted again every other day. Then, use testing equipment to conduct on-site testing of the flatness, hardness, and wear resistance of the floor. After the test is completed, record the test results for quality assessment. During acceptance, compare the acceptance standards formulated before construction, including the appearance quality, dimensional deviation, and strength of the floor, to ensure that it meets the acceptance standards; Finally, after the above operations are completed, wait for 3 days and start cutting the expansion joints. Mark the positions where cutting is required, and use a cutting machine to cut the marked positions to form expansion joints. After cutting, clean the dust and impurities generated during the cutting process, rinse the upper surface of the floor, and after rinsing, let it stand to dry. After drying, use caulking material to caulk the expansion joints. After caulking, wait for the caulking material to completely dry and solidify and check the sealing of the expansion joints.
