Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a novel anti-air-drum construction method of a heat-insulating nanometer heat-insulating gel material used on a concrete surface. Background Art

[0002] Prior art (1): Manual slurry beating and hair removal. The main construction process is: base treatment → preparation of polymer cement mortar for standby use → slurry beating and hair removal → burr maintenance → preparation of insulation layer ash cake → insulation material on the wall → anti-cracking mortar (with embedded fiberglass mesh). The main operation method is: use a paddle made of folded wire mesh, then dip an appropriate amount of slurry on the back of the paddle, beat it hard and pull it quickly to form a rough bottom and sharp top thorn-like hair surface, so that the base treatment is uniform and firm, and then start maintenance on the second day after slurry beating. When the weather is dry, it is advisable to maintain it 5 hours after slurry beating. The maintenance period should be no less than 3 days. The maintenance effect should be such that it cannot be broken by hand. When the hand is pressed on the slurry, there is a burr feeling before the insulation material can be put on the wall.

[0003] However, the prior art has the following shortcomings: after beating and shaking off the hair, special personnel need to be arranged for regular maintenance, which will increase labor costs; at the same time, if individual parts are not properly maintained or too much water is sprayed during maintenance, it may lead to insufficient burr strength and cause burrs to fall off, eventually leading to hollowing in the later stage.

[0004] Existing technology 2: Applying interface agent on the base layer, that is, applying interface treatment agent on the aluminum form concrete base layer with a manual roller. After testing this construction technology at the construction site, it was found that the insulation layer is prone to large-area hollowing, and rectification will increase labor and material costs. Summary of the invention

[0005] In view of this, the present invention provides a novel heat-insulating nano-insulating gel material anti-air drum construction method used on the concrete surface, which reduces later repairs, improves project quality, reduces material consumption, reduces project costs, and speeds up construction progress.

[0024] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0025] The following is combined with Figure 1 The present invention is described in further detail.

[0026] The embodiment of the invention discloses a novel anti-cavitation construction method of a thermal insulation nanometer heat insulating gel material used on a concrete surface.

[0027] Reference Figure 1 A novel anti-air-drum construction method of a thermal insulation nano-insulation gel material used on a concrete surface includes the following construction steps:

[0028] S1: base 1 processing;

[0029] S2: spray two-component vitrified tile adhesive 2;

[0030] S3: making thermal insulation ribs on the wall to form thermal insulation layer 3;

[0031] S4: Insulation layer construction;

[0032] S5: Putty layer 5 is constructed and finishing layer 6 is made.

[0033] The use of spray-coated two-component vitrified tile adhesive 2 has a low hollowing rate and does not require special treatment, saving costs such as materials and labor, eliminating safety hazards caused by repairs, and speeding up construction progress.

[0034] Among them, in S1, the base layer 1 is processed as follows:

[0035] The on-site base treatment was not roughened or roughened. After the wall surface was rinsed clean with water, the two-component vitrified tile was sprayed.

[0036] In S2, the vitrified tile adhesive powder and the vitrified tile liquid are mixed evenly in a certain proportion, and the two-component vitrified tile adhesive 2 after fine screening is put into the spraying equipment for spraying.

[0037] The spraying equipment is an oil-free air compressor, which has a feeding pipe and a nozzle, and the two-component vitrified tile adhesive 2 is sprayed out through the feeding pipe and the nozzle.

[0038] Specifically, the spraying two-component vitrified tile adhesive 2 is intended to improve the bonding strength between adhesive materials and solve common problems such as hollowing and falling off. It is composed of vitrified tile adhesive powder and vitrified tile liquid material, which are mixed in a specific ratio before use. It has high strength and water resistance, deformation resistance, long-lasting anti-falling and impact resistance, and can effectively prevent hollowing.

[0039] In this embodiment, spraying is adopted on site for construction. The vitrified tile adhesive powder and the vitrified tile liquid are prepared in a ratio of 1:2.5 (by weight). After being fully stirred, they are allowed to stand for 3 minutes and then stirred again before use. The stirred adhesive should be used up within 2 hours.

[0040] Two-component vitrified tile adhesive 2 has the following advantages:

[0041] Strong bonding: can effectively bond to smooth, low-water-absorption base surfaces to prevent hollowing and falling off.

[0042] Weather resistance and durability: It has high water resistance, weather resistance and heat resistance, good durability, and is suitable for a variety of indoor and outdoor environments.

[0043] Anti-seepage and anti-cracking: It is compatible with cement mortar, has excellent anti-seepage properties, and can effectively resist the occurrence of cracks.

[0044] Green and environmentally friendly: non-toxic and harmless, in line with environmental protection requirements, safer to use.

[0045] Easy construction: no need to wait for drying, which simplifies the construction process and improves efficiency.

[0046] Among them, in S3, the insulation reinforcement is an important step in the construction of the exterior wall insulation project, which aims to ensure the thickness and flatness of the insulation layer 3 and improve the construction quality. The following are the specific steps and key points of the insulation reinforcement:

[0047] Preparation for rib punching: Clean and position, and lay out the lines before construction. Clean all construction surfaces, determine the thickness according to the requirements of the construction design, and use an infrared level to mark the horizontal and vertical standard lines.

[0048] Making rib strips: When making ribs, use the most convex point of the wall as the basis to make the finished surface of the Zhaopu rib.

[0049] Squaring the Yin and Yang corners: When squaring the Yin and Yang corners for plastering, you should first make a baseline at the Yin and Yang corners, use a square ruler to square the outer corner first, then pop out the plastering reference line at the wall corners and ceiling, and make plaster cakes and ribs on the upper and lower ends of the reference line.

[0050] Through this series of steps, the thermal insulation ribs can effectively ensure the construction quality and effect of the thermal insulation layer 3.

[0051] In S4, after the construction of the heat insulation layer is completed, the wall anti-cracking layer 4 is constructed. The anti-cracking layer 4 is applied with anti-cracking mortar.

[0052] The construction method of applying anti-cracking mortar mainly includes the following steps:

[0053] Preliminary preparation:

[0054] Material preparation: anti-cracking mortar, clean water, mixing tools, construction tools, etc.

[0055] Base layer 1 treatment: Ensure that base layer 1 is clean, flat, free of oil and dust, and repair cracks or holes.

[0056] Mixing anti-crack mortar:

[0057] Mix ingredients in proportion: Mix anti-cracking mortar powder and clean water in proportion.

[0058] Stir evenly: Use an electric stirrer to make sure there is no lumps or dry powder, and to form a uniform slurry.

[0059] Construction of anti-crack mortar:

[0060] Apply the base mortar: Apply evenly on the surface of the two-component vitrified tile adhesive 2, with a thickness of 1-2 mm.

[0061] Laying anti-cracking mesh: Before the base mortar dries, lay the anti-cracking mesh made of fiberglass mesh and compact it.

[0062] Apply surface mortar: Apply the second layer of mortar evenly on the anti-cracking net with a thickness of 2-3 mm.

[0063] Maintenance and anti-cracking mortar:

[0064] Moisturizing maintenance: Cover the mortar surface to keep it moist and prevent it from drying out too quickly.

[0065] Prevent vibration: Avoid vibration or impact on the construction site.

[0066] The thermal insulation layer is thermal insulation nano gel, which is applied by coating. Thermal insulation nano gel has excellent thermal insulation effect, and its advantages are as follows

[0067] Superior thermal insulation performance: Nano aerogel thermal insulation material has nanopore super thermal insulation performance. Its total thermal conductivity of powder and block are extremely low at room temperature and pressure. It is one of the materials with the lowest thermal conductivity in the field of high-temperature thermal insulation in the world.

[0068] Unique flame resistance: This gel material is able to maintain its insulating properties at high temperatures, significantly outperforming other lightweight insulation materials.

[0069] Environmentally friendly and non-toxic: The product is made of environmentally friendly materials, is non-toxic and harmless, meets national environmental protection standards, and is harmless to the human body.

[0070] Easy construction: The thermal insulation nano-insulation gel is easy to construct and does not require special tools. It can be applied directly, saving labor time and costs.

[0071] In S5, the putty layer 5 is constructed and the finishing layer 6 is made, and the finishing layer 6 is latex paint.

[0072] The hollowing problem that is easy to occur after the thermal insulation material is applied to the exterior wall is relatively common, and there is no more economical and practical solution. After testing various base layer 1 treatment methods on the construction site, it was found that after the vitrified tile back glue spray treatment, the base layer 1 is rougher and has higher strength. After the thermal insulation gel is applied, no hollowing problem is found.

[0073] Preparation and application of vitrified tile adhesive. Mix the vitrified tile adhesive powder and vitrified tile liquid in a certain proportion, sieve through a drain basin, and put the two-component vitrified tile adhesive 2 into the air compressor tank. Use an oil-free air compressor to evenly spray the two-component vitrified tile adhesive 2 on the base layer 1.

[0074] After the strength of the vitrified tile backing glue reaches the standard requirements, thermal insulation ribs can be made on the wall. After the strength of the ribs reaches the standard requirements, the new thermal insulation nano-insulation gel can be constructed on the wall.

[0075] The present invention eliminates the process of spraying water for each layer, and uses a device that can improve efficiency to replace manual slurry beating and hair removal, which not only solves the burr quality problem, but also speeds up the construction progress and saves material and labor costs.

[0076] The invention has good application effect and broad prospects. Compared with the prior art, the invention has less comprehensive material loss, lower labor cost, lower hollowing rate and higher construction efficiency; it also reduces later repairs, improves project quality, reduces material consumption, reduces project costs and speeds up construction progress.

[0077] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core ideas. The above are only preferred implementation methods of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can also make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the protection scope of the present invention.
