Description

Method for carrying out floor board of structure and floor board of structure carried out by its method}

The present invention relates to a construction method of building floors and walls, and in particular, while reducing labor and construction costs, and not vulnerable to moisture and fire, and excellent durability and wear resistance, the construction method and method of construction of the finishing material of the building does not require continuous maintenance It is about the finish of the building constructed by.

The floor surface (including the interior and exterior of the building and the evacuation stairs), which is always in contact with the human body, should have excellent performance such as texture, touch, and warmth, and be always comfortable. In addition, there should be no rebound and vibration. Therefore, the surface of the floor can be applied to mortar on concrete slabs, artificial grind finishes, marble, granite, tile, etc., or floor tiles, commonly referred to as flooring, or vinyl tiles, rubber tiles, cork tiles, etc. It is constructed by using a sheet-shaped synthetic resin product.

Among them, the artificial stone finish finishing method provides many advantages over other building floor finishing methods in terms of various technical aspects such as durability, non-combustibility, field applicability, workability, economical efficiency, and maintainability. It has been used as a process.

As a conventional construction finishing method using cement material, the artificial artificial stone finishing method, which has been used for a long time in the construction site, is a cement mortar mixed with a mixture of back cement and colored natural stones of 5-10 mm size to realize exterior. After manufacturing and coating, the surface is polished to a thickness of 3 ~ 5mm using a mill grinder to provide a beautiful bottom surface.

However, such artificial artificial stone finishing method causes the problem of wastewater mixed with harmful substances including stone powder by using a large amount of water (water) in the surface polishing process, and its use is currently strictly controlled. It is true. Under the current Water Quality Preservation Act, the enforcement of the on-site sewage method requires compliance with administrative procedures for reporting on wastewater generation, proper treatment facilities, management and implementation.

Moreover, this method also relies on manpower entirely for construction methods, which raises the cost of construction work due to higher labor costs, which has recently given way to cheaper resin finishes.

Resin finishes are not only vulnerable to moisture by the resin adhesive construction, but also require continuous maintenance, inferior in durability and abrasion resistance compared to the artificial artificial stone finishing method, and are vulnerable to fire.

Therefore, the development of alternative finishing methods that can be applied to multi-use facilities used by many unspecified people such as schools, public facilities, and neighborhood living facilities is one of the most urgent and urgent challenges for professionals in architecture design and construction. It is situated as one. Nevertheless, no clear solution has been proposed.

Meanwhile, the building law and the statutory provisions for evacuation stairs require that non-combustible finishing materials be used for evacuation stairs, but some of them are expensive due to the high cost of using non-combustible materials such as stone or ready-made terrazzo plates. Although it is illegal in the field, non-combustible materials are used in practice. Thus, it is true that such practices also must be regulated or appropriate action taken.

As a result, as described above, the development of a legal and economical non-abrasive finishing method that can be applied to the floor or evacuation stairs, according to the exit of the artificial stone finishing method, remains another challenge in construction technology.

The present inventors have developed a finishing method having economic feasibility on the background of such a realistic problem, and look at the elements for review of the technical approach of the present invention.

1. Review of available materials to meet nonflammability

In order to meet the non-combustible finish, it is necessary to use non-combustible materials as construction materials. When classifying the target materials into large categories, stone, cement (lime), ferrous metals, ceramic materials, special materials such as carbon materials, etc. This can be a target. However, as a result of a comprehensive review on economic feasibility, field workability, and supply and demand, the method using cement materials was set as the first priority R & D goal. If the objective is not achieved, the research and development of secondary materials is conducted. Promoted.

2. Review of cement material

Most of modern buildings are made of cement structures, and a separate finishing material is installed on it. The main point of attention here is, "Why should I install a separate finishing material on a concrete or cement mortar base?" It is called.

In other words, if it is possible to find the technical or functional reason for not using the ground surface itself of cement mortar as the finishing surface and the method to solve the problem, use the cement mortar construction itself for finishing. It would be possible to omit the construction of additional finishing materials.

This can be expected to reduce the cost of construction and the reduction of air, so first of all examined the reasons why the ground cement mortar plaster itself can not be used as a finishing, in a variety of aspects, and the results are summarized as follows.

First, cement mortar plastering surface has poor aesthetic appearance, and there is no variety of choices for exterior effect. It can be seen that this is due to the cement and aggregate materials used, and the paradoxical interpretation that it can be solved by using or supplementing cement, aggregate, and other materials which can have a variety of appearance and variety.

Even though a very simple solution would be possible, the development of the present invention has been made in light of the fact that the cement mortar plastering has been a cause for neglecting the research of the technician's conception of finishing ground.

Second, when cement mortar is applied to the bottom surface, cement paste film is formed on the surface by bleeding and boiling, which not only limits the external effect but also causes dust generation due to wear. It is the fact that the construction of the finishing materials. This phenomenon increases as the ratio (W / C) of the water to the soil or powder component and cement contained in the aggregate is high.

Therefore, it is possible to solve the problem by removing soil powder or powder component in the aggregate used at the source, restraining the surface film formation as much as possible by lowering the W / C ratio, and removing the unavoidable film. A study was conducted on the production and supply facilities of aggregates, on-site workability improvement of cement plaster mortar, and on the removal of film and tools.

Third, the surface of the cement mortar finish according to the 1: 3 compounding ratio (standard construction standard specification) currently used is insufficient in compressive strength and abrasion resistance for use as an exposure finish, and the cement mortar finish surface is exposed to moisture and air. In case of prolonged exposure, weathering occurs and adhesion is weakened. If there is a passage on it, it is easily worn and dust is generated.

The technical approach to solve this problem is that the compressive strength of cement mortar can be increased by increasing the amount of cement input, so that the mixing ratio can be adjusted by submixing (to date, the mixing ratio of cement for mortar for flooring should be 1: 3). Many materials and methods have already been developed for the surface hardening treatment method to prevent technicians from getting out of the textbook way of thinking, to prevent surface weathering, to enhance adhesion and to increase wear resistance. Only separate studies, surveys and supplementary tests will be necessary.

The present inventors in view of the above matters and solve the disadvantages and problems of the existing artificial stone grind finish method, while reducing labor costs and construction costs, not vulnerable to moisture and fire, its durability and wear resistance is excellent and continuous maintenance It has led to the development of methods for the construction of finishing materials that are not necessary and the finishing materials for the buildings constructed by the methods.

The present invention is to provide a building finishing material having both workability and economy and its construction method is its main object.

Another object of the present invention is to provide a building finishing material exhibiting a variety of high value-added natural stone texture constructed by the method of building the finishing material of the building.

The present invention for achieving the above object, the step of constructing a concrete floor structure; Constructing an undercoat plastering layer on an upper surface of the concrete floor structure; Using a colored artificial aggregate, cement and water mixed cement mortar, and constructing a finish finishing layer on the upper surface of the base coating layer; After the surface hardening of the finish finishing layer, after the step of removing the cement paste film formed on the surface, and further comprising the step of constructing a surface strengthening treatment layer on the surface of the finish finishing layer.

Hereinafter, preferred embodiments of the present invention will be described in detail.

As shown in Figure 1, the construction method of the finishing material of the building according to the present invention, the step of constructing the concrete floor structure 10 largely, the ground foundation plastering layer 20 on the upper surface of the concrete floor structure 10 And, using the cement mortar mixed and mixed colored artificial aggregate, cement and water, constructing the finishing finish plastering layer 30 on the top surface of the ground foundation plastering layer 20, and the finish finishing plastering layer (30) Comprising the surface strengthening layer 40 to protect the surface of the finish finishing layer 30 on the surface of the construction is made.

Concrete floor structure 10 refers to the foundation ground for laying a floor. The ground weave plastering layer 20 is constructed on the upper surface of the concrete floor structure 10 using ordinary cement mortar. At this time, in order to strengthen the adhesion with the finish finishing layer 30 to be described later, it is advantageous that the top surface of the base coating layer 20 to finish the rough surface such as furrow pattern. Depending on the design, non-slips or joints can be installed, preferably with a thickness of at least 20 mm.

The finish finishing layer 30 is a core configuration of the present invention corresponding to the conventional artificial stone grinding method. The thickness of the finish finishing layer 30 is set to 10mm to be installed in accordance with the height of the non-slip and joint strip of the ground foundation plastering layer 20.

At this time, the cement mortar, which is a material for constructing the finishing finishing layer 30, is a step of improving and mixing the selected colored artificial aggregate to a predetermined weight ratio, and mixing and stirring the cement by mixing the colored colored artificial aggregate. And water is added to the mixture of the colored artificial aggregate and cement, and then agitated as a whole.

Colored artificial aggregate, which is used to give a variety of colors and textures to the overall finishing materials for construction, can be used that has been processed by crasing colored rocks or by impregnating silica sand with pigments. You can freely adjust the particle size.

However, in order to minimize the cause of dust generation by removing the cement paste film which may be inevitably formed on the surface after construction, the colored artificial aggregate preferably has a particle size of at least 0.3 mm from which fine powder is removed. In addition, the color and specification of the aggregate, the mixing ratio is adjusted according to the site will be able to implement a variety of exterior effects.

As the cement mixed into the colored artificial aggregate, white cement and pigment may be used in addition to the gray cement used in general cement mortar. Pigments may or may not be selected depending on the choice of finish color, and may be saturated by adjusting the water dilution ratio.

The use of colored artificial aggregate in cement seems to raise the material cost slightly compared to general cement mortar. However, considering the price of cement and aggregates is a low-cost material with a small proportion of the total construction cost, this has an effect on economic value. Does not have

On the other hand, the selected colored artificial aggregate and cement mixing ratio is 1: 1 to 1.25: 1 is mixed. In the case of the existing cement mortar for cement, the cement mixing ratio of aggregate is 3: 1, but when it is used for exposure finishing, there is a problem in durability and abrasion resistance. As a result of the test analysis for durability, wear resistance, workability and exterior properties, it was confirmed that 1: 1 to 1.25: 1 is an optimal blending ratio.

According to the test results, as cement input is increased, durability, wear resistance and workability increase, but there is no further improvement in durability and abrasion resistance in sub-mixtures of 1: 1 or higher, while the cement paste coating layer on the surface becomes thick and workability and exterior property deterioration appear.

After the colored artificial aggregate and cement are mixed, water is added and mixed again. The ratio of water to cement (W / C) is applied in the range of about 40%, more preferably in the range of 37% to 43%. As the W / C ratio increases, the workability increases instead of the workability, and as a result of testing as a blending ratio between 30% and 50% to find the optimum blending ratio, there is no workability under 37% and surface bubbles above 43%. The occurrence of phenomenon and the appearance deterioration were observed, and it was confirmed that the optimum ratio was ± 40%.

However, the above W / C ratio is the ratio when no admixture such as water-sensitizer is used, and the use of admixture may significantly lower the W / C ratio, but it depends on the type of admixture and the manufacturer. The test mixture should be adjusted according to the manufacturer's specifications.

When the cement mortar is formed by mixing colored artificial aggregate, cement, and water and using the same, the finishing finishing layer 30 as shown in FIG. 2 or 3 may be formed on the surface thereof.

This film (cement paste film) is a phenomenon caused by the surplus of moisture in the cement mortar. Thus, when the cement mortar is beamed, the amount of water to cement (W / C) is lowered to a minimum, and the beam is sufficiently filled and the plaster pressure is increased. The formation thickness of the film can be minimized.

Therefore, after the finish finishing layer 30 is formed using cement mortar, finishing the surface of the finishing layer finishing layer 30, and additionally undergoing a step of removing the cement paste film formed on the surface after surface curing. do.

In the finishing of the surface of the finish finishing layer 30, either a sponge type plaster finishing method for surface water suction or a surface water vacuum suction finishing operation method using an air compressor is applied. The surface water is recycled to the cement mortar water. Therefore, it is possible to prevent environmental pollution due to the wastewater as in the prior art.

If the cement paste film is formed despite the step of finishing the surface of the finish finishing layer 30, the surface is hardened appropriately, and then cement formed on the surface using a surface treatment sanding tool such as a grinder. This is done by removing the paste coating.

After the cement mortar is made using the above materials and the finishing finishing layer 30 is formed through this, the finishing surface of the granite pattern as shown in FIG. 2 or the terrazzo tile illustrated in FIG. 3 appears. For the purpose of enhancing the durability and wear resistance of the cotton and preventing dust generation, a surface hardened layer 40 is additionally constructed.

At this time, the surface reinforcing material used in the surface reinforcing treatment layer 40 is a liquid incombustible transparent material that does not affect the appearance and non-combustibility, and is applied by at least two times with a brush or a roller and dried.

The surface hardening treatment layer 40 penetrates from the upper layer portion of the finishing finishing layer 30 to a lower predetermined depth to be integrated with the finishing finishing layer 30, and micropores of the finishing finishing layer 30 It is constructed to keep high density. This provides the effect of doubling the impact strength of the concrete.

In the case of building finishing materials in this way, a separate finishing material construction process can be omitted and there is no waste water generated during construction. In addition, the construction cost is significantly reduced compared to the factory terrazzo tile finish, which is used as a substitute for the existing artificial stone grind finish method, and because it is a non-flammable finish, it can be used without limitation for the finishing of evacuation stairs.

Looking at the summary of the improved effects obtained by applying the method of the present invention by item.

(1) Economics: Labor cost is reduced because there is no mill grinding process, and waste water treatment costs are not incurred. Only half of the construction cost of the artificial stone drainage or terrazzo tile finishing costs can be greatly reduced.

(2) Durability: The ground foundation plastering layer 20 secures the durability of the ground plastering by using cement mortar with the same ratio of 1: 3 as the standard standard for construction work like general cement mortar plastering that is used for existing floor plastering. In addition, the finish finishing layer 30 has a higher mortality than the general cement mortar finishing process by the mortar construction of the compounding ratio similar to the on-site artificial stone finish finishing method, the test result is equivalent to or more than the on-site artificial stone grinding finish method. .

(3) Abrasion resistance: In order to improve wear resistance, liquid surface reinforcement penetrating construction method was adopted. After surface reinforcement treatment, the compressive strength is over 600KG / CM ² , which is used as floor finishing in parking lots and factories that require high-grade wear resistance. It has a performance equal to or higher than the compressive strength of the hardner finish.

By using the aggregate which has removed soil powder and fine powder in advance, and removing the cement paste film on the surface, the surface reinforcement treatment process is carried out, and thus the effect of preventing dust is enhanced than other surface reinforcement methods. As a result of the verification test on the wear resistance, it was confirmed that it is equal to or more than the existing factory terrazzo tile finish.

(4) Non-combustible: All materials used are non-combustible materials and finish standards meet the requirements of the law.

(5) Exterior and Diversity: The artificial appearance of the granite finish is maintained by maintaining the exterior of the color aggregate used, and the exterior effect can be freely adjusted by adjusting the mixing ratio of pigment and color aggregate. It is more versatile and elegantly exterior than the water finish.

(6) Universality of construction technology: It can be easily installed by general plasterer without requiring special construction technology and skillful function, and the labor force by machine tool is reflected as much as possible to reduce labor cost and quality control.

(7) Universality of supply and demand: All materials used can be easily supplied.

(8) On-site feasibility of construction and rehabilitation period: Like general cement mortar plastering, traffic control is required only at the time of operation. No special measures are required for rehabilitation and the next day's transportation is possible.

(9) Conservativeness: In reality, the damage of the finished part is inevitable in the construction site, and it should be possible to repair it. This method is easy to repair the damaged part.

(10) Maintainability: There are no special precautions for maintenance during use, and it can be used for the facilities that are used in common by unspecified people such as schools, public facilities and neighborhood living facilities.

In the above-described embodiment, the surface of the finish finishing layer 30 is smoothed, but the degree of unevenness of the surface can be selected by adjusting the size of the aggregate to be used where a slip prevention or the like is required. In this case, the surface hardened layer 40 will also be absorbed by the coating along the uneven surface.

As described above, according to the present invention, a method of constructing a finishing material of a building which is not vulnerable to moisture and fire while reducing labor and construction costs, and excellent in durability and abrasion resistance and does not require continuous maintenance, and the building constructed by the method Finishes are provided. The scope of the present invention is not limited to the floor and the wall of the indoor, and of course, it can be widely used in the outdoors such as the floor of the parking lot.
