How to replace the piping pipe on the ondol floor using the cutting method {HOW TO REPLACE ONDOL FLOOR PIPING USING CUTTING METHOD}

The present invention relates to a method for replacing pipe pipes on an ondol floor using a cutting method, and more particularly, to a method for replacing pipe pipes on an ondol floor using a cutting method that is excellent in construction and can increase heating efficiency.

In general, domestic residential buildings adopt a floor heating method regardless of the type of housing, such as apartments, detached houses, and multi-family houses. Such floor heating is generally referred to as'ondol', and the floor surface of a residential area is heated to It is a method of heating the interior of the room.

In the floor heating structure according to the prior art, a floor slab of a building is formed, and lightweight foam concrete is poured on the top of the floor slab.

In addition, in the conventional floor heating structure, the pipe pipes are arranged after the lightweight foamed concrete is hardened, and a mortar or the like is plastered on the top of the lightweight foamed concrete in which the pipes are arranged. At this time, the lightweight foamed concrete is naturally horizontally adjusted during the pouring process due to its high fluidity, and the piping pipe positioned above it is also installed horizontally. In this way, after the construction of the ondol floor piping, if an abnormality occurs during use or the piped pipe becomes obsolete after a long period of time, it must be replaced with a new ondol pipe.

Therefore, looking at the existing ondol pipe replacement method, first, break the entire existing floor mortar layer on which the existing pipe with abnormality is installed, remove all the existing pipe and the existing floor mortar layer, and then arrange the new ondol pipes at appropriate intervals. A plastering mortar layer is formed on the wall and replaced with a new ondol pipe, or secondly, a new finishing mortar layer is formed by placing an ondol pipe on the top of the existing floor mortar layer while leaving the existing floor mortar layer with the old ondol pipe installed inside. However, in the former case, due to the nature of the plaster mortar layer, the surface is very strong, so it was very difficult and cumbersome to break it up and remove it, as well as safety such as cracks in the building due to the impact at this time. There was a problem, and it caused severe noise and dust, and because a large amount of building waste was discharged and had to be removed, it took a lot of time and cost to replace the ondol pipe, and a large amount of building waste caused environmental pollution. There were many problems such as becoming.

And in the latter case, there is no hassle of breaking the plastering mortar layer and then removing all of it, but this is a relationship that forms a finished mortar layer in which new ondol pipes are arranged on the top of the existing plastering mortar layer with old ondol pipes installed. As the thickness of the building is considerably thicker and the weight is so much, an unreasonable load is applied to the building itself, which greatly affects the life of the building, which inevitably leads to the risk of a safety accident, and the building's ceiling is lowered after piping to use the building. There was discomfort.

Throughout the present specification, when a part "includes" a certain component, it means that other components may be further included rather than excluding other components unless otherwise stated.

Here, FIG. 1 is a flow chart of a method for replacing a pipe pipe on an ondol floor using a cutting method according to an embodiment of the present invention, and FIGS. 2A to 2F are processes in a method for replacing a pipe pipe on an ondol floor using a cutting method according to an embodiment of the present invention. It is a flow chart, and FIG. 3 is a flow chart of a method for replacing a pipe pipe on an ondol floor using a cutting method according to another embodiment of the present invention, and FIG. 4 is a cross-sectional view of the installation according to FIG. 3.

As shown in FIG. 1, the method of replacing the pipe pipe on the ondol floor using the cutting method is a position indication step of displaying the existing pipe pipe in the center and spaced at both sides by a preset distance and displayed side by side on the plastering mortar layer (S100). ), and a cutting step (S110) of cutting the plastering mortar layer with a cutter device including a double cutter along the line marked side by side, and after the cutting step, the existing pipe pipe is removed, and the existing pipe pipe is The step of forming an incision groove to a predetermined depth at the removed position (S120), the step of applying an insulating waterproofing agent along the inner side of the incision groove (S130), and the step of seating and installing the new pipe pipe (S140), It includes a mortar filling step (S150) of filling and filling the incision groove in which the pipe pipe is seated, and a finishing step (S160) by placing a plastering mortar layer on the surface of the filled mortar.

First, in the location indication step (S100), if the location of the existing piping pipe 10 that needs to be replaced is difficult to check with the naked eye, hot water is put into the existing piping pipe 10 to detect the pipeline by heat detection or move the piping. In the case of metal such as pipes, the location of the existing piping pipe 10 is accurately located using a metal detector.

This is to avoid deterioration of work efficiency due to factors such as wear of work tools and work obstruction caused by the matching of the working position with the existing piping pipe 10, in order to avoid the existing piping and make it advantageous for construction, When the existing piping pipe 10 is even, the location of the existing piping pipe is accurately dug to remove the old piping and new piping to protect the floor surface of the building and prevent heat leakage along the existing piping after piping. This is because it can prevent this decrease.

When the location of the existing piping pipe 10 is accurately identified as described above, as shown in FIG. 2A, the plastering mortar layer 200 at a location spaced approximately 1 to 2 cm from both sides with the existing piping pipe 10 in the center. The location is marked through an ink line.

That is, the existing piping pipe 10 is spaced apart from the center and a straight line is displayed side by side.

And in the cutting step (S110), as shown in FIG. 2B, the plastering mortar layer 200 is cut with the cutter device 110 including the double cutter 116 along the line marked side by side.

Here, the cutter device 110 is disposed on the main body 112 having the handle 114 formed on the upper surface and the lower surface of the main body 112, and is installed inclined to form a certain angle with respect to the ground, and the two motors 118 Two double cutters 116 installed to be driven by each are installed.

The double cutters 116 are positioned to face each other, but are installed at an inward direction, and accordingly, the cutting of the plastering mortar layer 200 may be made at an angle.

When the incision is made to some extent by the double cutter 116, the plastering mortar layer 200 is easily separated, and the existing piping pipe 10 is exposed and thus removed.

When the removal of the existing piping pipe 10 is completed, a step (S120) of forming the incision groove 300 to a predetermined depth as shown in FIG. 2C is performed.

The cut groove 300 may be preferably formed in a reverse trapezoidal shape by a double cutter 116 that is cut at an angle, and may be preferably formed deeper than the diameter of the pipe pipe 100 to be installed, and the cut groove 300 The bottom surface of the can be flat.

A separate device may be required for the formation of the incision groove 300, but the type of equipment is not largely limited, and any type of equipment capable of cutting and digging the bottom surface may be used, and a wheel attached to the equipment without installing a rail It can be moved to, but then it is difficult to work in a straight line, so using a guide rail is more effective. It is also possible to use a hand grind or a hand drill that is not specialized equipment. And the rail that guides the linear movement of equipment is also irrelevant if it is an equipment that can guide the movement of H-beams or other equipment, which are widely used in the past. Further, in the incision groove 300, water is sprayed or applied on the existing bottom mortar layer with a brush to meticulously wet the area around the incision groove 300 to reinforce moisture, and an aqueous solution is applied to block the capillary pores of the existing mortar layer. This is to prevent moisture from being absorbed into the existing mortar layer.When water is first sprayed or applied with a brush so that the cut surface retains moisture, when filling and filling a new mortar around the pipe pipe, the moisture contained in the new mortar layer is added to the existing mortar layer. It blocks pores of the existing cement so that it cannot be absorbed.At this time, if too much water is sprayed or applied, the existing mortar layer will absorb and the remaining water may seep into the insulation layer and cause side effects. When applied, the water evaporates and dries before the new mortar is filled, so when the new mortar layer is filled, the aqueous solution does not function properly, and the moisture contained in the new mortar is absorbed into the existing mortar. It causes cracks between the new mortar.

Next, by applying an aqueous solution to the inner surface of the incision groove 300 of the existing mortar containing moisture by the above method, it blocks the capillary pores of the existing mortar layer, and when filling the incision groove 300 with a new mortar, a new mortar Water is not absorbed into the existing mortar layer, and the aqueous solution used at this time is a water-soluble aqueous solution that can block fine capillaries formed in the existing mortar layer or other water-soluble compounds that can be combined with the existing mortar layer. Both can be used, and if an adhesive is mixed and treated, the existing mortar layer and the new mortar layer are more completely bonded.

After the above process, the thermal insulation waterproofing agent 310 may be applied along the inner side of the incision groove 300 coated with the aqueous solution, or the thermal insulation waterproofing agent 310 may be applied directly without the above process.

As a step (S130), shown in Figure 2d, the insulating waterproofing agent 310 may be made of at least three layers, preferably the top coat corresponding to the top, 50-70 parts by weight of a room temperature curing silicone rubber stock solution, Polyurethane resin 10-15 parts by weight, dichlorodimethylsilane (Dichlorodimethylsilane) 0.1-5 parts by weight is included, and the intermediate degree below it is an acrylic copolymer emulsion resin and a polyurethane emulsion resin in a weight ratio of 1:1. Mixed high elastic emulsion resin 40-52 midrang; 12-20 parts by weight of calcium carbonate; 2-4 parts by weight of thickener; 0.5-3 parts by weight of a dispersant; 0.5-2 parts by weight of antifoam; 0.5-2 parts by weight of preservative; 1-5 parts by weight of white carbon; It may contain 10-15 parts by weight of ceramic microspheres as a thermal insulation increasing agent.

And the undercoat acting as an adhesive in the lower half of the middle is 10 to 30 parts by weight of polyester, 10 to 20 parts by weight of silica, 5 to 10 parts by weight of iron oxide, 0.1 to 0.2 parts by weight of zinc phosphate, 5 to 10 parts by weight of isohexadecane Can include.

Here, the highly elastic emulsion resin is added to impart elasticity, and a mixture obtained by mixing an acrylic copolymer emulsion resin and a polyurethane emulsion resin in a weight ratio of 1:1 may be used, but is not limited thereto.

In particular, the acrylic copolymer emulsion resin forms a film on the surface to be coated and fills the voids to increase watertightness, and the polyurethane emulsion resin increases the adhesive strength to increase the adhesion strength, thereby maintaining the firm fixability while maintaining the elastic coating properties. do.

To this end, it should be added in the above composition ratio, but if it is added in less than 40 parts by weight, the elastic effect and watertightness decrease, and if it exceeds 52 parts by weight, the compressive strength and binding property are greatly increased, so that the coatability and blendability are decreased. Must be limited.

The calcium carbonate is added to increase film formation, and because it is water-soluble, it penetrates into cracks as well as areas where repair is uneven, thereby further maximizing waterproofness. In addition, it has a function of adjusting the thickness of the coating film.

However, in order to prevent viscosity decrease due to dilution during mixing, it should be added within the range of 12-20 parts by weight as described above.

The thickener is for controlling viscosity and preventing precipitation, and an inorganic thickener such as a clay mineral such as magnesium or silicate is preferable, and 2-4 parts by weight may be added.

The dispersant is added to facilitate dispersion of additives in the manufacturing process of the paint, and generally various surfactants are mostly used, and 0.5-3 parts by weight may be added.

The antifoaming agent is added to keep the coated surface smooth by not only suppressing the generation of bubbles during high-speed stirring, but also preventing pinholes generated by bubbles after application, and alcohol or organophosphate is preferable. Used, but is not limited thereto.

The preservative is to prevent or inhibit spoilage, and methylparaben is preferred.

The white carbon is a thixotroping agent for imparting thixotropy, and is added to minimize deformation or denaturation of the surface of the coating film.When added in an excessive amount, the viscosity increases, and when added in a small amount, the function becomes ineffective. Should be added as.

The heat insulating property increasing agent is preferably a micron-sized micron-sized hollow body powder (commonly referred to as'insulation pad') containing aluminum silicate as a main component, which is a volatile organic compound as well as harmful heavy metals having heat shield heat reflection and heat resistance of the closed air layer. And it is an environmentally friendly material without any toxicity.

Due to its excellent durability and heat resistance, it is used as a surface coating agent for space shuttles by NASA due to its excellent solar radiation heat blocking performance. Due to the structural characteristics of forming a vacuum inside with an independent cavity, that is, a closed cell structure It has high durability and temperature resistance, has strong resistance to moisture penetration, and forms an insulating layer with strong water and moisture resistance by forming an airtight skin on the surface, and has a very strong effect against acids and alkalis, so it has excellent chemical resistance. As the main material and molecular structure have a chemically very safe structure, the lifespan is semi-permanent, making it suitable as an insulation material.

And in the step (S140) in which the new pipe pipe 100 is seated and installed in the cut groove 300, the size of the inverted trapezoid cut groove 300 is larger than the outer diameter of the pipe pipe 100 to be installed, and the depth is also formed. As a result, the piping pipe 100 is easily installed along the incision groove 300.

Here, as shown in FIGS. 3 and 4 according to another embodiment of the present invention, after mounting the piping pipe 100, the piping pipe 100 is separated from the bottom surface of the cut groove 300 and plastering An installation step (S145) of the mounting fixing means 320 may be further included in order to increase the thermal conductivity of the mortar layer 200 as a whole.

The mounting fixing means 320 is preferably a metal material having good thermal conductivity, and a plurality of the mounting fixing means 320 may be installed at a predetermined distance along the pipe pipe 100 installed along the cut groove 300.

The mounting fixing means 320 includes a fixture 322 capable of including a circular pipe pipe 100 inside, and a fixing plate integrally formed on the upper side of the fixture 322 and supported by the cut groove 300 ( 324).

And in the mortar filling step (S150) of filling and filling the incision groove 300 on which the pipe pipe 100 is seated, as shown in Fig. 2e, cement is put in the incision groove 300 in which the pipe pipe 100 is installed, Fill before starting the hardening action.

At this time, it should be noted that it is important to fill the incision groove 300 before the cement hardens. Finally, in FIG. 2F, a plastering mortar layer 200 is poured on the surface of the filled mortar to include a finishing treatment step (S160).

The plastering mortar layer 200 is carried out along the incision groove 300, and before the cement filled in the incision groove 300 is completely hardened, the surface is smoothly finished with a metal plastering knife or a spatula. If there is any roughness, it is finished by grinding the surface with an abrasive stone or other abrasive after it is completely hardened. Due to the functions as described above, by replacing the pipe pipe by cutting only the part where the existing pipe is buried, it is possible to prevent the risk of cracking or damage of the building, and the construction is simple and the installation cost is low.

In addition, heat loss can be reduced while heating efficiency can be improved by installing an insulating means in the cut grooves cut through the cutting method.

In addition, maintenance is easy even after replacement of new piping pipes.

Although specific embodiments have been described in the detailed description of the present invention, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention is limited to the described embodiments and should not be determined, and should be determined by the scope of the claims and equivalents as well as the scope of the claims to be described later.
