As shown in FIG. 1, the method of constructing a house using the PC method according to the present invention includes a foundation floor construction step S10, a side wall construction step S20, a slab construction step S30, and a roof construction step S40 .

As shown in FIG. 2, the foundation floor construction step S10 is a step of flattening the floor surface through the reinforced concrete structure. At this time, the foundation floor 100 reinforces and strengthens the floor surface, It is preferable to configure it to be stably supported on the ground.

The side wall construction step S20 is configured to install the side wall by fixing the wall panel 200 to the concrete foundation floor 100 as shown in FIG.

As a method of fixing the wall panel 200 to the concrete foundation floor 100, various conventional techniques can be applied. For example, as shown in the figure, the head portion of the 'T' shaped reinforcing bar 110 And the wall panel 200 is disposed to be supported on one side of the reinforcing bar 110 and then welded or bolted between the concrete base floor 100 and the wall panel 200 and the reinforcing bar 110 So that they can be bound together through the fastening method.

However, in the present invention, the wall panel 200 is produced by a PC (precast concrete) method from a factory to a unit wall panel 200, and a plurality of wall panels 200 Can be assembled in the field to construct the side walls.

2, the slab construction step S30 is performed by supporting the slab panel 300 at the upper end of the wall panel 200 and then by various combinations between the wall panel 200 and the slab panel 300 The slab panel 300 may be a PC panel in which reinforcing bars 310 are laid out as shown in FIG.

2, the plurality of roof panels 400 are configured to be supported over at least two roof beams 410. The roof beams 410 and the roof beams 410 are installed on the roof beams 410, The roof panel 400 may also be manufactured from a unit roof beam 410 and a unit roof panel 400 at a plant through a PC (precast concrete) method, and a specific coupling method thereof will be described later.

Hereinafter, the wall panel 200, which is an embodiment of the present invention, will be described with reference to FIG.

As described above, the wall panel 200 according to the present embodiment is manufactured by a PC method and includes a concrete part 210 and a heat insulating material 220.

In the present invention, although not shown in the drawings, when a general primer is used in adhering the heat insulating material 220 to the concrete part 210, the concrete part 210 is not filled tightly with micro cracks and curvature The gap between the primer and the concrete portion 210 is reduced by the gap between the primer and the concrete portion 210 due to the problem that the adhesive force of the heat insulating material 220 is lowered due to the gap between the concrete portion 210 and the concrete portion 210, And a deterioration problem of the concrete part 210 due to the contained gas.

The primer of the present example contains 40 to 60 parts by weight of silica sand, 5 to 15 parts by weight of oxides, 3 to 8 parts by weight of distearmonium hectorite, and 1 to 5 parts by weight of titanium dioxide-containing porous fibers per 100 parts by weight of the resin , And a hardening material and an additive comprising 30 to 60 parts by weight of an SBR latex, 20 to 40 parts by weight of an EVA bonding agent and 5 to 10 parts by weight of sodium benzonite with respect to 100 parts by weight of water in which fine bubbles are dissolved . In addition, the additive is characterized in that 60 to 80 parts by weight of D-mannose and 60 to 80 parts by weight of lithium hydroxide are contained in 100 parts by weight of sodium thiosulfate pentahydrate.

In other words, the main material is made by mixing silica, oxide and the like as an inorganic material, and the setting material is a water-soluble liquid type mixed with S.B.R. latex, E.V.A, and sodium benzonite. The primer of the present embodiment is prepared by mixing the base material having the above-described constituents and the curing material to improve the filling property by microcracking and bending of the concrete part 210 and to control the crack in the curing process of the primer itself, So as to firmly take the adhesive force.

In the first place, a water-soluble resin is used as the resin. Preferably, the polyurea resin can be used as the water-soluble resin. The polyurea resin has chemical properties such as water resistance, chemical resistance and flame resistance and mechanical properties such as abrasion resistance and impact resistance As a resin having excellent properties, it is water-soluble and has environment-friendly properties harmless to the human body.

Disteardimonium hectorite is used as a thickener in the above-mentioned prescription. When a common thickener is used, a thickening effect is generated early in the course of stirring the above components, Uniformity can not be ensured. Particularly, filling property is decreased and sufficient filling is not performed to the microcracks and bending of the concrete portion, so that the adhesion force can be reduced and the durability of the concrete portion can be deteriorated.

Distearimonium hectorite is used as a thickening agent. Distearimonium hectorite is a common thickening agent, unlike methylcellulose (MC) or the like, and does not exhibit an immediate thickening effect when a composition material is mixed, The time point at which the thickening effect appears is somewhat delayed because it shows a thickening effect after a certain time.

In other words, distearmonium hectorite provides a stirring time so that mixing of the other ingredients can be uniformly performed, and when the mixture is sufficiently mixed, viscosity is developed during coating, uniform mixing is achieved and microcracks and bending are formed It is possible to uniformly and tightly fill the concrete surface, thereby improving the adhesion strength and durability.

The titanium dioxide-containing porous fiber is added to the titanium oxide-containing porous fiber to physically improve the crack resistance by the crosslinking action of the fiber. The fiber is made porous to function as a fault layer. will be. Further, the titanium dioxide-containing porous fiber contains titanium dioxide, so that the organic material incorporated in the composition can be decomposed.

Such a titanium dioxide-containing porous fiber can be produced by a known method, for example, after mixing a polymer precursor and a solvent, dispersing titanium dioxide (TiO2) in the polymer precursor into the mixture, So as to be made into fibers. The fibers thus produced are oxidized and carbonized to finally be made into porous fibers containing titanium dioxide.

On the other hand, water is mixed with the curing material. In this embodiment, water is mixed with dissolved microbubbles. Here, the smaller the diameter of the fine bubble, the more effective it is.

As the water in which the minute bubbles are dissolved is mixed, the water containing the above-mentioned compositions and the minute bubbles is generated into the bubbles in the paste by stirring or the like in the mixing process.

That is, even if a chemical bubble entraining agent is not used, a larger amount of bubbles are generated in the paste and uniform stirring is performed. In addition, the paste is hardened in a state where a large amount of minute bubbles exist in the paste, .

In addition, the micro-bubbles prevent the curing reaction of the paste from being inhibited by the organic substances by decomposing the organic substances incorporated in the above-mentioned compositions, thereby improving the physical properties. As the organic substances are decomposed in the paste, the space in which the organic substances exist is cured So that the heat insulating property is further doubled by the empty space.

That is, heat transfer between the concrete part and the heat insulating material can be controlled by the heat insulating property so that the expansion stress can be controlled between the materials of the heterogeneous material. The water in which the minute bubbles are dissolved can be produced by various known techniques, so that the description thereof is omitted.

The reason why sodium thiosulfate pentahydrate (Na ₂ S ₂ O ₃ .O 5 H ₂ O) is included as the composition of the additive is to improve the resistance against the salt inflow from the outside. The sodium thiosulfate pentahydrate controls the chlorine content by the following reaction mechanism.

Cl ₂ + Na ₂ S ₂ O ₃ ㅇ 5H ₂ O + H ₂ O → Na ₂ SO ₄ + 2HCl + S + 5H ₂ O

Such sodium thiosulfate pentahydrate exhibits neutrality at a pH of about 6.5 to 8.0, thereby removing chlorine without causing acidification of the paste, thereby improving resistance to salt.

However, since sodium thiosulfate pentahydrate is likely to liberate sulfur (S) by self-reduction as shown in the above reaction mechanism, the liberated sulfur may cause harmful gas in the form of hydrogen sulfide (H ₂ S) Or may have a deleterious effect on the human body due to toxicity upon spillage.

To control this, D-manus is included. Hydrogen sulfide is a substance having odor and toxicity, which is deteriorated by the mechanism of D-mannose and detoxifies hydrogen sulfide.

On the other hand, in the case of the primer of the present embodiment, in order to improve the filling property and heat resistance, water having dissolved microbubbles is added but not mentioned above.

However, the air introduced into the air bubbles flows out into the paste due to the blending of the air bubbles discharged after the compounding, application and application. Especially, when carbon dioxide flows out, a carbon dioxide film is formed between the concrete part and the heat insulating material, There is a problem that can be a point that can cause a problem.

In the case of carbon dioxide flowing out of the bubbles due to the addition of lithium hydroxide as described above, the lithium hydroxide fixes the carbon dioxide, thereby controlling the cause of the neutralization of the concrete part.

The concrete part 210 is constructed such that reinforcing bars 212 are longitudinally and horizontally arranged inside the concrete part 210 and the heat insulating material 220 is attached to the outer surface of the concrete part 210.

Here, the outer surface of the concrete part 210 means a surface exposed to the outside when the house is constructed, and the inner surface of the concrete part 210 or the wall panel 200 means an opposite surface It means.

As described above, the wall panel 200 can be manufactured in a state where the heat insulating material 220 is attached to the concrete part 210 in which the reinforcing bars 212 are placed in the factory, and can be supplied to the site.

Hereinafter, an embodiment of the side wall construction step S20, which is a process of the present invention, will be described with reference to FIG.

As shown in the drawing, the side wall construction step S20 according to the present embodiment further includes a straight line construction step S21 and a corner section construction step S22.

The straight section construction step S21 constructs the outer wall of the straight section using the wall panel 200. Each of the plurality of unit wall panels 200 has its lower end fixed to the concrete foundation floor 100, And the side wall is installed by fastening the side surface between the wall panels 200.

In the corner section construction step S22, the outer wall of the corner section is constructed by using the wall panel 200. Specific embodiments thereof will be described below.

Meanwhile, in this specification, the side wall may include an outer wall of a house, and an inner partition wall corresponding to a boundary surface of a room, a living room, a toilet, etc. inside the house.

In this case, the inner surface of the wall panel 200 refers to the opposite surface of the surface on which the heat insulating material 220 is attached to the concrete part 210, as mentioned above.

Therefore, as shown in FIGS. 7A and 7B, in the wall panels 200, when only the inner ends of the concrete portions 210 are in contact with each other, the overlap portions of the exposed reinforcing bars 213 overlap each other, In addition, each exposed reinforcing bar 213 is not shown, but may be crossed in various forms.

In addition, the longitudinal reinforcement step S223 is performed in the longitudinal direction for each corner of the exposed reinforcing bars 213 intersected in the 'ㅁ' shape in the arrangement step S221 of the corner section wall panel 200, Each of the wall panels 200 has a more rigid fastening structure, and the rigidity can be doubled by the following concrete pouring.

In this case, the auxiliary heat insulating material 230 may be attached to the heat insulating material 220 attached to the wall panel 200. In some cases, the auxiliary insulating material 230 Can be integrally formed with the heat insulating material 220.

According to the above-described structure, since the auxiliary insulating material 230 acts as a formwork, it is not necessary to construct a separate formwork, and as a result, the air is reduced as a whole and the robustness is improved.

Thereafter, in the concrete pouring step S224, the concrete is poured into the closed space 240, and the construction of the corner section is completed through the concrete curing process.
