Meanwhile, the present invention may further include a heating unit as another example.

7 and 8 , the heating unit 70 is coupled to the first reinforcing bar 40 and serves to conduct heat to the first reinforcing bar 40 .

The heating unit 70 is positioned between the first reinforcing bar portion 40 and the second reinforcing bar portion 50 and is formed on the inner surface of the foam panel 71 surrounding the inner formwork 20 and the foam panel 71 . A hot water pipe 73 inserted into the insertion groove and a heat sink 75 coupled to the inner surface of the foam panel 71 to contact the hot water pipe 73 and fixed to the first reinforcing bar 40 are provided.

The heat sink 75 is formed to surround the inner mold 20 once. The heat sink 75 is vertically spaced apart and installed in two parts. The heat dissipation plate 75 is fixed to the outside of the first reinforcing bar 40 and is in direct contact with the first reinforcing bar 40 . Although not shown, the heat sink 75 may be welded to and fixed to the first reinforcing bar 40 or may be fixed to the first reinforcing bar 40 by a wire or a fixing tool.

The heat sink 75 receives heat from the hot water pipe 73 and spreads it widely to discharge heat. When heat is released from the heat sink 75, heat is conducted through the first reinforcing bar 40 in all directions, up, down, left and right, and the heat surrounds the inner formwork, thereby enhancing the heating effect.

The heat sink 75 is formed of a metal material having excellent thermal conductivity. For example, the heat sink 75 may be formed of a copper plate.

The foam panel 71 is coupled to the heat sink 75 and is formed to surround the inner mold 20 once. The foam panel 71 is coupled to the outer surface of the heat sink 75 .

The hot water pipe 73 is formed of a flexible synthetic resin material. The hot water pipe 73 is connected to the pipe of the boiler. The water heated in the boiler moves along the ounce tube 73 and circulates to radiate heat to the heat sink 75 .

The hot water pipe 73 preferably has a rectangular cross-section rather than a circular one. In the case of the rectangular hot water pipe 73 , since one side is all in contact with the heat sink 75 , the contact area with the heat sink 75 is greatly improved. Accordingly, it is possible to increase the heat transfer effect by conduction.

The above-described heating unit 70 is embedded in the wall of the dome house. Therefore, heat can be generated from the walls of the dome house, so the heating and insulation effect of the dome house is excellent.

And as shown in FIG. 9 , rectangular inlet grooves are formed at regular intervals in the heat sink 75 , and coupling protrusions 77 inserted into the inlet grooves may be formed on the inner surface of the foam panel 71 .

And an adhesive tube 80 is installed at the end of the coupling protrusion 77 . The adhesive tube 80 is formed of rubber having elasticity so that it can be deformed by compression. The inside of the adhesive tube 80 is filled with a binder 81 . As the binder 81 , a conventional polymer binder in a liquid or paste state or a silicone resin for sealing may be used.

One or two or more discharge slits 83 cut in a straight line are formed on the side of the adhesive tube 80 . Since the adhesive tube 80 is made of an elastic material, the discharge slit 83 is normally closed. When the coupling protrusion 77 is inserted into the inlet groove, the adhesive tube 80 is pressed against the heat sink 75 , and when the adhesive tube 80 is compressed, the discharge slit 83 is opened while being crushed. Accordingly, the binder 81 filled in the adhesive tube 80 flows out through the discharge slit 73 , and the discharged binder 81 is cured while filling the gap between the coupling protrusion 77 and the heat sink 75 . do. Accordingly, the foam panel 71 and the heat sink 75 may be firmly coupled.

Another example of the heating unit is shown in FIG. 10 .

Referring to FIG. 10 , the heating unit 90 includes a foam panel 71 , a heat storage sheet 91 coupled to an inner surface of the foam panel 71 and having a plurality of cells 92 therein, and cells 92 . ), a phase change material 93 that is filled in and absorbs or emits latent heat due to a phase change, a ceramic panel 95 coupled to the inner surface of the heat storage sheet 91, and an inner surface of the ceramic panel 95 . The hot water pipe 73 inserted into the insertion groove formed in the A heat sink 75 in contact with the first reinforcing bar is provided so as to be inverted.

The heating part shown in FIG. 10 is different from the heating part of FIG. 8 in that the heat storage sheet 91 and the ceramic panel 95 are further formed between the foam panel 71 and the heat sink 75 .

The configuration of the heating unit 90 shown in FIG. 10 will be described in detail.

The heat sink 75 is formed to surround the inner formwork once. As shown in FIG. 8 , the heat sink 75 is fixed to the outside of the first reinforcing bar 40 and in direct contact with the first reinforcing bar 40 . The heat sink 75 may be fixed to the first reinforcing bar by welding, or may be fixed to the first reinforcing bar by a wire or a fixing tool.

The heat sink 75 receives heat from the hot water pipe 73 and spreads it widely to discharge heat. When heat is released from the heat sink 75, heat is conducted through the first reinforcing bar in all directions, up, down, left and right, and the heat surrounds the inner formwork, thereby enhancing the heating effect.

The heat sink 75 is formed of a metal material having excellent thermal conductivity. For example, the heat sink 75 may be formed of a copper plate.

The ceramic panel 95 is coupled to the outer surface of the heat sink 75 . Accordingly, the heat sink 75 is positioned on the inner surface of the ceramic panel 95 .

The ceramic panel 95 may be formed by mixing a ceramic material such as pearlite having a porous structure with an inorganic binder and then molding the ceramic material into a plate shape. As the inorganic binder, loess dough or cement can be used. The ceramic panel 95 is light, has excellent strength, and has good thermal insulation properties.

An insertion groove into which the hot water pipe 73 is inserted is provided on the inner surface of the ceramic panel 95 . The hot water pipe 73 is formed of a flexible synthetic resin material. The hot water pipe 73 is connected to the pipe of the boiler. The water heated in the boiler moves along the ounce tube 73 and circulates to radiate heat to the heat sink 75 .

The hot water pipe 73 has a rectangular cross section. In the case of the rectangular hot water pipe 73 , since one side is all in contact with the heat sink 75 , the contact area with the heat sink 75 is greatly improved. Accordingly, it is possible to increase the heat transfer effect by conduction.

The heat storage sheet 91 is coupled to the outer surface of the ceramic panel 95 . Accordingly, the ceramic panel 95 is positioned on the inner surface of the heat storage sheet 91 .

The heat storage sheet 91 may be formed of a synthetic resin material. The heat storage sheet 91 has a plurality of cells 92 formed therein. In the illustrated example, the cell 92 is formed in an elliptical shape. The cell 92 is filled with a phase change material 93 .

A phase change material (PCM) is a material that accumulates a large amount of thermal energy (latent heat) or releases stored thermal energy through a phase change process into a solid or liquid. A phase change material absorbs or releases latent heat in an isothermal state during a phase change between a solid state and a liquid state. Since the phase change material that stores thermal energy by such a phase change absorbs or releases latent heat, it can store a larger amount of thermal energy than a general thermal storage material. The phase change material absorbs and stores heat when it rises above the phase change temperature, that is, the melting point, and releases the stored heat when it goes below the melting point.

In summer, when the phase change material 93 rises above the phase change temperature by heat transferred from the outdoors, it undergoes a phase change, and at this time, it absorbs the latent heat required for the phase change, effectively blocking the transfer of external heat to the inside.

A typical organic material having a large latent heat may be used as the phase change material. Preferably, a phase change material having a melting point (phase change temperature) of 30 to 40°C is used. As such a phase change material, nonadecane or eicosane may be used.

The foam panel 71 is coupled to the outer surface of the heat storage sheet 91 . Accordingly, the heat storage sheet 91 is positioned on the inner surface of the foam panel 71 . The foam panel 71 is preferably formed of a foamed resin having excellent thermal insulation. Expanded polypropylene (EPP) may be used as the foaming resin.

The above-described heating unit 90 is located between the first reinforcing bar and the second reinforcing bar. Therefore, when concrete is injected into the space between the inner formwork and the outer formwork and cured to produce a dome house, the heating part is embedded in the wall of the dome house. Therefore, heat can be generated from the walls of the dome house, so the heating and insulation effect of the dome house is excellent.
