Brief explanation of the drawing

[0023] FIG. 1 is a cross-sectional view of the heating floor of the present invention. FIG. 2 is a flowchart of the construction method of the heating floor of the present invention. Specific details for implementing the invention

[0024] Hereinafter, the most preferred embodiment of the present invention is described in detail so that a person skilled in the art to which the present invention pertains can easily practice the present invention.

[0025] The numbers cited in the following embodiments are not limited to the subjects of citation but may be applied to all embodiments. Subjects that exhibit the same purpose and effect as the configuration presented in the embodiments correspond to equivalent substitute subjects. The higher-level concepts presented in the embodiments include subjects of lower-level concepts that are not described.

[0027] [Example 1-1] The present invention relates to a heating floor for a building, and specifically comprises a structural layer (100) that forms a flat slab (110) between beams of a building; an insulating layer (200) located on the upper surface of the structural layer and having an insulating material (210) formed thereon; a heating layer (300) located on the upper surface of the insulating layer and having heat emitted therefrom; a surface layer (400) located on the upper surface of the heating layer and having a surface formed by mortar (410); and a finishing layer (500) located on the upper surface of the surface layer and having a surface formed by a finishing material.

[0029] Embodiment 1-1 of the present invention relates to a building heating floor structure for improving indoor heating efficiency of a building. The heating floor of a building has a slab (110) formed in a flat plane between beams of the building as a structural layer (100), and the structural layer (100) serves as a base layer that supports the load of the building and performs the role of supporting the entire heating floor.

[0030] An insulation layer is formed on the upper surface of the above structural layer (100), and an insulation material (210) is placed in the insulation layer. The insulation layer (200) blocks heat loss to the lower part of the slab and is intended to improve heating efficiency.

[0031] A heating layer (300) that emits heat is formed on the upper surface of the insulation layer (200). The heating layer (300) includes a heating pipe or a heating element. The heating pipe supplies heat by flowing hot water and steam, and it is preferable that the heating element emits heat by means of a heating pad.

[0032] Mortar (410) is poured onto the upper surface of the heating layer (300) to form a surface layer (400). The surface layer (400) protects the heating layer (300) and also serves to uniformly distribute heat. Additionally, it ensures the flatness of the floor, thereby facilitating the construction of the upper finishing layer.

[0033] A finishing layer is formed on the upper surface of the surface layer (400), and the finishing layer is constructed using a finishing material. The finishing layer (500) is a layer that completes the appearance of the floor, and tiles, wood, stone, or other floor finishing materials may be applied, and is formed to be suitable for the user's walking and living environment.

[0036] [Example 2-1] The present invention relates to a heating floor for a building, and in Example 1-1, the insulation layer is composed of a structure including the use of an organic and / or inorganic insulation board.

[0037] [Example 2-2] The present invention relates to a heating floor for a building, and in Example 2-1, the organic insulation board is formed from any one selected from polystyrene-based, polyurethane-based, polyethylene-based, and phenolic-based materials.

[0038] [Example 2-3] The present invention relates to a heating floor for a building, and in Example 2-1, the polystyrene-based material is formed from expanded polystyrene (EPS) or expanded polystyrene (XPS).

[0039] [Example 2-4] The present invention relates to a heating floor for a building, and in Example 2-1, the polyurethane system comprises being formed from a rigid polyurethane (PU) foam or a polyisocyanurate foam (PIR).

[0040] [Example 2-5] The present invention relates to a heating floor for a building, and in Example 2-1, the polyethylene-based material is formed from expanded polyethylene (PE) foam.

[0041] [Example 2-6] The present invention relates to a heating floor for a building, and in Example 2-1, the phenolic material is formed from phenolic foam (PF).

[0042] [Example 2-7] The present invention relates to a heating floor for a building, and in Example 2-1, the inorganic material is formed from any one selected from glass wool, rock wool, perlite, vermiculite, calcium silicate board, and aerogel;

[0043] [Example 2-8] The present invention relates to a heating floor for a building, and in Example 2-1, includes a heat-insulating pad (220) formed on one surface of the insulation board and blocking heat.

[0045] Examples 2-1 to 2-8 of the present invention embody an insulation layer. The insulation layer utilizes an organic insulation board and / or an inorganic insulation board. This may form a single insulation layer or multiple insulation layers may be installed in a superimposed manner. When multiple insulation layers are used, each layer may be superimposed with different materials and may also be superimposed with different thicknesses. The insulation board serves to improve heating efficiency by blocking heat loss to the floor below.

[0046] The above organic insulation board may be formed from any one selected from polystyrene-based, polyurethane-based, polyethylene-based, and phenolic-based materials. In the case of a polystyrene-based insulation board, it may be formed from expanded polystyrene (EPS) or expanded polystyrene (XPS) to simultaneously ensure lightweight properties and thermal insulation performance.

[0047] In addition, polyurethane-based insulation boards can be formed from rigid polyurethane (PU) foam or polyisocyanurate (PIR) foam, providing relatively high thermal insulation performance and structural stability.

[0048] Polyethylene-based insulation boards are formed from expanded polyethylene (PE) foam, ensuring cushioning and ease of installation. Additionally, phenolic-based insulation boards are formed from phenolic foam (PF), providing excellent heat resistance and flame retardancy. Meanwhile, the inorganic insulation boards may be formed from any one selected from glass wool, rock wool, perlite, vermiculite, calcium silicate board, or aerogel. These inorganic insulation boards have excellent fire resistance and dimensional stability.

[0049] In another embodiment, a heat shielding pad (220) is formed on one side of the insulation board to suppress radiative heat transfer. The heat shielding pad (220) reflects or blocks heat transferred through the insulation layer, thereby allowing heating heat to be efficiently transferred upward, further improving overall heating performance.

[0052] [Example 3-1] The present invention relates to a heating floor for a building, and in Example 1-1, the heating layer is composed of a heating pipe (310) formed in the insulation layer; and a supporting aggregate (320) formed from a mixture of inorganic and organic aggregates and accommodating the heating pipe.

[0053] [Example 3-2] The present invention relates to a heating floor for a building, and in Example 3-1, the inorganic aggregate is formed of glass aggregate (321), and the organic aggregate is formed of polymer granular aggregate (322).

[0054] [Example 3-3] The present invention relates to a heating floor for a building, and in Example 3-2, the glass aggregate and polymer granular aggregate are formed to have the same or different sizes.

[0055] [Examples 3-4] The present invention relates to a heating floor for a building, and in Example 3-1, includes a tie (340) that connects the heating pipe to the insulation side.

[0056] [Example 3-5] The present invention relates to a heating floor for a building, and in Example 3-2, the glass aggregate is formed by a chronological procedure of: a crushing step (S11) for crushing glass; a melting step (S12) for melting the crushed glass after the crushing step; a molding step (S13) for molding the molten glass into a sphere after the melting step; and a sorting step (S14) for sorting the size of the sphere-shaped glass after the molding step.

[0058] Examples 3-1 to 3-5 of the present invention embody a heating layer. The heating layer is formed on top of an insulating layer and is intended for heat dissipation for heating. The heating layer forms a heating pipe (310) disposed on the insulating layer, accommodates the heating pipe, and includes a supporting aggregate (320) for supporting a load.

[0059] The above supporting aggregate has the purpose of uniformly distributing the load and accommodating and diffusing the heat from the heating pipes.

[0060] The above support aggregate (320) is composed of a mixture of inorganic aggregate and organic aggregate, and particularly by filling the area layer where the heating pipe (310) is located, it performs the role of stably maintaining the position of the pipe and effectively dispersing the heat transferred to the upper side.

[0061] This prevents the heating pipes from rising or sagging locally. Additionally, heat is absorbed by the pores located between the aggregates, or the aggregates themselves have the effect of absorbing heat. It is preferable that the inorganic aggregate be formed from glass aggregate (321). It is preferable that the organic aggregate be formed from polymer granular aggregate (322).

[0062] Glass aggregate (321) has excellent thermal conductivity, contributing to the rapid transfer of heat generated from the heating pipe, and polymer granular aggregate (322) provides lightness and cushioning properties, which is advantageous for controlling the density of the entire support aggregate and protecting the pipe.

[0063] At this time, the sizes of the glass aggregate (321) and the polymer granular aggregate (322) may be formed to be the same, or different sizes as needed. By adjusting the size of the aggregates, the filling properties, porosity, and heat transfer characteristics of the support aggregates can be adjusted to suit the design purpose.

[0064] Additionally, the heating pipe (310) can be connected to the insulation layer side through a tie (340). The tie (340) secures the heating pipe to the insulation layer, thereby preventing displacement during pipe installation and ensuring that the heating pipe remains stable even during the process of pouring support aggregate.

[0065] In another embodiment, the heating pipe can be connected to the groove and protrusion formed in the insulation layer by replacing the tie.

[0066] Meanwhile, the glass aggregate (321) is preferably made from recycled glass and can be manufactured through a time-series procedure including a crushing step (S11) for crushing the glass, a melting step (S12) for melting the crushed glass, a molding step (S13) for molding the molten glass into a sphere, and a sorting step (S14) for sorting the size of the sphere-shaped glass. Through such a manufacturing process, glass aggregate with uniform particle size and stable shape can be obtained, which contributes to improving the filling capacity and heat transfer performance of the heating layer.

[0069] [Example 4-1] The present invention relates to a heating floor for a building, and in Example 3-1, it is composed of a heat dispersion net (330) that is in contact with the heating pipe and is formed as a mesh net.

[0070] [Example 4-2] The present invention relates to a heating floor for a building, and in Example 4-1, the heat dispersion mesh is formed of metal.

[0071] [Example 4-3] The present invention relates to a heating floor for a building, and in Example 4-2, the metal is formed of aluminum or copper.

[0073] Examples 4-1 to 4-3 of the present invention embody a heat dispersion mesh. The heat dispersion mesh is positioned in contact with a heating pipe. The heat dispersion mesh (330) is formed in the form of a mesh and, since it is in direct contact with the heating pipe (310), rapidly and uniformly disperses the heat from the heating pipe. It is preferable that the material of the heat dispersion mesh (330) be formed of metal, and in particular, through the high thermal conductivity of the metal, it effectively diffuses the heat generated from the heating pipe throughout the heating layer.

[0074] Accordingly, localized heat concentration can be mitigated, and uniform heating performance can be secured across the entire floor. Additionally, the metal constituting the heat distribution mesh (330) may be formed of aluminum or copper. Aluminum provides both lightweight properties and excellent thermal conductivity, improving constructability and thermal efficiency. Copper has a higher thermal conductivity than aluminum, and thus enables rapid heat transfer.

[0077] [Example 5-1] The present invention relates to a heating floor for a building, and in Example 1-1, the mortar (410) is formed from 20 to 35 wt% cement (411), 60 to 75 wt% fine aggregate (412), 8 to 15 wt% water (413), and 0 to 3 wt% additive (414); the composition comprises these components.

[0078] [Example 5-2] The present invention relates to a heating floor for a building, and in Example 5-1, the additive is formed from a mixture of a water-reducing agent (414a), a shrinkage reducing agent (414b), and a fiber (414c).

[0079] [Example 5-3] The present invention relates to a heating floor for a building, and in Example 5-1, the particle size of the fine aggregate is formed to be 0.3 mm to 2.5 mm.

[0081] Examples 5-1 to 5-3 of the present invention describe a mortar for a surface layer. Since the mortar of the present invention forms the surface layer of a building slab, it must be possible to construct it with uniform flatness and ease. Additionally, it must not undergo dimensional changes during the curing process, must not produce errors such as cracks, and must serve the complex purposes of supporting loads and dispersing heat.

[0082] Accordingly, to implement this, it is composed of a mixture of cement, fine aggregate, water, and additives, and the additives may include water reducers, shrinkage reducers, and fibers depending on the purpose.

[0083] The above-mentioned water-reducing agent (414a) reduces the unit water content while maintaining the same fluidity to improve the density of the mortar, and the shrinkage-reducing agent (414b) suppresses cracks that may occur due to drying shrinkage and thermal shrinkage.

[0084] In addition, the fiber (414c) is dispersed within the mortar and improves the durability of the surface layer by controlling the progression of microcracks.

[0085] The above fine aggregate (412) is formed to have a particle size range of 0.3 mm to 2.5 mm. This particle size range of the fine aggregate tightly fills the upper and surrounding areas of the heating pipe, suppresses the occurrence of voids, and ensures that heat is transferred uniformly throughout the mortar.

[0086] In one embodiment, since the mortar must rapidly transfer heat from the heating pipes to the upper finishing layer, a composition with a lower porosity and superior filling properties than general floor plastering mortar is required. The mortar of the present invention improves heat transfer efficiency by limiting the particle size of the fine aggregate to 2.5 mm or less and reducing the unit water content through a water-reducing agent to form a dense structure.

[0087] In one embodiment, the mortar is required to have higher thermal fatigue resistance than general structural mortar. In the present invention, by including a shrinkage reducing agent and fibers, crack formation and delamination can be suppressed even in a repetitive thermal loading environment.

[0088] The mortar of the present invention can have its fluidity controlled to be suitable for both pumping and spraying applications, and can ensure uniform quality even in large-area floor heating applications by suppressing bleeding and material separation. This improves surface smoothness after application and facilitates the application of upper finishing materials.

[0091] [Example 6-1] The present invention relates to a method for constructing a floor heating system for buildings, and specifically comprises a step of cleaning the surface of a slab (S110); a step of forming a heating layer (S120) of mounting a heating pad on the surface of the slab after the cleaning step; a step of installing a heating pipe on one side of the heating pad after the step of forming the heating layer (S130); a step of pouring a support aggregate to be filled into the heating layer of Example 1-1 to accommodate the pipe after the step of installing the pipe (S140); and a step of pouring mortar after the step of pouring the support aggregate (S150).

[0092] [Example 6-2] The present invention relates to a method for constructing a heating floor in a building, and in Example 6-1, among the pipe installation steps, includes a pipe connection step (S131) ​​for connecting the heating pipe and the heating pad.

[0093] [Example 6-3] The present invention relates to a heating floor for a building, and in Example 6-1, the invention includes a support injection step (S141) in which the support is injected using an injection device during the support pouring step; and a leveling step (S142) in which the surface of the support is leveled after the support injection step.

[0094] [Example 6-4] The present invention relates to a heating floor for a building, and in Example 6-1, during the mortar pouring step, it includes a mortar spraying step (S151) in which the mortar is sprayed using a spraying device.

[0095] Embodiments 6-1 to 6-4 of the present invention relate to a method for constructing a floor heating system for construction, and are characterized by a chronological procedure comprising a substrate step, a heating layer formation step, a pipe installation step, a support casting step, and a mortar casting step. The construction method according to the present invention is configured to stably secure heating performance and construction quality by forming a heating structure on the upper surface of a slab in stages. First, a cleaning step (S110) is performed to clean the surface of the slab in order to remove dust, foreign substances, and residues present on the surface of the slab. After the cleaning step (S110), a heating layer formation step (S120) is performed to install a heating pad on the surface of the slab. The heating pad is a step intended to suppress heat loss downwards and support the heating pipes, and is placed on the upper surface of the slab to form a heating layer. After the heating layer formation step (S120), a pipe installation step (S130) is performed to install heating pipes on one side of the heating pad. Through the above pipe installation step (S130), the heating pipes are placed on the heating pad while maintaining a predetermined spacing, and are configured to enable uniform heat transfer across the entire floor.

[0096] delete

[0097] The above pipe installation step (S130) further includes a pipe connection step (S131) ​​for connecting the heating pipe and the heating pad together. Through the pipe connection step (S131), the heating pipe is stably fixed to the heating pad, thereby preventing displacement or damage to the pipe during subsequent processes. Next, after the pipe installation step (S130), a support casting step (S140) is performed to pour support aggregate that fills the heating layer of Example 1-1 to accommodate the heating pipe. The support aggregate fills around the heating pipe to support the pipe and serves to ensure that heat is uniformly transferred throughout the heating layer. During the support casting step (S140), a support spraying step (S141) may be performed to spray the support using a spraying device. This spraying method is advantageous for uniformly distributing the support aggregate around the pipe. In addition, after the support injection step (S141), a leveling step (S142) is performed to level the surface of the support, thereby facilitating the pouring of mortar in the upper process. Subsequently, after the support pouring step (S140), a mortar pouring step (S150) is performed to pour mortar. Through the mortar pouring step (S150), a surface layer is formed on top of the heating layer, and it performs the function of protecting the heating pipes and support aggregates and uniformly transferring heat upward.

[0098] During the above mortar pouring step (S150), a mortar spraying step (S151) in which mortar is sprayed using a spraying device may be included. This allows for the application of mortar with a uniform thickness even on large floor areas, thereby simultaneously improving construction efficiency and surface smoothness. Furthermore, the mortar spraying device may be identical to the support material spraying device. That is, it has the effect of spraying support aggregate from a single piece of equipment, followed by spraying mortar. If necessary, the support material and mortar may be mixed as a single unit and sprayed. According to this construction method, the present invention can achieve stable fixation of heating pipes, improved heat transfer efficiency, and uniformity of construction quality, thereby effectively improving the performance and durability of the building floor heating structure.
