Description

Module board with heat preservation, heat insulation and heat reflection functions for floor heating

Technical Field

The utility model relates to a warm up with module board that has thermal-insulated and heat reflection function that keeps warm belongs to the cold-proof technical field of building.

Background

The floor heating is short for floor radiation heating, the whole floor is used as a radiator, the whole floor is uniformly heated through a heating medium in a floor radiation layer, and the heating purpose is achieved by conducting from bottom to top by utilizing the law of heat storage and upward radiation of the floor. Compared with the traditional heating, the floor radiation heating has incomparable advantages, has the advantages of comfort, energy conservation, environmental protection and the like, and is not only largely used for public buildings such as civil houses, various medical institutions, swimming halls, gymnasiums, markets, office buildings and the like, but also largely used for heat preservation of building systems such as factory buildings, hangars, flower beds, football grounds, vegetable greenhouses and the like, and even used for snow melting of outdoor roads, roofs, stairs, airport runways and various industrial pipelines.

The water floor heating adopts a heating mode that hot water with the temperature not higher than 60 ℃ is used as a heat source and circularly flows in a coil system embedded under a floor to heat the whole floor and uniformly radiate and radiate heat indoors through the ground. The hot medium is divided into a water floor heating system and an electric floor heating system, the paving structure is divided into a wet floor heating system and a dry floor heating system, and the dry floor heating system does not need pea stone backfilling (belonging to an ultra-thin type); the surface decoration materials are divided into floor type floor heating and floor brick type floor heating.

The technology of water-floor heating and dry-type floor heating is mature and begins to be applied in a large area. Currently, there are two main product forms in the technical field: one is a polystyrene board module, and the other is an extruded sheet aluminum foil covered module. Although the first polyethylene polystyrene board module has a heat preservation and insulation function, the first polyethylene polystyrene board module does not have a reflection function, so that the application range of the first polyethylene polystyrene board module is greatly limited, and the first polyethylene polystyrene board module is only suitable for floor tile type decorative surface floor heating and is not suitable for wood floor type decorative surfaces. Mortar or pea screeds are still needed if applied to wood flooring finishes. The production process is complex and the raw material waste is serious.

The extruded sheet aluminum foil-coated module not only has the functions of heat preservation and heat insulation, but also has the function of heat reflection, and is more suitable for wood floor type veneer floor heating. However, for floor tile type facing floor heating, the construction process is complex, and the aluminum foil surface is difficult to bond with the tile adhesive and often needs interface treatment. Meanwhile, in the use process of floor heating, internal expansion force can be caused inside the floor heating system due to the alternation of cold and hot circulation, and due to poor interface bonding force after the prior treatment, the phenomenon of hollowing can still occur, so that the ground is hollowed and cracked, and even the ground is vibrated. The embedding groove of the existing floor heating pipe is generally in a U-shaped groove structure, for example, in the existing patent CN 108204094A, the embedding groove without the closed opening is very easy to have hollowing and cracking phenomena after the floor heating pipe is subjected to internal expansion force, and the stability of a floor heating system is relatively poor. Once the ground heating coil cracks, the maintenance cost is high, and meanwhile, great inconvenience is brought to the life of residents.

The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited by the drawings and the specific embodiments.

Fig. 1 is an exploded view of a module plate according to a preferred embodiment of the present invention. As can be seen from fig. 1, the module board 1 is composed of a heat-insulating heat-reflecting coating layer 2 and a substrate 4. Wherein, a self-locking embedding groove 3 is arranged on the substrate 4. The shape of the heat-preservation heat-insulation reflecting coating 2 is matched with the upper surface of the substrate 4.

Fig. 2 is an enlarged schematic view of a self-locking insert groove according to a preferred embodiment of the present invention. As can be seen from fig. 2, the cross-sectional structure of the self-locking mosaic groove 3 is not a conventional U-shaped structure. The bottom of the self-locking inlay groove 3 is a semicircular arc bottom 31, the upper parts of both ends of the arc bottom 31 are parallel side parts 32 of a parallel plane structure, and the parallel side parts 32 are connected with a convergent part 33 through arc connecting parts 34. Wherein the converging portion 33 has two parallel oppositely arranged side surfaces with a width of 3 mm. The distance between the two side surfaces is shorter than the outer diameter of the water heating pipe accommodating phi 20 in the embodiment by 2 mm. Therefore, the water heating pipe can be smoothly installed in the installation process, and enough constraint force can be ensured when the water heating pipe expands outwards due to internal expansion force. Meanwhile, the depth of the self-locking insert groove 3 is greater than the outer diameter of the received water heating pipe by 1mm (fig. 3). Therefore, a certain space is provided for the expansion of the water heating pipe, and the water heating pipe is favorable for releasing part of internal tension through smile expansion of the water heating pipe.

Fig. 3 is a schematic view of a module board according to a preferred embodiment of the present invention. As can be seen from fig. 3, in the using process, the heat-insulating reflective coating 2 is sprayed on the upper surface of the high-strength extrusion molding substrate 4 and the inner surface of the self-locking mosaic groove 3 by a machine, and the water heating pipe 5 is inlaid into the self-locking mosaic groove 3. The distance between the opposite side surfaces of the convergence part 33 of the self-locking embedding groove 3 is smaller than the outer diameter of the water heating pipe, and the depth is larger than the outer diameter of the water heating pipe.

The coating formed by the coating adopted in the embodiment has the reflection capacity not lower than the heat reflection capacity of the aluminum foil, but the processing technology is far simpler than the technology of coating the aluminum foil, and the production and the manufacture are easier. Meanwhile, the coating can be firmly bonded with a high-strength extruded sheet to form a whole, and can also be firmly bonded with a ceramic tile adhesive. The floor heating system has the advantages that the heat insulation effect of heat reflection (radiation) can be achieved, the bonding effect of the upper part and the lower part is achieved, the floor heating system and the ground finish coat form a whole in the using process, the overall stability is greatly improved, and the probability of occurrence of the problems of hollowing and cracking of the ground caused by the water heating pipe is reduced.
