Description

Ground heating structure

Technical Field

The application relates to the field of floor heating.

Background

The Floor Heating is short for Floor radiation Heating, and is called radiation Floor Heating, the whole Floor is uniformly heated by using a heat medium in a Floor radiation layer as a radiator, and heat is supplied to the indoor space by using the Floor in a radiation and convection heat transfer mode, so that the purpose of comfortable Heating is achieved. The heat transfer medium is divided into water ground heating and electric ground heating according to different heat transfer media.

The water floor heating is a heating mode which heats water to a certain temperature, conveys the water to a water pipe heat dissipation network under the floor and realizes the heating purpose by heating the floor.

The electric floor heater is a semi-transparent polyester film which can generate heat after being electrified and is made by processing and hot-pressing conductive special printing ink and metal current carrying strips between insulating polyester films. When the heating device works, the carbon-based ink is used as a heating body, and heat is sent into a space in a radiation mode, so that a human body is warmed.

However, the traditional water floor heating system and the traditional electric floor heating system have the problems of slow heat transfer rate and long startup waiting time. Wherein the temperature of water underfloor heating system need keep 50 ~ 60 ℃ just can let the user experience warmly, but heat low-temperature water to 50 ~ 60 ℃ in cold weather and need consume a large amount of energy, and the heat loss rate of 50 ~ 60 ℃ high-temperature water is high in cold day moreover, leads to underfloor heating system's energy consumption to further increase. In addition, the water temperature in the ground heating pipe is kept at 50-60 ℃ for a long time, and scales are easy to form. The traditional electric floor heating system has the problems of low heat transfer rate and high energy consumption due to structural defects.

The floor heating system can be divided into a dry floor heating system and a wet floor heating system according to different paving structures.

The dry floor heating is also named as ultra-thin floor heating, because the installation mode of the dry floor heating does not need floor heating backfill compared with the installation mode of common floor heating, the dry floor heating is also named as dry floor heating, and because a backfill layer is not needed, the occupied layer height is reduced compared with the common floor heating, and the ultra-thin floor heating is also named as ultra-thin floor heating.

However, the conventional dry floor heating has a higher manufacturing cost than the wet floor heating, and cannot be installed under floor finishing materials such as floor tiles, marble, etc., because these materials must be fixed using cement when being laid. The dry floor heating is not provided with a pea stone backfill layer, the floor heating coil is easy to damage, the service life of the floor heating is reduced to a certain extent, and even later maintenance problems such as water leakage and the like are easy to occur.

The wet floor heating is the mature installation process of the water heating floor heating, and is widely applied to the electric heating floor heating. The wet floor heating is relatively low in price and is the leading technology of the domestic floor heating market. The wet type is to embed the floor heating pipeline with concrete and then lay ground materials such as ground, ceramic tiles and the like on the concrete layer. The layer of concrete not only plays a role in protecting and fixing the water heating pipeline, but also is a main channel for transferring heat. The concrete layer can enable heat to be uniformly distributed, and the condition of local overheating or overcooling is reduced.

However, in wet floor heating, sand and stone mixed soil layers must be poured, so that the average weight is heavy, and the bearing capacity of the wet floor heating is about 8 times that of a radiator mode. In the wet floor heating, heat preservation is firstly paved on a cement surface, then pipes are arranged, then cobble cement is used for pouring and leveling, and a ground decoration layer is added, so that the height is generally 8 centimeters. In addition, the construction cycle of wet-type ground heating is long, and the requirement for constructor's specialty is high, in case bury in the water pipe or the electric heat membrane of subsurface emergence damage, must demolish concrete filling layer, and is very complicated.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings of the embodiments of the present application. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the application without any inventive step, are within the scope of protection of the application.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application belongs. The use of the terms "a" or "an" and the like in the description and in the claims of the present application do not denote a limitation of quantity, but rather denote the presence of at least one.

In the description of the present specification and claims, the terms "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present application and simplifying the description, but do not indicate or imply that the referred device or unit must have a specific direction, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

Embodiments of the present application will now be described with reference to the accompanying drawings.

The first embodiment is as follows:

fig. 1 to 4 show a preferred embodiment of the floor heating structure of the present application, which includes a floor heating pipe 1 for supplying hot water and a plurality of floor boards 2 positioned above the floor heating pipe.

The key improvement of this embodiment is that each floor board 2 is composed of a metal corrugated board 201, a face board 202 attached and fixed on the upper surface of the metal corrugated board, and a floor buckle 203 fixedly connected to the side edge of the metal corrugated board. The metal corrugated board 201 is laid above the floor heating pipe 1 and is connected with the floor heating pipe 1 in a heat conduction mode, and the floor blocks 2 are connected through floor buckles 203 buckled with each other.

It can be seen that each floor block 2 of the floor heating structure is directly paved above the floor heating pipe 1, and each floor block 2 is connected with each other into a whole by means of the floor buckles 203 of the floor blocks 2, the construction method of pouring sand, stone and concrete is not needed, the all-dry construction is adopted, the installation efficiency is high, and the floor blocks can be easily dismantled for reuse. And, the corrugated sheet heat conduction rate of metal material is high, can lead the panel 202 with the heat of below ground heating coil 1 fast, gives off to indoor by panel 202 again, promotes indoor temperature fast.

The (upper surface of the) panel 202 is exposed to the environment for people to step on. The face sheet 202 is typically a marble, tile, wood or plastic sheet, including relatively soft rubber or plastic sheets. The panel 202 is a wooden board in this embodiment, and the thickness of the wooden board is only a few millimeters.

The panel can also be a wear-resistant coating coated on the upper surface of the metal corrugated board, the wear-resistant coating has a certain thickness and is in a fixed state, and the wear-resistant coating is in a plate shape in appearance and is also an optional panel structure.

The metal corrugated sheet 201 of the present embodiment also includes, as with the conventional corrugated sheet: an upper plate body 201a, a lower plate body 201b arranged in parallel below the upper plate body, and a corrugated medium layer 201c fixedly connected between the upper plate body and the lower plate body.

Further, the upper plate 201a is adhesively fixed to the upper surface of the corrugated core layer 201c by an adhesive (hot melt adhesive film), and the lower plate 201b is adhesively fixed to the lower surface of the corrugated core layer 201c by an adhesive (hot melt adhesive film). Of course, the upper and lower plate bodies and the corrugated medium layer may be welded and fixed.

The panel 202 is adhesively fixed to the upper surface of the upper plate body 201a by an adhesive, thereby achieving the bonding of the panel 202 to the metal corrugated board. In order to improve the compression and impact resistance of the panel 202 in the vertical direction and prevent the panel 202 from being broken when it is subjected to a vertical load or a vertical impact (especially, when the panel is a marble plate or a tile plate), the adhesive for bonding the panel 202 and the upper plate 201a is preferably continuous and dense, so that a continuous and dense adhesive layer (not shown) is formed between the panel 202 and the upper plate 201 a.

The "continuous and dense adhesive layer" can be realized by increasing the amount of the adhesive, or by sandwiching a hot-melt adhesive film between the panel 202 and the upper plate 201a, and melting the hot-melt adhesive film at a high temperature and then solidifying the molten hot-melt adhesive film at a low temperature.

Different from the conventional corrugated board, the area of the corrugated core layer 201c in the metal corrugated board of the embodiment is smaller than the areas of the upper board body 201a and the lower board body 201b, and each side edge of the corrugated core layer 201c is located inside the corresponding side edge of the upper board body 201a and the lower board body 201b, so that a floor buckle embedding gap 201d located around the corrugated core layer 201c is formed between the upper board body 201a and the lower board body 201 b. The floor fastener 203 is fitted into the floor fastener fitting gap 201d, and a floor fastener portion fitted into the floor fastener fitting gap 201d is welded and fixed to the upper plate 201a and the lower plate 201 b.

The floor buckle 203 may be welded to only one of the upper plate 201a and the lower plate 201 b. The advantage of so designing lies in: the assembly efficiency of the floor buckle and the metal corrugated plate is improved. But has the defects that: the connection strength of the floor buckle and the metal corrugated sheet is slightly poor.

Alternatively, an adhesive may be applied to the floor buckle 203, and the floor buckle portion fitted into the floor buckle fitting gap 201d may be fixed to the upper plate 201a or/and the lower plate 201b by the adhesive.

In this embodiment, the metal corrugated board is a corrugated aluminum board, the upper board body 201a and the lower board body 201b are both aluminum boards, and the middle corrugated core layer 201c is an aluminum corrugation.

The upper board body 201a, the lower board body 201b and the corrugated core layer 201c in the metal corrugated board are made of other materials, such as: the upper plate 201a and the lower plate 201b may be steel plates, and the middle corrugated layer 201c may be stainless steel corrugations.

In this embodiment, the corrugated substrate is a rectangular plate having a long strip shape and the shape of the corrugated substrate is matched with that of the floor block. Like most corrugated board, the corrugated core layer 201c in this embodiment is also a wave-shaped structure having a plurality of alternately arranged peaks and valleys. It is known that the bending strength of the rectangular strip board in the length direction is weaker than that in the width direction, while the bending strength of the corrugated medium layer in the direction perpendicular to the arrangement of the peaks and valleys is much higher than that in the direction parallel to the arrangement of the peaks and valleys. Based on this, this embodiment arranges each crest and the trough of this wavy flute core layer along the width direction of flute base plate in turn to rectangular floor block's bending resistance in length direction has been promoted greatly.

As described above, the upper plate 201a is adhesively fixed to the upper surface of the corrugated core layer 201c by an adhesive (hot melt adhesive film), and the lower plate 201b is adhesively fixed to the lower surface of the corrugated core layer 201c by an adhesive (hot melt adhesive film). Therefore, the bonding process is controlled only when the upper plate body and the lower plate body are bonded with the middle corrugated core layer, all wave crests of the corrugated core layer can be bonded and fixed with the upper plate body 201a, and all wave troughs are bonded and fixed with the lower plate body 201b, so that all wave crests and all wave troughs of the corrugated core layer are tightly combined with the upper plate body and the lower plate body, and the bending strength of the rectangular floor block is further improved.

In some other embodiments of the present application, each of the wave crests and each of the wave troughs of the corrugated medium layer may be provided as a planar structure, and (the upper surface of) each of the planar structures is arranged to abut against and is adhesively secured to (the lower surface of) the upper plate body, and (the lower surface of) each of the wave troughs of the planar structures is arranged to abut against and is adhesively secured to (the upper surface of) the lower plate body. Therefore, the bonding area and the bonding strength of the corrugated medium layer, the upper plate body and the lower plate body can be greatly increased, and the upper plate body or the lower plate body is prevented from being peeled off from the corrugated medium layer in the using process.

If the floor heating pipe 1 is directly laid on the ground 6 (generally, indoor ground including floor surface) and directly contacts with the ground 6, a large part of the heat of the hot water in the floor heating pipe 1 is transferred to the ground 6 and lost, based on this, the present embodiment further lays a layer of heat insulation pad 3 on the ground 6, the floor heating pipe 1 is laid on the heat insulation pad 3, the heat transfer path of the floor heating pipe 1 downward is isolated by the heat insulation pad 3, and it is ensured that most of the heat is transferred upward to the floor block 2.

The heat insulation pad 3 is preferably made of foam plastic having a certain flexibility so as to have a protection performance on the floor heating pipe 1, and the foam plastic is light and environment-friendly and has an excellent sound insulation performance.

Further, the heat insulating mat 3 is made of a polystyrene resin (also a foamed plastic) having a fire-proof property.

If the floor heating pipe 1 is directly arranged on the upper surface of the flat heat insulation cushion, the floor heating pipe 1 is easy to shift and unstable in position, and is easy to deform and flatten under the vertical pressure of an upper floor block. In this respect, in the present embodiment, a plurality of pipe grooves 301 are formed on the upper surface of the heat insulating mat 3, and the floor heating pipes 1 are inserted into the pipe grooves 301.

If the ground heating coil 1 and the metal corrugated sheet 201 direct contact, the two are linear contact, and heat conduction area is little, thereby the easy bending deformation of the ground heating coil 1 of plastics material leads to its and top floor block contact failure moreover, and heat transfer efficiency can't be ensured. Based on this, a plurality of heat conduction pipe clamps 4 of joint on ground heating coil 1 of this embodiment, heat conduction pipe clamp 4 has the heat conduction top surface, and this heat conduction top surface is in tube seat 301 notch position moreover, and the vertical butt of lower surface of plate body 201b under the heat conduction top surface of heat conduction pipe clamp 4 and the metal corrugated sheet. The floor heating pipe 1 and the floor block 2 are indirectly connected in a heat conduction way by the heat conduction pipe clamp 4.

Further, in this embodiment, a glue groove 401 recessed downward is formed on the heat conducting top surface of the heat conducting pipe clamp 4, and a heat conducting glue 5 for bonding the lower plate body 201b and the heat conducting pipe clamp 4 is disposed in the glue groove 401, so as to further ensure good heat conduction between the heat conducting pipe clamp 7 and the metal corrugated plate 201.

In order to allow the adjacent floor boards to be easily connected by means of the floor buttons 203 thereon, the present embodiment is provided with one floor button 203 on each side of the rectangular metal corrugated board 201, so that each floor board is provided with four floor buttons 203. And, two of the floor buckles 203 are male buckles 203a, and the other two floor buckles 203 are female buckles 203b, as shown in fig. 3. When assembling, the male button 203a and the female button 203b of two adjacent floor boards are buckled and connected, as shown in fig. 5.

It should be noted that the two male buckles 203a and the two female buckles 203b on the floor board can be different structures. For example, the floor board disclosed in chinese patent application with publication number CN101910528B, wherein the two long sides are respectively provided with a male buckle and a female buckle which are mutually matched in an angle-tilting manner, and the two short sides are respectively provided with a male buckle and a female buckle which are mutually matched in a vertical displacement manner and have another structure, is obviously not excluded in the claims of the present application.

Example two:

fig. 6 shows a second preferred embodiment of the floor heating structure of the present application, which is substantially the same as the first embodiment except that: the length of the heat conducting pipe clamp 4 in the embodiment is basically equal to that of the ground heating pipe 1.

Example three:

fig. 7 shows a third preferred embodiment of the floor heating system of the present application, which has substantially the same structure as the first embodiment except that: in this embodiment, a heat conducting pipe clamp is not provided, but a layer of heat conducting film 7 is coated on the upper surface of the heat insulating pad 3, a part of the heat conducting film 7 is sandwiched between the outer pipe wall of the ground heating pipe 1 and the groove wall of the pipe groove 301, and the metal corrugated board 201 (specifically, the lower plate body 201b) is arranged on the upper surface of the heat conducting film 7 in an abutting manner. In this way, the heat conduction film 7 has a large contact area with the floor heating pipe 1 and the metal honeycomb panel 201, so that heat of the floor heating pipe 1 can be quickly transferred to the metal honeycomb panel 201.

The heat conductive film 7 is preferably an aluminum foil.

The above are exemplary embodiments of the present application only, and are not intended to limit the scope of the present application, which is defined by the appended claims.
