Description

  The present invention relates to a flat heat generating block and a method for manufacturing the flat heat generating block. More specifically, the present invention has a simple structure, yet has excellent snow melting effect, weather resistance, good workability, and low freezing point. Can be stably heated and heated, and is inexpensive and economical. Especially, in the snowy country, the government, local public organizations, etc. The present invention relates to a snow melting and heat insulation panel that can be easily used in areas other than roads in public parks and a method for manufacturing the same.

In areas where there is a lot of snow, the snow on the roads and passages should be removed as appropriate during the snowfall period in winter to ensure transportation, maintain the living environment, and provide emergency patients and transport. It is necessary to revitalize important social infrastructure. For this purpose, the administrative agencies in each district form a considerable budget and perform snow removal work as necessary during the snowfall period. ing.
However, such snow removal work uses a large-scale snow removal device and requires the labor of many workers. In addition, depending on the region, it is necessary to carry out the snow removal operation as a result. The costs associated with this increase, which is a problem for the administrative agencies in each district in that the economic burden is increasing.
As one method for solving such a problem, it has been studied to simplify or eliminate the snow removal processing operation so that the snow does not accumulate on the road or the bridge even if it snows.

As one specific example, for example, groundwater or hot spring water pumped up by burying pipes on the ground, or on roads or bridges where snow is heated, or primary accumulation of snow removed By discharging water to the location, the snow that had accumulated snow was actively melted, thereby revealing the snow removal effect and preventing the road surface from freezing. The use of groundwater is restricted.
Therefore, a method of preventing snow melting on the road surface and freezing on the road surface by spraying agents such as anti-freezing agents containing calcium chloride and carbon powder on the above-mentioned places, or heating pipes embedded in the ground A method of preventing snow melting on the road surface and freezing on the road surface by heating by circulating an antifreeze liquid or by heating a heating wire embedded in the ground It has been.

For example, a mouth heating device that embeds a pipe or a heating wire in the ground is disclosed in JP-A-11-336038.
(Patent Document 1) and the like.
However, the mouth heating device that embeds pipes and heating wires on the ground is not only expensive for burial work, but trucks loaded with luggage and vehicles traveling at high speed are always on the road. Therefore, pipes and heating wires buried due to repeated load and vibration on the road surface are damaged or disconnected, and maintenance costs tend to increase. Is unsuitable.
On the other hand, as described above, a method of spraying a medicine that accelerates snow melting has been widely used. However, the medicine sprayed on the road can be used to reach private houses and fields around the road. Scattering has become a major social problem as a cause of new pollution.

  However, the above-mentioned problems are particularly problems seen from the administrative side managing public roads and bridges, and it goes without saying that such problems need to be improved immediately. As a matter of concern, in recent years, the above-mentioned administrative side has ensured the life and safety of local residents by maintaining and maintaining social life, public transportation and other necessary environments as an original obligation. For this purpose, it is not a problem of the area where snow removal processing operations are performed on predetermined roads and bridges, etc., and the area concerned is not involved in the administration, such as around private houses, inns, hotels, restaurants, private medical care, nursing care facilities, etc. During the snowfall season in winter, it is necessary for those owners to perform the snow removal work at their own expense.

Also, even if the sidewalks and passages in public parks are within the administrative scope, they are often postponed due to labor shortages or budget shortages, leaving the inconvenience and danger of those who use them for a long time. The state that is being done frequently occurs.
For example, in a private house or a building where an unspecified number of people gather, the approach path and under the eaves from the main road to the entrance and entrance of the building, the parking lot and the entrance to the entrance of the building and the entrance, the entrance to the entrance, etc. Although it is desirable to always maintain zero snow cover, it is still necessary due to lack of manpower, lack of budget, and aging of local residents. It is extremely difficult to maintain the condition of zero snow.

On the other hand, the snow removal device or various devices or devices for reducing snow accumulation have been widely used in the past, but they are expensive in cost and unsuitable for personal use. Because it is large and heavy, it is difficult to use as an individual. Actually, individual individuals use snow scoops to perform snow removal work, especially for elderly people. It goes without saying that it is work.

Against this background, a lightweight and compact snow-melting plate that incorporates a heating element that generates heat when energized is proposed.
For example, a snow melting mat in which a sheet-like heating element that generates heat when energized with electricity or a heat-dissipating pipe that circulates hot water is covered with an appropriate concrete material or synthetic resin film material is disclosed in, for example, Japanese Patent Application Laid-Open No. 2004-316377. As disclosed in Japanese Laid-Open Patent Publication (Patent Document 2) or Japanese Patent Laid-Open No. 2010-24893 (Patent Document 3), concrete or resin as a pavement material is used to prevent human body damage accidents due to slip during snow melting. The structure of a snow melting / warming panel in which a heating element as described above is arranged or built in the surface substrate layer that is made porous by imparting water permeability or in the lower part thereof is disclosed in, for example, Japanese Patent Application Laid-Open No. 2007-270526. (Patent Document 4), JP-A-7-166508 (Patent Document 5), JP-A-8-326209 (Patent Document 6) or JP-A-8-1. 4755 JP disclosed in (Patent Document 7), and the like.

However, these snow-melting mats and snow-melting / heat-retaining heating elements are mainly made for the purpose of use on the roof, so the surface is fragile, and considerable weight is frequently and repeatedly applied. It is clear that it is the right direction, and since it is heavy and is still unsuitable for personal use and construction, it has never been put to practical use until now.

Furthermore, in the above-mentioned known technology, even if the concrete, rubber, or synthetic resin layer is made porous to impart water permeability, the many holes are closed in a short period of time. The water permeability of this product was in a state where it could not be expected at all.
In addition, the snow melting panel and the snow melting sheet according to the above-described prior art have a flat surface, and as a result, even when a pedestrian is melting snow, a part of water or snow remains. There is also a drawback that it is slippery and has a very high risk of damage to the human body.

Japanese Patent Laid-Open No. 11-336038 JP 2004-316377 A JP 2010-24669 A JP 2007-270526 A JP 7-166508 A JP-A-8-326209 JP 2008-184755 A

Therefore, the object of the present invention is to improve the above-mentioned problems of the prior art, have a simple configuration, facilitate installation work, and reduce the cost of the snow melting system itself and the installation cost. Even when heavy objects are repeatedly pressed, they can maintain durability and withstand long-term use, and at the same time improve heat resistance and weather resistance to enable fixed installation throughout the year. The basic structure is a unit that is blocked so as to have portable dimensions and weight, and it is easy and simple for individuals to design and install snowfall facilities and to maintain and repair them. The cost required for management is low, the maintenance cost and energy consumption are also reduced, and it can be installed continuously throughout the year. The present invention provides a snow melting heat generating panel that can be used, and further has high water permeability and water permeability, greatly reduces the amount of water remaining on the panel surface, and It is an object of the present invention to provide a heat-generating block for snow melting and heat insulation that prevents pedestrians from slipping by completely and effectively preventing snow from freezing.
Another object of the present invention is not only to use for melting snow, but also to maintain the surface temperature of the ground such as roads, fields or farms for livestock, etc., or to rear livestock. It is an object of the present invention to provide a heat-retaining heat-generating panel that can be used as a heat-retaining heat-generating panel for keeping the room temperature in a room or greenhouse or a greenhouse in a constant condition.

  Hereinafter, the configuration of each specific example will be described in detail with reference to the drawings for each of the snow melting / warming heat generating panel and the method for manufacturing the snow melting / warming heat generating panel according to the present invention.

  That is, FIG. 1 and FIG. 2 show the configuration of one specific example of the snow melting / warming heat generating panel 100 which is the first specific mode according to the present invention. And a snow-melting / heat-retaining heat generating block 100 comprising a flat plate-shaped substrate part 1 having a three-dimensional rectangular shape having a width w and a height h. Porous structure in which a plurality of pores 4 having water permeability are formed by intermittently joining a plurality of particles 2 to each other via a bonding agent 3 interposed between the particles 2 And a lattice made of a metal material arranged in a direction substantially parallel to the planar portion 20 along the longitudinal direction of the substrate portion 1 inside the substrate portion 1.

At least one lead wire 12 electrically connected to the body 8 is provided so as to protrude, and the free end portion 13 of the lead wire 12 is watertight and detachable from a predetermined power supply line. Features a connector part 14 that can be joined Snow melting, thermal insulation for heat block 1, is shown.

  The snow melting / warming heat generating panel 100 according to the present invention is made of concrete, rubber, or synthetic resin, which is conventionally used for snow melting / warming heat generating panels or snow melting / warming heat generating blocks. The membrane layer material, or the material composed of a porous structure in which appropriate granular materials are mixed into the material from the outside to make it porous, still has a large weight, insufficient strength, and water permeability. However, in the present invention, the conventional material consciousness has been fundamentally changed. In addition, a material that can surely exhibit porosity if it is molded is selected in advance, and a granular material made of a hard material capable of forming the porosity is selected as a starting material, and a predetermined time elapses in the granular material. It is obtained by employing a novel technical concept called used reliably coagulated natural drying conditions comprising air drying conditions, those mix with fluid-like bonding material which can secured as a base of the heating panel by a.

  That is, in the heat melting block for snow melting and heat insulation according to the present invention, as shown in FIG. 3, a granular material composed of a plurality of hard materials and a fluid that can be solidified and fixed reliably under natural drying conditions. The fluid-like molding material 115 is mixed, and the fluid-like molding material is injected and filled into an appropriate mold 110 as will be described later. By leaving it for a desired time and allowing it to dry naturally, including air drying, a plurality of the granular materials 2 made of a hard material are mainly used, and the granular material 2 is interposed between the granular materials 2. As a result, a large number of holes 4 for establishing water permeability are formed between the granular bodies 2, thereby forming a strong and porous structure. A substrate material having the quality structure 5 is constituted.

  Accordingly, the substrate portion according to the present invention has sufficient strength because the interconnected hole portion and the communication tubular space that allow a large amount of water to permeate and permeate inside the substrate material are formed. A substrate portion that is excellent in water permeability and capable of reducing the weight is formed.

By the way, although it does not specifically limit as the granule 2 which consists of the said hard material in this invention, For example, the said granule 2 has gravel and a pebble whose average particle diameter is 3 mm thru | or 15 mm. It is desirable that it is composed of one or more selected from rock fragments, lava stone fragments, concrete fragments, ceramic fragments and the like.
As the granular material 2 in the present invention, it is desirable to use gravel generally called gravel.

Further, in the present invention, it is also desirable that the granular material 2 further includes a granular material 2 having a heat radiation effect function or a granular material 2 having a function of emitting far infrared rays. .
For example, it is a preferable specific example that the granule 2 includes the granule 2 having a function of emitting far infrared rays and made of carbon, ceramics, tourmaline, volcanic rock, or granite.

On the other hand, the bonding agent 3 used in combination with the granular material 2 in the present invention is not particularly limited. For example, the bonding agent 3 mainly includes an epoxy-based synthetic resin component. It is possible to use a bonding agent or a two-component bonding agent 3.
That is, the bonding agent 3 in the present invention can be easily and uniformly mixed with the granular material 2 to form a liquid slurry, and thus formed between the plurality of granular materials 2. Adhesives that can easily penetrate into adjacent areas including the parts that are in contact with each other and that can be completely solidified within a short time, for example, 6 hours, without taking too much time are used. It is desirable.
This is because when the present invention manufactures the snow melting / warming heat generating block 100, the material cost and the energy cost in the production process are greatly reduced, and the cost and the reduction for making it possible for individual purchase and use are also reduced. In order to realize this, the main purpose of the bonding agent is to completely solidify and form a substrate with high strength without going through a separate heat treatment step.

  Of course, the solidification time based on the natural drying conditions of the bonding agent 3 can be adjusted by adding an appropriate coagulant to the bonding agent 3, but the natural drying conditions of the bonding agent 3 can be adjusted. If the solidification time based on this is set too long, the bonding agent 3 is interposed between the granules 2 during the solidification process in the mold and during the solidification process of the substrate part 1 taken out from the mold. As a result, the arrangement density of the bonding agent in the substrate portion is uneven, and a large amount of the bonding agent 3 is collected on the bottom surface of the substrate portion 1. A film-like film is formed, and the effect of water permeability or water permeability is hindered.

Therefore, the bonding agent 3 is dispersed and arranged in a substantially uniform state in the granular material 2, and the resin adhesive layer 6 formed between the contact portions of the adjacent gravel particles 2 is also uniformly distributed and arranged. For this purpose, the solidification time of the bonding agent 3 is preferably as short as possible, and 6 hours is one standard.
In order to achieve such an object, it is desirable to use the bonding agent 3 made of an epoxy-based synthetic resin as having a function of solidifying in a short time by the natural drying.

In the present invention, the granular material 2 and the bonding agent 3 are mixed at an appropriate mixing ratio of, for example, 1: 1 to 3: 1 according to the purpose of use. The slurry is subjected to a stirring operation for a predetermined period of time to form a slurry-like molded body material in which the granular material 2 and the bonding agent 3 are uniformly mixed, and then the molding material is appropriately molded as described later. It is poured and filled in, and solidification processing is performed by natural drying for a predetermined time, thereby forming the snow melting / warming heat generating block 100 having a desired shape.
As shown in FIG. 4, in the substrate portion of the snow melting / warming heat generating block 100 formed according to the present invention, the bonding agent is uniformly permeated between the gravel particles 2, and the adjacent gravel particles 2 are adjacent to each other. Since the resin adhesive layer 6 solidified by the bonding agent 3 is formed at the abutting portions, the substrate portion as a whole, although a large number of space portions 4 exist in the inside, is conventionally known. Although the weight of the concrete block is greatly reduced, it is possible to show substantially the same strength as that of the conventional concrete block.

Further, in the snow melting / warming heat generating block 100 according to the present invention, rain water or other water adhering to the surface of the block 100 or water formed by melting snow is porous to the substrate portion 1. Using the function, the inside of the board part is sequentially moved downward, and drained from the bottom surface of the board part through the ground or through an appropriate drainage passage connected to the snow melting / warming heat generating block 100. become.
Since the surface of the heat-generating block 100 for melting and keeping heat according to the present invention is always kept dry as described above, the water does not freeze at all, and the fine irregularities formed by the granular material 2 are Since it is formed on the surface, the slip prevention effect is remarkably excellent.
Further, in the present invention, since the granular material 2 is used, even when the snow melting / warming heat generating block 100 is used for a long period of time, the space portion in the substrate portion 1 does not contain earth or sand or dust. It is possible to manufacture a heat-generating block for snow melting and heat insulation that is not clogged with eaves and can exhibit high-performance water permeability for a long period of time.

The shape and size of the snow melting / warming heat generating block 100 according to the present invention are not particularly limited, but can be carried by an individual by his own construction work, and the enforcement work is simplified. However, if it is considered on the premise that the cost is low, the length s of the substrate portion 1 in the longitudinal direction in the snow melting / warming heat generating block 100 is set to, for example, 800 mm or 1600 mm. On the other hand, the length w of the width is preferably set to 400 mm to 600 mm, for example, and the height h is preferably set to a dimension of 25 mm to 50 mm, for example.
On the other hand, in order to achieve the above-described object, the total weight of the snow melting / warming heat generating block 100 in the present invention is preferably set between 25 kg and 70 kg, for example.

Next, in the snow melting / warming heat generating block 100 according to the present invention, the substrate portion 1 is arranged in a direction substantially parallel to the plane portion 20 along the longitudinal direction of the substrate portion 1. For example, a support plate portion 7 having a lattice shape or a mesh shape made of a metal material such as stainless steel is provided.
When it is necessary to reduce the thickness of the heat-generating block 100 for melting and keeping heat in the present invention, the thickness or the amount of use of the members constituting the support plate portion 7 is slightly reduced. It is desirable to design with multiple eyes.

  As will be described later, the support plate portion 7 in the present invention holds and fixes the linear heating element portion 8 used in the present invention inside the substrate portion 1, and the molding material described above. In addition to having the function of holding and fixing the linear heating element portion 8 so that the linear heating element portion 8 does not move or displace when the resin is injected into the mold and filled, the strength of the entire substrate portion 1 And the function of maintaining a predetermined strength is achieved. Furthermore, since the support plate portion 7 is joined to the linear heating element portion 8, the support plate portion 7 is The heat energy emitted from the linear heating element portion 8 is effectively diffused into the substrate portion 1 and the heat generation effect and the heat radiation effect of the snow melting / warming heat generation block 100 are improved. is there.

That is, as shown in FIGS. 4A to 4C, the support plate portion 7 is a member having a surface 21 substantially parallel to the flat portion 20 formed by the upper surface of the substrate portion 1. A grid-like reinforcing bar 71 formed of an appropriate metal material and a weft-direction reinforcing bar 72 arranged in a direction substantially orthogonal to the arrangement direction of the vertical reinforcing bars 71 intersect each other. It may be a plate-like member, or a net-like or mesh-like flat plate-like member made of an appropriate metal material.
The support plate portion 7 used in the present invention is preferably made of a metal material having high strength and high thermal conductivity and / or heat dissipation.

Furthermore, in the present invention, the support plate portion 7 may be disposed in the vicinity of the bottom surface portion of the substrate portion 1 or may be predetermined upward from the bottom surface portion 9 of the substrate portion 1. It may be arranged at a site separated by a distance.
That is, FIG. 4 (A) which is a cross-sectional view seen from the longitudinal direction of the heat-generating block 100 for snow melting / warming according to the present invention and FIG. 4 (B) which is a cross-sectional view seen from the width direction. In one specific example, in the inside of the substrate portion 1 that is close to the bottom surface portion 9 side of the substrate portion 1 in the snow melting / warming heat generating block 100, parallel to the bottom surface of the bottom surface portion 9. The support plate portion 7 is disposed.

As an improvement technique of the above specific example, as shown in FIG. 4C, the support plate portion 7 moves upward along the height direction h of the substrate portion 1, and the substrate portion 1. It may be configured such that the support plate portion 7 is arranged at a substantially central portion in the height direction.
In the above specific example, the longitudinal reinforcing bar 71 and the weft reinforcing bar 72 are appropriately connected at the portion where both intersect, for example, a wire, a joining jig, an adhesive. It is desirable that they are joined using a joining and fixing technique such as welding.

  Alternatively, in the snow melting / warming heat generating block 100 according to the present invention, when it is necessary to provide a grounding function to the snow melting / warming heat generating block 100 itself, another specific example according to the present invention. As shown in other specific examples of the present invention shown in FIGS. 5A to 5C, at least a part of the support plate part 7 of the substrate part 1 is partly supported. The plate portion 7 is joined and fixed, and one end portion of the plate portion 7 extends perpendicularly to the direction from the lower surface portion of the support plate portion 7 toward the bottom surface portion 9 of the substrate portion 1 or through an appropriate angle. A band-like or linear body 24 made of a metal material and having conductivity is attached, whereby at least a part of the free end 25 of the band-like or linear body 24 is formed on the bottom surface portion 9 of the substrate portion 1. Even if it is configured to be exposed to a flat surface There.

That is, in one specific example of the present invention, at least a part of the bottom surface part 9 of the substrate part 1 is associated with a part of the support plate part 7 and the belt-like or linear body 24. Is exposed to form a ground terminal portion.
One characteristic technical configuration in the configuration of the specific example of the snow melting / warming heat generating block 100 according to the present invention described above is that the support plate portion 7 is formed on a part of the support plate portion 7. The metal plate is disposed in a direction orthogonal to the plane 21 and is bonded and fixed to the metal material constituting the support plate portion 7 through an appropriate means, and further from both the upper and lower surfaces of the plane 21 formed by the support plate portion 7. A metal auxiliary member 24 that is extended and arranged is provided, and a portion of the metal auxiliary member 24 that exists on the upper surface of the support plate 7 is a linear or belt-like long heating element. The portion 8 functions as a joining means for joining the support plate portion 7, and the tip 25 of the portion existing on the lower surface of the support plate portion 7 is exposed to the outside from the bottom portion 9 of the substrate portion 1. And this part functions as a grounding terminal. That is a heat-generating block 100 for snow melting, thermal insulation that is configured as.

  That is, in one specific example of the present invention, in the internal structure of the snow melting and heat retaining heat generating block 100, the substrate from the lower surface portion of the support plate portion 7 of the belt-like or linear body 24. By setting the length Y toward the bottom surface portion 9 of the portion 1 to an appropriate length, the support plate portion 7 is inside the substrate portion 1 in the height direction Z inside the substrate portion 1. The position is determined.

  The reason why the support plate portion 7 in the present invention has a lattice-like or mesh-like form is that, as described above, the substrate portion 1 which is a main constituent part in the present invention is a porous material having water permeability. The water generated by melting the snow accumulated on the snow melting and heat retaining heat generating block 100 is communicated with the other porous structure 5 of the substrate portion 1. It is required that the upper surface of the snow melting / warming heat generating block 100 is always kept in a dry state by flowing down to the snow melting / warming heat generating block 100 through the hole. Arranging a flat plate-like member that hinders the downward flow of the snowmelt water results in hindering the realization of the purpose. Therefore, in order to ensure the water permeability of the snowmelt water, the support plate portion 7 is provided. Lattice or mesh form Which is constituted by a member having.

  Next, in the snow melting / warming heat generating block 100 in the present invention, the snow melting / warming heat generating block 100 is formed on the support plate portion 7 arranged in the substrate portion 1. The support plate portion 7 is flat so that the substrate portion 1 can be energized at an appropriate temperature for an appropriate time to generate heat at an appropriate temperature and melt the snow accumulated during snowfall. Along the portion 21, a linear or belt-like long heating element portion 8 having an appropriate shape is arranged along an appropriate form.

  For the same reason as described above, the heating element 8 used in the present invention is required to ensure and maintain the water permeability of the snowmelt water, so that the concrete or rubber in the conventional heating member is used. Since the sheet-like heat generating plate generally used for the lower surface of the surface layer of the system cannot be used, a linear or belt-like long heating element 8, that is, a heating wire is used. .

  Further, the configuration of the linear or belt-like long heating element 8 used in the present invention is not particularly limited, but the long heating element is constituted by a hollow tube. Although it is possible to use a method in which warm water is circulated through the hollow tube and the block is heated, if such a warm water circulation system is employed, a water heater for boiling the warm water is required. Naturally, an energy supply source such as electricity and gas is necessary, and at the same time, a liquid circulation system for circulating the hot water in the hollow tube is necessary. Etc. is likely to occur frequently, so the maintenance cost must be enormous.

Therefore, in the present invention, basically, a system that generates heat using electric power is preferable, but the heat generating means using a conventionally known dichrome wire does not have a heat generating function in a cold region. Since it is sufficient, it cannot be used for the snow melting means. Therefore, in the present invention, as shown in FIG. The heat generating layer 53 mixed with the synthetic resin adhesive particles is disposed and covered with an appropriate insulating synthetic resin material layer 54, and the electrodes 51 and 52 are connected to a predetermined power source. It is desirable to use a heating element 8 in which the heating layer 53 generates heat when energized.
When the synthetic resin particles are designed so that the volume thereof changes according to the temperature, the heating element 8 described above changes the amount of electricity applied to the heat generating layer 53, so a line having a so-called self-temperature control function. It becomes possible to use it as a long or belt-like long heating element 8.

  However, as described above, the heat generating means 8 in the present invention needs to use a linear or belt-like long heating element as described above, and the shape thereof also has a circular cross section. Some have a linear body structure, others have a flat heating section and have a flat cross section, and any heating element can be used.

On the other hand, in the present invention, the linear or belt-like elongated heating element portion 8 is at least partly attached to at least part of the upper surface or the lower surface of the support plate portion 7 by an appropriate joining means, for example, , And are held and engaged using a wire, an appropriate fastener, or the like.
The number and arrangement of the linear heating element portions 8 in the present invention are not particularly limited. For example, as shown in FIG. 7 (A), on the upper surface or the lower surface of the support plate portion 7, Three linear heating elements 8 (8-1, 8-2, 8-3) in a straight line shape or a belt shape having a predetermined length are arranged in parallel with each other, and the longitudinal direction of the support plate 7 When arranged along the lines, the lead wires 12 led out from the respective elongated heating element portions 8 are connected to the snow melting / removal via appropriate connector portions 62-1, 62-2 and 62-3. A common internal power supply line 61 separately disposed in the heat-retaining heat generating block 100 is electrically connected at an appropriate portion, and one end of the common internal power supply line 61 is electrically connected to the external power supply line 64 appropriately. Since it is necessary to connect via the connector means 62-4, In the joint portion, bad connection, since failure or the like is much likely to occur, there are problems in maintenance cost in the future is high.

Therefore, in a preferred specific example of the present invention, as shown in FIG. 7B, a desired heating value can be obtained with a single linear or belt-like long heating element 8. The heat-generating member 8 having a necessary length is arranged in a zigzag shape, and the water-proof property having an appropriate shape provided at the tip of the appropriate lead wire 12 at the free end of the heat-generating member 8. It is desirable to be configured to be electrically connected to the external power supply line 64 via a connector having a watertight structure.

In the specific example according to the present invention, when the linear heating element portion 8 having a circular cross section is used, the arrangement form is not particularly limited. For example, the linear heating element portion having a flat cross section is used. 4 is used, as shown in FIGS. 4B and 4C, the longitudinal axis in the cross-sectional shape of the linear heating element portion 8 is set to the plane portion 21 of the support plate portion 7. The heating element portion 8 may be arranged on the flat surface portion 21 of the support plate portion 7 and arranged in a zigzag manner so as to be parallel to each other.

However, in such a specific example, in the portion where the heating element portion 8 is folded back at the left and right edge portions, the heating element portion 8 is turned up, so that at the time of molding When a problem occurs, there is a high possibility that the part will not be sufficiently bonded to the gravel component, resulting in insufficient strength.
Therefore, as a more preferable specific example in the present invention, as shown in FIGS. 5B and 5C, the longitudinal axis in the cross-sectional shape of the heating element portion 8 is the The support plate portion 7 is three-dimensionally arranged so as to be perpendicular to the flat portion 21 and arranged in a zigzag manner.

In the specific example of the present invention, the belt-like heating element portions 8 that are three-dimensionally arranged so as to be perpendicular to the flat surface portion 21 of the support plate portion 7 are arranged in a zigzag shape. Since both ends can be smoothly bent into a curved shape, the workability is good and the above-mentioned problems in quality are not present at all.

In the specific example of the present invention, when the belt-shaped heating element portion 8 having the flat shape is disposed on the upper surface of the support plate portion 7, the band-shaped heating element portion 8 is connected to the support plate portion. 7 is required to be engaged and fixed by using an appropriate engaging and fixing means. As one specific example, as shown in FIG. 5 (A) or FIG. 5 (B), In order to take the ground, the support plate portion 7 is bonded and fixed to each other at an appropriate portion, and one end portion thereof is directed from the lower surface portion of the support plate portion 7 toward the bottom surface portion 9 of the substrate portion 1. A conductive band-like or linear body 24 made of a metal material extending perpendicularly or through an appropriate angle is attached, but the band-like or linear body 24 is supported as it is. A strip-shaped wire that extends linearly toward the upper side of the upper surface portion 21 of the plate portion 7. Ku is formed on the linear body 26, is intended to keep the strip heating element 8 is fixedly arranged via an appropriate engaging fixing means spreadability of the linear member 24.

It is desirable that the belt-like body 24 and the belt-like body or the wire-like body 26 are integrally formed, and further, the wire-like body 26 integrated with the wire-like body 24 is an individual support plate. The two linear bodies 26 are attached so as to be parallel to each other at a predetermined interval at the portion where the portion 7 is engaged and fixed. Further, FIG. 5 (B) or FIG. As shown in (C), the belt-shaped heating element 8 is sandwiched between a pair of linear elements 26 integrated with the respective linear elements 24 in the support plate 7. It may be configured.

Furthermore, as a further characteristic component in the snow melting and heat retaining heat generating block 100 in the present invention, as shown in FIG. 1, at least a part of the bottom surface portion 9 of the substrate portion 1 includes: At least one leg portion that is formed in a protruding shape having a predetermined height from the bottom surface portion 9 and is integrally formed with the substrate portion 1 by the same constituent material as the constituent material of the substrate portion 1 11 is provided.

The effect of forming an appropriate drainage space is exhibited.

In particular, in the present invention, a plurality of the snow melting / warming heat generating blocks 100 are arranged adjacent to the arrangement setting region having a predetermined area, and then, as will be described later, each snow melting / heat retaining heat generating block 100. When the lead wire 12 for connecting to the power line provided in 100 and the operation to connect to the power line are performed, the construction site is set so that each snow melting / warming heat generating block 100 is not moved, displaced or deformed. However, the leg portion 11 can sufficiently achieve its purpose.

In order to increase the length, the length of one linear or belt-like long heating element 8 is set as long as possible, and the linear heating element 8 is placed on the upper surface portion 21 of the support plate 7. As shown in FIG. 8C, it is desirable to arrange them in a zigzag manner.

Furthermore, as a preferable specific example in the present invention, as shown in FIGS. 5 (A) to 5 (C), the belt-like heating element portion 8 having a flat cross-sectional shape is connected to a predetermined portion of the support plate portion 7. As shown in FIG. 5 (C), a pair of metal auxiliary members 24 erected close to each other in a direction orthogonal to the flat surface portion 21 of the support plate portion 7 are connected to the ground terminals at a plurality of locations. A metal auxiliary member 26 extended upward from the portion to be used is disposed, and the belt-like heating element portion 8 is perpendicular to the longitudinal direction of the band-like heating element portion 8 between the pair of metal auxiliary members 26. The belt-like heating element 8 can be easily fixed on the support plate portion 7 by passing it in a state where the width direction is upright, and more preferably, the belt-like heating element 8 is appropriately joined. The fixing means 113 is used to engage and fix the support plate portion 7. It is a desirable example.

It is desirable to set the snow melting / warming heat generating block 100 so that it can be easily separated and separated from the mold later.

Hereinafter, a specific example relating to the method for manufacturing the snow melting heat generating block 100 will be described.
That is, as a basic operation procedure of the manufacturing method of the snow melting heat generating block 100 according to the present invention, as is apparent from the above description, the support plate portion 7 and the linear or belt-like long heating element. After the portion 8 is set and arranged in the mold 110 in this order, the molding filler 115 that is liquefied from the upper open end of the mold 110 and containing the gravel and an optional bonding agent is added.

Then, for about 10 hours to 20 hours, the substrate part 1 that is semi-fixed is air-dried in a natural dry state without performing heat treatment, and the gravel is partially solidified. By taking out from the mold 110 and transporting it to an appropriate part and further air-drying for 6 to 24 hours, the substrate block 1 has a desired strength, and a heat-generating block 100 for melting and keeping heat is formed. is there.
That is, in the present invention, a predetermined power source is supplied before the fluid filler is injected and filled into the mold at the free end of the lead wire, or at an appropriate stage after the molding process. A method of attaching a connector part that can be joined to a wire in a watertight and detachable manner is adopted.

Since the heat melting block 100 for snow melting and heat insulation according to the present invention employs the technical configuration as described above, it exhibits the operational effects as described below, and at the same time It can be put to practical use in various fields using the effect.
That is, first, the most prominent configuration as a technical feature of the present invention is that a linear or belt-like long heating element 8 is built therein, and is molded by a banel main material mixed with gravel and an adhesive. A plurality of panel bodies molded in a row are arranged and installed, and the heat melting block 100 for snow melting and heat insulation according to the present invention has high water permeability of the panel body. It is a great feature that does not accumulate on the surface.

However, the snow melting / warming heat generating block 100 of the present invention is characterized in that the leg portion 11 is provided integrally with the substrate portion 1 on the back side of the substrate portion 1 of the snow melting / warming heat generating block 100. Therefore, when the snow melting / warming heat generating block 100 is arranged / constructed in a predetermined area, the leg 11 of the snow melting / warming heat generating block 100 is fixed to the roadbed base of the area. When the snow melting / warming heat generating block 100 is arranged in the predetermined area and the laying work is executed, the block 100 main body is made difficult to move, thereby facilitating the construction operation and shortening the construction period. It is possible to make it.

Furthermore, the snow melting and heat retaining heat generating block 100 according to the present invention basically employs an electric heat generating mechanism as the heat generating or heat retaining function, so that the operation is simple and easy to automate. Furthermore, since it is possible to use late-night discount power, the running cost is low, and the heat generation block for snow melting and heat insulation that can manage the electric system.
However, the linear or belt-like long heating element 8 used in the snow melting and heat retaining heating block 100 in the present invention sufficiently generates heat even at a low temperature. Since it has self-temperature controllability, it has a feature that a temperature control device such as a thermistor is not required.

Further, in the heat melting block 100 for snow melting and heat insulation according to the present invention, one block is miniaturized so that it can be carried by one worker or a general individual and is easy to construct. Although the range is not specified, for example, the width is 400 mm to 600 mm, the length is 800 mm to 2000 mm, and the height can be arbitrarily set within the range of 15 mm to 40 mm. Can be designed to have a weight in the range of 25 kg to 70 kg.
The heat melting block 100 for snow melting and heat insulation according to the present invention can be adjusted to the weight that can be held by one person by commercializing with the above specifications, so that the efficiency of laying work is improved and Since the efficiency is improved, it is possible to exert an effect that the construction period required for the construction of the block 100 at the site can be greatly shortened.

Further, in the snow melting / warming heat generating block 100 according to the present invention, by making the length of the block 100 in the width direction about 450 mm, the effect of being able to cope with the rounded portion is exhibited. Is also possible.

On the other hand, the linear or belt-like long heating element 8 used in the snow melting / warming heating block 100 in the present invention has a very simplified configuration as described above. In addition, there are almost no components that cause failure, and it is possible to sufficiently handle long-term practical use, and the main body of the heating element 8 is processed with Teflon (registered trademark), so it is durable. It has an effect that the heat-generating block 100 for snow melting and heat-retaining can be obtained, which is excellent in heat resistance and waterproofness, and has a quick rise in heat-generating temperature even at low temperatures.
The snow melting and heat retaining heating block 100 using the linear or belt-like long heating element 8 in the present invention can be designed to generate heat in the range of 30 to 35 ° C. desirable.

Further, in the snow melting / warming heat generating block 100 according to the present invention, the substrate portion 1 of the main constituent portion is constituted by a panel main material mixed with gravel and an adhesive, so that shear force Even if an external force is applied to the block 100, the block 100 according to the present invention is applied to a desired roadbed, and then the block 100 is applied to the block with an appropriate roller. It doesn't move or get destroyed.

In addition, the snow melting / warming heat generating block 100 according to the present invention, as will be described later, a plurality of the blocks 100 are arranged so as to be parallel to each other within a predetermined region, and an appropriate horizontal plane is defined. After that, the lead wire 12 led out from the side wall surface of each block 100 is appropriately tapped or lead wire of the power line connected to a preset external power source and appropriate waterproof and dustproof. By connecting via the connector part 14 having the connection, it is possible to easily and quickly perform the wire connection operation.
Of course, in the present invention, the connector portion 14 may be connected to the free end portion of the lead wire 12 in advance.

In the present invention, as described above, the block 100 can be easily and quickly arranged and constructed including electric wiring operations. Therefore, the construction is performed only on flat and straight terrain as in the past. Unlike conventional snow melting blocks, which can be used, it can be used in any place such as an area having a curve or a place where a slope is formed.
In other words, as mentioned above, snow removal on roads owned by public organizations such as national roads, prefectural roads, city roads, etc. is almost done by public institutions, but private roads or passages, and even private housing The parts on the site, such as the acroch passage from the entrance, the parking lot, the eaves, the stairs, etc., must be individually removed by the individual, but the frozen approach, the passage or the stairs etc. It is slippery and very dangerous for the elderly.
In the present invention, it is possible to quickly perform construction work at such a place at a safe and economical cost.

Furthermore, recently, the part where the sidewalk is connected to the sidewalk has become a slope due to the passage of bicycles, but if the slope part freezes, it will be recognized as a dangerous place because it will lead to a pedestrian falling. However, the snow melting / warming heat generation block 100 of the present invention is also applied to the slanted portion, while the snow melting / warming heat generation block 100 of the present invention is
There is a characteristic that the heating rate of the heating element rises quickly. Therefore, as soon as the heating system switch of the block 100 of the present invention is turned on, the temperature reaches a desired temperature. The snow in the vicinity melts, so if a person commuting by car accidentally notices that snow has accumulated in the morning, the snow melting operation can be performed in a short time. It is a convenient system for those who commute.

Further, in the heat melting block 100 for snow melting and heat insulation according to the present invention, by using night power with a low electricity bill, the snow melting of the snow during the night at the place where the block 110 is installed. Occurrence and anti-freezing operation can be performed, and snow falling from the roof can be melted using midnight power, so it is possible to melt and keep warm with low running costs. The heating block 100 for use can be obtained.
However, in the present invention, since gravel stone is used for the substrate portion 1, the heat retaining effect is high, and therefore the block 100 that has been subjected to heat generation using midnight power has the midnight power charge. Even after the set time has elapsed, it is possible to maintain a predetermined temperature condition for a while without additional power supply, reducing the amount of power used in the daytime. Since things are also true, a more economical snow melting system is provided.

Further, in the snow melting and heat retaining heat generating block 100 according to the present invention, the water generated by the snow melting efficiently passes through the holes formed in the substrate portion 1 so as to communicate with each other. Since it flows downward, the upper surface of the substrate part 1 is always maintained in a dry state, freezing does not occur, and therefore there is no danger of a slip accident.
In the present invention, it is sufficient that the water generated by the snow melting process as described above is absorbed into the ground from the lower surface of the substrate part 1, but depending on the case, the water between the substrate part 1 and the ground is sufficient. An appropriate drainage groove can be separately formed.
In addition, since the snow melting / warming heat generating block 100 according to the present invention has the remarkable effects as described above, for example, a step plate portion such as a residential land having an external staircase or a staircase portion of a park. If it is used, the stairs are simply removed from the snow, and the melted water is also permeated through the block main body, so that it is possible to effectively and economically prevent the snow from forming on the stairs or freezing by the melted water.

Furthermore, by utilizing the above-described many features of the block 100 according to the present invention, for example,
