Description

  The present invention relates to an exothermic panel material for construction that proposes a new use of sheet-like carbide according to the applicant's patented invention, and a method for manufacturing the same. The exothermic panel material has a radio wave shielding property in addition to the exothermic effect.

  Except for a special building such as a log house, a general building is composed of a frame member, a roof material to be attached using the frame member, and a panel material for exterior and interior. Such a basic configuration does not change greatly whether the building is made of reinforced concrete or wooden. The building blocks the external environment and the internal environment by the cooperative action of these members, and is suitable for the use of the building in the building, and in the building, the human activity environment suitable for the use of each room. It is intended to provide. The lighting equipment, the air conditioning equipment, and the air conditioning equipment have a function to assist this purpose.

  The present invention seeks to find a new application of the product according to the patented invention, and is not aware of the problems of specific prior art. The aim of the present invention is to be aware of the following problems on the premise of providing a more appropriate or more comfortable environment in relation to the use and usage of the building or each room. .

In an acoustic measurement room, when an air conditioning system is used, the wind noise of the air blown out of the duct and the resonance sound of the duct may adversely affect the measurement result as low frequency noise. In such a room, measures are taken such as attaching a blindfold plate in which a sound absorbing material is set at the outlet of the duct, but it is difficult to completely suppress noise. This problem will be solved if the measurement operator is equipped with an external operation room that can operate each measuring instrument from outside the room.
Even in public industrial test sites, etc., there will be no facilities to the external operation room.

  In a room for electrical measurement that handles weak currents, there is a problem that noise is mixed into the measurement result due to external radio waves flying in the air. Even this problem can be solved by installing a full-scale anechoic chamber, but the equipment fund is extremely expensive compared to a room for general use.

  It is not a special example as described above, and the operation noise of air conditioning and air conditioning equipment and the presence of the equipment itself are troublesome even in ordinary homes. And since these apparatuses cannot be installed or installed in every room, it cannot be avoided that the location which cannot receive the effect of these apparatuses arises in a bathroom, a toilet, a kitchen, etc., for example.

  The present invention solves the problem of annoyance due to the presence of the device itself, the problem of the operation noise of the device, and the problem that the location where the effect of the device does not reach, at least on the heating surface, and the electrical measurement room and the audio room, The purpose of the present invention is to provide an exothermic panel material for buildings that can also exhibit radio wave shielding properties and a method for manufacturing the same in buildings and rooms for special uses that do not like the arrival of external radio waves such as computer rooms. .

  As means for achieving this object, the present invention adopts the following configuration.

  The building exothermic panel material according to claim 1 of the present invention has a knitted fabric or woven fabric sheet between a nonflammable back panel plate and a front panel plate suitable for interior use of a building. Sandwiching a carbonized sheet-like carbide and an electrode, and integrating them into a three-layer structure under a pressurized condition via a heat-resistant and insulating adhesive, and allowing the sheet-like carbide to function as a planar heater Features.

  Carbon is a conductor having a predetermined electric resistance. Accordingly, the sheet-like carbide is a planar conductor. In addition, the sheet-like carbide having a knitted fabric structure or a woven fabric structure is a planar conductor including voids, and the electric resistance value can be changed depending on the void ratio. And about the space | gap contained in a sheet-like carbide | carbonized_material, it can set freely by changing the knitting density of a knitted fabric structure or the woven density of a woven fabric structure. Therefore, the sheet-like carbide having a knitted fabric structure or a woven fabric structure has electrical characteristics that can function as a planar heater, but the sheet-like carbide, which is simply a group of carbon grains, has weak mechanical properties, It cannot be used alone. However, the sheet-like carbide in this configuration is sandwiched between the nonflammable front panel plate and the back panel plate together with the electrode via a heat-resistant and insulating adhesive, and the sheet-like carbide itself is mechanically A structure that does not require strength is realized. When the sheet-like carbide is energized, the generated heat is transmitted to the front panel plate and the back panel plate, and the entire panel plate can function as a single sheet heater. And, for the risk of electric leakage and fire of the exothermic panel material used in the predetermined place of the building, while making the front panel plate and the rear panel plate nonflammable, an adhesive for integrating the two is used. It is dealt with by making it heat-resistant and insulating. In addition, since the sheet-like carbide | carbonized_material of an exothermic panel material is electroconductivity, it can exhibit high radio wave shielding property by taking appropriate earth ground.

  The building exothermic panel material according to claim 2 of the present invention is characterized in that the sheet-like carbide is formed by carbonizing a Japanese paper yarn with a knitted fabric or a woven fabric.

  Sheet-like carbide is obtained by knitting or knitting carbon-containing strands or winding a knitted fabric or woven fabric in a roll shape and carbonizing in a carbonization furnace. Tissues or textures are extremely difficult to handle because they collapse very easily. For example, the material carbonized in a roll shape collapses in a work stage where the material is unrolled planarly. The use of Japanese paper yarn was adopted as a means to prevent this, and the carbonization of Japanese paper yarn having long tough vegetable fibers can exhibit a form maintaining ability to withstand moderately careful handling. it can.

  The building exothermic panel material according to claim 3 of the present invention is characterized in that the surface panel plate is a perforated panel plate in which a large number of through holes are arranged.

  The exothermic panel material that employs a perforated panel plate as the front panel plate is in a state in which the sheet-like carbide responsible for the heat generating action is exposed at the positions of many through holes. In comparison, the rise time of the ambient temperature after energization can be shortened, and since the surface area in contact with air is large, the entire room can be efficiently warmed.

  According to a fourth aspect of the present invention, there is provided a method for manufacturing an exothermic panel material for architecture, wherein a heat-resistant and insulating adhesive is thinly applied to one side of a back panel plate in a horizontal posture, and then applied to the back panel plate. A surface panel board in which a sheet-like carbide is spread, a tape-like electrode is arranged at a predetermined position of the sheet-like carbide, and a heat-resistant and insulating adhesive is thinly applied on one side on the sheet-like carbide and the electrode. It is characterized by overlapping and pressing for a predetermined time for integration.

  In addition, the usage order of the front panel board and the back panel board in the manufacturing method of the exothermic panel material for building can also be changed and manufactured. This is because there is only a difference between assembling from the front side or from the back side. The same applies to the order of the sheet-like carbide and the tape-like electrode. By this method, any exothermic panel material for buildings according to claims 1 to 3 can be manufactured.

  The exothermic panel material for building according to the present invention sandwiches a sheet-like carbide having a knitted fabric structure or a woven fabric structure between a non-flammable front panel plate and a non-flammable back panel plate so as to be energized, By making it possible to operate the sheet-like carbide as a planar heater while suppressing the weakness of the fragile sheet-like carbide, by using this exothermic panel material in a place of a building where normal heating is difficult or By using it in any part of the building as an auxiliary to normal heating, a silent and pollution-free heating effect can be exhibited. Moreover, the indoor environment with a high radio wave shielding property can be formed by using it as an interior panel for the entire building as required.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a building exothermic panel material according to the present invention and a method for manufacturing the same will be described with reference to the drawings.

  The exothermic panel material 50 for construction is mainly composed of the front panel plate 10, the back panel plate 30, and the sheet-like carbide 20 sandwiched between them (FIGS. 1 and 2).

  The requirement for the front panel plate 10 and the back panel plate 30 is that it is a non-combustible surface material suitable for the interior of a building, and a plaster board, a plaster plaster, and a calcium silicate plate are suitable materials. Asbestos-based panel boards also meet the requirements, but they are not used because they cause disease. In the present embodiment, a calcium silicate plate is used as the front panel plate 10 and a gypsum board is used as the back panel plate 30. In addition, although there exist a non-porous thing and a perforated thing in a calcium silicate board, the perforated thing which arranged many through-holes here is used.

  The sheet-like carbide 20 is a sheet-like carbide formed by carbonizing a knitted fabric or woven fabric sheet. Here, a carbonized sheet of a woven fabric structure in which wefts 22 and warps 21 are woven into a plain weave is used. For the material of the weft 22 and the warp 21, it is required to use a material that is excellent in form maintainability after carbonization.

  An example of the material of the weft 22 and the warp 21 that satisfies this condition is a Japanese paper yarn. Washi yarn refers to a product obtained by spinning strong plant-derived long fibers derived from Kozo, Mitsuma, Ganpi and the like. In addition, fibers such as Asa, palm, and palm can also be used. In addition, it is preferable that the weaving width W1 when weaving a sheet having a textured structure is woven in accordance with either the vertical dimension or the horizontal dimension of the front panel plate 10 or the back panel plate 30. Thereby, it is possible to omit the number of cutting steps when the exothermic panel material 50 is manufactured.

  The exothermic panel material 50 is manufactured as follows, for example (FIG. 3). First, the back panel plate 30 is placed horizontally, and a heat-resistant and insulating adhesive is thinly applied to the surface. As the adhesive to be used, a silicone rubber-based adhesive is suitable. In addition, a water glass adhesive can be used without any problem.

  On the back panel plate 30 to which the adhesive is applied, the sheet-like carbide 20 is spread out by unrolling the roll. Specifically, a temperature sensor 24 that is a thermocouple and a pair of tape-like electrodes 23 and 23 are arranged on the spread sheet-like carbide 20. In addition, it can replace with the tape-shaped electrode 23 and can also arrange | position directly, removing what removed the coating | cover of the electrical cable whose core wire is a strand wire.

  Finally, the front panel plate 10 having the above adhesive thinly applied on the back surface is placed on the sheet-like carbide 20 and left to stand for a predetermined time until the pressure is applied and the adhesive is stabilized. In order to apply the pressure P, it is preferable to use a pressing device for building materials, but it is also possible to adopt a convenient means for stacking and pressurizing unused materials or already completed exothermic panel materials 50. .

  The sheet-like carbide 20 in the completed exothermic panel material 50 functions as a kind of planar heater by energizing the pair of electrodes 23, 23, and as a result, the entire exothermic panel material 50 functions as a planar heater. . The sheet-like carbide 20 generates heat as a planar heater because the sheet-like carbide 20 is a continuous structure of carbon particles, and the heat generation principle is Joule heat itself.

  However, in actual use of the exothermic panel material 20, it is necessary to be able to manage the temperature from the viewpoint of safety and the like. Therefore, the exothermic panel material 50 is controlled by simple feedback control using the temperature sensor 24 and the setting device 25. Use. The functions required for the setting device 25 are an external setting function that can set an arbitrary temperature, a comparison function that compares temperature information from the temperature sensor 24 with the set temperature, and a power supply intermittent function. It is obvious as a temperature control device attached to the equipment. The setting device 25 may be accompanied by a timer. In this case, the setting device 25 can be automatically energized at a desired time, which is convenient.

  Such an exothermic panel material 50, for example, in an ordinary house, is used as an interior material for a toilet WC or the like that does not have a heating effect (FIG. 4), thereby contributing to a comfortable environment as well as a rapid body. It is also possible to prevent a seizure disorder of the circulatory system due to chilling. In particular, the exothermic panel material 50 using the surface panel plate 10 in which the through holes 12 are arranged has a rapid rise in ambient temperature, so that practical heating is possible even when energized several minutes before use. There is an effect.

In addition, although illustration is abbreviate | omitted about the case where the exothermic panel material 50 is utilized as an electromagnetic wave shielding member, in order to exhibit a sufficient effect, the exothermic panel material 50 is arrange | positioned so that the whole room may be surrounded. It is preferable. However, since the properties of the radio wave reflectivity, wraparound, absorption, etc. differ depending on the frequency band of the external radio wave, even when the exothermic panel material 50 is used in a part of the room, an effect proportional to the use area can be obtained. There are many cases. Further, the electrodes 23 and 23 in the case where the exothermic panel material 50 is used as a radio wave shielding member can be effectively used as a grounding terminal.
