Description

  The present invention relates to a method for measuring the temperature by heating two coated plates such as a heat-shielded coated plate and a non-heat-shielded coated plate on which a heat-shielding paint is applied and a heat-shielded coating film is formed, or two different heat-shielded coated plates. Further, the present invention relates to a heat-shielding effect comparative evaluation device for comparing and evaluating the heat-shielding effects.

  In recent years, the temperature of the global environment has risen remarkably, but the heat of the sunlight radiated to the building is shielded, the temperature inside the building is reduced to maintain an appropriate temperature, or the energy consumption required for cooling is reduced. There is an increasing demand for control.

  Conventionally, as a material for building walls, roofs, etc., a heat-shielding coating plate formed by applying a heat-shielding paint to form a heat-shielding coating film is used, or as a plate material for existing building walls, roofs, etc. There is known a technique in which a heat-shielding paint is applied to form a heat-shielding coating film to form a heat-shielding coated plate.

  Various heat-shielding paints are manufactured and sold by various paint manufacturers, and the heat-shielding effect of the heat-shielding coated plate formed by forming a coating with these heat-shielding paints can be measured by using a non-heat-shielding coated plate or other heat-shielding paint. If it can be easily evaluated compared to painted panels, it is possible to select the thermal barrier painted panel that has the greatest heat shielding effect, or to select the optimal thermal barrier for the place where the thermal barrier painted panel is applied in the building Painted plate can be selected. Further, it is possible to easily explain the heat shielding effect of the thermal barrier coating plate to the owner of the building.

  As a conventional example, a light source that radiates infrared rays and a coated plate in which one plate is coated with a non-thermal barrier paint on one side and a thermal barrier paint is coated on the other side (or a painted plate coated with a non-thermal barrier paint) And two coated plates coated with a thermal barrier paint), a temperature sensor attached to the back side of the painted plate (such as a thermistor attached to the back side of the painted plate), and a temperature display device connected to the temperature sensor A thermal barrier effect evaluation apparatus for a thermal barrier coating film, comprising: means for changing a relative distance between a light source and a coated plate; and means for changing an irradiation angle of infrared rays on the coated plate. A heat shielding effect evaluation device is known (see Patent Document 1).

Utility Model Registration No. 3166534

  A heat shielding effect evaluation device described in a conventional example (Patent Document 1) is a coated plate in which a coating film is formed by applying a non-heat shielding paint on one side of a plate and a heat shielding paint on the other side. This is a device for evaluating the heat-shielding effect of a painted plate coated with a paint and a painted plate coated with a heat-shielding paint), which has a thermistor or the like attached to the back side. Therefore, when a paint maker or the like evaluates the heat-shielding effect of the heat-shielding paint, it is suitable for evaluating a coated plate in which a thermistor or the like is pasted on the back side in advance.

  However, when a contractor or a painter applies multiple manufacturers, multiple types of thermal barrier paints, and non-thermal barrier paints to a sample plate at the site, and evaluates the thermal barrier effect of those painted plates one after another. Has to be attached to each of them, or, in some cases, must be peeled off from the already-evaluated painted plate and re-attached to another painted plate, which makes evaluation work difficult.

  Further, the heat-shielding effect evaluation device described in the conventional example applies a non-heat-shielding paint to one side of one plate and a heat-shielding paint to the other side for one light source as far as the description and the drawings are concerned. A coated plate with a coating film (or two coated plates, one coated with a non-thermal barrier paint and one coated with a thermal barrier paint) is arranged. Depending on the adjustment, the degree of light irradiation on the two painted plates is different, so that accurate evaluation of the heat shielding effect may not be obtained.

  At least, for a coated plate in which a coating is formed by applying a non-heat-shielding paint on one side and a heat-shielding paint on the other side of one plate, apply the non-heat-shielding paint and the heat-shielding paint on one plate, respectively. It is considered difficult to measure the temperature difference between the two parts with sufficient accuracy in order to conduct heat isothermally between the portions.

  The present invention provides a heat-shielding coated plate whose heat-shielding effect is evaluated by comparison, without attaching a thermistor or the like to a non-heat-shielding coated plate, simply by applying a heat-shielded coated plate or a non-heat-shielded coated plate to a predetermined shape. It is an object of the present invention to provide an easy-to-use heat-shielding-effect evaluating apparatus that can easily compare and evaluate the heat-shielding effect by simply placing the device on a location or coming into contact with or approaching a temperature sensor.

  An embodiment for implementing a thermal barrier effect comparison and evaluation device according to the present invention will be described below based on an embodiment with reference to the drawings.

  An embodiment of a thermal barrier effect comparative evaluation apparatus according to the present invention will be described with reference to FIGS. The heat-shielding effect comparative evaluation apparatus according to the present invention is a heat-shielding coated plate (a coated plate coated with a heat-shielding paint) and a non-heat-shielded coated plate (a coated plate coated with a non-heat-shielding paint) or two different types. This is a device for comparing and evaluating the heat shielding effect of two coated plates, such as two heat shield coated plates.

  As shown in FIG. 1, a heat-shielding-effect comparison / evaluation apparatus 1 according to the present invention includes a box-shaped case 2 with a lid, and a First and second heating lamps 3 and 4 as heaters and first and second temperature measurement and display devices 5 and 6 are provided in the first and second storage chambers 15 and 17 (see FIG. 2A). Are independently provided, and by opening the lid 7 of the box-shaped case 2, the irradiation conditions of the first and second heating lamps 3 and 4 are automatically adjusted without adjusting the irradiation conditions. In this configuration, the two heat-shielding coated plates are heated respectively, and can be subjected to a heat-shielding effect comparative evaluation.

  The box-shaped case 2 is formed as a rectangular box opened upward and can be opened and closed by a lid 7. In this embodiment, for convenience of explanation, the front side is defined as the front side of the box-shaped case 2, the rear side is defined as the depth side, and the left and right as viewed from the front side of the box-shaped case 2 is referred to as the left-right direction.

  The box-shaped case 2 and the lid 7 are formed of a material such as wood, a heat-resistant resin material, or a metal material (eg, aluminum material). Since wood has a relatively low thermal conductivity, if the box-shaped case 2 and the lid 7 are made of wood, heat dissipation outside the case can be relatively suppressed. In this embodiment, the box-shaped case 2 and the lid 7 are formed of wood.

  The box-shaped case 2 has left and right side plates 11, a front plate 12, a back plate 13 and a bottom plate 14, as shown in FIGS. 1, 2 (a) and 2 (b). It is a long rectangle in the left-right direction. The box-shaped case 2 is divided into a first storage chamber 16 and a second storage chamber 17 on the left and right sides by a partition plate 15 at the center in the longitudinal direction (the left-right direction in the figure) in plan view. The first and second storage chambers 16 and 17 have the same configuration (the same size, structure, and the like).

  In the first and second storage chambers 16 and 17, a heat insulating material is arranged along the bottom surface and the inner peripheral surface, respectively. As the heat insulating material, a heat insulating resin material, a ceramic heat insulating material, or the like is used. In this embodiment, a foamed heat-insulating resin material 21 (for example, a styrene foam plate) is used as a heat-insulating material, and a space surrounded by the heat-insulating resin material 21 is formed.

  Here, the “inner peripheral surface” of the first and second storage chambers 16 and 17 is the side plate 11 (the left side plate 11 for the first storage room 16 and the right side plate for the second storage room). 11), an inner peripheral surface of a portion composed of the front plate 12, the partition plate 15, and the back plate 13. The “bottom surface” is the inner surface of the bottom plate 14.

  The heat-insulating resin material 21 is provided on the inner surfaces of the bottom plate 14, the side plate 11 (the left side plate 11 for the first storage room 16, the right side plate 11 for the second storage room), the front plate 12, and the back plate 13. Are arranged in contact with each other.

  Then, as shown in FIGS. 1, 2 (a) and 3 (a), in the first and second storage chambers 16 and 17, the heat insulating resin material 21 is partitioned along the partition plate 15 respectively. It is arranged with a slight gap between it and the plate 15. This gap can be used as a storage gap 22 in which a painted plate whose heat-shielding effect is comparatively evaluated can be stored or temporarily placed by being inserted from above.

  In the first and second storage chambers 16 and 17, the heat-insulating resin material 21 is arranged so as to be detachably fitted along the inner peripheral surfaces of the first and second storage chambers 16 and 17, respectively. Configuration.

  The front and rear and left and right heat-insulating resin materials 21 which are removably fitted along the inner peripheral surfaces of the first and second storage chambers 16 and 17 respectively become rectangular in plan view when fitted. The size in the circumferential direction (width direction) is determined. By slightly increasing the size, the heat-insulating resin materials 21 adjacent to each other are fitted together with the heat-insulating resin material 21 fitted along the inner peripheral surface. Further, the end surface of the heat insulating resin material 21 and the inner surface of the storage chamber (for example, the front and rear end surfaces of the heat insulating resin material 21 on the left side of the storage room 16 and the inner surfaces of the front plate 12 and the back plate 13) make contact. , So that frictional resistance occurs and the fitting does not come off.

  With such a configuration, the heat-insulating resin material 21 can be removably fitted into the first and second storage chambers 16 and 17 without providing any particular mounting means, In the inserted state, the fitted state is loosened and it is difficult to come off the inner peripheral surface.

  Although not shown, a hook side (or a ring side) of the hook-and-loop fastener is stuck to the inner surface of the box-shaped case 2, and a ring side (or a hook side) of the hook-and-loop fastener is stuck to the outer surface of the heat insulating resin material 21. A configuration may be adopted in which the heat insulating resin material 21 is detachably attached to the inner peripheral surface and the bottom of the storage chamber with these surface fasteners.

  With such a configuration, the heat-insulating resin material 21 can be replaced in maintenance or the like. Further, as described later, the data lines 49 of the first and second temperature measurement display devices 5 and 6 are Depending on the length, it is possible to crawl appropriately between the heat insulating resin material 21 and the front plate 12 and between the heat insulating resin material 21 and the bottom plate 14 of the box-shaped case 2.

  In the first and second storage chambers 16 and 17, a frame plate 23 is placed and arranged on the upper surface of the heat insulating resin material 21 arranged along the inner peripheral surface. The frame plates 23 respectively disposed for the first and second storage chambers 16 and 17 are a left frame plate, a right frame plate, a front frame plate, and a rear frame plate.

  For the first storage room 16, the right frame plate 23 is disposed on the heat insulating resin material 21 along the partition plate 15, and for the second storage room 17, the left frame plate 23 is mounted on the partition plate 15. Along with the heat-insulating resin material 21.

  As shown in FIGS. 1 and 2A, the lid 7 is attached to the upper end of the back plate 13 via a hinge 24 so as to be openable and closable on the box-shaped case 2. A foldable support arm 25 is attached between the left and right inner surfaces of the lid 7 and the inner surfaces of the left and right side plates 11 of the box-shaped case 2. In the opened state, the box-shaped case 2 can be maintained at a predetermined angle.

  The support arm 25 has upper and lower two arms 26 and 27 rotatably attached to the lid 7 and the left and right side plates 11 respectively. The two arms 26 and 27 are rotatable with each other and open the lid 7. Are connected by a connecting portion 28 so that they can be locked to each other in the folded state. The connecting portion 28 between the two arms 26 and 27 may use a known structure. For example, the following configuration shown in FIGS.

  The connecting portion 28 has a pivot shaft 29 and rotatably connects the two arms 26 and 27 to each other. In the connecting portion 28, one arm 26 is attached to the other arm 27 by a spring 30. When urged, a pin 31 is provided, and a stop hole 32 into which the pin 31 can be fitted is formed in the other arm 27.

  3 (e), the arms 26, 27 are rotated relative to each other to open the lid 7, and as shown in FIG. 3 (f), when the pin 31 is fitted into the stop hole 32, the two arms 26, 27 The rotation of the support arm 25 is restricted, and the support arm 25 is maintained at a predetermined angle with respect to the box-shaped case 2 with the lid 7 opened as described above. When the lid 7 is pushed and closed, the pin 31 withdraws from the stopper hole 32 to the state shown in FIG.

  As a connecting portion for maintaining the arms 26 and 27 at a predetermined angle from each other, instead of urging the pin 31 with the spring 30 as described above, the ball is urged by a leaf spring provided on one arm. Alternatively, a known structure that engages with a hole or a groove provided in the other arm may be used. Next, a specific example of the structure of the connecting portion using such a leaf spring will be described.

  The connecting portion 33 shown in FIGS. 4A to 4D enables the upper and lower arms 26 and 27 to be rotatable with respect to each other on a pivot shaft 29, and provides a circular concave portion 34 on the inner surface of the upper arm 26. A stopper hole (or stopper groove) 35 is formed therein. The lower arm 27 is provided with a retractable hole 37 into which an engagement ball 36 can be fitted and retracted so as to correspond to the stop hole 35. Rivet or the like, and the peripheral side is provided in a free state without being fixed to the lower arm 27 so as to be elastically contacted.

  According to such a connecting portion 33, when the upper and lower arms 26 and 27 are not maintained at a predetermined angle, as shown in FIG. The ball 36 is urged from the hole 37 toward the inner surface of the concave portion 34 of the upper arm 26. In this state, the upper and lower arms 26 and 27 can rotate with respect to each other about the pivot 29.

  During this rotation, the engagement ball 36 moves circumferentially along the inner surface of the concave portion 34 of the upper arm 26 while being fixed to the lower arm 27 by the fixing hole 39. The upper and lower arms 26 and 27 rotate with respect to each other, and the engagement ball 36 is inserted into a stop hole 35 formed in the concave portion 34 of the upper arm 26 from the retractable hole 37 as shown in FIGS. 4C and 4D. , The upper and lower arms 26 and 27 stop rotating and are maintained at a predetermined angle from each other.

  The first and second heating lamps 3 and 4 have the same performance and the same specifications (radiation energy, wavelength, heating performance, required power, etc.), and any light source serving as a heater can be used. Although such a lamp may be used, in this embodiment, a far-infrared lamp is used as a heating lamp. Each of the first and second heating lamps 3 and 4 is provided with a power cord 40 connected to a power source. Although not shown, the power cord 40 is preferably configured to be attachable to the lid 7 so that the power cord 40 does not catch fire or the like by contacting the first and second heating lamps 3 and 4.

  When the lid 7 is opened at a predetermined angle and maintained by the support arm 25 as described above, the first and second heating lamps 3 and 4 are distant downward as shown in FIG. It is fixed to the inner surface of the lid 7 by a mounting rod 41 so as to emit infrared rays.

  As will be described later, the two painted plates (first and second painted plates) for which the heat shielding effect is to be compared and evaluated are first and second storage chambers 16 and 17 at the time of temperature measurement. The irradiation angles of the heating lamps 3 and 4 are fixed to each other with respect to these two coated plates, for example, the irradiation angles of the heating lamps 3 and 4 are set. The heating lamps 3 and 4 are mounted on the inner surface of the lid 7 by the mounting rods 41 so that the optical axis is substantially 90 ° with respect to the painted plate, and the heating conditions are the same.

  The heating lamps 3 and 4 have a configuration in which the irradiation angle of the mounting rod 41 with respect to the coating plate on the frame plate 23 can be adjusted by initial setting by the mounting rod 41 (for example, the mounting rod 41 is formed by two or more members). It is also possible to employ a configuration in which the fixed angles can be adjusted.

  However, after the initial setting, except for the case where the maintenance angle is required, such as when the irradiation angle is displaced for some reason, it is possible to make the structure unnecessary for adjustment again by opening the lid 7, Immediately, the two coated plates are heated by the heating lamps 3 and 4 under the same conditions, and the characteristic of the present invention that the temperature can be measured can be utilized, which is preferable.

  In addition, as shown in FIG. 1, by attaching the safety enclosure 42 to the first and second heating lamps 3 and 4, a user or the like contacts the heating lamps 3 and 4. Prevent burns.

  When the lid 7 is closed when the heat-insulating-effect comparative evaluation device 1 is not used, the first and second heating lamps 3 and 4, the power cord 40 related to the heating lamps 3 and 4, the safety enclosure 42 and the mounting rod The configuration, dimensions, etc. of 41 are determined so as to be stored in the first and second storage chambers 16, 17 of the box-shaped case 2.

  As shown in FIG. 1, FIG. 2 (a), (b), and FIG. 3 (a), the first and second temperature measurement display devices 5 and 6 respectively include a temperature sensor 47, a temperature display 48, and a data line. 49, the measurement data obtained by the temperature sensor 47 is transmitted to the temperature display 48 via the data line 49, and the temperature display 48 is configured to digitally display the measured temperature based on the measurement data. I have. In addition, what is necessary is just to use a well-known temperature measurement display apparatus as the temperature measurement display apparatuses 5 and 6 of such a structure.

  In this embodiment, the temperature indicator 48 is provided outside the box-shaped case 2 as shown in FIGS. 1, 2A, and 2B, and is detachably attached to the front plate 12 by a mounting means. It is installed. Various configurations are conceivable as the mounting means. For example, in the present embodiment, the following configuration is adopted.

  As shown in FIGS. 3B and 3C, a keyhole-shaped fitting hole 54 (a lower round hole and an upper slot having a width smaller than the diameter of the round hole) are formed on the back surface (rear surface) of the temperature indicator 48. Are formed integrally with each other, and projections 55 each having a head 56 (a diameter smaller than the round hole and larger than the width of the groove hole) are provided on the left and right front surfaces of the front plate 12, respectively. The temperature indicator 48 is attached to the front plate 12 by fitting the projection 55 to the front plate 12 so that the projection 55 can be prevented from coming off and can be detachably attached.

  As another mounting means, a notch 59 is formed in a part of each of the right and left upper ends of the front plate 12 as shown in FIG. The temperature indicator 60 may be fitted. The configuration of the heat-insulation-effect comparative evaluation device 58 is the same as that of the heat-insulation-effect comparative evaluation device 1 except for the means for mounting the temperature indicator 60.

  As another mounting means, although not shown, a magnet may be attached to the front plate 12 or the temperature indicator 48, and a magnet adsorbing material such as an iron plate may be attached to the temperature indicator 48 or the front plate 12 so as to be detachable. Good.

  As the temperature sensor 47, a thermistor, a platinum resistance temperature detector, or the like is used. As shown in FIGS. 2 (a), 2 (b) and 3 (a), in the first and second storage chambers 16 and 17, the mounting pieces 65 for mounting the temperature sensors 47 are made of a heat insulating resin material. 21 and is attached to the front plate 12 of the box-shaped case 2.

  The tip of the mounting piece 65 is provided in the storage chambers 16 and 17 so as to extend horizontally, and the temperature sensor 47 can be detachably attached to the tip at the tip thereof. Specifically, as shown in FIG. 3A, the tip of the mounting piece 65 is provided with a keyhole-shaped mounting hole 66 (in the same way as the fitting hole 54 from the circular hole and the groove hole) in a plan view. A temperature sensor 47 having a large-diameter portion 67 can be detachably mounted in the mounting hole 66 (see FIGS. 2B and 3A).

  The configuration in which the temperature sensor 47 is attached to the mounting piece 65 has the following configuration in relation to two painted plates (first and second painted plates) for which the temperature measurement or the heat shielding effect is comparatively evaluated. I do. For example, a heat-shielding coated plate 68 (first coated plate) and a non-heat-shielded coated plate 69 (second coated plate) for comparatively evaluating the heat-shielding effect are placed in the first and second storage chambers 16 and 17, respectively. 2 (a) and 2 (b), it is placed on the upper surface of the frame plate 23 and set horizontally. In this setting state, the temperature sensor 47 It is configured to be mounted on the mounting piece 65 at a height that abuts on the back surface of the coating plate 69 (the lower surface opposite to the side on which the coating film is formed).

  In short, in the thermal barrier effect comparison and evaluation device 1 according to the present invention, the temperature sensor 47 is not attached to the painted plate itself for measuring the temperature as in the conventional example, but is painted at the time of temperature measurement. When the plate is set in the heat-insulating-effect comparison / evaluation apparatus 1, it automatically comes into contact with the back surface of the painted plate. Therefore, according to the present invention, it is possible to easily measure the temperatures of a plurality of different coated plates one after another. Note that the temperature sensor 47 may be configured to measure the temperature immediately below the painted plate as a configuration (for example, a configuration separated from the painted plate by about 5 to 20 mm) instead of making contact with the painted plate.

In this embodiment, the front plate 12 of the box-shaped case 2 is shown in FIGS. 2A, 2B and 3A corresponding to the first and second storage chambers 16 and 17, respectively. As described above, the insertion hole 74 having a size that allows the temperature sensor 47 and the data line 49 to pass through is formed, and the temperature sensor 47 and the data line 49 pass through the insertion hole 74 so as to pass through the first and second storage chambers 16 and 17. Has been introduced within.

  As shown in FIGS. 2A, 2B and 3A, the data lines 49 introduced into the first and second storage chambers 16 and 17 correspond to, for example, The temperature sensor 47 is arranged so as to extend between the plate 12 and the bottom plate 14 and the heat insulating resin material 21, and the temperature sensor 47 is attached to the attachment piece 65 as described above. The gap between the insertion hole 74 and the data line 49 is closed by inserting and inserting a removable embedding material 75 (for example, a soft resin material).

  As described above, in the present embodiment, the temperature indicators 48 of the first and second temperature measurement and display devices 5 and 6 are provided outside the box-shaped case 2, and the data lines 49 are provided inside the box-shaped case 2. Is connected to the temperature sensor 47 provided at

(Operation) The operation of the thermal barrier effect comparison and evaluation device 1 having the above configuration will be described below. When not in use, the heat-insulating-effect comparison / evaluation apparatus 1 includes the first and second heating lamps 3 and 4, the power cord 40, the safety enclosure and the mounting rod 41, respectively, in the first and second boxes of the box-shaped case 2. And the lid 7 is closed. The temperature indicator 48 is preferably mounted on the front plate 12 of the box-shaped case 2.

  For example, when visiting a customer site, an exhibition, or the like, the difference in the heat shielding effect between the heat-shielding coated plate 68 (first coated plate) and the non-heat-shielded coated plate 69 (second coated plate) is compared. In the case where the comparison is empirically described by the evaluation device 1, the heat-shielding coating plate 68 and the non-heat-shielding coating plate 69 may be stored in the storage gaps provided in the first and second storage chambers 16 and 17, respectively. It is very convenient to store it in 22.

  As described above, since the heat-shielding-effect comparative evaluation device 1 can store the first and second heating lamps 3, 4 and the like in the box-shaped case 2, the use site (for example, It is easy to handle such as transport to customers, exhibition venues, etc., painting sites, etc., storage and storage in the office.

  In use, as shown in FIG. 1, when the lid 7 is kept open at a predetermined angle with respect to the box-shaped case 2 by the support arm 25, the first and second heating lamps 3, 4 are turned on. They are automatically set at the same irradiation angle toward the first and second storage chambers 16 and 17.

  Then, for example, the heat-insulating coating plate 68 and the non-heat-shielding coating plate 69, which are targets for comparative evaluation of the heat insulating effect, are placed on the upper surfaces of the frame plates 23 of the first and second storage chambers 16 and 17, respectively. It is placed with the painted surface facing upward and set horizontally (see FIGS. 2A and 2B).

  Then, the upper ends of the temperature sensors 47 provided in the first and second storage chambers 16 and 17 are respectively connected to the back surfaces of the thermal barrier coating plate 68 and the non-thermal barrier coating plate 69 (the side opposite to the side on which the coating film is formed). Automatically contacts the lower surface of the Then, when the first and second heating lamps 3 and 4 are connected to a power source via the power cord 40, the first and second heating lamps 3 and 4 dispose far infrared rays with the heat-shielding coating plate 68. The thermal barrier coating plate 69 is evenly irradiated and heated.

  When the heat-shielding coated plate 68 and the non-heat-shielding coated plate 69 are heated in this way, the temperature rises in several minutes to about 10 minutes, and the temperature is measured by the first and second temperature measurement display devices 5 and 6, respectively. The data is digitally displayed on the temperature display 48. The heat-shielding coated plate 68 exhibits a heat-shielding effect as compared with the non-heat-shielding coated plate 69, and the temperature of the back surface is measured lower.

  The temperature of the heat-shielding coated plate 68 and the temperature of the non-heat-shielding coated plate 69 are measured using the heat-shielding effect comparative evaluation device 1 and compared with the temperature indicators 48 of the first and second temperature measurement display devices 5 and 6. By doing so, it is possible to evaluate that the heat-shielding coated plate 68 has a heat-shielding effect as compared with the non-heat-shielding coated plate 69, and how much the heat-shielding effect is different. The thermal effect can be empirically and visually shown and explained to a customer or the like.

  As described above, not only can the thermal barrier effect of the thermal barrier coating plate 68 and the thermal barrier effect of the non-thermal barrier coating plate 69 be compared, but two different thermal barrier coating plates (first and second It is placed and set on the upper surface, heated by the first and second heating lamps 3 and 4, and the temperature is measured by the first and second temperature measurement display devices 5 and 6, respectively. The heat shielding effect of the painted plate can be compared and evaluated.

  As described above, according to the heat-insulating-effect comparative evaluation apparatus 1 according to the present invention, the two painted plates are placed on the upper surfaces of the frame plates 23 of the first and second storage chambers 16 and 17 with the painted surfaces facing upward. The upper end of the temperature sensor 47 abuts on the back surface of the painted plate, so that the temperature sensor is attached to the back surface of the painted plate for measuring the temperature, as in the prior art. It is very easy to compare and evaluate the heat insulation without doing anything.

  Further, according to the heat-shielding effect comparative evaluation apparatus 1 according to the present invention, by opening the lid 7, the first and second heating lamps 3 and 4 allow the two coated plates to compare the heat-shielding effect. Since the setting can be performed in the same direction with the same irradiation angle and the same heating condition, it is not necessary to perform an adjustment operation such as adjusting the irradiation angles of the first and second heating lamps 3 and 4 to the same condition. When the initial adjustment of the irradiation angle of the heating lamp is required, once the initial adjustment is performed, it is not necessary to adjust the irradiation angle each time the lamp is used thereafter.

  By the way, when the two coated plates are heated by the first and second heating lamps 3 and 4, respectively, the insides of the first and second storage chambers 16 and 17 below the coated plate become hot and heat. The heat is confined, and the heat is conducted and dissipated to the box-shaped case 2 or the periphery of the box-shaped case 2, which is not preferable for the user.

  According to the heat-insulating-effect comparative evaluation apparatus 1 according to the present invention, the first and second storage chambers 16 and 17 have the heat-insulating resin material 21 arranged along the inner peripheral surface and the bottom surface, respectively. 2 or the conduction and dissipation of heat to the periphery of the box-shaped case 2 can be reduced, and the user can use it with confidence.

  Further, by providing the heat-insulating resin material 21, the temperature sensors 47 in the first and second storage chambers 16 and 17 can be controlled by the temperature of the coated plate under uniform conditions without being influenced by the external temperature. Measurement becomes possible.

  When the temperature measurement display devices 5 and 6 are used for a long time, the temperature sensor 47 may be deteriorated, and the measurement accuracy may be reduced. Therefore, when replacing the temperature measurement and display devices 5 and 6 with new ones at the time of maintenance or the like of the heat shielding effect comparison / evaluation device 1, the embedded material 75 is removed from the insertion hole 74, and the temperature sensor 47 is removed from the mounting piece 65. Then, the heat-insulating resin material 21 at least on the front side of the first and second storage chambers 16 and 17 is partially or entirely removed from the storage chambers 16 and 17 as necessary.

  Then, the data line 49 and the temperature sensor 47 are taken out of the box-shaped case 2 through the insertion hole 74, and a new temperature sensor 47 and the data line 49 are introduced into the storage chambers 16 and 17 from the insertion hole 74 instead. The length of the data line 49 is appropriately adjusted along the heat insulating resin material 21 and the inner surface of the box-shaped case 2 (the front plate 12 and the bottom plate 14 of the box-shaped case 2).

  After that, the heat insulating resin material 21 is arranged along the bottom surface and the inner peripheral surface of the box-shaped case 2, and the data line 49 is arranged between the box-shaped case 2 and the heat insulating resin material 21. Is attached to the mounting piece 65.

  As described above, the embodiment for implementing the thermal barrier effect comparison and evaluation device according to the present invention has been described based on the embodiments. However, the present invention is not limited to such embodiments, and is described in the claims. It goes without saying that there are various embodiments within the scope of the technical matters described.

  In the present invention, two sets each including a storage room, a heating lamp, and a temperature measurement and display device are arranged in one box-shaped case, but one heating lamp and one temperature-measurement display are arranged in one box-shaped case. If a heat insulating resin material is arranged along the inner surface of the storage room and the painted plate is placed on the upper surface of the left, right, front and rear frame plates as in the present invention, a heat shield that contacts the temperature sensor is provided. It can be modified to an effect evaluation device.

  Since the heat-shielding effect comparative evaluation apparatus according to the present invention has the above-described configuration, it can be used not only for evaluating the heat-shielding effect of a painted plate, but also for other building materials (wall plates, outer wall plates, etc.), members of general equipment, and the like. It can also be applied to the comparative evaluation of the thermal barrier effect and thermal conductivity of the material.
