Description

  The present invention is a building material peeling heater for use in heating and peeling building materials such as road marking materials and adhesive panels arranged on predetermined screens such as road surfaces, wall surfaces, floor surfaces, and ceiling surfaces in buildings. And the building material peeling method.

In buildings such as houses and commercial facilities, wall surfaces, floor surfaces, ceiling surfaces, and the like are ward screens that divide the room, and various building materials are affixed to the ward screens. The building material in this case is also called a P tile (plastic tile) or a cushion floor, and is attached to a wall surface, a floor surface, a ceiling surface, or the like with an adhesive such as an epoxy adhesive or a urethane adhesive.
Further, in the building, there is a road surface such as an indoor parking lot as a predetermined section screen, and the road surface made of concrete, asphalt or the like has a road marking material (STOP characters indicating parking position and parking position) among various building materials. A white or yellow line indicating the color) is applied or affixed. In the present specification, a road marking material, an adhesive panel, and the like arranged on a predetermined section screen such as a road surface, a wall surface, a floor surface, or a ceiling surface are referred to as building materials.

The building material may be damaged due to aging, external force, or the like, and scratches or dirt may occur. Among the building materials, adhesive panels such as P tiles (synthetic resin square sheet materials: plastic tiles) and cushion floors are used for repairs and remodeling. Exposed and new building materials are affixed to the exposed walls and floors. Asbestos (asbestos) is not used for new building materials in order to reduce the environmental load, but building materials containing a certain amount of asbestos are often used for old buildings. If the building material containing asbestos is peeled off, there is a risk that the asbestos crushed from the broken building material will scatter and cause health problems. In addition, when building materials with a low asbestos content are peeled off by force, the building materials are cracked when they are peeled off and dust is scattered with a loud sound, resulting in a heavy load on the worker and poor working conditions.
In addition, for road marking materials among the above building materials, if there is a chance to reform such as changing the position of the markings, the road surface is exposed by exposing or scraping off old building materials attached to the road surface such as concrete or asphalt. New building materials are applied or affixed to the road surface. Road surfaces such as concrete and asphalt are hard and have a lot of minute irregularities on the surface, and the road surface marking material is in close contact with the road surface, so if you do not apply external force mechanically by using a chisel and hammer, etc. It is difficult to remove the (road marking material) itself. When the building material is peeled off with force, the building material is cracked when the building material is peeled off, and dust is scattered with a loud sound, resulting in a heavy load on the worker and poor working conditions.
On outdoor road surfaces such as roads, there is a method of peeling the road marking material by heating the road surface to a high temperature using a firearm such as a burner, but the use of firearms is prohibited by laws and regulations in buildings such as houses and commercial facilities In fact, no good method has been found to peel off road marking materials indoors in a safe manner.

  On the other hand, various efforts have been made to peel off the building material so that dust is not scattered as much as possible, and patent documents 1 to 4 have been published.

  Patent Document 1 describes that in order to heat the building material affixed to the floor surface with an adhesive, a mechanism that uses gas radiation to heat the ceramic plate and utilize the radiant heat from the ceramic plate is mounted on the carriage. Has been. The device described in Patent Document 1 is a system for burning gas, and cannot be used in places where fire is strictly prohibited, and cannot be used when a combustible material such as wood is used as part of the building material.

  Patent Document 2 describes a wedge-shaped tool incorporating an electric heater for heating and peeling a building material affixed to a floor surface with an adhesive. Since the tool described in Patent Document 2 directly heats the building material, the building material may be burnt or burnt.

  In Patent Document 3, it is described that a mechanism for burning a mixed fuel and blowing hot air from a heater is mounted on a carriage in order to heat a building material adhered to a floor surface with an adhesive. The device described in Patent Document 2 is a method for burning a mixed fuel, and cannot be used in a place where fire is strictly prohibited, and cannot be used when a combustible material such as wood is used as a part of building materials. In addition, it is difficult to control the temperature of hot air, and there is a risk that the building material will burn or burn if the hot air is blown directly onto the building material.

  Patent Document 4 describes that an asbestos-containing member is heated and melted to be harmless by locally irradiating the asbestos-containing member with infrared rays from a halogen lamp. Although the asbestos melting method described in Patent Document 4 is disclosed until the asbestos is heated and melted and detoxified by infrared irradiation, the asbestos sprayed and exposed on the concrete is also targeted from the examples. In addition, since infrared rays emitted from a halogen lamp have poor heating efficiency, it is difficult to heat and melt asbestos used inside the building material. Moreover, since patent document 4 is the structure which irradiates infrared rays with a pinpoint, the building material adhere | attached by the predetermined area cannot be peeled off efficiently.

  As described above, in order to peel off the building material so that the dust does not scatter, the building material may be heated and peeled off. However, in Patent Document 1 and Patent Document 3, the fuel is burned, such as a house or a commercial facility. It cannot be used in places where fire is strictly prohibited, such as in buildings, and cannot be used when combustible materials such as wood are used as part of the building materials. In patent document 2 and patent document 3, since the building material is heated directly, there exists a possibility that a building material may burn or burn. And none of patent documents 1-3 is constituted so that the building material stuck on the wall surface may be peeled off. Patent Document 4 targets asbestos sprayed and exposed on concrete, and heating efficiency is low with infrared rays emitted from halogen lamps, so that asbestos used on the inside of building materials is heated and melted. Is difficult, and because it is configured to irradiate infrared rays at a pinpoint, it is not possible to efficiently peel off building materials bonded in a predetermined area.

  Therefore, in view of the above-described problems, the object of the present invention is to provide a road marking material disposed on a predetermined ward screen such as a road surface, a wall surface, a floor surface, or a ceiling surface in a building such as a house or a commercial facility. The building materials such as adhesive panels are heated in an appropriate temperature range for safe and reliable peeling, and even if the building materials contain asbestos in old buildings, fire is used on site. It is another object of the present invention to provide a building material peeling heater and a building material peeling method that perform safe and stable heating without burning the building material.

Since the heater is arranged, the electric heater can be used to maintain a predetermined interval, and by surrounding the electric heater, heat can be heated to a certain degree. That is, without using fire at the site, without burning the building materials, it is possible to perform safe and stable heating, and by efficiently heating the building materials such as road marking materials and adhesive panels without releasing heat, It can be easily peeled off.

  The casing has a box shape, and more specifically, a triangular box, a square box, a polygon box, a round box, a dome box, and the like can be given. Since the section screen is often in the shape of a quadrangle, the casing is preferably in the shape of a square box. By making the casing into a square box shape, it becomes easy to align with the P tile and the like, and it becomes easy to heat and peel the building material to every corner.

  Examples of the electric heater include heaters such as a carbon heater, a ceramic heater, a halogen heater, a nichrome wire heater, and an oil heater. From the viewpoint of heating and melting asbestos to make it harmless, a heater that efficiently emits infrared rays, particularly far infrared rays, is preferable, and a carbon heater and a ceramic heater are particularly preferable. Examples of the shape of the heater include a rod shape, a plate shape, and a block shape. From the viewpoint of reducing power consumption by reducing current consumption, a rod-shaped heater is preferable. The heater operates at AC 100V or AC 200V. Considering use in a general house, a configuration that operates at 100 VAC is preferable because of its high versatility.

  According to the present invention, since the heater is a carbon heater that can efficiently emit far infrared rays, it becomes easy to heat and melt asbestos and make them harmless by radiation of far infrared rays, An object having a high water content such as an agent can be heated particularly efficiently.

The heating temperature of the building material is a temperature that softens the resin constituting the building material and the adhesive layer of the building material. When the heating temperature is less than 80 ° C., the resin constituting the building material and the adhesive layer of the building material are difficult to soften. When the heating temperature exceeds 200 ° C., the building material may be burnt. Therefore, the heating temperature is set to a temperature of 80 ° C. or higher and 200 ° C. or lower. Since the temperature in the casing of the heater (the temperature at a position slightly retracted from the opening surface of the casing) can be regarded as the heating temperature of the building material, the temperature in the casing of the heater is 80 ° C. or more and 200 ° C. or less. Set to For example, by setting the temperature in the casing of the heater to 120 ° C. or higher, the resin constituting the building material or the adhesive layer of the building material can be softened regardless of whether it is an epoxy resin or a urethane resin. It becomes easy. For example, the temperature in the casing of the heater is set to 120 ° C. or higher and 180 ° C. or lower.
If the heater is too close to a road surface, floor surface, or building material within a few millimeters, the possibility of contact with the floor surface or building material increases. In addition, an effective heating effect can be obtained by adopting the configuration of the present application without bringing the heater close to the road surface, floor surface, or building material within a few millimeters. According to the experiment of the present inventor, by using the radiant heat of the electric heater as in the present invention, by surrounding the electric heater and heating it in a state where the heat is confined to some extent, the heater is road surface.

Hereinafter, specific embodiments for carrying out the present invention will be described with reference to the drawings.
In buildings such as houses and commercial facilities, wall surfaces, floor surfaces, ceiling surfaces, and the like are ward screens that divide the room, and various building materials are affixed to the ward screens. The building material in this case is also called a P tile (plastic tile) or a cushion floor, and is attached to a wall surface, a floor surface, a ceiling surface, or the like with an adhesive such as an epoxy adhesive or a urethane adhesive.
Further, in the building, there is a road surface such as an indoor parking lot as a predetermined section screen, and a road marking material among various building materials is applied or pasted on the road surface made of concrete, asphalt or the like.
For example, in the example shown in FIG. 19, a building material 101 such as a P tile is attached to a wall surface 103 of a building via an adhesive 102, and a building material 111 such as a cushion floor is attached to the building via an adhesive 112. Further, a building material 121 such as a panel is attached to the ceiling surface 123 of the building via an adhesive 122.
For example, in the example shown in FIG. 20, a building material 101 such as a road marking material is applied to or pasted on a road surface 133 such as an indoor parking lot.

(First embodiment)
FIG. 1 shows a state in which the building material peeling heater of the first embodiment to which the present invention is applied is brought into contact with the surface of a building material 101 such as a P tile affixed to the wall surface 103 with an adhesive 102 from the side surface side. FIG. The building material 101 is affixed to the wall surface 103 with an adhesive 102 such as an epoxy adhesive or a urethane adhesive.

  The building material peeling heater 1 according to this embodiment includes a box-shaped housing 2 having an opening 2a, a plurality of electric heaters 4 arranged at predetermined intervals in the housing, and a temperature sensor 7 that measures the temperature in the housing. And a controller 6 that controls the temperature of the heater 4 based on a detection signal from the temperature sensor 7 (FIGS. 1 to 5), and operates with a household AC power supply AC100V.

  The casing 2 has a square box shape, and a rectangular frame-shaped metal frame 3 is built in the casing, and a plurality of rod-shaped heaters 4 are bridged on both side surfaces of the metal frame 2 to form a predetermined interval. Installed in. This is because the case 2 has a square box shape, so that it can be easily aligned with a rectangular P tile or the like, and the building material 101 can be easily heated and peeled to every corner. For example, when the size of the housing 2 is a square box shape that is slightly larger than the P tile, the P tiles can be separated one by one. For example, since the section screens and steps of stairs in the floor and many elevators are rectangular, the building material 101 is efficiently heated and peeled to every corner while sliding the casing 2. Can do. Even in a closed place such as in an elevator or a narrow place such as a step of a staircase, the building material 101 is efficiently heated to every corner while sliding the casing 2. And can be peeled off.

  In the example shown in FIG. 2, five heaters 4 are arranged in the metal frame 3. The metal frame 3 is made of stainless steel, iron, aluminum, copper alloy, or the like, and is made lightweight by increasing the rigidity by combining the rectangular cylindrical members. The metal frame 3 is made slightly smaller than the inner surface of the housing 2 to provide a space. This structure is designed so that heat from the metal frame 3 does not leak to the outside of the housing 2 and enhances heat retention and heat insulation. The inner surface of the housing 2 is painted black so that far infrared rays and infrared rays from the heater 4 do not leak outside the housing 2.

  A reflection plate 5 is disposed on the back side of the metal frame 3, and the opening surface 2a, the frame 3, and the reflection plate 5 are arranged in this order (FIGS. 1 and 2). The reflection plate 5 reflects far infrared rays from the heater 4, and the surface thereof is a mirror surface. The reflecting plate 5 is made of glass, stainless steel, iron, aluminum, bronze or the like, and here, a flat plate made of stainless steel is used as the reflecting plate 5.

  In the present embodiment, a rod-like carbon heater 4 is used. This is because the rod-shaped heater 4 is preferable from the viewpoint of reducing current consumption and reducing power consumption. And by using the rod-shaped carbon heater 4, a far infrared ray can be efficiently radiated. By efficiently radiating far-infrared rays with the rod-shaped carbon heater 4, it becomes easy to heat and melt asbestos and render it harmless, and an object having a high water content such as an adhesive can be heated particularly efficiently.

  16 and 17 are side views schematically showing the relationship between the heater 4 and the reflection plate 5 in the building material peeling heater 1 of the present invention. Reference numeral 201 denotes a traveling direction of far infrared rays emitted from the heater 4, traveling straight, and emitted from the opening surface 2 a of the housing 2. The far-infrared ray 201 reaches the building material 101 on the wall surface at a shortest distance in a direction perpendicular to the opening surface 2 a of the housing 2. Reference numeral 202 denotes a traveling direction of far infrared rays emitted from the heater 4, reflected by the reflecting plate 5, and emitted from the opening surface 2 a of the housing 2.

  As shown in FIG. 16, when the reflecting plate 5 is a flat plate, a commercially available flat plate made of stainless steel or the like can be applied, resulting in a simple structure. On the other hand, the path of the far-infrared traveling direction 202 reflected by the reflecting plate 5 and radiated from the opening surface 2a of the housing 2 becomes longer, and the angle in the traveling direction is also the opening surface 2a of the housing 2. The angle is different from the direction perpendicular to the angle, and loss of far-infrared energy occurs.

  Therefore, for example, as shown in FIG. 17, the reflecting plate 5 has a jagged shape and the apex of the jagged equilateral triangle of the reflecting plate 5 is removed immediately behind the heater 4. As a result, the path of the far-infrared traveling direction 202 reflected by the reflecting plate 5 and radiated from the opening surface 2a of the housing 2 can be shortened, and the angle of the traveling direction can also be reduced by the opening of the housing 2. The angle is the same as the direction perpendicular to the surface 2a, and far-infrared energy can be radiated more efficiently. Furthermore, in the above-described embodiment, the reflecting plate 5 is a mirror-like flat plate. However, a configuration may be adopted in which infrared rays are evenly distributed by providing a large number of projections and depressions.

  In the present embodiment, a temperature sensor 7 for measuring the temperature in the housing 2, a heater 4, and a controller 6 for controlling the temperature of the heater 4 are electrically connected. The temperature sensor 7 is a rod-shaped sensor and is disposed at a position between the heater 4 and the heater 4 and is inserted into a through hole penetrating the reflecting plate 5 and the back plate 21 (FIG. 1). The controller 6 is a commercially available product, and is disposed on the back plate 21 of the housing 2 with the operation panel and display facing upward (FIG. 3).

  On the opening surface 2a side of the casing 2, spring-type ball casters 25 are arranged at predetermined intervals (FIG. 2). In the example shown in FIG. 2, spring ball casters 25 are attached to the four corners on the opening surface side of the metal frame 3. According to the present embodiment, when moving on the wall surface or floor surface, it becomes easy to move with the spring ball caster 25, and when bringing the housing 2 into contact with the surface 101a of the building material 101, the spring ball The caster 25 retracts and closes the opening surface 2a of the heater 1 (FIG. 1).

  The heater 4 is arranged at a position which is substantially parallel to the opening surface 2a of the housing 2 and retracted by a predetermined amount. When the housing 2 is brought into contact with the surface 101a of the building material 101, the opening surface 2a is closed and is denoted by S.

(Building material peeling method)
The building material peeling procedure of this invention is demonstrated below.

  FIG. 11 is a diagram showing a conical tool according to the building material peeling method of the present invention. The conical tool 51 includes a conical member 511, left and right blades 512, a mandrel 513, and a handle 514 in this order from the tip side. The cone-shaped tool 51 is formed by thickening the tip of a so-called cone and welding the blades in a V shape to the left and right of the base side of the cone member 511. The building material can be cut off from the wall or floor by the left and right blades 512 while breaking through the building material by the conical member 511.

  As the building material peeling procedure of the present invention, first, the above-described building material peeling heater 1 is used, the power cord is inserted into the household AC power supply AC100V, and the power switch is turned on (not shown). And the housing | casing 2 of the heater 1 is made to contact | abut to the surface 101a of the building material 101 stuck on the wall surface, the opening surface 2a of the heater 1 is made into the closed state, and it heats (FIG. 1, FIG. 12). For example, if five 20 W heaters are used as the heater 4, the rating of the heater 1 is about 100 W.

  The heating temperature of the building material 101 is a temperature that softens the adhesive layer 102 of the building material 101, and the heating temperature is 80 ° C. or more and 200 ° C. or less. When the heating temperature is less than 80 ° C., the adhesive layer 102 of the building material 101 is not softened. If the heating temperature exceeds 200 ° C., the building material 101 may be burnt. Here, since the temperature in the housing 2 of the heater 1 can be regarded as the heating temperature of the surface 101 a of the building material 101, the temperature in the housing 2 is set to 80 ° C. or more and 200 ° C. or less by the controller 6. In order for the adhesive layer 102 of the building material 101 to be easily softened, whether it is an epoxy adhesive or a urethane adhesive, the temperature in the housing 2 is set to 120 ° C. or higher and 180 ° C. or lower. For example, when the heating temperature is 120 ° C. for 5 minutes to 10 minutes, the building material 101 can be peeled off. For example, when the heating temperature is 180 ° C. for 2 minutes to 5 minutes, the building material 101 can be peeled off.

  After the heating, the heated area of the building material 101 is peeled off with a predetermined tool (FIG. 13). In the present embodiment, the heated area of the building material 101 is pierced by the conical member 511 at the tip of the conical tool 51 to form the grooves 151 at a predetermined interval W1. More specifically, the predetermined interval W1 is 2 cm to 10 cm. In consideration of workability, the predetermined interval W1 is preferably the same as the width of the cutter 52, and preferably 3 cm to 6 cm. The conical tool 51 may be a commercially available cone.

  After forming the groove 151 at the predetermined interval W1, the cutting edge 521 of the cutter 52 is cut into the adhesive layer 102 on the back surface side of the building material 101 and cut in the state of the belt-like building material 1101 (FIG. 14). The cutter 52 may be a commercially available flat cutter, or may be appropriately modified so that the approach angle becomes an appropriate angle by screwing the blade edge of the flat cutter to the chisel. FIG. 15 is a diagram showing the wall surface 103 peeled off by the building material peeling method. According to this embodiment, it becomes easy to reliably peel off the building material 101 using a simple tool without applying much force. In addition, when the adhesive agent 102 has adhered to the exposed wall surface 103, the wall surface 103 is again heated with the heater 1, and it can cut off with the cutter 52, and the adhesive agent 102 can be almost removed. .

  According to the building material peeling method of the present embodiment described above, even if it is a building material 101 containing asbestos in an old building or the like, the building material is not broken and dust is not scattered when peeling off. Even if it does not use an apparatus, by using the heating machine 1 of this embodiment, an operator can perform the safe and stable heating, and can peel the building material 101. And since the building material 101 can be reliably peeled off without applying too much force, the load on the worker is small and the working conditions are greatly improved. In the building material peeling method of the above-described embodiment, the example has been described in which the building material 101 affixed to the wall surface 103 is peeled off. However, when the building material 111 affixed to the floor surface 113 with the adhesive 112 is heated and peeled off from the surface 111a. The same excellent effect is exhibited when used. Moreover, the same excellent effect is exhibited also when using the building material 121 affixed to the ceiling surface 123 with the adhesive 122, when heating and peeling from the surface 121a. Needless to say, the building materials (101, 111, 121) attached to the flat surface as well as the wall surface, floor surface, and ceiling surface can be peeled off.

That is, the temperature rise time of the heating by the heater 4 can be shortened by blowing hot air from the small holes 38 provided at predetermined intervals on the inner side surface of the metal frame 3. Since the hot air blown out from the small hole 38 is not directly blown onto the surface 101a of the building material 101, there is no possibility that the building material 101 will burn. The hot air fan 39 may be small, and the temperature of the hot air is set to 80 ° C. or higher and 200 ° C. or lower. In the example shown in FIG. 9, the heaters 4 and the hot air blowing small holes 38 are alternately provided. However, for example, the upper half side may be the hot air blowing small holes 38 and the lower half side may be the heater 4. By this, it becomes the structure which heats in the lower half side, preheating in the upper half side, and since it can be used to peel off the building material 101 while moving the heater 1 little by little, two workers form one worker. Can be heated, and the other worker can peel it off.

In the present embodiment, when the blower fan 281 is operated, the air in the space between the back cover 39 and the reflecting plate 5 is blown as hot air or hot air, reaches the duct pipe 282, and enters the duct pipe 282. Thus, the flow path 28 is formed by changing the traveling direction and blowing out from the vent hole 283 toward the opening surface 2a of the housing 2 (FIGS. 21, 25, and 26). A dotted line arrow 28a in FIG. 26 indicates the flow of air.

  According to the present embodiment, since the reflecting plate 5 and the back cover 39 have a double structure, it is easy to suppress heat generation from the back side of the housing 2, and when the air blowing means 281 is operated, Since the air in the space between the cover 39 and the reflecting plate 5 (dotted line arrow 28a in FIG. 26) blows out from the vent hole 283, a flow path toward the opening surface 2a of the housing 2 is formed. The heat from the back side of the plate 5 is effectively used to heat the building material 131 in the direction of the opening surface 2a of the housing 2 as warm air or hot air.

  In the example shown in FIG. 25, three ventilation holes 283 are formed in the lower left side of the side surface of the frame 3, and warm air is effectively directed toward the building material 131 by the ventilation holes 283 provided at predetermined positions. . The warm air blown out from the vent hole 283 escapes from the gap between the opening surface 2a of the housing 2 and the building material 131. As a configuration other than the above configuration, for example, a plurality of ventilation holes may be provided at a predetermined interval on the lower side of the side surface of the frame 3.
