DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below.

As shown in FIG. 2, the bonding material A for building of this embodiment is a material obtained by mixing a conductive material such as carbon in a synthetic resin, and is formed on a conductive resin sheet 1 having a planar heater function. It is configured. The conductive resin sheet 1 is
By applying an overvoltage to the carbon, the carbon generates heat to melt the synthetic resin, and is heated and welded to the base material to be joined. Note that a conductive material other than carbon may be used. The synthetic resin serving as the base material is not particularly limited, and a resin that is melted by the heat generated by carbon is used. Reference numeral 8b in FIG. 1A denotes a lead wire drawn from the electrode 8a, and is connected to, for example, a DC12V battery.

In this embodiment, the eaves gutter 4 and the gutter joint 5 are illustrated as the substrates to be joined. End 4 in the longitudinal direction of adjacent eaves gutter 4
are connected by a gutter joint 5, and the conductive resin sheet 1 is interposed between the gutter joint 5 and the eaves gutter 4. The gutter joint 5 is formed to have a substantially C-shaped cross section with an open upper surface, and an inner periphery formed along the outer surface of the eaves gutter 4. 7 are provided. On the other hand, the eaves gutter 4 is formed in a substantially C-shaped cross section with an open upper surface, and the upper end on the indoor side and the upper end on the outdoor side are ears 6, respectively. When the conductive resin sheet 1 is brought into contact with the inner surface of the gutter joint 5, the conductive resin sheet 1
Both ends in the length direction extend to the vicinity of the lug fitting portion 7 of the gutter joint 5, and both sides of the conductive resin sheet 1 can overlap the ends 4 a of the eaves gutter 4 on both sides adjacent to each other. In addition, the size of the conductive resin sheet 1 is set. Thereby, the connecting portion between the adjacent eaves gutter 4 and the gutter joint 5 can be joined using one conductive resin sheet 1. In addition, two conductive resin sheets 1 are arranged on both sides of the inner peripheral surface of the gutter joint 5, one conductive resin sheet 1 is welded to one adjacent gutter joint 4, and the other conductive resin sheet 1 is welded. May be welded to the other gutter 4. The material of the eaves gutter 4 and the gutter joint 5 is, for example, PVC, PP,
It may be a synthetic resin material such as an engineering plastic or a metal material.

Thus, as shown in FIG. 1A, the conductive resin sheet 1 is brought into contact with the inner surface of the gutter joint 5, and the gutter joint 5 is put on the outer surface of the end 4a of the adjacent eave gutter 4, FIG. 1 (b)
Between the gutter joint 5 and the eaves gutter 4 as shown in FIG.
In a state of being pinched. Then, DC1 is connected to the lead wire 8b.
When a 2V battery is connected and an electric current is passed through the carbon to generate carbon, the synthetic resin is melted, and the conductive resin sheet 1 is heat-welded to the eaves gutter 4 and the gutter joint 5, respectively. The connecting portion with the gutter 4 can be joined in a completely adhered state via the conductive resin sheet 1.
Since it is only necessary to energize the conductive resin sheet 1 in this manner, the workability is extremely improved as compared with the conventional method of fitting the gutter joint to the eaves gutter, and the work speed can be increased. it can. In addition, even if there is a molding distortion or a dimensional error between the gutter joint 5 and the eaves gutter 4, the conductive resin sheet 1 melts and the gap between the eaves gutter 4 and the gutter joint 5 is completely closed, so that water leakage occurs. It can eliminate the danger of.

Further, since the conductive resin sheet 1 is made of a synthetic resin in which a conductive material such as carbon is mixed, the conductive resin sheet 1 has a planar heater function with a uniform heat generation temperature. There are advantages. In other words, in the case of the nichrome wire, the temperature becomes high near the nichrome wire, and the temperature becomes extremely low as the distance increases. However, in the case of the conductive resin sheet 1 having a planar heater function of the present invention, the temperature becomes uniform. In addition, there is no bias in joining, and the joining performance is extremely improved. Further, since the applied voltage is determined by the distance between the electrodes 8a, it is not necessary to change the applied voltage even if the area of the conductive resin sheet 1 is changed. Therefore, there is also an advantage that the applied voltage can be kept constant and the controller can be simplified.

FIGS. 3 to 5 show another embodiment of the building jointing material A. FIG. The bonding material A for building of this example is composed of a heater embedded sheet 2 in which a heater 3 is embedded in a soft synthetic resin. In the example shown in FIG. 3, for example, two sheets of soft vinyl chloride 10 are used as the soft synthetic resin, and the heater 3 is arranged between the two pieces of soft vinyl chloride 10 in a sandwich and meandering manner. . Both ends of the heater 3 are welded to the lead wire 9 by spot welding or the like. For example, a cord 30 of a DC12V battery is connected to the lead wire 9. Therefore, as shown in FIG. 4, when the heater buried sheet 2 is interposed between the gutter joint 5 and the eaves gutter 4 and an electric current is applied to the heater 3, the heater 3 generates heat and the soft vinyl chloride 10 is melted. And the eaves gutter 4 can be joined via the heater buried sheet 2. Moreover, since the heater 3 is embedded in a soft synthetic resin such as the soft vinyl chloride 10, 10, the soft synthetic resin is melted by heating the heater 3 for a short time, so that the time required for heat welding can be reduced. At the same time, it helps to save power.

6 to 8 show still another embodiment. Here, FIG. 6A shows release paper 11 on the joining surface of joining material A for building.
(B) is a perspective view when the release paper 11 is peeled off, and (c) is a plan view in a state where the bonding material A for construction is temporarily attached to the inner surface of the butted part of the eaves gutter 4. FIG. 7 shows a joining process of the eaves gutter 4 using the joining material A for building, FIG. 8A shows a perspective view after the eaves gutter 4 is joined, and FIG. 8B shows a rear view.

In this embodiment, a gutter joint is not used, but the ends 4a in the longitudinal direction of the eaves gutter 4 are abutted with each other, and are fused and integrated with the building joining material A. This building bonding material A
The conductive resin sheet 1 shown in FIG.
Any of the heater embedded sheets 2 shown in FIG.
In addition, as shown in FIG. 6, one in which one side of the bonding material for building A is used as a bonding surface, and a release paper 11 is adhered thereon.

At the time of construction, the ends 4a of the eaves gutter 4 are butted together as shown in FIG.
As shown in (b), the release paper 11 of the bonding material A for building (the conductive resin sheet 1 or the heater embedded sheet 2) is peeled off and attached to the inner surface of the butt portion a. Then, by energizing the carbon or the heater to melt the synthetic resin, the end 4a of the eaves gutter 4 is heated and welded via the bonding material A for building as shown in FIG. Therefore, gutter joints become unnecessary,
The number of parts is reduced, the workability is improved, and the risk of water leakage is eliminated by welding the building jointing material A to the inner surface of the butted portion A. In addition, since there is no gutter joint or the like on the outer surface of the abutting part of the eaves gutter 4, FIG.
As shown in (b), a clean appearance is obtained.
Furthermore, since the joining function is previously provided on one side of the joining material A for building, the joining material A for building can be positioned with respect to the eaves gutter 4, and then the joining material A for building is securely attached to the eaves gutter 4 by applying electricity. There is also an advantage that heat welding can be performed.

9 to 12 show still another embodiment of the bonding material A for building. The bonding material for construction A of this example is composed of a perforated conductive plate 21 that is in contact with the inner surface of the butting part a of the eaves gutter 4 that is the building material B, and a surface of the perforated conductive plate 21 on the eaves gutter 4 side. And a resin plate 23 laminated on the opposite surface 21a.

The perforated conductive plate 21 functions as a planar heater, and a hole portion 22 composed of a plurality of small holes is perforated over substantially the entire surface of the conductive plate 21. The holes 22 are used for welding a part of the melted resin to the building material B through the perforated conductive plate 21 when the resin plate 23 is heated and melted by energizing the perforated conductive plate 21. Things.

In this example, the eaves gutter 4 is illustrated as the building material B as the base material to be bonded. The eaves gutter 4 has a three-layer structure in which a core material 25 made of a metal plate or the like is inserted between the synthetic resin material 24 of the inner layer and the synthetic resin material 24 of the outer layer. The core material 25 can be omitted, and it is sufficient that at least the inner surface of the eaves gutter 4 is a synthetic resin material 24.

The perforated conductive plate 21 is formed in the shape of a substantially C-shaped strip which can contact along the inner surface of the abutting portion A of the eaves gutter 4, and has two ends in the circumferential direction. An ear fitting portion 7a that fits into the ear portion 6 of the eaves gutter 4 is provided.

The resin plate 23 is made of, for example, a hot-melt resin, and is formed into a substantially C-shaped strip that can contact along the inner surface of the perforated conductive plate 21. At both ends in the direction, ear fitting portions 7b fitted to the ear fitting portions 7a of the perforated conductive plate 21 are provided. The thickness of the resin plate 23 is, for example, 0.3 to 0.5 m.
m.

Then, the ends 4a of the eaves gutter 4 in the longitudinal direction are abutted with each other, and the perforated conductive plate 21 is brought into contact with the inner surface of the abutting portion b.
The ear fitting portions 7a at both ends of the eaves 1 are fitted to the ear portions 6 of the eaves gutter 4. As a result, the perforated conductive plate 21 is temporarily fixed to the inner surface of the butting portion A of the eaves gutter 4. Further, the resin plate 23 is brought into contact with the inner surface of the perforated conductive plate 21, and the ear fitting portions 7 b at both ends of the resin plate 23 are fitted into the ear fitting portions 7 a of the perforated conductive plate 21. Thereby, the eaves gutter 4
And the perforated conductive plate 21 and the resin plate 23 are in close contact with each other. In this state, when a voltage is applied by connecting the lead wires 20 from, for example, a DC12V battery to both ends of the perforated conductive plate 21, the perforated conductive plate 21 is energized and heated to melt the resin plate 23. The contact surfaces of the resin plate 23 and the perforated conductive plate 21 are welded to each other by the melted resin, and a part of the melted resin is further removed as shown by an arrow C in FIG. It flows down inside and is welded to the surface of the eaves gutter 4.

Here, the inner surface of the eaves gutter 4 is made of a synthetic resin material 2
4, the synthetic resin material 24 forming the inner surface of the eaves gutter 4 is also melted by heating the perforated conductive plate 21, and the molten resin causes the resin plate 23 and the perforated conductive plate 21 to melt. The contact surfaces with the plate 21 are welded to each other,
Further, a part of the molten resin of the resin plate 23 enters the hole 22 of the perforated conductive plate 21, and the molten resin and the molten resin of the synthetic resin material 24 forming the inner surface of the eaves gutter 4 are interposed between the resin. Bonding melts and integrates, thereby increasing bonding strength. Moreover, since the core member 25 made of a metal plate is interposed inside the eaves gutter 4 made of the synthetic resin material 24, the shape of the eaves gutter 4 is deformed even if the synthetic resin material 24 on the inner surface of the eaves gutter 4 is melted. In addition, since the perforated conductive plate 21 and the metal plate forming the core material 25 of the eaves gutter 4 are insulated by the synthetic resin material 24 on the inner surface of the eaves gutter 4, the perforated conductive plate 21 There is no danger of leakage to the metal plate constituting the core material 25 when the voltage is applied. When the core material 25 is not contained in the eaves gutter 4, the melting point of the resin plate 23 is set to a value lower than that of the synthetic resin material 2 forming the eaves gutter 4 in order to prevent the synthetic resin material 24 from being melted.
Preferably, the melting point is lower than 4. In this case, if the heating temperature of the perforated conductive plate 21 is set to be equal to or higher than the melting point of the resin plate 23 and equal to or lower than the melting point of the synthetic resin material 24 forming the eaves gutter 4, the eaves gutter is heated when the perforated conductive plate 21 is heated. The synthetic resin material 24 constituting the eaves gutter 4 is not melted, but only the resin plate 23 is melted, so that the synthetic resin material 24 constituting the eaves gutter 4 can be prevented from being deformed.

As described above, the perforated conductive plate 21 and the resin plate 2 are formed on the inner surface of the abutting portion A of the eaves gutter 4 to be joined.
3 is laminated, and a perforated conductive plate 2 is laminated.
By simply energizing 1, the eaves gutters 4 can be easily and reliably joined together, and the gutter joint 5 (FIG. 1) becomes unnecessary, so that the workability is improved and the work speed can be increased. At the same time, even if the eaves gutter 4 has a distortion or a dimensional error, the resin plate 23 melts and the gap between the eaves gutters 4 is securely closed, thereby causing a risk of water leakage due to the distortion or the like. In addition, since the perforated conductive plate 21 serving as a heater is covered by the resin plate 23, the perforated conductive plate 21 is not exposed to the outside, there is no generation of rust, and the joining function of the eaves gutter 4 is prevented. Can be maintained for a long period of time.

The perforated conductive plate 21 and the resin plate 2
By arranging 3 on the inner surface of the abutting part 4 of the eaves gutter 4, no irregularities are formed on the outer surface of the abutting part A of the eaves gutter 4.
The joining strength between adjacent eaves gutters 4 can be improved. In addition, the perforated conductive plate 21 is laminated on the butting portion a of the eaves gutter 4 and the resin plate 23 is further laminated thereon. It is reinforced by the bonding material A for building composed of the plate 23, and can be prevented from being deformed when an external force is applied to the abutting portion A. In addition, the bonding material A for building in this example has a perforated conductive material. Since the plate 21 is welded and integrated with the inner surface of the eaves gutter 4 by the electric heating to the plate 21, the strength of the eaves gutter 4 is further increased, and as a result, the joining strength of the abutting portion A can be further improved.

When the conductive plate 21 does not have the holes 22, the synthetic resin material having good bonding properties with the conductive plate 21 must be selected as the material of the resin plate 23 bonded to the outer surface of the conductive plate 21. In addition, as the material of the eaves gutter 4 joined to the back surface of the conductive plate 21, a synthetic resin material having good bonding properties with the conductive plate 21 must be selected, and it is necessary to select a synthetic resin material. By providing the holes 22 provided in the conductive plate 21 as described above, the resin plate 23 and the eaves gutter 4 made of the synthetic resin material 24 are melted and integrated by the inter-resin bonding through the holes 22. Synthetic resin materials having a property of bonding to each other may be used as the material of the resin plate 23 and the eaves gutter 4, regardless of the material of the conductive plate 21.
Since the joint 3 and the eaves gutter 4 can be joined, there is an advantage that the selection range of the synthetic resin material is widened.

On the other hand, even when the material of the eaves gutter 4 is a non-synthetic resin material, the resin plate 23 is melted by the electric heating of the perforated conductive plate 21, and a part of the molten resin becomes a perforated conductive plate. It flows down into the hole 22 of the pipe 21 and is welded to the surface of the eaves gutter 4. At this time, by selecting a material having a good bonding property with the molten resin of the resin plate 23 as the material of the eaves gutter 4, the bonding strength between the eaves gutter 4 made of non-synthetic resin and the resin plate 23 can be increased.

FIGS. 13 and 14 show another embodiment. In the present example, the ends 4a of the eaves gutter 4 orthogonal to each other in the longitudinal direction are connected via a bending member 50, and the bending members 5 are connected.
0 shows a case where both ends 50a of the eaves 0 and the ends 4a in the length direction of the eaves gutter 4 are joined by heat welding using a joining material for construction. The bending member 50 of the present example is bent at a substantially right angle when viewed from a plane, and both end portions 50a are formed to have the same shape as the shape of the longitudinal end portion 4a of the eaves gutter 4, and the bending member is bent. On both sides in the width direction of 50, ear locking portions 51 for locking the ears 6 of the eaves gutter 4 are provided, respectively. Further, as the bonding material A for building, FIGS.
The heater-embedded sheet 2 shown in FIG. 5 is used, but is not limited to this. Of course, the carbon-containing conductive resin sheet 1 shown in FIGS.
The laminated structure of the perforated conductive plate 21 and the resin plate 23 shown in FIG.

Thus, both ends 50a of the bending member 50
The heater-embedded sheet 2 is set on the upper surface, and the longitudinal end 4a of the gutter 4 is pushed into the inside of the bending member 50 from above, so that the heater-embedded sheet 2 is connected to the end 4a of the gutter 4 and the bending member 50. While being sandwiched between the end portions 50 a, the ear portions 6 on both sides of the gutter 4 are respectively locked by the ear locking portions 51 of the bending member 50. In this state, when a current is passed through the heater, the heater of the heater-embedded sheet 2 generates heat to melt the soft vinyl chloride, and the end 50a of the bending member 50 and the end 4a of the gutter 4 are easily and reliably welded by heat welding. Be able to join. As a result, the joining operation is extremely easy as compared with the case where the conventional adhesive or the like is used, and furthermore, it is possible to surely prevent rain leakage due to variation in application such as the adhesive and deterioration over time, Furthermore, since the bending member 50 and the eaves gutter 4 can be joined without any gap by heat welding, it is possible to prevent rain leakage and improve the appearance of the eaves gutter 4 in bending.

FIGS. 15 and 16 show still another embodiment. In this example, the stop member 60 is arranged at the longitudinal end 4a of the eaves gutter 4, and the end 60a of the stop member 60 and the end 4a of the eaves gutter 4 are embedded with the heater similarly to FIGS. A case where the sheet 2 is joined by heat welding is shown. A gutter mounting portion 61 having the same shape as the lengthwise end 4a of the eaves gutter 4 protrudes from the end portion 60a of the stop member 60 along the lower edge thereof. On both sides in the width direction of the portion 61, ear locking portions 62 for locking the ears 6 of the eaves gutter 4 are provided. This gutter mounting part 61
The heater-embedded sheet 2 is set on the upper surface, and the longitudinal end 4a of the gutter 4 is placed thereon, and the heater-embedded sheet 2 is moved to the end 4a of the gutter 4 and the gutter placing portion of the stop member 60. 61
And the ears 6 on both sides of the gutter 4 are respectively engaged with the ear engaging portions 62 of the stop member 60. In this state, the heater is heated by energizing the heater-embedded sheet 2. The soft vinyl chloride is melted, and the end 60a of the stop member 60 and the end 4a of the gutter 4 can be easily and reliably joined via the heater buried sheet 2, thereby preventing rain leakage and improving the appearance at the stop. Can be done.

The materials of the eaves gutter 4, the bending member 50, and the stop member 60 are not particularly limited, and are widely applied to, for example, vinyl chloride, PP, engineering plastics, and the like.

In the above embodiments, the joining of the eaves gutters 4 has been described, but the joining material A for construction of the present invention can also be used for the joining of the eaves gutters or the joining of the eaves gutters and the downspouts. Needless to say, the bonding material for construction A of the present invention can also be effectively used for bonding various building materials other than gutters.
