Description

  The present invention relates to an eaves bracket and an eaves device, and more specifically, a heater that can easily and inexpensively attach a belt heater that can efficiently melt snow and ice in an eaves bracket body. The present invention relates to an eaves bracket provided with an attachment member, and an eaves apparatus using the eaves bracket so that a belt-like heater is stably fixed in the eaves.

  In cold snowy areas, there is a risk of snow entering the eaves and if the water is left as it is, the melted water will freeze, the eaves may be destroyed by the weight of snow or ice, and the icicles hanging on the eaves may fall and cause personal injury. There is.

  For this reason, the present applicant proposes to improve the eaves ridge structure as shown in FIG. 4 to cover the opening on the upper surface side of the eaves ridge main body 3 and to provide the fluid guide 6 so as to serve also as the roof tip member. (See Patent Document 1). And since the cross section of the curved surface part of the fluid guiding fluid 6 is substantially U-shaped or semicircular, and placed sideways, the snow that has fallen or slipped down on the fluid guiding fluid 6 accumulates in the cage. It came to slide down on the ground without any problems. However, no heater is installed and the snow and ice inside the eaves cannot be melted.

In heavy snowy areas, an anti-icing device may be installed on the roof, but since it costs a lot of money, a means for preventing snow melting and icing that can be easily installed on the eaves is desired.
In response to such a request, in Patent Document 2, as shown in FIG. 5, the cross-sectional area of the eaves ridge 4 is reduced to about one third of the eave ridge of a normal size. The amount of snow and ice that accumulates in the eaves wall is tilted with respect to the eaves board so that a level difference of 7 will occur between the upper edge of the mounting side and the upper edge on the opposite side. It has been proposed to reduce. An electric heater 5 is provided at the bottom of the eaves to prevent the melted water of the eaves from freezing.
However, in Patent Document 2, since the electric heater 5 is mounted so as to crawl the bottom wall of the eaves 4, the snow and ice around the heater 5 melt, but the snow and ice above it still remain. It does not lead to fundamental problem solving.

On the other hand, in Patent Document 3, as shown in FIG. 6, a rain gutter attached so that the entire surface of a sheet-like electrothermal carbon heater 5 is inclined in the gutter 4 and many heaters 5 can be connected in the longitudinal direction. Snow melting devices have been proposed.
In this way, by stretching the heater 5 diagonally across the interior space of the eaves 4, the amount of snow and ice that melts is greater than in the case of Patent Document 2, but it takes time and money to install it in the eaves. In addition to being exposed to light, there is a problem that the heater is likely to deteriorate because the area exposed to sunlight is large.

  Under such circumstances, there is a need for an eaves bracket that can easily fix the heater in the eaves without reducing the amount of snow melted by the heater in the eaves interior space and without labor and cost.

  In view of the problems of the prior art, an object of the present invention is to provide a heater attachment member that can easily and inexpensively attach a belt-like heater that can efficiently melt snow and ice in an eaves cage below the eaves cage bracket body. It is an object of the present invention to provide an eaves bracket provided and an eaves device using the eaves bracket so that a belt heater is stably fixed in the eaves.

  In order to solve the above problems, the present inventor has conducted extensive research and developed a new eaves bracket with a heater mounting member attached to the eaves bracket. The heater mounting member surrounds the lower and side surfaces of the belt-like heater. It was designed to be combined with the eaves bracket body. As a result, the side surface of the belt-like heater is fixed in an upright state at the substantially central portion of the eaves so that the belt-like heater is less likely to swing in the eaves so that a sufficiently large snow melting ability can be secured.

  That is, according to the first aspect of the present invention, there is provided an eaves bracket, wherein the eaves bracket bracket body is provided with a heater mounting member that enables a belt-like heater to be installed therebelow.

According to a second aspect of the present invention, in the first aspect, the heater mounting member supports the side surface of the belt-shaped heater so as to be in an upright state in the eaves. An eaves bracket is provided.
Furthermore, according to the third invention of the present invention, in the first or second invention, the eaves comprising the eaves bracket, a belt heater attached to the eaves bracket, and the eaves supported by the bracket. A dredge device is provided.

  According to the eaves bracket according to the present invention, since the heater mounting member is attached to the eaves bracket body, the heater can be easily fixed to the eaves bracket after the strip heater is inserted into the eaves bracket. In addition, the manufacturing cost is low, the efficiency of the installation work is increased, and there is an advantage that it can be easily attached to an existing ordinary eaves.

  Further, according to the present invention, since the belt-like heater is fixed upright to the substantially central portion of the eaves by the heater mounting member, the side area of the heater that comes into contact with snow or ice is increased, and the thermal efficiency is good. Furthermore, since the heater does not block the flow of rainwater and the area exposed to sunlight is kept small, the heater is unlikely to deteriorate.

It is a side view which shows the state which made the heater stand upright in the approximate center part of the eaves wall, and was fixed in the eaves wall by this invention. It is front sectional drawing which shows the state which fixes a heater to an eaves bracket by this invention. It is a top view which shows the state which fixes a heater to an eaves bracket by this invention. It is sectional drawing of the prior art which shows the external appearance of the eaves structure in a snowy area. It is sectional drawing which shows the external appearance of the eaves structure in the snowy area which is another prior art. It is sectional drawing of the prior art which shows the external appearance of the structure which attached the heater diagonally to the eaves.

  Hereinafter, the eaves bracket and the eaves apparatus according to the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall side view of an eaves bracket according to the present invention and a state in which the heater is fixed upright in the eaves using the eaves bracket, and FIG. 2 is a front sectional view thereof. FIG. 3 is a plan view thereof.

  The eaves bracket (hereinafter also simply referred to as a bracket) of the present invention is characterized in that, in FIG. 1, the eaves bracket bracket body 3 is provided with heater mounting members 51 and 52 that allow the belt-like heater 5 to be installed therebelow. It is said.

  The eaves bracket 3 is a member for suspending the eaves cage 4 and connecting it to a house structure such as the eaves nose cover plate 2. The eaves bracket 3 generally includes an eaves bracket bracket tip 311 that grips the front ear 43 of the eaves, a rear end 312 of the eaves bracket that grips the rear ear 44 of the eaves, and a support portion 32 that connects them. A member having a function of a mounting plate 33 for lifting and fixing the eaves hook to the eaves nose cover plate 2 is provided. In the present invention, heater mounting members 51 and 52 are further provided.

In addition, the overall shape of the eaves bracket 3 is not particularly limited. However, since the heater mounting member 52 is attached to the upper surface or the lower surface, the shape of the upper surface is flat and wide at the intermediate portion as shown in FIG. It is desirable.
The eaves bracket 3 may be made of plastic, but metal is preferable. This is because a heavy heater must be supported.

In the present invention, the heater mounting member 52 is a member for fixing the upper end of the heater mounting member 51 to the eaves bracket 3 and is a metal piece having at least two holes. FIG. 2A illustrates a member having an inverted L shape. The at least two holes of the heater mounting member 52 are for inserting the tip of the heater mounting member 51. Two holes for inserting the tips of the heater mounting members 51 are located outside the bracket side end portions. Then, as shown in FIG. 3, there is another hole at the other end, which is attached with a screw or the like so as not to be detached from the bracket.
If the structure of the other end of the heater mounting member 52 is clipped as shown in FIG. 2 (B), it can be mounted simply by sandwiching the upper surface of the bracket without providing a hole for fixing to the bracket 3. It becomes easier.

  In the present invention, heater mounting members 51 and 52 are attached to the eave ridge bracket body in order to fix the belt-like heater 5 (hereinafter, also simply referred to as a heater) upright at the substantially central portion of the eave ridge and fix it in the eave ridge. ing.

  The heater mounting member 51 is one size larger than the belt-like heater 5 and is not limited by the shape as long as it can surround the lower surface and side surfaces thereof. For example, as shown in FIG. A so-called U-bolt machined by threading may be mentioned. Although the thickness of a volt | bolt is suitably determined according to the size and weight of a heater, 1-5 mm is preferable, for example.

  Examples of the heater mounting member 51 include a string-like body in which the periphery of a wire is encapsulated (coated) with a resin, which is used to bundle electric appliance cords in addition to U-bolts. This string-like body is called a vinyl tie (a vinyl string containing a thin wire). The type of resin is preferably one having high heat resistance. The thickness of the wire is appropriately determined according to the size and weight of the heater, but is preferably 0.5 to 3 mm, for example. The width of the resin including the wire is, for example, 0.8 mm to 10 mm, and may be a constant width. However, if the width of the intermediate portion is widened so that the area of the portion in contact with the lower surface of the heater can be increased, the resin can be suspended more stably. be able to.

  The length (height) of the heater attachment member 51 is larger than the vertical width of the heater, and when the heater is attached, it is necessary to extend from the vicinity of the bottom of the eaves to the upper part of the bracket. This is to prevent the bottom portion of the heater from coming into contact with the bottom portion of the ridge and to stably fix the heater at the substantially central portion of the ridge.

Next, the eaves apparatus of the present invention will be described. The eaves apparatus of the present invention comprises the eaves bracket described above, a belt heater attached to the eaves bracket, and the eaves supported by the bracket.
The belt-like heater used in the present invention is not limited by a heating method as long as it can be installed in an eaves and can melt ice water and snow. For example, a self-temperature control heater (PTC heating element heater), a sheathed heater, etc. Is exemplified.

  The self-temperature control type heater is one in which electric wires serving as a pair of electrodes are provided in a PTC heating element layer. Since the electric current flows through the PTC heating element layer, the electric wires that form a pair of electrodes are arranged apart from each other in the PTC heating element layer. The outer peripheral surface of the PTC heating element layer is covered with an electrically insulating coating material layer so that the current from the PTC heating element layer does not leak into rain water, snow, ice or the like in the eaves.

In the PTC heating element layer, ceramics having PTC characteristics (ceramics having a positive resistance temperature coefficient) such as barium titanate ceramics and vanadium oxide ceramics, and carbon black having PTC characteristics are dispersed in a binder material. The exothermic composition is made.
As this binder material, for example, high pressure method low density polyethylene, low pressure method linear low density polyethylene, ultra high molecular weight polyethylene, EVA, EEA, silicone rubber, nitrile rubber, fluorine rubber, fluorinated ethylene propylene resin, etc. are used. As the electrical insulation coating material, thermoplastic resins such as high pressure method low density polyethylene, linear low density polyethylene, high density polyethylene, and thermoplastic polyolefin elastomer are used. A material using ceramics such as alumina having excellent electrical insulation, heat resistance, mechanical strength, and thermal conductivity may be used as the electrical insulation coating material. Moreover, as an electric wire, a copper wire, an aluminum wire, a copper foil, an aluminum foil or the like is used.
This self-temperature control type heater does not require a temperature control circuit for keeping the heat generation temperature constant or an overheat prevention circuit for preventing overheating, and has extremely high safety.

On the other hand, the sheathed heater is a nichrome wire with a heating element provided with a terminal. Around the nichrome wire is filled with an electrical insulating material such as magnesia powder, alumina powder, silica powder, silicone oil, etc. to prevent leakage of current from the nichrome wire, and outside the electrical insulating material layer is a metal A protective tube such as a tube, a glass tube, or a plastic tube is provided. In addition, an insulating partition plate is provided so that the nichrome wires do not come into contact with each other to cause a short circuit.
Unlike the self-temperature control type heater, the sheathed heater needs to be provided with a temperature control circuit for keeping the heat generation temperature constant and an overheat prevention circuit for preventing overheating. The sheathed heater is preferable in the present invention because it is relatively inexpensive and easily available.

The dimensions of the belt heater may be, for example, 1-5 cm in length, 0.5-3 cm in width (thickness) and 4-10 m in length, 1-3 cm in length, and 0.5-2 cm in width (thickness). And the length is preferably 5 to 8 m. This is because it is easy to put the heater in the fence, and because the area that comes into contact with snow and ice is large, the heat efficiency is good, and the heater is difficult to block the flow of rainwater in the eaves. That is, in the present invention, it is preferable that the heater has a belt-like cross-sectional shape, but the heater is also thick and relatively short so that it can be seen as a rod.
Generally speaking, the sheathed heater is often cylindrical (having a circular cross section), but in the present invention, it is desirable to use a flat shape (a rectangular oblong cross section). For example, the trade name “Super Flat Heater” commercially available from Shin-Heat Industry Co., Ltd. can be mentioned.

  In order to fabricate the eaves apparatus of the present invention, as shown in FIG. 1, a belt-like heater 5 and heater mounting members 51 and 52 for fixing it in the eaves are prepared. Assemble.

  Then, the heater mounting member 52 is placed on the upper surface of the bracket, and as shown in FIG. 2A, the end of the inverted L-shaped member is mounted to the hole of the support portion 32 on the upper surface of the bracket with a screw. At this time, the direction of the member 52 may be reversed, and the end portion may be attached to the support portion 32 on the lower surface of the bracket with a screw. As for the position of the heater attachment member 52, as shown in FIG. If the bracket has a hole from the beginning, the heater attachment member 52 may not be attached.

  Next, the belt-like heater 5 is inserted along the eaves rod 4 into the inside thereof. Before attaching the heater attachment member 52 to the eaves bracket, a belt-like heater may be inserted along the eaves eaves. The belt-like heater 5 is sufficiently thin and not too long, so it can be easily inserted into the basket. If the eaves are short, a single heater is sufficient, but if the eaves are long, multiple heaters are connected.

  When the heater is inserted, the lower surface and the side surface of the belt-like heater 5 located below the bracket 3 are surrounded by the heater mounting member 51. If the position surrounded by the heater mounting member 51 is directly under the eaves bracket 3, it is effective for suppressing the swing of the belt-like heater 5. It is also possible to enclose (temporarily fix) the lower surface and side surface of the heater with the heater mounting member 51 in advance before charging into the bag.

The type of the heater mounting member 51 is preferably a vinyl tie (vinyl string with a thin wire) if the heater is small or light, and a U-bolt if the heater is large and heavy.
The number of heater mounting members 51 used is preferably the same as the number of eaves brackets. However, when the bracket mounting interval is short at both ends of the eaves or the like, the number of heater mounting members 51 used can be reduced.

Next, the belt-like heater 5 surrounded by the heater mounting member 51 is lifted and positioned below the bracket 3 and slightly above the eaves bottom wall 45. At this time, it is desirable that the bottom of the belt-like heater 5 be as close as possible to the eaves ridge bottom wall 45 so as not to contact the eave ridge bottom wall 45. This is to keep the heat efficiency of the heater high and not to damage the wrinkles.
As a result, the belt-like heater 5 is placed below the bracket 3 perpendicular to the eaves bottom wall 45, that is, the side surface having a relatively large area of the heater is upright, and the longitudinal direction is set parallel to the eaves eaves.
Moreover, if it does in this way, the strip | belt-shaped heater 5 does not block the flow of rainwater in an eaves, and also it suppresses the area which hits sunlight small, and becomes difficult to deteriorate.

Finally, the upper end of the heater mounting member 51 is coupled with the heater mounting member 52 of the eaves bracket 3 so that the belt-like heater 5 does not swing.
If the heater mounting member 51 is a U-shaped bolt, it pierces from the lower part of the bracket into the hole of the heater mounting member 52, and is fitted with a nut at the tip. On the other hand, in the case of a vinyl tie (a vinyl string containing a thin wire), the tip of the wire may be pierced from the lower part of the bracket into the hole of the heater mounting member 52, and the two wires may be twisted together.

As mentioned above, although the fixing method of this invention was explained in full detail with drawing, a concrete structure is not restricted to this.
Each of the above steps is suitable for newly installing a gutter, but the order may be changed when a heater is retrofitted to an existing gutter. That is, the heater 5 may be fixed after the belt-like heater 5 is inserted in the eaves rod in advance and the heater mounting member 51 is attached to the eaves bracket. Alternatively, the heater attachment member 51 can be surrounded at a predetermined interval on the lower surface and side surface of the belt-like heater 5.

  In the eaves device with the heater fixed according to the present invention, rainwater, snow, ice, etc. from the roof falls from the eaves and accumulates in the eaves. From the mouth, it enters the trough and falls into the drain and drainage tank. When rainwater freezes and the snow becomes harder, a large load is applied to the eaves and there is a risk of breakage. Therefore, current is supplied to the heater from a household 100V power source. The belt heater is located slightly above the bottom wall of the eaves so that the snow and ice inside the eaves can be efficiently melted, the eaves are not damaged, and the fall of the icicles can be prevented. Traffic is safe.
