Technical Field
[0001] The utility model relates to the technical field of house structures, in particular to an antifreeze structure for a drainage roof eaves. Background Art
[0002] Gutters are a common drainage structure on roofs. In winter or in cold areas, snow and freezing are easy to accumulate in the gutters, which will cause gutter drainage blockage and affect the normal use of the entire roof drainage system. In order to prevent the freezing of gutters, electric heating is usually used to melt snow. There are generally two ways to set up electric heating for existing gutters: one method is to lay electric heating wires in the open, which has the advantage that electric heating wires are easy to install, repair and replace, but heat is easily wasted and the antifreeze effect is average. In addition, in order to prevent sharp objects from damaging the roof gutter, people cannot step on it when they go up, and the cable needs to pass through the roof to lead to the upper surface of the gutter; the other method is to lay the electric heating cable close to the inside of the gutter bottom plate. The metal plate of the gutter has good thermal conductivity and can also play a role in melting snow, but this method is not easy to install and repair. Summary of the invention

[0012] Furthermore, a roof panel is provided on the eaves, and the roof panel extends above the gutter, and the lowest position of the roof panel is higher than the highest position of the top sealing plate.
[0013] Furthermore, a plurality of wire clips are provided on the inner side of the fascia board, each wire clip having an arc-shaped wire clipping portion and connecting portions provided on both sides of the wire clipping portion, and the connecting portions are connected to the fascia board by means of screws, magnetism or bonding.
[0014] Furthermore, the connecting portion is an elastic structure integrally formed with the wire-holding portion, or the connecting portion is rotatably connected to the wire-holding portion via a rotating shaft.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0025] like Figure 1 and Figure 2 As shown, a drainage roof eaves antifreeze structure includes a gutter 1 (not just a groove, but also an L-shaped gutter structure itself) arranged on the eaves, and a plurality of rainwater pipes 2 connected to and communicated with the gutter 1, a fascia board 3 is provided on the outer side of the gutter 1, and the fascia board 3 extends from the bottom and side of the gutter 1 to the top, including a bottom fascia board 301, a side fascia board 302 and a top fascia board 303, and the top fascia board 303 is provided with a slope inclined toward the groove direction of the gutter 1, and electric heating cables 4 are respectively provided on the side of the bottom fascia board 301 close to the house and at the intersection of the bottom fascia board 301 and the side fascia board 302, and the electric heating cables 4 are arranged along the length of the fascia board 3.
[0026] The drainage roof eave anti-freezing structure can effectively prevent the formation of icicles on the eaves by arranging the eaves plate 3 and the electric heating cable 4 outside the gutter, and has good anti-freezing and anti-snow effects. At the same time, the structure of the eaves plate is improved to facilitate the laying and installation of the electric heating cable.
[0027] Through the above design, the drainage roof eaves is beneficial to anti-freezing in at least three aspects. First, the top sealing plate of the eaves plate 3 is designed to be sloped inward, so that the melted snow water flows inwardly into the gutter, reducing the amount of snow water dripping at the eaves. This measure can also avoid the formation of icicles; second, the side sealing plates of the eaves plate 3 are designed to be vertical surfaces, which can reduce the adhesion and accumulation of snow, reduce the amount of snow accumulation, and reduce the amount of snow water; third, the electric heating wire 4 is set at multiple positions of the eaves plate 3. By adopting a heating method at the dripping point, the snow water can be prevented from condensing at the dripping point, thereby blocking the conditions for the formation of icicles, which can effectively prevent the snow water from condensing at the dripping point or prevent the upper snow water from dripping.
[0028] Through the improvements in these three aspects, not only the formation of icicles on the eaves is greatly avoided and safety is ensured, but also the probability of complete freezing of the gutter 1 and the rainwater pipe 2 can be reduced. By keeping the gutter 1, rainwater pipe 2 and other components at a certain temperature and not freezing, the entire roof rainwater drainage system can function normally.
[0029] Furthermore, the edge of the top sealing plate 303 is provided with a folded edge 304 extending downward, and the electric heating wire 4 is also provided on the inner side of the corner of the folded edge 304. The electric heating wire 4 is also provided there, which can heat and melt the snow gathered above the top sealing plate 303. With the inclined arrangement of the top sealing plate 303, the melted snow and rainwater will slide or flow into the gutter 1. The setting of the folded edge 304 is conducive to the dripping of snow water and prevents the snow water from entering the position between the top sealing plate and the gutter.
[0030] Furthermore, the bottom of the bottom sealing plate 301 is a horizontal plane, the outer side of the side sealing plate 302 is a vertical plane, and the bottom sealing plate 301, the side sealing plate 302 and the top sealing plate 303 are an integrally formed plate structure, which can be mass-produced in a prefabrication plant and installed at the construction site, thereby reducing the amount of construction on site.
[0031] A circular chamfer is arranged on the outer side of the transition between the side sealing plate 302 and the bottom sealing plate 301. Such a smooth chamfer is not only beautiful, but also conducive to the flow of snow water without accumulation.
[0032] Furthermore, the bottom sealing plate 301, the side sealing plate 302 and the top sealing plate 303 are detachably connected to the main structure of the gutter 1 through a plurality of connecting parts 5, for example, the eaves plate 3 is engaged on the outer side of the gutter 1 and then fastened through the connecting parts 5, and the connecting parts 5 can be screws, pins or buckles, etc.
[0033] Further, combined with Figure 3 As shown, the bottom sealing plate 301 is provided with a vertical through hole for the rainwater pipe 2 to pass through, a sealing sleeve 8 is provided at the vertical through hole, and an electric heating element 9 is provided inside the sealing sleeve 8.
[0034] The sealing sleeve 8 is arranged at the vertical through hole to ensure the sealing of the rainwater pipe 2 at this location, preventing the snow water in the gutter from flowing down along the outer wall of the rainwater pipe 2, and the sealing sleeve 8 can also be used to further fix the rainwater pipe 2; the electric heating element 9 arranged therein can heat at this node to prevent the rainwater pipe from freezing at this node. The electric heating element 9 can be an electric heating wire or a heating belt.
[0035] In order to prevent the accumulation of ice and snow at the rainwater pipe outlet and cause blockage, the appropriate density of gutter electric heating tapes within 1m around the rainwater pipe outlet will achieve better results. The rainwater bucket can be an electric heating finished stainless steel rainwater bucket, which can melt the snow and ice at the rainwater pipe outlet and achieve the function of timely clearing the ice and snow at the rainwater pipe outlet.
[0036] In addition, different treatment measures can be taken according to the different environments in which the rainwater pipe 2 is located. Rainwater pipes located in indoor heating spaces will not freeze; those located in other environments can be protected from freezing by adopting electric heating measures. There are generally two methods for setting up electric heating for the rainwater pipe 2: one method is to arrange it outside the pipe, to place the electric heating wire close to the rainwater pipe, and to set an insulation layer on the outside. The advantage of this method is that the electric heating wire can be set at any section of a rainwater pipe; the other method is to insert it into the pipe. The electric heating wire inserted into the pipe can directly contact the ice and snow in the pipe, and the antifreeze effect is better. At the same time, in order to maximize the use of the heat energy of the electric heating wire, an insulation layer is set on the outside of the rainwater pipe 2.
[0037] Furthermore, a roof panel 6 is provided on the eaves, and the roof panel 6 extends above the gutter 1. The lowest position of the roof panel 6 is higher than the highest position of the top sealing plate 303. With this height difference, even if the rainwater in the gutter 1 is full, it will not flow back toward the roof surface.
[0038] Further, combined with Figure 4 As shown, a plurality of wire clips 7 are provided on the inner side of the fascia board 3. The wire clip 7 has an arc-shaped wire clipping portion 701 and connecting portions 702 arranged on both sides of the wire clipping portion 701. The connecting portions 702 are connected to the fascia board 3 by screws, magnetism or bonding.
[0039] The line card 7 has a simple structure, is easy to use and install, and can better restrain the electric heating cables 4, allowing the electric heating cables to be installed along a preset path for laying, and is also convenient for disassembly during later maintenance.
[0040] Furthermore, the connecting portion 702 is an elastic structure integrally formed with the wire clamping portion 701 and has a certain elasticity, which can better wrap and clamp the electric heating wire 4. The elastic structure can be a metal spring.
[0041] In some embodiments, Figure 5 As shown, the connecting portion 702 is rotatably connected to the wire clamping portion 701 via a rotating shaft, so that the angle between the connecting portion 702 and the wire clamping portion 701 can be adjusted according to the installation position of the electric heating cable so that it can be connected and fixed to the eaves board 3.
[0042] Furthermore, it also includes a thermostat arranged in the house, the thermostat is connected to the electric heating line, and a temperature sensor is also arranged at the gutter or the eaves board, and the temperature sensor is also connected to the thermostat.
[0043] The arrangement of the temperature sensor and the temperature controller facilitates the control and automatic operation of the electric heating wire and other electric heating elements, and snow melting and drainage are purposefully performed according to temperature changes and freezing conditions.
[0044] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
