An ear 14 at the upper end of the side wall 13 behind the eaves gutter is inserted into a groove provided at the rear end of the eaves gutter 41 and is attached to the wall surface of the building 5.

[0003]

[Problems to be solved by the invention]

 However, as described above, in the internal suspension type eaves gutter described in Japanese Utility Model Laid-Open Publication No. 3-76934, the front end of the main body 61 of the gutter mounting bracket 6 is formed by the ear at the upper end of the front side wall 2. 4 is only anchored at the lower base of the eaves gutter, and mounting by the gutter mounting bracket 6 is unstable. There was a drawback that it easily deviated from 6.

The present invention has been made by focusing on such problems in the conventional internally suspended eaves gutter, and aims at solving the problems in the conventional internally suspended eaves gutter. An object of the present invention is to provide an eaves gutter which is stable and can be easily attached to the gutter attachments by a load caused by snow or wind blown from below the eaves gutter.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the eaves gutter of the present invention has a bottom portion, front and rear side walls, and ear portions at upper ends of both side walls, and a thermoplastic resin coating layer is provided on both sides of a core material made of a fiber-reinforced composite sheet. In the eaves gutter composed of the laminated structure provided, a protrusion projecting inward of the eaves gutter is provided in the middle of the inner surface of the front side wall, and the ear at the upper end of the front side wall is inside the eaves gutter. The above-mentioned configuration solves the above-mentioned problem.

[0006] In the present invention, the material of the eaves gutter is not particularly limited. For example, in addition to synthetic resins such as hard vinyl chloride resin, polyethylene, polypropylene, and polycarbonate, engineering plastics such as polyphenylene sulfide. Or a metal such as iron, stainless steel, copper, or aluminum may be used alone, or these materials may be used, such as providing a hard vinyl chloride resin coating layer on both sides of a metal core material such as iron. May be used in appropriate combination. The core material may be a metal plate or a net, and a fiber-reinforced composite sheet or the like may be used in addition to metal.

[0007] The fiber-reinforced composite sheet includes roving-like continuous fibers such as glass fiber, carbon fiber, alumina fiber, and aramid fiber alone or in combination thereof, and processed products such as nonwoven fabric, woven fabric, mat, and net. A resin-impregnated resin can be used, and a multilayer structure obtained by combining these can be used.

[0008]

[Action]

 In the eaves gutter of the present invention, a protruding portion is provided in the middle of the inner surface of the front side wall to protrude inward of the eaves gutter, and the ear at the upper end of the front side wall protrudes inward of the eaves gutter. As a gutter fitting, not only a part to be locked to the lower root of the ear at the upper end of the front side wall, but also a concave part to which a protruding part protruding into the middle part of the inner surface of the front side wall is provided. The use of the gutter mounting member makes the mounting state with the gutter mounting bracket stable, and does not easily come off from the gutter mounting bracket due to a snow load or a wind blown from below.

[0009]

【Example】

 Next, embodiments of the present invention will be described with reference to the drawings. Embodiment 1 FIG. 1 is a cross-sectional view showing an attached state of an example of the eaves gutter of the present invention. In FIG. 1, reference numeral 1 denotes an eaves gutter of the present invention. The eaves gutter 1 of the present invention has a bottom 11, a front side wall 12, a rear side wall 13, and ears 14, 14 at the upper ends of both side walls. The body has a sandwich structure in which a hard vinyl chloride resin coating layer 3 is provided on both sides of a core material 2 made of a fiber reinforced composite sheet.

In the middle of the front side wall 12, a part of the hard vinyl chloride resin coating layer 3 is formed to be thick, and a ridge 15, which is a projection projecting inward from the eaves gutter 1, is formed. 1 over the entire length. The ear 14 at the upper end of the front side wall 12 protrudes inward of the eaves gutter 1, and the ear 14 at the upper end of the rear side wall 13 protrudes out of the eaves gutter 1.

Reference numeral 4 denotes a gutter mounting bracket. A base 41 of the gutter mounting bracket 4 is mounted on a wall surface of the building 5, and a front end of a main body 42 of the gutter mounting bracket 4 is fitted with the ridge 15 of the eave gutter 1. A concave groove 43 is provided, and a locking portion 44 is erected above the front end of the main body portion 42. The upper end of the locking portion 44 engages the base of the ear portion 14 at the upper end of the side wall 12 in front of the eaves gutter 1. It has been stopped. At the rear end of the main body portion 42 of the gutter mounting bracket 4, there is provided a concave groove 45 which fits into the ear portion 14 at the upper end of the side wall 13 behind the eaves gutter 1. A protruding ridge 46 that is locked to the lower base is protruded.

Next, the operation of the eaves gutter of the present invention shown in FIG. 1 will be described. As shown in FIG. 1, the ear 14 at the upper end of the side wall 13 behind the eaves gutter 1 is inserted into the groove 45 of the main body 42 of the gutter mounting bracket 4, and the ear is formed by the ridge 46 at the entrance of the groove 45. At the same time, the lower root of the portion 14 is locked, and the ridge 15 projecting from the middle of the front side wall 12 is inserted and fitted into the concave groove 43 of the main body 42 of the gutter mounting bracket 4. The eaves gutter 1 is attached to the wall of the building 5 by engaging the locking portion 44 above the front end of the eaves gutter 1 with the base of the ear 14 at the upper end of the side wall 12 in front of the eaves gutter 1.

In such a state, even if a snow load is applied or the wind blows up from below the eaves gutter 1, the gutter mounting bracket 4 is attached to the base of the upper end 14 of the side wall 12 in front of the eaves gutter 1. Not only the locking portion 44 is locked, but also the ridge 15 projecting from the middle of the side wall 12 in front of the eaves gutter 1 is fitted into the groove 43 of the gutter mounting bracket 4. The eaves gutter 1 is attached to the gutter mounting bracket 4 in a stable state, and the eaves gutter 1 does not come off from the gutter mounting bracket 4.

Next, a method of manufacturing the eaves gutter of the present invention shown in FIG. 1 will be described. FIG. 2 is an explanatory view showing a mode of manufacturing the fiber-reinforced composite sheet as the core material 2 of the eaves gutter shown in FIG.

As shown in FIG. 2, the fiber reinforced composite sheet is obtained by unwinding a glass fiber 20 from a bobbin 24, impregnating a vinyl chloride resin 22 in an impregnated layer 21, and heating and pressing with a pinch roll 23. A core material 2 made of a sheet of a vinyl chloride resin 22 reinforced with glass fibers 20 is manufactured.

FIG. 3 is an explanatory view showing a mode in which the eaves gutter of the present invention is manufactured using the core material 2. As shown in FIG. 4, in the eaves gutter of the present invention, the core material 2 fed from the bobbin 57 is introduced into a forming device 51 and formed into a substantially gutter shape. The ends of the gutter-shaped core material 2 are gradually wound around the rod-shaped core 52 at both ends to form ears of the eaves gutter, and then introduced into a crosshead die 55 attached to an extruder 54. The resin material is coated on the inner and outer surfaces of the core material 2, the shape of the core material 2 is corrected by passing through the sizing die 56, and the core material 2 is taken by the take-up machine 56.
