However, various types of gutters having different cross-sectional sizes such as the width of the bottom wall and the height of each side wall depending on the size of the greenhouse are used as the gutter. However, as described above, when an extrusion-molded material such as aluminum is used as the material of the gutter material and the bottom wall and each side wall are integrally formed, the cross-sectional size of the bottom wall and each side wall is limited due to the restriction of the extrusion molding machine. Therefore, a gutter material corresponding to a large greenhouse cannot be formed by a commonly used extruder, and a large extruder corresponding to a large gutter material is prepared. There was a need, and there was a problem that was uneconomical. In addition, when the extruder is used to form an integral extruded mold having the bottom wall and each side wall, the flow of molten metal is poor, and the thickness of the bottom wall and each side wall is not uniform. In addition, in order to cope with the problem of non-uniformity, that is, considering the strength of a portion where the thickness is reduced due to the variation of the molten metal flow, the entire thickness is set to a large value in advance and a predetermined strength is set. In this case, however, there is a problem that a material loss is caused and the cost is increased. In addition, when the bottom wall and each side wall are integrated to form a gutter material, the finished dimension becomes large, and when transporting or storing, it is bulky and inconvenient for transporting or storing. There were also problems.

An object of the present invention is to make it possible to manufacture a large gutter material using a small extruder, while easily changing the cross-sectional size by combining the bottom wall and each side wall.
Still further, the present invention provides a gutter material which has no problem of water leakage, has a good flow of molten metal at the time of molding, can obtain necessary strength without incurring material loss and high cost, and can further reduce bulk in transportation and storage. It is in.

Also, the by a combination of the divided trough members 1 and of being easily obtained a different trough material of cross-sectional sizes. In addition, since each of the divided gutter members 1 can be separately formed, each of the divided gutter members 1 can be reduced in size as compared with the case where the entirety of the gutter members is integrally formed. Can be formed by using an extruder, and the workability thereof can be improved, and a large-sized gutter can be obtained by connecting the divided gutters 1 to each other. It is possible to manufacture a large gutter material while increasing the size of each of the divided gutter members 1 as described above. The entire wall thickness can be made substantially uniform, so that it is not necessary to set the entire wall thickness large in consideration of the variation of the molten metal flow, as in the conventional case of integrally forming the entire gutter material,
As a result, the required strength can be ensured while reducing the thickness of each of the divided gutter members 1 to a minimum thickness without incurring a material loss or an increase in cost. By doing so, the bulk can be reduced, so that it can be convenient for transportation and storage.

According to the second aspect of the present invention, since the storage groove 5 of the sealing material 4 is provided on at least one of the male fitting portion 2 and the female fitting portion 3, the respective fitting portions are provided. A sufficient amount of the sealing material 4 can be filled between the fitting portions 2 and 3, and the sealing material 4 does not come out to the outside during use. The gap can be closed, and water leakage can be reliably prevented.

Further, according to the third aspect of the present invention, the male fitting portion 2 and the female fitting portion 3 are fitted so as to be rotatable relative to each other, and the one-side split gutter 1 is connected to the other. Since the relative angle of the side split gutter members 1 is made adjustable and is joined at the adjusted predetermined angle, the work of inserting the male fitting portion 2 into the female fitting portion 3 can be easily performed. Can do
Moreover, by relatively rotating the divided gutter members 1 via the fitting portions 2 and 3, the mounting angle of each of the divided gutter members 1 can be easily adjusted, and the side wall portion of the gutter member can be adjusted. The degree of freedom of the inclination gradient is obtained, and the sectional shape of the gutter material by each of the divided gutter materials 1 can be easily changed and adjusted to an arbitrary shape according to the form of the greenhouse.

According to the fourth aspect of the present invention, the divided gutter 1 is composed of a bottom divided gutter 11 forming a bottom wall and a pair of side divided gutters 12 and 13 forming a side wall. The male fitting portion 2 and the female fitting portion 3 provided at the connection side end of the bottom divided gutter member 11 and the side divided gutter members 12 and 13.
Are fitted so as to be rotatable relative to each other, and the side divided gutter members 12 and 1 are fitted.
3 is connected to the bottom divided gutter member 11 so as to be adjustable in relative angle and is coupled at an adjusted predetermined angle. Therefore, when assembling the gutter material, the side divided gutter with respect to the bottom divided gutter member 11 is connected. By adjusting the relative angles of the members 12 and 13, not only can the width intervals of the side divided gutter members 12 and 13 be easily changed, but also the divided gutter members 11 and 1 can be easily changed.
The cross-sectional size of the gutter material can be easily changed by selecting 2, 13 and the gutter material of various shapes corresponding to the greenhouse can be easily manufactured, which can be very excellent in versatility. In addition, by dividing the gutter material into three divided gutter materials 11 to 13, each of these members can be further reduced in size, and a larger gutter material can be manufactured using a small extruder. In addition, as described above, since each of the divided gutter members 11 to 13 can be further improved in the flow of molten metal when being formed by the extruder, without causing a material loss or a high cost, The required strength can be ensured while making each of the divided gutter members 11 to 13 the minimum thickness, and the gutter material is divided into three divided gutter members 1.
1 to 13 to form these split gutter members 11 to 1
3 can be formed in a substantially plate shape, so that its bulk can be reduced, and it can be made more convenient when carrying or storing.
