[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trough formed into a cylindrical shape by a strip material and a connecting material.

0002

[Prior Art] Conventionally, cylindrical downpipes have been formed into long lengths by extrusion molding, etc., and these long lengths are cut into multiple types of predetermined lengths depending on the usage situation. It is designed to form a vertical gutter. On the other hand, there is also known a seam connection in which the longitudinal side edges of a long strip material are bent outward to project, and the projecting portions are connected by a clamping member.

0003

[Problem to be Solved by the Invention] However, in the case of the former mentioned above, since the vertical gutter is formed in a cylindrical shape from the beginning, it is bulky, and when stored as inventory, it is difficult to store it. There is a problem that it takes up a lot of space, and there is also a problem that it takes up a lot of storage space when transporting it.In addition, in the latter case, the accuracy of the joining state may vary depending on the operator who performs the joining work. There is a problem in that only a skilled worker can perform the joining work, and a joining tool is required.

[0004] The present invention aims to solve the above-mentioned problems, and aims to provide a downpipe that can be reduced in bulk and that can be joined even by non-skilled workers. be.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention comprises a strip material 1 that can be rolled up and a connecting material 2 formed in an elongated length. The fitting protrusions 1a with a sawtooth cross section provided on both side edges extending over the length are engaged with the fitting recesses 2a with a sawtooth cross section provided on both side edges extending in the longitudinal direction of the connecting member 2, so that the strip material 1 is shaped into a cylinder. It was formed.

[0006]

[Function] By keeping the strip material 1 rolled up, the bulk can be reduced, and it does not take up a large amount of storage space during storage, and it also does not take up a large amount of storage space during transportation. There is no. Furthermore, when forming the strip material 1 into a cylindrical shape using the connecting material 2, the fitting protrusion 1 of the strip material 1 is inserted into the fitting recess 2a of the connecting material 2.
The connection can be made by simply fitting a.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on illustrated embodiments. As shown in FIG. 1, the main body of the downpipe is composed of a strip-shaped material 1 formed in an elongated length and a connecting member 2 formed in an elongated length like the strip-shaped material 1. Strip material 1
is constructed by inserting a thin metal plate 3 into a synthetic resin such as vinyl chloride, and can be wound up as shown in FIG. This strip material 1
is curved in the lateral direction, and in the stretched state, both edges in the longitudinal direction are close to each other and form a cylindrical shape. Fitting protrusions 1a each having a sawtooth cross section are formed on both edges of the strip material 1 in the longitudinal direction. The connecting member 2 is elongated like the strip material 1, and is made of vinyl chloride, which is harder than the synthetic resin that makes up the strip material 1. The connecting member 2 has an E-shaped cross section, and fitting recesses 2a each having a sawtooth cross section are formed on both longitudinal edges thereof. The fitting protrusions 1a provided on the strip material 1 are fitted into the fitting recesses 2a, and the fitting protrusions 1a provided on both side edges of the strip material 1 are respectively fitted into the fitting recesses 2a. The strip material 1 is formed into a cylindrical shape.

FIG. 3 shows another embodiment of the present invention, in which the strip material 1 is connected by a connecting member 2 so as to form a rectangular tube shape. It is shown that it constitutes a vertical gutter. FIG. 4 shows a state in which the above-mentioned downpipe is installed on the building body 5 using the holding fittings 4. Since the strip material 1 can be rolled up, when storing or transporting it, it can be rolled up as shown in Figure 2 to reduce its bulk. In addition, when forming a cylinder, the fitting protrusion 1a, which has a sawtooth cross section, can be simply fitted into the fitting recess 2a to easily connect the cylinder without the need for any joining tools. It can be formed into a shape.

[0009]

Effects of the Invention As described above, the present invention is constituted by a windable strip material and a connecting material formed in a long length. The fitting protrusion of the connecting member is engaged with the fitting recess having a sawtooth cross section provided on both longitudinal edges of the connecting member to form the band-shaped material into a cylindrical shape, so that the band-shaped material cannot be wound up. By keeping it in the same state, it can be made low-volume, so it does not take up a large amount of storage space during storage, and it also does not take up a large amount of storage space when being transported. Furthermore, when forming a band-shaped material into a cylindrical shape using a connecting material, the connection can be made without the need for a joining tool etc. by simply fitting the fitting protrusion of the band-shaped material into the fitting recess of the connecting material. It is something that can be done.
