Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a structure of a call gutter connecting a collector and a downspout.

[Prior Art] A conventional call gutter 4 'is a long single piece formed by extrusion, and is provided at an upper end of an elbow 6 and a vertical gutter 7 connected to a lower end of a water collector 5 as shown in FIG. Elbow 8 connected
A long calling gutter 4 'is arranged between the two and the ends of the calling gutter 4' are fitted into elbows 6 and 8, respectively, and connected.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, since a single long genuine gutter 4 'is used, the elbows 6 and 8 on both sides are preliminarily connected to the water collector 5 and the down gutter 7. After the connection of the call gutter 4 ', the connection order of the call gutter 4' cannot be established. Therefore, the order of construction is limited. There is a problem that the fixing of the water vessel 5 or the downspout 7 must be performed once, and when the construction is performed, if the distance between the two elbows 6 and 8 is different, one long outpipe 4 is required at the site. ′ Requires an operation of cutting, and there is a problem that workability is poor.

The present invention has been made in view of the above-described problems of the conventional example, and aims at simplifying the construction, not limiting the construction order, and further, requiring no cutting at the site. To provide a gutter structure.

[Means for Solving the Problems] The structure of the call gutter according to the present invention is such that a concave portion is formed by a fixed pinch in the longitudinal direction on the outer surface of a water-side pipe 2 having a connection enlarged-diameter portion 1 at one end formed by blow molding. Alternatively, a protrusion is formed as a mark, and the other end of the water-side pipe 2 is inserted into the end of the water-side pipe 3 formed by extrusion molding so as to be deep and shallow. By adopting such a configuration, the problems of the conventional example described above have been solved and the object of the present invention has been achieved.

[Action] However, by fitting the other end of the water-side pipe 2 having the connection enlarged-diameter portion 1 at one end thereof into the end of the water-downside pipe 3 so as to be shallow and shallow, the call gutter 4 is constructed, In the dimensional adjustment in the above, it is necessary to adjust the fitting depth of the water-side pipe 2 and the water-side pipe 3, and if the water-side pipe 2 is fitted into the water-side pipe 3. However, since the connection enlarged-diameter portion 1 is provided at one end of the water-side pipe 2, one end of the water-side pipe 2 is connected to the water-downside pipe 3 in the same manner as the conventional gutter 4 formed by one-piece extrusion. It can be the same diameter and can be connected to the same elbow as before,
Although the water-side pipe 2 is formed by blow molding even though it has the connection enlarged-diameter portion 1, there is no problem in molding.

EXAMPLES The present invention will be described in detail based on examples shown in the accompanying drawings.

The call gutter 4 is composed of the water upper pipe 2 and the water lower pipe 3. The water-side pipe 2 is formed by blow molding, and has an enlarged-diameter portion 1 for connection at one end. The downcomer pipe 3 is formed by extrusion molding, and the enlarged diameter portion 1 for connection and the downcomer pipe 3 formed by extrusion molding have the same diameter. Then, the other end of the water-side pipe 2 having the enlarged diameter portion 1 for connection at one end formed by the blow molding described above is freely and shallowly fitted into the end of the water-side pipe 3 formed by extrusion. Is formed.

As shown in FIG.
Are arranged between an elbow 6 connected to the lower end of the vertical gutter 7 and an elbow 8 connected to the upper end of the downspout 7, and both ends of the call gutter 4 are fitted into the elbows 6 and 8, respectively, and connected. That is, the connecting enlarged diameter portion 1 at one end of the water-side pipe 2 of the call gutter 4.
Into the end of the elbow 6 for connection, and the end of the underwater pipe 3 to the end of the elbow 8 for connection.
In this case, the water collector 5 and the downspout 7 are previously constructed, the elbows 6 and 8 are connected to the water collector 5 and the downspout 7, and then the upper pipe 2 and the lower pipe 3 are fitted. Increase the joint depth and call gutter 4
Is disposed between the elbows 6 and 8 in a contracted state, and the calling gutter 4 is extended so that the fitting depth of the water-side pipe 2 and the water-downside pipe 3 becomes shallow, thereby increasing the diameter of the water-side pipe 2 for connection. The part 1 is fitted and connected to the elbow 6, and the end of the underwater pipe 3 is fitted and connected to the elbow 8. Of course, in installing the callout 4, a water collector 5 is installed, an elbow 6 is connected, the connecting enlarged-diameter portion 1 of the water-side pipe 2 is fitted into the elbow 6, and then the elbow 8 is placed under the water. The work sequence may be such that the pipe is connected to the side pipe 3 and then the downspout 7 is connected to the elbow 8 and the downpipe 7 is attached to a wall or the like. , The gutter 4, the elbow 6, and the water collector 5 in this order.

By the way, when both the upper pipe 2 and the lower pipe 3 are blow-molded, the outer surface of the blow-molded article is generally rough, and when it is fitted freely in shallow depth, the sliding property is poor. Is formed by extrusion,
The extruded product has a plasticizer wax on the outer surface and has good slidability, and the water-side tube 2 of the blow-molded product is fitted into the water-side tube 3 made of the extruded product having good slidability. The sliding property is improved.

Here, although not shown in FIGS. 1 and 2, in the present invention, as shown in FIG. 3, the outer surface of the water-side pipe 2 formed by blow molding is recessed at a constant pitch in the longitudinal direction. 10 or a projection is formed so that it can be used as a mark of the fitting depth with the underwater pipe 3.

[Effects of the Invention] In the present invention, as described above, concave or convex portions are formed at a constant pitch in the longitudinal direction on the outer surface of a water-side pipe having a connection enlarged-diameter portion at one end formed by blow molding. Since the other end of the water-side pipe is inserted into the end of the water-side pipe formed by extrusion molding so that it can be freely deep and shallow,
At the time of dimensional adjustment at the site, it is possible to adjust the size by adjusting the fitting depth of the upper pipe and the lower pipe, and it is not necessary to cut it as in the past, and furthermore, the outer surface of the Since a concave or a convex is formed at a constant pitch in the direction, it can be used as a mark of the fitting depth with the underwater pipe. Further, even though the water-side pipe is fitted into the water-side pipe, the connection-side enlarged-diameter portion is provided at one end of the water-side pipe, so that the water-side pipe is formed in the same manner as a conventional single-piece extruded gutter. One end of the pipe can be made the same diameter as the underwater pipe and can be connected to the same elbow as before, and the water pipe is formed by blow molding even though it has a connection enlarged diameter part. Therefore, a water-side pipe having a connection enlarged-diameter portion can be formed without any problem in molding.
