Abstract

The utility model relates to a rainwater pipe which is made of iron sheet in a water rolling mode. The inner and the outer surfaces are provided with porcelain enamel; the left and the right side surfaces of the front surface of a down pipe are provided with convex ribs. The utility model has simple structure, beautiful appearance and high durability, having no pollution for walls. The utility model can be invested and mounted by one step, and can not be replaced or maintained for a long term, which basically solves the long-term unsolved problem that an existing rainwater pipe has easy damage and short service life.

Description

Rainwater pipe

The utility model belongs to building constructions accessory technical scope, relates to a kind of rainwater pipe.

The rainwater pipe of prior art, generally there are tin plate rainwater pipe, glass fiber reinforced plastic rainwater pipe, plastics rainwater pipe and cast iron rainwater pipe etc. several, the easy corrosion of tin plate rainwater pipe is rotted, rust water pollutes wall, though the external surface that has japanning, but enamelled coating comes off easily, can not reach the requirement that prevents corrosion, glass fiber reinforced plastic rainwater pipe and plastics rainwater pipe are not generally established reinforcing rib, weathering easily, aging distortion, debacle, the same with tin plate rainwater pipe, all damage easily, often need or periodic maintenance and replacing, application life is short; Cast iron rainwater pipe, because tube wall is thicker, rust resistance is stronger, but only can correspondingly increase service life, can not fundamentally solve short problem in application life, and relatively heavier, effort is installed, attractive in appearance inadequately, also still exist rust water to pollute the problem of wall.Therefore, rainwater pipe problem is difficult problem that must not solve for many years on the building constructions.

Task of the present utility model provides a kind of attractive in appearance, novel rainwater pipe of not polluting wall, long service life, to overcome the existing above-mentioned deficiency of prior art rainwater pipe.

Task of the present utility model realizes with following scheme: it comprises leak bucket and leader two parts, make by iron sheet, the leader partial cross section becomes rectangle, its main points are that its leader front and left and right two sides are all risen and established vertical convex tendon, and the surfaces externally and internally of leak bucket and leader is all warded off system enamel.Thereby establish convex tendon by rising in the side of rainwater pipe, guarantee in the enamel technology process indeformable, the problem of by surfaces externally and internally enamel, overcome fundamentally that the rainwater pipe is fragile, application life is short.

Below in conjunction with accompanying drawing the utility model is elaborated:

Fig. 1 is a front view of the present utility model

Fig. 2 is a lateral view of the present utility model

Fig. 3 is the sectional view of leader part

Fig. 4 is a leader partial cross section partial enlarged drawing

According to Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises leak bucket 1 and leader 2 two parts, can be made by iron sheet, and the cross section of leader 2 is a rectangle, and convex tendon 3 has longitudinally all been played in front and left and right two sides; According to shown in Figure 4,5 is iron sheets among the figure, and its surfaces externally and internally is all warded off and is shaped on enamel 4.

For further preventing the distortion of leader 2 in the enamel technology process, improve aesthetic measure, above-mentioned said leader front and left and right two sides are all risen and are established vertical convex tendon, can be all to rise to establish two vertical convex tendons.

Because the surfaces externally and internally of rainwater pipe is all warded off system enamel, thereby can be enough to guarantee its etch-proof performance.Be reducing manufacturing cost, saidly make with iron sheet, can be to make with cold rolling iron sheet.

The utility model is simple in structure, and is attractive in appearance, durable, can not cause wall to pollute, one-time investment is installed in the time of can accomplishing to build the building, need not change and keep in repair for a long time, be without fear of an attack from the rear, solved fundamentally that existing rainwater pipe is fragile, application life short this difficult problem that must not solve for a long time.

Claims

1, a kind of rainwater pipe, comprise leak bucket 1 and leader 2 two parts, make that leader 2 cross sections become rectangle by iron sheet 5, vertical convex tendon 3 has all been played in the leader front and left and right two sides that it is characterized in that it, and the surfaces externally and internally of leak bucket 1 and leader 2 is enamel 4 all.

2, rainwater pipe according to claim 1 is characterized in that said leader 2 fronts and left and right two sides have all played vertical convex tendon 3, is all to have played two vertical convex tendons.

3, rainwater pipe according to claim 1 is characterized in that said iron sheet 5 makes, and is cold rolling iron sheet.
