Abstract

The utility model discloses a rainwater hopper rain discharging system with an elbow stainless steel pipe. The rainwater hopper discharging system comprises a cast-iron perforated strainer, an elbow steel pipe and a direct connector, the elbow steel pipe is a curved pipe composed of an upper vertical section, an upper elbow, a tilting section, a lower elbow and a lower vertical section, the cast-iron perforated strainer is provided with sub-strainers, and the direct connector is a feedthrough pipe joint; the cast-iron perforated strainer is arranged on a pipe orifice of the upper vertical section of the elbow steel pipe, the sub-strainers of the cast-iron perforated strainer are inserted into the pipe orifice of the elbow steel pipe, and the direct connector is connected onto the tail end of the lower vertical section of the elbow steel pipe. Since the elbow steel pipe is integrally formed by the vertical sections, the elbows and the tilting section, and structure setting of a roof gutter and a linkage rod are unchanged, space is effectively utilized, and collision of a joint space of a rainwater hopper and the linkage rod is avoided. Therefore, the rainwater hopper rain discharging system has the advantages of being simple in structure and convenient to construct and mount.

Description

A kind of band elbow stainless steel tube roof drain rain heat-extraction system

Technical field

The utility model relates to building rain water discharge technology field, for the gutter of building roof and being connected of rain pipe, and especially a kind of band elbow stainless steel tube roof drain rain heat-extraction system.

Background technology

In the design of steel roofing stainless steel gutter, for meeting Structural Tectonics designing requirement, optimize steel structure member and arrange to reach the object of saving steel, employing arranges and links bar in stainless steel gutter bottom, weld gutter rest for jacking stainless steel gutter linking on bar, owing to linking bar, be positioned at stainless steel gutter bottom, not only be arranged in parallel with stainless steel gutter, and vertical distance is nearer, the problem existing is, while roof drain and rain heat-extraction system being set according to conventional method, because stainless steel gutter is with to link bar vertical distance less, and that roof drain stretches out gutter is downwards longer, the extended position of roof drain with link bar and clash, due to narrow space, cause downspout elbow to arrange very difficult, construction and installation are also very inconvenient.

Utility model content

The purpose of this utility model is a kind of band elbow stainless steel tube roof drain rain heat-extraction system providing for the deficiencies in the prior art, the utility model takes vertical section, elbow and tilting section to be made for the curved steel pipe of one, neither change gutter and link the structure setting of bar, effectively utilized space, avoided again roof drain and linked bar conflicting in connection space, have simple in structure, the advantage of construction install convenience.

The concrete technical scheme that realizes the utility model object is:

A kind of band elbow stainless steel tube roof drain rain heat-extraction system, its feature comprise cast iron double-edged fine-toothed comb, curved steel pipe and directly described in joint 3 curved steel pipe by the vertical vertical section curved tube forming in section, upper elbow, tilting section, lower elbow and bottom in top, cast iron double-edged fine-toothed comb is provided with rim of the mouth, and directly joint is straight-through union; Described cast iron double-edged fine-toothed comb is located at the vertically mouth of pipe of section of curved steel pipe top, and the rim of the mouth of cast iron double-edged fine-toothed comb is plugged in the mouth of pipe of curved steel pipe, and directly joint is connected in the vertically end of section of curved steel pipe bottom.

The utility model takes vertical section, elbow and tilting section to be made for the curved steel pipe of one, neither change gutter and link the structure setting of bar, effectively utilized space, avoided again roof drain and linked bar in the conflicting of connection space, have simple in structure, the advantage of construction install convenience.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is use view of the present utility model.

The specific embodiment

Consult Fig. 1, the utility model comprises cast iron double-edged fine-toothed comb 1, curved steel pipe 2 and direct joint 3, described curved steel pipe 2 is by the vertical section 21 in top, upper elbow 22, tilting section 23, lower elbow 24Ji bottom vertical section 25 curved tubes that form, cast iron double-edged fine-toothed comb 1 is provided with rim of the mouth 11, and directly joint 3 is straight-through union; Described cast iron double-edged fine-toothed comb 1 is located at the vertically mouth of pipe of section 21 of curved steel pipe 2 tops, and the rim of the mouth 11 of cast iron double-edged fine-toothed comb 1 is plugged in the mouth of pipe of curved steel pipe 2, and directly joint 3 is connected in the vertically end of section 25 of curved steel pipe 2 bottoms.

The utility model is to use like this:

Consult Fig. 1, Fig. 2, the design adopts whole curved steel pipe 2 to replace stainless steel roof drain, rain pipe and the connecting bend of conventional roofing rain heat-extraction system, during use, as long as by rainwater hole welding reserved on the mouth of pipe of the vertical section 21 in curved steel pipe 2 tops and stainless steel gutter 4, the curved steel pipe 2 bottoms vertically end of section 25 are connected with UPVC rain pipe 6 by direct joint 3, can complete connection of the present utility model.

The design and fabrication of the curved steel pipe of the utility model

According to steel roofing stainless steel gutter 4, link the structure design of bar 5 and rest 7, design the curved steel pipe 2 that meets structural requirement, by top, vertically section 21, upper elbow 22, tilting section 23, vertical Duan25Wu Ge position, lower elbow 24Ji bottom form curved steel pipe 2, wherein, top vertically section 21 is roof drain, by the turnover of upper elbow 22, tilting section 23 and lower elbow 24, can avoid roof drain and link bar 5 in the conflicting of connection space, by direct joint 3 by bottom vertically section 25 be connected with UPVC rain pipe 6; By design caliber, wall thickness, select stainless steel tube, example: stainless steel tube caliber is that 108 mm, wall thickness are that the diameter of 1.8mm, UPVC rain pipe 6 is 110 mm; Press plan, with bending machine, make and comprise the vertically curved steel pipe 2 at section 21, upper elbow 22, tilting section 23, vertical Duan25Wu Ge position, lower elbow 24Ji bottom of top.

Implementation process of the present utility model

During installation, as long as by rainwater hole welding reserved on the mouth of pipe of the vertical section 21 in curved steel pipe 2 tops and stainless steel gutter 4, the curved steel pipe 2 bottoms vertically end of section 25 are connected with UPVC rain pipe 6 by direct joint 3, on curved steel pipe 2 or on UPVC rain pipe 6, geometrical clamp 8 to be set, finally the rim of the mouth of cast iron double-edged fine-toothed comb 1 11 is placed in the mouth of pipe of the vertical section 21 in curved steel pipe 2 tops, rainwater can be from steel roofing stainless steel gutter 4 by cast iron double-edged fine-toothed comb 1, rainwater hole enters curved steel pipe 2, by direct joint 3, enter UPVC rain pipe 6 again, finally complete row's rainwater work of roof drain and rain heat-extraction system.The visual steel roofing of the size stainless steel gutter 4 at the curved steel pipe of the utility model 2 Wu Ge positions, the structure that links bar 5 and rest 7 are adjusted, to meet different stainless steel gutters 4 in design specifications and to link the demand of bar 5 structures.
