Abstract
The utility model relates to a rain pipe, which comprises a straight pipe, a socket pipe body and fixing lugs, wherein, the fixing lugs are provided with fixing holes. The utility model is characterized in that two fixing lugs are respectively arranged on both sides of the socket pipe body; the bulging wall surface part of the socket pipe body is provided with a reinforcing rib; a pipe body of the bulging wall surface of the socket pipe body is a convex arc surface; the straight pipe is a cylindrical pipe body. Whole products are cast by metal molds continuously best. The utility model has the advantages of simple structure, material saving, light weight, high strength, simple and convenient structure and installation, and beautiful appearance, and conforms to requirements of high-rise buildings.
Description
The utility model belongs to a kind of skin rainwater pipe.
Skin rainwater pipe adopts glass fiber reinforced plastic or cold rolling sheetmetal or other chemical fibre to be composited mostly, and its disadvantage is perishable damage or ageing failure, causes shorten greatly application life.Secondly structurally comparatively complicated, and must make it to be connected with other steel construction pieces with body of wall, bring the inconvenience of installing and loaded down with trivial details, the while complexity of structure must be brought the complicated of manufacturing process, and its comprehensive function value is relatively poor.Moreover product uses the no any recycling in the back of losing efficacy to be worth, and forms new environment pollution.Existing cast iron rainwater pipe complex structure, weight is big, and ton product pipeline installation is short, and is manual sand casting, and the outward appearance sight is poor, and is extremely unbecoming with the modern high-rise building thing.
Existing rainwater pipe simpler structure by straight tube, bellmouth position and fixedly ear form, fixedly ear on straight tube, is distributed with two pairs not at the bellmouth position, installs inconvenience relatively.The wall covering surface of whole rainwater pipe is a flat face, has increased weight, and consumptive material is many.Bellmouth position intensity is lower, and tube and tube is tighter when connecting, and during a certain vibrations, can influence other pipe.The profile sight is poor.
The utility model provides a kind of rainwater pipe, and designs simplification is in light weight, long service life, good looking appearance.
Rainwater pipe of the present utility model comprises straight tube, bellmouth body, fixing ear, fixedly on the ear fixing hole is arranged, and fixedly ear is respectively in the both sides of bellmouth body to it is characterized in that two, and the protruding wall face portion of bellmouth body has reinforcing rib.
Described bellmouth body epirelief goes out metope and partly is preferably in it and up and down laterally reinforcing rib is respectively arranged together two ends.
In order to improve the fixedly intensity of ear position, reinforcing rib is connected with fixing ear.
The utility model has only two fixedly ears, and is easy for installation, alleviated weight: the faucet part bit strip has reinforcing rib and may extend into fixedly that ear has strengthened the intensity at this position, and the wall covering surface of bellmouth body can hollow out, and saves material, weight reduction.Straight tube, bellmouth body, fixedly ear can be the integral structure component that forms with the metal die continuous casting.
Straight tube end of the present utility model is the socket end, and when tube and tube connected, wherein one straight tube inserted in the bellmouth body of another root, and the wall covering surface of bellmouth body is the plane, and its internal diameter is slightly larger than the straight tube external diameter.The comparison pine that can install between tube and tube like this, during certain root rainwater pipe vibrations, adjacent rainwater pipe is unaffected.
The protruding wall face portion of bellmouth body of the present utility model is preferably convex globoidal, and straight tube is preferably cylindrical tube.Straight tube also can be other shape, and as square etc., the internal diameter of bellmouth body is corresponding shape, cooperates.
Below in conjunction with the embodiment description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A view of Fig. 1.
Among the figure: 1 straight tube, 2 bellmouth bodys 3 are ear 4 fixing holes 5 reinforcing ribs 6 cavitys 7 wall covering surfaces fixedly
Fig. 1 is two structural representations that cast iron rainwater pipe is installed together, and straight tube 1 end of rainwater pipe is inserted in the bellmouth body 2 of another rainwater pipe, and the internal diameter of bellmouth body is slightly larger than the straight tube external diameter, leaves appropriate gap betwixt, can be between 2～5 millimeters.Two reinforcing ribs 5 are arranged on the bellmouth body 2 and extend to fixedly 3 ones in ear, straight tube 1 is a cylinder, and the part of the protrusion metope of bellmouth body is a convex globoidal, and its wall covering surface 7 is a flat face, and there is a cavity 6 middle part.
The external surface of straight tube and bellmouth body junction has tangible step, and the gap has 2～3 millimeters.
Integral product adopts the metal die continuous casting to form cast iron rainwater pipe, dense structure's height, and wall thickness is even.
Fix with metope by screw etc. by the fixing hole on the fixing ear, be connected together by many rainwater pipe boxes.
Advantage of the present utility model:
Simple in structure, save material, in light weight, the intensity height is in structure with install more easy. Integral product can The continuous casting of employing metal die, dense structure's height, wall thickness is even, has good anti-rainwater corrosive nature, does not have aging Denaturalization phenomenon, long service life, it is fragile fundamentally to have solved existing rain pipe, the difficult problem that service life is short. Fire prevention, Good to weather temperature difference adaptability. The tensile strength of cast iron rainwater pipe is greater than 150Mpa, and the body flexibility is less than 2mm/m. It is very convenient to install, the splicing position Nature Link, and leave appropriate gap, have good shock resistance. Outside the utility model Shape is attractive in appearance, meets the requirement of modern high-rise building.
