Abstract

The utility model relates to a connecting piece for the connecting part of the cast iron water discharge pipelines of the high-rise buildings and industrial factory buildings, comprising a socket pipe and a telescoping pipe. The inner diameter of the outer opening of the socket pipe is matched with the outer diameter of the upper opening of the water drainage pipe. The outer diameter of the inner opening of the socket pipe and the inner diameter of the inner opening of the telescopic pipe are matched and sheathed into a whole, and are provided with sealing rubber rings. The outer diameter of the outer opening of the telescopic pipe is matched with the inner diameter of the lower opening of the water discharge pipeline. The outer end of the outer opening of the socket pipe is connected with a fixing support seat which is fixedly connected with the corresponding position of the wall.

Description

Iron drain-pipe spigot and socket type expansion bend

The utility model relates to the link of iron drain-pipe joint in a kind of tall building and the industrial premises.

Iron drain-pipe road in existing tall building and the industrial premises adopts cement bayonet joint mouth mostly in the joint, this linkage structure does not have stretchability, does not have shock resistance and flexibility yet, and noise is big, yielding fracture and water leakage phenomenon occurs.And this cement spigot and socket type interface need use angle steel support or other support to fix, consumption expenses of labour material, and labor intensity is big, the cost height.In addition, the structure that also has minority unit to adopt rubber ring and flange to be fastenedly connected in the joint in iron drain-pipe road constitutes antidetonation flexible water drainage pipe.But this linkage structure cost costliness is time-consuming, and inconvenience is installed, can't the large size penetration and promotion.

The purpose of this utility model is exactly to provide a kind of cost low in order to address the above problem, and flexible shock resistance is good, labor and material saving and be easy to the iron drain-pipe spigot and socket type expansion bend of penetration and promotion.

Technical solution of the present utility model:

A kind of iron drain-pipe spigot and socket type expansion bend, it is characterized in that it is made up of bell-and-spigot pipe (1) and telescopic pipe (2), bell-and-spigot pipe (1) collar extension internal diameter and iron drain-pipe road external diameter suitable for reading matches, and connect as one with spigot and socket type cement, bell-and-spigot pipe (1) internal orifice external diameter and telescopic pipe (2) internal orifice internal diameter match and the socket that coincide is an one, be provided with sealing rubber ring (3) between them, with water leakage, telescopic pipe (2) collar extension external diameter and iron drain-pipe road end opening internal diameter match, also adopt spigot and socket type cement to connect as one, outer end, bell-and-spigot pipe (1) collar extension place is connected with fixed bearing (4), to fixedly connected with the body of wall corresponding position.

The utility model adopts telescopic linkage structure first, make the function of the existing flexible water drainage pipeline in iron drain-pipe road, reduce engineering cost again, save a large amount of artificial and angle steel materials, thoroughly solved problems such as the no elasticity of plain cast iron drainage pipe, yielding fracture are in the past leaked and shock resistance is poor, noise is big.The utility model is simple in structure, and performance is good, and itself has base, can directly be connected with body of wall to save a large amount of angle steel supports, and cost reduces greatly, but the large size penetration and promotion.Flexible ability of the present utility model is 1-3cm, and bearing induced pressure is one ton, and bearing pressure in the pipe when meeting obstruction as pipeline is 3Kg/cm ²

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

Fig. 2 is that the A of Fig. 1 is to view.

As Fig. 1,2, when the utility model uses, with bell-and-spigot pipe (1) collar extension and the iron drain-pipe road is suitable for reading is connected as a single entity, its internal orifice and telescopic pipe (2) internal orifice are connected as a single entity, the collar extension of telescopic pipe (2) and iron drain-pipe road end opening are connected as a single entity, and the fixed bearing (4) of bell-and-spigot pipe (1) firmly is connected on the body of wall by setscrew, usually every three floor positions an expansion bend of the present utility model is set, also can increase according to actual needs or reduce, thereby the iron drain-pipe road of whole tall building is linked to be integral body.The function of the existing flexible water drainage pipe of iron drain-pipe has reduced engineering cost again like this, has saved a large amount of artificial and angle steel materials, has thoroughly solved the sequelae that portland cement spigot and socket type waste pipe is brought, and effect is very good.
