Description
Technical Field
The utility model relates to a floor drainage equipment technical field specifically is a pre-buried formula cast iron is with layer drainage connecting device.
Background
The drainage system on the same floor is a drainage system which is applied and popularized in the market at present, and the system generally adopts a pipeline and a pipe fitting device made of PVC materials. In order to prevent water impact force caused by high fall, the super high-rise building adopts safe and reliable cast iron drainage pipes and pipe fittings.
In modern building construction, in order to facilitate installation of the drainage vertical pipe, holes are reserved at corresponding positions of a floor slab in the construction process. After the vertical pipe is installed, the reserved hole is plugged with fine stone concrete twice. Such construction consumes a lot of manpower and material resources, and not only the construction period is long, but also the phenomenon of water leakage is easy to occur.
The cast iron same-layer drainage connecting device in the current market is a drainage system without lowering a plate, and when a toilet is designed to be used for lowering the plate and draining water at the same layer, the existing cast iron product design cannot meet the requirement of draining accumulated water in a caisson.
Because of the different materials, the iron casting generally adopts the spigot-and-socket connection and the flange connection, and the PVC drainage piece generally adopts the glue bonding and the sealing rubber ring connection. Due to different connection modes, the embedded iron casting needs to be different from a PVC embedded part in the structural design of the embedded iron casting, so that the functional requirements are met, and the connection requirements can be met.
Disclosure of Invention
An object of the utility model is to provide a pre-buried formula cast iron is with layer drainage connecting device to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a pre-buried cast iron same-layer drainage connecting device comprises: pre-buried connecting piece main part, flange, big eccentric pipe, little eccentric pipe, big sealing washer, little sealing washer, pre-buried connecting piece main part be hollow tubular structure, flange setting at the lower extreme of pre-buried connecting piece main part, flange and pre-buried connecting piece main part link into an integrated entity when production, flange and iron casting main riser carry out flange joint, the big eccentric lower extreme ladder mouth of big eccentric pipe be connected with pre-buried connecting piece main part through big sealing washer, the little eccentric lower extreme ladder mouth of little eccentric pipe be connected with big eccentric pipe upper end through little sealing washer.
Furthermore, the small eccentric upper end stepped port of the small eccentric pipe is connected with the PVC main vertical pipe through a sealing ring.
Furthermore, a groove for placing a sealing rubber pad is arranged on the inner side of the connecting flange.
Furthermore, the middle part of the connecting flange is provided with a threaded hole for fixing a standard flange.
Furthermore, the edge of the connecting flange is provided with a fixing hole for fixing a product to be installed.
Furthermore, concave-convex parts used for controlling the distance are arranged on the side faces of the connecting flanges.
Furthermore, a plurality of water drainage holes are designed on the large eccentric pipe.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a method that big eccentric pipe and little eccentric pipe are dual sets up is adopted, can freely rotate, adjusts the eccentric distance of main riser installation through two-way regulation, even if one of them riser takes place the skew in two adjacent floors, does not also influence the installation of riser, convenient operation;
2. the large eccentric pipe and the small eccentric pipe of the utility model are provided with a plurality of drain holes, and the accumulated water in the caisson can be discharged into the main vertical pipe through the drain holes, thereby preventing the accumulated water in the caisson from leaking;
3. the utility model discloses a flange accessible flange joint cast iron pipeline, and little eccentric upper end notch ladder accessible sealing washer and PVC pipe connection.
The utility model has the advantages of simple structure, firm connection, convenient installation and the like.
