Description
Technical Field
The utility model belongs to the technical field of building drainage system technique and specifically relates to a novel drainage system's extending structure is related to.
Background
In drainage engineering in civil engineering, the problem of expansion and contraction of a drainage pipe (mainly made of PVC materials) is often involved, and the expansion and contraction of the drainage pipe are adjusted through a threaded expansion joint in the prior art or through a similar structure of the threaded expansion joint. In field construction, the wire expansion joint is also often used in the construction of repairing the drain pipe.
In the construction of the drainage vertical pipe, two forms are provided, one is to use a pre-embedded part for construction, and the other is to use no pre-embedded part to construct the drainage pipe from bottom to top. According to the specification, the vertical pipe is more than 4 meters, and a telescopic joint must be arranged. At present, the drainage fitting with a telescopic function integrates the original function and the telescopic function into a whole.
In any construction method, the telescopic member is of a similar telescopic structure, but the structure has the following problems in the construction and maintenance process:
1. when the expansion joint with the wire is constructed, the sealing cover, the limiting ring and the sealing ring need to be detached; when the device is installed, the limiting ring and the sealing ring are sleeved, and the sealing cover is tightened. After the drain pipe is sleeved by the sealing ring, the sealing ring needs to be plugged into the expansion joint, and the bottom needs to be plugged, otherwise, the sealing cover is difficult to tighten. When the sealing cover is arranged, the screw teeth of the sealing cover are staggered, so that the sealing cover is not compact, and the appearance is influenced. Especially, the pipe body is too close to the wall body, and the construction is more difficult.
2. When the vertical pipe is installed by using the embedded part, impurities such as dust, sand grains and mortar easily enter the expansion joint (or accessories with expansion function), so that the installation of the sealing ring is troublesome, the installation of the sealing cover on the expansion joint is difficult, the installation is not tight, and the expansion effect and the attractiveness are influenced.
3. The drain pipe without the embedded part is installed, and the common drain pipe is installed from bottom to top. Due to the action of gravity, the clearance of the pipe inserted into the expansion joint does not necessarily guarantee the specification or design requirements.
4. To the accessory that uses extending structure at both ends, in the installation, tighten sealing washer, limit ring and sealed lid, comparatively take a lot of trouble. Especially, it is troublesome to plug up the sealing washer that is close to the wall corner, influences whole installation quality and effect easily.
5. The outer wall drain pipe is often sprayed paint, and the sealed lid of telescopic joint and inside are easily flowed into liquid coating, wait that the coating solidifies the back, are difficult to lift, are not convenient for maintain.
6. Glue is dripped into the telescopic joint (or the fittings with the telescopic function), which is not beneficial to the extension of the pipe body.
7. The telescopic joint (or the accessory with the telescopic function) has no scale indication, the construction randomness is large, the telescopic quantity is inconvenient to look over in acceptance check, the telescopic joint can not act, and the deformation of the drain pipe occurs.
8. The radius of the sealing ring cover opening of the telescopic joint (or the accessory with the telescopic function) is greatly different from that of the pipe body, and the streamline aesthetic feeling is avoided.
9. During maintenance, the original telescopic joint (or the accessory with the telescopic function) is cut, the operation is difficult, and the pipe body can be cut, so that more maintenance cost is brought.
