Description

Double-layer rotatable embedded floor drain

Technical Field

The utility model relates to a double-deck rotatable pre-buried floor drain for floor ponding is got rid of in the construction stage, belongs to the pre-buried pipe fitting technical field of building.

Background

The floor drain is most prone to blockage in the construction stage, the floor drain construction stage relates to alternate construction of a hydropower team and a civil engineering team, and the difficulty in protecting the finished product of the floor drain is undoubtedly increased due to different work types of construction operation; once the floor drain is blocked, the consequence is that the whole water pipe connected with the floor drain needs to be replaced again, so that the manpower, material resources and financial resources are wasted, the most important is the delay of the construction period, and in order to ensure the construction period, the smooth connection of all working procedures and the survival at one time are the most important. However, due to the fact that the difficulty of site construction management is high, various kinds of cross work are more, and the fact that the workers have different protection consciousness results in that a lot of floor drains are blocked on site after houses are delivered to owners, the problem that floor drain pipelines are blocked in the construction stage is met with more urgent need.

The main reasons for causing the floor drain to be blocked are as follows: 1. before concrete is poured, the damage of the pipeline cover causes the concrete and sundries to flow into the pipeline to cause blockage; 2. after the floor slab is poured, the floor surface is chiseled and cleaned after the indoor masonry, the secondary structure and the plastering decoration are finished, and finally the floor surface is poured with the leveling mortar, so that the pipeline is blocked by the pipeline cover when the floor surface is leveled; 3. after concrete pouring is finished, the floor drain pipeline is usually higher than the finished surface of a structure by a few centimeters, rainwater on balconies, terraces and the like cannot be discharged along the floor drain pipeline after heavy rainfall due to the fact that the height of the floor drain pipeline is a few centimeters, workers can cut the side surface of the pipeline or directly damage the pipeline to discharge the rainwater due to the fact that workers need to conduct construction on the floor and the teams and groups for indoor decoration, and therefore sundries and mortar on the balcony can flow into the pipeline to cause blockage when the mortar is found on the ground.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problem, the utility model provides a double-deck rotatable pre-buried floor drain has increased rotatable recovery formula interior conduit, solves building ground construction stage ponding and gets rid of the problem, and debris jam pipeline can be avoided to the bottom filter screen of double-deck rotatable pre-buried floor drain, and the cost can be practiced thrift to recovery formula interior conduit on economic benefits.

The technical scheme of the utility model as follows:

a double-layer rotatable pre-buried floor drain comprises an outer pipeline, an inner pipeline and a floor drain cover; the inner pipeline is sleeved in the outer pipeline and can rotate along the inner side wall of the outer pipeline; the floor drain cover is arranged at the top of the outer pipeline, and the inside of the floor drain cover is in a mesh hollow shape; an end clamping ring is arranged on the outer ring of the top of the inner pipeline, and the diameter of the end clamping ring is larger than the outer diameter of the outer pipeline; the side wall of the outer pipeline is provided with a vertical outer pipeline water falling groove; the side wall of the inner pipeline is provided with a vertical inner pipeline water falling groove.

Further, the inner pipeline and the outer pipeline are both vertically through hollow pipelines; and a filter screen is arranged at the bottom of the inner pipeline.

Further, the outer pipeline downpipe groove and the inner pipeline downpipe groove have the same size; the height of the outer pipeline water falling groove and the height of the inner pipeline water falling groove in the vertical direction are the same as the thickness of the building leveling layer, and the height of the outer pipeline water falling groove and the height of the inner pipeline water falling groove are 20-25 mm.

Furthermore, the bottom of the outer pipeline water falling groove and the elevation of the floor slab structure are located at the same position.

The utility model discloses following beneficial effect has: the double-layer rotatable pre-buried floor drain is convenient for draining accumulated water of a floor slab in a construction stage, the rotatable inner pipeline is added on the basis of a single pipeline to form a double-layer pipeline, meanwhile, the inner pipeline water falling groove and the outer pipeline water falling groove are formed in the side walls of the inner pipeline and the outer pipeline, the problem of draining accumulated water in the floor construction stage can be solved by the superposition of the two water falling grooves, and the construction period is saved; later floor drain plugging and water seepage maintenance are avoided, and cost is saved; the filter screen is arranged at the bottom of the inner pipeline to prevent sundries from blocking the pipeline, and meanwhile, the inner pipeline can be pulled out for recovery and replacement, so that the device is convenient to disassemble and assemble and simple to operate.

Detailed Description

A double-layer rotatable pre-buried floor drain is convenient for draining floor accumulated water in a construction stage and comprises an outer pipeline 1, an inner pipeline 2 and a floor drain cover 3; the inner pipeline 2 is sleeved inside the outer pipeline 1 and can rotate along the inner side wall of the outer pipeline 1 to form a double-layer rotatable pipeline; the floor drain cover 3 is arranged at the top of the outer pipeline 1, the inside of the floor drain cover 3 is in a mesh hollow shape, and the floor drain cover 3 is made of plastic materials with good elasticity and can be buckled on the outer pipeline 1; an end clamping ring 4 is arranged on the outer ring of the top of the inner pipeline 2, the diameter of the end clamping ring 4 is larger than the outer diameter of the outer pipeline 1, and the end clamping ring 4 is used for fixing the inner pipeline 2 to prevent the inner pipeline 2 from falling into the outer pipeline 1; the side wall of the outer pipeline 1 is provided with a vertical outer pipeline water falling groove 5; the side wall of the inner pipeline 2 is provided with a vertical inner pipeline water falling groove 6, the inner pipeline 2 is rotated to enable the inner side wall of the outer pipeline 1 to rotate, and at the moment, the outer pipeline water falling groove 5 and the inner pipeline water falling groove 6 can be overlapped for drainage.
