Same-floor drainage system of toilet without slab lowering

Abstract

The invention provides a same-floor drainage system of a toilet without slab lowering. The same-floor drainage system of the toilet without slab lowering is composed of a drainage vertical pipe, a sewage transverse branch pipe, a waste water transverse branch pipe, an integrated water seal, a floor drain, a ground floor slab and a floor decoration layer; the drainage vertical pipe penetrates through the ground floor slab; a water seal channel of the integrated water seal is arranged in a ground floor slab, the transversely-closed bottom outer wall does not penetrate through the ground floor slab; at least two openings, of the integrated water seal, above the ground floor slab communicate with and are converged to be connected with the water seal channel; and a waste water transverse branchpipe connector is connected with the floor drain and a wash basin pipeline, and the floor drain and the wash basin pipeline are not provided with traps or water seal devices. According to the same-floor drainage system of the toilet without slab lowering, the problems that a floor slab needs to be lowered during same-floor drainage of a traditional building, the traps which are arranged below alldrainage points are prone to drying up to cause odor return can be solved, and the effects that same-floor drainage does not need slab lowering, a toilet does not have peculiar smells, and the pipeline is easy to overhaul are achieved.

Description

technical field [0001] The invention relates to a same-floor drainage system for buildings, in particular to a same-floor drainage system for toilets without lowering boards. Background technique [0002] Bathrooms in traditional buildings are drained on the same floor. Due to the layout of drainage pipes, the building structure needs to be lowered to the floor. The height of the lowered slab is large (mostly about 300mm). They are all set separately, so that the water seals of infrequently used appliances are easy to dry up, and the bathroom is easy to produce peculiar smell. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a bathroom that drains water on the same floor of the building. It does not need to lower the floor of the building structure or reduce the height of the floor. It is a kind of drainage system on the same floor of the building that produces peculiar smell and is easy to re...
