Abstract

FIELD: building, particularly sanitary equipment for receiving and removing sewage water from floor surface into sewage system.

SUBSTANCE: device has cylindrical body, outlet connection pipe, cylindrical hydraulic lock, falcate channel for liquid and grate. Body has regular cylindrical surface without any extensions on side surface. Vertical outlet channel of body is offset towards rear body wall. Horizontal part of removable outlet connection pipe with connection thread is located under semispherical body bottom and does not extend beyond body periphery. Outlet channel of body and vertical end of outlet connection pipe have common control-and-connection screw thread.

Description

The invention relates to the construction and, in particular, to sanitary equipment for receiving and removing wastewater from the floor surface into the sewer system.

Known devices for receiving and removing wastewater from the surface of the floor into the sewer system, having a housing with a partition and a hole for cleaning, an outlet pipe of a lateral location with a protrusion beyond the side wall and grille [1].

A device with a cylindrical body, a cylindrical hydraulic seal and a Central vertical outlet [2].

The closest analogue is a device for receiving and removing wastewater, including a cylindrical body, an exhaust pipe, a cylindrical water seal, a sickle-shaped channel for the passage of fluid and a grill [3].

However, all these devices, including the closest analogue, do not have sufficient installation adaptability for:

- mechanized preparation of the installation site in the concrete floor;

- reliable waterproofing of the case due to the complex external configuration and the absence of sealing devices on them;

- achieving removability of the housing due to protruding parts beyond the side surface.

The height of the outlet pipe is regulated only in [2], where the pipe is docked with the exhaust channel in a closed concrete floor and does not guarantee against leakage from thermal expansion. In addition, a major drawback of the known devices is the impossibility of a threaded connection of their release with a discharge pipe passing through places that are closed for the plumber both under the floor of rooms without a basement, and in hollow channels of building structures.

The aim of the invention is the provision of mechanized preparation of holes in the concrete floor for the housing of the device, increasing the reliability of the sealing of the housing with the concrete floor, achieving removability of the device, socket-screw connection of the outlet pipe to the discharge pipe, adjustable height of the outlet.

These goals are achieved by the fact that in the device for receiving and removing wastewater, including a cylindrical body, an exhaust pipe, a cylindrical water seal, a crescent-shaped channel for the passage of fluid and a grill, the body is made of the correct cylindrical shape, without protrusions of parts on the side surface, the vertical output channel of the body offset to its rear wall, and the horizontal part of the removable exhaust pipe with a connecting thread is placed under the hemispherical bottom of the housing, without going beyond it. In this case, the outlet channel of the housing and the vertical end of the exhaust pipe have a common connecting and adjusting screw thread.

Figure 1 shows the right view of the proposed device, and figure 2 is a top view of the same device without a grill.

The device comprises a cylindrical housing 1, a removable water seal 2, a removable exhaust pipe 3 with a connecting and high-adjustment screw thread 4 and its upper end with a lock nut 5, and its horizontal end is also equipped with a connecting screw thread 6 and is placed under the hemispherical bottom 7 of the housing without going beyond its limits, the landing waist collar 8 has sealing risks 9, the grill 10 closes the housing from above. For the socket-screw connection of the exhaust pipe with the outlet pipe 11, a coupling pipe 12 is used, an elastic sealing washer 13 is located under the landing collar 8, the housing 1 and the lock nut 5 are sealed with a gasket 14.

The device is mounted as follows. First, the height of the outlet pipe 3 is determined by the floor thickness or the diameter of the channel of the hollow building structure, then the excess part of the thread is cut off at the upper end of this pipe, after which it is screwed into the outlet channel of the housing 1 and fixed with a lock nut 5 with gasket 14, then a hole for installing a cylindrical hole is drilled casing 1 in a concrete floor mechanized by a portable drilling machine, for example IE 1801 with a standard ring drill 108 or 132, respectively, for pipelines Δ _y - 50 mm and Δ _y - 100 mm, then the housing 1 of the device under the shoulder 8 is put on tight by an elastic washer 13, the surface of the housing is preliminarily lubricated with a viscous waterproofing mastic, and firmly lowered into the floor hole until the shoulder stops in the waterproofing floor mat / the rug is not shown /, after which the outlet pipe 3 has a smooth straight horizontal turn and a connecting screw thread 6, by displacing it to the rear wall of the housing 1, is easily connected to the discharge pipe 11 by a screw thread using a sleeve 12, as shown in FIG. 1, then to connect the sewer pipelines 11 to each other in closed concrete channels, a sleeve-pipe 12 or conventional connecting fittings for pressure pipelines made of anticorrosive material are used, and at the same time, the slope of the pipes is up to 2ψ2.5% on average due to the limited drop in the channels. To achieve coaxiality of the outlet pipe with the outlet pipe, the first one has a downward slope of 1.5ψ2 degrees, to facilitate blind blind joining and screwing them in places that are inaccessible to the plumber and hollow ducts of the building structure, the edges of the outlet pipe end face are chamfered to the center, and outside the coupling sleeve, .

An additional increase in the reliability of sealing the case with a concrete floor is achieved by the fact that an elastic washer 13 with an outer diameter larger than that of the shoulder is tightly put on the cylindrical body under the shoulder 8.

The manufacture and installation of an experimental sample of the proposed device can simultaneously provide:

- mechanized preparation of holes in the concrete floor for installation;

- removable housing;

- reliable housing seal with concrete floor;

- the displacement of the outlet channel to the rear wall of the housing makes it possible to have, within its diameter, a smooth horizontal rotation of the nozzle with a straight helical path at its end for threaded connection with the outlet pipe;

- the presence in the outlet channel of the housing and at the vertical end of the outlet pipe of a common connecting and adjusting thread allows you to adjust the height of the outlet pipe;

- the transfer of an open suspended sewer pipe from the ceiling to the hollow channel of the floor slab significantly improves the aesthetics of the room.
