Description

Flat-opening type drainage floor drain structure without water seal

Technical Field

The utility model relates to a flat-mouth type drainage floor drain structure that can be used to include but not be limited to zero board of falling of building and not have the water seal in with layer drainage.

Background

In the building construction, adopt the structure of zero board that falls to departments such as bathroom, can have that construction cost is low, and construction period is short, and the floor board is unanimous with other room floor board heights to it is higher to bring bathroom floor board structural strength, and the zero board structure that falls of bathroom is through the space height that can effectively strengthen the bathroom, has also improved multifaceted advantages such as people's residence space comfort. At present, in the floor plate zero-falling plate structure of a building toilet, a common water seal is arranged in a drainage collector, namely, waste water discharged by drainage parts such as a washbasin, a bathtub, a floor drain and the like is not separately arranged, but the common water seal structure is uniformly arranged at the position of the waste water collector to avoid overflowing of dirty air. Therefore, the existing drainage floor drain body adopts a non-water seal floor drain. Although the traditional flat-mouth type water seal-free drainage floor drain has the advantages of convenience and convenience in construction, the waterproof layer at the edge of the floor drain is easy to construct, the leakage of wastewater from the edge of the floor drain after waterproof construction is easily prevented, and the integral decorative aesthetic effect is better after toilet decoration and flat-mouth floor drain installation. In the construction of the zero-drop board same-layer drainage of the building, the total thickness of the cushion layer on the upper plane of the floor board and the decorative layers such as the ceramic tiles and the like on the upper plane of the floor board is about 50-60mm, and the diameter of the horizontal branch pipe for the drainage water, which is laid in the cushion layer below the decorative layers such as the ceramic tiles and the like and connected with the drainage collector, is generally 50 mm. However, the traditional flat-mouth water-seal-free floor drain with the total height of 50-60mm is restricted by the requirements of relevant building construction standards and specifications on the pipe diameter of the waste water discharge cross pipe to be not less than dn50 and the mandatory requirement that the waste water discharge cross pipe needs to be provided with a gradient of 2.5 percent, and the traditional flat-mouth water-seal-free floor drain has the height requirement that the flat-mouth water-seal-free floor drain is difficult to directly install and fix on the upper plane of a blank floor slab on the premise that the slab of the blank floor slab does not fall.

Therefore, the floor drain with the same layer of drainage, which is provided in the Chinese patent publication No. CN1932173A, has a water flow channel in a flat and long shape, a tail part of the water flow channel is converted into a round water outlet pipe section, and the middle part of the water flow channel is in a smooth transition form. Usually, the floor drain needs to be arranged at a distance of about 30mm from the wall surface, the circular outlet pipe of the floor drain of the prolate water flow channel can only extend into the pipeline well, a water seal deodorization elbow such as a P-shaped trap or a U-shaped elbow and the like needs to be arranged in the pipeline well, and a vertical drainage pipe fixedly arranged in the pipeline well and an exhaust pipe possibly arranged at the same time need to be avoided. Since the space size in the conventional standard pipe well is 420x240mm, the length of the water flow channel in the flat and long shape, the length of the smooth transition section in the middle part and the total length of the tail part converted into the circular water outlet pipe section are too long, so that the space size in the conventional pipe well of the toilet when the zero drop plate is used is difficult to accommodate the circular water outlet pipe section and the water seal deodorization elbow which extend into the pipe well. Therefore, the inner space of the pipe shaft can only be enlarged, and the limited indoor use space becomes smaller. In addition, if the floor drain far away from the pipe shaft still adopts the prolate water flow channel, the flow speed of water in the prolate water flow channel can be greatly reduced, solid matters in the water flow are easy to deposit to form blockage, and blockage removal and dredging are very difficult. And the gradually narrowed smooth transition section from the flat and long channel to the tail circular water outlet pipe section can cause effective water flow path, and the requirement that the drainage flow rate specified by CJ/T186-2018 floor drain standard is not less than 0.6L/s is difficult to meet.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention provides a flat type floor drain structure without water seal, which can be used in the same floor drainage including but not limited to the zero-drop floor of a building, and can solve the above problems well.

The utility model discloses a no water seal flat mouth type drainage floor drain structure, basic structure include that the ground opening at the floor drain body is equipped with flat mouth type water filtering grate, and its below is equipped with turns to the rivers passageway that communicates to far-end export and waste water discharge pipe way and be connected. The water flow channel is a channel structure with a variable diameter or different diameter form, the axial length of the water flow channel in the water flow direction is less than the width of the radial inner diameter vertical to the water flow direction, and the height of the radial inner diameter vertical to the water flow direction is less than the radial width. A transition communicating section with gradually changed pipe diameter adaptability is arranged between a passage outlet behind the water flow passage and a conventional circular interface structure used for connecting a waste water discharge pipeline.

In the above-mentioned structure, owing to shortened the ascending axial length of rivers passageway rivers direction as far as possible, can effectively realize being difficult for in the rivers passageway precipitating the solid of mixing in waste water, even if have the solid of a small amount of precipitations in the rivers passageway, also can more conveniently clean the mediation. In addition, to far away being close to the floor drain structure of vertical wall setting apart from the piping shaft, the process is shorter the length that transition intercommunication section lug connection's conventional circular interface stretched into the waste water drainage pipeline corridor in the decorative wall is very short, can effectively realize the width minimizing of waste water drainage pipeline corridor, and then reduces the purpose of shielding blowdown waste water pipeline decorative wall gross thickness to be favorable to the effective usage space total thickness of maximize increase bathroom

In order to better ensure and even enlarge the effective water flow path of the water flow channel in the form of reducing or reducing in the structure, the radial width of the inner diameter of the water flow channel can be better made to be larger than that of the conventional circular interface structure. On the basis that the water flow channel is in the flat tube structure with the radial inner diameter height perpendicular to the water flow direction smaller than the radial width, the radial width of the inner diameter of the water flow channel is larger than the inner diameter of the conventional circular interface structure, obviously, the transverse diameter of the water flow channel can be further widened, and therefore the effective diameter area of the water flow channel is enlarged, the water flow channel not only can meet the drainage flow requirement specified by the corresponding standard, but also can well adapt to the sudden instantaneous large water flow condition.

In addition, a water guide space with a convex pipe diameter and an enlarged water guide space can be arranged above the transition communication section between the water flow channel and the conventional circular interface structure, so that the water guide space is further favorable for improving the water flow passing capacity, and particularly when large water flow passes instantaneously, the situation of local clogging is avoided, so that the channel is more smooth and unobstructed.

In order to avoid larger solid matters which easily cause pipeline blockage from the source from entering the water flow channel, on the basis of the drainage floor drain with the structure, a structure with proper filter meshes and a filter screen can be arranged between the water filtering grate and the water flow channel.

According to the construction requirement, a plane-outward-extending waterproof structure with a proper expansion shape/area can be arranged below the floor drain body. In particular, the surface of the waterproof structure can be provided with concave-convex structures in proper forms such as grooves and/or ribs which can increase the surface area of the waterproof structure, so that the adhesion reliability of the waterproof structure laid during construction is improved.

For the purpose of facilitating construction and improving construction quality, a fixed connecting structure in a proper form such as a connecting lug for positioning and fixing with the construction surface can be arranged outside the bottom surface of the floor drain body independently or in combination with the structure.

Test results show that according to the design of the drainage floor drain structure, an optimized structure form is that the height difference of the outer wall at the top of the water flow channel, which is lower than the outer wall at the top of the conventional circular connector structure, is at least 10mm, and/or the height difference of the outer wall at the top of the water flow channel, which is lower than the upper plane of the water filtering grate, is at least 10mm, so that the drainage floor drain structure is more ideal, not only can better adapt to and meet the characteristics and the requirements of drainage of a zero-fall board of a building on the same floor on the premise of ensuring the smoothness and the non-resistance of the water flow channel, but also can satisfactorily lay waterproof paint around the surface layer of the floor drain, particularly above the top outer wall of a water flow channel pipe, lay a mortar combination layer above the paint, and lay a.

Therefore, the utility model discloses above-mentioned structural style's no water seal flat mouth type drainage floor drain structure can give consideration to the characteristics and the needs of zero board with layer drainage of falling of building satisfactorily to and the construction of normal floor drain and the needs of drainage flow under the general condition or special circumstances, especially solved including publication CN1932173A etc. and in the present existing drainage floor drain structure of the same kind not can satisfy not enough and the problem of solution yet
