Detailed Description

The following is a specific embodiment of the present utility model, and the technical solution of the present utility model is further described with reference to the accompanying drawings, but the present utility model is not limited to these examples.

As shown in fig. 1 and 2, the secondary drainage waterproof bottom box is arranged on a floor structure 1 of a toilet or other space with drainage requirement, and the waterproof bottom box is used for guiding water on the floor structure 1 into a sewer structure 2 of a building, wherein the sewer structure 2 is generally referred to as a sewer pipeline.

As shown in fig. 2, in this application, floor structure 1 erects in original ground top through the mounting bracket, and the mounting bracket includes the board of accepting that is unanimous basically with original ground area, accepts to connect through a plurality of support columns between board and the original ground, and the height of every support column can be adjusted alone, through the height of adjusting different support columns, can with accepting the board adjustment to the level, guarantees the level of follow-up floor structure 1. The specific height-adjustable support column structure can be various, such as an outer cylinder, an inner cylinder and the like which are connected through threads, and any one of the prior art can be adopted. An installation gap is formed between the receiving plate and the original ground, and the inlet of the sewage structure 2 is arranged in the installation gap. In order to avoid the upward odor of the sewage structure 2, the sewer pipe of the sewage structure 2 in this embodiment is horizontally disposed in the installation gap, so as to provide a buffer space for the gas to escape. The floor structure 1 sequentially comprises a waterproof layer 11, a connecting layer 12 and a floor tile layer 13 from bottom to top, wherein the waterproof layer 11 is formed by solidifying waterproof paint painted on a receiving plate and can prevent water from penetrating to the receiving plate and then to the original ground; the connecting layer 12 is generally cement, and is used for installing the floor tile layer 13, and the floor tile layer 13 is formed by splicing a plurality of ceramic tiles.

First of all with traditional waterproof end box unanimous, the waterproof end box of this application includes main drainage component 3, and main drainage component 3 is including running through in the main wash port of floor structure 1 and joint board, and the water on the floor structure 1 is through main wash port flow direction installation clearance, flow direction in the downthehole structure 2. In consideration of the problems of erosion of water to the side wall of the main drain hole and diversion of water flow in the flowing process, the main drain hole cannot be directly used, and a drain structure is usually arranged in the main drain hole. As shown in fig. 2, the drainage structure includes a sleeve 31, the axial direction of the sleeve 31 is parallel to the axial direction of the main drainage hole, the sleeve 31 is inserted into the main drainage hole, and the outer wall of the sleeve 31 is connected with the inner wall of the main drainage hole, and an actual drainage channel is formed in the sleeve 31, so that the sleeve 31 is preferably made of a material which is not easy to corrode and permeate water, such as a PVC pipe. The outer wall of the sleeve 31 is usually tightly connected with the material of the connecting layer 12 at the inner wall of the main drain hole, but in order to improve the installation strength of the sleeve 31 and avoid the sleeve 31 from falling off, in this embodiment, a convex mounting ring is arranged on the outer wall of the upper end of the sleeve 31, and the mounting ring can be further connected with the connecting layer 12 of the floor structure 1, so as to improve the contact area with the connecting layer 12. Meanwhile, the top of the mounting ring is preferably controlled to be abutted with the floor tile layer 13, so that the waterproof effect can be achieved to a certain extent: when gaps are formed between the floor tile layers 13 and the sleeves 31 and water seeps, if no mounting ring is arranged, water can directly seep downwards between the connecting layer 12 and the sleeves 31, so that corrosion is caused to the connecting layer 12; however, when the mounting ring is provided, water will fall onto the mounting ring when penetrating downwards, and water will be stopped from penetrating downwards. The sleeve 31 with the mounting ring is mounted as follows: firstly, installing a waterproof layer 11 and a connecting layer 12, and punching through holes at corresponding positions of the waterproof layer 11 and the connecting layer 12; digging a receiving groove at a position of the connecting layer 12 near the through hole, wherein the depth of the receiving groove is the same as the thickness of the mounting ring; inserting the sleeve 31 into the through hole, and inserting the mounting ring of the sleeve 31 into the receiving groove; and finally paving a ground brick layer 13 on the top of the connecting layer 12 and the top of the mounting ring, and simultaneously punching corresponding through holes in corresponding positions of the ground brick layer 13.

The upper opening of the sleeve 31 is flush with the top surface of the floor tile layer 13 or slightly lower than the top surface of the floor tile layer 13 to allow water to smoothly flow in, and a cover plate 32 is usually disposed at the upper opening, and the cover plate 32 is provided with a plurality of drain holes for draining water and preventing impurities with larger volume from entering the sleeve 31 to cause blockage. The cover plate 32 is preferably detachably connected to the sleeve 31 to facilitate cleaning of the cover plate 32 and the interior of the sleeve 31. For example, a boss may be provided on the inner wall of the sleeve 31, and the cover plate 32 is overlapped on the boss.

The axial length of the sleeve 31 is preferably greater than the length of the main drain hole so that the lower end opening of the sleeve 31 extends into the installation gap and communicates with the drain structure 2 for the flow of water to the drain structure 2. Considering that the drainage direction of the sleeve 31 is vertical and the drainage direction of the sewer structure 2 is horizontal, a steering conduit 33 is further arranged between the lower end opening of the sleeve 31 and the sewer structure 2, the steering conduit 33 is a pipe fitting with a horizontal axial direction, the top opening of the steering conduit is communicated with the lower end opening of the sleeve 31, and the axial pipe opening of the steering conduit is used for inserting the pipe fitting of the sewer structure 2.

In some cases, such as when the drainage of the drainage structure 2 is not in time and when the secondary drainage member 4 is used later, the influence on the drainage of the drainage structure 2 (which will be described later in detail) may be that the water of the drainage structure 2 flows in the reverse direction of the steering duct 33, and thus, a backflow prevention drain 34 is further provided in the steering duct 33, and as shown in fig. 4, the backflow prevention drain 34 includes a wide-mouth end and a narrow-mouth end, the outer wall of the wide-mouth end is connected with the inner wall of the sleeve 31, preferably in a detachable connection, such as a threaded connection, so as to be replaced, and the narrow-mouth end is suspended in the steering duct 33. The wide mouth end is a water inlet end, and the narrow mouth end is a water outlet end, so that when the backflow problem exists in the drainage structure 2, the narrow mouth end can stop the water flowing into the backflow prevention drain core 34 to a great extent. In order to further improve the anti-reflux effect, the narrow mouth end is preferably arranged to be lower, that is, the horizontal plane of the outlet of the narrow mouth end is not higher than the highest horizontal plane of the pipe orifice of the launching structure 2, so that the water flow mainly collides with the outer wall of the anti-reflux leakage core 34 during reflux, and is not easy to enter the outlet of the narrow mouth end.

Further, a water seal cylinder 331 is arranged in the steering conduit 33, the upper end of the water seal cylinder 331 is opened, the caliber is preferably larger than the inner diameter of the sleeve 31, the lower end of the water seal cylinder 331 is closed, meanwhile, the narrow opening end is inserted into the water seal cylinder 331, and an overflow gap is formed between the top end of the water seal cylinder 331 and the inner top of the steering conduit 33. In use, water flowing out of the anti-reflux leakage core 34 and water possibly leaking out of the sleeve 31 and the anti-reflux leakage core 34 due to loose connection flow into the water seal cylinder 331, and cannot flow out of the overflow port and then flow into the drainage structure 2 until the water seal cylinder 331 is filled. Therefore, the water seal cylinder 331 is always filled with water, and the narrow opening end is immersed in water, which forms a water seal for opening the narrow opening end, further avoiding the gas escaping from the sewage structure 2 from being deodorized by the main drainage member 3, and the cylinder wall of the water seal cylinder 331 further stops the water in the sewage structure 2 from flowing back towards the narrow opening end, so the cylinder height of the water seal cylinder 331 is preferably increased, and the cylinder height is larger than the caliber of the pipe orifice of the sewage structure 2.

Although the primary drainage member 3 may assist in draining most of the water, it may sometimes flow, spray in the direction of the wallboard, or condense and slide down after the water vapor adheres to the wallboard, which may result in water accumulation at the bottom of the wallboard. Therefore, secondly, the present application further includes a secondary drainage member 4 for assisting secondary drainage.

As shown in fig. 3, the secondary drainage member 4 includes a first baffle 41, a bottom plate 42, and a second baffle 43 connected in sequence, with a wall plate mounting groove formed between the first baffle 41, the bottom plate 42, and the second baffle 43. The first baffle 41 and the second baffle 43 are parallel and are all vertically arranged, the bottom plate 42 comprises a base layer section 421 and a supporting section 422 which are parallel, the horizontal plane of the supporting section 422 is lower than that of the base layer section 421, the supporting section 422 is connected with the base layer section 421 through a connecting section, and the connecting section is preferably vertically arranged. Based on this, when installing the wallboard, insert the wallboard bottom in the wallboard mounting groove, the front of control wallboard supports tightly with second baffle 43, can suitably fill some elastomer between the back of wallboard and the first baffle 41, the partly overlap joint of wallboard bottom is on basic unit section 421, another part is hung and is established on supporting section 422, form ponding recess 401 once between linkage segment, supporting section 422 and the first baffle 41, when having water infiltration to wallboard department, water can flow down, thereby gather in ponding recess 401 once, avoided the wallboard long-term with the contact of water.

To assist in draining water from the primary water accumulation groove 401, a secondary drain hole is provided in the support section 422, and the secondary drain hole communicates with the drain structure 2 through a connection pipe. Since both the primary and secondary drainage holes need to communicate with the drain structure 2, connecting the connection pipe, the turn conduit 33, and the drain structure 2 through the tee as shown in fig. 2 inevitably creates the above-mentioned reflux problem: when both the connecting pipe and the steering pipe 33 drain, the water inflow of the three-way pipe is large, but the pipe diameter of the outlet is unchanged, so that the problem of backflow caused by blocked drainage can exist; or when the connecting pipe needs to drain water and the steering conduit 33 does not need to drain water, the water of the connecting pipe has a tendency to flow in the direction of the steering conduit 33 after vertically falling; meanwhile, as the pipe diameter of the connecting pipe is smaller, the kinetic energy of water flow is larger, water bloom can be excited in the three-way pipe, and the water bloom can flow towards the direction of the steering guide pipe 33. Therefore, in the case where the secondary drain hole is provided, the primary drain member 3 is necessary to prevent backflow.

The connecting pipe is also preferably connected with the secondary drainage hole through a three-way pipe, a vertical pipe is arranged at the top of the three-way pipe, one end of the vertical pipe passes through the secondary drainage hole, and a lap joint ring is arranged on the outer wall of the vertical pipe so as to be lapped on the supporting section 422, the other end of the vertical pipe is communicated with the three-way pipe, and a pipe orifice in the axial direction of the three-way pipe is communicated with the connecting pipe.

The connection pipe needs to be installed below the secondary drainage hole, in order to provide the installation location of the connection pipe, the bottom of the support section 422 should have a gap, and in some cases, the secondary drainage hole may not be tightly connected to the connection pipe so as to permeate water, so that when the floor structure 1 is installed, the end of the waterproof layer 11 of the floor structure 1 in the horizontal direction is controlled to protrude from the end of the connection layer 12, that is, the coating area of the connection layer 12 is controlled to be smaller than the coating area of the waterproof layer 11, so that a half groove 101 is formed between the top of the waterproof layer 11 and the end of the connection layer 12; the support sections 422 are positioned within the half-channel 101 and the base section 421 and the connecting sections are connected to the top and end portions of the connecting layer 12, respectively. Based on this, a space for installing the connection pipe is formed between the support section 422 and the waterproof layer 11, and meanwhile, if the connection between the drainage hole and the connection pipe is not tight, water leaks, the water will fall onto the waterproof layer 11, so that the waterproof effect of the floor structure 1 is not affected.

Although the waterproof layer 11 plays a waterproof role, there is a possibility that the waterproof layer may be washed out and fall off after the waterproof layer is contacted with leaked water for a long period of time, and therefore, the secondary drainage member 4 further includes the protection plate 45, and the protection plate 45 includes the primary protection section 451 connected to the top of the waterproof layer 11 and the secondary protection section 452 connected to the end of the waterproof layer 11, so that damage to the waterproof layer 11 due to water leakage is avoided. Further, the end of the secondary protection section 452 extends towards the direction close to the support section 422 and forms a stop section 453, a secondary water accumulation groove 402 is formed among the stop section 453, the primary protection section 451 and the support closing plate 44, water leakage can be accumulated in the secondary water accumulation groove 402, and direct water is prevented from directly flowing below the floor structure 1 to influence the waterproof effect. And the accumulated water in the secondary accumulated water groove 402 can be sucked out through the secondary drain hole after the wallboard and the connecting pipe are disassembled. Because secondary ponding recess 402 is only used for gathering the infiltration condition between secondary wash port and the connecting pipe that probably exists and supplementary setting, consequently in the in-service use, need not to clear up frequently secondary ponding recess 402, when finding that there is the infiltration problem between secondary wash port and the connecting pipe, the time clear up in the time of changing the connecting pipe can, can not bring great operating pressure to the user.

According to the direction in fig. 3, the left half part of the secondary drainage member 4 with the structure is in suspended arrangement, the right half part is connected, and the suspended part can accumulate water to increase the stress, so that the secondary drainage member 4 has the problems of unbalance and easy tipping. In this embodiment, the secondary drainage member 4 first further includes a support closing plate 44 connected to the connection section and disposed in the half tank 101, and the primary protection section 451 is connected to the support closing plate 44. The support closing plate 44 is connected to the end of the connection layer 12 and/or the top of the waterproof layer 11. When the supporting and closing plate 44 is only connected with the top of the waterproof layer 11, the secondary drainage member 4 can tilt to drive the bottom end of the supporting and closing plate 44 to rotate towards the direction of the connecting layer 12, and the connection between the supporting and closing plate 44 and the waterproof layer 11 stops the trend, so that a certain supporting effect is achieved; at the same time, the support closing plate 44 itself also just blocks the secondary drain holes and the ends of the tie layer 12, functioning to close the tie layer 12. This is obviously also achieved when the support closing plate 44 is only connected to the end of the connecting layer 12, in which case the total length of the support closing plate 44 and the connecting section is preferably controlled to correspond to the thickness of the connecting layer 12. In this embodiment, both modes are set at the same time.

The secondary drainage member 4 further comprises a reinforcing plate arranged at the end part of the supporting and closing plate 44, the reinforcing plate is inserted into the bottom of the connecting layer 12 and positioned between the connecting layer 12 and the waterproof layer 11, and at the moment, the base layer section 421, the connecting section, the supporting and closing plate 44 and the reinforcing plate form a horizontal U-shaped structure, and the end part of the connecting layer 12 is coated and hooped, so that the stability of the secondary drainage member 4 is enhanced; and at the same time, water on the waterproof layer 11 is prevented from directly penetrating between the connection layer 12 and the waterproof layer 11 along the bottom end of the support closing plate 44.

Finally, the second baffle 43 is also adjusted, and the second baffle 43 includes an insertion section 431 inserted into the connection layer 12, and an abutment section 432 located outside the connection layer 12 for forming the wall of the wallboard mounting slot. At this time, the insertion section 431, the base section 421, the connection section, and the supporting and sealing plate 44 form an inverted U-shaped structure, which wraps around a portion of the top of the hooping connection layer 12, so as to enhance the stability of the secondary drainage member 4. Considering that the side of the insertion section 431 close to the floor structure 1 is connected to the connection layer 12, and that the connection layer 12 is usually made of cement, it has a certain contractibility, and water on the floor structure 1 may penetrate between the second baffle 43 and the connection layer 12, so that the installation mode of the floor structure 1 is further adjusted: the top of the connecting layer 12 is provided with a mounting groove, and the depth of the mounting groove is smaller than the thickness of the floor tile layer 13, so that after the floor tile layer 13 is mounted in the mounting groove, the floor tile layer comprises a lower mounting part arranged in the mounting groove and an upper surface part positioned outside the mounting groove. At this time, the insertion section 431 is disposed between the installation groove wall and the lower installation part; the abutting section 432 abuts against the upper surface layer portion, that is, most of the surface of the second baffle 43, which is close to the floor structure 1, abuts against the floor layer 13, and the shrinkage of the tile of the floor layer 13 is relatively small, so that a water seepage gap is not easily formed, and the waterproof effect is improved.

Further, in order to enhance the connection strength between the secondary drainage member 4 and the connection layer 12, friction lines are provided on the base layer section 421, the connection section, and the support closing plate 44, respectively.

The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
