As shown in fig. 1 and 2, the waterproof chassis is disposed on a floor structure 1 of a toilet or other space with drainage requirements, and the waterproof chassis is used for guiding water on the floor structure 1 into a sewer structure 2 of a building, and the sewer structure 2 is generally referred to as a sewer pipeline.

In the application, as shown in fig. 1, a floor structure 1 is erected above an original ground through a mounting frame, the mounting frame comprises a bearing plate which is basically consistent with the area of the original ground, the bearing plate is connected with the original ground through a plurality of support columns, the height of each support column can be independently adjusted, and the bearing plate can be adjusted to be horizontal by adjusting the heights of different support columns, so that the flatness of the subsequent floor structure 1 is ensured. 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.

In the prior art, through holes are usually directly formed in the floor structure 1 to drain water, and in the present application, in order to facilitate the installation of the wall panels and to facilitate the collection and drainage of the permeated water of the wall panels, a waterproof chassis is provided, which is mainly disposed at the end of the floor structure 1.

As shown in fig. 2, the waterproof chassis first includes a first barrier 41, a bottom plate 42, and a second barrier 43 connected in sequence, and a wall plate installation groove is formed between the first barrier 41, the bottom plate 42, and the second barrier 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 the drainage of the water in the primary water accumulation groove 401, a drain hole is provided in the support section 422, which communicates with the drain structure 2 through a connection pipe. The connecting pipe is preferably connected with the drain hole through a three-way pipe, and the three-way pipe comprises a horizontal pipe and a vertical water guide pipe, so that the water guide pipe is detachably connected with the drain hole for facilitating later maintenance. In this embodiment, after one end of the water conduit passes through the drain hole, a lap joint is disposed on the outer wall so as to lap joint on the support section 422, and the other end of the water conduit is communicated with the horizontal pipe through a sealing joint, and a pipe orifice in the axial direction of the horizontal pipe is communicated with the connecting pipe.

The connection pipe needs to be installed below the 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 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, after long-term contact with leaked water, the problem of scouring and falling may also exist, so the waterproof chassis further comprises a protection board 45, and the protection board 45 comprises a primary protection section 451 connected with the top of the waterproof layer 11 and a secondary protection section 452 connected with the end of the waterproof layer 11, so that damage to the waterproof layer 11 caused by 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 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 wash port and the connecting pipe that probably exists and supplementary setting, consequently in the in-service use, need not to clear up frequently to secondary ponding recess 402, when finding that there is the infiltration problem between wash port and the connecting pipe, the processing in the way clearance can when changing the connecting pipe, can not bring great operation degree of difficulty to the user.

According to the direction in fig. 2, the left half part of the structure is in a suspended arrangement, the right half part is connected, and the suspended part can accumulate water to increase the stress, so that the problems of unbalance and easy tipping exist. Based on this, in the present embodiment, the waterproof chassis first further includes a supporting closing plate 44 connected to the connection section and disposed in the half groove 101, and the primary protection section 451 is connected to the supporting 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 waterproof chassis can turn over 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 drain hole and the end of the connection layer 12, and functions to close the connection 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 waterproof chassis comprises a base layer section 421, a connecting section, a supporting closing plate 44 and a reinforcing plate, wherein the base layer section 421, the connecting section, the supporting closing plate 44 and the reinforcing plate form a horizontal U-shaped structure, the end of the connecting layer 12 is coated and hooped, and the stability of the waterproof chassis 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, an inverted U-shaped structure is also formed among the insertion section 431, the base section 421, the connection section 423 and the supporting and sealing plate 44, and the part of the top of the hooping connection layer 12 is covered, so as to enhance the stability of the waterproof chassis. 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.

In addition, friction lines are provided on the base layer section 421, the connection section, and the support closing plate 44, respectively, in order to enhance the connection strength between the waterproof chassis and the connection layer 12.

In the application, the waterproof chassis arranged at the wallboard mainly plays a role in assisting the collection and discharge of water at the wallboard, and the floor structure 1 is also required to be provided with a traditional drainage structure to slow down the drainage pressure of the waterproof chassis. Thus, in this embodiment, as shown in fig. 1, the floor structure 1 includes a main drain hole penetrating the floor structure 1 and the receiving plate, and water on the floor structure 1 flows through the main drain hole to the installation gap and into the drain structure 2. In consideration of the problems of erosion of water to the side wall of the main drain hole and steering of water flow in the flowing process, the main drain hole cannot be directly used, a sleeve is usually arranged in the main drain hole, the axial direction of the sleeve is parallel to that of the main drain hole, the sleeve is inserted into the main drain hole, the outer wall of the sleeve is connected with the inner wall of the main drain hole, and an actual drain channel is formed in the sleeve, so that the sleeve 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 is usually tightly connected with the connecting layer material at the inner wall of the main drain hole, but in order to improve the installation strength of the sleeve and avoid the falling of the sleeve 31, in this embodiment, a convex mounting ring is arranged on the outer wall of the upper end of the sleeve, 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 ground brick layers 13 and the sleeves and water seeps, if no mounting ring is arranged, the water can directly seep downwards between the connecting layer 12 and the sleeves, so that the connecting layer 12 is corroded; 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 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 into the through hole, and enabling the mounting ring of the sleeve to be inserted 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 end opening of the sleeve 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 so that accumulated water can smoothly flow in, and a cover plate is arranged at the upper end opening and is provided with a plurality of drain holes for draining water and preventing impurities with larger volume from entering the sleeve to cause blockage. The cover plate is preferably detachably connected to the sleeve to facilitate cleaning of the cover plate and the interior of the sleeve. For example, a boss can be arranged on the inner wall of the sleeve, and the cover plate is lapped on the boss.

The axial length of the sleeve is preferably greater than the length of the main drain hole such that the lower end opening of the sleeve extends into the installation gap and communicates with the drain structure 2, with the water supply flowing to the drain structure 2. Considering that the drainage direction of the sleeve is vertical and the drainage direction of the sewer structure 2 is horizontal, a steering conduit is further arranged between the lower end opening of the sleeve and the sewer structure 2, the steering conduit adopts 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, 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 chassis is waterproof, the drainage of the drainage structure 2 is influenced, and the water of the drainage structure 2 may flow reversely in the direction of the steering catheter, so that a backflow prevention drain core 34 is further arranged in the steering catheter, the backflow prevention drain core comprises 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, and is preferably detachably connected, such as in a threaded connection, so as to be convenient to replace, and the narrow-mouth end is suspended in the steering catheter. The wide-mouth end is a water inlet end, the narrow-mouth end is a water outlet end, and when the backflow problem exists in the drainage structure 2, the narrow-mouth end can stop the water flowing into the backflow-preventing leakage core 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 water flow mainly collides with the outer wall of the anti-reflux leakage core during reflux, and is not easy to enter the outlet of the narrow mouth end.

Further, a water seal cylinder is arranged in the steering guide pipe, the upper end of the water seal cylinder is opened, the caliber is preferably larger than the inner diameter of the sleeve, the lower end of the water seal cylinder is closed, meanwhile, the narrow opening end is inserted into the water seal cylinder, and an overflow port is formed between the top end of the water seal cylinder and the inner top of the steering guide pipe. When the anti-reflux water seal device is used, water flowing out of the anti-reflux water seal core and water possibly leaking out of the sleeve and the anti-reflux water seal core due to loose connection can flow into the water seal cylinder, and can flow out of the overflow port and then flow into the drainage structure 2 after the water seal cylinder is filled. Therefore, the water seal cylinder is always filled with water, and the narrow opening end is immersed in water, so that a water seal for opening the narrow opening end is formed, the gas escaping from the sewer structure 2 is further prevented from being deodorized through the main drain hole, and meanwhile, the cylinder wall of the water seal cylinder further stops the water in the sewer structure 2 from flowing back towards the narrow opening end, so that the cylinder height of the water seal cylinder is preferably improved, and the cylinder height is larger than the caliber of the pipe orifice of the sewer structure 2.
