Example 2

The embodiment of the application discloses a toilet waterproof structure and a construction method.

Referring to fig. 11, the present embodiment is different from embodiment 1 in the structure of the filter layer 41 and the construction method of the filter layer 41.

Referring to FIG. 11, the filter layer 41 includes a lower pad 414 and an upper pad 415 that mate with each other. The lower mat 414 is laid on the second waterproof layer 2 on the bottom plate 72.

Referring to fig. 12, the lower pad 414 is provided with a support post 4141, and the joint between the lower pad 414 and the support post 4141 is provided with an inclined guide surface 4142; the radial cross section of the post 4141 is a regular hexagon. The post 4141 is coaxially disposed with the lower pad 414.

Referring to fig. 13, the lower cushion block 414 may have a cylindrical structure with a regular hexagonal radial interface; the adjacent side of the lower pad 414 has a notch 4143. When the lower spacer 414 is laid on the second waterproof layer 2 on the bottom plate 72, the notch 4143 of the adjacent lower spacer 414 forms a water diversion hole penetrating the lower spacer 414, and cooperates with the inclined guide surface 4142 of the lower spacer 414 to form a diversion structure, thereby improving the drainage efficiency.

When the upper cushion block 415 is laid, the sleeve holes 4151 of the upper cushion block 415 are directly sleeved on the support columns 4141, additional positioning is not needed, the support columns 4141 on different lower cushion blocks 414 can be kept at intervals better, and the stability of the filter layer 41 is improved.

Referring to fig. 12, the inclined guide surface 4142 between the lower pad 414 and the post 4141 allows for clearance for drainage after the lower pad 414 is matingly installed with the upper pad 415. The upper cushion 415 is matched and clamped on the pillar 4141 of the lower cushion 414, so that a spatial structure capable of draining water can be formed by filtering, and the upper cushion 415 can limit the adjacent lower cushions 414 to turn over after being subjected to top pressure, so that the lower cushion 414 and the upper cushion 415 are stably installed.

The axial height of the sleeve hole 4151 is not less than the axial height of the support post 4141, so that the upper end surface of the support post 4141 is prevented from being exposed on the upper surface of the upper cushion block 415, and the flatness of the upper surface of the filter layer 41 is prevented from being influenced.

In use, the axial height difference of the post 4141 relative to the sleeve hole 4151 may be selected based on the actual situation. The axial height of the post 4141 is selected to be the same as the axial height of the pocket 4151 to maintain a flat upper surface of the filter layer 41 during placement of the upper pad 415. The axial height of the support posts 4141 is selected to be less than the axial height of the sleeve holes 4151 to provide a tight attachment of the filter layer 41 to the support layer 42 for the next construction step. And also facilitates the laying and positioning of the glass fiber mesh cloth 422 between the support layer 42 and the filter layer 41.
