DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] The present application embodiment discloses a waterproof room floor structure, such as Figure 1 As shown, from bottom to top, it includes a foundation leveling layer 1, an intermediate layer 2, a first waterproof layer 6, a protective leveling layer 7 and a surface layer 9, and below the leveling layer is a floor slab 8. The intermediate layer 2 includes an extruded board 21 and a plurality of boundary concrete strips 23, the boundary concrete strips 23 are long strips of prefabricated lightweight aggregate concrete blocks, and the extruded board 21 is an extruded polystyrene board; a single boundary concrete strip 23 is located at one edge of the intermediate layer 2 and is detachably connected to the foundation leveling layer 1, and an elastic sealing body 22 is fixedly connected between the boundary concrete strip 23 and the extruded board 21. This structure can be used for both prefabricated buildings and cast-in-place structural buildings, so the floor slab 8 can be a cast-in-place floor slab or a prefabricated prefabricated floor slab.

[0028] like Figure 1As shown, the foundation leveling layer 1 is a cast-in-place cement structure, on which a pre-buried connection tube 11 is fixedly connected, the tube mouth of the pre-buried connection tube 11 faces upward, and a connection bolt 236 is penetrated in the vertical direction on the boundary concrete strip 23, and the connection bolt 236 is screwed into the pre-buried connection tube 11 and the two are coaxially threaded. The hole on the boundary concrete strip 23 for the connection bolt 236 to pass through is a connection hole 231, and the hole diameter of the connection hole 231 is larger than the diameter of the connection bolt 236. A countersunk groove 232 is provided on the boundary concrete strip 23 and at the upper end of the hole 231. The screw head of the connection bolt 236 is located in the countersunk groove 232. A spring gasket is provided between the screw head of the connection bolt 236 and the boundary concrete strip 23, and the spring gasket is not squeezed to a flat state after the connection bolt 236 is screwed in. A stainless steel hard round rod 3 is provided between the boundary concrete strip 23 and the foundation leveling layer 1. The length direction of the hard round rod 3 is consistent with the length direction of the boundary concrete strip 23. The hard round rod 3 is located between the connecting bolt 236 and the elastic sealing body 22. A docking groove 12 is provided on both the boundary concrete strip 23 and the foundation leveling layer 1. The cross section of the docking groove 12 is semicircular and the notches of the two docking grooves 12 are opposite. The bottom of the docking groove 12 is coated with a waterproof coating. The two docking grooves 12 are interlocked, the hard round rod 3 is located therein, and the side wall of the hard round rod 3 abuts against the bottom of the docking groove 12.

[0029] like Figure 1 As shown, a boundary waterproof layer 4 is provided on the side of the boundary concrete strip 23 away from the extruded board 21, and the boundary waterproof layer 4 abuts against the side wall of the boundary concrete strip 23. A sealing wing edge 41 is integrally formed on the side of the boundary waterproof layer 4 facing the boundary concrete strip 23. The boundary concrete strip 23 and the foundation leveling layer 1 abut against the opposite sides of the sealing wing edge 41, respectively. The sealing wing edge 41 only exists on the side of the connecting bolt 236 away from the hard round rod 3. The boundary waterproof layer 4 needs to be installed in place at the same time as the boundary concrete strip 23 and the foundation leveling layer 1 are installed with each other, and the side of the boundary waterproof layer 4 away from the boundary concrete strip 23 is in contact with the surface of the wall 5. A second waterproof layer 13 is also laid between the extruded board 21 and the foundation leveling layer 1.

[0030] It should be pointed out that in this embodiment, the first waterproof layer 6 and the second waterproof layer 13 can be formed by coating one or more of waterproof paint, waterproof coating, waterproof glue, etc., or waterproof membrane can be used. The boundary waterproof layer 4 with a sealing wing edge 41 is preferably a waterproof membrane with an L-shaped cross-section.

[0031] like Figure 1As shown, an extended slope 234 is integrally formed above the boundary concrete strip 23, and the slope of the extended slope 234 faces the side away from the boundary waterproof layer 4, that is, the outer upper edge of the boundary concrete strip 23 is higher than the inner upper edge, the upper surface of the extruded board 21 and the inner upper edge of the boundary concrete strip 23 are at the same height, and the first waterproof layer 6 and the protective leveling layer 7 are both located within the height range of the extended slope 234. An auxiliary sealing rib 42 is integrally formed on the side of the boundary waterproof layer 4 facing the boundary concrete strip 23, and a butt rib 235 is pre-embedded and fixedly connected to the top of the extended slope 234. The length directions of the auxiliary sealing rib 42 and the butt rib 235 are the same as the length direction of the boundary concrete strip 23, and the cross-sections of the auxiliary sealing rib 42 and the butt rib 235 are both circular, and the material of the butt rib 235 is polyvinyl chloride, and the butt rib 235 and the lower side of the auxiliary sealing rib 42 are in contact with each other.

[0032] like Figure 1 As shown, the surface layer is the uppermost layer of the ground structure. In this embodiment, the surface layer 9 is formed by paving tiles; the upper surface of the surface layer 9 is flush with the upper edge of the auxiliary sealing rib 42.

[0033] The present application also discloses a construction method for the above-mentioned waterproof room floor structure, such as Figure 1 and 2 As shown, the following steps are included in sequence: S1: pouring concrete on the upper surface of the floor slab 8, curing and forming a first leveling layer, embedding the embedded connecting tube 11 and forming the docking groove 12 during the solidification process of the concrete; S2: spraying base treatment agent on the upper surface of the first leveling layer; S3: Forming of the middle layer 2: constructing the second waterproof layer 13, the boundary waterproof layer 4, the extruded board 21, the hard round rod 3, and installing the boundary concrete strip 23; S4: Filling the space between the extruded board 21 and the boundary concrete strip 23 with the tissue material of the elastic sealing body 22 to form it, the tissue material of the elastic sealing body 22 includes aggregate, hemp and asphalt, and now the aggregate and hemp are filled into the space between the extruded board 21 and the boundary concrete strip 23, and then pouring asphalt therein and waiting for it to solidify and fix; S5: Fill the countersunk groove 232 with foaming material, and scrape the upper surface of the boundary concrete strip 23 or the extended slope edge 234 flat; S6: The first waterproof layer 6 and the protective leveling layer 7 are constructed in sequence, and an interface agent is coated on the side of the first waterproof layer 6 facing the protective leveling layer 7 .

[0034] S7: Lay ceramic tiles on the protective leveling layer 7 to form a surface layer 9, and seal the gap between the ceramic tiles at the edge of the surface layer 9 and the wall 5 with a sealant.

[0035] The implementation principle of a waterproof room floor structure and construction method in the embodiment of the present application is as follows: Since the extruded board 21 and the boundary concrete strip 23 are not in direct contact, and the elastic sealing body 22 also has a certain elastic deformation ability, the expansion and contraction of the extruded board 21 has almost no effect on the boundary concrete strip 23. After the ground structure is formed, the boundary concrete strip 23 is almost surrounded by waterproof elastic materials (elastic sealing body 22, boundary waterproof layer 4, first waterproof layer 6). The connecting bolts 236 are used to ensure the stability of the boundary concrete strip 23 relative to the foundation leveling layer 1. At the same time, the elasticity of the spring gasket allows the boundary concrete strip 23 to have space conditions for slight activities. The hard round rod 3 is the only hard connection point of the boundary concrete strip 23 relative to the foundation leveling layer 1. When the boundary concrete strip 23 is subjected to a force perpendicular to its own length direction, the hard round rod 3 can be used as a fulcrum to convert the horizontal displacement trend of the boundary concrete strip 23 into a rotation trend, which can produce an extrusion force on most of the surrounding elastic materials, thereby weakening the overall separation trend between the boundary concrete strip 23 and the boundary waterproof layer 4 or the elastic sealing body 22.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
