Abstract

The utility model discloses a basement roof structure, including top layer, geotechnological cloth filter layer, plastics drain bar, concrete protective layer, non-woven polyester fiber cloth isolation layer, SBS modified asphalt waterproofing membrane waterproof layer, pitch layer, cement mortar screed-coat, polyurethane waterproof coating layer and the waterproof concrete roof that from top to bottom sets gradually. This basement roof structure can improve water-proof effects.

Description

Underground chamber roof structure

The technical field is as follows:

the utility model relates to a building field specifically says a basement roof structure.

Background art:

the existing building is provided with a basement in order to fully utilize the space, the waterproof performance requirement of a top plate structure of the basement is very high, but the existing basement top plate structure is still to be further improved, and the waterproof performance is improved.

The utility model has the following contents:

the utility model aims to solve the technical problem that a basement roof structure that can improve water-proof effects is provided.

The technical solution of the utility model is that, a basement roof structure is provided, including top layer, geotechnological cloth filter layer, plastics drain bar, concrete protective layer, non-woven polyester fiber cloth isolation layer, SBS modified asphalt waterproofing membrane waterproof layer, pitch layer, cement mortar screed-coat, polyurethane waterproofing coating layer and the waterproof concrete roof that from top to bottom sets gradually.

Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: the structure has good waterproof effect.

Preferably, the surface layer is a covering soil, greening and pavement layer.

Preferably, the concrete protective layer is filled with steel bars.

Furthermore, the plastic drainage plate comprises a bottom plate and circular truncated cone-shaped salient points which are arranged on the bottom plate in an integrated mode, drain holes penetrate through the salient points, and a plurality of criss-cross water storage tanks are concavely arranged on the bottom plate between the salient points. Can accumulate a small amount of water, is more beneficial to the growth of surface vegetation compared with a plastic drainage plate with sealed salient points,

description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic structural view of the plastic drain board.

The specific implementation mode is as follows:

the invention will be further explained with reference to the drawings and the detailed description below:

as shown in fig. 1-2, a structure of a roof of a basement comprises a surface layer 1, a geotextile filter layer 2, a plastic drainage plate 3, a concrete protective layer 4, a non-woven polyester fiber cloth isolation layer 5, a SBS modified asphalt waterproof coiled material waterproof layer 6, an asphalt layer 7, a cement mortar leveling layer 8, a polyurethane waterproof coating layer 9 and a waterproof concrete roof 10 which are arranged from top to bottom in sequence, wherein, the concrete protective layer 4 is filled with steel bars with the thickness of 70mm, the surface layer 1 is a covering soil layer, a greening layer and a pavement layer, in order to better promote the growth of greening vegetation, the plastic drainage plate 3 comprises a bottom plate 31 and truncated cone-shaped convex points 32 which are integrally arranged on the bottom plate, drain holes 33 penetrate through the convex points 32, the drain holes 33 are positioned at the upper ends of the convex points, the convex points 32 are arranged upwards, and a plurality of criss-cross water storage tanks 34 are concavely arranged on the bottom plate between the convex points. The water storage tank can play a role in storing a small amount of water, growth of plants on the surface layer is facilitated, and the water drainage holes can drain water to avoid cracking caused by uneven water on the surface layer. The cement mortar leveling layer is used as a damp-proof layer, the protective layer and the isolation layer can protect the waterproof layer, the asphalt layer can protect the polyurethane waterproof coating layer, and the SBS modified asphalt waterproof coiled material waterproof layer can be directly laid on the asphalt layer in a dry mode.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
