Description

Waterproof roof and roof waterproofing method

Technical Field

The invention relates to the field of house construction, in particular to a waterproof roof and a roof waterproofing method.

Background

Roof waterproofing is an important component of building engineering, and the roof waterproofing method is related to the quality of the whole building engineering. Roof waterproof has since ancient times, and ancient building adopts the structural waterproof, because of ancient building is sharp roof, the roof slope is big, generally lays and pastes clay tile or glazed tiles waterproof. Modern buildings are mostly designed into flat roofs in order to meet the functionality and other functions of the roofs, and some equipment can be installed; some are designed as a roof for people to live on; some important buildings, sometimes designed as parking areas, are designed to park helicopters. The roof tile can not be used in flat roof engineering, so that the modern building changes structural water resistance into material water resistance, and invents various waterproof coiled materials, such as asphalt felt, aluminum foil felt, SBS coiled material, APF coiled material and polyethylene polypropylene fiber high polymer coiled material. The organic coiled material has good waterproofness and convenient construction, but the organic matters have a common weakness, and can be degraded under the change of ultraviolet rays and temperature along with the lapse of time, namely the organic matters are aged, and the waterproof system fails due to the aging of the coiled material and water leakage of a roof generally occurs in about ten years. Later, inorganic waterproofing was also used. The reinforced concrete rigid waterproof roof is a reinforced concrete cast-in-place roof, the compactness of concrete is increased in the construction process, and the reinforced concrete has a waterproof function by adding some waterproof agents. The rigid waterproof roof of reinforced concrete is cheap, and concrete is the inorganic matter, can not take place degradation ageing phenomenon. However, the construction requirement on concrete is high, large-area concrete can crack due to expansion with heat and contraction with cold under the temperature change, although steel bars cannot guarantee that the concrete does not crack for a long time, once the concrete cracks, a roof waterproof system fails, and a roof leaks water. In fact, the problem of roof waterproofing has been a difficult problem that plagues the construction industry for many years and has never been solved.

Accordingly, there is a need in the art for a more effective and durable roofing waterproofing solution.

Detailed Description

Embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention to those skilled in the art. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. Furthermore, it should be understood that the invention is not limited to the specific embodiments described. Rather, it is contemplated that the invention may be practiced with any combination of the following features and elements, whether or not they relate to different embodiments. Thus, the following aspects, features, embodiments and advantages are merely illustrative and should not be considered elements or limitations of the claims except where explicitly recited in a claim.

Referring now to fig. 1, a schematic structural view of a water resistant roof 100 according to an embodiment of the present invention is shown. As shown in fig. 1, the waterproof roof 100 includes:

a cement mortar buffer layer 110;

a metal tile layer 120 which is located on the cement mortar buffer layer 110 and comprises a plurality of metal tiles 121 which are tiled, wherein gaps are not formed among the plurality of metal tiles 121, and a plurality of drainage grooves 122 are formed;

a metal tile protection layer 130 located on the metal tile layer 120; and

a surface layer 140 which is located on the metal tile protection layer 130 and constitutes a surface of the waterproof roof 100.

In some embodiments, the waterproof roof 100 further comprises:

insulation (not shown); and

a protective layer of cement mortar (not shown) located above the insulation layer and below the buffer layer of cement mortar 110.

The cement mortar buffer layer 110 is used for buffering the contact surface between the upper metal tile 121 and the lower cement mortar protective layer, so as to prevent the metal tile 121 from being crushed, and plays a role in stabilizing. The cement mortar buffer layer 110 may be formed by starting to apply a cement mortar layer after the cement mortar protective layer is set. It is possible to start the laying of the metal tiles 121 thereon to form the metal tile layer 120 and to fix the metal tiles 121 in the cement mortar buffer layer 110, while the cement mortar buffer layer 110 is not yet solidified.

In some embodiments, the cement mortar buffer layer 110 may be integrated with the cement mortar protective layer. In still other embodiments, the waterproof roof 100 may be devoid of the insulation layer.

In some embodiments, the metal tile 121 may be made of a titanium-magnesium-aluminum alloy. In other embodiments, the metal tile 121 may be made of other aluminum alloys, other metal alloys, or other metals.

In some embodiments, the metal tile 121 may have a trapezoidal or rectangular cross section. In other embodiments, the metal tile 121 may have a semicircular or other cross-section. At the gutter or at the edge, corner, etc. of the house, the metal tile 121 can be designed with a corresponding profile.

In some embodiments, the metal tile layer 120 may be formed by overlapping a plurality of metal tiles 121. For example, as shown in fig. 1, each metal tile 121 may be stamped from thin sheet metal to form a trapezoid with an upward opening, and the upper base of the trapezoid extending to both sides. Thus, the upper bottom extensions of two adjacent metal tiles 121 are overlapped with each other without a gap for water leakage, and a drainage groove 122 is formed at the trapezoidal bottom of each metal tile 121. In other embodiments, there are other ways of overlapping adjacent metal tiles 121. In still other embodiments, the plurality of metal tiles 121 may also be integrally formed.

The opening of the drainage channel 122 should be directed to the outside of the house or gutter so that rainwater can flow to the outside of the house or gutter through the drainage channel 122 when it falls into the drainage channel 122 through the metal tile protective layer 130 and the surface layer 140. In some embodiments, the metal tiles 120 may be laid horizontally. In other embodiments, the metal tiles 120 may be laid with a slight inclination towards the outside of the house or gutter, i.e. the metal tiles 121 and the gutter 122 are both laid down along a slope in the water direction, so as to better facilitate the flow of rain water through the gutter 122 to the outside of the house or gutter. This can be achieved by slightly inclining the surface of the cement mortar breaker 110 toward the outside of the house or gutter.

The metal tile protection layer 130 is used for protecting the metal tiles 121, dispersing the pressure of cement tiles, reinforced concrete, objects placed on a roof and the like above, and preventing the metal tiles 121 from being damaged by pressure. In some embodiments, the metal tile protective layer 130 may include a corrosion-resistant wood board or a carbonized wood board. In other embodiments, the metal tile protective layer 130 may comprise other sheet materials. In the case where the surface layer 140 is formed of cast-in-place concrete, the corrosion-resistant wood board or the carbonized wood board may also function as a bottom form.

In some embodiments, the metal tile protection layer 130 is provided with a plurality of drainage holes (not shown) aligned with the drainage grooves 122, so that rainwater can flow into the drainage grooves 122 through the drainage holes and then drain, or further flow into the gutter and drain.

The surface layer 140 has no waterproof function, only protection, beauty and bearing functions, and provides a plane for convenient use. In some embodiments, the surface layer 140 may comprise cement tiles or reinforced concrete. If the surface layer 140 includes cement tiles, rainwater may flow into the drainage grooves 122 along the holes of the cement tiles and the drainage holes of the metal tile protective layer 130. If the surface layer 140 includes cast-in-place reinforced concrete, holes aligned with the drainage holes of the metal tile protective layer 130 may be reserved during casting so as to allow rainwater to smoothly flow into the drainage channels 122.

The waterproof roof 100 according to the embodiment of the present invention is described above with reference to the accompanying drawings, and it should be noted that the above description is only an example and not a limitation of the present invention. In other embodiments of the invention, the waterproof roof may include more, fewer, or different layers or components, and the positional, containment, functional, etc. relationships between the various layers or components may be different than those described and illustrated.

In another aspect of the invention, a method of waterproofing a roof is also provided. Referring now to fig. 2, a schematic flow diagram of a method of waterproofing a roof according to an embodiment of the present invention is shown. As shown in fig. 2, a method for waterproofing a roof according to an embodiment of the present invention includes the steps of:

in step 201, a layer of cement mortar is applied to the roof surface;

in step 202, paving a plurality of metal tiles on the cement mortar, wherein gaps do not exist among the metal tiles, and a plurality of drainage grooves are formed;

in step 203, paving an anti-corrosion wood board or a carbonized wood board on the metal tile; and

in step 204, cement tiles or reinforced concrete are stuck on the anti-corrosion wood boards or the carbonized wood boards.
