Description

Technical Field

[0001] The invention relates to the field of roof waterproofing, and in particular to a puncture-resistant weldable nail cover, a roof system and an installation method thereof. Background Art

[0002] With the progress and development of science and technology, metal, as a widely used material in the construction industry, metal roofs have become the choice of many owners, and the waterproofness of the roof has a profound impact on metal roofs.

[0003] The current waterproofing measure is to use film-coated metal sheets for roof construction. The construction method is: the film-coated metal sheets are connected by overlapping, overlapping the overlapping edges, and connected into a whole with various bolts, rivets or self-tapping screws. However, this construction method exposes the roof screws to the outside, which easily causes the nail heads and the metal sheets in contact with the nail heads to oxidize and rust the roof in the natural environment, thus causing roof leakage and affecting indoor production and life; even later repairs cannot completely solve the leakage problem. Summary of the invention

[0004] In view of the deficiencies in the prior art, an object of the present invention is to provide a puncture-resistant weldable nail cover, a roofing system and an installation method thereof.

[0005] The first aspect of the present disclosure provides a puncture-resistant weldable nail cap, which is applied to a roofing system. The roofing system includes a fusion tile and a connector end protruding from the surface of the fusion tile, including:

[0006] The nail cover body has a receiving space for receiving the end of the connector and an opening for allowing the end of the connector to enter the receiving space, and the opening passes through the receiving space;

[0007] A skirt is connected to the nail cover body and is arranged around the opening. The skirt is used to be fixedly connected to the surface of the fusion tile to seal the end of the connecting piece between the nail cover body and the fusion tile.

[0008] Optionally, the supporting strength of the nail cover body is greater than the supporting strength of the skirt, and the thickness of the nail cover body is greater than the thickness of the skirt.

[0009] Optionally, the outer surface of the nail cover body is a curved surface.

[0010] Optionally, the skirt is connected to the outer surface of the nail cover body.

[0011] Optionally, the skirt is integrally formed with the outer surface of the nail cover body.

[0012] Optionally, the opening is circular or elliptical.

[0013] Optionally, the nail cover body is in the shape of a hollow hemisphere or a hollow cone.

[0014] Optionally, the thickness of the nail cover body decreases gradually from an end away from the opening to an end close to the opening.

[0015] A second aspect of the present disclosure provides a roofing system, comprising a fusion tile, a connector and the nail cover described in the first aspect; the fusion tile is laid on a roof purlin, and adjacent fusion tiles overlap each other; the connector connects the fusion tile to the roof purlin and the overlapping parts between adjacent fusion tiles, and the connector end of the connector protrudes from the surface of the fusion tile; the nail cover is arranged on the fusion tile, the nail cover body of the nail cover covers the connector end, and the skirt of the nail cover is welded to the surface of the fusion tile to seal the connector end between the nail cover body and the fusion tile.

[0016] The third aspect of the present disclosure provides a method for installing a roofing system, which is used to install the roofing system of the second aspect, comprising: laying fusion tiles on roof purlins, overlapping adjacent fusion tiles; connecting the fusion tiles with the roof purlins and the overlapping parts between adjacent fusion tiles using connectors; and covering the connector ends protruding from the surfaces of the fusion tiles using nail covers;

[0017] Among them, the use of a nail cover to cover the connector end protruding from the surface of the fusion tile on the connector includes: placing the nail cover on the surface of the fusion tile so that the nail cover body of the nail cover covers the connector end, and the skirt of the nail cover is welded to the surface of the fusion tile, thereby enclosing the connector end between the nail cover body and the fusion tile.

[0018] The implementation of the above scheme has the following beneficial effects:

[0019] The nail cover disclosed in the present invention includes a nail cover body and a skirt. The nail cover body has a strong supporting force and can cover the end of the connector protruding on the surface of the fusion tile. The skirt is fixedly connected to the fusion tile, thereby constructing a closed space between the nail cover and the fusion tile, enclosing the end of the connector in this space, avoiding the end of the connector from being exposed to the outside and causing rust, thereby preventing the metal plate of the fusion tile from being partially oxidized and rusted. At the same time, due to the arched space design of the nail cover body, the end of the connector contacts or maintains a gap with the nail cover body, reducing the friction damage of the end of the connector to the nail cover, and the arched nail cover has a strong supporting strength, further improving the puncture resistance of the nail cover.

[0035] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] The embodiment of the present disclosure provides a puncture-resistant weldable nail cover, which is applied to the roof system and can cover the parts of the roof system that are at risk of rust, so as to reduce or isolate the influence of external moisture on these parts. The roof system includes a fusion tile 100 and a connector end 201 protruding from the surface of the fusion tile 100. The fusion tile 100 is laid on the roof purlin 400, and adjacent fusion tiles 100 overlap each other; the connector 200 connects the fusion tile 100 with the roof purlin 400 and the overlapping parts between adjacent fusion tiles 100, and the connector end 201 of the connector 200 protrudes from the surface of the fusion tile 100. The fusion tile 100 is a TPO coated metal plate pressed into a tile shape, including a metal substrate and a TPO waterproof membrane covered on the metal substrate. The connector 200 can be a screw, a nut, a clamping part, etc., and its material contains iron, which is easily corroded when exposed to water vapor for a long time. The connector end 201 can be, for example, a nail head.

[0037] See also Figure 1-Figure 3The nail cover 300 may include a nail cover body 301 and a skirt 302. The nail cover body 301 has a receiving space 303 for receiving the connector end 201 and an opening 304 for the connector end 201 to enter the receiving space 303, and the opening 304 passes through the receiving space 303; the skirt 302 is connected to the nail cover body 301 and is arranged around the opening 304. The skirt 302 is used to be fixedly connected to the surface of the fusion tile 100 to enclose the connector end 201 between the nail cover body 301 and the fusion tile 100.

[0038] The material of the skirt 302 is the same as the surface material of the fusion tile 100, that is, the material of the skirt 302 and the surface of the fusion tile 100 are both TPO waterproof materials, and the two have good compatibility. The skirt 302 can be fixed to the surface of the fusion tile 100 by hot air welding.

[0039] The outer surface of the nail cover body 301 is a curved surface, which is conducive to the sliding of rainwater and avoids water accumulation in the nail cover body 301; at the same time, the curved surface can disperse stress and strengthen the supporting strength of the nail cover body 301. The skirt 302 is connected to the outer surface of the nail cover body 301. Specifically, the skirt 302 and the outer surface of the nail cover body 301 can be integrally formed, which improves the aesthetics of the outer surface of the nail cover 300 and is conducive to water diversion.

[0040] The opening 304 of the nail cover body 301 is larger than the cross-sectional width of the connector end 201, and the height of the accommodation space 303 of the nail cover body 301 is larger than the height of the connector end 201, so as to ensure that the nail cover 300 completely covers the connector end 201. The connector end 201 does not contact the skirt 302 of the nail cover 300, and a gap is provided between the connector end 201 and the inner wall of the nail cover body 301, so that the nail cover 300 does not directly contact the connector end 201, thereby preventing the connector end 201 from piercing the nail cover 300. In practical applications, the connector end 201 is allowed to be close to or just in contact with the inner wall of the nail cover body 301, so that the stress exerted by the connector end 201 on the nail cover body 301 is not enough to pierce the nail cover body 301.

[0041] The supporting strength of the nail cover body 301 is greater than the supporting strength of the skirt 302, and the thickness of the nail cover body 301 is greater than the thickness of the skirt 302. In a possible implementation, the thickness of the nail cover body 301 decreases from the end away from the opening 304 to the end close to the opening 304, which can ensure that the nail cover body 301 has sufficient supporting strength and make the transition between the nail cover body 301 and the skirt 302 smoother and more natural, avoiding the generation of sharp structures such as steps at the transition between the nail cover body 301 and the skirt 302.

[0042] In a possible implementation, the shape of the nail cover body 301 is a hollow hemisphere or a hollow cone. The opening 304 of the nail cover body 301 can be circular or elliptical.

[0043] In a possible implementation, the skirt 302 and the nail cover body 301 may be integrally formed by an in-mold injection molding process.

[0044] The nail cover 300 of this embodiment includes a nail cover body 301 and a skirt 302. The nail cover body 301 has a strong supporting force and can cover the connector end 201 protruding from the surface of the fusion tile 100. The skirt 302 is fixedly connected to the fusion tile 100, thereby constructing a closed space between the nail cover 300 and the fusion tile 100, enclosing the connector end 201 in this space, preventing the connector end 201 from being exposed to the outside and rusting, and further preventing the metal plate of the fusion tile 100 from being partially oxidized and rusted. At the same time, due to the arched space design of the nail cover body 301, the connector end 201 contacts or maintains a gap with the nail cover body 301, reducing the friction damage of the connector end 201 to the nail cover 300, and the arched nail cover 300 has a strong supporting strength, further improving the puncture resistance of the nail cover 300.

[0045] This embodiment also provides a roofing system, see Figure 4 The roof system includes a fusion tile 100, a connector 200 and a nail cover 300 of the above embodiment. The fusion tile 100 is laid on the roof purlin 400, and adjacent fusion tiles 100 overlap each other; the connector 200 connects the fusion tile 100 and the roof purlin 400 and the overlapping parts between adjacent fusion tiles 100, and the connector end 201 of the connector 200 protrudes from the surface of the fusion tile 100; the nail cover 300 is arranged on the fusion tile 100, the nail cover body 301 of the nail cover 300 covers the connector end 201, and the skirt 302 of the nail cover 300 is welded to the surface of the fusion tile 100, so that the connector end 201 is enclosed between the nail cover body 301 and the fusion tile 100.

[0046] The present embodiment also provides a method for installing a roofing system, which is used to install the roofing system of the above embodiment, and the installation method includes: laying the fusion tile 100 on the roof purlin 400, and overlapping adjacent fusion tiles 100; using the connector 200 to connect the fusion tile 100 with the roof purlin 400 and the overlapping parts between adjacent fusion tiles 100; using the nail cover 300 to cover the connector end 201 protruding from the surface of the fusion tile 100 on the connector 200. Among them, using the nail cover 300 to cover the connector end 201 protruding from the surface of the fusion tile 100 on the connector 200 includes: placing the nail cover 300 on the surface of the fusion tile 100, so that the nail cover body 301 of the nail cover 300 covers the connector end 201, and the skirt 302 of the nail cover 300 is welded to the surface of the fusion tile 100, so that the connector end 201 is enclosed between the nail cover body 301 and the fusion tile 100.

[0047] The beneficial effects of the nail cover of this embodiment are described below in conjunction with a comparative example.

[0048] Comparative Example 1: A homogeneous TPO sheet is used as the nail cover.

[0049] Homogeneous TPO sheets can be used as nail covers after cutting. They are made of the same material as TPO waterproof membranes and have good compatibility. Therefore, they are easy to be hot-air welded with TPO membranes or TPO metal-coated panels. However, because TPO sheets are soft, the nail heads exert continuous external stress on the TPO sheets. Over time, the nail covers are easily punctured by the nail heads and lose their function of isolating water vapor.

[0050] Comparative Example 2: TPO butyl rubber is used as the nail cover.

[0051] TPO butyl adhesive can be used by bonding, and its construction speed is faster than that of welded TPO homogeneous sheets or injection molded sheets. However, because it is a hot-melt pressure-sensitive adhesive, its peel strength is much lower than that of welded ones, and its peel strength decays greatly after heat aging. Its long-term weather resistance is not as good as that of welded ones.

[0052] In this embodiment, the nail cover 300 is composed of a nail cover body 301 with high puncture strength and a skirt 302 made of TPO sheet material, which is formed by in-mold injection molding. The skirt 302 of the nail cover 300 can be welded to the TPO waterproofing coil or TPO coated metal plate by hot air welding, and the nail head is sealed between the nail cover body 301 and the fusion tile 100, which has high weather resistance and prevents the nail head from being corroded and damaged.
