DETAILED DESCRIPTION

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] The terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, commodity, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, commodity, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not preclude the presence of additional identical elements in the process, method, commodity, or apparatus that includes the element.

[0046] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and do not specifically indicate an order or sequence, nor are they intended to limit the disclosure. These terms are merely used to distinguish components or operations described with the same technical terminology, and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features being referred to. Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one such feature.

[0047] The present invention uses a drop-slab roof, a standing seam metal roof and a permeable sheet material to form an organized drainage system for irregularly pitched roofs. The irregularly pitched roofs include two or more mono-pitched roofs, each with a different slope and direction, but with the same structure. Figure 1 The scope of irregular slope roofs is defined, including irregular slope roof prototypes, flat slope combined with irregular slope roofs, centripetal irregular slope roofs, combined irregular slope roofs and other forms.

[0048] Reference Figures 2 to 7 The present application provides an irregular slope roof partition drainage system, comprising the following parts:

[0049] The standing seam metal roof and water-permeable panel 1 comprises a 0.7mm thick roof panel 101 and a 0.7mm thick perforated panel (r=5mm aperture) 104, which are supported by a metal support 102 and connected by no less than 4 bolts 103 with a size of 4M20. One side of the perforated panel 104 is overlapped with the surface layer of the roof panel, and the other side is connected to the concrete roof embedded corner piece by bolts. The roof panel 101 and the perforated panel 104 respectively play the roles of preliminary rainwater drainage and filtering of larger particle size impurities.

[0050] The standing seam metal roof and water-permeable panel, after receiving rainwater from the roof panel 101 covering the roof and draining the rainwater, filters the rainwater through the perforated panel 104 to the directly below drainage gutter.

[0051] In some embodiments of the present application, the perforated panel 104 is an aluminum panel, and the roof panel 101 is a titanium-zinc roof panel. The galvanized roof panel has the ability of corrosion resistance and weather resistance, and has a very low replacement frequency. Replacing the original slope drainage method relying on the main structure of the roof can further reduce the cost of post-maintenance of slope roof buildings.

[0052] The dropped slab roof 2 is made of reinforced concrete. The upper part of the dropped slab area is paved with a leveling layer 202, a waterproof layer, and a protective layer 205. In one embodiment of the present application, two waterproof layers are paved, including a first waterproof layer 203 and a second waterproof layer 204.

[0053] In some embodiments of the present application, the keel is a light steel keel frame 301 with a cross-sectional size of 100mm*100mm and a tube wall thickness of 5mm, which is welded by galvanized square steel with a spacing of 1200*1200. The end of the keel frame 301 is welded and connected to the slope roof main structure counter-knock embedded part 303 by galvanized square steel (with the same material as the light steel keel frame 301). The upper part of the light steel keel frame 301 supports the 30*30 galvanized square steel purlin 302, and the keel frame 301 is used to support the 0.7mm thick roof panel 101 on the upper part.

[0054] The drainage gutter 4 is integrally poured with reinforced concrete together with the slope roof and the dropped slab roof. The surface of the drainage gutter 4 is sequentially paved with a waterproof layer and a protective layer.

[0055] The communication groove 5 connects the high area drainage area 6 and the low area drainage area 7, and the main structure is integrally poured with the dropped slab roof 2.

[0056] High zone drainage area 6, in coplanar relationship with the falling plate area and separated by the roof ridge, is located at the lowest height of the drainage gutter 4, which is the collection area for the rainwater drainage of the drainage gutter 4. The surface is sequentially laid with a waterproof layer and a protective layer.

[0057] Low zone drainage area 7, in coplanar relationship with the drainage gutter 4, and separated by the ridge where the connecting channel 5 is located, is located at the lowest height of each single-roof drainage subarea. The surface is sequentially laid with a waterproof layer and a protective layer.

[0058] The downpipe system includes a downspout 8 and a downpipe 9, and each of the high zone drainage area 6 and the low zone drainage area 7 is connected to a downspout 8. Each downspout is connected to a downpipe 9 to drain rainwater into the municipal rainwater pipeline. The downspout 8 and the downpipe 9 are connected by a double-pipe sleeve, the downpipe 9 is clamped by a pipe fixing member, and the pipe fixing member is nailed to the building wall surface by expansion bolts. In some embodiments of the present application, the downpipe 9 is a PVC pipe.

[0059] Working principle: The reinforced concrete sloping roof partition drainage roof structure system forms a structural main body through the integrated pouring of the falling plate structure roof gutter drainage channel. The upper part uses the gable frame 3 to support the standing seam metal roof and the water permeable board 1, which greatly enhances the ability of this type of sloping roof to have organized planning drainage area, temporary water storage, and efficient drainage. Under the action of gravity formed by the same slope of the covered roof and the standing seam metal roof and the water permeable board 1, the roof panel 101 uses the slope to preliminarily drain the direction of roof rainwater, and the perforated plate 104 intercepts and filters large-particle debris through the perforations. The anti-interference ability and the efficient drainage efficiency of the organized drainage of the sloping roof are strengthened, and the difficulty and labor cost of later maintenance and cleaning of the sloping roof are reduced. The drainage gutter 4 receives filtered rainwater, and its own slope causes the rainwater to flow to the high zone drainage area 6 and a small part to the low zone drainage area 7. At this time, the high zone drainage area 6 mainly undertakes roof drainage, and the low zone drainage area 7 assists in undertaking roof drainage. In areas with abundant rainfall, the roof drainage capacity is strengthened. At the same time, the high zone drainage area 6 and the low zone drainage area 7 are connected by the connecting channel 5 at the high water level, which can avoid the phenomenon of unorganized drainage caused by the high zone drainage area 6 due to rainfall exceeding its temporary water storage capacity. At this time, the high and low drainage areas jointly undertake the task of roof drainage.

[0060] Finally, it should be noted that the examples described are merely illustrative of the technical solutions of the present application, and are not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that equivalent replacements or size changes can be made to some devices or elements described in the foregoing examples, and such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
