Description

Technical Field

[0001] The invention belongs to the field of architectural design, and in particular relates to an irregular slope roof partition drainage system. Background Art

[0002] As a design form, building pitched roofs are now adopted by a large number of public buildings. In the Lingnan and coastal areas of my country, building pitched roofs have natural drainage advantages in the face of high precipitation such as summer monsoons and typhoons in summer.

[0003] In the prior art, the drainage form of the sloped roof is to drain to the downpipe system by relying on its own slope. However, when the building design has multiple slopes and irregular roofs, there are the following problems: ① Due to the complex roof slope, there is unorganized runoff of rainwater, which makes drainage difficult; ② Large-scale rainwater accumulation is easily formed at the intersection of multiple slopes, and if the drainage is not timely, it will exceed the maximum water storage capacity of the roof drainage partition; ③ The roof drainage structure is difficult to integrate with the building design, and the construction is complicated. When there is extreme weather with heavy precipitation, especially when accompanied by strong winds and debris, there are the following problems: ① Roof drainage is difficult to drain a large amount of rainwater from the roof in a short period of time, and the temporary water storage capacity is weak; ② The downpipe has weak ability to resist debris, which further reduces the drainage efficiency; ③ Cleaning is difficult, the cleaning cycle is short, and the later maintenance cost is high. Summary of the invention

[0004] In order to solve at least one of the problems existing in the prior art, the present invention provides an irregular slope roof partition drainage system, wherein the structural roof adopts a main body drop plate and a drainage gutter to be integrally cast to form a relative height structure mode. The roof panel and the perforated plate are connected to the roof through a keel connection.

[0005] To achieve the purpose of the present invention, the present invention provides an irregular slope roof partition drainage system, including a standing seam metal roof, a permeable sheet material and a drop-down roof:

[0006] The upright lock-edge metal roof and the permeable plate are supported by a keel frame, and include a roof panel and a perforated plate, which respectively play the role of initially draining rainwater and filtering larger particle-size debris. The drop-down roof includes a drop-down area and a drainage gutter. The perforated plate covers the drainage gutter, and the roof panel is located above the drop-down area. There is a relative elevation difference between the drop-down area and the drainage gutter to form a high drainage area and a low drainage area at the bottom of the roof, and the high drainage area and the low drainage area are connected by a connecting groove.

[0007] The dropped roof and drainage gutters are used to form a zoned drainage system with different roof elevations. The upright lock-edge metal roof and permeable panels function to receive precipitation and organized runoff to the drainage gutters.

[0008] Furthermore, purlins are laid on the keel frame, and perforated plates and roof panels are laid on the purlins.

[0009] Furthermore, the roof panel is connected to the structural roof in the form of a keel. The roof panel and the bottom aluminum alloy keel are parallel to the roof surface layer, and the color and texture of the roof surface layer are changed according to design requirements.

[0010] The long side of the roof panel surface is parallel to the roof slope.

[0011] One side of the perforated plate is overlapped with the roof panel surface layer, and the other side is connected to the embedded corner piece of the concrete roof through bolts.

[0012] Furthermore, it also includes a downpipe system, which includes a downpipe hopper, and the high-zone drainage area and the low-zone drainage area are both correspondingly provided with downpipes.

[0013] Furthermore, the downpipe system also includes a downpipe, and the downpipe is connected to the municipal rainwater pipe through the downpipe.

[0014] Furthermore, the surface layers of the drop-down roof area and the drainage gutter are parallel and have the same slope, wherein the two surface layers have a relative height, and the relative height of the drop-down roof area is lower than that of the drainage gutter, and the two are separated by a roof anti-slope.

[0015] In the high drainage area of ​​the roof, a temporary water reservoir is formed by utilizing the relative height formed by the drop-down roof and the drainage gutter, and the surface layer of the water reservoir is coplanar with the drop-down roof. The low drainage area is coplanar with the drainage gutter.

[0016] There are two connecting grooves in the high and low drainage areas of the roof. The connecting grooves are used to flow to the low drainage area when the water storage tank in the above-mentioned high area reaches the water storage limit. Downspouts are provided in the high and low drainage areas. The downspouts in the two drainage areas respectively drain rainwater into the municipal rainwater pipes through their respective connected downpipes.

[0017] The low-zone drainage area and the drainage gutter are in a coplanar relationship, and the two are separated by a roof sill, and the sill has the above-mentioned two connecting grooves.

[0018] Preferably, the downpipe is a PVC downpipe.

[0019] Preferably, a downspout is set in each high and low drainage area, and its downspout elevation is 0.05m lower than the relative drainage area elevation. Use waterproof paint and grease to seal the joint. The rain gutter and PVC downspout are connected by a double-pass sleeve, and an inspection port is set at a position 0.9m above the floor elevation. The pipe fixings are sleeves to clamp the PVC downspout, and the spacing is not less than two for every 4m. The pipe fixings are nailed into the building wall with expansion bolts.

[0020] Furthermore, a waterproof layer and a protective layer are sequentially laid on the surface layer of the drainage gutter.

[0021] Furthermore, the surface of the drop-down area is sequentially paved with a leveling layer, a waterproof layer and a protective layer.

[0022] Furthermore, the high-zone drainage area and the low-zone drainage area are separated by a roof anti-ridge.

[0023] Furthermore, the formed drop-plate roof does not undertake the drainage work, and the drainage gutter is responsible for the drainage working conditions. The drainage gutter receives the filtered rainwater and flows it into the high-level drainage area. A connecting channel is set in the high-level drainage area to allow rainwater that exceeds the water storage capacity of the high-level drainage area to flow into the low-level drainage area through the connecting channel for roof drainage.

[0024] Furthermore, the standing seam metal roof and the permeable sheet material are fixed on the drop-down roof by a bottom supporting structure.

[0025] Furthermore, a single-volume building may have two or more structural roofs with different slopes and directions. Due to the characteristics of the roofs, rainwater on the roofs will flow unorganizedly to the lower part of the roofs.

[0026] The irregular slope roof is regarded as multiple single slope roofs with zoned drainage from a decomposed perspective. The structures of each structural roof are the same, and are all equipped with roof panels, perforated panels, drop-down panels and drainage gutters. The high-zone drainage area and the low-zone drainage area are connected by connecting grooves.

[0027] Furthermore, the drop-down roof, the drainage gutter and the roof anti-slope structure are poured with concrete at one time during the construction period.

[0028] Compared with the prior art, the device of the present invention has at least the following beneficial effects:

[0029] ① The invention is simple to construct, with integrated casting, drop-down roof, drainage gutter, and good roof integration. The roof is integrated into two heights to reduce the difficulty of construction.

[0030] ② The present invention adopts a slope treatment method, which can regard the irregular slope roof as a combination of multiple single-slope roofs, and performs graded drainage treatment based on the slope of each single-slope roof, which effectively solves the problem of organized drainage of irregular slope roofs without changing the roof image.

[0031] ③ The present invention can use the vertical lock-edge metal roof and the permeable board to replace the concrete roof for the initial drainage and filtration of water flow, reducing the drainage burden of the concrete roof. It also prevents the drainage area from being blocked by large-sized debris, reducing the maintenance cost.

[0032] ④ The concrete roof of the present invention uses two-level drainage elevation to divide drainage into zones, which greatly enhances the ability of this type of slope roof to organize drainage areas, temporarily store water, and efficiently drain water. It can achieve the function of timely drainage in areas with abundant rainfall in my country and reduce the maintenance cost of building facades.

[0033] ⑤ The vertical lock-edge metal roof of the present invention can be made of weather-resistant materials. While taking on the roof graded drainage, it protects the roof structure layer to reduce its risk of erosion and improves the weather resistance of the roof. The material and the same color and texture as the design language can enrich the fifth facade design image of the city and integrate the building facade image. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0045] The terms "include", "comprising" or any other variation thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or apparatus. In the absence of more restrictions, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, commodity or apparatus comprising the element.

[0046] In addition, in the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0047] The present invention adopts a drop-down roof, a vertical lock-edge metal roof and a permeable plate to form an organized drainage and drainage system for irregular slope roofs. The irregular slope roof includes two or more single-slope roofs. The slope and direction of the single-slope roofs can be different, and the structure of each single-slope roof is the same. Figure 1 The scope of irregular slope roofs is defined, which includes irregular slope roof prototypes, flat slope combined with irregular slope roofs, centripetal irregular slope roofs, combined irregular slope roofs and other forms.

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

[0049] The vertical lock seam metal roof and water-permeable sheet 1 comprises a 0.7 mm thick roof panel 101 and a 0.7 mm thick perforated sheet (r=5 mm aperture) 104, which are supported by a metal support 102, and the two are connected and fixed by no less than 4 bolts, and the size of the bolt 103 is 4M20. One side of the perforated sheet 104 overlaps the surface layer of the roof panel, and the other side is connected to the embedded angle piece of the concrete roof by bolts. The roof panel 101 and the perforated sheet 104 respectively play the role of initially guiding rainwater and filtering larger particle size debris.

[0050] The vertical lock seam metal roof and the permeable board receive and guide rainwater through the roof panel 101 of the covered roof, and then filter the rainwater through the perforated plate 104 to the drainage gutter directly below.

[0051] In some embodiments of the present invention, the perforated plate 104 is an aluminum plate, and the roof panel 101 is a titanium zinc roof panel. The galvanized roof panel has corrosion resistance and weather resistance, and the replacement frequency is very low. It can replace the original method of relying on the slope drainage of the main roof structure to further reduce the cost of the later maintenance of the slope roof building.

[0052] The drop-down roof 2 is made of reinforced concrete. A leveling layer 202, a waterproof layer and a protective layer 205 are laid on the upper part of the drop-down area. In one embodiment of the present invention, two waterproof layers are laid, including a first waterproof layer 203 and a second waterproof layer 204.

[0053] In some embodiments of the present invention, the keel is a keel frame 301 made of light steel for roofing, which is welded with galvanized square steel with a cross-sectional size of 100mm*100mm and a tube wall thickness of 5mm and has a spacing of 1200*1200. The ends of the keel frame 301 are welded with galvanized square steel (the same material as the light steel keel frame 301) and connected to the anti-slope embedded parts 303 of the main structure of the sloping roof. The upper part of the light steel keel frame 301 receives purlins 302 of 30*30 galvanized square steel. The keel frame 301 is used to receive the upper 0.7mm thick roof panel 101.

[0054] The drainage gutter 4 is formed by integrally pouring reinforced concrete together with the slope roof and the drop-down roof, and a waterproof layer and a protective layer are laid on the surface of the drainage gutter 4 in sequence.

[0055] The connecting groove 5 connects the high-area drainage area 6 and the low-area drainage area 7, and the main structure is cast together with the drop-down roof 2.

[0056] The high area drainage area 6 is coplanar with the drop plate area and separated by the roof anti-slope. The high area drainage area 6 is located at the lowest relative height of the drainage gutter 4 and is the collection area for rainwater diversion of the drainage gutter 4. The surface is laid with a waterproof layer and a protective layer in sequence.

[0057] The low-zone drainage area 7 is coplanar with the drainage gutter 4 and is separated by the anti-ridge where the connecting groove 5 is located. The low-zone drainage area 7 is located at the lowest relative height of each single roof drainage area. The surface is laid with a waterproof layer and a protective layer in sequence.

[0058] The downpipe system includes a downpipe 8 and a downpipe 9. The high-level drainage area 6 and the low-level drainage area 7 are each connected to a downpipe 8. Each downpipe guides rainwater into the municipal rainwater pipe through the downpipe 8. The downpipe 8 and the downpipe 9 are connected by a double-pass sleeve. The downpipe 9 is clamped by a pipe fixing part, and the pipe fixing part is nailed into the building wall by an expansion bolt. In some embodiments of the present invention, the downpipe 9 is a PVC pipe.

[0059] Working principle: The reinforced concrete slope roof partition drainage roof structure system forms the main structure through the integrated cast drop plate structure roof gutter drainage trough. The upper part uses the keel frame 3 to support the upright lock edge metal roof and the permeable plate 1, which greatly enhances the ability of this type of slope roof to organize and plan drainage areas, temporarily store water, and efficiently drain water. Under the gravity effect formed by the slope of the upright lock edge metal roof and the permeable plate 1 with the same slope as the covered roof, the roof panel 101 uses the slope to preliminarily guide the direction of roof rainwater, and the perforated plate 104 uses the perforations to intercept and filter large-sized debris. The anti-interference ability and efficient drainage efficiency of the organized drainage of the slope roof are enhanced, while the difficulty and labor cost of later maintenance and cleaning of the slope roof are reduced. The drainage gutter 4 receives filtered rainwater, and uses its own slope to direct rainwater runoff to the high-area drainage area 6, and a small part of the runoff to the low-area drainage area 7. At this time, the high-area drainage area 6 is mainly responsible for roof drainage, and the low-area drainage area 7 is auxiliary for roof drainage, which strengthens the roof drainage capacity in areas with abundant rainfall. At the same time, the high-area drainage area 6 and the low-area drainage area 7 are connected at a high water level through the connecting groove 5, which can avoid the phenomenon of unorganized drainage caused by the high-area drainage area 6 being unable to drain 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 described examples are only technical solutions of the present invention, and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it should be understood by those skilled in the art that some of the devices or elements described in the aforementioned embodiments may still be replaced by equivalents, or their sizes may be changed, and these modifications or replacements do not deviate from the essence of the corresponding technical solutions within the scope of the technical solutions of the various embodiments of the present invention.
