Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a metal roof without gutters for water collection. Background Technology

[0002] Currently, traditional metal decorative roofs typically require exposed metal gutters at the eaves as the primary drainage structure. Rainwater naturally collects in the gutters along the roof slope, then flows through them into the downpipes and ultimately into the drainage system. However, eaves gutters must meet strict dimensional requirements, resulting in a heavy and protruding eaves area, poor roof aesthetics, and disrupting the unified visual effect of the building facade. Furthermore, eaves gutters require cantilever construction at heights, demanding high levels of worker skill and increasing the risk of falls or material spills. Exposed gutters are also constantly exposed to ultraviolet radiation, acid rain, and temperature fluctuations, leading to coating peeling, metal corrosion, and even structural deformation, increasing maintenance work and costs. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a metal roof without gutters, which can improve the aesthetics of the roof design, reduce construction difficulty and later maintenance costs.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A gutterless metal roof includes tiles and a mounting frame. The mounting frame is inclined from one side of the building roof towards the cantilever beam. The tiles include tile one and tile two. Tile two is laid on the top of the mounting frame near the eaves of the metal roof, while tile one is laid on the rest. Tile one is spaced apart along the inclined direction of the mounting frame, and the bottom tile one is also spaced apart from tile two. The through gaps between two adjacent tile one and the through gaps between the bottom tile one and tile two respectively form water flow channels. A snow deflector is also installed on the mounting frame near the eaves of the metal roof.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This utility model leaves horizontal through gaps between the tiles, allowing rainwater to naturally disperse and drain along the roof slope to the building roof, where it is then centrally drained away by the roof's drainage pipes. This eliminates the need for traditional eaves gutters, reducing construction difficulty and costs, and enhancing the aesthetics of the roof design.

[0008] As a preferred embodiment, a further technical solution of this utility model is:

[0009] Preferably, the mounting frame includes a fixed frame and an inclined beam placed above the fixed frame. There are at least two inclined beams, which are connected by support rods. The support rods are spaced apart along the inclination direction of the inclined beams. Tile one, tile two, and snow deflector are respectively connected to the support rods at their corresponding positions.

[0010] Preferably, one end of tile 1 is provided with an outer eave structure, and the other end is provided with a sloping structure. The outer eave structure of the lower tile 1 in two adjacent tiles 1 is placed outside the upper sloping structure.

[0011] Preferably, a guide plate is also provided between the parapet wall of the building roof and the cantilever beam. One end of the guide plate is connected to the mounting frame, and the other end is connected to the parapet wall of the building roof.

[0012] Preferably, an electric heating tape is provided on the bottom surface of the second tile.

[0013] Preferably, the mounting bracket is provided with a metal base plate corresponding to the position of each tile 2, and the gap between the metal base plate and the tile 2 is filled with thermal insulation cotton.

[0014] Preferably, the width of the through seam is 50-100mm. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0021] A metal roof without gutters for water collection consists of a mounting frame and tiles. The mounting frame is inclined from the building roof 1 toward the cantilever beam 2 (i.e., one end of the roof is higher than the other end of the cantilever beam). The mounting frame consists of a fixing frame 3 and an inclined beam 4 placed above the fixing frame 3. Connectors that connect to the fixing frame 3 are pre-embedded at the parapet wall 5, cantilever beam 2, and other locations on the building roof 1. The fixing frame 3 is connected and fixed to the parapet wall 5 and cantilever beam 2 through the connectors.

[0022] At least two inclined beams 4 are arranged in parallel. One end of the inclined beam is connected to the fixed frame 3, and the other end is connected to the pergola beam 14 above the building roof. The inclined beams 4 are connected by support rods 6 placed on the top of the inclined beams 4. The support rods 6 are welded to the inclined beams 4, and the support rods 6 are spaced apart along the inclination direction of the inclined beams 4. Tile 1 7, tile 2 8 and snow deflector 13 are respectively connected to the support rods 6 at the corresponding positions.

[0023] The roof tiles consist of tile 7 and tile 8, both made of metal. Tile 7 and tile 8 are laid on the top of the mounting frame near the eaves, while tile 7 is laid in the remaining areas. In this embodiment, tile 7 is laid at intervals along the inclined direction of the diagonal beam 4, and each tile 7 is laid laterally between two diagonal beams 4. Several tiles of tile 8 are laid along the length of the support rod 6, with adjacent tiles of tile 8 overlapping.

[0024] The through gaps between two adjacent tiles 7 and the through gap between the bottom tile 7 and tile 8 form water flow channels 9, with the width of the through gaps being 50-100mm.

[0025] The end of tile 7 furthest from the cantilever beam 2 is bent to form an outer eave structure 701, and the end closest to the cantilever beam 2 is bent to form a sloping structure 702. The outer eave structure 701 of the lower tile 7 is placed outside the sloping structure 702 of the upper tile 7.

[0026] The two ends of tile 7 are bent to form the outer eaves structure 701 and the sloping structure 702, respectively, which increases the rigidity of tile 7 and reduces the material thickness. The thickness of conventional metal roofing tiles is 2.5mm, but by optimizing the tile style, the thickness of the tile can be optimized to 1.5mm. At the same time, the upper corner visually covers the horizontal seam between tiles 7, enhancing the overall aesthetic effect.

[0027] The bottom surface of tile 28 is covered with an electric heating cable, which is laid at intervals along the length of the support rod 6, with a spacing of 150mm.

[0028] The surface of tile 2 (8) is also equipped with a rain and snow sensor. The electric heating cable is connected to a power junction box, and the power junction box and the rain and snow sensor are respectively connected to a controller inside the temperature control distribution box. The rain and snow sensor automatically detects snowfall signals, and the controller activates the heating of the electric heating cable to melt the snow on tile 2. (The snow melting technology using electric heating cable is existing technology and will not be described in detail here.)

[0029] The mounting bracket is connected to a metal base plate 10 corresponding to the area where the second tile 8 is laid. In this embodiment, the metal base plate 10 is an aluminum plate. The cavity formed between the metal base plate 10 and the second tile 8 is filled with thermal insulation cotton 11. In this embodiment, the thermal insulation cotton 11 is 40mm thick aluminum foil-coated glass fiber thermal insulation cotton 11.

[0030] A guide plate 12 is also fixedly connected to the fixed frame 3. The guide plate 12 is placed between the parapet wall 5 and the cantilever beam 2 of the building roof 1. The guide plate 12 is a guide structure with a slope formed by bending steel plate. The top of the guide plate 12 is connected to the support rod 6 on the upper part of the tile 2 by screws. The bottom of the guide plate 12 is fixedly connected to the side of the parapet wall 5 away from the cantilever beam 2. Rainwater falls along the water flow channel 9 and is concentrated and guided to the building roof 1 by the guide plate 12, and then discharged by the drainage system on the building roof 1.

[0031] In this embodiment, the joint between the guide plate 12 and the bottom of the tile 2 is sealed tightly with silicone sealant.

[0032] In practical applications, this device involves laying metal roofing sheets (such as...) at the locations of the cantilever beams 2 around the building's roof 1. Figure 4 As shown, rainwater falls onto tile 7 and flows along the slope of tile 7. The rainwater from the metal roof is naturally dispersed to the building roof 1 through the water flow channels 9 left between the tiles, and then discharged by the drainage system of the building roof 1. Snow deflectors 13 and electric heating tapes are installed near the eaves. In winter, the electric heating tapes are used to melt snow, effectively preventing snow from sliding and accumulating, and ensuring the safety of the roof.

[0033] This utility model utilizes water flow channels left between tiles to disperse rainwater and discharge it into the building's roof drainage system. It eliminates the need for metal gutters, reducing construction difficulty and saving construction costs, while also improving the aesthetics of the building's design. Snow deflectors and snow melting structures are added near the eaves to prevent snow from accumulating and sliding off, thus improving the safety of the building structure.

[0034] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
