Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to an eaves limiting mechanism and a metal roof. Background Art

[0002] At present, some large industrial plants or temporary buildings on the market use corrugated metal roof panels as roofs. Usually when installing metal roof panels, the wind resistance and waterproof ability of the panels are taken into consideration, especially at the eaves. The wind pressure at the eaves is greater than other parts of the metal roof. It is also the gathering place of rainwater. Even if the roof surface is inclined, the rainwater collected at the eaves will be blown into the eaves under the action of strong winds, causing leaks in the house.

[0003] In addition, during the installation process, since the metal roof panels are not positioned in the width direction, they are often fixed based on the workers' experience to select the fixing points, resulting in poor installation accuracy in the width direction of the metal roof panels. Utility Model Content

[0004] In view of the above problems, an embodiment of the utility model is proposed. One purpose of the embodiment of the utility model is to provide a metal roof surface that can prevent rainwater from entering the eaves, improve the wind resistance of the eaves, and is easy to install and can control the installation accuracy of the roof panels.

[0017] Preferably, a plurality of the locking members are arranged at intervals on the mounting surface.

[0018] Preferably, the limiting bracket group comprises a plurality of limiting brackets connected in sequence, and the eaves plug is arranged on the limiting brackets.

[0019] Preferably, the limiting bracket has a lap hole at one end and a lap plate at the other end.

[0020] Another object of the embodiment of the utility model is to provide a metal roof with strong wind resistance at the eaves, no rain leakage, easy installation, and high roof panel installation accuracy.

[0021] To achieve this purpose, the present invention adopts the following technical solutions:

[0037] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0041] Figure 1 This is a schematic diagram of the structure of the eaves limiting mechanism and the metal roof panel provided in one embodiment of the utility model. Figure 1 A schematic diagram of the structure of the eaves limiting mechanism provided in one embodiment of the utility model is shown in FIG. Figure 1 and Figure 2 shown.

[0042] The present embodiment provides a metal roof, which includes a purlin keel, a metal roof panel 20 arranged on the purlin keel, and an eaves limiting mechanism 10 arranged on the purlin keel, wherein the metal roof panel 20 is covered on the eaves limiting mechanism 10, and the eaves limiting mechanism 10 can block the eaves of the metal roof panel 20 to reduce the wind pressure at the eaves, improve the wind resistance of the metal roof panel 20, and can also prevent water gathered at the eaves from flowing into the room through the eaves, causing rain leakage in the house.

[0043] It is understandable that since the metal roof panel 20 is a relatively large plate with low structural strength, it is easy to deform under the action of external force. In order to increase the strength of the metal roof panel 20 and ensure the aesthetics of the metal roof panel 20, a plurality of medium wave peaks are often arranged at intervals on the metal roof panel 20, and these medium wave peaks form cornices at the edges of the roof panel along the width direction. The cornice sizes of different metal roof panels 20 are different, and some metal roof panels 20 have different sizes of medium wave peaks for some reasons, which results in different cornice sizes of the same metal roof panel 20. In addition, if a plurality of cornice plugs 200 are used to block the corresponding cornices after the metal roof surface is installed on the purlin keel, it is difficult to assemble, time-consuming and labor-intensive.

[0044] To solve the above problems, please refer to Figure 2 In some achievable embodiments of the present invention, one achievable manner of the eaves limiting mechanism 10 is that the eaves limiting mechanism 10 includes a limiting bracket group 100 and an eaves plug 200, wherein the limiting bracket group 100 is arranged on the purlin keel, and multiple eaves plugs 200 of different models or the same model are arranged at intervals on the limiting bracket group 100, and the position and shape of the eaves plug 200 match the eaves at the corresponding position of the metal roof panel 20, so that the eaves limiting mechanism 10 can be applied to different metal roof panels 20, and has a wide range of uses. The eaves limiting mechanism 10 can be installed before leaving the factory, that is, the model of the applicable eaves plug 200 is selected according to the matching metal roof panel 20, and the eaves plug 200 is pre-installed on the limiting bracket group 100 according to the position of the eaves of the metal roof panel 20, and the length of the limiting bracket group 100 matches the width of the metal roof panel 20. Therefore, before the metal roof panel 20 is installed on the purlin keel, the eaves limiting mechanism 10 can be installed on the purlin keel first, and then the metal roof panel 20 can be installed. This is not only convenient for installation, but also saves time and effort. In addition, the eaves plug 200 can serve as a limiting piece for the metal roof panel 20 in the width direction, thereby ensuring the installation accuracy of the metal roof panel 20.

[0045] Figure 3 For a schematic diagram of the structure of the cornice plug provided by an embodiment of the utility model, please refer to Figure 3 .

[0046] Specifically, in some achievable embodiments of the present invention, one achievable structure of the eaves plug 200 is that the eaves plug 200 includes a blocking surface 210 and a mounting surface 220, wherein the blocking surface 210 follows the shape of the eaves to block the eaves, and each boundary of the blocking surface 210 has a mounting surface 220, a portion of the mounting surface 220 is connected to the eaves, and another portion of the mounting surface 220 is connected to the limit bracket group 100. In order to ensure the sealing of the eaves by the eaves plug 200, the mounting surface 220 located below the eaves plug 200 is in contact with the limit bracket group 100, and the mounting surface 220 located above is in contact with the metal roof surface at the eaves. That is, the circumferential eaves walls of the eaves are all connected with the mounting surface 220, so that the blocking surface 210 can fully block the eaves and ensure good wind resistance.

[0047] For further information, please refer to Figure 1 In order to avoid a gap between the eaves plug 200 and the eaves, as an achievable embodiment, a seal 300 is provided between the mounting surface 220 and the metal roof surface and between the mounting surface 220 and the limiting bracket group 100, so that the eaves plug 200 and the eaves have good sealing. As an optional solution, the seal 300 is a butyl tape, and the butyl tape has adhesive glue on both sides, which can not only achieve a watertight and airtight sealing effect, but also achieve a connection between the metal roof panel 20 and the eaves plug 200 and between the limiting bracket group 100 and the eaves plug 200. The structure is simple, the cost is low, and the connection between the metal roof panel 20 and the eaves plug 200 can be achieved without opening holes between the metal roof panels 20, thereby avoiding damage to the sealing of the metal roof panel 20.

[0048] Furthermore, the entire strip of butyl tape is pasted from one end of the limiting bracket group 100 along the length direction of the limiting bracket group 100, covering the mounting surface 220 where the eaves plug 200 is connected to the metal roof surface, until it is pasted to the other end of the limiting bracket group 100, thereby ensuring good sealing between the eaves limiting mechanism 10 and the metal roof surface.

[0049] Since the sizes of the eaves of different metal roof panels 20 are different, some of the eaves are relatively large, and the corresponding eaves plugs 200 are also relatively large, so the strength of the blocking surface 210 is relatively low and it is easy to be deformed by foreign objects. Therefore, as an optional solution, please refer to Figure 3 A plurality of reinforcing ribs 211 are arranged at intervals on the blocking surface 210 , thereby increasing the strength of the blocking surface 210 .

[0050] In order to further ensure the sealing performance of the eaves plug 200 and avoid the formation of a gap between the eaves plug 200 and the eaves, as an optional solution, the eaves plug 200 is a piece of plate material, which is stamped and formed so that the surface of the eaves plug 200 is continuous without any breaks, which not only has good sealing performance but also does not require subsequent sealing.

[0051] Figure 4 A side view of an eaves limiting mechanism provided in one embodiment of the utility model, Figure 5 For a top view of the eaves limiting mechanism provided in one embodiment of the utility model, please refer to Figure 4 and Figure 5 .

[0052] In order to make the connection between the eaves plug 200 and the limiting bracket group 100 more reliable, in some feasible embodiments of the present invention, the eaves limiting mechanism 10 further includes a locking member 400, which passes through the mounting surface 220 and is connected to the limiting bracket group 100 to lock the eaves on the limiting bracket group 100. In addition to being bonded, the eaves plug 200 and the limiting bracket group 100 are also screwed and fixed, so that the connection between the eaves plug 200 and the limiting bracket group 100 is more stable.

[0053] Furthermore, as an optional solution, a plurality of locking members 400 are arranged at intervals on the mounting surface 220 so that the connection between the eaves plug 200 and the limiting bracket group 100 is more reliable. In the present embodiment, each eaves plug 200 is connected to the limiting bracket group 100 via two locking members 400 so that the eaves plug 200 will not shift relative to the limiting bracket group 100.

[0054] In some achievable embodiments of the present invention, a achievable structure of the limit bracket group 100 is that the limit bracket group 100 includes a plurality of limit brackets 110 connected in sequence, and the eaves plug 200 is arranged on the limit bracket 110. The limit bracket group 100 can determine the number of limit brackets 110 according to the width of the unused metal roof panel 20, so that the width of the limit bracket group 100 can match the width of the metal roof panel 20, so that the eaves limit mechanism 10 has great flexibility, and the use of metal roof panels 20 of different widths has a wider range of uses.

[0055] For further information, please refer to Figure 4 In order to enable the ends of two adjacent limiting brackets 110 to be butted against each other and the limiting bracket group 100 to be evenly butted against the purlin keel, in some achievable embodiments of the present invention, one achievable manner of the limiting bracket 110 is that one end of the limiting bracket 110 has a lap hole and the other end has a lap plate, and the lap plate can pass through the lap hole and be connected to the lap hole.

[0056] Specifically, one possible structure of the lap hole is that two slits are spaced apart parallel to the width direction of the limit bracket 110, and the central part of the slit is the upper hole wall. The upper hole wall is bent toward the direction of installing the eaves plug 200, so that a transparent lap hole is formed between the upper hole wall and the limit bracket 110. After the lap plate passes through the lap hole, it is bent toward the direction of the metal roof panel 20 and then bent toward the upper hole wall until it abuts against the upper end of the upper hole wall, thereby realizing the connection between the upstream limit bracket 110 and the downstream limit bracket 110.

[0057] As another achievable embodiment, one end of the limiting bracket 110 has a lap groove and the other end has a lap plate, the opening direction of the lap groove is away from the eaves plug 200, and the lap plate at the end of the downstream limiting bracket 110 is bent toward the eaves plug 200 and can extend into the lap groove, thereby realizing the connection between two adjacent limiting brackets 110, with a simple structure and easy operation.

[0058] As long as the ends of two adjacent limiting brackets 110 can be aligned and connected, this embodiment does not make any specific limitation.

[0059] As an optional solution, in order to ensure the stability of the connection, one end of the limiting bracket 110 has two overlapping holes at intervals, and the other end thereof has two overlapping plates corresponding thereto, so as to avoid mutual displacement between the limiting brackets 110.

[0060] Understandably, please refer to Figure 4 and Figure 5 The edges of the purlin keel metal roof panel 20 in the width direction have a certain distance, and the edge of the metal roof panel 20 extending out of the purlin keel under the action of strong wind is more susceptible to the impact of wind. Therefore, in some achievable embodiments of the present invention, a achievable structure of the limiting bracket 110 is that one side of the limiting bracket 110 is connected to the purlin keel, and the other side extends to the edge of the metal roof panel 20. The eaves plug 200 is installed on the other side of the limiting bracket 110 to block from the edge of the metal roof panel 20, thereby reducing the force of strong wind on the metal roof panel 20 and ensuring the wind-resistant ability of the metal roof panel 20.

[0061] Further, as an achievable embodiment, please refer to Figure 5 In order to strengthen the limiting bracket 110 , a reinforcing edge 112 is extended from the other end of the limiting bracket 110 in a direction away from the eaves plug 200 , and a reinforcing rib or a bent reinforcing structure 111 is provided between the two sides of the limiting bracket 110 .

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
