Description

Technical Field

[0001] This utility model relates to the technical field of telescopic flashing devices, and in particular to a telescopic flashing device for roofs. Background Technology

[0002] Flashing is a type of metal waterproof component that has undergone anti-corrosion treatments such as galvanizing, aluminum-zinc coating, aluminum-zinc-magnesium coating, and paint coating. It is mainly used for waterproofing protection of building roof edges, parapet walls, and other areas. Its core functions include guiding rainwater to the drainage system, preventing rainwater from eroding the walls and causing leaks, and improving overall sealing performance through a combination of folded edge splicing structure and sealing strips.

[0003] Due to limitations in equipment processing dimensions (generally within 6m) and the thermal expansion and contraction characteristics of materials, and the fact that ridges are typically tens to hundreds of meters long, flashing at the ridge cannot be made in a single piece. Longitudinal overlap of the flashing panels is unavoidable. Under the influence of wind disturbance and thermal expansion and contraction, the flashing is easily torn at the nailing points, leading to potential leaks and safety hazards. Therefore, a retractable device for roof flashing needs to be designed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a retractable roof flashing device that is easy to connect and releases the stress caused by thermal expansion and contraction.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a lower connecting block, one end of which is fixedly connected to the mounting block through a first locking member, and the other end of which forms a sliding groove; an upper connecting block, one end of which is slidably connected to the sliding groove, and the other end of which is fixedly connected to the flashing through a second locking member, and the flashing is slidably engaged with the roof panel.

[0006] Furthermore, the lower connecting block is formed with a slider that slides in conjunction with the groove, and the slider is in the shape of an inverted "T".

[0007] Furthermore, the groove is a T-shaped groove.

[0008] Furthermore, the lower connecting block has a first mounting plate, and the first locking member passes through the first mounting plate and is fixedly connected to the roof panel. The upper connecting block has a second mounting plate, and the second locking member passes through the second mounting plate and is fixedly connected to the flashing.

[0009] Furthermore, the upper surface of the first mounting plate is formed with a first locking tooth for increasing friction, and the first locking tooth fits tightly with the first locking member; the lower surface of the second mounting plate is formed with a second locking tooth for increasing friction, and the second locking tooth fits tightly with the second locking member.

[0010] Furthermore, the first locking member and the second locking member are self-tapping screws or rivets.

[0011] Furthermore, an installation block is provided between the lower connecting block and the roof panel, and the installation block is fixedly connected to the roof panel.

[0012] The beneficial effects of this utility model are: the upper connecting block and the lower connecting block of this utility model form a movable structure through the sliding groove. When the flashing expands and contracts with heat, it moves along the direction of the sliding groove to release the displacement caused by the change in shape. This avoids the flashing being damaged due to the inability to release the stress caused by thermal expansion and contraction, which would affect the structural safety and waterproof performance of the flashing.

[0013] When the first locking tooth of the upper connecting block and the second locking tooth of the lower connecting block are locked and fixed using the first locking member and the second locking member, the first locking tooth is in close contact with the lower surface of the locking part of the first locking member, and the second locking tooth is in close contact with the lower surface of the locking part of the second locking member, thereby increasing the locking friction and improving the locking stability.

[0019] like Figures 1 to 4 As shown, in this embodiment, the present invention includes a lower connecting block 4, one end of which is fixedly connected to the mounting block 3 via a first locking member 6, and the other end of which forms a sliding groove 41; and an upper connecting block 5, one end of which is slidably connected to the sliding groove 41, and the other end of which is fixedly connected to the flashing 2 via a second locking member 7, and the flashing 2 is slidably engaged with the roof panel 1.

[0020] Specifically, the two ends of the slide groove 41 are open T-shaped grooves, which facilitates the insertion of the upper connecting block 5 from the side, improving the convenience of installation and disassembly. The upper connecting block 5 and the lower connecting block 4 form a movable structure through the slide groove 41. When the flashing plate 2 expands and contracts with heat, it moves along the direction of the slide groove 41 to release the displacement caused by the change in shape, and avoids damage to the flashing plate 2 due to the inability to release the stress formed by thermal expansion and contraction, which would affect the structural safety and waterproof performance of the flashing plate 2. When the first locking tooth 44 of the upper connecting block 5 and the second locking tooth 54 of the lower connecting block 4 are locked and fixed by the first locking member 6 and the second locking member 7, the first locking tooth 44 is close to the lower surface of the locking part of the first locking member 6, and the second locking tooth 54 is close to the lower surface of the threaded section of the second locking member 7, which increases the locking friction and improves the locking stability.

[0021] In this embodiment, the upper connecting block 5 is formed with a slider 51 that slides with the groove 41, and the slider 51 is in the shape of an inverted "T".

[0022] In this embodiment, the groove 41 is a T-shaped groove.

[0023] In this embodiment, the lower connecting block 4 is formed with a first mounting plate 42, and the first locking member 6 passes through the first mounting plate 42 and is fixedly connected to the roof panel 1. The upper connecting block 5 is formed with a second mounting plate 52, and the second locking member 7 passes through the second mounting plate 52 and is fixedly connected to the flashing 2.

[0024] In this embodiment, the upper surface of the first mounting plate 42 is formed with a first locking tooth 44 for increasing friction, and the first locking tooth 44 is in close contact with the first locking member 6. The lower surface of the second mounting plate 52 is formed with a second locking tooth 54 for increasing friction, and the second locking tooth 54 is in close contact with the threaded section of the second locking member 7.

[0025] When the first locking member 6 and the second locking member 7 are used to lock and fix the first locking tooth 44 of the upper connecting block 5 and the second locking tooth 54 of the lower connecting block 4, the first locking tooth 44 is in close contact with the lower surface of the locking part of the first locking member 6, and the second locking tooth 54 is in close contact with the lower surface of the locking part of the second locking member 7, thereby increasing the locking friction and improving the locking stability.

[0026] In this embodiment, the first locking member 6 and the second locking member 7 are self-tapping screws or rivets.

[0027] In this embodiment, an installation block 3 is provided between the lower connecting block 4 and the roof panel 1, and the installation block 3 is fixedly connected to the roof panel 1.

[0028] The function of mounting block 3 is to seal the gap between roof panel 1 and lower connecting block 3, thereby improving the tightness of the connection.

[0029] The working principle of this utility model:

[0030] The first locking member 6 fixes the lower connecting plate to the roof panel 1. The slider 51 of the upper connecting plate is inserted into the groove 41 from the side. Then, the second locking member 7 passes through the flashing 2 from top to bottom and locks and fixes itself to the second connecting plate. When locking, the lower surface of the locking part of the first locking member 6 is close to the first locking tooth 44, and the threaded section of the second locking member 7 is close to the second locking tooth 54. When the flashing 2 expands and contracts with heat, the displacement causes the upper connecting member 5 to move back and forth along the direction of the groove 41 to eliminate stress.

[0031] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
