Detailed Description

The technical solutions of the present application will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application discloses roofing vertical lock seam connection structure. Referring to fig. 1, the roof upright locking seam connecting structure comprises a first panel 1, a second panel 2 and a positioning rod 31, wherein a second arch ring 21 used for being sleeved at the upper end of the positioning rod 31 is arranged on the second panel 2, and a first arch ring 11 used for being sleeved outside the second arch ring 21 is arranged on the first panel 1; still including being used for installing mounting panel 41 and the connecting plate 32 of rigid coupling at the locating lever 31 lower extreme on the roofing, locating lever 31 just is "T" style of calligraphy setting with connecting plate 32 is perpendicular, and mounting panel 41 runs through all around and has seted up a plurality of mounting holes.

Referring to fig. 1 and 2, a protruding portion 42 is upward arranged in the middle of the mounting plate 41, the distance between the bottom wall of the protruding portion 42 and the bottom wall of the mounting plate 41 is matched with the thickness of the connecting plate 32, an accommodating cavity 43 for accommodating the connecting plate 32 is formed below the protruding portion 42, one end of the accommodating cavity 43 is opened, an adjusting groove 44 is formed in the protruding portion 42 in a penetrating mode, the adjusting groove 44 is arranged along the protruding portion 42 in a tendency mode, one end of the adjusting groove 44 is communicated with the opening end of the accommodating cavity 43, and the lower end of the positioning rod 31 is matched with the adjusting groove 44 in a sliding mode, and the length of the adjusting groove 44 is larger than the width of the lower portion of the positioning rod 31.

Therefore, when the roof panel is installed, the installation plate 41 is installed on a roof, the positioning rod 31 is inserted into the adjusting groove 44 so that the connecting plate 32 is embedded into the installation cavity 43, then the first panel 1 and the second panel 2 are arranged on two sides of the positioning rod 31 in a split mode, the second arch-shaped ring 21 is wrapped on the upper end of the positioning rod 31, the first arch-shaped ring 11 is wrapped outside the second arch-shaped ring 21 and then locked with the first arch-shaped ring 11, at the moment, the first panel 1 and the second panel 2 are tightly locked and sewn on the positioning rod 31, and good waterproof performance can be achieved. Therefore, when the roof panel deforms due to thermal expansion and cold contraction, the lower part of the positioning rod 31 can slide in the adjusting groove 44, a certain deformation space can be provided, and the deformation phenomenon of the roof panel is effectively avoided.

Further, referring to fig. 1 and 2, the protruding portion 42 is provided with an elastic limiting member at an opening end thereof, the elastic limiting member includes an elastic body 51 and a limiting plate 52 fixedly connected thereto, the limiting plate 52 is a metal plate or a rigid plastic plate, and in this embodiment, the limiting plate 52 is provided as a metal plate; the elastic body 51 is provided as a rubber block, and in other embodiments, a plurality of through holes may also be vertically perforated on the elastic body 51 to increase the deformation space of the elastic body 51.

Two ends of the limiting plate 52 protrude out of two opposite sides of the elastic body 51, the elastic body 51 is embedded and matched with the adjusting groove 44, the upper end face of the protruding part 42 close to the opening end of the protruding part penetrates through the limiting groove 53 communicated with the mounting cavity 43, and the limiting groove 53 extends to two sides of the adjusting groove 44 in the width direction and is inserted and matched with the part of the limiting plate 52 protruding out of the elastic body 51; and the distance between the groove wall of the adjusting groove 44 far away from the opening end and the elastic body 51 is still larger than the dimension of the positioning rod 31 along the length direction of the adjusting groove 44.

Therefore, after the positioning rod 31 is installed, the limiting plate 52 is inserted into the limiting groove 53, the elastic body 51 is located on one side, close to the positioning rod 31, of the limiting plate 52, when the roof panel deforms due to the influence of expansion with heat and contraction with cold, the lower portion of the positioning rod 31 slides in the adjusting groove 44, the connecting plate 32 slides in the arranging cavity 43, and a sufficient space can be provided for deformation of the roof panel, so that the roof panel is prevented from deforming. When the deformation volume of roof boarding is too big, connecting plate 32 butt on elastomer 51, and elastomer 51 takes place deformation, can improve certain buffering for the deformation of roof boarding to prevent that locating lever 31 from excessively rocking and influencing the holistic stability of roof boarding in adjustment tank 44, limiting plate 52 can provide limiting displacement to elastomer 51 after pegging graft with spacing groove 53. To prevent the elastic body 51 from being ejected by the positioning rod 31 to lose the cushioning effect of the elastic body 51.

However, the elastic body 51 is required to provide different buffering effects based on different temperature differences in different regions, and referring to fig. 2, a plurality of limiting grooves 53 are formed along the length direction of the adjusting groove 44.

In order to further improve the lock seam strength of the first panel 1 and the second panel 2 on the positioning rod 31, referring to fig. 1, a positioning head 33 is fixedly connected to the upper part of the positioning rod 31, and a notch 34 for embedding the free end of the first arched ring 11 is formed in the lower part of the positioning head 33 close to the positioning rod 31. Therefore, when the first arched ring 11 and the second arched ring 21 are subjected to seam locking through the seam locking machine, the second arched ring 21, the connecting plate 32 of the second panel 2 and the free end of the first arched ring 11 are embedded into the notch 34, the first arched ring 11 and the second arched ring 21 can be locked more tightly, and meanwhile, the free end of the first arched ring 11 located outside is not easy to generate the phenomena of unwinding and upwarping.

The implementation principle of the roof upright lock seam connecting structure in the embodiment of the application is as follows: when the roof panel is installed, the installation plate 41 is installed on a roof, the positioning rod 31 is inserted into the adjusting groove 44 so that the connecting plate 32 is embedded into the installation cavity 43, then the first panel 1 and the second panel 2 are arranged on two sides of the positioning rod 31 in a split mode, the second arch-shaped ring 21 is wrapped on the upper end of the positioning rod 31, the first arch-shaped ring 11 is wrapped outside the second arch-shaped ring 21 and then locked with the first arch-shaped ring 11, at the moment, the first panel 1 and the second panel 2 are tightly locked and sewn on the positioning rod 31, and good waterproof performance can be achieved. Therefore, when the roof panel deforms due to thermal expansion and cold contraction, the lower part of the positioning rod 31 can slide in the adjusting groove 44, a certain deformation space can be provided, and the deformation phenomenon of the roof panel is effectively avoided.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
