The present invention relates to a connection structure of a prefabricated panel for a roof, and more particularly, to provide a structure to clip to each other when fixedly mounted to the roof structure by mutually bonding adjacent metal cladding panels for each other. The present invention relates to a connection structure of a prefabricated panel for a roof that can secure ease and simplicity, is easy to maintain, has excellent waterproof function, and can flexibly respond to changes in external temperature.

As exterior materials of the roof (ROOF) of the building, exterior panels (PANEL) having various structures and materials are used. These panels are mounted in tightly bonded joints on the roof's purins, which require joining means such as metal strips or fastening clips for the joining and interconnection of the panels, depending on which panels are joined together. It requires joining structure or joining method with various shapes, and it takes a long time because it requires a lot of manpower and precision to connect and fix it on the roof in this way. Will be followed.

Conventional cross-panel connection method uses a joint cap as a tightening means by simply overlapping the two panels, and also fastens directly to the structure by using fastening bolts. However, this method is susceptible to changes in the external temperature, and there is a risk of leakage due to gaps in the joints due to expansion and expansion of the panel, and it is difficult to use in low inclined roofs.

In addition, a standing seaming method is also used as a panel connection method, which is a method of connecting the joints with clips by watertight caulking. However, according to this method, a separate finishing machine (seaming machine) is required, which increases the cost and hassle of construction, and after construction, it is difficult to replace or release work, and the ribs are formed in the longitudinal direction of the panel, There is a problem that stiffness cannot be guaranteed.

In order to overcome this problem, a panel connection structure having an improved structure has been filed and registered in Korea a number of utility model No. 208231 is a spring for supporting the fixing bolt for fixing the baton bar and baton cap connecting each panel The nut is characterized by tighter connection between the panels, but according to this technology, the construction cost can be increased due to the complexity of the components, and the fixing bolt is exposed to the outside, which is not good for appearance, There is a problem that a leak may occur between the assemblies.

In addition, according to the Utility Model Registration No. 134666, by continuously bending the engaging portion of the panel to form a locking jaw and a locking groove, and providing a way to fit the other panel by the locking jaw, the locking groove (sliding system) There is an advantage that the construction is easy and insulation is ensured in a simple manner, but when combined with the structure of the locking jaw and the locking groove, the coupling may be easy, but there is a problem in ensuring the rigidity of the coupling, and thus there is room for structural improvement.

The present invention has been devised to overcome these problems, it is equipped with a connecting structure to help the sliding coupling or clip coupling to each other by the manpower on both sides of the panel without a separate equipment to combine more easily while reducing the cost with a simple configuration It is an object of the present invention to provide a connection structure that can guarantee a strong and tight coupling between panels.

Another object of the present invention is to provide a connection structure through a separate bracket to ensure the bonding force between the panel and the lower structure or gable.
