Description

Cross roof anti-seepage structure Technical Field The application relates to the technical field of building roof boards, in particular to an anti-seepage structure of a crossed roof. Background In the design of building roof, the crossing part (such as ridge, gutter, etc.) of two pitched roof boards is easy to leak due to expansion with heat and contraction with cold, rain wash or construction error because of complex structure and more joints. The traditional solution is generally filled by adopting a simple sealant, and the traditional solution is easy to age and crack after long-term use and has poor waterproof effect. The metal flashing board is covered by welding or riveting, the construction is complex, and the expansion coefficients of the metal and the roof board are different, so that the metal flashing board is easy to deform and infiltrate. The common drainage tank is designed to drain rainwater on the surface only, and can not solve the capillary water seepage problem at the joint. Therefore, there is a need for a cross-roof leakage prevention solution that is simple in construction, strong in tightness and good in durability. Disclosure of utility model Based on the above, it is necessary to provide a cross roof leakage-proof structure, and the specific technical scheme is as follows. The utility model provides a cross roof antiseep structure, includes first pitched roof board and second pitched roof board, the below of first pitched roof board and second pitched roof board is equipped with heat preservation, screed, waterproof layer and noise reduction layer, the crossing arrangement in bottom of first pitched roof board and second pitched roof board, the bottom of first pitched roof board and second pitched roof board is equipped with the butt joint piece, both sides in the butt joint piece are equipped with the slot, the bottom of first pitched roof board and second pitched roof board can insert in the slot, be equipped with in the slot and wrap up U type rubber seal spare of first pitched roof board and second pitched roof board bottom, be equipped with locking structure between the both sides of butt joint piece and first pitched roof board, the second pitched roof board, the below of butt joint piece is equipped with leak protection groove, the top of the cell wall of leak protection water groove both sides can with the bottom surface butt joint of first pitched roof board and second pitched roof board. Further, the locking structure is a rivet structure, and the rivet structure passes through the butt joint piece, the first pitched roof plate and the second pitched roof plate. Further, the top of the butt joint piece is provided with an arc concave surface, and the bottom of the butt joint piece is provided with an arc convex surface. Furthermore, a positioning groove is arranged in the leakage-proof drainage groove, a positioning inserting plate is arranged on the bottom surface of the butt joint piece, and the positioning inserting plate can be matched with the positioning groove. Furthermore, the outer walls at two sides of the leakage-proof drainage groove are provided with a water isolation groove, the bottom surfaces of the first pitched roof plate and the second pitched roof plate are provided with sealing gaskets, and two sides of each sealing gasket can be abutted to the top surfaces of the water isolation grooves. Further, the sealing gasket is a T-shaped rubber piece, and the middle protruding piece of the T-shaped rubber piece can be inserted into the water separation groove. Further, alumina dry particles are filled in the water separation tank. Further, a drain hole is arranged on the wall of the water separation tank. Compared with the prior art, the utility model has the following beneficial effects: The crossed roof anti-leakage structure is provided with multiple seals, a U-shaped rubber part, a locking structure and a T-shaped sealing gasket to block a water seepage path, a leakage-proof drainage groove is arranged to conduct active drainage and conduct flow guidance in cooperation with the water separation groove to avoid water accumulation, and a rubber pad structure and a metal structure are arranged to conduct composite design, so that the structure is high in durability and suitable for expansion with heat and contraction with cold.
