Caulking construction structure for surface layer dividing joints of building roof
2013
The utility model discloses a caulking construction structure for surface layer dividing joints of a building roof. The caulking construction structure comprises elastic bars and sealing layers, wherein the roof dividing joints are tightly filled with the elastic bars, the dividing joints of the surface layer are arranged on a rigid protection layer of the building roof, the sealing layers are distributed on the upper portions of the elastic bars, the elastic bars and the sealing layers are distributed from front to back in the extending direction of the roof dividing joints, the width of each elastic bar is not smaller than d1 which is equal to 1.2*d2, d2 is the width of a roof dividing joint, and the upper surface of each sealing layer is in a concave-arc shape. The rigid protection layer of the building roof can be a cement mortar protection layer, or a fine aggregate concrete protection layer, or a third rigid protection layer with the upper portion paved with face bricks. The caulking construction structure is reasonable in structure design, convenient to construct, high in work efficiency, and attractive in appearance of formed dividing joint after construction, construction quality can be easily guaranteed, the cracking phenomenon can not easily occur, and the problems that construction operation is arbitrary and irregular, the thicknesses of caulked joints are not uniform, rubber face quality is difficult to control, rubber faces easily crack, and the appearance is not attractive in existing caulking construction of dividing joints are solved.
