Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-5, a double-sided laminated wallboard door and window opening formwork structure is characterized in that a side formwork 5 made of metal is arranged when a door and window opening is prefabricated, the section of the side formwork 5 is in a shape of a trapezoid 21274, and a rubber strip 6 which is profiled with the side formwork 5 is arranged on the inner side of the side formwork; the internal width of the side die 5 is matched with the thickness of the door and window opening of the prefabricated part; the side forms 5 are clamped at the door and window hole part from inside to outside through the rubber strips 6.
In this embodiment, referring to fig. 1-2, the door/window opening is rectangular, and the side forms 5 include an upper side form 1, a lower side form 4, a left side form 2, and a right side form 3.
In this embodiment, referring to fig. 1-2, the left side die 2 and the right side die 3 are arranged below two sides of the upper side die 1, and form upward supports for two ends of the upper side die 1; and two ends of the lower side die 4 are propped against the inner sides of the left side die 2 and the right side die 3.
In this embodiment, with continued reference to fig. 1-2, the rubber strip inside the upper lip mold 1 is flush with the upper lip mold 1 in length; the rubber strip on the inner side of the lower side die 4 is longer than the lower side die 4, and two ends of the rubber strip slightly extend out of the lower side die 4; the lower ends of the rubber strips on the inner side of the left side die 2 are flush, and the upper ends of the rubber strips slightly extend out of the left side die 2; the lower end of the rubber strip at the inner side of the right side die 3 is flush, and the upper end of the rubber strip slightly extends out of the right side die 3; the protruding portion 601 of the rubber strip is used for sealing and fixing.
