Detailed Description
In order to make the present invention better understood by those skilled in the art, the present invention will be further clearly and completely described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
As shown in fig. 1 to 3, the shaping device for the prefabricated roof vent hole foundation comprises a steel die 1 and a pedestal; the integral shape of the steel mould 1 is quadrangular frustum pyramid, baffles are arranged on four side surfaces and the top surface of the steel mould, the bottom surface is open, a reserved opening 2 is formed in the center of the baffle on the top surface, and the four side baffles are inwards concave arc baffles; an embedded pipeline 3 is arranged in the steel die 1 along the axis of the steel die, the top of the embedded pipeline 3 is in butt joint and fixed connection with a reserved opening 2 in the top baffle, connecting ribs 4 are respectively fixed on two sides of the bottom of the embedded pipeline 3, and the other end of each connecting rib 4 is fixedly connected with the bottom edge of the steel die 1; the pedestal is provided with an installation groove matched with the shape of the top of the steel die 1; the top of the steel die 1 faces downwards and is arranged in a mounting groove on a pedestal.
In the device, the steel die 1 is formed by butt joint and assembly of two single dies 5 with the same structure along the central line thereof, a plurality of sets of connecting pieces are uniformly distributed along the butt joints of the two sides and the top baffle, each set of connecting piece comprises two connecting buckles 6 fixed on the two sides of the butt joint, and a fastening bolt 7 is connected in the two connecting buckles 6. The structure of the single mold 5 is shown in fig. 4, and includes a complete side baffle, two sides of the complete side baffle are respectively provided with a half side baffle, and three connecting buckles 6 are fixed on the plate edges of the two half side baffles from top to bottom; the top of the complete side baffle is a half top baffle, the top baffle is provided with a half reserved opening 2, and the plate edges of the half top baffle are respectively fixed with a connecting buckle 6 at the two sides of the half reserved opening 2; a half of pre-buried pipe 3 is arranged at the butt joint surface of the single mould 5, the top of the half of pre-buried pipe 3 is in butt joint with and fixedly connected with the half of reserved port 2, connecting ribs 4 are respectively fixed on two sides of the bottom of the half of pre-buried pipe 3, and the other end of each connecting rib 4 is fixedly connected with the bottom edge of the half of side baffle; the two single molds 5 are butted to form the complete steel mold 1, and the fastening bolts 7 penetrate through the two corresponding connecting buckles 6 to form the complete steel mold 1.
