Arc-shaped prefabricated bleacher plate mold and manufacturing method thereof

Abstract

The invention provides an arc-shaped prefabricated bleacher plate mold and a manufacturing method thereof. The arc-shaped prefabricated bleacher plate mold comprises a pedestal, wherein a left side mold and a right side mold of which the cross sections are arc-shaped are arranged on the upper surface of the pedestal; a bottom mold is arranged between the left side mold and the right side mold, isinverted U-shaped, and is provided with a top plate, a left side plate and a right side plate; two side edges of the top plate as well as the cross sections of the left side plate and the right side plate are also arc-shaped; the radians of the two side edges of the top plate as well as the cross sections of the left side plate and the right side plate are the same as those of the left side mold and the right side mold; an arc-shaped left bottom mold is arranged between the left side plate and the bottom of the left side mold; an arc-shaped right bottom mold is arranged between the right sideplate and the bottom of the right side mold; the radians of the left bottom mold and the right bottom mold are the same as those of the left side mold and the right side mold; a bottom mold bracket isarranged below the top plate; a left stiffening plate is arranged between the bottom mold bracket and the bottom of the left side plate; a right stiffening plate is arranged between the bottom mold bracket and the bottom of the right side plate; end molds are arranged at two ends of the bottom mold bracket; and a casting space is formed among the end molds, the left side mold, the right side mold, the bottom mold, a suspended mold, the left bottom mold and the right bottom mold in an encircling manner.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to an arc-shaped prefabricated grandstand board mold and a manufacturing method thereof. Background technique [0002] Prefabricated prefabricated stands are now more and more widely used in sports venues. The mold design and manufacturing process of broken-line and straight-line stands are relatively mature. According to the cross-sectional forms of the stands, they are mainly U-shaped, L-shaped, flat-shaped, T-shaped, etc. . Straight lines and broken lines are easy to produce and construct because of their straight lines and easy control of size, but they increase the difficulty of special design and installation when encountering arcs in the venue, and the space utilization is not reasonable enough. With the development of technology and the pursuit of aesthetics, the demand and voice of arc-shaped grandstand boards are gradually emerging. Curved-shaped grandsta...

AI Technical Summary

Problems solved by technology

For the arc-shaped stand board, in the prefabricated mold, the main difficulty lies in the forming of the arc-shaped panel, the fixing of the arc-shaped supporting rib and the channel steel. If the structure of these parts is unreasonable, the dimensional accuracy of the casting cannot be guaranteed. Ensure the rigidity and stability of the mold, which will also reduce the accuracy of the casting, which is a technical problem that the industry has not yet overcome
