Strong-strength machine-made handmade sandwich board

Abstract

The invention discloses a strong-strength machine-made handmade sandwich board, which comprises a sandwich core material and panels covering the surfaces of the two sides of the sandwich core material, wherein side plates with U-shaped sections are arranged at the left and right side ends of the sandwich core material respectively; the longitudinal edge ends of the two panels extend and are folded to be connected with the side plates in a rolling way to form male and female tongues and grooves at the left and right ends of the sandwich core material; reinforced connecting bands are also arranged at the upper and lower side ends of the sandwich core material; groove structures or tenon structures are formed on the middle parts of the reinforced connecting bands, are connected with the sandwich core material in an embedding way, and are closely connected with the panels to strengthen the transverse strength of the board. According to the color steel sandwich board, transversely adjacent color steel sandwich boards are spliced and matched by virtue of the male and female tongues and grooves at the left and right ends of the sandwich core materials; the reinforced connecting bands are also arranged at the upper and lower ends of the sandwich core material, the strength of the board is strengthened by the reinforced connecting bands, and meanwhile, the groove structures or the tenon structures of the reinforced connecting bands can be used for connecting longitudinally adjacent color steel sandwich boards in a matched way to ensure convenient and rapid assembly positioning.

Description

technical field [0001] The invention relates to the technical field of building panels, in particular to a color steel sandwich panel. Background technique [0002] The color steel sandwich panel product is composed of two layers of formed metal panels and the inner core. The color steel sandwich panel not only has the high mechanical strength of the steel material, the performance of easy forming, but also has the good decoration and corrosion resistance of the coating material. . At present, the manual color steel sandwich panels on the market are cumbersome in production process, relying on manual operation, high cost, complicated connection between panels, and the sandwich core material and the card groove frame on the surrounding end faces are not connected as a whole, resulting in the local Insufficient strength; and although the machine-made color steel sandwich panels on the market have the advantages of simple manufacturing process and low cost, and the splicing ...

AI Technical Summary

Problems solved by technology

At present, the manual color steel sandwich panels on the market are cumbersome in production process, relying on manual operation, high cost, complicated connection between panels, and the sandwich core material and the card groove frame on the surrounding end faces are not connected as a whole, resulting in the local Insufficient strength; and although the machine-made color steel sandwich panels on the market have the advantages of simple manufacturing process and low cost, and the splicing of male and female grooves between the longitudinal outer sides of the panels, which has the advantages of simple fastening, etc., there is no such thing as the lateral outer sides. The frame is closed, the core material is exposed, the compressive strength of the lateral end face is insufficient, it is easy to enter and absorb water, the vertical splicing is inconvenient, unsightly, and does not meet the requirements for purification, etc.
