Inlaid frame manufacturing method for producing environment-friendly flame-retardant acoustic board

Abstract

The invention discloses an inlaid frame manufacturing method for producing an environment-friendly flame-retardant acoustic board. The technical scheme includes that counter bores are processed on the upper planes of short steel pipes, the short steel pipes are welded into a rectangular frame through punching steel screens, and reinforcing ribs are welded in the rectangular frame through deformed steel bars by utilizing diagonal lines at 1 / 2 of heights of the short steel pipes as joints and form an inlaid frame together. By adopting the inlaid frame to produce the environment-friendly flame-retardant acoustic board, the environment-friendly flame-retardant acoustic board and the inlaid frame are integrated, so that the integral strength, counter bending capacity and practical using effect of the environment-friendly flame-retardant acoustic board are improved. On a construction site, the environment-friendly flame-retardant acoustic board can be directly mounted on the wall of a building, so time and labor are saved, the environment-friendly flame-retardant acoustic board is protected from being broken and falling off the wall of the building. Besides, the inlaid frame manufacturing method is applicable to manufacturing various environment-friendly flame-retardant acoustic boards for facilities such as expressways, subways and public places.

Description

technical field [0001] The invention relates to a frame, in particular to a manufacturing method of a built-in frame for producing an environment-friendly flame-retardant sound-absorbing panel. Background technique [0002] With the increasing awareness of global safety and environmental protection, people have higher and higher requirements for fire safety and flame retardancy of products. Halogen-free, low-smoke, low-toxic environment-friendly flame retardants have become the goal pursued by people. [0003] Urban noise seriously affects the normal life and personal health of urban residents. Urban noise mainly refers to traffic noise, factory noise, construction noise and social life noise. It has become one of the conspicuous urban environmental pollution problems. [0004] Usually, sound-absorbing materials are used to produce some sound-absorbing panels, sound-insulating walls, sound-absorbing nets and mufflers to control noise pollution, and some sound-absorbing mate...

AI Technical Summary

Problems solved by technology

[0005] At present, the texture of the foamed sound-absorbing panels sold on the market is relatively brittle, and the overall strength, bending resistance and use effect of the sound-absorbing panels are not ideal; in the process of installing the sound-absorbing panels on the wall of the building, the sound-absorbing panels need to drill 4 on-site The above bolt holes are not only labor-intensive and time-consuming, but also increase the difficulty of construction, and it is easy to damage or shatter the sound-absorbing panel when drilling. When the sound-absorbing panel is installed on the wall of the building, due to the effect of gravity, it will cause The sound-absorbing panels after drilling are broken and peeled off from the building wall
