A super thick sgp laminated glass

Abstract

The invention belongs to the technical field of glass, and specifically relates to an ultra-thick SGP laminated glass; comprising a glass body, a film layer is arranged inside the glass body, and a plurality of cylinders are arranged inside the film layer, and inside the cylinder A piston rod is provided, and one end of the piston rod located outside the cylinder body is fixedly connected with the glass main body. Both sides of the cylinder body are connected with a connecting pipe, and one end of the connecting pipe is connected with a butterfly pipe. The four ends are provided with matching first arc rods, and the inside of the film layer is provided with a card slot, and the card slot includes an arc segment and a change segment, and the first arc rod matches the arc segment ; The present invention uses the butterfly tube, the first arc-shaped rod and the second arc-shaped rod. When the external force is small, the first arc-shaped rod moves in the butterfly tube, and the first arc-shaped rod supports the glass body. When the external force is large, the second arc-shaped rod plays a role in tensioning the stressed two sides of the glass body.

Description

technical field [0001] The invention belongs to the technical field of glass, in particular to an ultra-thick SGP laminated glass. Background technique [0002] SGP laminated glass is produced by more than two pieces of glass and SGP film through a certain production process. As a very reliable safety glass, SGP laminated glass is widely used in the construction field, especially in some important explosion-proof places. Among them, the glass substrate of ultra-thick SGP laminated glass usually refers to tempered or semi-tempered glass with a thickness greater than 11mm. The specification of SGP film can be selected according to the production requirements of the process. After the laminated glass is synthesized, the total thickness is greater than 22.52mm. Ultra-thick SGP laminated glass has higher safety and energy-saving characteristics than ordinary laminated glass (safety can be reflected in the falling ball impact test and shot bag impact performance test).

AI Technical Summary

Problems solved by technology

[0003] The laminated glass in the prior art, because the middle part is a layer of 1.52mm film, when it is subjected to external force, the middle part will be slightly deformed, and it will be used for a long time, resulting in loosening of the glass and the film. When the external force is greater, it is used for glass. The effect of stress causes excessive deformation in the middle of the glass, and the stress on both sides causes the glass to break. In view of this, the present invention provides an ultra-thick SGP laminated glass, which can support it when the external force is small. When the external force is large, it acts as a tension on both sides of the force
