Description
Technical field
The utility model relates to screen mounting technique field, specifically a kind of screen carrier ground fixing device.
Background technique
It is installed it is well known that the movie screen in movie theatre needs to carry out taut hang by screen carrier, meets electricity in taut lacing screen
While shadow shows demand, to meet certain structural strength, structural stability and anti-overturning, also to meet the construction of movie theatre
It is required that and concerned countries standard requirement.
Currently, movie theatre is mainly the support screen of screen carrier stand piece with screen carrier, then is built by pipe fitting, between component
It generallys use the method for site welding or is fixed using building scaffold fastener.
Since existing screen frame member uses the fixed form of site welding to carry out building assembling mostly, live use is needed
After electricity, and generate open fire in welding, easily leads to the safety accidents such as fire, while welding is built, screen carrier size, position is consolidated
It is fixed, it cannot be adjusted, therefore be difficult to modify when deviation occurs in installation, and site welding assembling needs construction personnel to have to apply accordingly
Wage matter, just can guarantee the welding quality between component not influences the stabilized soil pavement of frame body, simultaneously because frame body welding is made
The industry working time is longer, and personnel labor intensity is larger.
Generally, common screen carrier footing is directly anchored on ground by expansion bolt, after the installation is completed screen carrier frame body position
Set it is irremovable, if there are installation deviation or other the case where needing mobile screen rack position in scene, it is necessary to discarded original
The fixation position of expansion bolt, again can leave the bolt hole that footing displacement punching is installed again, therefore abandoned to ground need not
The destruction wanted.
