Description
Technical field
The utility model relates to screen technical field, specifically a kind of screen carrier round tube and round tube interconnection
Fastener.
Background technique
Movie screen in usual movie theatre needs to carry out taut hang by screen carrier and installs, and meets motion picture projection in taut lacing screen
While demand, also to meet certain structural strength, structural stability and anti-overturning, with meet movie theatre construction requirements and
The requirement of concerned countries standard.
Currently, movie theatre is mainly built by pipe fitting with screen carrier, the method for site welding is generallyd use between component
Or it is fixed using building scaffold fastener.
Since existing screen carrier mostly uses greatly the fixed form of site welding to carry out building assembling, live electricity consumption is needed, and
Open fire is generated in welding, easily leads to the safety accidents such as fire, while after welding is built, screen carrier size is fixed, non-adjustable
It is whole, therefore be difficult to modify when deviation occurs in installation, and site welding assembling needs construction personnel to have corresponding construction quality,
Can guarantee the welding quality between component not influences the stabilized soil pavement of frame body.The frame body weld job working time is longer, people
Member's large labor intensity, especially also needs construction personnel to carry out high altitude operation, to a certain extent when building large-scale screen carrier
The difficulty of construction is increased, so that set-up time and installation cost, risk all greatly improve；And building scaffold fastener is usual
For steel casting, volume, weight are larger, and carrying similar fastener will increase the labor burden for the operating personnel that ascends a height.
Summary of the invention
In order to avoid with solve above-mentioned technical problem, the utility model proposes a kind of screen carrier round tubes to intersect with round tube
The fastener of connection.
Technical problem to be solved in the utility model is realized using following technical scheme:
A kind of fastener of screen carrier round tube and round tube interconnection, including two U-shaped card parts, described two U type fasteners

Preferably, the nut is directly anchored on U-shaped card part.
The utility model passes through the U-shaped card part and semicircle designing and developing different connection types, adapt to different pipe fitting specifications
Liner is produced using the assembling that the techniques such as punching press, welding complete U-shaped card part, semicircle liner and whole fastener, instead of conventional silver
Curtain frame welds the Installation Modes built, and electric welding is employed when screen carrier being avoided to build, and generates open fire and causes security risk, keeps away simultaneously
Exempt from building scaffold casting fastener volume, the biggish defect of weight, the operating personnel that conveniently ascends a height carries.
While meeting screen carrier Structural strength calls, traditional screen is replaced using simple light screen carrier fastener
Frame welding builds technique and borrows building scaffold fastener phenomenon.
The beneficial effects of the utility model are:
1, screen carrier pipe fitting is connected using fastener, so that screen carrier erecting bed is not needed electric welding, without open fire, will not generates
Fire safety evaluating hidden danger；Fastener is suitable for different pipe fitting specifications, adapts to different setting angles with adjustable or fixed connection type
It is required that while fastener use bolt fastening, installation effectiveness and the reduction of screen carrier can be greatly promoted with the use of electric wrench
The labor intensity and skill requirement degree of installation personnel.
2, the tensile strength of fastener is in 30000N~35000N or so, bending strength in 700N/m~800N/m or so,
Intensity is high, and stability is good, meets screen carrier structural strength and stability requirement, completely alternative to weld the side for building screen carrier
Method.
3, fastener installation can carry out dismounting adjustment in time depending on the site environment, to meet the control of screen carrier installation accuracy
It is required that and be suitable for showing the interim adjustment variation of parameter, it may be convenient to carry out the adjustment of screen carrier specification.
4, fastener structures are simply light, are conducive to screen carrier site operation personnel and carry installation.
