Abstract
The utility model discloses an anti-skid suspension girder fastener which comprises a suspension frame provided with a 'C' shape clamping groove structure, an ejector rod is arranged at the upper end of the suspension frame through a threaded hole in a threaded combination mode, a notch is arranged in the middle of the lower end of the suspension frame in a sunken mode, an arc-shaped fastening piece is further arranged at the lower end of the suspension frame, one end of the arc-shaped fastening piece is connected with one side of the lower end of the suspension frame in a hinged mode, the other end of the arc-shaped fastening piece is provided with a fork-shaped opening and is tightly fixed on the other side of the lower end of the suspension frame through a slipknot bolt, the arc-shaped fastening piece and the notch at the lower end of the suspension frame form a fastening portion similar to a round shape, round cake shape protrusions are arranged on the inner wall of the arc-shaped fastening piece, and anti-skid lines are arranged on a contact surface of the clamping groove structure of the suspension frame. The anti-skid suspension girder fastener is simple in structure, convenient to install and use, and effectively improves friction force of a frame pipe in the fastening portion of the suspension girder fastener and friction force between the suspension frame and a steel structure, skid of the frame pipe after the frame pipe is used in long time in the fastening portion of the suspension girder fastener is avoided, the suspension girder fastener is prevented from skidding out of the steel structure, and using safety of scaffolding is effectively guaranteed.
Description
Technical field
The utility model relates to a kind of fastener, is specially a kind of anti-slip overarm fastener.
Background technology
At the realm of building construction, when setting up the overarm suspension bracket on the steel work or setting up the support of tall and big scaffold, the frame pipe need to be fastened on the steel work, the method in past is to adopt the iron wire binding, yet this method protective is relatively poor, and iron wire is fragile, can produce in the scaffold use procedure and rock, make between frame pipe and the steel work and produce the gap, use for a long time dangerous.In order to improve safety, present employed method is to adopt right-angle coupler to embrace beam to reinforce, and four frame pipe rings are embraced and fastened steel work, and safety is higher, and the shortcoming of this method is that cost is high, and fitting operation is wasted time and energy, and efficient is low, delays construction speed.Therefore the overarm fasteners that adopt replace right-angle coupler more at present, because it is time saving and energy saving that overarm fastener fitting operation is compared right-angle coupler, cost is low, and efficient is higher, however the anti-slip poor-performing of existing overarm fastener, easily cause the frame pipe in the buckle portion of overarm fastener, to slide after long-time the use, and the slippage from the steel work of overarm fastener, if untimely reinforcing easily causes scaffold to rock, therefore stability decreases exists potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of anti-slip overarm fastener, to solve traditional anti-slip poor-performing of overarm fastener in the prior art, the long-time after-frame pipe that uses easily slides in the buckle portion of overarm fastener, and overarm fastener slippage from the steel work, if untimely reinforcing, therefore easily cause scaffold to rock, there is the problem of potential safety hazard in stability decreases.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of anti-slip overarm fastener, it is characterized in that: include the suspension with " C " type notch, described suspension upper end is screwed with push rod by screwed hole, described suspension lower end medial recess has gap, described suspension lower end also is provided with the arc cramp, one end of described arc cramp is hinged on suspension lower end one side, the other end of described arc cramp is provided with the fork-shaped opening and passes through the slip-knot bolton at the opposite side of suspension lower end, the gap of described arc cramp and suspension lower end forms the buckle portion of sub-circular, described arc cramp inwall is provided with the patty projection, and the contact surface of described suspension notch is provided with anti-slip veins.
Described a kind of anti-slip overarm fastener is characterized in that: described suspension is the trapezoidal shape that the upper end is longer than in the lower end.
Described a kind of anti-slip overarm fastener is characterized in that: with the screw thread that cooperates with screwed hole, described push rod rod end is provided with the hemispherical top on the described push rod.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to install, effectively promoted efficiency of construction, employing arranges patty projection and the design of anti-slip veins is set at the contact surface of suspension notch at arc cramp inwall, effectively promoted the frame pipe in overarm fastener buckle portion frictional force and frictional force between suspension and the steel work, prevent from using for a long time the after-frame pipe in the buckle portion of overarm fastener, to slide and the slippage from the steel work of overarm fastener, effectively ensured the safety that scaffold uses.
