Abstract
The utility model discloses a reinforced type 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, reinforced ribs are arrange on the outer 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 reinforced type anti-skid suspension girder fastener is simple in structure, convenient to install and use, effectively improves the anti-skid performance and mechanical strength of the suspension girder fastener, further improves stability of the suspension girder fastener, and effectively guarantees the using safety of scaffolding.
Description
Technical field
The utility model relates to a kind of fastener, is specially a kind of reinforced 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, efficient is higher, yet the anti-slip poor-performing of existing overarm fastener causes the frame pipe to slide in the buckle portion of overarm fastener after long-time the use easily, and overarm fastener slippage from the steel work, if untimely reinforcing causes scaffold to rock stability decreases easily; And the mechanical performance of overarm fastener is also relatively poor, occurs easily the phenomenons such as cramp distortion, fracture of overarm fastener after long-time the use, affects the stability of scaffold, has potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of reinforced anti-slip overarm fastener, relatively poor with the anti-slip performance and the mechanical performance that solve overarm fastener traditional in the prior art, occur easily loosening after long-time the use and the phenomenons such as distortion, fracture, there is the problem of potential safety hazard in cause the hanging oneself from a beam stability decreases of fastener.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of reinforced anti-slip overarm fastener, it is characterized in that: include the suspension with " C " type notch, described suspension upper end has screwed togather 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, described arc cramp outer wall is provided with reinforcing rib, and the contact surface of described suspension notch is provided with anti-slip veins.
Described a kind of reinforced 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 reinforced anti-slip overarm fastener, it 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; Employing is provided with the design of reinforcing rib at arc cramp outer wall, effectively promoted the mechanical strength of overarm fastener, use for a long time the phenomenons such as rear cramp of hanging oneself from a beam fastener also is difficult for deforming, fracture, promoted the stability of overarm fastener, effectively ensured the safety of scaffold use.
