Abstract
The utility model discloses a cold stamping right-angle fastening piece for a steel pipe scaffold. The cold stamping right-angle fastening piece for the steel pipe scaffold comprises a cross-shaped right-angle fastening seat formed in a stamping mode. One end in the transverse direction of the front side of the right-angle fastening seat is connected with a first fastening cover through a pin shaft, and the other end in the transverse direction of the front side of the right-angle fastening seat is connected with a slipknot bolt. A notch matched with the slipknot bolt is formed in the first fastening cover. One end in the longitudinal direction of the back side of the right-angle fastening seat is connected with a second fastening cover through a pin shaft, and the other end in the longitudinal direction of the back side of the right-angle fastening seat is connected with a slipknot bolt. A notch matched with the slipknot bolt is formed in the second fastening cover. Due to the fact that a steel pipe is supported by ladder-shaped block supporting points, and tooth-shaped salient points are evenly distributed on the two fastening covers along an arc surface of the steel pipe, so that the intensity of the fastening pieces and intensity of antiskid displacement are improved by more than 50%, and the problems that an original cold stamping fastening piece is bad in intensity and antiskid performance and the like are solved.
Description
Technical field
The utility model relates to a kind of steel pipe scaffold cold stamping right-angle coupler, belongs to civil engineering work equipment technology field.
Background technology
At present, a large amount of uses is the cast iron fastener in the domestic engineering construction, good rigidly most ofly can satisfy instructions for use, but this fastener is owing to reasons such as material, techniques, there are the problems such as sand holes, pore are arranged in the fastener, cause the toughness of cast iron button fastener little, the coarse heaviness of external form, cast iron fastener high-altitude is not portable, and mounting or dismounting efficient is low, and labour intensity is high; The damage of very easily getting rusty, fastener often extremely can't be dismantled because becoming rusty, and causes the proportion of goods damageds of using in every batch of engineering up to 10%, and maintenance rate increases construction cost greatly up to 15%.And the cross junction of existing cast iron fastener is to connect by bayonet lock, this class formation also comes with some shortcomings, and especially antiskid, torque resistant poor rigidity are easily broken, happened suddenly and cut the poor-performing of lotus, therefore the accident that causes scaffold to collapse because of the fastener fracture occurs in construction repeatedly.
The utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, proposes a kind of steel pipe scaffold cold stamping right-angle coupler, by the improvement to structure, greatly improved stability and safety that scaffold is built.
In order to solve above technical problem, the utility model provides a kind of steel pipe scaffold cold stamping right-angle coupler, comprise stamping forming cross right angle Button Block, a transversely end in Button Block front, described right angle connects the first buckle closure through bearing pin, the other end connects the slip-knot bolt, and described the first buckle closure is provided with the gap with described slip-knot bolt coupling; Vertical upper end at the Button Block back side, described right angle connects the second buckle closure through bearing pin, and the other end connects the slip-knot bolt, and described the second buckle closure is provided with the gap with described slip-knot bolt coupling.
The utility model further limits technical scheme: aforesaid steel pipe scaffold cold stamping right-angle coupler, formation has the arc that matches with circle of steel tube between described the first buckle closure and the second buckle closure and the described right angle Button Block, is provided with double wedge in described cambered surface.
Aforesaid steel pipe scaffold cold stamping fastener, the double wedge on the described cambered surface are provided with eight altogether.
Aforesaid steel pipe scaffold cold stamping fastener also is provided with thrust surface at the opening position of described the first buckle closure and the second buckle closure, prevents the slippage of slip-knot bolt.
Further, aforesaid steel pipe scaffold cold stamping fastener, described cross right angle Button Block is equipped with trapezoidal back-up block with the back side of the end that described the first buckle closure links to each other with the second buckle closure, in order to supporting steel pipe.
The beneficial effects of the utility model are: the utility model is owing to having adopted trapezoid block strong point supporting steel pipe and two buckle closures along the uniform dentation salient point of steel pipe arc surface, fastener is improved more than 50% in intensity, antiskid displacement intensity, overcome original cold stamping fastener in the problem such as intensity, antiskid is poor.

The specific embodiment
A kind of steel pipe scaffold cold stamping right-angle coupler that the present embodiment provides, structure as depicted in figs. 1 and 2, comprise stamping forming cross right angle Button Block 1, a transversely end in right angle Button Block 1 front connects the first buckle closure 4 through bearing pin 8, the other end connects slip-knot bolt 11, the first buckle closures 4 and is provided with the gap that mates with the slip-knot bolt; Vertical upper end at right angle Button Block 1 back side connects the second buckle closure 3 through bearing pin, the other end connects slip-knot bolt 12, the second buckle closure 3 is provided with the gap with slip-knot bolt coupling, opening position at the first buckle closure 4 and the second buckle closure 3 also is provided with thrust surface, form between the first buckle closure 4 and the second buckle closure 3 and the right angle mouth seat and have the arc that matches with circle of steel tube, be provided with double wedge 17 in cambered surface, the double wedge on the cambered surface is provided with eight altogether; Cross right angle Button Block is equipped with trapezoidal back-up block 5,6,13,14 with the back side of the end that the first buckle closure 3 links to each other with the second buckle closure 4.
The present embodiment is comprised of cold stamping shaped cross right angle Button Block and the first buckle closure and the second buckle closure, right angle Button Block dorsad one cold punching becomes two axial lines to intersect and is orthogonal, respectively there are four support terraced pieces 5,6,13,14 Button Block four ends dorsad in right angle, be provided with dentation salient point 17 in the first buckle closure 4 and the second buckle closure 3, Button Block 1 a horizontal and vertical end separately in right angle is flexibly connected through pin 8, the 7 and first buckle closure 4 and the second buckle closure 3, makes about the first buckle closure and the second buckle closure energy to freely swing.The horizontal and vertical other end of right angle Button Block 1 through pin 9,10 and slip- knot bolt 11,12 be flexibly connected, freely swing about slip- knot bolt 11,12 energy.During use, steel pipe 15,16 is put into respectively the horizontal and vertical mounting groove of right angle Button Block 1, close with the first buckle closure 4 and the second buckle closure 3 and the slip- knot bolt 11,12 of dentation salient point 17, screw the nut on the bolt, make on right angle Button Block 1 two end faces dorsad four trapezoid blocks 5,6,13,14 separately support steel pipe 15,16, the pulling force that produces separately in 90 ° of directions, by right angle Button Block 1 and the first buckle closure 4 and the second buckle closure 3 engagement forces with dentation salient point 17, the displacement that has effectively overcome steel pipe with reverse.
