Abstract
The utility model discloses a cross-shaped fastener of a steel pipe scaffold, which comprises an upper half fastener, a lower half fastener, a slipknot bolt, a nut and a gasket. The upper half fastener is connected with the lower half fastener through a rivet and the slipknot bolt to form sub-fasteners, and the middles of lower half fasteners of the two sub-fasteners coincide. Two ends of the lower surfaces of the lower half fasteners of the sub-fasteners in the length direction are provided with stamping protrusions for enhancing fixing effect to a steel pipe. The tail end of thrust surface of the upper half fastener is provided with a protrusion for preventing the nut on the slipknot bolt and the gasket from sliding out of an opening. The cross-shaped fastener of the steel pipe scaffold has strong anti-sliding capability and is a rotating fastener of the steel pipe scaffold which can still work stably and reliably under the action of multi-directional variable loads.
Description
Technical field
The utility model relates to a kind of fastener, especially relates to a kind of steel pipe scaffold rotary buckle.
Background technology
The appearance of steel tube scaffold clasp makes that the steel pipe scaffold mounting or dismounting are convenient, sets up more flexible; Because steel pipe length is easy to adjustment, it is easy that fastener connects, thereby the building and the structure that can adapt to various planes, facade are used scaffold; Both economical, accelerated the building operations progress to a certain extent, wherein; Rotary buckle can connect arbitrarily angled two steel pipes, has more flexibility; Yet existing rotary buckle is appointed the radial constraint poor effect that so exists steel pipe; Under flat numerous non-single load effects such as bending, turn round, the nut on the slip-knot bolt is prone to skid off shortcomings such as gap.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of anti-slide performance strong, the still reliable and stable steel pipe scaffold rotary buckle of work under the effect of multidirectional varying load.
The technical scheme of the utility model is: a kind of steel pipe scaffold cruciform fastening for falsework comprises first button, second button; The slip-knot bolt, nut, packing ring; First button is connected with the slip-knot bolt through rivet with second button, the composition fastener, and second of two fens fasteners partially overlaps between smashing.It is the stamped bumps that strengthens the fixed effect of steel pipe that second that divides fastener detains on the length surface direction that two ends are provided with.The thrust surface end of first button is provided with the convexity that the nuts and washers that prevents on the slip-knot bolt skids off gap.
Two ends are provided with stamped bumps on the length surface direction because second of branch fastener detained; Under the synergy of first button; Make the utility model be greatly enhanced to the fixed effect of steel pipe; Effectively prevented the play of steel pipe, and then made the whole anti-slide performance of scaffold get very big raising; Because the convexity that is positioned at the gap limit that first button thrust surface end is provided with makes that the nuts and washers on the slip-knot bolt is unlikely under the effect of multidirectional varying load, to skid off gap, the work stability of the utility model is guaranteed.
Description of drawings:
Fig. 1 is the utility model embodiment overall structure sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
With reference to Fig. 1, present embodiment comprises first button 1, second button 2; Slip-knot bolt 4; Nut 5, packing ring 7, first button 1 are detained 2 with second and are connected with slip-knot bolt 4 through rivet; Composition fastener, second of two fens fasteners are detained 2 mid portions and are overlapped (second of promptly two minutes fasteners detained 2 and belonged to integrally-built each symmetric part respectively); It is the stamped bumps 3 that strengthens the fixed effect of steel pipe that second of said minute fastener detains on the 2 soffit length directions that two ends are provided with; First button thrust surface end of 1 is provided with the convexity 6 that the nut 5 that prevents on the slip-knot bolt 4 and packing ring 7 skid off gap.
Two ends are provided with stamped bumps 3 on the 2 soffit length directions because second of said minute fastener detained; Under the synergy of first button 1; Make the utility model be greatly enhanced to the fixed effect of steel pipe; Effectively prevented the play of steel pipe, and then made the whole anti-slide performance of scaffold get very big raising; Because first detains the convexity that is positioned at the gap limit 6 that 1 thrust surface end is provided with, make that the nut 5 on the slip-knot bolt 4 is unlikely under the effect of multidirectional varying load, to skid off gap with packing ring 7, the work stability of the utility model is guaranteed.
