Abstract
The invention discloses a scaffold butt joint fastener which is high in working efficiency, safe and reliable. The inner end of an upper fastening plate and the inner end of a lower fastening plate are matched in a hinged mode, the outer end of the upper fastening plate and the outer end of the lower fastening plate are movably matched, and insertion lugs at the outer end of the upper fastening plate and insertion lugs at the outer end of the lower fastening plate are matched in a staggered and mutually embedded mode. An insertion plate is matched with the insertion lugs in an inserting mode. Insertion holes are formed in the centers of the insertion lugs. Annular partition plates are arranged on the inner wall of the upper fastening plate and the inner wall of the lower fastening plate and located between the upper fastening plate and the lower fastening plate. Due to the fact that the insertion plate is matched with the insertion lugs in the inserting mode, installation efficiency is greatly improved. Due to the fact that the annular partition plates are arranged on the inner wall of the upper fastening plate and the inner wall of the lower fastening plate, pipes are not prone to disengaging, safety and reliability of a scaffold set up is high, and working efficiency is also greatly improved.
Description
Technical field
The present invention relates to a kind of fastener of scaffold.
Background technology
Scaffolding erecting is the indispensable program in building operations.At present, during scaffold connects, needing to use various connection fasteners, no matter use which kind of fastener, is all that finally to adopt bolt to carry out fastening substantially.During operation, workman is for a long time in high altitude environment operation, and a handgrip, on pipe support, keeps one's balance, the hand-tight fixing bolt of another, and fastening bolt is consuming time longer, the inconvenience that operates, inconvenience especially operates when running into bolt corrosion and damaging.When docking two pipe, often can cause in operation a pipe to put in fastener longer, another pipe stretches into situation shorter in fastener, the danger that easily causes pipe fitting to skid off.The particular location of interface that cannot see two pipes due to operative employee in fastener, can only by experience and repeatedly verification solve, for the new hand who lacks experience be in the operator of frazzle, operating efficiency can decline greatly and construction quality is difficult to be guaranteed, and scaffold exists certain potential safety hazard.
Summary of the invention
The object of this invention is to provide the high and safe and reliable scaffold of a kind of operating efficiency to clasp.
Technical scheme of the present invention is: comprise buckle and lower pinch plate, upper buckle and lower pinch plate are circular arc, the hinged cooperation in the inner of upper buckle and the inner of lower pinch plate, the outer end of upper buckle and the outer end of lower pinch plate are movable to be coordinated, the outer end of described upper buckle and the outer end of lower pinch plate are equipped with slotting ear, Cha Er center is provided with jack, slotting ear on upper buckle outer end and the slotting ear on lower pinch plate outer end are all vertically dentation and distribute, the staggered phase scarf of slotting ear on upper buckle outer end and the slotting ear on lower pinch plate outer end closes, and plate is pegged graft and coordinated with slotting ear.
On described upper buckle inwall and lower pinch plate inwall, be equipped with annular baffle, this annular baffle is positioned at the centre of buckle and lower pinch plate.
The jack at described Cha Er center is wedge shape vertically, the profile of described plate be wedge structure corresponding to jack.
Owing to adopting plate to peg graft and coordinate the jack at ，Cha Er center to be vertically wedge shape with slotting ear in the present invention, the profile of plate be wedge structure corresponding to jack, therefore, does not need to use bolt to carry out fastening, and installation effectiveness improves greatly.On upper buckle inwall and lower pinch plate inwall, be equipped with annular baffle, this annular baffle is positioned at the centre of buckle and lower pinch plate, during installation, tube end pushes up to the end in opposite directions, inconsistent with annular baffle and till can not move time, now the end of two pipes is just in time positioned at the centre of upper and lower buckle, therefore again, pipe is difficult for deviating from, and the higher and operating efficiency of the security reliability of the scaffold of building also improves greatly.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of structure of the present invention.
Fig. 2 is the open configuration schematic diagram of Fig. 1.
Fig. 3 is the STRUCTURE DECOMPOSITION schematic diagram of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail, but does not form any limitation of the invention.Shown in Fig. 1, Fig. 2 and Fig. 3, the present invention includes buckle 1 and lower pinch plate 2, upper buckle 1 and lower pinch plate 2 are circular arc, and the inner of the inner of upper buckle 1 and lower pinch plate 2 is by the hinged cooperation of hinge 4.The outer end of the outer end of described upper buckle 1 and lower pinch plate 2 is equipped with slotting ear, Cha Er center is provided with jack, slotting ear on upper buckle 1 outer end and the slotting ear on lower pinch plate 2 outer ends are all vertically dentation and distribute, the staggered phase scarf of slotting ear on upper buckle 1 outer end and the slotting ear on lower pinch plate 2 outer ends closes, and plate 3 is pegged graft and coordinated with slotting ear.On described upper buckle 1 inwall and lower pinch plate 2 inwalls, be equipped with annular baffle 5, this annular baffle 5 is positioned at the centre of buckle 1 and lower pinch plate 2.The jack at described Cha Er center is wedge shape vertically, the profile of described plate 3 be wedge structure corresponding to jack.
During use, first upper buckle 1 and lower pinch plate 2 are connected in series by hinge 4, buckle 1 and lower pinch plate 2 can be rotated freely along hinge 4.During installation, the end of two pipes is inserted in lower pinch plate 2, until then annular baffle 5 places share upper buckle 1 with lower pinch plate 2, with plate 3, insert in the jack in upper buckle 1 and lower pinch plate 2, and knock in and be seated with hammer.During dismounting, plate 3 other ends that hit with a hammer, take out plate 3.
