Abstract
The invention provides a slide resisting construction fastening device which comprises two separate fastening members, the small end of the lower fastening member in each separate fastening device is connected with a swing bolt, while the big end is connected with the upper fastening member with an access slit and a thrust surface, the two separate fastening devices are connected through rivet, thus can be rotated at any angle. The advantages of the invention includes increased strength of extension and improved torque resisting stiffness.
Description
Technical field: what the present invention relates to is a kind of building buckle, and particularly a kind of antiskid fastener for building belongs to building machinery part 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, technologies, there is following shortcoming: problems such as sand holes, pore are arranged in the fastener, cause the toughness of cast iron fastener little, the coarse heaviness of external form, cast iron fastener high-altitude is not portable, and mounting or dismounting efficient is low, the labour intensity height; The damage of very easily getting rusty, often extremely can't dismantle because of becoming rusty, cause every batch of service wear rate up to 10%, maintenance rate 15%, increase construction cost, find that through literature search China Patent No. is: 87103729 prior art, name is called: fast cruciform fastening for falsework, and this technology readme is: a kind of cruciform fastening for falsework that is used for the steel pipe cross junction of builing industry scaffold has a montant clamp; A chock, this chock is hinged by pin and montant clamp, but and the bottom of this chock the cambered surface of one wedging montant is arranged; Chock top can support rail cambered surface; It is characterized in that: the said montant clamp of a. comprises two with the hinged semicircular body of pin; Inversion wedge-riser flange in semicircular body and said chock hinged place has the slotted hole that slides for a boss pin on each flange, the upper end of a slotted hole in said slotted hole has in one through the circular hole greater than boss pin external diameter; B. said chock has a slotted hole chute, and the slotted hole that said boss pin passes on said slotted hole chute and the flange links together a semicircular body of chock and montant clamp slidably; C. the cambered surface of said support rail is hinged by a pin and a loam cake, and said loam cake has a cambered surface and the clamp forks of blocking vertical tube that can push down cross bar; D. the cambered surface of said support rail and the loam cake hinged place plane apart from chock against vertical tube has certain distance.This technology also comes with some shortcomings, and especially antiskid, torque resistant poor rigidity are broken easily, and the poor-performing of the load that happened suddenly is so the accident that causes scaffold to collapse because of fastener fracture takes place in construction repeatedly.
Summary of the invention: the present invention is directed to the deficiencies in the prior art and defective, a kind of antiskid fastener for building is provided, in light weight, safe and reliable, good, the high torque resistant rigidity of cling property is big, good destructibility resistance can repeatedly be used repeatedly, and the life-span is long, toughness is big, is to replace traditional architecture fastener fastener, function admirable.The present invention is made up of two branch fasteners, each divides the following fastener small end in the fastener to be connected with eyelet bolt, big end is connected with the upper fastener that has gap and thrust surface, the mode of the material that adopts himself between two branch fasteners by the stone roller riveting connect also can be nimbly and freely with arbitrarily angled rotation.In two branch fasteners, the joint face of a following fastener is gone out a macropore, joint face of fastener is also gone out a macropore and macropore is washed into the flange crossette under another, crossette is inserted in the macropore, with the method for grinding riveting two following fasteners are riveted together, and have certain clearance, it can be rotated freely.The two earholes outside of following fastener axle bed has the riveted joint strong point, presents the arc that matches with the steel pipe cylindrical in the middle of the upper fastener, and its curved surfaces is a toothed surface.
It is very convenient that the present invention uses, and unclamps the band pad nut of branch fastener, opens a upper fastener, places a pipe, and the upper fastener that closes puts the loose joint bolt, tightens band pad nut, repeats said procedure and place another root pipe.Two branch fasteners can be flexibly and comfortably with arbitrarily angled rotation, satisfies that two steel pipe needs are fixed into instructions for use at any angle on the steel pipe scaffold.When fastener was worked, fastener was by the loose joint bolt up and down, and band fills up nut screwing clamping, and the arc toothed surface that is provided with on the fastener is six teeth up and down, tightly stings pipe, and it is clamped, and makes fastener bear bigger antiskid, tensile strength like this.
The present invention has substantive distinguishing features and marked improvement, the present invention makes fastener reduce the part number, reduce the cost, and because of be self material flange thickness greater than tubular rivet thickness, so increased tensile strength, the torque resistant rigidity improves greatly, compare with traditional building buckle, have more safety, reliable, structural strength of the present invention is better than traditional building buckle greatly.

Two fens fasteners of Fig. 3 grind the riveting connection diagram
The specific embodiment: as Fig. 1, Fig. 2 and shown in Figure 3, the present invention is made up of two branch fasteners 1,2, each divides following fastener 3,4 small ends in the fastener to be connected with eyelet bolt 5, big end is connected with the upper fastener 10,11 that has gap and thrust surface, grind riveting between two branch fasteners 1,2 and connect, and with arbitrarily angled rotation.In two branch fasteners 1,2, the joint face of a following fastener 3 is gone out a macropore 6, and joint face of fastener 4 is also gone out a macropore 7 under another, macropore 7 is washed into flange crossette 8, crossette 8 is inserted in the macropore 6, two following fasteners 3,4 is riveted together, and has certain clearance.The two earholes outside of following fastener 3,4 axle beds has the riveted joint strong point, presents the arc that matches with the steel pipe cylindrical in the middle of the upper fastener 10,11, and its curved surfaces is a toothed surface 9.The arc toothed surface 9 that is provided with on the upper fastener 10,11 is six teeth.
