Abstract
The present invention relates to an anti-skid fastener for buildings, which belongs to the technical field of a part of building machinery. The present invention is composed of two sub fasteners, wherein the small end of a lower fastener in each sub fastener is connected with a swing bolt, and the big end is connected with an upper fastener which is provided with a gap and an anti-thrust surface; the two sub fasteners are riveted and are rotated in arbitrary angles. The present invention has the advantages that the number of the parts of the fastener is reduced by the present invention, and the cost is reduced; in addition, because the flanging thickness of the material of the present invention is larger than the thickness of a hollow rivet, the tensile strength is improved, and the torque resisting rigidity is greatly improved; compared with traditional fasteners for buildings, the present invention also has the advantages of safety and reliability, and the structural strength of the present invention is largely superior to the traditional fasteners for buildings.
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 the circular hole of an internal diameter 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 includes: first fen fastener, second fen fastener, each divides first time fastener, second time fastener small end in the fastener to be connected with eyelet bolt, big end is connected with first upper fastener that has gap and thrust surface, second upper fastener, first fen fastener, ground riveting between the fastener in second minute and connect, and with arbitrarily angled rotation.
In first fen fastener, the second fen fastener, the joint face of first time fastener is gone out first macropore, and the joint face of second time fastener is gone out second macropore, second macropore is washed into the flange crossette, crossette is inserted in first macropore, and two first time fasteners, second time fastener are riveted together, and have the gap.
The two earholes outside of first time fastener, second time fastener axle bed has the riveted joint strong point, presents the arc that matches with the steel pipe cylindrical in the middle of first upper fastener, second upper fastener, and its curved surfaces is a toothed surface.
The arc toothed surface that is provided with on first upper fastener, second upper fastener is six teeth.
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.

The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the present invention includes: first fen fastener 1, second fen fastener 2, each divides the first time fastener 3 in fastener, second time fastener 4 small end to be connected with eyelet bolt 5, big end is connected with first upper fastener 10, second upper fastener 11 that have gap and thrust surface, first fen fastener 1, ground riveting between the fastener 2 in second minute and connect, and with arbitrarily angled rotation.
In first fen fastener 1, the second fen fastener 2, the joint face of first time fastener 3 is gone out first macropore 6, the joint face of second time fastener 4 is gone out second macropore 7, second macropore 7 is washed into flange crossette 8, crossette 8 is inserted in first macropore 6, two first time fasteners 3, second time fastener 4 are riveted together, and have the gap.
The two earholes outside of first time fastener 3, second time fastener 4 axle bed has the riveted joint strong point, presents the arc that matches with the steel pipe cylindrical in the middle of first upper fastener 10, second upper fastener 11, and its curved surfaces is a toothed surface 9.
