Abstract
The invention relates to a fastener for fastening scaffolds during construction technology, in particular to a universal fastener capable of firmly and conveniently fastening steel pipes with various calibers. The fastener comprises a substrate and a cover plate hinged with the substrate; and the front and back of the substrate are provided with more than two antiskid salient points, preferably four antiskid salient points. The substrate is provided with a plurality of salient points, so the strength of the fastener is improved, contact points of the fastener with the steel pipes are more, and the antiskid performance of the fastener is greatly improved. More importantly, the positions and sizes of the salient points distributed on the substrate can adapt to different calibers, and the salient points are matched with beveled edges on the two sides of the substrate and the cover plate to form different fastening nodes according to different calibers so as to effective fasten the steel pipes, so the fastener is universal for the steel pipes with various calibers.
Description
Technical field
When the present invention relates to a kind of building operations scaffold is carried out fastening fastener, particularly a kind of can to the steel pipe of various calibers all can be firmly, fastening universal fastener easily.
Background technology
In building operations, often need build steel pipe scaffold, and building by fastener of steel pipe scaffold connects with fastening.The cover plate that scaffold clasp is hinged by the substrate that is mutually certain angle up and down and with substrate is formed, the steel pipe that is fixedly clamped of the turn by bolt, nut between substrate and cover plate during use.Existing fastener can not be general, and promptly the steel pipe of specific caliber must carry out fasteningly with fastener corresponding with it, otherwise fastener can not really connect locking with steel pipe.They have so just influenced the personnel's that scaffold erecting operating efficiency, because must remove to seek the fastener of different model at the steel pipe of different tube diameters size; And enterprise produces and equips the fastener of various different models, can improve the use cost of fastener.
Summary of the invention
The technical problem that the present invention need solve is: at existing fastener can not be general deficiency, can be applicable to various different tube diameters and intensity height, the scaffold steel plate punching press fastener that non-skid property is good and provide a kind of.
The technical solution adopted in the present invention: the present invention includes substrate and reach the cover plate that is hinged with substrate, be equipped with anti-skidding salient point on the front of substrate and the reverse side, the quantity of anti-skidding salient point is more than 2.
As above-mentioned preferred version, the quantity of anti-skidding salient point is 4.
Beneficial effect of the present invention: because of the present invention is provided with a plurality of salient points on substrate, not only increased the intensity of fastener, and more, increased the non-skid property of fastener greatly with the contact point of steel pipe.The more important thing is, its position of the salient point that distributes on the substrate can adapt to different calibers with size, these salient points cooperate with hypotenuse, the cover plate on substrate both sides, form different fastening nodes according to different calibers, steel pipe is carried out effectively fastening, so this fastener all can be general for the steel pipe of various calibers.
Description of drawings
Fig. 1 is the front schematic view of substrate of the present invention;
Fig. 2 is the reverse side schematic diagram of substrate of the present invention;
Fig. 3 is the schematic diagram of this fastener assembling different tube diameters steel pipe.
The specific embodiment
Referring to accompanying drawing, the present invention includes substrate 1 and reach the cover plate 2 that is hinged with substrate 1, be equipped with anti-skidding salient point 3 on the front of substrate 1 and the reverse side, the quantity of anti-skidding salient point 3 is more than 2.Salient point quantity among the figure on the substrate is 4.These salient points 3 cooperate with hypotenuse 4, the cover plate 2 on substrate both sides, form different fastening nodes according to different calibers, so all can be effectively fastening to the steel pipe of different tube diameters.Referring to Fig. 3, by the perpendicular type fastener set that fastener is formed, be respectively fitted with the steel pipe of 42mm and 48mm caliber in the fastener, all can firm grip.Sample of the present invention detects through national building engineering quality supervision inspection center, and its every index all meets national standard.
