Abstract
The utility model relates to a ring-wedge fastening for fastening construction scaffolds. A crossing steel pipe is sheathed by means of a crossing ring and wedgewise fastened by an arc wedge member whose frictional force is used to fix the position of the steel pipe of a scaffold. The utility model has the advantages of simple structure, single manufacturing technique, low cost, reasonable structure, no screw bolt and pin, simple and convenient assembly and disassembly, time saving, labour saving and high durability.
Description
The utility model relates to a kind of builing industry hardware component, and the new type scaffold fastener that especially a kind of building site is used is in order to fixing steel pipe scaffold.
At present, China building operations troop, generally adopting straight tube is the scaffold that the steel pipe of 48mm makes, steel pipe need not be processed, and is fixed with fastener.This fastener is made up of 3 steel-castings, two pins and two bolts; Its complex structure, processing link is many, cost is high.It is many lost time to twist bolt during use, and spiral shell buckle be infected with mortar after, embroider erosion easily and not quick detachable, even can not dismantle.Also also having a kind of scaffold in addition is that steel pipe with 48mm processes; On the long montant of 3m, be welded with the bowl seat and load onto movable bowl cover; The steel pawl of burn-oning at the long cross bar two ends of 1.8m and 1.2m, during installation the steel pawl on the cross bar stretched in the bowl seat on the montant, and overlap fixing and the formation scaffold with movable bowl, the size of this scaffold can not free adjustment, its bowl seat, bowl cover and steel pawl easy deformation in handling process, in case distortion, whole steel pipe can not use, thereby do not have promotional value.
The purpose of this utility model is to design a kind of novel use scaffold clasp flexibly in order to overcome above-mentioned the deficiencies in the prior art part, to reduce cost, improves work efficiency.
Task of the present utility model is implemented as follows, and it mainly comprises a crossed loops and two arc wedges, and crossed loops is to be interconnected by two uncovered ring backs to form.The arc wedge is the arc long slab of two sideband gradients, with the angle of cut place of ring set at steel pipe, the arc wedge is inserted the indentation, there of uncovered ring during use, gets final product the arc wedge is urgent again.
Ring-wedge fastening can also be made and be made up of a two-tube cover and arc wedge, two-tube cover comprises three uncovered rings, respectively connect vertical each other with it or tilt a uncovered ring on the indentation, there both sides of uncovered ring, during use, after two-tube cover is enclosed within the steel pipe infall, also be that the indentation, there wedging that the arc wedge inserts two uncovered rings is got final product.More than can be fixedly connected between the uncovered ring of two kinds of Ring-wedge fastenings, also can flexibly connect, so that the steel pipe of the fixing different angles of cut, above-mentioned two kinds of embodiment utilize the wedge effect to make uncovered ring and arc wedge close, and steel pipe held tightly, rely on the fixing scaffold of frictional force between Ring-wedge fastening and steel pipe.
The utility model has the following advantages compared with the prior art: this Ring-wedge fastening is simple in structure, manufacturing process is single, cost is low, easy to use, simple to operate, as long as hitting the arc wedge round about can finish, save man-hour during installation or removal, improve work efficiency, it is rational in infrastructure, and intensity is big, and is durable in use.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail, as shown in Figures 1 and 2, it mainly is made up of a crossed loops and two arc wedges 2, wherein crossed loops comprises two uncovered rings 1, it is an annular slab with openend, two vertical each other or connections of tilting in uncovered ring back.As shown in Figures 3 and 4, arc wedge 2 is the long wedges of the gradient along its length arc in both sides; With the infall of uncovered ring set, the arc wedge is inserted the indentation, there of uncovered ring during use, get final product the arc wedge is urgent again at scaffolding steel pipe.
As Fig. 5 and shown in Figure 6, Ring-wedge fastening can also be made up of a two-tube cover and an arc wedge 2, wherein two-tube cover comprises three uncovered rings 1, the uncovered ring that respectively connects while or inclination equal angular vertical on the indentation, there both sides of uncovered ring 1 with it, during use, two-tube cover is enclosed within the infall of scaffolding steel pipe, and the indentation, there wedging that arc wedge 2 is inserted two uncovered rings gets final product.
The all available steel of each part of Ring-wedge fastening, other metals or high strength artificial material are made.Can cast and also can cast the compacting work.Ring-wedge fastening can be used as part and uses, and also can be welded on the steel pipe, with anti-lost.
