Abstract
The utility model relates to a falsework connecting device, which comprises a joint body, wherein the end part of the joint body is used for connecting with the end part of a steel pipe; and the falsework connecting device is characterized in that a tension sleeve is arranged on the outside circumference of the fitting body, the longitudinal section of the tension sleeve is in a left square bracket shape, a clearance is radically arranged between the tension sleeve and the end part of the joint body, and outside threads are arranged on the tension sleeve. When being connected together with a steel pipe, the falsework connecting device is very convenient to operate; and the fastness of the connection between the falsework connecting device and the steel pipe is good, and the utilization ratio of the length of the steel pipe is high.
Description
Technical field
The utility model belongs to the building implements field, particularly a kind of linkage that is used to connect the steel pipe type scaffold.
Background technology
In carrying out the high-building construction process, need promote constructor's height inevitably by means of scaffold.The scaffold that adopts in the existing building construction mainly is a frame type, and the scaffold of frame type is that the steel pipe by some certain-length specifications constitutes by interlaced linking together.These steel pipes generally link together by fastener, when connecting, the end parts parallel of two steel pipes overlap joint has two linkworks in every fastener, these two linkworks snap onto the end of two steel pipes respectively, and utilize clamp nut to realize being fastenedly connected between two steel pipes.The mode of building of this scaffold has following defective: troublesome poeration when 1, building, and operating efficiency is low; The end of two steel pipes that 2, link together needs overlapping, and this has influenced the length utilization rate of steel pipe.
The utility model content
The utility model technical issues that need to address: provide a kind of when building the scaffold that constitutes by steel pipe, can improve steel pipe length utilization rate, build the guaranteed means for fastening scaffolding of the performance that is connected firmly between easy to operate, the steel pipe.
The technical scheme that addresses the above problem: a kind of means for fastening scaffolding, comprise fittings body, the end of fittings body is used for being connected with steel tube end part, on the outer peripheral face of fittings body end, be provided with cranse, vertical the cutting of cranse is " [" shape, leave the gap in cranse and fittings body end between radially, cranse is provided with external screw thread.When utilizing this linkage to scaffold erecting, described fittings body end is inserted in the link of steel pipe, the end of steel pipe is inserted in the radial clearance between cranse and the fittings body end, and can be socketed with coupling nut on the outer peripheral face of steel pipe link, have the internal thread that matches with external screw thread on the described cranse on the coupling nut.Corresponding position on steel pipe link outer peripheral face is provided with radially outwards outstanding ring-type convex body, and is provided with radially inwardly outstanding retaining edge on coupling nut.When steel pipe is connected with fittings body, cranse and fittings body end limit moving radially of steel pipe, and retaining edge and ring-type convex body are combined together to limit moving axially between steel pipe and the fittings body, make between the different steel pipes to link together securely by fittings body.
In this linkage, the end of described fittings body reaches the axial outside of cranse.
In this linkage, the end of described fittings body is tapering slightly, and its little head end is positioned at the outside of fittings body, and its stub end is positioned at cranse, and the radial clearance between this stub end and the cranse is slightly less than the thickness of steel pipe wall body.
In this linkage, described connector is " one " font.
In this linkage, described connector is " ten " font.
In this linkage, described connector is
Shape.
Therefore, the utlity model has following beneficial effect:
When steel pipe was connected with this means for fastening scaffolding, coupling nut set on the steel pipe link was threaded on the cranse by the mode of rotating, and can realize connecting fast by fittings body between the different steel pipes.Cranse and fittings body end are used to limit the radial motion of connected steel pipe, retaining edge on the coupling nut and the ring-type convex body on the steel pipe, and cranse is used to limit the axially-movable between steel pipe and the fittings body, between the different steel pipes good connectivity robustness can be arranged.The end of the different steel pipes that are connected together does not directly upwards have overlapping, has made full use of the length of steel pipe.
Description of drawings
Fig. 1 is the partial sectional view of a kind of embodiment of this means for fastening scaffolding.
Fig. 2 is the partial sectional view of the another kind of embodiment of this means for fastening scaffolding.
Fig. 3 is the partial sectional view of another embodiment of this means for fastening scaffolding.
The specific embodiment
See in the accompanying drawing that the structure of this means for fastening scaffolding is a fittings body 6, the shape of fittings body 6 have " one " font, " ten " font,
Shape.In the attended operation process of reality, can select the fittings body of different structure form for use according to concrete instructions for use.The end 3 of fittings body 6 is used for being connected with the link of steel pipe 1, and when both linked together, the end 3 of fittings body 6 was plugged in the link of steel pipe 1.
Be provided with cylindrical shape cranse 5 on 3 outer peripheral faces of the end of fittings body 6, its vertical section is that " [" shape, cranse 5 upwards has gap 7 with 3 footpaths, end of fittings body 6.The end 3 of fittings body 6 is passed cranse 5 and is reached the axial outside of cranse 5, and the part that the end 3 that can guarantee fittings body like this is inserted in the steel pipe 1 has enough length, fittings body 6 that links together with increase and the radially fastness between the steel pipe 1.
On cranse 5, have external screw thread, and the link outer peripheral face of steel pipe 1 is socketed with coupling nut 2 with gap.Coupling nut 2 is provided with radially inwardly outstanding retaining edge away from a side of steel pipe link, and is provided with radially outward outstanding ring-type convex body 4 in the corresponding position of steel pipe link outer peripheral face.When steel pipe 1 was connected with fittings body 6, the external screw thread on internal thread on the coupling nut 2 and the cranse 5 cooperated together.Under the common qualification of cranse 5, retaining edge, ring-type convex body 4, has axial stability preferably between steel pipe 1 and the fittings body 6.
The end 3 of fittings body 6 is tapering slightly, and its little head end is positioned at the outside of fittings body 6, and stub end is positioned at cranse 5, and the radial clearance between described stub end and the cranse 5 is slightly less than the thickness of steel pipe 1 wall body.When coupling nut 2 was threaded togather with cranse 5, the end of steel pipe 1 can be by in the radial clearance 7 of wedging between the end 3 of cranse 5 and fittings body.
In Fig. 1, Fig. 2, fittings body 6 is the solid structure, and fittings body 6 also can be a hollow body structure as shown in Figure 3.
