Description
Technical field:
The utility model relates to a kind of coupling arrangement of scaffold, particularly relates to a kind of cartridge type scaffold fastener.
Technical background:
Set up complex process when the fastener of a large amount of steel pipe scaffolds that use supports at present, vertical load poor reliability.Effect was better when the bowl fastening type steel pipe scaffold was used to support, and when still being used for external scaffolding, its resistance to overturning is poor, needed a large amount of braces keep balance.Though the scaffold of other type can satisfy the pin hand simultaneously and support two kinds of functions, its design is unreasonable, is not too heavy, waste material, and the cost height is exactly that tensile strength is low, damages easily.
Summary of the invention:
The purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, and a kind of saving material is provided, the cartridge type scaffold fastener that mechanical strength is big.
For achieving the above object, the fastener of the utility model steel pipe scaffold comprise main fastener and with the auxiliary fastener of its snapping, described main fastener is that the periphery of drum shape body is shaped on four tenons that equidistantly distribute, this tenon is made up of the clamp of justifying the outwardly directed fin of barrel-shaped body and this fin end by oneself, and described clamp is up-small and down-big trapezoidal shape; One side of described auxiliary fastener is shaped on the groove that matches with above-mentioned tenon, and auxiliary fastener is shaped on the protruding pipe that is used for the stay pipe connection at the relative opposite side of this groove.Help guaranteeing the mechanical strength of this fastener like this and save material.Described clamp can be to stretch the arbitrary shape that forms from the fin end to both sides.As straight plate shape, arc, semicircle, circle etc.
As optimization, the clamp of described tenon end is internally-oriented arc or export-oriented arc, and the groove of auxiliary fastener matches equally with it.The application point of the snapping face power of major-minor fastener distributes rationally like this, connects closely behind the snapping, helps anti-skidding and strengthens tensile strength behind the snapping.
As optimization, the part that described auxiliary fastener is shaped on groove is disc, and a side of this disk is shaped on the groove that matches with above-mentioned tenon equally, and the lower ending opening of this groove, upper end closed, opposite side are shaped on the protruding pipe that is used for the stay pipe connection.Help strengthening the mechanical strength of auxiliary fastener like this.
As optimization, the integrated disc portions of described auxiliary fastener has the curved surface identical with groove.Help saving material like this, alleviate deadweight.
As optimization, described auxiliary fastener all is shaped on axial hollow hole with both sides below groove.So both help saving material, and can not influence structural strength again.
As optimization, the drum shape body of described main fastener middle part is hollow.So both help saving material, and can not influence structural strength again.
After adopting technique scheme, under the effect of gravity load or horizontal loading, produce engagement force between the main fastener tenon of the fastener of the utility model steel pipe scaffold and the contact surface of auxiliary fastener groove, hammer force and the increase of vertical load and increase of engagement force when installing.Every group of tenon and groove all can form independently rock-steady structure under the effect of engagement force, thereby obtain reliable resistance to overturning.Main fastener can be connected on the column tube during use, auxiliary fastener is connected on the transverse tube.It is rational in infrastructure, can give full play to the strength character of material, existing fastener can bear bigger load under similarity condition, the stress surface of snapping part is big, connect firmly, tensile strength is big, owing to be shaped on hollow hole in the appropriate location of main fastener and secondary fastener, can save steel greatly, reduces deadweight, reduces cost and improve overall mechanical strength again.
