Abstract
The invention discloses a connection fastener for a scaffold; the scaffold is provided with a vertical bar, a horizontal bar and a positioning pin; the vertical bar is provided with a connecting structure; the end of the horizontal bar is provided with a horizontal bar level fork; the connection fastener is characterized in that a connection structure on the vertical bar is a circular piece provided with a plurality of interfaces; the plurality of the interfaces are uniformly distributed on the circular piece along the circumferential direction of the vertical bar wall; the end of the horizontal bar is provided with the fork formed by an upper lug and a lower lug; the upper lug and the lower lug are provided with open slots; the fork of the horizontal bar is clamped on the circular piece; the open slots of the upper lug and the lower lug are in alignment with the interfaces to form a vertical plug hole; and the positioning pin passes through the vertical plug hole to lock the vertical bar and the horizontal bar. The connection fastener of the invention is simple to operate, saves labor, and has better practical value.
Description
Technical field
The present invention relates to a kind of assembly for scaffold for building, especially a kind of connection fastener that is used for scaffold.
Background technology
In builing industry, construction is to be assembled by assembly for scaffold with scaffold.Existing assembly for scaffold generally includes cross bar, vertical rod and connection fastener, utilize connection fastener that cross bar is fixedlyed connected with vertical rod, thereby be overlapped to form construction scaffolding, yet existing connection fastener adopts the right angle more, the loose-leaf nut fastener of butt joint.Need tighten or unclamp nut when using the mounting or dismounting of this fastener and exist disadvantage such as expend man-hour, connection fastener is easy to lose.
Summary of the invention
The purpose of this invention is to provide a kind of socket connection fastener that is used for scaffold easy and simple to handle.
Technical scheme of the present invention provides a kind of connection fastener that is used for scaffold, described scaffold has vertical rod, cross bar and alignment pin, vertical rod is provided with syndeton, be provided with the horizontal prong of cross bar in the end of cross bar, it is characterized in that: the syndeton in the described vertical rod is provided with the annular element of a plurality of interfaces for it, described a plurality of interface is evenly distributed on the annular element along the circumferencial direction of vertical rod bar wall, the end of described cross bar is provided with, the prong that following ear forms, on described, be provided with open slot on the following ear, the prong clip of described cross bar is on described annular element, on described, the open slot of following ear aligns with described interface and forms a vertical spliced eye, and described alignment pin passes this vertical spliced eye with described vertical rod and cross bar locking.
Compare with existing like product, because the present invention is provided with a plurality of interfaces and can realizes that multiposition docks with the cross bar prong in vertical rod, alignment pin passes this vertical spliced eye and vertical rod and cross bar can be locked, and is simple to operate laborsaving.Therefore, connection fastener of the present invention has more practical value in scaffold.
Content of the present invention further illustrates with the following Examples, but content of the present invention is not limited to content related among the embodiment.
Description of drawings
Fig. 1 is to use connection fastener of the present invention to connect the structural representation of scaffold upright rod and cross bar.
The specific embodiment
As shown in Figure 1, the scaffold in the present embodiment has vertical rod 1, cross bar 2 and alignment pin 3.Vertical rod 1 is provided with annular connection fastener 4, and annular connection fastener 4 is welded in the vertical rod 1, and the circumferencial direction of its upper edge vertical rod bar wall evenly is provided with eight interfaces 5, and annular element connection fastener 4 can be circle or octagon.Be provided with the horizontal prong 5 that upper and lower ear forms in the end of cross bar 2, be provided with open slot 6 on the upper and lower ear.
When using the connection scaffold upright rod of connection fastener in the embodiment of the invention and cross bar, prong 5 clips of the end of cross bar 2 of the present invention are on annular connection fastener 4, the open slot 6 of the upper and lower ear of cross bar prong aligns with the interface 5 of annular connection fastener and forms a vertical spliced eye (not shown), then alignment pin 3 is inserted in the vertical spliced eye, thereby vertical rod 1 is connected with cross bar 2.
Claims (3)
