Description
Technical field
The utility model relates to scaffold field, especially relates to a kind of direct insertion slip-off preventing scaffold.
Background technology
Scaffold refers to that job site is the various supports that operative also solves vertically and horizontal transport is set up.The generic term on building circle, refers to building site be used in the higher place that cannot directly construct of exterior wall, interior decoration or floor height.Work up and down mainly for constructor or perimeter security net is gone along with sb. to guard him and high-altitude installation component etc., be exactly plainly build a framework, scaffold makes material to be had usually: bamboo and wood, steel pipe or synthetic materials etc.Some engineering is also worked as template with scaffold and is used, and the department such as this external advertising, municipal administration, traffic road and bridge, mine is also extensively used.
The steel pipe scaffold that traditional pin hand cradle uses in a large number mainly contains fastener type and the large class of bowl fastening type two, but because the reasons such as design principle, geometry, material selection and manufacturing process exist many weak points, such as overlap, dismounting speed is slow, low in conjunction with rigidity, safety and stability is poor, and spare and accessory parts easily lose damage.
Summary of the invention
Problem to be solved in the utility model is, for above-mentioned shortcoming of the prior art, provides a kind of reliably firm in structure, and easy installation and removal, the direct insertion slip-off preventing scaffold come off can be prevented.
For solving the problem, the scheme that the utility model adopts is as follows:
A kind of direct insertion slip-off preventing scaffold, is characterized in that, comprise cross bar and vertical rod; Described cross bar two ends are respectively provided with a plug; The plug at described same cross bar two ends all has an opening, and two opening directions are 90 degree of angles; Described vertical rod one end is provided with several over brace; Draw-in groove is formed between described two often adjacent over braces; Described plug is provided with the groove mated with over brace; During installation, described opening inserts described draw-in groove, and groove is set on over brace.
The utility model abandons positioning turntable conventional in prior art, but adopts the design of over brace.Positioning turntable is higher to Steel material oneself requirement.In the process used, wheel disc easily damages, and cause cross bar to come off, scaffold collapses, and causes serious security incident.The design adopts the structure design of over brace and plug, namely avoids the weakness of wheeling disk structure, fragile, in turn ensure that scaffold is installed, convenient disassembly.When installing and using, the plug of cross bar is inserted in the draw-in groove in vertical rod between two adjacent crossbars supports, and presses downwards, make over brace top card be located in the groove of plug, because over brace is fixed in vertical rod, so the size of draw-in groove is also fixing.Even if there is the unbalanced phenomenon in cross bar two ends in use, draw-in groove also can help cross bar to tilt, and causes scaffold to collapse.Over brace and the groove matched can make cross bar to stablize, firmly be arranged in vertical rod.Because the utility model structure is simple, press so only need one to insert one when mounted, do not need too many complicated operation and too many component.
Further, according to direct insertion slip-off preventing scaffold described in the utility model, described over brace is rectangular structure; Comprise upper surface, four sides and bottom surface; Described over brace upper surface and bottom surface are square; Described over brace and vertical rod are formed in one.
Over brace is arranged to rectangular structure, cross bar is when mounted remained and to be connected with vertical rod fixed angle, the phenomenons such as loosening, rotation can not be there is.
Further, according to direct insertion slip-off preventing scaffold described in the utility model, described over brace is provided with four tapered ramp; Described tapered ramp connects upper surface and corresponding side.
On the basis of above-mentioned design, set up four tapered ramp to over brace, facilitate over brace to enter groove.
Further, according to direct insertion slip-off preventing scaffold described in the utility model, described over brace is three or five.
On the basis of above-mentioned design, over brace is set to three, and when scaffolding erecting, cross bar alternate intervals is arranged.When over brace is set to five, when scaffolding erecting, cross bar sets gradually, and arranges without the need to interval.
Further, according to direct insertion slip-off preventing scaffold described in the utility model, the width of described draw-in groove is more than or equal to the thickness of plug.
The width of draw-in groove is set greater than the thickness equaling plug, and convenient plug inserts.
Further, according to direct insertion slip-off preventing scaffold described in the utility model, the thickness that the width of described draw-in groove equals plug adds 1-3mm.
The thickness that the width of draw-in groove is preferably plug adds 1-3mm, is namely conducive to plug and inserts draw-in groove, can prevent again cross bar from tilting, coming off.
Further, according to direct insertion slip-off preventing scaffold described in the utility model, the opening part of described plug is provided with safety pin; Described safety pin comprises shank and shifting block; Described shifting block vertically connects and shank surface.
On the basis of appeal design, be provided with safety pin at the opening part of plug, cross bar be arranged on after in vertical rod, stir safety pin, close the opening of plug.
Further, according to direct insertion slip-off preventing scaffold described in the utility model, described vertical rod (2) one end is provided with sleeve pipe (21).
Technique effect of the present utility model is as follows: the utility model abandons positioning turntable conventional in prior art, but adopts the design of over brace.Positioning turntable is higher to Steel material oneself requirement.In the process used, wheel disc easily damages, and cause cross bar to come off, scaffold collapses, and causes serious security incident.The design adopts the structure design of over brace and plug, namely avoids the weakness of wheeling disk structure, fragile, in turn ensure that scaffold is installed, convenient disassembly.When installing and using, the plug of cross bar is inserted in the draw-in groove in vertical rod between two adjacent crossbars supports, and presses downwards, make over brace top card be located in the groove of plug, because over brace is fixed in vertical rod, so the size of draw-in groove is also fixing.Even if there is the unbalanced phenomenon in cross bar two ends in use, draw-in groove also can help cross bar to tilt, and causes scaffold to collapse.Over brace and the groove matched can make cross bar to stablize, firmly be arranged in vertical rod.Because the utility model structure is simple, press so only need one to insert one when mounted, do not need too many complicated operation and too many component.
