Abstract

The utility model relates to a scaffold bar without a joint button. A slotted hole (2) is arranged on a steel pipe used as the scaffold bar, wherein, the end of the steel pipe is cut into an inclined plane which is welded with a steel plate (4). A hook (5) with a circular hole (6) is arranged on the steel plate (4), the hook (5) is buckled in the slotted hole (2), and two trapezoid key plates (8) with slotted holes (7) are arranged on both sides of the hook. The key plates are compressed, screws (9) which are penetrated through the slotted holes (7) and the circular hole (6) are used for connecting two bars together. The utility model has the advantages of simple structure and convenient construction, and can decrease the construction cost and the cost of a scaffold.

Description

Scaffold bar without joint button

The utility model relates to construction work scaffold field.

Current construction work is extensive use of steel pipe scaffold especially on building engineering, this kind steel pipe scaffold must use the binding fastener when each rod member connects, therefore all have one to link operation when construction, has increased the engineering time.Link fastener Chang Yi in addition and in work progress, lose, increased construction cost and management transaction to a certain extent.

The utility model is at above-mentioned situation, proposes a kind of scaffold rod member that need not fastener connects, so one of the purpose of this utility model provides a kind of scaffold that links operation of exempting.Owing to need not use the binding fastener, therefore another purpose of the present utility model is to have reduced scaffold to make and construction cost.Another purpose of the utility model is owing to eliminated the binding fastener, reduces a large amount of loose mails and makes the easier civilization management in job site.

Main design of the present utility model is to have slotted eye on the steel pipe as the scaffold rod member, and this slotted eye can link directly in slotted eye for the rod member that links with it.

Details are as follows in conjunction with the accompanying drawings in detailed description of the present invention, wherein:

Fig. 1 is not for there being the fastener of binding scaffolding pole spare generalized section;

Fig. 2 is not for there being the fastener of binding scaffolding pole spare vertical view.

As seen from the figure, have slotted eye (2) on the montant (1), the number of slotted eye (2) and neglect the specification of steel pipe greatly and decide is the steel pipe scaffold of 48-50mm for the widely used diameter of present China, and size the best of slotted eye is 40mm * 8mm.An inclined-plane is cut in end at cross bar (3), welding one block plate (4) on the inclined-plane, and steel plate (4) is gone up an affixed hook (5).Have hole, garden (6) on the hook (5), other has two centres to have the trapezoidal key metal plate (8) of slotted eye.When implementing the utility model, earlier the hook of cross bar (2) (5) is buckled in the slotted eye (2) of montant (1), again two blocks of key metal plates (8) are inserted in the both sides of hook (5) between the steel metal plate (4) of montant (1) and cross bar (3) end, screw rod (9) passes the slotted eye (7) of key metal plate (8) and the circular hole of hook (5) links up montant and cross bar, utilize the ramp effect of key metal plate (8) and steel metal plate (4) again, fix with nut (10) after compressing the key metal plate, montant and cross bar are closely linked together.

For aufbauprinciple is described, be that example is illustrated above, but in practice of construction, the mode of binding also can be linked up with in the slotted eye (2) of cross bar (3) (please 90 ° of the clockwise commentaries on classics of Fig. 1) by montant, and two bars are closely linked with montant and cross bar.

The utility model is reasonable in design, simple structure, and easy construction, and can reduce the manufacturing cost and the operating expenses of scaffold.

Claims

1, a kind of nothing of being made by steel pipe links fastener scaffolding pole spare, of the present utility model being characterized as on the tube wall as the steel pipe of scaffold has slotted eye (2), an inclined-plane is cut in cross bar (3) end, a welding steel plate (4) on the inclined-plane, steel plate (4) is gone up an affixed hook (5), on the hook (5) hole, a garden (6) is arranged; The hook of cross bar (3) (5) is buckled into the slotted eye (2) of montant (1), the trapezoidal key plate (8) that two middle parts are provided with slotted eye (7) places the both sides of hook (5) between the steel plate (4) of montant (1) and cross bar (2), compresses the key metal plate and passes slotted eye (7) and link up with hole, garden (6) and montant and cross bar are linked up with screw rod (9).
