Abstract
The invention relates to a fastener of a steel pipe scaffold, which comprises a main fastener and an auxiliary fastener and is characterized by also comprising a screw rod and a screw nut, wherein the main fastener and the auxiliary fastener are both composed of two half cylinders and have approximately w-shaped cross sections; the main fastener and auxiliary fastener are movably connected into a whole and are respectively provided with a screw rod holder. The invention has the advantages that two adjacent vertical rods can be simultaneously locked, and meanwhile, the inter diameter of the fastener is set to be 48 mm, therefore, the fastener is better in fastening effect, simple in structure, convenient to operate and remarkable in economic benefit and also has the effects of reducing the labor intensity of workers, increasing the work efficiency, reducing the construction cost.
Description
Technical field
The invention belongs to the scaffold in the building operations, specifically is a kind of scaffold clasp.
Background technology
Scaffold is that various supports vertical and that the level transportation is set up are operated and solved in the job site for making things convenient for the workman.Mainly be used in the higher place that can't directly construct of exterior wall, interior decoration or floor height on the building site.Its purpose is mainly worked up and down for the constructor or peripheral safety net is safeguarded and high-altitude installation component etc. provided convenience.Existing scaffold all is to adopt horizontal, vertical steel pipe to intersect to be the cross net, and its infall adopts fastener locking.Along with high crossbeam in the engineering is more and more many, an independent vertical rod of former process using can not have been satisfied the force request of high crossbeam, generally adopts two vertical rods to support when therefore running into such situation, and the increasing vertical rod is stressed.Though then have the dynamics of the bearing problem that has solved scaffold.But the method for at present steel pipe infall in the scaffold being locked still adopts general fastener to carry out snap close; And existing general fastener can only cross bar of snap close and the situation of vertical rod intersection; Therefore so just increase fastener quantity and working strength of workers, thereby increased construction cost.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology existence, a kind of simple in structure, easy to operate steel tube scaffold clasp is provided.
The technical scheme that the present invention is adopted to achieve these goals is following:
A kind of steel tube scaffold clasp; It comprises main fastener and auxiliary fastener; It is characterized in that also comprising screw rod and nut; Said main fastener and auxiliary fastener all are made up of two half-cylinders and the cross section roughly is ' w ' shape, and said main fastener and auxiliary fastener flexibly connect and be integral, and all also are provided with screw bolt seat on main fastener and the auxiliary fastener.
A kind of steel tube scaffold clasp described in according to the present invention is characterized in that connecting through rotating shaft between said main fastener and the auxiliary fastener.
A kind of steel tube scaffold clasp described in according to the present invention, the internal diameter that it is characterized in that said semicylinder is 48mm.
A kind of steel tube scaffold clasp described in according to the present invention is characterized in that said nut is a hex nut.
Advantage of the present invention is to lock two adjacent vertical rods simultaneously; Its internal diameter is set to 48mm simultaneously; Therefore fastening effect is better; And it is simple in structure, operation has also conveniently reduced working strength of workers simultaneously, improved operating efficiency, reduced construction cost, has remarkable economic efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1-main fastener, 2-auxiliary fastener, 3-screw rod, 4-nut, 5-screw bolt seat.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is further specified, but the present invention is not limited in following embodiment.
As shown in Figure 1: a kind of steel tube scaffold clasp, it comprises main fastener 1, auxiliary fastener 2, screw rod 3 and nut 4, this nut 4 adopts hex nut.Said main fastener 1 all is made up of two half-cylinders with auxiliary fastener 2 and the cross section roughly is ' w ' shape, and said main fastener 1 flexibly connects with auxiliary fastener 2 and is integral, and all also is provided with screw bolt seat 5 on main fastener 1 and the auxiliary fastener 2.Connect through rotating shaft between main fastener 1 and the auxiliary fastener 2.Show that according to long-term construction when the internal diameter of the semicylinder of forming fastener was 48mm, it was the tightest to fit between fastener and the vertical rod, therefore fastening effect is best.All be provided with screw bolt seat 5 on main fastener and the auxiliary fastener simultaneously, screw bolt seat 5 is provided with the through hole that supplies screw rod to pass.When reality is used, cover the opposition both sides of two vertical rods respectively with main fastener and auxiliary fastener, it is fastening with nut 4 to pass two screw rods seat 5 backs with screw rod 3 then, thereby reaches the purpose of locking vertical rod.Adopt screw rod to fix here, because the cross bar of screw rod and scaffold all is to be on the horizontal plane, so screw rod played the purpose of support rail simultaneously, thereby further improved the soundness of scaffold.
