Description

Steel Pipe Scaffolding {STEEL PIPE SCAFFOLDING}

TECHNICAL FIELD The present invention relates to a coupling structure of a scaffold and a bonding method thereof, and more particularly, to a coupling structure of a steel pipe scaffold for easily coupling a longitudinal scaffold and a lateral scaffold using a cross linker.

Typically, scaffolding is equipment to be entangled with long wood, iron pipes, etc. to facilitate work in high places, such as wall tops and ceilings having single- and multi-layered structures, for example at construction sites. These scaffolds must be very easy to assemble to speed up the construction process. When assembling the scaffolding with such a long wood or iron pipe, a clamp is used to combine the horizontal scaffold placed in the horizontal direction and the vertical scaffold placed in the vertical direction for shortening and robustness of the assembly time. Such a scaffold fixing clamp is shown in Utility Model Registration No. 20-0222883 (a scaffold fixing tee clamp) (hereinafter referred to as "prior art") registered 2001.02.24.

However, the scaffold fixing clamps disclosed in the prior art have a configuration in which two clamp plates and a plurality of bolts and nuts are used to couple longitudinal scaffolds and transverse scaffolds each formed in a cylindrical shape to assemble the scaffold. It takes a lot of time. The bolt is fastened through a fastening hole formed in a bracket formed at the corner of two clamps located at the upper and lower sides of the longitudinal scaffold and the transverse scaffold, respectively. Therefore, when assembling the scaffold using the scaffold fixing clamp disclosed in the prior art takes a lot of time, there is a problem that the assembly process is complicated and the work efficiency is not good.

Accordingly, it is an object of the present invention to provide a steel pipe scaffold that can be very usefully used in construction sites by a simple assembly process.

It is another object of the present invention to provide a steel pipe scaffold that is assembled with a longitudinal scaffold and a transverse scaffold using a cross steel pipe coupler having female threads therein.

Steel pipe scaffolding of the present invention for achieving the above object is provided with a plurality of cross couplers in which a female thread is formed in the hollow and the coupling spheres are arranged in a cross shape. One end of the transverse scaffold having screw threads at both ends is fastened to one side hollow coupling tool in the horizontal direction of the cross coupler, and the other end of the cross scaffold is the other hollow coupling of another cross coupler adjacent in the horizontal direction. Is fastened to the sphere. At this time, the screw thread formed on the sock end of the transverse scaffold is preferably formed so that the rotation directions are opposite to each other so as to be fastened to the hollow coupler of the two horizontal couplers adjacent to the horizontal by one direction rotation of the scaffold. In addition, a cross section is formed on one end of the hollow coupler of the cross coupler and the other side of the hollow coupler of the neighboring cross coupler in the vertical direction formed with a screw thread formed at both ends.

Such a structure can simplify the assembly process of the scaffold by assembling the scaffold which is very useful for the construction site by combining the horizontal scaffold and the longitudinal scaffold positioned by the cross coupler. In addition, by combining the lateral scaffolding and the longitudinal scaffolding in the form of assembling the screw it is possible to minimize the phenomenon that the scaffold is separated or flow caused by the external force can have a high holding force.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings in which: FIG. It should be understood, however, that the present invention may be embodied in many different forms and should not be limited to the described embodiments. It should be noted that the following various embodiments are for the purpose of description and to fully convey the spirit of the invention to those skilled in the art. It should also be noted that detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention are omitted.

1 is a view showing the assembly configuration of a steel pipe scaffolding according to a preferred embodiment of the present invention. Referring to FIG. 1, a state in which a longitudinal scaffold 12 and a transverse scaffold 14 is coupled to the left and right coupling units of the cross coupler 18 is illustrated. Screws are formed at the sock ends of the longitudinal scaffolds 12 and the transverse scaffolds 14 shown in FIG. In addition, female threads are formed on the inner circumferential surface of each coupling tool of the T-type coupler 16 and the cross-fasteners 18. In FIG. 1, an example of fastening a horizontal scaffold 14 and a horizontal scaffold 14 positioned at one side of the horizontal scaffold 12 by using the T-type coupler 16 in the left and right end regions is illustrated. (16) is not required to be used, it is also possible to use a cross fastener 18.

The steel pipe scaffold configured as described above raises the scaffold vertically as shown in FIG. 1 by screwing the longitudinal scaffolds 12 and the transverse scaffolds 14 using the T-type coupler 16 and the cross coupler 18. I can go. In addition, even though external force is applied by assembling the scaffold pipes by fastening the male screw formed at the ends of the longitudinal scaffolds 12 and the transverse scaffolds 14 to the female screw formed on the inner circumferential surface of the coupler of the couplers 16 and 18. It is possible to prevent phenomena such as dislocation and departure. The assembly between the longitudinal scaffold 12 and the transverse scaffold 14 and the cross coupler 18 shown in FIG. 1 will be more clearly understood by the following description.

Referring to FIG. 2, male threads are formed at both ends 13 and 15 of the longitudinal scaffold 12. At this time, the direction of the male screw is preferably formed opposite to each other. In addition, male threads are also formed at both ends 17 and 19 of the lateral scaffold 14, and the directions of the screws formed at the sock ends are formed to be opposite to each other. It is good to fix the outside of the scaffold with a pipe wrench or the like so as to turn like a turnbuckle when rotating from the top to the bottom side. Therefore, the right end 17 is a right hand screw and the left end 19 is a left hand screw. Finally, the cross fasteners 18 are formed with coupling holes 20 and 22 formed with female threads in the hollows on the upper and lower sides of the vertical direction and the left and right sides of the horizontal direction, respectively. The opposite direction of the female thread formed in the coupler on both sides of is formed.

The scaffold assembly process of FIG. 1 will be briefly described with reference to FIGS. 2 and 3.

In this state, the cross coupler 18 located in the vertical scaffolds 12, the cross coupler 18 and the vertical scaffold 12 in the form of the cross scaffold 18 and the cross located in the neighboring vertical scaffold When the sock ends 17 and 19 of the lateral scaffold 14 are positioned in the coupler 20 between the coupler 18 and rotated in one direction, they are fastened like a turnbuckle. That is, the male threads located at both terminals 17 and 19 of the lateral scaffold 14 are fastened and assembled to the coupling coupler 20 located in the horizontal direction of the cross coupler 18 and the neighboring cross coupler 18. do. By the above method, the longitudinal scaffold 12 and the horizontal scaffold 14 are fastened to the coupler 22 formed on the vertical upper and lower sides of the cross coupler 18 and the coupler 20 formed on the horizontal left and right sides. By combining, the completed scaffold can be assembled as shown in FIG. On the other hand, the assembly process of the aspect ratio and the aspect ratio of the T-type coupler of Figure 3 is the same as the cross coupler.

Therefore, the process is simplified by only assembling the scaffold using only a longitudinal cross-linking scaffold and a cross-linking cross-linked with a female thread inside the upper and lower sides, and a male thread at both ends thereof. In addition, by making the scaffold by screwing the steel pipe is less affected by the external force than fixing the clamp on the outside of the steel pipe can be used more stably the scaffold.

As described above, the present invention is simple to manufacture the steel pipe scaffolding by fastening the male screw formed in the sock end of the longitudinal and transverse scaffolding to the couplers formed with female threads in the upper and lower sides and the left and right sides of the cross coupler to influence the external force. There is an advantage that can easily make steel pipe scaffolding hardly receives.
