[0002] In the field of municipal housing construction, in order to ensure the smooth progress of each construction process, scaffolding is generally set up as a working platform. Among them, the most commonly used is the steel pipe scaffolding, which usually uses a number of horizontal pipes and a number of vertical pipes, which are cross-arranged into a grid-like, frame-like main structure. At each node, fasteners are used to connect and fix each other. After the construction is completed, it can be safely dismantled in reverse order according to the corresponding installation steps.
[0003] During the erection of steel pipe scaffolding, since the horizontal pipes and vertical pipes are often not on the same horizontal or vertical plane, in order to adapt to this situation, the fasteners used, such as rotating fasteners, right-angle fasteners and butt fasteners, etc., are often not on the same horizontal or vertical plane for the various parts that play a connecting role, resulting in looseness due to large torque during use, causing safety hazards. In addition, the fasteners are heavy in weight, and when the construction operators operate improperly or overload, it is also easy to cause safety accidents such as scaffolding tilting and deformation.

[0007] Furthermore, a through hole is provided in the middle of the flat connecting portion.
[0008] Furthermore, the connecting member includes a pin rod, the front end of which is fixedly connected to a stop plate, the outer wall of the rear end of the pin rod is provided with a blind hole extending radially along the pin rod, an elastic pin is installed in the blind hole, and the elastic pin can be squeezed and retracted into the blind hole.
[0009] Furthermore, the rear side surface of the flat connecting part on the rear side is fixedly connected with an extension tube, and one side of the extension tube is provided with a radial pin hole penetrating the inner and outer side walls thereof, and the pin rod sequentially penetrates the through holes on the front and rear sides from front to back and extends into the extension tube, and the elastic pin extends from the radial pin hole, and the stop plate abuts against the front side surface of the flat connecting part on the front side.
[0010] Furthermore, the outer diameter of the pin rod and the inner diameter of the extension tube are both equal to the diameter of the through hole.
[0011] Furthermore, the thickness of the flat connecting portion is half of the outer diameter of the horizontal tube and the vertical tube.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model divides each horizontal and vertical pipe into a plurality of pipe sections, and each two adjacent pipe sections are fixedly connected by a flat connecting portion. During the erection of the steel pipe scaffold, when connecting the corresponding horizontal and vertical pipes, the two corresponding flat connecting portions at the nodes are overlapped one after the other, and then detachably connected together by a connecting piece, so that the horizontal and vertical pipes can be located on the same horizontal or vertical plane, and installation and disassembly are very convenient, and the torsion borne is small. In addition, the simple structure effectively reduces the dead weight, reduces the safety hazards caused by looseness, tilting and deformation of the scaffold, etc., thereby ensuring safe construction.

[0020] In the present invention, a through hole 10 is provided in the middle of the flat connecting portion 3 .
[0021] In the utility model, the connecting member 4 includes a pin rod 5, the front end of the pin rod 5 is fixedly connected to a stopper plate 6, the outer wall of the rear end of the pin rod 5 is provided with a blind hole extending along the radial direction of the pin rod 5, and an elastic pin 7 is installed in the blind hole, and the elastic pin 7 can be squeezed and retracted into the blind hole.
[0022] Thus, disassembly is achieved by squeezing, that is, applying external force to press the elastic latch 7 so that it retreats into the blind hole, that is, pulling out the pin rod 5.
[0023] In the utility model, the rear side surface of the flat connecting portion 3 on the rear side is fixedly connected with an extension tube 8, and one side of the extension tube 8 is provided with a radial pin hole 9 penetrating the inner and outer side walls thereof, and the pin rod 5 successively penetrates the through holes 10 on the front and rear sides from front to back and extends into the extension tube 8. At this time, the elastic pin 7 elastically extends out and extends from the radial pin hole 9. At this point, the pin rod 5 is fixed in the extension tube 8, so that the corresponding horizontal tube 1 and vertical tube 2 are fixedly connected together, and the stopper 6 abuts against the front side surface of the flat connecting portion 3 on the front side.
[0024] In the present invention, the outer diameter of the pin rod 5 and the inner diameter of the extension tube 8 are both equal to the diameter of the through hole 10, so as to facilitate the insertion of the pin rod 5 and prevent the pin rod 5 from shaking.
[0025] In the present invention, the thickness of the flat connecting portion 3 is half of the outer diameter of the horizontal tube 1 and the vertical tube 2. Therefore, the two corresponding flat connecting portions 3 are overlapped one after the other, so that the horizontal tube 1 and the vertical tube 2 can be located in the same horizontal or vertical plane.

[0028] Then, the pin rod 5 is passed through the through holes 10 on the front and rear sides from front to back in sequence and extended into the extension tube 8. At this time, the elastic pin 7 elastically extends out and extends from the radial pin hole 9. At this point, the pin rod 5 is fixed in the extension tube 8, so that the corresponding two flat connecting parts 3 are fixedly connected together.
[0029] After the corresponding two flat connecting parts 3 at each node are connected according to the above method, the corresponding transverse tube 1 and vertical tube 2 can be fixedly connected together.
