When the connecting steel pipe is used for connecting two steel pipes, the two cylinders are perpendicular to each other, and the stress is more uniform.
Furthermore, an annular boss is arranged in the middle of the side wall of the connecting steel pipe, and the outer diameter of the annular boss is larger than that of the steel pipe. When avoiding using, the connection steel pipe falls inside the steel pipe.
Furthermore, the outer wall of the connecting steel pipe is provided with sleeves in a threaded connection mode, the two sides of the annular boss are provided with sleeves in a threaded connection mode, one ends, close to the steel pipe, of the sleeves are provided with annular top plates, and the inner diameter of each annular top plate is larger than the inner diameter of the steel pipe and smaller than the outer diameter of the steel pipe. Because the size of L type slot is greater than the cylinder, can appear rocking, inconvenient dismantlement again if too tight, consequently set up annular roof can be used annular roof top is tight the cylinder.
Furthermore, the other end of the sleeve is externally connected with an annular connecting plate, and the annular connecting plates are fixed through bolts. In the case of high safety requirements or long service life, the fastening can be further secured by the bolt connection.
Furthermore, the sleeve on the two sides of the annular boss is in different screwing directions in threaded connection.
Further, the surface of the L-shaped groove, which is in contact with the cylinder, is set to be an arc surface. When using annular roof top is tight, the contact surface is the arcwall face, and firm effect is better.
The utility model has the advantages that: simple structure, easy and simple to handle's connecting piece improves the security performance, and reduces installation time, improves work efficiency.

Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
Referring to fig. 1-4, the utility model relates to a connection structure between prefabricated steel pipes of an external scaffold, which comprises a first steel pipe and a second steel pipe 2, wherein inner walls of two ends of the first steel pipe 1 and the second steel pipe 2 are both fixedly provided with a cylinder 101;
the connecting piece is for connecting steel pipe 3, all sets up a pair of L type slot 301 that corresponds the setting on the lateral wall at 3 both ends of connection steel pipe, and the width of L type slot 301 slightly is greater than the external diameter of cylinder 101, and the external diameter of connecting steel pipe 3 slightly is less than the internal diameter of steel pipe. This allows the cylinder 101 to be placed in the L-shaped channel 301. The position of the cylinder 101 is to ensure that the connecting steel pipe 3 connects two steel pipes, and the specific position is set according to actual requirements. Taking the connecting steel pipe 3 as 210mm as an example, the vertical distance between the column 101 and the near end face of the steel pipe is 65 mm.
Further, L-shaped grooves 301 connecting one ends of the steel pipes 3 are provided on the front and rear side surfaces, and L-shaped grooves 301 at the other ends are provided on the left and right side surfaces. When the two steel pipes are connected by the connecting steel pipe 3, the two cylinders 101 are perpendicular to each other, so that the stress is more uniform.
Further, an annular boss 302 is arranged in the middle of the side wall of the connecting steel pipe 3, and the outer diameter of the annular boss 302 is larger than that of the steel pipe. When avoiding using, inside connecting steel pipe 3 fell the steel pipe.
