Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1 to 3, the present invention provides a connection joint, including a connection member a1 and a plurality of connection members B2 fixedly installed on a connection member a1, and a connection member B2 perpendicular to the connection member a1, wherein the connection joint has shapes including, but not limited to, L, T and cross, the connection member a1 is a solid structure or a tubular structure, and the connection member B2 is a solid structure or a tubular structure, when in use, if the connection member a1 is a solid structure, one end of the steel structural pipe is fitted over the connection member a1, and then the steel structural pipe is locked to the connection member a1 by means of bolts and nuts, etc., if the connection member a1 is a tubular structure, one end of the steel structural pipe is installed inside or outside the connection member a1, if the connection member B2 is a solid structure, one end of the steel structural pipe is fitted over the connection member B2, and then the steel structural pipe is locked to the connection member B2 by means of bolts and nuts, and if the connection member B2 is a tubular structure, one end of the steel.

The end of the connecting piece A1 is provided with a through hole A10.

The number of the connecting pieces B2 is 1-5.

The connecting piece B2 is provided with a through hole B20.

The connector A1 is a tubular structure, and the cross-sectional shape of the inner wall of the connector A1 includes but is not limited to rectangle. In use, the cross-sectional shape of the inner wall of the connector a1 can also be circular, regular polygon, etc., and the shape of the inner wall of the connector a1 is determined according to the shape of the steel structural pipe fitting.

The connecting piece B2 is a tubular structure, and the cross-sectional shape of the inner wall of the connecting piece B2 comprises but is not limited to a rectangle. In use, the cross-sectional shape of the inner wall of the connector B2 can also be circular, regular polygon, etc., and the shape of the inner wall of the connector B2 is determined according to the shape of the steel structural pipe fitting.

The connecting piece A1 and the connecting piece B2 are both tubular structures, and the wall thickness of the connecting piece A1 and the wall thickness of the connecting piece B2 are not less than 5 mm.

To sum up, adopt the attach fitting to dismantle the connection between the steel construction pipe fitting, improved the dismouting efficiency of steel construction building, reduced the welding work volume of steel construction building, improved steel construction material's reuse rate, avoid causing a large amount of wastes of steel construction material.
