The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Example 1: the utility model discloses a concrete structure as follows:

referring to fig. 1-6, the utility model discloses a simple convenient concentric sleeve pipe of bridging of construction, include:

a connecting sleeve 2;

the outer diameter of each cross bracing steel pipe 1 can be inserted into the corresponding connecting sleeve 2 to form a concentric shaft structure, and steps are formed at the connecting positions of the cross bracing steel pipes 1 after the cross bracing steel pipes 1 are inserted into the corresponding connecting sleeves 2;

and the locking assembly is sleeved at the step and sleeved on the outer wall of the cross bracing steel pipe 1 and has an elastic structure.

A preferred technical solution of this embodiment: the locking assembly includes:

the locking port 31 is sleeved on the outer wall of the cross bracing steel pipe 1, and the locking port 31 is sleeved on the outer wall of the cross bracing steel pipe 1;

and the locking buckle 32 is screwed outside the locking port 31 and can be movably locked and loosened along the length direction of the locking port 31 to lock and loosen the locking buckle 32.
