Example 1: a connecting structure for a steel structure building comprises a bolt 3 and a nut 8, wherein the bolt 3 penetrates through connecting holes 2 in a first connecting end 1 and a second connecting end 5 and then extends into a locking sleeve 7, one end of the locking sleeve 7 is connected with the nut 8 through an external thread end 10, a tensioning piece 9 is connected to the tail end of the bolt 3 in a threaded mode, and the tensioning piece 9 is located in a tensioning end 11 of the locking sleeve 7; the external thread end 10 and the tensioning end 11 are respectively arranged at two ends of the locking sleeve 7, a stepped hole 13 is formed in the locking sleeve 7, and a hole with a smaller inner diameter in the stepped hole 13 is located at one end of the locking sleeve 7 where the external thread end 10 is located; the tensioning piece 9 is of a cylinder structure with a conical end 15, and a thread structure matched with the bolt 3 is processed inside the cylinder structure; a retainer ring 14 protruding out of the surface is processed on the cylinder structure of the tightening piece 9; the tensioning end 11 is composed of arc sheets distributed at one end of the external thread end 10, and an embedded groove 12 is processed on the inner surface of each arc sheet; the bolt 3 is provided with a connecting gasket 6 at the position contacting with the inner surface of the first connecting end 1, and the connecting gasket 6 is arranged at the position connecting the nut 8 and the second connecting end 5.

On the basis of the above-mentioned embodiments, the present application continues to describe the technical features and functions of the technical features mentioned therein in detail to help those skilled in the art to fully understand the technical solutions of the present application and reproduce the same.

In the present application, the purpose is to complete the connection operation of the first connection end 1 and the second connection end 5 with the connection hole 2 by using the bolt 3 and the nut 8 and the assembly thereof, and to ensure the connection stability of the connected first connection end 1 and the second connection end 5.

As shown in fig. 1 and 2, after the connection holes 2 of the first connection end 1 and the second connection end 5 are aligned, the bolt 3 is inserted through the inner side of the first connection end 1 until it passes through the second connection end 5. A bolt gasket 4 is arranged at the contact position of the bolt 3 and the inner side surface of the first connecting end 1, and the bolt gasket 4 is sleeved on the bolt 3 before the bolt 3 passes through the first connecting end 1.

After the bolt 3 passes through the second connection end 5, the connection pad 6 is fitted over the bolt 3. The connection pad 6 is in contact with the outer side surface of the second connection terminal 5. After the connecting gasket 6 is sleeved on the bolt 3, the locking sleeve 7 is sleeved on the bolt 3 and enables the thread section on the bolt 3 to be located in the tensioning end 11. The locking sleeve 7 comprises an external thread end 10 and a tensioning end 11, wherein the tensioning end 11 is composed of a plurality of circular arc-shaped plate structures, and the circular arc-shaped plate structures are distributed on one side of the external thread end 10 and are uniformly distributed around the central axis of the external thread end 10. The inner diameter of the tensioning end 11 is greater than the diameter of the screw 3, which enables the tensioning member 9 to enter the tensioning end 11 and spread the tensioning end 11 apart.

The tensioning member 9 described in the above paragraph is configured as shown in fig. 5, and has a cylindrical structure including a tapered end 15 and a retaining ring 14. The cone-shaped end 15 is located in the screwing direction of the cylinder structure, and the retainer ring 14 is distributed on the outer surface of the cylinder structure and protrudes out of the outer surface of the cylinder structure. The tensioning element 9 is connected to the external thread on the screw 3 via a threaded bore and can be screwed into the tensioning end 11 during rotation of the screw 3.

However, before the tightening member 9 is screwed in, the nut 8 needs to be sleeved outside the locking sleeve 7. The nut 8 can be matched with the external thread end 10 on the tensioning sleeve 7 through the thread structure of the nut 8, so that the nut 8 is screwed in and locked along the outer surface of the locking sleeve 7. After the nut 8 is screwed in until the connecting gasket 6 contacts and applies a certain torque force, the bolt 3 is rotated to drive the tensioning member 9 at the end portion to be screwed in towards the direction of the nut 8, and in the screwing process, because the outer diameter of the tensioning member 9 is larger than the inner diameter formed by the tensioning ends 11, the tensioning member 9 outwards supports the arc-shaped plate body on the tensioning ends 11. The arc plate body after strutting is located the outside of nut 8, consequently can cooperate with second link 5 in order to restrict the motion of nut 8 in the axis direction of bolt 3, prevents the pine and takes off.

In the screwing process of the tensioning member 9, the annular retainer ring 14 on the outer surface is matched and clamped with the caulking groove 12 in the tensioning end 11, so that the tensioning member 9 and the bolt 3 can be prevented from loosening.
