The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example (b):
as shown in fig. 1, the utility model provides a flange type steel structure connecting structure, which is used for connecting two workpieces 6 with flange end faces, wherein the flange end faces are provided with a plurality of mounting holes uniformly distributed along the circumferential direction, the flange end faces of the two workpieces 6 are respectively nested with a first connecting body 4 and a second connecting body 2, the first connecting body 1 and the second connecting body 2 form a buckling mode, and particularly, the first connecting body 1 is nested on the second connecting body 2;
specifically, in this embodiment, the first locking portion 3 includes a first bolt and cooperates with a nut to use, the first bolt passes through the mounting hole on the flange end face, and the second locking portion 4 includes a second bolt, although the first locking portion 3 may also be a cylindrical rod body, the second locking portion 4 may also be a cylindrical rod body, and the first locking portion 3 and the second locking portion 4 may adopt other structures that are equal to the bolts, and no other cases are listed here.
Combining fig. 1 and fig. 2:
the first connecting body 1 and the second connecting body 2 are provided with a plurality of first fixing parts along the axial direction of a workpiece 6, and the first fixing parts are formed by first locking parts 3;
the first connecting body 1 and the second connecting body 2 are provided with a plurality of second fixing parts along the radial direction of the workpiece 6, and the second connecting parts are formed by second locking parts 4;
when the first locking part 3 and the second locking part 4 are bolts, the first bolt is perpendicular to the axis of the second bolt, so that the workpiece 6 is fixed in two directions in the axial direction and the radial direction;
when two workpieces 6 have a tendency to depart from each other in the axial direction, the first fixing part (i.e., the first locking part 3) is subjected to tensile force, and the second fixing part (i.e., the second locking part 4) is subjected to shearing force;
when two workpieces 6 generate a dislocation trend in the radial direction, the first fixing part (namely the first locking part 3) bears shearing force, and the second fixing part (namely the second locking part 4) bears pulling force;
therefore, at least one fixing part bears the tensile force, the capacity of bearing the shearing force of the fixing part in the other direction is improved, and finally the connecting strength of the two workpieces 6 is improved.
With reference to fig. 3, for the second locking portion 4, it is implemented by using a connection structure of bolts, that is, an internal threaded hole 21 matched with the second bolt is formed on the second connecting body 2, a through hole for the second bolt to pass through is formed on the first connecting body 1, both the internal threaded hole 21 and the through hole are circumferentially and uniformly distributed, and in consideration of certain error and other factors in the installation process, the structure of the waist-shaped hole 21 is used here, so that the second bolt has a certain axial displacement space in the first connecting body 1, and can be ensured to be matched with the internal threaded hole 21, it should be noted that when the second bolt is locked, the second bolt needs to be tightly pressed against the outer wall of the first connecting body 1, and thus stable fixation is formed; if the second locking portion 4 adopts a columnar rod structure, the rod needs to be fixed with the first connecting body 1 and the second connecting body 2 at the same time.
Further, considering that the wall thickness of the first connecting body 1 and the second connecting body 2 is relatively small with respect to the length of the first locking portion 3, in actual implementation, a plurality of turns of the second locking portion 4 may be provided, i.e., the second bolt has a plurality (2 are shown in the figure) as viewed in the axial direction as shown in fig. 2 or 3.
Furthermore, the end parts, close to the mounting holes, of the two workpieces 6 are provided with positioning holes, positioning sleeves 5 are arranged in the positioning holes, the first locking parts 3 (namely the first bolts) penetrate through the positioning sleeves 5, the shearing force resisting capacity of the first bolts is further improved, when the locking device is actually used, the outer diameter of each positioning sleeve 5 is the same as the inner diameter of each positioning hole, the inner diameter of each positioning sleeve 5 is not smaller than the nominal diameter of each first bolt, and the length of each positioning sleeve 5 is not larger than the sum of the depths of the two positioning holes.
