Based on above device, the structure of the girder steel hinged joint of the embodiment of the present invention is further described through below
It is bright：
It will be appreciated by persons skilled in the art that due to first through hole 1011,3021 and second through-hole of third through-hole
1021 aperture is all higher than the bar diameter of the screw rod 501 of the first bolt 5, therefore, even if by the first plate body 101, the web of girder steel 3
302 and second fixed close between plate body 102, when the external world exerts a force to first edge of a wing 301 of girder steel 3, the web of girder steel 3
302 can also realize around being that axis carries out with first edge of a wing 301 and second edge of a wing, 303 direction parallel, vertical with web 302
Rotation.
There are many can for first through hole 1011, the structure of 3021 and second through-hole 1021 of third through-hole in embodiments of the present invention
The realization method of energy.
In the first possible implementation, as shown in Fig. 4 or Fig. 5,1011 and second through-hole 1021 of first through hole is
Extend elongated elliptical aperture in the horizontal direction, third through-hole 3021 is to extend elongated elliptical aperture, the first bolt 5 in vertical direction
Screw rod 501 can successively pass through first through hole 1011,3021 and second through-hole 1021 of third through-hole.
So set, when the power that first edge of a wing 301 of girder steel 3 is applied by the external world, the first bolt 5 is without limitation on girder steel
Relative movement between 3 302 and first plate body 101 of web, the second plate body 102, with realize girder steel 3 around with first edge of a wing
301 and second edge of a wing, 303 direction parallel, vertical with web 302 be the purpose that is rotated of axis.
It should be noted that the size of first through hole 1011, the second through-hole 1021 and third through-hole 3021 can be identical,
Can be different, it is not especially limited in embodiments of the present invention.
In second of possible realization method, as is seen in fig. 6 or fig. 7, first through hole 1011, the second through-hole 1021 and
Three through-holes 3021 are circular hole, and the size of three is identical, the area much larger than the cross section of the screw rod 501 of the first bolt 5,
The screw rod 501 of first bolt 5 can successively pass through first through hole 1011,3021 and second through-hole 1021 of third through-hole.
So set, since first through hole 1011, the second through-hole 1021 and third through-hole 3021 are circular hole, and long-range
Area in the cross section of the screw rod 501 of the first bolt 5, therefore, when the power that first edge of a wing 301 of girder steel 3 is applied by the external world
When, the first bolt 5 without limitation on the relative movement between 302 and first plate body 101 of web of girder steel 3, the second plate body 102, with
Realize that girder steel 3 is rotated around with first edge of a wing 301 and second edge of a wing, 303 direction parallel, vertical with web 302 for axis
Purpose.
In the third possible realization method, as shown in Fig. 8 or Fig. 9, first through hole 1011, the second through-hole 1021 and
Three through-holes 3021 are square hole, and the size of three is identical, the area much larger than the cross section of the screw rod 501 of the first bolt 5,
The screw rod 501 of first bolt 5 can successively pass through first through hole 1011,3021 and second through-hole 1021 of third through-hole.
So set, since first through hole 1011, the second through-hole 1021 and third through-hole 3021 are square hole, and long-range
Area in the cross section of the screw rod 501 of the first bolt 5, therefore, when the power that first edge of a wing 301 of girder steel 3 is applied by the external world
When, the first bolt 5 without limitation on the relative movement between 302 and first plate body 101 of web of girder steel 3, the second plate body 102, with
Realize that girder steel 3 is rotated around with first edge of a wing 301 and second edge of a wing, 303 direction parallel, vertical with web 302 for axis
