The side end that plate and corner brace are located in main joist groove is fastened by bolt, in the horizontal ends and false keel of the female part
Another side end of fixed plate and corner brace is fastened by bolt.
In the present invention, the fixed plate that the false keel connects with main joist short transverse port is equipped with inclined plate,
One end of the inclined plate is mutually fixed with the fixed plate on false keel, and main joist two sides inclined plate phase triangular in shape is fixed, the master
The joint of the inclined plate inclined plate of two sides is equipped with lifting rope on keel, which is equipped with sash weight.
Compared with prior art, implement the end structure of this steel construction girder in the utility model with beneficial below
Effect: it is mutually fixed together between major-minor keel by components such as right-angled trapezium part, female part, corner braces, wherein right-angled trapezium part
The downward stress of false keel can be effectively accepted, the part of right-angled trapezium has better crushing resistance compared with common corner brace
Can, avoid deformation；Female part is placed in the groove of false keel and leans with main joist simultaneously, can effectively prevent pair
The fixed plate of keel two sides generates deformation, and the both ends of corner brace fit with the fixed plate on main joist, false keel respectively, it is ensured that main
Right angle fixed relationship between false keel will not generate deviation；The inclined plate of main joist two sides connects in triangle, and what is restrained each other is same
When also can judge whether false keel has occurred positional shift between main joist by observing the position of sash weight.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
The end structure of this steel construction girder as shown in Figure 1, including main joist 1, false keel 2, main joist 1, secondary dragon
Bone 2 is that the two sides of length direction are equipped with the channel steel of fixed plate 3, and the two sides in T shape for being fixed on main joist 1 of false keel 2 are fixed
On plate, the fixed plate of 2 side of false keel is flushed with the port in 1 short transverse of main joist, the fixed plate on 2 other side of false keel
Right-angled trapezium fixing piece 4, two right-angle sides point of the right-angled trapezium fixing piece 4 are equipped between the fixed plate of 1 two sides of main joist
It is not fixed mutually with the fixed plate on false keel 2 and main joist 1 by bolt, female part 5 is equipped in the groove of false keel 2, this is recessed
