Detailed description of the invention
The detailed description of the invention work of stiffener assembly is installed on floor a kind of to this utility model with embodiment below in conjunction with the accompanying drawings
Describe in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
As Figure 1-4, stiffener assembly is installed, including floor reinforcing plate 4, described floor in a kind of floor of the present utility model
The longitudinal cross-section of reinforcing plate 4 is " u "-shaped, and reinforcing plate 4 both ends, described floor are fixed with first crossbeam 1 and second cross beam 2 respectively
Connecting, described floor reinforcing plate 4 basal surface is fixedly connected on the upper surface on floor, the upper end and first of described floor reinforcing plate 4
Longeron 3 is fixing to be connected.So, it is connected owing to floor reinforcing plate 4 all has with first crossbeam 1, second cross beam 2 and the first longeron 3, ground
Plate reinforcing plate 4 obtains the part of 3 good rigidlies of first crossbeam 1, second cross beam the 2, first longeron 3 and supports, floor reinforcing plate 4
Good fixing, because the structural rigidity of rigidity first crossbeam 1, second cross beam 2 and the first longeron 3 is good, structure can also be obtained
Stability is strong, can be greatly promoted the installation strength of floor reinforcing plate 4, promotes rigidity, and owing to floor reinforcing plate 4 uses
" u "-shaped structure, floor reinforcing plate 4 forms box body structure with floor, and the structural strength of box body structure is high, and good stability increases
Adding the floor structural strength in this position, advantage in terms of existing technologies is: the structure of floor reinforcing plate 4 position
Intensity height, good rigidly, it is greatly promoted floor and in the structural strength of this position and structural stability is effectively ensured.
Stiffener assembly is installed, as shown in Figures 1 to 4, in previously described technical scheme in a kind of floor of the present utility model
On the basis of it may also is that be provided with at least one welding in described floor reinforcing plate 4 to dodge hole 5.So, by adding on floor
On strong plate 4, welding is set and dodges hole 5, when floor reinforcing plate 4 is welded on floor, can except floor reinforcing plate 4 marginal position
To weld, welding is dodged the position in hole 5 and can also be welded, and increases bonding area, it is ensured that weld strength, improves floor
The structural strength of reinforcing plate 4 position and rigidity.Preferred technical scheme is: described welding is dodged hole 5 and is provided with three, three
Dodge hole described in individual and be arranged on described floor reinforcing plate and floor welded position.So,
Full section re-starts description: the effect dodging hole is not the bonding area increasing floor reinforcing plate 4 with floor, is kept away
The solder joint allowed is welding floor, the second longeron and nutplate.Floor reinforcing plate 4 is connected by 2 layers of solder joint with floor；Pass through again
Dodge 3 layers of solder joint of hole location, floor is coupled together with the second longeron and nutplate.Arrange 2 layers of solder joint and 3 layers of solder joint,
Increase installation region connection welding number, reduce solder joint stress near mount point, promote intensity；Meanwhile, 4 laminates are by the different numbers of plies
Solder joint couples together, and installed surface rigidity gets a promotion.Ensure structural strength, meanwhile, also greatly reduce floor reinforcing plate 4
Total quality, it is achieved light-weight design.
Stiffener assembly is installed, as shown in Figures 1 to 4, in previously described technical scheme in a kind of floor of the present utility model
On the basis of it may also is that on the lower surface of described floor corresponding reinforcing plate 4 position, floor be provided with the second longeron 6, described
Second longeron 6 both ends are fixed be connected with described first crossbeams 3 and described second cross beam 2 respectively.So, surface pair under floor
Answer floor reinforcing plate 4 that second longeron 6 is set, can further promote the structural strength of floor reinforcing plate 4 position, due to ground
Plate upper surface is provided with floor reinforcing plate 4, and the structural strength of floor upper surface is the most prominent, and lower surface side then intensity is relative
Weakness, is now provided with the second longeron 6 at lower surface, can effectively promote the structural strength of floor lower surface.Preferred skill
Art scheme is: the cross section of described second longeron 6 is " u "-shaped.So, " u "-shaped structure has good relative to platy structure
Structural stability, because platy structure is easy to bend, destroys structure, and " u "-shaped structure is difficult to deform, Er Qie
Two longerons 6, floor reinforcing plate 4 form box body structure with floor, and it is steady that box body structure is greatly improved structural strength, rigidity and structure
Qualitative.Preferred technical scheme is: described second longeron 6 is internally provided with nutplate 7, described nutplate 7 and the second longeron 6
Fixing connection.So, increase integral thickness, thus lift structure intensity.Most preferably technical scheme is: described nutplate 7 liang
Lateral edges position is provided with flange, and described flange is fixing with the both sides, inside of described second longeron 6 to be connected.So, flange is passed through
Fix with the second longeron 6 and be connected, flange and the bonding area of the second longeron 6 can be increased, can effectively promote the second longeron 6
Structural strength and rigidity.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and modification, these change
Enter and also should be regarded as protection domain of the present utility model with modification.
