Abstract
The utility model discloses a hollow cold -formed steel of improved generation, including the connecting plate, the connecting plate about the both ends symmetry be provided with the backup pad, the lower extreme of backup pad is connected with the collateral branch fagging on and, the lower extreme of collateral branch fagging is connected with the bottom suspension fagging, and all is provided with the U type section of bending on collateral branch fagging and the bottom suspension fagging, adopt clod wash technology integrated into one piece between connecting plate, last backup pad, collateral branch fagging, the U type section of bending and the bottom suspension fagging, the utility model discloses a shaped steel is through increasing the U type section of bending on collateral branch fagging and bottom suspension fagging to the effectual bending resistance who strengthens shaped steel has strengthened bearing capacity moreover greatly, compares in C shaped steel having obvious performance advantage with under the steel volume on an equal basis, and the collateral branch fagging can also provide better performance through outside welding strengthening muscle.
Description
Technical field
The utility model is related to shaped steel technical field, specially a kind of hollow cold-rolled forming section of modified.
Background technology
Shaped steel is the steel commonly used in modern industry and building industry, and existing shaped steel is mainly I-steel, C-type steel etc.,
But part shaped steel is not suitable for hot rolling technology processing, it is necessary to be processed using cold bending process, but existing cold bending process is processed
Shaped steel be all generally simple shape shaped steel, structure design is simultaneously unreasonable, therefore bearing capacity and bending resistance are all smaller,
Have become engineering constraint technology development bottleneck, therefore study and develop can be provided under identical steel using amount preferably carrying
The new cold bend type steel of ability and bending resistance is necessary, and a kind of hollow cold-rolled forming section of modified is we provided for this.
Utility model content
The purpose of this utility model is to provide a kind of hollow cold-rolled forming section of modified, to solve to be carried in above-mentioned background technology
The problem for going out.
To achieve the above object, the utility model provides following technical scheme：
A kind of hollow cold-rolled forming section of modified, including connecting plate, the left and right two ends of the connecting plate are symmetrically arranged with branch
Fagging, and the lower end of upper backup pad is connected with collateral fagging, the lower end of the collateral fagging is connected with lower supporting plate, and collateral support
U-shaped bending section, the connecting plate, upper backup pad, collateral fagging, U-shaped bending section and lower branch are provided with plate and lower supporting plate
It is integrally formed using cold bending process between fagging.
Preferably, lightening hole is provided with the connecting plate, and lightening hole is mounting hole.
Preferably, connecting hole is provided with the upper backup pad, and the lower end of lower supporting plate is provided with lower connecting hole.
Preferably, two pairs of U-shaped bending sections are at least placed with the collateral fagging, and between collateral fagging and lower supporting plate
Connected using arc.
Preferably, the vertical range between the connecting plate and upper backup pad is no more than the twice for connecting plate thickness, and connects
Angle between fishplate bar and upper backup pad is 105 to 145 degree.
Compared with prior art, the beneficial effects of the utility model are：The shaped steel of the utility model design is by collateral
Increase U-shaped bending section on fagging and lower supporting plate, so as to effectively enhance the bending resistance of shaped steel, and greatly strengthen and hold
Loading capability, has obvious performance advantage compared to C-type steel under equal steel using amount, and collateral fagging can also be by outside
Welding reinforcement provides better performance.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1 connecting plate, 2 lightening holes, 3 upper backup pads, connecting hole, 5 collateral faggings, 6U types bending section, 7 times supports on 4
Plate, 8 times connecting holes.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1 is referred to, the utility model provides a kind of technical scheme：
A kind of hollow cold-rolled forming section of modified, including connecting plate 1, the left and right two ends of connecting plate 1 are symmetrically arranged with support
Plate 3, and the lower end of upper backup pad 3 is connected with collateral fagging 5, the lower end of collateral fagging 5 is connected with lower supporting plate 7, and collateral support
Be provided with U-shaped bending section 6 on plate 5 and lower supporting plate 7, connecting plate 1, upper backup pad 3, collateral fagging 5, U-shaped bending section 6 and under
It is integrally formed using cold bending process between supporting plate 7, lightening hole 2 is provided with connecting plate 1, and lightening hole 2 is mounting hole, upper branch
Connecting hole 4 is provided with fagging 3, and the lower end of lower supporting plate 7 is provided with lower connecting hole 8, is at least placed with collateral fagging 5
Two pairs of U-shaped bending sections 6, and connected using arc between collateral fagging 5 and lower supporting plate 7, between connecting plate 1 and upper backup pad 3
Twice of the vertical range no more than the thickness of connecting plate 1, and angle between connecting plate 1 and upper backup pad 3 be 105 to
145 degree.
The shaped steel increases U-shaped bending section 6 by collateral fagging 5 and lower supporting plate 7, so as to effectively enhance shaped steel
Bending resistance, and greatly strengthen bearing capacity, have obvious performance excellent under equal steel using amount compared to C-type steel
Gesture, and collateral fagging 5 can also provide better performance by outside weldings reinforcement.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out various changes in the case where principle of the present utility model and spirit is not departed from, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
