Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As Figure 1-Figure 5, a kind of enhanced brace steel post of the utility model, including I-steel 1 and channel steel 2, it is described
I-steel 1 includes the first wing plate 3 and the second wing plate 4, and the first wing plate 3 and the second wing plate 4 are set as arc arch shape in the same direction, the slot
Steel 2 is set to the side of 4 indent of the first wing plate 3 or the second wing plate of arc arch shape, will be under the effect of 1 stress Duan great pressure of I-steel
Arc is generated, the first wing plate 3 and the second wing plate 4 is made to form the arc arch shape in same direction, channel steel 2 uses and is rolled into arc arch shape,
Channel steel 2 is installed on to the side of 4 indent of the first wing plate 3 or the second wing plate of arc arch shape, arc arch shape and the channel steel 2 of I-steel 1
The whole resistance structure of arc arch shape group arch in pairs, is arranged vertical rib plate 8, in the two sides of I-steel 1 between 2 arch of I-steel 1 and channel steel
Setting reinforcement block 7 is used to support in slot, and two sides are rolled into arc arch shape channel steel, is increased tangential counter-force and is improved bending resistance, is pressurizeed
Prewelding arc arch shape channel steel, stores prestressing force, improves 8 times than traditional straight steel column external force resistance forward direction, lateral 1 times of raising.It is double
Arch support steel column specification has 3m, 4m, 5m, 6m, 7m, and I-steel 1 uses No. 16, No. 18, No. 20b, 22b I-steel large size pressure
Power machine is pressed into arc arch shape.Channel steel 2 uses No. 8, No. 10, No. 12.6, and channel steel length is the 70% of 1 length of I-steel, arc arch shape slot
Steel reinforces 6 tons or more and rolls.When the rock frontal impact steel column of avalanche, arc plays powerful resistant function, big
When the rock soil of amount presses to steel rope net, ring network, the resistance structure of steel column effectively bears the external force of tension and compression and distortion, keeps away
Exempt to cause heavy losses, effectively increases the protective action of steel rope net, ring network.
Reinforcing rib is connected between first wing plate 3 and the second wing plate 4, the reinforcing rib includes at least two first party
To slanted bar muscle 5 and at least two second direction slanted bar muscle 6, first direction slanted bar muscle 5 and second direction slanted bar muscle 6 are along I-steel 1
Length direction continuously intersects to form reinforcement structure from beginning to end.Continuous head and the tail cross means not only first direction slanted bar muscle 5 and second party
Intersect from beginning to end to slanted bar muscle 6, and same head and the tail intersect between adjacent said rib so that I-steel whole length direction all by
The support resistant function of reinforcing rib is capable of forming continuous continual reinforcement structure, avoids apparent bending resistance weakness zone, and
The reinforcing rib being obliquely installed can play good buffer function when being pressurized, and greatly enhance the bending resistance of steel column, mention
The safety protection function of high steel rope net, ring network, intersection described herein had both included as shown in Figure 3 space crossed, were also wrapped
Include level-crossing as shown in Figure 4.
In example 1, as shown in figure 3, the first direction slanted bar muscle 5 is located at I-steel 1 wherein in a side channel, institute
It states second direction slanted bar muscle 6 to be located in 1 other side slot of I-steel, the first direction slanted bar muscle 5 and second direction of two side channels are oblique
Muscle 6 forms the reinforcement structure.First direction slanted bar muscle 5 and second direction slanted bar muscle 6 are arranged in a staggered manner respectively in I-steel 1
Two side channels in, and make that first direction slanted bar muscle 5 and second direction slanted bar muscle 6 spatially form that head and the tail intersect it is continuous not
Disconnected reinforcement structure, this setting method can largely save the material of reinforcing rib, substantially reduce production cost, and embodiment one is this
Preferred forms are arranged in reinforcing rib in application.
Embodiment two is another embodiment of reinforcing rib, as shown in figure 4, the first direction slanted bar muscle 5 and the
Two direction slanted bar muscle 6, which are located in the same side channel of I-steel 1, forms the reinforcement structure, and the reinforcement structure is symmetrically disposed on I-shaped
In two side channels of steel 1.First direction slanted bar muscle 5 and second direction slanted bar muscle 6 are arranged in the same side channel of I-steel 1 to be formed and added
Strong structure, the reinforcement structure can be both separately set in one of side channel, but there are two side channel bendings resistance are unbalanced
Defect, can also be symmetrically arranged in two side channels of I-steel 1, making in its two side channel that all there is equally distributed reinforcement
Structure, this embodiment structure is most firm, and bending resistance effect is best, but needs to expend a large amount of reinforcing rib material.
In order to reduce the consumptive material of reinforcing rib, the angle between the first direction slanted bar muscle 5 and the first wing plate 3 is 20~40
DEG C, the angle between the second direction slanted bar muscle 6 and the second wing plate 4 is 20~40 DEG C.It proves through a large number of experiments, when
Angle between one direction slanted bar muscle 5 and the first wing plate 3 is 20~40 DEG C, the second direction slanted bar muscle 6 and the second wing plate 4 it
Between angle be 20~40 DEG C, can in the case where controlling reinforcing rib consumptive material, while be able to maintain good bending resistance with
Protective capacities.
