Embodiment

Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.

As shown in Figure 1, steel reinforced concrete column gas cabinet, comprise gas cabinet cylindrical shell 1, the barrel of described gas cabinet cylindrical shell 1 is made up of the multiple barrel lateral plates 2 be tightly connected successively, described barrel lateral plate 2 outer installment has the general column 3 and anti-rotation column 4 that play supporting role to barrel lateral plate 2, described anti-rotation column 4 outer installment has the gas cabinet claustra 5 barrel lateral plate 2 formation being held tightly to effect, prevent barrel lateral plate 2 loose causing between adjacent side plates, there is no combination force, described general column 3, anti-rotation column 4 includes shaped steel 6 and waters the concrete seven of knot on shaped steel, strengthen its rigidity, described shaped steel 6 is H profile steel, described general column 3 is 20 ~ 30, and be evenly distributed on gas cabinet cylindrical shell 1 circumferentially, described anti-rotation column 4 is 3-6, also gas cabinet cylindrical shell 1 is evenly distributed on circumferentially, make the supporting force of barrel lateral plate balanced, not easily or incline top curved by windbreak, described column, the cross section of anti-rotation column is rectangle, mate with beam steel shape, concrete is combined firmly with shaped steel.

For 30 ten thousand stere gas cabinets, its general column is preferably 28, and anti-rotation column is preferably 4, calculates respectively to Rigidity and strength, is specifically calculated as follows:

One, Rigidity Calculation:

As shown in Figure 2, set its width direction is X-direction to steel reinforced concrete column section, and its length direction is Y-direction.

(1), be then calculated as follows around the flexural rigidity enhancing of Y-axis:

(1) H profile steel moment of inertia:

I _S＝1.24×10 ⁸mm ⁴

(2) concrete column moment of inertia

I _C＝I _A-I _S＝15.02×10 ⁸-1.24×10 ⁸＝13.78×10 ⁸mm ⁴

Wherein I _afor the moment of inertia of Integral rectangular reinforced concrete upright column.

Then concrete is to being promoted to of flexural rigidity of integrated steel concrete column around Y-axis:

$\frac{E_C{I}_C+E_S{I}_S}{E_S{I}_S}-1=\frac{E_C{I}_C}{E_S{I}_S}=\frac{3\×{10}^4\×13.78\×{10}^8}{2.06\×{10}^5\×1.24\×{10}^8}\×\%=161.84\%$

(2) the flexural rigidity enhancing, around X-axis is calculated as follows:

(1) H profile steel moment of inertia:

I _S＝9.44×10 ⁸mm ⁴

(2) concrete column moment of inertia

I _C＝I _A-I _S＝44.37×10 ⁸-9.44×10 ⁸＝34.93×10 ⁸mm ⁴

Wherein I _afor the moment of inertia of Integral rectangular reinforced concrete upright column.

Then concrete is to being promoted to of flexural rigidity of integrated steel concrete column around X-axis:

$\frac{E_C{I}_C+E_S{I}_S}{E_S{I}_S}-1=\frac{E_C{I}_C}{E_S{I}_S}=\frac{3\×{10}^4\×34.93\×{10}^8}{2.06\×{10}^5\×9.44\×{10}^8}\×\%=53.89\%$

In the present embodiment, general column is preferably 28, and anti-rotation column is preferably 4, and the angle between adjacent upright posts is 11.5 °, and its Rigidity Calculation is as following table:

Above-mentioned conclusion can be found out: obvious to rigidity stiffening effect by steel reinforced concrete, on average rises to 133.6707%.If be considered as by gas cabinet being subject to uniform line load q effect, be highly H, then maximum deflection occurs in gas cabinet top, and formula is:

$f_A=\frac{q{H}^4}{8\mathrm{EI}}$

In above formula, I is moment of inertia; Q is blast.

Being reduced to the 100/133.6706=74.8% before transformation by calculating the rear amount of deflection of transformation, being reduced beyond 1/4th.
