15mm, preferably 7.6mm, the end thickness=h2 of 13/ time leg of leg 12 on average thickness h1-, h2 are 2mm～4mm, are preferably
2.64mm, the position at average thickness h1 is preferably 15.88mm with distance L1 of leg end；
The cross section of the ribs 3 i.e. upper end of isosceles trapezoid and the difference gone to the bottom are preferably 4mm, a height of half gone to the bottom, such as
Upper end h3 is 20mm, the h4 that goes to the bottom is 24mm, high L2 is 12mm；
Screw 2 is preferably dimensioned to be M16*30；
Screw 4 is preferably dimensioned to be M16*30；
Through hole 5 is preferably dimensioned to be Φ 16.5.
The optimal size of above-mentioned a size of high-intensity special-shaped I-steel, i.e. various combining properties are optimum, in other enforcement
In example, above-mentioned size can be changed as required.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect：
1st, I-steel body 1 and ribs 3 are one-body molded, decrease welding sequence, improve door leaf working (machining) efficiency, it is ensured that
Positioning precision, reduce door leaf processing cost, it is to avoid is deformed during welding；
2nd, the bulk strength having arranged I-steel enhanced of ribs 3, in order to open screw 4 and through hole 5 at I-steel,
The transport of more convenient door leaf and assembling；
To sum up, the high-intensity special-shaped I-steel of the safeguard Steel structure door that the embodiment of the present invention provides is a kind of intensity
High, rigidity big and the high-intensity special-shaped I-steel of Integral sealing function admirable, is directly produced one-shot forming by steel mill.This high intensity
Abnormal-shaped joist steel can simplify the production technology of protective door, improve product quality and production efficiency, and enhances the anti-of protective door
Power, improves the airtight unfailing performance of safeguard, has stronger promotional value.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
