Detailed Description

The square shaft 3 is bent into a square frame by using flat steel with the thickness of 3mm, and the bent opening is welded. The distance between the opposite sides of the four outer vertical surfaces is equal to the width of the I-shaped steel beam 6, so that the two beam holding moments 4 just clamp the lower wing of the I-shaped steel beam 6 after assembly. When the ventilation pipe 8 is hoisted to the I-steel girder, the height of the square shaft 3 is 80 mm; the distance between the centers of the two holes of the upper half part and the upper side is 20 mm; the distance between the center of the four holes on the lower half part and the lower edge is 20 mm. When the ventilation pipe 8 passes through the main beam and is hoisted to the upper secondary beam, the height of the square shaft 3 is the sum of the height of the I-steel main beam minus the height of the secondary beam and 80 mm. Six holes on the four vertical surfaces of the square shaft 3 are all 13mm in diameter and are used for an upper bolt 5 and a lower bolt 7 of M12 to pass through.

The beam holding moment 4 is bent into an inverted L shape by using 5mm thick flat steel, a hole with the diameter of 13mm is arranged on the lower vertical limb and is matched with the square shaft 3, the upper horizontal limb is inclined upwards, the upper inclined angle is the same as the inner wing surface inclined angle of the matched I-shaped steel beam, and the two beam holding moments 4 are exactly hung and clamped on the I-shaped steel beam 6 by using the upper bolt 5.

The side clamping plate 1 is bent into a step shape by flat steel with the thickness of 3 mm. The upper vertical limb is provided with a hole with the diameter of 13mm and is connected with the square shaft 3 by a lower bolt 7: the lower vertical limb has a 13mm diameter hole and is attached to the lower jaw 2 by means of M12 vertical bolt 9. Triangular ribs 10 with the thickness of 3mm are welded on one sides of the upper vertical limbs and the transverse web plates.

The lower clamping plate 2 is formed by cutting flat steel with the thickness of 3mm into a whole head, and holes with the diameter of 13mm are arranged at two ends and are connected with the clamping plates 1 at two sides.
