Description

Long angle iron

This creation is about long rectangular angle irons, especially two long right angle angle irons for alignment at the inner corners. The long straight angle iron is a long strip of steel in which the two panels 11a, 11b are perpendicular to each other, at least equilaterally angled iron and unequal angle iron.

At present, the long straight angle iron on the market is as shown in the first figure. The most common one is the long angle angle iron of the concave arc at the inner corner, as shown in the second figure. However, the angle iron is unsatisfactory. For example, four long rectangular angle irons are to be welded to form a rectangle. Since the angle inside the angle iron is curved, the four corners of the rectangle are very difficult to handle, and the alignment action needs to be repeated repeatedly; sometimes even first The arc is removed to make the joints easy to align and flattened ------ without floating up due to the concave arc at the inner corner.

From the above project, a long straight angle iron appeared on the market, and the concave arc at the inner corner was simply removed. The inner corner was directly a straight angle, as shown in the third figure; however, the inner angle was The long-angled iron with no arc at the arc has insufficient rigidity and is easily bent due to the loss of the arc as a beam or a column.

Therefore, the long straight angle iron that is currently lacking on the market is a kind of strong rigidity with a long rectangular angle iron with a concave arc at the inner inner corner, and at the same time, it can have the convenience of a long straight angle iron without an arc at the inner corner. Sex.

According to the present invention, two small right-angled rectangular angle irons for alignment at the inner corner are proposed, which have the rigid rigidity of the long rectangular angle iron of the concave arc at the traditional inner corner, and can also have no arc at the inner corner. The convenience of the long rectangular angle iron.

This creation does not need to repeatedly repeat the alignment action, only one of the two small right angles for aligning the inner corners can be topped to the end; there is no case where the concave arc is pressed to the inner corner to cause the floating.

This creation is supported by two small right angles for alignment at the inner corners, and the original spacing of the two long straight angle irons to be welded is not changed due to the cooling shrinkage of the welded joints during welding.

As shown in the fourth to eighth figures, according to the present invention, a long rectangular angle iron of two small right angles h for alignment at the inner corner is proposed, which has a long right angle of the concave arc 10a at the traditional inner corner. The solid rigidity of the angle iron, at the same time, can have the convenience of the long angle iron of the arc without the arc 10b at the traditional inner corner.

The creation does not need to repeatedly repeat the alignment action, only one of the two small right angles h used for aligning the inner corners is required to be placed at the end; nor does it occur when the concave arc 10a is pressed to the traditional inner corner to cause floating. Happening.

This creation is held by the two small right angles h aligned at the inner corners, and the original spacing of the two long straight angle irons to be welded is not changed by the cooling shrinkage of the welded joints during welding.

The two angled angles of the two small right angles h are aligned at the inner corner of the creation. The height of one of the corners, as shown in the figure h, is at least 0.1 mm, and its height is positive with the length of the long angle iron. Related.

A long strip of rectangular angle iron, regardless of the equilateral or unequal sides, or even shaped long strips of rectangular angle iron, as shown in the fourth, fifth, sixth, seventh, and eighth figures, but not limited As shown in the five figures, it is within the scope of this patent to design two or more small right-angled rectangular right angle angles for alignment at the inner corners of the example to achieve alignment and beam-column functions.
