Description

Technical Field

[0001] The present application relates to the technical field of steel structures, and in particular to a steel structure beam. Background Art

[0002] With the development of society and the advancement of science and technology, the demand for large buildings such as high-rise buildings, long-span bridges and large industrial plants is increasing. In these buildings, steel beams are often used as the main load-bearing parts and are usually I-shaped.

[0003] When the length of the steel structure beam is not enough, two steel structures are often welded together to increase the length of the steel structure beam. However, for temporary buildings, the use of welding is not easy during dismantling, and the connection parts need to be destroyed, which will cause the steel to melt or deform, making the reusability of the steel structure beam low.

[0033] Reference Figure 2 and Figure 3 Specifically, each first connection assembly 3 includes a first connection part 31 and a first plug rod 32. The number of the first connection part 31 is one, and the number of the first plug rods 32 is two. The first connection part 31 is in the shape of a rod, which can be a round rod or a square rod. The first plug rod 32 is in the shape of a round rod. The two first plug rods 32 are respectively integrally formed at two ends of the first connection part 31 that are far away from each other. The two first plug rods 32 are parallel to each other, and the axis direction of the first plug rod 32 is perpendicular to the length direction of the first connection part 31. The ends of the first wing plates 11 of the two steel beam bodies 1 that are close to each other are each provided with a first through hole 8 for the first plug rod 32 to slide through in a direction perpendicular to the plate surface of the first wing plate 11.

[0034] When the two first wing panels 11 abut against each other, the two first insertion rods 32 can be respectively passed through the first through holes 8 into the assembly space 2, and the first connecting portion 31 simultaneously abuts against the side of the two first wing panels 11 facing away from the assembly space 2, so that the first connecting portion 31 and the first insertion rod 32 jointly buckle the two first wing panels 11.

[0035] Reference Figure 2 and Figure 3 Each second connecting member includes a second connecting portion 41, a second plug rod 42 and a locking member 43. The number of the second connecting portion 41 is one, the number of the second plug rods 42 is two, the number and position of the locking member 43 correspond to the second plug rods 42 one by one, the second connecting portion 41 is in the shape of a rod, which can be a round rod or a square rod, the second plug rod 42 is in the shape of a round rod, the two second plug rods 42 are respectively integrally formed at the two ends of the second connecting portion 41 that are far away from each other, the two second plug rods 42 are parallel to each other, the axis direction of the second plug rod 42 is perpendicular to the length direction of the first connecting portion 31, and the locking member 43 is arranged on the corresponding second plug rod 42. The ends of the second wing plates 12 of the two steel beam bodies 1 that are close to each other are each provided with a second through hole 9 for the second plug rod 42 and the locking member 43 to pass through together in a direction perpendicular to the surface of the second wing plate 12.

[0036] Reference Figure 3 and Figure 4 , wherein the position of the first through hole 8 corresponds to the position of the second through hole 9, the first plug rod 32 corresponds to the second plug rod 42 one by one, the outer diameter of the first plug rod 32 is larger than the outer diameter of the second plug rod 42, and the end of the first plug rod 32 away from the first connecting portion 31 is provided with a slot 6 for coaxial insertion of the second plug rod 42, so that when the first plug rod 32 and the second plug rod 42 both enter the assembly space 2, the two second plug rods 42 in the same second connecting component 4 can be coaxially inserted into the two first plug rods 32 in the same first connecting component 3 respectively.

[0037] The locking member 43 includes a limiting portion 431 and a locking cover 432. The limiting portion 431 is annular and coaxially fixedly sleeved on the outer wall of the second plug rod 42, and the outer diameter of the limiting portion 431 is smaller than the outer diameter of the first plug rod 32 and larger than the outer diameter of the second plug rod 42. The locking cover 432 is a circular cover, and the outer diameter of the locking cover 432 is larger than the outer diameter of the first plug rod 32. The aperture of the second through hole 9 is consistent with the outer diameter of the locking cover 432, so that the locking cover 432 can pass through the second through hole 9 to penetrate the second wing plate 12. The locking cover 432 is coaxially slidably sleeved on the outer wall of the second plug rod 42, and the locking cover 432 can coaxially rotate on the outer wall of the second plug rod 42 and slide along the axis direction of the second plug rod 42, and the sliding position of the locking cover 432 is located between the limiting portion 431 and the second connecting portion 41.

[0038] The locking cover 432 has a connecting cavity 5 coaxially formed at one end away from the second connecting portion 41. The connecting cavity 5 is opposite to the second plug rod 42. The inner diameter of the locking cover 432 at the connecting cavity 5 is consistent with the outer diameter of the first plug rod 32. When the locking cover 432 moves away from the second connecting portion 41, it can coaxially enclose the limiting portion 431 through the connecting cavity 5. The locking cover 432 is provided with threads at the inner wall of the connecting cavity 5 along the axis direction of the second plug rod 42, and the outer wall of the first plug rod 32 is also provided with threads along its own axis direction.

When the locking cover 432 moves until the limiting portion 431 abuts against the inner wall of the connecting cavity 5 close to one end of the second connecting portion 41, the first plug rod 32 and the second plug rod 42 are relatively locked, limiting the movement of the first plug rod 32 on the first wing plate 11 and limiting the movement of the second plug rod 42 on the second wing plate 12, so as to connect the two adjacent first wing plates 11 and the two adjacent second wing plates 12. In addition, in other embodiments, in order to facilitate clamping or holding of the locking cover 432, the exterior of the locking cover 432 may be provided with a vertical striped rough structure, or may be provided in a polygonal shape, so that the locking cover 432 is not prone to slipping when being rotated.

[0041] The stopper 73 is in the shape of a nut and is threadedly sleeved on the corresponding third plug rod 72. When the third plug rod 72 passes through the waist plate 13, the stopper 73 is removed. When two third plug rods 72 pass through two waist plates 13 respectively and the third connecting portion 71 abuts against one side of the waist plate 13, the stopper 73 is threadedly sleeved on the third plug rod 72 and abuts against the other side of the waist plate 13, so that the two waist plates 13 are clamped between the third connecting portion 71 and the stopper 73. In this embodiment, the third connecting assembly 7 is provided with two groups along the height direction of the waist plate 13, and the plugging directions of the third plug rods 72 in the two groups of the third connecting assembly 7 are opposite to each other, so as to improve the bending resistance of the waist plate 13.
