Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a steel structure variable cross-section transition node. Background Technology

[0002] In industrial multi-story projects, the building height varies greatly due to the building's function. During construction, steel columns with the same cross-sectional dimensions are usually selected as the support columns. However, because of the building's function, the upper floor experiences less stress than the lower floor, and the upper floor does not need to use columns of the same size as the lower floor for support. Therefore, while ensuring that the required height-to-length ratio is met, in order to save materials, the upper floor columns can use steel columns with smaller cross-sectional dimensions than the lower floor columns.

[0003] Since the lower and upper columns have different cross-sectional dimensions, a variable cross-section transition node is urgently needed at the connection between the upper and lower columns to fix them together. Utility Model Content

[0004] In view of this, the present invention provides a steel structure variable cross-section conversion node to solve the problem of fixing and connecting upper and lower columns with different cross-sectional dimensions.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] According to an embodiment of the present invention, a steel structure variable cross-section conversion node is provided, including: a connection component 1.

[0027] Specifically, the connecting assembly 1 includes a first connecting member 101 and a second connecting member 102. The first connecting member 101 and the second connecting member 102 have cavities. One end of the second connecting member 102 is disposed in the cavity of the first connecting member 101. There is a gap between the inner sidewall of the first connecting member 101 and the outer sidewall of the second connecting member 102.

One end of the second connecting member 102 is fixedly connected to the first partition 2. The gap is configured as a first grouting area 3. A second grouting area 4 is configured in the cavity of the second connecting member 102. The sidewall of the second connecting member 102 has an overflow hole 5. The first grouting area 3 and the second grouting area 4 are connected through the overflow hole 5.

[0028] In this embodiment, the first connecting member 101 and the second connecting member 102 are rectangular steel columns, with the first connecting member 101 being the lower steel column and the second connecting member 102 being the upper steel column. The cross-sectional dimension of the first connecting member 101 is larger than that of the second connecting member 102. Both the first connecting member 101 and the second connecting member 102 have cavities.

The lower end of the second connecting member 102 is welded and fixed to the upper surface of the first partition 2. The first partition 2 can support the second connecting member 102. Because the cross-sectional dimension of the first connecting member 101 is larger than that of the second connecting member 102, the inner wall of the first connecting member 101 and the second connecting member 102 are connected. There is a gap between the outer walls of the connector 102. The inner wall of the first connector 101, the outer wall of the second connector 102, and the first partition 2 form a first grouting area 3. When concrete is poured into the first grouting area 3, the first connector 101 and the second connector 102 can be cast and fixed.

Preferably, overflow holes 5 are provided on all four sides of the side wall of the second connector 102. The first grouting area 3 is interconnected with the second grouting area 4 through the overflow hole 5. When concrete is poured into the first grouting area 3, the concrete in the first grouting area 3 will flow into the second grouting area 4 through the overflow hole 5. Similarly, when concrete is poured into the second grouting area 4, the concrete in the second grouting area 4 will flow into the first grouting area 3 through the overflow hole 5.

The cover plate 10 can close the first grouting area 3. At the same time, the cover plate 10 increases the connection point of the first connector 101 and the second connector 102, and improves the connection strength of the first connector 101 and the second connector 102.

[0046] In this embodiment, as Figure 1 As shown, the cover plate 10 has an exhaust hole 8 that communicates with the first grouting area 3. The exhaust hole 8 can discharge air from the first grouting area 3 during grouting.

This bonding force, combined with the shear resistance of the studs 11, allows the first connector 101 and the concrete to form an integral structure.

[0049] Preferably, each inner sidewall of the first connector 101 is provided with three rows of studs 11, each row of studs 11 having six studs 11, the six studs 11 being from... Figure 2The spacing is evenly distributed from top to bottom.
