Description

Technical Field

[0001] This application relates to the field of staircase assembly technology, and in particular to a flange connector and a steel column assembly. Background Technology

[0002] Currently, stair railings typically consist of posts and diagonal braces. The tops of the posts are usually connected to the diagonal brace via connectors. Existing connectors are generally fixed, directly connecting both ends to the posts and diagonal brace. However, stair railings generally include multiple posts and one diagonal brace. Errors in manufacturing or construction can cause the tops of the diagonal braces to not be aligned on the same slope. Using fixed connectors to connect the diagonal brace to the posts results in loose connections, posing a safety risk.

[0042] Example

[0043] Reference Figure 1 As shown, this embodiment provides a flange connector 100, including a first flange assembly and a second flange assembly. (Refer to...) Figure 2 As shown, the first flange assembly includes a first flange plate 1, a seat 2, a height adjusting member 3, and a first connecting lug 4. The first flange plate 1 is connected to the seat 2, specifically extending outwards from the contour surface of the seat 2. The first flange plate 1 is used for connection to a stair post or diagonal brace. (Refer to...) Figure 4 As shown, the height adjustment assembly includes a first pad 31, a second pad 32, and an adjusting bolt 33. The first pad 31 is slidably connected to the seat 2, and the second pad 32 is connected to the first connecting ear 4. The first pad 31 has a first inclined surface 311, and the second pad 32 has a second inclined surface 321 that mates with the first inclined surface 311. The adjusting bolt 33 is threadedly connected to the seat 2 and abuts against the first pad 31. When the adjusting bolt 33 pushes the first pad 31 to move, the height of the second pad 32 can be adjusted under the guidance of the first inclined surface 311 and the second inclined surface 321, thereby adjusting the relative height between the seat 2 and the first connecting ear 4.

[0044] Continue to refer to Figure 1 As shown, the second flange assembly includes a second flange plate 5 and a second connecting lug 6. The second flange plate 5 is connected to the second connecting lug 6. The second connecting lug 6 is hinged to the first connecting lug 4. The second flange plate 5 is used to connect to the stair upright or diagonal brace. The angle between the first flange plate 1 and the second flange plate 5 can be adjusted by the hinged first connecting lug 4 and the second connecting lug 6, thereby compensating for the angular error between the stair upright and the diagonal brace. The relative height between the first connecting lug 4 and the first flange plate 1 can be adjusted by the height adjustment component 3, thereby adjusting the relative height between the first flange plate 1 and the second flange plate 5, thereby compensating for the height error between the stair upright and the diagonal brace.

[0045] The flange connector 100 provided in this embodiment can adjust the relative height of the first flange plate 1 and the second flange plate 5 through the height adjustment component, thereby compensating for the height dimension of the steel column structure 200; the hinged first connecting lug 4 and second connecting lug 6 can compensate for the angle between the steel column structure 200 and the diagonal bar; thus making the connection reliability between the flange connector 100 and the column and diagonal bar higher.

[0046] Specifically, the top of the seat 2 has an opening that extends into the seat 2 to form a receiving cavity. The height adjustment component is located within the receiving cavity, and the first connecting ear 4 is movably placed within the receiving cavity along its extension direction and extends outward from the opening. Placing the height adjustment component within the receiving cavity forms a concealed structure, improving the aesthetics of the installed staircase and protecting the height adjustment component from accidental activation.

[0047] Specifically, the receiving cavity includes an adjustment cavity 21 and a moving cavity 22; one end of the moving cavity 22 is connected to an opening, and the other end is connected to the adjustment cavity 21; the height adjustment member 3 is placed inside the adjustment cavity 21; the first connecting ear 4 includes a moving part 41, which passes through the moving cavity 22, and the outer contour of the moving part 41 coincides with the inner contour of the moving cavity 22. In this embodiment, both the outer contour of the moving part 41 and the inner wheel of the moving cavity 22 are rectangular structures, providing guidance for the movement of the first connecting ear 4.

[0048] Specifically, the side wall of the seat 2 is provided with a groove 23, and a partition 24 is provided between the groove 23 and the adjustment cavity 21. The partition 24 is provided with a threaded hole for connecting to the adjusting bolt 33. This allows the adjusting bolt 33 to be housed within the groove 23, improving aesthetics and providing protection for the bolt 33. In this embodiment, two adjusting bolts 33 are provided, each abutting against both sides of the first pad 31, thereby limiting the position of the first pad 31. When the position of the first pad 31 needs to be adjusted, the screwing depth of the two adjusting bolts 33 is adjusted respectively.

[0049] Specifically, the bottom of the adjustment cavity 21 is provided with a first T-shaped groove 71, and the bottom of the first pad 31 is provided with a first T-shaped slider 312 that slides in cooperation with the first T-shaped groove 71;

[0050] The first pad 31 has a second T-shaped groove 313 at the top, and the second pad 32 has a second T-shaped slider 322 at the bottom that engages with the second T-shaped teeth.

[0051] Specifically, the first flange plate 1 has a through hole in the middle; the bottom of the seat 2 is detachably connected to a base plate 7, and the top surface of the base plate 7 serves as the bottom surface of the adjustment cavity 21, that is, the first T-shaped slide groove 71 is set on the top of the base plate 7. When assembling the first flange assembly, the first connecting lug 4, the height adjustment component 3 and the base plate 7 are assembled first; then they are inserted into the receiving cavity from the bottom of the seat 2, and the base plate 7 is fixed to the bottom of the seat 2 using screws or other structures.

The connecting plate 202 is connected to the stair step surface by expansion bolts, the third flange plate 201 is connected to a first flange plate 1, and the second flange plate 5 is connected to the stair diagonal brace.

[0054] The steel column assembly provided in this embodiment can adjust the relative height of the first flange plate 1 and the second flange plate 5 through the height adjustment component, thereby compensating for the height dimension of the steel column structure 200; the hinged first connecting lug 4 and second connecting lug 6 can compensate for the angle between the steel column structure 200 and the diagonal rod; thus making the connection reliability between the flange connector 100 and the column and diagonal rod higher.

[0055] Specifically, the steel column structure 200 has a reserved section 203 at one end facing the third flange plate 201; the base 2 has a reserved groove 25; after the reserved section 203 is inserted into the reserved groove 25, the third flange fits against the first flange. During assembly, the reserved section 203 can be inserted into the reserved groove 25 first for initial positioning, and then the first flange and the third flange can be connected.

[0056] It should be noted that when multiple steel column structures 200 are connected to a diagonal rod through flange connectors 100, the angles of each flange connector 100 will remain fixed.
