Description

Technical Field

[0001] This utility model relates to the field of column support structure technology, and in particular to a steel-concrete column support structure. Background Technology

[0002] Inter-column bracing is a connecting component installed between adjacent columns to enhance the overall stability of a building structure, increase lateral stiffness, and effectively transfer longitudinal horizontal forces. It is commonly used in steel and steel-concrete structural bracing systems. Existing inter-column bracing structures are generally prefabricated in factories, such as cross bracing structures and K-type bracing structures. These structures are prefabricated in the factory using steel welding and are then transported to the construction site for direct installation. However, in steel-concrete structures, there are certain construction errors in the concrete columns. This results in the prefabricated bracing structure only being able to be fixed to the concrete column on one side, while the other side cannot be effectively connected due to gaps with the other concrete column. This significantly reduces the efficiency and quality of inter-column bracing construction, prolongs the construction period, and poses potential safety hazards. Utility Model Content

[0036] Reference Appendix Figure 1-6This embodiment provides a steel-concrete inter-column support structure, comprising: a main node seat 1, a secondary node seat 2, two sets of first support arms 3, two sets of second support arms 4, and several sets of positioning components 5. The main node seat 1 is a circular plate structure with two sets of arc-shaped slots 11 symmetrically distributed on the main node seat 1. The two ends of the secondary node seat 2 are respectively connected to the two sets of arc-shaped slots 11 and can slide along the arc length direction of the arc-shaped slots 11. The two sets of first support arms 3 are symmetrically distributed on the main node seat 1, and are respectively located on both sides of the secondary node seat 2. The main node seat 1 is fixedly connected to one end of the first support arm 3; two sets of second support arms 4 are located at both ends of the secondary node seat 2, and their ends are fixedly connected to the secondary node seat 2. That is, the first support arm 3 and the second support arm 4 are alternately distributed around the circumference of the main node seat 1. Since the secondary node seat 2 can slide along the arc length direction of the arc groove 11, it is equivalent to the second support arm 4 being able to rotate around the center of the main node seat 1. The positioning member 5 is set in the arc groove 11 and is used to fix the position of the secondary node seat 2 on the main node seat 1, that is, to fix the position of the second support arm 4 on the main node seat 1.

[0037] During construction, the main node seat 1 is placed vertically. The top ends of a set of first support arms 3 and a set of second support arms 4 are connected to the upper column embedded parts 6 of the adjacent columns, respectively. At this time, another set of first support arms 3 and another set of second support arms 4 are located below the main node seat 1. The bottom ends of the two sets are connected to the lower column embedded parts 7 of the adjacent columns, respectively. At this time, the two sets of first support arms 3 are connected to different concrete structural columns, and the two sets of second support arms 4 are connected to different concrete structural columns. After adjusting the angles of the first support arms 3 and the second support arms 4 appropriately, the position of the second support arms 4 on the main node seat 1 is fixed using the positioning parts 5, and the concrete structural column is locked to the supporting structure between the column, thus completing the installation.

[0038] By adopting the above technical solution, the distance between the separated ends of the first support arm 3 and the second support arm 4 can be adjusted, which can be adapted to different column spacings during construction. This overcomes the problem that traditional column support structures, due to their rigid connection, cannot meet the requirements for rapid and stable column support construction in concrete structural columns with construction errors. This technical solution can improve construction efficiency and ensure construction quality.

[0039] In this embodiment, the positioning component 5 includes a double-ended bolt 51, a first nut 52, and a second nut 53. The first nut 52 and the second nut 53 are located on both sides of the plate surface of the main node seat 1, respectively. After the double-ended bolt 51 passes through the arc-shaped slot 11, the two ends are connected to the first nut 52 and the second nut 53, respectively. There are at least two sets of positioning components 5 in each arc-shaped slot 11. The two sets of positioning components 5 are located on both sides of the secondary node seat 2, respectively. When it is necessary to fix the secondary node seat 2, the double-ended bolt 51 is slid to abut against the side wall of the secondary node seat 2, and then the first nut 52 and the second nut 53 are locked, so that the first nut 52 and the second nut 53 abut against the plate surface of the main node seat 1, at which time the double-ended bolt 51 cannot move, and the secondary node seat 2 cannot move. Under normal circumstances, high-strength double-ended bolts and high-strength nuts can meet the fixing requirements of the secondary node seat 2. In extremely special cases, after tightening the first nut 52 and the second nut 53, they can be welded to the main node seat 1 to ensure the positional stability of the double-ended bolt 51, the secondary node seat 2 and the second support arm 4.

[0040] Reference Appendix Figure 4-5 The secondary node seat 2 includes a linkage plate 21 and two sets of annular sector plates 22. The linkage plate 21 connects the two sets of annular sector plates 22 and slides along the arc length direction of the arc groove 11 together with the annular sector plates 22. The linkage plate 21 and the annular sector plates 22 are located on both sides of the plate surface of the main node seat 1. The side edge of the annular sector plate 22 is provided with a first connecting wing 23, and the side edge of the linkage plate 21 is provided with a second connecting wing 24. The first connecting wing 23 has a certain angle with the plate surface of the annular sector plate 22, and the second connecting wing 24 has an angle with the plate surface of the linkage plate 21. It has a certain included angle, the size of which can be designed and configured according to actual usage requirements; the first connecting wing 23 enters the arc-shaped slot 11 from one side of the plate surface of the main node seat 1, and the second connecting wing 24 enters the arc-shaped slot 11 from the other side of the plate surface of the main node seat 1. The first connecting wing 23 and the second connecting wing 24 are fastened by bolts, and the two can slide along the arc length direction of the arc-shaped slot 11. When the two slide, they will drive the annular fan plate 22 and the linkage plate 21 to slide along the arc length direction of the arc-shaped slot 11, thereby changing the position of the second support arm 4.

[0041] More specifically, the annular sector plate 22 has a first arc surface and a second arc surface, the arc length of the first arc surface is less than the arc length of the second arc surface, and the first connecting wing 23 connects to the first arc surface.

[0042] Both the first support arm 3 and the second support arm 4 can be made of common long steel materials, such as square steel pipes or steel rods, and are welded to the main node seat 1 and the secondary node seat 2 respectively. To ensure a stable connection, it is preferable to weld the side wall of the long steel material to the plate surface of the main node seat 1 or the secondary node seat 2 to increase the welding area and improve stability. In this case, the second support arm 4 will protrude from the plate surface of the annular sector plate 22. To avoid affecting the sliding of the secondary node seat 2, this embodiment has two sets of annular sector grooves 12 on the main node seat 1. The annular sector grooves 12 are recessed from the outer edge of the main node seat 1 towards the center. The two sets of annular sector grooves 12 are located on the opposite sides of the two sets of arc-shaped groove openings 11. When the secondary node seat 2 slides, the second support arm 4 can move in the annular sector grooves 12.

[0043] In addition, to facilitate the fabrication of the workpiece and the installation of the finished product, a first connecting seat 8 and a second connecting seat 9 can be constructed at the end of the above-mentioned long steel material. The first connecting seat 8 and the main node seat 1 are located at the two ends of the first support arm 3, and the second connecting seat 9 and the secondary node seat 2 are located at the two ends of the second support arm 4. The first connecting seat 8 and the second connecting seat 9 are used to connect the embedded parts of the column.

[0044] During construction, the first connecting seat 8 and the second connecting seat 9 located at the top can be connected to the upper column embedded part 6 firstly. The connection is made by bolts, but the bolts are not tightened, so that the first connecting seat 8 and the second connecting seat 9 located at the top have rotational freedom. After the first connecting seat 8 and the second connecting seat 9 located at the bottom are connected to the lower column embedded part 7, and the positions and angles of all the first support arms 3 and the second support arms 4 are adjusted, the bolts used to connect the column embedded part and the first connecting seat 8 and the second connecting seat 9 are tightened.

[0045] Generally, column embedded parts include embedded parts and exposed parts. As the name suggests, the embedded part is located inside the concrete structural column, while the exposed part is located on the outside of the concrete structural column. They are used to connect the inter-column support structure. The embedded part and the exposed part can be integrally formed or two components fixed by welding.

[0046] Since concrete structural columns usually have a certain construction error, the upper column embedded part 6 can be constructed in one go during the construction of the concrete structural column, while the lower column embedded part 7 can only be embedded with the embedded part, and the side of the embedded part is exposed on the side wall of the concrete structural column. After the first support arm 3 and the second support arm 4 at the upper end are pre-connected, the bottom height of the first support arm 3 and the second support arm 4 at the lower end can be determined. Then, the accurate position of the exposed part of the column embedded part is determined according to its bottom height, and the exposed part is precisely welded to the side of the embedded part to ensure the construction quality of the column support structure.

[0047] The shape and structure of the first connecting seat 8, the second connecting seat 9, and the column embedded parts (including the embedded part and the exposed part) can be designed and configured according to actual needs, and no more specific limitations are made here.

[0048] Compared with the prior art, the beneficial effects of this utility model include: the distance between the separated ends of the first support arm 3 and the second support arm 4 is adjustable, which can be adapted to different column spacings during construction. This overcomes the problem that traditional column support structures, due to their rigid connection, cannot meet the requirements for rapid and stable column support construction in concrete structural columns with construction errors. After the prefabrication of this column support structure, it can quickly and effectively connect concrete structural columns, ensure the force transmission performance of the components, improve construction efficiency, and ensure construction quality.

[0049] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
