Description

Technical Field

[0001] The utility model relates to the technical field of supporting structure systems, and more specifically, to a steel frame supporting tower. Background Art

[0002] Steel frame-support structure is a common structural system in industrial buildings. According to the arrangement of supporting diagonal bars, it can be divided into cross-braced steel frame, single-braced steel frame, herringbone-braced steel frame and V-braced steel frame.

[0003] Due to the layout of the process plan, the large-span preheater tower often has pipes connected to other buildings outside the building plane, such as bypass ventilation pipes, kiln pipes, etc. If the frame column is arranged in the middle of the span, the frame column will not be continuous at the pipe connection. In addition, due to the influence of the preheater pipe opening in the plane, the frame beam cannot be set on the top of the frame column in the middle of the span;

[0004] Based on the above reasons, when the large-span preheater tower adopts a single support-frame structure system, there will be a situation where the support is not continuous. At this time, the large-span preheater tower structure system preferably adopts a herringbone steel frame-support structure system.

[0005] However, when the load of process machinery and equipment is large and the single span of the building is large, the preheater tower formed by the herringbone steel frame-support structure system still has the following problems:

[0006] 1: The calculated span of the internal primary secondary beam connected to the frame beam is still large, resulting in a large cross-sectional height of the primary secondary beam and an increase in the amount of steel structure engineering. The same situation exists on every floor plane of the building. When the number of floors of the building is large, the amount of engineering increases significantly.

[0007] 2: When the span of the primary secondary beams connecting the frame beams at both ends of the frame is large and the cross-sectional height is large, the weight of a single primary secondary beam is heavy. When the building is high, the high-altitude hoisting of a single primary secondary beam requires high hoisting capacity of the on-site tower crane and is difficult to construct. The installation period of a single-layer preheater tower is about one month. Taking a 6-layer steel structure tower as an example, the installation period of the tower structure is about half a year. As the hoisting capacity of the tower crane increases, its operating cost also increases.

[0008] 3: The primary secondary beam transfers all the larger vertical loads of the floor to the herringbone braced frame structure. The herringbone braced frame structure bears both the vertical and horizontal loads of the building, resulting in a larger cross-section of the herringbone braced frame structure as a whole;

[0009] 4: Since the herringbone support can be used as the support point of the frame beam, the cross-sectional height of the frame beam is small, while the cross-sectional height of the primary beam connected to it is larger. This causes the connection node to be affected by the height of the frame beam, and the bolts are arranged densely, which cannot meet the structural requirements of the bolt spacing. At this time, increasing the cross-sectional height of the frame beam just to meet the structural arrangement of the bolts will cause a waste of the cross-sectional height of the frame beam.

[0017] In some possible implementations, the gravity column includes a tube body, a connection assembly arranged outside the tube body and corresponding to the floor plane, a connection plate, and bolts used to connect the connection plate and the connection assembly, and the connection plate and the primary secondary beam.

[0018] In some possible embodiments, the connecting assembly includes two groups of connecting rings that are horizontally arranged and fixedly mounted on the outside of the tube body, and a connecting plate that is arranged between the two groups of connecting rings and is respectively connected to the two groups of connecting rings; the connecting plates are arranged in a one-to-one correspondence with the primary secondary beams; and the connecting plates are connected to the connecting plates by bolts.

[0021] In some possible implementations, the floor plane also includes a secondary secondary beam that cooperates with the primary secondary beam and the frame beam to form an equipment opening.

[0022] In some possible implementations, it also includes a support component in which one end is hinged to the frame beam, and the other end is hinged to two groups of frame columns connected to the group of frame beams to form a herringbone support.

[0023] In some possible implementations, the herringbone support includes two groups of diagonal braces having the same structure and being hinged to the same group of frame beams respectively, and the two groups of diagonal braces form a herringbone structure and the other ends are connected to corresponding frame columns.

[0026] By arranging the gravity column in the middle of the frame body, the load-bearing area is large, and a large part of the vertical load is directly transferred to the lower foundation structure through the gravity column, which shares a large part of the vertical load for the steel frame beams, columns and supports, thereby reducing the cross-sectional size of the steel frame beams, columns and supports;

For example, multiple positioning columns refer to two or more positioning columns. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0035] The utility model is described in detail below.

[0036] like Figure 1-Figure 5 As shown:

[0037] A steel frame supporting tower comprises a frame body 1 and a group of gravity columns 2 located in the frame body 1 and hinged to the frame body 1;

[0038] The frame body 1 includes a plurality of groups of frame columns 11 arranged vertically, and a plurality of groups of floor planes arranged vertically and connected to the frame columns 11;

[0039] The gravity column 2 is arranged vertically and is hinged to the floor plane;

[0040] The floor plane includes a frame beam 120 whose two ends are respectively connected to two adjacent groups of frame columns 11 and enclosed to form a support frame, a primary secondary beam 121 whose one end is connected to the frame beam 120 and the other end is hinged to a gravity column 2 located in the support frame, a secondary secondary beam 122 used in conjunction with the primary secondary beam 121 and the frame beam 120 to form an equipment opening 124, a tertiary secondary beam 123, and a floor panel, wherein the tertiary secondary beam 123 is used to be arranged at a larger span of the panel to reduce the span of the floor panel and transfer the uniformly distributed load of the floor, and can be specifically configured as needed;

[0041] The secondary secondary beam 122 is mainly used to transfer the load of the equipment installed at the equipment opening 124 to the primary secondary beam 121 or the frame beam 120;

[0042] The utility model sets a gravity column 2 in the frame body 1, and hinges one end of the primary secondary beam 121 thereto. Since the gravity column 2 is located in the frame body 1, the length of the primary secondary beam 121 is shortened, thereby reducing the cross-sectional height of the primary secondary beam 121. At the same time, due to the reduction in the cross-sectional height of the primary secondary beam 121, the height difference with the frame beam 120 is reduced, so that the number of bolts at the node connecting the primary secondary beam 121 with the frame beam 120 is reduced, and the structural requirements such as the spacing of the bolts are easily met. There is no need to increase the height of the frame beam 120 to meet the structural requirements, thereby saving the engineering workload of the steel frame beam 120.

[0043] When the gravity column 2 and the primary secondary beam 121 are rigidly connected, the gravity column 2 will be allocated more horizontal force according to the rigidity due to its larger cross-sectional area, so that the cross-sectional area of ​​the gravity column 2 and the cross-sectional area of ​​the primary secondary beam 121 connected thereto increase, which is much larger than the frame beam 120 and the frame column 11. In this way, the original frame support system cannot be changed, and the rigidity distribution is unreasonable.

[0044] The utility model is hingedly connected to the gravity column 2 through the primary secondary beam 121, and the gravity column 2 only bears vertical load, mainly under compression; the gravity column 2 does not bear horizontal load as a lateral force resisting member, and does not affect the seismic performance of the original structural system.

[0045] In some possible implementations, the centers of the diagonals of the multiple groups of floor planes are on the same vertical line; the gravity column 2 is located in a circle formed in the horizontal direction with a center on the vertical line and a radius of 1m;

[0046] In the present invention, the position of the gravity column 2 in the frame body 1 is limited; it is mainly arranged in the middle area, so that the load-bearing area of ​​the gravity column 2 is large, a large part of the vertical load is directly transferred to the lower foundation structure through the gravity column 2, and a large part of the vertical load is shared, so that the size of the frame beam 120 and the frame column 11 can be reduced, and the production and processing cost can be reduced;

[0047] In some possible implementations, the gravity column 2 includes a tube body, a connection assembly disposed outside the tube body and corresponding to the floor plane 12, a connection plate 213, and bolts for connecting the connection plate 213 and the connection assembly, and the connection plate 213 and the primary secondary beam 121;

[0048] Since the gravity column 2 is hinged to the primary secondary beam 121, the gravity column 2 is only subjected to pressure, and the pipe body is set as a steel tube concrete structure, that is, a steel tube concrete column; thereby, the high compressive performance of concrete is fully utilized, and the hoop effect of the steel pipe on the concrete is utilized, so as to achieve the purpose of giving full play to the material advantages and saving construction costs, and also make the installation of the connecting ring 21 easier;

[0049] Since the gravity column has a large load-bearing area, the outer diameter of the pipe body is set to be larger than the outer diameter of the frame column 11;

[0050] In order to effectively realize the hinge connection between the pipe body and the primary secondary beam 121; the connection assembly includes two groups of connection rings 21 which are horizontally arranged and fixedly sleeved on the outside of the pipe body, and a connecting plate 212 which is arranged between the two groups of connection rings 21 and is respectively connected to the two groups of connection rings 21; the connecting plates 212 are arranged one by one with the primary secondary beam 121; the connecting plates 213 are connected to the connecting plates 212 by bolts;

[0051] The connecting plate 212 is located between two groups of horizontally arranged connecting rings 21, and its upper and lower ends are respectively connected to the two groups of connecting rings 21 close to each other; a part of the connecting plate 213 is connected to the connecting plate 212 by bolts, and the other part is connected to the primary secondary beam 121 by bolts to achieve hinged connection;

[0052] Furthermore, each set of connection plates 213 for connecting the connecting plates 212 and the primary secondary beam 121 is two sets, which are located on both sides of the primary secondary beam 121 along its length direction;

[0053] The number of the connecting plates 212 is consistent with the number of the primary secondary beams 121 , and they are arranged in a one-to-one correspondence, thereby achieving hinged cooperation between all the primary secondary beams 121 and the gravity columns 2 .

[0054] In some possible embodiments, the first-level secondary beam 121 is an H-shaped steel, including an upper flange plate, a web plate, and a lower flange plate connected in sequence from top to bottom; the web plate is connected to the connecting plate 213 by bolts; the second-level secondary beam 122 is also an H-shaped steel, and the third-level secondary beam 123 is an H-shaped steel or a channel steel.

[0055] In some possible implementations, it also includes a support assembly in which one end is hinged to the frame beam 120, and the other end is connected to the frame beam 120 and two groups of frame columns 11 are hinged to form a herringbone support;

[0056] The support assembly includes two groups of diagonal braces 3 with the same structure and respectively hinged to the same group of frame beams 120, the two groups of diagonal braces 3 form a herringbone structure and the other ends are connected to the corresponding frame columns 11;

[0057] The herringbone support formed not only ensures the stability of the structure, but also bears the vertical and horizontal loads of the building together; it makes the structure more stable and reliable, and improves the earthquake resistance and load-bearing capacity of the building; in addition, it also has many characteristics such as easy construction, short construction period, and detachability;

[0058] Furthermore, the frame column 11 is a steel pipe column with a circular cross section, and the frame beam 120 is an H-shaped steel, and the two are rigidly connected; when the equipment load or horizontal load borne by the frame column is large, the frame column 11 can be a steel tube concrete column.

[0059] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
