Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a construction method for an inclined cylindrical steel structure. Background Technology

[0002] Inclined tubular steel structures are a type of cylindrical frame structure, available in both inward and outward inclination forms. They are a common structural form in architectural design, frequently used in opera houses, exhibition halls, art galleries, and other buildings. These structures offer good compressive strength and are aesthetically pleasing.

[0003] Existing construction methods for inclined cylindrical steel structures generally involve first installing steel columns and then connecting steel beams. During column installation, hoisting equipment is used for in-situ assembly at high altitude. Multiple column sections are hoisted and connected segment by segment from the ground. Because the columns may tilt inwards or outwards, temporary support structures are needed around them for restraint and fixation. The bottom of the temporary support structure rests against the ground, and the top rests against the steel column to provide support and prevent tilting and collapse. After the columns are installed, steel beams are then inserted between the column sections to connect adjacent columns, ultimately forming a complete inclined cylindrical steel structure. Only then can the temporary support structures be removed.

[0004] It is evident that the existing construction methods for inclined cylindrical steel structures require the use of temporary support structures to assist in supporting the steel columns, which increases material costs. The installation and dismantling of temporary support structures also consume time, leading to an extension of the construction period. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the existing inclined cylindrical steel structure construction method, which requires the use of temporary support structures to assist in supporting steel columns, which increases material costs, consumes labor time, and leads to an increase in construction period. Thus, the present invention provides an inclined cylindrical steel structure construction method that does not require temporary support structures during construction, reduces production costs, and shortens the construction period.

[0006] To address the aforementioned problems, this invention provides a construction method for an inclined cylindrical steel structure, comprising: constructing the first layer of beam-column structure to the top layer of beam-column structure sequentially from bottom to top, wherein the outer edge dimensions of the first layer of beam-column structure to the top layer of beam-column structure increase or decrease from the bottom layer to the top layer.

[0007] During the construction of the first-layer beam-column structure, multiple steel columns are first set at intervals along the circumference on the ground, and then steel beams are set between every two adjacent steel columns.

[0008] During the construction of the beam and column structures of the remaining floors, the steel columns in the beam and column structure of that floor are first connected to the corresponding steel columns in the beam and column structure of the next floor. Then, a steel beam is set between every two adjacent steel columns in the beam and column structure of that floor.

[0009] Optionally, the outer dimensions of the first layer beam-column structure to the top layer beam-column structure decrease uniformly from the bottom layer to the top layer.

[0010] Optionally, the outer dimensions of the first layer beam-column structure to the top layer beam-column structure increase uniformly from the bottom layer to the top layer.

[0011] Optionally, the number of steel columns in the first layer of beam-column structure is less than the number of steel columns in the remaining layers of beam-column structure.

[0012] Optionally, some of the steel columns in the second-layer beam-column structure are connected to the steel columns in the first-layer beam-column structure, and the remaining steel columns in the second-layer beam-column structure are connected to the steel beams in the first-layer beam-column structure.

[0013] Optionally, the steel columns between adjacent beam-column structures are connected by connecting assemblies.

[0014] Optionally, the connecting assembly includes: two fixing plates respectively disposed on two connected steel columns and clamping plates disposed on both sides of the two fixing plates, wherein the two clamping plates are fixedly connected to the two fixing plates.

[0015] Optionally, the connection point between the steel beam and the steel column in each layer of the beam-column structure is located below the connection point between the steel column in that layer of the beam-column structure and the steel column in the layer above.

[0016] Optionally, the steel columns in the first-layer beam-column structure are connected to embedded parts buried underground.

[0017] Optionally, the steel column is welded to the steel beam.

[0018] The present invention has the following advantages:

[0019] 1. The present invention provides a construction method for an inclined cylindrical steel structure, comprising: constructing the first layer of beam-column structure to the top layer of beam-column structure sequentially from bottom to top, wherein each layer of beam-column structure is a structure formed by connecting steel beams and steel columns. The construction of the first layer of beam-column structure differs slightly from that of the remaining layers. While the remaining layers require connection to the layers below, the first layer is the bottom layer of the entire structure and is directly grounded. Therefore, during construction of the first layer, multiple steel columns are first spaced out along the circumference on the ground, and then steel beams are installed between every two adjacent columns to connect them, forming a ring-like beam-column structure. During construction of the remaining layers, the steel columns in the current layer are first connected to the corresponding columns in the next layer, and then steel beams are installed between every two adjacent columns in that layer. Multi-layered beam-column structures are connected to form an inclined cylindrical steel structure. From bottom to top, the outer dimensions of the multi-layered beam-column structure increase or decrease, ultimately forming an outwardly or inwardly inclined cylindrical steel structure. Correspondingly, the steel columns in each layer are not straight, but rather inclined outwards or inwards. The forces exerted by the inclination of each steel column in each layer are transmitted through the steel beams on both sides, ultimately canceling each other out and forming a stable load-bearing system. Therefore, this construction method involves first setting up steel columns and then connecting them with steel beams to form a stable beam-column structure. Each layer of the beam-column structure remains stable, eliminating the need for additional auxiliary support devices during subsequent construction. This saves on the cost of manufacturing and installing auxiliary support devices, as well as the time required for their installation and removal, thus shortening the construction period and accelerating the construction progress.

[0020] 2. The inclined cylindrical steel structure construction method provided by the present invention has a smaller number of steel columns in the first layer beam-column structure than in the remaining layers beam-column structures. This allows space to be left at the first layer beam-column structure for a door to be installed, so that personnel and goods can enter and exit the inclined cylindrical steel structure.

[0021] 3. The inclined cylindrical steel structure construction method provided by this invention connects the steel columns between adjacent two-story beam-column structures through a connecting assembly. The connecting assembly includes two fixing plates respectively installed on the two steel columns and clamping plates installed on both sides of the two fixing plates. The two clamping plates are fixedly connected to the fixing plates, thereby connecting the two steel columns together. This connecting assembly has a simple structure and is convenient to construct.

[0022] 4. In the inclined cylindrical steel structure construction method provided by this invention, the connection point between the steel beam and the steel column in each layer of the beam-column structure is located below the connection point between the steel column in that layer and the steel column in the layer above. This prevents the connection point between the steel beam and the steel column in the same layer from interfering with the connection construction of the steel column in the subsequent adjacent layers.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0041] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] Example 1

[0043] like Figures 1 to 5 As shown, this is a preferred embodiment of the construction method for inclined cylindrical steel structures of the present invention. This construction method for inclined cylindrical steel structures can be used to construct inclined cylindrical steel structures, and no temporary support structure is required during the construction process, which can reduce production costs and shorten the construction period.

[0044] The aforementioned construction method for inclined cylindrical steel structures includes: constructing the first layer of beam-column structure to the top layer of beam-column structure sequentially from bottom to top. An inclined cylindrical steel structure is a steel structure with an approximate frustum shape, generally including outward-inclined and inward-inclined types. An outward-inclined cylindrical steel structure approximates an inverted frustum, with the larger opening at the top and the smaller opening at the bottom; conversely, an inward-inclined cylindrical steel structure approximates an upright frustum, with the smaller opening at the top and the larger opening at the bottom. Regardless of whether it is an inward-inclined or outward-inclined cylindrical steel structure, it consists of multiple layers of beam-column structures arranged from the ground up. Each beam-column structure is composed of multiple steel columns 11 and steel beams 12 connected together. The steel columns 11 in each layer of beam-column structure are connected to the corresponding steel columns 11 in the adjacent upper and lower layers of beam-column structures, ultimately forming the inclined cylindrical steel structure. In other words, a completed steel column from the ground to the top of an inclined cylindrical steel structure is actually composed of multiple connected steel column segments 11, and the number of connected steel column segments 11 is equal to the number of layers of the beam-column structure. During actual construction, the number of segments of steel column 11 will vary with the inclination angle of the inclined cylindrical steel structure. The specific details can be simulated using Midas software to analyze the stress and determine the appropriate number and length of steel column 11 segments. During construction, each layer of the beam-column structure is constructed sequentially from bottom to top. In the first layer, multiple steel columns 11 are spaced out along the circumference on the ground. Then, steel beams 12 are installed between every two adjacent steel columns 11, connecting them to form an approximately ring-shaped beam-column structure. For subsequent layers, the steel columns 11 in each layer are connected to their corresponding counterparts in the next layer. Then, steel beams 12 are installed between every two adjacent steel columns 11 in that layer. The difference in construction between the first-floor beam-column structure and other floors is that the first-floor beam-column structure is the lowest level and is directly set on the ground. In contrast, the steel columns 11 in the beam-column structures of the remaining floors need to be connected to the steel columns 11 in the next floor's beam-column structure to secure them before the steel beams 12 can be installed. Because the cylindrical steel structure is inclined inwards or outwards, the steel columns 11 in each floor's beam-column structure are not straight but also inclined inwards or outwards. In existing construction techniques, the corresponding steel columns 11 in each floor's beam-column structure are connected sequentially. Only after all steel columns 11 are connected are the steel beams 12 inserted between adjacent steel columns 11. However, the inclined steel columns 11 cannot maintain stability on their own, so temporary support structures are needed during construction to assist in supporting the steel columns 11 and maintaining stability. However, in this embodiment, the construction of each layer of beam and column structure is completed sequentially. In each layer of beam and column structure, steel columns 11 are first set up, and then steel beams 12 are used to connect the steel columns 11. In this way, the tilting force of each steel column 11 will be transmitted by the steel beams 12 on both sides. Finally, the tilting forces of each steel column 11 in the ring-shaped beam and column structure will cancel each other out, forming a stable force system. Therefore, each layer of beam and column structure is stable, and no auxiliary support is needed during subsequent construction.Therefore, it can save the cost of manufacturing auxiliary support devices, and also save the construction time of installing and dismantling auxiliary support devices, thereby shortening the construction period and speeding up the construction progress.

[0045] Furthermore, in this embodiment, the outer dimensions of the first layer beam-column structure to the top layer beam-column structure decrease uniformly from the bottom to the top, meaning that the inclined cylindrical steel structure is inwardly inclined.

[0046] Specifically, in the construction method of the inclined cylindrical steel structure, the first layer of beam and column structure is constructed first, with embedded parts buried underground. Then, steel columns 11 are arranged along the circumference, and the steel columns 11 are fixedly connected to the embedded parts through connectors. For example... Figure 1 As shown, the final arrangement of the steel columns 11 does not form a complete circle, but rather leaves a gap to reserve space for a future entrance, allowing people and goods to enter and exit the building. After the steel columns 11 are installed, adjacent steel columns 11 are connected by steel beams 12, even if there is a large gap between two steel columns 11 on either side of the reserved entrance. The connection between the steel beams 12 and the steel columns 11 can be welded. Since the top of the steel column 11 needs to connect to the steel column 11 in the beam-column structure of the previous floor, to prevent interference at the connection point and inconvenience to construction, the connection point between the steel beams 12 and the steel columns 11 in each floor's beam-column structure is located below the connection point between the steel column 11 in that floor's beam-column structure and the steel column 11 in the beam-column structure of the previous floor. After the connection between the steel beams 12 and the steel columns 11 is completed, as shown... Figure 2 As shown, an approximately ring-shaped beam-column structure is formed, and this beam-column structure itself can be stably set on the ground.

[0047] Since the remaining beam and column structures no longer require space for the installation of a main entrance, the number of steel columns 11 in the first-floor beam and column structure will be less than the number of steel columns 11 in the remaining beam and column structures.

[0048] In other embodiments, the first-layer beam-column structure of the inclined cylindrical steel structure may also not require specially reserved space for doors. For example, the inclined cylindrical steel structure may have small doors with limited space between adjacent steel columns 11 for personnel and goods to enter and exit, and the steel columns 11 can be fully distributed around the circumference. In this way, the number of steel columns 11 in the first-layer beam-column structure is equal to the number of steel columns 11 in the remaining layers of the beam-column structure.

[0049] like Figure 3 , Figure 4The diagram shows the construction of the second-layer beam-column structure. Some steel columns 11 in the second-layer structure are connected to corresponding steel columns 11 in the first-layer structure, with a one-to-one correspondence. The remaining steel columns 11 in the second-layer structure are connected to corresponding steel beams 12 in the first-layer structure. Since space was reserved for a doorway in the first-layer structure, no steel columns 11 were installed at the doorway location, but steel beams 12 were installed. Therefore, the steel columns 11 in the second-layer structure corresponding to the doorway locations in the first-layer structure are directly mounted on the steel beams 12 of the first-layer structure. Thus, the number of steel columns 11 in the second-layer structure is greater than the number of steel columns 11 in the first-layer structure. After the steel columns 11 in the second-layer structure are installed, steel beams 12 are also installed between every two adjacent steel columns 11, ultimately forming a ring-shaped second-layer beam-column structure. The second-layer beam-column structure is similar in appearance to the first-layer structure, except that its outer dimensions are slightly smaller.

[0050] Furthermore, the steel columns 11 between adjacent beam-column structures are connected by connecting assemblies. For example... Figure 6 As shown, four sets of connecting components are arranged around the steel columns 11 on both sides that are connected.

[0051] Specifically, the connecting components include: two fixing plates 31 respectively disposed on the two connected steel columns 11, and clamping plates 32 disposed on both sides of the two fixing plates 31, such as... Figure 7 As shown, the fixing plate 31 is set at the end of the steel column 11, and the setting method can be welding. The fixing plates 31 on the two steel columns 11 are positioned correspondingly, and then two clamping plates 32 are set on both sides of the two fixing plates 31. The length of the clamping plates 32 is approximately equal to the length of the two fixing plates 31. Then, the two clamping plates 32 and the fixing plates 31 can be connected by bolts and nuts, so that the two steel columns 11 can be connected.

[0052] Of course, in other embodiments, the number of connecting components can also be three, five, six, etc.

[0053] The construction steps from the third-floor beam-column structure to the top-floor beam-column structure are the same: connect the steel columns 11 in each floor to the corresponding steel columns 11 in the next floor beam-column structure, using connecting components. Then, install steel beams 12 between adjacent steel columns 11 to form a complete beam-column structure. Complete the construction of the beam-column structure from bottom to top.

[0054] Furthermore, in this embodiment, the steel columns 11 in the top-level beam-column structure are not all equal, such as... Figure 5 As shown, the top surface of the final inclined cylindrical steel structure is not flat, but rather an inclined surface with one side higher than the other.

[0055] Example 2

[0056] like Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the steel columns 11 in the top beam-column structure are completely equal, and the top surface of the final inclined cylindrical steel structure is flush. The construction method is the same as that described in Embodiment 1, so it will not be repeated here.

[0057] Example 3

[0058] The difference between this embodiment and embodiment two is that in this embodiment, the outer edge dimensions of the first layer beam-column structure to the top layer beam-column structure increase uniformly from the bottom layer to the top layer, and the final inclined cylindrical steel structure is the same as the inverted shape of the inclined cylindrical steel structure formed in embodiment two.

[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
