Description

Technical Field

[0001] The utility model relates to the technical field of modular construction of steel structures, and is particularly suitable for modular construction of a steel structure platform above a large storage tank and an integral hoisting process. Background Art

[0002] Modular steel structure construction is an emerging building structure system with a high degree of integration and has become a hot topic in current engineering research.

[0003] The traditional method of constructing the upper steel structure platform of a large storage tank is to prefabricate the steel components in the prefabrication yard, transport them to the installation site, and then hoist them to the top of the tank by a tower crane for bulk assembly. First, install the columns, which are connected to the foundation with anchor bolts; after the columns are installed, install the steel beams in turn. After the main steel structure is completed, the pipeline and electrical instrument bridge construction will be carried out. This method cannot be constructed in parallel with the steel structure platform and the storage tank, so the construction period is long and there are many high-altitude operations.

[0004] The modular construction of steel structure platform can solve the problems of long construction period and many high-altitude operations. However, modular construction, the connection between the overall hoisting column and the anchor bolt is an issue that cannot be ignored. Taking HW300X300 column as an example, each column is usually equipped with 12 anchor bolts. Assuming that the platform has 20 columns. At this time, the total number of anchor bolts will reach 240. After the hundreds of tons of steel structure platform are hoisted as a whole, it is necessary to ensure that the 240 anchor bolts are accurately inserted into the bolt holes of the steel plate. The difficulty and accuracy requirements can be imagined. Therefore, innovative docking methods are imperative. Utility Model Content

[0035] like Figure 1-4 As shown, a modular steel structure platform is constructed to quickly locate and dock columns, including: node form one and node form two;

[0036] Node type 1 is set on the platform corners and middle columns for quick positioning;

[0037] Node type 2 is set on the platform corners and center columns for quick connection.

[0038] like Figure 2-3 As shown, the node form 1 includes: a first upper column node 1 and a first lower column node 2;

[0039] The first upper column node 1 is installed above the first lower column node 2;

[0040] The first upper column node 1 includes: a reinforcing rib plate 3, a plug-in structure 4 and a docking panel 6;

[0041] The reinforcing rib plate 3 is welded to the outer side of the column flange, and there are two of them and they are symmetrically arranged, and a welding hole 5 is opened at the bottom;

[0042] The butt joint panel 6 is welded to the column and the two reinforcing rib plates 3, leaving a gap near the column flange, and the edge is aligned with the through-welding hole 5 of the reinforcing rib plate 3;

[0043] The plug tip structure 4 is connected to the bottom of the docking panel 6 .

[0044] like Figure 3 As shown, the first lower column node 2 includes: a reinforcing rib plate 3 and a butt joint panel 6;

[0045] The stiffener plate 3 and the butt joint panel 6 on the first lower column node 2 are arranged opposite to the first upper column node 1;

[0046] A docking hole 7 is formed on the docking panel 6 on the first lower column node 2 and has the same diameter as the plug-in structure 4 .

[0047] like Figure 3 As shown, the plug-in structure 4 is a truncated cone with a smaller bottom and a larger top, and is formed by connecting two cross-shaped trapezoidal steel plates and a bottom circular steel plate. The plug-in structure 4 is integrally welded to the docking panel 6 of the first upper column node 1, and a welding hole 5 is set at the end of the column web.

[0048] like Figure 2 As shown, the node form two includes a second upper column node and a second lower column node;

[0049] The column flange and web of the upper column node are provided with full penetration weld grooves 8;

[0050] The column flange and web of the second lower column node are welded to the butt plate 9 by full penetration welding. The butt plate 9 is a steel plate with tearing resistance in the thickness direction.

[0051] like Figure 3-4As shown, the butt-jointed plate 9 is a steel plate having Z-directional properties.

[0052] See also Figure 1 , Figure 1 This is a plan view of the columns of a platform and the layout of the docking nodes of the utility model. The first upper column node 1 mainly plays the role of rapid positioning. This node needs to be arranged at the corners of the platform, sudden changes in the shape, and the central column;

[0053] Since the roof of a large storage tank is generally arc-shaped, the heights of the columns on each axis are inconsistent. The lower columns of each column are set to the same height. The lower column node and the lower half of the column are connected to the concrete column pier in advance through anchor bolts. Figure 2 shown.

[0054] During the lifting and lowering process of the platform, the plug-in tip structure 4 with a small bottom and a large top is slowly inserted into the lower column docking hole 7. The diameter of the docking hole 7 is larger than the upper diameter of the plug-in tip structure 4, which improves the docking efficiency while ensuring the docking accuracy.

[0055] Other column docking node types such as Figure 4 structure.

[0056] After the lifting and docking is completed, the web and flange of the first upper column node 1 are fully penetrated and welded. The flange welding is ensured by the welding holes 5 reserved on the web. After the flange welding is completed, the web welding is carried out. The purpose of reserving the welding holes 5 on the outer side reinforcing ribs 3 of the upper and lower columns and not welding the docking panel 6 with the flange is to prevent the welds here from overlapping and causing the strength reduction of the column steel.
