[0042] As a preferred implementation manner, a connecting member 6 is connected between the upper ends of the diagonal columns 21 on the adjacent sides of two adjacent support cylinders 2.

[0044] Preferably, the truss is a planar truss. Among them, the outer diameter dimension of the cantilever member 3 gradually decreases from the first end to the second end.

[0045] The viewing platform includes an annular truss 51 and a platform board.

[0046] The annular truss 51 is connected between the second ends of the cantilever members 3 on the adjacent sides of two adjacent support cylinders 2. The platform board is laid on the annular truss 51.

[0047] The present invention provides a construction method for an inverted conical space grid support steel structure, including the following steps:

[0048] S1. Install a plurality of stiff columns 1. The plurality of stiff columns 1 are arranged in a ring to form a tube foundation, and the plurality of tube foundations are arranged at intervals in an arc shape.

[0049] S2. Connect the lower ends of the diagonal columns 21 to the upper ends of the stiff columns 1. The upper ends of the diagonal columns 21 are arranged obliquely upward towards the outside of the plurality of diagonal columns 21.

[0050] S3. Connect at least two circumferential connectors 22 to multiple inclined columns 21 to form a support cylinder 2;

[0052] S5. Connect an arc-shaped connector 4 to the second ends of the cantilever members 3 on the outer sides of multiple support cylinders 2.

[0053] S6. Set up an observation deck between the upper ends of two adjacent support cylinders 2, and connect the cantilever members 3 on the adjacent sides of the two adjacent support cylinders 2 to the observation deck.

[0054] The inverted conical space grid supported steel structure of the present invention is mainly applied to the design and construction of steel structure projects, can effectively expand the upper space of the building and make the building beautiful. At the same time, by adopting the multi-stage lattice support technology, the construction and installation of this type of steel structure can be realized.

[0055] The lower part of the inverted conical space grid supported steel structure of the present invention occupies a relatively small area, expands upward in space to realize a large space structure in the upper part, and forms a building shape with a smaller lower part and a larger upper part. At the same time, the inverted conical space grid supported steel structure of the present invention connects multiple structures with a smaller lower part and a larger upper part at the upper part to form a structure with a larger space shape, similar to a flying saucer, which reflects the beauty of the building.

[0056] The rod-like members of the inverted conical space grid supported steel structure of the present invention are connected by trusses, which has the advantages of high structural strength, beautiful appearance and convenient construction. At the same time, this structure adopts lattice support for segmented construction, effectively solving the problem that it is not easy to construct special-shaped structures.

[0057] The stiffening column 1 of the inverted conical space grid supported steel structure of the present invention is connected to the concrete structure to realize the stability of the foundation. The stiffening column 1 is connected to multiple inclined columns 21 to realize the outward expansion of the structure in space and form an inverted conical shape. Multiple inclined columns 21 are connected to multiple circumferential connectors 22 to form a single inverted conical space grid supported cylinder 2 steel structure. Multiple outward cantilever members 3 are arranged on the outer sides of multiple support cylinders 2 to make the inverted conical support cylinder 2 better expand outward and form a large space structure in the upper part. A circular ring truss 51 is arranged between multiple outward cantilever members 3 to form a circular observation deck. Arc-shaped connectors 4 are added to the ends of multiple outward cantilever members 3 on the outer sides of the support cylinder 2 to form a circular building in terms of the appearance of the building. To strengthen the structural connection, a connecting member 6 is arranged at the end of the inclined column 21 to make multiple inverted conical space grid supported cylinder 2 steel structures form an integral whole.

[0058] The inverted conical space grid supported steel structure of the present invention has a beautiful spatial shape. Using a truss system as the main structure, it has good mechanical properties. At the same time, the use of high-strength steel can effectively save the steel consumption. A frame structure can be arranged inside and outside the inverted conical space grid supported cylinder 2 steel structure to increase the structural stability and expand the external space. The lattice support method is used for multi-segment installation of the inclined columns 21 and the cantilever members 3, which can effectively realize the construction of this type of structure.

[0059] During the construction of the inverted conical space grid supported steel structure of the present invention, anchor bolts and stiff columns 1 are installed during the construction of the cylinder foundation, and then the concrete basement top slab is poured. After the curing is completed, the construction of the upper structure is carried out.

[0060] As Figure 4 shown. Then, a multi-level lattice support is used to install the inclined columns 21, and the hoisting construction of the first-layer circumferential connecting member 22, the second-layer circumferential connecting member 22, and the third-layer circumferential connecting member 22 (triangular pipe truss) is carried out in the gap between the two inclined columns 21. After the whole is completed, an inverted conical space structure is formed.

[0061] As Figure 4 shown, a multi-level lattice support is used to install the cantilever members 3, and the connecting members 6 between the cantilever members 3, the ring truss 51, the arc-shaped connecting member 4, etc. are installed without support to form the entire inverted conical space grid supported cylinder 2 steel structure.

[0062] After the welding of the inverted conical space grid supported steel structure of the present invention is completed, the multi-level lattice support is unloaded in stages to complete the construction of this type of steel structure.

[0063] The above description is only the preferred embodiments of the present application and the description of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
