Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an auxiliary tooling for cable structure construction. Background Art

[0002] The roof design of a large stadium typically combines steel and cable structures, such as a semi-rigid spoke-type tensioned structure. Its structure primarily comprises: grandstand steel columns, a facade grid, a roof grid, inner and outer ring beams, and a cable structure. The cable structure primarily consists of 72 radial cables (80mm diameter), a central ring cable composed of four stay cables (110mm diameter), and diagonal stay cables (55mm diameter), forming a tensioned structure. The steel roof grid supports the upper radial beams and annular compression rings through fly columns and braces beneath the grid, thereby increasing the vertical stiffness of the roof structure.

[0003] In common fly column installation projects in the prior art, the fly columns are often integrated with the struts. However, for some fly column structures in cable structures, if the fly columns are installed with a force-bearing system, they are subject to both tension and compression. In this case, the fly columns are typically installed in sections, with upper and lower sections. Direct installation in such projects would not meet the required force requirements for the fly columns and would also fail to meet the designed installation requirements. Therefore, there is an urgent need to design an auxiliary tool for cable structure construction that can complete the installation of two fly columns and address the force-bearing system installation issues.

[0019] The technical solution of the present utility model is further described below through the accompanying drawings and embodiments.

[0020] The project of this embodiment is aimed at the installation and construction of flying columns in the cable-supported grid structure of the Maoming Olympic Sports Center project. A first sealed cable 11 with a diameter of 80 mm and a second sealed cable 12 with a diameter of 110 mm are installed on the cable clamp 10. An ear plate 13 is installed on the top of the cable clamp 10, and the support rod 6 is installed on the ear plate 13.

[0021] Combine Figures 1 to 4 This embodiment provides an auxiliary tooling for cable structure construction, including a tooling bracket, a sleeve 2 and a supplementary liner 3. The tooling bracket is arranged on the fly column, and the fly column is divided into a lower fly column 4 and an upper fly column 5. The lower fly column 4 is connected to the plug plate 7 on the support rod 6 through a pin shaft. The lower end of the sleeve 2 is arranged in the inner hole of the lower fly column 4, and the lower part of the upper fly column 5 is sleeved on the outer side of the upper end of the sleeve 2. The supplementary liner 3 is arranged between the lower fly column 4 and the upper fly column 5.

[0022] In this embodiment, the tooling corbel is divided into a first corbel 8 and a second corbel 9. The first corbel 8 is welded to the outer wall of the lower fly column 4, and the second corbel 9 is welded to the outer wall of the upper fly column 5. The first corbel 8 and the second corbel 9 are located on the same plane.

[0023] Preferably, during supporting, a jack 1 is provided between the first corbel 8 and the second corbel 9 , the fixed end of the jack 1 is installed on the top of the first corbel 8 , and the output end of the jack 1 is connected to the bottom of the second corbel 9 .

[0024] Preferably, during tensioning, a jack 1 is installed on the top of the second corbel 9 , the fixed end of the jack 1 is located on the top of the second corbel 9 , and the output end of the jack 1 is connected to the first corbel 8 through a steel strand 14 .

[0025] In a further embodiment, the lower end of the sleeve 2 is welded to the inner hole of the upper end of the lower fly column 4 .

[0026] In a further embodiment, the supplementary liner 3 is welded between the lower fly column 4 and the upper fly column 5, the top end face of the supplementary liner 3 is fitted with the lower end face of the upper fly column 5, the bottom end face of the supplementary liner 3 is fitted with the upper end face of the lower fly column 4, and the outer side faces of the lower fly column 4 and the upper fly column 5 are flush with the outer side face of the supplementary liner 3.

[0027] In this embodiment, the fly column is divided into a lower fly column 4 and an upper fly column 5. The lower fly column 4 is connected to the plug plate 7 on the support rod 6 through a pin. During construction, the first step is to weld the first bracket 8 to the outer wall of the lower fly column 4. The second step is to weld the lower end of the sleeve 2 to the inner hole at the upper end of the lower fly column 4, and the second bracket 9 to the outer wall of the upper fly column 5. The third step is to weld the subsequent liner 3 in blocks between the lower fly column 4 and the upper fly column 5.

[0028] According to the solution of this embodiment, when installing the upper fly column, due to the presence of the sleeve 2, the upper fly column can be displaced along the sleeve 2 under the action of the jack. When the target position is reached, the subsequent liner 3 is welded in blocks between the two fly columns. At this time, the fly column installation is completed.

[0029] Compared with the conventional fly column installation, the support rod and the fly column node are separated, and the jacking tooling bracket is added. This can meet the force of the fly column during the installation of the fly column, and at the same time better meet the design installation requirements. It has the advantages of simple structure, convenient connection and low cost.
