[0032] See also Figure 1-6 The embodiment of the present application provides a circular stadium steel structure sliding construction method, which is mainly used to install a steel structure composed of a plurality of steel pipe trusses 11 on a circular stadium 10.

[0033] Embodiment 1

[0034] A circular stadium steel structure sliding construction method comprises the following steps:

[0035] Step 1: See Figure 1 At least one circular track is installed on the circular venue 10, and the circular track is arranged concentrically with the circular venue 10 and also concentrically with the steel structure composed of a plurality of steel pipe trusses 11.

[0036] Step 2: See Figure 2 , a lifting device 30 is used to lift the first steel tube truss 11 onto the circular track at the lifting station, and the steel tube truss 11 is slidably matched with the circular track.

[0037] Step 3: See Figure 3 , move the first steel tube truss 11 along the circular track until it completely leaves the hoisting station to make room for the next steel tube truss 11 to be hoisted.

[0038] Step 4: See Figure 4 , the lifting equipment 30 is used again to lift the second steel tube truss 11 to the annular track at the lifting station, and the steel tube truss 11 is slidably matched with the annular track.

[0039] Step 5: Fix the second steel tube truss 11 to the first steel tube truss 11 through a connector, and move it along the circular track until it completely leaves the lifting station to make room for the next steel tube truss 11 to be lifted.

[0040] Step 6: See Figure 6 , repeat the above steps 2 to 5, and so on, until all the steel tube trusses 11 are installed.

[0041] The above-mentioned circular stadium steel structure sliding construction method sets up the circular track in advance. It only needs the lifting equipment 30 to lift the steel pipe truss 11 to the circular track at the lifting station, and then move the steel pipe truss 11 to the installation position by the circular track. The lifting equipment 30 does not need to be moved during the entire installation process, which effectively solves the problem of requiring 30 lifting equipments to transfer and lift in multiple places and the difficulty of lifting in the traditional installation process; and the lifting is simple, efficient, short in construction period and high in safety.

[0042] Embodiment 2

[0043] A circular stadium steel structure sliding construction method comprises the following steps:

[0044] Step 1: See Figure 1 At least one circular track is installed on the circular venue 10, and the circular track is arranged concentrically with the circular venue 10 and also concentrically with the steel structure composed of a plurality of steel pipe trusses 11.

[0045] Step 2: See Figure 2 , a lifting device 30 is used to lift the first steel tube truss 11 onto the circular track at the lifting station, and the steel tube truss 11 is slidably matched with the circular track.

[0046] Step 3: Move the first steel tube truss 11 along the circular track to the installation position. It should be noted that the installation position of the first steel tube truss 11 refers to the fixed position on the circular stadium 10 when it constitutes the steel structure.

[0047] Step 4: Repeat the above step 3 until all the steel tube trusses 11 are hoisted. Figure 6 .

[0048] Step 5: Finally, all the steel tube trusses 11 are fixedly connected by connecting pieces.

[0049] The above circular stadium steel structure sliding construction method sets up a circular track in advance, and only requires the lifting equipment 30 to lift the steel tube truss 11 to the circular track at the lifting station, and then move the steel tube truss 11 to the installation position by the circular track. The lifting equipment 30 does not need to be moved during the entire installation process, which well solves the problem of the need for lifting equipment 30 to transfer and lift in multiple places and the difficulty of lifting in the traditional installation process; and the lifting is simple, efficient, short in construction period, and highly safe. Moreover, by lifting a steel tube truss 11, moving a steel tube truss 11 to the installation position, and finally performing the overall fixed connection, it is relatively labor-saving and prevents the difficulty of moving due to too many connections of the steel tube truss 11.

[0050] Embodiment 3

[0051] Step 1: See Figure 1 At least one circular track is installed on the circular venue 10, and the circular track is arranged concentrically with the circular venue 10 and also concentrically with the steel structure composed of a plurality of steel pipe trusses 11.

[0052] Step 2: See Figure 2 , a lifting device 30 is used to lift the first steel tube truss 11 onto the circular track at the lifting station, and the steel tube truss 11 is slidably matched with the circular track.

[0053] Step 3: See Figure 3 , move the first steel tube truss 11 along the circular track until it completely leaves the hoisting station to make room for the next steel tube truss 11 to be hoisted.

[0054] Step 4: See Figure 4 , the lifting equipment 30 is used again to sequentially lift the second and third steel pipe trusses 11 onto the circular track at the lifting station.

[0055] Step 5: See Figure 5 The first, second and third steel tube trusses 11 are first fixedly connected by connecting pieces, and then moved to the installation position along the circular track. It should be noted that the installation position of the steel tube trusses 11 refers to the fixed position on the circular stadium 10 when the steel structure is formed.

[0056] Step 6: See Figure 6 Repeat the above steps 2 to 5, and so on, until all the steel tube trusses 11 are installed, and finally all the steel tube trusses 11 are fixedly connected into an integral steel structure.

[0057] The above circular stadium steel structure sliding construction method sets up a circular track in advance, and only needs the lifting equipment 30 to lift the steel tube truss 11 to the circular track at the lifting station, and then move the steel tube truss 11 to the installation position by the circular track. The lifting equipment 30 does not need to be moved during the entire installation process, which solves the problem of the traditional installation process requiring lifting equipment 30 to transfer and lift in multiple places, and the difficulty of lifting and lifting; and the lifting is simple, efficient, short in construction period, and highly safe. In addition, connecting the steel tube trusses 11 in groups of three first and then moving them to the installation position can prevent the difficulty of moving due to too many connections, while also achieving installation efficiency.

[0058] Based on any of the above embodiments, in some specific implementations, three circular tracks are installed on the circular venue 10. The three circular tracks are arranged concentrically with the circular venue 10. The three circular tracks are arranged from outside to inside and from low to high. Figure 1 The three annular tracks support the upper, middle and lower parts of the steel tube truss 11 respectively, so that it can move stably without deformation.

[0059] It is understandable that setting three paths is the most preferred here, and it is understandable that more than two paths can achieve the above effect.

[0060] In a further specific embodiment, each steel tube truss 11 corresponds to three circular tracks, and is divided into three independent parts, namely, the lower, middle and upper parts, which are sequentially hoisted by the lifting equipment 30 until they are slidably matched with the three circular tracks, and then the three independent parts are fixedly connected into a whole. Dividing each larger and heavier steel tube truss 11 into three smaller and lighter parts, and hoisting them in three times, can reduce the pressure of the hoisting equipment 30, make the hoisting more stable, reduce the requirements for the hoisting equipment 30, and facilitate the operation and reduce the cost.

[0061] Specifically, the three circular tracks are respectively a first circular track 21, a second circular track 22 and a third circular track 23, and the first circular track 21, the second circular track 22 and the third circular track 23 are arranged from outside to inside and from low to high; Figure 1 As shown, the first annular track 21 and the second annular track 22 are fixedly mounted on the circular stadium 10, and the third annular track 23 is supported inside the circular stadium 10 by an independent annular support system to ensure overall stability.

[0062] The annular support system includes lattice columns in an annular array, and the third annular track 23 is fixedly mounted on the lattice columns; and circular tube single column supports are arranged between the lattice columns to further increase the overall stability.

[0063] Based on any of the above embodiments, in some specific implementations, multiple groups of jacking devices are evenly installed at the annular track, and the jacking devices are used to push the steel tube truss 11 to move along the annular track within their jacking ranges, and the jacking ranges of adjacent jacking devices overlap. The steel tube truss 11 is pushed into place in a relay form by multiple groups of jacking devices.

[0064] It is understandable that the jacking device commonly uses a hydraulic cylinder, and the jacking range refers to the maximum telescopic range of the hydraulic cylinder.

[0065] It should be noted that the hydraulic cylinder can use a common hydraulic cylinder system in the construction field, mainly including a hydraulic pump source system and a synchronous control system, etc. The synchronous control system controls the angular velocity of each jacking point of the steel tube truss 11 on the first circular track 21, the second circular track 22 and the third circular track 23, respectively, so that they can run synchronously and slide in an orderly manner. The existing hydraulic cylinder system is used and will not be described in detail.

[0066] In summary, the circular stadium steel structure sliding construction method provided by this application has the following technical effects:

[0067] 1. Complex structural parts such as steel structural members (steel tube trusses 11, grids) of different sizes, specifications and weights can be slid to the designated installation positions through the circular track, and the construction method is simple.

[0068] 2. The rotating and sliding ring track design is adopted to reduce the displacement of lifting equipment by more than 30 times, reduce the basic conditions required for the lifting equipment to occupy 30 positions, save space, shorten the construction period, greatly improve construction efficiency, save costs, and shorten the construction period.

[0069] 3. The rotating and sliding ring track design greatly reduces the aerial assembly work. At the same time, other different components (purlins, curtain wall embedded parts, walkways, pipe supports) can be installed to the steel tube truss 11 at the same time without considering deformation and weight requirements.

[0070] 4. The construction process is simple and repeated construction is conducive to improving work efficiency.

[0071] 5. Reduce workers' high-altitude operations, greatly reduce safety risks, and improve social benefits;

[0072] 6. The construction period is shortened, the construction period is guaranteed, and it can be completed and put into use ahead of schedule, which has benefits for people's livelihood.

[0073] 7. Reduce the difficulty of construction workers' operations, saving time and effort.
