The cable bar structure comprises radial cables 50, circumferential cables 51 and V-shaped supports 52. The T-shaped component 10 comprises a top ring beam, a radial beam 20, a pressure ring beam 30 and an inner cantilever beam 60, wherein the top ring beam is connected with the outer end of the radial beam, the pressure ring beam is respectively connected with the inner end of the radial beam and the outer end of the inner cantilever beam 60, and the middle end of the pressure ring beam, the inner cantilever beam 60 and the outer end of the radial beam are respectively connected with a cable rod structure and form a triangle on two same planes.
Specifically, step S1 is executed to perform component segmentation on the intermediate pressure ring spoke type tensioning structure, so that the intermediate pressure ring spoke type tensioning structure is formed by enclosing a plurality of T-shaped components 10. By adopting the segmentation method, the high-altitude welding at the butt joint of the radial beam 20 and the pressure ring beam 30 can be avoided, the influence of welding shrinkage on the installation precision is further avoided, and the overall installation precision is effectively controlled.
Then, step S2 is executed, and with reference to fig. 5, the T-shaped member 10 is assembled on the jig frame support 70, where the T-shaped member 10 includes the radial beams 20 and the compression ring beam 30 perpendicular to each other. In this embodiment, the T-shaped member 10 has a large size, and the length thereof exceeds the conventional transportation size for transportation, so that it is required to be segmented to the site, and the assembly jig frame is arranged on the site to be assembled and then installed. In order to ensure the installation accuracy of the combined component, the radial beam 20 and the compression ring beam 30 need to be transported to the site and then expanded and assembled, the T-shaped component 10 is positioned and welded on the ground jig frame support 70, and after the acceptance is qualified, the T-shaped component 10 is hoisted to the designed position integrally. In this embodiment, the construction site is provided with a plurality of assembling jig frames according to the installation progress, and each assembling jig frame comprises 6 jig frame supports 70.
The jig assembly method is suitable for assembling the T-shaped components with different sizes in a construction site, and only the position of the jig support 70 needs to be moved, so that the jig recycling efficiency is high, the assembly speed of the combined components is greatly improved, the bearing capacity of the jig support is large, the flatness is high, the operation is convenient, and the assembly requirement of the heavy combined components with large sections can be met.
The step of assembling the T-shaped member 10 specifically includes:

After the step S1 is completed, the step S21 is executed to convert the aerial installation coordinates of the T-shaped member 10 into jig assembly coordinates, determine the coordinates of the key points of the T-shaped member 10, and control the T-shaped member through a three-dimensional coordinate system, thereby improving the assembly accuracy of the T-shaped member 10.
Then, step S2 is executed to assemble the T-shaped member 10 into three segments, and a jig support 70 is disposed under each segment.
Finally, step S3 is executed to pre-unload the assembled T-shaped member 10. In this embodiment, the pre-unloading of the T-shaped member 10 specifically includes:
the jig support 70, which is located below the middle section of the tee, is removed to simulate the in-air support of the tee 10. The T-shaped member 10 is pre-unloaded by simulating the laying state of the T-shaped member 10 in the air, so that the deformation of the T-shaped member 10 is stable, and the installation precision of the T-shaped member is improved.
Further, with reference to fig. 6, an end ear plate 80 is preset at one end of the radial beam 20 away from the pressure ring beam 30, and after the T-shaped member 10 is pre-unloaded, the method for installing the center pressure ring spoke type tension structure further includes:
a middle lug plate 81 is mounted at one end of the radial beam 20 near the compression ring beam 30.
In this embodiment, the end ear plate 80 and the middle ear plate 81 are used for connecting the radial cable 50 and the V-shaped support 52, respectively, and the length of the radial cable 50 is fixed, so that the middle ear plate 81 needs to be positioned, and the installation accuracy is improved.
In this embodiment, the step of installing the middle ear plate 81 at the end of the radial beam 20 close to the ring compression beam 30 specifically includes:
the middle ear plate 81 is positioned according to the pin hole distance L between the pin hole on the end ear plate 80 and the pin hole on the middle ear plate 81.
Specifically, when the middle ear plate 81 is positioned according to the pin hole distance L, the temperature deformation is calculated according to the actual temperature and the theoretical temperature, and the pin hole distance L is compensated according to the temperature deformation. For example, the radial beam 20 and the pin hole distance L are deepened according to a zero stress state, the theoretical temperature is 20 ℃ when calculation is performed, and temperature compensation needs to be considered because the field assembly is performed outdoors in winter and the actual temperature is greatly different from the theoretical temperature.
According to the temperature deformation formula: and the temperature deformation coefficient is alpha, 12 multiplied by 10 < -6 > is taken as a steel structure, L is the pin hole distance L, and delta t is the temperature difference. According to the calculation result, when the outdoor actual temperature is 5 ℃, the theoretical distance L of the pin hole is reduced by 3.6-6.2 mm. During construction site assembly, temperature is measured actually every day, the pin hole distance L is calculated, and the middle ear plate 81 is positioned.
Next, step S3 is executed, where a sway brace 40 and a first temporary support are installed at one end of the radial beam 20 away from the pressure ring beam 30, and a second temporary support is installed at both ends of the pressure ring beam 30. The mounting stability of the T-shaped member 10 is ensured by supporting in a three-point supporting manner. In this embodiment, the sway column 40 is not required to be arranged under all the T-shaped members 10, and in the case that the overall structural stability is satisfied, part of the sway column 40 may be replaced with a temporary support, such as a steel pipe, which may be removed after the construction of the center-pressure ring spoke type tension structure is completed.
Then, step S4 is executed, all the T-shaped members 10 are hoisted in sequence and assembled into an annular structure, so that the T-shaped members 10 rest on the first temporary support and the second temporary support.
Further, the step of sequentially hoisting all the T-shaped members 10 and assembling the T-shaped members into an annular structure specifically includes:
and selecting a certain point on the middle compression ring spoke type tensioning structure as an original point, and sequentially assembling the T-shaped components 10 clockwise and anticlockwise by taking the original point as a center.
In this embodiment, the midpoint on the long side of the ellipse is selected as the origin, and two lines are opened clockwise and counterclockwise to realize the folding of the middle-set compression ring spoke type tensioning structure. Of course, the assembly can be performed in a clockwise or counterclockwise manner, or in other manners, which is not limited in this application.
Referring to fig. 7, when the T-shaped member 10 is hoisted, at least four hoisting points are arranged on the radial beam 20 along the axial direction of the radial beam 20 according to the eccentricity of the T-shaped member 10, and one hoisting point is arranged at each of two ends of the compression ring beam 30. After the hoisting condition analysis of the single T-shaped member 10, the gravity center position of the member is not at the center position of the radial beam 20, and the member is eccentric. If the traditional multi-point hoisting rigging configuration is adopted, the component balancing difficulty and the safety risk are high, large stress and local deformation can be generated at the welding lifting lug, and large potential safety hazards and installation errors can be generated when the compression ring beam 30 in the axial compression mode is installed. Therefore, in the embodiment, 4 lifting points are arranged on the radial beam 20, 2 steel wires are used for being communicated with each other, the left and the right of the pressure ring beam 30 are respectively provided with one lifting point, and the 2 steel wires are transversely provided with the immortal gourd 90 for leveling the eccentric combined member, so that the stability, the safety and the installation accuracy of the combined member in the hoisting process are ensured. By the hoisting method, the problems that the compression ring beam 30 in the axis compression mode generates large stress and local deformation at the position of the welding lifting lug can be well solved, the component installation precision is greatly improved, and the actual installation and theoretical coordinates of the combined component are controlled within +/-5 mm.
In this embodiment, the pressure ring beams 30 of two adjacent T-shaped members 10 are flange-connected.
Step S5 is executed, the radial cables 50, the hoop cables 51, the V-shaped supports 52, and the inner cantilever beams 60 are installed under the T-shaped members 10, and the top ring beam and the hoop secondary members between two adjacent T-shaped members 10 are supplemented, so as to form a stable structural system. In this embodiment, the top ring beam and the annular secondary member between two adjacent T-shaped members 10 can be simultaneously assembled with the T-shaped members 10, and after the T-shaped members 10 are folded, the radial cables 50, the annular cables 51, the V-shaped supports 52, and the inner cantilever beam 60 are installed below the T-shaped members 10.
Finally, step S6 is executed, to form a stable structural system, the first temporary support and the second temporary support are unloaded, and the sway brace 40 is welded to the radial beam 20. The swinging columns 40 serve as permanent supports to support the middle pressure ring spoke type tensioning structure.
