Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a three-dimensional iterative assembly method of a spherical shell connected with all bolts. Background Art

[0002] Spherical shell structures are widely used in scientific research and landscape. Due to scientific research or aesthetic needs, some spherical shell structures are not allowed to be welded and can only be connected by full bolts, which places high demands on the processing accuracy of components. Pre-assembly in the factory is the key to ensuring component accuracy and full bolt connection. With the increase in the size of the spherical shell and the complexity of the structure, the site requirements required by the traditional assembly process are difficult to meet. Summary of the invention

[0003] The present invention mainly solves the deficiencies in the prior art and provides a three-dimensional iterative assembly method for a spherical shell connected with all bolts, which has the advantages of convenient assembly, space saving and guaranteed accuracy. It solves the problem of how to achieve full-circle closed-loop assembly of the overall spherical shell. It reduces the requirements for site conditions for pre-assembly and realizes efficient, accurate and flexible spherical shell structure construction.

[0004] The above technical problems of the present invention are mainly solved by the following technical solutions: A three-dimensional iterative assembly method for a fully bolted spherical shell includes the following steps: Step 1: Divide the spherical shell into several planar steel frames along the meridian of the spherical shell.

[0005] Step 2: Lay out the positioning line of the flat steel frame at a 1:1 ratio on the ground, assemble the flat steel frame, and screw in the mounting bolts.

[0006] Step 3: Lay out the plane projection of the three steel frames corresponding to their spatial positions at a 1:1 ratio on another ground, and erect the positioning frame for assembly based on the plane projection.

[0007] Step 4: Complete the pre-assembly of three steel frames on the positioning frame.

[0008] Step 5: After the pre-assembly of the three steel frames is completed, dismantle the first steel frame and move the following flat steel frames forward one by one.

[0009] Step 6: Assemble the flat steel frame according to step 2.

[0010] Step 7: Pre-assemble the newly assembled flat steel frame at the position of the original last steel frame on the assembly frame.

[0011] Step 8: According to the process from step 5 to step 7, complete the pre-assembly of the remaining steel frames to realize the full-circle closed-loop pre-assembly of the fully bolted spherical shell structure.

[0012] Preferably, the initial number of planar steel frames is 3, and the assembly of the first steel frame, the second steel frame and the third steel frame is completed first.

[0013] Preferably, when pre-assembly reaches the last steel frame, the first steel frame is placed at the position of the third steel frame in the fourth step to complete the full-circle closed-loop pre-assembly.

[0014] The present invention can achieve the following effects: The present invention provides a three-dimensional iterative assembly method for a spherical shell connected with all bolts. Compared with the prior art, the method has the advantages of convenient assembly, space saving and guaranteed accuracy. The method solves the problem of how to realize a closed-loop assembly of the entire spherical shell. The method of combining plane assembly with three-dimensional assembly and the ground and low-altitude assembly methods are adopted to solve the restrictions of the assembly site and improve the assembly efficiency. The three-dimensional assembly of three steel frames is adopted, and the "two-one iteration" method is used to realize the closed-loop assembly of the entire spherical shell, which solves the problems of high requirements and difficulty of the assembly site and ensures the overall assembly accuracy.
