Embodiment Construction
[0026] Attached below Figure 1-9 The technical scheme of the present invention is further described.
[0027] An assembled tire frame of a special-shaped steel pipe truss in space, comprising a bottom tire 21 and a column 22, the column is fixedly connected to the bottom tire, a horizontal beam 23 is fixedly connected to the top of the column 21, and a positioning plate 24 is arranged on the horizontal beam 23, and the positioning plate is composed of left and right Composed of two plates, a clamping plate 25 is set in the middle of the positioning plate, and the clamping plate 25 is fixed to the horizontal beam 23. The middle of the positioning plate 24 is used to clamp the truss supervisor, and the clamping plate 25 is used for the positioning of the supervisor; there are several correction supervisors on the truss supervisor For the feature points of the curve, a column is correspondingly set under each feature point, and the height of the feature point from the bottom tir...

The invention provides a space special-shaped steel pipe truss assembling bed-jig. The bed-jig comprises a bottom bed-jig body and stand columns. The stand columns are arranged according to the distance between characteristic points used for correcting main pipe curves on truss main pipes and the bottom bed-jig body. The invention further provides a space special-shaped steel pipe truss structureground assembling and mounting method. The method comprises the steps that a space special-shaped steel pipe truss practical model is established in a computer, and design for assembling the bed-jig is performed according to truss model structural characteristics; the bed-jig is assembled according to the designed bed-jig size in the computer model; space special-shaped steel pipe truss assemblingis performed on the bed-jig; after ground assembling is completed, proper lifting points are selected according to a three-dimensional model query gravity center and a mounting angle indicated by drawings, and lifting lugs hooping the main pipes are mounted in the lifting points correspondingly; and a truss is lifted up and slowly lifted in place after the in-place angle is adjusted in the air, and therefore, the special-shaped steel pipe truss structure is mounted. By means of the space special-shaped steel pipe truss assembling bed-jig and assembling and mounting method, problems of groundassembling and mounting of the space special-shaped steel pipe truss structure are solved, and assembling and mounting can be completed at a high precision.
Description
technical field [0001] The invention belongs to the technical field of super-high steel structure construction, and in particular relates to a construction operation platform capable of elevating a special-shaped truss in super-high space. Background technique [0002] When assembling on the ground, since the space special-shaped steel pipe truss structure generally involves multi-angle and multi-diameter welding, the form is relatively complicated, how to smoothly and accurately locate it has always been a problem that plagues the industry. The traditional method generally requires a lot of complicated work. The outer dimensions of the tire frame can only be determined by calculation, and the relative size of the truss and the feature points of the tire frame cannot be accurately calculated, resulting in low precision in the final assembly size of the truss; during installation, the center of gravity of the components cannot be accurately determined, resulting in incorrect s...
