specific Embodiment approach

[0026] The preferred embodiment of the multi-point support high-altitude loose assembly method of the regular quadrangular pyramid bolt ball grid frame of the present invention is as follows:

[0027] Include steps:

[0028] A. The starting frame of the grid frame is hoisted by a small hoisting unit assembled on the ground;

[0029] B. After the starting frame is installed, the remaining parts are assembled at high altitude;

[0030] Before the step B, firstly, MIDAS is used to accept and analyze the wire formwork of the grid, find out where the deformation may be large during the assembly process, and set up supports. The supports are designed to be a structure that can adjust the elevation at any time.

[0031] In the step A, first assemble the starting frame of the net frame into 6 pieces on the ground, hoist it to the designated position on the top of the net frame with a truck crane, and weld and fix it with the supports at both ends after checking that it is correct.

...

specific Embodiment

[0044] First, carry out the grid construction simulation calculation

[0045] There is a margin when setting the support displacement in the horizontal direction to avoid deformation of the lateral support. The support in this part is a concealed structure, which cannot be seen after on-site construction, so it is not known whether there is a downward deflection phenomenon behind, so consider setting a margin.

[0046] Grid installation sequence:

[0047] The first step: (such as figure 2 ) First assemble the net frame into blocks (6 pieces in total) on the ground, and then hoist it to the designated position on the top of the net frame with a truck crane. After checking, it is welded and fixed with the supports at both ends.

[0048] The second step (such as image 3 ): Assemble upwards from the installed starting frame on the basis of the grid frame assembled in the previous step. The order is: extend a grid forward and install the upper string of the grid frame from left...

Abstract

The invention discloses a rectangular square pyramid bolt ball grid multi-point supporting high-altitude separate assembling method. A starting frame of a net rack is lifted by a small lifting unit formed by separate assembling on the ground; after the starting frame is installed, the other portions are separately assembled in the air; before high-altitude separate assembling, a net rack wire moldis subjected to acceptance analysis through MIDAS, the place where deformation is possibly large in the assembling process is found, a support is arranged at the place, and the support is designed into the structure capable of adjusting the level at any time. According to the net rack construction method adopting starting frame blocking lifting, net rack high-altitude separate assembling and multi-point supporting, the small-area and small-tonnage net rack structure installing purpose is well achieved, for the space net rack structure with the wide development prospect, the requirements for lowering the cost, improving the efficiency, and achieving high quality and high-precision positioning can be met, and the method is applicable to most small-area low-weight net rack structure systems.

Description

technical field [0001] The invention relates to a method for loose assembly of grid structures, in particular to a method for high-altitude loose assembly of multi-point support of square pyramid bolt ball grid structures. Background technique [0002] The grid structure is a grid structure of the flat grid type, which has the characteristics of both the rod system structure and the thin shell structure, with reasonable force and large coverage span. A spatial structure with broad prospects for development. The grid structure has a beautiful architectural shape, which can give designers full creative freedom in terms of architectural plane, shape and shape. [0003] Such as figure 1 As shown, the roof steel structure grid of the central hall of the core conference area B area of ​​an international exhibition center project is a square pyramid bolt ball node grid, the grid support is the lower chord multi-column point support, and the grid axis size is 108m*67.867 m, cover...
