Problems solved by technology

These three methods all have the problem of high-altitude operation, that is, the installation personnel install the components at high altitude, the speed is slow, the installation quality cannot be guaranteed, and there are personnel safety problems.
In addition, the full house scaffolding method requires a large amount of scaffolding, and the cost is considerable. The sliding method of scaffolding and grid sliding method will cause the problem of asynchronous sliding and large additional internal force in the construction of large-span cylindrical reticulated shells.

Embodiment Construction

[0010] The overall lifting or jacking construction method of "mechanism → structure" is suitable for cylindrical reticulated shell structures. Considering the structural characteristics of the cylindrical reticulated shell, the problems that need to be paid attention to during the construction process and the corresponding technical measures are as follows:

[0011] 1) When the cylindrical reticulated shell becomes a mechanism, it has two degrees of freedom in vertical and span horizontal directions. However, during the construction process, the mechanism is only allowed to do one-dimensional movement in the vertical direction, and cannot move back and forth, left and right. In order to ensure the one-dimensional movement of the mechanism, each lifting or jacking point should be synchronized during the movement. In addition, technical measures such as arranging temporary cables need to be taken to ensure that the mechanism will not move in the horizontal direction.

Abstract

An integral hoisting or jacking method for construction of the cylindrical surface reticulated shell includes such steps as arranging 6 or more hoisting cables in the generatrix direction of the reticulated shell, dividing whole structure into 5 or more parts, installing each part on the ground (including rods, panel points, rafters and roof), hoisting them to the design height, and installing the remaining structures. Its advantages are high installing speed and quality, less scaffolds, and low cost.

Description

technical field [0001] The invention relates to a construction method for overall lifting or jacking of "mechanism→structure" of a cylindrical reticulated shell. Background technique [0002] At present, the common construction methods of cylindrical reticulated shells are: full house scaffolding method, scaffold sliding method and grid sliding method. All there is the problem of high-altitude operation in these three kinds of methods, promptly installer carries out the installation work of component at high altitude, and speed is slow, and installation quality can't be guaranteed, and has the safety problem of personnel. In addition, the full-house scaffolding method requires a large amount of scaffolding, and the cost is considerable. The sliding method of scaffolding and grid sliding method will cause the problem of asynchronous sliding and large additional internal force in the construction of large-span cylindrical reticulated shells. ...
