Arch-shaped hoisting jig for ultralong profiled metal roof board

Abstract

The invention provides an arch-shaped hoisting jig for an ultralong profiled metal roof board. The arch-shaped hoisting jig for the ultralong profiled metal roof board comprises five frame bodies which are all formed by welding a plurality of steel pipes in a communicating mode; the positions of the steel pipes between the spaced frame bodies correspond to one another; flange connection end boards are installed at openings of the steel pipes; the flange connection end boards at the corresponding positions are connected through bolts; upper-grade lifting lug boards are arranged on the steel pipes at the top ends; lower-grade lifting lug boards are arranged on the steel pipes at the bottom ends of the hoisting jig; the upper-grade lifting lug boards are connected with upper-grade sheep-horn slide hooks; and the lower-grade lifting lug boards are connected with lower-grade sheep-horn slide hooks. Hoisting points are arranged on the above structures evenly, hoisting loads of the roof board are dispersed, the problem that the ultralong profiled metal roof board cannot be hoisted or as the ultralong profiled metal roof board is too long during hoisting, out-of-plane stiffness is not sufficient and the ultralong profiled metal roof board deforms severely or is crushed is solved effectively, and the problems of bending deformation, edge extrusion deformation, warping and the like in the vertical transportation process of the ultralong metal roof board are well solved.

Description

technical field [0001] The invention relates to the field of large-span space structure buildings, in particular to an ultra-long-pressed metal panel bow-shaped hoisting tire frame. Background technique [0002] With the development of modern industrial buildings and the wide application of steel structures and the improvement of construction technology, in the design of large-scale industrial factory buildings and public long-span roof buildings, in order to reduce the weight of the roof, color steel plates, aluminum alloys, and aluminum-magnesium are often used. Metal sheets such as manganese alloy and titanium-zinc alloy are used as roofing sheets; in order to effectively reduce the overlap of roofing sheets and increase the integrity of the roof, so as to better ensure the overall wind pressure resistance and waterproof ability of the roof, metal roofing sheets are generally Using full-length pressing and full-length installation, some methods are required to complete th...
