Using method of crawler-type operation platform for net rack construction

Abstract

The invention discloses a using method of a crawler-type operation platform for net rack construction. The using method comprises the following tools of a primary platform and a secondary platform on a net rack, wherein the primary platform comprises at least one movable carrying plate, the secondary platform comprises at least two supporting rods, two hooks are arranged on each supporting rod and are hooked on a web member, a foot hand rod is installed on each supporting rod, and a springboard is bound on each foot hand rod; and a constructor stands on the primary platform to build the secondary platform, then inner plate installation is performed on the secondary platform, the rear springboards are dismounted by the person binding the springboards along with the inner plate construction speed and are moved to the front in the inner plate installation process, the movable carrying plates are dragged to a next station when the construction progress exceeds the position covered by the primary platform, namely the primary platform is pushed forwards, the secondary platform is continuously pushed forwards after the primary platform is stabilized, and inner plate installation is continuously performed. The person binding the springboards performs crawler-type line production and is matched with the crawler-type line production, and the overall moving speed is high till inner plate construction is completed.

Description

technical field [0001] The invention relates to the technical field of grid roof construction. Background technique [0002] At present, in most workshops with grid steel structure, galvanized steel purlins are installed on the upper part of the grid, and profiled steel plates are composited on site. The profiled steel plate is "reverse suspended ceiling", that is, the insulation cotton and the outer roof panel are laid and fixed on the upper surface of the purlins, and the construction is completed above the roof; the inner roof panel is laid and fixed under the purlins, and the construction personnel need to stand inside the grid frame during construction construction. Generally, the length of a single inner panel is 6 meters, and it is installed along the direction of the slope water surface. The self-tapping screws are fixed under the purlins with a row spacing of 1.5 meters, and their arrangement direction is perpendicular to the direction of the slope water. During t...

Problems solved by technology

[0003] However, the floor of the construction site is affected by the construction progress, and may not be the ground after construction. Due to the limited field level conditions, it is impossible to use machinery such as wheel lifts.

For example, the minimum height difference between the upper and lower chords of the grid frame is 2.4 meters, the maximum height difference is 4.2 meters, and the average height difference is 3.5 meters. When the inner panel is laid, standing on the lower chord plane cannot directly touch the height of the inner panel. At the same time, the lower chord of the grid frame is square. Grid shape, the length of the rod is 4 meters, it is difficult to move people, it is difficult to set up scaffolding and platforms, and the safety factor is low during construction

It is also not possible to directly set up an operating platform on the lower string of the grid frame for construction. The difficulty lies in the fact that the center of the lower string ball of the grid frame is 9.2 meters above sea level, and the building area is large.
