Embodiment 1

[0028] see now figure 1 , figure 1 It is a structural schematic diagram of the lifting tool of the embodiment of the present invention, figure 2 for figure 1 The sectional view of A-A in, image 3 for figure 1 Sectional view of B-B in middle.

[0029] The manufacturing method of the simple hoisting tool for factory roof purlins of the present invention is used for factory roof girders that have been erected successfully. It is mainly aimed at the hoisting conditions where the purlins cannot be hoisted by machinery on site and the purlins are manually hoisted. The manufacturing method of the hoisting tool includes the following steps:

[0030] a. Determine the shape and size of the spreader according to the design, and make the spreader pole 1. The spreader pole is a steel pipe, and the length of the steel pipe is 600mm;

[0031] b. Make the lifting lug, the lifting lug 2 is a rectangular steel plate, the rectangular steel plate is centered with a through hole, one side o...

Abstract

A manufacturing method of a simple hoisting tool for a factory building roof purline is characterized in that a factory building roof beam is successfully erected, and the manufacturing method comprises the following steps: a, determining the appearance and the size of the hoisting tool according to design, and manufacturing a hoisting tool vertical rod; b, manufacturing a hoisting lug, wherein the hoisting lug is a rectangular steel plate; and c, manufacturing a base, wherein during use, a groove between an upper panel and a lower panel can be clamped into an upper flange plate of the roof beam, one end of a lifting rope is bound with the purline, and the other end of the lifting rope is pulled by a constructor to convey the purline to the factory building roof purline through a fixed pulley for bolt connection or welding. The manufacturing method of the simple hoisting tool for the factory building roof purline has the advantages of being simple in device structure, convenient to manufacture, capable of being recycled and capable of saving cost.

Description

technical field [0001] The invention relates to the field of construction of industrial steel factory buildings, in particular to a method for manufacturing a simple hoisting tool for purlins on the roof of a factory building. Background technique [0002] In the installation process of large factory buildings, the installation of roof purlins will be encountered. Usually, the purlins are mostly C-shaped steel, Z-shaped steel, H-shaped steel or channel steel. The single length is long and the number is large. When constructing purlins on the roof of a factory building, it is first necessary to hoist the purlins to the beams, and then connect the purlins to the beams. The previous construction method was to use a crane to hoist the purlins one by one. Purlins that are light, small in size, and large in number are very uneconomical and uneconomical, especially for hoisting purlins with high elevations. In order to make the boom reach the corresponding height, a crane with a la...
