A hoisting device for prefabricated I-beams in house construction

Abstract

The present invention relates to a hoisting device for building assembled I-beams, which includes a lifting device, a locking device and two fixing devices, and is characterized in that a locking device is installed at the lower end of the lifting device, and the left and right ends of the locking device are symmetrical A fixing device is provided, and the fixing device is installed on the lower end of the lifting device through sliding fit. The invention provides a hoisting device for prefabricated I-beams for building construction, which can solve the problem that the existing hoisting equipment usually directly hoists the prefabricated I-beam during the hoisting process. Fixing the limit of the prefabricated I-beam will easily cause the I-beam to fall off during the hoisting process, which will damage the staff and usually use ropes, wire ropes, etc. to fix the limit of the prefabricated steel structure beam and column during the hoisting process. The effect is poor, and when the I-beam is manually loaded, the process of fixing the I-beam with ropes is cumbersome, which makes the hoisting efficiency of the I-beam low.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an assembly-type I-beam hoisting device for building construction. Background technique [0002] I-shaped beams refer to rolled iron beams, steel beams or cast steel beams with I-shaped sections, and also refer to composite beams with I-shaped sections. Prefabricated I-beams are structures composed of steel materials and are one of the main types of building structures. The I-beam structure is mainly made of section steel and steel plate, etc., and its cross-section is mainly I-shaped. The components or parts of the fabricated I-beam are usually connected by welds, bolts or rivets. Because of its light building weight, energy saving and environmental protection, fast construction speed and high degree of industrialization, it is widely used in large factories, venues, super high-rises and other fields. [0003] In actual production and manufacturing, the existing ...

AI Technical Summary

Problems solved by technology

[0004] (1) When the prefabricated I-beam is hoisted by the existing hoisting equipment, the existing hoisting equipment usually directly hoists the prefabricated I-beam during the hoisting process, and the prefabricated I-beam is not hoisted during the hoisting process. Fixed limit, easy to cause the I-beam to fall off during the hoisting process, and damage the staff;

[0005] (2) When the existing prefabricated I-beam hoisting equipment is hoisting the prefabricated I-beam, the prefabricated steel structure beams and columns are usually fixed and limited by ropes and wire ropes during the hoisting process. When loading the I-beam, the process of using ropes to fix it is cumbersome, which makes the hoisting efficiency of the I-beam low
