Problems solved by technology

[0002] For long-span steel girder steel structures, the traditional construction method is: use multiple large-scale machinery and equipment to coordinate hoisting construction methods. This construction method requires a wide site, and multiple large-scale machinery and equipment cooperate at the same time, and the cost is relatively high.

Embodiment Construction

[0015] Such as figure 1 As shown, the present invention is a construction method for overall lifting of large-span steel girder pulling rods, comprising the following steps:

[0016] (1) To make a simple pole pulling device, first select a steel plate base 1, weld a vertical pole 2 longitudinally on the steel plate base 1, weld the rib plate 3 at the connection part of the steel plate base 1 and the vertical pole 2, and weld the top of the vertical pole 2 A beam 4, a lifting lug 5 is welded at both ends of the beam 4, and two diagonal braces 6 are welded between the vertical bar 2 and the beam 4; the beam 4 is made of 32a I-beam; the lifting lug 5 is made of 200×150×30mm It is made of steel plate with a hole in the center; the vertical rod is made of round steel pipe of 168×8mm; the diagonal brace 6 is made of round steel pipe of 76×4mm; (2) Set anchor bolts on the concrete beams or columns on both sides of the shaped steel beams, and install the simple pull-out rods on the a...

Abstract

The invention discloses a construction method for integrally lifting a large-span type steel beam pulling bar and particularly discloses a construction method for splicing and welding to manufacture a simple pulling bar in site by using a large-span type steel beam aiming at the characteristics of large span and complex modelling for integral lifting, aiming at overcoming the defects of wide required field, large-size mechanical equipment lifting and high cost of the traditional construction method. The invention provides a novel construction method for a project with a narrow field and a complex peripheral environment. When the construction of a large-span steel structure type steel beam is carried out by adopting the method, a profile steel beam is processed in segments as required in a factory, all segments are spliced and welded in site, therefore overhead working is prevented, welding quality is easy to ensure, site requirement for lifting by adopting multiple large-size mechanical equipment is prevented, project cost is reduced, and a construction period is shortened.

Description

technical field [0001] The invention relates to a construction method for overall lifting of a large-span steel girder pulling rod, which belongs to the field of construction. Background technique [0002] For long-span steel girder steel structures, the traditional construction method is: use multiple large-scale mechanical equipment to coordinate hoisting construction methods. This construction method requires a wide site, and multiple large-scale mechanical equipment cooperates at the same time, and the cost is relatively high. Contents of the invention [0003] Aiming at the deficiencies in the existing technology, the technical problem to be solved by the present invention is to provide a construction method for the overall lifting of large-span steel beam pullers, which avoids high-altitude operations, easily guarantees welding quality, and avoids the use of multiple large-scale mechanical equipment The site requirements for hoisting reduce the engineering cost and s...
