Embodiment Construction

[0024] Such as image 3 , as shown in 4, a method of adjusting the sling by using the legs of the crane, the specific steps are: use the 25-ton car crane legs as power, press the protruding part of the sling through the oil cylinder of the legs, and use L100× 100 equal-sided angle steel as support pad, use The scaffolding tube is used as a mobile device for the position of the sling, so as to realize the correction of the sling.

[0025] Such as image 3 As shown, the correction process for the upwardly protruding sling is:

[0026] (1) First put the uneven slings 1 one by one on the flat concrete floor 7, and use a 25-ton truck crane to park them side by side along the slings;

[0027] (2) According to the upward protruding degree of the sling 1, put two equilateral angle steels 2 with a length of about 1m and a model of L100×100×10 under the sling 1, and the distance between the two equilateral angle steels 2 is about 70cm. (depending on the length of the bend), the sli...

Abstract

The invention relates to a method for adjusting a suspension band by utilizing supporting legs of a crane. The method comprises the specific steps: using supporting legs of an automobile crane as power, using equal leg steel as a supporting pad, using scaffold tubes as a moving device of the suspension band, and starting an oil cylinder of the supporting legs to press a convex part or a concave part of the suspension band so as to realize the correction of the suspension band. Through the simple method disclosed by the invention, the bent suspension band can be adjusted to a position meeting design requirements, and besides, a good method for flattening a spiral bar of an anchor is created.

Description

technical field [0001] The invention relates to a sling suspended from a diamond-shaped hanging basket connected to a bottom form in expressway construction, in particular to a method for correcting the straightness of the sling. Background technique [0002] The 6# bridge in the first phase of the Tehran Northern Expressway is the most critical project of the entire highway. The bridge site is located in the 9-degree earthquake area in the northern mountainous area of ​​Iran. In order to reduce the self-weight of the bridge and further improve the seismic performance of the bridge structure, multiple schemes were compared. The design adopts 3-span corrugated steel web prestressed concrete continuous girder bridge. The bridge deck is 2×13.1m wide, the clear distance between the left and right bridges is 2m, the bridge length is 319m, and the span layout is 83+153+83=319m. Box girder 0# is 8.8m high, 6.5m wide at the bottom of the beam, and cantilever jumps out 3.5m. Consi...
