Abstract
The invention provides a long-span steel structure corridor construction method. Support steel columns on two sides of a span are firstly installed, then transverse horizontal steel beams are hoisted, support steel beams and oblique support steel beams among the transverse horizontal steel beams are installed, a vertical horizontal steel beam and a striding horizontal draw rod are further installed between two transverse horizontal steel beams, and finally transverse steel beams required by construction are installed. The long-span steel structure corridor construction method is characterized in that auxiliary trusses are installed between the support steel beams after the support steel beams are installed, and the auxiliary trusses serve as hanging points to hoist the transverse horizontal steel beams and then dismantled after the support steel beams and the oblique support steel beams are further installed between the transverse horizontal steel beams. The long-span steel structure corridor construction method has the advantages of utilizing the auxiliary trusses to install the transverse horizontal steel beams with largest volume, adopting a spare part hoisting mode for an overall steel structure and reducing the field requirement of surrounding construction and the requirement for a crane.
Description
Technical field
The present invention relates to a kind of Construction of Steel Structure method, particularly a kind of large-span steel corridor construction method.
Background technology
Generally all be directly to lift by loop wheel machine behind the Assembling during high-altitude long-span multi-storey steel structure construction of the prior art, there is following shortcoming in this mode, and need to there be larger fabricating yard at the scene, just can finish installation.The loop wheel machine that uses on the other hand also needs to take huge place.So the communal facility that this form of construction work is not adapted in some uses is used on every side.
Summary of the invention
The objective of the invention is provides a kind of easy construction for the deficiency that solves above-mentioned technology, and it is few to take the construction plant, and uses loop wheel machine little, and mounted configuration is large-span steel corridor construction method firmly.
In order to achieve the above object, the large-span steel corridor construction method that the present invention is designed, the brace steel post of span both sides at first is installed, then lift the transverse horizontal girder steel, support steel beam and diagonal brace girder steel between the transverse horizontal girder steel then are installed, install again two between the transverse horizontal girder steel the vertical levels girder steel and stride girt, the horizontal girder steel that last installation needs, it is characterized in that after brace steel post is installed, first between two brace steel posts, auxiliary girder is installed, the lifting transverse horizontal girder steel take auxiliary girder as suspension centre is removed auxiliary girder after installing support steel beam between the transverse horizontal girder steel and diagonal brace girder steel again.The characteristics of this job practices are to utilize the transverse horizontal girder steel of auxiliary girder installation volume maximum, and whole steel work then adopts the loose mail lifting mode, have reduced the place needs of constructing on every side, have also reduced the requirement to loop wheel machine.
In order to improve the structural stability of the steel work that obtains after construction is finished, the elastic deformation that forms because of deadweight by calculating the high-altitude girder steel before the construction, when then installing during take auxiliary girder as suspension centre in when construction, adjust respectively the deformation of transverse horizontal girder steel according to result of calculation.Simultaneously described deformation according to result of calculation adjustment transverse horizontal girder steel is the position of adjusting the transverse horizontal girder steel by the pulling force cucurbit.This mode has been predicted the influence of crust deformation of girder steel when construction, directly provide pre-made allowance for girder steel deformation when construction, so that the total of constructing after finishing is stable.
The resulting large-span steel corridor construction of the present invention method, method by the loose mail lifting, and utilize and comparatively easy auxiliary girder is installed as suspension centre, the huge transverse horizontal girder steel of span is installed, and set in advance the surplus of girder steel deformation, so that in most of situation, there is horizontal connection to support between the brace steel post and exists, so that whole steel work just is under the more stable structural behavior, and finally finish whole construction when loose mail lifts.In addition, owing to can utilize auxiliary girder as suspension centre, reduce the difficulty of lifting, also created condition for adjusting in advance girder steel deformation surplus.In sum, the resulting large-span steel corridor construction of the present invention method has reasonable in design, and the construction plant is little, and speed is fast, and cost is low, and the characteristics of the steel work good stability that obtains of construction.
Description of drawings
Fig. 1 is front view of the present invention;
Fig. 2 is that the present invention uses the auxiliary girder structural representation;
Fig. 3 is that the present invention removes constructing structure schematic diagram behind the auxiliary girder.
The specific embodiment
The invention will be further described by reference to the accompanying drawings below by embodiment.
Embodiment 1:
As shown in the figure, the large-span steel corridor construction method that present embodiment is described as shown in Figure 1, is at first installed the brace steel post 1 of span both sides, and auxiliary girder 2 is installed between two brace steel posts 1.Then as shown in Figure 2,7 lifting transverse horizontal girder steels 3 are then installed support steel beam 8 and diagonal brace girder steel 4 between lower two transverse horizontal girder steels 3 take auxiliary girder 2 as suspension centre.Then as shown in Figure 3, remove auxiliary girder 2, install again two between the transverse horizontal girder steel 3 the vertical levels girder steel and stride girt, the horizontal girder steel 6 that last installation needs.
On the other hand, the elastic deformation that forms because of deadweight by calculating the high-altitude girder steel is when installing take auxiliary girder 2 as suspension centre, respectively according to the position of result of calculation by pulling force cucurbit adjustment transverse horizontal girder steel 3, to adjust the deformation of transverse horizontal girder steel 3.
Claims (3)
