Description
Technical field
The present invention, about a kind of Construction of Steel Structure method, refers in particular to a kind of special-shaped irregular Construction of Steel Structure method.
Background technology
Along with the strength development of China's building trade grows, appearance of city generation acute variation in all parts of the country, new building emerges in an endless stream as emerged rapidly in large numbersBamboo shoots after a spring rain.Nowadays, desirable in conjunction with modern popular architectural aesthetic, designer consummate craftsmanship, has broken through thought binding in the past, and a collection of modern design of design-build is unique, the day by day diversified building of style, reflects strong times flavour.Particularly the moulding of curved-surface building is more and more applied in many domestic and international architectural images.In these buildings, use the irregular steel work of a large amount of abnormity, and these special-shaped irregular steel work are in the past just as the individual monomers in architectural image, be applied on a large scale in whole architectural image now, because the construction weight of irregular steel work is large, moulding is complicated, by transport capacity and install the restriction of crane, cause the produce in factory of component and lifting construction difficulty large, conventional hanging method cannot be adopted to install.
Summary of the invention
Because the problems referred to above, the invention provides a kind of special-shaped irregular Construction of Steel Structure method, comprise the following steps:
1) by the compound beam that irregular for abnormity steel work segmentation is divided into two arc longerons and is connected between two arc longerons by design drawing;
2) steel plate setting-out, cutting, assembling, processing obtains described compound beam and arc longeron;
3) first respectively two arc longeron liftings are put in place, and temporary support columns is set below two arc longerons;
4) again by between compound beam lifting to two arc longerons, compound beam and two arc longitudinal beam weldings are fixed;
5) described temporary support columns is unloaded, complete the installation of special-shaped irregular steel work.
Further improvement of the present invention is, after described temporary support columns unloading, arranges full hall scaffold as support further below the irregular steel work of described abnormity.
Further improvement of the present invention is, described temporary support columns is unloaded by jack.
Further improvement of the present invention is, after compound beam lifting being put in place, below compound beam, arranges temporary support columns.
Abnormity of the present invention irregular Construction of Steel Structure method reasonable, convenient operation, successfully solves the processing of Complex Different Shape steel work and the difficult problem lifted.Adopt the lifting mode of " burst lifts, and combines " in the air, reduce the task difficulty of operating personnel, the mechanically actuated cost of minimizing, improves operating efficiency, ensure that construction quality and safety, shortens the duration.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Coordinate referring to shown in Fig. 1, the step of abnormity of the present invention irregular Construction of Steel Structure method is as follows:
Shown in S1 composition graphs 2, by using the measuring apparatuss such as high precision total station, the softwares such as BIM and AutoCAD are utilized to carry out modeling, the measurements and calculations method of employing science, the compound beam 102 segmentation of irregular for abnormity steel work 10 being divided into two arc longerons 101 and being connected between two arc longerons 101 by design drawing; Preferably resolve the difficult problem that Complex Different Shape irregular steel work surveying setting-out work amount of calculation is large, testing required precision is high, also solve the difficult problem that tilt axis controls simultaneously, to the surveying setting-out technology of the irregular steel work of Complex Different Shape, there is higher directive significance.
The setting-out of S2 steel plate, cutting, assembling, processing obtains described compound beam 102 and arc longeron 101; The setting-out of steel plate cutting mainly adopts computer programming setting-out, and by full-automatic numerical control cutting stock, small part part adopts plate shearing machine for blanking, guarantees the correctness of disparate modules setting-out size, overcomes the error that artificial setting-out produces.
Shown in S3 composition graphs 3, first respectively two arc longeron 101 liftings are put in place, and temporary support columns 20 is set in the below of two arc longeron 101 cambered top end; The top of temporary support columns 20 is provided with jack 201.
Shown in S4 composition graphs 4, then compound beam 102 is lifted between two arc longerons 101, after compound beam 102 lifting puts in place, temporary support columns 20 is also set below compound beam 102, compound beam 102 and two arc longerons 101 are welded and fixed.
Shown in S5 composition graphs 5, described temporary support columns 20 is unloaded by jack 201, complete the installation of special-shaped irregular steel work 10.After temporary support columns 20 has unloaded, in the below of described abnormity irregular steel work 10, full hall scaffold 30 is set as support further.
The flower-shaped steel structural roof of loudspeaker of the irregular curve that Nanning planning museum is made up of seven arc-shaped steel rod structures, construction method of the present invention has been applied in the work progress of roofing, below in conjunction with the constructure scheme of Nanning planning museum, the present invention will be further described.The constructure scheme of Nanning planning museum comprises the following steps:
1) by design drawing, the crossbeam that the irregular steel structural roof segmentation of museum is divided into plural Pin arc steel structure and is connected between each arc steel structure is planned in Nanning, then by compound beam 102 that the segmentation of every Pin arc steel structure is divided into two arc longerons 101 and is connected between two arc longerons;
