Description
Technical field
The present invention relates to the bridge construction construction field, relate in particular to a kind of Pier Formwork manufacture method.
Background technology
Bridge pier generally means the intermediate support structure thing in the multispan bridge.It produces vertical force, horizontal force and moment of flexure except bearing superstructure, also bears wind-force, flowing water pressure, and the impact of contingent seismic force, ice pressure, ship and drift.Columnar pier is the bridge pier pattern extensively adopted in current highway bridge.It is simple and direct, lucid and lively, attractive in appearance that it has lines, not only saves material quantity but also have the characteristics of easy construction, is specially adapted to Urban Bridge and viaduct that bridge width is larger.Columnar pier generally can be divided into the forms such as only post, twin columns and multicolumn, it can be wide according to bridge needs and geomorphological features condition any combination, columnar pier is comprised of cushion cap, pillar pier shaft and bent cap, for superstructure, is large cantilever box section, pier shaft can be directly and beam join.
Along with the develop rapidly of China's capital construction, present urban architecture structure not only only considers that it uses function and security, the another key factor that has become Architectural Structure Design attractive in appearance.In recent years, for this frame bridge, people more and more are discontented with and are enough to front square-folded pier stud outward appearance, because the curved surface pier stud has rational stress and novel outward appearance, therefore more and more are subject to people's favor.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of simple in structure, lines are simple and direct, elegant in appearance can recycling, the novel Pier Formwork manufacture method of easy accessibility, reduction workmen's labour intensity.
For achieving the above object, the technology used in the present invention solution is: a kind of Pier Formwork manufacture method, comprise setting-out and number material, cutting, part rectification, parts spelling, template welding, weld inspection and the application of spraying paint, and specifically comprise the following steps successively.
Described setting-out and number material, welding allowance for shrinkage when setting-out and number material should be reserved making and installation and cutting, He Xi limit, plane limit allowance, should check the trade mark, specification, the quality of steel material before number material, when finding that the steel material is not straight and have the dirts such as erosion rust, paint to affect quality, material again number after should correcting, clearing up, number material appearance and size permissible variation is ± 1mm, shaped steel line of cut and edge-perpendicular degree permissible variation are ± 2.0mm, number the material before sheet material must flatten processing, check material, the clout after blanking must the brushing mark simultaneously.
Described cutting, the cutting of the main parts size of Pier Formwork (as flange) will adopt accurate cutting (as numerical control, surface trimming), and hand cut only is suitable for the part that the cutting back edge still needs machining; The edge of mechanical shearing blanking should be neatly, without defects such as burr, anti-mouths, plate shearing deviation length and width degree is ± 2.0mm; The permissible variation that cuts rear accessory size should meet: automatic, semi-automatic be cut into ± 2.0mm, hand cut is ± 2.0mm.
Described part is corrected, and mainly adopts mechanical gagging or heat straightening, and when its main stressed part cold-working is crooked, after the cold-working bending, part edge must not crack, the steel material surface after gagging do not have obvious indenture and other damages, otherwise still need to carry out shaping; While adopting heat to rectify, heat is rectified temperature and should be controlled and be manufactured on 600～800 ℃, forbids burning, and after correcting, the part temperature is answered Slow cooling, is down to before room temperature, must not hammering part steel, forbid water quenching.
Described parts spelling must carry out on special-purpose platform or in fetal membrane, and the spelling location-plate should be set on platform or moulding bed, to guarantee the position of parts; Described parts spelling is sequentially: connecting flange → circular arc panel → seam → rib, the steel member after spelling is qualified, should stamp at the regulation position numbering mark.
Described template welding; adopt the welding manners commonly used such as CO2 gas shielded arc welding and manual electric arc welding; should check again whether cracking of the cleaning quality on surface, position to be welded and tack welding weld seam before welding;=welding condition should be debugged in advance on unofficial workpiece, checks the equipment used, full weld between rib; flange and panel full weld; the weldering height is 6mm, and the welding of rib and panel 15%, weld the high 5mm of being.
Described weld inspection, at first carry out visual examination of weld, and all weld seams all should carry out 100% visual examination after weld seam is cooling, face of weld should be evenly, smoothly, non-wrinkle, interruption and incompletely filling, and be connected gently with base metal, forbid that crackle is arranged, the defect such as incomplete fusion; Secondly overlap or too high weld seam, adopt the method for grinder buffing that unnecessary weld metal is ground off, and then the defects such as face of weld pit, undercut or weld size deficiency, first clean out face of weld, then carry out repair welding; Last excessive pore, slag inclusion, incomplete fusion, defects i.e.cracks, adopt the method for carbon arc air gouging and grinder buffing that defective weld seam is removed, then repair welding.
The described application of spraying paint, at first carry out surface-treated quality examination and cleaning (dust, grease, moisture) before application, can carry out application after qualified; Secondly coating requires smoothly, even, and paint film is without bubble, wrinkle, without serious sagging, come off, the defects such as pin hole, crackle, holiday, the finish paint color is consistent with colorimetric card; Then during application, Tu Fuliang is 200g/m
2, the layer of lacquer film thickness is 40 μ m, with mixed earth contact-making surface, can not spray paint.
The present invention has following beneficial effect in sum: the present invention with respect to the simplification of other Pier Formwork manufacture method, effectively improve intensity and the precision of Pier Formwork by its rational selection, cutting, spelling, welding and application, reduced to a great extent traditional steel form exist from great, repeat usage is low, dismounting is difficult, operator's labour intensity is large, and the problem such as construction quality is not high, the pier stud lines that make it build out are simple and direct, elegant in appearance.
