Abstract
The utility model relates to an adopt blue steel shotcrete of submerged arc angle welding method, its characterized in that: including steel pipe, flange and reinforced rib plate, the flange is located the steel pipe both ends, and the perpendicular to pipe welding, adopt the submerged arc welded corner joint between flange and the steel pipe, form submerged arc fillet welding foot between flange and the steel pipe, the welding has the reinforced rib plate of circumference interval arrangement between flange and the steel pipe. This adopt blue steel shotcrete of submerged arc angle welding method, structural design scientific and reasonable adopts submerged arc angle welding process, guarantees the welding quality of product to easy operation, facilitate promotion and application.
Description
Technical field
The utility model belongs to the deep foundation pit support fields such as subway, high ferro, large-scale work China Democratic National Construction Association, relates to steel pipe and the flange welding of bracing members product, especially a kind of bracing members adopting submerged arc fillet welding flange.
Background technology
Deep foundation pit support in subway work generally adopts steel shotcrete support form, but due to the flange of bracing members and the problems of welded quality of its middle steel tubing portions, often there is the bracing members flange accident that drops to occur, cause bracing members slump accident further, cause more serious human casualty accident.
At present, the flange of bracing members product and the steel tubing portions mode that generally adopts carbon dioxide gas arc welding to connect.This kind of welding manner, first needs to carry out groove process to the welding end of steel pipe, to increase welding penetration, ensures weld strength.Because manufacturer is for controlling and reducing cost of labor, substantially all can not reach the requirement of steel pipe groove process, be easy to cause the fusion penetration degree welded between steel pipe with flange inadequate, weld strength is not good enough.Thus bury and weld hidden danger between flange with steel pipe.
Therefore, for the production status of current bracing members, taking a kind of welding procedure reliably, guarantee the welding quality between flange and steel pipe, is the very necessary measure ensureing bracing members product quality.
Through retrieval, do not find correlation technique.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of welding manner reliable, ensure welding quality, simple to operate, the bracing members of being convenient to the employing submerged arc fillet welding flange promoted.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of bracing members adopting submerged arc fillet welding flange, it is characterized in that: comprise steel pipe, flange and deep floor, described flange is positioned at steel pipe two ends, and perpendicular to described steel-pipe welding, submerged arc welded corner joint is adopted between described flange and steel pipe, form submerged arc fillet welding leg between described flange and steel pipe, between described flange and steel pipe, be welded with the deep floor that the circle spacing arranges.
And be shaped with chamfering bottom described deep floor, this chamfering avoids the submerged arc fillet welding leg between described flange and steel pipe.
And described steel pipe length is 0.5 meter-9 meters, diameter is 400 millimeters-1000 millimeters, and described thickness of steel pipe is 10-30 millimeter.
And described flange thickness is 10-30 millimeter.
Advantage of the present utility model and beneficial effect are:
1, the bracing members of this employing submerged arc fillet welding flange, adopts submerged arc welded corner joint between flange and steel pipe, and penetration is dark, at utmost ensures the welding quality safety between flange and steel pipe, and the generation decreasing splashing of maximum possible.
2, the bracing members of this employing submerged arc fillet welding flange, is shaped with chamfering bottom deep floor, and this chamfering avoids the submerged arc fillet welding leg between described flange and steel pipe, for avoiding the dimensional interference between submerged arc fillet welding leg.
3, the bracing members of this employing submerged arc fillet welding flange, steel pipe length is 0.5 meter-9 meters, and diameter is 400 millimeters-1000 millimeters, described thickness of steel pipe is 10-30 millimeter scope, flange thickness is 10-30 millimeter, can form multiple series of products, meets different customer demand.
4, the bracing members of this employing submerged arc fillet welding flange, scientific structure design is reasonable, adopts submerged arc welded corner joint technique, ensures the welding quality of product, and simple to operate, be easy to be extended and applied.

Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of bracing members adopting submerged arc fillet welding flange, it comprises steel pipe 2, flange 1 and deep floor 3, flange is positioned at steel pipe two ends, and perpendicular to steel-pipe welding, submerged arc welded corner joint is adopted between flange and steel pipe, form submerged arc fillet welding leg 4 between flange and steel pipe, between flange and steel pipe, be welded with the deep floor of circle spacing layout.Adopt submerged arc welded corner joint, penetration is dark, at utmost ensures the welding quality safety between flange and steel pipe, and the generation decreasing splashing of maximum possible.Be shaped with chamfering 5 bottom deep floor, this chamfering avoids the submerged arc fillet welding leg between described flange and steel pipe.Avoid the dimensional interference between submerged arc fillet welding leg.
Steel pipe length is 0.5 meter-9 meters, and diameter is 400 millimeters-1000 millimeters, and described thickness of steel pipe is 10-30 millimeter scope.Flange thickness is 10-30 millimeter.Multiple series of products can be formed, meet different customer demand.Installing hole on flange, according to different customer requirement, can be uniformly distributed varying number.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
