Description

A kind of steel construction of boiler steel frame
Technical field
The utility model relates to a kind of steel construction of construction engineering technical field, specifically the steel construction of the boiler steel frame of a kind of support and protection boiler.
Background technology
In boiler manfacturing and running, boiler steel frame is the main support member of boiler, has important effect.Simultaneously along with China's economy and social fast development, boiler capacity also meets production and life requirement in corresponding increase, the corresponding increase bringing boiler loading of the increase of boiler capacity, steelframe as the main supporting member of boiler also there will be the situations such as oversize, the span of steelframe, depth of section are still conducted oneself with dignity all to be increased a lot, transport inconvenience will be caused, and the unsafe factor of respective members in installation process may be occurred.
Utility model content
The utility model provides a kind of steel construction of boiler steel frame, and its structure is simple, and efficiency of construction is high, cost-saving, can reduce freight simultaneously, and ensure product quality.
The utility model realizes with following technical scheme: a kind of steel construction of boiler steel frame, it comprises large girder, large girder comprises, the upper beam of the I-shaped shape that lower two parts are superimposed with each other and the underbeam of I-shaped shape, upper beam comprises upper beam wing plate, upper web, upper beam flanged plate, the two ends of upper web respectively with upper beam wing plate, the groove welding of upper beam flanged plate connects, underbeam comprises underbeam flanged plate, lower web, underbeam wing plate, the two ends of lower web respectively with underbeam flanged plate, the groove welding of underbeam wing plate connects, upper beam flanged plate is connected by multiple high-strength bolt at superposed surfaces place with underbeam flanged plate, upper beam and underbeam adopt identical steel to make.
Meanwhile, in order to meet the requirement of local stability, upper web is welded with two the first longitudinal reinforced ribs along on upper beam span direction, the two ends of upper web are welded with ribbed stiffener with upper beam wing plate, upper beam flanged plate respectively; Lower web is welded with two the second longitudinal reinforced ribs along on lower beam span direction, and the two ends of lower web are welded with ribbed stiffener with underbeam flanged plate, underbeam wing plate respectively;
For the superposed surfaces place of upper and lower beam, upper beam flanged plate and underbeam flanged plate offer multiple bolt hole respectively, the bolt hole alignment of upper beam flanged plate and underbeam flanged plate, adopts high-strength bolt to connect.
The utility model passes through separated in the web of large girder, superposed surfaces place adopts flanged plate to pass through high strength exploitation again, the size of component reduces greatly, and by the accurate Milling Machining to flanged plate end face, ensure that the perpendicularity of large girder entirety also can control the height of web.
Therefore, namely the utility model can meet installation requirement in work progress and movement requirement, and can use by Assembling.
Accompanying drawing explanation
