The present invention relates to a kind of assembled fish belly corrugated web girder steels, the flat web H fashioned iron including being located at two side ends section, the variable section H-type steel with longitudinal stiffener positioned at the Ripple Sternum of interlude and between interlude and end segments；The flat web H fashioned iron section is connect with the band variable section H-type steel section by high-strength bolt；The variable section H-type steel section is connect with the Ripple Sternum section by high-strength bolt.The present invention is suitable for the roofing large span secondary beam of industry with civil buildings, matches girder steel stress curve, and stock utilization is high, and each section of girder steel is bolted, and constructs easy to assembly.
Description
Technical field
The invention belongs to steel building fields, and in particular to a kind of assembled fish belly corrugated web girder steel.
Background technique
Traditional H-type Simply-supported Steel Beams, web is thicker because of ratio of height to thickness requirement, typically constitutes from 40% of total weight or so, web
Stock utilization is lower；According to corrugated web girder steel, sheared in the end of beam it is maximum, end junction web generally require compared with
Thick end plate is converted, and the relatively thin corrugated web of end segments may can't pass shearing resistance checking computations；And under Uniform Load, etc.
Section Simply-supported Steel Beams are there are end bending moment ratio mid span moment is small, thus the situation for causing the stock utilization of girder steel end segments low.
In addition, being limited by transport and live loop wheel machine, girder steel needs to carry out fragmented transport and hangs when girder steel span is larger
Dress.And when assembly is welded at the scene, there are welding adverse conditions, weldquality is difficult to ensure, while there is also welding efficiencies
Low problem.
Summary of the invention
The purpose of the present invention is to provide a kind of assembled fish belly corrugated web girder steels, to solve under Uniform Load,
The low problem of Simply-supported Steel Beams stock utilization and segmentation girder steel site welding quality are difficult to ensure and welding efficiency is low asks
Topic.The present invention is suitable for the roofing large span secondary beam of industry with civil buildings.
To achieve the above object, the technical solution that the present invention specifically provides are as follows: a kind of assembled fish belly corrugated web girder steel,
Flat web H fashioned iron including being located at two side ends section, positioned at the Ripple Sternum of interlude and positioned at interlude and end
The variable section H-type steel with longitudinal stiffener [effect does not illustrate] between section；The flat web H fashioned iron section and the band variable cross-section
H profile steel section is connected by high-strength bolt；The variable section H-type steel section and the Ripple Sternum section are connected by high-strength bolt
It connects.
Optionally, described flat web H fashioned iron one end is equipped with end plate and triangle stiffener；The flat web H fashioned iron end plate
It is flushed with the flat web H fashioned iron top flange, stretches out the flat web H fashioned iron bottom wing outside the flat web H fashioned iron end plate lower part
Edge；The triangle stiffener is connect with the flat web H fashioned iron lower flange and the flat overhanging position of web H fashioned iron end plate.
Optionally, the variable section H-type steel both ends are equipped with end plate and triangle stiffener；The variable section H-type steel end plate
It is flushed with the variable section H-type steel top flange, the variable section H-type steel bottom wing is stretched out outside variable section H-type steel end plate lower part
Edge；The triangle stiffener is connect with the variable section H-type steel lower flange and the overhanging position of variable section H-type steel end plate.
Optionally, the Ripple Sternum both ends are equipped with end plate and triangle stiffener；The Ripple Sternum
End plate is flushed with Ripple Sternum top flange, and the corrugated web H-type is stretched out outside Ripple Sternum end plate lower part
Steel lower flange；The triangle stiffener and the Ripple Sternum lower flange and the Ripple Sternum end plate are overhanging
Position connection.
Compared with prior art, the present invention fully considers mechanical characteristic of the simply supported beam under evenly load, using ripple abdomen
Plate, the flat web H fashioned iron of variable section H-type steel and end more match its stress curve, improve the utilization rate of girder steel material, are a kind of
The good structure of economy.Longitudinal stiffener especially is set in variable section H-type steel section, the thickness of its web is thinned, into one
The utilization rate of the raising steel of step.Since the present invention is applied to the roofing large span secondary beam of industry with civil buildings, girder steel upper limb
Edge is in pressured state, therefore the end plate of each segment end portion of girder steel is flushed with its top flange, facilitates the laying of roof boarding, construction is just
Benefit.Furthermore each segmentation of girder steel is connected using high-strength bolt, easy to assembly, is improved site operation efficiency and is avoided the occurrence of weldering
Connect the problem of quality is difficult to ensure.
