Description
Technical field
The present utility model is related to railway traffic engineering technology, specifically a kind of changeable type steel bridge maintenance step
Plate.
Background technology
With China's expanding economy, railway, the increase of highway construction and state return home the implementation of production capacity policy, in the present
In road construction afterwards, steel structure bridge will be more and more, when steel structure bridge box baseplate uses non-monolithic structure,
Inevitably encounter the setting maintenance step plate on lower horizontal-associate the problem of, if routinely mixed using integral plate or reinforcing bar
Concrete board necessarily will appear the problem that weight is big, difficult to install, cost is high, therefore study a kind of not only economic but also safety maintenance
Step plate is very important.
Maintenance step plate in conventional railway steel structure girder has integral plate and armoured concrete slab etc., using integral plate
Or armoured concrete slab, it is that weight increases first, has an adverse effect to the whole stress of girder steel；Secondly difficult to install, maintenance
It replaces difficult；It is exactly cost height to have again.
Invention content
The purpose of this utility model is that in view of the above-mentioned deficiencies in the prior art, providing a kind of changeable type steel
Bridge maintenance step plate, light weight is fabricated separately, easy for installation, and maintenance and replacement is also convenient for, and is examined when being arranged in railway steel structure girder
When repairing step plate, it is contemplated that weight, installation and maintenance convenience and saving cost should not use integral plate and armoured concrete slab
When, the changeable type steel bridge maintenance step plate using the utility model is to solve the setting maintenance step plate in railway steel structure girder most to pass through
Ji and feasible scheme.Can avoid using monoblock steel plate or armored concrete step strip come weight it is big, difficult to install, cost is high
The problem of, step plate weight substantially reduced can be overhauled, cost is reduced, is easily installed the maintenance and replacement with operation stage, in railway
Setting changeable type steel bridge overhauls step plate inside steel bridge, is a kind of novel processing mode.
To solve the above problems, the utility model uses following technical scheme：
Changeable type steel bridge maintenance step plate, including girder steel, bottom horizontal connecting plate, web, vertical ribbed stiffener, I-shaped steel longitudinal beam
With steel Turbogrid plates, the web of girder steel both sides and vertical ribbed stiffener are connected by the way that bottom horizontal connecting plate is arranged in steel beam bottom, the bottom of at
I-shaped steel longitudinal beam is set on cross connecting plate, steel Turbogrid plates are laid on I-shaped steel longitudinal beam.
Preferably：The steel Turbogrid plates are made of side wrapped plate, cross bar and load band steel, are laterally arranged one every 25mm
The load band steel of high 25mm, thick 5mm, transverse width are adjusted according to web spacing, and longitudinal mono- section of 4m that presses carries out factory's making,
Between high 25mm, the side wrapped plate of thick 5mm every 1m be arranged a high 5mm, the cross bar of thick 5mm, beam-ends according to beam length need into
Row adjustment, each section are all made of the making of Q235 steel.
The utility model changeable type steel bridge maintenance step plate has the following advantages：
（1）Changeable type steel bridge maintenance step plate can solve the problems, such as the setting maintenance step plate in railway steel structure girder.
（2）Its is light-weight, and installation and replacement are convenient, and service personnel walks steady comfortable above, and appearance is preferable.
（3）Engineering can be safely performed more, short time limit, save engineering cost, economical rationality, technological innovation.
