Description
Technical field
The present invention relates to a kind of preparation method and structure of high narrow big aperture main longitudinal grider down-the-hole arc door, belong to water conservancy and hydropower work
Journey metal structure technical field.
Background technology
Traditional main longitudinal grider down-the-hole arc door for two arm supports up and down double cantilever main longitudinal grider frame structures, main longitudinal grider and
Other supporting constructions are generally not provided between support arm, according to《Hydroelectric project steel-slag sand design specification》（NB35055-2015）, mesh
Preceding domestic Metal Structure Design uses allowable stress method, for main longitudinal grider, selects sectional dimension with span centre maximal bending moment, then lead to
The sectional dimension for crossing selection checks whether its intensity, rigidity and stability meet code requirement, therefore, and the master of mid span moment greatly indulges
Beam, its sectional dimension is also larger, is especially more protruded in the narrow big aperture down-the-hole arc door of height, because of two support arm center main longitudinal grider spans
It is larger, therefore the mid span moment of main longitudinal grider is also larger under effect of water pressure, main longitudinal grider sectional dimension can be caused larger, gate weight
Amount increase is more, and economy is poor；In addition, the general hanger of down-the-hole arc door is arranged at the top of gate flap, using single cylinder swing type hydraulic
Machine is operated, because hydraulic press stroke is big compared with gate height, then uses single cylinder swing type hydraulic machine in the narrow big aperture down-the-hole arc door of height
There is stroke long, manufacture, transport and the main difficult technical such as installation difficulty is big；For gate dam engineering, also exist outside hydraulic press
Dew part is more, and engineering aesthetic property is poor, hydraulic press cylinder is largely exposed in air easily occurs the skills such as corrosion and destruction for a long time
Art problem, particularly with low gate dam engineering, gate pier is also resulted in sometimes highly to be increased, increase investment it is more, Technical Economy compared with
Difference；For main longitudinal grider, the blanking of flange plate expansion body makes after flange plate, girder web plate, girder before general girder, overall in factory
Welded again with panel after processing, this difficulty for conventional port size gate is little, but for the narrow big aperture down-the-hole of height
Arc door is just difficult realization, such as some hydropower station sluice port size 8 × 16（It is wide × high）, the nearly 40m of design head, its main longitudinal grider
Processing length is up to more than 20 meters, and flange plate between support arm because there is connection to carry out bending and contacting with support arm connecting plate twice thereafter
Face will be finished, and process very difficult according to monoblock steel plate cutting, and use bolt because being connected with support arm, and bolt is pacified
Equipped with space requirement, this can be caused, and the width of rear flange plate is larger, and waste of materials is more, in addition, support arm and main longitudinal grider screw palpus
All contraposition bolt could complete assembling, and in-site installation difficulty is also larger.In summary：The high narrow big aperture of prior art is main vertical
Beam down-the-hole arc door also Shortcomings, await further perfect.
The content of the invention

Hydraulic press manufacture difficulty, and without setting headstock gear operating platform on gate top, make dam facing arrangement neat and artistic；The face of gate flap
Plate is supported on the Liang Geshang being made up of main longitudinal grider, vertical secondary beam, Transverse beams, side column and shackle plate, with improve arc door stability and
The rigidity of whole gate；The rear flange plate of main longitudinal grider uses sectional making, to reduce the convenient processing of cutting length, and reduces scene
The difficulty of assembling.
The high narrow big aperture main longitudinal grider down-the-hole arc door of one kind of the invention being formed as described above, the structure includes door
Leaf, gate flap includes beam lattice, and the upstream face of beam lattice is provided with panel；In the middle part of the back side of beam lattice or bottom is provided with a pair of symmetrical cloth
The shackle plate put, shackle plate is cut with scissors through twin-tub hanging hydraulic press and the branch free bearing being embedded in the second stage concrete of gate pier both sides respectively
Connect；Beam lattice above and below shackle plate are connected through support arm bottom plate with support arm respectively；Divide between two support arms and beam lattice back side
Not She You diagonal brace, diagonal brace bottom is provided with diagonal brace bottom plate, and diagonal brace bottom plate is connected with beam lattice；Provided with perpendicular support between two support arms；Liang Ge
Including symmetrical a pair of main longitudinal griders, a pair of main longitudinal griders are connected through one group of crossbeam, are connected between one group of crossbeam with vertical secondary beam；
Crossbeam includes pedestal crossbeam and needle beam；One group of crossbeam two ends is connected with side column and shackle plate, and shackle plate is located at one group of crossbeam
Longitudinal middle part or bottom, shackle plate is provided with runner device, hanger hole and enters manhole, and hanger hole both sides are provided with earhole reinforcing plate；
Side column includes upper side column and lower side column, above shackle plate for upper side column, below shackle plate for lower side column；Top
Provided with one group of freely-supported side wheel on the outside of post and lower side column.
In said structure, the main longitudinal grider includes a pair of symmetrical webs, and the shape of web is similar to arc plate；A pair
Reinforced plate connection between symmetrical web, reinforcing plate is provided with into people's slotted hole；The back of the body of a pair of symmetrical webs
Water side edge of a wing after main longitudinal grider is connected, and the edge of a wing includes upper rear flange plate, the connection rear wing being from top to bottom arranged in order after main longitudinal grider
Listrium, in after flange plate, connection after flange plate and lower rear flange plate；Flange plate is provided with one group of bolt hole after connection；After connection
