Specific embodiment：
In order to be better understood from the function and purpose of the present invention, and being not interpreted as limiting property solution, below based on
Attached drawing further provides the detailed description of the embodiment of the present invention.
As seen from Figure 1, the faulted-stage mount structure 10 is symmetrical for one, and is distributed in the combination of keel bar both sides
Structure, including left and right half-frame structure 20,20 ' and connection component 30.
Left and right half-frame structure 20,20 ' is all comprising upper ledge 21, lower frame 22, lateral margin attachment angle 23, web connecting members 24,
Multiple pads 25, web connection reinforcement part 26, finger-type band plate 27, L-type faulted-stage angle section 28.Wherein upper ledge 21, lower frame 22 are main
Load-carrying construction part, upper ledge 21 are equipped with multiple reinforcing ribs, while equipped with overhanging bridging arrangement 21a.Upper ledge 21 is with lower frame 22 by outer
Stretch bridging arrangement 21a, lateral margin attachment angle 23, web connecting members 24, multiple pads 25, web connection reinforcement part 26 connects.
Left and right half-frame structure 20,20 ' is connected by connection component 30.
In more detail, upper ledge 21 is overlapped in by overhanging bridging arrangement 21a on lower frame 22, then passes through lateral margin joint angle
Material 23 connects its lateral margin item, since the overhanging bridging arrangement 21a of upper ledge 21 depth of sinking is identical with 22 web thickness of lower frame, overlaps
Upper ledge 21 is flushed with the 22 web back side of lower frame afterwards.
The web connecting members 24 of pectination square aperture structure are respectively arranged in the 22 web back side of upper ledge 21 and lower frame, pectination
Square aperture one side is mounted on 21 apotome of upper ledge upward.Multiple pads 25 and 24 equal thickness of web connecting members, correspond to cloth
It puts in 24 pectination opening of web connecting members, and keeps flushing with 24 edge of web connecting members.Web connection reinforcement part 26 is installed
Above multiple pads 25 and web connecting members 24.The square aperture structure formed after assembling is distributed along faulted-stage edge strip 21c, is used for
Pass through faulted-stage squab panel stringer.
Further, finger-type band plate 27, L-type faulted-stage angle section 28 are installed on web connecting members 24, connect with lower frame 22 successively
It connects, aligns with 24 lower edge of web connecting members.Finger-type band plate 27 after connection, there are gaps between 28 flange of L-type faulted-stage angle section
δ, this gap ensure the sealing of faulted-stage squab panel and power transmission requirement for connecting faulted-stage squab panel covering.
Particularly, connecting plate 35, left and right L-type faulted-stage angle section are installed on web at the 22 back symmetrical centre of left and right lower frame
28 are overlapped on close to one end at symmetrical centre on connecting plate 35 respectively, and being finally overlapped in left and right L-type by V-type connector 36 again breaks
It is connected on rank angle section 28.
The interior edge strip 21b of left and right sides upper ledge 21 is connected by being across the interior edge strip attachment angle 31 of edge strip on keel bar
It connects；Upper ledge 21 web in the left and right sides is pressed from both sides by being distributed in the web connection column 34 of keel beam web both sides in the form of back-to-back
It is close to and connects；The left and right faulted-stage edge strip 21c of both sides upper ledge 21 passes through 32 or so the connection of faulted-stage edge strip joint angle box, the connection of faulted-stage edge strip
Keel beam web is clamped and for example, by the fasteners such as high locked bolts is drawn to connect, another side is respectively with controlling by 32 stile of angle box
The 21c connections of faulted-stage edge strip.Similarly, the hull bottom edge strip of left and right sides lower frame 22 is connected by hull bottom edge strip joint angle box 33.
The present invention is a kind of seaplane faulted-stage mount structure, and whole frame is split as sectional combination structure form, is reduced
Part production difficulty reduces product rejection rate, while improves Standard craftsmanship, can meet the complicated faulted-stage of structure crosslinking
Structure power transmission demand and the watertight requirement in region.
Above said content is the preferred embodiment of the present invention, it is impossible to assert that the specific implementation of the present invention is confined to this
A little explanations.For the engineers and technicians of the technical field of the invention, without departing from the inventive concept of the premise, also
Several simple deduction or replace can be made, should all be considered as belonging to protection scope of the present invention.
