Description
Technical field
The present invention relates to construction of railways technical field, and in particular to one kind is used for prefabricated case beam monoblock type girder falling, energy
Enough meet that 8 grades of earthquake intensitys, dynamic peak value are not less than requirement of the 0.3g geological processes to railroad bridge fall arrest performance.
Background technology
The prefabricated case beam of railroad bridge is the buffer unit for connecting track with supporting pinner, and it is by the bearing of both sides with
The bridge pier connection being just grounded, if running under the effect of the special loads such as earthquake, bearing occur it is damaged, prefabricated case beam can occur laterally or
Length travel, so as to cause the inclination of track, skew, very big risk is brought to railway operation.
The content of the invention
The present invention provides a kind of prefabricated case beam monoblock type girder falling, prefabricated under the effect of the special loads such as earthquake for preventing
The laterally or longitudinally displacement of box girder body structure.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of prefabricated case beam monoblock type girder falling, including beam body plane, the fastener inserts for being fixedly connected on beam body plane upper end,
And the stop component of beam body plane lower end is fixedly connected on, the stop component includes long baffle plate, the short gear of opposite side of side
Plate, and for connecting the connecting plate of long baffle plate and short shutter.
Further, the fastener inserts include the first pre-buried T steel, the second pre-buried T steel and the 3rd pre-buried T steel, and this first
Pre-buried T steel be arranged in parallel with the second pre-buried T steel, the 3rd pre-buried T steel be arranged vertically within the first pre-buried T steel and the second pre-buried T steel it
Between.
Preferably, the lateral surface of the long baffle plate is provided with yielding rubber pad.
Preferably, the lower end side of the connecting plate has the horizontal side flushed with long baffle plate.
Further, the surface of the stop component is provided with anticorrosive coat, and the anticorrosive coat includes polynary successively from the inside to the outside
Alloy co-penetration layer, passivation layer and polyurethane epoxy zinc-rich top coat layer.
From above technical scheme, the present invention is used as falling proof device in railroad bridge prefabricated case beam, use is pre-buried,
The unitary design of block and beam body, avoiding the connecting bolt loosening of traditional girder falling product causes asking for limit function failure
Topic.

Embodiment
A kind of preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
As Figure 1-3, girder falling includes beam body plane 1, is fixedly connected on the fastener inserts 2 of beam body plane upper end, with
And it is fixedly connected on the stop component 3 of beam body plane lower end.Beam body plane is fixedly connected with fastener inserts and stop component, three
Integrated design, effectively provide the stability and durability of structure.
The fastener inserts 2 include the first pre-buried T steel 21, the second pre-buried 22 and the 3rd pre-buried T steel 23 of T steel, and this is first pre-
T steel is buried to be arranged in parallel with the second pre-buried T steel, the 3rd pre-buried T steel is arranged vertically between the first pre-buried T steel and the second pre-buried T steel,
The both ends of 3rd pre-buried T steel have certain gap with the second pre-buried T steel and the 3rd pre-buried T steel.All opened on three pre-buried T steel
Provided with multiple through holes, the adhesion between concrete is improved.
The stop component 3 includes long baffle plate 31, the short shutter 32 of opposite side of side, and for connect long baffle plate with
The connecting plate 33 of short shutter, the lower end side of the connecting plate have the horizontal side 331 flushed with long baffle plate, are ensureing preferably ground connection
While support performance, reduce material cost to greatest extent.
The lateral surface of the long baffle plate 31 is provided with yielding rubber pad 34, and the rigidity between anti-stop block and support pinner is touched
Hitting causes falling proof device structure to be destroyed.
As shown in figure 4, the surface of the stop component 3 is provided with anticorrosive coat 4, the anticorrosive coat includes more successively from the inside to the outside
First alloy co-penetration layer 41, passivation layer 42 and polyurethane epoxy zinc-rich top coat layer 43, using multi-layer anticorrosion processing mode, its salt spray resistance
Property experiment can reach more than 1500h.
As shown in figure 5, prefabricated case beam 5 is contacted by the bearing 51 of both sides with the support pinner 61 of lower section bridge pier 6, two anti-
Fall the bottom that beam 7 is mounted in prefabricated case beam, between side supports, the upper end of girder falling by fastener inserts 2 with it is prefabricated
Box beam connects, and has certain gap between the stop component 3 and bridge pier of girder falling lower end.During installation, the outside of long baffle plate 31
Face is close to support pinner 61, rigid collision that the yielding rubber pad 34 on its surface can be between anti-stop block and support pinner.When
When occurring due to special loads such as earthquakes, because side supports breakage loses support force, girder falling is now applied to prefabricated case beam
On bridge pier, support effect is completed, prevents the laterally or longitudinally displacement of prefabricated case beam girder construction.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, technical side of the those of ordinary skill in the art to the present invention
The various modifications and improvement that case is made, it all should fall into the protection domain of claims of the present invention determination.
