Description
Technical field
The template that the utility model is related to be used in the wet seam construction of bridge, specially a kind of wet seam stainless steel of bridge
Plate bed die is particularly suitable for the construction of the wet seam of bridge of spanning existing railway.
Background technology
In recent years, with the fast development of Chinese economy, urban size also gradually expands, the railway positioned at suburb slowly melts
Enter city or the center as city, overcrossing railway becomes municipal bridge and designs unavoidable major issue.Due to railway phase
To closure, precast beam is widely used in overcrossing railway detail design.Wet seam, which is constructed, after erection of precast beams is
Inevitably, but due to the closure, timeliness, spatiality of overcrossing railway construction.How in the interior wet seam of guarantee of block point
Construction safety, quality, progress and ensure railway operation safely become construction key factor.
The wet seam construction of common bridge domestic at present is all made of wooden model as wet joint template, is needed after having poured concrete
It removes, this construction method installation form need to hang mould above rail track, and need to put into a large amount of labours, equipment, have in block point
All difficulty is completed in construction in the time of limit, and security risk is larger.
Invention content
The purpose of this utility model is to ensure railway operation safety, reduction risk, reduction working sources input, shortening work
Phase reduces difficulty of construction, provides a kind of stainless steel plate bed die without form removal for the construction of wet seam.
Above-mentioned technical problem is solved, the technical solution adopted in the utility model is：A kind of wet seam stainless steel plate of bridge
Bed die, including stainless steel plate, spaced U-shaped hanging ring on stainless steel plate top surface.
It is as follows using the stainless steel plate bed die construction procedure：Stainless steel plate bed die is temporarily fixed at precast beam before hanging beam
On the reserved steel bar of both sides, unified determine of every beam fixes stainless steel plate in identical side, is lifted to bridge with precast beam
Position.Stainless steel plate within the scope of beam body diaphragm plate both sides 1m is not installed temporarily, is being installed after diaphragm plate has constructed form removable.
Stainless Molding Board with beam body simultaneously lift after, carried in translation, it is closely connected with prefabricated beam flange plate bottom, after wedging with beam-ends reserving rib
It is welded and fixed.Processing is sealed to stainless steel plate and the uncompacted place of flange plate, pours wet joint concrete, wet seam is applied
Work is completed.
The utility model is tentatively installed, is lifted, stainless steel plate for the wet seam construction of overcrossing railway precast beam, stainless steel plate
Accurate adjustment is installed, and consolidation is in place；Stainless steel plate bed die and the closely connected not tight position of beam bottom are handled, wet seam reinforcing bar is bound,
Wet joint concrete is poured, wet seam construction is completed.The utility model solves that Business Line construction risk is big, and form removal difficulty etc. is asked
Topic reduces construction input, shortens the construction time.

Specific implementation mode
A kind of bridge wet seam stainless steel plate bed die, including stainless steel plate 2, stainless steel plate are arranged at intervals with U on 2 top surface
Type hanging ring 1.
The technical solution protected to the requires of the utility model below in conjunction with attached drawing and an example illustrates.
Newly-built Shuozhou City develops Lu Huihe bridge overcrossing railway Grade Separation Projects by being formed across railway and non-across railway two parts,
40m prefabricated PC concrete box girders are used with the parts Pu Tie superstructure across north, 60 total, 59 wet seams, wherein
Elongated wet seam 6, with end, in and 1/4 crossbeam 53, the wet seam length of per pass be 40m.Steps are as follows for Specific construction：
1. as shown in Figure 1, Figure 2, Figure 3 shows, stainless steel plate die structure schematic diagram.
The wet joint gap of this bridge is 42.3cm, thickness 18cm, prefabricated case beam flange plate U-shaped steel muscle protruded length 19cm.
It is computed wet seam stainless steel plate bed die and uses 6mm thickness OCr13 stainless steel plates, the wide 54.3cm of stainless steel plate, stainless steel plate welding
20 U-shaped hanging rings of HPB300 Φ, hanging ring spacing 30cm.
The professional processing factory of stainless steel plate bed die commission is processed making, and hanging ring is welded with steel plate using welding rod special for special.
Wet seam length between consideration stainless steel plate raw material size, piece weight and crossbeam, determines every piece of bed die when processing
Length；Be computed stainless steel plate bed die specification be 1550 × 543 × 6mm, 1250 × 543 × 5mm, 1080 × 543 × 5mm,
517 × 543 × 5mm, 470 × 543 × 5mm, 250 × 543 × 5mm etc..
2. as shown in figure 4, stainless steel plate bed die is tentatively fixed, lift.
Steel plate should be temporarily fixed at before hanging beam on the reserved U-shaped steel muscle of the wet seam in beam both sides by stainless steel plate bed die（It will
Hanging ring and reserved U-shaped reinforcement welding）, every beam is unified to be determined in identical side fixation steel plate, is lifted with prefabricated case beam
To bridge location.Steel plate within the scope of the 1m of diaphragm plate both sides is not installed temporarily, is being installed after diaphragm plate has constructed form removable.
3. as shown in figure 5, the translation of stainless steel plate bed die, promotion are adjusted.
After stainless steel plate bed die lifts simultaneously with beam body, carried in translation, it is closely connected with prefabricated case beam flange plate bottom.
4. stainless steel plate bed die as shown in Figure 6 is fixed.
After stainless steel plate and prefabricated case beam flange plate bottom are closely connected, wedging is simultaneously welded and fixed.
5. as shown in Figure 7, Figure 8, wet seam casting concrete.
To ensure that stainless steel plate bed die is fully sealed with prefabricated case beam flange plate bottom surface, not closely connected place is handled
Ensure seamless, binds wet seam reinforcing bar, then pour C50 concrete, stainless steel plate bed die and concrete placings are integral, wet seam
Construction is completed.
