Description
Technical field
This utility model belongs to technical field of bridge engineering, is specifically related to the composite steel concrete bridge of a kind of dry and wet seam
Panel.
Background technology
Medium and small span and the widest cable-stayed bridge of bridge floor use concrete girder both economical, but concrete deck cable stayed bridge across
Degree is the most relatively difficult with design more than construction during 30m more than 500m or width, and construction quality is not easy to ensure.Combination beam is oblique
Drawing bridge concrete to bear most girder pressure, concrete slab is than Orthotropic Steel Bridge Deck economy；Combination beam is oblique
Draw the girder of bridge, crossbeam and precoated plate all can use primary structural component, it is easy to transport and install；Girder steel field bolted, precast concrete
Floorings situ wet joint connects；Compared with whole concrete girder, combination beam cable-stayed bridge crane gear is smaller and the most dry
Joint；Compared with the cable-stayed bridge of all steel girder, combination beam cable-stayed bridge steel using amount is few, requires low to traffic condition.
In traditional combination beam cable-stayed bridge, weldering follow closely main uniform close be arranged in steel girder top flange, crossbeam top flange with
And stringer top flange end face.In order to reduce the concrete shrinkage effect adverse effect to structural system stress, general employing is pre-
Concrete slab processed.During floorings construction, the most hoisting prefabricated concrete slab is in place, then completes executing of wet seam
Work, makes prefabricated bridge be linked to be entirety, last stretch-draw vertically and horizontally presstressed reinforcing steel with steel girder by the weldering nail of both faying faces.So
And effect of contraction concrete slab vertically and horizontally deformed due to steel girder and gooseneck so that put on concrete bridge deck
The reduction of effective prestress in plate.For this reason, it is necessary to design and work progress to steel-concrete combined structure bridge are entered
Row optimizes, to reach shorten the whole bridge construction time and improve the purpose of its serviceability.
Summary of the invention
This utility model provides the steel concrete combined bridge front panel of a kind of dry and wet seam, by improving precast concrete
The version of floorings so that adjusting stretch-draw transversely prestressed bars becomes with the construction sequencing pouring wet joint concrete
May, thus the transverse prestress improving concrete slab applies efficiency, reduces the cracking risk of floorings.
The steel concrete combined bridge front panel of a kind of dry and wet seam, by concrete prefabricated polylith split-type floorings splicing
Composition；Described split-type floorings both sides are teeth groove shape edge and the top flange being respectively placed in adjacent two girder steels, described
The top flange of girder steel is provided with many places cluster type weldering nail；
Adjacent two pieces of split-type floorings are spliced to form dry and wet seam due to teeth groove shape edge；Wherein, stem grafting stitches i.e. by tooth
The teeth portion docking at channel-shaped edge is formed, and wet seam is then docked, by the groove portion at teeth groove shape edge, the some slotted eyes formed and correspondence is embedding
The cluster type weldering nail being located in these slotted eyes is formed by concreting.
Described split-type floorings are completed by prefabrication, have the pipeline passed for transversely prestressed bars inside it,
It splits structure can effectively reduce the scale of construction in its making, transport, hoisting process.
Described stem grafting is sewn on job site and is coated with cementing material (such as epoxy resin etc.) and forms each piece of split-type floorings
Laterally preliminary connect.
Stem grafting to be done seam transversely prestressed bars described in post-stretching, now split-type floorings laterally only have stem grafting seam even
Connecing, transverse prestress can effectively put on floorings.
The dry and wet seam that adjacent two pieces of split-type floorings are spliced to form due to teeth groove shape edge can adjust traditional method
Stretch-draw transversely prestressed bars and the construction sequencing (pretensioning transversely prestressed bars, the after-pouring bridge that pour wet joint concrete
The wet joint concrete of panel), the transverse prestress that improve concrete slab applies efficiency, reduces the cracking wind of floorings
Danger.
Cluster type weldering nail in described wet seam is able to ensure that the overall stress of prefabricated bridge and girder steel；The most in advance should treat
After power muscle stretch-draw at described slotted eye poured in place concrete.
Described split-type floorings are connected formation entirety by dry and wet seam with girder steel.
Compared with prior art, this utility model has a following Advantageous Effects:
(1) this utility model floorings are carried out making, transporting and on-site hoisting by transverse and longitudinal piecemeal, reduce single transport
With the scale of construction of lifting, accelerate transport and the progress of lifting generally.
(2) this utility model floorings stem grafting seam defines the preliminary connection between each piece of floorings, facilitates the most pre-
Stress applies, and during Shi Hanzhang, floorings are not formed with girder steel and are stably connected with, improve concrete slab the most in advance
Stress applies efficiency, reduces the cracking risk of floorings.
(3) this utility model floorings wet seams pours after floorings transverse prestress applies, it is to avoid girder steel
The floorings loss of prestress caused.
(4) this utility model girder steel top flange weldering nail in cluster type arrange, adjust stretch-draw transversely prestressed bars with pour wet
The construction sequencing of joint concrete is possibly realized.
Accompanying drawing explanation

Fig. 2 is the floorings schematic diagram after this utility model stem grafting seam has been constructed with transverse prestress.
Fig. 3 is that the wet seam of this utility model completes the floorings schematic diagram after having constructed.
Wherein: 1-girder steel, 2-cluster type weldering nail, 3-floorings stem grafting seam, the wet seam of 4-floorings, 5-split-type bridge floor
Plate.
Detailed description of the invention
In order to more specifically describe this utility model, below in conjunction with the accompanying drawings and detailed description of the invention is to of the present utility model
Technical scheme is described in detail.
As depicted in figs. 1 and 2, the steel concrete combined bridge front panel of this utility model dry and wet seam, by concrete prefabricated
Cluster type weldering nail 2, the concrete slab stem grafting seam 3 arranged at split-type floorings 5, girder steel 1 top flange connect and concrete
The connection of floorings wet seam 4 combines.Wherein: the piecemeal fractionation of floorings can effectively reduce it and make, transports, lifted
The scale of construction in journey；The dry and wet seam of floorings can adjust traditional method stretch-draw transversely prestressed bars and pour wet joint concrete
Construction sequencing, improve concrete slab transverse prestress apply efficiency；Girder steel 1 top flange weldering nail is at floorings
Wet seam 4 corresponding position is that cluster type is arranged, the cluster type weldering nail 2 of steel reinforced concrete faying face guarantees the entirety of prefabricated bridge and girder steel 1
