Description
Technical field
The present invention relates to field of track traffic, more particularly to a kind of prefabricated assembled steel-HPC (High of straddle-type monorail
Performance Concrete, high performance concrete) combined track beam.
Background technology
Cross-saddle single-track traffic is different from traditional rail traffic, is shuttled among city in the form of by overpass, is one
Kind relatively new system of rail traffic, track girder are supported on pier stud, and train encircles traveling in track girder above, directive wheel with
Steady wheel is respectively acting on the top and the bottom of track girder two sides.Cross-saddle single-track traffic is high, right due to city space utilization rate
Along thread environment influence it is small, construction cost is relatively low, adapts to abrupt slope sharp turn, in Construction of Urban Rail Traffic have it is very strong
Adaptability is a kind of resource-effective, environmental-friendly system of rail traffic, will become the important side of future track transport development
To.
Traditional straddle-type monorail steel-mixes combined track beam top and cast-in-place concrete, two coxostermum of steel case is used to extend to
Back wraps up concrete, in concrete coagulation hardening process and there are problems that contraction under effect of environmental temperature, for increasing outside
The HPC (high performance concrete) of water-reducing agent is imitated, contraction problem is more serious, since cast-in-place concrete is in package about pencil
State, can not free shrink, the stress that blockage effect generates crosses senior general and leads to concrete cracking, influences the durability of structure and complete
Property, meanwhile, lower part uses steel box structure, and due to material sex differernce, expanding with heat and contract with cold for steel is asynchronous in concrete, causes cast-in-place
The joint face of concrete and steel generates additional stress, keeps inherently weaker joint face stress more complicated, makes coagulation
Soil easy tos produce crack, or even comes to nothing, meanwhile, field cast-in-place concrete, construction technology is complicated, influences the construction period, matter of constructing
Amount is also difficult to be protected.
Invention content
It is an object of the invention to overcome the existing straddle-type monorail steel-in the presence of the prior art to mix combined track beam
In concrete coagulation hardening process and there is contraction in structure, under effect of environmental temperature since cast-in-place concrete is in packet
Wrap up in restrained condition, can not free shrink, the stress that blockage effect generates crosses senior general and leads to concrete cracking, influences the durable of structure
Property and integrality, lower part use steel box structure, due to material sex differernce, expanding with heat and contract with cold for steel is asynchronous in concrete, causes
The joint face of cast-in-place concrete and steel generates additional stress, keeps inherently weaker joint face stress more complicated, makes
Concrete easy tos produce crack, or even the above-mentioned deficiency come to nothing, and provides a kind of prefabricated assembled steel-HPC combinations of straddle-type monorail
Track girder.
In order to achieve the above-mentioned object of the invention, the present invention provides following technical schemes：

It is bad, this structure setting of top plate is sealedly attached to using prefabricated HPC plates, steel case is with prefabricated HPC board groups at a confined space, energy
Enough it effectively prevent erosion of the external environmental factor to steel case internal structure.
Preferably, structural silicone adhesive sealed connection is filled between all prefabricated HPC plates and the top plate.
Preferably, each wet seam crossing is correspondingly provided with a connecting plate, and the both ends of each connecting plate connect respectively
It is connected on two structural slabs, each connecting component is set along structural slab described in the corresponding connecting plate and its both ends
It sets.
Using this structure setting, the bonding strength between each connecting component and steel case is increased, it is pre- to increase
Bonding strength between HPC plates and steel case processed.
Preferably, each connecting component includes several shearing pegs, the shearing peg on the connecting plate
Spaced set.
Preferably, the end face that each prefabricated HPC plates are connect with the wet seam is equipped with several extension lengthways main steel bars,
All extension lengthways main steel bars stretch into the corresponding wet seam.
Preferably, the extension lengthways main steel bar in the two neighboring prefabricated HPC plate end faces corresponds to overlap joint setting.
Preferably, the wet seam crossing, the extension lengthways main steel bar, which has with the design position of the shearing peg, to conflict,
When arranging the shearing peg, misplaces and arrange with the extension lengthways main steel bar on the prefabricated HPC plates, this is can
Control.
Preferably, further include drip, the width of the prefabricated HPC plates is more than the width of the top plate, the prefabricated HPC
Plate two bottom sides stretch out the top plate, and the prefabricated HPC plates base projection is respectively set the drip, prevents
Rainwater flows to bottom along the prefabricated HPC plates side wall, then flows to the top plate of the steel case and the web again, and opening
It is piled up in the intersection of the prefabricated HPC plates and the steel case under the action of power, the steel case is caused to corrode.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1, with a kind of prefabricated assembled steel-HPC combined tracks beam of straddle-type monorail of the present invention, steel boxboard part,
Prefabricated HPC plates can be used that batch production standard is quick prefabricated, greatly reduces the cast-in-place risk for generating a large amount of contraction fissures, eliminates
