Description
Technical field
The utility model relates to a kind of building syndeton, and especially a kind of trestle bridge floor deformation joint syndeton, belongs to building structure technology field.
Background technology
In civil engineering construction, be transporting material, equipment, personnel and the temporary bridge facility built is called trestle, timber trestle bridge and steel trestle can be divided into according to the material difference adopted.The trestle of existing structure is normally made up of bridge pier, abutment, girder steel, springboard beam and elevation and subsidence mechanical equipment etc.The form of structure of trestle is substantially identical with the structure of traditional bridge, unlike bridge beam structure and rail level maintains static, whole crossing river channels, and the beam structure of trestle and rail level can be elevated with the fluctuation of water level, and the rail level gradient can regulate thereupon.In addition, trestle only stretches into a waters part, and the substructure of trestle is bridge pier and the abutment of concrete or steel concrete; The superstructure of trestle is plate girder or steel truss girder, and bridge pier and abutment are the structure of supporting bridge superstructure and load, and abutment pulls in shore one end, to be connected with embankment at trestle, and springboard beam is the equipment connecting trestle and ferryboat, and it enters one end of water at trestle.Because trestle self structure is formed by connecting by multiple different part, the bonding strength therefore between all parts then embodies the bulk strength of trestle, and this is also the key point of trestle weight capacity.Build in the process of trestle in installation, constructor finds, gap between two pieces of floors that trestle is adjacent is larger, easily occur upon connection rocking or unstable, this can affect stability and the safety of trestle, and is normally erected at waterborne or high-altitude due to trestle, therefore also likely occur that river is from the situation of pouring in down a chimney between two pieces of floors, can skidding be caused like this, affect the driving safety of trestle, reduce the property passed through of trestle.
Summary of the invention
For above-mentioned deficiency of the prior art, it is larger that main purpose of the present utility model is that the existing current trestle of solution exists gap between floor, easily cause the problem of rocking and pouring in down a chimney with river, and provide one to have good stability, by property also good trestle bridge floor deformation joint syndeton.
The technical solution of the utility model: a kind of trestle bridge floor deformation joint syndeton, comprise left steel frame floor and right steel frame floor, it is characterized in that, between described left steel frame floor and right steel frame floor, be connected with back-fire relief band, described back-fire relief band is U-shaped structure; Isolate steel plate is provided with above described back-fire relief band, described isolate steel plate is inverted cone-shaped structure, the bottom of described isolate steel plate is flat shape, the two ends of isolate steel plate are overlapped on left steel frame floor and right steel frame floor respectively, and the two ends of described isolate steel plate are fixed on corresponding left steel frame floor and right steel frame floor respectively by screw; Above described isolate steel plate, be also provided with protection steel plate, described protection steel plate horizontal positioned, the upper surface of described protection steel plate is with to be laid on left steel frame floor concordant with the height of the concrete base layer on right steel frame floor.
Optimally; also insulation layer is provided with between described isolate steel plate and protection steel plate; described insulation layer is made up of the glass silk floss that 50mm is thick, and described insulation layer is U-shaped structure, and the two ends of insulation layer are separately fixed on left steel frame floor and right steel frame floor.Good heat insulation effect can be played by described insulation layer.
Optimally; also waterproofing course is provided with between described insulation layer and protection steel plate; described waterproofing course forms by after the thick SBS waterproof roll overlap of two-layer 4mm, and described waterproofing course is also U-shaped structure, and the two ends of described waterproofing course are welded and fixed with left steel frame floor and right steel frame floor respectively.Rain leakage can be prevented by described waterproofing course.
Optimally, described isolate steel plate is the galvanized steel plain sheet that 0.7mm is thick, and the inclined-plane of described isolate steel plate and the angle of base plane are 30 ~ 35 °.Here adopt the setting that both sides are oblique, isolate steel plate can be made to have better retractility, certain tensile force can be born.
Optimally, the thickness of described protection steel plate is 5mm.
Relative to prior art, the utility model has following beneficial effect:
1, there is good stability: trestle syndeton of the present utility model adopts the connection of sandwich construction; there is double-deck steel plate protection; stability after connection is very good; solve the problem that trestle is uneven and rocks; make each floor can connect rear formation entirety, improve overall stability.
2, safety is good: owing to being provided with back-fire relief band, the insulation topping such as silk floss and waterproof roll in sandwich construction, therefore has the effect of fire prevention, waterproof and insulation, improves the use safety of trestle greatly.
3, good by property: because the connection between each floor is more steady, to define an entirety, therefore vehicles or pedestrians by time more smoothly, reduce the amplitude of rocking, therefore there is the well property passed through.
