Preferably, in described double-deck corrugated steel arch bridge: form a plurality of horizontal splicing seams after described polylith corrugated steel splicing, adjacent horizontally-spliced seam is not on same straight line.
Preferably, in described double-deck corrugated steel arch bridge: described corrugated steel is the steel plate that is electroplate with the zinc topping.
Preferably, in described double-deck corrugated steel arch bridge: the surface of described corrugated steel is provided with polyethylene or epoxy resin anticorrosive coat, is preferably high density polyethylene.
Double-deck corrugated steel arch bridge of the present utility model has following advantage and beneficial effect: the corrugated steel arch bridge is to process the corrugated steel assembly at factory floor in advance according to design drawing, is transported to the construction that on-site consolidation is completed bridge, has saved the engineering time; The corrugated steel spandrel-braced arch bridge than conventional deck bridge be suitable for banket higher, applicable larger across the footpath; Filler is wrapped in corrugated steel inside, has reduced the corrosion of external environment condition, has extended bridge application life; Do not need a large amount of circulation materials, reduced construction cost; Required traditional building material is less, and is on-the-spot without building waste, environmental protection; The corrugated steel spandrel-braced arch bridge is a kind of flexible structure, can adapt to larger sedimentation and distortion, has certain shock resistance, has increased the security performance of bridge; The arch bridge floor, profile is more attractive in appearance.
Will be appreciated that, the feature in the above each side of the utility model can be in scope of the present utility model independent assortment, and be not subjected to the restriction of its order---as long as the technical scheme after combination drops in connotation of the present utility model.
Description of drawings
Below in conjunction with drawings and Examples, the double-deck corrugated steel arch bridge of the utility model is described further, in accompanying drawing:
Fig. 1 is the structural representation of the double-deck corrugated steel arch bridge of the utility model;
Vertical schematic diagram of Fig. 2 a corrugated steel of the present utility model;
The view in transverse section of Fig. 2 b corrugated steel of the present utility model;
The connected mode schematic diagram of Fig. 3 corrugated steel of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only is used for explanation the utility model and is not used in restriction scope of the present utility model, after reading the utility model, those skilled in the art all falls within the application's claim limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, in the structural representation of double-deck corrugated steel arch bridge of the present utility model as seen: this arch bridge adopts double-deck corrugated steel to make and also fill the resistance to compression filler in the gap of double-deck corrugated steel.Particularly, the two ends of the first arch support section 1 and the second arch support section 2 are separately fixed in basic courses department 4.Different with size and/or the radian of the second arch support section 2 due to the first arch support section 1, have certain space between the two, resistance to compression filler 3 namely is filled in this space, with the bearing capacity of further enhancing bridge.
Forward Fig. 2 a and Fig. 2 b to, describe the concrete structure of corrugated steel.As seen, the surrounding of corrugated steel has fixing hole 12 from vertical top view of Fig. 2 a, is bolted between adjacent corrugated steel.As seen, the corrugated steel cross section is similar sinusoidal shape from the described view in transverse section of Fig. 2 b.Distance definition between adjacent crest or adjacent trough is the pitch of waves, and adjacent crest and the difference in height between trough are called wave height.When actual design, the numerical value of the pitch of waves and wave height is according to the concrete condition of bridge and different.
The mode that is connected and fixed of adjacent corrugated steel is described in conjunction with Fig. 3 at last.A corrugated steel 11 in the first or second arch support plate is fixing by bolt 5 with another piece corrugated steel, and is connecting filling weather-resistant glue 6 between the gap.The mode that the second above-mentioned high-strength bolt of arch support section's employing connects is carried out assembly unit, uses without the support assembly unit, and integral assembling 3 encircles on the ground in advance, adopts the form of integral hoisting that top corrugated steel arch ring is installed, and assembly unit is piecewise completed.Between arch, filler and upper corrugation steel plate arch ring synchronous construction are completed construction to full-bridge, and adjacent transverse assembly unit seam can not be on the same straight line.According to deck profile grade and predicted settlement, pre-arch is set during installation.The first arch support section adopts not Curved Corrugated steel plate materials, adopts the mode of assembly unit to install, and adopts high-strength bolt to be connected between sheet and sheet, according to deck profile grade and predicted settlement, pre-arch is set during installation.When bridge hour, can adopt a monoblock steel plate to be wound into the corrugated steel of certain radian through furling plate round machine.
In a word, corrugated steel arch bridge of the present utility model has thoroughly overcome under the condition of some high embankment or heavy load, when too high for the wall thickness selection of corrugated steel, a kind of novel arch bridge is provided, make arch bridge larger across the footpath, carried byer force, Arch Bridge Construction is simple and fast and reliable in quality more.The whole body of a bridge of the present utility model adopts the corrugated steel assembly unit of double-deck split blade type, the satisfactory filler of inner filling.The joint number of corrugated steel, thickness, ripple parameter and round diameter all can be made different choice according to demand, and this just can satisfy various across the footpath requirement, and have improved the range of application of managing variously again in environment.Double-deck corrugated steel form has promoted the bearing capacity of arch bridge greatly, and inside stuffing has effectively been born the bridge floor load, and when having strengthened across the footpath, arch formula bridge floor is good looking appearance especially.The corrugated steel goods are compared with the other materials prefabrication, have the cross section little, lightweight, be convenient to deposit that transportation, construction technology are simple, assembling fast, the advantage such as the construction period is short, can be used in medium and small arch bridge.
