Description
Technical field
The utility model relates to a kind of quick spelling bridge, particularly relates to the quick spelling bridge of a kind of sectional type modularization.
Background technology
Earthquake is as a kind of paroxysmal natural calamity, have time of origin short, involve wide, cause the serious characteristics of disaster degree.Ruinous earthquake usually causes bridge collapse, causes interruption of communication, brings many obstacles for the post-earthquake emergency response rescue work.Highway communication is the important channel of earthquake calamity emergency management and rescue personnel and Material Transportation, is the traffic lifeline in disaster area.Robbing fast and lead to the lifeline of interrupting because of earthquake, is important content and the key link of rescue and relief work.In robbing logical lifeline work, the major obstacles such as the bridge that often needs to adopt the method for setting up make-shift bridge to cross over to interrupt or road.
Existing make-shift bridge is take the interim steel bridge of truss-like (Bei Leishi) as main.Domestic existing " 321 " Combat Readiness Steel Bridge and HD200 type assembly type steel bridge on highway are to develop on the basis of Bailey beam bridge made in Great Britain.The imitative Britain's " Bailey bridge " of China's sixties in 20th century has developed the truss-like highway steel bridge, and the unit such as Engineering Scientific Research ﹠ Design Inst., Guangzhou Military Area improved afterwards, has formed in present " 321 " Combat Readiness Steel Bridge of typing, and people are called " Bailey bracket " usually.HD200 type assembly type steel bridge on highway (being called for short 200 shaped steel bridges), on the basis of " 321 " steel bridge, with reference to light (compact) 200 shaped steel bridges of Britain Mei Bei company, by the Combat Readiness Steel Bridge of new generation of China Communication Highway Programme Design Inst design and development.Characteristics such as that although the interim steel bridge of this type of truss-like has are simple in structure, convenient transportation, carrying capacity are large, it sets up assembly unit wastes time and energy, inconvenience emergent setting up in emergency circumstances, and its deadweight is also larger, is not easy to light transportation
Except the interim steel bridge of truss-like, also have and adopt shaped steel etc. to set up the simple and easy temporary steel suspension bridge that forms, as adopt temporary steel pile tube or steel-wire stone etc. to do the basis, and i-shape steel beams etc. are as interim longitudinal and cross beam, and steel plate or plank etc. are as the temporary steel suspension bridge of interim bridge floor vehicle-driving.Although simple and easy temporary steel suspension bridge is drawn materials flexibly, it is set up often needs long time, is not suitable for the emergent urgent need of earthquake calamity.
In general, the characteristics of existing temporary bridge technology are that rod member is many and complicated, conduct oneself with dignity also larger, and construction is set up and wasted time and energy the needs of in emergency circumstances emergency repair after generally being unsuitable for shaking.
Along with continuous evolution and the development of modern Bridge Types, corrugated steel with its preferably structural stability in steel work and steel-concrete combined structure, obtained certain application.The shearing of corrugated steel web beam is born by web fully, and the destruction of steel web is by buckling strength control, when ripple is closeer, by the complete buckling strength control; When ripple is dredged, by the cripling strength control; And in the flexing process, might be accompanied by the synthetic flexing of complete buckling and cripling.Utilize the finite element analysis of ABAQUS further to verify above-mentioned conclusion, and can with correlation test quite well as a result.The beam test of steel edge of a wing corrugated steel web beam shows, the destruction of steel edge of a wing corrugated steel web beam all is the surrenders that start from the top flange, finally cause the buckling failure of web, corrugated steel web can be ignored to the contribution of anti-bending bearing capacity, and bending and shearing does not interact in the beam.Finite element analysis to flat steel web beam and vertical corrugated steel web beam shows, adopt the steel web beam of vertical bellows-shaped, its ultimate bearing capacity obviously improves, identical stride the footpath with identical ultimate load under, adopt vertical corrugated steel web beam can reduce to conduct oneself with dignity about 10% than flat steel web beam.Therefore, in emergent bridge design, that adopts the corrugated steel structure can obtain higher buckling stability.
Steel plate (or high strength alumin ium alloy) filled board is by the steel sheet surface layer and sandwich of layers is bonding forms, surface layer provides bending resistance and shear resistance, cellular sandwich of layers works to improve buckling structure stability, the too early flexing unstable failure of steel plate has been avoided in this combination, the intensity of steel plate is given full play to, can adopt thinner steel plate design, thereby alleviate the weight of structure.The sandwich of layers shape can adopt cellular or sinusoidal waveform, and the sandwich of layers material can adopt aluminium alloys or FRP material, and the bonding of sandwich of layers and surface layer adopts high-strength epoxy glue to realize.Therefore, in emergent bridge design, that adopts steel plate (or high strength alumin ium alloy) sandwich construction can obtain higher buckling stability, and can alleviate in a large number construction weight.
The CFRP(carbon fibre reinforced composite) as a kind of new structural material, is widely used in the Structural Engineering field.The most outstanding advantage of CFRP material is that it has very high specific strength, i.e. usually said high-strength light.In bridge construction, adopt CFRP material substitution traditional material can greatly alleviate dead load, increase supporting capacity and span ability.The CFRP plate is generally linear elasticity, fragile material, and the stressed anisotropic that is is in the node junction of stressed complexity structure difficulty.Steel plate is elastic-plastic material, and the stressed isotropic that is is in the node junction of stressed complexity simple structure.With the laminated composite materials that CFRP plate and steel plate combine, can learn from other's strong points to offset one's weaknesses, can bring into play better their common advantage by combination.Simultaneously, can solve CFRP by the mechanical connection method of steel plate and connect hard problem, make the utilization of CFRP more effective.Therefore, in emergent bridge design, adopt CFRP-steel plate laminated composite materials improving structural-load-carrying capacity, when increasing structural span, alleviate the weight of structure.
Prestressed steel structure is a kind of Novel engineering structure that development in recent years is got up, at hanging structure.Rope net, rope film, cable dome structure all have the application of prestressed steel structure technology in the beam string structure etc.Prestressed steel structure can make the drawing of steel, Compressive Strength be fully used simultaneously, rigidity that can also adjustment structure, and effectively saving steel increases structural stability, reduces malformation.Therefore, in emergent bridge design, adopt prestressed steel structure also can improve structural-load-carrying capacity, when increasing structural span, alleviate the weight of structure.
Because the defective that above-mentioned existing make-shift bridge exists, the utility model people is based on being engaged in for many years abundant practical experience and professional knowledge of this type of product design manufacturing, and the utilization of cooperation scientific principle, positive research and innovation in addition, to founding the quick spelling bridge of a kind of sectional type modularization, can improve general existing make-shift bridge, make it have more practicality.Through constantly research, design, and through after repeatedly studying sample and improvement, finally create the utility model that has practical value.
