Embodiment
The utility model is described in further details with specific embodiment below in conjunction with the accompanying drawings.A kind of bridge assembled
Steel anticollision barrier, including multiple guardrail sections along long assembling, the guardrail section include listrium 1 and web 2；Listrium 1 includes bottom
Portion is fixed on left border plate 11 and right border plate 13 on steel box-girder top plate 4, and left border plate 11 and the top of right border plate 13 pass through apical margin plate 12
It is fixedly connected；Multistage web 2 is perpendicularly fixed at the inwall of left border plate 11 and right border plate 13.
As shown in figure 1, the guardrail section of the present embodiment, which includes being fixed on steel box-girder, chooses side guardrail section at arm 3, side guardrail section
The middle listrium towards on the outside of bridge is plane vertical plate, is multistage plate towards bridge inner side listrium, it is included from bottom to top sequentially
The vertical section of connection, oblique outward segment and ramp up section.The inwall of apical margin plate 12 of the side guardrail section is vertically and fixedly provided with epiplastron.
As shown in Fig. 2 the guardrail section of the present embodiment includes the middle guardrail section for being fixed on the middle part of steel box-girder 5, middle guardrail section
Left border plate 11 and right border plate 13 are the multistage plate of symmetrical structure, its vertical section for including being sequentially connected with from bottom to top, in the diagonal
Section and ramp up section.
Steel anticollision barrier working procedure is：Pretreatment-part blanking-processing bending-unit piece manufacture-spelling
Dress up type, application-on-site hoisting-welding forming.Compared with conventional concrete guardrail, in steel anticollision barrier technological process from
Pretreatment is carried out to assembly shaping, application in factory, and the early stage construction of anticollision barrier can be processed with guardrail in factory
Carry out, effectively saved the engineering time simultaneously, steel anticollision barrier only needs to carry out lifting construction at the scene, belongs to assembled knot
Structure.Steel anticollision barrier can be saved to 1 day in the engineering time of building-site.
Listrium, web, diaphragm plate unit piece carry out assembly in factory, and arrangement meets the linear assembled tire of steel box-girder first
Frame, steel guard rail assembly work progress on assembled moulding bed, first welds together web with listrium, then by web and listrium
Sub-assembly welds together with diaphragm plate, and carbon dioxide gas arc welding thermomechanical is small, simple operation, welding quality are high, because
The connection of this steel guard rail uses carbon dioxide gas arc welding, is manufactured during manufacture using merogenesis, is carried out according to mono- section of standards of 6m
Merogenesis, it is therefore an objective to after being completed in convenient transport and on-site hoisting, field, at the construction field (site), it is only necessary to internal curtain plate, tabula
Plate docks angle welding with steel box-girder top plate and welded, and steel guard rail on-site installation work is to complete, without other processes.
Anticollision barrier abandons original reinforcing bar+concrete structure form, and the present embodiment is protected using Q345qB steel plates as steel
Column former material, anticollision barrier outsourcing listrium uses 12mm steel plates, and sets thickness to be that the continuous webs of 8mm are put more energy into listrium, steel
Anticollision barrier interval 1m processed sets one of thickness 10mm diaphragm plate.Can guaranteed steel using the combining structure of web+diaphragm plate
Anticollision barrier rigidity, the anticollision barrier after improvement, its tensile capacity is effectively improved, and is suitable in work progress the presence of cantilever position
Special operation condition.
The listrium of steel guard rail is made up of the steel plate at the left and right sides and top, and the listrium on the outside of the guardrail of side is elongated structure,
The listrium of inner side is located at the listrium 600mm of inner side using processing bending, vertical section, bending size radius 255mm arc length 640mm,
Oblique outward segment and ramp up section are located at the listrium 835mm of inner side, and bending size is radius 125mm arc length 76mm, and inner side listrium is whole
Body is " L " shape, and the inside and outside listrium handled well is welded together, and forms listrium entirety, overall low wide and up narrow, adds anticollision
The steadiness of guardrail.The listrium of middle guardrail section both sides is identical with the inner side listrium structure of side guardrail.During steel guard rail diaphragm plate blanking
Cutting out perforate at web and preheating embedding line position, both sides each reserved 3 is easy to web to install, diaphragm plate centre position bore size root
Determined according to preheating embedding line size.
Listrium is by processing bending, it is ensured that anticollision barrier profile is integrally unified, and listrium is the skeleton of steel guard rail, plays connection
The effect of diaphragm plate and web and force balance, while when installing at the scene, inside and outside listrium and steel box-girder top plate angle welding are steel
The main fixed connection mode of guardrail and steel box-girder, steel guard rail diaphragm plate ensures steel guard rail lateral stability, bears horizontal horizontal loading,
Diaphragm plate is also connected with steel box-girder top plate using carbon dioxide gas arc welding angle welding, plays a part of affixed steel guard rail, abdomen
Plate act as resistance shearing, it is ensured that the globality of steel guard rail.
