Description
Technical field
The utility model relates to a kind of bridge member and its technical field of construction, especially assembled very-high performance coagulation
Soil-part shaped steel combination beam.
Background technique
Currently, conventional steel-concrete composite beam is because can make full use of the performance of steel tension, the property of concrete compression
Can, and be more and more widely used.Wherein, rolled section steel or welding steel can be used for the girder steel of conventional combination beam
Beam.Compared with welded steel beam, rolled section steel has (about the 50% of welded steel beam cost) low in cost, reduces raw material, the energy
The advantages that with artificial consumption, residual stress is low, and fatigue strength is high, appearance and good surface quality.
Since normal concrete tensile strength is low, normal concrete floorings are preferably constantly in pressured state, it is desirable that combination
Neutral axis of the beam is located within the scope of girder steel section, therefore steel beam structure height is generally higher than girder knot in conventional steel-concrete composite beam
2/3rds of structure height, and concrete slab (beam) is highly less than the one third of main beam structure height, and current fashioned iron is most
Big height is 1 m, and the self weight of normal concrete floorings is larger, and the across footpath of conventional shape steel-concrete combined beam is more than 20 m
After, the steel using amount of fashioned iron can significantly increase, and the quantity of wet seam can obviously increase, and economy is deteriorated, and assembling level is relatively low,
Lose the advantage using fashioned iron.Therefore, the economic and practical across footpath of conventional shape steel-concrete combined beam is mainly within 20 m.
Ultra-high performance concrete (UHPC) is a kind of high compressive strength, high-tensile, high ductility, the superelevation of high-durability
Performance fibers enhance cement-base composite material.Existing engineering experience show ultra-high performance concrete can effectively mitigate dead load,
Improve the utilization efficiency of structure.Normal concrete floorings, shape are substituted using the ultra-high performance concrete floorings of high-strength light
The light-duty combination beam of Cheng Gang-ultra-high performance concrete has from heavy and light, intensity is high, durability is good, structure height is low, assembly rate
High advantage.But finished product rolled section steel height maximum currently on the market is only 1 m, using steel main beam and very-high performance coagulation
The economic and practical across footpath of ultra-high performance concrete-part shaped steel combination beam that native floorings are formed still is difficult to break through 30 m.
Therefore, in order to make full use of, fashioned iron is low in cost, fatigue strength is high and ultra-high performance concrete is high-intensitive and high-ductility
The advantages that property, and the economic and practical across footpath of fashioned iron-ultra-high performance concrete composite beam bridge is expanded, develop assembled very-high performance
Concrete-part shaped steel combination beam and its construction method.
