Abstract
The utility model discloses a novel reinforced concrete of thermal power plant box prestressing force fortune coal strage way arranges the curve prestressing steel who adopts the stretch -draw of posttension daraf respectively at plank road roof and plank road bottom plate. Curve prestressing steel's both ends are respectively by stretch -draw end ground tackle, the anchor of stiff end ground tackle at plank road roof or the both ends of plank road bottom plate along plank road length direction. The utility model discloses adopt the post stretching to arrange curve prestressing steel on the upper portion of the lower part of plank road roof and bottom plate, the moment of flexure that produces can be offset to reverse moment of flexure that negotiating curve prestressing steel applyed under the normal load -bearing condition of plank road, reduce the moment of flexure of plank road roof and bottom plate effectively, avoids fissured appearance simultaneously, reduce concrete member's section size, saved the quantity of reinforcing bar and concrete, can greatly reduced engineering cost.
Description
Technical field
The utility model relates to a kind of Novel fire power plant's armored concrete box prestressing force fortune coal strage road.
Background technology
For superhuge coal fired power generation unit, defeated coal strage road has the design feature that buried depth is dark, span is large, be subject to larger top and two lateral earth pressures, when designing, defeated coal strage road conventionally adopts the version in armored concrete box cross section, and in the time of load and span increase, reinforced concrete structure only has by the method for the sectional dimension of increase member or increase amount of reinforcement controls crack and distortion. Obviously, in this current structural design for both uneconomical scopes of application that also limits reinforced concrete structure of way of large-span structure.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of Novel fire power plant's armored concrete box prestressing force fortune coal strage road, the problem existing to solve prior art.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of Novel fire power plant's armored concrete box prestressing force fortune coal strage road, is furnished with respectively at plank road top board and plank road base plate the curved prestressing force reinforcing bar that adopts post-tension stretch-draw.
The two ends of described curved prestressing force reinforcing bar are anchored at plank road top board or the plank road base plate two ends along plank road length direction by stretching end ground tackle, stiff end ground tackle respectively.
At the reserved cave of the plank road top board at stretching end ground tackle place or the end of plank road base plate mould, stretching end ground tackle is fixed in the mould of described reserved cave.
Described stretching end ground tackle adopts I class strand tapered anchorage.
Described stiff end ground tackle adopts I class Extrusion anchor ground tackle.
The utility model adopts post stretching to arrange curved prestressing force reinforcing bar in the bottom of plank road top board and the top of base plate, the reverse bending moment applying by curved prestressing force reinforcing bar, can offset the moment of flexure producing under the normal load-bearing condition of plank road, effectively reduce the moment of flexure of plank road top board and base plate, avoid the appearance in crack simultaneously; Reduce the sectional dimension of concrete component, saved reinforcing bar and concrete consumption, can greatly reduce construction costs.
Brief description of the drawings
Fig. 1 is the layout schematic diagram of curved prestressing force reinforcing bar of the present utility model in plank road top board and base plate.
Fig. 2 is the structural representation of stretching end ground tackle of the present utility model.
Fig. 3 is the structural representation of stiff end ground tackle of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to Fig. 1, a kind of Novel fire power plant's armored concrete box prestressing force fortune coal strage road of the present embodiment, on the basis in conventional steel reinforced concrete box fortune coal strage road that adopts common arrangement of reinforcement 2, be furnished with respectively at plank road 1 top board 4 and plank road 1 base plate 5 the curved prestressing force reinforcing bar 3 that adopts post-tension stretch-draw.
The two ends of curved prestressing force reinforcing bar 3 are anchored at plank road 1 top board 4 or plank road 1 base plate 5 two ends along plank road 1 length direction by stretching end ground tackle, stiff end ground tackle respectively.
Stretching end ground tackle adopts existing I class strand tapered anchorage, and referring to Fig. 2, strand tapered anchorage is mainly made up of intermediate plate, anchor ring I 6, anchor plate I 7 and spiral bar I 8.
Stiff end ground tackle adopts existing I class Extrusion anchor ground tackle, and referring to Fig. 3, Extrusion anchor ground tackle is mainly made up of anchor ring II 10, anchor plate II 11 and spiral bar II 12.
The utility model adopts post stretching stretch-draw curved prestressing force reinforcing bar 3, uses unbounded prestress technology, and the members such as plank road 1 top board 4, plank road 1 base plate 5 adopt high strength unbonded prestressed concrete to build. first casting concrete, making is embedded with the member of common arrangement of reinforcement 2, and reserve corresponding duct by the position of curved prestressing force reinforcing bar 3 in member body, after the intensity (be generally not less than design strength standard value 75%) that reaches regulation until the concrete strength of member, in reserving hole channel, penetrate curved prestressing force reinforcing bar 3 and carry out stretch-draw, and utilization is embedded in the strand tapered anchorage at member two ends, Extrusion anchor ground tackle is anchored at the curved prestressing force reinforcing bar 3 after stretch-draw at the two ends of member, rely on the ground tackle of component ends that the prestressing force of curved prestressing force reinforcing bar 3 is passed to concrete, make it produce compressive pre-stress, finally in duct, pour into cement mortar, make curved prestressing force reinforcing bar 3 and concrete component form entirety. specifically stretch-draw is arranged as shown in Figure 2 and Figure 3, and stiff end ground tackle envelope is embedded in the end of member, reserved cave, the end mould 9 of stretching end ground tackle place member, stretching end ground tackle is fixed in reserved cave mould 9, needs to use same label concrete to carry out end-blocking to reserved cave mould 9 after stretch-draw completes.
The utility model is born component inside by deformed bar and is divided shearing, thereby reduces the main pulling force in concrete, increases the intensity of shear of member, reaches the object that the less concrete section of utilization bears onesize outside shearing.
Compared with conventional method, the utility model has reduced the sectional dimension of concrete component, has saved reinforcing bar and concrete consumption, can greatly reduce construction costs. Meanwhile, the utility model is easy to operate, and the feature of technology maturation, stable performance can be popularized in an all-round way.
