Abstract
The utility model provides a concrete sleeper shoulder with shear reinforcements. Straight grade groove shoulder is introduced and each outer shoulder of each support rail groove is provided with U-shaped shear reinforcements which are 6mm in semi-diameter. The two ends of shear reinforcements are configured to have curved gouges with a degree of 180. Since shear reinforcements are provided, when the outer shoulder is under horizontal force, the force format is the same as that of a concrete corbel. The stretch-proof intensity of the reinforcing steel bar and the press-resistant performance of the concrete are fully made used of. The two curved gouges of the U-shaped shear reinforcement are hung on the top inside inherent stress main reinforcement and are colligated and fastened by a ligating belt and are accurately positioned and then are configured to be a whole with the main reinforcement, so that shear reinforcements are anchored with credibility, thus effectively improving the shear-proof intensity of the outer shoulder.
Description
Technical field
The utility model belongs to rail track prestressed reinforced concrete tie outer blocking shoulder shear resistance to be strengthened, a kind of specifically concrete sleeper shoulder block with shear bar is fit to sweep R=500-1200M railway standard circuit III type or II type prestressed reinforced concrete tie and uses.
Background technology
According to the knowledge of the applicant: in the use of sleeper, train mainly is to be born by the sleeper outer blocking shoulder on bend or because of rocking the lateral force that forms horizontal direction.The stressed plain concrete that is of existing various concrete sleeper shoulder block is cut, and does not join any type of principal rod.Adopt the shoulder block form of straight sloping groove, change the stressing conditions of shoulder block, though reduced the horizontal force that gauge apron is delivered to shoulder block, the shear resistance of shoulder block self does not improve, and is still cut for plain concrete.
The utility model content
The purpose of this utility model is to improve the horizontal shear resistance of sleeper outer blocking shoulder, and a kind of concrete sleeper shoulder block that effectively has shear bar is provided.
The purpose of this utility model is to adopt following technical solution to reach: be included in the prestressed reinforcement of setting in the concrete sleeper and the stirrup of end thereof, promptly adopt straight sloping groove shoulder block, shear bar at each rail support groove outer blocking shoulder position configuration Φ 6mm, shear bar is the U type, and its two ends all have 180 ° curved ditch.
The shear bar of described configuration Φ 6mm is twice.
Two curved ditches of described U type shear bar are to be suspended on the main muscle with pricking silk to connect firmly and accurately location of a colligation, with main muscle be an integral body.
The beneficial effects of the utility model:, give full play to tensile strength of reinforcement, the performance that concrete compression intensity is good because the stressing conditions when being provided with shear bar and making outer blocking shoulder be subjected to horizontal force becomes the same stress form of concrete bracket; Two curved ditches of U type shear bar are suspended on two inboard prestressing force master muscle of last row, use the bundle silk to connect the firmly also accurate location of colligation, form an integral body with main muscle, make the anchoring of shear bar reliable, have improved the shear strength of outer blocking shoulder effectively.
Description of drawings
Fig. 1 is a concrete sleeper outer blocking shoulder shear bar configuration schematic diagram of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, the utility model is included in the prestressed reinforcement of setting in the concrete sleeper and the stirrup 1 of end thereof, all dispose the shear bar 2 of twice Φ 6mm at the outer blocking shoulder position of two rail support grooves 3 of straight sloping groove-shaped sleeper for the shear resistance that improves shoulder block, shear bar is the U type, its two ends all have 180 ° curved ditch, are convenient to the installation of shear bar 2.Hang over during installation on two inboard prestressing force master muscle 4 of last row, to connect colligation firm with pricking silk, accurate with the installation site that guarantees shear bar 2, forms integral body with main muscle simultaneously, makes the anchoring of shear bar reliable.
Claims (3)
1. concrete sleeper shoulder block with shear bar, be included in the prestressed reinforcement of setting in the concrete sleeper and the stirrup of end thereof, it is characterized in that: adopt straight sloping groove shoulder block, shear bar at each rail support groove outer blocking shoulder position configuration Φ 6mm, shear bar is the U type, and its two ends all have 180 ° curved ditch.
