Abstract
The utility model relates to a connecting structure for a steel bar hanging rod and concrete. According to a middle-lower-bear arch bridge of a traditional steel wire tendon or steel strand hanging rod, accidents are prone to being caused due to corrosion and fatigue of the hanging rod. The connecting structure comprises the steel bar hanging rod and a concrete beam, wherein the lower end of the steel bar hanging rod is fixed to a lug plate through a bolt pin, the face of the lug plate is parallel to the longitudinal direction of the bridge, the lower portion of the lug plate is pre-buried in the concrete beam, a plurality of connecting steel plates perpendicular to the lug plate are welded to the two faces of the pre-buried part of the lug plate, and the connecting steel plates are parallel to the transverse direction of the bridge. The connecting structure for connecting the two rigid components is provided for the structure form, of connecting the steel bar hanging rod with the concrete, in a continuous beam-arch-steel bar hanging rod combined structure of a railway, and the connecting structure is reasonable in stress, definite in force transmission, convenient to construct, safe and reliable.
Description
Technical field
the utility model belongs to bridge construction technical field of buildings, is specifically related to a kind of rod iron suspension rod and concrete syndeton.
Background technology
In recent years, some adopt traditional steel tendon or steel strand suspension rod in, the lower bearing arch bridge accident that causes due to suspension rod corrosion, fatigue caused the concern of the problems such as the design of people to suspension rod and anticorrosion, inspection, replacing.For adapting to the requirement of the stressed and functional performance of beam-arch composite bridge middle hanger, must improve traditional suspension rod, adopt novel rod iron suspension rod, study itself and concrete beam connected mode, the safety of raising structure.
Summary of the invention
The purpose of this utility model is to provide a kind of rod iron suspension rod and concrete syndeton that is more suitable for beam-arch composite bridge structure.
The technical scheme that the utility model adopts is:
A kind of rod iron suspension rod and concrete syndeton, include rod iron suspension rod and concrete beam, it is characterized in that:
Otic placode is fixed on by pin in rod iron suspension rod lower end; Otic placode plate face with vertical bridge to parallel;
The bottom of otic placode is embedded in concrete beam in advance, and the otic placode two sides of pre-buried part is all welded with the multiple tracks junction steel plate vertical with otic placode, and junction steel plate is parallel with direction across bridge.
On junction steel plate, be provided with perforate, between the perforate of the junction steel plate of adjacent parallel by vertical bridge to anchor bar form shear connector.
Junction steel plate top is embedded with the horizontal fixation steel plate that is parallel to concrete beam beam face, and laterally fixation steel plate bottom surface is welded with peg;
Peg lower end is lower than junction steel plate top, and is distributed in the direction across bridge both sides of junction steel plate and vertical bridge to both sides.
Otic placode two sides is provided with the otic placode reinforcement steel plate of being close to otic placode.
The utlity model has following advantage:
The utility model is for the form of structure that in railway continuous beam-arch-rod iron suspension rod combining structure, rod iron suspension rod is connected with concrete, and the syndeton of two stiffening members of a kind of connection is provided, reasonable stress, and power transmission is clear and definite, and easy construction, safe and reliable.
Accompanying drawing explanation
