Abstract
The utility model discloses a rigid wedge-shaped block for empty and solid web connection of a truss type combined arch bridge. The rigid wedge-shaped block comprises a jaw transverse baffle (1) connected with upper string beams (7) and lower string beams (8) and a jaw end baffle (4) connected with a solid web section (120, wherein the jaw transverse baffle (1) is connected with the jaw end baffle (4) through an upper string base plate extending plate (2) and a lower string top plate extending plate (3). According to the rigid wedge-shaped block, the structure of which the rigidity of the section is changed at an empty and solid web connection position in the prior art is converted into a force transmission structure capable of achieving a rigid domain effect by the rigid wedge-shaped block, and inner force is uniformly conveyed to the upper string beams, the lower string beams and the solid web section through the jaw transverse baffle and the jaw end baffle, so that the force conveying path of a jaw of the truss type combined arch bridge is obvious, and stress on the whole jaw region is optimized; cracks in the empty and solid web connection position of the truss type combined arch bridge are prevented; and potential quality hazard is avoided. The structure is easy to implement; and the quality is easy to guarantee.
Description
Technical field
The utility model relates to a kind of rigidity wedge for the empty real abdomen handing-over of composite truss arch bridge, belongs to composite truss arch bridge structure technical field.
Background technology
In the design of composite truss arch bridge, owing to having the abrupt change of cross-section and complex structure, make stress herein complicated in the real abdomen junction of sky (being commonly called as tiger’s jaw).In the design of existing composite truss arch bridge, only at tiger’s jaw main truss sheet place, diaphragm is set one, do not take any construction measure for raising middle flask.Owing to there being the rigidity of section sudden change, the power transmission of structure is inhomogeneous continuously, causes the easy cracking in this position.
Summary of the invention
The purpose of this utility model is, a kind of rigidity wedge for the empty real abdomen handing-over of composite truss arch bridge is provided.To improve the force transferring structure of the empty real abdomen of composite truss arch bridge junction, prevent the empty real abdomen of composite truss arch bridge junction appearance cracking, cause hidden danger of quality.To overcome the deficiencies in the prior art.
The technical solution of the utility model:
Be connected with lower edge top board extension board through the base plate extension board that winds up between the tiger’s jaw place endplate that the rigidity wedge that is used for the empty real abdomen handing-over of composite truss arch bridge comprises the tiger’s jaw place's diaphragm that is connected with lower-cord beam with the beam that winds up and is connected with real abdomen section, tiger’s jaw place diaphragm and tiger’s jaw place endplate.
In aforementioned rigidity wedge, described tiger’s jaw place diaphragm all arranges with the beam that winds up is vertical with tiger’s jaw place endplate, and diaphragm top, tiger’s jaw place is connected with the top board of the beam that winds up, and diaphragm bottom, tiger’s jaw place is connected with the base plate of lower-cord beam; Endplate top, tiger’s jaw place is connected with real abdomen section top board, and endplate bottom, tiger’s jaw place is connected with real abdomen section base plate; The width of tiger’s jaw place diaphragm and tiger’s jaw place endplate is corresponding with the width of wind up beam and lower-cord beam.
Compared with prior art, be connected with lower edge top board extension board through the base plate extension board that winds up between the tiger’s jaw place endplate that the utility model comprises the tiger’s jaw place's diaphragm that is connected with lower-cord beam with the beam that winds up and is connected with real abdomen section, tiger’s jaw place diaphragm and tiger’s jaw place endplate.With the structure of rigidity wedge of the present utility model as the empty real abdomen handing-over of composite truss arch bridge, make the force path of composite truss arch bridge tiger’s jaw obvious, optimized the stressed of whole tiger’s jaw zone, prevented that cracking from appearring in the empty real abdomen of composite truss arch bridge junction, causes hidden danger of quality.Structure of the present utility model is easy to realization, and quality easily is guaranteed.
