Problems solved by technology

For the joint form of bolt connection, there are too many bolt installation holes at the joint, which may easily cause the strength of the steel section to be reduced due to the processing of too many installation holes; for the joint form of welding connection, multiple welds meet at At the nodes, it is easy to cause stress concentration, which will be unfavorable and effective to the stress state at the nodes, will reduce the connection strength at the nodes, and affect the service life of the steel structure bridge

Embodiment 1

[0029] A steel truss bridge fabricated node connection structure, comprising a node connecting plate 1 arranged on a transverse beam 10 and located on both sides of the transverse beam 1, a node slot with an open bottom formed by the joint connecting plate and the transverse beam 2. The vertical beam 3 and the two oblique beams 4 located on both sides of the vertical beam are inserted in the node slot, and the insertion ends of the two oblique beams are each provided with a socket half frame 5 and two sockets The half-frame frame mouth and the frame mouth are oppositely connected to form a socket frame, the upper end of the vertical beam is provided with a socket pipe portion 31 inserted outside the socket frame, the node connecting plate, the socket half frame and the sleeve The connecting pipe part is provided with through holes for piercing the bolts used for connecting the node connecting plate, the socket half frame and the socket pipe part.

Embodiment 2

[0033] The difference from the above-mentioned embodiment is that an inner rib 46 is connected between the outer beam panel and the sleeve half frame, the inner rib is simultaneously connected to the horizontal connecting plate, and the sleeve pipe portion corresponds to the inner The rib is provided with a clamping groove 311. The horizontal connecting plate can be formed by directly extending forward and bending with the outer beam panel, which has high strength. The sleeve half frame can be fixed to the horizontal connecting plate in advance in the processing plant. The socket half frame may be a square frame with a square cross-section or other shapes, as long as the function of the present application can be realized, and the square frame is relatively more suitable, and the structure is relatively compact. The cooperation of the clamping groove and the inner rib plate enhances the connection strength of the end of the inclined beam on the one hand, and at the same time en...

Embodiment 3

[0035] The difference from the above-mentioned embodiment is that the transverse beam is provided with a protective member having an anti-folding surface 61 that can abut against the outer surface of the outer beam panel, and the height of the anti-folding surface in the direction of gravity is greater than that of the inner side. The distance between the beam panel and the transverse beam.

[0036] The protective component is a protective pipe, and the distance between the end edge of the inner beam panel and the sleeve half frame is equal to the pipe wall thickness of the sleeve pipe portion. The provision of the above-mentioned protective component with a specific height makes the end of the incomplete frame-shaped inclined beam difficult to break, and both sides are subject to abutment restriction, which improves the connection strength.

[0037] The distance from the socket half frame to the nearest node connecting plate is equal to the pipe wall thickness of the socket pipe p...

Abstract

The invention belongs to the field of bridges, and particularly relates to a steel truss bridge assembly type joint connecting structure; the joint connecting structure comprises joint connecting plates arranged on a transverse beam and located on two sides of the transverse beam, and a joint groove formed by the joint connecting plates and the transverse beam in a matched mode and provided with an opening in the bottom. A vertical beam and two oblique beams located on two sides of the vertical beam are inserted into the joint groove; inserting ends of the two oblique beams are each provided with a sleeving half frame, and two sleeving half frame openings and frame opening edges are matched in a butt joint mode to form a sleeving frame; an upper end of the vertical beam is provided with asleeving pipe part inserted outside the sleeving frame in a sleeving mode. The vertical beam and the oblique beams and the transverse beams are inserted through matching of the components, meanwhile,the vertical beam and the oblique beams are connected in a limiting and sleeved mode; the vertical beams and the oblique beams are buckled, the components are mutually restrained, and locking is conducted through fewer bolts, so installation of the structure is rapid and convenient, and the connection strength is high.

Description

Technical field [0001] The invention belongs to the field of bridges, and specifically relates to a steel truss bridge assembly type node connection structure. Background technique [0002] With the continuous development of urban infrastructure construction, the construction scale of road bridges continues to expand, and steel structure bridges have been widely used due to their short construction period and strong adaptability to various complex environments. Steel structure bridges mainly use various section steels connected by bolts or welding to form the main body of the steel structure bridge. The joint form of each section steel at the joint has an important influence on the stress state and the safety of the steel structure bridge. For the joint form of bolt connection, there are too many installation holes for the bolts at the joint, which easily causes the section steel to process too many installation holes, which reduces the strength of the section steel itself; for ...
