Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] This embodiment provides a box-type connecting joint, see the attached Figure 1-3 , including: joint main body 2, end sealing plate 1, transverse reinforcement rib 4, longitudinal reinforcement rib 5 and positioning pin 6;

[0023] The joint body 2 is an I-shaped beam;

[0024] The two end sealing plates 1 are respectively fixed on the longitudinal ends of the joint body 2 by welding, so that the two sides of the web of the joint body 2 form a rectangular cavity with openings on two symmetrical sides (surfaces opposite to the web); and each The end sealing plate 1 is processed with three bolt through holes B10 arranged side by side in the vertical direction and two positioning pin holes 9 opposite to the web of the joint body 2, which communicate with the corresponding rectangular cavity;

[0025] After the two positioning pins 6 respectively pas...

Abstract

The invention, which belongs to the technical field of emergency bridge equipment, discloses a box type connecting joint comprising a joint main body, end sealing plates, transverse reinforcing ribs and positioning pins. The two end sealing plates are fixed to the two longitudinal ends of the joint main body respectively, so that two symmetrical rectangular cavities with openings in the side facesare formed in the two sides of a web of the joint main body, and the side faces are opposite to the web. The two positioning pins respectively and correspondingly penetrate through two positioning pin holes of one end sealing plate of the joint main body and then are fixedly connected with the web plate of the joint main body; two transverse reinforcing ribs parallel to the end sealing plates arefixed to the two ends in each rectangular cavity respectively. The distances between the two transverse reinforcing ribs and the end sealing plates at the corresponding ends are equal. Therefore, a problem of accurate positioning in the modular bridge splicing process is solved; and the joint is simple in structure, high in operability and convenient to disassemble and assemble.

Description

technical field [0001] The invention belongs to the technical field of emergency bridge equipment, and in particular relates to a box-type connecting joint. Background technique [0002] At present, most of the bridge sections of modular bridges are connected by lug plate and pin assembly, and some are connected by C-D joints and building blocks. The connection joints between the bridge sections are the main stress-bearing components of the bridge span connection, and they need to have a high fatigue life. Therefore, in the process of bridge design, it is necessary to select a joint form with high reliability and operability according to the demand. Contents of the invention [0003] In view of this, the present invention provides a box-type connecting joint, which can solve the problem of precise positioning in the splicing process of modular bridges, has a simple structure, strong operability, and is convenient for assembly and disassembly. [0004] The present inventi...
