Abstract

The invention provides an I-beam for highway bridges and relates to the technical field of bridge building materials. The I-beam comprises a profile body, a positioning partition and a clamp groove; the clamp groove is arranged in a wing plate of the profile body. Two profile bodies are spliced in the width direction, and the clamp grooves may engage with the wing plates in abutting joint. The positioning partition is arranged on the side of the wing plate of the profile body far away from a web. The wing plate of the I-beam is provided with the clamp groove; the adjacent I-beams are engaged via the clap groove sand the wing plates; the problem is effectively solved that profiles easily experience vertical shift due to imbalance of stress; the positioning partition functions to secure a fireproof wear-resistant layer. On such basis, the invention also provides a composite fireproof highway bridge.

Description

technical field [0001] The invention relates to the technical field of bridge building materials, in particular to an I-beam for a fireproof road bridge and a composite fireproof road bridge. Background technique [0002] The I-beam is a kind of steel profile, which is a long strip of steel with an I-shaped cross section. The structure of the I-beam includes the upper flange, the lower flange and the web in the middle. [0003] The structural technical parameters of the I-beam include height H, width B, flange thickness tf, web thickness tw, cross-sectional area A, moment of inertia Ix, Iy, and section modulus Wx, Wy, etc. [0004] In the traditional I-beam, the upper and lower flanges are straight structures. When multiple I-beams are combined to form a stressed component, it is easy to be dislocated up and down under different pressures, which affects the bearing capacity of the component. ability. Moreover, under high pressure, the I-beam is prone to bending and saggin...
