Different-direction steel beam oblique crossing waist rib connecting structure and connecting method thereof

Abstract

The invention provides a different-direction steel beam oblique crossing waist rib connecting structure and a connecting method thereof. The different-direction steel beam oblique crossing waist rib connecting structure comprises a main beam and a secondary beam which are crossed in different directions, wherein a main beam waist rib parallel to the main beam is disconnected at the joint of the main beam waist rib and the secondary beam and fixed to the two corresponding sides of the secondary beam through connecting plates, and a secondary beam waist rib parallel to the secondary beam is disconnected at the joint of the secondary beam waist rib and the main beam and fixed to the two corresponding sides of the main beam in a bent anchoring mode. The anchoring problem of the main beam waistrib and the secondary beam waist rib when different-direction steel beams are crossed is solved, and the phenomenon that the aperture ratio of a steel beam web is too large is avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a connection structure of steel beams with different directions and a connecting method thereof. Background technique [0002] At present, in the steel concrete structure, there are often multiple steel beams obliquely intersecting, so that the waist reinforcement of the steel beams will be affected by the web of the intersecting beams. In the past, holes were mostly used to penetrate the reinforcement. However, when the oblique angle is large, the steel bars with ordinary openings cannot pass through, and the openings can only be enlarged. Generally, the bending moment is very large at the intersection of shaped steel beams, and it must be reinforced after the hole is opened, which affects the force of the shaped steel beam itself and also causes waste of materials. [0003] In the traditional opening, the hole diameter is generally 4mm-6mm larger than the steel b...
