Concrete structure beam-column joint rear anchoring structure and construction process thereof

Abstract

The invention relates to a concrete structure beam-column joint rear anchoring structure and a construction process thereof. The anchoring structure comprises a vertical frame beam, wherein a transverse frame beam is arranged on the left side of the vertical frame beam, longitudinal frame beams are arranged on the front side and the rear side of the vertical frame beam, an expanded section is arranged on the right side of the vertical frame beam, and a newly-added beam is connected to the expanded section, wherein a plurality of front and rear newly-added longitudinal bars are arranged in the expanded section, a plurality of newly-added stirrups are arranged on the plurality of front and rear newly-added longitudinal bars at intervals from top to bottom, a plurality of inner stirrups are arranged in the vertical frame beam at intervals up and down, and the newly-added stirrups and the inner stirrups in the vertical frame beam are bound and welded. According to the concrete structure beam-column joint rear anchoring structure and the construction process thereof, the problems that after an existing structure is reinforced, original reserved steel bars of a structural beam do not meet the load requirement of a newly-added beam plate, safety is poor, the construction cost is increased, and the construction quality is difficult to guarantee can be solved.

Description

technical field [0001] The invention relates to a post-anchoring structure of a beam-column joint of a concrete structure and a construction technique thereof, belonging to the technical field of civil engineering. Background technique [0002] In the post-anchor connection design, the failure mode should be controlled according to the type of structure to be connected, the nature of the anchor connection force and the type of anchor bolt. For the anchor connection of structural members subject to tension, edge shearing, and tensile-shear combination, and non-structural members of lifeline engineering, the failure of anchor bolts or planted steel should be controlled, and the failure of concrete base materials should not be controlled; for expansion anchors and For the anchorage connection of reaming anchor bolts, the overall pull-out damage should not occur, and the anchor rod penetration damage should not occur; for the chemically planted bars and long screws that meet the...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a post-anchoring structure of concrete structure beam-column joints and its construction technology in view of the above-mentioned prior art, which can solve the problem that the original reserved steel bars of the structural beam after the existing structure is reinforced do not meet the requirements of the newly added beam slab. Load requirements, poor safety, increased construction costs and difficulties in ensuring construction quality
