Concrete beam end and curved surface shear wall construction joint disposal device and method

Abstract

The invention relates to a concrete beam end and curved surface shear wall construction joint disposal device. The concrete beam end and curved surface shear wall construction joint disposal device comprises a concrete beam and a concrete shear wall. A construction joint is formed in the junction of the end of concrete beam and the concrete shear wall. A section steel shear resisting key is pre-embedded in the construction joint and penetrates through the construction joint, one part of the section steel shear resisting key is located in the concrete shear wall, and the other part of the section steel shear resisting key is located in the concrete beam. The invention further relates to a concrete beam end and curved surface shear wall construction joint disposal method. According to the concrete beam end and curved surface shear wall construction joint disposal device and method, due to the fact that the section steel shear resisting key is embedded, the high shear resistance of the section steel shear resisting key and the feature that anchor bars are welded on the section steel shear resisting key are utilized to solve the problem of force transmission between beam-shear wall joints; and due to the fact that a dense-hole steel wire mesh serves as a formwork of pouring of the construction joint, the penetration of rebars of the concrete beam and the section steel shear resisting key is facilitated, the adhesion force of the construction joint is increased, the construction measure cost is saved, the construction period is shortened, and the concrete beam end and curved surface shear wall construction joint disposal device and method have certain engineering application value for spatial abnormally-shaped concrete beam construction.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a device and method for treating construction joints between concrete beam ends and curved shear walls. Background technique [0002] With the rapid development of social economy, people's requirements for the function and appearance of buildings are constantly improving, and there are more and more complex structures with special shapes in space, making construction more and more difficult, especially the quality of construction joints directly affects the quality and quality of the entire building structure. Safety. The construction joints of the existing reinforced concrete beams are usually set at the 1 / 3 position of the beam span, but some special-shaped structures, especially the spiral surface structure of the outer ring and the closed curved surface shear wall structure of the inner cylinder cannot be poured at the same time, and the conventional construc...

The construction joints of the existing reinforced concrete beams are usually set at the 1 / 3 position of the beam span, but some special-shaped structures, especially the spiral surface structure of the outer ring and the closed surface shear wall structure of the inner cylinder cannot be poured at the same time, and the conventional construction method is adopted. The joint treatment method cannot meet the construction quality requirements
