Embodiment Construction

[0010] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] Such as figure 1 Shown: the lower side of the bottom horizontal member 1 of the thin steel plate shear wall is welded with anchors 2 arranged vertically and evenly spaced. The anchors 2 are arranged along the length centerline of the horizontal member and embedded in the foundation concrete. Shear keys 3 are respectively welded on the parallel front and rear surfaces of the horizontal member, and the shear keys are evenly spaced. The anchors shown in the figure are I-beams, and steel plates and channel steels can also be used to arrange any interface steel. The anchorage length is determined according to calculation. Through the gaps of each anchor piece, the foundation reinforcement is arranged through. The shear key 3 can adopt a stud or a truncated steel bar head, which improves the gripping ability of the anchor in concrete. ...

Abstract

The invention discloses a connected node of a horizontal member and a foundation of a thin steel-plate shear wall, which belongs to the field of architectural construction engineering, and comprises a horizontal member (1) and a foundation of a thin steel-plate shear wall. The connected node disclosed by the invention is characterized in that anchoring members (2) which are uniformly arranged and welded at a certain interval along the lower length centerline of the horizontal member (1) at the bottom layer are vertically buried into the foundation, a shear key (3) is respectively welded on the front and rear side surfaces (parallel to the horizontal member (1)) of the anchoring members (2), and the shear keys (3) are uniformly arranged at a certain interval. The technical problem solved by the invention is to provide a new connected node, and the node greatly enhances the anchoring capacity (namely, pullout resistant capacity) of the anchoring members (2), thereby effectively balancing a tension field generated by a bottom thin steel-plate shear wall.

Description

technical field [0001] The invention belongs to the field of building structure engineering, and in particular relates to a foundation connection node in a thin steel plate shear wall. Background technique [0002] The steel plate shear wall structure is a new type of lateral force resistant member structure system developed in the 1970s. With the research of steel plate shear walls, the currently used steel plate shear walls are divided into thick steel plate shear walls and thin steel plate shear walls. According to the current research, the mechanical mechanism of thick and thin steel plate shear walls is mainly distinguished according to whether the post-buckling strength of the steel plate is used. The thick steel plate relies on the shear stiffness of the steel plate to resist the horizontal force, and the steel plate remains elastic all the time. This design prevents the actual strength of the steel plate from being fully utilized, while the thin steel plate utilizes...
