Fabricated concrete variable-section end-column-type shear wall member and construction method thereof

Abstract

The invention belongs to the technical field of building materials and building construction and particularly relates to a fabricated concrete variable-section end-column-type shear wall member and amanufacturing mould and construction method thereof. The fabricated concrete variable-section end-column-type shear wall member comprises a shear wall limb (11) and an end column (12), and the end column (12) is directly connected with one side end of the shear wall limb (11). Through the variable section, steel bar joints (1F) of vertical steel bars (101) on the two sides of the lower section (1B) of the member and edge member vertical steel bars (1041) are exposed. The problem of unstable connection between the vertical steel bars (101) and the edge member vertical steel bars (1041) of the end-column-type shear wall member is conveniently solved through a welding connecting method. Through an overall prefabricated mode, the problem of connection of horizontal steel bars (102) and the problem that various steel bars cannot be mutually connected to form a steel bar framework are solved. By forming a shear wall limb vertical hole channel (112) and an end column vertical hole channel (122) which are special for cast-in-place concrete (32), the cast-in-place concrete (32) is easy to pour, vibrate and compact, the quality defect is avoided, and detection and acceptance are facilitated.By arranging an L-shaped connecting beam support (105) or a connecting beam support platform (106), connecting beams or frame beams are conveniently mounted.

Description

technical field [0001] The invention belongs to the technical field of building materials and building construction, and relates to a shear wall component used in a building structure, in particular to an assembled concrete variable-section end column type shear wall component, a manufacturing mold and a construction method thereof. Background technique [0002] Assembly building is to connect the same kind of prefabricated components or different kinds of prefabricated components. Since the reinforced concrete shear wall is integrated with concrete and steel bars, it is necessary to solve the connection problem of the longitudinal and vertical reinforcement of the shear wall, especially the shear wall. The connection problem of the vertical reinforcement at the bottom. At present, the connection of the vertical reinforcement at the bottom of the prefabricated reinforced concrete end-column shear wall mostly adopts the sleeve grouting method, and there are many problems. The...

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing technology, it is difficult to stagger the horizontal reinforcement joints of the large amount of cast-in-place cast-in-place concrete variable-section end-column shear wall components at present, and the sleeve connection of vertical reinforcement is not firm and the operation is inconvenient. The quality is difficult to guarantee. The steel bars of the end-column shear wall components do not form a steel bar skeleton. The first purpose of the present invention is to provide an assembled concrete variable-section end-column shear wall component. By improving the prefabricated concrete variable-section end-column type For the structural design of shear wall components, the cross-section of the prefabricated reinforced concrete variable-section end-column shear wall components is changed, and the vertical reinforcement protruding from the lower part of the upper section of the exposed component on both sides of the exposed component and the vertical reinforcement of the edge component are adopted. The traditional and simpler welding connection method of steel bars solves the connection problem of vertical steel bars of end-column shear wall members and vertical steel of edge members; the method of integral prefabricated prefabricated concrete variable-section end-column shear wall members solves the problem of horizontal steel bars Connection and various steel bars can not be interconnected to form a steel skeleton problem; the method of reserving a special vertical channel for cast-in-place concrete is adopted to ensure that the concrete is poured and vibrated compactly during on-site installation; the second purpose of the present invention is to provide a A manufacturing mold for a prefabricated concrete variable-section end-column shear wall component; the third purpose of the present invention is to provide a construction method for a prefabricated concrete variable-section end-column shear wall component to solve the problem of prefabricated reinforced concrete The use of molds for cross-section end-column shear wall components and the production and installation methods of end-column shear wall components
