Concealed Column Type Precast Concrete Member Connection Method

Abstract

The invention relates to an embedded column type precast concrete unit connecting method and belongs to the technical field of building structures. The method is characterized in that a first precast concrete unit is connected with a second precast concrete unit into one whole body; the first precast concrete unit is provided with at least one longitudinal hole in parallel to the surface, transverse grooves are formed in the longitudinal edge of the first precast concrete unit at intervals, and are crossed with the longitudinal holes outside, two side surfaces of each transverse groove are connected with longitudinal bars, and reinforcement rings are hung on the longitudinal bars; semiring-shaped reinforcements are arranged on the side surface of the second precast concrete unit, or reinforcement rings are hung on the side surface of the second precast concrete unit; the reinforcement rings of the first precast concrete unit are connected with the reinforcement rings or the semiring-shaped reinforcements of the second precast concrete unit, certain connection gaps are reserved between the reinforcement rings of the first precast concrete unit and the reinforcement rings or the semiring-shaped reinforcements of the second precast concrete unit, formworks are arranged at front and rear sides of the precast concrete units, and concrete is poured in a space formed by the formworks, the side edges of the precast concrete units, the longitudinal holes and the transverse grooves so as to connect the precast concrete units into one whole body. The embedded column type precast concrete unit connecting method can improve integrity of a precast concrete structure and promote development of the building industrialization.

Description

Technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a method for connecting a concealed column precast concrete member used for prefabricating an integral concrete structure. Background technique [0002] Precast concrete structure is a structural form suitable for industrialization, and it is the direction of housing industrialization development. The connection structure of the nodes between the precast components in the precast concrete structure determines the overall performance of the structure. The existing precast concrete structure nodes are generally weak links of the structure, which affect the mechanical performance, and the construction process is relatively complicated. Summary of the invention [0003] The invention provides a method for connecting concealed column precast concrete components with convenient construction and good stress performance. The concealed column type precast concrete comp...
